DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment 1

[0029] See also Figure 1-3 The utility model is a blasting hole plugging device for complex environments, including a plugging tube 1, and a conical groove 101 for the conical column 2 to penetrate therein, and a fixing plate 3 for installing an assembly component 4 is arranged on the outside of one side of the shaft end.

[0030] Specifically, a conical groove 101 is opened at the inner center of the plugging cylinder 1, and a side groove 102 is opened on the outer side of the conical groove 101 and the inside of the plugging cylinder 1, and a side hole 103 is also opened on the outer wall of the side groove 102, wherein the plugging cylinder 1 is threadedly connected to the conical column 2 through the conical groove 101, and a turntable 201 for hand-held rotation of the conical column 2 is also installed at the outer axial end of the conical column 2, and the fixed disk 3 is connected to the outer wall of the plugging cylinder 1 through the mounting column 301 on the rear side wall.

[0031] Furthermore, there are four side grooves 102 in total, and the four side grooves 102 are arranged in a ring array structure. A plurality of side holes 103 are opened on one side groove 102, and the side holes 103 are arranged in an equidistant structure. Specific embodiment 2

[0033] See also Figure 4 On the basis of the specific embodiment 1, an assembly component 4 is also provided. The assembly component 4 is fixed to the outer wall of the fixed disk 3 by the clamping plate 401, and the elastic member 402 therein can extend outward when the positioning plate 403 is subjected to traction, so that the positioning plate 403 on the shaft end can be stretched to a more outer area and fixed by rotating the stud 404.

[0034] Specifically, the assembly component 4 includes a clamping plate 401, and an elastic member 402 threadedly connected to a screw hole 401a on its outer wall. The clamping plate 401 is connected to a positioning plate 403 via the elastic member 402, and the positioning plate 403 is also provided with a screw groove for threadedly connecting a rotating stud 404, and the rear end of the rotating stud 404 is abutted against the outer wall of the blasting hole via an abutment spring 405.

[0035] Furthermore, there are four assembly components 4 in total, and the four assembly components 4 are arranged in a ring array structure. The elastic member 402 includes a hollow column 402a, a connecting spring 402b and a solid column 402c, and one end of the solid column 402c is inserted into the interior of the hollow column 402a, and the end of the solid column 402c located inside the hollow column 402a is connected to the inner wall of the hollow column 402a through the connecting spring 402b.

[0036] The operation process of this embodiment is: hold the positioning plate 403 and stretch it outward until the positioning plate 403 moves to a relatively hard position suitable for the rotating stud 404 to be inserted and fixed, then stop stretching the positioning plate 403, and then insert the rotating stud 404 into the positioning plate 403, and put the abutment spring 405 on a section between the rotating stud 404 and the blasting hole, and then rotate the rotating stud 404 to insert the rotating stud 404 into the ground in the area around the blasting hole, completing the installation of one assembly component 4, and then install the other three assembly components 4 in sequence. Specific embodiment three

[0038] See also Figure 5 On the basis of the specific embodiment 1 and the specific embodiment 2, a blocking component 5 is further provided. The blocking component 5 can be inserted into the blocking tube 1 through the sliding column 503, and the buffer spring 503 on the rear side thereof can naturally contract or extend when the abutment plate 501 rubs against the inner wall of the blasting hole, and the abutment column 504 on the rear side thereof can extend outward against the sliding column 503 and the abutment plate 501 and abut against the inner wall of the blasting hole when receiving the extrusion force of the conical column 2.

[0039] Specifically, the blocking component 5 includes an abutment plate 501 and a rubber pad 502 bonded to its outer wall, and a sliding column 503 is detachably installed on the rear side of the abutment plate 501, and the end of the sliding column 503 is connected to the abutment column 504 through a buffer spring 503a, and a plate groove 501a for accommodating a connecting plate 505 is also provided on the outer wall of the abutment plate 501, and the connecting plate 505 is connected to the abutment plate 501 through an elastic rod 505a.

[0040] Furthermore, a plurality of groups of blocking components 5 are arranged at equal intervals, and each group of blocking components 5 is provided with four blocking components 5, and the four blocking components 5 are arranged in a ring array, and the four abutment plates 501 in a group of blocking components 5 are interconnected by elastic rods 505a and connecting plates 505. At the same time, the sliding column 503 is inserted into the side hole 103 opened on the blocking cylinder 1, and the buffer spring 503a on the end of the sliding column 503 is arranged in the side groove 102, and the abutment column 504 extends through the side groove 102 into the conical groove 101.

[0041] The operation process of this embodiment is as follows: the conical column 2 slowly penetrates into the conical groove 101 in the plugging cylinder 1. Because the conical column 2 is conical, the plugging assembly 5 on the outer wall of the plugging cylinder 1 can be gradually pushed out of the plugging cylinder 1 in sequence. While being pushed out, the outer wall of the conical column 2 contacts the end of the abutment column 504, causing it to slowly move outward and press against the outer wall of the buffer spring 503a and the sliding column 503, and then the abutment plate 501 also moves outward accordingly, and finally the abutment plate 501 passes through the rubber pad 5 02 abuts against the inner wall of the blasting hole. At the same time, as the abutment plate 501 gradually expands outward, the elastic rod 505a between the abutment plates 501 is also stretched, so that the two ends of the connecting plate 505 on its axial end gradually slide out of the plate groove 501a, and the connecting plate 505 also contacts the inner wall of the blasting hole. Because the abutment plate 501 has abutted against the inner wall of the blasting hole, the conical column 2 is unable to rotate due to resistance, which completes the fixing of the device in the blasting hole to achieve the effect of blocking the blasting hole.
