Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0017] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail. This application discloses a sampling device for environmental water body detection. (Refer to...) Figures 1-6 A sampling device for environmental water body detection includes a mobile vehicle 1. A water pump 4 is fixedly connected to the top of the mobile vehicle 1. A drain pipe 5 is fixedly connected to the output end of the water pump 4. A water pumping pipe 6 is fixedly connected to the input end of the water pump 4. A fixed water pipe 7 is provided on one side of the water pumping pipe 6. A sampling water cylinder 16 is fixedly connected to the bottom of the fixed water pipe 7. An anti-blocking mechanism 3 is provided inside the sampling water cylinder 16. The anti-clogging mechanism 3 includes a motor 302, which is fixedly connected to the inner wall of the sampling water cylinder 16. A cam 303 is fixedly connected to the output end of the motor 302. A sliding rod 306 is slidably connected to the inner cavity of the sampling water cylinder 16. A top rod 304 is fixedly connected to the other side of the sliding rod 306. A limit baffle 310 is fixedly connected to the surface of the sliding rod 306. A spring 309 is installed in the inner cavity of the sampling water cylinder 16. A pusher plate 301 is fixedly connected to one side of the sliding rod 306. A filter cleaning brush 307 is fixedly connected to the surface of the sliding rod 306. A filter screen 308 is fixedly connected to the inner wall of the sampling water cylinder 16. A support plate 305 is fixedly connected to the inner wall of the sampling water cylinder 16. The inner wall of the support plate 305 is slidably connected to the surface of the sliding rod 306. The mechanism is installed on a movable... The water pump 4 at the top of the train 1 can pump river water into the sampling water tank 2 through the fixed water pipe 7 to achieve the purpose of sampling. The sampling water tank 16 installed at the bottom of the fixed water pipe 7 can be used to install the anti-clogging mechanism 3. When the water pump 4 pumps river water through the fixed water pipe 7, the anti-clogging mechanism 3 can prevent sand or water plants from clogging the filter screen 308 during operation. The motor 302 installed inside the sampling water tank 16 will drive the cam 303 to rotate. When the protruding part of the cam 303 pushes the push rod 304 to slide, the push plate 301 on one side of the sliding rod 306 pushes out the surrounding water plants. At the same time, the filter cleaning brush 307 pushes out the sand or water plants that are blocked inside the filter screen 308, thereby preventing sand or water plants from clogging the water holes of the filter screen 308.

[0018] Reference Figure 6 The inner cavity of the sampling water tube 16 is fixedly connected to the mounting block 21, and a sealing ring 18 is provided inside the mounting block 21. The sealing ring 18 installed inside the mounting block 21 can effectively isolate the river water and prevent the river water from soaking into the spring 309 and causing it to corrode. Reference Figure 1 and Figure 7 A collar 13 is fixedly connected to the surface of the sampling tube 16. A center ball 14 is fixedly connected to the collar 13 by threads. An underwater camera 15 is fixedly connected to the surface of the sampling tube 16. The collar 13 installed on the surface of the sampling tube 16 can be used to fix the center ball 14 of different sizes and weights according to the water source and water pressure of the diving environment, so as to cope with rivers or lakes of different depths. The underwater camera 15 installed on the surface of the sampling tube 16 allows the user to observe the diving environment of the sampling tube 16 during the diving process and control the diving direction of the sampling tube 16 to prevent collision with rocks in the river. Reference Figure 1 A pull rope 11 is fixedly connected to the surface of the sampling water tube 16, and a position block 12 is fixedly connected to the top of the pull rope 11. When the sampling water tube 16 is placed in the river water, the water pressure of the river water will lift the position block 12. The user can determine the position of the sampling water tube 16 based on the position of the position block 12 for operation. Reference Figure 1 A support platform 8 is fixedly connected to the top of the mobile vehicle 1, and a storage box 9 is fixedly connected to the top of the mobile vehicle 1. The support platform 8 installed on the mobile vehicle 1 supports the fixed water pipe 7 to facilitate user operation and prevents it from contacting the mobile vehicle 1, thus avoiding bending that could affect the pumping speed. The storage box 9 installed on the mobile vehicle 1 can be used to store the sampling water cylinder 16 when the user pushes the mobile vehicle 1, preventing it from falling. Reference Figure 1 and Figure 3 The inner wall of the mobile vehicle 1 is rotatably connected to a rotating block 17, and the top of the rotating block 17 is fixedly connected to a rotating disk 10. The top of the rotating disk 10 is equipped with a sampling water bucket 2. There are six sampling water buckets 2. The rotating block 17 installed inside the mobile vehicle 1 is used to support the rotating disk 10 to rotate on the surface of the mobile vehicle 1. When the drain pipe 5 draws river water, it will be introduced into the sampling water bucket 2. When multiple river water samples need to be drawn, the rotating disk 10 can be rotated to introduce multiple river water samples into the six sampling water buckets 2 respectively, so as to complete the classification and collection of river water samples. Reference Figure 4 A heat-conducting ring 19 is provided on the surface of the push plate 301, and a heat-conducting plate 20 is fixedly connected to one side of the heat-conducting ring 19. When the motor 302 is running, the heat on the surface of the motor 302 will be guided to the heat-conducting plate 20 through the heat-conducting ring 19. At the same time, the river water carries the heat of the heat-conducting plate 20, thus completing the heat dissipation of the motor 302.

[0019] Working principle: First, the sampling tube 16 is placed in the river water. During the descent of the sampling tube 16, the user can observe the descent environment of the sampling tube 16 through the underwater camera 15 via the control device. When there are rocks in the river water, the user can hold the fixed water pipe 7 to adjust the descent position of the sampling tube 16. During the descent, the position block 12 will float on the river surface due to the pressure of the river water. After the sampling tube 16 has finished descending, the water pump 4 starts to work, introducing the river water into the sampling tank 2 through the fixed water pipe 7. While the water pump 4 is running, the motor 302 drives the cam 303 to rotate, and the convex structure of the cam 303 pushes... When the push rod 304 moves the sliding rod 306, the push plate 301 will push away the sand or aquatic plants around the sampling water cylinder 16. When the cam 303 releases the push rod 304, the sliding rod 306 will drive the filter cleaning brush 307 and the push plate 301 to reset under the elastic force of the spring 309. River water enters the sampling water cylinder 16 through the filter holes of the filter screen 308. Depending on the sampling environment, different types of center of gravity balls 14 can be installed to control the diving speed of the sampling water cylinder 16. The position of the sampling water bucket 2 under the drain pipe 5 can be adjusted by rotating the rotating plate 10, which makes it convenient for users to classify and store samples of different river water.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
