Description

Technical Field

[0001] The utility model relates to the technical field of municipal road drainage, and more particularly to a municipal road drainage structure. Background Art

[0002] There are some significant problems and limitations in the existing municipal road drainage structure technology, which not only affect the drainage effect, but also may lead to long-term maintenance difficulties and environmental problems.

[0003] First of all, in the existing technology, drainage boards and other devices are usually set up on both sides of the road to achieve timely drainage of the road. Although this method can achieve basic drainage functions to a certain extent, it has obvious defects in dealing with foreign objects and garbage of different sizes. In particular, for foreign objects of smaller sizes, the existing drainage board design is often unable to effectively intercept these small foreign objects, such as tiny leaf fragments, sand, plastic particles, etc., which can easily pass through the gaps in the drainage board and directly enter the drainage pipe below. These small foreign objects accumulate in the pipe, gradually forming a blockage, reducing drainage efficiency. What is more serious is that long-term blockage may cause corrosive substances to be produced inside the pipe, accelerate pipe aging, and even cause pipe rupture, which not only increases maintenance costs, but may also cause environmental problems such as groundwater pollution.

[0004] Secondly, in response to the above problems, some existing technologies attempt to use filter tanks to intercept smaller foreign objects and filter sewage. This method can theoretically effectively solve the problem of small foreign objects entering the pipeline, but in practical applications it faces new challenges. The installation process of the filter tank is usually cumbersome, involving multiple steps and complex operations. This cumbersomeness not only increases the installation time, but also increases the technical requirements of the operation. The cumbersome installation process brings many adverse effects. First, it prolongs the time for road maintenance. On busy urban roads, long maintenance operations may cause serious traffic congestion. Secondly, the complicated installation process increases the risk of operational errors. In addition, the cumbersome installation process also increases the workload of maintenance personnel, which may lead to a decrease in work efficiency and even affect work enthusiasm, indirectly affecting the maintenance quality of the entire drainage system.

[0005] Finally, in order to solve the problem of cumbersome installation of the filter bin, some equipment uses certain components to achieve quick installation of the filter bin. These solutions have simplified the installation process and improved efficiency to a certain extent. However, these improvements are mainly focused on the installation link, while ignoring the equally important disassembly process. Many designs require the use of specific tools to complete the disassembly. The use of these tools not only increases the complexity of the operation, but also prolongs the disassembly time. More importantly, this design that relies on specific tools increases maintenance costs because each maintenance team needs to be equipped with these special tools. In addition, the complicated disassembly process also increases the risk of damage to the filter bin or other related components. In an emergency, such as when a severely clogged filter bin needs to be quickly cleaned, the cumbersome disassembly process may delay the processing time and aggravate the drainage problem.

[0017] (3) Beneficial effects

[0018] Compared with the existing technology, this utility model provides a municipal road drainage structure with the following features:

[0019] Beneficial effects:

[0020] 1. The beneficial effect of the filtration device is that it solves the problem of small foreign objects directly entering the pipe and causing blockage in the existing technology.

[0022] 3. The beneficial effect of the quick-release mechanism is that it solves the problem in the prior art that the disassembly of the filter bin is complicated and requires special tools. By designing a quick-release system including components such as a connecting plate, an inclined block, an inclined groove, a spiral groove, a sleeve and a spiral block, the filter bin can be quickly disassembled. This design not only simplifies the disassembly process, but also eliminates the dependence on special tools. It greatly reduces the disassembly time and reduces maintenance costs. It also reduces the risk of damaging the filter bin or other components during the disassembly process. Especially when a severely clogged filter bin needs to be urgently cleaned, the quick-release mechanism can significantly shorten the processing time and effectively prevent the aggravation of drainage problems. In addition, this design also improves the convenience of daily maintenance, encourages more frequent and timely maintenance, and further improves the long-term performance and reliability of the entire drainage system.
