[0024] Start the frequency conversion pump to wash the well.

[0025] The beneficial effects of the present invention are:

[0026] 1. By controlling several groups of lifting components to drive the pipeline mechanism to slowly descend in the monitoring well until the pumping mechanism enters the groundwater, the attitude sensor can monitor the state of the connecting plate and keep the pipeline mechanism vertical by individually controlling several groups of lifting components, so that the lifting adjustment mechanism can drive the pipeline mechanism to descend in monitoring wells of different sizes, and the pumping mechanism will not be affected by the flow of groundwater after entering the groundwater. At the same time, the monitoring module can monitor the water flow, so that the variable frequency pump can adjust the suction force in real time to reduce the disturbance to the groundwater, which not only improves the compatibility of the well washing device, but also improves the use effect of the well washing device.

[0027] 2. By controlling several groups of second electric push rods to drive the lifting ring to descend, several groups of adjusting rods are expanded to the side under the action of several groups of connecting rods, so that several groups of folding plates can be expanded. At the same time, the distance sensor on each group of adjusting rods can monitor the horizontal position of the anti-falling mechanism in the monitoring well, and then control the lifting and adjusting mechanism to adjust the horizontal position of the pipeline mechanism to keep the anti-falling mechanism in the center state, so that the fallen objects on the inner wall of the monitoring well cannot fall into the groundwater, thereby improving the anti-interference performance of the well washing device.

DETAILED DESCRIPTION

[0041] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] The embodiment of the present invention provides a low-disturbance rapid well washing device for organic pollutants in groundwater, comprising a pipeline mechanism 1. For example, Figure 1 As shown, a lifting and adjusting mechanism 2 is provided on the outer wall of the pipeline mechanism 1; a falling object prevention mechanism 3 is provided on the outer wall of the pipeline mechanism 1; the falling object prevention mechanism 3 is located below the lifting and adjusting mechanism 2; a pumping mechanism 4 is connected to the bottom of the pipeline mechanism 1; and a connecting hose 5 is connected to the top of the pipeline mechanism 1.

[0043] When washing the well, the end of the connecting hose 5 away from the pipeline mechanism 1 is connected to the output end of the frequency conversion pump, and then the pipeline mechanism 1 is placed at the wellhead of the detection well, and then the lifting and adjusting mechanism 2 is controlled to drive the pipeline mechanism 1 to descend from the wellhead until the pumping mechanism 4 enters the groundwater. At the same time, the anti-falling mechanism 3 prevents the fallen objects on the inner wall of the monitoring well from falling into the groundwater and causing disturbance during the lifting and working process of the pipeline mechanism 1, and then the frequency conversion pump is controlled to pump the groundwater through the connecting hose 5, the pipeline mechanism 1 and the pumping mechanism 4 to wash the well until the pumped water is clear and transparent, and then the water quality is monitored.

[0044] For example, Figure 2 As shown, the pipeline mechanism 1 includes a rigid pipeline 101; a limiting groove 102 is provided on the outer wall of the rigid pipeline 101; a connecting groove 103 is provided on the top of the rigid pipeline 101; a connecting pipe 104 is provided at the bottom of the rigid pipeline 101; and a sealing airbag 105 is sleeved on the outer wall of the connecting pipe 104.

[0045] When the monitoring well reaches a corresponding depth, the fluid resistance generated by the corresponding length of the connecting hose 5 will cause overload damage to the variable frequency pump. At this time, the length of the connecting hose 5 can be reduced by splicing the pipeline mechanism 1, and the connecting pipe 104 at the bottom of the upper rigid pipeline 101 enters the connecting groove 103 at the top of the lower rigid pipeline 101, and then the sealing airbag 105 is controlled to expand to make the connection between the two groups of rigid pipelines 101 sealed. After splicing a corresponding number of rigid pipelines 101, the fluid resistance during pumping is reduced by increasing the length of the hard pipe and reducing the length of the hose, thereby avoiding overload damage to the pump body and improving the use effect of the well washing device.

[0046] For example, Figure 3 , Figure 4 and Figure 5As shown, the lifting and adjusting mechanism 2 includes a connecting plate 201; a plurality of lifting components 202 are arranged in a circular array on the outer wall of the connecting plate 201; a movable through groove 203 is opened on the connecting plate 201; a group of slide grooves 204 are respectively opened on the inner walls of the four sides of the movable through groove 203; a group of first electric push rods 205 are slidably connected in each group of the slide grooves 204; a group of limit plates 206 are transmission-connected to the output end of each group of the first electric push rods 205; each group of the limit plates 206 is movably inserted into the limit groove 102; four groups of the limit plates 206 are combined to form a circular ring mechanism; a posture sensor 207 is provided on the top of the connecting plate 201.

[0047] The lifting assembly 202 includes a connecting block 2021; the connecting block 2021 is installed on the outer wall of the connecting plate 201; the end of the connecting block 2021 away from the connecting plate 201 is hinged with a supporting frame plate 2022; a first motor 2023 is provided on a side wall of the connecting block 2021; the output end of the first motor 2023 is transmission-connected with the supporting frame plate 2022; a mounting groove 2025 is provided at the end of the supporting frame plate 2022 away from the connecting block 2021; a walking track 2024 is provided in the mounting groove 2025; two groups of second motors 2026 are provided on a side wall of the supporting frame plate 2022; the output end of each group of the second motors 2026 extends into the mounting groove 2025, and is transmission-connected with a group of transmission rollers 2027; the two groups of the transmission rollers 2027 are transmission-connected with the walking track 2024.

[0048] When performing the well washing operation, the pipeline mechanism 1 is placed on the wellhead of the monitoring well. At this time, the four groups of lifting components 202 are in contact with the wellhead to prevent the pipeline mechanism 1 from falling into the monitoring well. Then, several groups of first motors 2023 are controlled to drive several groups of support frame plates 2022 to rotate and adjust the angle, so that the pipeline mechanism 1 can enter the monitoring well. Then, several groups of second motors 2026 are controlled to drive several groups of walking tracks 2024 to rotate through corresponding transmission rollers 2027, so that the pipeline mechanism 1 can slowly descend in the monitoring well until the pumping mechanism 4 enters the groundwater. The attitude sensor 207 can monitor the state of the connecting plate 201 and keep the pipeline mechanism 1 vertical by controlling several groups of lifting components 202 separately. When the pipeline mechanism 1 is spliced, the horizontal position of the pipeline mechanism 1 can be adjusted by controlling the extension and retraction of the four groups of first electric push rods 205 to perform docking work, so that the lifting and adjusting mechanism 2 can drive the pipeline mechanism 1 to descend in monitoring wells of different sizes, and the pumping mechanism 4 will not be affected by the flow of groundwater after entering the groundwater, which not only improves the compatibility of the well washing device, but also improves the accuracy of the monitoring results.

[0049] For example, Figure 6As shown, the anti-falling object mechanism 3 includes a connecting ring 301; the connecting ring 301 is sleeved on the outer wall of the pipeline mechanism 1; a plurality of groups of adjusting rods 302 are hingedly connected in a circular array at the top edge of the connecting ring 301; a group of distance sensors 303 are provided at the end of each group of adjusting rods 302 away from the connecting ring 301; a group of folding plates 304 are provided between two adjacent groups of adjusting rods 302; a plurality of groups of second electric push rods 305 are provided on the top of the connecting ring 301; a lifting ring 306 is transmission-connected to the output end of the plurality of groups of the second electric push rods 305; a plurality of groups of connecting rods 307 are hingedly connected in a circular array on the outer wall of the lifting ring 306; the end of each group of connecting rods 307 away from the lifting ring 306 is hinged to the corresponding group of adjusting rods 302.

[0050] When performing well washing, by controlling several groups of second electric push rods 305 to drive the lifting ring 306 to descend, several groups of adjusting rods 302 are expanded to the side under the action of several groups of connecting rods 307, so that several groups of folding plates 304 can be expanded. At the same time, the distance sensor 303 on each group of adjusting rods 302 can monitor the horizontal position of the anti-falling mechanism 3 in the monitoring well, and then control the lifting and adjusting mechanism 2 to adjust the horizontal position of the pipeline mechanism 1 to keep the anti-falling mechanism 3 in the center state, so that the fallen objects on the inner wall of the monitoring well cannot fall into the groundwater, thereby improving the anti-interference performance of the well washing device.

[0051] For example, Figure 7 and Figure 8 As shown, the pumping mechanism 4 includes a shell 401; a connecting hole 402 is opened at the bottom of the shell 401; the connecting hole 402 is connected with the connecting pipe 104; a monitoring module 404 is provided on the bottom side wall of the shell 401; a pumping chamber 406 is provided in the shell 401; a plurality of water inlet holes 403 are evenly distributed on the inner wall of the pumping chamber 406; a connecting chamber 405 is provided in the shell 401; the connecting chamber 405 is connected with the connecting hole 402; a liquid level sensor 407 is provided at the top center of the pumping chamber 406; an anti-disturbance ring 408 is sleeved on the inner wall of the pumping chamber 406; a plurality of pumping holes 409 are distributed in a circular array on the inner wall of the pumping chamber 406 close to the anti-disturbance ring 408; a plurality of groups of pumping holes 409 are connected with the connecting chamber 405.

[0052] When washing the well, the pumping mechanism 4 enters the groundwater, and the groundwater enters the pumping chamber 406 through several groups of water inlet holes 403. The liquid level sensor 407 can monitor the liquid level height in the pumping chamber 406 to ensure that the liquid level is higher than several groups of pumping holes 409. Then the frequency conversion pump connects the hose 5 and the pipeline mechanism 1 to enable several groups of pumping holes 409 to perform pumping work. This can not only avoid the problem of blockage caused by foreign matter in the water, but also enable the groundwater to be evenly sucked through several groups of water inlet holes 403, reducing the disturbance to the groundwater. The monitoring module 404 can monitor the flow of groundwater and reduce the disturbance to the groundwater by controlling the power of the frequency conversion pump.

[0053] By controlling several groups of lifting components 202 to drive the pipeline mechanism 1 to slowly descend in the monitoring well until the pumping mechanism 4 enters the groundwater, the posture sensor 207 can monitor the state of the connecting plate 201, and by individually controlling several groups of lifting components 202, the pipeline mechanism 1 can be kept vertical, so that the lifting adjustment mechanism 2 can drive the pipeline mechanism 1 to descend in monitoring wells of different sizes, and the pumping mechanism 4 will not be affected by the flow of groundwater after entering the groundwater. At the same time, the monitoring module 404 can monitor the water flow, so that the variable frequency pump can adjust the suction force in real time to reduce the disturbance to the groundwater, which not only improves the compatibility of the well washing device, but also improves the use effect of the well washing device.

[0054] By controlling several groups of second electric push rods 305 to drive the lifting ring 306 to descend, several groups of adjusting rods 302 are expanded to the side under the action of several groups of connecting rods 307, so that several groups of folding plates 304 can be expanded. At the same time, the distance sensor 303 on each group of adjusting rods 302 can monitor the horizontal position of the anti-falling object mechanism 3 in the monitoring well, and then control the lifting and adjusting mechanism 2 to adjust the horizontal position of the pipeline mechanism 1 to keep the anti-falling object mechanism 3 in the center state, so that the fallen objects on the inner wall of the monitoring well cannot fall into the groundwater, thereby improving the anti-interference performance of the well washing device.

[0055] When the monitoring well reaches a corresponding depth, the fluid resistance generated by the corresponding length of the connecting hose 5 will cause overload damage to the variable frequency pump. At this time, the length of the connecting hose 5 can be reduced by splicing the pipeline mechanism 1, and the connecting pipe 104 at the bottom of the upper rigid pipeline 101 enters the connecting groove 103 at the top of the lower rigid pipeline 101, and then the sealing airbag 105 is controlled to expand to make the connection between the two groups of rigid pipelines 101 sealed. After splicing a corresponding number of rigid pipelines 101, the fluid resistance during pumping is reduced by increasing the length of the hard pipe and reducing the length of the hose, thereby avoiding overload damage to the pump body and improving the use effect of the well washing device.

[0056] When washing the well, the pumping mechanism 4 enters the groundwater, and the groundwater enters the pumping chamber 406 through several groups of water inlet holes 403. The liquid level sensor 407 can monitor the liquid level height in the pumping chamber 406 to ensure that the liquid level is higher than several groups of pumping holes 409. Then the frequency conversion pump connects the hose 5 and the pipeline mechanism 1 to enable several groups of pumping holes 409 to perform pumping work. This not only avoids the problem of blockage caused by foreign matter in the water, but also allows the groundwater to be evenly sucked through several groups of water inlet holes 403, reducing the disturbance to the groundwater.

[0057] Based on the above-mentioned low-disturbance rapid well-washing device for groundwater organic pollutants, the embodiment of the present invention further proposes a method for using the low-disturbance rapid well-washing device for groundwater organic pollutants. Exemplarily, the method includes:

[0058] Placing the pipeline mechanism at the wellhead of the monitoring well so that the lifting and adjusting assembly is supported at the wellhead;

[0059] Control the four lifting components to adjust the angles so that the pipeline mechanism enters the monitoring well;

[0060] Control the deployment of the falling object prevention mechanism;

[0062] Connect the connecting hose to the output end of the variable frequency pump;

[0063] Start the frequency conversion pump to wash the well.

[0064] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein; and these modifications or substitutions do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
