Abstract
Description
Technical Field
[0001] The utility model relates to urban infrastructure, in particular to a drainage facility. Background Art
[0002] Big technical background: The urban sewer network is intricate and constitutes an important part of the urban drainage and flood control system, which is crucial to urban environmental sanitation and patriotic health. At the same time, sewers are also an important place for mosquitoes and rats to breed, which brings great prevention and control difficulties to urban patriotic health and prevention of vector-borne diseases. Sewer covers are the key to ensuring the effective operation of urban sewer networks. Ideal sewer covers should be low-cost and effectively prevent mosquitoes and rats from entering the sewers; prevent silt and garbage from entering the sewers, partially block the sewers to cause water accumulation, and reduce the breeding environment for mosquitoes and rats; at the same time, the components are not easy to lose and are anti-theft. At present, grid-type sewer covers are commonly used in cities. Although they are cheap, they have no anti-mosquito, anti-rat, anti-mud, and anti-theft functions, and the later operation and maintenance costs are high. With the high-quality development of society, it is necessary to design and update sewer covers to achieve functions such as mosquito prevention, rat prevention, mud prevention, and theft prevention. The cost is controllable, which can reduce the chances of mosquitoes and rats breeding in urban sewers, effectively retain silt and garbage, and facilitate the cleaning of silt and garbage, reducing the later operation and maintenance costs of urban sewer network systems.
[0003] A little technical background: With the high-quality development of society, it is necessary to design and update sewer covers to achieve functions such as anti-mosquito, anti-rat, anti-mud, and anti-theft. The cost is controllable, which can reduce the chances of mosquitoes and rats breeding in urban sewers, effectively retain silt and garbage, and facilitate the cleaning of silt and garbage, reducing the later operation and maintenance costs of urban sewer network systems. Utility Model Content
[0004] The technical problem solved by the utility model is that the existing sewer cover is too simple, mosquitoes and rats are easy to breed in the urban sewer network, and ground sludge and garbage are easy to accumulate in the sewer, causing the sewer to be blocked.
[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a mosquito-proof, rat-proof, mud-proof and theft-proof sewer cover, comprising a sewer cover base, and a sewer cover and a mosquito-proof, rat-proof and mud-proof gate installed on the sewer base, the mosquito-proof, rat-proof and mud-proof gate being located below the sewer cover, the mosquito-proof, rat-proof and mud-proof gate being formed with an obtuse-angled triangle cavity, the obtuse angle of the obtuse-angled triangle cavity and a first acute angle being located above while the second acute angle is located below, a filter plate is arranged on the inclined surface between the obtuse angle and the second acute angle, a side wing plate is hinged at the obtuse angle, and the side wing plate can cover the entire inclined surface between the obtuse angle and the second acute angle under the action of gravity.
[0006] The base of the sewer cover is fixed at the sewer outlet, and rainwater enters the obtuse triangle cavity of the mosquito, rat and mud gate through the sewer cover. Rainwater is concentrated at the second acute angle, passes through the filter plate and exits the obtuse triangle cavity, breaks through the side wing plate and enters the sewer, and silt and garbage are blocked in the obtuse triangle cavity. If the amount of rainwater is large, the rainwater can pass over the filter plate and enter the sewer through the water discharge gap above the filter plate.
[0007] When there is no rain, the side wing plates cover the entire slope between the obtuse angle and the second acute angle under the action of gravity, including the filter plate and the drainage gap above the filter plate. In this way, rats and mosquitoes can be prevented from entering the sewer from the ground, and rats and mosquitoes can also be prevented from entering the ground from the sewer.
[0008] The base of the sewer cover is provided with a mosquito-proof, rat-proof and mud-proof gate slot, and the mosquito-proof, rat-proof and mud-proof gate is provided with supporting side edges that cooperate with the mosquito-proof, rat-proof and mud-proof gate slot around the periphery, and the supporting side edges at the first acute angle of the obtuse triangle cavity are provided with a first rotating shaft, and the first rotating shaft is installed on the base of the sewer cover. The base of the sewer cover is provided with a hinged ear that cooperates with the first rotating shaft. Through the first rotating shaft, the mosquito-proof, rat-proof and mud-proof gate can be turned upward to dump the silt and garbage in the obtuse triangle cavity. Since the mosquito-proof, rat-proof and mud-proof gate is hinged to the base of the sewer cover, the mosquito-proof, rat-proof and mud-proof gate has an anti-theft function.
[0009] The anti-mosquito, anti-rat and anti-mud gate comprises a trapezoidal bottom plate and a trapezoidal side plate arranged in the front and rear, and a pair of inclined side plates arranged in the left and right. Compared with the rear side of the trapezoidal bottom plate, the front side of the trapezoidal bottom plate is at a high position and is connected to the supporting side, and the left and right sides of the trapezoidal bottom plate are respectively connected to a pair of inclined side plates. Compared with the front side of the trapezoidal side plate, the rear side of the trapezoidal side plate is at a high position and is connected to the supporting side, and the left and right sides of the trapezoidal side plate are respectively connected to a pair of inclined side plates. The front side of the trapezoidal side plate is located in the front upper part of the rear side of the trapezoidal bottom plate, and the front side of the trapezoidal side plate, the rear side of the trapezoidal bottom plate, and a pair of inclined side plates constitute a water discharge gap, which is the inclined surface between the obtuse angle and the second acute angle of the obtuse triangle cavity, and the filter plate is arranged on the water discharge gap, and the side wing plate is hinged on the front side of the trapezoidal side plate.
[0010] Since the front side of the trapezoidal side plate is located above and in front of the rear side of the trapezoidal bottom plate, and the side wing plate is hinged on the front side of the trapezoidal side plate, the side wing plate is inclined and covers the water discharge gap (i.e., the inclined surface between the obtuse angle and the second acute angle of the obtuse triangle cavity) under the action of gravity to close the mosquito, rat and mud gate. In order to enable the side wing plate to effectively close the water discharge gap, a counterweight is provided at the bottom of the side wing plate.
[0011] A handle is provided on the front side of the trapezoidal side plate, which is convenient for the operator to flip up the mosquito-proof, rat-proof and mud-proof gate.
[0012] The sewer cover adopts a grille design to facilitate the passage of rainwater. One side of the sewer cover is hinged to the sewer cover base through the third rotating shaft, which can play an anti-theft role. The third rotating shaft and the first rotating shaft are respectively located on opposite sides of the sewer cover base, so that the direction in which the sewer cover flips upward is opposite to the direction in which the mosquito, rat and mud gate flips upward. The two are open to facilitate the mosquito, rat and mud gate to tilt the silt and garbage inside.
[0013] The sewer assembly cover of the utility model is mosquito-proof, rat-proof, mud-proof and theft-proof, has controllable construction cost, is simple in structure, is easy to clean sludge and garbage, and reduces the later operation and maintenance cost of the urban sewer pipe network system.
