In addition, the technical features involved in each embodiment of the utility model described below can be combined with each other as long as they do not conflict with each other.

[0038] like Figures 1 to 5 As shown, in the embodiment of the utility model, the auxiliary device for preventing rats and mosquitoes for outdoor rainwater wells includes:

[0039] A mosquito-proof auxiliary cover unit 2 installed in the manhole cover installation groove 500 of the rainwater well 5, a rat-proof cover installation groove 300 opened on the mosquito-proof auxiliary cover unit 2, a rat-proof auxiliary cover 3 installed in the rat-proof cover installation groove 300, and a poison bait automatic delivery unit 4 fixedly connected to the mosquito-proof auxiliary cover unit 2;

[0040] The mosquito-proof auxiliary cover unit 2 includes a cover base 200, a top edge mounting edge 210 extending around the cover base 200 and mounted on the manhole cover mounting groove 500, and a closed-door mosquito-proof component 220 disposed on the bottom of the cover base 200;

[0041] The auxiliary rodent-proof cover 3 is a porous shell structure;

[0042] The poison bait automatic delivery unit 4 comprises a poison bait storage bin 400 opened in the cover base 200 and a poison bait delivery assembly 410 disposed below the poison bait storage bin 400 ; a bait delivery channel 402 is disposed below the poison bait storage bin 400 , and the bait delivery channel 402 is in continuous communication with the poison bait delivery assembly 410 .

[0043] In the embodiment of the utility model, a closed-door anti-mosquito auxiliary cover unit and an automatic poison bait delivery unit are added on the basis of the traditional mesh rat-proof cover. On the one hand, the entry and exit of small mosquitoes and insects at the rainwater well mouth are cut off, and the rat-proof auxiliary cover also prevents rats from entering and exiting the rainwater well. On the other hand, the effective combination of the poison bait storage bin and the poison bait delivery component solves the technical problem that the traditional method has a small amount of poison bait and cannot achieve long-term rat and mosquito prevention.

[0044] like Figure 1 and Figure 2 As shown, in the embodiment of the utility model, the closed-door mosquito-proof assembly 220 includes:

[0045] A bottom mounting section 222 located at the lower layer of the cover base 200, an axial hole opened in the bottom mounting section 222, a rotating connecting shaft 223 installed in the axial hole, a mosquito-proof normally closed door 224 rotatably connected to the bottom mounting section 222 through the rotating connecting shaft 223, an end counterweight block 226 arranged on the outer side of the mosquito-proof normally closed door 224, and a normally closed door limit stopper 419 fixedly connected to the bottom mounting section 222;

[0046] The mosquito-proof normally closed door 224 is provided with a door body mounting groove 225 rotatably connected to the bottom mounting section 222 near the end.

[0047] The embodiment of the utility model adopts a rotatable mosquito-proof normally closed door. Under the action of the end counterweight block, the door remains in a normally closed state. However, when rainwater leaks, the mosquito-proof normally closed door will automatically open due to gravity, thereby achieving rainwater leakage.

[0048] like Figure 3 As shown, in the embodiment of the utility model, the poison bait feeding assembly 410 includes:

[0049] A vertical sliding groove 401 provided in the cover base 200, a poison bait drain pipe 412 sliding in the vertical sliding groove 401, a tube side bait hole 414 provided in the side wall of the poison bait drain pipe 412 near the vertical sliding groove 401, a top stopper 411 fixed on the top of the poison bait drain pipe 412, a spring-up spring 413 provided between the top stopper 411 and the bottom of the poison bait storage bin, a side limit stopper 418 fixed below the tube side bait hole 414 for limiting the spring-up amplitude thereof, a bottom poison bait storage box 416 hoisted below the lower end of the poison bait drain pipe 412, a poison bait thumbwheel 417 provided at the upper entrance of the bait drain channel 402, and a thumbwheel driving assembly 420 for driving the poison bait thumbwheel 417 to rotate by means of the vertical sliding of the poison bait drain pipe 412;

[0050] The vertical sliding groove 401 and the bait leakage channel 402 are connected.

[0051] In the embodiment of the utility model, by setting the leakage pipe of the poison bait as a sliding structure, when there are rodents at the bottom dragging and biting the poison bait, the leakage pipe of the poison bait is driven to slide down, so that the movement is converted into the rotation of the poison bait dial with the help of the dial drive component, thereby realizing the leakage and replenishment of the poison bait and achieving the effect of automatic bait delivery.

[0052] In addition, by changing the elastic force of the upward spring 413 and the relative height of the bait hole 414 on the tube side relative to the bait leakage channel 402, the automatic release of the poison bait can be realized by the downward movement of the poison bait leakage tube or the upward movement of the poison bait leakage tube. When the mosquito slow-release poison bait is used, a small elastic spring is used, and the poison bait leakage tube is pulled down under the action of the gravity of the poison bait. When the mass of the slow-release poison bait is reduced to a certain value, it can be regarded as insufficient poison bait, and the "poison bait leakage tube moves upward when the poison bait leakage tube" action can be used to realize the automatic release of the poison bait.

[0053] like Figure 4 and Figure 5 As shown, in the embodiment of the utility model, the thumbwheel driving assembly 420 includes:

[0054] A vertical driving rack 421 fixed above the top stopper 411, a transverse driving rack 423 that maintains orthogonal motion transmission with the vertical driving rack 421 through an intermediate transmission gear 422, a reciprocating slide member 424 fixedly connected to the lower right side of the transverse driving rack 423, and a guide slot 4240 opened on the side of the reciprocating slide member 424;

[0055] An end sliding rod 426 fixedly connected to the central rotating shaft of the poison bait wheel 417 via an intermediate connecting rod 425;

[0056] The end sliding rod 426 maintains a sliding connection with the guide sliding groove 4240 .

[0057] like Figure 3 As shown, in the embodiment of the utility model, a length adjustment rod 415 is provided between the bottom poison bait containing box 416 and the lower end of the poison bait lower leakage pipe 412, so as to realize the height adjustment of the bottom poison bait containing box 416.

[0058] It is worth noting that the bait drain pipe 412 can be configured as a retractable structure to meet the needs of preventing rats and mosquitoes in wells of different depths.

[0059] like Figure 4 As shown, in the embodiment of the utility model, the end sliding rod 426 is sleeved with a pulley, and the pulley is in sliding connection with the guide sliding groove 4240 .

[0060] like Figure 1As shown in Figure 2, in the embodiment of the utility model, the aperture of the auxiliary rodent-proof cover 3 is less than one centimeter.

[0061] It is worth noting that a moisture-proof and water-blocking cover can be provided at the opening of the poison bait storage bin 400 to prevent the poison bait and other drugs from being soaked by water. At the same time, a locking device can be used to set the moisture-proof and water-blocking cover to open and close to prevent other animals or children from opening and accidentally eating. At the same time, a warning slogan such as "Rat poison is toxic, please do not touch" can be added around the device, or the slogan can be printed or pasted on the box to improve the safety of the device.

[0062] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application shall be included in the protection scope of the present application. The above are only preferred implementations of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and variations can be made without departing from the technical principles of the present application, and these improvements and variations should also be regarded as the protection scope of the present application.
