[0004] Based on the above retrieval and combined with the existing technology, it is found that the structure of the multi-depth water quality sampling device similar to the above disclosure in the existing technology is relatively complex, and a rigid connecting piece is used between adjacent collecting buckets, resulting in a relatively small adjustable range and inconvenient multi-depth sampling of water layers with a large depth range. Therefore, a multi-depth water quality sampling device is proposed to improve the above problems. Content of the Utility Model

A water passing hole is provided at one side end of the sampling cylinder, and a sealing cover plate is provided at the water passing hole. The sealing cover plate is located outside the sampling cylinder, and an elastic resetting member is installed between the sampling cylinder and the sealing cover plate;

[0008] A telescopic component is arranged inside the sampling cylinder. The telescopic component includes a sleeve and a sliding rod. One end of the sleeve fixedly penetrates through one side of the sampling cylinder away from the water passing hole and is fixedly communicated with the other end of the air guide hose.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0023] Embodiment: Refer to Figures 1-4 A multi-depth water quality sampling device as shown, including a connecting rope 1 and a sampling cylinder 2, further including an air guide hose 3. One end of the air guide hose 3 is installed with an air pump (not shown in the figure). A connecting ring 201 for fastening the connecting rope 1 is installed at the side end of the sampling cylinder 2. A water passing hole is provided at one side end of the sampling cylinder 2, and a sealing cover plate 4 is provided at the water passing hole. The sealing cover plate 4 is located outside the sampling cylinder 2. An elastic reset member is installed between the sampling cylinder 2 and the sealing cover plate 4. A telescopic assembly 5 is provided inside the sampling cylinder 2. The telescopic assembly 5 includes a sleeve 51 and a slide bar 52. One end of the sleeve 51 is fixedly penetrated through the side of the sampling cylinder 2 away from the water passing hole and is fixedly communicated with the other end of the air guide hose 3. The slide bar 52 is slidably sleeved inside the sleeve 51, and the sealing cover plate 4, the sleeve 51 and the slide bar 52 are coaxially arranged.

[0024] Based on the cooperative setting of the above structure, the air pump can be used to blow air through the air guide hose 3, so that the sliding rod 52 slides towards the outside of the sleeve 51. The sliding rod 52 sliding outwards will push the sealing cover plate 4 outwards. At this time, the external water enters the sampling cylinder 2 through the water passing holes. After that, the air pump is used to suck air, and the sealing cover plate 4 will reset to seal the water passing holes under the action of the elastic reset member, realizing sampling. The structure is simple, the operation is convenient, and the practicability is stronger.

[0025] Among them, the elastic reset member includes a tension spring 7. An installation frame 6 is installed on the inner wall of the sampling cylinder 2, and the tension spring 7 is fixed between the installation frame 6 and the sealing cover plate 4.

[0026] In order to ensure the stable sealing performance of the sealing cover plate 4, the diameter of the sealing cover plate 4 is larger than the aperture of the water passing hole. A sealing ring 401 is installed on the end face of the sealing cover plate 4 close to the sampling cylinder 2, and a pull ring 402 is installed on the end face of the sealing cover plate 4 far from the sampling cylinder 2. The pull ring 402 facilitates the operator to open the sealing cover plate 4 to remove the sampled water later.

[0027] Among them, as Figure 4 shown, a limiting sliding groove 5101 is provided on the inner side of the sleeve 51. A limiting sliding block 5201 adapted to the limiting sliding groove 5101 is integrally provided at the end of the sliding rod 52 located inside the sleeve 51, effectively preventing the sliding rod 52 from detaching from the sleeve 51.

[0028] Among them, a plurality of sampling cylinders 2 are provided, and the plurality of sampling cylinders 2 are sequentially fixed to the connecting rope 1 from top to bottom through connecting rings 201, and the sleeves 51 on the plurality of sampling cylinders 2 are fixedly communicated with the air guide hose 3. The distance between two adjacent sampling cylinders 2 can be adjusted according to different sampling depth ranges, realizing simultaneous sampling of water layers at multiple depths, and the operation is more convenient.

[0029] The working principle of the present utility model: Adjust the distance between two adjacent sampling cylinders 2 according to different sampling depth ranges. After placing the sampling cylinder 2 into the water layer to be sampled, use the air pump to blow air through the air guide hose 3, so that the sliding rod 52 slides towards the outside of the sleeve 51. The sliding rod 52 sliding outwards will push the sealing cover plate 4 outwards, and the tension spring 7 is stretched. At this time, the external water enters the sampling cylinder 2 through the water passing holes. After that, use the air pump to suck air, and the sealing cover plate 4 will reset to seal the water passing holes under the action of the tension spring 7, realizing simultaneous sampling of water layers at multiple depths. The structure is simple, the operation is convenient, and the practicability is stronger.

[0030] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
