[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to construct, the present invention is further described below in conjunction with specific implementation methods.

[0020] like Figure 1-4As shown in the figure, a dust-proof and hole-sealing integrated device includes a guide sleeve 1, a bearing tube 2, an elastic protective cover 3, a multi-way valve 5, a positioning screw 6, and a bearing bag 7. The guide sleeve 1 is a hollow cylindrical structure. There are several bearing tubes 2. The upper end surfaces of each bearing tube 2 are hinged to the outer side surface of the guide sleeve 1 through hinges, and each bearing tube 2 is evenly distributed around the axis of the guide sleeve 1. The axis of the bearing tube 2 forms an angle of 0° - 90° with the axis of the guide sleeve 1. The upper end surface of the bearing tube 2 is connected to the multi-way valve 5 through a diversion tube, and the lower end surface is connected to a positioning screw 6, and the bearing tube 2 and the positioning screw 6 are coaxially distributed. A number of through holes 8 are provided on the wall of the bearing tube 2 along its axis direction. At the same time, adjacent two bearing tubes 2 are connected through an elastic protective cover 3. And when the angle between the axis of the bearing tube 2 and the axis of the guide sleeve 1 is greater than 0°, the bearing tube 2 and the elastic protective cover 3 form a frustum-shaped cavity structure with an isosceles trapezoid axial section. The bearing bag 7 is wrapped outside the guide sleeve 1 and is a closed annular structure coaxially distributed with the guide sleeve 2. The bearing bag 7 is connected to the multi-way valve 5 through a diversion tube. At the same time, the outer side surface of the bearing bag 7 abuts against each bearing tube 2.

[0021] It should be emphasized that a support arm 9 is additionally provided outside the bearing tube 2. The support arm 9 includes a bearing groove 91, a connecting elastic sheet 92, and an elastic buckle 93. Among them, the bearing groove 91 is a groove-shaped structure with a cross-section in the shape of "冂". There are several bearing grooves 91. Each bearing groove 91 is coaxially distributed and adjacent two bearing grooves 91 are connected by a connecting elastic sheet 92. And the distance between adjacent two bearing grooves 91 is 0.5 - 1.5 times the length of the bearing groove 91. At least two elastic buckles 93 are provided in the bearing groove 91 along its axis direction, and the bearing tube 2 is wrapped outside through the elastic buckles 93. At the same time, the bearing groove 91 located at the rear end surface of the bearing tube 2 is hinged to the guide sleeve 1. At the same time, a connecting groove 94 parallel to the axis of the bearing tube 2 is provided on the side surfaces of both the bearing groove 91 and the connecting elastic sheet 92, and the side surfaces of the bearing groove 94 and the connecting elastic sheet 92 are connected to the side surface of the elastic protective cover 3 through the connecting groove 94.

[0022] By setting the support arm, the structural strength of the bearing tube can be effectively improved, and the reliability and stability of positioning between the bearing tube and the positioning screw and the drilling wall can be improved.

[0023] Further optimized, the elastic protective cover 3 is any one of a bellows plate structure and a flexible fabric structure.

[0024] In addition, an auxiliary driving mechanism 10 is provided outside the bearing bladder 7. The auxiliary driving mechanism 10 includes an assembly groove 101, an elastic hinge 102, a guide plate 103, and a guide pulley 104. The assembly groove 101 is an annular structure coaxially distributed with the guide sleeve 1, and its cross-section is a "U"-shaped groove structure. The lower half of the bearing bladder 2 is embedded in the assembly groove 101 and connected to the bottom of the assembly groove 101. At the same time, the bearing bladder 2 abuts against the groove wall of the assembly groove 101 near the rear end face of the bearing tube 2. At the same time, the width of the assembly groove 101 is 1.3 - 2 times the maximum width of the bearing bladder 2. The guide plate 103 is a plate-like structure with a rectangular cross-section. The number of guide plates 103 is the same as the number of bearing tubes 2. The rear end face of the guide plate 103 is hinged to the upper end face away from one end of the bearing bladder 2 through an elastic hinge 102. The lower end face of the front half is abutted against and slidably connected to the upper end face of the bearing bladder 2. At the same time, a guide pulley 104 is provided on the front end face of the guide plate 103, and the guide pulley 104 abuts against and slidably connects to the outer side surface of the bearing tube 2.

[0025] The provided auxiliary driving mechanism, when the bearing bladder expands in volume due to the injection of high-pressure medium, as the bearing bladder expands in volume, on the one hand, the outer diameter of the bearing bladder increases, and on the other hand, the width increases. When its outer diameter increases, the angle between the axis of the driving guide plate and the axis of the bearing bladder increases from the range of 0° - 90°. And as the angle between the axis of the driving guide plate and the axis of the bearing bladder increases, the front end face of the guide plate rises. During the rising process, the bearing tube is also driven to deflect accordingly, so that the angle between the axis of the bearing tube and the axis of the guide sleeve increases from the range of 0° - 90°, thereby realizing the simultaneous opening of each bearing tube. And when the bearing tubes open, on the one hand, the positioning screws connected to the front end faces of each bearing tube are inserted into the hole wall of the drilled hole; on the other hand, the elastic protective covers between adjacent two bearing tubes are also unfolded synchronously, realizing the flexible plugging of the drilled hole.

[0026] Further optimized, at least one disc spring 105 coaxially distributed with it is provided in the assembly groove 101. One end of the disc spring 105 abuts against the groove wall of the assembly groove 101 away from the bearing bladder 2, and the other end abuts against the side surface of the bearing bladder 2.

[0027] The provided disc spring can be compressed when the bearing bladder expands in volume, thereby accumulating elastic potential energy. And when the equipment is recovered after the drilling operation is completed, when the pressure in the bearing bladder decreases, the elastic potential energy accumulated by the disc spring realizes the axial compression of the slurry bladder.

[0028] Further optimized, a spring piece 106 and a columnar spring 107 are further provided on the lower end face of the front half of the guide plate 103. Among them, the guide plate 103 abuts against the upper end face of the bearing bladder 2 through the spring piece 106, and at the same time, the guide plate 103 is connected to the upper end face of the groove wall of the assembly groove 101 abutting against the bearing bladder 2 through the columnar spring 107;

[0029] The spring sheet can reduce the friction loss between the load-bearing bag and the guide plate. At the same time, the columnar spring can accumulate elastic potential energy when the front end of the guide plate is lifted due to the expansion of the load-bearing bag. When the drilling operation is completed and the equipment is recovered, when the pressure in the load-bearing bag is reduced, the elastic potential energy accumulated by the columnar spring can realize radial compression of the pulp bag.

[0030] Thereby achieving the effect of rapid contraction and recovery of the carrying bag.

[0031] In this embodiment, the multi-way valve 5 is connected to the outer side of the guide sleeve 1 , and a positioning cavity 4 is set on the outer side of the guide sleeve 1 corresponding to the multi-way valve 5 , and at least 1 / 3 of the multi-way valve 5 is embedded in the positioning cavity 4 .

[0032] In the specific implementation of the present invention, firstly, the guide sleeve, the bearing tube, the elastic protective cover, the multi-way valve, the positioning screws and the bearing bag constituting the present invention are assembled to obtain a finished sealing device.

[0033] During operation, the drill rod is first inserted into the guide sleeve of the sealing device and slidably connected with the inner arm of the guide sleeve, and the multi-way valve of the sealing device is connected with the external exhaust gas collection system and the boosting system; then the drilling operation is carried out, and while the drilling operation is being carried out, the sealing device is inserted into the borehole together with the drill rod, and after the sealing device reaches the set depth of the borehole, the boosting system is driven to operate, and the external medium is pressurized by the boosting system and then injected into the bearing bag through the multi-way valve, so that the grouting bag expands in volume under pressure, and after the grouting bag expands, each bearing tube is driven to open, and while it is opening, The positioning screws connected to the support tube are inserted into the wall of the borehole, thereby realizing the positioning of the equipment. At the same time, when the support tube is blocked, the elastic protective cover is also deployed synchronously, thereby realizing the preliminary blocking of the borehole to prevent the dust and gas in the borehole from overflowing from the borehole; at the same time, after the sealing device is deployed, the exhaust gas collection system is driven to operate, and the exhaust gas collection system and the multi-way valve cooperate to form a negative pressure environment in each support tube, and then the negative pressure environment inside is used to make the dust and gas in the borehole enter the support tube through the through hole of the support tube, and then drain it to the external exhaust gas collection system through the support tube, thereby completing the drilling environment purification operation;

[0034] After the drilling operation is completed, the multi-way valve can be driven to operate, so that the high-pressure medium delivered by the external booster system enters the support pipe, and the high-pressure medium is discharged into the borehole from the through hole of the support pipe, thereby achieving the purpose of using the high-pressure medium to seal the borehole.

[0035] The boosting system is any one or a combination of the air compressor system, the hydraulic station system and the grouting and plugging system.

[0036] The new device has a simple structure and is flexible and convenient to use. It can effectively meet the needs of a variety of drilling holes and drill rods. During operation, it can effectively assist in positioning the running status of the drill rod, improve the running stability of the drill rod, and effectively realize auxiliary dust reduction operations during the drilling process, and effectively collect and manage toxic and harmful gases and drilling fluids in the drilling hole, thereby effectively improving the safety and reliability of the drilling operation. In addition, after the drilling operation is completed, it can assist in the sealing of the drilling hole, thereby improving the efficiency of the drilling protection operation and the convenience of the sealing operation.
