Description

Technical Field

[0001] The utility model relates to a pressure-sensing explosive disposal training device, belonging to the technical field of explosive disposal training. Background Art

[0002] Explosive ordnance disposal personnel are responsible for protecting the safety of life and property. When faced with dangerous explosives, they must remain calm and decisive. Through precise explosive ordnance disposal simulation training, their actual combat capabilities and emergency response levels can be continuously improved. In a simulated environment, they learn how to identify different types of explosives, master complex demolition techniques, and conduct various emergency response drills. This high-intensity training not only hones their professional skills, but also cultivates their psychological qualities in emergency situations, enabling them to quickly make accurate judgments and actions when facing real dangers. For example, the Chinese utility model patent with the authorization announcement number CN213518755U discloses a simulated explosion training device with exposed wires, and specifically discloses a closed box, two power supplies, two electromagnetic relays and an explosion simulator; the "cross" control of the electromagnetic coil circuits of the two electromagnetic relays and the contact parts realizes the association of the two electrical circuits. Using the simulated explosion training device with exposed wires, it is necessary to use other short-circuit wires to keep the electrical circuits of the power supply and the corresponding electromagnetic coil circuit closed, and then cut the winding wires, and then separate the simulated explosion training device and the "hostage" or specific object to successfully dispose of the explosive ordnance. However, this solution cannot simulate pressure-triggered bombs, so a device is needed to specifically train bomb disposal personnel in their pressure control capabilities. Utility Model Content

[0003] The purpose of the utility model is to provide a pressure-sensing explosive disposal training device, which can train explosive disposal personnel in their pressure control ability during the explosive disposal process and has the advantages of being simple, practical, flexible and adjustable.

[0004] The technical solution of the utility model is as follows: a pressure-sensing bomb disposal training device comprises a fixed frame, an operating table is slidably connected to the fixed frame, and a plurality of explosive cartridges are placed on the operating table; a strap is fixedly connected to the operating table, and the strap is wrapped around the outside of the explosive cartridge; a control box is provided on the strap; pressure regulating mechanisms are symmetrically arranged on both sides of the fixed frame, and the pressure regulating mechanisms are connected to the operating table; a plurality of sliding cylinders are symmetrically arranged on the upper part of the fixed frame, a first connecting rod is slidably connected to the lower part of the sliding cylinder, and the lower end of the first connecting rod is fixedly connected to the operating table; the upper end of the first connecting rod is connected to a spring; a pressure sensor is arranged in the sliding cylinder, and the sensing end of the pressure sensor is connected to the upper end of the spring.

[0005] The above-mentioned pressure-sensing bomb disposal training device, the pressure regulating mechanism includes a plurality of guide rods symmetrically arranged on both sides of the fixed frame, a plurality of counterweight blocks are slidably connected to the guide rods, a first through hole is horizontally penetrated on the counterweight block; a second through hole is vertically penetrated on the counterweight block; and a lifting component is arranged on the counterweight block.

[0006] The aforementioned pressure-sensing bomb disposal training device, the lifting component includes a base plate, on which sleeves are symmetrically arranged, and the sleeves are slidably connected to the guide rod; a hanging ring is provided in the middle of the upper end of the base plate; a second connecting rod is provided at the lower end of the base plate, and the second connecting rod is inserted into the second through hole of the counterweight block; a plurality of third through holes are linearly distributed on the second connecting rod, and the third through holes are flush with the corresponding first through holes.

[0007] In the aforementioned pressure-sensing bomb disposal training device, a latch is disposed transversely between the third through hole and the first through hole.

[0008] The aforementioned pressure-sensing bomb disposal training device has a plurality of buffer blocks disposed on the guide rod, and the buffer blocks are located below the counterweight block at the bottom.

[0009] The aforementioned pressure-sensing bomb disposal training device has pulleys symmetrically arranged on the upper end of the fixed frame; sliding blocks are arranged on both sides of the operating table, and the sliding blocks are slidably connected to the fixed frame; a connecting rope is connected to the hanging ring, and the connecting rope passes over the top of the pulley and is fixedly connected to the sliding block.

[0010] The aforementioned pressure-sensing bomb disposal training device has a buzzer disposed on the control box.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. In the utility model, the trigger pressure can be controlled by the pressure regulating mechanism. After setting the trigger pressure, the trainee needs to perform the bomb disposal operation on the explosive cartridge on the operating table. During the bomb disposal process, if the trainee causes pressure changes on the operating table, the first connecting rod will slide down along the sliding tube, causing the spring to pull the sensing end of the pressure sensor. The pressure sensor senses the pressure change and transmits the signal to the control box, which gives a prompt to simulate the bomb disposal failure. The spring can prevent the trainee from accidentally operating the operating table and causing it to slide down quickly, thereby damaging the pressure sensor, and has a buffering effect.

[0013] 2. The weight of the lifting component of the utility model needs to be the same as the total weight of the operating table and the components on it. Then, according to the required trigger pressure, a corresponding number of counterweights are selected, and a latch is inserted into the first through hole on the bottom counterweight. The latch is inserted from the first through hole on one side and passes through the third through hole and then out of the first through hole on the other side, so that the counterweights are connected to the lifting component. When the pressure exerted by the trainee on the operating table exceeds the set trigger pressure, the sliding blocks on both sides of the operating table slide down along the fixed frame, and the sliding blocks make the lifting component and the counterweight slide upward along the guide rail together through the connecting rope. Therefore, the present invention can change the size of the trigger pressure through the pressure adjustment mechanism according to the actual situation, so as to facilitate the trainees to carry out training with different pressure levels and improve the training effect.
