Technical Field
[0001] The utility model relates to the technical field of water sampling, in particular to a water sampling device for water conservancy projects. Background Art
[0002] Water resources are essential for human survival and can be divided into surface water and groundwater resources. Human production and life are inseparable from the existence of water. Currently, water resources are mostly used in rivers, lakes, and reservoirs. Therefore, the protection of surface water resources has become increasingly important. In recent years, with the development of industry, water pollution has also become more serious, bringing serious harm to human life. Environmental monitoring has also been increasing its investment in water resources. Testing water quality is the key to solving the problem of water pollution. Water sampling is one of the important contents of environmental monitoring. Therefore, the use of water sample collectors has become inevitable. When monitoring deep water samples, in order for the water sample collector to overcome buoyancy and enter the water body, it is generally necessary to configure a heavy weight block, which is inconvenient to carry. Therefore, a device is needed that can reduce buoyancy without buoyancy to allow the sampling device to enter the water. Utility Model Content

[0023] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.
[0024] like Figures 1 to 5 As shown, a water sampling device for water conservancy projects includes a water sample collecting tube 1. Slide rails 2 are provided on both sides of the inner wall of the water sample collecting tube 1. The water sample collecting tube 1 is slidably connected to a lifting plate 3 through the slide rails 2. A traction rope 4 is fixedly connected to the top of the water sample collecting tube 1. An expansion rope 5 is fixedly connected to the top of the lifting plate 3. A water inlet 6 is opened at the center of the bottom of the water sample collecting tube 1, and a water outlet 7 is opened on one side of the bottom of the water sample collecting tube 1.
[0025] Example 1: The inner wall shape of the water sample collecting tube 1 is adapted to the inner wall shape of the lifting plate 3, the sliding stroke of the slide rail 2 is equal to the inner wall height of the water sample collecting tube 1, and the lengths of the traction rope 4 and the expansion rope 5 are equal. By arranging a lifting plate 3 that can be raised and lowered inside the water sample collecting tube 1, before entering the water body, the lifting plate 3 is pressed to the bottom of the water sample collecting tube 1, and the buoyancy of the water sample collecting tube 1 in the water is adjusted to the lowest. Equipped with a smaller counterweight block, the sampling device can enter the required water level and reduce the carrying pressure of the counterweight block. After the water sample collecting tube 1 enters the water body, the traction rope 4 is pulled when controlling the lifting of the sampling device. When the corresponding water level is reached, the expansion rope 5 is slowly pulled upwards, and the lifting plate 3 slowly rises under the tension of the expansion rope 5, so that the space between the water sample collecting tube 1 and the lifting plate 3 gradually increases to draw the water sample into it.
[0026] Example 2: The bottom of both sides of the water sample collection tube 1 is fixedly connected with a counterweight block 8. The sum of the gravity of the counterweight block 8 and the water sample collection tube 1 is greater than the sum of the buoyancy received by the two in the water. By arranging the counterweight blocks 8 on both sides of the water sample collection tube 1, the buoyancy of the sampling device can be overcome and the diving speed of the water sample collection tube can be accelerated.
[0027] Example 3: A number of limit blocks 9 are fixedly connected to the outer side of the top of the water inlet 6. The top of the limit block 9 is bent inward, and a closing plate 10 is set inside the limit block 9. The diameter of the closing plate 10 is larger than the diameter of the water inlet 6. By setting the closing plate 10 on the inner side of the water inlet 6, it is normally sealed with the water inlet 6. When the lifting plate 3 rises to increase the internal space of the water sample collection tube 1, the water sample enters the water sample collection tube 1 when the closing plate 10 is pushed open under the action of water pressure. After the sampling is completed, the closing plate 10 closes the water inlet 6 again to store the water sample.
[0028] Example 4: The inner side of the water outlet 7 is located at the bottom of the water sample collection tube 1 , and a valve 11 is provided on the outer side of the water outlet 7 .
[0029] Example 5: An observation window 12 is provided on the front side of the water sample collecting tube 1 . The height of the observation window 12 is equal to that of the water sample collecting tube 1 . The material of the observation window 12 is transparent explosion-proof glass.
[0030] The working principle of this utility model is as follows:
[0031] S1. A lifting plate 3 that can be raised and lowered is set inside the water sample collection tube 1. Before entering the water body, the lifting plate 3 is pressed to the bottom of the water sample collection tube 1, so that the buoyancy of the water sample collection tube 1 in the water is adjusted to the lowest. A smaller counterweight block can be equipped to enable the sampling device to enter the required water level, reducing the carrying pressure of the counterweight block. After the water sample collection tube 1 enters the water body, the traction rope 4 is pulled to control the lifting of the sampling device. When the corresponding water level is reached, the expansion rope 5 is slowly pulled upwards. The lifting plate 3 slowly rises under the tension of the expansion rope 5, so that the space between the water sample collection tube 1 and the lifting plate 3 gradually increases, and the water sample is drawn into it;
[0032] S2. A closing plate 10 is provided on the inner side of the water inlet 6. Under normal circumstances, the closing plate 10 is fitted with the water inlet 6 for sealing. When the lifting plate 3 rises to increase the internal space of the water sample collecting tube 1, the closing plate 10 is pushed open under the action of water pressure, and the water sample enters the water sample collecting tube 1. After the sampling is completed, the closing plate 10 closes the water inlet 6 again to store the water sample.

[0034] 1. The water sampling device for the water conservancy project is provided with a lifting plate 3 that can be raised and lowered inside the water sample collecting tube 1. Before entering the water body, the lifting plate 3 is pressed to the bottom of the water sample collecting tube 1, so that the buoyancy of the water sample collecting tube 1 in the water is adjusted to the lowest. Equipped with a smaller counterweight block, the sampling device can enter the required water level and reduce the carrying pressure of the counterweight block. After the water sample collecting tube 1 enters the water body, the traction rope 4 is pulled when controlling the lifting of the sampling device. When reaching the corresponding water level, the expansion rope 5 is slowly pulled upward, and the lifting plate 3 slowly rises under the tension of the expansion rope 5, so that the space between the water sample collecting tube 1 and the lifting plate 3 is gradually increased to draw the water sample into it.
[0035] 2. The water sampling device used in the water conservancy project has counterweights 8 arranged on both sides of the water sample collecting tube 1 to overcome the buoyancy of the sampling device and speed up the diving speed of the water sample collecting tube.
[0036] 3. The water sampling device used in the water conservancy project is configured by arranging a closing plate 10 on the inner side of the water inlet 6.

After the sampling is completed, the closing plate 10 closes the water inlet 6 again to store the water sample.
