The heavy filter media is quartz sand, activated carbon and other heavy materials with sedimentation properties. The filter media has a certain active use cycle. When the filter media is inactivated after completing an active use cycle and can no longer be used, it is necessary to replace the filter media on a large scale or in part. During the use cycle, in order to judge the performance of the filter media, sampling and testing are usually used to obtain various performance parameters of the filter media. Due to the cumbersome sampling steps, small single collection volume, uneven sampling and other reasons, water plant staff often make rough judgments based on the use time, and the results are not accurate.

[0020] The specific implementation of the present utility model is described below in conjunction with the accompanying drawings.
[0021] like Figure 1 As shown, the filter material sampling device of the filter tank includes a mobile bracket 1, and walking wheels 4 are respectively arranged at the four corners of the lower end of the mobile bracket 1. The arrangement of the walking wheels 4 enables manual pushing of the mobile bracket 1. A rotating shaft 3 is arranged on the upper end surface of the mobile bracket 1, and one end of a cantilever beam 2 is rotatably connected to the rotating shaft 3 through a shaft sleeve, and the cantilever beam 2 can rotate around the rotating shaft 3 to adjust the position.
[0022] like Figure 1 As shown, a mounting plate 5 is fixed to the lower end surface of the other end of the cantilever beam 2, a lifting cylinder 6 is vertically fixed on the mounting plate 5, a driving end of the lifting cylinder 6 is connected to a lifting frame 9, and the lifting cylinder 6 can drive the lifting frame 9 to move up and down.
[0023] like Figure 1 and Figure 2 As shown, a central sampling tube 10 is vertically fixed at the center of the lower end of the lifting frame 9, and four radial sampling tubes 13 that can move radially are arranged on the lower end surface of the lifting frame 9. The four radial sampling tubes 13 that can move radially are distributed along the circumferential direction. When the lifting frame 9 descends, the central sampling tube 10 and the four radial sampling tubes 13 are driven to enter the filter tank for sampling at the same time, and when the lifting frame 9 rises, the central sampling tube 10 and the four radial sampling tubes 13 that have been sampled are driven to leave the filter tank.
[0024] like Figure 2 and Figure 3 As shown, four radial slide rails 11 are arranged on the lower end surface of the lifting frame 9, and the four radial slide rails 11 are equidistantly distributed along the circumferential direction. A radial slider 12 is arranged on the top of each of the four radial sampling tubes 13, and the four radial sliders 12 are slidably connected to the four radial slide rails 11, so that the four radial sampling tubes 13 can adjust the sampling position along the radial direction, thereby meeting the sampling requirements of filter tanks of different sizes and shapes.
[0025] like Figure 1 and Figure 2As shown, the lower end surface of the mounting plate 5 is fixedly connected to four guide rods 7, which are distributed around the lifting cylinder 6, and the lower ends of the four guide rods 7 are respectively slidably connected to four guide sleeves 8, which are fixed to the lifting frame 9. The cooperation between the guide rods 7 and the guide sleeves 8 guides the lifting of the lifting frame 9, thereby ensuring the stability of the lifting frame 9 during the lifting process.
[0026] like Figure 2 and Figure 3 As shown, the lifting frame includes an outer ring plate 9.1 of a circular ring structure, a center plate body 9.2 is arranged at the center of the outer ring plate 9.1, and the center plate body 9.2 and the outer ring plate 9.1 are connected into one body through four radially arranged connecting plates 9.3, and four radial slide rails 11 are respectively fixed on the lower end surfaces of the four connecting plates 9.3, and the four connecting plates 9.3 are evenly distributed along the circumferential direction. An intermediate ring plate 9.4 of a circular ring structure is arranged between the outer ring plate 9.1 and the center plate body 9.2, and four guide sleeves 8 are fixed on the intermediate ring plate 9.4.
[0027] like Figure 4 As shown, three sampling ports 14 are arranged on the side of the central sampling tube 10, and the three sampling ports 14 are evenly spaced from top to bottom. Three independent sampling cavities 15 are arranged in the central sampling tube 10, and the three sampling ports 14 are connected to the three sampling cavities 15 one by one.
[0028] In order to make it easier for the filter material to enter the sampling cavity 15 through the sampling port 14, as shown in FIG. Figure 4 As shown, the sampling port 14 is tilted from outside to inside and from top to bottom. Such a design also makes it difficult for the filter material in the sampling cavity 15 to fall out of the sampling port 14 .
[0029] like Figure 4 As shown, a sharp guide head 16 is provided at the lower end of the central sampling tube 10, and the central sampling tube 10 can be more conveniently inserted into the filter material through the guide head 16. A mounting block 17 is provided at the upper end of the central sampling tube 10, and the central sampling tube 10 is installed through the mounting block 17.
[0030] like Figure 5 As shown, the radial sampling tube 13 and the central sampling tube 10 have exactly the same structure.
[0031] The working principle of the utility model is: when sampling the filter material in the filter tank, the mobile bracket 1 is pushed to the vicinity of the filter tank, and the lifting frame 9 reaches the top of the filter tank. The radial positions of the four radial sampling tubes 13 are adjusted according to the shape and size of the sampling filter tank. Then the lifting cylinder 6 is controlled to descend, and the lifting cylinder 6 drives the lifting frame 9 to descend, so that the central sampling tube 10 and the four radial sampling tubes 13 are inserted into the filter material of the filter tank for sampling, and the filter materials of different thickness layers enter the three sampling ports 14 respectively, and finally remain in the sampling cavity 15. Then the lifting cylinder 6 is controlled to rise, so that the central sampling tube 10 and the four radial sampling tubes 13 leave the filter tank, and the sampling is completed.
[0032] The above description is an explanation of the utility model, not a limitation of the utility model. The scope of the utility model is defined by the claims. Any form of modification can be made within the protection scope of the utility model.
