[0033] Refer to Figures 1 to 8 .

[0034] The present invention provides a device for sealing a reserved hole for a pool full water test, comprising a threaded rod 1, and a pressing airbag 2, a first sealing block 3, an inflatable airbag 4, a second sealing block 5, and a threaded ring 6, which are arranged in sequence.

[0035] The threaded rod 1 is arranged horizontally, and one end of the threaded rod 1 is connected to the sealing side of the first sealing block 3, and the other end is passed through the second sealing block 5. The threaded ring 6 is threadedly connected to the threaded rod 1, and the inflatable airbag 4 is arranged on the outside of the threaded rod 1. The pressing airbag 2 is arranged on the water-contacting side of the first sealing block 3 and is connected to the inflatable airbag 4 through a one-way valve, and a makeshift hole 501 is provided on the second sealing block 5 for the inflation tube of the inflatable airbag 4 to pass through.

[0036] The reserved hole sealing device for the pool full water test of the present invention is provided with a threaded rod 1, a pressing airbag 2, a first sealing block 3, an inflatable airbag 4, a second sealing block 5 and a threaded ring 6. When the reserved hole is sealed, the sealing side of the first sealing block 3 is first attached to the inner wall of the pool and the threaded rod 1 is located in the reserved hole. Then, the second sealing block 5 is attached to the outer wall of the pool and is passed through the threaded rod 1. At the same time, the inflation tube of the inflatable airbag 4 is passed through the clearance hole 501 and then threadedly connected to the threaded rod 1 through the threaded ring 6. The threaded ring 6 is rotated to shorten the distance between the first sealing block 3 and the second sealing block 5 so that the two are tightly fitted to the pool wall. Finally, the inflatable airbag 4 is inflated to seal the reserved hole. When the pool of the present invention is filled with water, the water pressure squeezes the first block 3. The airbag 2 is pressed against the inner wall of the pool to prevent leakage. At the same time, the water pressure can also squeeze the pressing airbag 2, so that the gas in the pressing airbag 2 enters the inflatable airbag 4 through the one-way valve, further filling the inflatable airbag 4 to seal the reserved holes, preventing water from flowing out of the reserved holes. It has a double sealing structure with good sealing effect. In the present invention, a one-way valve is provided to only allow the gas in the pressing airbag 2 to pass into the inflatable airbag 4, and an inflation hole with a sealing plug is provided on the pressing airbag 2, which is convenient for re-inflating the pressing airbag 2 after testing. The inflatable airbag 4 can adopt the inflatable strip airbag structure for sealing the cable conduit in the prior art, and multiple layers can be wound around the outside of the threaded rod 1. At the same time, a waterproof sealing gasket 11 can also be provided on the sealing side of the first sealing block 3 and the second sealing block 5.

[0037] In one embodiment, a first locking mechanism 7 is further included for pre-fixing the first sealing block 3 to the reserved hole. This design prevents the first sealing block 3 from shifting when the second sealing block 5 is installed and the first and second sealing blocks 5 are fixed by the threaded ring 6, facilitating installation.

[0038] In one embodiment, the first locking mechanism 7 includes at least two symmetrically arranged first locking components, each of which includes a first screw rod 701 , a first bevel gear 702 , and a first locking plate 703 .

[0039] The first lead screw 701 is vertically arranged along the radial direction of the reserved hole in the first sealing block 3 and is rotatably connected to the first sealing block 3. The first helical gear 702 is arranged on the first lead screw 701. The first clamping plate 703 is inserted through the sealing side of the first sealing block 3, and the first clamping plate 703 is threadedly connected to the first lead screw 701 and slidably connected to the first clamping plate 703.

[0040] The threaded rod 1 is rotatably connected to the first sealing block 3. A second helical gear 8 is also rotatably arranged in the first sealing block 3. The second helical gear 8 is fixedly connected to the threaded rod 1 and meshes with the first helical gear 702. With this design, by rotating the threaded rod 1, the threaded rod 1 drives the second helical gear 8 to rotate, the second helical gear 8 drives the first helical gear 702 to rotate, and the first helical gear 702 drives the first lead screw 701 to rotate. Since the rotation of the first clamping plate 703 is restricted by the first sealing block 3, it can only move in the length direction of the first lead screw 701, that is, the two first clamping plates 703 move closer to or away from each other. When they move away from each other and the two first clamping plates 703 are attached to the inner wall of the reserved hole, the pre-fixing effect can be achieved. The operation is simple. And for the convenience of the subsequent fixing operation of the threaded ring 6, the first clamping plate 703 is attached to the inner wall of the reserved hole and is not in a tightly fitting state.

[0041] In an embodiment, the first clamping mechanism 7 further includes at least two recovery components corresponding to at least two of the first clamping components one by one, and the recovery components are used to receive the corresponding first clamping plates 703 into the first sealing block 3. With this design, when inflating the inflatable airbag 4, the first clamping plates 703 are first recovered into the first sealing block 3 through the recovery components, avoiding the first clamping plates 703 blocking the inflation of the inflatable airbag 4 and resulting in a poor sealing effect, and at the same time solving the problem of having a gap between the first clamping plates 703 and the reserved hole.

[0042] In one embodiment, the recovery assembly includes a second lead screw 704 rotatably disposed in the first sealing block 3 and perpendicular to the first lead screw 701, a first gear 705 disposed on the second lead screw 704, a rack 706 slidably disposed in the first sealing block 3 and meshing with the first gear 705, and a second gear 707 rotatably disposed in the first sealing block 3 and meshing with the rack 706. The first clamping plate 703 includes a fixed block 7031 disposed in the first sealing block 3 and a slider 7032 passing through the fixed block 7031, and the slider 7032 is threadedly connected to the second lead screw 704. With this design, when retracting the first clamping plate 703, by rotating the second gear 707, the rack 706 is driven to slide, and by the sliding of the rack 706, the first gear 705 is driven to rotate, realizing the rotation of the second lead screw 704. Since the rotation of the slider 7032 is restricted by the first sealing block 3, the slider 7032 can only move along the length direction of the second lead screw 704 to achieve contraction, and this structure does not hinder the pre-fixing operation of the first clamping plate 703, with a clever structure and simple operation. And in this embodiment, at least one ball that cooperates with the threaded ring 6 and facilitates the sliding of the first sealing block 3 along the depth direction of the reserved hole is rotatably disposed on the contact surface between the slider 7032 and the reserved hole. At the same time, two recovery assemblies are provided in this embodiment and are arranged parallel to each other at intervals along the depth direction of the reserved hole.

[0043] In one embodiment, the threaded rod 1 includes a first sleeve 101 provided with an external thread, a second sleeve 102 rotatably disposed in the first sleeve 101, and an operating rod 103 with a polygonal cross-section structure passing through the second sleeve 102. The second gear 707 is rotatably disposed in the first sealing block 3 through a connecting column 708, and a first slot 7081 matching the operating rod 103 is formed on the connecting column 708. The operating rod 103 passes through the second helical gear 8 and can be inserted into the first slot 7081. With this design, by sliding the operating rod 103 to fix it to the connecting column 708, the rotation operation of the connecting column 708 is realized, and then the recovery action of the recovery assembly is realized, and the pre-fixing operation of the first clamping plate 703 is not hindered.

[0044] In one embodiment, it further includes a second clamping mechanism 9 for pre-fixing the second sealing block 5 to the reserved hole. With this design, when the second sealing block 5 is sleeved on the threaded rod 1 and fixed by threaded connection through the threaded ring 6, the rotation and sliding of the second sealing block 5 are prevented, and the operation is inconvenient.

[0045] In one embodiment, the second card positioning mechanism 9 includes a fourth bevel gear 901, a connecting ring 902, and at least two symmetrically arranged second card positioning components. The second card positioning component includes a third lead screw 903, a third bevel gear 904, and a second clamping plate 905.

[0046] The third lead screw 903 is vertically arranged in the second sealing block 5 along the radial direction of the reserved hole and is rotatably connected to the second sealing block 5. The third bevel gear 904 is arranged on the third lead screw 903. The second clamping plate 905 is arranged on the sealing side of the second sealing block 5 in a penetrating manner, and the second clamping plate 905 is in threaded connection with the third lead screw 903 and is slidably connected to the second clamping plate 905.

[0047] The fourth bevel gear 901 is rotatably arranged in the second sealing block 5 and meshes with the third bevel gear 904. The fourth bevel gear 901 is sleeved on the outer side of the threaded rod 1. An activity groove 502 for the connecting ring 902 to pass through and rotate is formed in the second sealing block 5. The connecting ring 902 is sleeved on the outer side of the threaded rod 1, and the connecting ring 902 can pass through the activity groove 502 and be detachably connected to the fourth bevel gear 901. With such a design, by rotating the connecting ring 902, the connecting ring 902 drives the fourth bevel gear 901 to rotate, the fourth bevel gear 901 drives the third bevel gear 904 to rotate, and the third bevel gear 904 drives the third lead screw 903 to rotate. Since the rotation of the second clamping plate 905 is restricted by the second sealing block 5, it can only move in the length direction of the third lead screw 903, that is, the two second clamping plates 905 move closer to or away from each other. When they move away from each other and the two first clamping plates 703 are attached to the inner wall of the reserved hole, the pre-fixing effect can be achieved. The operation is simple. And for the convenience of the subsequent fixing operation of the threaded ring 6, the second clamping plate 905 is attached to the inner wall of the reserved hole but not in a tightly fitting state. And in this embodiment, at least one ball for cooperating with the threaded ring 6 and facilitating the sliding of the second sealing block 5 along the depth direction of the reserved hole is rotatably arranged on the contact surface between the second clamping plate 905 and the reserved hole.

[0048] In one embodiment, a groove 9011 for inserting the connecting ring 902 is formed in the fourth bevel gear 901, and a plurality of bolts 9012 are arranged in the groove 9011. A plurality of second slots 9021 matching the plurality of bolts 9012 are formed in the insertion side of the connecting ring 902, and the plurality of second slots 9021 and the plurality of bolts 9012 are in one-to-one corresponding plug-in cooperation. With such a design, the driving block of the second card positioning mechanism 9 can be detachably connected and is convenient for disassembly, preventing the pre-positioning failure of the second card positioning mechanism 9 caused by accidental contact with the driving block.

[0049] In one embodiment, a collar 10 is rotatably provided on one side of the threaded ring 6 adjacent to the second sealing block 5, and the collar 10 is sleeved on the outside of the threaded rod 1. With this design, with the collar 10 provided, when the connecting ring 902 is installed and the threaded ring 6 is tightened, the threaded ring 6 squeezes the connecting ring 902, and the collar 10 squeezes the second sealing block 5, resulting in a better locking effect. In this embodiment, when tightening, the collar 10 is located on the inner side of the connecting ring 902.

[0050] The specific operation method of the present invention is as follows: first, the blocking side of the first sealing block 3 is attached to the inner wall of the pool and the threaded rod 1 is located in the reserved hole; the threaded rod 1 is rotated to drive the first locking mechanism 7 to lock and pre-fix, the second sealing block 5 is installed, the inflation tube of the inflatable airbag 4 is passed through the clearance hole 501 and the second locking mechanism 9 is driven to lock and pre-fix; hold the first sleeve 101 and rotate the threaded ring 6 to fix it; hold the first sleeve 101 and push and rotate the operating rod 103 to retract the slider 7032, and finally inflate the inflatable airbag 4.

[0051] It should be understood that the examples and implementation methods described herein are for illustrative purposes only and are not intended to limit the present invention. Those skilled in the art may make various modifications or changes based on them. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
