The invention provides a diesel engine installation frame integrated with a fuel tank. The diesel engine installation frame integrated with the fuel tank comprises a bottom plate. A fuel tank first part, a fuel tank second part, an oil collecting groove and a shock isolator installation seat are arranged on the bottom plate. The fuel tank first part and the fuel tank second part are arranged on the bottom plate oppositely, and the bottoms of the fuel tank first part and the fuel tank second part communicate with each other. The oil collecting groove is located between the fuel tank first part and the fuel tank second part. The shock isolator installation seat is located on an installation seat. A traditional fuel tank is changed into a support where a motor and a diesel engine can be placed, and the support contains fuel oil through a support inner cavity. The surface of the support is provided with an oil return port, an oil sucking port, an atmosphere communication pipe and an oil adding port universal for existing fuel engines. The supporting force of the support is increased by arranging a transverse separating frame and a longitudinal separating frame. The installation positions of a motor installation seat and a diesel engine installation seat are arranged reasonably, so that the installation frame is stressed uniformly.

The invention relates to the technical field of oil extraction machinery, in particular to an automatic speed-changing wide-swing-angle oil pumping machine. The automatic speed-changing wide-swing-angle oil pumping machine comprises an electric motor, a speed changing mechanism, a swing arm support, a swing arm arranged on the swing arm support, a support provided with a fixed pulley and a wellhead oil pumping device, wherein the speed changing mechanism is connected with a driving crankshaft wheel, the driving crankshaft wheel is meshed with a driven crankshaft wheel, the driving crankshaft wheel is connected with a connecting piece through a bearing, one end of the connecting piece is connected with the driven crankshaft wheel, the other end of the connecting piece is connected with the swing arm through a connecting rod, a sliding chute is arranged on the connecting piece of which one end is connected with the driven crankshaft wheel, and a bearing on the driven crankshaft wheel is sleeved in the sliding chute. The automatic speed-changing wide-swing-angle oil pumping machine disclosed by the invention has the advantages that when the two crankshaft wheels are in rotation, since the position of the bearing of a driven pulley is changed, the position of the connecting piece can be also correspondingly changed, a motion trail of the connecting rod is affected by the motion of the connecting piece, the speed of the wellhead oil pumping device in the up-stroke is higher than that in the down-stroke, the oil leakage problem existing in an oil pumping process is avoided, and the oil pumping efficiency is increased.

The invention provides a horizontal well coiled tube drilling plug tubular column which comprises a milling shoe, a motor, a motor head, an anchoring and pressurizing device and a jar knocker, wherein the milling shoe, the motor, the motor head, the anchoring and pressurizing device and the jar knocker are sequentially connected. The horizontal well coiled tube drilling plug tubular column comprises the anchoring and pressurizing device which can anchor a drilling plug tubular column body into a horizontal well casing tube. After the drilling plug tubular column body is anchored into the horizontal well casing tube through the anchoring and pressurizing device, the milling shoe is pressurized to guarantee the drilling pressure of the milling shoe. The anchored drilling plug tubular column can balance the axial force generated when the milling shoe drills and removes a bridge plug, and the drilling process of the milling shoe is stable. Accordingly, the efficiency of the drilling and removing of the bridge plug is improved, and the time for drilling and removing the bridge plug is shortened.

The invention discloses a screen material for a 35kV grade high / medium voltage crosslinked cable conductor layer, which is characterized by comprising the following components in parts by weight: 40-65 parts of EVA (ethylene-vinlacetate copolyme), 5-15 parts of PE (polyethylene), 30-50 parts of conductive black, 1-5 parts of dispersing agent, 0.3-1.5 parts of antioxygen, 4-8 parts of white oil, 0.3-5 parts of lubricant and 0.7-2.5 parts of cross-linking agent. The dispersing agent is added to the screen material, which enables the distribution of the conductive black to be extremely even; the torque of an extruder is very balanced when being used, the fluctuation of the wire diameter of the cable is very small, and the pre-crosslinking phenomenon is not easy to happen. The screen material can be unremittingly extruded for a long time, which is extremely beneficial to manufacturing big-length fixed-length cables and can improve the yield. The cross-linking agent in the crosslinked screen material is a tasteless peroxide, which is more beneficial to environmental protection.

The invention relates to an improved power repair feet crawler. The improved power repair feet crawler comprises a main crawling machine; the side surface of the main crawling machine, facing an electric pole, is an arc-shaped crawling surface; universal rotating wheels are arranged at equal intervals on the crawling surface and electrically connected to a controller; a cable chute is formed in the crawling surface; a crawling cable is mounted in the cable chute, and threads are formed in the surface of the crawling cable; closed lock buckles are mounted at two ends of the crawling cable; the crawling cable is manufactured from non-stretching and bendable wearable materials; the crawling cable engages with a driving wheel; the driving wheel rotatably sleeves an adjusting shaft parallel to the electric pole; the adjusting shaft can horizontally move in an adjusting groove at the back of the main crawling machine in the radial direction of the electric pole. The feet crawler has a small size, and is convenient to carry, applicable to the electric poles of various sizes, safe and reliable, and simple to operate.

Drive device for a wind mill comprising a large pulley (21) disposed on a main shaft (22) and at least one belt (27) or chain adapted to transfer rotation from the pulley (21) to a generator (30, 31). The pulley (21) is rotationally coupled to at least two secondary shafts (23, 24), which are disposed parallel to the main shaft (22). One or more belts (27), which transfer the rotation, extend over the pulley (21) and the secondary shafts (23, 24). The secondary shafts (23, 24) are in turn rotationally coupled to at least one, preferably two, electric generators (30, 31).

The application discloses a control method and related products. The control method includes: obtaining the first target power; obtaining the target speed and target torque corresponding to the first target power according to the external characteristics of the engine; adjusting the speed of the engine according to the target speed, and adjusting the torque of the motor according to the target torque; obtaining the actual torque of the engine; When the actual torque of the engine does not match the target torque, the difference between the torque of the motor and the actual torque of the engine is adjusted within a first torque difference range. In this way, the rotational speed of the engine is adjusted while the torque of the electric motor is adjusted, and the rotational speed of the engine does not need to be adjusted after the torque of the electric motor is adjusted, thereby reducing the response time of power switching. And after adjusting the power of the engine, when the actual torque of the engine is different from the target torque, the torque of the motor is adjusted to the difference with the actual torque of the engine within the first torque difference range, so that the torque of the motor and the engine torque balance.
