DETAILED DESCRIPTION

[0023] 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.

[0024] like Figure 1-Figure 5 As shown, the environmental monitoring sampling device provided in this embodiment includes two symmetrically arranged support frames 1, and the two support frames 1 are both slidably provided with driving mechanisms 2, and a sampling mechanism 3 is connected between the two driving mechanisms 2. A slide groove 15 is vertically opened in the support frame 1, and the driving mechanism 2 includes a slider 16 and a driving motor 17 arranged inside the slider 16. An electric slide rail 18 for driving the slider 16 to slide is arranged inside the slide groove 15. When sampling, the angle of the sampling tube 301 is adjusted by using the driving motor 17, and then the sampling tube 301 is driven down by the electric slide rail 18 until it is inserted into the ground or water surface, and then the sampling tube 301 is driven to rotate to a state with the opening facing upward by using the driving motor 17. During the adjustment process, the electric slide rail 18 will simultaneously drive the sampling tube 301 to move upward;

[0025] The sampling mechanism 3 includes a sampling tube 301, a first flushing mechanism 302 arranged above the sampling tube 301, and a second flushing mechanism 303 arranged on the outer surface of the sampling tube 301, wherein connecting rods 19 for connecting to the output end of the driving motor 17 are arranged on both sides of the sampling tube 301, and the opening at the lower end surface of the sampling tube 301 is an inclined opening, and the inclined opening is arranged to facilitate the sampling tube 301 to be inserted into the ground and to facilitate sampling. The lower end surface of the support frame 1 is provided with moving wheels, and the moving wheels can realize the movement of the equipment;

[0026] The first flushing mechanism 302 penetrates to the rear end of the sampling tube 301, and includes a mounting frame 6 connected to the rear end of the sampling tube 301 through a threaded rod 5, a sealing block 7 fixedly connected to the center of the mounting frame 6, a plurality of high-pressure nozzles 8 distributed on the sealing block 7 and penetrating into the interior of the sampling tube 301, and a water cavity 9 for supplying water to the high-pressure nozzles 8, and the water cavity 9 is connected to the high-pressure water pump 402 through a first connecting hose 10;

[0027] One end surface of the sealing block 7 inside the sampling tube 301 is provided with a truncated cone groove 11 corresponding to the number of high-pressure nozzles 8. The water outlet of the high-pressure nozzle 8 is inside the truncated cone groove 11. The truncated cone groove 11 is used to diffuse the high-pressure water source sprayed by the high-pressure nozzle 8. When the sampling tube 301 needs to be cleaned, the water source inside the water tank 401 is transported to the water cavity 9 through the first connecting hose 10 by the high-pressure water pump 402, and then diffused and sprayed by the high-pressure nozzle 8, so as to realize the cleaning of the inner wall of the sampling tube 301. It should be noted that when the sampling tube 301 is flushed, the sampling tube 301 is in a state of opening downward;

[0028] The second flushing mechanism 303 is connected to the first flushing mechanism 302. The second flushing mechanism 303 includes a cavity collar 12 fixedly sleeved on the surface of the sampling tube 301 and a plurality of water spray pipes 13 connected to the lower end surface of the cavity collar 12. The plurality of water spray pipes 13 surround the surface of the sampling tube 301. The drainage end of the water spray pipe 13 is close to the surface of the sampling tube 301. The cavity collar 12 is connected to the water cavity 9 through the second connecting hose 14. When the first flushing mechanism 302 flushes the inner wall of the sampling tube 301, part of the water source is transported to the inside of the cavity collar 12 through the second connecting hose 14, and then sprayed out through the plurality of water spray pipes 13, thereby achieving the cleaning of the outer wall of the sampling tube 301.

[0029] A water supply mechanism 4 connected to the first flushing mechanism 302 is supported by two support frames 1 . The water supply mechanism 4 includes a water tank 401 with a water delivery port and a high-pressure water pump 402 arranged inside the water tank 401 .

[0030] like Figure 1-Figure 5As shown, the principle of the environmental monitoring sampling device provided in this embodiment is as follows: when in use, the driving mechanism 2 is used to drive the sampling tube 301 to rotate to a state with the opening facing downward, and the driving mechanism 2 and the sampling tube 301 are driven downward by the electric slide rail 18 to be directly inserted into the ground or water surface, and then the driving mechanism 2 is used to drive the sampling tube 301 to rotate to a state with the opening facing upward, and the electric slide rail 18 is also used to drive the sampling tube 301 to move upward. After the detection is completed, the driving mechanism 2 is used to drive the sampling tube 301 to rotate to a state with the opening facing downward, and at the same time, the water supply mechanism 4 is used to supply water to the first flushing mechanism 302 and the second flushing mechanism 303, thereby realizing the synchronous pouring of the sampling tube 301 and the cleaning of the inner and outer walls, which greatly reduces the time for flushing the sampling tube and greatly improves the detection efficiency.

[0031] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve technical problems within a certain error range and basically achieve technical effects.

[0032] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a product or system including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such product or system. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the product or system including the elements.

[0033] The above description shows and describes several preferred embodiments of the utility model, but as mentioned above, it should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the utility model concept described herein through the above teachings or the technology or knowledge of the relevant field.
