The utility model provides a communication base station, and relates to the technical field of communication base stations. The device comprises a base and a supporting tower, the windproof mechanism comprises a supporting frame and a first supporting rod, the two ends of the first supporting rod are installed on the bottom face and the end face of the supporting frame respectively, a second servo motor is fixedly installed on one side of the supporting frame, and a second supporting column is fixedly installed between the bottom face and the end face of the supporting frame. Connecting rods are hinged to the two ends of the sliding rod correspondingly, and wind blocking blocks are hinged to the two ends of the second supporting column correspondingly. In the working process of the device, wind can be effectively guided to the two sides by adding the windproof mechanism and the connecting rods to support the wind blocking block, the wind resistance of the device is enhanced, and therefore the potential risk that the wind blocking block is scraped by wind to deform is increased, and the problem that the wind blocking block deforms when faced with strong natural wind is solved. If the air deflector lacks enough support, the risk that the air deflector is scraped by wind power to deform exists, and once the air deflector deforms, the air deflector possibly collides with a base station antenna.

The invention relates to the technical field of protective devices, in particular to a protective device for grassland pest control, comprising: two groups of upper cylinders which are rotatably connected and can surround a circular structure to protect plants; a clamping assembly is arranged in a placement cavity formed in the upper cylinder, the clamping assembly comprises a clamping piece arranged in the upper cylinder, and a trigger piece and an encircling structure are arranged on the clamping piece; the device further comprises a driving assembly arranged on the upper cylinders, the driving assembly comprises driving parts slidably arranged on the upper cylinders, after the two upper cylinders surround a circular structure, the driving parts are driven to slide along the relative upper cylinders, the driving parts can drive the clamping parts to get close to the axes of the upper cylinders, and in the approaching process, the triggering parts make contact with plants firstly, and then the triggering parts make contact with the plants. Then, under the cooperation of the plant, the triggering piece can drive the surrounding structure to act, so that the plant is protected in a surrounding mode, then the climbing path of the mouse can be cut off, and the mouse is prevented from gnawing the fruit of the plant.

The utility model relates to the technical field of breeding escape-proof devices, in particular to a hairy crab breeding escape-proof device which comprises a foundation, an L-shaped installation plate is arranged on the upper portion of the foundation and installed in an inverted mode, the long edge of the L-shaped installation plate is attached to the water facing edge of the foundation, and the short edge of the L-shaped installation plate is connected with the top of the foundation through a fixing pin. The L-shaped mounting plate is provided with a portable mounting anti-escape assembly, the portable mounting anti-escape assembly is used for preventing the hairy crabs in the breeding pond from escaping, and the anti-escape device for breeding the hairy crabs aims at solving the problems that an existing anti-escape structure is inconvenient to mount and not ideal in anti-escape effect.

The utility model relates to a power transmission tower belongs to the electric power facility safety protection technical field, concretely is a kind of power transmission tower with anti-climbing structure, including electric tower main body, mounting bracket, main protection baffle, rotating shaft mechanism, safety control cabinet and vice protection baffle. Mounting bracket is connected by fixed assembly, rotating shaft mechanism can adjust the inclination angle of main protection baffle, and main vice protection baffle encloses anti-climbing structure. Safety control cabinet is equipped with door lock component, and main protection baffle bottom is opened with flow guide groove. The utility model reached the effect that flexible adjustment anti-climbing angle, enhance protection effect, prevent misoperation, avoid rainwater erosion, solved the existing power transmission tower anti-climbing structure angle fixed, protection effect is not good, easily be adjusted and damaged due to rainwater erosion etc. problem, effectively guarantee power transmission tower operation safety.
