Description

Technical Field

[0001] The invention relates to the technical field of underwater unmanned aerial vehicle launching, and in particular to a deceleration and anti-recoil resistance device used in complex water conditions. Background Art

[0002] Underwater anchored launchers and other underwater pre-placed platforms have the advantages of strong concealment, extremely fast response, relatively low cost, and adaptability to a variety of launch loads. In order to ensure that the pre-placed platform can quickly perform tasks, it generally relies on its own positive buoyancy and will not go out of the water too quickly when floating in shallow water areas. Once it enters the near sea or deep sea, when the vertical speed of the pre-placed platform reaches saturation, the pre-placed platform will go out of the water as a whole. When it is submerged in the water, the repeated process of entering and exiting the water increases the adjustment time of the water surface and affects the launch timing, which is contrary to the concealment and rapid response of the pre-placed platform.

[0003] In addition, when launching at a higher launch altitude or with a heavier payload, the equipment is prone to water ingress, which can lead to launch failures and other problems. Therefore, effectively maintaining the posture of the launch platform out of the water, avoiding repeated water ingress and egress of the pre-set platform, increasing the water surface adjustment time, delaying the launch timing, and achieving successful launch in complex water conditions have become research focuses. Therefore, a low-cost, high-reliability deceleration anti-recoil resistance device is needed for launching on the water surface in complex water conditions. Summary of the invention

The vent bolt is used to balance the internal and external pressure difference of the installation component and to perform an air tightness check. The switch button is used to control the resetting and starting and stopping of the electrical components in the installation component.

[0009] The deceleration assembly also includes a ball bolt, the side of the unlocking iron plate close to the electromagnet is a plane, and the side close to the wing is a spherical surface. The unlocking iron plate is connected to the wing through the ball bolt, so that the unlocking iron plate can rotate on the surface of the wing and fit tightly with the surface of the electromagnet.

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0022] like Figures 1 to 10 As described above, the embodiment of the present invention provides a deceleration and anti-recoil resistance device for complex water conditions, including: an unlocking component 11, a mounting component 12 and a deceleration component 13.

[0023] Specifically, Figures 1 to 5 As shown, in this embodiment, a plurality of symmetrically distributed electromagnets 115 are disposed on the periphery of the unlocking component 11, the mounting component 12 is fixedly disposed at the bottom of the unlocking component 11, and a deceleration component 13 is disposed on the periphery of the mounting component 12 at positions corresponding to the electromagnets 115.

[0024] Specifically, Figures 6-8 As shown, the deceleration assembly 13 includes a swing rod 132, a wing 131, an unlocking iron plate 133, and an unfolding spring 135; the swing rod 132 is rotatably set at the bottom of the mounting assembly 12 through a rotating shaft 136, the wing 131 is fixed on the inner side of the swing rod 132, the unlocking iron plate 133 is set on the inner side of the wing 131, and corresponds to the position of the electromagnet 115, and is used to be attracted by the electromagnet 115; the unfolding spring 135 is fixed on the inner side of the wing 131, and is used to push the wing 131 to unfold when the unlocking iron plate 133 and the electromagnet 115 are released from attraction.

[0025] Specifically, in this embodiment, the rotating shaft 136 is a cylindrical pin, and further, the rotating shaft 136 is a double-ended internally threaded cylindrical pin. Figure 1 and 3 As shown, the unlocking assembly 11 is provided with a plurality of compression grooves 116 , and the compression grooves 116 are located directly above the electromagnet 115 , and the compression grooves 116 are used to place the expansion springs 135 .

[0026] Furthermore, if Figure 3 As shown, in this embodiment, a cylindrical hole is further provided on the cylindrical side surface of the unlocking component 11. Specifically, two cylindrical holes are provided between every two electromagnets. The cylindrical holes have the function of reducing weight on the one hand, and on the other hand, round rods can be inserted to facilitate the disassembly and assembly of the unlocking component 11.

[0027] Specifically, Figures 4 and 5 As shown, in this embodiment, a receiving space for receiving an electrical component is provided at the center above the mounting assembly 12, and a first sealing ring 111 is provided at the connection position between the mounting assembly 12 and the unlocking assembly 11 to seal the electrical component. Specifically, the mounting assembly 12 and the unlocking assembly 11 are sealed by a piston and fixed by a plurality of radial countersunk bolts 117.

[0028] Furthermore, if Figure 4 As shown, in this embodiment, the electrical component includes a six-axis gyroscope 128, a main control circuit board 126, and a relay. The electrical component is arranged in the installation component 12 through an electrical control module fixing plate 125. Specifically, the electrical control module fixing plate 125 is fixed in the installation component 12 by bolts, the six-axis gyroscope 128 is fixed on the electrical control module fixing plate 125, the relay is arranged above the six-axis gyroscope 128, and the main control circuit board 126 is arranged above the relay. The main control circuit board 126 is used to control the working state of each electromagnet 115. Specifically, the control module on the main control circuit board 126 controls the working state of each electromagnet 115 through a relay.

[0029] Furthermore, if Figure 5 As shown, in this embodiment, a vent bolt 122, a depth gauge 123, and a switch button 124 are provided at the bottom of the mounting assembly 12. The vent bolt 122 is used to balance the internal and external pressure difference of the mounting assembly 12 and to check the air tightness. The vent bolt 122 is unscrewed to ventilate the inside and outside of the mounting assembly 12, which is convenient for installation and removal. In addition, a dedicated air pump can also be used to test the sealing inside the device through the vent bolt. There are two switch buttons 124, which are used to control the reset and start and stop of the electrical components in the mounting assembly 2. Specifically, the switch button 124 can be a rotary switch; the depth gauge 123 is used to detect the depth of the device.

[0030] like Figures 6-8 As shown, in this embodiment, the deceleration assembly 13 is fixed to the mounting assembly 12 by a rotating shaft 136 and rotates around the rotating shaft 136. In order to solve the error caused by the rotation and make the unlocking iron plate 133 and the electromagnet 115 fully attracted, it is necessary to make the angle of the unlocking iron plate 133 adjustable. Specifically, in this embodiment, the deceleration assembly 13 also includes a ball stud 134. The side of the unlocking iron plate 133 close to the electromagnet 115 is a plane, and the side close to the wing 131 is a spherical surface. The unlocking iron plate 133 is connected to the wing 131 by the ball stud 134, so that the unlocking iron plate 133 can rotate freely on the inner surface of the wing 131 and thus fit tightly with the surface of the electromagnet 115.

[0031] Specifically, the surface of the unlocking iron plate 133 in contact with the ball stud 134 is an arc surface, so when the unlocking iron plate 133 rotates, the surface of the center hole inside it rotates relative to the spherical surface of the ball stud 134, and the spherical surface on the outside close to the wing 131 rotates relative to the inner surface of the wing 131. Therefore, the unlocking iron plate 133 can automatically roll around the ball stud 134 to achieve a better fit with the electromagnet 115. In addition, a slot is processed on the ball stud 134 to facilitate installation.

[0032] Specifically, in this embodiment, the wing 131 is obtained by wire cutting of an aluminum alloy tube, the inner diameter of the aluminum alloy tube is the same as the outer diameter of the unlocking assembly 11 and the installation assembly 12, and the outer diameter is the same as the outer diameter of the pre-set platform 20. The wing 131 is connected to the swing rod 132 by a semi-countsunk bolt.

[0033] Furthermore, if Figure 4 As shown, in this embodiment, the mounting assembly 12 is provided with a rotation groove 120 for mounting each deceleration assembly 13, and the rotation shaft 136 is disposed in the rotation groove 120. A clamping column 121 is disposed above the rotation groove 120, and the clamping column 121 is connected to the mounting assembly 12 via a limit spring 129. Figure 8 As shown, the swing lever 132 is provided with a limit slot 138; the limit slot 138 is used to cooperate with the clamping column 121 to limit the wing 131 when the wing 131 is unfolded. When the wing 131 is folded, the swing lever 132 squeezes the clamping column 121 and the limit spring 129 so that they are located in the groove inside the mounting assembly 12, as shown in FIG. Figures 9 and 10 As shown, when the wing 131 is fully unfolded, the limit slot 138 on the swing rod 132 is aligned with the position of the clamping column 121. Under the elastic force of the limit spring 129, the clamping column 121 extends out and is clamped in the limit slot 138, so that the wing 131 remains in the unfolded state.

[0034] In this embodiment, an upwardly protruding anisotropic cylindrical portion is provided inside the installation component 12 , and the portion is used to provide a groove for installing the limit spring 129 and the clamping column 121 .

[0035] Furthermore, if Figures 4 and 5 As shown, a long strip-shaped reset hole 127 is provided on the side of the mounting assembly 12, and the reset hole 127 is used to reset the clamping column 121, thereby resetting and folding the wing 131. Specifically, a reset bolt 139 is provided on the clamping column 121. When the wing 131 needs to be reset after being unfolded, the limit spring 129 can be compressed upward to a recovery state by aligning the reset bolt 139 with a screwdriver, and then the clamping column 121 moves upward and disengages from the limit clamping slot 138. The swing rod 132 can be manually lifted 90 degrees to complete the recovery. It can be reused without disassembly, and does not rely on any explosives or other pyrotechnics, thereby increasing the safety of the test.

[0036] Furthermore, if Figure 2~3 As shown, in this embodiment, the unlocking assembly 11 is provided with a plurality of mounting grooves, and each of the electromagnets 115 is respectively provided in one of the mounting grooves, and is sealed by a sealing flange 112, a thin iron sheet 113, and a second sealing ring 114. Specifically, the electromagnet 115 is provided in the mounting groove, and a second sealing ring 114, a thin iron sheet 113, and a sealing flange 112 are sequentially provided on its surface. The sealing flange 112 is fixedly connected to the unlocking assembly 11 by bolts to achieve a large-depth underwater sealing of the electromagnet 115. The magnetism of the electromagnet 115 is transmitted through the thin iron sheet 113. When the deceleration assembly 13 is folded, the unlocking iron plate 133 is tightly attracted to the thin iron sheet 113 to keep the deceleration assembly 13 in a folded state.

[0037] In this embodiment, the space in the upper center of the unlocking assembly 11 can be used to place electrical components such as the power supply and wires of the deceleration anti-recoil device.

[0038] Furthermore, if Figure 6 As shown, in this embodiment, a spring stopper 140 is fixedly arranged at the end of the deployment spring 135, and the spring stopper 140 is fixedly connected to the swing rod 132 by a bolt. By arranging the deployment spring 135 on the swing rod 132, it can be ensured that the spring is perpendicular to the axis of the wing 131, providing the fastest deployment speed for the operation of the device. In addition, the unlocking iron plate 133 is also arranged at a position corresponding to the swing rod 132, and is connected to the wing 131 and the swing rod 132 by a ball stud 134.

[0039] Specifically, the number of the deceleration components 13 is 4, and the central angle of each wing 131 is 90 degrees. In addition, the number can also be set to 3 to 6 as needed.

[0040] The working principle of this embodiment is as follows: when the deceleration assembly 13 is in the retracted folding state, the unfolding spring 135 is in a compressed state, and the unlocking iron plate 133 can fit tightly with the electromagnet 115 according to its own spherical surface and the ball head bolt 134, and maintain the folding state under the suction force generated by the electromagnet; when the deceleration assembly needs to be unfolded, the electromagnet 115 is energized to eliminate the magnetic force, and the wing 131 is unfolded under the elastic force of the compressed unfolding spring 135; the clamping column 121 is also subjected to the force released by the limit spring 129 and then bounces into the preset limit clamping groove 138 of the swing rod 132 to limit the swing rod 132. Among them, the electromagnet 115 uses a de-energized electromagnet, which eliminates the magnetic force when energized and restores the magnetic force when de-energized.

[0041] Specifically, Fig.11 As shown, the deceleration anti-recoil resistance device 10 in this embodiment is arranged at the tail of the preset platform 20 to act as a fixed rudder. The shape of the swing rod 132 can be adjusted according to the specific size of the preset platform 20, and then the rudder angle can be adjusted to improve the movement stability of the preset platform. Therefore, the deceleration anti-recoil resistance device in the embodiment of the present invention has the characteristic of strong adaptability.

[0042] The deceleration recoil resistance device of the present invention can provide two technical effects for the existing preset platform 20 .

[0043] The first type: Fig.12 As shown, when the pre-placed platform 20 needs to intervene quickly and shorten the time of adjusting the water surface, the main control circuit board 126 can collect depth data through the depth gauge 123 of the anti-recoil resistance device. When the depth is close to the water surface, the main control circuit board 126 is used to control the relay to energize and demagnetize the electromagnet 115, and the elastic force of the unfolding spring 135 will fully pop open the wing 131. The clamping column 121 is subject to the elastic force of the limit spring 129 to limit the deceleration component 13, so as to achieve the stable deployment of the deceleration component 13, and then provide resistance for the pre-placed platform 20 during the floating process, decelerate it, and make it leak out of the water at a suitable speed to launch the mission load, avoid repeated water in and out of the water, and improve the concealment of the pre-placed platform. During the launch, the unfolded deceleration component 13 can provide a great anti-recoil resistance for the pre-placed platform, and prevent the excessive recoil during the launch process from causing water to enter the mouth of the pre-placed platform, affecting the success rate of the launch. At the same time, the deceleration recoil resistance device of this embodiment can further lower the center of gravity of the preset platform 20, and can improve the stability of the water surface when floating on the water surface.

[0044] The second type: Fig.13As shown, when the pre-set platform 20 needs to be launched on a water surface with complex water conditions, the pre-set platform 20 will form an angle with the vertical line of the horizontal plane along with the waves. The main control circuit board 126 can collect the angle of the pre-set platform 20 in real time according to the six-axis gyroscope 128 in the deceleration anti-recoil resistance device 10. According to the actual angle of the pre-set platform and the launch requirement, the main control circuit board 126 can control the relay to energize and demagnetize the electromagnet 115 that needs to work, so that the corresponding wing 131 is unfolded. Specifically, as shown in FIG. Fig.13 As shown in (a), (b), and (c), one, two, or three of the fins can be deployed to quickly adjust the angle of the preset platform in real time, thereby improving the launch success rate in complex water conditions.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
