Description

Technical Field

[0001] This utility model belongs to the field of explosive ordnance disposal technology, specifically relating to an intelligent liquid nitrogen disposal platform. Background Technology

[0002] The bomb disposal work of public security special police mainly includes two aspects: searching for explosives and disposing of explosives. Searching for explosives refers to locating and locating potential explosives in a specific area using specialized equipment and methods. Disposing of explosives involves taking safe and effective measures to dismantle or destroy the explosives after they have been located, in order to ensure the safety of people's lives and property. There are many ways to dispose of explosives, one of which is to use the cryogenic properties of liquid nitrogen.

[0003] In current bomb disposal procedures, the work in the bomb disposal core area often relies on direct manual operation. This step significantly increases the risk of the operation, resulting in a relatively low overall safety level for the bomb disposal process. Because the bomb disposal core area deals with highly dangerous explosives, direct manual intervention not only tests the professional skills and psychological resilience of the bomb disposal personnel, but also inevitably increases the possibility of errors or dangers caused by human factors. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide an intelligent liquid nitrogen disposal operation platform to solve the problem that the work in the core area of ​​explosive ordnance disposal often relies on direct manual operation.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] The intelligent liquid nitrogen disposal platform includes:

[0007] Bomb disposal robot;

[0008] The bomb disposal robot is equipped with a mechanical arm on one side of its top. A clamping device is installed at the end of the mechanical arm away from the bomb disposal robot. A connecting rod is movably installed at one end of the bomb disposal robot. A processing structure is movably installed at the end of the connecting rod away from the bomb disposal robot. A hose is installed at one end of the processing structure. A pressurized firing probe is installed at the end of the hose away from the processing structure.

[0009] The processing structure includes a trolley, connecting blocks, limiting arc plates, a self-pressurizing liquid nitrogen tank, and a discharge structure. There are two connecting blocks and two limiting arc plates, and both connecting blocks are fixedly connected to one end of the trolley. Both limiting arc plates are fixedly connected to one side of the top of the trolley. The self-pressurizing liquid nitrogen tank is movably inserted between the two limiting arc plates. The discharge structure is installed at the top of the self-pressurizing liquid nitrogen tank. The connecting blocks are movably installed at one end of the connecting rod.

[0010] Preferably, a detection device is installed on one side of the top of the bomb disposal robot, and an antenna is installed on the other side of the top of the bomb disposal robot.

[0011] Preferably, the discharge structure includes a discharge head, a first connecting pipe, a pressure monitor, a pressure gauge, a second connecting pipe, a valve, a bend, and a cryogenic solenoid valve. Two first connecting pipes and two second connecting pipes are provided, and both are installed on the outer surface of the discharge head. The pressure monitor is installed at one end of one of the first connecting pipes away from the discharge head. The pressure gauge is installed at one end of the pressure monitor. Three valves are provided, and each valve is installed at one end of one of the two second connecting pipes and one of the valves. The bend is installed between the top of the self-pressurizing liquid nitrogen tank and one of the valves. The cryogenic solenoid valve is installed at one end of the other valve. The cryogenic solenoid valve is mounted together with the pressurized firing probe.

[0012] Preferably, the cryogenic solenoid valve includes a valve seat, a thermostatic rod, a junction box, and a discharge pipe.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] (1) By setting up a processing structure, connecting rods and a bomb disposal robot, the bomb disposal robot can be moved by remote control. The connecting rods can be used to pull the cart to move, thereby moving the self-pressurized liquid nitrogen tank together. When the bomb disposal robot and its self-pressurized liquid nitrogen tank move to the core area of ​​the explosive, the ignition circuit of the bomb disposal robot can be used to control the opening of the cryogenic solenoid valve. The advantages of remote control can be fully utilized, and combined with the technical characteristics of the liquid nitrogen tank, the safety and efficiency of the explosive site disposal operation can be improved by realizing remote unmanned operation in the core area.

[0017] (2) By setting up a robotic arm, clamping equipment, pressurized firing probe, hose, valve seat, thermostatic rod and junction box, the discharge structure introduces the cryogenic liquid nitrogen in the pressurized liquid nitrogen tank into the hose through the cryogenic solenoid valve.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1:

[0025] Please see Figure 1 - Figure 4 As shown, the intelligent liquid nitrogen disposal platform includes:

[0026] Bomb disposal robot 1;

[0027] A mechanical arm 2 is provided on one side of the top of the bomb disposal robot 1. A clamping device 3 is installed at the end of the mechanical arm 2 away from the bomb disposal robot 1. A connecting rod 6 is movably installed at one end of the bomb disposal robot 1. A processing structure 7 is movably installed at the end of the connecting rod 6 away from the bomb disposal robot 1. A hose 8 is installed at one end of the processing structure 7. A pressurized firing probe 9 is installed at the end of the hose 8 away from the processing structure 7.

[0028] The processing structure 7 includes a trolley 71, a connecting block 72, a limiting arc plate 73, a self-pressurizing liquid nitrogen tank 74, and a discharge structure 75. There are two connecting blocks 72 and two limiting arc plates 73. The two connecting blocks 72 are fixedly connected to one end of the trolley 71, and the two limiting arc plates 73 are fixedly connected to one side of the top of the trolley 71. The self-pressurizing liquid nitrogen tank 74 is movably inserted between the two limiting arc plates 73. The discharge structure 75 is installed on the top of the self-pressurizing liquid nitrogen tank 74. The connecting blocks 72 are movably installed on one end of the connecting rod 6.

[0029] The discharge structure 75 includes a discharge head 751, a first connecting pipe 752, a pressure monitor 753, a pressure gauge 754, a second connecting pipe 755, a valve 756, a bend 757, and a cryogenic solenoid valve 758. There are two first connecting pipes 752 and two second connecting pipes 755, and both first connecting pipes 752 and second connecting pipes 755 are installed on the outer surface of the discharge head 751. The pressure monitor 753 is installed at the end of one of the first connecting pipes 752 away from the discharge head 751. The pressure gauge 754 is installed at one end of the pressure monitor 753. There are three valves 756, and the three valves 756 are respectively installed at one end of the two second connecting pipes 755 and one of the valves 756. The bend 757 is installed between the top of the self-pressurized liquid nitrogen tank 74 and one of the valves 756. The cryogenic solenoid valve 758 is installed at one end of the other valve 756. The cryogenic solenoid valve 758 is installed together with the pressurized firing probe 9.

[0030] A detection device 4 is installed on one side of the top of the bomb disposal robot 1, and an antenna 5 is installed on the other side of the top of the bomb disposal robot 1.

[0031] As can be seen from the above, after determining the location of the explosion core area, the bomb disposal robot 1 is controlled to move. When the bomb disposal robot 1 moves, it pulls the pallet 71 to move through the connecting rod 6. The pallet 71 drives the self-pressurized liquid nitrogen tank 74 to move through the limiting arc plate 73 fixedly connected to it, thereby enabling the device to achieve unmanned operation in the explosion core area and greatly improving personnel safety.

[0032] Example 2:

[0033] refer to Figure 4 As shown, the cryogenic solenoid valve 758 includes a valve seat 81, a thermostatic rod 82, a junction box 83, and a discharge pipe 84. The thermostatic rod 82 is installed on the top of the valve seat 81, the junction box 83 is installed on the outer surface of one end of the thermostatic rod 82, the discharge pipe 84 is installed on one end of the valve seat 81, and the valve seat 81 is installed on one end of the valve 756.

[0034] The end of the outlet tube 84 away from the valve seat 81 is fixedly connected to the pressurized firing probe 9.

[0035] As can be seen from the above, by using the firing circuit of the bomb disposal robot 1 to control the cryogenic solenoid valve 758, the discharge structure 75 introduces the liquid in the self-pressurized liquid nitrogen tank 74 into the hose 8 through the cryogenic solenoid valve 758, and then the pressurized firing probe 9 exerts force instantaneously to directly strike into the interior of the object, thereby achieving the purpose of spraying liquid nitrogen to dispose of the explosive.

[0036] Preferably, the pressurized firing probe 9 is installed inside the clamping device 3.

[0037] As can be seen from the above, the pressurized firing probe 9 can be fixed by the clamping device 3.

[0038] Furthermore, this design is intended for emergency response at explosive sites, particularly for high-risk explosives and explosive devices such as uncontrollable electronically controlled and time-delayed electronic devices. In the application of this design, a 15 to 20 kg self-pressurized liquid nitrogen tank 74 is used as the core component. This self-pressurized liquid nitrogen tank 74 is placed between two limiting arc plates 73 to ensure its stability and safety during operation. Subsequently, we connect the hose 8 to the outlet tube 84 and install the pressurized firing probe 9 inside the clamping device 3.

[0039] Once the location of the core area of ​​the explosive is determined, the bomb disposal robot 1 is moved by remote control. The robot moves by pulling the cart 71 through the connecting rod 6. The cart 71 moves together with the self-pressurized liquid nitrogen tank 74 through the limiting arc plate 73 that is firmly connected to it. When the bomb disposal robot 1 and the self-pressurized liquid nitrogen tank 74 move to the core area of ​​the explosive, the firing circuit of the bomb disposal robot 1 can be used to control the opening of the cryogenic solenoid valve 758.

[0040] At this time, the discharge structure 75 will quickly introduce the cryogenic liquid nitrogen in the self-pressurized liquid nitrogen tank 74 into the hose 8 through the cryogenic solenoid valve 758. Immediately afterwards, the pressurized firing probe 9 will exert force in an instant to spray the liquid nitrogen directly into the interior of the explosive. This method of spraying liquid nitrogen can effectively dispose of the explosive and reduce its explosion risk.

[0041] By fully utilizing the advantages of remote control and combining the technical characteristics of liquid nitrogen tanks, this design successfully integrates the two types of equipment. This innovative design mainly solves a major problem faced in explosives disposal operations, namely the huge threat posed to professionals by uncontrollable and potentially explosive electronic remote-controlled and time-delayed electronic explosives. By achieving remote unmanned operation in the core area, this design greatly improves the safety and efficiency of explosives disposal operations.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
