Description

Technical Field

[0001] The utility model relates to the technical field of municipal drainage, in particular to an end automatic control intercepting well applicable to a household outfall combined vertical pipe. Background Art

[0002] At present, the balcony drainage of many old communities is discharged into the rainwater pipeline through the external wall rainwater vertical pipe and finally transported to the river, polluting the river water quality. In order to prevent the pollution of the river water quality, sewage discharged is often collected by building a new sewage vertical pipe along the building external wall and finally discharged into the sewage pipe network. However, due to site conditions restrictions, such as podium buildings or other facilities have been built on the first floor of some communities, there is no effective pipe position for the newly built vertical pipe, and the coordination difficulty is great. Therefore, the problem cannot be solved by building a new vertical pipe, and only the existing rainwater vertical pipe can be used for transformation.

[0003] To address the problem of rain and sewage separation in the above rain and sewage combined pipeline, an intercepting well is often used for sewage interception and separation. The intercepting well is used in the rain and sewage combined system to separate rainwater and sewage. The sewage and rainwater flowing through the intercepting well usually mix with various solid impurities, which easily affect the drainage performance of the intercepting well. For this reason, a filter box for filtering solid impurities is generally provided at the inlet pipeline of the intercepting well. To ensure the sewage passing rate of the filter box, it is necessary for workers to go down into the intercepting well to clean the filter box regularly. However, there is a problem in the current design of the intercepting well that the filter box cannot be easily removed or replaced, which makes workers need to work in the well for a longer time and are more easily affected by the polluted gas in the well. Summary of the Invention

[0004] The purpose of the utility model is to solve the problem in the prior art that the filter box cannot be easily removed or replaced, which makes workers need to work in the well for a longer time and are more easily affected by the polluted gas in the well, and to propose an end automatic control intercepting well applicable to a household outfall combined vertical pipe.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme:

[0006] An end automatic control intercepting well applicable to a household outfall combined vertical pipe, including a well body, a combined vertical pipe is installed on the right side of the well body, a sewage intercepting pipe is installed on the left side of the well body, and a rainwater pipe is installed at the front end of the well body; a filter screen plate is arranged on the side of the combined vertical pipe close to the well body, and the filter screen plate is connected to the combined vertical pipe through an installation mechanism.

[0007] In some embodiments, the combined vertical pipe, the sewage intercepting pipe and the rainwater pipe are respectively communicated with the inner cavity of the well body.

[0008] In some embodiments, the upper part of the sewage intercepting pipe orifice partially overlaps with the lower part of the rainwater pipe orifice in height.

[0009] In some embodiments, the installation mechanism includes two fixing plates that are spaced parallel to each other on one side of the filter screen plate. A set of guide rods are respectively inserted through the fixing plates. A slider is provided at one end of the guide rod, and a groove matching the slider is formed on the inner wall of the confluence riser.

[0010] In some embodiments, a baffle is provided at the other end of the guide rod, and a spring is connected between the two baffles.

[0011] In some embodiments, a chute is further formed on the inner wall of the confluence riser. The chute is communicated with the groove. The depth of the chute is less than that of the groove, and the width of the chute gradually increases along the direction away from the groove.

[0012] In some embodiments, the confluence riser includes a vertical section and a horizontal section, and the filter screen plate is installed in the horizontal section of the confluence riser.

[0013] In some embodiments, a float valve is provided at the pipe orifice of the sewage interception pipe.

[0014] In some embodiments, it further includes a well cover. The well body has an opening at the top, and the well cover is movably installed at the opening at the top of the well body.

[0015] Compared with the prior art, the present utility model provides an automatic control intercepting well at the end of a household outfall confluence riser, which has the following beneficial effects.

[0016] In the present utility model, the filter screen plate is connected to the confluence riser through the installation mechanism. When the solid impurities intercepted and accumulated by the filter screen plate are too much, maintenance personnel can open the well cover on a sunny day, enter the well through the ladder, pull the two baffles closer to each other, compress the spring, so that the slider disengages from the groove, then take out the old filter screen plate, and then put in a new filter screen plate. The slider enters the groove along the chute. Under the extrusion of the spring, the filter screen plate is fixed to the inner wall of the confluence riser. The operation is simple and convenient, reducing the working hours in the well and helping to improve the use safety of the intercepting well.

[0017] Parts not involved in this device are the same as or can be implemented by the prior art. The present utility model makes the control method of the intercepting well simpler and more effective, and the operation of replacing the filter screen plate is simple and convenient, reducing the working hours in the well.

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0026] Refer to Figures 1-4 , an end automatic control intercepting well applicable to the household outfall confluence riser, including a well body 1, a confluence riser 2 is installed on the right side of the well body 1, a sewage intercepting pipe 3 is installed on the left side of the well body 1, and a rainwater pipe 4 is installed at the front end of the well body 1; a filter screen plate 5 is arranged on one side of the confluence riser 2 close to the well body 1, and the filter screen plate 5 is connected to the confluence riser 2 through an installation mechanism.

[0027] Specifically, the confluence riser 2, the sewage intercepting pipe 3 and the rainwater pipe 4 are respectively communicated with the inner cavity of the well body 1. Further, the upper part of the pipe orifice of the sewage intercepting pipe 3 and the lower part of the pipe orifice of the rainwater pipe 4 partially overlap in height, so as to ensure that when the water level of the rain and sewage is above the upper part of the pipe orifice of the sewage intercepting pipe 3, both the sewage intercepting pipe 3 and the rainwater pipe 4 can drain water to share the inlet load of the sewage treatment plant.

[0028] Please refer to Figure 2 again, the installation mechanism includes two fixed plates 6 distributed in parallel at intervals on one side of the filter screen plate 5, a group of guide rods 7 are respectively penetrated through the fixed plates 6, a slide block 8 is arranged at one end of the guide rod 7, and a groove 9 matching the slide block 8 is opened on the inner wall of the confluence riser 2.

[0029] Specifically, a baffle 10 is provided at the other end of the guide rod 7, and a spring 11 is connected between the two baffles 10. By pulling the two baffles 10 closer to each other, the spring 11 is compressed, causing the slider 8 to disengage from the groove 9.

[0030] In this embodiment, a chute 12 is also formed on the inner wall of the confluence riser 2. The chute 12 communicates with the groove 9. The depth of the chute 12 is less than that of the groove 9, and the width of the chute 12 gradually increases in the direction away from the groove 9. The chute 12 guides the slider 8, facilitating the placement of the filter screen plate 5 into the confluence riser 2.

[0031] Specifically, the confluence riser 2 includes a vertical section and a horizontal section, and the filter screen plate 5 is installed in the horizontal section of the confluence riser 2. The vertical section of the confluence riser 2 is responsible for connecting the water discharge branch pipes of each floor of the building.

[0032] In this embodiment, a float valve 13 is provided at the orifice of the sewage interception pipe 3. The working principle of the float valve 13 is that the float in the float chamber controls the opening or closing of a valve depending on the rise and fall of the liquid level in the well body 1.

[0033] In addition, it further includes a manhole cover 14. The well body 1 has an opening at the top, and the manhole cover 14 is movably installed at the opening at the top of the well body 1.

[0034] The working principle of the present utility model is as follows:

[0035] During implementation, the vertical section of the confluence riser 2 is connected to the water discharge branch pipes of each floor of the building. Sewage enters the well body 1 through the horizontal section of the confluence riser 2, and the sewage interception pipe 3 is connected to the sewage treatment plant. Under sunny conditions, the combined sewage is discharged into the well body 1 through the confluence riser 2. The float valve 13 is in the open state, and the combined sewage enters the municipal sewage system through the sewage interception pipe 3 and finally enters the sewage treatment plant. Under the initial rain condition, the initial rainwater enters the well body 1 through the confluence riser 2, and the water level in the intercepting well starts to rise. When the water level does not reach the preset elevation, the float valve 13 is still in the open state, and the initial rainwater enters the municipal sewage system through the sewage interception pipe 3 and finally enters the sewage treatment plant. Under rainy conditions, the rainwater enters the well body 1 through the confluence riser 2, and the water level in the well body 1 starts to rise rapidly. When the water level exceeds the preset elevation, the float valve 13 closes, and the rainwater is discharged into the municipal rainwater system through the rainwater pipe 4, thereby effectively separating the sewage and rainwater discharged from the building.

[0036] In summary, the present utility model automatically controls the opening and closing of the float valve 13 by the level of the liquid in the well body 1, thereby achieving reasonable separation of rainwater and sewage, making the control method of the intercepting well simpler and more effective, facilitating on-site construction and subsequent maintenance.

[0037] When the solid impurities intercepted and accumulated by the filter screen plate 5 are excessive, maintenance personnel can open the manhole cover 14 on a sunny day, enter the well through the ladder, pull the two baffles 10 closer to each other, squeeze the spring 11, so that the slider 8 disengages from the groove 9, then take out the old filter screen plate 5, and then put in a new filter screen plate 5. The slider 8 enters the groove 9 along the chute 12. Under the extrusion of the spring 11, the filter screen plate 5 is fixed to the inner wall of the confluence vertical pipe 2. The operation is simple and convenient, reducing the working hours in the well.
