Description

Technical Field

[0001] The utility model belongs to the technical field of explosive production, and in particular relates to a safety control device for testing finished explosive products. Background Art

[0002] After the production of explosives is completed, it is necessary to test various indicators of the product, such as the detection of parameters such as detonation velocity, intensity, and detonation distance. For special supplies such as explosives, the first thing to ensure during the inspection process is safety. Therefore, the technical safety requirements for quality inspectors during inspection are very detailed, such as "operators are not allowed to bring detonating equipment to extract explosive samples... Two people must cooperate during the test, and one person is prohibited from operating alone... When conducting explosive performance tests, you must greet and count the number of people present. After confirming that all participants have entered the performance test preparation room and that there is no one in the test tower and its surroundings, power on for detonation. An audible alarm signal must be issued before the test"; this specification is very rigorous, but in the existing test process, if It is carried out in full accordance with the specifications. Because the blasting point is far away from the test tower, it is very cumbersome to check whether the various test devices are in place and whether the explosion-proof doors of the test tower are safely closed before detonation. For example, after the various test devices are in place, the relevant test personnel will gather at the blasting point and confirm by counting the number of people and reporting their work content. However, whether the explosion-proof doors of the test tower are safely closed cannot be confirmed over a long distance. If manual confirmation is performed, it will be very time-consuming and dangerous. If it is not confirmed, once the explosion-proof doors are not completely closed, the shock wave generated by the explosion will cause harm to the surrounding environment and people. Therefore, this defect must be overcome to ensure the safe and effective conduct of the test. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide a safety control device for testing finished explosives, which overcomes the defects in the prior art and can remotely monitor whether the explosion-proof door of the test tower is closed and detonate in time to ensure safe and efficient testing.

[0004] In order to solve the above technical problems, the technical solution of the utility model is:

[0005] A safety control device for testing finished explosives comprises a double-link double-control switch, wherein the double-link double-control switch is connected to a neutral line of an external power supply through an alarm, and the double-link double-control switch connected to a live line of the external power supply is also respectively connected to a detonator and a detonator for detonation; the detonator is also connected to the detonating line of the detonator through a travel switch; the travel switch is arranged on an explosion-proof door of a test tower.

[0006] Preferably, the double-gang double-control switch includes a first switch and a second switch, the first switch is provided with four terminals, the neutral line of the external power supply is connected to the first pair of terminals of the first switch through the alarm, and the terminals are also connected to the live line of the external power supply; the first end line of the detonator is connected to one leg line of the detonator through the second pair of terminals of the first switch and the second switch, and the second end line of the detonator is connected to another leg line of the detonator through the travel switch.

[0007] Preferably, the model of the double-connected double-control switch is BXK56-16, and the manufacturer is Weifang Dongxing Explosion-proof Electrical Appliance Co., Ltd.

[0008] Preferably, the external power supply is a power supply that can provide a voltage of 220 volts.

[0009] Preferably, the detonator is provided with a detection device for detecting whether the circuit is connected. The model is GTC-500, and the manufacturer is Zhongzheng Guotai (Beijing) Information Technology Co., Ltd.

[0010] Preferably, the alarm is an audible and visual alarm, model LTE-1101J, and the manufacturer is Yueqing Jindeng Electric Technology Co., Ltd.

[0011] Preferably, the travel switch is installed on the top of the door frame of the explosion-proof door of the test tower. The model is DLXK-15B, and the manufacturer is Songbei Explosion-proof Electrical Appliance Co., Ltd. The explosion-proof door of the test tower is connected when it is fully closed, and disconnected when it is not fully closed.

[0012] Preferably, the detonator is a digital electronic detonator, which is detonated by electricity.

[0013] Due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0014] The utility model realizes the remote detection of whether the explosion-proof door of the test tower is closed through the joint control of the double-link double-control switch, the alarm and the travel switch. Only when the alarm is activated and the explosion-proof door of the test tower is completely closed, can the detonation circuit be connected, and then the detonator is started to perform the explosion test; if the explosion-proof door of the test tower is not completely closed, the detonation circuit cannot be connected, and it can be observed through the detection device on the detonator, and the explosion-proof door needs to be closed manually. Through the above design, it is possible to confirm whether the explosion-proof door of the test tower is completely closed at a distance before detonation, and detonate, saving manpower and material resources, and ensuring the safety of the finished product test.

[0015] In short, the utility model overcomes the defects in the prior art, can warn and remotely monitor whether the explosion-proof door of the test tower is closed, and detonate in time to ensure the safe and efficient conduct of the test. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0020] Embodiment 1

[0021] like Figure 1 and Figure 2 As shown, the utility model is a safety control device for testing finished explosives, comprising a double-link double-control switch 1, wherein the double-link double-control switch 1 is connected to a neutral line of an external power supply 3 through an alarm 2, and the double-link double-control switch 1 connected to a live line of the external power supply 3 is also respectively connected to a detonator 4 and a detonator 5 for detonation; the detonator 5 is also connected to the detonating line of the detonator 4 through a travel switch 6; the travel switch 6 is arranged on an explosion-proof door (not shown) of a test tower 7.

[0022] When the utility model conducts finished explosive inspection, the explosion-proof door of the test tower 7 is first closed, the travel switch 6 is turned on, and then the second switch 9 and the first switch 8 set on the double-link double-control switch 1 are turned on in sequence, and the alarm 2 is activated to warn; at the same time, the explosion-proof door of the test tower 7 is observed by the detonator 5 to see whether it is completely closed. If it is not completely closed, the travel switch 6 is not closed, the detonation cannot be carried out, and it needs to be closed manually; if the explosion-proof door is completely closed, the detonator 5 can be detonated normally, and the detonation can be carried out by the detonator 5. Through the above control, it can be ensured that whether the explosion-proof door is safely closed can be remotely detected during the test, and an alarm can be issued; it prevents waste of manpower and damage to the surrounding environment caused by the explosion impact caused by the incomplete closure of the explosion-proof door.
