Description

Technical Field

[0001] The utility model relates to the technical field of water sampling equipment, and particularly relates to a water sampling device with adjustable depth. Background Art

[0002] With the increasing importance of water resource protection and environmental monitoring, accurate sampling of water bodies has become a key task. In actual water sampling work, it is often necessary to sample and analyze water bodies at different depths to comprehensively understand the quality of water bodies. However, existing water sampling devices often have the problem of fixed sampling depth, which cannot meet the need for accurate sampling of water bodies at different depths, greatly limiting the sampling range and applicable scenarios.

To solve the above problems, we propose a water sampling device with adjustable depth. Content of the Utility Model

During use, the adjusting component 3 lowers the counterweight 5. Under the influence of its own gravity, the counterweight 5 drives the sliding column 4 to move downward along the guiding column 2, and the counterweight 5 drives the sampling component 6 to move downward. There are scales engraved on the guiding column 2. When the sliding column 4 moves to the required depth, the adjusting component 3 stops moving the counterweight 5. During sampling, the sampling device is inserted into the water body, and the floating board 1 drives the device to float on the water surface to prevent the device from falling into the water. The sampling component 6 samples the water body. By setting the adjusting component 3, the position of the sampling component 6 can be adjusted, facilitating the sampling device to sample water bodies at different depths. By setting the sampling component 6, water samples can be collected, preventing water from other depths from entering the sampling device and avoiding mixing water from other depths in the sample, which may affect the sampling result.

[0023] The adjusting component 3 includes a wire reel 31, the bottom of the wire reel 31 is fixedly connected to the top of the floating board 1, a motor 32 is fixedly installed on the outer side of the wire reel 31, a cable 33 is slidably connected to the outer side of the wire reel 31, and one end of the cable 33 away from the wire reel 31 is fixedly connected to the top of the counterweight 5. During use, the motor 32 in the adjusting component 3 is started, and the motor 32 drives the rotating rod on the wire reel 31 to rotate. The rotating rod drives the cable 33 to wind and unwind. The counterweight 5 is restricted by the cable 33. When the wire reel 31 winds the cable, the counterweight 5 is driven by the cable 33 to move upward. When the wire reel 31 unwinds the cable, the cable 33 is in a slack state, and the counterweight 5 moves downward under the influence of gravity. By setting the adjusting component 3, the position of the sampling component 6 can be adjusted, the depth of water sampling can be adjusted, facilitating the sampling device to sample water bodies at different depths, expanding the sampling range of the sampling component 6, and improving the applicable range of the sampling device.

[0024] The sampling assembly 6 includes a fixing plate 61. The outer side of the fixing plate 61 is fixedly connected to the side of the counterweight block 5 away from the sliding column 4. The outer side of the fixing plate 61 is fixedly connected with a limiting frame 62. The inner side of the limiting frame 62 is fixedly connected with an elastic plate 63. During use, the sampling bottle is inserted into the limiting frame 62 on the fixing plate 61. The sampling bottle drives the elastic plate 63 to bend and deform. Driven by its own elastic force, the elastic plate 63 presses on the surface of the sampling bottle to fix the sampling bottle. By setting the elastic plate 63, it is convenient to fix the sampling bottle, convenient to take out the sampling bottle, and convenient to take out the sample.

[0025] The outer side of the elastic plate 63 is slidably connected with a sampling bottle assembly 64. The outer side of the sampling bottle assembly 64 is fixedly connected with a water inlet assembly 65. During sampling, the sampling bottle assembly 64 extends into the water body. The air pump 7 pumps out the gas in the sampling bottle assembly 64, so that the external water body enters the sampling bottle assembly 64 through the water inlet assembly 65. By setting the sampling assembly 6, the water body is sampled. After sampling, the water inlet assembly 65 is used to seal the sampling bottle assembly 64 to prevent water bodies at other depths from entering the sampling bottle assembly 64 during the rising process, which affects the sampling result.

[0026] The sampling bottle assembly 64 includes a bottle body 641. The outer side of the bottle body 641 is slidably connected with the outer side of the elastic plate 63. The top of the bottle body 641 is threadedly connected with a sealing cap 642. The top of the sealing cap 642 is fixedly connected with an air pipe 643. The top end of the air pipe 643 is fixedly connected to the outer side of the air pump 7. During use, a sealing ring is provided between the sealing cap 642 and the bottle body 641. Along the thread on the bottle body 641, the sealing cap 642 is tightened to connect the air pipe 643 to the air pump 7. During sampling, the air pump 7 pumps out the gas in the bottle body 641, the air pressure in the bottle body 641 becomes smaller, and the external water body enters the inside of the bottle body 641 along the water inlet assembly 65. By setting the sampling bottle assembly 64, the air is pumped out by the air pump 7 to control the sampling of the bottle body 641, preventing the sampling bottle assembly 64 from sampling water bodies at other depths.

[0027] The water inlet assembly 65 includes a water inlet pipe 651. The outer side of the water inlet pipe 651 is fixedly connected to the outer side of the bottle body 641. An installation plate 652 is fixedly connected to the inner side of the water inlet pipe 651. A blocking rod 653 is slidably connected to the inner side of the installation plate 652. A compression spring 654 is sleeved on the outer side of the blocking rod 653. During use, the compression spring 654 drives the blocking rod 653 to closely adhere to the inner side of the water inlet pipe 651. During the process of extending into the water body, since there is air in the bottle body 641, it is difficult for the external water body to push the compression spring 654, and the water inlet assembly 65 is in a sealed state. During sampling, the air pump 7 pumps out some of the gas in the bottle body 641, the air pressure in the bottle body 641 becomes smaller, the external water body pushes the blocking rod 653, the blocking rod 653 approaches the installation plate 652, the blocking rod 653 drives the compression spring 654 to compress, and the external water body flows into the bottle body 641 along the gap between the blocking rod 653 and the water inlet pipe 651. After the pressure inside and outside the bottle body 641 is balanced, the compression spring 654 drives the blocking rod 653 to block the water inlet pipe 651. By setting the water inlet assembly 65, the entry of the external water body is controlled to avoid sampling unnecessary water bodies and prevent the water bodies at other depths from contaminating the samples.

The sampling bottle assembly 64 drives the elastic plate 63 to bend and deform. Driven by its own elastic force, the elastic plate 63 presses on the surface of the sampling bottle assembly 64 to fix the sampling bottle assembly 64.

[0030] During adjustment, the motor 32 in the adjustment assembly 3 is started. The motor 32 drives the rotating rod on the wire reel 31 to rotate, the wire reel 31 pays out the wire, the cable 33 is in a slack state, and the counterweight 5 moves downward under the influence of gravity. Under the influence of its own gravity, the counterweight 5 drives the sliding column 4 to move downward along the guiding column 2. The counterweight 5 drives the sampling assembly 6 to move downward. Scales are engraved on the guiding column 2. When the sliding column 4 moves to the required depth, the motor 32 stops moving, and the cable 33 is in a taut state to fix the counterweight 5 at this depth.

[0031] The sampling device is extended into the water body. The floating plate 1 drives the device to float on the water surface, and the sampling bottle assembly 64 extends into the water body. During the process of extending into the water body, the compression spring 654 drives the blocking rod 653 to closely adhere to the inner side of the water inlet pipe 651. Since there is air in the bottle body 641, it is difficult for the external water body to push the compression spring 654, and the water inlet assembly 65 is in a sealed state.

[0032] During sampling, the air pump 7 extracts part of the gas in the bottle body 641, the air pressure in the bottle body 641 decreases, the external water body pushes the blocking rod 653, the blocking rod 653 approaches the mounting plate 652, the blocking rod 653 drives the compression spring 654 to compress, and the external water body flows into the inside of the bottle body 641 along the gap between the blocking rod 653 and the water inlet pipe 651. After the pressure inside and outside the bottle body 641 is balanced, the compression spring 654 drives the blocking rod 653 to block the water inlet pipe 651.
