Description

Technical Field

[0001] The utility model relates to the field of inspection wells, in particular to an inspection well based on a municipal sewage pipe network. Background Art

[0002] The municipal sewage network refers to the collection, treatment and discharge system of urban sewage. It is an important part of the urban infrastructure network. Its main functions include collecting, transporting and treating wastewater discharged by urban residents and enterprises, avoiding pollution and harm to the environment caused by sewage discharge, protecting public health, promoting urban sanitation and construction, improving the city's appearance and filling the gaps in urban construction. The inspection well based on the municipal sewage network is an important part of the sewage network system. The inspection well based on the municipal sewage network is mainly used for inspection and maintenance, intersection, turning and change processing, observation and monitoring, safety assurance and environmental protection. The existing inspection wells based on the municipal sewage network usually have a close distance between the inlet and outlet pipes and the bottom of the well. The accumulation of impurities at the bottom can easily cause pipe blockage, and it is usually necessary to open the well cover for inspection to know the internal water flow conditions. When blocked, it is not convenient to clean due to the deep bottom of the well. Utility Model Content

[0003] In order to overcome the existing inspection wells based on municipal sewage pipe networks, the inlet and outlet pipes are usually close to the bottom of the well, and the accumulation of impurities at the bottom can easily cause pipe blockage. It is usually necessary to open the well cover to check the internal water flow conditions. When blocked, it is not convenient to clean due to the deep bottom of the well.

[0004] The technical solution of the utility model is: an inspection well based on a municipal sewage pipe network, including an inspection well body component, a well cover component and a pollution cleaning component. The upper end of the inspection well body component is provided with a well cover component for opening and detecting water flow velocity, and the lower end of the inspection well body component is fixedly installed with a pollution cleaning component for cleaning precipitated impurities.

[0005] Preferably, by configuring the well body into a bottom-falling structure in which the water inlet and outlet pipes are far away from the bottom of the well, even if impurities are precipitated and accumulated at the bottom of the well, it is not easy to cause water blockage. By providing a flow rate detection module on the well cover, the water flow conditions inside the well body can be detected in real time without the need to frequently open the well cover assembly for inspection. By providing a cleaning assembly, the impurity particles deposited at the bottom of the well can be automatically pushed upwards, making cleaning faster and more efficient, and avoiding time-consuming and labor-intensive manual operations.

[0006] Preferably, the inspection well body assembly includes a well body, a water inlet pipe, a drain pipe, a filter, a sewage pipe, a control valve, a waterproof box and an installation hole. A water inlet pipe for introducing water is fixedly installed in the middle of the left end of the well body, a drain pipe for discharging water is fixedly installed in the middle of the right end of the well body, a filter for filtering impurities in the water is fixedly installed at one end of the drain pipe close to the well body, and an installation hole for installing a sewage cleaning component is opened in the middle of the lower end of the well body. By setting a filter at the outlet pipe, impurities can be filtered and blocked to prevent larger particles of impurities from entering the outlet pipe and causing blockage.

[0007] Preferably, a sewage pipe for discharging settled sludge is fixedly installed at the bottom of the front end of the well body, a control valve for controlling the inlet and outlet is provided on the outside of the sewage pipe, a pressure controller for controlling the pressure is provided on the outside of the control valve, a waterproof box for waterproofing is provided on the outside of the pressure controller, and a sealing door for opening and closing is provided at the front end of the waterproof box. By arranging a pressure controller on the control valve on the outside of the sewage pipe, all the sludge can be discharged from the sewage pipe by changing the pressure, so that the cleaning is more thorough.

[0008] Preferably, the manhole cover assembly includes a cover body, a block, a sealing ring, a limit column, a handle, and a flow rate detection module. The lower end of the cover body is fixedly connected with a block for engaging with the well body. The lower end side of the cover body is fitted with a sealing ring for preventing water leakage. The lower end side of the cover body is surrounded by a plurality of groups of limit columns for limiting the cover body. By setting the block to engage with the inside of the well body and by setting the limit column to engage with the outside of the well body, a double limiting effect can be achieved, making it difficult for the cover body to slide or deflect.

[0009] Preferably, two sets of handles are fixedly installed on the outer sides of the cover body opposite to each other on the left and right sides for easy opening and closing of the cover body, and a flow velocity detection module for detecting the flow velocity is embedded in the middle of the cover body. By setting the flow velocity detection module, the water flow conditions inside the well body can be grasped in real time.

[0010] Preferably, the flow velocity detection module includes a flow velocity detector, a waterproof connecting line and a flow velocity detection head. The flow velocity detector is embedded in the middle of the upper end of the cover body. The lower end of the flow velocity detector is electrically connected to the waterproof connecting line for transmitting flow velocity information. The lower end of the waterproof connecting line passes through the cover body and extends to the well body to be fixedly connected with a flow velocity detection head for sensing water flow velocity. The flow velocity detector is provided with a wireless connection module for connecting to an external device. By wirelessly connecting the flow velocity detection module to the external device, the water flow velocity inside the well body can be grasped in real time from the external related equipment, so that when the flow velocity abnormality is detected, the external device can issue an alarm, so that the staff can clear the blockage in the well body in time.

[0011] Preferably, the cleaning component includes a filter plate, an electric push rod, a telescopic cylinder and a waterproof cover. The filter plate is arranged at the bottom of the well body. The upper end of the electric push rod passes through the lower end of the well body and extends to the inside to control the up and down movement of the filter plate. The telescopic cylinder drives the filter plate to rise and fall synchronously by controlling the up and down movement of the electric push rod. The outer sleeves of the electric push rod and the telescopic cylinder are provided with a waterproof cover for protecting the electric push rod and the telescopic cylinder. By setting the telescopic cylinder to control the filter plate to automatically push out the impurities deposited at the bottom of the well, it is more convenient and quick, and can greatly improve the cleaning speed.

[0012] Beneficial effects of the utility model:

[0013] 1. Compared with the traditional inspection wells based on municipal sewage pipe networks, the distance between the inlet and outlet pipes is usually close to the bottom of the well, and the accumulation of impurities at the bottom can easily cause pipe blockage. It is usually necessary to open the well cover for inspection to know the internal water flow. When blocked, it is not convenient to clean due to the deep bottom of the well. By setting the well body into a bottom-drop structure with its inlet and outlet pipes far away from the bottom of the well, even if impurities at the bottom of the well are precipitated and accumulated, it is not easy to cause water blockage. By setting a filter at the outlet pipe, impurities can be filtered and blocked to prevent larger particles of impurities from entering the outlet pipe and causing blockage. By setting a flow rate detection module on the well cover, the water flow inside the well body can be detected in real time. The flow velocity detection head can be used to sense the water flow velocity. The waterproof connection line electrically connected to the flow velocity detection head and the flow velocity detection module can be used to transmit the detected water flow condition to the flow velocity detection module in the form of an electrical signal. Since the flow velocity detection module is internally provided with a wireless connection module for wireless connection with external devices, the water flow information can be transmitted to the external device in real time. When an abnormal flow velocity is detected, the external device can easily issue an alarm to remind the staff, so that the staff can clean up the blockage in the well body in time. Real-time detection through the flow velocity detection module is more convenient and quick, and avoids the time-consuming and laborious process of frequently opening the manhole cover assembly for inspection.

[0014] 2. By setting up a cleaning component, the impurity particles deposited at the bottom of the well can be automatically pushed upward, thereby facilitating cleaning. By setting up a telescopic cylinder, the electric push rod can be controlled to move up and down, so that the electric push rod can drive the filter plate to move upward to push the impurity particles to the wellhead for cleaning. The telescopic cylinder control can directly push out the impurities deposited in the well body for cleaning, which is more time-saving and labor-saving, and can greatly improve the cleaning efficiency. In addition, by setting up a sewage pipe, the residual sludge can be discharged from the sewage pipe. By setting a pressure controller on the control valve on the outside of the sewage pipe, all the sludge can be discharged from the sewage pipe by changing the pressure, making the cleaning more thorough. By setting a sealing ring at the lower end of the cover body, it can play a leak-proof role to prevent external impurities from entering and affecting the water flow rate and causing blockage. By setting a card block to be engaged with the inside of the well body, and by setting a limit column to be engaged with the outside of the well body, a double limit role can be played, so that the cover body is not easy to slide or deviate.

By setting the block 202 and the well body 1 01 is internally snap-fitted and connected with the outer side of the well body 101 by setting a limit column 204, which can play a double limiting role, making it difficult for the cover body 201 to slide or deflect. The outer sides of the cover body 201 are relatively arranged on the left and right sides and fixed with two groups of handles 205 for opening and closing the cover body 201. A flow rate detection module 206 for detecting the flow rate is embedded in the middle of the cover body 201. By setting the flow rate detection module 206, the water flow conditions inside the well body 101 can be grasped in real time.

[0027] See also Figure 6 In this embodiment, the flow rate detection module 206 includes a flow rate detector 207, a waterproof connection line 208 and a flow rate detection head 209. The flow rate detector 207 is embedded and installed in the middle of the upper end of the cover body 201.

[0028] See also Figure 7 In this embodiment, the cleaning component 3 includes a filter plate 301, an electric push rod 302, a telescopic cylinder 303 and a waterproof cover 304. The filter plate 301 is arranged at the bottom of the well body 101. The upper end of the electric push rod 302 passes through the lower end of the well body 101 and extends to the inside to control the filter plate 301 to move up and down. The telescopic cylinder 303 drives the filter plate 301 to move up and down synchronously by controlling the electric push rod 302 to move up and down. The outer side of the electric push rod 302 and the telescopic cylinder 303 is provided with a waterproof cover 304 for protecting the electric push rod 302 and the telescopic cylinder 303. By setting the telescopic cylinder 303 to control the filter plate 301 to automatically push out the impurities deposited at the bottom of the well, it is more convenient and quick, and can greatly improve the cleaning speed.

[0029] When working, first check the manhole body assembly 1 and the corresponding positions of the related embedding to ensure that the water inlet pipe 102 and the drain pipe 103 are unobstructed, and check whether the manhole cover assembly 2 is tightly covered, and whether the flow rate detection module 206 is connected to the external equipment;

[0030] Then, water is introduced into the well body 101 through the water inlet pipe 102, and the water flow is filtered through the filter screen 104, so that the filtered water is discharged from the drain pipe 103;

[0031] During the drainage process, the water flow velocity in the well body 101 is detected by the flow velocity detection module 206, the water flow velocity is sensed by the flow velocity detection head 209, and the detected water flow information is transmitted to the flow velocity detection module 206 through the waterproof connection line 208. The flow velocity detection module 206 transmits the water flow velocity information to external related equipment in real time through the wireless connection module;

[0032] When the water flow rate is detected to be too slow, the external connected device will sound an alarm to remind you of the abnormal water flow;

[0033] After receiving the abnormal water flow rate, the staff excavates, opens the manhole cover assembly 2, and cleans the impurity particles deposited in the well body 101 through the cleaning assembly 3;

[0034] The electric push rod 302 is controlled to move up and down by the telescopic cylinder 303, so that the electric push rod 302 drives the filter plate 301 to move upward to push the impurity particles to the wellhead for cleaning; the sludge will pass through the filter plate 301 and remain at the bottom of the well body 101;

[0035] Afterwards, the sludge is discharged through the sewage pipe 105, and the pressure is adjusted to a suitable value through the pressure controller on the control valve 106 outside the sewage pipe 105, and the control valve 106 is closed after all the sludge is discharged by using the pressure difference between the inside and outside;

[0036] After the final dredging is completed, the manhole cover assembly 2 is closed so that the sealing ring 203 at the lower end of the cover body 201 fits tightly with the upper end of the well body 101, and the blocking block 202 and the limiting column 204 limit the cover body 201 from the inside and outside respectively, and then the inspection well body and related structures are buried with soil to restore them to their original state.

[0037] Through the above steps, the staff will first check the inspection well body assembly 1 and the corresponding positions of the relevant embedding to ensure that the water inlet pipe 102 and the drainage pipe 103 are unobstructed, and check whether the well cover assembly 2 is tightly covered, and whether the flow rate detection module 206 is connected to the external equipment. Then, water is introduced into the well body 101 through the water inlet pipe 102, and the water flow is filtered through the filter 104 so that the filtered water is discharged from the drainage pipe 103. During the drainage process, foreign particles continue to settle to the bottom of the well. By setting the well body 101 as a bottom-falling structure in which the water inlet pipe 102 and the water outlet pipe are far away from the bottom of the well, even if the impurities at the bottom of the well are precipitated and accumulated, it is not easy to cause water blockage, and the water flow rate in the well body 101 is detected by the flow rate detection module 206. , the water flow velocity is sensed by the flow velocity detection head 209, and the detected water flow information is transmitted to the flow velocity detection module 206 through the waterproof connection line 208. The flow velocity detection module 206 transmits the water flow velocity information to the external related equipment in real time through the wireless connection module. When the water flow velocity is detected to be too slow, the external connection equipment will issue an alarm to remind the water flow abnormality. By setting the flow velocity detection module 206 on the manhole cover, the water flow condition inside the well body 101 can be detected in real time, and there is no need to frequently open the manhole cover assembly 2 to check the flow velocity, which is more convenient and quick. After receiving the abnormal water flow velocity, the staff excavates and opens the manhole cover assembly 2. The impurity particles deposited in the well body 101 are cleaned by the cleaning assembly 3, and the electric push rod 3 is controlled by the telescopic cylinder 303. 02 moves up and down, so that the electric push rod 302 drives the filter plate 301 to move upward to push the impurity particles to the wellhead for cleaning. By setting the cleaning component 3, the impurity particles deposited at the bottom of the well can be automatically pushed upward, so as to facilitate cleaning and avoid time-consuming and labor-intensive manual operation. The sludge will pass through the filter plate 301 and remain at the bottom of the well body 101. The sludge is then discharged through the sewage pipe 105. The pressure is adjusted to a suitable size through the pressure controller on the control valve 106 outside the sewage pipe 105. The control valve 106 is closed after all the sludge is discharged by using the internal and external pressure difference. By setting a pressure controller on the control valve 106 outside the sewage pipe 105, all the sludge can be discharged from the sewage pipe 105 by changing the pressure, so that the cleaning is more thorough. After the final dredging is completed, the manhole cover assembly 2 is covered so that the sealing ring 203 at the lower end of the cover body 201 fits tightly with the upper end of the well body 101, and the block 202 and the limit column 204 limit the cover body 201 from the inside and outside respectively, and then the inspection well body and related structures are buried with soil to restore them to their original state. By setting the block 202 to be connected with the inside of the well body 101 by snapping, and by setting the limit column 204 to be connected with the outside of the well body 101 by snapping, a double limit effect can be achieved, so that the cover body 201 is not easy to slide or deflect. Under the mutual cooperation of the flow rate detection module 206 and the cleaning assembly 3, timely processing can be carried out when blockage occurs inside the well body 101, and it is faster and more efficient through automatic pushing.This can greatly improve work efficiency.

[0038] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
