Description

Technical Field

[0001] This utility model relates to the technical field of water discharge test devices, and more specifically, to a multi-hole pumping test instrument. Background Technology

[0002] In the field of underground exploration, multi-well pumping test instruments are used. Their main purpose is to conduct groundwater hydrogeological surveys. By pumping water from multiple clusters of wells and recording the pumping volume, water level difference, pressure, flow rate, and temperature changes, the flow characteristics, permeability, and groundwater reserves of groundwater can be observed, which helps to better manage groundwater resources.

[0003] The multi-hole pumping test instrument consists of pumping equipment, observation equipment, data acquisition equipment, and central control equipment. Among them, the pumping equipment is the most important, and the pumping pump is the main component. If the pumping pump is blocked or damaged, it can easily affect data such as water volume, leading to inaccurate data acquisition. Repeated operation is required to collect accurate data. Therefore, a filter screen is installed at the inlet of the pumping pump. However, the pumping pump generally runs 24 hours a day. During this period, the filter screen will filter out more impurities, which will affect the water output. However, the pumping pump cannot be stopped, which will result in inaccurate observation data.

[0004] Therefore, how to provide a multi-hole pumping test instrument is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] This invention provides a multi-hole pumping test instrument to solve the problem mentioned in the background art that existing pumps, when subjected to pumping tests, may have excessive impurities filtered through the filter screen, making it impossible to stop the pump for cleaning and thus affecting the water output and causing inaccurate observation data.

[0006] According to one aspect of the present invention, a multi-hole pumping test instrument is provided, including a test pumping pipe and a motor with a pump body installed. The test pumping pipe is connected to the water inlet pipe of the pump body through a filter box. A filter frame is installed inside the filter box. The filter frame includes a rotating shaft, a partition, and a filter plate. The partition is evenly arranged on the outer circular surface of the rotating shaft to form multiple isolation cavities. A filter plate is installed in each isolation cavity. A knob is installed outside the filter box. One end of the knob extends into the filter box and is connected to the rotating shaft.

[0007] Based on the above scheme, a preferred option is to fit a sealing side ring on the free end of the partition.

[0008] Based on the above scheme, a preferred embodiment is provided on the knob, wherein there are multiple grooves and the number of each groove corresponds to the number of the isolation cavity.

[0009] Based on the above scheme, a preferred embodiment is provided on the outer end face of the filter box, which is used to interact with the groove to fix the position of the knob.

[0010] Based on the above scheme, the limiting component includes a limiting cylinder, a spring installed in the limiting cylinder, and a positioning head. The limiting cylinder is installed on the filter box, one end of the spring abuts against the end face of the filter box, and the other end abuts against the positioning head. The end of the positioning head extends to the outside of the limiting cylinder and engages in the groove.

[0011] Based on the above scheme, the preferred option is that the center of the rotating shaft is provided with a groove, and the outer edge of the knob is provided with a protrusion that matches the groove.

[0012] This utility model discloses a multi-hole pumping test instrument. By setting a filter box in the test pumping pipe, the water can be filtered through the filter frame and filter plates installed on the filter frame. Furthermore, this utility model is equipped with a knob connected to a rotating shaft, which can control the rotation of the filter frame, thereby causing different filter plates on the filter frame to overlap with the test pumping pipe.

[0025] In the embodiments shown in the accompanying drawings, the directional indications (such as up, down, left, right, front, and back) used to explain the structure and movement of the various components of this invention are relative rather than absolute. These descriptions are appropriate when these components are in the positions shown in the drawings. If the descriptions of the positions of these components change, these directional indications also change accordingly.

[0026] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0027] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0028] Please see Figure 1 and combined Figure 2 and Figure 5 As shown, the present invention provides a multi-hole pumping test instrument, which includes a test pumping pipe and a motor 1 with a pump body 2 installed. Specifically, the pump body 2 is installed on the output shaft of the motor 1, and an inlet pipe 3 is provided on the pump body 2. The other end of the pump body 2 is connected to the test pumping pipe, and the free end of the test pumping pipe extends into the groundwater layer.

[0029] In addition, this utility model also provides a disc-shaped filter box 5 at the water inlet pipe 3 of the test water pump pipe and the pump body 2. The filter box 5 has a cavity inside, and a filter frame 4 is rotatably installed in the cavity.

[0030] The specific filter frame 4 includes a rotating shaft 7, a partition 8 and a filter plate 6. The partition 8 is evenly arranged on the outer circular surface of the rotating shaft 7 and the inner edge surface of the filter box 5 to form multiple isolation cavities. Each isolation cavity is equipped with a filter plate 6. A knob 15 is installed on the outside of the filter box 5. One end of the knob extends into the filter box 5 and is connected to the rotating shaft 7.

[0031] When the knob 15 is turned, the filter frame 4 rotates, which can drive the filter plates 6 in different isolation chambers to the cross section of the test water pumping pipe. Therefore, the filter plates 6 can filter impurities in the water. Moreover, since the filter box 5 is integrated with the test water pumping pipe or is sealed, when the filter plate 6 used accumulates a lot of impurities during use, the knob 15 can be used to drive the filter frame 4 to rotate, so that another filter plate 6 on the filter frame 4 can be rotated to the middle of the test water pumping pipe, so that the filter plate 6 can be replaced without stopping the pump body 2.

[0032] It is worth noting that the free end of the partition 8 of this utility model is fitted with a sealing side ring 9, and an inspection port 11 is provided on the filter box 5 to facilitate the replacement of the filter plate 6. The inspection port 11 is covered with a cover plate 13 by fixing bolts 14, and a sealing ring 12 is provided between the cover plate 13 and the filter box 5.

[0033] Furthermore, this utility model also provides a groove 16 on the knob 15. There are multiple grooves 16, and the number of each groove 16 corresponds to the isolation cavity. In use, when the rotating shaft 7 rotates, the different filter plates 6 corresponding to the isolation cavities separated by the partition plate 8 can be accurately rotated to the position of the water inlet pipe 3. The filter plates 6 are movably attached to one side of the inner wall of the filter box 5. Since the groove 16 corresponds to the isolation cavity, the position of the different filter plates 6 at the water inlet pipe 3 can be determined according to the rotation direction of the groove 16.

[0034] Please refer to the figure. A limiting component 17 is provided on the outer end face of the filter box 5 to interact with the groove 16 to fix the position of the knob 15.

[0035] Specifically, the limiting component 17 includes a limiting cylinder 18, a spring 20 installed in the limiting cylinder 18, and a positioning head 19. The limiting cylinder 18 is installed on the filter box 5. One end of the spring 20 presses against the end face of the filter box 5, and the other end abuts against the positioning head 19. One end of the positioning head 19 is provided with a stepped surface that engages with the end face of the limiting cylinder 18. The end of the positioning head 19 extends to the outside of the limiting cylinder 18 and engages in the groove 16.

[0036] Meanwhile, a slot 10 is provided at the center of the rotating shaft 7, and a protrusion is provided on the outer edge of the knob 15, which is adapted to the slot 10.

[0037] When the filter plate 6 corresponding to the water inlet pipe 3 is in a stable state, the spring 20 is in a telescopic state. At this time, the free end of the positioning head 19 is limited in the groove 16, so that the position between the knob 15 and the filter box 5 is relatively fixed to prevent the filter frame 4 from rotating.

[0038] When it is necessary to replace different filter plates 6 into the water inlet pipe 3, push the positioning head 19 downward to compress the spring 20, so that the positioning head 19 exits from the groove 16. At this time, since the positioning head 19 and the groove 16 are no longer limited, the interaction between the slot 10 on the rotating shaft 7 and the protrusion on the knob 15 can be used to rotate the knob 15 to drive the filter frame 4 to rotate, so that different filter plates 6 can be replaced into the water inlet pipe 3. It is convenient and quick to use.

[0039] During operation, the position of the filter plate 6 is observed by rotating the knob 15 and looking through the groove 16. After the filter plate 6 has been rotated, the spring 20 in the limiting assembly 17 applies elastic force to the positioning head 19. Then, the positioning head 19 extends out of the limiting cylinder 18 and enters the groove 16. The knob 15 is stabilized by engaging with the groove 16 to prevent the knob 15 from rotating. When the knob 15 is rotated, the positioning head 19 needs to be pressed down with a finger so that the chamfered position on the positioning head 19 is engaged with the edge of the groove 16. In this way, the positioning head 19 can be squeezed by the groove 16 and retracted into the limiting cylinder 18 when the knob 15 is rotated. The operation is very convenient.

[0040] This utility model discloses a multi-hole pumping test instrument. By setting a filter box 5 in the test pumping pipe, the water quality can be filtered through the filter frame 4 inside the filter box 5 and the filter plates 6 installed on the filter frame 4. Furthermore, this utility model is equipped with a knob 15, which is connected to a rotating shaft 7, to control the rotation of the filter frame 4. This causes the different filter plates 6 on the filter frame 4 to overlap with the test pumping pipe, thereby enabling the replacement of different filter plates 6 without stopping the pumping machine, thus ensuring the accuracy of the observation data.

[0041] This invention features a filter assembly with multiple filtration zones. Filtration occurs when one zone blocks the inlet pipe 3. When this zone becomes clogged with impurities, rotating the shaft 7 causes the filtration zones on the filter frame 4 to rotate, moving the impurity-laden zone away from the inlet pipe 3. This allows a fresh zone to enter the inlet pipe 3 for further filtration. This process effectively transfers impurities from the inlet pipe 3 during pumping, enabling the pump to operate continuously without interrupting the flow. This avoids affecting the water flow rate in the inlet pipe 3 and solves the problem in existing technologies where excessive impurities on the filter screen prevent pumping during pumping tests, leading to inaccurate data.

[0042] On the other hand, this utility model also provides an inspection port 11 on the filter box 5, which makes it convenient to open and clean the impurities inside the filter box 5 when the water pump is stopped, thus achieving the effect of effectively cleaning the impurities filtered in the filter assembly.

[0043] Meanwhile, this utility model sets a limiting component 17 to position the knob 15, so that the knob 15 drives the rotating shaft 7 to be stable. The stability of the rotating shaft 7 makes the filter plate 6 stable and not easy to rotate on its own, thus stabilizing the area of ​​the filter plate 6 located inside the water inlet pipe 3. Moreover, the position of the area divided between the partitions 8 can be accurately observed through the groove 16 on the knob 15.

[0044] Finally, the method described in this application is merely a preferred embodiment and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
