Description

Technical Field

[0001] The utility model relates to the technical field of municipal drainage, in particular to an intelligent flushing and storage well with integrated drainage pipelines. Background Art

[0002] The accumulation of sediment in pipes is a very common problem. The accumulated sediment in drainage pipes will reduce the flow cross-sectional area, leading to pipe blockage, which may lead to the risk of urban pipe overflow and urban waterlogging. Pollutants attached to the surface of sediments will have adverse effects on the discharged water and aquatic organisms.

[0003] In recent decades, people have proposed various technologies for removing sediments from pipelines and gradually applied them in engineering. These technologies are mainly divided into three categories: the first category: when manually cleaning large-diameter pipelines, it mainly depends on workers to go down the well to manually remove or use flushing machines to clean. This dredging task is arduous, the environment is harsh, and the work efficiency is low. Due to the possible presence of methane in the pipeline, underground workers often suffer from poisoning incidents, and their personal safety cannot be guaranteed; the second category: the technology of mechanical flushing of small-diameter pipelines includes: ① high-pressure water jet dredging method, ② winch dredging method, ③ hydraulic flushing dredging method, ④ trench cleaning machine dredging method, ⑤ dredging ball method, these This method has the following disadvantages: high cost, poor dredging effect, possible secondary pollution, large consumption of clean water, and difficulty in adapting to complex terrain. Although there are a small number of vehicle-mounted dredging machines that use high-pressure water jets to dredge pipes, the power is usually above 15KW, which consumes a lot of energy and wastes water resources. In addition, the operating costs of high-pressure pumps and nozzles are also very high. The third category: The automatic flushing gate device is controlled by water level. When the water level in the upstream water storage tank reaches the set value, the gate automatically opens, triggering a hydraulic flushing wave, which can effectively remove sediments in the pipe. During the flushing process, the unfixed sediment particles are transported to the bottom of the downstream sedimentation tank or the discharge port with the water flow.

[0004] In the current drainage pipe system, the common pipe flushing design adopts electric or hydraulic devices to control the opening and closing of the flushing gate. However, this gate can only partially intercept the upstream water level and cannot completely intercept the upstream water level, and does not solve the problem of downstream water backflow. In addition, the existing fixed gates or impoundments are often fixed in the pipe flushing well, which brings certain difficulties to the subsequent inspection and maintenance.

[0005] At present, there is a Chinese patent authorization announcement number CN109113169B that discloses an automatic flushing device for drainage pipes. This patent uses a locking mechanism to automatically control the opening and closing of the gate using the water level in the water storage tank, thereby realizing automatic flushing of the pipe using water from the drainage pipe. However, the disadvantage of this patent is that it is necessary to go down the well to inspect the gate, and it cannot prevent the problem of water backflow downstream.

[0006] In addition, a Chinese patent authorization announcement number CN103993652A discloses a non-powered interception and flushing door for self-flushing of drainage pipes. The non-powered interception and flushing door described in the patent includes an actuator, an interception door and a float water level control valve; the actuator is fixed to the top of the water inlet of the drainage pipe, and is equipped with a driving device. The interception door is connected to the actuator through a mechanical arm, and the float water level control valve is connected to the driving device inside the actuator through a connecting rod, which also has the problem of shortcomings.

[0007] Therefore, the applicant has found a solution to the above-mentioned problem through beneficial exploration and research, and the technical solution to be introduced below is produced in this context. Utility Model Content

[0008] The technical problem to be solved by the utility model is to provide a drainage pipeline integrated intelligent flushing and storage well to solve the above problems in view of the above shortcomings and defects of the prior art.

[0009] The technical problem to be solved by the present invention can be achieved by adopting the following technical solutions:

[0010] An integrated intelligent flushing and storage well for drainage pipes, characterized in that it comprises a detachable gate well and an upstream pipe arranged at one end of the gate well and connected to a pipe, and a downstream pipe arranged at the other end of the gate well and connected to another pipe, a liquid level sensor for monitoring the liquid level in the upstream pipe is arranged in the upstream pipe, a gate that can rise or fall and play an opening and closing role is arranged inside the gate well, and a driving device for controlling the opening or closing of the gate and connected to the liquid level sensor is also arranged inside the gate well;

[0011] When used in the initial rain storage pipeline, rainwater is collected into the rainwater pipeline through the road surface rainwater outlet and the rainwater connecting pipe, and the rainwater pipeline finally merges into the storage pipeline (upstream pipeline). When the liquid level in the storage pipeline (upstream pipeline) is in a gradually rising state, the liquid level sensor transmits a signal to the drive device, and the drive device starts working to control the gate to rise to a closed state. Subsequently, the gate completes the interception and storage action and begins to enter the next water storage state; Water storage: With the continuous inflow of water from the upstream pipeline, the downstream drainage pipeline does not discharge water due to the obstruction of the gate. At this time, the water level of the upstream pipeline of the gate gradually rises, thereby completing the water storage process and entering the next pipeline flushing; Pipeline flushing: With the liquid level of the upstream pipeline of the gate structure constantly rising to the designed maximum water level, the liquid level sensor transmits a signal to the drive device, and the drive control controls the gate to descend to an open state, releasing the water accumulated in the upstream pipeline of the gate, and using the power of water potential to flush the sediment or impurities in the pipeline, thereby completing the pipeline flushing process;

[0012] Similarly, when applied to rainwater pipes, the intensity of heavy rain gradually increases, the flow in the rainwater pipe increases sharply, the rainwater pipe is at full load, the water flow rate is very high, and the high-speed flowing rainwater carries the sediment in the pipe to the natural water body, or the intensity of heavy rain gradually decays, and the flow in the rainwater pipe gradually slows down, causing the water flow rate to slow down. The sediment carried into the pipe cannot be transported to the final outlet under the low-speed water flow. At this time, the liquid level sensor transmits a signal to the drive device, which starts the work to control the gate to rise to the closed state, and the subsequent operations are consistent with the above working principle.

[0013] In a preferred embodiment of the utility model, it also includes an electric hoist device which is arranged on the periphery of the gate shaft and is used to repair the gate.

[0014] In a preferred embodiment of the utility model, the interior of the gate shaft is respectively provided with a gate shaft, a control limiter operating table, an inspection rope, a guide rail, a gate shaft limiter, a gate traction rope, a gate closing body, a gate traction rope connecting port, a gate locking body, and an inspection rope chamber.

[0015] In a preferred embodiment of the present invention, the gate shaft is movably connected to the gate and embedded in the guide rail.

[0016] In a preferred embodiment of the present utility model, the gate traction rope connection port is arranged on the gate and connected to the gate traction rope, and the gate traction rope is connected to the driving device.

[0017] In a preferred embodiment of the utility model, the inspection rope is arranged in the inspection rope chamber, the lower end of the inspection rope is connected to the gate shaft limiter, and the upper end of the inspection rope is connected to the control limiter operating table.

[0018] In a preferred embodiment of the present invention, the gate closing body and the gate locking body are integrally formed.

[0019] In a preferred embodiment of the utility model, the driving device includes an electric motor arranged inside the gate shaft and a swivel bearing platform arranged on the gate shaft, one end of the swivel bearing platform is connected to the electric motor, and the other end thereof is connected to the gate traction rope.

[0020] In a preferred embodiment of the present invention, the gate well is made of corrosion-resistant material.

[0021] In a preferred embodiment of the present utility model, the gate is arranged in a special-shaped structure and is made of corrosion-resistant material.

[0022] Due to the adoption of the above technical scheme, the beneficial effects of the utility model are: firstly, the equipment structure of the utility model is simple and the installation is convenient, and it is easy to transform the existing pipeline; secondly, the gate has the function of completely intercepting the upstream water flow and flushing, and effectively preventing the silt deposition of pollutants in the pipeline; thirdly, the gate in the gate well is designed to be detachable, which is convenient for lifting, replacement and maintenance; fourthly, when the water level of the river channel is extremely high during the flood season, the gate in the gate well located at the end of the rainwater pipe near the river outlet can be completely closed, which has the function of preventing the backflow of river water.

The electric hoist device includes an electric hoist gantry 18, a cross bar 19 provided on the electric hoist gantry 18, and connecting rods 20 provided at both ends of the cross bar 19 and connected to the gate traction rope connection port 14.

[0047] When the utility model is used and arranged in the initial rain regulating and storing pipeline, its working principle is as follows:

[0048] (See especially Fig.15 ) Assume that the initial rainwater storage pipeline is a series of N pipe sections for water storage, the diameter of the rainwater storage pipeline is greater than 3.5m, the length of each pipe section is L (generally more than 300m), and a detachable gate well 3 is set at each pipe section connection node. In addition, considering that the starting pipeline is not equipped with a gate well, the terminal pipeline is discharged to the municipal sewage pipeline by a sewage pump, and the terminal pipeline is not equipped with a gate well 3, then N pipe sections are equipped with N-1 gate wells; when flushing the pipeline, the gate well N-1 is opened from the end of the Nth pipe section to flush in sequence, the pipe section N is flushed N times, the pipe section N-1 is flushed N-1 times, the pipe section i is flushed i times, and the pipe 1 is flushed 1 time;

[0049] The process is as follows: initial rainwater is collected into the rainwater pipe through the road surface rainwater outlet and the rainwater connecting pipe, and the rainwater pipe finally flows into the initial rainwater regulating and storing pipe (upstream pipe 2). When the liquid level in the regulating and storing pipe (upstream pipe 2) is in a gradually rising state, the liquid level sensor 17 transmits a signal to the PLC control cabinet in the motor 6, and the PLC control cabinet starts the driving end of the motor 6, and controls the gate 4 to rise to a closed state through the rotating bearing platform 7 and the gate traction rope 12. At this time, the gate 4 completes the interception and storage action and begins to enter the next water storage state; when storing water: with the continuous inflow of water from the upstream pipe 1, due to the obstruction of the gate 4, the downstream pipe 2 does not discharge water. At this time, the water level of the upstream pipe 1 of the gate 4 gradually rises, thereby completing the water storage process; when flushing the pipe: with the gate The liquid level in the upstream pipeline 1 of the gate 4 continues to rise to the set maximum water level. At this time, the liquid level sensor 17 transmits a signal to the PLC control cabinet in the motor 6. The PLC control cabinet starts the driving end of the motor 6, and controls the gate 4 to drop to an open state through the rotating bearing table 7 and the gate traction rope 12, releasing the water accumulated in the upstream pipeline 1 of the gate 4, and using the power of the water potential to flush the sediment or impurities in the pipeline, thereby completing the pipeline flushing process; when idle: the water collected in the initial rain regulation pipeline is released one by one to be flushed clean, and the gate 4 connected in series on the pipeline is in an open state from the end to the starting section. At this time, the initial rain regulation pipeline is in an idle state, and it is also the pre-stage of the next round of interception and storage; when maintenance: the gate 4 is detachable, (reference Fig. 9 ) It can be seen that the relative position relationship between the gate 4 and the guide rail 10, the gate 4 is hoisted out along the guide rail 10 by the electric hoist gantry 18;

[0050] (See especially Fig.16 ) Assume that the rainwater pipe is N pipe sections connected in series for drainage, the pipe diameter is less than 2m, and the length of each pipe section is L (according to the outdoor drainage specification GB50014-2021, Table 5.4.4, the maximum spacing of inspection wells in straight sections is 200m), and a detachable gate well is set at each pipe section connection node. In addition, considering that the starting pipe does not have a gate well and the end outlet directly discharges into the river, N pipe sections are set with N-1 gate wells; when flushing the pipe, the Nth pipe section at the end is flushed in sequence, pipe section N is flushed N times, pipe section N-1 is flushed N-1 times, pipe section i is flushed i times, pipe 1 is flushed 1 time, and so on;

[0051] The process is as follows: In the first stage, the intensity of the rainstorm gradually increases, the flow in the rainwater pipe increases sharply, the rainwater pipe is at full load, the water flow rate is very high, and the high-speed flowing rainwater carries the sediment in the pipe to the natural water body; In the second stage, the intensity of the rainstorm gradually decays, and the flow in the rainwater pipe gradually slows down, causing the water flow rate to slow down. The sediment carried into the pipe cannot be transported to the final outlet under the low-speed water flow. At this time, the liquid level sensor 17 transmits a signal to the PLC control cabinet inside the motor 6. The PLC control cabinet starts the drive end of the motor 6 and controls the gate 4 to rise to the closed state through the rotating bearing table 7 and the gate traction rope 12. At this time, the gate 4 completes the interception and storage action and begins to enter the next water storage state; when storing water: as the upstream pipe 1 continues to inflow water, the downstream pipe 2 does not discharge water due to the obstruction of the gate 4. , the water level of the upstream pipeline 1 of the gate 4 gradually rises, thereby completing the water storage process; when the pipeline is flushed: as the liquid level of the upstream pipeline 1 of the gate 4 continues to rise to the set highest level, at this time, the liquid level sensor 17 transmits a signal to the PLC control cabinet inside the motor 6, and the PLC control cabinet starts the driving end of the motor 6, and controls the gate 4 to descend to the open state through the rotating bearing table 7 and the gate traction rope 12, releases the water accumulated in the upstream pipeline 1 of the gate 4, and uses the power of the water potential to flush the sediment or impurities in the pipeline, thereby completing the pipeline flushing process; when idle: the rainwater collected in the pipeline is released and flushed one by one, and all gates 4 are in a descending state from the end to the starting section in turn, starting the next round of interception and storage process, and before that, the gate 4 has been open and is in an idle state; when maintenance: the gate 4 is detachable, (reference Fig. 9 ) It can be seen from the relative position relationship between the gate 4 and the guide rail 10 that the gate 4 is hoisted out along the guide rail 10 by the electric hoist gantry 18.
