DETAILED DESCRIPTION

[0022] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0023] Figure 1-Figure 4 An embodiment of the utility model is a water quality sample collection device, comprising a first tank body 1, with fixed plates 2 being axially symmetrically fixedly connected on both sides of the first tank body 1, a square column 3 being arranged on the side of one end of the fixed plate 2, a lowering mechanism 4 for extending the water quality collection length being arranged at the bottom of the square column 3, a hose 5 being wound around the surface of the lowering mechanism 4, and a protective component 6 being fixedly connected to the back side of the square column 3 for preventing swaying during the lowering and collection period.

[0024] The specific problem addressed by this specific embodiment is to solve the problem that during the lowering process, there will be swaying, which will cause the collection position to shift and affect the water quality data. The utility model uses the setting of the protection component 6. During the water quality sample collection, as the lowering mechanism 4 lowers the collection head 7 at one end of the hose 5, it drives the limit rod 64 and the slider 63 on the hose 5 to slide downward inside the slide 62, and is protected by the limit plate 61. In addition, because one end of the limit rod 64 is fixedly connected to the position of one end of the hose 5 near the collection head 7, the swing amplitude of the collection head 7 during the lowering can be reduced, so that the collection head 7 can be accurately lowered to the designated collection position, thereby improving the accuracy of water quality sample collection.

[0025] The protection component 6 includes a limit plate 61 fixedly connected to the back of the square column 3. A slide groove 62 is provided on the surface of the limit plate 61. A slider 63 is slidably connected inside the slide groove 62. A limit rod 64 is fixedly connected to the surface of the slider 63. One end of the limit rod 64 is fixedly connected to the surface of one end of the hose 5. In this specific embodiment, the two sides of the slider 63 are axially symmetrically fixedly connected to the limit column 631. The surface of the limit column 631 is sleeved with a bearing 632. The surface of the bearing 632 is slidably connected to the inner side wall of the slide groove 62. The two sides of the slider 63 are axially symmetrically fixedly connected to the limit column 631. The surface of the limit column 631 is sleeved with a bearing 632. The surface of the bearing 632 is slidably connected to the inner side wall of the slide groove 62. As the slider 63 drives the bearing 632 to slide on the inner side wall of the slide groove 62, the overall sliding efficiency can be improved. When the collection head 7 is lowered to collect water quality samples, the overall smoothness of the lowering is guaranteed, thereby improving the efficiency of water quality sample collection.

[0026] In this specific embodiment, one end of the hose 5 is provided with a collecting head 7 for collecting water sources, the other end of the hose 5 passes through the interior of the first tank body 1 and is connected to a water pump 8, a connecting pipe is provided at the bottom of the water pump 8, the bottom end of the connecting pipe is connected to the second tank body 9, the bottom of the second tank body 9 is provided with a support leg, the bottom of the support leg is provided with a universal wheel for movement, a through hole is opened on the side of the second tank body 9, a drain pipe 10 for taking water is provided inside the through hole, and a stop valve 11 for opening and closing is provided on the surface of the drain pipe 10.
