Description

Technical Field

[0001] This application relates to the technical field of simulation training, and in particular to a simulated landmine. Background Technology

[0002] Simulated landmines are highly realistic training tools used for mine clearance training by engineers and tactical squad battlefield crossing drills. Their core value lies in helping trainees master mine clearance skills and tactical awareness in a near-real battlefield environment through safe and controllable simulation. The main drawback of existing simulated landmines is the lack of an alarm capability. That is, when personnel step on the landmine or use a mine detector to probe it with excessive force, there is no warning (simulating a landmine explosion), resulting in poor teaching effectiveness. Utility Model Content

[0003] To address the aforementioned technical problems, this application provides a simulated landmine.

[0004] The above-mentioned inventive objective of this application is achieved through the following technical solutions:

[0005] A simulated landmine includes a cylindrical base and a housing. The outer wall of the cylindrical base is provided with a charging port, and the interior of the cylindrical base is provided with a cavity. The housing is snapped onto the top of the cylindrical base, and a pressure cap is provided at the end of the housing away from the cylindrical base.

[0006] A waterproof switch is fixedly installed in the center of the cylindrical base, and a triggering mechanism is fixedly connected inside the housing. When the cover is subjected to downward pressure, the triggering mechanism abuts against the waterproof switch.

[0007] A controller is fixedly installed inside the cylindrical chassis. The controller integrates a buzzer and a delay circuit. The buzzer is electrically connected to the waterproof switch.

[0008] By adopting the above technical solution, the linkage design of the pressure cap and the triggering mechanism ensures that when the pressure cap is subjected to downward pressure (such as stepping or being pierced by a mine probe), the triggering mechanism can accurately trigger the waterproof switch. After triggering, the buzzer will continue to sound an alarm for 20 seconds through a delay circuit, which can simulate the "explosion" warning effect of a real landmine and avoid continuous noise interference to training after accidental triggering.

[0009] Optionally, the triggering mechanism includes a pressure column, a spring, and a disc. One end of the pressure column is fixedly connected to the center of the inside of the pressure cap, and the other end of the pressure column extends vertically to the top of the waterproof switch.

[0010] The spring is sleeved on the outside of the pressure column, one end of the spring is fixedly connected to the inner wall of the pressure cap, and the other end of the spring is fixedly connected to the surface of the disc.

[0011] The disc has a through hole in the center, and the end of the pressure column away from the cover passes through the through hole. A sealing ring is fixedly connected to the outer wall of the disc, and the disc is fixedly connected to the housing through the sealing ring.

[0012] By adopting the above technical solution, the spring is sleeved on the outside of the pressure column. When the pressure cap is pressed down, the spring provides a restoring force, so that the pressure cap automatically returns to its initial state, realizing the reuse of the simulated landmine. The sealing ring on the outer wall of the disc is fixedly connected to the housing, effectively isolating external moisture and dust from entering the housing, protecting the internal electronic components to work stably in humid or dusty environments. The design of the pressure column passing through the through hole of the disc ensures that the pressure is transmitted vertically to the waterproof switch, avoiding lateral force interference with triggering accuracy and improving the sensitivity of feedback during training.

[0013] Optionally, the buzzer is electrically connected to a 2.4G wireless receiver unit for receiving external remote control signals and triggering the buzzer alarm.

[0014] By adopting the above technical solution, the buzzer is connected to the remote control via a 2.4G wireless receiver unit, allowing instructors to remotely trigger the alarm, simulate a scenario where a landmine is remotely detonated by the enemy, or correct trainees' operational errors and expand the diversity of training tactics.

[0015] Optionally, the top surface of the gland may be removably snapped with a safety pin.

[0016] By adopting the above technical solution, the safety pin can be detachably snapped onto the top of the pressure cover. Inserting the pin during transportation or non-training states can lock the pressure cover, preventing accidental pressure from triggering an alarm and ensuring the safety of equipment storage and carrying. Pulling out the pin before training can activate the equipment. The operation is simple and suitable for scenarios that require quick switching of training states, such as live-fire exercises and paused explanations.

[0017] Optionally, a waterproof tape is fixedly connected to the connection between the housing and the cylindrical chassis, and a waterproof cap is provided for the charging port.

[0018] By adopting the above technical solution, the connection between the shell and the cylindrical chassis is sealed with waterproof tape, and the charging port is equipped with a waterproof cap. This double protection ensures that the equipment can be used normally in harsh environments such as rain and mud, thus extending its service life.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] 1. The linkage design of the pressure cap and the triggering mechanism ensures that when the pressure cap is subjected to downward pressure (such as stepping or being pierced by a mine probe), the triggering mechanism can accurately trigger the waterproof switch. After triggering, the buzzer will continue to sound an alarm for 20 seconds through a delay circuit, which can simulate the "explosion" warning effect of a real landmine and avoid continuous noise interference to training after accidental triggering.

[0021] 2. The spring is sleeved on the outside of the pressure column. When the pressure cap is pressed down, the spring provides a restoring force, so that the pressure cap automatically returns to its initial state, realizing the reuse of the simulated landmine. The sealing ring on the outer wall of the disc is fixedly connected to the housing, effectively preventing external moisture and dust from entering the housing and protecting the internal electronic components to work stably in humid or dusty environments. The design of the pressure column passing through the through hole of the disc ensures that the pressure is transmitted vertically to the waterproof switch, avoiding lateral force interference with triggering accuracy and improving the sensitivity of feedback during training.

[0022] 3. The buzzer is connected to the remote control via a 2.4G wireless receiver unit, allowing instructors to remotely trigger the alarm to simulate a scenario where a landmine is remotely detonated by the enemy, or to correct trainees' operational errors and expand the diversity of training tactics.

[0029] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0030] Reference Figure 1-3This application discloses a simulated landmine with a diameter of 5.6 cm and a height of 7 cm. It includes a cylindrical base 1 and a shell 2. The outer wall of the cylindrical base 1 is provided with a charging port 3, an antenna hole, and a sound hole (not shown in the figure). The charging port is provided with a waterproof cap 4. The antenna hole and the sound hole are treated with sealant inside. The cylindrical base 1 has a cavity inside. The shell 2 is snapped onto the top of the cylindrical base 1. A waterproof tape 13 is provided at the connection between the shell 2 and the cylindrical base 1. A pressure cap 5 is provided at the end of the shell 2 away from the cylindrical base 1. A safety pin 12 is detachably snapped onto the top surface of the pressure cap 5.

[0031] A waterproof switch 6 is fixedly installed in the center of the cylindrical chassis 1. A triggering mechanism is fixedly connected inside the housing 2. A controller 7 is fixedly installed inside the cylindrical chassis 1. The controller 7 integrates a buzzer and a delay circuit. The buzzer is electrically connected to the waterproof switch 6 and to a 2.4G wireless receiver unit, used to receive external remote control signals and trigger the buzzer alarm. The communication distance is ≤200 meters (up to 1KM with a base station or repeater). When the pressure cover 5 is subjected to downward pressure (such as stepping or being pierced by a mine probe), the triggering mechanism can accurately trigger the waterproof switch 6. After triggering, the buzzer will continue to sound the alarm for 20 seconds through the delay circuit.

[0032] Reference Figure 3-5 The triggering mechanism includes a pressure column 8, a spring 9, and a disc 10. One end of the pressure column 8 is fixedly connected to the center of the inside of the pressure cover 5, and the other end of the pressure column 8 extends vertically to the top of the waterproof switch 6. The spring 9 is sleeved on the outside of the pressure column 8, one end of the spring 9 is fixedly connected to the inner wall of the pressure cover 5, and the other end of the spring 9 is fixedly connected to the surface of the disc 10. A through hole is opened in the center of the disc 10, and the end of the pressure column 8 away from the pressure cover 5 passes through the through hole. A sealing ring 11 is fixedly connected to the outer wall of the disc 10, and the disc 10 is fixedly connected to the housing 2 through the sealing ring 11. Spring 9 is sleeved on the outside of pressure column 8. When pressure cap 5 is pressed down, spring 9 provides a restoring force, so that pressure cap 5 automatically returns to its initial state, realizing the reuse of simulated landmines. The sealing ring 11 on the outer wall of disc 10 is fixedly connected to housing 2, effectively isolating external moisture and dust from entering the interior of housing 2, protecting the internal electronic components to work stably in humid or dusty environments. The design of pressure column 8 passing through the through hole of disc 10 ensures that pressure is transmitted vertically to waterproof switch 6, avoiding lateral force interference with triggering accuracy and improving the sensitivity of feedback during training. The buzzer is connected to remote control via 2.4G wireless receiver unit, and instructors can remotely trigger the alarm to simulate the scenario of landmines being remotely detonated by the enemy.

[0033] The implementation principle of a simulated landmine in this application embodiment is as follows: A safety pin 12 is detachably snapped onto the top of the pressure cap 5. Inserting the pin during transport or non-training states locks the pressure cap 5, preventing accidental pressure triggering of the alarm. Removing the pin before training activates the device. When the pressure cap 5 is subjected to downward pressure (such as from being stepped on or pierced by a mine probe), the pressure column 8 accurately triggers the waterproof switch 6. After triggering, the buzzer continuously alarms for 20 seconds via a delay circuit, simulating the "explosion" warning effect of a real landmine while avoiding continuous noise interference during training after accidental triggering. Spring 9 is sleeved on the outside of pressure column 8. When pressure cap 5 is pressed down, spring 9 provides a restoring force, so that pressure cap 5 automatically returns to its initial state, realizing the reuse of simulated landmines. The sealing ring 11 on the outer wall of disc 10 is fixedly connected to housing 2, effectively isolating external moisture and dust from entering the interior of housing 2, protecting internal electronic components to work stably in humid or dusty environments. The design of pressure column 8 passing through the through hole of disc 10 ensures that pressure is transmitted vertically to waterproof switch 6, avoiding lateral force interference with triggering accuracy and improving the sensitivity of feedback during training.
