The utility model discloses a kind of pest control devices, including shell, the bottom of the shell is fixedly connected with mounting plate, the bottom of the mounting plate is fixedly connected with quartz glass cover, the bottom of the mounting plate is fixedly embedded with black light, the bottom of the mounting plate is fixedly connected with multiple metal rods, the bottom of multiple metal rods is fixedly connected with same conical base plate, the bottom outer wall of the conical base plate is threadedly sleeved with annular ring, annular groove is arranged in the bottom of the annular ring.The utility model can drive rubber scraping strip to clean the inner wall of conical base plate by rotating insect-collecting plastic bottle, avoid rough contact surface caused by accumulation to make pest crawl away, ensure that subsequent pest enters insect-collecting plastic bottle smoothly, improve the success rate of trapping, and cleaning the inner wall of conical base plate without disassembling device, can be completed cleaning without affecting the use of insect-collecting plastic bottle, easy to operate, ensure the continuity of trapping operation.

This invention relates to the field of linear sliding drive structure technology, specifically a sliding mechanism for laser cutting and grooving of connecting rods. It includes a profile rod, a guide rack, and a harmonic moving assembly. The guide rack is fixedly mounted on one side of the profile rod, and the harmonic moving assembly is arranged on the upper and lower sides relative to the guide rack and is driven to rotate by a drive assembly. The harmonic moving assembly includes a main shaft and several moving sleeve blocks axially sleeved on the surface of the main shaft. An eccentric collar is provided on the surface of the main shaft, and the eccentric collar cooperates with the moving sleeve blocks through a shaft slip ring, causing the moving sleeve blocks to periodically engage and disengage relative to the surface of the guide rack during the rotation of the main shaft. The symmetrically arranged harmonic moving assembly achieves symmetrical force distribution on the guide rack, and the alternating advancement of the multiple moving sleeve blocks effectively reduces thrust pulsation and improves low-speed operation stability. This invention is applicable to laser cutting sliding applications involving long strokes, low speeds, high thrust, and multi-axis linkage.

The utility model discloses an iron clamp type sleeper anti-creeping device which comprises rail clamps and a control box, the number of the rail clamps is two, installation grooves are formed in the middles of the interiors of the two rail clamps, and nuts are welded to the interiors of the installation grooves. By the adoption of the pressure sensor, the ratchet wheel and the motor, when the device is used, the rail clamp is certainly driven to move due to vibration and rotation of the fastening bolt, then the extrusion force between the rail and the rail clamp is changed, the pressure value detected by the pressure sensor is reduced at the moment, and at the moment, the rail clamp is driven to move. The driving shaft can be driven to rotate through operation of the motor, then the coupler is driven to rotate through the ratchet wheel, and then the butt joint rod is driven to rotate, so that the fastening bolt is driven, the rail clamp is fastened again, a sleeper is prevented from crawling, and the use stability and the use strength of the structure are guaranteed; the device has the advantages of looseness detection and looseness fastening.

This invention belongs to the field of autonomous underwater vehicle (AUV) recovery technology, specifically disclosing a side-thrust recovery method and apparatus for AUVs. The recovery method includes the following steps: Step 1, the mother ship releases a recovery boat with a cable to the water surface and controls the recovery boat to move towards the AUV; Step 2, when the distance between the recovery boat and the AUV reaches a set distance, the position of the recovery boat is adjusted, and then the mechanical claw at the front of the recovery boat grabs the AUV from the side; Step 3, the mother ship retrieves the cable, and the cable drives the recovery boat and the AUV to move to the mother ship; This invention provides a side-thrust recovery method and apparatus for AUVs that can flexibly, efficiently, and safely recover AUVs.
