Description

Technical Field

[0001] The invention relates to the technical field of groundwater investigation, and in particular to a well-washing device and a well-washing method for a groundwater environment monitoring well. Background Art

[0002] Groundwater environment monitoring wells (hereinafter referred to as "monitoring wells") are water quality monitoring wells established to accurately grasp the groundwater environment quality status and the dynamic distribution changes of pollutants in groundwater bodies. In the construction of monitoring wells, well washing is a very important step after the completion of the monitoring wells. The purpose of well washing is to clean up the sediment and other sediments generated during the well construction process, so that the water pumped out of the monitoring wells is clear and transparent, and to ensure the accuracy of the monitoring results.

[0003] At present, common well-cleaning equipment includes bele tubes, submersible pumps, etc. When using bele tubes to clean wells, it is difficult to stir up the sediment in the well, and it is impossible to thoroughly clean the bottom of the well. It also requires multiple times of dropping, salvaging, and pouring out the accumulated water in the tube, and the efficiency of well-cleaning is very low. Submersible pumps require an external power supply, which is expensive, and the heating of the motor will also affect the water quality. In addition, a large amount of sediment will wear the impeller and gasket of the pump during the extraction process, resulting in a high equipment failure rate and inconvenient on-site maintenance. Summary of the invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a groundwater environment monitoring well washing device to solve the problems of traditional well washing equipment being difficult to clean the well, low cleaning efficiency and / or high cost.

[0005] The present invention also provides a well washing method using the above-mentioned groundwater environment monitoring well washing device.

[0006] A well-washing device for a groundwater environment monitoring well according to an embodiment of the first aspect of the present invention comprises: a pipeline assembly, wherein the pipeline assembly comprises a rigid pipe having a first water storage channel, and a drainage pipe having a second water storage channel, one end of the rigid pipe is connected to one end of the drainage pipe, and the first water storage channel is communicated with the second water storage channel; a check valve, wherein the check valve is arranged at an end of the rigid pipe away from the drainage pipe, the check valve comprises a valve body and a valve core, the valve body is provided with an inner cavity having an inlet and an outlet, the outlet is communicated with the first water storage channel, the valve core is arranged inside the inner cavity, and cooperates with the inlet to open and close, water flowing from the inlet toward the outlet can flush the valve core and flow into the first water storage channel through the outlet, and water flowing in the direction from the outlet to the inlet can prompt the valve core to close the inlet; and a stripping bucket, wherein the stripping bucket is fixedly connected to the check valve.

[0007] The groundwater environment monitoring well washing device according to the embodiment of the present invention has at least the following technical effects:

[0008] When the above-mentioned groundwater environment monitoring well washing device is used for well washing, it is only necessary to repeatedly lift the rigid pipe up and down to complete the cleaning of the well. Compared with using the traditional Belle pipe to clean the well, the well can be cleaned more thoroughly and the well washing efficiency is higher. In addition, when the above-mentioned groundwater environment monitoring well washing device is used for well washing, there is no need to use power supply, pump and other electrical appliances, and the cost is low.

[0009] It should be further explained that the background technology mentions the method of using a Beyler tube to clean the well. When the Beyler tube was first designed, its original intention was to take well water for water testing. Therefore, using the Beyler tube to clean the well requires multiple times of dropping, fishing, and pouring out the accumulated water in the tube, and the efficiency of well cleaning is very low. In addition, since the original design of the Beyler tube was not for cleaning the well, but for taking water, the part of the Beyler tube that is manually held by hand is designed to be a flexible structure. It is impossible to manually apply force to the Beyler tube to stir the turbid water in the well, and it is impossible to accurately control the Beyler tube under the well, resulting in the failure to thoroughly clean the bottom of the well when using the Beyler tube to clean the well. When using the groundwater environment monitoring well cleaning device of the present application to clean the well, you can hold the rigid tube by hand to stir the well water, use the stripping bucket to strip the sludge on the well wall, and you only need to repeatedly lift the rigid tube up and down to complete the cleaning of the well, which can clean the well more thoroughly and the well cleaning efficiency is higher.

[0015] According to some embodiments of the present invention, the stripping bucket is a rigid component.

[0016] According to a second aspect of the present invention, a well washing method using the well washing device for monitoring a groundwater environment as described above comprises:

[0017] Preparation step: placing the end of the drainage pipe away from the rigid pipe on the ground, and placing the rigid pipe into the well, so that the check valve extends to the bottom of the well and is immersed in the well water; wherein, after the check valve extends to the bottom of the well and is immersed in the well water, the valve core can be flushed open by the turbid water in the well, and the turbid water in the well will flow into the first water storage channel through the outlet;

[0018] The step of lifting the tube upwards: holding the end of the rigid tube close to the drainage tube, and lifting the rigid tube upwards, so that the valve core is closed under the gravity of the turbid water in the first water storage channel and / or the inner cavity; wherein after the step of lifting the tube upwards, turbid water will remain in the first water storage channel and / or the inner cavity;

[0019] The step of lowering the tube downwards: holding the rigid tube and lowering the rigid tube downwards so that the check valve extends to the bottom of the well and is submerged in the well water; wherein, after the step of lowering the tube downwards is performed, the valve core can be flushed open by the turbid water in the well, and the turbid water in the well will flow into the first water storage channel through the outlet;

[0020] Repeatedly perform the steps of: repeatedly performing the step of lifting the tube upward and the step of lowering the tube downward.

[0021] The well washing method according to the embodiment of the present invention has at least the following technical effects:

Compared with using the traditional Belle pipe to clean the well, the well can be cleaned more thoroughly and the well washing efficiency is higher. In addition, when the above-mentioned groundwater environment monitoring well washing device is used for well washing, there is no need to use power supply, pump and other electrical appliances, and the cost is low.

[0036] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] like Figure 1 As shown, an embodiment relates to a groundwater environment monitoring well washing device, which includes a pipeline assembly 100, a check valve 200 and a stripping bucket 300.

[0038] The pipeline assembly 100 includes a rigid tube 110 having a first water storage channel 111, and a drainage tube 120 having a second water storage channel 121. One end of the rigid tube 110 is connected to one end of the drainage tube 120, and the first water storage channel 111 is communicated with the second water storage channel 121. The check valve 200 is arranged at one end of the rigid tube 110 away from the drainage tube 120. The check valve 200 includes a valve body 210 and a valve core 220. The valve body 210 is provided with an inner cavity 211 having an inlet and an outlet. The outlet of 211 is connected to the first water storage channel 111, and the valve core 220 is arranged inside the inner cavity 211 and cooperates with the opening and closing of the inlet of the inner cavity 211. Water flowing from the inlet of the inner cavity 211 toward the outlet of the inner cavity 211 can flush the valve core 220 and flow into the first water storage channel 111 through the outlet of the inner cavity 211. Water flowing in the direction from the outlet of the inner cavity 211 to the inlet of the inner cavity 211 can prompt the valve core 220 to close the inlet of the inner cavity 211. The stripping bucket 300 is fixedly connected to the check valve 200.

[0039] like Figure 2 , Figure 3 As shown, when the end of the rigid tube 110 away from the drainage tube 120 is placed at the bottom of the well 10, and the check valve 200 is submerged in the well water, the part of the rigid tube 110 close to the drainage tube 120 can be used for hand holding, and the rigid tube 110 can be operated and moved when being held. When the end of the rigid tube 110 away from the drainage tube 120 is placed at the bottom of the well 10, the stripping bucket 300 can contact the sediments that have sunk to the bottom. When the rigid tube 110 is shaken, the rigid tube 110 can rely on the stripping bucket 300 to break up the sediments, thereby facilitating the sediments to enter the groundwater environment monitoring well washing device with the water body. In addition, the stripping bucket 300 can also contact the pollutants on the side wall of the well 10, and strip the pollutants on the wall of the well 10, and completely remove the sediments in the well 10.

[0040] Combination Figures 1 to 3 The specific method of using the above-mentioned groundwater environment monitoring well washing device is as follows:

[0041] 1. Preparation steps for installation: Place the end of the drainage tube 120 away from the rigid tube 110 on the ground, and place the rigid tube 110 into the well 10 so that the check valve 200 extends to the bottom of the well 10 and is submerged in the well water; wherein, after the check valve 200 extends to the bottom of the well 10 and is submerged in the well water, the valve core 220 can be flushed open by the turbid water in the well 10, and the turbid water in the well 10 will flow into the first water storage channel 111 through the outlet of the inner cavity 211.

[0042] 2. Stirring and stripping step: Hold the rigid tube 110 and move the rigid tube 110 so that the stripping bucket 300 strips off the debris attached to the well wall or stirs up the sludge deposited at the bottom of the well. Specifically, hold the rigid tube 110 close to one end of the drainage tube 120 and apply force to the rigid tube 110, use the stripping bucket 300, the check valve 200 and the part of the rigid tube 110 submerged in the water to stir the bottom of the well, stir up the sludge at the bottom of the well, and use the stripping bucket 300 to strip the mud skin on the well wall.

[0043] 3. The step of lifting the tube upward: hold the rigid tube 110 and lift it upward so that the valve core 220 is closed under the gravity of the turbid water in the first water storage channel 111 and / or the inner cavity 211; wherein, after the step of lifting the tube upward is performed, turbid water will remain in the first water storage channel 111 and / or the inner cavity 211.

[0044] 4. Step of lowering the tube downward: Hold the rigid tube 110 close to one end of the drainage tube 120, and lower the rigid tube 110 downward so that the check valve 200 extends to the bottom of the well 10 and is submerged in the well water; wherein, after completing the step of lowering the tube downward, the valve core 220 can be flushed open by the turbid water in the well 10, and the turbid water in the well 10 will flow into the first water storage channel 111 through the outlet.

[0045] 5. Repeatedly execute steps: Repeat the above-mentioned steps of lifting the pipe upward and lowering the pipe downward; in other words, the well washing device for the groundwater environment monitoring well continuously moves up and down in the well 10 under manual operation, the check valve 200 opens and closes, and the turbid water and the silt in the turbid water are continuously discharged to the outside through the rigid pipe 110 and the drainage pipe 120 under the action of inertia until the pumped water becomes clear and transparent.

[0046] It should be noted that when the rigid tube 110 is quickly lifted, the water body will be subjected to an upward force and move upward; if the rigid tube 110 is then pushed down with force, the water body will still move upward due to inertia, and this process can be repeated to continuously pump out the turbid water and silt in the well 10.

[0047] In the above-mentioned groundwater environment monitoring well washing device, the rigid pipe 110 extends into the well 10, and the operator holds the rigid pipe 110 to facilitate applying force to stir the water in the well 10 or change the position of the check valve 200 in the well 10. The drainage pipe 120 is used to be placed on the ground to drain the turbid water and silt in the well 10 to a preset position (such as a turbid water recovery tank or a sewer) to prevent the turbid water and silt from flowing around and affecting the surrounding environment. The check valve 200 can open or close automatically by relying on the flow of water and gravity, and can prevent the turbid water and silt in the first water storage channel 111 and / or the second water storage channel 121 from flowing back. The stripping bucket can 300 stir the silt at the bottom of the well and strip the mud skin on the well wall. When the well is cleaned by the above-mentioned groundwater environment monitoring well cleaning device, the well 10 can be cleaned by repeatedly lifting the rigid pipe 110 up and down. Compared with the use of the traditional Belle pipe to clean the well, the well can be cleaned more thoroughly and the well cleaning efficiency is higher. In addition, when the well is cleaned by the above-mentioned groundwater environment monitoring well cleaning device, there is no need to use power supply, pump and other electrical appliances, and the cost is low.

[0048] It should be further explained that the background technology mentions the method of using a Beyler tube to clean the well. When the Beyler tube was first designed, its original intention was to take well water for water testing. Therefore, using the Beyler tube to clean the well requires multiple times of dropping, fishing, and pouring out the accumulated water in the tube, and the efficiency of well cleaning is very low. In addition, since the original design of the Beyler tube was not for cleaning the well, but for taking water, the part of the Beyler tube that is manually held is designed to be a flexible structure. It is impossible to manually apply force to the Beyler tube to stir the turbid water in the well, and it is also impossible to accurately control the Beyler tube under the well, resulting in the failure to thoroughly clean the bottom of the well when using the Beyler tube to clean the well. When using the groundwater environment monitoring well cleaning device of the present application to clean the well, the rigid tube 110 can be held by hand to stir the well water, and the sludge on the well wall can be stripped off by the stripping bucket 300, and the wellway can be cleaned only by repeatedly lifting the rigid tube 110 up and down, which can clean the wellway more thoroughly and achieve higher well cleaning efficiency.

[0049] Optionally, the material of the rigid tube 110 may be a stainless steel tube, a seamless steel tube or a plastic tube, etc. The rigid tube 110 is wear-resistant and has good pressure bearing capacity, and can ensure the stability of the overall structure.

[0050] In one embodiment, the rigid pipe 110 includes multiple rigid short pipes connected end to end, and the length of the rigid pipe can be adjusted by the multiple rigid short pipes. In this way, the overall length of the rigid pipe can be adjusted according to the depth of the well 10 so that an operator standing on the ground can hold the rigid pipe 110 by hand.

[0051] Specifically, among two adjacent rigid short tubes, one rigid short tube is sleeved outside the other rigid short tube, and the two are slidably matched, so that the length of the rigid tube can be adjusted through multiple sections of rigid short tubes.

[0052] In one embodiment, the drainage pipe 120 is a flexible pipe. The flexible pipe can reduce the noise generated by the water flowing into the second water storage channel 121, and the flexible pipe has strong anti-bending and stretching deformation capabilities, and can discharge the pumped turbid water and silt out of the well 10 in a directional manner to prevent the turbid water and silt from spreading everywhere.

[0053] Furthermore, the rigid tube 110 is threadedly connected to the drainage tube 120 for easy replacement.

[0054] Furthermore, a sealing ring or a polytetrafluoroethylene tape is provided at the threaded connection between the rigid tube 110 and the drainage tube 120, so as to provide good sealing performance.

[0055] In one embodiment, the check valve 200 is disposed below the bottom of the rigid tube 110, the valve body 210 and the rigid tube 110 are threadedly connected, and a sealing ring or polytetrafluoroethylene tape is disposed at the threaded connection between the valve body 210 and the rigid tube 110. In case of a malfunction, the check valve 200 can be easily replaced and repaired, and the possibility of leakage of the check valve 200 can be eliminated.

[0056] In other embodiments, the check valve 200 may also be disposed in the rigid tube 110 and located at the bottom end of the rigid tube 110 .

[0057] Furthermore, the valve core 220 is rotatably connected to the valve body 210. In this way, the valve core 220 can be opened or closed by the flow of water and gravity.

[0058] In one embodiment, the stripping bucket 300 is a funnel structure, and the stripping bucket 300 has a large end and a small end opposite to the large end. The stripping bucket is arranged on the side of the check valve 200 away from the rigid pipe 110, and the small end is arranged opposite to the inlet of the inner cavity 211, and the small end is closer to the inlet of the inner cavity 211 than the large end. In this way, the contact area between the stripping bucket and the sediment at the bottom can be increased, and the well washing efficiency can be improved.

[0059] It should be noted that the small-mouth end refers to the end with a smaller diameter among the two ends of the stripping bucket 300 ; the large-mouth end refers to the end with a larger diameter among the two ends of the stripping bucket 300 .

[0060] More specifically, the stripping bucket 300 is a rigid component, has strong pressure bearing capacity, and is not easily damaged.

[0061] One embodiment also relates to a well washing method using the well washing device for monitoring a groundwater environment as described above, comprising:

[0062] 1. Preparation steps for installation: Place the end of the drainage tube 120 away from the rigid tube 110 on the ground, and place the rigid tube 110 into the well 10 so that the check valve 200 extends to the bottom of the well 10 and is submerged in the well water; wherein, after the check valve 200 extends to the bottom of the well 10 and is submerged in the well water, the valve core 220 can be flushed open by the turbid water in the well 10, and the turbid water in the well 10 will flow into the first water storage channel 111 through the outlet of the inner cavity 211.

[0063] 2. Stirring and stripping step: Hold the rigid tube 110 and move it so that the stripping bucket 300 strips off the pollutants attached to the well wall or stirs up the sludge deposited at the bottom of the well. Specifically, hold the rigid tube 110 and apply force to it, and use the stripping bucket 300, the check valve 200 and the part of the rigid tube 110 submerged in the water to stir the bottom of the well, stir up the sludge at the bottom of the well, and strip the mud skin on the well wall at the same time.

[0064] 3. The step of lifting the tube upward: hold the rigid tube 110 close to one end of the drainage tube 120, and lift the rigid tube 110 upward so that the valve core 220 is closed under the gravity of the turbid water in the first water storage channel 111 and / or the inner cavity 211; wherein, after performing the step of lifting the tube upward, turbid water will remain in the first water storage channel 111 and / or the inner cavity 211.

[0065] 4. Tube lowering step: Hold the rigid tube 110 and lower it downwards so that the check valve 200 extends into the bottom of the well 10 and is submerged in the well water; after the tube lowering step is completed, the valve core 220 can be flushed open by the turbid water in the well 10, and the turbid water in the well 10 will flow into the first water storage channel 111 through the outlet;

[0066] 5. Repeat the steps: Repeat the steps of lifting the tube upward and lowering the tube downward.

[0067] When the well-cleaning device for monitoring the underground water environment is used to clean the well, the well cleaning can be completed by repeatedly lifting the rigid pipe 110 up and down. Compared with the use of the traditional Belle pipe to clean the well, the well can be cleaned more thoroughly and the well cleaning efficiency is higher. In addition, when the well-cleaning device for monitoring the underground water environment is used to clean the well, there is no need to use power supply, pump and other electrical appliances, and the cost is low.
