DETAILED DESCRIPTION

[0030] In order to make the technical means, creative features, purposes and effects achieved by the utility model easy to understand, the utility model is further described below in combination with specific embodiments.

[0031] For example, Figure 1 And Figure 2As shown, a sewage sampling cylinder for water conservancy detection, including outer tube 1, outer tube 1 outer surface left upper side fixedly connected with pull rod 6, outer tube 1 outer surface lower part fixedly connected with scraping device 2, outer tube 1 lower end fixedly connected with water inlet device 3, outer tube 1 inner cavity is installed with sampling storage device 5, sampling storage device 5 lower part fixedly connected with conical column 4.

[0032] The device needs to be moved to the required sampling sewage by the pull rod 6 before implementation.

[0033] In the above, the device is placed in the sampled sewage by the pull rod 6, and when the desired depth is reached, the water inlet device 3 is pulled to open the water inlet device 3. The water will enter the sampling storage device 5. After the sampling storage device 5 is filled, the water inlet device 3 is closed, so that the device is taken out of the water without allowing other areas of the sewage to enter the sampling storage device 5. After the device is taken out, the sampling storage device 5 is removed from the device, and the sampled water is poured out for detection.

[0034] In the above, the conical column 4 can make the resistance of the device entering the water smaller, so that the device can better perform in the water.

[0035] In the above, the water inlet device 3 can filter impurities in the water, such as water grass, garbage, etc., so that they do not enter the sampling storage device 5 and affect the detection results.

[0036] In the above, if the impurities in the water adhere to the water inlet device 3, the scraping device 2 can be rotated to scrape the impurities adhering to the water inlet device 3.

[0037] Further, in order to achieve the purpose of filtering impurities in the water by the water inlet device 3 and allowing the device to reach the required sampling depth and enter the water into the sampling storage device 5, referring to Figure 3 and Figure 4 , the water inlet device 3 includes a cylindrical pipe 31 fixedly connected to the lower end of the outer tube 1, four filter screens 32 are annularly arranged on the outer surface of the cylindrical pipe 31, a circular block 33 is slidably connected to the inner cavity of the cylindrical pipe 31, a slide rod 34 is fixedly connected to the upper end of the circular block 33, and a limiting plate 35 is fixedly connected to the upper end of the slide rod 34.

[0038] The slide rod 34 slides in the inner cavity of the outer tube 1.

[0039] In the above, when the device is lowered to the required sampling depth, the slide rod 34 is lifted to drive the circular block 33 to slide upward in the inner cavity of the cylindrical pipe 31, so that the circular block 33 is removed from the isolation outside the cylindrical pipe 31. The water will enter the cylindrical pipe 31 from the filter screen 32 and then enter the sampling storage device 5 for storage.

[0040] In the above, the filter screen 32 filters the impurities in the water, so that the impurities in the water cannot enter the cylindrical pipe 31, affecting the subsequent detection results.

[0041] In the above, the limiting plate 35 can limit the distance of the sliding rod 34 descending, so that the circular block 33 can exactly isolate the filter screen 32 and the water, so that the sewage cannot enter the cylindrical pipe 31 before it descends to the required sampling depth.

[0042] Further, in order to achieve the purpose of taking out the sampling storage device 5 from the inside of the device after sampling is completed, referring to Figure 5 and Figure 6 , the sampling storage device 5 includes a sampling bin 51 and two rectangular shells 52, the sampling bin 51 slides in the lower part of the inner cavity of the cylindrical pipe 31, the two rectangular shells 52 are fixedly connected to the lower left and right sides of the outer surface of the cylindrical pipe 31, the ends of the two rectangular shells 52 away from each other are slidingly connected with pull rings 53, the outer surfaces of the two pull rings 53 close to each other are fixedly connected with connecting plates 55, and the ends of the two connecting plates 55 away from each other are fixedly connected with pressure springs 54.

[0043] The two pull rings 53 penetrate through the outer surfaces of the cylindrical pipe 31 and the sampling bin 51 on the lower left and right sides and are slidingly connected therewith.

[0044] In the above, after the water enters the cylindrical pipe 31 from the filter screen 32, it will enter the sampling bin 51 for storage, and when the water amount for detection is reached, the device is first taken out of the sewage, and then the pressure spring 54 is driven to release the fixation between the sampling bin 51 and the cylindrical pipe 31, so that the sampling bin 51 is taken out, and the sampled water in the sampling bin 51 is detected.

[0045] In the above, when the pull ring 53 is pulled, the connecting plate 55 moves together in the inner cavity of the rectangular shell 52, and the connecting plate 55 compresses the pressure spring 54 to generate pressure when it moves, and when the sampling bin 51 is taken out, the pull ring 53 is loosened, so that the pressure spring 54 releases the pressure and pushes the connecting plate 55 to return to the original position, and the connecting plate 55 pulls the pull ring 53 to return to the original position.

[0046] In the above, through the design of the dome of the pull ring 53, when the sampling bin 51 is re-engaged into the cylindrical pipe 31, it only needs to be directly pushed in, and the specific movement process is consistent with the above.

[0047] Further, in order to achieve the purpose of scraping the impurities attached to the surface of the filter screen 32 by the scraping device 2, referring to Figure 7 and Figure 8 , the scraping device 2 includes a sliding ring 21 fixedly connected to the lower part of the outer surface of the outer pipe 1, a scraper 23 slidingly connected in the inner cavity of the sliding ring 21, and a push rod 22 fixedly connected to the upper end of the rear end of the scraper 23.

[0048] The front part of the scraper 23 is in close contact with the outer surface of the filter screen 32.

[0049] In the above, by pushing the push rod 22, the push rod 22 drives the scraper 23 to slide in the inner cavity of the sliding ring 21, so that the scraper 23 scrapes off the impurities attached to the outer surface of the filter screen 32, so that the impurities cannot block the filter screen 32 and affect the subsequent sampling.

[0050] The basic principle and main features of the present application and the advantages of the present application are shown and described above. Those skilled in the art should understand that the present application is not limited by the above examples, and the above examples and descriptions in the specification are only to illustrate the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the present application. The scope of protection of the present application is defined by the appended claims and their equivalents.
