Description

Technical Field

[0001] This utility model relates to the field of hydrogeological survey technology, and in particular to a monitoring device for hydrogeological surveys. Background Technology

[0002] The fixed-depth sampling device is used to accurately collect groundwater samples at specific depths. Its core function is to prevent the mixing of water from different aquifers and ensure that the sample accurately reflects the hydrogeochemical characteristics of the target depth. This device is widely used in stratified water quality monitoring, pollution source tracing, and groundwater dynamics research.

[0003] A common sampling method involves placing the sampling pipe at the target depth, first extracting the preceding mixed water, and then collecting the water sample after it has stabilized. If the extraction time is insufficient or the flow rate is inappropriate, residual mixed water may contaminate the target water sample, leading to distorted test data. Utility Model Content

[0004] Therefore, it is necessary to provide a monitoring device for hydrogeological surveys to address the problem that monitoring and sampling devices used in hydrogeological surveys have difficulty accurately sampling water samples at corresponding depths, which increases subsequent detection errors.

[0005] A monitoring device for hydrogeological surveys, comprising:

[0006] A monitoring and sampling mechanism, comprising a controller, a waterproof wire, a waterproof solenoid valve, and a threaded sampling bottle, wherein the controller and the waterproof solenoid valve are electrically connected via the waterproof wire;

[0007] An adjustable connection mechanism includes a three-way threaded pipe and at least two extension rods. The waterproof solenoid valve and the threaded sampling bottle are symmetrically threaded to two opposite openings of the three-way threaded pipe. The top of the extension rod has a threaded groove, and the bottom of the extension rod is fixedly connected to a threaded post. The lowest threaded post is threadedly connected to the last opening of the three-way threaded pipe, and the remaining threaded posts are threadedly connected to the adjacent lower threaded groove.

[0008] In one embodiment, the waterproof wire is spiral-shaped and spirally wraps around the surface of the extension rod.

[0009] In one embodiment, the surface of the extension rod has openings that are staggered with the threaded grooves, and the corners of the openings are rounded.

[0010] In one embodiment, the surface of the extension rod is provided with graduations that are staggered with the opening, and the graduation value of the graduations is cm.

[0011] In one embodiment, the three-way threaded tube has an overflow port on its surface near the threaded sampling bottle. The adjustable connection mechanism also includes a drainage component, which includes a round rod rotatably connected inside the three-way threaded tube. Both ends of the round rod extend through the three-way threaded tube, and a sealing plate that contacts the overflow port is fixedly connected to one end of the round rod.

[0012] In one embodiment, the sealing sheet includes a stainless steel inner layer and a rubber outer layer, the rubber outer layer being fitted over the surface of the stainless steel inner layer, and one end of the rubber outer layer sealing the overflow port.

[0013] In one embodiment, a knob is fixedly connected to the other end of the round rod, and the corners of the knob are rounded.

[0014] In one embodiment, the surface of the knob has a circular hole, and an elastic rope that is fixedly connected to a three-way threaded tube is inserted into the inside of the circular hole.

[0015] Beneficial effects

[0016] The aforementioned monitoring device for hydrogeological surveys uses an adjustable connection mechanism with an extension rod combination and scale to precisely control the sampling depth. Combined with the remote opening and closing of a waterproof solenoid valve, it enables pinpoint sampling of the target water layer. The sealed connection between the threaded sampling bottle and the three-way threaded pipe ensures that the water sample comes only from the target depth, effectively solving the problem that existing monitoring and sampling devices for hydrogeological surveys have difficulty in accurately sampling water samples at the corresponding depth.

[0017] The monitoring and sampling mechanism and the adjustable connection mechanism adopt a standardized interface of threaded post and threaded groove, which supports flexible addition or reduction of the number of extension rods according to sampling needs. The waterproof wire spiral winding design facilitates synchronous extension and retraction with the extension rod, and the controller has a built-in power supply to provide portable power to the solenoid valve. The entire device can be quickly assembled, sampled, and disassembled and retrieved, significantly improving the efficiency of field operations. Attached Figure Description

[0031] The following is combined Figures 1-5 This invention describes a monitoring device for hydrogeological surveys.

[0032] In one embodiment, a monitoring device for hydrogeological surveys includes:

[0033] The monitoring and sampling mechanism 100 includes a controller 110, a waterproof wire 120, a waterproof solenoid valve 130, and a threaded sampling bottle 140. The controller 110 and the waterproof solenoid valve 130 are electrically connected through the waterproof wire 120. The controller 110 has a built-in ACASIS 300W portable energy storage power supply (ACASIS AS300); power supply capacity: supports AC 100~240V AC output (maximum 300W).

[0034] The waterproof wire 120 is spiral in shape and is spirally wrapped around the surface of the extension rod 220.

[0035] like Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the adjustable connection mechanism 200 includes a three-way threaded pipe 210 and at least two extension rods 220. The waterproof solenoid valve 130 and the threaded sampling bottle 140 are symmetrically threaded to two opposing openings of the three-way threaded pipe 210. The top of the extension rod 220 has a threaded groove 221, and the bottom of the extension rod 220 is fixedly connected to a threaded post 230. The lowest threaded post 230 is threadedly connected to the last opening of the three-way threaded pipe 210, and the remaining threaded posts 230 are threadedly connected to the adjacent lower threaded groove 221. The surface of the extension rod 220 has openings 222 that are staggered with the threaded grooves 221, and the corners of the openings 222 are rounded. The surface of the extension rod 220 has scales 223 that are staggered with the openings 222, and the scales 223 have a graduation value of 1 cm.

[0036] like Figure 3 , Figure 4 and Figure 5 As shown, the three-way threaded tube 210 has an overflow port 211 on its surface near the threaded sampling bottle 140. The adjustable connection mechanism 200 also includes a drainage assembly 240. The drainage assembly 240 includes a round rod 241 rotatably connected inside the three-way threaded tube 210. Both ends of the round rod 241 extend through the three-way threaded tube 210. One end of the round rod 241 is fixedly connected to a sealing plate 242 that contacts the overflow port 211. The sealing plate 242 includes a stainless steel inner layer and a rubber outer layer. The rubber outer layer is fitted onto the surface of the stainless steel inner layer, and one end of the rubber outer layer seals the overflow port 211. The other end of the round rod 241 is fixedly connected to a knob 243. The knob 243 has rounded corners. The surface of the knob 243 has a round hole 244. An elastic rope 245 fixedly connected to the three-way threaded tube 210 is inserted into the round hole 244.

[0037] Working principle: Installation before sampling: Select the corresponding number of extension rods 220 according to the sampling depth requirements, and form a long rod with matching depth by connecting the first and last threads of the threaded post 230 and the threaded groove 221; thread the upward opening of the three-way threaded tube 210 to the bottom threaded post 230; thread the threaded sampling bottle 140 and the waterproof solenoid valve 130 to the two opposite openings of the three-way threaded tube 210 respectively; spirally wrap the waterproof wire 120 around the surface of the extension rod 220, and connect the two ends to the controller 110 and the waterproof solenoid valve 130 respectively.

[0038] Depth sampling: The three-way threaded pipe 210, together with the waterproof solenoid valve 130 and the threaded sampling bottle 140, is placed at the target water depth via the extension rod 220. The waterproof solenoid valve 130 is opened via the controller 110 to allow water to enter the threaded sampling bottle 140 through the three-way threaded pipe 210. After the sampling bottle is full, the waterproof solenoid valve 130 is closed and the device is removed.

[0039] Disassembly and assembly: Place the threaded sampling bottle 140 vertically, turn the knob 243 to drive the sealing plate 242 through the round rod 241 to open the overflow port 211 to discharge excess water; unscrew the threaded sampling bottle 140 with sufficient sample and seal it with the threaded cap; disassemble and recycle the remaining structure by reversing the installation steps before sampling.

[0040] It should be noted that the controller 110, waterproof wire 120, waterproof solenoid valve 130, and threaded sampling bottle 140 mentioned above are all devices with relatively mature existing technology. The specific models can be selected according to actual needs. At the same time, the controller 110 and waterproof solenoid valve 130 are both powered by built-in power supplies, which will not be described in detail here.

[0041] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0042] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
