Description

Technical Field

[0001] This utility model belongs to the technical field of pump lifting devices, and in particular relates to a pump lifting device for groundwater environmental survey and pumping test. Background Technology

[0002] Pumping tests are the main method for determining aquifer parameters and understanding hydrogeological conditions. By pumping tests, the hydrogeological parameters of the aquifer and the transect are determined. By measuring the well inflow and its relationship with the water level drop, the water-bearing capacity of the aquifer is analyzed and the well's water production capacity is evaluated.

[0003] Currently, pumping tests are still mainly conducted manually. For shallow wells, personnel need to lower the pump into the well themselves using ropes. For deep wells, multiple personnel are needed to lower the pump into the well together using ropes. This not only consumes a lot of human resources and is inefficient, but also makes it difficult for a single person to work.

[0004] Therefore, there is an urgent need to design a pumping device for groundwater environmental investigation and pumping tests to solve the problems mentioned above, such as high human resource consumption, low efficiency, and difficulty in achieving single-person operation.

A hook is provided at the end of the wire rope for the submersible pump to hook.

[0008] Furthermore, the pump lifting frame base includes a first link, a second link, a third link, and a fourth link, which are connected end to end in sequence to form a support frame larger than the wellhead. The upper arm of the pump lifting frame is fixedly connected to the first link.

[0009] Furthermore, the first link, second link, third link, and fourth link are all telescopic rods.

[0010] Furthermore, the first connecting rod includes a first sleeve, with two first core tubes inserted into each end of the first sleeve. The first sleeve has multiple first screw holes, and the first core tubes have multiple second screw holes.

The second sleeve has multiple third screw holes, and the second core tube has multiple fourth screw holes. The overlapping third and fourth screw holes are screwed together by bolts to fix the extension length of the second core tube. The end of the second core tube away from the second sleeve is fixedly connected to the third connecting rod.

[0012] Furthermore, pulleys are installed on the upper arm of the pump lifting frame to guide the wire rope of the winch.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Those skilled in the art will understand that although some embodiments herein include certain features included in other embodiments but not others, combinations of features from different embodiments are intended to be within the scope of this invention and form different embodiments. For example, in the claims, any of the claimed embodiments can be used in any combination.

[0024] The following is a reference to the appendix. Figure 1 To be continued Figure 2 This invention describes a pumping device for groundwater environmental survey and pumping test.

[0025] A pumping device for groundwater environmental survey pumping test, such as Figure 1 As shown, the system includes a pump lifting frame base 1, a pump lifting frame upper arm 2 fixedly connected to the pump lifting frame base 1, a winch 3 installed on the pump lifting frame base 1, and the wire rope of the winch 3 being guided by the pump lifting frame upper arm 2 so that the end of the wire rope is directly above the wellhead 4. The end of the wire rope is equipped with a hook 6 for the submersible pump 5 to be hooked. The winch 3 realizes the lifting and lowering of the submersible pump 5 through the wire rope, which improves the operating efficiency, is easy to operate, is suitable for single-person operation, and reduces the dependence on manpower.

[0026] As a preferred option, such as Figure 2As shown, the pump lifting frame base 1 includes a first connecting rod 101, a second connecting rod 102, a third connecting rod 103, and a fourth connecting rod 104. The first connecting rod 101, the second connecting rod 102, the third connecting rod 103, and the fourth connecting rod 104 are connected end to end in sequence to form a support frame larger than the wellhead 4. The upper arm 2 of the pump lifting frame is fixedly connected to the first connecting rod 101. The support frame design allows the device to be stably placed around the wellhead 4, improving the safety of operation. At the same time, the support frame is larger than the wellhead 4, avoiding the risk of overturning due to the frame being too small.

[0027] Preferably, the first link 101, the second link 102, the third link 103 and the fourth link 104 are all telescopic rods, which can be adjusted according to different wellhead sizes and terrain, making them convenient for transportation and storage and suitable for field operations.

[0028] Preferably, the first connecting rod 101 includes a first sleeve 100, with two first core tubes 200 inserted into each end of the first sleeve 100. The first sleeve 100 has multiple first screw holes 300, and the first core tubes 200 have multiple second screw holes 400. The overlapping first screw holes 300 and second screw holes 400 are screwed together by bolts to fix the extension length of the two first core tubes 200. The midpoint of the first sleeve 100 is fixedly connected to the upper arm 2 of the pump lifting frame. The first core tube 200 near the second connecting rod 102 is fixedly connected to the second connecting rod 102, and the first core tube 200 near the fourth connecting rod 104 is fixedly connected to the fourth connecting rod 104. The length of the first connecting rod 101 can be flexibly adjusted to adapt to different well width requirements.

[0029] Preferably, the second connecting rod 102 includes a second sleeve 500, one end of which is connected to the first core tube 200, and the other end of which is inserted into a second core tube 600. The second sleeve 500 has multiple third screw holes 700, and the second core tube 600 has multiple fourth screw holes 800. The overlapping third screw holes 700 and fourth screw holes 800 are screwed together by bolts to fix the extension length of the second core tube 600. The end of the second core tube 600 away from the second sleeve 500 is fixedly connected to the third connecting rod 103, so that the length of the second connecting rod 102 can be flexibly adjusted to adapt to different well length requirements.

[0030] Similarly, the structural principles of the third link 103 and the fourth link 104 are the same as those of the second link 102, and will not be repeated here.

[0031] As a preferred option, such as Figure 1 As shown, a pulley 201 is installed on the upper arm 2 of the pump lifting frame to guide the wire rope of the winch 3. The pulley 201 optimizes the guiding path of the wire rope, reduces friction and wear of the wire rope, and improves the operating efficiency and service life of the device.

[0032] Preferably, the upper arm 2 of the pump lifting frame includes a vertical arm 204 and a horizontal arm 203. The vertical arm 204 is fixedly connected to the pump lifting frame base 1, and the horizontal arm 203 is fixedly connected to the vertical arm 204. A diagonal brace 202 is provided between the horizontal arm 203 and the vertical arm 204. The combination of the vertical arm 204 and the horizontal arm 203 allows the hook 6 to be located above the wellhead 4. At the same time, the diagonal brace 202 further improves the structural rigidity and anti-overturning ability.

[0033] Preferably, both the vertical arm 204 and the horizontal arm 203 are telescopic arms. The telescopic design of the vertical arm 204 can adjust the height of the upper arm 2 of the pump lifting frame according to different wellhead heights. The telescopic design of the horizontal arm 203 can guide the wire rope of the winch 3, so that the hook 6 is located directly above the wellhead 4. Optionally, the structural principle of the vertical arm 204 and the horizontal arm 203 is the same as that of the second connecting rod 102, which will not be described in detail here.

[0034] Preferably, a telescopic support rod 8 is provided on the horizontal arm 203. The end of the telescopic support rod 8 away from the horizontal arm 203 is in contact with the ground. The telescopic support rod 8 provides additional stability support to prevent the device from tipping over during operation. Optionally, the structural principle of the telescopic support rod 8 is the same as that of the second connecting rod 102, which will not be described in detail here.

[0035] Preferably, the first connecting rod 101 is provided with a fixed frame 7 for placing the winch 3. The fixed frame 7 is provided with a support rod 701. The end of the support rod 701 away from the fixed frame 7 is connected to the upper arm 2 of the pump lifting frame. The fixed frame 7 provides a stable installation position for the winch 3, avoiding displacement caused by vibration. At the same time, the support rod 701 further enhances the overall stability of the device.

[0036] This invention reduces reliance on manpower, enabling single-person operation. The wire rope guiding path is optimized through the cooperation of the winch 3 and pulley 201, improving operational efficiency. At the same time, the device can meet the needs of different well depths, terrains, and wellhead sizes by setting multiple telescopic structures. The telescopic structure design also makes the device more portable and suitable for field operations.

[0037] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
