The invention discloses an environment-friendly solar panel placing device comprising a base. A bearing is fixedly embedded in the middle part of the upper surface of the base, a supporting column isarranged above the base, and the outer surface of the bottom end of the supporting column is fixedly connected with the inner ring of the bearing. A sliding groove is formed in the middle of the leftside face of the supporting column, a sliding block matched with the sliding groove is clamped in the sliding groove, and a first through hole is formed in the left side of the front surface of the supporting column. The environment-friendly solar panel placing device can enable the movable block together with the solar panel to adjust the inclination angle conveniently under the action of a sliding block, a first through hole, a second through hole, a connecting rod and a universal ball by arranging the sliding groove. Under the action of a screw rod and a screw ring, the supporting column can rotate along with the solar panel by arranging the bearing, so that the inclination angle of the solar panel can be conveniently adjusted. The device can be conveniently moved by arranging rollers,so that the solar panel can be effectively prevented from shielding the solar panel, and the power generation efficiency of the solar panel is reduced.

The invention discloses a solar photovoltaic plate with the automatic dedusting and cleaning functions. The solar photovoltaic plate comprises a base, a support rod, a photovoltaic plate main body, ahydraulic cylinder and a support frame, wherein a cleaning mechanism is arranged on the support frame; side plates are arranged on the two sides of the photovoltaic plate main body; a first sliding rail is arranged at the top of the photovoltaic plate main body; a second sliding rail is arranged at the bottom of the photovoltaic plate main body; air cylinders are arranged on the two side plates; the output ends of the air cylinders are fixedly connected with push rods; dust collecting felt is connected with the corresponding push rod in a sleeving manner; the upper and lower ends of each of the push rods are connected with a first sliding block and a second sliding block separately; the first sliding block is in sliding connection with the first sliding rail; the second sliding block is insliding connection with the second sliding rail; a fixed bracket is arranged on the side, far away from each of the air cylinders, of the corresponding push rod; a first motor is mounted at the end part of the fixed bracket; a rotary bracket is arranged on the output shaft of a first motor in a sleeving manner; a second motor is mounted at the end part of the rotary bracket; and a rotary hairbrush is mounted on the output shaft of the second motor. The solar photovoltaic plate is high in cleaning effect and dedusting efficiency.

The invention provides a pushing and supporting device of a tunneling machine and a construction method. The pushing and supporting device of the tunneling machine comprises a plurality of embedded supporting anchor hole beams, at least two inclined slide tracks and a reaction frame; supporting and positioning anchor holes are formed in two ends of each supporting anchor hole beam; reaction frame supporting legs are arranged on the bottom of the reaction frame; and the reaction frame has a frame structure, and is provided with a side surface which is opposite to the end surface of the tail of the tunneling machine and is used for pressing against an auxiliary pushing oil cylinder. The construction method comprises the following steps of (1) welding an embedded bolt on a joint bar; (2) mounting a steel cushion on the embedded bolt through a nut; and (3) mounting the supporting anchor hole beams, the supporting and positioning anchor holes and the slide tracks on the steel cushion, placing the auxiliary hydraulic oil cylinder between the tunneling machine and the reaction frame, and jacking by a stepping stroke. By the steps, the tunneling machine is pushed to walk when beginning to enter a hole. By the pushing and supporting device of the tunneling machine and the construction method, hundreds of tons of stepping thrust can be ensured, and the circumstance that a slide way structure is damaged due to uneven stress can be avoided.

The invention relates to an adjustable mounting structure for wall decoration plates and a mounting method of the wall decoration plates, and relates to the technical field of indoor decoration. The adjustable mounting structure for the wall decoration plates and the mounting method of the wall decoration plates aim at solving the technical problem that the distance between a wall body and the decoration plates is fixed due to the fact that a connecting piece between the decoration plates and the wall body is generally fixed in length, and when the wall surface is uneven, accordingly, the surfaces of the decoration plates are also uneven. The adjustable mounting structure comprises mounting plates used for being arranged on the wall body and the decoration plates arranged on the mounting plates, wherein the wall body is provided with the mounting plates, the mounting plates are provided with mounting rods, and adjusting rods are in threaded connection with the interiors of the mountingrods; and sliding blocks are arranged at the ends, away from the mounting rods, of the adjusting rods, sliding grooves allowing the sliding blocks to be inserted therein are formed in the surfaces ofthe sides, facing the sliding blocks, of the decoration plates, and the adjusting rods are provided with positioning assemblies in a sleeved mode. The adjustable mounting structure for the wall decoration plates and the mounting method of the wall decoration plates have the advantages that the distance between the decoration plates and the wall body can be adjusted conveniently so that the surfaces of the decoration plates can be even, and therefore, the decoration plate mounting quality is improved.

The invention relates to a tile multifunctional display seat. The tile multifunctional display seat includes a base, two supporting plates, U-shaped adjustment plates, and tile fixing plates; a plurality of side-by-side adjustment plates which are distributed longitudinally from front to back are arranged between the two supporting plates; the adjustment plates sleeve rotation shafts horizontallyand rotatably through rotatable sleeves; linkage assemblies are rotatably connected between adjacent adjustment plates so as to achieve synchronous rotation; angle fixing devices for fixing the rotation angle of the adjustment plates are arranged on the two adjustment plates at the left side and the right side; sliding rails corresponding to the tile fixing plates are arranged on the adjustment plates; a plurality of access channels are formed in the supporting plates at two ends; side walls at two sides of the access channels and the sliding rails extend outward to T-shaped clamping guiding grooves which are longitudinally distributed; and when the adjustment plates rotate to a vertical state, the access channels at the two sides and the sliding rails corresponding to the adjustment plates are located in the same plane and mutually communicate with each other. The tile multifunctional display seat facilitates storage of tiles, and can help clients to watch and select tile samples.
