The above device is not convenient for real-time observation of the water level height in the water seal groove 1, and cannot timely alarm and replenish water when the water level is low, which is not convenient for use". In terms of combined use, this problem is obviously a real problem that exists and is difficult to solve. In view of this, in order to solve this technical problem, a water level identification component 3 and a filter component 4 are added to the application document.

[0030] More specifically:

[0031] like Figure 1-Figure 4 As shown:

[0032] In combination with the above content, the water level marking assembly 3 includes a fixed box 31 installed inside the water seal groove 1, a benchmark 32 inserted inside the fixed box 31, and a floating plate 37 fixedly connected to the bottom end of the benchmark 32. An adjustment plate 33 is provided on the surface of the benchmark 32, a partition 36 is fixedly connected inside the fixed box 31, and a trigger switch 35 is symmetrically fixedly connected to the surface of the partition 36.

[0033] In this embodiment: when the device is in use, the fixing box 31 is first installed inside the water seal groove 1 through the mounting seat. When the water level inside the water seal groove 1 changes, the floating plate 37 is driven by the buoyancy of the water inside the water seal groove 1 to move the benchmark 32, so that the height of the water level inside the water seal groove 1 can be observed in real time through the mark on the benchmark 32. When the water level inside the water seal groove 1 is too low, the benchmark 32 can drive the adjustment plate 33 to move and squeeze the trigger switch 35 to trigger it, and the staff can be reminded to replenish water in time through the trigger switch 35.

[0034] It should be noted that a battery module is provided inside the trigger switch 35 to provide power for the operation of the trigger switch 35 . The trigger switch 35 is connected to an alarm so that the alarm can be controlled by the trigger switch 35 .

[0035] Going further:

[0037] In order to facilitate the adjustment of the preset alarm water level, in an optional embodiment: a movable groove is opened on the side of the partition 36 close to the benchmark 32, and a slide groove 34 is opened on the side of the fixed box 31 close to the adjustment plate 33; the surface of the benchmark 32 is marked with scale marks, and mounting seats are fixed at the four corners of the fixed box 31; the inside of the adjustment plate 33 is rotatably connected to a gear 311 through a rotating shaft, and a toothed plate 38 is inlaid on the side of the surface of the benchmark 32 close to the gear 311, and the gear 311 and the toothed plate 38 are meshingly connected; a worm wheel 310 is fixedly connected to one side of the gear 311, and a worm 39 is meshingly connected to the surface of the worm wheel 310, and one end of the worm 39 passes through the inside of the adjustment plate 33 and is fixedly connected to a handle set on the surface of the adjustment plate 33.

[0038] In this embodiment: when the alarm water level needs to be adjusted, the worm gear 310 can be driven to move by rotating the worm 39, and then the worm gear 310 will drive the gear 311 to roll on the surface of the tooth plate 38, and then can drive the adjustment plate 33 to move on the surface of the benchmark 32, adjust the height of the adjustment plate 33, change the trigger water level height of the adjustment plate 33 squeezing the trigger switch 35, and realize the adjustment of the alarm water level. The worm 39 and the worm gear 310 are self-locking to prevent the adjustment plate 33 from being driven by gravity to move the gear 311 on the surface of the tooth plate 38, thereby improving the stability of the adjustment of the adjustment plate 33.

[0039] It should be noted that when the mark rod 32 moves, it can drive the adjustment plate 33 to slide inside the slide groove 34, thereby increasing the stability of the movement of the mark rod 32.

[0040] More specifically:

[0041] like Figure 1-Figure 4 As shown:

[0042] In combination with the above content, a filter assembly 4 is provided on the surface of the fixed box 31, and the filter assembly 4 includes a fixed frame plate 44 installed at the bottom end of the fixed box 31 and a filter screen 41 fixedly connected to the fixed frame plate 44. A mounting groove is provided on the side of the fixed box 31 close to the fixed frame plate 44; a moving block 46 with a T-shaped structure is symmetrically provided on the side of the fixed box 31 close to the filter screen 41, a spring 45 is sleeved on the surface of the moving block 46, and a T-shaped insertion groove is provided on the side of the fixed box 31 close to the moving block 46, the top of the moving block 46 is rotatably connected to the limiting block 43, and a card slot 42 is provided on the side of the fixed frame plate 44 close to the limiting block 43.

[0043] In this embodiment: when the device is in use, the filter screen 41 can filter the water entering the fixed box 31, and the limit on the fixed frame plate 44 can be released by pulling the two sets of limit blocks 43 and rotating the limit blocks 43 to align with the card slots 42, and the filter screen 41 can be removed by pulling the fixed frame plate 44, and the fixed frame plate 44 is aligned with the installation slot, and the fixed frame plate 44 is pushed to slide into the interior of the fixed box 31, and then the limit block 43 is pulled to move upward, and the spring 45 is driven to contract by the moving block 46, and then the limit block 43 is flipped ninety degrees, and the limit block 43 will be limited to the fixed frame plate 44 by the elastic force of the spring 45, and the installation of the fixed frame plate 44 is completed, and the operation is simple and convenient.

[0044] Working principle: When the device is in use, firstly, the fixing box 31 is installed inside the water seal groove 1 through the mounting seat. When the water level inside the water seal groove 1 changes, the floating plate 37 is driven by the buoyancy of the water inside the water seal groove 1 to move the benchmark 32, so that the height of the water level inside the water seal groove 1 can be observed in real time through the mark on the benchmark 32. When the water level inside the water seal groove 1 is too low, the benchmark 32 can drive the adjustment plate 33 to move and squeeze the trigger switch 35 to trigger, and the trigger switch 35 can be used to promptly remind the staff to replenish water; when the alarm water level needs to be adjusted, the worm gear 310 can be driven to move by rotating the worm 39, and then the worm gear 310 will drive the gear 311 to roll on the surface of the tooth plate 38, thereby driving the adjustment plate 33 to move on the surface of the benchmark 32, adjusting the height of the adjustment plate 33, and changing the trigger water level height of the adjustment plate 33 squeezing the trigger switch 35. The worm 39 and the worm gear 310 are self-locking, so that the adjusting plate 33 is prevented from being driven by gravity to drive the gear 311 to move on the surface of the toothed plate 38, thereby improving the stability of the adjustment of the adjusting plate 33. The filter screen 41 can filter the water entering the fixed box 31. By pulling the two sets of limit blocks 43 and rotating the limit blocks 43 to align with the card slots 42, the limit on the fixed frame plate 44 can be released, and the fixed frame plate 44 can be pulled to remove the filter screen 41. By aligning the fixed frame plate 44 with the installation slot and pushing the fixed frame plate 44 to slide into the interior of the fixed box 31, and then pulling the limit block 43 to move upward, the spring 45 is driven to contract by the moving block 46, and then the limit block 43 is flipped ninety degrees. The limit block 43 will be limited to the fixed frame plate 44 by the elastic force of the spring 45, and the installation of the fixed frame plate 44 is completed. The operation is simple and convenient.
