Description

Technical Field

[0001] This application relates to the technical field of hydrogeological exploration tests, and in particular to a simple pumping test device using the bucket-lifting method. Background Technique

[0002] In hydrogeological exploration, the pumping test is a common hydrogeological test method. The pumping test is based on the groundwater well flow theory. Through pumping and observation in the well hole, it studies the relationship between the well discharge and the drawdown, the relationship between the pumping duration, the hydraulic connection between aquifers and between the aquifer and the surface water body, obtains the hydrogeological parameters of the aquifer, and evaluates the water-richness of the aquifer. It is a field hydrogeological test.

[0003] In actual hydrogeological exploration work, due to the large difference in water-richness in the mining area, there may be situations where the water volume in the exploration hole is very small or there is too much sediment and it cannot be washed clean during the pumping test. Traditional submersible pumps cannot meet the requirements of the pumping test.

[0004] For the conventional bucket-lifting method device, during operation, the test personnel need to manually lift water for a long time and measure and record the water level. This traditional method is cumbersome to operate, has a large working intensity, usually requires multiple people to cooperate to complete the recording, and there is a large error in the time of manual water lifting, which is not convenient to use. Content of the Utility Model

[0005] In order to solve the problem that the pumping test cannot be carried out when the water volume in the small-diameter exploration hole is small or the sediment content is high, and at the same time effectively solve the technical problems of the large working intensity of the test personnel's manual lifting and the large error in the time of manual water lifting, this application provides a simple pumping test device using the bucket-lifting method.

[0006] The simple pumping test device using the bucket-lifting method provided by this application adopts the following technical solutions:

[0007] A simple pumping test device using the bucket-lifting method includes a bracket, a pumping mechanism, and a water level measurement and recording mechanism;

[0008] The bracket is located directly above the opening of the exploration hole and is fixed to the ground around the exploration hole. The pumping mechanism includes a bucket, a first lifting assembly, and a water guide trough pipe. The bucket is located in the exploration hole. The first lifting assembly is installed on the bracket. The first lifting assembly is used to drive the bucket to move vertically up and down. The water guide trough pipe is installed on one side of the lifting assembly and one end corresponds to the opening of the exploration hole;

[0009] The water level measurement and recording mechanism includes a water level measurement probe, a second lifting assembly, and a water level display. The water level measurement probe is located in the exploration hole. The second lifting assembly is installed on the bracket. The second lifting assembly is used to drive the water level measurement probe to move vertically up and down. The water level display is electrically connected to the second lifting assembly and is used to reflect the groundwater level in the exploration hole.

[0010] By adopting the above technical solution, the first lifting component can drive the water bucket into the exploration hole to pump water from the exploration hole, and drive the water bucket to quickly move upward out of the exploration hole to ensure the test accuracy. After that, the pumped water can be poured into the water guide trough pipe and drained away. The second lifting component can also quickly lift and lower the water level measuring probe, and the water level display can timely display the water level, so as to reduce the test error, and at the same time, multiple staff members do not need to work simultaneously. Thus, on the premise of solving the problem that pumping tests cannot be carried out in small-diameter exploration holes with small water volume or high sediment content, the work intensity of the staff is reduced and the test accuracy is improved.

[0011] Optionally, the first lifting component includes a steel wire rope and an electric hoist. One end of the steel wire rope is wound around the drum of the electric hoist, and the other end of the steel wire rope enters the exploration hole and is connected to the water bucket.

[0012] By adopting the above technical solution, the rotation of the electric hoist is used to control the length of the steel wire rope in the exploration hole, so as to control the lifting and lowering of the water bucket, saving manpower while increasing the lifting and lowering speed of the water bucket, ensuring the test accuracy and reducing errors.

[0013] Optionally, the second lifting component includes a roller, a rotating frame, a motor and a cable. The roller is horizontally arranged and rotatably installed around its own axis on the rotating frame. The motor is installed on the rotating frame and is coaxially and fixedly connected to the roller. The rotating frame is installed on the bracket. One end of the cable is wound around the roller and is electrically connected to the water level display, and the other end of the cable is electrically connected to the water level measuring probe.

[0014] By adopting the above technical solution, the information of the water level measuring probe can be transmitted to the water level display through the cable. The combination of the water level measuring probe, the cable and the digital display screen can measure the water level, and the water level is converted according to water pressure, the specific gravity of water and atmospheric pressure. The recording personnel can timely read the hydrographic parameters in the pumping test according to the digital display screen, saving manpower while ensuring the test accuracy and reducing errors.

[0015] Optionally, the water bucket is made of a transparent material, and a scale for displaying the water level of the water bucket is provided on the peripheral wall of the water bucket, and the scale is arranged along the axial direction of the water bucket.

[0016] By adopting the above technical solution, the transparent material can more accurately calculate and control the water output to ensure the test accuracy.

[0017] Optionally, a handle is installed at the opening of the water bucket. The two ends of the handle are arranged oppositely and are respectively hinged to the peripheral wall of the water bucket. The handle is an upwardly convex arch, and the highest point of the handle is located on the axis of the water bucket. The steel wire rope is connected to the handle.

[0018] By adopting the above technical solution, through the shape of the handle, the stability of the bucket can be improved when connecting the steel wire rope, and the probability of the bucket deflecting in the exploration hole and affecting the test accuracy can be reduced.

[0019] Optionally, a lifting ring is fixedly connected to the highest point of the handle, a connecting ring is fixed on the steel wire rope, the connecting ring and the lifting ring are buckled, and the connecting ring is rotatably connected to the lifting ring around the axis of the lifting ring.

[0020] By adopting the above technical solution, through the lifting ring and the connecting ring, the stability at the bucket can be further improved, the connection difficulty between the steel wire rope and the bucket can be reduced, and the bucket can be kept in a vertically arranged state without external force.

[0021] Optionally, a hemispherical balance block is arranged at the bottom of the bucket, the balance block is coaxially connected with the bucket, and the convex surface of the balance block is arranged downward.

[0022] By adopting the above technical solution, through the balance block, the center of gravity of the bucket can be lowered, the bucket is not easily deflected, and at the same time, the speed of the bucket returning to the vertical state when deflected is accelerated.

[0023] Optionally, the diameter of the balance block is larger than the diameter of the bucket, a water diversion pipe inclined upward in the axial direction of the exploration hole is communicated with one end of the water diversion trough pipe facing the exploration hole, and a limiting plate is arranged on the side wall of the port of the water diversion pipe facing the exploration hole, and the limiting plate is used for clamping with the balance block.

[0024] By adopting the above technical solution, after the bucket moves above the exploration hole, after the staff reads the data, the water pumped in the bucket is poured into the water diversion trough pipe. By placing the balance block above the limiting plate, as the bucket continues to rise, the balance block abuts against the limiting plate and guides the bucket to tilt towards the water diversion pipe, so as to facilitate the staff to control the bucket to pour water into the water diversion pipe and reduce the difficulty of the staff pouring water.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. The first lifting component can drive the bucket to quickly lift and lower into the exploration hole, and the second lifting component can also make the water level measurement probe quickly lift and lower. The water level display can display the water level in time, so as to ensure the test accuracy, and at the same time, multiple staff do not need to work simultaneously. Therefore, on the premise of solving the problem that pumping tests cannot be carried out in small-diameter exploration holes with small water volume or high sediment content, the work intensity of the staff is reduced and the test accuracy is improved;

[0027] 2. Through the transparent material, the water output can be calculated and controlled more accurately, ensuring the test accuracy;

[0033] The following further describes the present application in detail Figure 1-2 in conjunction with the drawings.

[0034] It should be noted that in the description of the present invention, it should be understood that the terms "center", "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0035] The embodiment of the present application discloses a simple pumping test device using the bucket method.

[0036] Referring to Figure 1 and Figure 2 , the device includes a bracket 1, a pumping mechanism and a water level measurement and recording mechanism. The bracket 1 is located directly above the opening of the exploration hole and is fixed to the ground around the exploration hole.

[0037] Among them, the pumping mechanism includes a bucket 2, a first lifting assembly 3 and a water guide trough pipe 4. The bucket 2 is located in the exploration hole, the first lifting assembly 3 is installed on the bracket 1, the first lifting assembly 3 is used to drive the bucket 2 to move vertically up and down, and the water guide trough pipe 4 is installed on one side of the lifting assembly and one end corresponds to the opening of the exploration hole.

[0038] The bucket 2 is located in the exploration hole for easy pumping. Through the first lifting assembly 3, the bucket 2 can be quickly lifted above the exploration hole for staff to observe after pumping, which not only saves manpower but also avoids the occurrence of test errors caused by excessive manual pulling of the bucket 2 for a long time.

[0039] In order to observe the water volume in the bucket 2 faster and more accurately, the bucket 2 is made of transparent material. A scale for displaying the water level of the bucket 2 is provided on the peripheral wall of the bucket 2, and the scale is arranged along the axial direction of the bucket 2. This is convenient for more accurately calculating and controlling the water output to ensure the test accuracy.

[0040] The water stored in the bucket 2 can be directly poured into the water guide trough pipe 4 after the data is recorded, which saves time and effort and enables the bucket 2 to quickly enter the exploration hole again.

[0041] In addition, the water level measurement and recording mechanism includes a water level measurement probe 5, a second lifting assembly 6, and a water level display 7. For the water level measurement probe 5, the bucket 2 is located in the exploration hole. The second lifting assembly 6 is installed on the bracket 1. The second lifting assembly 6 is used to drive the water level measurement probe 5 to lift vertically. The water level display 7 is electrically connected to the second lifting assembly 6 and is used to display the depth of the water level measurement probe 5.

[0042] Through the second lifting assembly 6, the water level measurement probe 5 can also be quickly lifted and lowered, and the water level display 7 can display the water level in a timely manner to reduce test errors. This enables the entire experiment to be carried out without multiple staff working simultaneously. Thus, on the premise of solving the problem that pumping tests cannot be carried out in small-diameter exploration holes with small water volume or high sediment content, the work intensity of the staff is reduced and the test accuracy is improved.

[0043] Refer to Figure 1 and Figure 2 , the first lifting assembly 3 includes a steel wire rope 31 and an electric winch 32. One end of the steel wire rope 31 is wound around the drum of the electric winch 32, and the other end of the steel wire rope 31 enters the exploration hole and is connected to the bucket 2.

[0044] The rotation of the electric winch controls the length of the steel wire rope 31 in the exploration hole, thereby controlling the lifting and lowering of the bucket 2, saving manpower while increasing the lifting and lowering speed of the bucket 2, ensuring the test accuracy, and reducing errors.

[0045] To avoid the situation that the skewed connection position between the steel wire rope 31 and the bucket 2 causes the bucket 2 to tilt and affect the measurement accuracy, refer to Figure 1 and Figure 2, a handle 33 is installed at the opening of the bucket 2. The two ends of the handle 33 are arranged oppositely and are respectively hinged to the peripheral wall of the bucket 2. The handle 33 is an upwardly convex arch shape and the highest point of the handle 33 is located on the axis of the bucket 2. A hanging ring 34 is fixedly connected to the highest point of the handle 33. A connecting ring 35 is fixed on the steel wire rope 31. The connecting ring 35 and the hanging ring 34 are buckled, and the connecting ring 35 is rotationally connected to the hanging ring 34 around the axis of the hanging ring 34.

[0046] The shape of the handle 33 and the hanging ring 34 can reduce the difficulty of finding the axis of the bucket 2. The connecting ring 35 and the hanging ring 34 can reduce the connection difficulty between the steel wire rope 31 and the bucket 2. When the connecting ring 35 is at the uppermost position of the hanging ring 34, the axis of the bucket 2 is directly opposite to the steel wire rope 31, and the bucket 2 is in a vertically arranged state.

[0047] In order to reduce the probability that the bucket 2 cannot be corrected due to external force skew and improve the stability of the bucket 2, referring to Figure 1 and Figure 2 , a hemispherical balance weight 8 is arranged at the bottom of the bucket 2. The balance weight 8 is coaxially connected to the bucket 2, and the convex surface of the balance weight 8 is arranged downward. The balance weight 8 can reduce the center of gravity of the bucket 2 and make the bucket 2 not easy to skew.

[0048] When the pumped water in the bucket 2 needs to be poured out, referring to Figure 2 , the diameter of the balance weight 8 is larger than the diameter of the bucket 2. One end of the water guide trough pipe facing the exploration hole is a water inlet pipe section 41 that is inclined upward in the direction of the axis of the exploration hole. A limiting plate 9 is arranged on the side wall of the port of the water inlet pipe facing the exploration hole. As the bucket 2 rises, the limiting plate 9 abuts against the balance weight 8. As the bucket 2 continues to rise, it can guide the bucket 2 to tilt in the direction close to the water inlet pipe, so as to reduce the difficulty for the staff to control the bucket 2 to pour water into the water guide trough pipe 4.

[0049] Referring to Figure 1 , the second lifting assembly 6 includes a roller 61, a rotating frame 62, a motor 63 and a cable 64. The roller 61 is horizontally arranged and is rotationally installed on the rotating frame 62 around its own axis. The motor 63 is installed on the rotating frame 62 and is coaxially and fixedly connected to the roller 61. The rotating frame 62 is installed on the bracket 1. One end of the cable 64 is wound around the roller 61 and is electrically connected to the water level display 7, and the other end of the cable 64 is electrically connected to the water level measuring probe 5.

[0050] The water level display 7 can be a digital display screen. The digital display screen can record the water level data in real time. The test personnel can read the water level data later, which can avoid the tediousness of multiple-person operation.

[0051] Through the roller 61 to facilitate the winding of the cable 64, so that the cable 64 drives the water level measurement probe 5 to move longitudinally, and the depth of the water level detection probe's descent can be recorded in real time. The water level can be measured by combining the water level measurement probe 5, the cable 64, and the digital display screen. The water level is converted from water pressure, the specific gravity of water, and atmospheric pressure. The recording personnel can read the hydrogeological parameters in the pumping test in a timely manner according to the digital display screen, saving manpower while ensuring the test accuracy and reducing errors.

[0052] The device of the present application can be used in boreholes and shallow wells in the weakly water-rich distribution area of loose rock pore water, and can also be used in bare hole exploration holes with small water volume or high sediment content in hydrogeological surveys such as coal mines, salt lakes, and metal mines to solve the problem that traditional submersible pumps cannot meet the requirements of pumping tests.

[0053] The implementation principle of a simple pumping test device using the bucket-lifting method in an embodiment of the present application is as follows: The implementation steps at the start of the test are as shown below:

[0054] 1. Install the device on the exploration hole after drilling and well flushing.

[0055] 2. Determine the diameter of the bucket 2 according to the inner diameter of the exploration hole, estimate the water inflow according to the type of exploration hole, set the length of the bucket 2, and then calculate the volume of the bucket 2 to customize the bucket 2.

[0056] 3. Drive the roller 61 to rotate by clicking, so that the water level measurement probe 5 descends into the exploration hole to a certain depth. The digital display screen shows the depth of the water level measurement probe 5. The staff measures the atmospheric pressure and the density of groundwater in a timely manner and converts the actual water level.

[0057] 4. Start the simple pumping test. Drive the bucket 2 to pump out the groundwater through the first lifting component 3 and pour the extracted groundwater into the diversion trough to drain it away. Record the water volume in the bucket 2 and convert it into the water inflow according to the water volume of the extracted groundwater.

[0058] 5. Calculate the hydrogeological parameters according to the recorded water level drawdown and water inflow.

[0059] The entire experiment of the present application does not require multiple staff to work simultaneously. Thus, on the premise of solving the problem that pumping tests cannot be carried out in small-diameter exploration holes with small water volume or high sediment content, the work intensity of the staff is reduced and the test accuracy is improved.

[0060] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
