Description

Technical Field

[0001] This utility model relates to the field of groundwater sampling technology, and in particular to a groundwater sampling device capable of storing multiple samples. Background Technology

[0002] Groundwater sampling refers to the process of sampling water that exists in the pores of rocks below the ground surface. Due to current environmental pollution and damage, groundwater sampling and testing are necessary to ensure the effective use of water resources and to ensure the normal use of groundwater. In order to conduct multi-layer testing of groundwater, groundwater sampling devices that can store multiple samples are required.

[0003] The applicant discovered through a search that a Chinese patent discloses "A Groundwater Sampling Device Capable of Preserving Multiple Samples," with publication (announcement) number "CN219714887U." This patent mainly uses sampling pipes to pump groundwater into corresponding pumping pipes for groundwater sampling. Multiple pumping pipes are set up to extract and preserve multiple groundwater samples, thus achieving the effect of preserving multiple samples. The multiple pumping pipes have different lengths, which can sample groundwater at different depths, increasing the functionality of the sampling. However, the above structure uses multiple pumping pipes to sample at different water levels. By setting up multiple pipe structures for sampling, not only is the overall sampling device large in size, but it may also collide with the inner wall of the sampling well during sampling, or even get stuck in the sampling well, affecting the normal use of the sampling device. Furthermore, due to the limitation of the pipe length itself, it is impossible to sample deeper locations during the sampling process, which will affect the performance of the sampling device. Utility Model Content

[0004] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0005] A groundwater sampling device capable of storing multiple samples includes a sampling shell, a pull rope fixedly connected to the center of the top surface of the sampling shell, a connecting plate rotatably connected to the upper side of the inner wall of the sampling shell, and storage cylinders fixedly connected to the four sides of the bottom surface of the connecting plate.

[0006] The bottom surfaces of all four storage cylinders are in contact with the lower side of the inner wall of the sampling shell. A water inlet is provided on the lower side of the inner wall of the sampling shell, located on the lower side of one of the storage cylinders. Water outlets are provided on the upper side of the inner wall of the sampling shell and the top surface of the connecting plate, located on the upper side of all four storage cylinders. A water solenoid valve is fixedly connected to the inner wall of the water inlet. A transmission mechanism is provided inside the sampling shell on one side of the connecting plate.

[0007] Furthermore, the transmission mechanism includes a power chamber located inside one side of the sampling shell. A waterproof motor is fixedly connected to the lower side of the inner wall of the power chamber. The output end of the waterproof motor is rotatably connected to one side of the inner wall of the power chamber. A power gear is fixedly connected to the output shaft of the waterproof motor. A transmission port is provided on the side of the inner wall of the power chamber near the connecting plate. A connecting mechanism is provided on the surface of the connecting plate.

[0008] Furthermore, the connecting mechanism includes a connecting ring groove formed on the surface of the connecting disc, and an external gear ring is fixedly connected to the inner wall of the connecting ring groove. The surface of the external gear ring meshes with the surface of the power gear.

[0009] Furthermore, guide pipes are fixedly connected to the upper side of the inner wall of each of the four water outlets, and valve bodies are provided on the surface of each of the four guide pipes.

[0010] Furthermore, a waterproof wire is fixedly connected to the top surface of the sampling shell on one side of the pull rope.

[0011] Furthermore, the sampling shell is made of stainless steel.

[0012] Furthermore, a plurality of support blocks are fixedly connected to the bottom surface of the sampling shell, and the plurality of support blocks are arranged in a circular array around the center of the bottom surface of the sampling shell.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. This utility model device utilizes a waterproof motor to drive a power gear to rotate. The power gear, through the connection effect of the external gear ring, enables the connecting disc to rotate. This rotation of the connecting disc moves different storage cylinders to the water inlet position. After the solenoid valve is opened, water can enter the storage cylinders. The rotation of the connecting disc ensures the annular rotation and collection effect of different storage cylinders, thereby ensuring the stratified sampling of the device. Through the above structure, this device adopts a sampling structure with an internal annular pipe, which not only greatly reduces the overall size of the device and avoids the problem of getting stuck in the sampling well, ensuring the normal use function of the device, but also enables the device to sample groundwater at different depths, even deeper ones, increasing the performance of the device.

[0020] 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.

[0021] like Figure 1-4 As shown, a groundwater sampling device capable of storing multiple samples includes a sampling shell 1, a pull rope 2 fixedly connected to the center of the top surface of the sampling shell 1, a connecting plate 3 rotatably connected to the upper side of the inner wall of the sampling shell 1, and storage cylinders 4 fixedly connected to the four sides of the bottom surface of the connecting plate 3.

[0022] The bottom surfaces of all four storage cylinders 4 are in contact with the lower side of the inner wall of the sampling shell 1. A water inlet 5 is located on the lower side of the inner wall of one of the storage cylinders 4. Water outlets 6 are located on the upper side of the inner wall of the sampling shell 1 and the top surface of the connecting plate 3 on the upper side of all four storage cylinders 4. When it is necessary to remove the sample from the storage cylinder 4, after lifting the sampling shell 1, with the guide tube 14 positioned at the bottom, the water solenoid valve 7 is opened, and the waterproof motor 9 is started to rotate. The storage cylinder 4 is then rotated to the bottom of the water solenoid valve 7 to remove it. The sample inside the inlet 5 is fixedly connected to a water solenoid valve 7. A transmission mechanism is located inside the sampling shell 1 on one side of the connecting plate 3. The transmission mechanism includes a power chamber 8 located inside the sampling shell 1. A waterproof motor 9 is fixedly connected to the lower side of the inner wall of the power chamber 8. The number of rotations of the waterproof motor 9 is fixed to ensure that the storage cylinder 4 rotates to the corresponding outlet 6. The output end of the waterproof motor 9 is rotatably connected to one side of the inner wall of the power chamber 8. A power gear 1 is fixedly connected to the output shaft of the waterproof motor 9. 0. A transmission port 11 is provided on the inner wall of the power chamber 8 near the connecting plate 3. The waterproof motor 9 drives the power gear 10 to rotate. The power gear 10, through the connection effect of the external gear ring 13, enables the connecting plate 3 to rotate. This rotation of the connecting plate 3 moves different storage cylinders 4 to the position of the water inlet 5. After the solenoid valve 7 is opened, water can enter into the storage cylinder 4. Through the rotation of the connecting plate 3, the annular rotation collection effect of different storage cylinders 4 can be ensured, thereby ensuring the stratified sampling of the device. Through the above structure, the device adopts a sampling structure with an internal annular pipe, which not only greatly reduces the overall size of the device and avoids the problem of getting stuck in the sampling well, but also ensures the normal use function of the device. The device can also sample groundwater at different depths, even deeper ones, increasing the performance of the device. The surface of the connecting plate 3 is provided with a connecting mechanism, which includes a connecting ring groove 12 on the surface of the connecting plate 3. An external gear ring 13 is fixedly connected to the inner wall of the connecting ring groove 12. The surface of the external gear ring 13 meshes with the surface of the power gear 10.

[0023] like Figure 1-3 As shown, in some embodiments, guide pipes 14 are fixedly connected to the upper side of the inner wall of each of the four outlets 6. Each of the four guide pipes 14 is provided with a valve body 15. The valve body 15 and the guide pipes 14 facilitate the connection of pipes for pumping water through the ground structure. A waterproof wire 16 is fixedly connected to the top surface of the sampling shell 1 on one side of the pull rope 2. The sampling shell 1 is made of stainless steel. Multiple support blocks 17 are fixedly connected to the bottom surface of the sampling shell 1. The support blocks 17 ensure the stability of the sampling shell 1 during placement and prevent the mud from clogging the inlet 5. The multiple support blocks 17 are arranged in a circular array around the center of the bottom surface of the sampling shell 1.

[0024] The working principle of this utility model is as follows: When the device is in use, the waterproof motor 9 drives the power gear 10 to rotate. The power gear 10, through its connection with the external gear ring 13, ensures the rotation of the connecting plate 3. This rotation of the connecting plate 3 ensures that the different storage cylinders 4 move to the position of the water inlet 5. When the different storage cylinders 4 move to the position of the water inlet 5, the water solenoid valve 7 opens, ensuring that water enters into the storage cylinder 4. Because the valve body 15 is in the open state during sampling, the water solenoid valve 7 opens, ensuring that water flows in through the water inlet 5 and flows to the position of the water outlet 6. When the water solenoid valve 7 closes, there will be gas or previously stored water in the storage cylinder 4, and no liquid flow will occur in the storage cylinder 4. The internal pressure is a fixed value, and water at this depth will not flow into the storage cylinder 4, thus ensuring the stratified sampling effect of the device.

[0025] The device ensures overall energy use through the waterproof cable 16, and the extension and retraction of the pull rope 2 can better ensure the sampling effect of groundwater at different depths, thus ensuring the adaptability of the device.

[0026] This utility model emphasizes innovative structure and does not elaborate on existing mature technologies and structures.

[0027] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
