Description

Technical Field

[0001] The utility model relates to the technical field of electronic detonator anti-interference, in particular to an electronic detonator anti-interference shielding structure. Background Art

[0002] Electronic detonators, also known as digital electronic detonators, digital detonators or industrial digital electronic detonators, are electronic detonators that use electronic control modules to control the initiation process. The anti-interference ability of electronic detonators is an important aspect in their design and application.

[0003] Existing electronic detonators may be affected by mechanical vibrations and vibrations generated by the explosion of other detonators. Therefore, anti-vibration design is needed to improve their reliability. The electronic control module inside the existing electronic detonator is usually directly installed inside the electronic detonator and fixed in contact with its inner wall. The vibration and mechanical vibration generated by the explosion can easily be transmitted to the electronic control module, causing damage to the electronic control module, which will lead to failure of the electronic detonator to detonate, and the anti-vibration effect is poor. Utility Model Content

[0004] The purpose of the utility model is to provide an anti-interference shielding structure for an electronic detonator to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] An anti-interference shielding structure for an electronic detonator includes an electronic detonator, one end of which is fixedly provided with an anti-vibration component, the anti-vibration component including a shielding shell fixedly mounted on one end of the electronic detonator, a No. 1 rubber sleeve fixedly sleeved on the outside of the shielding shell, noise reduction cotton fixedly mounted inside the shielding shell, a support component fixedly mounted inside the noise reduction cotton, the support component including two rubber storage tubes fixedly mounted on the inner surface of the noise reduction cotton, a rubber push rod slidably connected inside the rubber storage tube.

[0007] Furthermore, an explosive is fixedly provided at one end of the electronic detonator, a fire transfer hole is fixedly provided at one side of the explosive, and a delay charge is fixedly provided at one side of the fire transfer hole.

[0008] The invention further comprises: a No. 2 rubber sleeve is fixedly provided on one end of the outer surface of the electronic detonator.

[0009] Furthermore, support rings are symmetrically fixedly installed at both ends of the outer surface of the noise reduction cotton, a plurality of support blocks are fixedly installed at equal angles on the outer surface of the support ring, and one end of the support block is fixedly connected to the shielding shell.

[0010] Furthermore, an air injection port is fixedly embedded and installed at the lower end of the outer surface of the rubber storage tube, and a sealing cover is screwed and connected to the outer side of the air injection port.

[0011] Furthermore, the upper ends of the two rubber push rods are fixedly mounted with connecting plates, and both ends of the two connecting plates are symmetrically fixedly connected with rails.

[0012] Preferably, an electronic control module is movably plugged into the two rails, and a wire at one end of the electronic control module is fixedly passed through the noise reduction cotton, the shielding shell and the surface of one end of the No. 1 rubber sleeve.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The explosion vibration transmitted to the electronic detonator is initially reduced by the No. 2 rubber sleeve and the No. 1 rubber sleeve. Then the vibration of the shielding shell is transmitted to the support ring through the support block, reducing the area of vibration transmission. The weakened vibration is again transmitted to the noise reduction cotton. The vibration is further weakened by the structural characteristics of the noise reduction cotton itself. At the same time, the noise transmission is reduced by the noise reduction cotton. Thus, by reducing the transmission of vibration multiple times, the noise generated by the explosion is reduced, ensuring that the signal received by the electronic detonator is clear and accurate.

[0015] 2. The vibration of the noise reduction cotton is transmitted to the rubber storage tube and the rubber push rod, and is further reduced, thereby further reducing the vibration transmitted to the electronic control module. By further reducing the vibration transmitted to the electronic control module, the vibration is prevented from being transmitted to the electronic control module and causing damage to the electronic control module, thereby improving the anti-vibration effect and reducing the impact of vibration on the initiation of the electronic detonator. Compressed air is injected into the rubber storage tube through the air injection port so that the rubber push rod is always extended. Under more intense vibration and shaking, the electronic control module can move slightly up and down with the rubber push rod, and then reset under the action of the compressed gas, thereby further improving the anti-vibration effect of the electronic control module.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on 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.

[0023] See also Figures 1 to 5 In an embodiment of the utility model, an anti-interference shielding structure of an electronic detonator includes an electronic detonator 1, wherein an explosive 101 is fixedly provided at one end of the electronic detonator 1, a fire transmission hole 102 is fixedly provided on one side of the explosive 101 inside the electronic detonator 1, a delay agent 103 is fixedly provided on one side of the fire transmission hole 102 inside the electronic detonator 1, an anti-vibration component 2 is fixedly provided at one end of the electronic detonator 1, the anti-vibration component 2 includes a shielding shell 201 fixedly mounted on one end of the electronic detonator 1, a No. 1 rubber sleeve 202 is fixedly sleeved on the outer side of the shielding shell 201, a noise reduction cotton 206 is fixedly mounted inside the shielding shell 201, a support component 3 is fixedly provided inside the noise reduction cotton 206, the support component 3 includes two rubber storage tubes 301 fixedly mounted on the inner surface of the noise reduction cotton 206, and a rubber push rod 302 is slidably connected to the inside of the rubber storage tube 301.

[0024] Specifically, the anti-vibration component 2 and the support component 3 reduce the vibration transmitted to the electronic control module 104 from the outside, and at the same time reduce the noise transmitted to the electronic control module 104 through the noise reduction cotton 206, thereby improving the anti-vibration and anti-noise effects of the electronic detonator 1, making it easier for the electronic control module 104 to ignite the delay charge 103 so that the explosive 101 can be detonated normally.

[0025] Example 1

[0026] like Figure 2-4 As shown, in this embodiment, a No. 2 rubber sleeve 203 is fixedly provided at one end of the outer surface of the electronic detonator 1; support rings 204 are symmetrically fixedly installed at both ends of the outer surface of the noise reduction cotton 206, and a plurality of support blocks 205 are fixedly installed at equal angles on the outer surface of the support ring 204, and one end of the support block 205 is fixedly connected to the shielding shell 201.

[0027] In this embodiment, the No. 2 rubber sleeve 203 and the No. 1 rubber sleeve 202 prevent the electronic detonator 1 from directly contacting the blasting hole wall, preliminarily reducing the explosion vibration transmitted to the electronic detonator 1, and the remaining vibration is transmitted to the shielding shell 201 through the two, and then the vibration of the shielding shell 201 is transmitted to the support ring 204 through the support block 205, reducing the area of vibration transmission, and the vibration that is weakened again is transmitted to the noise reduction cotton 206, and the vibration is further weakened by the structural characteristics of the noise reduction cotton 206 itself. At the same time, the noise transmission is reduced by the noise reduction cotton 206, thereby reducing the transmission of vibration multiple times and the noise generated by the explosion, thereby ensuring that the signal received by the electronic detonator 1 is clear and accurate.

[0028] like Figure 5 As shown, in this embodiment, an air injection port 303 is fixedly embedded at the lower end of the outer surface of the rubber storage tube 301, and a sealing cover 304 is screwed on the outer side of the air injection port 303; a connecting plate 305 is fixedly installed on the upper ends of the two rubber push rods 302, and the two ends of the two connecting plates 305 are symmetrically fixedly connected with a rail 306; the electronic control module 104 is movably plugged into the inside of the two rails 306, and the wire at one end of the electronic control module 104 is fixedly passed through the noise reduction cotton 206, the shielding shell 201 and the surface of one end of the No. 1 rubber sleeve 202.

[0029] During specific implementation, the vibration at the noise reduction cotton 206 is transmitted to the rubber storage tube 301 and the rubber push rod 302, and is further reduced, thereby reducing the vibration transmitted to the electronic control module 104 again. By reducing the vibration transmitted to the electronic control module 104 again, the vibration is prevented from being transmitted to the electronic control module 104 and causing damage to it, thereby improving the anti-vibration effect and reducing the impact of vibration on the detonation of the electronic detonator 1. Compressed air is injected into the rubber storage tube 301 through the air injection port 303, so that the rubber push rod 302 is always extended, and under relatively severe vibration and shaking, the electronic control module 104 can move slightly up and down with the rubber push rod 302, and then reset under the action of the compressed gas, thereby further improving the anti-vibration effect of the electronic control module 104.

[0030] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
