[0004] While the patented technology can block garbage from entering rivers, the sampling equipment sinks to the bottom of the riverbed and sucks up the silt, thus affecting the quality of the river samples. Utility Model Content
[0005] In view of the problems of existing sampling equipment where the sampling head sinks to the bottom of the riverbed to absorb water, resulting in the absorption of sediment along with the water, and the inability to sample water from different water layers, this utility model is proposed.
[0006] Therefore, the purpose of this utility model is to provide a water quality sampler for river pollution monitoring, which aims to: sample different water layers without inhaling sediment or garbage during the sampling process.
[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a river pollution monitoring water quality sampler, including a sampler, wherein a sampling mechanism is fixedly installed on the inner surface of the sampler;
[0008] The sampling mechanism includes an automatic closing assembly, which includes a sampling box.

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0025] Example 1
[0026] Reference Figures 1-5 This is the first embodiment of the present invention, which provides a river pollution monitoring water quality sampler. The river pollution monitoring water quality sampler includes a sampler 1, and a sampling mechanism 2 is fixedly installed on the inner surface of the sampler 1.
[0027] The sampling mechanism 2 includes an automatic closing assembly 21, which includes a sampling box 211. A rotating rod 212 is rotatably mounted on the inner surface of the sampling box 211. A closing plate 213 is fixedly mounted on the outer surface of the rotating rod 212. A torsion spring 214 is provided on the outer surface of the rotating rod 212 away from the closing plate 213. The top end of the torsion spring 214 is fixedly connected to the inner wall of the sampling box 211. A limit block 215 is fixedly mounted on the inner surface of the sampling box 211.
[0028] The sampling mechanism 2 also includes a first water pump 216. The bottom of the first water pump 216 is fixedly connected to the inner wall of the sampler 1. The input end of the first water pump 216 is connected to a suction pipe 217. The left end of the suction pipe 217 passes through the sampler 1 and extends to the outside of the sampler 1. The bottom end of the suction pipe 217 is connected to the top of the sampling box 211.
[0029] The sampling mechanism 2 also includes a detection component 23, which includes a sensing rod 231. The top end of the sensing rod 231 is fixedly connected to the bottom of the float 221. A touch sensor 232 is fixedly installed on the inner surface of the sensing rod 231, and a slide rod 233 is slidably installed on the inner surface of the sensing rod 231.
[0030] During use, water is drawn from the sampling box 211 by the No. 1 water pump 216 and the suction pipe 217. When the sampling box 211 is drawing water, the air pressure or water flow will drive the closing plate 213 to rotate, so that the water layer is drawn into the sampling box 211 and then drawn out of the outside of the sampling machine 1 through the suction pipe 217. When it is not necessary for the sampling box 211 to take samples, the torsion spring 214 drives the rotating rod 212 to rotate through the closing plate 213, closing the sampling box 211, so that the mud and sand garbage outside will not be drawn into it. When the sampling box 211 sinks into the riverbed, the sliding rod 233 moves in the sensing rod 231 and triggers the touch sensor 232, so that the equipment senses that the sampling box 211 has reached the bottom, and then draws out some of the water in the water bag 222 to reduce its counterweight.
[0031] Example 2
[0032] Reference Figures 2-4 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the sampling mechanism 2 further includes a depth control component 22, which includes a float 221, and a water bladder 222 is fixedly installed on the inner surface of the float 221.
[0033] The depth control component 22 also includes a second water pump 223. The output end of the second water pump 223 is connected to a water outlet pipe 224. The top end of the water outlet pipe 224 is connected to a valve 225. A dispensing pipe 226 is fixedly installed on the left side of the valve 225. A diversion pipe 227 is fixedly installed on the inner surface of the dispensing pipe 226.
[0034] The inner surface of valve 225 is fixedly connected to the outer surface of suction pipe 217, and the bottom end of diversion pipe 227 is connected to the top of water bag 222.
[0035] Valve 225 controls the opening and closing of multiple diversion pipes 227 to control the amount of water injected into the water bladder 222, thereby controlling the counterweight of the float 221.
[0036] During use, water is pumped from outlet pipe 224 into diversion pipe 227 by second water pump 223. Valve 225 controls the opening and closing of each diversion pipe 227, so that the water in the diversion pipe 227 is injected into the corresponding water bladder 222, which increases the gravity of the float 221 and makes it sink. By controlling the water content in the water bladder 222, the sampling box 211 can be controlled to stay in different water layers.
[0037] The remaining structure is the same as that in Example 1.
[0038] Based on embodiments 1-5, the working principle of this utility model is as follows: The user first throws the float 221 carrying the sampling box 211 into the water. Then, water is pumped from the outlet pipe 224 into the diversion pipe 227 by the second water pump 223. Valve 225 controls the opening and closing of each diversion pipe 227, causing water in the diversion pipe 227 to flow into the corresponding water bladder 222, increasing the weight of the float 221 and causing it to sink. By controlling the water content in the water bladder 222, the sampling box 211 is controlled to remain at different water levels. Then, the water in the sampling box 211 is sucked out by the first water pump 216 and the suction pipe 217. When water is being drawn in, air pressure or water flow will cause the closing plate 213 to rotate, so that the water in that layer is drawn into the sampling box 211 and then drawn out of the outside of the sampler 1 through the suction pipe 217. When it is not necessary for the sampling box 211 to take a sample, the torsion spring 214 drives the rotating rod 212 to rotate through the closing plate 213, closing the sampling box 211, so that the mud and sand outside will not be drawn into it. When the sampling box 211 sinks into the riverbed, the sliding rod 233 moves in the sensing rod 231 and triggers the touch sensor 232, so that the device senses that the sampling box 211 has reached the bottom, and then draws out some of the water in the water bag 222 to reduce its counterweight.
[0039] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
