Description

Technical Field

[0001] The utility model relates to the technical field of fuzes, in particular to a multi-safety timing device. Background Art

[0002] In modern warfare and military operations, the destruction of unexploded ordnance (UXO) is a pressing safety issue. Unexploded ordnance (UXO) can remain due to environmental factors or combat damage, posing a threat not only to the surrounding environment but also to the safety of personnel involved. Therefore, the effective and safe destruction of these UXO is a crucial task in both the military and engineering fields.

[0003] Traditional ammunition destruction methods often rely on manual labor, requiring operators to approach potential sources of danger to handle them, potentially leading to safety accidents. Existing drone hoisting devices typically use ammunition drop destruction methods and rely on manually controlled local detonations. While this can reduce direct risks to a certain extent, it still cannot ensure the safety of the drone and its operators. To improve destruction efficiency, combining ammunition destruction with drone technology and optimizing the structural design of the ammunition itself are key. The fuze is a key detonating device installed on the ammunition that detonates the warhead based on target information and environmental conditions. Among them, the delayed detonation function can control the timing and location of the explosion, improving mission success rates and reducing collateral damage. However, current delayed fuze mechanisms are often complex and sophisticated, resulting in high manufacturing and maintenance costs and a tendency to malfunction in complex environments.

[0004] When drones perform ammunition destruction missions, the delay fuse ensures that the drone can safely evacuate after placing the destroyed ammunition. Therefore, the development of a simplified and reliable delay fuse device can significantly improve the efficiency of drones in performing such missions.

[0005] Announcement No. CN 217110693 U discloses a fuze delay mechanism, including a shell, a turntable, a coil spring, a screw, an outer electrode and an inner electrode. The upper and lower ends of the screw are rotatably connected to the top wall and bottom wall of the shell respectively. The screw and the side of the shell are provided with through holes, and a latch is provided in the through hole. The turntable is located in the middle of the shell, and a ratchet and a pawl are provided between the turntable and the shell. The coil spring is fixed between the screw and the turntable. A slider is threadedly connected to the bottom of the screw, and the slider slides up and down in the shell. The outer electrode is fixed to the bottom of the slider, and the inner electrode is fixed to the bottom wall of the shell. In this scheme, the coil spring can be tightened by rotating the turntable, and then the latch is released to allow the screw to rotate freely. The screw rotates under the action of the elastic restoring force of the coil spring, and the slider connected to the screw rotation slides downward, thereby making the outer electrode and the inner electrode contact, thereby detonating the fuze and realizing delayed detonation of the fuze. Although delayed detonation operations can be achieved, the device has insufficient accuracy in delay time and a relatively simple safety design. It lacks multiple insurance mechanisms and has potential risks of misoperation. In complex environments, the accuracy and safety of the delay may not be fully guaranteed. Utility Model Content

[0006] The purpose of the utility model is to provide a multi-insurance timing device.

[0007] The innovation of this utility model is that the delayed triggering of the fuse is achieved by combining the pushing mechanism with the electronic components, and the time when the pushing mechanism triggers the device path is controlled by the clock mechanism, so as to ensure the delay accuracy and improve the safety and reliability of the device.

[0008] To achieve the above-mentioned purpose of the utility model, the technical solution of the utility model is: a multi-safety timing device, comprising a housing, characterized in that the housing is provided with a chamber, a driving mechanism is provided in the chamber, a sliding assembly is provided in the housing, a slideway for the sliding assembly to slide, two channels are provided in the housing to connect the chamber and the slideway, the two channels are respectively channel 1 and channel 2, an electric actuator is provided in channel 1 that is connected to the driving mechanism and limits the movement of the sliding assembly in the slideway, a detonator is provided on the sliding assembly, an electric ignition tube is provided in channel 2 that is connected to the driving mechanism and matches the detonator, a power supply is provided on the housing, the driving mechanism is connected to the power supply, a push rod is provided on the driving mechanism, an electronic assembly is provided on the housing, a limiter is provided on the housing that limits the electrical connection between the push rod of the driving mechanism and the electronic assembly, and the driving mechanism is controlled by a clock mechanism. The driving mechanism realizes electrical connection of the entire device through the driving mechanism, and the triggering time is controlled by the clock mechanism, thereby ensuring precise control of the triggering time of the device and improving the safety of operation.

[0009] Furthermore, the pushing mechanism includes several sliding rods, sliders that slide on the sliding rods, and a first elastic component that pushes the sliders out. The sliders are equipped with racks that mesh with the clockwork mechanism and are provided with sockets. The limiting element is a pin with one end inserted into the socket and the other end extending out of the housing. The elastic component stores energy when the sliders are restrained, improving the device's responsiveness and flexibility. The racks on the sliders mesh with the clockwork mechanism to ensure precise time control. The addition of the pin as a limiting element effectively prevents excessive movement of the slider, enhancing the device's safety and reliability.

[0010] Furthermore, the housing is equipped with a safety mechanism that prevents the latch from sliding out. The safety mechanism includes a safety block with a through hole for the latch, and a safety lever with a waist-shaped hole for the latch. The waist-shaped hole has a large hole at one end and a small hole at the other. The safety lever is equipped with a second elastic component that tightens the latch against the end of the small hole. The design of the safety block and safety lever in the safety mechanism effectively prevents the latch from sliding out, improving the safety of the entire device. The combination of the through hole in the safety block and the waist-shaped hole ensures that the latch remains locked at all times.

[0011] Furthermore, the clockwork mechanism includes a gear set meshing with the rack and a pendulum for controlling the rotation speed of the gear set. The pendulum is used to control the rotation of the gear set, ensuring that the gear set drives the rack at a constant speed, thereby improving the accuracy of the device's time control.

[0012] Furthermore, the sliding assembly includes a slider and a spring seat for pushing the moving block along the slideway. The spring seat is fixed to one end of the slideway. The moving block is provided with a pull pin hole. A pull pin is located in the pull pin hole to limit the movement of the moving block within the slideway. One end of the pull pin extends outside the housing. The detonator is provided on the moving block. The pull pin limits the moving block, preventing accidental contact between the detonator and the electric ignition tube, thereby improving the safety of the device.

[0013] Furthermore, the housing is equipped with a protective cover for sealing the inner chamber of the housing, and a partition plate for isolating the slideway from the outside world. The addition of the protective cover and partition plate effectively prevents external factors from affecting the interior of the device, facilitates disassembly and maintenance by staff, and improves the stability of the device.

[0014] Furthermore, the protective cover and the partition plate are both connected to the housing by bolts, thereby ensuring a stable connection between the partition plate and the protective cover and the housing, thereby improving the stability and safety of the entire device.

[0015] Furthermore, the housing, protective cover, and partition are all made of ABS material. Using ABS material for manufacturing makes the housing, protective cover, and partition have excellent impact resistance and chemical resistance, thereby increasing the service life of the entire device and reducing production and maintenance costs.

[0016] Furthermore, the electronic assembly includes a switch and a circuit board for receiving external commands after power is applied, and the switch and circuit board are connected by a wire. Connecting the switch and circuit board by wire achieves a modular design, facilitates debugging and troubleshooting, and improves the convenience of device debugging.

[0017] The beneficial effects of the utility model are:

[0018] 1. In this utility model, the electrical connection of the entire device is achieved through a pushing mechanism, and the triggering time is controlled by a clock mechanism, ensuring the precise control of the device triggering time and improving the safety of operation. The addition of a latch as a limiter effectively prevents excessive movement of the slider. The design of the safety block and safety rod in the safety mechanism effectively limits the slipping of the latch. The through hole on the safety block is combined with the waist-shaped hole to improve the safety of the entire device.

[0019] 2. This utility model utilizes an elastic component to store energy when the slider is limited, improving the device's response speed and flexibility. The rack on the slider meshes with the clock mechanism, and the pendulum is used to control the rotation of the gear set, ensuring that the gear set drives the rack at a constant speed, thereby improving the accuracy of the device's time control. The switch and circuit board are connected by wires, achieving a modular design that facilitates debugging and troubleshooting, thereby improving the convenience of device debugging.

[0020] 3. The protective cover and partition plate added in this utility model effectively prevent external factors from affecting the interior of the device and facilitate disassembly and maintenance by staff, thereby improving the stability of the device. The partition plate and protective cover are connected stably to the housing through bolts, thereby improving the stability of the entire device. The use of ABS material makes the housing, protective cover and partition plate have excellent impact resistance and chemical resistance, thereby increasing the service life of the device.
