[0021] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0022] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0023] See also Figures 1 to 4 The embodiment of the utility model provides a sewage treatment plant sludge sampling device, which includes a sampling cylinder 1, a spiral plate 4 and a driving component 5.

[0024] In the embodiments of the present invention, please refer to Figures 1 to 4 A central connecting rod 6 is fixedly installed on the top of the sampling tube 1, and a sealing tube cover 2 is installed at the bottom tube mouth of the sampling tube 1 for elastic connection and sealing the tube mouth. Specifically, two symmetrically distributed insertion rods 21 are fixedly installed on the inner cover surface of the sealing tube cover 2, and the two insertion rods 21 are respectively inserted into two mounting holes 1a opened on the bottom end surface of the sampling tube 1 and are slidably connected to the mounting holes 1a. A tension spring 22 is installed in the mounting hole 1a, one end of the tension spring 22 is fixedly connected to the inner top wall of the mounting hole 1a, and the other end of the tension spring 22 is fixedly connected to the insertion end of the insertion rod 21.

[0025] It should be noted that: when the inner cover surface of the sealing cylinder cover 2 is not subjected to the downward pushing force of the rotating rod 3, the insertion rod 21 is driven to be inserted into the mounting hole 1a under the elastic force of the tension spring 22, so that the sealing cylinder cover 2 seals the bottom tube mouth of the sampling cylinder 1, and when the inner cover surface of the sealing cylinder cover 2 is subjected to the downward pushing force of the rotating rod 3, the insertion rod 21 slides down along the mounting hole 1a and stretches the tension spring 22, so that a cavity is left at the tube mouth of the sealing cylinder cover 2 and the sampling cylinder 1 to facilitate the sludge to enter the sampling cylinder 1.

[0026] In the embodiments of the present invention, please refer to Figures 1 to 4A rotating rod 3 connected in rotation is installed in the sampling tube 1, a spiral plate 4 is fixedly sleeved on the rotating rod 3, and the bottom of the rotating rod 3 is rotatably connected to the inner cover surface of the sealing tube cover 2, a driving assembly 5 for pushing down the rotating rod 3 and driving the rotating rod 3 to rotate is installed in the sampling tube 1, and the driving assembly 5 includes a servo motor 51, the servo motor 51 is fixedly installed on the inner top wall of the sampling tube 1, and a threaded rod 52 is fixedly installed at the output end of the servo motor 51, a plum blossom-shaped sliding hole 52a is opened on the threaded rod 52, and a plum blossom rod 53 connected in sliding connection is inserted in the plum blossom-shaped sliding hole 52a, and the end of the plum blossom rod 53 is fixedly installed with A connecting disk 59, and the lower disk surface of the connecting disk 59 is fixedly connected to the rotating rod 3, and the threaded rod 52 is sleeved with a threaded seat 56 with a threaded connection, and a fixedly connected abutment rod 58 is installed on the threaded seat 56, and the other end of the abutment rod 58 is rotatably connected to the upper disk wall of the connecting disk 59. Specifically, a rotatably connected rotating ring is installed on the connecting disk 59, and the connecting end of the abutment rod 58 is fixedly connected to the rotating ring, and two symmetrically distributed limiting rods 55 are fixedly installed on the inner top wall of the sampling tube 1, and each of the limiting rods 55 is sleeved with a slidably connected ring 57, and the two rings 57 are respectively fixedly connected to the two side walls of the threaded seat 56.

[0027] It should be noted that: the staff inserts the sampling tube 1 into the sludge pool by holding the middle connecting rod 6, and at this time, the sealing tube cover 2 is kept to seal the bottom tube mouth of the sampling tube 1, so that the sludge cannot enter the sampling tube 1. When the sampling tube 1 is inserted to the predetermined depth of the sludge pool (or inserted into the sludge at the specified acquisition depth), the servo motor 51 is turned on to drive the threaded rod 52 to rotate. Since the threaded seat 56 on the threaded rod 52 is limited by the limit rod 55, the threaded seat 56 can slide down along the threaded rod 52. Therefore, the abutting rod 58 on the threaded seat 56 can push down the rotating rod 3 under the connecting plate 59 and the spiral plate 4 on the rotating rod 3. Therefore, the lower rod head of the rotating rod 3 pushes down the sealing tube cover 2 to open a cavity between the sealing tube cover 2 and the bottom of the sampling tube 1.

[0028] At the same time, since the plum blossom rod 53 on the connecting plate 59 and the plum blossom-shaped sliding hole 52a in the threaded rod 52 can only slide up and down, the plum blossom rod 53 can rotate synchronously with the threaded rod 52, so the spiral plate 4 on the rotating rod 3 can introduce the sludge from the cavity between the sealing cylinder cover 2 and the sampling cylinder 1 into the sampling cylinder 1, so that the sewage station can flexibly sample and process the sludge at the required depth, avoiding the mixing of sludge at different depths during sampling, which affects the detection results;

[0029] After sampling is completed, the servo motor 51 is turned on to rotate in reverse so that the rotating rod 3 slides back to the sampling tube 1, and the sealing tube cover 2 can seal the bottom tube opening of the sampling tube 1 (a small amount of sludge will slip off during the process);

[0030] In addition, a drain valve 11 is installed on the sampling cylinder 1, and the drain valve 11 is located on the sampling cylinder 1 below the blocking disk 54. When the sampled sludge needs to be obtained, the drain valve 11 is opened and then the servo motor 51 is turned on for reverse rotation, so that the spiral plate 4 feeds the sludge upward and causes the sludge to overflow from the drain valve 11.

[0031] In this embodiment, since a rotating ring for rotational connection is installed on the connecting disk 59, and the connecting end of the abutting rod 58 is fixedly connected to the rotating ring, the abutting rod 58 will not restrict the rotation of the connecting disk 59;

[0032] Among them, the threaded seat 56 in this device has a tendency to slide to the end of the threaded rod 52 and rotate, so the threaded section of the threaded hole can be reduced in the threaded seat 56, thereby reducing the degree of wear.

[0033] In addition, the driving assembly 5 also includes a blocking disk 54, which is fixedly installed in the sampling tube 1, and the blocking disk 54 is sleeved on the end of the threaded rod 52 and is rotatably connected to the threaded rod 52, and the abutment rod 58 passes through the through hole opened in the blocking disk 54 and is slidably connected to the through hole. The blocking disk 54 can prevent sludge from entering the chamber where the servo motor 51 is installed, thereby avoiding the sludge from affecting the servo motor 5.

[0034] The working principle of the sewage station sludge sampling device provided by the utility model is as follows:

[0035] When the inner cover surface of the sealing cylinder cover 2 is not subjected to the downward push force of the rotating rod 3, the insertion rod 21 is driven to be inserted into the mounting hole 1a under the elastic force of the tension spring 22, so that the sealing cylinder cover 2 seals the bottom tube mouth of the sampling cylinder 1, and when the inner cover surface of the sealing cylinder cover 2 is subjected to the downward push force of the rotating rod 3, the insertion rod 21 slides down along the mounting hole 1a and stretches the tension spring 22, so that a cavity is left at the tube mouth of the sealing cylinder cover 2 and the sampling cylinder 1, so that the sludge can enter the sampling cylinder 1. The staff inserts the sampling cylinder 1 into the sludge pool by holding the middle connecting rod 6. At this time, the sealing cylinder cover 2 is kept to seal the bottom tube mouth of the sampling cylinder 1 The mouth is sealed, so the sludge cannot enter the sampling tube 1. When the sampling tube 1 is inserted into the predetermined depth of the sludge pool (or inserted into the sludge at the designated acquisition depth), the servo motor 51 is turned on to drive the threaded rod 52 to rotate. Since the threaded seat 56 on the threaded rod 52 is limited by the limit rod 55, the threaded seat 56 can slide down along the threaded rod 52. Therefore, the abutting rod 58 on the threaded seat 56 can push down the rotating rod 3 under the connecting plate 59 and the spiral plate 4 on the rotating rod 3. Therefore, the lower rod head of the rotating rod 3 pushes down the sealing tube cover 2 to open a cavity between the sealing tube cover 2 and the bottom of the sampling tube 1.

[0036] At the same time, since the plum blossom rod 53 on the connecting disk 59 and the plum blossom sliding hole 52a are provided in the threaded rod 52 and can only slide up and down, the plum blossom rod 53 can rotate synchronously with the threaded rod 52, so the spiral plate 4 on the rotating rod 3 can introduce the sludge from the cavity between the sealing cylinder cover 2 and the sampling cylinder 1 into the sampling cylinder 1, so as to realize the sewage station to flexibly sample and process the sludge of the required depth; after the sampling is completed, the servo motor 51 is turned on to reverse the rotation so that the rotating rod 3 slides back to the sampling cylinder 1, so that the sealing cylinder cover 2 can seal the bottom cylinder mouth of the sampling cylinder 1 (at this time, a small amount of sludge will slip off during the process); in addition, a drain valve 11 is installed on the sampling cylinder 1, and the drain valve 11 is located on the sampling cylinder 1 below the blocking disk 54. When the sampled sludge needs to be obtained, the drain valve 11 is opened and then the servo motor 51 is turned on to reverse the rotation, so that the spiral plate 4 feeds the sludge upward and causes the sludge to overflow from the drain valve 11.

[0037] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.

[0038] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
