AI Technical Summary
Existing hydrogeological survey and sampling equipment is unable to effectively avoid surface water pollution, resulting in impure deep water samples.
A sampling bucket with supporting feet, valves, counterweight components, and sampling components was designed. By controlling the opening and closing of the water inlet, the sampling bucket is ensured to sink to a specified depth before sampling. Combined with an adjustable pull rope and flexible sleeve, adaptive sampling at different depths can be achieved.
This ensures that the inside of the sampling bucket does not come into contact with the surface water, guaranteeing the purity of deep water samples, and allows for adjustment of the sampling depth as needed, thus improving the adaptability of the device.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of hydrological sampling technology, specifically a hydrogeological survey water source sampling and testing device. Background Technology
[0002] In hydrogeological exploration, it is necessary to use devices to sample and test the water in the water area to ensure the accuracy of the exploration. Most existing sampling devices adopt the traditional barrel structure. When sampling targets at depths, a pull line and a weight are usually tied to the sampling barrel. The sampling barrel sinks under the action of the weight, and water enters the sampling barrel to complete the sampling.
[0003] However, during the above water sampling process, surface water will enter the sampling bucket first, making it difficult for the sampling bucket to obtain relatively pure deep water. In response to this situation, technological innovations will be carried out based on the existing hydrogeological exploration water sampling and testing devices. Utility Model Content
[0004] The purpose of this invention is to provide a water source sampling and testing device for hydrogeological exploration, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a hydrogeological exploration water source sampling and detection device, comprising:
[0006] A sampling bucket is provided, with its bottom evenly distributed on supporting feet. A valve is connected to the front of the sampling bucket, and a counterweight assembly is placed at the bottom. A water inlet is provided through the top of the sampling bucket, and a sampling component is placed on top of the bucket. A support frame is provided at the top of the sampling bucket, and a through hole is provided through the top of the support frame. An externally threaded sleeve is provided at the top of the support frame, corresponding to the through hole, which is aligned with the water inlet. Two sets of mounting holes are evenly distributed on the top of the sampling bucket.
[0007] Preferably, the counterweight assembly includes a screw, a counterweight disc is sleeved on the outer ring of the screw, and a nut is screwed onto the outer side wall of the screw.
[0008] Preferably, the screw is located at the bottom of the sampling barrel, and the nut is located at the bottom of the counterweight plate.
[0009] Preferably, the sampling assembly includes a pressure plate, with a set of spring telescopic rods on both the left and right sides of the bottom of the pressure plate. A sealing gasket is provided at the bottom of the pressure plate, located between the two sets of spring telescopic rods. A lifting ring is provided at the top of the pressure plate, with a spring hook hanging on the outer wall of the lifting ring. A pull rope is provided at the top of the spring hook, with a flexible sleeve placed around the outer ring of the pull rope. An internally threaded sleeve is provided at the bottom of the inner wall of the flexible sleeve, and a plastic handle is provided at the top of the outer wall of the flexible sleeve. A handle is provided at the top of the pull rope.
[0010] Preferably, the internal threaded sleeve is screwed onto the outer wall of the external threaded sleeve, and the pull rope is located in the through hole of the support frame, the size of which is larger than the size of the spring hook.
[0011] Preferably, the spring telescopic rod is installed in the mounting hole at the top of the sampling bucket, and the sealing gasket is installed at the top of the sampling bucket and corresponds to the water inlet.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] In this invention, the sampling bucket is submerged to a specified depth in the water source before the inlet is opened to take samples, thus ensuring that the inside of the sampling bucket cannot come into contact with the surface water, thereby ensuring the purity of the deep water sample.
[0014] After unlocking the spring hook, separate the inner threaded sleeve from the outer threaded sleeve by screwing them apart. This allows you to remove the pull rope and flexible sleeve. At this point, you can quickly replace the flexible sleeve and pull rope of different lengths according to the actual sampling depth requirements. After unscrewing the nut, you can freely add or remove the counterweight plate, which allows the sampling bucket to sink to different depths of water, thus ensuring the adaptability of the device.

Detailed Implementation
[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figures 1-3 A water source sampling and testing device for hydrogeological exploration includes a sampling bucket 1. The bottom of the sampling bucket 1 is evenly fixedly mounted on support feet 11. A valve 12 is connected to the front side of the sampling bucket 1. Opening the valve 12 allows the water source sample in the sampling bucket 1 to be discharged. A counterweight component is placed at the bottom of the sampling bucket 1. A water inlet is opened through the top of the sampling bucket 1. A sampling component is placed on the top of the sampling bucket 1. A support frame 33 is fixedly mounted on the top of the sampling bucket 1. A through hole is opened through the top of the support frame 33. A threaded sleeve 39 is fixedly installed on the top of the support frame 33, corresponding to the through hole, which is aligned with the water inlet. Two sets of mounting holes are evenly distributed on the top of the sampling bucket 1. The counterweight assembly includes a screw 2, with a counterweight plate 21 sleeved on the outer ring of the screw 2. A nut 22 is screwed onto the outer wall of the screw 2. The screw 2 is fixedly installed at the bottom of the sampling bucket 1, and the nut 22 is located at the bottom of the counterweight plate 21. The counterweight plate 21 can pull the sampling bucket 1 to sink into the water. After unscrewing the nut 22, the counterweight plate 21 can be added or removed freely, allowing the sampling bucket 1 to sink to different depths of water, thus ensuring the adaptability of the device. The sampling assembly includes a pressure plate 34, with a set of spring telescopic rods 36 fixedly installed on both the left and right sides of the bottom of the pressure plate 34. A sealing gasket 35 is fixedly installed at the bottom of the pressure plate 34, located between the two sets of spring telescopic rods 36. A lifting ring 37 is fixedly installed on the top of the pressure plate 34. A spring hook 38 is hung on the outer wall of the lifting ring 37. A pull rope 31 is fixedly installed on the top of the spring hook 38. A flexible sleeve 3 is placed on the outer ring of the pull rope 31. An internally threaded sleeve 391 is fixedly installed at the bottom of the inner wall of the flexible sleeve 3. A plastic sleeve handle 392 is fixedly installed on the top of the outer wall of the flexible sleeve 3. A handle 32 is fixedly installed on the top of the pull rope 31. The internally threaded sleeve 391 is screwed into the outer wall of the externally threaded sleeve 39. The pull rope 31 is located in the through hole of the support frame 33. The size of the through hole is larger than the size of the spring hook 38. A spring telescopic rod 36 is fixedly installed in the mounting hole on the top of the sampling bucket 1. A sealing gasket 35 is slidably installed on the top of the sampling bucket 1 and corresponds to the water inlet. The spring telescopic rod 36 uses the elastic force of its internal spring to make the pressure plate 34 seal the water inlet of the sampling bucket 1 through the sealing gasket 35.
[0021] Working principle: The spring telescopic rod 36 uses the elastic force of its internal spring to seal the water inlet of the sampling bucket 1 through the sealing gasket 35 with the pressure plate 34. The counterweight plate 21 can pull the sampling bucket 1 into the water. At this time, the flexible sleeve 3 is straightened due to the weight of the counterweight plate 21. The user holds the plastic sleeve handle 392 with one hand and pulls the handle 32 with the other hand. The handle 32 drives the pull rope 31 to move up and down, which in turn drives the pressure plate 34 to move upward through the spring hook 38 and the lifting ring 37. When the sealing gasket 35 at the bottom of the pressure plate 34 separates from the water inlet of the sampling bucket 1, the water source can flow into the sampling bucket 1, thus completing the sampling. When the handle 32 is released, the spring telescopic rod 36 uses its own rebound force to drive the pressure plate 34 to move downward and reset, thus making the sampling bucket 1 lower. The sealing gasket 35 re-seales the inlet of the sampling bucket 1. Since the sampling bucket 1 is submerged to a specified depth in the water source before sampling begins, this ensures that the inside of the sampling bucket 1 cannot come into contact with the surface water, thereby ensuring the purity of the deep water sample. Opening the valve 12 allows the water sample in the sampling bucket 1 to be discharged. After unlocking the spring hook 38, the inner threaded sleeve 391 and the outer threaded sleeve 39 are spirally separated, allowing the pull rope 31 and the flexible sleeve 3 to be removed. At this point, flexible sleeves 3 and pull ropes 31 of different lengths can be quickly replaced according to the actual depth sampling requirements. After unscrewing the nut 22, the counterweight plate 21 can be freely added or removed, allowing the sampling bucket 1 to be submerged in water of different depths, thus ensuring the adaptability of the device.
