Description

Technical Field

[0001] The utility model relates to the field of municipal engineering, and more specifically, to a drainage manhole cover for urban road construction. Background Art

[0002] With the acceleration of urbanization, urban road construction is becoming increasingly important. As an important part of the urban road drainage system, the design and function of the drainage manhole cover are directly related to the urban drainage efficiency and road safety. The traditional drainage manhole cover is simple in design, usually just a cover with holes. Although this design can achieve basic drainage functions, it has obvious shortcomings in preventing blockage and improving drainage efficiency. Therefore, developing a new type of drainage manhole cover for urban road construction to solve the above problems has become an important research direction in the current field of urban road construction. Utility Model Content

[0003] 1. Technical issues to be solved

[0004] The traditional drainage manhole cover in the prior art is simple in design and is usually just a cover plate with holes. Although this design can achieve basic drainage functions, it is obviously insufficient in preventing blockage and improving drainage efficiency. The purpose of the utility model is to provide a drainage manhole cover for urban road construction, which can effectively prevent large debris from entering the drainage system by setting a filter net and a supporting device, reduce the risk of blockage, and improve drainage efficiency. At the same time, the supporting device can block the filter net to reduce the entry of debris at ordinary times. The anti-slip texture or convex design on the surface of the cover body increases the friction coefficient, effectively preventing pedestrians or vehicles from slipping on the surface of the manhole cover, and improving the safety of road use. At the same time, a drainage device is arranged under the cover body. When the drainage is too large and the rainwater entering through the through hole is greater than the rainwater discharged from the drain port, the weight of the collection frame increases, driving the support device to work, thereby removing the blocking of the filter net and increasing the drainage efficiency. When the rainwater decreases, the support device automatically resets, making cleaning and maintenance more convenient and reducing maintenance costs.

[0013] 3. Beneficial effects

[0014] Compared with the prior art, the advantages of the present invention are:

[0015] By setting up a filter net and a support device, large pieces of debris can be effectively prevented from entering the drainage system, reducing the risk of blockage and improving drainage efficiency. At the same time, the support device can cover the filter net to reduce the entry of debris at ordinary times.

[0016] The anti-slip patterns or raised designs on the surface of the cover increase the friction coefficient, effectively preventing pedestrians or vehicles from slipping on the surface of the manhole cover and improving the safety of road use.

[0023] Embodiment 1:

[0024] See also Figure 1-3 The utility model provides a technical solution: a drainage manhole cover for urban road construction, including a cover body 1, a tray 2 is sleeved on the outside of the cover body 1, the tray 2 is fixedly connected to the road surface, through holes 3 are arranged at equal angles on the surface of the cover body 1, a filter screen 4 is arranged in the middle of the cover body 1, a supporting device 5 is arranged below the filter screen 4, the supporting device 5 blocks the filter screen 4, a drainage device 6 is arranged below the through hole 3, and the drainage device 6 is connected to the supporting device 5. The cover body 1 is provided with a through hole 3 for drainage of small flow rate. The filter screen 4 and the supporting device 5 effectively prevent large debris from entering the drainage system, reduce the risk of blockage, and improve the drainage efficiency. At the same time, the supporting device 5 can block the filter screen 4 to reduce the entry of debris at ordinary times. At the same time, a drainage device 6 is arranged under the cover body 1. When the drainage is too large, the rainwater entering through the through hole 3 is greater than the rainwater discharged from the drain port 63 of the collecting frame 61, the weight of the collecting frame 61 increases, driving the supporting device 5 to work, thereby removing the blocking of the filter screen 4 and increasing the drainage efficiency. When the rainwater decreases, the supporting device 5 is automatically reset, making cleaning and maintenance more convenient and reducing the maintenance cost.

[0025] Among them, the supporting device 5 includes a fixed rod 51, a fixed block 52, a baffle 53, a spring 54, a moving rod 55 and a connecting frame 56. The fixed rod 51 is fixedly connected to the bottom of the filter screen 4, the bottom of the fixed rod 51 is fixedly connected to the fixed block 52, the fixed rod 51 is slidably connected to the baffle 53, the baffle 53 blocks the filter screen 4, the bottom of the baffle 53 is fixedly connected to the spring 54, the spring 54 is sleeved with the fixed rod 51, the bottom of the spring 54 is connected to the fixed block 52, the middle bottom of the baffle 53 is fixedly connected to the moving rod 55, the bottom of the moving rod 55 is fixedly connected to the connecting frame 56, and the connecting frame 56 is connected to the drainage device 6. A supporting device 5 is provided, and a fixed block 52 supports a baffle 53 through a spring 54, so that the baffle 53 blocks the filter screen 4, thereby reducing the entry of debris. When the rain is too heavy, the drainage device 6 drives the baffle 53 to move downward, increases the elastic potential energy of the spring 54, releases the blocking of the filter screen 4, exposes the filter screen 4, and increases the drainage volume.

[0026] There are two fixing rods 51 to improve the movement stability of the baffle 53.

[0027] The drainage device 6 includes a collection frame 61, a protective net 62 and a drainage port 63. The collection frame 61 is located below the through hole 3.

The outer wall of the collection frame 61 is fixedly connected to the connecting frame 56. The drainage device 6 is provided. The collection frame 61 collects the water flowing into the through hole 3 and discharges it through the drainage port 63. When the collected rainwater is greater than the rainwater discharged from the drainage port 63, the weight of the collection frame 61 increases, driving the connecting frame 56 to move downward, and then driving the baffle 53 to move downward, thereby removing the shielding of the filter 4.

[0028] The protective net 62 is arched, which is convenient for intercepting and filtering the incoming sewage.

[0029] The surface of the cover 1 is provided with anti-skid patterns or protrusions to prevent pedestrians or vehicles from slipping on the surface.
