Description

Technical Field

[0001] This utility model relates to the field of artillery firing range alarm technology, and in particular to a self-propelled artillery firing range alarm device. Background Technology

[0002] Currently, self-propelled artillery firing range safety devices mainly rely on two types of technologies: one is a mechanical limiting structure, which uses gear sets and limiting blocks to restrict the rotation angle of the directional wheel; the other is an electronic alarm device, which uses an angle sensor to detect the barrel's azimuth and trigger a buzzer. While these solutions can achieve basic protection functions, they suffer from problems such as slow response and high false alarm rates.

[0003] To improve alarm response speed, existing technologies attempt to improve circuit triggering mechanisms. For example, photoelectric sensors are used to detect out-of-range glare, but these require an additional power supply module and are susceptible to interference from muzzle smoke. Another solution uses magnetic proximity switches, but the magnetic induction distance is significantly affected by temperature, with a detection error of ±1.5° at -20°C. None of these improvements solve the core problem—how to achieve a delay-free physical contact triggering mechanism. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a self-propelled artillery firing range alarm device. Through the point contact triggering mechanism of double vertical conductive rods and conductive slip rings, it simplifies the structure, enhances vibration resistance and reliability, and achieves millisecond-level real-time alarm response and rapid calibration and maintenance, significantly improving the practical effectiveness of artillery firing range safety protection.

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

[0006] A self-propelled artillery firing range alarm device includes:

[0007] A directional wheel linkage mechanism, wherein the end of the rotating shaft of the directional wheel linkage mechanism is provided with a conductive slip ring; the conductive slip ring is fixed coaxially with the rotation axis of the target artillery barrel;

[0008] Two safe firing range calibration modules are provided. Each safe firing range calibration module includes an insulating base and a vertical conductive rod embedded in the insulating base. The distance range between the two vertical conductive rods corresponds to a preset safe firing range angle. When the target gun barrel rotates to the boundary of the safe firing range, the conductive slip ring contacts the end point of the vertical conductive rod to conduct electricity.

[0009] An integrated alarm is electrically connected to the conductive slip ring via a wire. The integrated alarm includes a buzzer and a red warning light.

[0010] Preferably, the safe firing range calibration module is fixed to the inner wall of the turret by a bracket.

[0011] Preferably, the sound pressure level of the buzzer is ≥90dB, and the light intensity of the red warning light is ≥200cd.

[0012] Preferably, the wires of the integrated alarm are sheathed with flame-retardant corrugated tubing.

[0013] Preferably, the contact surface of the conductive slip ring is plated with a silver-nickel alloy layer, the thickness of which is 0.2-0.5 mm.

[0014] Preferably, it further includes: a redundant alarm circuit, the input terminal of which is connected in parallel to the two poles of the conductive slip ring, and the output terminal of which is connected to a flashing warning sign on the outside of the turret; the flashing frequency of the flashing warning sign is 2-4Hz.

[0015] Preferably, the lampshade of the red warning light has a double-layer structure; the inner layer of the double-layer structure is a polycarbonate diffuser plate, and the outer layer of the double-layer structure is a tempered glass protective cover, with a 1.2-1.5mm air insulation layer between the two layers.

[0016] Preferably, the annular groove of the conductive slip ring is filled with conductive grease; the dropping point of the conductive grease is ≥260℃, the volume resistivity of the conductive grease is ≤1×10-3Ω·cm, and the filling thickness of the conductive grease is 80-90% of the groove depth.

[0017] According to the specific embodiments provided by this utility model, the following technical effects are disclosed:

[0018] This invention simplifies the structure and improves the reliability of the firing range alarm device through a point-contact triggering mechanism using dual vertical conductive rods and a conductive slip ring. The rigid structure of the vertical conductive rods effectively resists high-frequency vibrations during artillery firing, avoiding the contact problems caused by deformation of traditional arc-shaped conductive sheets. The discrete contact layout simplifies the installation and calibration process, requiring only adjustments to two boundary calibration points to quickly adapt to different firing range requirements, significantly shortening combat preparation time. At the same time, the direct physical contact conduction method eliminates the signal conversion stage, enabling alarm response speeds to reach millisecond levels, fundamentally solving the delay problem of electronic sensor solutions. The modular design also facilitates flexible deployment in confined turret spaces, and individual conductive rods can be replaced independently when damaged, greatly reducing maintenance costs. The overall solution ensures real-time alarm accuracy while also possessing environmental adaptability and equipment practicality. Attached Figure Description

[0024] 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.

[0025] The purpose of this invention is to provide a self-propelled artillery firing arc alarm device. Through a point contact triggering mechanism between two vertical conductive rods and a conductive slip ring, it simplifies the structure, enhances vibration resistance and reliability, and achieves millisecond-level real-time alarm response and rapid calibration and maintenance, significantly improving the practical effectiveness of artillery firing arc safety protection.

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Figure 1 This is a schematic diagram of the alarm device structure provided in an embodiment of the present utility model, as shown below. Figure 1 As shown, this utility model provides a self-propelled artillery firing range alarm device, comprising:

[0028] The directional wheel linkage mechanism 1 has a conductive slip ring 2 at the end of its rotating shaft; the conductive slip ring 2 is fixed coaxially with the rotation axis of the target artillery barrel 4.

[0029] Two safe firing range calibration modules 3, each of the safe firing range calibration modules 3 includes an insulating base 31 and a vertical conductive rod 32 embedded in the insulating base 31; the distance range between the two vertical conductive rods 32 corresponds to the preset safe firing range angle; when the target gun barrel 4 rotates to the boundary of the safe firing range, the conductive slip ring 2 contacts and conducts electricity with the end point of the vertical conductive rod 32;

[0030] An integrated alarm 5 is electrically connected to the conductive slip ring 2 via a wire. The integrated alarm 5 includes a buzzer and a red warning light.

[0031] This utility model's self-propelled artillery firing range alarm device achieves real-time monitoring and alarm of the artillery firing range by combining a directional wheel linkage mechanism 1 and a conductive slip ring 2. When the artillery barrel's shaft rotates around the conductive slip ring 2, the conductive slip ring 2 contacts the endpoints of the vertical conductive rods 32 on the two safe firing range calibration modules 3, forming a closed circuit, thereby triggering the integrated alarm 5. The integrated alarm 5 can be connected to the conductive slip ring 2 via precisely designed wires. Its buzzer emits a sound ≥90dB, while a red warning light illuminates under a light intensity ≥200cd, reminding the operator to pay attention to the artillery's safe firing range. To ensure the device can work effectively under any operating conditions, the contact surface of the conductive slip ring 2 is plated with a silver-nickel alloy layer, the thickness of which is controlled between 0.2-0.5mm, enhancing the conductivity and durability of the contact.

[0032] To enhance the reliability of this alarm device, this invention also includes a redundant alarm circuit, whose input is connected in parallel to the two poles of the conductive slip ring 2. This ensures that the external flashing warning sign can still function even in the event of a main circuit failure, with the flashing frequency set at 2-4Hz. Furthermore, the red warning light cover adopts a double-layer structure: an inner layer of polycarbonate diffuser plate and an outer layer of tempered glass protective cover, forming a 1.2-1.5mm air insulation layer between them to improve light intensity and protective performance. The annular groove of the conductive slip ring 2 is filled with conductive grease to ensure good conductivity under high-temperature conditions (dropping point ≥260℃) and maintain its volume resistivity at ≤1×10-3Ω·cm, thereby improving the overall stability and service life of the alarm device and enabling safe and stable operation in harsh environments.

[0033] Specifically, such as Figure 2As shown, in the self-propelled artillery firing arc alarm device of this invention, two vertical conductive rods 32 are set perpendicular to the ground. They can also intersect to form an angle, primarily to enhance the device's adaptability and flexibility to different firing arc angles. Through an adjustable bracket design, the user can flexibly adjust the angle between the conductive rods (e.g., from 10° to 45°) according to the specific operational needs of the artillery, ensuring that the conductive slip ring 2 maintains effective contact with the endpoints of the conductive rods at various firing angles, thereby accurately triggering the alarm function. This design not only improves the reliability of signal detection but also adapts to the requirements of different environments and missions, ensuring safe artillery firing while reducing the probability of false alarms.

[0034] To achieve adjustable and stable angles, the bracket features a locking function to ensure the position of the conductive rod does not easily change after adjustment. Furthermore, the end of the conductive rod can be designed with a slightly curved structure to ensure effective contact with the conductive slip ring 2 regardless of the gun's angle. This design, combined with the flexible placement of the conductive rod, allows for real-time monitoring of its operating status and provides feedback on angle changes via built-in sensors, enabling timely adjustments and maintenance. Through these methods, this device not only improves safety performance but also achieves greater operational convenience through intelligent monitoring, fully complying with the disclosure requirements of the Patent Law for utility models.

[0035] When the target artillery barrel 4 rotates to the boundary of the safe firing range, the conductive slip ring 2 contacts the end point of the vertical conductive rod 32, thus forming a closed circuit. Specifically, the conductive slip ring 2 is fixed coaxially with the rotation axis of the artillery. As the artillery rotates, the conductive slip ring 2 moves with the rotation of the artillery barrel. When the rotation angle of the artillery barrel reaches the preset safe firing range boundary, the contact surface of the slip ring will reliably contact the end point of the vertical conductive rod 32, thereby realizing the circuit connection. The contact signal of this invention can not only accurately reflect the firing status of the artillery, but also effectively reduce the possibility of false alarms.

[0036] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0037] This document uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. Furthermore, those skilled in the art will recognize that, based on the ideas of this utility model, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this utility model.
