Abstract
Description
Technical Field
[0001] The present application relates to the technical field of water conservancy projects, and in particular to a water quality sampling device for multi-layer water areas. Background Art
[0002] Water conservancy projects are projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and promoting benefits. In water conservancy projects, in order to better understand the water quality of the water area, it is necessary to use sampling devices to sample the water body for subsequent water quality testing.
[0003] Currently, water quality sampling devices include a guide slide, a control rod, and several sampling bottle mechanisms. When sampling, the sampling bottle mechanism is operated by the control rod to collect water samples at different depths. However, the sampling device collects water samples at a specific location, and pollutants in water are often distributed at different depths of the water body. Therefore, when it is necessary to obtain water samples at different depths, multiple collections are required. On the one hand, repeated operations will make the sampling work cumbersome. On the other hand, the longer the interval between the first sampling and the last sampling, the more difficult it is for the test results to accurately reflect the water quality at a certain point in time. This application proposes another technical solution to solve this technical problem. Utility Model Content
[0004] In order to quickly sample water quality at different depths at the same location, the present application provides a water quality sampling device for multi-layer water areas.
[0005] The present application provides a water quality sampling device for multi-layer water areas using the following technical solutions:

[0009] The driving unit is used to drive the water baffle to rotate.
[0010] By adopting the above technical solution, the water tanks are connected together using a connecting unit and placed in water. At this point, each water tank is located in the water at different depths at the same location. The driving unit drives the water baffle to rotate, opening the water inlet of the water tank, and water enters the water tank through the water inlet, thereby achieving rapid sampling of water quality at different depths at the same location. After water is drawn, the driving unit drives the water baffle to rotate until the water inlet is closed.

The connecting rod has the effect of connecting the various water intake tanks.
[0021] Optionally, the drive unit includes a base and a motor fixed on the base; the connecting rod and the base are threadedly connected, and a keyway is provided on the output shaft of the motor.

[0022] By adopting the above technical solution, when the connecting rod and the machine base are threadedly connected, the connecting key on the transmission shaft can be inserted into the keyway on the motor output shaft, so that when the output shaft of the motor rotates, the transmission shaft is driven to rotate, the transmission shaft drives the rotating shaft, and the rotating shaft drives the water baffle to rotate, thereby controlling the opening and closing of the water inlet hole.
[0023] In summary, this application includes at least one of the following beneficial technical effects:
[0024] 1. Connect the water tanks together using the connection unit and place them in water. Each tank is located at the same location but at different depths.

[0031] The technical solution in this application is further described in detail below with reference to the accompanying drawings.
[0032] The present application discloses a water quality sampling device for multi-layer water area. Figure 1 A water quality sampling device for multi-layer water areas includes a water intake unit 1, a connecting unit 2 and a driving unit 3.
[0033] For details, please refer to Figure 2 and Figure 3 The water intake unit 1 includes a water intake tank 11 and a water baffle 12 rotatably arranged in the water intake tank 11. The water intake tank 11 is a hollow cylindrical structure, and a water inlet hole 111 is opened on the water intake tank 11 for the water to be sampled to enter the water intake tank 11. A plug is threadedly connected to the water intake tank 11, and the water in the water intake tank 11 can be poured out by unscrewing the plug. It should be understood that a sealing layer is fixedly provided on the water baffle 12, and the sealing layer is made of rubber. In the initial position, the water baffle 12 rests on the inner wall of the water intake tank 11, thereby closing the water inlet hole 111 and preventing water from entering the water intake tank 11. The connecting unit 2 is used to connect adjacent water intake tanks 11. When sampling waters of different depths, the staff can install the connecting unit 2. The driving unit 3 is used to drive the water baffle 12 to rotate. When the water intake tank 11 is at the sampling depth of the water area, the water baffle 12 can be moved away under the action of the driving unit 3, allowing water to enter the water intake tank 11 from the water inlet 111.
[0034] Please refer to Figure 3 and Figure 4 A rotating shaft 13 is rotatably provided in the water intake tank 11, and a sleeve 14 is fixedly provided on the rotating shaft 13. A connecting rod 15 is slidably provided in the sleeve 14, and the end of the connecting rod 15 away from the sleeve 14 is fixedly connected to the water baffle 12. An elastic member is provided on the sleeve 14, and the specific function of the elastic member is to push the water baffle 12 to move toward the direction close to the water intake tank 11. In this embodiment, the elastic member is a spring 16, one end of the spring 16 is fixedly connected to the water baffle 12, and the other end of the spring 16 is fixedly connected to the sleeve 14. The spring 16 is always in a compressed state, so that the spring 16 can ensure that the water baffle 12 is always tightly attached to the inner wall of the water intake tank 11, thereby effectively achieving the blocking of the water inlet 111.
[0035] Please refer to Figure 4A cylindrical protrusion 121 is fixedly provided on the water baffle 12. A separation block 112 is fixedly provided on the inner wall of the water intake tank 11, and one side of the separation block 112 is provided with an inclined surface. When the water baffle 12 is rotated away from the water inlet 111, the protrusion 121 can move along the inclined surface of the separation block 112 until it abuts against the separation block 112, and the separation block 112 can push the water baffle 12 toward the direction close to the rotating shaft 13, so that the water baffle 12 is separated from the water intake tank 11. At this time, the water inlet 111 is fully opened, and the water sample in the water area can smoothly enter the water intake tank 11.
[0036] In addition, please refer to Figure 4 Two blocking blocks 113 are also fixedly mounted on the inner wall of the water intake tank 11. A space is formed between the two blocking blocks 113 to accommodate the protrusion 121. When the protrusion 121 is stuck between the two blocking blocks 113, the water baffle 12 completely blocks the water inlet 111, thereby ensuring that no more water samples will enter the water intake tank 11 after sampling is completed, thereby ensuring the accuracy of sampling. The blocking blocks 113 limit the water baffle 12, making it difficult for the water baffle 12 to rotate, thereby ensuring the firmness of the water baffle 12.
[0037] Please refer to Figure 2 and Figure 3 , the connecting unit 2 connects the adjacent water intake tanks 11 to ensure that the entire sampling device can be operated as a whole. The connecting unit 2 includes a connecting rod 21 and a transmission shaft 22 rotatably arranged in the connecting rod 21. The connecting rod 21 is connected to the water intake tank 11 by a thread. This connection method not only ensures the stability of the structure, but also facilitates rapid assembly and disassembly in actual operation. Among them, a connecting key 23 is fixedly provided at one end of the transmission shaft 22 and the rotating shaft 13, and a keyway matching the connecting key 23 is provided at the other end of the transmission shaft 22 and the rotating shaft 13. When the connecting rod 21 is threadedly connected to the water intake tank 11, the connecting key 23 on the rotating shaft 13 will be inserted into the keyway on the transmission shaft 22, thereby forming a stable transmission structure, ensuring that the power of the drive unit 3 can be smoothly transmitted to the water baffle 12 of each water intake tank 11.
[0038] Please refer to Figure 1 and Figure 2The drive unit 3 is the power source of the entire sampling device, and includes a base 31 and a motor 32 fixedly mounted on the base 31. The base 31 not only provides a stable installation foundation for the motor 32, but is also connected to the connecting rod 21 through its specific structure. Specifically, the connecting rod 21 and the base 31 are connected by threads. A keyway that matches the connecting key 23 is also provided on the output shaft of the motor 32. When the connecting rod 21 is threadedly connected to the base 31, the connecting key 23 on the transmission shaft 22 will be inserted into the keyway on the output shaft of the motor 32, so that when the motor 32 is started, power can be accurately transmitted to each water baffle 12 through the transmission shaft 22 and the rotating shaft 13, driving the water baffle 12 to perform the necessary rotation.
[0039] The implementation principle of the embodiment of the present application is as follows: first, according to the depth of the water area to be sampled, determine and prepare a sufficient number of water intake units 1. Then, these water intake units 1 are tightly connected together through the connecting unit 2 to form a complete sampling device. Finally, the sampling device is placed in the target water area, and the drive unit 3 is started. Driven by the motor 32, its output shaft engages with the connecting key 23 on the transmission shaft 22 through the keyway, driving the transmission shaft 22 to rotate. The transmission shaft 22 is linked to the rotating shaft 13 through the connecting key 23, and the rotating shaft 13 drives the sleeve 14 and the connecting rod 15 to move, and finally drives the water baffle 12 to rotate around the rotating shaft 13. Since the rotating shafts 13 of all water intake boxes 11 are connected to the transmission shaft 22 through the connecting key 23, the power of the motor 32 can be synchronously transmitted to each water baffle 12 to ensure that all water inlet holes 111 are opened and closed at the same time. When protrusion 121 abuts against separation block 112, it slides along the inclined surface, steadily pushing water baffle 12 away from the inner wall of water collection tank 11. Water inlet 111 is fully opened, and water samples from different depths in the water area begin to enter water collection tank 11. As water baffle 12 continues to rotate, when protrusion 121 is stuck between two blocking blocks 113, water inlet 111 is completely blocked, and the sampling process ends. In this way, water samples from different depths of the water area can be obtained simultaneously through a single operation, which not only greatly simplifies the sampling process but also improves the accuracy of the test results.
[0040] The embodiments of this specific implementation method are all preferred embodiments of the present application and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
