[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-5This utility model provides an embodiment of an environmental monitoring multi-point sampling device, including a mounting frame 1; it also includes a rotating knob 21 and a collection assembly. A handle 4 for lifting is fixedly connected to the top of the mounting frame 1. The rotating knob 21 is connected inside the mounting frame 1, and a screw 22 is fixedly connected to the outside of the rotating knob 21. A limit rod 23 is fixedly connected inside the mounting frame 1. An auxiliary fixing device 24 is threadedly connected to the outside of the screw 22. A connecting plate 25 is provided outside the auxiliary fixing device 24. A mounting box 26 is fixedly connected to the bottom of the connecting plate 25. A support rod 210 is fixedly connected inside the mounting box 26. A push plate 28 is slidably connected to the outside of the support rod 210. The push plate 28 is fixedly... A push block 27 is connected to the mounting box 26. A fixing plate 214 is fixedly connected inside the mounting box 26. A spring 215 is fixedly connected to the outside of the fixing plate 214. A limit block 217 is fixedly connected to the outside of the spring 215. An L-shaped slider 218 is fixedly connected to the outside of the limit block 217. A sliding block 29 is slidably connected inside the mounting box 26. A mountain-shaped push block 219 is fixedly connected to the bottom of the sliding block 29. A sliding rod 216 is fixedly connected inside the mounting box 26. A spring 211 is installed on the outside of the support rod 210. A support rod 212 is fixedly connected to the end of the mounting box 26 away from the sliding rod 216. A spring 213 is installed on the outside of the support rod 212. A connecting plate 25 is installed on the inside of the support rod 212. With a collection component, when multi-point sampling is required, pressing the push block 27 causes the push plate 28 to slide outside the support rod 210. Due to the inclined groove inside the sliding block 29, the push plate 28 moves, causing the sliding block 29 to slide upward outside the support rod 212. Under the action of the sliding block 29, the mountain-shaped push block 219 slowly pushes the L-shaped slider 218 to retract from outside the sliding rod 216 into the mounting box 26. This causes the L-shaped slider 218 to bring the spring 215 into the mounting box 26. At this time, another set of connecting plates 25 is inserted outside the mounting box 26. Then, the push block 27 is released, causing the spring 211 to push the push plate 28 to reset. Spring 213 pushes the sliding block 29 to reset the mountain-shaped push block 219. At the same time, spring 3 215 pushes the limiting block 217 into the interior of the connecting plate 25, thereby fixing a set of connecting plates 25 and completing the installation of the device. A sliding groove is provided at the corresponding position of the sliding block 29 and the push plate 28. The push plate 28 is slidably connected to the interior of the sliding block 29. The sliding block 29 is provided to push the L-shaped slider 218 under the push of the push plate 28. A through hole is provided at the corresponding position of the sliding block 29 and the support rod 212. The sliding block 29 is slidably connected to the exterior of the support rod 212. The support rod 212 is provided to limit the sliding direction of the sliding block 29.Through holes are provided at corresponding positions of the mounting box 26 and the limiting block 217. The limiting block 217 is slidably connected inside the mounting box 26. The limiting block 217 facilitates the fixing of the other set of connecting plates 25 in conjunction with the pushing of the spring 215. Through holes are provided at corresponding positions of the connecting plate 25 and the limiting block 217. The limiting block 217 passes through the mounting box 26 and slides inside the connecting plate 25. The connecting plate 25 provides a mounting base for its components. The L-shaped slider 218 and the sliding rod 216... A through hole is provided at the corresponding position of the sliding block 218, which is slidably connected to the outside of the sliding rod 216. The L-shaped slider 218 facilitates the sliding of the limiting block 217 inside the mounting box 26 under the push of the mountain-shaped push block 219. A through hole is provided at the corresponding position of the mounting box 26 and the push block 27, which is slidably connected to the inside of the mounting box 26. The push block 27 facilitates the sliding of the sliding block 29 outside the push plate 28 within the mounting box 26 by pushing the push block 27.

[0023] Please see Figure 5 In this embodiment, the collection component includes a fixing cover 31, which is disposed on the inner side of the connecting plate 25. A sampling bottle 33 is disposed on the inner side of the connecting plate 25 away from the fixing cover 31. A sealing block 32 is fixedly connected to the outside of the fixing cover 31. The sampling bottle 33 is provided to facilitate the collection of samples.

[0024] When multi-point sampling is required during operation, pressing the push block 27 causes the push plate 28 to slide outside the support rod 210. Due to the inclined groove inside the sliding block 29, the push plate 28 moves, causing the sliding block 29 to slide upward outside the support rod 212. Under the action of the sliding block 29, the mountain-shaped push block 219 slowly pushes the L-shaped slider 218 to retract from outside the sliding rod 216 into the mounting box 26. This causes the L-shaped slider 218 to bring the spring 215 into the mounting box 26. At this time, another set of connecting plates 25 is inserted outside the mounting box 26. Then, the push block 27 is released, causing the spring 211 to push the push plate 28 back to its original position. 213 pushes the sliding block 29 to reset the mountain-shaped push block 219. At the same time, spring 3215 pushes the limiting block 217 into the interior of the connecting plate 25, thereby fixing a set of connecting plates 25 and completing the installation of the device. Then, the entire device is placed in water. Since the sealing block 32 outside the fixing cover 31 is connected to the inside of the sampling bottle 33 when it is placed in water, when the device reaches a certain depth, by rotating the rotating torque 21, the rotating torque 21 drives the screw 22 to rotate, thereby causing the auxiliary fixing device 24 to slide outside the limiting rod 23 and move the auxiliary fixing device 24 to both sides. At this time, the sealing block 32 outside the fixing cover 31 is separated from the sampling bottle 33, and the sampling bottle 33 is slowly filled with sample.

[0025] Through the above steps, by pushing the actuating block 27, the pushing plate 28 slides outside the support rod 210. Due to the design of the inclined groove inside the sliding block 29, the movement of the pushing plate 28 will cause the sliding block 29 to slide upward outside the support rod 212. This action will then cause the mountain-shaped pusher 219 to push the L-shaped slider 218 to retract along the sliding rod 216 into the mounting box 26. At the same time, the L-shaped slider 218 will bring the spring 215 into the mounting box 26, inserting another set of connecting plates 25 into the outside of the mounting box 26. After releasing the actuating block 27, the spring 211 pushes the pushing plate 28 to reset, and the spring 213 pushes the sliding block 29 and the mountain-shaped pusher 219 to reset. At the same time, the spring 215 pushes the limiting block 217 into the connecting plate 25, thereby fixing the connecting plate 25, which is conducive to quick assembly of the device and simplifies the operation steps.
