Description

Technical Field

[0001] This utility model relates to the field of electronic detonator detection and protection technology, specifically to a single-shot detection and protection device for electronic detonators. Background Technology

[0002] Before blasting operations, electronic detonators must undergo quality testing to ensure their accuracy. During construction, if a detonator misfires, its energization must be checked to preliminarily determine the cause of the misfire. Single-shot testing of electronic detonators is extremely important, as safety is paramount.

[0003] The pressure relief holes of existing detonator detection and protection devices are usually set horizontally, and fragments from a single detonator explosion can easily fly out of the pressure relief hole and injure people. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a single-shot detection and protection device for electronic detonators, addressing the above-mentioned shortcomings.

[0005] To solve the above technical problems, the present invention adopts the following technical solution:

[0006] A single-shot detection and protection device for electronic detonators includes a housing, a detonator placement port, a detonator placement platform, a first pressure relief hole, and a second pressure relief hole. The detonator placement platform, with its central portion protruding upwards, is horizontally suspended inside the housing. A detonator placement groove is formed in the center of the platform. The platform is fixedly connected to the inner wall of the housing. Communicating holes are formed at the four corners of the housing cavity. A detonator placement port corresponding to the platform is formed at the upper front end of the housing. A sealing plate, capable of opening in one direction, is hinged to the inner side of the housing at the detonator placement port. The sealing plate can open or close the detonator placement port. Horizontal supports are provided at each of the four corners of the housing cavity above the detonator placement port. The box has square right-angled flanges, on which pressure relief plates are horizontally arranged. A buffer assembly is provided between the top of the pressure relief plate and the top wall of the inner cavity of the box. First pressure relief holes are opened on the left, right and rear sides of the box, located outside the pressure relief plates. Second pressure relief holes are opened on the left and right sides of the box, located below the detonator placement platform. When the pressure relief plate is stationary, it can block the first pressure relief hole at the top of the box. After the detonator explodes, it can move upward under the upward push of the high-speed explosion gas, thereby opening the first pressure relief hole, so that the high-speed explosion gas can be discharged from the first pressure relief hole. When the pressure of the explosion gas decreases, the pressure relief plate can be reset by the buffer assembly and gravity, so that the remaining gas can be discharged from the second pressure relief hole.

[0007] Furthermore, a groove for placing the electronic detonator lead is provided at the detonator placement port. The groove is an inverted L-shaped groove and the lower end of the vertical section extends to the bottom of the sealing plate.

[0008] Furthermore, the first pressure relief hole is an inverted L-shaped hole, with the output end of the first pressure relief hole facing downwards.

[0009] Furthermore, the second pressure relief hole is an inverted V-shaped hole, and the output end of the second pressure relief hole is tilted downward.

[0010] Furthermore, a cleaning port is provided on the front side of the housing, located below the detonator placement platform. A sealed door is hinged to the cleaning port, which is used to open or close the cleaning port.

[0011] Furthermore, the enclosure material is fiber cement composite steel plate, and the enclosure wall thickness is 15-20mm.

[0012] Furthermore, the buffer assembly includes multiple springs and buffer filler, with the multiple springs arranged in a uniform vertical array and the gaps between adjacent springs filled with buffer filler.

[0013] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages:

[0014] This invention, by setting a first pressure relief hole and a second pressure relief hole, with the output end of the first pressure relief hole facing downwards and the output end of the second pressure relief hole tilted downwards, changes the discharge direction of the high-speed explosive gas flow, preventing fragments from flying horizontally out of the pressure relief hole and injuring people during a single detonator explosion. When the detonator explodes, the high-speed explosive gas flow spreads upwards, pushing the pressure relief plate and opening the first pressure relief hole, allowing the gas flow to be discharged first. After the pressure decreases, the pressure relief plate returns to its original position, and the remaining gas flow is discharged through the second pressure relief hole, effectively guiding the gas flow and ensuring testing safety. An inverted L-shaped groove is provided at the detonator placement port for easy placement of the electronic detonator lead; a cleaning port with a hinged airtight door is provided on the front side of the box for convenient periodic cleaning of detonator debris inside the box. The box body is made of fiber cement composite steel plate with a wall thickness of 15-20mm, improving the strength and explosion resistance of the device and further ensuring the safety of the testing process.

[0015] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model.

[0025] like Figure 1-5As shown, a single-shot detection and protection device for electronic detonators includes a housing 1, a detonator placement port 2, a detonator placement platform 3, a first pressure relief hole 4, and a second pressure relief hole 5. The housing 1 has a horizontally suspended detonator placement platform 3 with an upward-protruding center. A detonator placement groove 6 is formed in the center of the detonator placement platform 3. The detonator placement platform 3 is fixedly connected to the inner wall of the housing 1. The detonator placement platform 3 has connecting holes 7 at the four corners of the inner cavity of the housing 1. The upper front end of the housing 1 has a detonator placement port 2 corresponding to the detonator placement platform 3. A sealing plate 8, which can open in one direction, is hinged to the inner side of the housing 1 at the detonator placement port 2. The sealing plate 8 can open or close the detonator placement port 2. Horizontal sealing plates are provided at the four corners of the inner cavity of the housing 1 above the detonator placement port 2. The box has a right-angled flange 9, and a pressure relief plate 10 is horizontally arranged on the multiple right-angled flanges 9. A buffer assembly 11 is arranged between the top of the pressure relief plate 10 and the top wall of the inner cavity of the box 1. The box 1 has a first pressure relief hole 4 on the left, right and rear sides, located outside the pressure relief plate 10. The box 1 also has a second pressure relief hole 5 on the left and right sides, located below the detonator placement platform 3. When the pressure relief plate 10 is stationary, it can block the first pressure relief hole 4 at the top of the box 1. After the detonator explodes, it can move upward under the upward push of the high-speed explosion airflow, thereby opening the first pressure relief hole 4, so that the high-speed explosion airflow can be discharged from the first pressure relief hole 4. When the pressure of the explosion airflow decreases, the pressure relief plate 10 can be reset by the buffer assembly 11 and gravity, so that the remaining airflow can be discharged from the second pressure relief hole 5.

[0026] In one embodiment, a groove 12 for placing electronic detonator leads is provided at the detonator placement port 2. The groove 12 is an inverted L-shaped groove and the lower end of the vertical section extends to the bottom of the sealing plate 8.

[0027] In one embodiment, the first pressure relief hole 4 is an inverted L-shaped hole, with the output end of the first pressure relief hole 4 facing downwards.

[0028] In one embodiment, the second pressure relief hole 5 is an inverted V-shaped hole, and the output end of the second pressure relief hole 5 is inclined downward.

[0029] In one embodiment, a cleaning port is provided on the front side of the housing 1, located below the detonator placement platform 3. A sealed door 13 is hinged to the cleaning port, and the sealed door 13 is used to open or close the cleaning port.

[0030] In one embodiment, the housing 1 is made of fiber cement composite steel plate, and the wall thickness of the housing 1 is 15-20mm.

[0031] In one embodiment, the buffer assembly 11 includes a plurality of springs 1101 and a buffer filler 1102. The plurality of springs 1101 are arranged in a uniform vertical array, and the gap between two adjacent springs 1101 is filled with the buffer filler 1102.

[0032] In this invention, the buffer filler 1102 is made of pearl cotton.

[0033] The working process of this utility model is as follows: Open the inwardly opening one-way sealing plate 8 at the detonator placement port 2 on the front side of the housing 1, place the electronic detonator in the detonator placement slot 6 of the detonator placement platform 3, and simultaneously place the electronic detonator lead wire into the inverted L-shaped wire groove 12 at the detonator placement port 2. The lower end of the vertical section of the wire groove 12 extends to below the sealing plate 8. After placement, the sealing plate 8 closes automatically or manually. Connect the electronic detonator lead wire to the external detonator through the wire groove 12 to prepare for subsequent testing. Start the detonator to perform a charge and discharge test on the electronic detonator. If the electronic detonator is normal during this process, the testing process is completed.

[0034] If the electronic detonator explodes:

[0035] The high-speed explosive gas flow spreads upward, pushing the pressure relief plates 10 located on multiple right-angle flanges 9, compressing the buffer assembly 11 between the top of the pressure relief plates 10 and the top wall of the inner cavity of the housing 1. After the pressure relief plates 10 are pushed, the output ends of the inverted L-shaped first pressure relief holes 4 on the left, right, and rear sides of the housing 1, located outside the pressure relief plates 10, are opened downwards, allowing the high-speed explosive gas flow to escape from the first pressure relief holes 4, preventing fragments from flying horizontally and injuring people. When the pressure of the explosive gas flow decreases, the pressure relief plates 10 return to their original position under the elastic force of the buffer assembly 11 and their own gravity. The remaining gas flow is discharged downwards at an angle from the output ends of the inverted V-shaped second pressure relief holes 5 on the left and right sides of the housing 1, located below the detonator placement platform 3. After the test is completed, the sealed door 13 at the cleaning port on the front side of the housing 1, located below the detonator placement platform 3, can be opened to periodically clean the detonator debris inside the housing 1.
