DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] In order to make the technical means, creative features, achieving purposes and effects of the utility model easy to understand, the utility model will be further described below in conjunction with specific embodiments.

[0017] Such as Figures 1 - 3As shown in the figure, a water quality detection sampling device for a water purification plant includes a device main body 1.

A clamping head is provided at the top of the device main body 1, and a bottom plate 4 is installed at the lower end of the device main body 1. The connection cover assembly 2 is snap-connected to the device main body 1. A drain pipe 5 is provided at the lower end of the device main body 1, and a handgrip 6 is rotatably connected to the outer wall of the device main body 1.

[0018] Before using the sampling device for sampling, the sampling tube structure 3 and the connection cover assembly 2 are installed and connected together. Subsequently, the end of the sampling tube structure 3 is connected to the conveying pipeline. A valve is provided at the connection part between the conveying pipeline and the sampling tube structure 3. Then, the device main body 1 is carried to the corresponding position through the handgrip 6, and the device main body 1 is placed through the bottom plate 4. At this time, a sealing plug is provided at the end of the drain pipe 5 on the device main body 1. When the device main body 1 is stably placed, the connection cover assembly 2 is clamped to the upper end of the device main body 1 by using the clamping head, so that the device main body 1 is communicated with the conveying pipeline through the sampling tube structure 3. After opening the valve between the conveying pipeline and the sampling tube structure 3, the water in the conveying pipeline flows from the sampling tube structure 3 into the device main body 1, thus realizing the sampling work. When the amount of water flowing into the device main body 1 is sufficient, the valve at the conveying pipeline is closed, and then the connection cover assembly 2 is detached from the upper end of the device main body 1. The device main body 1 is carried to the place for detection experiment through the handgrip 6, the sealing plug on the drain pipe 5 is removed to discharge the sample, and then the water quality of the sample is detected. The next time water quality detection sampling is required, the connection cover assembly 2 can be used again to quickly connect the device main body 1 for sampling. The structure is simple and the use is convenient and fast.

[0019] Through the above embodiments, the connection cover assembly 2 includes a cover body 201 and a connection block 204. The connection block 204 is fixed on the cover body 201, and the cover body 201 is installed at the upper end of the device main body 1. The connection cover assembly 2 further includes a cavity 202, a clamping ring 203, and a threaded hole 205. The cavity 202 is opened on the cover body 201, and the clamping ring 203 is fixed in the cavity 202 on the cover body 201. The clamping head at the upper end of the device main body 1 is inserted between the inner wall of the cover body 201 and the clamping ring 203. The threaded hole 205 is arranged through the cover body 201 and the connection block 204. The sampling tube structure 3 includes a connection hose 301, a first connection head 302, and a second connection head 303. The first connection head 302 and the second connection head 303 are arranged at both ends of the connection hose 301, and the second connection head 303 is connected to the connection cover assembly 2. The sampling tube structure 3 further includes an insertion tube 304 and an external thread 305. The first connection head 302 and the second connection head 303 are respectively fixed at the ends of the connection hose 301. The external thread 305 is arranged on the insertion tube 304, and the insertion tube 304 is fixed on the second connection head 303. The insertion tube 304 is connected to the threaded hole 205 in the connection cover assembly 2 through the external thread 305, and the lower end of the insertion tube 304 is located inside the device main body 1. By providing the connection cover assembly 2 and the sampling tube structure 3, the end of the sampling tube structure 3 is detachably arranged with the connection cover assembly 2, which is convenient for disassembly and replacement. The connection cover assembly 2 and the device main body 1 are connected by a clamping method. When the sampling is completed, it can be quickly disassembled, which is convenient for taking away the device main body 1 with the sample for detection work in the first time. At this time, the connection cover assembly 2 is connected to the conveying pipeline along with the sampling tube structure 3. The next time sampling is required, the connection cover assembly 2 can be directly clamped to the upper end of the device main body 1 for sampling, so that the sampling preparation work does not take a lot of time, saving time and improving the rate in the whole sampling process.

[0020] When assembling the connection cover assembly 2 and the sampling tube structure 3, insert the insertion tube 304 on the second connector 303 into the threaded hole 205, and use the external thread 305 to ensure the fixed connection between the insertion tube 304 and the connection block 204 until the second connector 303 abuts against the connection block 204. After the connection cover assembly 2 and the sampling tube structure 3 are assembled together, use the first connector 302 to connect the connection hose 301 to the valve of the conveying pipeline, and then use the connection cover assembly 2 to connect the device main body 1. During the connection process, directly snap the cover body 201 onto the upper end of the device main body 1, and insert the clamping head into the cavity 202. The clamping head contacts the inner wall of the cover body 201 and the outer wall of the clamping ring 203 respectively, so as to ensure a firm connection effect between the connection cover assembly 2 and the device main body 1. At this time, the lower end of the insertion tube 304 is located inside the device main body 1. After opening the valve at the conveying pipeline, the water in the conveying pipeline enters the insertion tube 304 through the connection hose 301 and finally flows into the device main body 1, thus achieving the purpose of sampling. When the sampling is completed, disassemble the connection cover assembly 2 from the device main body 1, carry the device main body 1, and then perform the detection work on the sample. When needed, the connection cover assembly 2 and the sampling tube structure 3 can be quickly disassembled and replaced. The structure is simple and the operation is highly convenient.
