Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Reference Figure 1 、 Figure 3 and Figure 5The utility model provides an embodiment: a water sample collection device for environmental quality detection, including a bracket 1, which is convenient for installing the roller 3 and the handrail 2 by setting the bracket 1. A sampling pump 14 is fixedly connected to the left side of the upper part of the bracket 1, and the output end of the sampling pump 14 is fixedly connected to one end of the delivery pipe 15.

A filter plate 18 is installed at the lower part of the sampling head 17. When sampling, by starting the sampling pump 14, water is sucked in through the sampling head 17, and then impurities in the water are removed through the filter plate 18. Filter, then, through the cooperation of the hose 16 and the delivery pipe 15, the water is transported to the inside of the collection bottle 21, and installation cavities 22 are provided on both sides of the interior of the sampling head 17. A replacement component 23 is provided inside the installation cavity 22, and the replacement component 23 is used to replace the filter plate 18. The left side of the outside of the bracket 1 is fixedly connected to the installation frame 4, the lower part of the installation frame 4 is fixedly connected to the installation plate 5, and the upper two sides of the installation plate 5 are fixedly connected to the fixing blocks 8. The outside of the left fixing block 8 is provided with a motor 7, and the output end of the motor 7 is fixedly connected to a rotating rod 9, which is rotatably connected to the inside of the two fixing blocks 8. The rotating rod 9 is fixedly connected to the outside of the gear 10, and the mounting plate 5 is provided inside. A rack plate 11 is provided, and the gear 10 is meshed with the rack plate 11. The gear 10 and the rack plate 11 are made of stainless steel. Stainless steel has strong corrosion resistance, especially in a humid, rainy or corrosive environment, which can effectively avoid rust or corrosion problems and extend the service life of the gear 10 and the rack plate 11. The outside of the rack plate 11 is fixedly connected to a guide block 12, and the bottom of the rack plate 11 is fixedly connected to a mounting rod 19. The bottom of the mounting rod 19 is fixedly connected to the outside of the sampling head 17. The outside of the mounting plate 5 is fixedly connected to a mounting ring 6, and the motor 7 is fixedly connected to the inside of the mounting ring 6. By setting the mounting ring 6, it is convenient to fix the motor 7. The mounting plate 5 and the middle of the mounting frame 4 are fixedly connected with a guide rod 13, and the guide block 12 is slidably connected to the outside of the guide rod 13. The guide rod 13 is provided to guide the guide block 12. A first through hole 20 is provided inside the mounting plate 5, and the rack plate 11 is slidably connected to the inside of the first through hole 20. The first through hole 20 is provided to facilitate the movement of the rack plate 11. A collecting bottle 21 is provided in the middle of the bracket 1. The collection bottle 21 is provided to facilitate the collection of the collected water samples. Rollers 3 are installed all around the lower part of the bracket 1. The rollers 3 are provided to facilitate the movement of the device. An armrest 2 is fixedly connected to the right side of the upper part of the bracket 1. The armrest 2 is provided to facilitate the use of the operator.

[0028] Specifically, when sampling the water body, first, through the cooperation of the armrest 2 and the roller 3, the operator can easily move the entire bracket 1 to the sampling position. After reaching the sampling position, the operator starts the sampling pump 14 by immersing the sampling head 17 in the water body. The function of the sampling pump 14 is to suck the water sample in the water body through the sampling head 17, thereby completing the water sample collection process. In this process, the water sample will pass through the filter plate 18 installed at the bottom of the sampling head 17. The filter plate 18 is used to preliminarily filter out impurities, suspended particles or other large-volume solid matter in the water. The water sample that passes through the filter plate 18 is transported through the hose 16. Subsequently, the water sample will be transported to the inside of the collection bottle 21 through the delivery pipe 15. The collection bottle 21 serves as a storage container for water samples, ensuring that the collected water samples are not contaminated by the outside world during transportation and storage, and maintaining their original state, which is convenient for subsequent laboratory testing. When the sampling depth needs to be adjusted, the operator starts the motor 7, and the motor 7 drives the output end solid The fixed rotating rod 9 rotates, and the rotating rod 9 is located inside the two fixed blocks 8. When rotating, it drives the external fixed gear 10 to rotate synchronously. The gear 10 is engaged with the rack plate 11. Through the rotation of the gear 10, the rack plate 11 moves downward or upward. During the movement of the rack plate 11, the mounting rod 19 installed at its lower part also moves accordingly. The movement of the mounting rod 19 directly drives the sampling head 17 fixed at the bottom to move up and down. In this way, the sampling head 17 can be accurately adjusted to the required water layer depth. Whether it is surface, middle or bottom water samples, they can be flexibly collected, which improves the flexibility and accuracy of water sample collection, so that the sampling process is not limited to the surface water layer, thereby obtaining more comprehensive water quality data. Through this depth-adjustable sampling device, water samples from each water layer can be effectively collected to ensure that the test results can cover all levels of the water body. This multi-level sampling method significantly improves the accuracy of water sample detection and can better reflect the true water quality of the water body.

[0029] Reference Figure 2 、 Figure 4 and Figure 6The replacement component 23 includes a fixed rod 2301, which is fixedly connected to the inside of the installation cavity 22. The fixed rod 2301 is slidably connected to the outside of the fixed rod 2301 with a slider 2302. The upper part of the slider 2302 is fixedly connected to a moving rod 2304. The moving rod 2304 is used to move the slider 2302. The moving rod 2304 is slidably connected to the inside of the sampling head 17. The fixed rod 2301 is provided with a spring 2303 on the outside. The spring 2303 is made of stainless steel. The stainless steel can form a protective oxide film in water to prevent moisture. , oxygen and other corrosive substances on the metal, can maintain its elasticity and performance, not easy to deform or fail, the slider 2302 is fixedly connected to the lower part of the rod 2305, the rod 2305 is used to limit the filter plate 18, the sampling head 17 is provided with a second through hole 24, the rod 2305 is slidably connected to the inside of the second through hole 24, the second through hole 24 is provided to facilitate the movement of the rod 2305, the filter plate 18 is provided with a socket 25, the rod 2305 is plugged into the socket 25, which improves the stability of the installation of the filter plate 18.

[0030] Specifically, when the filter plate 18 needs to be replaced, first, the operator pulls the moving rod 2304, and the force transmitted by the moving rod 2304 drives the external fixed slider 2302 to move smoothly along the outside of the fixed rod 2301. In this process, the slider 2302 moves and drives the lower fixed plug rod 2305 to move together. At the same time, the movement of the plug rod 2305 generates pressure on the spring 2303 set on the outside of the fixed rod 2301, gradually compressing the spring 2303, causing the spring 2303 to deform. This process puts the spring 2303 into a stressed state and shrinks it. When the plug rod 2305 is completely out of the inside of the socket 25, the spring 2303 is still in a compressed state, and the plug rod 2305 and the socket 2301 are in a compressed state. 5 is no longer directly connected. At this time, the operator can easily remove the filter plate 18 from the lower part of the sampling head 17 for replacement or maintenance. When replacing a new filter plate 18, the operator only needs to insert the new or cleaned filter plate 18 into the lower part of the sampling head 17. Then, the operator releases the moving rod 2304. At this time, the spring 2303 will use its elasticity to restore its original shape. Under the reaction force of the spring 2303, the insertion rod 2305 will automatically rebound and insert into the inside of the socket 25, thereby completing the fixation of the filter plate 18. The operator can quickly clean or replace the blocked or contaminated filter plate 18 to ensure the normal operation of the equipment. The replacement process is simple and efficient, which greatly reduces maintenance time and improves the continuity of sampling work.

[0031] Working principle: When sampling water, first, the bracket 1 is moved to the sampling position with the cooperation of the handrail 2 and the roller 3, and then, the sampling head 17 is immersed in the water, the sampling pump 14 is started, and water is sucked in through the sampling head 17, and then the impurities in the water are filtered through the filter plate 18, and then it is transported through the hose 16. Finally, the sampled water is transported to the inside of the collection bottle 21 through the delivery pipe 15. When it is necessary to adjust the sampling depth, the motor 7 is started, and the motor 7 drives the rotating rod 9 fixed at the output end to rotate inside the two fixed blocks 8. When the rotating rod 9 rotates, the externally fixed gear 10 rotates, and the gear 10 rotates and drives the externally meshed rack plate 11 downward, and when the rack plate 11 moves downward, it drives the lower fixed mounting rod 19 to move, and the mounting rod 19 moves and drives the bottom fixed sampling head 17 to move, thereby realizing the water sampling device, which is convenient for adjusting the depth of water sample collection, and can collect water from multiple water layers such as the surface, middle and bottom layers. The water sample is collected to more comprehensively reflect the water quality of the entire water body and improve the accuracy of water sample detection. When the filter plate 18 needs to be replaced, first, the movable rod 2304 is pulled to move the external fixed slider 2302 outside the fixed rod 2301. When the slider 2302 moves, the lower fixed plug rod 2305 is moved and the spring 2303 provided on the external sleeve of the fixed rod 2301 is squeezed, so that the spring 2303 is deformed under the force. When the plug rod 2305 is separated from the socket 25, the filter plate 18 can be taken out from the lower part of the sampling head 17 for replacement. During installation, the filter plate 18 is snapped into the lower part of the sampling head 17. Then, the moving rod 2304 is released and the insertion rod 2305 is inserted into the interior of the insertion hole 25 under the reaction force of the spring 2303. This makes it easy to disassemble and replace the filter plate 18 installed at the lower part of the sampling head 17, and to clean the filter plate 18, thereby avoiding the influence of blockage on the sampling efficiency and quality, and improving the sampling efficiency.
