Description

Technical Field

[0001] The present application relates to the technical field of municipal interception engineering, and in particular to a solar-powered flexible interception well. Background Art

[0002] Interception wells are underground wells that separate urban sewage and rainwater for the purpose of rainwater drainage. Initial rainwater is intercepted and sent to a sewage treatment plant for treatment. When the rainwater quality reaches a certain level, the interception gate is closed and the interception canal is abandoned.

[0003] In the related art, the intercepting well is usually equipped with an electric intercepting valve, which adopts a valve plate structure. When the valve plate is rotated to maintain a certain inclination angle with the axis of the valve body, sewage can flow through the gap between the valve plate and the valve body.

[0004] Since the angle between the valve plate and the valve body axis remains stable, the diameter of the sewage flow between the valve plate and the valve body also remains unchanged. Therefore, when the sewage inflow changes, it is difficult for the shut-off valve to adaptively adjust the drainage rate in time, so there is an obvious deficiency. Utility Model Content

[0005] In order to improve the sewage discharge effect, the present application provides a solar-powered flexible interception well.

[0006] The solar-powered flexible interception well provided in this application adopts the following technical solution:

[0007] A solar flexible intercepting well comprises a well body, wherein a sewage inlet pipe, a rainwater valve and a sewage intercepting valve are arranged on the side wall of the well body, the rainwater valve is connected to a rainwater pipe for discharging rainwater into a river, the sewage intercepting valve is connected to a sewage pipe for discharging sewage into a sewage treatment plant, the sewage intercepting valve comprises a valve body and a flexible airbag located in the valve body, the valve body and the flexible airbag are both hollow inside and open at both ends, the valve body and the ends of the flexible airbag correspond to each other one by one and are closed, the valve body and the flexible airbag are bonded at circumferential intervals, an air station for inflating the flexible airbag and the valve body is arranged on the ground, an air inlet and an air outlet are arranged on the outer side wall of the valve body, an air pipe is connected between the air inlets of the air station, and an exhaust valve is arranged at the air outlet.

[0008] By adopting the above technical solution, the air station fills air between the flexible airbag and the valve body through the air pipe, and the part of the flexible airbag that is not bonded to the valve body bulges toward the center line of the valve body, thereby achieving the effect of intercepting and controlling the drainage rate. When the amount of sewage increases and is not interfered with, the air between the flexible airbag and the valve body is further squeezed by the sewage, so that the drainage rate of the valve body can be adaptively increased to a certain extent, thereby improving the drainage effect.

[0009] Optionally, both ends of the valve body are bolted with flange rings, and the end of the flexible airbag is clamped between the flange ring and the end of the valve body.

[0010] By adopting the above technical solution, the end of the flexible airbag is clamped between the end of the valve body and the flange ring, so that when the flexible airbag is aged, workers can replace the flexible airbag more conveniently.

[0011] Optionally, a mounting support is arranged outside the rainwater valve for pressing its end against the side wall of the well body, and a sealing ring gasket is arranged between the end of the rainwater valve and the side wall of the well body.

[0012] By adopting the above technical solution, the sealing ring gasket improves the sealing effect between the rainwater valve and the side wall of the well body, and reduces the possibility of sewage leaking out from between the rainwater valve and the side wall of the well body when the flexible air bag completely cuts off the channel inside the rainwater valve.

[0013] Optionally, a solar power generation group is arranged on the ground, and the gas station is electrically connected to the solar power generation group through a control system.

[0014] By adopting the above technical solution, on sunny days, the solar power generation group can supply electricity to the gas station, achieving self-sufficiency in the operation of the electrical components of the interception well. At the same time, the excess electricity can also be supplied to the city electricity, thereby complementing the city electricity.

[0015] Optionally, the rainwater valve is higher than the sewage interception valve, and a liquid level meter electrically connected to a control system is provided on the side wall of the well body.

[0016] By adopting the above technical solution, on sunny days and at the beginning of rainfall, the rainwater valve is closed, the sewage interception valve is opened, and the sewage and initial rainwater are sent to the sewage treatment plant through the sewage pipe for treatment. As the rainfall increases, the rainwater level in the well gradually rises. When it reaches the preset water level, the rainwater valve opens, the sewage interception valve closes, and the rainwater is directly discharged into the river through the rainwater pipe. When the rainfall decreases or the rain stops, the water level in the well drops, and the liquid level meter detects the water level in real time. When the water level is lower than the preset water level, the rainwater valve and the sewage interception valve automatically return to their initial state.

[0017] Optionally, a camera electrically connected to a control system is arranged on the side wall of the well body.

[0018] By adopting the above technical solution, the camera can capture the sewage situation in the well in real time and feed it back to the control system. When blockage or other emergencies occur, the control system can warn the monitoring personnel in the first time.

[0019] Optionally, a COD detector electrically connected to the control system and used to detect the water quality in the well body is placed on the ground.

[0020] By adopting the above technical solution, the COD detector can detect the water quality of sewage in the well body. When the sewage reaches the discharge standard, the rainwater valve will open to allow rainwater to be discharged directly into the river.

[0021] Optionally, a beam is arranged on the side wall of the well body, and the rainwater valve is mounted on the beam.

[0022] By adopting the above technical solution, since the rainwater valve is heavy, the frame beam can play a strong supporting role for the rainwater valve, thereby ensuring the stability of the connection between the rainwater valve and the side wall of the well body.

[0023] Optionally, the frame beam includes two arc-shaped rotating frame arms, the ends of the rotating frame arms are hinged on the side walls of the well body, the other two ends of the two rotating frame arms are pressed against each other at the hinged ends of the well body, and the inner arc surfaces of the rotating frame arms face downward.

[0024] By adopting the above technical solution, when the rainwater valve is damaged and needs to be hoisted out for repair or replacement, the worker disconnects the connection between the rainwater valve and the rotating frame arm, and then manually rotates the rotating frame arm to make way for the lifting of the rainwater valve. The rotating frame arm does not need to be removed from the side wall of the well body, thereby simplifying the repair or replacement of the rainwater valve.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. The air station fills air between the flexible airbag and the valve body through the air pipe, and the part of the flexible airbag that is not bonded to the valve body bulges toward the center line of the valve body, which can intercept and control the drainage rate. When the amount of sewage increases and is not interfered with, the air between the flexible airbag and the valve body is further squeezed by the sewage, so that the drainage rate of the valve body can be adaptively increased to a certain extent, thereby improving the drainage effect;

[0027] 2. On sunny days, the solar power generation group generates electricity to supply the gas station, achieving self-sufficiency in the operation of the electrical components supporting the interception well. At the same time, the excess electricity can also be supplied to the city electricity, thereby complementing the city electricity;

[0028] 3. On sunny days and at the beginning of rainfall, the rainwater valve is closed and the sewage interception valve is opened. Sewage and initial rainwater are sent to the sewage treatment plant through the sewage pipe for treatment. As the rainfall increases, the rainwater level in the well gradually rises. When it reaches the preset water level, the rainwater valve is opened and the sewage interception valve is closed. The rainwater is directly discharged into the river through the rainwater pipe. When the rainfall decreases or stops, the water level in the well drops, and the liquid level meter detects the water level in real time. When the water level is lower than the preset water level, the rainwater valve and the sewage interception valve automatically return to their initial state. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The following is combined with Figure 1-3 This application is described in further detail.

[0034] The embodiment of the present application discloses a solar-powered flexible interception well.

[0035] Reference Figure 1 The solar flexible intercepting well includes a well body 1, and a sewage inlet pipe 2, a rainwater valve 3 and a sewage intercepting valve 4 are arranged on the side wall of the well body 1. The rainwater valve 3 is higher than the sewage intercepting valve 4. The rainwater valve 3 is connected to a rainwater pipe 5 for discharging rainwater into a river, and the sewage intercepting valve 4 is connected to a sewage pipe (not shown in the figure) for discharging sewage into a sewage treatment plant.

[0036] Reference Figure 1 and Figure 2 The sewage interception valve 4 includes a valve body 7 bolted to the side wall of the well body 1 and a flexible air bag 6 located in the valve body 7. The valve body 7 and the flexible air bag 6 are both straight tube-shaped, hollow inside and open at both ends, and the ends of the valve body 7 and the flexible air bag 6 correspond one to one.

[0037] Reference Figure 1 and Figure 2 Both ends of the valve body 7 are bolted with flange rings 12, and the end of the flexible airbag 6 is sandwiched between the flange ring 12 and the end of the valve body 7. When the flexible airbag 6 is aged and needs to be replaced, workers can disassemble and assemble the flexible airbag 6 more conveniently.

[0038] Reference Figure 1 and Figure 2 The valve body 7 and the flexible airbag 6 are bonded at intervals at multiple locations along the circumference, and cavities are formed at the unbonded positions. An air station (not shown in the figure) for inflating the cavity is arranged on the ground, and the air station is electrically connected to the control system.

[0039] An air inlet 8 and an air outlet 9 are arranged between the inner and outer side walls of the valve body 7. An air pipe 10 is connected between the air inlet 8 and the gas station. The air pipe 10 adopts a hose in the prior art. An exhaust valve 11 is threadedly connected at the air outlet 9, and the exhaust valve 11 is electrically connected to the control system.

[0040] Reference Figure 1 and Figure 2 The control system starts the air station, and the air station inflates the cavity through the air pipe 10. The position of the flexible airbag 6 relative to the cavity bulges toward the direction close to the axis of the valve body 7, so that the diameter of the valve body 7 for sewage to flow gradually becomes smaller, thereby controlling the drainage rate and interception of sewage.

[0041] Reference Figure 1 and Figure 2 The rainwater valve 3 adopts the same structure as the sewage interception valve 4, and both are supplied with gas by the gas station, and have the functions of adjusting the rainwater drainage rate and interception. When the drainage rate needs to be increased, the control system opens the exhaust valve 11.

[0042] The rainwater valve 3 and the sewage intercepting valve 4 are both threadedly connected with a pressure sensor (not shown in the figure) which is in communication with the cavity. The pressure sensor is electrically connected to the control system and is used to detect the air pressure in the cavity to avoid over-inflation and the possibility of the flexible airbag 6 exploding due to excessive cavity pressure.

[0043] Reference Figure 1 and Figure 2 A solar power generation group 15 is arranged on the ground, the gas station is electrically connected to the solar power generation group 15 through a control system, and the solar power generation group 15 is connected to the city power.

[0044] On sunny days, the solar power generation group 15 supplies power to the electrical devices equipped in the interception well, and the excess power can be supplied to the city power. When the solar power generation group 15 is insufficient, the interception well is supplied with power by the city power, thereby realizing the complementarity of the solar power generation group 15 and the city power.

[0045] Reference Figure 1 and Figure 2 On sunny days and in the early stages of rainfall, the rainwater valve 3 is closed, the sewage interception valve 4 is opened, and the sewage and initial rainwater are sent to the sewage treatment plant through the sewage pipe for treatment. As the rainfall increases, the rainwater level in the well body 1 gradually rises. When it reaches the preset water level, the rainwater valve 3 is opened, the sewage interception valve 4 is closed, and the rainwater is directly discharged to the river through the rainwater pipe 5.

[0046] Reference Figure 1 and Figure 2 A liquid level meter 16 electrically connected to the control system is bolted at a higher position on the side wall of the well body 1. When the rainfall decreases or the rain stops, the water level in the well body 1 drops, and the liquid level meter 16 detects the water level in real time. When the water level is lower than the preset water level, the rainwater valve 3 and the sewage interception valve 4 automatically return to their initial states.

[0047] Reference Figure 1 and Figure 2 A COD detector (not shown in the figure) electrically connected to the control system is placed on the ground. The COD detector can detect the water quality of the sewage in the well body 1. Only when the sewage reaches the discharge standard and the rainwater level exceeds the preset water level, the rainwater valve 3 will open to allow rainwater to be discharged directly into the river.

[0048] Reference Figure 1 and Figure 2 The rainwater valve 3 is externally bolted with a flange ring 12 at its end to press against a mounting support 13 on the side wall of the well body 1 , and a sealing ring gasket 14 is placed between the flange ring 12 and the side wall of the well body 1 .

[0049] The sealing ring gasket 14 improves the sealing effect between the rainwater valve 3 and the side wall of the well body 1, and reduces the possibility of sewage leaking out from between the rainwater valve 3 and the side wall of the well body 1 when the flexible airbag 6 completely cuts off the channel in the rainwater valve 3.

[0050] Reference Figure 3 A frame beam is arranged in the well body 1, and the frame beam includes two arc-shaped rotating frame arms 18. One end of the rotating frame arm 18 is hinged on the side wall of the well body 1, and the other two ends of the two rotating frame arms 18 are pressed against the well body 1. The inner arc surface of the rotating frame arm 18 faces downward, and the outer wall of the rainwater valve 3 is mounted on the two rotating frame arms 18.

[0051] Reference Figure 3 When the rainwater valve 3 is damaged and needs to be hoisted out for repair or replacement, the worker disconnects the connection between the rainwater valve 3 and the rotating frame arm 18, and then manually rotates the rotating frame arm 18 to make way for the lifting of the rainwater valve 3. The rotating frame arm 18 does not need to be removed from the side wall of the well body 1, thereby simplifying the repair or replacement of the rainwater valve 3.

[0052] Reference Figure 3 A camera 17 electrically connected to the control system is mounted on the side wall of the well body 1. The camera 17 can take real-time photos of the sewage in the well body 1 and feed back the information to the control system. When a blockage or other emergency occurs, the control system can immediately warn the monitoring personnel.

[0053] The implementation principle of a solar flexible interception well in the embodiment of the present application is:

[0054] Sewage flows into the well body 1 through the rainwater pipe 5, and the COD detector detects the water quality of the sewage in the well body 1 in real time. On sunny days and at the beginning of rainfall, the rainwater valve 3 is closed, the sewage interception valve 4 is opened, and the sewage and initial rainwater are sent to the sewage treatment plant through the sewage pipe for treatment. As the rainfall increases, the rainwater level in the well body 1 gradually rises. When it reaches the preset water level and the COD detector detects that the water quality meets the standard, the rainwater valve 3 opens, the sewage interception valve 4 closes, and the rainwater is directly discharged into the river through the rainwater pipe 5. When the rainfall decreases or the rain stops, the water level in the well body 1 drops, and the liquid level meter 16 detects the water level in real time. When the water level is lower than the preset water level, the rainwater valve 3 and the sewage interception valve 4 automatically return to their initial state.

[0055] The air station fills air between the flexible airbag 6 and the valve body 7 through the air pipe 10, and the part of the flexible airbag 6 not bonded to the valve body 7 bulges toward the center line of the valve body 7, thereby achieving the effect of intercepting flow and controlling the drainage rate.

[0056] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
