Its core content covers multiple aspects such as survey objectives, tasks, methods and procedures. Hydrogeological engineering survey sampling is an important step in obtaining water samples to analyze their physical and chemical properties.

[0003] A search revealed a utility model patent with publication number CN222212347U, which discloses a sampling device for engineering hydrogeological exploration, belonging to the field of geological exploration technology. The device includes a base plate, a frame fixed to the top of the base plate, a scale fixed to the top of the base plate, and an adjustment component for adjusting the height of the sampling device installed inside the frame. A sampling component for sampling the target water source is installed at the bottom of the adjustment component. The sampling component includes an adjustment cylinder slidably connected to the rear side wall of the frame, a sampling cup slidably connected inside the adjustment cylinder, and a conical head threaded to the bottom of the adjustment cylinder. This sampling device for engineering hydrogeological exploration can effectively and accurately sample water sources at the target depth, effectively avoiding the possibility of water samples containing water from other depths, thus ensuring the accuracy of water source detection at the target depth and achieving the expected results, thereby improving the practicality of the sampling device for engineering hydrogeological exploration.

[0004] Existing hydrological sampling devices collect water samples by inserting the sampling equipment into the target water area. However, this sampling method is prone to causing large impurities from the water source, such as aquatic plants or garbage, to enter the equipment, which can easily lead to blockages and affect the normal sampling operation.

[0005] Therefore, it is necessary to invent a sampling device for engineering hydrogeological exploration to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a sampling device for engineering hydrogeological exploration. By using the short-distance reciprocating motion of the cleaning cylinder, the cleaning rod can clean the filter tank. Furthermore, the continuous movement of the cleaning cylinder can adjust the sampling length, thereby solving the problem of clogging that easily occurs during sampling in existing technologies.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a sampling device for engineering hydrogeological exploration, including a sampling cylinder, a small water pump installed above the sampling cylinder, and the input end of the small water pump being connected through the inside of the sampling cylinder. The drive assembly located on the outside of the sampling cylinder includes a thread, the thread being formed on the outer surface of the sampling cylinder, and an internally threaded cylinder is sleeved on the sampling cylinder, and the internally threaded cylinder is screwed to the thread. The cleaning assembly installed inside the sampling tube includes a water suction pipe that runs through the sampling tube. A sealing ring is fitted and fixed to the water suction pipe and fits against the inner wall of the sampling tube.

[0008] Preferably, the drive assembly further includes a toothed ring, which is sleeved and fixed on an internally threaded cylinder. A positioning ring is installed on the inner wall of the internally threaded cylinder. A fixed cylinder is sleeved on the sampling cylinder. An annular groove is formed on the surface of the fixed cylinder, and the annular groove is slidably connected to the positioning ring.

[0009] Preferably, a servo motor is installed on one side of the fixed cylinder, and a gear is installed at the output end of the servo motor, and the gear meshes with a gear ring.

[0010] Preferably, the cleaning component further includes a water intake cylinder, which is connected through to the bottom of the water pumping pipe, and multiple sets of filter grooves are arranged in a ring on the inner wall of the water intake cylinder.

[0011] Preferably, a cleaning cylinder is fitted onto the water intake cylinder, and multiple sets of cleaning rods are installed in a ring on the inner wall of the cleaning cylinder, with the cleaning rods being slidably connected to the corresponding filter tanks.

[0012] Preferably, push rods are symmetrically installed on one side of the cleaning cylinder, a limit ring is fixedly fitted on the sampling cylinder, the limit ring is connected through the push rod, and the push rod is fixedly connected to one side of the fixed cylinder.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows: The water drawn in can be filtered through the filter tank, while the short-distance reciprocating motion of the cleaning cylinder drives the cleaning rod to clean the filter tank. The continuous movement of the cleaning cylinder also moves the pumping pipe within the sampling cylinder, allowing for adjustment of the sampling length. This structure enables the sampling device to filter water and clean the filtered area simultaneously, effectively preventing impurities from entering the device. Furthermore, this structure allows for effective adjustment of the sampling distance, significantly improving the practicality of the sampling device. Attached Figure Description

[0017] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0018] This utility model provides, for example Figure 1-5 The sampling device shown includes a sampling cylinder 001, a small water pump 101 installed above the sampling cylinder 001, and the input end of the small water pump 101 is connected to the inside of the sampling cylinder 001. The sampling tube 001 allows the small water pump 101 to draw water into it for sampling.

[0019] The drive assembly 002 located on the outside of the sampling cylinder 001 includes a thread 201, which is formed on the outer surface of the sampling cylinder 001. An internally threaded cylinder 202 is sleeved on the sampling cylinder 001 and is screwed to the thread 201. The internal threaded cylinder 202 moves up and down during rotation via the thread 201.

[0020] The cleaning component 003 installed inside the sampling cylinder 001 includes a water suction pipe 301, which is connected through the sampling cylinder 001. A sealing ring 302 is fitted and fixed on the water suction pipe 301, and the sealing ring 302 is in contact with the inner wall of the sampling cylinder 001.

[0021] By moving the water pump 301 within the sampling cylinder 001, the water sampling length of the small water pump 101 can be extended, and the sealing ring 302 can ensure the sealing of the inside of the sampling cylinder 001.

[0022] Furthermore, in the above structure, the drive assembly 002 also includes a toothed ring 203, which is sleeved and fixed on the internal threaded cylinder 202. A positioning ring 208 is installed on the inner wall of the internal threaded cylinder 202. A fixed cylinder 204 is sleeved on the sampling cylinder 001. An annular groove 205 is opened on the surface of the fixed cylinder 204, and the annular groove 205 is slidably connected to the positioning ring 208.

[0023] The positioning ring 208 and the annular groove 205 work together to allow the internally threaded cylinder 202 to rotate stably on the fixed cylinder 204.

[0024] Furthermore, in the above structure, a servo motor 206 is installed on one side of the fixed cylinder 204, and a gear 207 is installed at the output end of the servo motor 206, and the gear 207 meshes with the gear ring 203.

[0025] The servo motor 206 can drive the gear 207 to rotate, which in turn drives the internal threaded cylinder 202 to rotate via the gear ring 203, thereby driving the internal threaded cylinder 202 to move.

[0026] Furthermore, in the above structure, the cleaning component 003 also includes a water intake cylinder 303, which is connected through to the bottom of the water pumping pipe 301. Multiple sets of filter tanks 304 are arranged in a ring on the inner wall of the water intake cylinder 303.

[0027] The filter tank 304 allows the water intake tube 303 to draw water into its interior, and the filter tank 304 can filter out foreign objects in the water.

[0028] Furthermore, in the above structure, a cleaning cylinder 308 is sleeved on the water intake cylinder 303, and multiple sets of cleaning rods 305 are installed in a ring on the inner wall of the cleaning cylinder 308, and the cleaning rods 305 are slidably connected to the corresponding filter tanks 304.

[0029] By moving the cleaning cylinder 308 up and down, the cleaning rod 305 slides inside the filter tank 304, thereby cleaning the filter tank 304 and preventing the filter tank 304 from becoming clogged during water absorption.

[0030] Furthermore, in the above structure, push rods 306 are symmetrically installed on one side of the cleaning cylinder 308, and a limiting ring 307 is fixedly sleeved on the sampling cylinder 001. The limiting ring 307 is connected through the push rod 306, and the push rod 306 is fixedly connected to one side of the fixed cylinder 204.

[0031] The limit ring 307 can guide the push rod 306. When the cleaning rod 305 moves into place inside the filter tank 304, the cleaning cylinder 308 moves continuously, which can drive the water pump pipe 301 to move, thereby achieving the effect of adjusting the length. The short-distance reciprocating motion of the internal threaded cylinder 202 can make the cleaning rod 305 reciprocate within the filter tank 304 in a short distance, achieving the cleaning effect and avoiding clogging.

[0032] The working principle of this practical application is as follows: Refer to the instruction manual appendix Figure 1-5 By inserting the sampling cylinder 001 into the target water area, a small water pump 101 draws water into the sampling cylinder 303 through the filter tank 304. Since the water enters the sampling cylinder 001 through the pumping pipe 301, the water sample is extracted. Simultaneously, the rotation of the servo motor 206 causes the gear 207 to drive the internally threaded cylinder 202 to rotate reciprocally via the gear ring 203, thus causing the fixed cylinder 204 to move reciprocally. This causes the push rod 306 to drive the cleaning rod 305 to move reciprocally within the filter tank 304 via the cleaning cylinder 308. The continuous movement of the internal threaded cylinder 202 causes the cleaning rod 305 to move into place within the filter tank 304, thereby causing the water sampling cylinder 303 to move the water pumping pipe 301 within the sampling cylinder 001. This changes the sampling length of the sampling device. This structure allows the sampling device to filter water while sampling and clean the filter area, effectively preventing impurities in the water from entering the device. Furthermore, this structure allows for effective adjustment of the sampling distance, greatly improving the practicality of the sampling device.

[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
