Abstract
Description
Technical Field
[0001] This disclosure generally relates to the field of rocket launch unlocking devices, and specifically to a rocket and launch pad unlocking device. Background Technology
[0002] During rocket launch, securing the rocket to the launch pad is a crucial step in ensuring launch safety. Traditional unlocking devices typically employ mechanical or electric unlocking methods. For example, separation of the rocket from the launch pad is achieved manually, or mechanical unlocking devices involve manually rotating or pushing the unlocking handle. Electric unlocking devices, on the other hand, use an electric cylinder to drive the unlocking mechanism. Compared to mechanical unlocking, electric unlocking offers improved automation and can shorten unlocking time to some extent. However, over long-term use, issues such as the sealing of the electric cylinder and the stability of the electrical circuitry have gradually emerged. These factors not only affect the normal operation of the unlocking device but may also cause malfunctions during rocket launch. Therefore, there is still room for improvement in the structural reliability and safety of current unlocking devices. Utility Model Content

Detailed Implementation
[0030] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.
[0031] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.
[0032] Example 1
[0033] Please refer to Figure 1 The diagram shown is a front view of a rocket-launch pad unlocking device provided in this embodiment. This unlocking device is used to conveniently and reliably unlock the rocket from the launch pad, allowing the rocket to take off smoothly from the launch pad. The unlocking device includes:
[0034] Locking assembly 1 is disposed at launch pad 02, which is used to fix the rocket to be launched. The top of the locking assembly 1 has a locking part, which has a first working state and a second working state. In the first working state, the locking part is locked with the connecting part 01 of the rocket to be launched. In the second working state, the locking part is separated from the connecting part 01 of the rocket to be launched to unlock and release the rocket to be launched.
[0035] Drive component 2 is connected to locking component 1 via a transmission. Drive component 2 is used to drive the locking part to switch between a first working state and a second state.
[0036] Control component 3 is connected to drive component 2 by signals. Control component 3 is used to control drive component 2 to execute running instructions. The running instructions include at least: start instructions and stop instructions.
[0037] In this embodiment, the locking assembly 1 is a key component for locking the rocket to be launched onto the launch pad 02. The locking assembly 1 locks the connecting portion 01 of the rocket to be launched via a locking part located at its top. See [link to details]. Figure 2 As shown in the structure, the connecting part 01 can be a locking bolt. The bottom of the locking bolt is screw-shaped and can be fixed with the locking part, thereby realizing the connection and fixation of the launch pad 02 and the rocket to be launched before launch. At this time, the locking part is in the first working state. When the control component 3 receives the rocket launch command, it will send a start command to the drive component 2. After responding to the start command, the drive component 2 can drive the locking part to switch from the first working state to the second working state. The locking part loosens the fixation to the connecting part 01, the launch pad 02 and the rocket to be launched separate, and the rocket to be launched enters the launch state.
[0038] As can be seen, under the operating command issued by the control component 3, the drive component 2 can accurately drive the locking part to switch between the first working state and the second working state, replacing the traditional manual operation, greatly improving the accuracy and automation level of the operation, and reducing the risk of rocket and launch mission safety being threatened by unlocking device failure during the launch process.
[0039] In a preferred embodiment, the unlocking device further includes: a connecting frame 4, which is connected to the launch pad 02 via a fixing lug 5 and is correspondingly arranged with the connecting part 01 of the rocket to be launched; and a locking assembly 1 is slidably arranged on the top of the connecting frame 4.
[0040] The connecting frame 4 provides installation space for components such as the locking assembly 1 and the drive assembly 2. The connecting frame 4 is detachably connected to the designated position of the launch pad 02 via the fixing lug 5. The designated position is determined based on the position of the rocket to be launched, and it is necessary to ensure that the locking assembly 1 and the connecting part 01 correspond and can be locked together.
[0041] In a preferred embodiment, see Figure 3 The locking assembly 1 includes:
[0042] A slide rail 6 is provided on the top of the connecting frame 4, and the slide rail 6 extends along the length of the connecting frame 4; at least two sliders 7 are slidably provided on the slide rail 6, and a transverse locking block 8 is fixedly connected to each slider 7, and the two transverse locking blocks 8 form a locking part.
[0043] Specifically, the top of the connecting frame 4 is provided with a slide rail 6 extending along the length direction of the connecting frame 4, the length direction being referenced to... Figure 1The horizontal direction also indicates that the locking part moves along this horizontal direction; the slide rail 6 is provided with two sliders 7 that can slide relative to each other, and each slider 7 is provided with a transverse locking block 8. With the support of the sliders 7, the transverse locking blocks 8 can move in a direction that is closer to each other or further away from each other. The two transverse locking blocks 8 are the locking parts. When the two transverse locking blocks 8 are in contact, it is the first working state. When the two transverse locking blocks 8 move from contact to further away from each other, it is the process of switching from the first working state to the second working state. When the two transverse locking blocks 8 are separated, it is the second working state.
[0044] In a preferred embodiment, see Figure 6 On the opposite edge of each of the two transverse locking blocks 8, there are semi-circular through holes 81 respectively; on the opposite side of the two transverse locking blocks 8, there are also grooves 82, which are connected to the corresponding semi-circular through holes 81. The cross-sectional width of the groove 82 in the first direction is greater than the radius of the semi-circular through hole 81. When the two transverse locking blocks 8 are close to each other, the two semi-circular through holes 81 and the two grooves 82 are respectively connected to each other to form a locking space for locking the connecting part 01.
[0045] Specifically, regarding the locking of the connecting part 01 by the two transverse locking blocks 8, it relies on the locking space jointly formed by the two transverse locking blocks 8. When the two transverse locking blocks 8 are close together, the semi-circular through hole 81 forms a circular hole through which the connecting part 01 can pass. The connecting part 01 can extend into the two grooves 82 below through the two semi-circular through holes 81 to form a communicating space. Since the connecting part 01 is screw-shaped, the diameter of the head of the connecting part 01 is larger and the rod is thinner. In order to securely lock the connecting part 01, the circular hole formed by the two semi-circular through holes 81 must match the diameter of the rod, and the space formed by the two grooves 82 must match the diameter of the head, so that the connecting part 01 will not come out between the two transverse locking blocks 8. At the same time, this also means that in the actual locking process, it is necessary to first confirm the position of the connecting part 01, and then drive the two transverse locking blocks 8 to move towards the connecting part 01 to form a locking of the connecting part 01.
[0046] In a preferred embodiment, see Figure 5 Driver component 2 includes:
[0047] Motor 9 is connected to a screw, and a push nut 10 is threaded onto the screw. A connecting rod 11 is slidably connected to each end of the push nut 10. The other end of the connecting rod 11 is slidably connected to the transverse locking block 8.
[0048] When the motor 9 drives the push nut 10 to move in the first direction, the push nut 10 can drive the connecting rod 11 to move, so that the two transverse locking blocks 8 move closer to each other or further away from each other, realizing the switching of the locking part between the first working state and the second working state.
[0049] Specifically, the drive assembly 2 is the power source of the entire unlocking device. The drive assembly 2 is connected to the lower part of the connecting frame 4 through the mounting frame 14. The drive end of the motor 9 is connected to a screw. By driving the screw to rotate, the push nut 10 on it can move linearly along the extension direction of the screw. The extension direction of the screw is towards the locking assembly 1. Each end of the push nut 10 is connected to a different transverse locking block 8 through a connecting rod 11. The connecting rods 11 have the same structural specifications and are used to convert the linear thrust provided by the push nut 10 into the force required for the transverse movement of the two transverse locking blocks 8. The design of the connecting rods 11 first ensures the consistency and reliability of the movement of the two transverse locking blocks 8. At the same time, the structure of the entire unlocking device is simplified, and the installation and operation space required is saved.
[0050] Furthermore, the connecting rod 11 has a first connecting end 111, a second connecting end 112, and a rotating support end 113; the rotating support end 113 is rotatably connected to the side wall of the connecting frame 4, providing a fulcrum for the connecting rod 11; the first connecting end 111 and the second connecting end 112 are respectively slots opened on the end face of the connecting rod 11 and located on both sides of the rotating support end 113; the first connecting end 111 is used to slide in connection with the first connecting protrusion on the transverse locking block 8, and the second connecting end 112 is used to slide in connection with the second connecting protrusion of the push nut 10.
[0051] The entire structure of link 11 needs to be combined Figure 5 To illustrate the structure, the connecting rod 11 is generally triangular, with the rotating support end 113 at one vertex. It is connected to the side wall of the connecting frame 4 via a point rotation connection (achieved through a pin structure). The first connecting end 111 and the second connecting end 112 are slots formed on the end face of the connecting rod 11. The length of these slots needs to be set based on the required travel of the two transverse locking blocks 8. For details, please refer to [reference needed]. Figure 3 and Figure 5 In comparison, the positions of the first and second connecting protrusions in the slot are different in the two working states.
[0052] The first and second connecting protrusions slide and engage with their corresponding slots. To allow the interaction between the first connecting protrusion and the slot, driven by the push nut 10, the triangular side containing the slot rotates around the pivot point provided by the rotary support end 113. Specifically, the force exerted by the first connecting protrusion on the corresponding slot causes the entire connecting rod 11 to rotate around the rotary support end 113. Simultaneously, the other triangular side with a corresponding slot swings in coordination. This slot, through its interaction with the second connecting protrusion, drives the two transverse locking blocks 8 to move. The entire action process conforms to mechanical control logic, combined with the attached... Figure 5 It is clear that this will not be elaborated upon here.
[0053] In a preferred embodiment, see Figure 4 A limit switch bracket 12 is also provided in the middle of the push nut 10, and a limit switch 13 corresponding to the limit switch bracket 12 is provided on the side wall of the motor 9. The limit switch 13 is used to limit the movement stroke of the push nut 10.
[0054] To ensure the structural reliability of the unlocking device, the push nut 10 and the side wall of the motor 9 are equipped with mutually cooperating limit switch brackets 12 and limit switches 13. Their main function is to control the downward displacement of the push nut 10. When the two transverse locking blocks 8 move from being far apart to being close to each other, the motor 9 needs to drive the push nut 10 to move in the same direction, moving the push nut 10 away from the locking assembly 1. To limit the travel of the push nut 10, the limit switch brackets 12 and 13 are contacted to indicate that the motor 9 can stop driving. At this time, the two transverse locking blocks 8 have already engaged or have reached the set position.
[0055] In a preferred embodiment, see Figure 7 The control component 3 includes at least: a controller 31 and a wireless remote controller 32 connected by a signal. The wireless remote controller 32 is used to send an unlock command to the controller 31, and the controller 31 is used to control the operation of the motor 9.
[0056] The design of control component 3 can further improve the reliability of the unlocking device. In this embodiment, control component 3 includes controller 31 and wireless remote controller 32, and the two are connected in communication. In terms of control logic: wireless remote controller 32 sends an unlock signal, which is transmitted to controller 31 through signal encoding, transmission, decoding and other links. After receiving the unlock signal, controller 31 starts drive motor 9, and the horizontal locking block 8 opens under the drive. By monitoring the drive motor feedback system (which converts the number of rotations into the amount of rise through a calculation formula), the amount of rise can be detected in real time until the set value is reached. Controller 31 receives the drive motor feedback and stops the action. Then, controller 31 sends an unlocking completion signal to wireless remote controller 32. Regarding abnormal handling: the time from when controller 31 receives the unlock signal to when it receives drive motor feedback is set to 10 seconds. The controller 31 has a built-in timer set to 15 seconds. If controller 31 does not receive drive motor feedback within 15 seconds, controller 31 will attempt to unlock a second time and send a second unlock signal to wireless remote controller 32. If the second unlock also times out, controller 31 will send an unlocking failure signal to wireless remote controller 32.
[0057] Combination Figures 1-7Based on the above description, this application proposes a rocket and launch pad unlocking device, the specific working principle of which is as follows: First, the rocket to be launched is fixed in the set position on the launch pad 02. Then, the control component 3 controls the motor 9 in the drive component 2 to rotate, thereby driving the push nut 10 to move the two symmetrically arranged connecting rods 11, so that the transverse locking blocks 8 move along the slide rail 6 in a direction that brings them closer to each other, thereby surrounding the connection part 01 and locking it (the push nut 10 is protected by the travel of the limit switch 13 and the limit switch bracket 12 during this process). Subsequently, when the control component 3 receives the rocket unlocking command, it controls the drive motor 9 to rotate in the opposite direction, so that the push nut 10 moves from its current position towards the locking component 1. The two transverse locking blocks 8 move along the slide rail 6 in a direction that moves away from each other under the drive of the connecting rods 11, releasing the fixation of the connection part 01 and completing the release of the rocket to be launched.
[0058] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in this application is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept.
