[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer to Figures 1-7 , the present utility model provides a pumping test device capable of measuring water flow, including an A extraction component 1, a B extraction component 2 is installed on the A extraction component 1, and a conveying component 3 and a filtering component 4 are installed in the A extraction component 1;

[0028] Among them, the A extraction component 1 includes an A housing 11, the A housing 11 is set to have a hollow internal structure, and two placement grooves are opened at the lower end of the A housing 11, and rotation grooves are opened in both of the two placement grooves;

[0029] The filtering component 4 includes a filter plate 41, a connecting block 42, A clamping teeth 43, a moving plate 44, B clamping teeth 45 and a B spring 46. The filter plate 41 is arranged in the A housing 11, the connecting block 42 is installed on the filter plate 41, a plurality of A clamping teeth 43 are provided, and a plurality of A clamping teeth 43 are all installed on the connecting block 42. The moving plate 44 is installed in the rotation groove, a plurality of B clamping teeth 45 are provided, and a plurality of B clamping teeth 45 are all installed on the moving plate 44. A plurality of B springs 46 are provided, and a plurality of B springs 46 are all installed in the rotation groove and connected to the moving plate 44, and the A clamping teeth 43 and the B clamping teeth 45 are clamped.

[0030] Specifically, during the pumping operation, the A extraction component 1 and the B extraction component 2 can be inserted into the pre-drilled holes. After inserting the A extraction component 1 and the B extraction component 2 into the holes, their heights can be adjusted so that they can reach the designated pumping position, and then the pumping operation can be carried out. During the pumping operation, the conveying component 3 can be connected to an external water pump, and then the pumping can be carried out through the conveying component 3. Moreover, during the pumping process, the water flow rate of the extracted water can be monitored through the conveying component 3. During the extraction process, in order to prevent a large amount of sediment from mixing into the water, a filtering component 4 can be arranged at the lower end of the A housing 11. Through the filtering component 4, the extracted water sample can be preliminarily filtered, so as to prevent a large amount of sediment from entering the interior of the A housing 11. Since the filtering component 4 is extremely likely to be blocked by sediment after long-term use, the filtering component 4 can be replaced after the pumping volume is significantly reduced, so as to efficiently complete the pumping operation.

[0031] Furthermore, when replacing the filtering component 4, the moving plate 44 can be pressed upward. Since a plurality of B engaging teeth 45 are arranged on the moving plate 44, and a plurality of B springs 46 are arranged between the moving plate 44 and the rotating groove, when the moving plate 44 is pressed, the B springs 46 will be compressed at this time. And since a connecting block 42 is installed on the filter plate 41, and a plurality of A engaging teeth 43 are installed on the connecting block 42, during use, the A engaging teeth 43 and the B engaging teeth 45 are engaged with each other to limit the filter plate 41 and prevent the filter plate 41 from deflecting in the reverse direction, thereby causing the filter plate 41 to fall off. When removing the filter plate 41, by pressing the moving plate 44 at this time, the engagement between the A engaging teeth 43 and the B engaging teeth 45 is released, and the filter plate 41 can be rotated in the reverse direction to take it out. When installing the filter plate 41, the connecting block 42 can be first slidably arranged in the placing groove, and then the filter plate 41 and the connecting block 42 are rotated. During the rotation, the A engaging teeth 43 will continuously press the B engaging teeth 45, thereby pushing the moving plate 44 to move up and down. After the connecting block 42 is completely rotated to the end of the rotating groove, the A engaging teeth 43 and the B engaging teeth 45 will be engaged with each other, thereby preventing the filter plate 41 and the connecting block 42 from rotating in the reverse direction.

[0032] In this embodiment, both the connecting block 42 and the plurality of A engaging teeth 43 are provided in two groups, and the two connecting blocks 42 are both installed on the filter plate 41.

[0033] Specifically, in order to stably set the filter plate 41, two connecting blocks 42 can be provided on the surface of the filter plate 41, and a plurality of A engaging teeth 43 are provided on each connecting block 42. During use, since there are two rotating grooves, a moving plate 44 and a plurality of B springs 46 can be provided in each rotating groove, and a plurality of B engaging teeth 45 are provided on each moving plate 44. Through the cooperation and engagement of the two groups of moving plates 44 and B engaging teeth 45 with the two groups of connecting blocks 42 and A engaging teeth 43, the filter plate 41 can be stably set.

[0034] In this embodiment, the A extraction assembly 1 further includes a connecting pipe 12, an A engaging rack 13 and an A spring 14. A sliding groove is provided on the connecting pipe 12, the A engaging rack 13 is arranged in the sliding groove, a plurality of A springs 14 are provided, and the plurality of A springs 14 are all installed in the sliding groove and connected to the A engaging rack 13; the B extraction assembly 2 includes a B housing 21 and a sleeve 22, the sleeve 22 is installed at the lower end of the B housing 21, and the sizes and shapes of the B housing 21 and the A housing 11 are the same; the B extraction assembly 2 further includes a B engaging rack 23, the B engaging rack 23 is installed in the sleeve 22, and the B engaging rack 23 is engaged with the A engaging rack 13.

[0035] Specifically, during specific use, in order to connect the A housing 11 and the B housing 21, a connecting pipe 12 can be provided on the A housing 11, a plurality of A springs 14 can be provided on the connecting pipe 12, and the A engaging rack 13 is connected to the A springs 14. Then, a sleeve 22 can be provided on the B housing 21, and a B engaging rack 23 is provided in the sleeve 22. When connecting the A housing 11 and the B housing 21, the sleeve 22 can be sleeved on the connecting pipe 12 first, and then the B housing 21 and the sleeve 22 can be moved downward. At this time, the B engaging rack 23 will inwardly squeeze the A engaging rack 13. After the sleeve 22 moves to the end, the B engaging rack 23 and the A engaging rack 13 are engaged and cannot move upward, so that the A housing 11 and the connecting pipe 12 can be stably connected.

[0036] In this embodiment, the conveying assembly 3 includes a flowmeter 31, a conveying pipe 32 and a filter head 33. The filter head 33 is arranged inside the A housing 11, the conveying pipe 32 is installed on the filter head 33 and communicates with the filter head 33, and the flowmeter 31 is installed at the end of the conveying pipe 32.

[0037] Specifically, during the pumping operation, in order to further filter the extracted water sample, a filter head 33 can be arranged inside the A housing 11, and a delivery pipe 32 can be arranged on the filter head 33, so that the extracted water sample can be transported outside the device. A flowmeter 31 can be arranged on the delivery pipe 32 to monitor the water flow rate of the extracted water sample. Connecting the delivery pipe 32 to an external water pump can transport the water sample to the outside world.

[0038] Furthermore, since there may be differences in water samples at different heights inside the hole, generally during the extraction operation, it is necessary to extract water samples at different heights. In order to be able to extract water samples at different heights simultaneously, in actual use, the structure on the B housing 21 can be set the same as that of the A housing 11, and a delivery component 3 and a filtering component 4 can also be arranged on the B housing 21. At this time, the water samples at different heights can be extracted simultaneously through the A housing 11 and the connecting pipe 12.

[0039] In this embodiment, both the connecting pipe 12 and the sleeve 22 are set to have a hollow internal structure, and the delivery pipe 32 is arranged inside the connecting pipe 12 and the sleeve 22.

[0040] Specifically, in actual use, in order to prevent the surface of the delivery pipe 32 from being damaged, the delivery pipe 32 can be arranged inside the connecting pipe 12 and the sleeve 22.

[0041] The working principle and usage process of this utility model: When extracting the water sample inside the drilled hole, the A extraction component 1 and the B extraction component 2 can be connected first. According to the test requirements, multiple groups of A extraction components 1 and B extraction components 2 can be connected to meet the extraction of water samples at different heights. When extracting the water sample, an external water pump can be connected to the delivery component 3, and then the water sample inside the hole can be extracted and measured. In order to prevent a large amount of sediment from being contained in the extracted water sample, a filtering component 4 can be arranged on the A extraction component 1 and the B extraction component 2. The water sample can be filtered through the filtering component 4. If the filter plate 41 becomes blocked after long-term use, at this time, the filter plate 41 and the connecting block 42 can be quickly removed to replace the filter plate 41.

[0042] The electronic components and modules used in the content of this utility model can all be commonly used on the current market and can realize the specific functions in this case. The specific models and sizes can be selected and adjusted according to actual needs.
