[0032] The utility model provides Figure 1 A stable and clean hydrofluoric acid sampling device is shown, comprising a sampling bottle 4, and further comprising:

[0033] The device body 1 is arranged outside the sampling bottle 4 and is used to install and fix various components;

[0034] The adjusting mechanism 2 is arranged inside the device body 1 and below the sampling bottle 4, and is used to adjust the height of the sampling bottle 4;

[0035] The clamping and cleaning mechanism 3 is arranged on the top of the adjusting mechanism 2 and is used for clamping the sampling bottle 4 and cleaning the surface of the adjusting mechanism 2 .

[0036] In order to facilitate the installation and fixation of various components, such as Figure 2 and Figure 3 As shown, the device body 1 includes a fixed shell 101, a liquid inlet pipe 105 is movably inserted into the top of the inner wall of one end of the fixed shell 101, and a collecting box 106 is movably installed at the inner bottom of the fixed shell 101. Hydrofluoric acid can be sampled through the liquid inlet pipe 105, and the adjustment mechanism 2 and the clamping and cleaning mechanism 3 can be installed and fixed through the fixed shell 101.

[0037] In order to conveniently adjust the height of the sampling bottle 4, Figure 2 and Figure 4 As shown, the adjustment mechanism 2 includes a placement plate 201 and a rotating shaft 204, both sides of the outer wall of one end of the placement plate 201 are fixedly installed with movable racks 202, the inner wall of the placement plate 201 is provided with a plurality of seepage holes 207, the rotating shaft 204 is rotatably installed on the inner wall of one end of the fixed shell 101, a servo motor 205 is provided on one side of the rotating shaft 204, both sides of the outer walls of the rotating shaft 204 are fixedly sleeved with rotating gears 206, the two rotating gears 206 are respectively meshed with the two movable racks 202, the servo motor 205 works to rotate the rotating shaft 204, through the meshing action between the rotating gear 206 and the movable rack 202, the placement plate 201 is moved inside the fixed shell 101, and then the distance between the sampling bottle 4 and the liquid inlet tube 105 can be adjusted, and then sampling bottles 4 of different sizes can be used for sampling hydrofluoric acid, which can prevent hydrofluoric acid from splashing onto the outside of the sampling bottle 4.

[0038] In order to keep the sampling bottle 4 stable during the sampling process, Figure 2 and Figure 5As shown, the clamping and cleaning mechanism 3 includes a dual-axis motor 301, which is fixedly installed on the side of the placement plate 201 away from the inner wall of the fixed shell 101. The two output ends of the dual-axis motor 301 are both driven and installed with adjusting screws 302. The outer sides of the two adjusting screws 302 are both threadedly sleeved with clamping scrapers 303. The two clamping scrapers 303 are movably connected to the outer wall of the sampling bottle 4. The operation of the dual-axis motor 301 causes the two adjusting screws 302 to rotate, thereby allowing the two clamping scrapers 303 to clamp and fix sampling bottles 4 of different sizes, so that the sampling bottles 4 remain stable during the sampling process.

[0039] In order to keep the placement plate 201 stable during the adjustment process, Figure 2 and Figure 3 As shown, a movable door plate 102 is rotatably installed at one end of the opening side of the fixed shell 101, and a window 103 is provided on the inner wall of the movable door plate 102. Movable grooves 104 are provided on both sides of the inner wall of both ends of the fixed shell 101. Slide blocks 203 are fixedly installed on both sides of one end of the placement plate 201 away from the movable rack 202. The outer wall of the movable rack 202 is movably connected to the inner wall of the adjacent movable groove 104, and the outer wall of the slide block 203 is movably connected to the inner wall of the adjacent movable groove 104. The movable groove 104 can limit the movement of the movable rack 202 and the slide block 203, so that the placement plate 201 remains stable during the height adjustment process, and the height of the sampling bottle 4 can be stably adjusted.

[0040] In order to provide power for the height adjustment of the sampling bottle 4, as Figure 2 As shown, the inner wall of one end of the fixed shell 101 is fixedly connected to the servo motor 205, and the servo motor 205 is connected to the rotating shaft 204 through the output shaft transmission. The fixed shell 101 can install and fix the servo motor 205. The operation of the servo motor 205 causes the rotating shaft 204 to rotate. Through the meshing action between the rotating gear 206 and the movable rack 202, the height of the placement plate 201 can be adjusted, and then the distance between the sampling bottle 4 and the liquid inlet tube 105 can be adjusted.

[0041] In order to make the scraper 303 able to stably clean the placement plate 201, Figure 2 and Figure 4-5As shown, the clamping and cleaning mechanism 3 includes a limiting rod 304, which is fixedly installed on the outer wall of one side of the placement plate 201 close to the fixed shell 101, and the inner wall of the two clamping scrapers 303 on the side away from the adjusting screw rod 302 is movably connected to the outer walls at both ends of the limiting rod 304, and the bottoms of the two clamping scrapers 303 are movably connected to the two ends of the top of the placement plate 201, respectively. The limiting rod 304 can limit the movement of the clamping scraper 303, so that the clamping scraper 303 can stably clamp the sampling bottle 4, and at the same time, it can stably clean the top surface of the placement plate 201.

[0042] The specific implementation method is as follows: when performing hydrofluoric acid sampling, the sampling bottle 4 is placed on the top of the placement plate 201, and the two adjusting screw rods 302 are rotated by the dual-axis motor 301, so that the distance between the two clamping scrapers 303 can be adjusted, so that the two clamping scrapers 303 can clamp and fix the sampling bottle 4, and at the same time, the limiting rod 304 can limit the movement of the clamping scraper 303, so that the clamping scraper 303 remains stable during the adjustment process, and then the servo motor 205 is operated to rotate the rotating shaft 204, and then the two rotating gears 206 are rotated, and through the meshing action between the gear parts, the two movable racks 202 can move along the inner walls of the adjacent movable grooves 104, so that the height of the placement plate 201 can be adjusted, and then the distance between the sampling bottle 4 and the liquid inlet tube 105 can be adjusted. The distance can be adjusted, and at the same time, the connection between the movable groove 104 and the slider 203 can limit the movement of the placement plate 201, so that the placement plate 201 remains stable during the height adjustment process, and then hydrofluoric acid can be transported to the inside of the sampling bottle 4 through the liquid inlet pipe 105, which can prevent hydrofluoric acid from splashing out of the sampling bottle 4. The liquid that needs to be poured during the sampling process can be poured into the collection box 106 through the seepage hole 207. When the sampling is completed, the dual-axis motor 301 works to rotate the two adjusting screws 302, so that the clamping scraper 303 can clean the top surface of the placement plate 201, and the waste liquid can be recycled by taking out the collection box 106. This embodiment specifically solves the problem that the prior art cannot conveniently adjust the device according to the size of the sampling bottle 4, which makes it easy for hydrofluoric acid to splash during the sampling process.

[0043] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
