In addition, the direction words mentioned in the following embodiments, such as “up”, “down”, “left”, “right” and the like are only the directions of the drawings, therefore, the direction words used are used for illustration but not for limiting the present application.

[0038] The present application will be further described below in combination with the drawings and the preferred embodiments.

[0039] Embodiment: A biological filter light filter material thickness measuring device, as shown in the drawings, Figure 1 - the drawings Figure 7 , including guide tube 1, support plate 2, measuring tube 3, sealing cover 4, measuring scale 9 and lifting mechanism 51, the position of the filter head installed on the filter plate of the filter is the installation hole, one end of the bottom of the guide tube 1 can pass through the installation hole and extend into the filter plate below; the support plate 2 is fixedly connected outside the guide tube 1 and can be supported on the top of the filter plate; the measuring tube 3 is set as a transparent measuring tube 3, the upper and lower ends of the measuring tube 3 are set as open, the measuring tube 3 can be inserted into the filter below the filter plate; the sealing cover 4 is detachably connected on the top of the measuring tube 3, when the sealing cover 4 is fixed on the top of the measuring tube 3, the top of the measuring tube 3 is sealed; the measuring scale 9 is used for measuring the thickness of the filter material in the measuring tube 3; the lifting mechanism 51 is used for driving the sealing cover 4 to move up and down.

[0040] ​Specifically, when the measuring tube 3 is inserted into the filter tank below the filter plate from top to bottom, the upper and lower ends are kept open until the bottom of the measuring tube 3 contacts the bottom of the filter tank; during the upward movement of the measuring tube 3 after contacting the bottom of the filter tank, the sealing cover 4 always seals the top end of the measuring tube 3.

[0041] When measuring, one filter head on the filter plate is removed, the bottom of the guide tube 1 is inserted into the filter tank below the filter plate through the mounting hole, the supporting plate 2 is supported on the top of the filter plate, and then the measuring tube 3 is vertically inserted into the filter tank below the filter plate in an open state from top to bottom until the bottom of the measuring tube 3 contacts the bottom of the filter tank. Then the top of the measuring tube 3 is sealed by the sealing cover 4, and then the sealing cover 4 is moved upward by the lifting mechanism 51 to drive the measuring tube 3 to move upward. Since the top of the measuring tube 3 is in a sealed state and the bottom of the measuring tube 3 is in the water below the filter screen at this time, the water and filter material in the measuring tube 3 will move upward with the measuring tube 3 and will not flow out of the bottom of the measuring tube 3 during the upward movement of the measuring tube 3. When the filter material in the measuring tube 3 moves above the filter screen, the thickness of the filter material in the measuring tube 3 is measured by the measuring scale 9 to obtain accurate filter material thickness data.

[0042] Specifically, the embodiment also includes a connecting assembly 6 for connecting the sealing cover 4 and the top of the measuring tube 3 together.

[0043] Specifically, the connecting assembly 6 includes a connecting ring 61 and a clamping ring 62. The connecting ring 61 is fixedly connected to the top outside of the measuring tube 3, and an annular connecting groove 611 is arranged around the connecting ring 61. The clamping ring 62 is provided with two annular structures smaller than a semicircle, and the two clamping rings 62 are arranged at the bottom of the sealing cover 4 with the open sides of the two clamping rings 62 located on the side where the two clamping rings 62 are close to each other. The two clamping rings 62 are slidably connected to the bottom of the sealing cover 4 and can move closer to or away from each other in the horizontal direction. When the two clamping rings 62 slide closer to each other, they can be clamped into the connecting groove 611 to connect the sealing cover 4 and the measuring tube 3.

[0044] When the sealing cover 4 is connected to the measuring tube 3, the sealing cover 4 is pressed onto the top of the measuring tube 3, and then the two clamping rings 62 slide towards each other to make the two clamping rings 62 clamped into the connecting groove 611, so that the sealing cover 4 can drive the measuring tube 3 to move upward during the upward movement of the sealing cover 4.

[0045] The bottom of the sealing cover 4 is provided with a sealing ring, which is pressed between the sealing cover 4 and the measuring tube 3 when the sealing cover 4 is fixed to the top of the measuring tube 3. The top of the inner side of the clamping ring 62 is provided with an inclined surface, which is inclined downward on the side close to the measuring tube 3, and the height of the top of the inclined surface is higher than the height of the top of the connecting groove 611.

[0046] By the setting of the inclined surface, when the two clamping rings 62 are inserted into the connecting grooves 611, the inclined surface will contact with the edge of the top sidewall of the connecting grooves 611 away from the axis of the measuring tube 3, and then the downward pressure can be applied to the sealing cover 4 under the action of the inclined surface, so that the sealing cover 4 is pressed tightly on the top of the measuring tube 3, and the sealing of the top of the measuring tube 3 is realized.

[0047] Specifically, two fixed blocks 63 are fixedly connected on the two sides of the sealing cover 4, and the two ends of the clamping ring 62 are located at the bottom of the two fixed blocks 63, respectively. The bottom of the fixed block 63 is provided with two sliding grooves 631 located at the top of the two clamping rings 62, respectively, and two sliding blocks 64 are arranged in the two sliding grooves 631, respectively. The sliding blocks 64 are arranged in the sliding direction of the clamping ring 62 in the sliding groove 631. The two clamping rings 62 are fixedly connected at the bottom of the two sliding blocks 64, respectively. The fixed block 63 is rotatably connected with a rotating rod 65, and the rotating rod 65 extends into the two sliding grooves 631. The length direction of the rotating rod 65 is arranged in the sliding direction of the clamping ring 62. The rotating rod 65 penetrates through the two sliding blocks 64 along the length direction of the rotating rod 65. The outer side of the rotating rod 65 is provided with two sections of external threads located in the two sliding grooves 631, respectively. The screw directions of the two sections of external threads are opposite and threadedly matched with the two sliding blocks 64, respectively.

[0048] By rotating the rotating rod 65, the two sliding blocks 64 can be simultaneously slid towards each other or away from each other, and then the two clamping rings 62 are slid towards each other or away from each other.

[0049] Specifically, the embodiment further includes a fixed ring 7, a winding rod 71, a clamping ring 8, and a fixed rod 81. The fixed ring 7 is fixedly connected to the top outer side of the guide tube 1. The winding rod 71 is rotatably connected to the outside of the fixed ring 7. The measuring scale 9 is arranged as a flexible measuring scale 9. The maximum scale end of the measuring scale 9 is fixedly connected to the winding rod 71, and the measuring scale 9 is wound on the winding rod 71. The clamping ring 8 is provided with two clamping rings 8 arranged as half circular rings. The two clamping rings 8 slide along the radial direction of the measuring tube 3 to realize approaching and moving away from each other, so as to realize clamping and loosening outside the measuring tube 3. The fixed rod 81 is fixedly connected to the outside of one of the clamping rings 8 and located directly above the winding rod 71. The zero scale end of the measuring scale 9 is fixedly connected to the fixed rod 81.

[0050] When the measuring tube 3 is pulled up, when the top of the filter material moves above the guide tube 1, the two clamping rings 8 are fixed outside the guide tube 1, and the zero scale of the measuring scale 9 is aligned with the top of the filter material. Then the measuring tube 3 continues to move upwards. In the process of moving upwards, the two clamping rings 8 can be driven to move upwards together until the bottom of the filter material moves above the guide tube 1. At this time, only the data of the measuring scale 9 aligned with the bottom of the filter material needs to be read to obtain the thickness of the filter material.

[0051] Specifically, the two ends of the clamping ring 8 are fixedly connected to two connecting blocks 82, and the connecting blocks 82 on the two clamping rings 8 correspond to each other. When the two clamping rings 8 are clamped outside the measuring pipe 3, the corresponding two connecting blocks 82 abut against each other. The corresponding two connecting blocks 82 are provided with a connecting rod 83 penetrating the two connecting blocks in the sliding direction of the clamping ring 8. The connecting rod 83 is externally provided with two sections of external threads in opposite screw directions, and the two sections of external threads are threadedly connected to the two connecting blocks 82, respectively.

[0052] By rotating the connecting rod 83, the two connecting blocks 82 can be simultaneously moved close to or away from each other, thereby driving the two clamping rings 8 to move close to or away from each other, so as to clamp and loosen the clamping ring 8 outside the measuring pipe 3.

[0053] Specifically, the embodiment further includes a support frame 5 fixedly connected to the top of the support plate 2, and the lifting mechanism 51 is a gas cylinder fixedly connected to the support frame 5.
