Based on the embodiments in this application, other similar embodiments obtained by ordinary technicians in this field without making creative work should all fall within the scope of protection of this application. In addition, the directional words mentioned in the following embodiments, such as "up", "down", "left", "right", etc., are only reference to the directions of the accompanying drawings. Therefore, the directional words used are used to illustrate rather than limit the invention.

[0019] The present invention will be further described below in conjunction with the accompanying drawings and preferred embodiments.

[0020] Embodiment: A device for measuring the thickness of light filter media in a biofilter, see the attached Figure 1 -Attached Figure 7 , including a guide tube 1, a support plate 2, a measuring tube 3, a sealing cover 4, a measuring ruler 9 and a lifting mechanism 51. The position for installing the filter head on the filter plate of the filter tank is a mounting hole, and the bottom end of the guide tube 1 can pass through the mounting hole and extend to the bottom of the filter plate; the support plate 2 is fixedly connected to the outside of 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, and the upper and lower ends of the measuring tube 3 are open. The measuring tube 3 can pass through the guide tube 1 and be inserted into the filter tank at the bottom of the filter plate; the sealing cover 4 is detachably connected to 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 ruler 9 is used to measure the thickness of the filter material in the measuring tube 3; the lifting mechanism 51 is used to drive the sealing cover 4 to move up and down.

[0021] Specifically, when the measuring tube 3 is inserted from top to bottom into the filter tank below the filter plate, 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 process of the measuring tube 3 moving upward after contacting the bottom of the filter tank, the sealing cover 4 always keeps the top end of the measuring tube 3 sealed.

[0022] When measuring, one of the filter heads on the filter plate is removed, and then the bottom of the guide tube 1 is inserted under the filter plate through the mounting hole, the support plate 2 is supported on the top of the filter plate, and then the measuring tube 3 is kept open at the top and bottom and inserted vertically downward through the guide tube 1 into the filter tank under the filter plate until the bottom of the measuring tube 3 contacts the bottom of the filter tank, and then the top of the measuring tube 3 is sealed by the sealing cover 4, and then the sealing cover 4 is driven 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 located in the water below the filter screen, when the measuring tube 3 moves upward, the water and filter material in the measuring tube 3 will move upward with the measuring tube 3 and will not flow out from the bottom of the measuring tube 3. When the filter material in the measuring tube 3 moves to above the filter screen, the thickness of the filter material in the measuring tube 3 is measured by the measuring ruler 9 to obtain accurate filter material thickness data.

[0023] Specifically, this embodiment further includes a connecting assembly 6 , and the connecting assembly 6 is used to connect the sealing cover 4 and the top of the measuring tube 3 together.

[0024] Specifically, the connecting assembly 6 includes a connecting ring 61 and a clamping ring 62. The connecting ring 61 is fixedly connected to the outer side of the top of the measuring tube 3.

The height of the top of the inclined surface is higher than the height of the top of the connecting groove 611.

[0027] By setting the inclined surface, when the two retaining rings 62 are inserted into the connecting groove 611, the inclined surface will contact the edge of the top side wall of the connecting groove 611 away from the axis of the measuring tube 3, and then, under the action of the inclined surface, downward pressure can be applied to the sealing cover 4, so that the sealing cover 4 is pressed against the top of the measuring tube 3, thereby achieving sealing of the top of the measuring tube 3.

The length direction of the rotating rod 65 is arranged along the sliding direction of the snap ring 62, and the rotating rod 65 passes through the two sliders 64 along its own length direction. Two sections of external threads are respectively located in the two sliding grooves 631 on the outside of the rotating rod 65, and the spiral directions of the two sections of external threads are opposite and respectively matched with the threads of the two sliders 64.

[0029] By rotating the rotating rod 65 , the two sliders 64 can be driven to slide toward or away from each other at the same time, thereby driving the two clamping rings 62 to slide toward or away from each other.

In the process of the measuring tube 3 moving upward, the two clamping rings 8 can be driven to move upward together until the bottom of the filter material moves above the guide tube 1. At this time, you only need to read the data when the measuring ruler 9 is aligned with the bottom of the filter material to obtain the thickness of the filter material.

[0032] Specifically, the two ends of the clamping ring 8 are fixedly connected to the 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 on the outside of the measuring tube 3, the corresponding two connecting blocks 82 fit together; the corresponding two connecting blocks 82 are provided with connecting rods 83 that penetrate the two clamping blocks along the sliding direction of the clamping ring 8, and the connecting rods 83 are provided with two sections of external threads with opposite spiral directions, and the two sections of external threads are respectively matched with the threads of the two connecting blocks 82.

[0033] By rotating the connecting rod 83 , the two connecting blocks 82 can be driven to move closer to or farther from each other at the same time, thereby driving the two clamping rings 8 to move closer to or farther from each other, thereby achieving the clamping and loosening of the clamping rings 8 outside the measuring tube 3 .
