The invention discloses a method for rapidly judging a wiring error of a power distribution transformer monitoring terminal. The method is characterized by comprising two steps of voltage detection and current return accuracy detection, wherein the intelligent judgment on the wiring error of the power distribution transformer monitoring terminal is realized according to the phase relationship between a three-phase voltage and a current. According to the method, the method is embedded into the terminal in mode of embedded software directly; the automatic operation can be realized when the terminal is powered on, and then the wiring error of the terminal is judged automatically; and the installation personnel are prompted through a liquid crystal interface and a buzzer; the accuracy rate of the installation is improved; and the labor waste caused by secondary construction is avoided.

The invention provides a tool box car for civil construction, belonging to the technical field of tool box cars, comprising a car body, several storage units, a sliding mechanism and a locking mechanism. Several storage units are located on the vehicle body, and all the storage units are stacked vertically. The storage unit has a storage drawer and a plurality of insertion posts, the insertion posts of the lowermost storage unit slide through the vehicle body, and the sliding posts of any other storage units slide through the adjacent storage units below. The sliding mechanism is slidably connected with the vehicle body along the vertical direction, and has an abutment shaft, which can abut with the upper surface of the storage unit of the top layer. The locking mechanism enables the abutment shaft to restrict the upward movement of the storage unit. The tool box cart for civil construction provided by the invention can avoid the inconvenience of using a portable tool box to transport tools and the problem of labor waste caused when there are many portable tool boxes to be carried.

The invention discloses a jacking device for disc-shaft flange assembling and an assembling method thereof. The jacking device for disc-shaft flange assembling comprises high strength bolts; the high strength bolts are in threaded connection with a shaft end nut flange after penetrating through a hydraulic cylinder positioning block and a disc-shaft flange platen in sequence; one end face of the disc-shaft flange platen makes contact with one end face of a hydraulic cylinder; and the other end face of the hydraulic cylinder makes contact with the hydraulic cylinder positioning block. According to the jacking device for disc-shaft flange assembling and the assembling method thereof, the combined entire jacking device is of a hollow structure; an oil pipe connector of an oil pressure expansion tool can be stretched into and fixed into a center oilhole on a shaft end of a dynamometer; the jacking device under the state of preinstalling and working plays a limiting role in the hydraulic cylinder, doesn't interfere with an oil inlet and the connector of the hydraulic cylinder, is applicable to the installation of the dynamometer shaft end and the corresponding disc-shaft flange, and effectively solves the problem that the disc-shaft flange installed by manpower is small in the magnitude of interference and bad in installation.

The invention relates to a switch for a tablet discharge of a tablet press, where a control device and a driving device are disposed. The driving device moves the switch between a first switching position and at least one second switching position according to a switching signal of the control device, and is provided with at least one sensor for detecting the first switching position and / or the atleast one second switching position is reached by the switch. The detection signal of at least one sensor is applied to the control device, and the control device is configured to, in a case in whicha switching signal for moving the switch from the initial switching position to the target switching position is present and the detection signal for the arrival of the target switching position is absent, output a switching signal for partially or completely returning the switch to the initial switching position, and then output a switching signal for moving the switch to the target switching position. The invention also relates to a rotary tablet press and a method for operating the switch.

The invention discloses an automatic cutting device for billboard manufacturing, which relates to the technical field of billboard manufacturing. A support plate is fixedly connected. Through the mutual cooperation between the first threaded rod, the worm wheel, the first pulley, the turntable, the linkage rod, the second pulley, the worm and the placing plate 1, the fixedly connected pulley 1 and the turntable can be driven by the motor to rotate at the same time, and the first pulley drives the second pulley through the belt. Rotation, the second pulley drives the coaxially connected worm to rotate, and the worm then drives the threaded rod 1 to rotate slowly through meshing with the worm wheel, so that the billboards placed on the placing plate 1 and the placing plate 2 move slowly. At the same time, the linkage on the turntable The rod drives the connecting block to move up and down, so that the connecting block drives the fixedly connected wire saw to move up and down, so as to automatically cut the billboard and avoid potential safety hazards.

The invention discloses a simple storage method of rice seeds, and the method comprises the following steps that 10 days to 15 days after a rice seed field is mature and when the seed water content reaches 20 percent to 24 percent, the seeds are harvested; the harvested seeds are air dried naturally, dried mechanically or treated by integrating the natural air drying and mechanical drying methods, so as to control the water content not to be higher than 18 percent; imperfect grains, dry leaves and grass seed impurities are removed mechanically, and the seeds are packed into woven bags by 60kg / bag; the woven bags filled with the seeds are piled and stored in a warehouse, wherein the piling method is wall-type stacking, the piling height is 5m to 8m, spaces are left around seed piles, an airway is left for every 3 to 4 woven bags on the same layer, and the airways on the upper and lower layers are staggered; the seeds are stored at room temperature, and the warehouse is exhausted for 24 hours once every month; before being sold, the seeds are mechanically dried again until the water content is 14.5 percent. According to the simple storage method of the rice seeds, the germination rate when sowing is guaranteed not to be lower than 90 percent, the conflict between high yield and insufficient mechanical drying capability in the seed harvesting season is effectively mitigated, the cost is minimized, the seed quality is ensured, and very good practicality is realized.
