[0004] However, in actual use, the gap between the pipeline penetrating the roof and the building roof is still prone to liquid leakage, and the waterproof performance needs to be improved. SUMMARY

[0005] In order to improve the problem that liquid leakage easily occurs at the pipeline penetrating the roof, the present application provides a high-safety waterproof structure of residential building roof.

[0006] The present application provides a high-safety waterproof structure of residential building roof, which adopts the following technical scheme:

[0010] By the above technical scheme, the adjusting member is provided with the adjusting gear set and the abutting part, when the floating block moves upward and engages with the adjusting gear set, the floating block continues to move to make the adjusting gear set rotate, the rotation of the adjusting gear set makes the abutting part move towards the direction close to the axis of the pipe body, the movement of the abutting part pushes the sealing ring I against the pipe body, which improves the sealing between the waterproof sleeve and the pipe body and reduces the liquid seepage.

[0011] Further, the side wall of the collecting tank is provided with a drainage groove, and the drainage groove is connected with the collecting tank and the outside.

[0012] By the above technical scheme, in actual use, when the drainage groove is in an overflow state, the floating block makes the adjusting gear set rotate to the state that the abutting part abuts against the sealing ring I, and this state is maintained for a long time until the liquid evaporates to a certain degree, and when the actual liquid leakage occurs, it is often a climate with heavy rain, therefore, the drainage groove is provided, when the drainage speed is less than the collecting speed of the collecting tank, the floating block moves away from the bottom of the collecting tank, such setting also reduces the situation that the abutting part abuts against the sealing ring I for a long time and causes the sealing ring I to maintain deformation, and improves the service life of the sealing ring I.

[0013] Further, one end of the roof body close to the waterproof sleeve is provided with a waterproof layer and a waterproof layer II, the waterproof layer II is located above the waterproof layer I, and the end of the waterproof sleeve close to the waterproof layer abuts against the waterproof layer II.

[0018] Through the technical scheme, in actual use, there is a situation that the rainstorm weather roof liquid cannot be discharged in time, which may cause the roof liquid to gather, and the liquid gathering makes the liquid level higher than the inclined surface one, so there is a situation that the liquid moves to the pipe body through the gap between the inclined surface one and the inclined surface two, therefore, the control rack and the control part are arranged, when the liquid collecting speed of the liquid collecting groove is greater than the water draining speed of the water draining groove, the liquid level rises to make the floating block move upward, the floating block moves upward to drive the adjusting gear set to rotate, the adjusting gear set rotates to make the control rack move towards the inclined surface one, and the control part pushes the sealing ring two to tightly contact the inclined surface one, thereby reducing the liquid leakage and improving the overall waterproof effect.

The abutting part 19 is located on the side of the floating block 13 close to the axis of the pipe body 2, and the abutting part 19 engages with the adjusting gear set 18. When the floating block 13 moves upwards and causes the adjusting gear one 181 to rotate, the adjusting gear one 181 drives the adjusting gear two 182 to rotate, and the rotation of the adjusting gear two 182 causes the abutting part 19 to push the sealing ring one 10 to abut against the pipe body 2. In actual use, the side wall of the liquid collecting groove 12 is provided with a drainage groove 23, and the drainage groove 23 is connected to the outside world. The drainage groove 23 is used to drain the liquid in the liquid collecting groove 12 to reduce the accumulation of liquid, so that the sealing ring one 10 maintains the state of abutting against the pipe body 2, which easily causes the sealing ring one 10 to maintain deformation, resulting in a decrease in subsequent sealing effect.

[0042] The waterproof sleeve 6 is provided with a sealing ring groove two 21, which is located at one end of the waterproof sleeve 6 close to the inclined surface one 5. The sealing ring groove two 21 is provided with a sealing ring two 22, which protrudes from the inclined surface two 7 at the end away from the groove bottom of the sealing ring groove two 21.

The mounting cavity 14 is provided with a control rack 24 and a control part 25. The control rack 24 is engaged with the adjusting gear one 181. The control part 25 is located at one end of the control rack 24 close to the sealing ring two 22. The control part 25 abuts against the sealing ring two 22.

[0043] When the float 13 moves upward and rotates the adjusting gear one 181, the adjusting gear one 181 rotates to move the control rack 24 towards the inclined surface one 5 and push the control part 25 to abut against the sealing ring two 22.

[0044] The side of the sealing ring one 10 close to the inclined surface one 5 is provided with an inclined groove 26, which is located in the inner wall of the waterproof sleeve 6 and extends towards the waterproof layer one 3 in the direction away from the axis of the pipe body 2. When the liquid moves from the gap between the sealing ring one 10 and the pipe body 2 towards the inclined surface one 5, the liquid is affected by the inclined groove 26 and moves towards the groove bottom of the inclined groove 26. The groove bottom of the inclined groove 26 is provided with a control groove 27, which extends horizontally. The control groove 27 is provided with an expansion piece 28, which is used to push the sealing ring three 11 to abut against the outer wall of the pipe body 2.

[0045] The expansion piece 28 includes a water-heating block 281, a heat-expanding block 282 and a push plate 283. The heat-expanding block 282 is located between the water-heating block 281 and the push plate 283. The water-heating block 281 is located at one end of the heat-expanding block 282 away from the axis of the pipe body 2. The water-heating block 281 abuts against the heat-expanding block 282. The push plate 283 is connected to the heat-expanding block 282 and is used to abut against the sealing ring three 11. When the liquid flows into the control groove 27 through the inclined groove 26, the liquid contacts the water-heating block 281 and makes the water-heating block 281 heat up. The heating of the water-heating block 281 causes the heat-expanding block 282 to expand. The expansion of the heat-expanding block 282 pushes the push plate 283 to move, so that the sealing ring three 11 abuts against the outer wall of the pipe body 2.

[0046] In actual use, the water-heating block 281 is made of quicklime, and the heat-expanding block 282 is made of polyvinyl chloride. Alternatively, the heat-expanding block can also be made of rubber.

[0047] The push plate 283 is provided with a limiting groove 1 29 located at one end of the push plate 283 away from the inclined surface 1, and the groove bottom of the limiting groove 1 29 is provided with a limiting spring 30 connected with a limiting block 31 located at one end of the limiting spring 30 away from the groove bottom of the limiting groove 1 29, and the elastic force of the limiting spring 30 limits the movement of the limiting block 31 towards the groove bottom of the limiting groove 1 29. The cavity wall of the mounting cavity 14 is provided with a limiting groove 2 32 for embedding the limiting block 31.

[0048] When the liquid contacts the water-heating block 281 and makes the water-heating block 281 heat, the water-heating block 281 heats to make the heat-expanding block 282 expand, the heat-expanding block 282 expands to push the push plate 283 to move, the movement of the push plate 283 makes the limiting groove 1 29 communicate with the limiting groove 2 32, and the elastic force of the limiting spring 30 makes the limiting block 31 embedded in the limiting groove 2 32.

[0049] The working principle of the embodiment is as follows:

[0050] In actual use, the liquid enters the liquid collecting groove 12, the liquid makes the floating block 13 move upwards, the movement of the floating block 13 drives the adjusting gear 1 81 to rotate, the rotation of the adjusting gear 1 81 drives the control rack 24 to move towards the inclined surface 1, the control rack 24 pushes the control part 25 to move and makes the sealing ring 2 2 tightly abut against the inclined surface 1, and in this way, the situation that the liquid moves from the gap between the inclined surface 1 and the inclined surface 2 7 to the gap between the pipe body 2 and the top of the house body 1 is reduced. The rotation of the adjusting gear 1 81 drives the adjusting gear 2 82 to rotate, and the rotation of the adjusting gear 2 82 makes the abutting part 19 push the sealing ring 1 0 to tightly abut against the pipe body 2.

[0051] When the liquid enters from the gap between the waterproof sleeve 6 and the pipe body 2 and leaks out from the abutment of the sealing ring 1 and the tank body, the liquid is affected by the chute 26, part of the liquid moves towards the chute 26 groove bottom and enters the control groove 27. At this time, the water-heating block 281 heats to make the heat-expanding block 282 expand, the heat-expanding block 282 expands to push the push plate 283 to move, the movement of the push plate 283 makes the limiting groove 1 29 communicate with the limiting groove 2 32, and the elastic force of the limiting spring 30 makes the limiting block 31 embedded in the limiting groove 2 32.

[0052] The above are the preferred embodiments of the present application, which do not limit the protection scope of the present application, so that: any equivalent changes made on the structure, shape and principle of the present application shall be covered within the protection scope of the present application.
