Abstract
Description
Technical Field
[0001] This utility model relates to the field of artillery technology, and in particular to a laser-based rapid spade calibrator. Background Technology
[0002] After live-fire exercises or before storage, artillery barrels must be cleaned and dehumidified. In modern warfare, artillery, as the core combat force of the army, undertakes key tasks such as fire suppression and battlefield control. However, artillery positions are vulnerable to detection and countermeasures by counter-battery radar, drones, and other equipment. Therefore, the "hit-and-run" rapid combat mode has become a core means of improving survivability, and shortening the deployment time of artillery is the key to achieving this mode.
[0003] Existing hoist calibration technology has significant drawbacks:
[0004] 1. The spade calibration device with a laser galvanometer as its core works by using a laser to scan the target area via mirrors mounted on X and Y axis stepper motors, thereby calibrating the spade area. However, its drawbacks include complex X and Y axis control algorithms and a large size and weight due to the need for a power supply module, stepper motor drive module, light source module, and galvanometer module. This makes it completely unusable in actual working conditions.
[0005] 2. The hoisting calibration device with a single-line laser light as its core works by using a single-line laser light to align with the hoisting position line for calibration. Its disadvantages include severe laser energy loss, a line width of only 2mm, which makes the marking unclear due to its thinness, and difficulty in observation in bright environments. Utility Model Content
[0006] The purpose of this invention is to provide a laser-based rapid shovel calibrator to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0008] A laser-based rapid shovel calibrator includes an angle adjustment mechanism, a marking mechanism, and an optical projection lens. The angle adjustment mechanism includes an angle adjustment component and a universal rotating connecting rod connected together. The marking mechanism is connected to one end of the angle adjustment mechanism via the universal rotating connecting rod, and the optical projection lens is mounted on the marking mechanism.
[0009] Furthermore, the angle adjustment mechanism includes a mounting plate, lateral support seats, and a rotating shaft. The adjustment assembly includes an X-axis adjustment plate and a Y-axis adjustment plate. The two lateral support seats are secured on the mounting plate. A first shaft hole is provided at the end of each lateral support seat away from the mounting plate. A second shaft hole is provided on the universal rotating connecting rod. The rotating shaft passes through the first and second shaft holes. The end of the universal rotating connecting rod near the mounting plate is slidably connected to the Y-axis adjustment plate and the X-axis adjustment plate.
[0010] Furthermore, the angle adjustment mechanism includes a limiting steel sleeve, which is disposed between the universal rotating connecting rod and the lateral support seat and sleeved on the rotating shaft.
[0011] Furthermore, an adjusting nut is rotatably connected above the Y-axis adjusting plate.
[0012] Furthermore, a pressure plate is provided above the Y-axis adjustment plate, which can press the adjustment nut tightly.
[0013] Furthermore, the marking generating mechanism includes a housing, a support base, a laser heat sink, a laser tube mounting base, a laser tube, an optical fiber panel, and a projection lens mounting plate. The top of the housing is connected to the universal rotating connecting rod. The housing has an opening, and the projection lens mounting plate is installed at the opening. The support base is installed inside the housing on a side corresponding to the projection lens mounting plate. The laser heat sink is installed below the support base. The laser tube mounting base is slidably connected inside the laser heat sink, and the laser tube is installed inside the laser tube mounting base. The optical fiber panel is installed on the support base, and the projection lens mounting plate has mounting holes.
[0014] Furthermore, the marking mechanism also includes an optical fiber head, one end of which is connected to the emitting end of the laser tube, and the other end is connected to multiple optical fibers. The end of the optical fiber away from the laser tube is connected to one side of the optical fiber panel, and the other side of the optical fiber panel corresponds to the optical projection lens.
[0015] Furthermore, the housing is assembled from five housing mounting plates.
[0016] Furthermore, the optical projection lens is installed in the mounting hole. The optical projection lens includes a lens mount, a pressure ring, a lens, and a spacer. The lens and the spacer are spaced apart and embedded inside the lens mount, and pressure rings are provided at both ends of the lens mount for locking and fixing.
[0017] Furthermore, the retaining ring includes a first retaining ring and a second retaining ring, the lens includes a first lens, a second lens, a third lens, and a fourth lens, and the spacer includes a first spacer, a second spacer, and a third spacer. The spacer and the lens are installed inside the lens mount in the order of first lens, first spacer, second lens, second spacer, third lens, third spacer, and fourth lens. The first retaining ring and the second retaining ring are fixed from both ends of the lens mount.
[0018] Beneficial effects:
[0019] This invention eliminates the steps and waiting time required in the traditional initial process, thus improving calibration efficiency. It also reduces laser energy loss through fiber optic guidance and ensures that the marking lines remain clearly visible in bright environments with appropriate line width, solving the problem of blurry markings in existing technologies. Furthermore, it eliminates the need for complex control and power modules, resulting in a compact structure, small size, and light weight, which can meet the rapid deployment requirements in actual combat conditions. This shortens the "reconnaissance-decision-strike" cycle time and enhances the firepower suppression effect and battlefield survivability of artillery. Attached Figure Description

[0031] Example
[0032] This embodiment provides a laser rapid shovel calibrator, including an angle adjustment mechanism 100, a mark generation mechanism 200, and an optical projection lens 300. The angle adjustment mechanism 100 includes an angle adjustment component and a universal rotating connecting rod 107. The mark generation mechanism 200 is connected to one end of the angle adjustment mechanism 100 through the universal rotating connecting rod 107. The optical projection lens 300 is mounted on the mark generation mechanism 200.
[0033] Specifically, the laser rapid spade calibrator in this embodiment provides rapid and clear ground calibration for artillery spade pits. It consists of three interconnected modules: an angle adjustment mechanism 100, a marking generation mechanism 200, and an optical projection lens 300, and can be directly installed near the artillery carriage. The omnidirectional rotating connecting rod 107 in the angle adjustment mechanism 100 can be adjusted via an angle adjustment component. Since the omnidirectional rotating connecting rod 107 is connected to the marking generation mechanism 200, adjusting the angle of the marking generation mechanism 200 allows for angle adjustment of the marking generation mechanism 200. The marking generation mechanism 200 generates a laser beam conforming to the calibration shape, which is then projected onto the ground by the optical projection lens 300 to form a standard calibration area.
[0034] Preferably, the angle adjustment mechanism 100 includes a mounting plate 101, lateral support seats 102, adjusting nuts 103, an X-axis adjusting plate 104, a pressure plate 105, a Y-axis adjusting plate 106, and a rotating shaft 109. The two lateral support seats 102 are engaged on the mounting plate 101. The end of the lateral support seat 102 away from the mounting plate 101 is provided with a first shaft hole. The universal rotating connecting rod 107 is provided with a second shaft hole. The rotating shaft 109 passes through the first shaft hole and the second shaft hole. The end of the universal rotating connecting rod 107 near the mounting plate 101 is slidably connected to the Y-axis adjusting plate 106 and the X-axis adjusting plate 104. The adjusting nut 103 is rotatably connected above the Y-axis adjusting plate 106.
[0035] Specifically, the angle adjustment mechanism 100 is used to adjust the angle of the marking generation mechanism 200 to ensure that the laser projection area accurately covers the range of the shovel pit. Specifically, it includes a mounting plate 101 for fixed installation on the artillery carriage, two lateral support seats 102 screwed onto the mounting plate 101, and a universal rotating connecting rod 107 including a first connecting rod and a second connecting rod perpendicular to each other. The first connecting rod is horizontal and the second connecting rod is vertical. A second shaft hole is provided at the connection between the first connecting rod and the second connecting rod, and a first shaft hole is provided at the end of the lateral support seat 102. The universal rotating connecting rod 107 can rotate on the rotating shaft 109 by passing through the first shaft hole and the second shaft hole. The first connecting rod is away from the direction of the first shaft hole. The Y-axis adjusting plate 106 and the X-axis adjusting plate 104 are slidably connected to the first connecting rod. The Y-axis adjusting plate 106 is vertically and rotatably connected to the adjusting nut 103. Therefore, the position in the X direction can be adjusted by sliding the X-axis adjusting plate 104 on the first connecting rod, and the position of the Y-axis adjusting plate 106 in the Y-axis direction can be changed by rotating the adjusting nut 103. The two work together to achieve horizontal and vertical angle adjustment to ensure that the projection angle can be accurately aligned with the position of the excavation pit. The second connecting rod faces downwards and is threaded. Therefore, pitch and horizontal angle adjustments can be achieved through the universal rotating connecting rod 107, the Y-axis adjusting plate 106, and the X-axis adjusting plate 104.
[0036] Preferably, the angle adjustment mechanism 100 includes a limiting steel sleeve 108, which is disposed between the universal rotating connecting rod 107 and the lateral support seat 102 and sleeved on the rotating shaft 109. The limiting steel sleeve 108 can reduce the direct friction between the universal rotating connecting rod 107 and the lateral support seat 102, reduce wear, and at the same time ensure the coaxiality of the rotating shaft 109, avoiding shaking during adjustment.
[0037] Preferably, a pressure plate 105 is provided above the Y-axis adjustment plate 106, which can press the adjusting nut 103. The pressure plate 105 is threadedly connected to the top of the Y-axis adjustment plate 106. After the position of the adjusting nut 103 is adjusted, the screws of the pressure plate 105 are tightened to make the pressure plate 105 press tightly against the adjusting nut 103, preventing the adjusting nut 103 from loosening and affecting the projection angle.
[0038] Preferably, the marking generating mechanism 200 includes a housing, a support base 202, a laser heat sink 203, a laser tube mounting base 204, a laser tube 205, an optical fiber panel 206, and a projection lens mounting plate 207. The top of the housing is connected to a universal rotating connecting rod 107. The housing is assembled into a square frame by five housing mounting plates 201, thus creating an opening in the housing. The projection lens mounting plate 207 is installed at the opening. The support base 202 is installed inside the housing on the side corresponding to the projection lens mounting plate 207. The laser heat sink 203 is installed below the support base 202. The laser tube mounting base 204 is slidably connected inside the laser heat sink 203. The laser tube 205 is connected inside the laser tube mounting base 204 by adhesive. The optical fiber panel 206 is installed on the support base 202. The projection lens mounting plate 207 has mounting holes.
[0039] Specifically, the marking mechanism 200 is used for laser emission and converts the beam into a shape that meets calibration requirements. An outermost square housing protects the internal laser generator. The housing is threaded to a second connecting rod at the top, connecting the marking mechanism 200 to the angle adjustment mechanism 100. The housing consists of five housing mounting plates 201 connected by screws, leaving an opening which is sealed by a projection lens mounting plate 207. Inside the housing are a support base 202 and a laser heat sink 203, which are sequentially screwed onto the housing mounting plates 201 corresponding to the opening. A laser tube mounting base 204 is slidably connected to the laser heat sink 203 and secured with screws. The laser tube 205 is glued to the laser tube mounting base 204. The laser heat sink 203 prevents the laser tube 205 from overheating and being damaged or affecting operation. The fiber optic panel 206 is glued to the support base 202. The fiber optic panel 206 has a specific shape to shape the laser beam emitted by the laser tube 205.
[0040] The side of the fiber optic panel 206 closest to the laser tube 205 is the light-inlet side, which is the receiving end of the fiber optic bundle 209. It is connected to the fiber optic head 208 via fiber optic 210. The fiber optic head 208 needs to be precisely aligned with the light-outlet end of the laser tube 205. The laser tube 205 is fixed by the laser tube mounting base 204, which can slide back and forth along the sliding groove. By adjusting the sliding, the light-outlet end of the laser tube 205 can be aligned with the center position of the fiber optic head 208, ensuring that the laser beam emitted by the laser tube 205 can efficiently enter the fiber optic bundle 209. The other side of the fiber optic panel 206 is the light-emitting side, which is also the light-emitting end of the fiber optic bundle 209. It needs to be precisely aligned with the light-input end of the optical projection lens 300. The optical projection lens 300 is fixed to the opening of the front panel of the housing by the lens mount 310. The projection lens mounting plate 207 and the support base 202 are coaxial. Therefore, the light-emitting end of the fiber optic panel 206 and the light-input end of the optical projection lens 300 can be naturally aligned and arranged according to the size of 0.8*0.3m projected onto the ground by the optical projection lens 300. The projection of the optical projection lens 300 is object:image = 0.0365:1. The exported laser beam directly enters the optical projection lens 300 and is projected onto the ground to form a standard calibration area.
[0041] Preferably, the optical projection lens 300 is used to optimize the optical path and eliminate distortion. It is threaded into a mounting hole. The optical projection lens 300 includes a lens mount 310, pressure rings, lenses, and spacers. The lenses and spacers are spaced apart and embedded inside the lens mount 310, and pressure rings are provided at both ends of the lens mount 310 for locking and fixing. Specifically, the pressure rings include a first pressure ring 301 and a second pressure ring 309; the lenses include a first lens 302, a second lens 304, a third lens 306, and a fourth lens 308; and the spacers include a first spacer 303, a second spacer 305, and a third spacer 307. The spacers and lenses are sequentially installed inside the lens mount 310 in the order of first lens 302, first spacer 303, second lens 304, second spacer 305, third lens 306, third spacer 307, and fourth lens 308. The first pressure ring 301 and the second pressure ring 309 are fixed from both ends of the lens mount 310. The optical projection lens 300 can project the fiber optic panel 206 and display a clear pattern of 0.8*0.3 meters on the ground.
[0042] Brief description of working principle: The laser rapid shovel calibrator of this utility model is first fixed on the artillery carriage by the mounting plate 101 of the angle adjustment mechanism 100. Then, the laser tube 205 in the marking generation mechanism 200 is activated to emit a laser beam. This laser beam is projected to the receiving end of the fiber optic panel 206 on the support 202. The fiber optic bundles 209 arranged in a rectangular pattern in the fiber optic panel 206 will conduct the laser to the light output end to form a rectangular preliminary beam. Subsequently, the preliminary beam enters the optical projection lens 300 for projection. At the same time, the operator adjusts the angle of the device by using the universal rotating connecting rod 107, X-axis adjustment plate 104, Y-axis adjustment plate 106 and adjusting nut 103 of the angle adjustment mechanism 100 until it is at 41.5 degrees with the ground and the angle is locked by the pressure plate 105. Finally, the processed laser beam is accurately projected onto the ground to form a distortion-free and clear marking area with a length of 0.8 meters, a width of 0.3 meters and a line width of 20 mm. The operator can directly dig a shovel pit along the marking area to complete the rapid calibration.
[0043] Although the embodiments of this utility model have been described in the specification, these embodiments are merely illustrative and should not limit the scope of protection of this utility model. Various omissions, substitutions, and modifications made without departing from the spirit of this utility model should be included within the scope of protection of this utility model.
