Embodiment 1

[0039] Embodiment 1: Preparation of combustible glue.

[0040] Weigh Al powder, Fe 3 o 4 powder, mix the two evenly to obtain Al / Fe 3 o 4 Mix the powder; weigh shellac, add it to absolute ethanol, and prepare a shellac absolute ethanol solution with a mass concentration of 5%; weigh Al / Fe 3 o 4 Mix the powder, add it to the above-mentioned shellac absolute ethanol solution, and stir until it is uniform to obtain a mixed solution; add glass fiber powder to the above-mentioned mixed solution, after stirring evenly, then add expandable graphite, and stir until it is uniform to obtain a combustible glue.

[0041] The dosage of each raw material is shown in the table below, wherein, the shellac / dehydrated ethanol solution in the 1# formula is prepared by adding 6.5g shellac to 156mL absolute ethanol; the shellac / dehydrated alcohol solution in the 2# formula The ethanol solution is prepared by adding 5g shellac to 100mL absolute ethanol; the shellac / absolute ethanol solution i...

Embodiment 2

[0043] Embodiment 2: Device for destroying unexploded bombs on the spot.

[0044] Such as figure 1 As shown, the device of the present invention is mainly composed of a movable base 1, a combustible rubber extruding mechanism, an ignition mechanism, a video monitoring system, a display platform (not shown) and a remote control 8 and other parts.

[0045] The movable base 1 is used as a carrier for carrying other parts and can move together with other parts. The base 1 can be a wheeled trolley or a crawler trolley.

[0046] The combustible rubber extruding mechanism includes a rubber storage tank 2 , an extruding pipe 3 and an extruding mechanism 4 . The glue storage tank 2 is arranged on the front end of the base 1, and is used for storing combustible glue, and the combustible glue is made by Example 1. The extruding tube 3 is arranged at the front end of the tank body of the rubber storage tank 2, and serves as an extruding channel for the combustible rubber. The tube body ...

Embodiment 3

[0050] Embodiment 3: method for destroying unexploded bombs on the spot.

[0051] The inventive method comprises the following steps:

[0052] A, the said unexploded ordnance destruction device on the spot of embodiment 2 is set;

[0053] b. Use the remote control to control the base to move towards the position of the unexploded bomb. At the same time, through the video display on the display platform, when the lower port of the extrusion tube of the combustible rubber extrusion mechanism is located directly above the fuze body of the unexploded bomb, the control The base stops running;

[0054] c. Control the extruding mechanism of the combustible rubber extruding mechanism to extrude the combustible rubber in the rubber storage tank. Observe through the video screen on the display platform. When the extruded combustible rubber completely covers the fuze body of the unexploded bomb, control The extrusion mechanism stops extrusion;

[0055] d. Control the base to move away...

Abstract

The invention provides an in-situ destruction device and an in-situ destruction method for an unexploded hand grenade. The device comprises a movable base, a combustible adhesive extrusion mechanism, an ignition mechanism and a video monitoring system which are arranged on the base, a display platform used for receiving the information of the video monitoring system, as well as a remote controller used for controlling the movable base, the combustible adhesive extrusion mechanism, the ignition mechanism and the video monitoring system. The in-situ destruction device and the in-situ destruction method, which are provided by the invention, are capable of safely, thoroughly and efficiently destructing the unexploded hand grenade in situ, without the need of additionally increasing an explosive with an explosion equivalent, and a safe distance of the unexploded hand grenade during destruction keeps the original safe distance; therefore, prevention measures have no need to be additionally increased in a hand grenade throwing field due to the destruction operation, the workload of the destruction for the unexploded hand grenade is reduced, and treatment working for the unexploded hand grenade in the hand grenade throwing field is greatly facilitated.

Description

technical field [0001] The invention relates to a device for destroying unexploded bombs and a method for destroying unexploded bombs, in particular to an on-site destruction device and method for unexploded bombs. Background technique [0002] Affected by the manufacturing process and cost, the misfire rate of grenades is generally high, so a large number of unexploded grenades will be produced during the grenade throwing training process. For the grenade that uses percussion-type ignition parts, the main reasons that cause it to explode but not explode are the decreased sensitivity of the needle-punched cap and the insufficient spring force of the torsion spring. The firing pin plate of the unexploded grenade has rebounded into place, and the firing pin is tightly pressed against the cap. Once it is stimulated by external environmental forces, it is likely to explode, which seriously threatens the safety of surrounding personnel and facilities and equipment, and interferes...
