The following is a description of the embodiments of the present invention based on its overall structure.
[0038] Example 1
[0039] like Figure 1-2 As shown, a detonating network junction box includes a junction box chassis 1 and a junction box cover 2, wherein the junction box cover 2 is detachably buckled on the junction box chassis 1 and further fixed to the junction box chassis 1 by a buckle 3. In this embodiment, the junction box chassis 1 and the junction box cover 2 are both annular, and the junction box chassis 1 and the junction box cover 2 are buckled together to form a hollow annular accommodation space for connecting and fixing the detonator pin 10 and the detonating bus 12, etc., so that a dry environment can be maintained in the detonating network junction box to avoid contact with water, thereby solving the problem of water leakage and electric leakage in the detonating network during underwater blasting construction, which leads to abnormal connection or even blind shots.
[0040] Specific, combined Figure 3-4The junction box chassis 1 is an annular structure, and the outer circle and inner circle of the annular junction box chassis 1 are respectively provided with a chassis cylindrical outer wall 19 and a chassis cylindrical inner wall 15 which are sleeved with the junction box cover 2. The outer side of the chassis cylindrical outer wall 19 is provided with a chassis buckle 3 groove, and the chassis cylindrical inner wall 15 is provided with a chassis wire port slot 4 at intervals, and the junction box chassis 1 between the chassis cylindrical outer wall 19 and the chassis cylindrical inner wall 15 is respectively provided with a cable positioning slot 6 and a wire tail clip 9 limit column 7. The chassis wire port slot 4 is arranged at intervals along the circumferential direction of the chassis cylindrical inner wall 15, and is used to fix the detonator foot line 10, the detonating busbar 12, etc. Preferably, a rubber pad layer 17 is bonded and fixed inside the chassis wire port slot 4. The rubber pad layer 17 is made of waterproof rubber and will deform and reduce its volume when squeezed. After the rubber pad layer 17 is installed, the wire port slot has an aperture smaller than the detonator leg line 10, ensuring that the wire port slot is completely blocked after the detonator leg line 10 is inserted. The rubber pad layer 17 can also reduce the force on the cable when the junction box shakes, and prevent the cable from being pulled and detached due to shaking. The cable positioning slots 6 are arranged at intervals along the outer circumference of the chassis cylindrical inner wall 15 of the annular junction box chassis 1, and correspond to the position of the chassis wire port slot 4, and are used for further fixing the detonator leg line 10, etc. The wire tail clamp 9 limit column 7 is arranged at intervals along the inner circumference of the chassis cylindrical outer wall 19, and corresponds to the position of the cable positioning slot 6. The wire tail clip 9 limiting column 7 and the cable positioning slot 6 are used to fix the wire tail clip 9 at the tail of the detonator leg line 10. When placing, first place the wire tail clip 9 in the chassis 1 of the junction box, place it on the wire tail clip 9 limiting column 7, then snap the detonator leg line 10 into the cable positioning slot 6, and then snap it into the chassis wire port slot 4.
[0041] Specific, combined Figure 5-7The wiring collection box cover plate 2 is an annular structure, and the outer circle and inner circle of the annular wiring collection box cover plate 2 are respectively provided with a cover plate cylindrical outer wall 18 and a cover plate cylindrical inner wall 14 which are sleeved with the wiring collection box cover plate 2. When the wiring collection box chassis 1 and the wiring collection box cover plate 2 are buckled together, the cover plate cylindrical outer wall 18 is located on the outer side of the chassis cylindrical outer wall 19, and the cover plate cylindrical inner wall 14 is located on the inner side of the chassis cylindrical inner wall 15. The inner and outer buckles 3 are conducive to the sealing buckling of the wiring collection box chassis 1 and the wiring collection box cover plate 2. The outer side of the cover plate cylindrical outer wall 18 is provided with a buckle 3, and when the buckle 3 is buckled in the groove of the chassis buckle 3, the wiring collection box chassis 1 and the wiring collection box cover plate 2 can be fixed. The cover plate wire port slots 5 are arranged at intervals on the cylindrical inner wall 14 of the cover plate. The positions of the cover plate wire port slots 5 correspond to the positions of the chassis wire port slots 4 inside and outside, and are used to clamp and fix the detonator leg wire 10, the detonating busbar 12, etc. Furthermore, a rubber pad layer 17 is bonded and fixed in the cover plate wire port slot 5. The rubber pad layer 17 is made of waterproof rubber and will deform and reduce its volume when squeezed. After the rubber pad layer 17 is installed, the wire port slot has an aperture smaller than the detonator leg wire 10, ensuring that the wire port slot is completely blocked after the detonator leg wire 10 is inserted. The cover plate wire port slot 5 and the chassis wire port slot 4 jointly clamp the detonator leg wire 10 and other cables, which can better prevent the cables from being pulled and detached due to shaking. Preferably, it also includes a waterproof gasket 16, which is both waterproof and has a certain elasticity. Combined with Figure 6-7 , the waterproof gasket 16 is clamped at the cover plate wire port slot 5, and the top of the waterproof gasket 16 is fixed to the cover plate cylindrical inner wall 14 or the junction box cover plate 2, and the bottom of the waterproof gasket 16 can be flipped relative to the cover plate wire port slot 5. When the cover plate wire port slot 5 is connected to the detonator leg line 10 and other cables, the waterproof gasket 16 will be lifted up and bent upward. When no cable is connected, the waterproof gasket 16 can play a sealing role. The required number of detonator leg lines 10 can be connected as needed for detonation, without the need to fill the chassis wire port slot 4 and the cover plate wire port slot 5 on the junction box, and can also ensure that the junction box maintains a dry environment to avoid contact with water, thereby expanding the application range of the junction box.
[0042] Furthermore, a cover plate wire groove 13 is provided on the outside of the junction box cover plate 2 to provide a guide for the connecting cable 11. The cable 11 connected to the construction ship is connected to the blasting network in the junction box. After the connection is completed, it is squeezed and fixed through the cable positioning slot 6 and the chassis wire port slot 4 and the cover plate wire port slot 5. After extending it from the hollowed-out area in the middle of the junction box, it is bent and placed in the cover plate wire groove 13. At the same time, the cover plate wire groove 13 also has a positioning effect, and a wire tail clip 9 is positioned under each groove.
[0043] Combination Figure 8-9, the present blasting network junction box can also be used in series. That is, when the number of connected detonators needs to be increased, another junction box is stacked below, and then the tail of the blasting busbar 12 on one of the two sides of the access cable 11 is connected to a new section of cable 11, which is extended from the line bottom plate wire slot 4 and the cover plate wire slot 5, and connected to the second junction box below, and then a new connection operation is performed. If more needs to be added, repeat the above operation. If the stacking is too high, the cable 11 connected to the end of the blasting busbar 12 in the bottom junction box can be extended, pulled out from the cover plate wire slot 13, and another layer of junction boxes can be re-stacked. That is, this device can meet the use requirements of different detonation amounts and has a wide range of uses.
[0044] Working principle and process: When using the detonating network junction box, first loosen the buckle 3 to separate it from the groove of the chassis buckle 3, remove the junction box cover 2, extend the wire tail clip 9 of the digital electronic detonator from the bottom to the top along the central hole of the junction box chassis 1, push the wire tail clip 9 to the wire tail clip 9 limit column 7, and then insert the detonator foot line 10 into the cable positioning card slot 6 and the chassis wire port card slot 4 in turn. After the wire tail clip 9 of the detonator used in the current construction is installed, or after 11 wire tail clips 9 are filled, open the wire tail clip 9 and connect the detonating bus 12 with the detonator foot line 10 in the wire tail clip 9. After the connection is completed, close the wire tail clip 9, and then connect the detonating network with the detonating cable 11. After the detonating network is connected, cover the junction box cover 2, and insert all the electronic detonator foot lines 10 into the cover plate wire port card slot 5 upward to complete the sealing of the wire port card slot. In the position where the wire tail clip 9 is not inserted, a waterproof gasket 16 is provided in the wire port buckle 3 of the cover plate. When the chassis and the cover plate are buckled, the waterproof gasket 16 will be clamped under pressure to isolate the connection between the chassis wire port slot 4 and the outside world and prevent water from entering. After closing the cover plate, buckle the buckle 3 on the cover plate into the groove of the chassis buckle 3 to achieve the protection of the blasting network in underwater blasting construction. When it is necessary to increase the number of connected detonators, stack another junction box below, and then connect the tail part of the blasting busbar 12 on one of the two sides of the access cable 11 to a new section of the cable 11, extend it from the wire port slot, connect it to the second junction box below, and then perform a new connection operation. The above is the construction process of the blasting network junction box.
[0045] In summary, the present application can keep the detonating network in a dry environment and avoid contact with water by fixing the wire tail clip 9 of the digital electronic detonator in the detonating network junction box. The junction box is arranged in a ring shape, and the wires are led from the middle. When in use, the wire tail clips 9 of multiple digital electronic detonators are evenly distributed in the junction box, and multiple detonator leg wires 10 and cables 11 are connected into a whole, and the force is dispersed, so that when the junction box is bumped and shaken by the impact of water flow, the connection of the detonating network can still be guaranteed to be stable.
