Description

Technical Field

[0001] This utility model relates to the field of fire extinguishing device technology, and in particular to a missile lead test stand with a fire extinguishing mechanism. Background Technology

[0002] A missile fuse is an explosion control system composed of sensors, an ignition mechanism, and a safety mechanism. It controls the warhead to detonate at the optimal time by sensing environmental and target information. It has four basic functions: safety control, safety disarming, target perception, and detonation control. In fact, during the missile design and manufacturing stage, a large number of tests need to be conducted on the missile fuse, including its operational stability under extreme conditions such as extreme cold and humid heat, and its reliability in tilting collision tests at different large turning angles. However, existing missile fuse testing devices generally lack a fire extinguishing mechanism.

[0003] For example, Chinese utility model patent CN115014137B discloses a small-caliber projectile fuse large angle of impact ignition test system and its test method. Although this solution simulates the angle of impact of the fuse when it hits the target by adjusting the angle-adjustable bracket to rotate around the axis, thus realizing the function of testing mechanical and electromechanical fuses, if an abnormal situation occurs during the test, such as the ignition device being accidentally triggered or the circuit being short-circuited, it may cause an accidental fire or explosion. If the test device cannot be cooled down quickly in time and the spread of fire cannot be stopped, then the missile fuse test device may pose a potential danger to the laboratory and personnel.

[0004] In view of this, a missile fuse test stand with a fire extinguishing mechanism is proposed to solve the above problems. Utility Model Content

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0021] Example:

[0022] Please combine Figures 1-3 This embodiment of a missile fuse test stand with a fire extinguishing mechanism includes a workbench 1 and an impact test mechanism 3 installed on its upper side. In this embodiment, the impact test mechanism 3 is composed of a fuse loading function module, a height lifting module, a collision angle setting function module, and a gunpowder explosion impact function module.

[0023] Please combine Figure 1 As shown, a simulated collision platform 6 is installed on the upper side of the workbench 1. The material of the simulated collision platform 6 can be used to simulate various target attack materials, such as aircraft carrier steel plates, tank steel plates, etc.

[0024] Please combine Figure 1 Two turntables 2 are rotatably connected to the upper side of the workbench 1. The two turntables 2 are arranged in a circular array around the simulated collision platform 6. A threaded rod 14 is rotatably connected to the upper side of each turntable 2. A support 15 is rotatably connected to the upper end of each threaded rod 14. The support 15 provides support for the rotation of the fire extinguisher nozzle 16.

[0025] Please combine Figure 1 As shown, each support 15 is rotatably connected to a fire extinguisher nozzle 16. In this embodiment, the fire extinguisher is a dry powder fire extinguisher, which is connected to the outside through a hose to provide a continuous supply of extinguishing agent to the fire extinguisher nozzle 16. The hose can also provide reasonable space for the swing range of the fire extinguisher nozzle 16.

[0026] Please combine Figure 1 As shown, the upper side of the turntable 2 is provided with an up-and-down drive mechanism that causes the fire extinguisher nozzle 16 to swing up and down, the lower side of the workbench 1 is provided with a left-right drive mechanism that causes the fire extinguisher nozzle 16 to swing left and right, and the fire extinguisher nozzle 16 is provided with a fire extinguishing detection mechanism.

[0027] Please combine Figure 3 As shown, the up-down drive mechanism includes a limiting cylinder 5 fixedly connected to the upper side of each turntable 2. The inner side of the upper end of the limiting cylinder 5 is rotatably connected to the outer side of the upper end of the threaded rod 14. Each limiting cylinder 5 has a limiting slot 13. The inner side of the limiting cylinder 5 is provided with a connecting rod pushing mechanism that causes the fire extinguisher nozzle 16 to swing up and down.

[0028] Please combine Figure 3 As shown, the linkage pushing mechanism includes a sleeve 18 that is threadedly connected to the threaded rod 14. The outer side of each sleeve 18 is slidably connected to the inner side of the limiting cylinder 5. A slide is fixedly connected to the outer side of each sleeve 18. The outer side of each slide is slidably connected to the inner side of the limiting groove 13. A connecting rod 4 is rotatably connected to one side of the slide. The end of each connecting rod 4 away from the slide is rotatably connected to one side of the fire extinguisher nozzle 16.

[0029] With the above technical solution, when the threaded rod 14 rotates, under the limiting action of the limiting slot 13 on the slide table, the sleeve 18 will move up and down along the inside of the limiting cylinder 5.

[0030] Please combine Figure 3 As shown, the left and right drive mechanism includes a first pulley 12 fixedly connected to the lower side of each turntable 2. A first servo motor 7 is installed on the lower side of the first pulley 12. The output end of each first servo motor 7 passes upward through the first pulley 12 and is fixedly connected to the lower end of the threaded rod 14. A pulley drive mechanism that makes the first pulley 12 reciprocate left and right is provided on the lower side of the worktable.

[0031] Through the above technical solution, the No. 1 servo motor 7 can swing in a consistent manner with the No. 1 pulley 12, thereby driving the fire extinguisher nozzle 16 to swing.

[0032] Please combine Figure 3 As shown, the belt pulley drive mechanism includes two support seats 10 fixedly connected to the lower side of the worktable 1. A second servo motor 8 is installed on the lower side of each support seat 10, and the second servo motor 8 is supported by the support seat 10.

[0033] Please combine Figure 3 As shown, the output end of the second servo motor 8 passes upward through the support base 10 and is fixedly connected to the second pulley 11. The second pulley 11 and the first pulley 12 are connected by a belt 9.

[0034] The transmission state between the second pulley 11 and the first pulley 12 is maintained by belt 9;

[0035] Please combine Figure 3 As shown, the fire extinguishing detection mechanism includes a flame sensor 17 installed on the upper side of each fire extinguisher nozzle 16. In this embodiment, the flame sensor 17 is a far-infrared flame sensor. The far-infrared flame sensor can detect infrared light with a wavelength in the range of 700 nanometers to 1000 nanometers, and the detection angle is 60 degrees. Its sensitivity reaches its maximum when the infrared light wavelength is around 880 nanometers. The far-infrared flame probe converts the intensity change of the external infrared light into a change in current. The change in value in the range of 0 to 255 is reflected by the A / D converter, and an electrical signal is generated and sent out. In addition, the stronger the external infrared light, the smaller the value; the weaker the infrared light, the larger the value.

[0036] The implementation principle of a missile lead wire test stand with a fire extinguishing mechanism in this embodiment is as follows: When the impact test mechanism 3 on the workbench 1 falls and collides with the simulated collision platform 6, causing a fire, the flame sensor 17 can detect the fire source or other heat sources with wavelengths in the range of 700 nanometers to 1000 nanometers, and promptly respond by sending signals to the second servo motor 8 and the first servo motor 7. First, the second servo motor 8 drives the second pulley 11, which in turn drives the first pulley 12 to rotate via the belt 9. Since the first servo motor 7 is installed on the first pulley 12... The first pulley 12 is installed on the lower side of the turntable 2. Therefore, when the first pulley 12 rotates, it can drive the turntable 2, the limiting cylinder 5, the fire extinguisher nozzle 16 and the first servo motor 7 to swing as a whole, thereby realizing the function of swinging and extinguishing fire within the horizontal angle range. Secondly, when the first servo motor 7 is started, it can drive the threaded rod 14 to rotate. Under the action of the upper limit groove 13 of the limiting cylinder 5 limiting the sleeve 18, the sleeve 18 can be pushed to move up and down along the limiting groove 13, thereby realizing the function of pushing the fire extinguisher nozzle 16 to swing up and down to extinguish fire with the help of the connecting rod 4.

[0037] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
