[0011] Preferably, the bottom end of the floating plate is provided with a waterproof rubber pad.
[0012] The beneficial effects of this utility model are as follows:
[0013] 1. The sample collection device of this utility model allows the float plate to float on the water surface through a float bottle at the bottom of the float plate. The first, second, and third water inlet pipes are connected by a fixing component. Because the water inlet pipes need to be interconnected, when the interconnected water storage pipes are placed into the water inlet pipes, the connection points of the water inlet pipes and the water storage pipes are designed to fit tightly. The tight fit is designed to prevent water from different levels of water flow from entering other water inlet pipes when the water inlet pipes are placed in the river, thus preventing water flow from entering the water inlet pipes before water collection begins. Therefore, a water-blocking ring is used. When the first water inlet pipe is inserted into the water source to be sampled, the water flow cannot enter the water inlet pipe from the filter tank. Then the water-blocking ring is opened, and water can be pumped out through the pumping component. The water inlet grooves opened on the connected first, second, and third water inlet pipes are at different levels. Through the pumping component, water from different levels of water source can be directly pumped into the first, second, and third water storage pipes.
[0014] 2. In the sample collection device of this utility model, after water flows into the first, second, and third inlet pipes, the water flow cannot enter the first, second, and third water storage pipes because of the pressure block at the inlet of the pressure block. At this time, the staff needs to pull the connecting rod to move the pressure block upward, and the water flow is drawn into the first, second, and third water storage pipes by the pulling force to complete the water collection. Then, the staff moves the T-shaped plate outward, and the first, second, and third inlet pipes will move upward due to the connecting plate, so that the water-blocking ring returns to the position of the filter tank and the water inlet tank, blocking the inlet positions of the first, second, and third water storage pipes in sequence, preventing the collected water from flowing out of the first, second, and third water storage pipes.

Detailed Implementation
[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0025] like Figures 1 to 7As shown in the embodiment of this utility model, a sample collection device includes a float plate 1; a pair of first through grooves 2 are provided on the float plate 1; a cylinder 4 is slidably connected inside the float plate 1; a connecting plate 5 is provided at the bottom end of the float plate 1; a first water inlet pipe 6 is fixedly connected to the bottom end of the connecting plate 5; a second water inlet pipe 7 and a third water inlet pipe 8 are provided at the bottom end of the first water inlet pipe 6; a filter groove 9 is provided on the first water inlet pipe 6, the second water inlet pipe 7, and the third water inlet pipe 8; a first water storage pipe 10 is provided inside the first water inlet pipe 6; the first water inlet pipe 6 is provided with a first water storage pipe 10; the second water inlet pipe 7 and the third water storage pipe 8 are provided with a filter groove 9; a first water storage pipe 10 is provided inside the first water inlet pipe 6; the first water inlet pipe 7 and the third water storage pipe 8 are provided with a filter groove 9 ... The second water inlet pipe 7 is equipped with a second water storage pipe 11; the third water inlet pipe 8 is equipped with a third water storage pipe 12; each of the water storage pipes has an inlet 13 on its outer circular wall; the first water storage pipe 10, the second water storage pipe 11, and the third water storage pipe 12 are fixedly connected to each other; the first water inlet pipe 6, the second water inlet pipe 7, and the third water inlet pipe 8 are connected by a fixing component; each of the first water inlet pipe 6, the second water inlet pipe 7, and the third water inlet pipe 8 is equipped with a water-blocking component; and each of the first water storage pipe 10, the second water storage pipe 11, and the third water storage pipe 12 is equipped with a water pumping component. A pair of float bottles 15 are fixed to the bottom end of the float plate 1. During operation, the float plate 1 floats on the water surface through the float bottles 15 at the bottom end. The first water inlet pipe 6, the second water inlet pipe 7, and the third water inlet pipe 8 are connected by fasteners. Because the water inlet pipes need to be interconnected, when the interconnected water storage pipes are placed into the water inlet pipes, the connection points of the water inlet pipes and the water storage pipes are designed to fit tightly. This tight fit is designed to prevent water from different levels from entering other water inlet pipes when the water inlet pipes are placed in the river, thus preventing... Before water collection even begins, water flows into the inlet pipe. Therefore, the water-blocking ring 14 prevents water from entering the inlet pipe from the filter tank 9 when the inlet pipe of the first assembly is inserted into the water source to be sampled. Then, the water-blocking ring 14 is opened, and water can be pumped through the pumping device. The inlet tanks on the connected first inlet pipe 6, second inlet pipe 7, and third inlet pipe 8 are at different levels. Through the pumping device, water from different levels can be directly pumped into the first storage pipe 10, second storage pipe 11, and third storage pipe 12.
[0026] The fastener includes a set of connecting rings 16; the set of connecting rings 16 are respectively fixed to the outer circular wall of the bottom end of the first water inlet pipe 6, the two ends of the second water inlet pipe 7, and the top end of the third water inlet pipe 8; the connecting rings 16 on the outer circular wall of the bottom end of the first water inlet pipe 6 and the connecting rings 16 on the outer circular wall of the top end of the second water inlet pipe 7 are connected by a pair of first bolts 17; the connecting rings 16 on the outer circular wall of the bottom end of the second water inlet pipe 7 and the connecting rings 16 on the outer circular wall of the top end of the third water inlet pipe 8 are connected by a pair of second bolts 18. In operation, the connecting rings 16 are fixed in sequence, and the first water inlet pipe 6 and the second water inlet pipe 7 are connected by the first bolts 17 to make them firm. The connecting rings 16 at the bottom end of the second water inlet pipe 7 and the connecting rings 16 on the outer circular wall of the top end of the third water inlet pipe 8 are connected by a second thread to form a long water inlet pipe that can be divided into different layers.
[0027] A pair of T-shaped plates 19 are slidably connected in each of the first through slots 2; a pair of T-shaped plates 19 have a first groove 20 at their bottom ends; a pair of second grooves 21 are provided on the outer circular wall of the connecting plate 5; a connecting plate 24 is rotatably connected in each of the first grooves 20; a first connecting post 23 is fixedly connected in each of the second grooves 21; the other side of each pair of connecting plates 24 is rotatably connected to the first connecting post 23. During operation, when the T-shaped plates 19 are manually pushed to slide inward in the first through slots 2 on the float plate 1, the connecting plate 5 moves downward due to the connecting plate 24, and the distance it moves is the distance of the first through slot 2.
[0028] The water-blocking component includes a pair of connecting rods 25; the top ends of the pair of connecting rods 25 are fixed to the bottom end of the cylinder 4, and the bottom ends of the connecting rods 25 pass through the first water inlet pipe 6, the second water inlet pipe 7, and the third water inlet pipe 8, and are slidably connected inside the first water inlet pipe 6, the second water inlet pipe 7, and the third water inlet pipe 8; a set of water-blocking rings 14 are fixedly connected to the pair of connecting rods 25; the set of water-blocking rings 14 are respectively slidably connected to the outer circular wall of the first water storage pipe 10, the second water storage pipe 11, and the third water storage pipe 12. During operation, by setting the water-blocking rings 14 in the first water storage pipe 10, the second water storage pipe 11, and the third water storage pipe 12... On the outer circular wall, when the workers put the assembled first inlet pipe 6, second inlet pipe 7, and third inlet pipe 8 into the river, the water-blocking ring 14 separates the filter tank 9 and the inlet 13, preventing water from entering the inlet 13 from the filter tank 9. After the first inlet pipe 6, second inlet pipe 7, and third inlet pipe 8 are in place, when the T-shaped plate 19 is moved inward from above, the assembled first inlet pipe 6, second inlet pipe 7, and third inlet pipe 8 will move downward a short distance. In this way, the water-blocking ring 14 will leave the filter tank 9 and the inlet tank, and the water will flow into the inlet pipe.
[0029] The pumping component includes a pull rod 27; one end of the pull rod 27 passes through the cylinder 4 and is slidably connected inside the cylinder 4; pressure blocks 26 are provided in the first water storage pipe 10, the second water storage pipe 11, and the third water storage pipe 12; the other end of the pull rod 27 passes through the first water storage pipe and the internal pressure block 26, and also passes through the second water storage pipe 11 and the internal pressure block, and is fixed to the top of the pressure block 26 inside the third water storage pipe 12. During operation, water flows into the first water inlet pipe 6, the second water inlet pipe 7, and the third water inlet pipe 8, but because the pressure block 26 is located at the water inlet of the first water storage pipe 10, the second water storage pipe 11, and the third water storage pipe 12, the water flow cannot enter the first water storage pipe 10. Inside the second and third water storage pipes 11 and 12, the staff needs to pull the connecting rod 25 to move the pressure block 26 upward, drawing water into the first, second, and third water storage pipes 10 and 12 through the pulling force, thus completing the water extraction. Then, the staff moves the T-shaped plate 19 outward, causing the first, second, and third water inlet pipes 6, 7, and 8 to move upward due to the connecting plate 24, allowing the water-blocking ring 14 to return to the positions of the filter tank 9 and the water inlet tank, thereby blocking the inlet 13 positions of the first, second, and third water storage pipes 10 and 11 and 12 in sequence, preventing the extracted water from flowing out of the first, second, and third water storage pipes 10 and 12.
[0030] The bottom of the float 1 is equipped with a water-repellent rubber pad. During operation, when the float 1 is placed on the river and floats on the water surface via the float bottle 15, the water surface may be unstable and water may slosh to the bottom of the float 1. The waterproof rubber pad can be used to prevent water from getting out of the water.
[0031] Working principle: The float plate 1 floats on the water surface via the float bottle 15 at its bottom. The first, second, and third inlet pipes 6, 7, and 8 are connected via fixing components. Since the inlet pipes need to be interconnected, when the interconnected storage pipes are placed into the inlet pipes, the connection points are designed to fit tightly. This tight fit prevents water from different levels of flow from entering other inlet pipes before water collection begins. Therefore, a water-blocking ring 14 is used. When the first inlet pipe is inserted into the water source to be sampled, water cannot flow from the filter tank 9 into the inlet pipe. Then, the water-blocking ring 14 is opened, and water can be pumped out using the pumping component. The water inlet troughs on the first, second, and third water inlet pipes 6, 7, and 8 represent different water levels. Using a pump, water from these different levels can be directly drawn into the first, second, and third water storage pipes 10, 11, and 12. Connecting rings 16 are sequentially secured, and the first and second water inlet pipes 6 and 7 are connected firmly using the first bolt 17. The connecting rings 16 at the bottom of the second water inlet pipe 7 and the connecting rings 16 on the outer wall of the top of the third water inlet pipe 8 are connected by a second thread, forming a long, layered water inlet pipe. A connecting plate 24 is rotatably connected within the first groove 20 at the bottom of the T-shaped plate 19. The connecting plate 24 connects the T-shaped plate 19 to the connecting disc 5. The T-shaped plate 19 is manually pushed... When plate 19 slides inward in the first through groove 2 on float plate 1, connecting plate 5 moves downward due to connecting plate 24, the distance of which is the distance of the first through groove 2. By setting water-proof ring 14 on the outer circular wall of first water storage pipe 10, second water storage pipe 11, and third water storage pipe 12, when the workers put the assembled first water inlet pipe 6, second water inlet pipe 7, and third water inlet pipe 8 into the river, water-proof ring 14 separates filter tank 9 and inlet 13, preventing water flow from filter tank 9 into inlet 13. After the first water inlet pipe 6, second water inlet pipe 7, and third water inlet pipe 8 are in place, when the T-shaped plate 19 is moved inward from above, the assembled first water inlet pipe 6, second water inlet pipe 7, and third water inlet pipe 8 will move downward a short distance. When the water-isolating ring 14 separates from the filter tank 9 and the inlet tank, water flows into the inlet pipe. After entering the first inlet pipe 6, the second inlet pipe 7, and the third inlet pipe 8, the water cannot enter the first, second, and third water storage pipes 10 and 12 due to the pressure block 26 at its inlet point. At this point, the operator needs to pull the connecting rod 25 to move the pressure block 26 upwards, drawing the water into the first, second, and third water storage pipes 10 and 11 through the pulling force. Then, by moving the T-shaped plate 19 outwards, the first, second, and third inlet pipes 6, 7, and 8 will move upwards due to the connecting plate 24.Return the water-sealing ring 14 to the positions of the filter tank 9 and the inlet tank, and sequentially block the inlet 13 positions of the first water storage pipe 10, the second water storage pipe 11, and the third water storage pipe 12 to prevent the collected water from flowing out of the first water storage pipe 10, the second water storage pipe 11, and the third water storage pipe 12. When the float 1 is placed on the river and floats on the water surface via the float bottle 15, because the water surface may be uneven and water may slosh to the bottom of the float 1, a waterproof rubber pad can be used to prevent water from flowing out.
