Description

Technical Field

[0001] This utility model relates to the field of municipal drainage technology, and in particular to a suspended self-tilting diversion device for the renovation of combined sewer systems in communities along rivers. Background Technology

[0002] With the advancement of urban renewal and the renovation of pipe networks in old combined sewer systems along rivers, rainwater and sewage separation and overflow control have become crucial aspects of improving river water quality. However, existing combined sewer systems have the following technical deficiencies in practical applications, making them difficult to meet the renovation requirements: Poor spatial adaptability: Most diversion devices rely on fixed installation on the ground or underground, and cannot be directly fixed to the river retaining wall. However, the ground space in riverside communities is often narrow and the underground pipe network is complex, which makes the installation of the device difficult and occupies a lot of space. Insufficient water flow control and diversion accuracy: The lack of a dedicated interception box to constrain water flow results in turbulent flow of sewage and rainwater, making precise diversion difficult; moreover, the flap structure mostly relies on electric drive (such as liquid level sensor, rain sensor and electric valve), which is not only costly and complex to maintain, but also has the risk of failure in the event of power failure. Some flaps without drive lack reliable reset and limit structures, which are prone to loss of control of flap angle due to water flow impact, and cannot adapt to different flow conditions. The problem of sludge blockage is prominent: the sewage transported by the combined sewer contains a large amount of sludge. Most existing devices do not have a dedicated sludge discharge structure, and the sludge is easy to accumulate inside the device, resulting in pipe blockage, reduced diversion efficiency, frequent manual dredging, and high maintenance costs. Poor sewage transport connection: Some devices do not have a clear design for the connection between the drainage pipe and the existing inspection well in the community, which makes it difficult for the intercepted sewage to be smoothly connected to the sewage treatment system, and easily leads to sewage stagnation or leakage problems. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a suspended self-tilting diversion device for the renovation of combined sewer systems along rivers. It is particularly suitable for combined sewer systems along rivers with limited space, and can achieve efficient diversion of sewage and rainwater under sunny, light rain and heavy rain conditions, while solving the problem of sludge deposition and blockage.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A suspended self-tipping diversion device for the renovation of combined sewer systems along rivers includes: The intercepting box is fixed to the retaining wall of the river channel, with an opening at the top, and a sludge discharge pipe for discharging sludge is fixedly connected to the bottom of the intercepting box. The self-controlled flap is hinged to the intercepting box and covers the opening. A limit spring is fixedly connected to the bottom of the self-controlled flap, and the other end of the limit spring is fixedly connected to the inner wall of the side where the flap is installed in the intercepting box. A combined drain pipe is fixedly connected to one side wall opposite to the interceptor box and is used to receive sewage or combined water. A drain pipe is fixedly connected to the other side wall and is connected to a nearby inspection well.

[0005] Furthermore, it also includes a suspension bracket, which is fixed to the retaining wall by bolts, and the intercepting box is fixed to the suspension bracket by self-tapping screws.

[0006] Furthermore, a pad is provided between the intercepting box and the retaining wall, and the pad is fixed to the retaining wall by expansion bolts. The pad is located below the suspension bracket.

[0007] Furthermore, a limit rod is fixedly connected to the suspension bracket, and the limit rod is located above the self-controlled flap to limit the opening angle of the self-controlled flap.

[0008] Furthermore, the bottom of the intercepting box is designed in a cone shape.

[0009] Furthermore, the intercepting box has an overflow port on its side away from the retaining wall, and the overflow port is located below the top surface of the intercepting box.

[0010] Furthermore, the overflow port is fixedly connected to a guide plate, which protrudes from the side of the intercepting box.

[0011] Furthermore, a sludge discharge valve is installed on the sludge discharge pipe.

[0012] Furthermore, the self-controlled flap is connected to the interception box via a hinge.

[0013] Furthermore, the self-control flap is made of aluminum alloy plate, and the interception box is made of stainless steel.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. Strong spatial adaptability: Through the combination of interception box and suspension bracket, it can be directly fixed to the river retaining wall without occupying ground or underground space, perfectly adapting to the renovation scenario of combined sewer systems along the river where space is limited.

[0015] 2. Reliable and low-cost diversion: The self-controlled flap achieves pure mechanical automatic control through limit springs, eliminating the need for electric equipment and sensors. This not only reduces equipment costs and maintenance difficulty but also avoids the risk of failure during power outages. It can accurately adapt to the diversion needs of different working conditions, such as sunny days, light rain, and heavy rain.

[0016] 3. Solve the problem of sludge blockage: The conical bottom of the intercepting box, in conjunction with the sludge discharge pipe and sludge discharge valve, can regularly discharge sludge, greatly reducing sedimentation and blockage, reducing maintenance frequency by more than 60%, and lowering manual maintenance costs.

[0017] 4. Protecting river water quality: Under sunny and light rain conditions, sewage and initial rainwater can be 100% intercepted and diverted to the sewage treatment system. Under heavy rain conditions, only excess clean rainwater is discharged into the river, effectively reducing pollutants entering the river and improving the protection of river water quality.

[0018] 5. Easy installation and maintenance: The device adopts a modular design, and the suspension bracket is connected to the box with bolts, which is easy to disassemble; the drainage pipe is directly connected to the existing inspection well, without the need for large-scale modification of the pipe network, resulting in a short construction period and low cost.

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0022] like Figures 1-2 As shown, a suspended self-tilting diversion device for the renovation of combined sewer systems along a river includes a diversion box 1, a self-controlled flap 2, a limit spring 11, a merging pipe 3, a drainage pipe 4, a suspension bracket 5, a pad 6, a limit rod 7, a sludge discharge pipe 8, a sludge discharge valve 9, a hinge, and a guide plate 10.

[0023] The intercepting tank 1 is made of stainless steel, which has good corrosion resistance and can adapt to the humid environment of the river. The bottom of the intercepting tank 1 is designed in a cone shape, which facilitates the accumulation of sludge at the bottom under gravity, making it easier to discharge later. The top of the intercepting tank 1 is provided with an opening for discharging water flow exceeding the treatment capacity.

[0024] The self-regulating flap 2 is made of aluminum alloy plate, which is lightweight yet strong enough to meet usage requirements. The self-regulating flap 2 is hinged to the intercepting tank 1, covering the opening at the top of the intercepting tank 1. A limit spring 11 is fixedly connected to the bottom of the self-regulating flap 2, and the other end of the limit spring 11 is fixedly connected to the inner wall of the intercepting tank 1 on the side where the flap is installed. The elastic force of the limit spring 11 can be selected according to the actual drainage situation to realize the automatic opening and closing of the self-regulating flap 2 under different water volumes.

[0025] The combined sewer pipe 3 is fixedly connected to the opposite side wall of the interceptor box 1 to receive sewage or combined runoff from the combined sewer system. A drain pipe 4 is fixedly connected to the other side wall of the interceptor box 1. The drain pipe 4 is connected to a nearby inspection well to transport the sewage or initial rainwater that needs to be treated to the sewage treatment system.

[0026] The suspension bracket 5 is bolted to the retaining wall 12 of the river channel, and the intercepting box 1 is fixed to the suspension bracket 5 with self-tapping screws, realizing the suspended installation of the device and adapting to the installation environment along the river channel. A pad 6 is provided between the intercepting box 1 and the retaining wall 12. The pad 6 is fixed to the retaining wall 12 with expansion bolts, and the pad 6 is located below the suspension bracket 5. The pad 6 can increase the connection stability between the intercepting box 1 and the retaining wall 12 and reduce vibration during device operation.

[0027] A limit rod 7 is fixedly connected to the suspension bracket 5. The limit rod 7 is located above the self-controlled flap 2 and is used to limit the opening angle of the self-controlled flap 2 to avoid damage to the spring or affect the normal operation of the device due to excessive opening of the flap.

[0028] An overflow outlet is provided on the side of the intercepting tank 1 away from the retaining wall 12. The overflow outlet is lower than the top surface of the intercepting tank 1. When the water level in the intercepting tank 1 reaches the height of the overflow outlet, the excess water can be discharged through the overflow outlet. A guide plate 10 is fixedly connected to the overflow outlet. The guide plate 10 protrudes from the side of the intercepting tank 1 and guides the direction of water flow, so that the overflowing water can be smoothly discharged into the river channel.

[0029] A sludge discharge pipe 8 is fixedly connected to the bottom of the interception box 1, and a sludge discharge valve 9 is installed on the sludge discharge pipe 8. By periodically opening the sludge discharge valve 9, the sludge collected at the bottom of the interception box 1 can be discharged through the sludge discharge pipe 8, ensuring the normal operation of the device.

[0030] The working process of this device is as follows: On sunny days, only domestic sewage flows into the intercepting tank 1 through the combined sewer 3. The water volume is small, and the automatic control flap 2 remains closed under the action of the limit spring 11. The sewage flows into the inspection well through the drain pipe 4 and enters the sewage treatment system. In the early stages of rainy days, the combined water volume gradually increases, the water level in the intercepting tank 1 rises, and the pressure of the water on the automatic control flap 2 gradually increases. When the pressure is greater than the elastic force of the limit spring 11, the automatic control flap 2 opens, and the initial rainwater still enters the sewage treatment system through the drain pipe 4. As the rainfall increases, the combined water volume further increases, and the water level in the intercepting tank 1 rises rapidly to the overflow outlet. Later, the rainwater is discharged into the river through the overflow outlet and the guide plate 10, realizing the reasonable diversion of rainwater.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
