The round rod 33 penetrates and is slidably connected to the upper surface of the leaking plate 7. A sealing plate 31 is fixedly connected to the lower surface of the round rod 33. When an explosion occurs, the impact force of the explosion will push the sealing plate 31 to move upward for sealing to prevent leakage of toxic gas. The sealing plate 31 is slidably connected to the inner wall at the bottom end of the floor drain seat body 1. Holes are provided at the intersecting positions of the sealing plate 31 and the sealing block 32 to ensure that the liquid can flow out smoothly. The upper surface of the sealing plate 31 is fixedly connected with sealing blocks 32 in multiple groups. The sealing blocks 32 are in contact with the inner wall of the leaking plate 7. Multiple groups of sealing blocks 32 correspond to each hole of the leaking plate 7 to ensure the sealing effect.

[0032] Reference Figure 1 - Figure 2 The protective component includes a floor drain plate 21, and a plurality of groups of holes are opened on the upper surface of the floor drain plate 21. External water will enter the interior of the floor drain seat body 1 through the holes opened therein and be discharged. The floor drain plate 21 slides on the inner wall of the top of the floor drain seat body 1, and the right end of the floor drain plate 21 slides on the inner wall of the slide groove 6.

[0033] Reference Figure 1 , Figure 3The upper surface of the round rod 33 is fixedly connected with a wedge block 34. When the sealing plate 31 moves, the round rod 33 drives the wedge block 34 to move to ensure the stability of its movement. The lower surface of the round rod 33 contacts the upper surface of the leaking plate 7. The left and right surfaces of the wedge block 34 are both set as inclined surfaces. The set inclined surfaces ensure that it can move upward smoothly and push the multiple groups of moving blocks 37 to move. The sealing assembly also includes a rectangular shell 35. The rectangular shell 35 is fixedly connected to the right side of the inner wall of the top of the floor drain seat body 1 near the lower surface of the drainage ring 4. The inner wall of the rectangular shell 35 is elastically connected to the moving block 37 through the spring 2 36. The spring 2 36 is elastically connected to the moving block 37 through its own elastic The movable block 37 is always pushed to the left to ensure that when the wedge block 34 rises, it can push the movable block 37 to reset and limit the wedge block 34 through its own elasticity. The movable block 37 is slidably connected to the inner wall of the rectangular shell 35, one end of the spring 36 is fixedly connected to the inner wall of the rectangular shell 35, and the other end of the spring 36 is fixedly connected to the right surface of the movable block 37. The left surface of the movable block 37 contacts the right surface of the wedge block 34, and the left end of the upper surface of the movable block 37 is fixedly connected with a push block 38. The left surface of the movable block 37 is set as an inclined surface, and the set inclined surface is adapted to the inclined surface of the wedge block 34 to ensure that the wedge block 34 can move smoothly.

[0034] Reference Figure 2 , Figure 4 The inner wall of the right end of the floor drain plate 21 is elastically connected with a block 23 through a spring 24. The spring 24 always pushes the block 23 to move backward through its own elasticity to ensure the stability of the block 23 limit. The block 23 is slidably connected to the inner wall of the right end of the floor drain plate 21. The rear surface of the block 23 is set as an inclined surface to ensure that the floor drain plate 21 can move downward smoothly. At the same time, the inclined surface of the block 23 is roughened to ensure the stability of its limit. It takes force to push the floor drain plate 21 downward. One end of the spring 24 is fixedly connected to The inner wall of the right end of the floor drain plate 21, the other end of the spring 24 is fixedly connected to the front surface of the block 23, the upper surface of the right end of the floor drain plate 21 is slidably connected with a push plate 22, the push plate 22 can only move forward or backward, the lower surface of the push plate 22 is fixedly connected to the front end of the upper surface of the block 23, the inner wall of the slide 6 is provided with limiting grooves 5 and the number is multiple groups, the limiting grooves 5 are provided with two groups, one group is the limit when the drainage ring 4 is not sealed, and the other group is the limit when the drainage ring 4 is sealed, and the rear end of the block 23 contacts the inner wall of the limiting groove 5.

[0035] Working principle: In the normal drainage state, external water enters the interior of the floor drain seat body 1 through the holes on the floor drain plate 21, and the water flows through the multiple groups of holes on the leakage plate 7 to play a filtering role. At the same time, due to the presence of the drainage ring 4, a certain amount of water is guaranteed not to be drained out, forming a water seal, which improves practicality.

[0036] In the sealed protection state, when encountering an explosion, the strong impact force will push the sealing plate 31 to move upward. At this time, multiple groups of sealing blocks 32 will be in close contact with the inner wall of the leaking plate 7, corresponding to each hole of the leaking plate 7, to achieve a good sealing effect and avoid leakage of toxic gas. When the sealing plate 31 moves, the wedge block 34 is driven to move upward through the round rod 33. The inclined surface on the wedge block 34 interacts with the inclined surface on the left surface of the moving block 37, pushing the moving block 37 to move right and compressing the second spring 36. When the wedge block 34 continues to rise to a certain position, the second spring 36 pushes the moving block 37 to move left to limit the wedge block 34 and maintain the sealed state. The seal of the sealing block 32 needs to be contacted. The floor drain plate 21 and the sealing bowl 25 are removed, and the push block 38 is pushed until the moving block 37 is separated from the wedge block 34, so that the sealing plate 31 will be lowered by gravity.

[0037] When the drain ring 4 needs to be sealed, simply press the floor drain plate 21, and the block 23 will move forward along its own inclined surface and squeeze the spring 24, while separating from the inner wall of the limiting groove 5, until the block 23 overlaps with another set of limiting grooves 5. At this time, the spring 24 will push the block 23 to move in the opposite direction and insert into the inner wall of the other set of limiting grooves 5 through its own elasticity, so that the sealing bowl 25 will contact the drain ring 4 and seal it. When disassembling, push the push plate 22 to separate the block 23 from the inner wall of the limiting groove 5, and then directly pull the floor drain plate 21.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
