DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] The following is combined with Figure 1 The specific implementation modes of the present utility model are further described in detail.

[0019] In this embodiment, by Figure 1 As shown, the utility model includes a collection frame 1, on which a collection disk 2 is rotatably arranged, on which a driving assembly is arranged, a collection box 3 is fixed at the output end of the driving assembly, and the driving assembly can adjust the height of the collection box 3, a plurality of collection plates 5 are sealed in the collection box 3, and the interior of the collection box 3 is divided into a plurality of collection areas 4 by the collection plates 5, and a plurality of collection doors 6 corresponding to the collection areas 4 are arranged on the collection box 3, and each of the collection doors 6 is installed with a control assembly for controlling the opening and closing of each collection area 4, and the collection box 3 is provided with a plurality of collection doors 6 corresponding to the collection areas 4, and each of the collection doors 6 is installed with a control assembly for controlling the opening and closing of each collection area 4. A bottom shell 7 is rotatably provided, and a thread is provided on the bottom shell 7. The inner wall at the bottom of the collection box 3 is provided with a thread groove that meshes with the thread on the bottom shell 7. The bottom shell 7 can be installed on the collection box 3 by rotating in cooperation with the thread and the thread groove. The driving component is used to adjust the height of the collection box 3. The control component is used to control the opening and closing of the collection door 6 for collecting water samples. In one sampling, each time a different depth is reached, a collection door 6 can be opened and a collection area 4 can be used for sampling. In this way, water samples of multiple depths can be collected through multiple collection areas 4, thereby improving the collection efficiency.

[0020] In this embodiment, by Figure 1 As shown, a placing rack 8 is fixed on the collecting rack 1 , a placing platform 9 is fixed on the placing rack 8 , and the driving assembly is fixed on the placing rack 8 .

[0021] In this embodiment, by Figure 1As shown, the driving assembly includes a driving motor 10 fixed on the placement frame 8, and the output end of the driving motor 10 is fixed with a storage shaft 11 rotatably mounted on the placement frame 8, and a traction rope 12 is wound around the storage shaft 11. The collection box 3 is fixed on the traction rope 12. The driving motor 10 drives the storage shaft 11 to rotate, and the forward and reverse rotation of the driving motor 10 is controlled to control the retraction and extension of the traction rope 12, thereby controlling the depth of the collection box 3 entering the water.

[0022] In this embodiment, by Figure 1-2 As shown, the collection box 3 is provided with a plurality of collection slots 13 connected with the collection area 4, and each of the collection doors 6 is slidably arranged in the collection slot 13 through sliding slots arranged on the collection box 3 on both sides of the collection slot 13. A plurality of springs 14 are arranged in each of the collection slots 13, and one end of each of the springs 14 is fixed to the inner wall of the corresponding collection slot 13, and the other end of each of the springs 14 is fixed to the corresponding collection door 6. Usually, the collection door 6 is pushed by the spring 14, and the uppermost side of the collection slot is in a closed state, and is opened by the control component, and is closed by the cooperation between the control component and the spring 14.

[0023] In this embodiment, by Figure 1-2 As shown, the control component includes a rotating column 15 rotatably mounted on the collection disk 2, a handle 16 is fixed on the rotating column 15, a collection rope 17 is wound on the rotating column 15, one end of the collection rope 17 is fixed with a fixed block 18, the fixed block 18 is fixed to the corresponding collection door 6, the collection rope 17 passes through a plurality of pulleys 19, and the plurality of pulleys 19 are rotatably mounted on the placement table 9 and the collection box 3 respectively. When the driving motor 10 drives the collection box 3 to descend, the collection door 6 is supported by the spring 14, and the collection rope 17 will pull the rotating column 15 to rotate while the collection box 3 descends, so that the collection rope 17 is released. When it is necessary to open the corresponding collection door 6, the collection rope 17 passes through a plurality of pulleys 19, and the plurality of pulleys 19 are rotatably mounted on the placement table 9 and the collection box 3 respectively. When the driving motor 10 runs and drives the collection box 3 to descend, the collection door 6 is supported by the spring 14, and the collection rope 17 will pull the rotating column 15 to rotate while the collection box 3 descends, so that the collection rope 17 is released. When the collection door 6 is used to collect water samples, the collection rope 17 is rolled up by rotating the handle 16 corresponding to the collection door 6 to pull the collection door 6 down and open. After the collection is completed, the handle 16 is released, and the spring 14 pushes the collection door 6 to close. The spring 14 here is selected to have a large elasticity. Because the collection box 3 is too heavy as a whole, rotating the handle 16 will only pull the collection door 6 down and will not drive the collection box 3 to rise. After the collection is completed, the collection box 3 is driven to rise by the driving motor 10 to collect water samples. When the collection box 3 is reset, the collection rope 17 can be rolled up by rotating the handle 16. Similarly, the handle 16 can be replaced with an electric device for electric control, such as a motor.

[0024] In this embodiment, by Figure 1As shown, a block 20 plugged into the collection box 3 is provided below each of the collection areas 4. After collecting the water sample, the bottom shell 7 is rotated to open, and then the container for collecting the water sample is placed under the corresponding block 20, and the block 20 is rotated to open so that the collected water sample flows out for collection.

[0025] In this embodiment, by Figure 1 As shown, a plurality of elastic blocks 21 are fixed on the collection plate 2, each of the elastic blocks 21 is provided with an elastic groove, and each of the collection ropes 17 passes through a corresponding elastic groove, and the elastic groove is an arc-shaped groove. The elastic groove is used to increase the friction between the collection rope 17 and the elastic block 21, so as to prevent the collection rope 17 from directly driving the rotating column 15 to rotate with gravity, and to prevent the collection rope 17 from automatically dispersing. When the collection box 3 stops moving downward, the collection rope 17 will not continue to drive the rotating column 15 to rotate, thereby facilitating the subsequent control of the collection door 6.

[0026] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
