Abstract
Description
Technical Field
[0001] This utility model relates to the field of municipal technology, and in particular to a mosquito-proof plug for a manhole cover and its installation structure. Background Technology
[0002] Manhole covers, as an important part of urban infrastructure, often become breeding grounds for mosquitoes due to design flaws. While traditional manhole covers effectively reduce noise from vehicles, the presence of pry holes provides mosquitoes with ideal breeding channels. These circular holes, about 2-3 centimeters in diameter, facilitate tool access for maintenance personnel and create a humid microenvironment due to long-term exposure. The decomposition of organic matter accumulated inside the manhole produces carbon dioxide and heat, attracting female mosquitoes to lay eggs. The hatched mosquitoes, flying out of the manhole holes, can directly transmit diseases such as dengue fever and Japanese encephalitis, with a range of activity up to 500 meters, forming a potential epidemic zone centered on the manhole cover. Furthermore, mosquito larvae breed in the stagnant sewage accumulated in the manholes. This water often contains heavy metals and organic pollutants, significantly increasing the probability that mosquitoes carry pathogens.
[0003] Therefore, there is an urgent need to design a mosquito plug that can cover the pry hole of the manhole cover. Utility Model Content
[0004] The purpose of this invention is to provide a mosquito-proof plug for manhole covers, which is installed on the pry holes of manhole covers to prevent mosquitoes from flying out or to prevent mosquitoes from flying in and laying eggs.

The fastening parts deform during the process of passing through the pry hole of the manhole cover, and the fastening parts restore their deformation and fasten to the lower surface of the manhole cover after passing through the pry hole of the manhole cover.
[0006] By adopting the above technical solution, the covering part is used to cover the pry hole of the manhole cover, and the fastening part is used to fasten and fix it on the lower surface of the manhole cover to prevent the mosquito plug from falling off after installation. Finally, it is used to install on the pry hole of the manhole cover to prevent mosquitoes from flying out or to prevent mosquitoes from flying in and laying eggs.
[0007] A further feature of this invention is that the covering part, the connecting part, and the fastening part are integrally formed, and the covering part, the connecting part, and the fastening part are all made of rubber material.
[0008] By adopting the above technical solution, the covering part, connecting part and fastening part are all supported by an integral rubber material, so that pedestrians or vehicles are less likely to make abnormal noises after passing through the mosquito plug, and the deformation function of the fastening part is satisfied to achieve fastening installation.
[0009] A further feature of this invention is that the plurality of fastening portions are arranged in a circumferential array, and the sides of the fastening portions extend downward at an angle toward the connecting portion.
[0010] By adopting the above technical solution, the side of the fastening part extends downwards towards the direction of the connecting part, so as to guide the fastening part through the pry hole of the manhole cover.
[0011] The lower surface of the cover is provided with an adhesive layer surrounding the connector, and a tearable release layer is provided on the adhesive layer.
[0012] By adopting the above technical solution, after the release layer is torn off, the adhesive layer can be bonded to the upper surface of the manhole cover, further fixing the cover and increasing the stability of the mosquito plug after installation.
[0013] The purpose of this utility model is to provide an installation structure for a mosquito-proof plug for a manhole cover, which is used to install on the pry hole of the manhole cover to prevent mosquitoes from flying out or to prevent mosquitoes from flying in and laying eggs.
[0014] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an installation structure for a mosquito plug on a manhole cover, comprising a manhole cover with a pry hole and a mosquito plug, wherein the covering part of the mosquito plug abuts against the upper surface of the manhole cover and covers the pry hole, the connecting part of the mosquito plug passes through the pry hole, and the fastening part of the mosquito plug passes through the pry hole and fastens to the lower surface of the manhole cover.
[0015] By adopting the above technical solution, mosquito plugs can be installed in the pry holes of manhole covers to prevent mosquitoes from flying out or from flying in and laying eggs.
[0016] The purpose of this utility model is to provide an installation structure for a mosquito-proof plug for a manhole cover, which is used to install on the pry hole of the manhole cover to prevent mosquitoes from flying out or to prevent mosquitoes from flying in and laying eggs.
[0017] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an installation structure for a mosquito-proof plug for a manhole cover, comprising a manhole cover with a pry hole and a mosquito-proof plug, wherein the covering part of the mosquito-proof plug abuts against the upper surface of the manhole cover and covers the pry hole, the connecting part of the mosquito-proof plug passes through the pry hole, and the fastening part of the mosquito-proof plug passes through the pry hole and fastens to the lower surface of the manhole cover, and the release layer is torn open to allow the adhesive layer to adhere to the upper surface of the manhole cover.

[0029] Implementation effect: After the release layer 15 is torn off, the adhesive layer 14 can be bonded to the upper surface of the manhole cover, further fixing the cover part 11 and increasing the stability of the mosquito plug after installation.
[0030] Example 3: An installation structure for a mosquito-proof plug on a manhole cover, such as... Figure 1 and Figure 3 As shown, the manhole cover 2 with a pry hole 21 and a mosquito plug are included. The covering part 11 of the mosquito plug abuts against the upper surface of the manhole cover 2 and covers the pry hole 21. The connecting part 12 of the mosquito plug passes through the pry hole 21. The fastening part 13 of the mosquito plug passes through the pry hole 21 and fastens to the lower surface of the manhole cover 2.
[0031] Implementation effect: The mosquito plug is installed in the pry hole 21 of the manhole cover 2, thereby preventing mosquitoes from flying out or from flying in and laying eggs.
[0032] Example 4: An installation structure for a mosquito-proof plug on a manhole cover, such as... Figure 2 and Figure 4 As shown, the manhole cover 2 includes a pry hole 21 and a mosquito plug. The covering part 11 of the mosquito plug abuts against the upper surface of the manhole cover 2 and covers the pry hole 21. The connecting part 12 of the mosquito plug passes through the pry hole 21. The fastening part 13 of the mosquito plug passes through the pry hole 21 and fastens to the lower surface of the manhole cover 2. After the release layer 15 is torn open, the adhesive layer 14 is bonded to the upper surface of the manhole cover 2.
[0033] Implementation effect: Based on the mosquito plug being installed in the pry hole 21 of the manhole cover 2, the stability of the mosquito plug after installation is improved by the adhesive layer 14.
