Description

Technical Field

[0001] This invention relates to the field of weapon launching technology, specifically to a disc launcher and a disc launcher device. Background Technology

[0002] During the process of the launcher entering the water across the medium, it will "bounce" due to the resistance of the water surface. That is, the launcher cannot be fired in the final correct trajectory according to the preset launch trajectory, thus affecting the launch accuracy and causing a large deviation in the ballistics and data test results.

[0003] To address the aforementioned issues, Chinese invention patent CN113267099B, with an authorization announcement date of September 1, 2023, discloses a toothed disc-shaped rapid underwater launcher and a corresponding launch tube. This patent proposes an underwater launcher with a novel shape and a corresponding launch tube capable of rotating and launching the underwater launcher. The launch tube enables the underwater launcher to spin and enter the water at high speed, achieving a swirl-slide entry and stabilizing the trajectory of the cross-medium entry. Specifically, the disc-shaped underwater launcher has circumferentially extending toothed structures evenly arranged on its circumferential end face. The launcher contains a toothed structure similar to a rack extending along the launch direction. By placing the disc-shaped launcher in the launch tube during launch, the toothed structures mesh with the toothed structure inside the launch tube. When the gas inside the launch tube expands, it propels the launcher to move at high speed along the launch direction while maintaining engagement. After exiting the tube, the launcher can advance at high speed along a predetermined trajectory while simultaneously spinning around its axis, achieving the cross-medium entry requirement of a swirl-slide entry and preventing bouncing upon entry.

[0004] However, the dispenser in the aforementioned application has a disc-shaped structure, which is thicker in the middle and thinner at the outer periphery. This results in lower strength of the offset tooth structure after machining on the outer end face, making it prone to jamming and tooth breakage when the underwater dispenser engages and moves within the launch tube. Furthermore, because there is a step between the tooth root and tooth tip of the offset tooth structure, the gap will come into contact with the water surface during the dispenser's spiral entry into the water, causing significant resistance or water accumulation, which still leads to bouncing and affects the effectiveness of cross-medium water entry. Summary of the Invention

[0005] The purpose of this invention is to provide a disc launcher to solve the technical problem in the prior art where discs launched from launch tubes easily bounce upon entering the water, affecting the water entry effect. Furthermore, the purpose of this invention is also to provide a disc that reliably engages with the aforementioned disc launcher, simultaneously solving the above-mentioned problems.

[0006] To achieve the above objectives, the technical solution of the disc-shaped launching device provided by the present invention is as follows:

[0007] A disc-shaped launcher includes a launch tube with a longitudinally extending launch cavity. At least one elastic blocking element is provided on the cavity wall at a transverse interval. The elastic blocking element includes a stop for elastically engaging with a blocking groove eccentrically arranged on the side of the disc-shaped launcher, and an elastic device for driving the stop to slide into the blocking groove. A redirecting surface is provided on the stop to allow the stop to slide into and out of the blocking groove. The disc-shaped launcher has n eccentrically arranged blocking grooves, which are uniformly arranged around the axis of the disc-shaped launcher, where n ≥ 2. The spacing between the elastic blocking elements on the cavity wall matches 1 / n of the pitch circle of the blocking groove center.

[0008] Beneficial Effects: This invention addresses the problems existing in current launching devices by improving upon existing technology, creating an improved invention. By arranging elastic blocking elements longitudinally spaced on at least one of the longitudinally opposite cavity walls of the disc-shaped launching device, the engagement structure used to impede the disc-shaped body's spin within the launching cavity is transferred from the conventional outer peripheral end of the disc-shaped body to its side surface. This creates a locking and blocking effect on the eccentric side of the disc-shaped body in the direction perpendicular to its travel. The elastic blocking elements can slide into the blocking groove via an elastic device and subsequently disengage from the blocking groove via a redirecting surface. The redirecting surface acts as a locking mechanism, providing tangential force for the disc-shaped body's rotation. Furthermore, the redirecting surface guides the stop head into and out of the blocking groove. This allows the disc-shaped body to rotate around the elastic blocking elements using centrifugal force, thus generating spin during its travel. There is no need to process the low-strength, water-entry-effect-affecting offset teeth on the outer peripheral end face of the disc rotor, nor is there a need to set up a rack structure that meshes with the offset teeth. The entire outer periphery of the disc rotor is a cutting edge, which facilitates water entry and ensures strength, thus solving the technical problem of disc rotor bouncing upon entering the water.

[0009] Preferably, the elastic blocking element is provided on both transversely spaced cavity walls of the transmitting tube, and the two transversely opposite elastic blocking elements are symmetrically arranged. The symmetrical elastic blocking elements enhance the blocking effect on the disc-shaped body and limit the disc-shaped body from both sides, making the movement of the disc-shaped body more stable and preventing tilting.

[0010] Preferably, the elastic device includes a spring that presses against one end of the stop. The spring pressing against one end of the stop provides a stable and reliable elastic force to the stop.

[0011] Preferably, the elastic blocking element includes a base for fixed connection with the side wall, a stop for elastically engaging with the blocking groove, and a compression spring press-fitted between the base and the stop. The base serves as a fixed connection, maintaining a secure connection with the cavity wall. The stop is elastically assembled via the compression spring, with the fixed and elastic components working in tandem to ensure both the overall connection strength of the elastic blocking element and its elastic effect.

[0012] Preferably, the cavity wall is provided with a through hole for the elastic retaining element to extend into, and the base flange is connected to the opening of the through hole. The flange connection is reliable and can be disassembled, and the through hole facilitates insertion and removal.

[0013] Preferably, a maintenance plate is detachably connected to one end of the transmitting tube. The maintenance plate facilitates timely observation, repair, and replacement of the internal structure of the transmitting tube.

[0014] Preferably, the redirecting surface is formed by a chamfer provided on the stop. The chamfered redirecting surface has a smooth fit, preventing damage to the tip or scratches to the disc.

[0015] Preferably, the launching tube includes mating launching tube sidewalls that are detachably connected, forming the launching cavity. The detachable connection of the launching tube sidewalls also facilitates the arrangement of the internal structure and subsequent maintenance.

[0016] Preferably, one end of the launching tube is connected to a high-pressure venting line, and pressure sensors are installed on both the high-pressure venting line and the cavity wall of the launching tube. The presence of pressure sensors on both the high-pressure venting line and the cavity wall of the launching tube facilitates pressure monitoring and allows for convenient control of the launch speed.

[0017] The technical solution of the disc-shaped body provided by this invention is as follows:

[0018] A disc-shaped body includes a disc-shaped disk body. The side surface of the disc-shaped body is eccentrically provided with blocking grooves in the same circumferential direction. There are n blocking grooves eccentrically arranged on the side surface of the disc-shaped body. The n blocking grooves are evenly arranged around the axis of the disc-shaped body, and n≥2. The spacing between the elastic blocking elements on the cavity wall matches 1 / n of the pitch circle of the center of the blocking groove.

[0019] Beneficial Effects: This invention addresses the problems existing in current launching devices by improving upon existing technology, creating an improved invention. By modifying the disc-shaped body and machining retardation grooves on its sides, with each groove evenly arranged around the disc-shaped body's axis, it eliminates the need to machine the thinner outer periphery of the disc-shaped body. This ensures the integrity and structural strength of the outer periphery of the disc-shaped body, which forms the cutting edge when it slides into the water. The lateral retardation grooves and the launching device work together to generate spin, allowing it to slide into the water without bouncing. This effectively solves the technical problem in existing technologies where disc-shaped bodies easily bounce upon entering the water, affecting the water entry effect. Attached Figure Description

[0028] The purpose of this invention is to provide a disc-shaped object and a disc-shaped object launching device capable of launching the disc-shaped object. Based on the problems existing in the existing dispensers and their launching tubes, the invention transfers the "engagement" of the disc-shaped object to the side plate of the disc-shaped object, thereby increasing the strength of the engagement structure and the integrity of the cutting edge, and preventing water bounce.

[0029] The present invention will be further described in detail below with reference to embodiments.

[0030] Specific embodiment 1 of the disc-shaped launcher provided by the present invention:

[0031] like Figures 1 to 3 As shown, the disc-shaped launch device in this embodiment includes two mounting brackets 11 installed in a test site or launch site, and a launch tube supported and fixed on the two mounting brackets 11. One end of the launch tube is open as a launch port, located at... Figure 1 On the left side, a maintenance plate 4 is detachably connected to the other end. Maintenance plate 4 encloses and connects to the launch power system, located at... Figure 1 Right side. In this embodiment, the disc-shaped launcher is used by inserting the disc-shaped body 3 into the rightmost longitudinal end of the launch tube, and then starting the launch power system to achieve the rotational launch of the disc-shaped body 3 to the left. Wherein, as... Figure 2As shown, in this embodiment, the transmitting tube is composed of two transmitting tube sidewalls 1 fastened together. Both transmitting tube sidewalls 1 are longitudinally extending T-shaped plate structures. The outer end face of the long side of the T-shaped plate is provided with opposing arc-shaped grooves. When the outer end face of the long side of the T-shaped plate is as shown... Figure 2 and Figure 3 When the two mating arc-shaped grooves are joined, they form a launch cavity 17 that fits the disc-shaped body 3 with a clearance, allowing the disc-shaped body 3 to move longitudinally. In other embodiments, a maintenance plate may not be required, and the launch power system may be directly connected to one end of the launch tube.

[0032] In this embodiment, as Figure 1 As shown, after the two launch tube sidewalls 1 are joined together, the T-shaped flanges at the upper and lower ends of the two launch tube sidewalls 1 are locked and fixed by a horizontally evenly distributed bolt and nut assembly, forming a launch tube stably installed on the mounting bracket 11. In other embodiments, the launch tube can also be a box-type structure or a trough-shaped or cylindrical structure, with its sidewalls being detachable and a disc-shaped launch cavity 17 machined inside. Alternatively, the launch tube sidewalls 1 are integrally formed and cannot be disassembled, and the disc-shaped launch body 3 is launched through the top or side opening.

[0033] In this embodiment, both emitter tubes have longitudinally spaced elastic blocking elements 2 on their sidewalls 1, so as to... Figure 1 Taking the elastic blocking element 2 on the side wall 1 of the launch tube arranged in the middle as an example, in this embodiment, the elastic blocking element 2 is located below the longitudinal centerline of the launch cavity 17, so that the elastic blocking element 2 can elastically slide into and out of the blocking groove 16 on the disc 3, realizing the driving rotation after blocking, realizing the application of centrifugal force on the high-speed moving disc 3, and thus causing the disc 3 to generate spin during its movement in the launch cavity 17. In this embodiment, as shown in the example... Figure 1 and Figure 2 As shown, since the elastic blocking element 2 is located below the longitudinal centerline of the emission cavity 17, the elastic blocking element 2 provides a blocking engagement on the lower half of the disc surface of the disc body 3. Figure 1 In some embodiments, the resilient stop can rotate counterclockwise when moving to the left. Alternatively, the resilient stop can be positioned above the longitudinal centerline of the launch tube sidewall, corresponding to the upper half of the disc surface. In this case, when the disc is launched to the left, it rotates clockwise.

[0034] like Figure 1 and Figure 3As shown, in order to fix the elastic blocking element 2 on the side wall 1 of the launch tube, the side wall 1 of the launch tube in this embodiment is provided with longitudinally uniformly spaced perforations 12. Each elastic blocking element 2 passes through the perforation 12 from the outside of the launch tube into the launch cavity 17. The elastic blocking element 2 in this embodiment includes a base 13 for fixing to the cavity wall and a stop 15 elastically connected to the base 13. The stop 15 and the base 13 are elastically assembled by an elastic device. The base 13 can ensure the fitting strength with the side wall of the launch tube, and the stop 15 can block the disc 3. Specifically, one end of the base 13 in this embodiment is provided with a connecting flange. The connecting flange is used to connect with the orifice flange of the perforation 12 after the stop 15 passes through the perforation 12 to ensure the connection strength. In other embodiments, the elastic blocking element can also be an integral block or column structure. In this case, the elastic device can be set between the side wall of the launch tube and the elastic blocking element.

[0035] In this embodiment, as Figure 3 As shown, the stop head 15 is a laterally extending cylindrical structure. The stop head 15 and the base 13 are elastically connected by an elastic device, allowing the stop head 15 to slide into and out of the blocking groove 16 on the disc-shaped body 3. In this embodiment, the elastic device is specifically a compression spring fixed between the base 13 and the stop head 15. The compression spring can contract under force when the stop head 15 and the disc-shaped body 3 are in a top-pressing engagement, ensuring that the disc-shaped body 3 can hook and engage with the stop head 15 to generate self-spinning. At the same time, by adjusting the elastic force and length of the spring 14, as well as the distance between the stop head 15 and the base 13, the extension length of the stop head 15, and the length of the base 13, the extension distance of the elastic blocking element 2 can be adjusted, affecting the blocking effect of the elastic blocking element 2 on the disc-shaped body 3, that is, adjusting the driving force applied to the disc-shaped body 3, thereby controlling the rotational speed of the disc-shaped body 3. In other embodiments, the elastic device can also be a tension spring, an elastic column, or an elastic pressure block, etc.

[0036] In this embodiment, the stop head 15 has a redirecting surface that blocks and disengages from the blocking groove 16 on the disc-shaped body 3 when it slides in and out. The stop head 15 is cylindrical, with a rounded chamfer at its front end, which forms the redirecting surface. The redirecting surface guides the stop head into and out of the blocking groove. In other embodiments, the redirecting surface at the end of the stop head can also be a spherical conical surface, an arc surface, or an untreated planar structure.

[0037] like Figure 2 and Figure 3As shown, in this embodiment, elastic blocking elements 2 are provided on the sidewalls 1 of both launch tubes. The two rows of elastic blocking elements 2 in the longitudinal direction are parallel to each other and arranged at the same height. The elastic blocking elements 2 in the transverse direction are arranged symmetrically in pairs. Thus, when the disc-shaped body 3 is launched, the blocking grooves 16 on both sides of its disc are simultaneously blocked by two elastic blocking elements 2, ensuring both a stable supply of rotational driving force and preventing the disc-shaped body 3 from tilting. In other embodiments, the elastic blocking elements on the sidewalls of the two launch tubes can be arranged alternately. Alternatively, in other different embodiments, transversely spaced elastic blocking elements can be arranged on only one sidewall 1 of the launch tube.

[0038] The process of using the disc-shaped launcher in this embodiment is as follows: Figure 1 As shown, first lock the launch tube on the mounting bracket 11, determine the launch angle, and check the installation of each elastic retardant 2. During this process, the inspection plate 4 can be opened, and lubricating grease can be applied to the cavity wall of the launch chamber 17. Then, the disc body 3 is installed into the right side of the launch chamber 17, close to the launch power system on the right side, so that the retardation groove 16 on the disc body 3 elastically engages with the stop 15 of the elastic retardant 2 in the perforation 12 of the side wall 1 of the launch tube.

[0039] When the disc-shaped body 3 is launched, the launch power system is activated, and the disc-shaped body 3 moves longitudinally under pressure. Simultaneously, under the locking action of the elastic restraints 2 on both sides of the launch tube, centrifugal force is used to drive synchronous spin, achieving high-speed rotation of the disc-shaped body 3 before it exits the launch tube. After the experiment, the data will be analyzed further.

[0040] Specific embodiment 2 of the disc-shaped launcher provided by the present invention:

[0041] This embodiment is a further improvement on embodiment 1, such as... Figure 1 As shown, the launch power system includes a high-pressure ventilation pipeline connected to the right side of the launch tube, and also includes a rupture disc and its holder 6, a pressure sensor 7, a solenoid valve 8, a pressure gauge 9, and a gas source 10 connected in sequence on the high-pressure ventilation pipeline.

[0042] When the disc-shaped body 3 is launched, the pressure sensor 7 is activated to collect data first, then the gas source 10 is turned on and the solenoid valve 8 is opened. The rupture disc in the holder breaks under the action of high pressure gas, and the high pressure gas rushes into the right end of the launch tube. The disc-shaped body 3 moves to the left under the pressure of the gas. After the test, the data is combined for subsequent analysis.

[0043] In this embodiment, a pressure sensor 7 is also provided on the cavity wall of the launch tube to cooperate with the pressure sensor 7 on the high-pressure ventilation pipeline to more accurately regulate the spin and pressure.

[0044] Of course, in other embodiments, the structure of the launch power system can be changed, for example, it can be directly set as a jet structure or a gas compression structure such as an air compressor.

[0045] Specific embodiments of the disc-shaped spiral body provided by the present invention:

[0046] The present invention also provides a disc-shaped body, thereby enabling the disc-shaped body 3 to be arranged and used in the disc-shaped body launching devices of the above embodiments, such as... Figures 4 to 6 As shown, similar to the disc-shaped body 3 in the prior art, the disc-shaped body 3 in this embodiment is a disc structure that is circular when viewed from the front and disc-shaped when viewed from the side. The difference is that the disc-shaped body 3 in this application does not require machining of its outer peripheral end face. Instead, it has blocking grooves 16 on the outer peripheral curved surface spaced apart from the outer peripheral end, for engaging with the elastic blocking elements 2 on the wall of the launching tube. Each blocking groove 16 is eccentrically arranged and located on the same circumference. Specifically, there are five blocking grooves 16, centered on the disc's center point and pointing upwards on the same circumference, dividing the circumference evenly. When arranging the disc-shaped launching device, the spacing of the perforations 12 is 1 / 5 of the center pitch circle of the elastic blocking elements 2. Furthermore, since corresponding elastic blocking elements 2 are provided on the side walls 1 of both launching tubes, corresponding blocking grooves 16 are provided on both curved surfaces of the disc-shaped body 3 in this embodiment. The blocking grooves 16 can better "mesh" with the elastic blocking elements 2, achieving stable and reliable rotation of the disc-shaped body 3.

[0047] In this invention, n eccentrically arranged blocking grooves are provided on the side of the disc-shaped body. These n blocking grooves are evenly distributed around the axis of the disc-shaped body, where n ≥ 2. The spacing between the elastic blocking elements on the cavity wall matches 1 / n of the pitch circle of the blocking groove center. For example, in the above embodiment, there are 5 blocking grooves, each shaped like a near-isosceles triangle. The apex of each isosceles triangle faces the center of the disc-shaped body, and the spacing between the corresponding elastic blocking elements matches 1 / 5 of the pitch circle of the blocking groove center. In other embodiments, to facilitate the processing of the blocking grooves, opposing blocking grooves on two curved surfaces can be directly connected. Alternatively, the shape of the blocking grooves can be adjusted to different groove structures such as fan-shaped rings, triangles, or circles, depending on the fit with the elastic blocking elements. In other embodiments, the number n of blocking grooves on the disc-shaped body surface can be increased or decreased according to the fit, for example, by setting 3 or increasing to 6.

[0048] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still make modifications to the technical solutions described in the foregoing embodiments without creative effort, or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
