[0001] This utility model provides a municipal manhole cover, belonging to the field of municipal equipment technology, and particularly relates to a municipal manhole cover that regulates drainage volume. Background Technology

[0002] Municipal manhole covers play a vital role in drainage. As an essential component of the sewer system, they facilitate the flow of surface water into the drainage system, preventing road flooding and ensuring the smooth operation of the urban drainage system. Urban drainage systems typically incorporate facilities for separating sewage and rainwater. During periods of excessive rainfall, rainwater flows through storm drains to the sewer system containing the manhole cover and is quickly drained away, preventing potential flooding and blockages. Furthermore, municipal manhole covers prevent debris and pollutants from entering the sewer system, protecting the operational safety of facilities and maintaining environmental hygiene. In urban management, the maintenance and management of municipal manhole covers should be prioritized to ensure their normal operation and effective functioning.

[0003] The existing municipal manhole cover structure is too simple, making it difficult to achieve timely and effective drainage in the face of heavy rainfall. If the drainage hole is set too large, it may pose a safety hazard during daily use, leading to casualties. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, this application provides a municipal manhole cover that can adjust the drainage volume, thus solving the problems of poor flexibility of existing municipal manhole covers, which cannot be adjusted according to the required drainage volume to adapt to drainage and prevent floods.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a municipal manhole cover for adjusting drainage volume, including a manhole cover, a support platform provided below the manhole cover, a gear ring located below the manhole cover inside the support platform, a water inlet corresponding to the adjustment plate and penetrating the manhole cover connected above the gear ring via an adjustment plate, and inclined water troughs symmetrically distributed on both sides of the gear ring inside the support platform.

[0006] Preferably, the manhole cover has an inlet channel inside that is placed around the inlet and passes through the manhole cover. One end of the channel near the inlet channel has a connecting channel that is connected to the channel and corresponds to the inlet channel.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] It should be noted that the terms "vertical," "horizontal," "up," "down," "left," "right," and similar expressions used in this article are for illustrative purposes only and do not represent the only possible implementation.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0026] As shown in Figures 1 and 2, the present invention provides a municipal manhole cover for adjusting drainage volume, including a manhole cover 1, a support platform 11 located below the manhole cover 1, and a water inlet trough 13 located inside the manhole cover 1, which is placed around the water inlet 12 and penetrates the manhole cover 1. A water trough 22 has a connecting groove 14 at one end near the water inlet trough 13, which is connected to the water trough 22 and corresponds to the water inlet trough 13. The other end of the water trough 22 is connected to a water outlet 111 that penetrates the support platform 11 and is connected to the water trough 22. A gear ring 2 located below the manhole cover 1 is located inside the support platform 11. The water inlet 12 corresponding to the adjustment plate 21 and penetrating the manhole cover 1 is connected above the gear ring 2 through an adjustment plate 21. Inclined water troughs 22 are symmetrically distributed on both sides of the gear ring 2 inside the support platform 11.

[0027] In this embodiment, by setting a manhole cover 1 body with a water inlet 12, when the drainage enters the water tank 22 in the support platform 11, the tilt of the water tank 22 washes the gear ring 2, causing the gear ring 2 to rotate, thereby aligning the adjusting plate 21 with the water inlet 12, so that the water inlet 12 connects to the water tank, increasing the drainage volume.

[0028] As shown in Figures 3 and 4, the regulating plate 21 is provided with an regulating hole 23 that passes through the regulating plate 21 and corresponds to the water inlet 12. The support platform 11 is provided with a storage groove 15 that accommodates the gear ring 2 and the regulating plate 21. The bottom end of the storage groove 15 and the water tank 22 are connected to the water outlet 111. A spring 16 is provided in the storage groove 15 and placed on one side of the regulating plate 21. One end of the spring 16 is connected to a clamping plate 17 that is fixedly connected to the side of the water tank 22. The other end of the spring 16 is connected to the regulating plate 21. The width of the clamping plate 17 is the same as the distance between the inner wall of the storage groove 15 and the side wall of the regulating plate 21.

[0029] In this embodiment, when rainwater enters the water tank 22 from the water inlet 13 on the manhole cover 1 through the connecting groove 14, the water tank 22 is centrally symmetrically distributed, which can drive the gear ring 2 to rotate. As the water flow increases, the flow speed increases, which in turn can squeeze the spring 16. The gear ring 2 drives the adjusting plate 21 to rotate, so that the adjusting hole 23 is aligned with the water inlet 12. The greater the water flow, the larger the overlapping part of the water inlet 12 and the adjusting hole 23 becomes. The clamping plate 17 can prevent excessive displacement.

[0030] It should be noted that this utility model provides a manhole cover 1 and an attached adjustment structure. For specific installation methods with sewers, please refer to existing manhole cover installation methods. This article will not elaborate on or limit these methods.

[0031] During use, installation is as follows: First, install the municipal manhole cover that adjusts drainage volume at the corresponding position in the underground pipeline system, and fix and connect it according to the existing manhole cover installation method; Water inlet and drainage: When rainwater or sewage enters the inlet 12 of the manhole cover, the water flow will enter the water tank 22 through the inlet trough 13 and the connecting trough 14. According to the design described, with the help of the inclination and central symmetry distribution of the water tank 22, the water flow can drive the gear ring 2 to rotate, so that the adjusting plate 21 can automatically align with the inlet 12, increasing the drainage volume; Automatic adjustment: The rotation of the gear ring 2 aligns the adjusting plate 21 with the inlet 12, so that the water tank The area of ​​the connecting section between the manhole cover and the inlet gradually increases. As the water flow increases, the regulating plate 21 automatically adjusts according to the change in water flow to maintain a suitable drainage volume. The spring and clamping plate also play a role: The description also mentions the design of spring 16 and clamping plate 17, which also function when the water flow increases. For example, the compression of spring 16 drives the rotation of gear ring 2 and regulating plate 21, and clamping plate 17 limits excessive displacement, maintaining stable drainage regulation. Finally, regular inspection and maintenance of the municipal manhole cover and its regulating structure are necessary to ensure its normal operation and effective drainage. In summary, using this municipal manhole cover for drainage regulation mainly involves installation and automatic drainage adjustment. Its design structure can automatically adjust according to changes in water flow, ensuring the smooth flow and efficiency of the drainage system.
