DETAILED DESCRIPTION

[0019] The utility model is further described in detail below based on the accompanying drawings and specific embodiments.

[0020] Example

[0021] like Figure 1-3 A hole blocking device is shown, comprising a front tube 1, the middle part of which is covered with an air bag 2, the rear end of the front tube 1 is connected to a baffle plate 3, the rear end of the baffle plate 3 is connected to the air pumping hole of the rear tube 4, an air pumping rod 5 is arranged inside the rear tube 4, air holes are arranged on both sides of the baffle plate 3, one air hole is an air inlet hole, an air inlet device is arranged inside the baffle plate 3, the baffle plate 3 is connected to the rear tube 4 on the air inlet device side, the other air hole is an exhaust hole, an exhaust device is arranged inside the baffle plate 3, and the exhaust device is connected to the front tube 1 on the exhaust device side, and an exhaust switch 6 is arranged on the baffle plate 3.

[0022] Furthermore, the tube wall of the front tube 1 that wraps the airbag 2 is provided with air holes for inflating the airbag 2 .

[0023] Furthermore, the air intake device is composed of an air intake sealing ball 8 and an air intake spring 9. One end of the air intake sealing ball 8 is against the air intake hole of the baffle plate 3, and the other end is in contact with the air intake spring 9. When inhaling, the air flow pushes the air intake sealing ball 8 to press the air intake spring 9 to move backward, allowing air to enter. Under normal circumstances, the air intake sealing ball 8 blocks the air intake hole due to the elastic force of the air intake spring 9, so that the internal gas cannot escape.

[0024] Furthermore, the exhaust device is composed of an exhaust sealing ball 10 and an exhaust spring 11. One end of the exhaust sealing ball 10 is against the exhaust hole of the baffle plate 3, and the other end is in contact with the exhaust spring 11. Under normal circumstances, the exhaust sealing ball 10 blocks the air hole due to the elastic force of the exhaust spring 11, so that the internal gas cannot be discharged. When exhaust is needed, the exhaust switch 6 is pushed to press the exhaust sealing ball 10 downward to discharge the air.

[0025] Furthermore, an air-inflating sealing block 12 is provided in the air-inflating hole of the rear bobbin 4, and an air-inflating spring 13 is provided below the air-inflating sealing block 12. The air-inflating sealing block 12 is a circular sheet structure, and its diameter is larger than the air-inflating hole diameter of the air-inflating hole and smaller than the inner diameter of the air-inflating hole. When vacuuming, the air-inflating sealing block 12 closes the air-inflating hole, and when inflating, the air flow pushes the air-inflating sealing block 12 open, so that the air flow passes through the air-inflating hole to reach the front bobbin 1. Under normal circumstances, under the action of the air-inflating spring 13, the air-inflating sealing block 12 closes the air-inflating hole.

[0026] Furthermore, a sealing rubber ring 7 is provided on the front end of the pumping rod 5 to enhance airtightness and prevent leakage of the air stored in the rear tube 4.

[0027] The above-mentioned device is used in the following process: according to the requirements of underground mine drilling work, after the drilling is completed, the air pump 5 is pulled to suck the outside air into the rear tube 4, and the front tube 1 of the plugging device is placed in the drilled hole, the baffle plate 3 is pressed against the rock wall, and then the air pump 5 is pushed to the bottom to send the air in the rear tube 4 into the front tube 1. The air in the front tube 1 gradually increases, causing the air bag 2 to begin to expand and increase in diameter, and finally the air bag 2 fills the hole. If the hole is large, the air pumping operation can be repeated many times. After the plugging device fills the hole, the air pumping can be stopped. When all the holes are drilled, the exhaust switch 6 is lifted to discharge the air in the air bag 2 and the front tube 1. The air bag 2 shrinks and reduces in diameter, and then the plugging device can be smoothly taken out and recycled for reuse.
