A vibrating mechanism 9 is installed near the opening at the top of the cleaning water tank 1 and cooperates with the flushing structure 8 for transmission. The dredging pump body 6 and the top opening and the through-notch 13 of the cleaning water tank 1 are on the same vertical center line, and the cleaning water tank 1 is made of a transparent acrylic plate.

[0030] Specifically, the user grasps the push handle 11 to push the device, and moves it to the work site by adjusting the universal brake wheel 4 installed on the moving mechanism 3, so that it is convenient to carry, and the dredging pump body 6 can be placed in the cleaning water tank 1 for protection. When the groundwater environment monitoring wellhead is large and the device is difficult to move to the top, the telescopic structure can be used to adjust the length, so that it is convenient to move to the top of the groundwater environment monitoring well for dredging work;

[0031] During operation, the dredging pump body 6 is driven by the lifting structure 7 to enter the bottom of the groundwater environment monitoring well to extract silt. After the dredging pump body 6 is completed, the dredging pump body 6 is raised to the cleaning water tank 1, and the surface of the dredging pump body 6 is rinsed by the flushing structure 8 to keep its surface relatively clean. The cleaned sewage is collected at the bottom of the cleaning water tank 1. At the same time, the water sprayed by the flushing structure 8 impacts the vibration mechanism 9 to drive the rotation, contact and collide with the dredging pump body 6 to generate vibration. The dredging pump body 6 is struck and vibrated multiple times during the rising process, and the silt and gravel remaining in the dredging pump body 6 are effectively discharged. When the dredging pump body 6 rises to the lifting structure 7, the sewage in the cleaning water tank 1 is filtered by driving the filtering mechanism 5, and then the dredging pump body 6 is lowered into the cleaning water tank 1 again to extract the filtered water, and the inside and outside of the dredging pump body 6 and the water pipe belt 2 are cleaned, thereby realizing all-round cleaning of the dredging pump body 6, without manual cleaning of the dredging pump body 6, which is relatively convenient.

[0032] In this embodiment, Figure 6 It is given that the lifting structure 7 includes a mounting frame 71 fixed at the opening position of the cleaning water tank 1, a connecting plate 72 is fixed to the top opening of the mounting frame 71, a guiding double wheel 73 is fixed to the middle of the connecting plate 72, a mounting seat 77 is fixed to one side of the top of the mounting frame 71, the internal rotating shaft of the mounting seat 77 is connected to a double winding disk 76, a reduction motor 74 is fixed to the side end of the mounting seat 77, the output shaft of the reduction motor 74 passes through the mounting seat 77 and is transmission-connected to the double winding disk 76, the double winding disk 76 is wound with two groups of steel cables 75, the two groups of steel cables 75 are guided by the guiding double wheels 73 and fixedly connected to the dredging pump body 6, and one group of steel cables 75 is wrapped with electric wires and electrically connected to the dredging pump body 6, and the reduction motor 74 and the dredging pump body 6 are electrically connected to the controller 12 through electric wires.

[0033] Specifically, the controller 12 drives the reduction motor 74 to work, driving the double winding drum 76 to unwind the steel cable 75. The steel cable 75 connected to the dredging pump body 6 is guided by the double guide wheels, so that the dredging pump slowly descends through the through slot 13 into the groundwater environment monitoring well. At the same time, the auxiliary water pipe belt 2 follows downward until the bottom of the well is reached, and then the reduction motor 74 is controlled to stop working, and then the dredging pump body 6 is energized to extract the silt at the bottom of the groundwater environment monitoring wellhead and output it to the outside through the water pipe belt 2. After dredging is completed, the reduction motor 74 is controlled to reverse, driving the double winding drum 76 to rewind the steel cable 75, and the dredging pump body 6 rises back to its position.

[0034] In this embodiment, Figure 7-8 It is given that the adjusting and moving mechanism 3 includes a base 31 fixedly connected to the cleaning water tank 1, a slot is opened at the side end of the base 31 and is connected to the through slot 13, a rubber ring gasket is fixed at the connection between the slot and the through slot 13, a sealing plate 131 is inserted into the slot for sealing, the sealing plate 131 is provided with pull grooves 132 on the outside, and telescopic structures are provided at the four corners of the base 31.

[0035] Specifically, when performing dredging work, grasp the pull groove 132 of the sealing plate 131 to pull the sealing plate 131 out of the bottom plate, exposing the through slot 13, so that the dredging pump body 6 descends to the bottom of the groundwater environment monitoring well. When the dredging pump body 6 rises and enters the water tank for cleaning, the sealing plate 131 is inserted into the base 31 to block the through slot 13, so as to facilitate the collection of sewage during cleaning.

[0036] Among them, the telescopic structure includes telescopic grooves opened at the four corners of the base 31, and a telescopic plate 33 is inserted and connected in each telescopic groove. The universal brake wheel 4 is fixed to the bottom of the telescopic plate 33, and the base 31 is threadedly connected with a locking screw 32 near the telescopic groove. The locking screw 32 thread penetrates into the telescopic groove and abuts against the telescopic plate 33; when the groundwater environment monitoring wellhead is large and difficult to move upward, the length can be adjusted through the telescopic structure, the locking screw 32 can be loosened, the telescopic plate 33 can be pulled out to extend the universal brake wheel 4, and then the locking screw 32 can be tightened again, so that the support range of the rotating shaft base 31 becomes larger, which is convenient for moving to the top of the groundwater environment monitoring well for dredging work.

[0037] Embodiment 2, based on embodiment 1, Figure 2 and Figure 4 It is shown that the flushing structure 8 includes a rectangular tube 82 fixed on the upper part of the cleaning water tank 1 and a high-pressure pump 81 fixed on the outside of the cleaning water tank 1. A plurality of nozzles 83 are evenly fixed on the inner wall of the rectangular tube 82 and are connected to the rectangular tube 82. The input end of the high-pressure pump 81 is connected to an external water source through a hose, and the output end is fixedly connected to the rectangular tube 82 through a hose that penetrates the cleaning water tank 1. The high-pressure pump 81 is electrically connected to the controller 12.

[0038] Specifically, when the dredging pump body 6 rises and enters the water tank, the sealing plate 131 is inserted into the base 31 to seal the through slot 13, and at the same time, the high-pressure pump 81 is controlled to extract clean water and transport it to the rectangular tube 82, and spray it out from multiple nozzles 83. When the dredging pump body 6 passes through the rectangular tube 82, the surface of the dredging pump body 6 is flushed to keep its surface relatively clean, and the cleaned sewage is collected at the bottom of the cleaning water tank 1.

[0039] Among them, the vibrating mechanism 9 is located as a whole inside the rectangular tube 82, and some nozzles 83 of the rectangular tube 82 close to the vibrating mechanism 9 are arranged in the same inclined direction. The sprayed water can impact the transmission fan plate 93 to drive the rotation. At the same time, the water sprayed from some nozzles 83 impacts the vibrating mechanism 9 to rotate, and collides with the dredging pump body 6 to generate vibration. The dredging pump body 6 is hit and vibrated multiple times during the rising process, so as to effectively discharge the silt and gravel remaining in the dredging pump body 6.

[0040] In this embodiment, Figure 5It is given that the vibrating mechanism 9 includes a connecting shaft 91 fixed on the top of the cleaning water tank 1, the bottom of the connecting shaft 91 is rotatably connected to a rotating seat 92, and a plurality of transmission fan plates 93 are equally fixed on the outside of the rotating seat 92, each transmission fan plate 93 is fixedly connected to one end of a spring 94, and a striking ball 95 is fixed to the other end of the spring 94, and the striking ball 95 is in contact with the surface of the dredging pump body 6.

[0041] Specifically, the water is sprayed obliquely on the multiple transmission fan plates 93 connected to the rotating seat 92, causing them to rotate under force. During the rotation, the striking ball 95 follows the selection and, due to inertia, the spring 94 is stretched. The rotating striking ball 95 contacts and collides with the dredging pump body 6 to generate vibration. The dredging pump body 6 is hit and vibrated multiple times during the rising process, thereby effectively discharging the silt and gravel remaining inside the dredging pump body 6.

[0042] Embodiment 3, based on embodiment 1, Figure 3 It is given that the driving and filtering mechanism 5 includes a driving motor 51 and a guide frame 52 fixed on the outside of the cleaning water tank 1, three guide rods 53 and a threaded rod 54 are fixedly installed on the front and rear edges of the inside of the cleaning water tank 1, respectively, the guide frame 52 is movably connected to the three guide rods 53, and is threadedly connected to the threaded rod 54, and a filter cotton 521 is fixed in the middle of the guide frame 52, the output shaft of the driving motor 51 passes through the cleaning water tank 1 and is connected to the threaded rod 54, and the driving motor 51 is electrically connected to the controller 12.

[0043] Specifically, when the dredging pump body 6 rises to the installation frame 71, the reduction motor 74 is controlled to stop working. At this time, the collected sewage does not exceed the driving filter mechanism 5, and then the driving motor 51 is controlled to rotate, driving the threaded rod 54 and the guide frame 52 to transmit. The guide frame 52 is assisted by three guide rods 53 to stably move to the other side of the cleaning water tank 1. During the movement of the guide frame 52, the impurity particles in the sewage are filtered through the filter cotton 521. After moving to the other side of the cleaning water tank 1, the driving motor 51 is controlled to stop working. At this time, the filtered water is relatively clean. The user controls the reduction motor 74 again to drive the dredging pump body 6 to descend to the bottom of the cleaning water tank 1, and then controls the dredging pump body 6 to extract water to clean the inside and outside of the dredging pump body 6 and the water pipe belt 2, thereby realizing all-round cleaning of the dredging pump body 6. There is no need to manually clean the dredging pump body 6, which is relatively convenient.

[0044] Working principle:

[0045] First, the user grasps the push handle 11 to push the device, and moves it to the work site by adjusting the universal brake wheel 4 installed on the moving mechanism 3, so that it is easy to carry, and the dredging pump body 6 can be placed in the cleaning water tank 1 for protection. When the groundwater environment monitoring wellhead is large and the device is difficult to move to the top, the length can be adjusted through the telescopic structure, the locking screw 32 is loosened, and the telescopic plate 33 is pulled out to extend the universal brake wheel 4, and then the locking screw 32 is tightened again, so that the support range of the rotating shaft base 31 becomes larger, which is convenient for moving to the top of the groundwater environment monitoring well for dredging:

[0046] Before the sludge pumping work, the dredging pump body 6 initially rises to the mounting frame 71, the rolled water hose belt 2 is unwound, and passed through the mounting frame 71 to be connected to the output end of the dredging pump body 6, and the user grasps the groove 132 of the sealing plate 131 to pull the sealing plate 131 out of the bottom plate, exposing the through-slot 13;

[0047] The device is connected to a power source, and the controller 12 drives the reduction motor 74 to work, driving the double winding drum 76 to unwind the steel cable 75. The steel cable 75 connected to the dredging pump body 6 is guided by the double guide wheels, so that the dredging pump slowly descends through the through slot 13 into the groundwater environment monitoring well, and the auxiliary water pipe belt 2 follows downward until the bottom of the well is reached, and then the reduction motor 74 is controlled to stop working, and then the dredging pump body 6 is controlled to be powered on, and the sludge at the bottom of the groundwater environment monitoring well is extracted and output to the outside through the water pipe belt 2;

[0048] After the dredging is completed, the reduction motor 74 is controlled to reverse, driving the double winding drum 76 to reel in the steel cable 75. When the dredging pump body 6 rises and enters the water tank, the sealing plate 131 is inserted into the base 31 to block the through slot 13. At the same time, the high-pressure pump 81 is controlled to extract clean water and transport it to the rectangular tube 82, and spray it from multiple nozzles 83. When the dredging pump body 6 passes through the rectangular tube 82, the surface of the dredging pump body 6 is washed to keep its surface relatively clean, and the washed sewage is collected at the bottom of the cleaning water tank 1;

[0049] At the same time, the water sprayed from some nozzles 83 impacts the vibration mechanism 9, and the water sprays obliquely on the multiple transmission fan plates 93 connected to the rotating seat 92, so that it rotates under force. During the rotation, the striking ball 95 follows the selection and is stretched by inertia to extend the spring 94. The rotating striking ball 95 contacts and collides with the dredging pump body 6 to generate vibration. The dredging pump body 6 is struck and vibrated multiple times during the rising process, and the silt and gravel remaining in the dredging pump body 6 are effectively discharged;

[0050] When the dredging pump body 6 rises to the mounting frame 71, the reduction motor 74 is controlled to stop working. At this time, the collected sewage does not exceed the driving filter mechanism 5, and the driving motor 51 is controlled to rotate, driving the threaded rod 54 and the guide frame 52 to transmit. The guide frame 52 is assisted by three guide rods 53 to stably move to the other side of the cleaning water tank 1. During the movement of the guide frame 52, the impurity particles in the sewage are filtered through the filter cotton 521. After moving to the other side of the cleaning water tank 1, the driving motor 51 is controlled to stop working. At this time, the filtered water is relatively clean. The user controls the reduction motor 74 again to drive the dredging pump body 6 to descend to the bottom of the cleaning water tank 1, and then controls the dredging pump body 6 to extract water to clean the inside and outside of the dredging pump body 6 and the water pipe belt 2, thereby realizing all-round cleaning of the dredging pump body 6, without the need for manual cleaning of the dredging pump body 6, which is relatively convenient;

[0051] Finally, the sealing plate 131 is pulled out to expose the through slot 13, and the reduction motor 74 is controlled to drive the dredging pump body 6 to rise into the mounting frame 71, and then the driving motor 51 is controlled to drive the guide frame 52 to return. During the return process, the high-pressure pump 81 is controlled to draw clean water into the rectangular tube 82, and sprayed from multiple nozzles 83 to flush the inside of the cleaning water tank 1. The flushing sewage flows out from the through slot 13, so that the cleaning water tank 1 remains clean.
