[0025] EMBODIMENT

[0026] Please refer to Figs. 1-3 The utility model discloses a wellhead protection device, including setting up in the protection pier 100 of ventilation well mouth and the isolation net 200 of detachable installation in the side surface of protection pier 100;

[0027] The protection pier 100 includes the pier body 101 of built-in ventilation passage, the inclined roof 102 of integral setting in the top of pier body 101, the frame 103 of embedding in the side surface of pier body 101 and the ventilation grille 104 of fixing in the inside of frame 103, the side surface of pier body 101 is surrounded and is provided with magnetic attraction groove 101b, pier body 101 is usually made of concrete, and the built-in ventilation passage guarantees the air circulation, and simultaneously provides the installation foundation for other structures, and the magnetic attraction groove 101b that is surrounded and is provided in the side surface of pier body 101 is used to cooperate with the magnetic attraction strip 202 on the isolation net 200, so that the isolation net 200 can be quickly and stably fixed on the protection pier 100;

[0028] The isolation net 200 includes the magnetic attraction strip 202 matched with magnetic attraction groove 101b and the screen 201 fixed to the outside of magnetic attraction strip 202, and the magnetic attraction strip 202 is adsorbed in the magnetic attraction groove 101b of pier body 101 through magnetic force, realizes the quick installation and dismounting of isolation net 200, and this tool-free installation mode greatly facilitates the routine maintenance work, but the adsorption strength of magnetic attraction strip 202 needs to satisfy certain standards to ensure that the isolation net 200 will not easily fall off under the action of strong wind or other external force.

[0029] Specifically, the ventilation grille 104 is composed of multiple inclined downward baffles, which helps to block rainwater while maintaining good ventilation performance, and the ventilation grille 104 forms a ventilation system with the built-in ventilation passage of the pier body 101, the screen 201 is located outside the ventilation grille 104, and the screen 201 is uniformly distributed with micro-holes, the magnetic attraction strip 202 is fixed to the inside edge of the screen 201, the screen 201 is a plastic product, and the screen 201 is made of plastic products, which has the characteristics of light weight, low cost, corrosion resistance, etc., and the micro-holes do not affect ventilation and can effectively prevent larger objects from entering.

[0030] Furthermore, the two ends of the pier 101 are recessed inward to form warning areas 101a, which are sprayed with warning signs. The recessed warning areas 101a are painted with eye-catching warning signs, such as yellow or red paint, which can serve as a clear warning both day and night, reminding pedestrians to pay attention to safety. The top of the sloping roof 102 is provided with strip grooves at equal intervals, and the edge of the sloping roof 102 extends outward to form a rainproof edge 102a. The strip grooves at equal intervals on the top of the sloping roof 102 not only reduce the structural weight but also increase the aesthetics.
