Description

Technical Field

[0001] The present application relates to the technical field of water source sampling, and more specifically, to a mobile water source sampler for water conservancy projects and a method of using the same. Background Art

[0002] In order to detect the water quality, it is necessary to use a water source sampler to sample the water source in the water area.

[0003] The document with the prior art publication number CN219084454U provides a mobile water source sampler for water conservancy projects. The device fixes ropes on both sides of the sampling barrel and on the buckle respectively, lowers the rope connected to the sampling barrel first, and pulls out the sealing plate with the rope connected to the buckle. When the lifting bar is stuck by the limiter, the space inside the barrel is sealed, and the sampling barrel is placed in the water. After reaching the specified position, the rope on the buckle is released, and the air compression plate, the lifting bar and the sealing plate return to their original positions under the action of the winding spring. The air in the barrel and the water outside the barrel interact with each other through the air groove and the filter plate, and the water is sucked into the barrel to achieve accurate sampling of the water source at the specified depth.

[0004] Although the above-mentioned prior art solution can achieve accurate sampling of water sources at a specified depth through the structure of the prior art, it still has the following defects: when the device is used, when sampling water areas with a wider surface, the device is not convenient for sampling water sources in distant water areas, resulting in a limited sampling range and insufficient sampling data.

[0059] Reference Figure 1-Figure 6 , a method for using a mobile water source sampler for a water conservancy project, comprising the following steps:

[0060] S1. According to the distance of the water intake position, the adjusting device is adjusted by rotating the worm 101 to adjust the angle of the adjusting frame 3 and the extension length of the adjusting rod 503;

[0061] S2, then use the electric push rod 401 to drive the connected rack 402 to move, so that the toggle rod 404 drives the adjustment rod 503 to move the ejection seat 501;

[0062] S3, when the toggle rod 404 is separated from the adjustment rod 503, the ejection seat 501 moves quickly under the action of the spring 502;

[0063] S4, then the floating seat 6 will float on the water surface, and then the motor A601 will drive the sampling mechanism 7 connected with the sampling rope 602 to go deep into the water body;

[0064] S5. Then use the motor B702 to drive the sampling bottle 704 on the connected placement seat 703 to rotate. At this time, when the sealing head 705 contacts the extrusion plug 708, it will move down, so that the opening of the sampling bottle 704 is conductive. At this time, the water at this depth will fall into the sampling bottle 704 for sampling. After the sampling is completed, rotate the wire rack 2 and pull the connected floating seat 6 back.

[0065] The implementation principle of a mobile water source sampler for water conservancy projects in the embodiment of the present application is as follows: when water source sampling is required, the device is moved to the shore of the water source, and then the device is adjusted according to the distance of the water sampling location, and the angle of the adjustment frame 3 connected to the worm gear 301 is adjusted by rotating the worm 101, and the adjustment rod 503 is rotated at the same time to adjust the extension length of the adjustment rod 503;

[0066] Then, the electric push rod 401 drives the connected rack 402 to move, so that the rack 402 drives the toggle rod 404 connected to the gear 403 to rotate, so that the toggle rod 404 drives the adjustment rod 503 to move the ejection seat 501;

[0067] Then, when the toggle rod 404 is separated from the adjustment rod 503, the ejection seat 501 will move quickly under the action of the spring 502, and the floating seat 6 will be ejected to the water area to be sampled;

[0068] Then the floating seat 6 will float on the water surface, and then the motor A601 will drive the sampling mechanism 7 connected to the sampling rope 602 to go deep into the water body to reach a suitable depth;

[0069] Then, the motor B702 is used to drive the connected placement seat 703 to rotate, so that the sampling bottle 704 on the placement seat 703 rotates accordingly. At this time, when the sealing head 705 contacts the extrusion plug 708, the sealing head 705 will move down, so that the opening of the sampling bottle 704 is conductive. At this time, water at this depth will fall into the sampling bottle 704 for sampling. After sampling, the wire rack 2 is rotated to pull the connected floating seat 6 back.
