[0021] In order to clearly and completely describe the purpose and technical solution of the present invention and make its advantages more clearly understood, the following is a further detailed description of the embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only part of the embodiments of the present invention, not all of them, and are only used to explain the embodiments of the present invention and are not intended to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1: Please refer to Figures 1 to 6 The utility model provides a technical solution: a shaped charge blasting device, comprising: a cover 1, a reserved hole 2 is provided on the surface of the cover 1, a game threading groove 3 and a detonator leg line storage groove 4 are provided on the surface of the reserved hole 2, the reserved hole 2, the threading groove 3 and the detonator leg line storage groove 4 are interconnected, and a moisture-proof cover 5 is movably inserted in the reserved hole 2, the threading groove 3 and the detonator leg line storage groove 4.

[0023] The shaped charge blasting device has the following steps: after the detonator is arranged inside the charge tube, the detonator leg wire is passed through the reserved hole 2 opened on the surface of the cover 1, and then the reserved hole 2 is introduced into the detonator leg wire receiving groove 4 through the threading groove 3. After the detonator leg wire receiving groove 4 is received, the moisture-proof cover 5 is covered on the reserved hole 2, the threading groove 3 and the detonator leg wire receiving groove 4, thereby sealing the reserved hole 2, the threading groove 3 and the detonator leg wire receiving groove 4, providing a closed environment for the detonator lead, thereby achieving the moisture-proof function.

[0024] Example 2: On the basis of Example 1, in order to limit the moisture-proof cover 5 to the appropriate position in the reserved hole 2, the wire threading groove 3 and the detonator leg wire storage groove 4, the detonator leg wire storage groove 4 is a rectangular groove structure, and a supporting ring 6 is fixed in the detonator leg wire storage groove 4. The supporting ring 6 is a "U"-shaped plate structure. The outer ring side length of the supporting ring 6 is equal to the side length of the inner wall of the detonator leg wire storage groove 4. The bottom end of the moisture-proof cover 5 is against the top surface of the supporting ring 6. An elastic ball 11 is fixed on the inner wall of the detonator leg wire storage groove 4. A card slot 10 is opened on the side wall of the moisture-proof cover 5, and the elastic ball 11 is movably inserted in the card slot 10.

[0025] After the moisture-proof cover 5 is inserted into the reserved hole 2, the wire threading groove 3 and the detonator leg wire storage groove 4, the supporting ring 6 limits the minimum height of the moisture-proof cover 5 to prevent the moisture-proof cover 5 from being inserted too deeply and squeezing the detonator leg wire and breaking the detonator leg wire. At the same time, the elastic ball 11 is inserted into the card slot 10, and the elastic ball 11 generates an extrusion force on the inner wall of the card slot 10, thereby limiting the moisture-proof cover 5 in the reserved hole 2, the wire threading groove 3 and the moisture-proof cover 5. Moreover, because the elastic ball 11 is elastic, when the moisture-proof cover 5 is pulled outward with force, it will not be completely unable to be pulled out.

[0026] Example 3: On the basis of Example 2, in order to prevent moist air from penetrating through the gaps between the moisture-proof cover 5 and the reserved hole 2, the wire threading groove 3, and the detonator leg wire storage groove 4, a sealing groove 7 is provided on the side wall of the moisture-proof cover 5. The sealing groove 7 is an annular groove body, and a sealing ring 8 is fixed in the sealing groove 7. One end of the sealing ring 8 extends out of the sealing groove 7 and rests on the inner wall surface of the reserved hole 2, the wire threading groove 3, and the detonator leg wire storage groove 4.

[0027] The sealing groove 7 is opened around the side wall of the moisture-proof cover 5. The sealing ring 8 fixed in the sealing groove 7 blocks the gaps between the moisture-proof cover 5 and the reserved holes 2, the wire threading groove 3, and the detonator leg wire storage groove 4, thereby preventing humid air from penetrating through the gaps between the moisture-proof cover 5 and the reserved holes 2, the wire threading groove 3, and the detonator leg wire storage groove 4.

[0028] Example 4: Based on Example 3, in order to prevent the detonator leg line from running around in the detonator leg line storage groove 4 and retracting into the reserved hole 2, a rubber pad 9 is fixed to the bottom end of the moisture-proof cover 5. The rubber pad 9 is a rectangular sheet structure, and the side length of the rubber pad 9 is equal to the side length of the inner ring of the supporting ring 6.

[0029] A rubber pad 9 is provided at the bottom end of the moisture-proof cover 5. The rubber pad 9 is elastic and can press the detonator leg wire into the detonator leg wire receiving groove 4 to prevent the detonator leg wire from slipping back into the reserved hole 2 and also prevent the detonator lead wire from being broken.

[0030] Embodiment 5: Based on embodiment 4, in order to facilitate pulling out the moisture-proof cover 5 , a handle 12 is fixed to the top end of the moisture-proof cover 5 .

[0031] When it is necessary to pull the moisture-proof cover 5 out of the reserved hole 2, the wire threading groove 3 and the detonator leg wire storage groove 4, just pinch the handle 12 and pull it outward to take the moisture-proof cover 5 out of the reserved hole 2, the wire threading groove 3 and the detonator leg wire storage groove 4.

[0032] In actual use, after the detonator is placed inside the charge tube, the detonator leg wire is passed through the reserved hole 2 opened on the surface of the cover 1, and then the reserved hole 2 is introduced into the detonator leg wire storage groove 4 through the threading groove 3. After the detonator leg wire storage groove 4 is stored, the moisture-proof cover 5 is covered on the reserved hole 2, the threading groove 3 and the detonator leg wire storage groove 4 to seal the reserved hole 2, the threading groove 3 and the detonator leg wire storage groove 4, providing a closed environment for the detonator lead , thereby achieving the moisture-proof function; after the moisture-proof cover 5 is inserted into the reserved hole 2, the threading groove 3 and the detonator leg wire storage groove 4, the supporting ring 6 limits the minimum height of the moisture-proof cover 5 to prevent the moisture-proof cover 5 from being inserted too deep and squeezing the detonator leg wire and breaking the detonator leg wire. At the same time, the elastic ball 11 is inserted into the card slot 10, and the elastic ball 11 generates an extrusion force on the inner wall of the card slot 10, thereby limiting the moisture-proof cover 5 in the reserved hole 2, the threading groove 3 and the moisture-proof cover 5, and And because the elastic ball 11 is elastic, the moisture-proof cover 5 will not be completely unable to be pulled out when the moisture-proof cover 5 is pulled outward with force; the sealing groove 7 is opened around the side wall of the moisture-proof cover 5, and the sealing ring 8 fixed in the sealing groove 7 blocks the gaps between the moisture-proof cover 5 and the reserved holes 2, the threading groove 3, and the detonator leg wire storage groove 4, thereby preventing moist air from penetrating through the gaps between the moisture-proof cover 5 and the reserved holes 2, the threading groove 3, and the detonator leg wire storage groove 4 ; A rubber pad 9 is provided at the bottom end of the moisture-proof cover 5. The rubber pad 9 is elastic, that is, it can press the detonator leg wire into the detonator leg wire receiving groove 4 to prevent the detonator leg wire from running back into the reserved hole 2, and it can also prevent the detonator lead from being crushed; when it is necessary to pull the moisture-proof cover 5 out of the reserved hole 2, the wire threading groove 3 and the detonator leg wire receiving groove 4, just pinch the handle 12 and pull it outwards to take the moisture-proof cover 5 out of the reserved hole 2, the wire threading groove 3 and the detonator leg wire receiving groove 4.
