DETAILED DESCRIPTION
[0040] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0041] As described in the background technology, currently, before launch, there is no interface reserved for installing a debris protection device in the upward position of the robotic arm, and the surface of this area has been covered with multiple layers, with no handrails or other fixed interfaces around it. Therefore, how to install a debris protection device in orbit in the upward area of the robotic arm has become a technical problem that needs to be urgently solved by technical personnel in this field.
[0042] It should be noted that during launch, the pyrotechnic hold-down seat is connected to the robotic arm to limit the movement of the robotic arm. After entering orbit, the pyrotechnic hold-down seat explodes and disconnects from the robotic arm, allowing the robotic arm to move and perform tasks. The pyrotechnic hold-down seat after the explosion is left outside the cabin as waste.
[0043] To solve the above problems, refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The present invention provides a space station debris protection device based on a pyrotechnic compression seat, comprising a protection component 110, a first connection component 120, and a second connection component 130. The protection component 110 is used to cover the space station cabin, prevent space debris from directly hitting the cabin, and withstand the impact of space station debris. The first connection component 120 is installed on the protection component 110, and is suitable for connecting or disconnecting with a universal handle. The second connection component 130 is installed on the protection component 110, and is suitable for connecting or disconnecting with the pyrotechnic compression seat 200.
[0044] When installing the debris protection device on-orbit to the upward region of the robotic arm, first, the universal handle is connected to the first connecting assembly 120, and the astronaut uses the universal handle to drive the protection assembly 110 and the second connecting assembly 130 to move to the upward region of the robotic arm to prevent the protection assembly 110 and the second connecting assembly 130 from drifting at will. Then, the abandoned pyrotechnic pressing seat 200 is used as the installation point of the protection assembly 110, and the second connecting assembly 130 is connected to the pyrotechnic pressing seat 200 to complete the task of installing the debris protection device, further improving the overall debris protection capability of the space station and extending its on-orbit life.
[0045] Specifically, in the example, Figure 1 , Figure 2 and Figure 3As shown, the second connecting assembly 130 includes a locking disk 131, three locking beads 132, a transmission shaft 133, a housing 134, a damper 135 and an operating wheel 136. A plug connector 1311 is formed on the bottom surface of the locking disk 131. The plug connector 1311 is suitable for being inserted into or detached from the socket on the pyrotechnic compression seat 200. A receiving cavity is formed inside the plug connector 1311, and three first clearance holes respectively connected to the receiving cavity are formed circumferentially on the side wall of the plug connector 1311. The three locking beads 132 are all installed in the receiving cavity. The bottom end of the transmission shaft 133 is inserted into the receiving cavity, and can move downward so that one side of the three locking beads 132 respectively passes through the corresponding first clearance holes and protrudes out of the receiving cavity, or moves upward so that the three locking beads 132 retract into the receiving cavity. It should be noted that the outer diameter of the first clearance hole is smaller than the inner diameter to prevent the locking bead 132 from completely escaping from the accommodating chamber. The inner wall of the accommodating chamber is provided with a thread, and the outer wall of the transmission shaft 133 is also provided with a thread, and the outer wall of the transmission shaft 133 is connected to the inner wall of the accommodating chamber by a screw connection. A circle of grooves is provided at the bottom end of the transmission shaft 133 for temporarily accommodating the locking bead 132. When the transmission shaft 133 rotates, the bottom end of the transmission shaft 133 moves downward or upward to force one side of the three locking beads 132 to pass through the corresponding first clearance hole to protrude out of the accommodating chamber or retract into the accommodating chamber. The housing 134 is provided on the outside of the transmission shaft 133 to protect the internal components and prevent the external interference with the movement of the internal components. The damper 135 is installed in the housing 134 to limit the spontaneous rotation of the transmission shaft 133 and to limit the spontaneous axial movement of the transmission shaft 133 to prevent misoperation. The operating wheel 136 is installed at the top of the transmission shaft 133 to facilitate the astronaut to operate the transmission shaft 133 by hand.
[0046] The connection process and principle of the second connection assembly 130 and the pyrotechnic pressing seat 200 are as follows: First, insert the plug connector 1311 of the locking disk 131 into the socket at the top of the pyrotechnic pressing seat 200, and the bottom end of the locking disk 131 presses against the top of the pyrotechnic pressing seat 200 to preliminarily connect the second connection assembly 130 and the pyrotechnic pressing seat 200. Next, rotate the operating wheel 136 to drive the transmission shaft 133 to rotate, and the bottom end of the transmission shaft 133 moves downward. During this process, the groove on the outer wall of the transmission shaft 133 forces one side of the locking bead 132 to pass through the first clearance hole and protrude out of the accommodating cavity, and the locking bead 132 presses against the inner wall of the socket of the pyrotechnic pressing seat 200, further improving the stability of the connection between the second connection assembly 130 and the pyrotechnic pressing seat 200.
[0047] Preferably, the locking disk 131 is a disc structure, which effectively increases the contact area between the locking disk 131 and the pyrotechnic pressing seat 200, thereby improving the connection stability.
[0048] Preferably, a plurality of weight-reducing holes are provided on the locking disk 131 to reduce the weight of the locking disk 131 and provide a certain shock-absorbing function. In addition, it is convenient for astronauts to observe through the weight-reducing holes whether the plug connector 1311 of the locking disk 131 is aligned with the plug hole of the pyrotechnic pressing seat 200, thereby improving the installation efficiency of the protective assembly 110.
[0049] Preferably, a plurality of first clearance holes are formed along the circumferential direction on the side wall of the plug connector 1311. One side of the locking bead 132 can pass through any of the clearance holes, thus effectively improving the locking efficiency.
[0050] Preferably, the top end of the transmission shaft 133 is connected to the middle of the operating wheel 136 by screws to facilitate the disassembly and assembly of the operating wheel 136 .
[0051] Preferably, a plurality of limiting grooves are provided on the side wall of the operating wheel 136 along the circumferential direction to increase the friction between human fingers and the operating wheel 136 and improve the operating effect.
[0052] Preferably, a vertical guide groove is formed on the inner walls on opposite sides of the shell 134. The damper 135 includes a lower limit plate 1352, an upper limit plate 1351 and a tightening spring 1353. A guide block adapted to the vertical guide groove is provided on opposite sides of the lower limit plate 1352. The guide blocks on both sides can slide up and down along the vertical guide grooves on the corresponding sides. It should be pointed out that the lower limit plate 1352 can only move up and down, but cannot rotate around its own axis. A circle of limit teeth is provided on the top surface of the lower limit plate 1352. The upper limit plate 1351 is sleeved on the upper part of the transmission shaft 133, and a circle of limit teeth is also provided on the bottom surface. When the upper limit plate 1351 rotates with the transmission shaft 133, since the lower limit plate 1352 cannot rotate, the limit teeth of the lower limit plate 1352 and the limit teeth of the upper limit plate 1351 are used to provide a damping force for the rotation of the transmission shaft 133 to prevent the transmission shaft 133 from rotating spontaneously. The tightening spring 1353 is sleeved on the upper part of the transmission shaft 133, and the bottom end is fixedly connected to the top of the locking plate 131, and the top end abuts against the bottom surface of the lower limit plate 1352, so that the top surface of the lower limit plate 1352 is closely fitted with the top surface of the upper limit plate 1351, and the top surface of the upper limit plate 1351 abuts against the top of the housing 134, thereby limiting the transmission shaft 133 from spontaneously moving in the axial direction. When the upper limit plate 1351 moves downward with the transmission shaft 133, the axial length of the tightening spring 1353 is gradually shortened, and the tightening force is gradually increased.
[0053] Specifically, in the example, Figure 1As shown, the space station debris protection device based on the pyrotechnic compression seat also includes an adapter 140. One end of the adapter 140 is respectively installed on the top surface of the protection component 110, and the other end is respectively installed on the locking disk 131 of the second connecting component 130, so that the second connecting component 130 is connected to the protection component 110.
[0054] Preferably, there are four adapters 140 , one end of which is respectively mounted on the top surface of the protective assembly 110 , and the other end of which is respectively mounted on four sides of the locking disk 131 , so as to improve the stability of the connection between the second connecting assembly 130 and the protective assembly 110 .
[0055] Preferably, each adapter 140 is in a “Z”-shaped structure and has a certain shock-absorbing and buffering effect.
[0056] Preferably, each adapter 140 is provided with a weight-reducing hole to reduce the weight of the adapter 140 .
[0057] Preferably, one end of each adapter 140 is detachably connected to the top surface of the protective component 110 via a screw, and the other end is detachably connected to the locking disk 131 via a screw, so that the disassembly and assembly of the second connecting component 130 is facilitated.
[0058] Specifically, in the example, Figure 1 As shown, a second clearance hole 111 is provided on the protection component 110. The second clearance hole 111 is directly opposite to the second connection component 130, and can be used for the pyrotechnic product compression seat 200 to pass through.
[0059] Preferably, at least one third clearance hole 112 is provided on the protection component 110, and the third clearance hole 112 is used for other structures outside the cabin to pass through. In this way, the movement of the protection component 110 can be restricted by at least two points, which improves the stability of the position of the protection component 110 and ensures the protection effect.
[0060] Preferably, the second clearance hole 111 is opened at one end of the protection component 110. The first connection component 120 is detachably mounted on the middle of the top surface of the protection component 110, and the second connection component 130 is detachably mounted on one end of the top surface of the protection component 110 through the adapter 140.
[0061] Preferably, the first connection assembly 120 includes a connection seat and a limiting protrusion. There are multiple limiting protrusions, which are installed on the side wall of the connection seat along the circumference of the connection seat.
[0062] Specifically, in the example, Figure 1 and Figure 4As shown, the protective component 110 includes a first buffer layer 113, a second buffer layer 114 and a third connecting component 115. The second buffer layer 114 is arranged above the top surface of the first buffer layer 113, and a buffer cavity is reserved between the bottom surface and the top surface of the first buffer layer 113. When hit by debris from the space station, the first buffer layer 113, the second buffer layer 114 and the buffer cavity cooperate to play a good buffering role. The third connecting component 115 is used to connect the second buffer layer 114 and the first buffer layer 113.
[0063] Preferably, the first buffer layer 113 includes four inner flame-retardant cloths and an outer flame-retardant cloth. Each inner flame-retardant cloth is coated with ten layers of aramid cloth stacked in sequence to form a buffer body. Four buffer bodies are stacked in sequence. The outer flame-retardant cloth is coated outside the four buffer bodies. The aramid cloth has a good buffering effect. The flame-retardant cloth is used for flame retardancy. The flame-retardant cloth and the aramid cloth are sewn together using flame-retardant thread to maintain the stability of the structure of the first buffer layer 113.
[0064] Preferably, the second buffer layer 114 is an aluminum plate, which has a good buffering effect. When the space station is hit by debris, the second buffer layer 114 plays a primary buffering role, and the second buffer layer 114 plays a secondary buffering role.
[0065] Preferably, the second buffer layer 114 and the first buffer layer 113 are connected by a plurality of third connection components 115 to improve the stability of the connection between the second buffer layer 114 and the first buffer layer 113. Each third connection component 115 includes a screw 1151, a sleeve 1152, a washer 1153 and a nut 1154. The sleeve 1152 is sleeved outside the screw 1151, with the top end abutting against the bottom surface of the second buffer layer 114, and the bottom surface abutting against the top surface of the washer 1153. The washer 1153 is sleeved outside the screw 1151, with the bottom surface abutting against the top surface of the first buffer layer 113. The sleeve 1152 and the washer 1153 are used to adjust the distance between the bottom surface of the second buffer layer 114 and the top surface of the first buffer layer 113, thereby adjusting the debris protection effect.
[0066] Preferably, the space station debris protection device based on the pyrotechnics compression seat also includes a heat insulation component, which is coated on the first buffer layer 113, the second buffer layer 114 and the third connection component 115 to play a heat insulation role, thereby facilitating the control of the on-orbit temperature of the protection component 110 and maintaining the temperature stability of the protection component 110. At the same time, it plays a sealing role for the protection component 110. The heat insulation layer can be connected to the first buffer layer 113 by Velcro.
[0067] It should be noted that the overall shape of the protective assembly 110 is designed according to the surface of the space station cabin at the installation location, and holes are opened at corresponding locations to avoid protruding equipment and brackets on the cabin surface. The shape of the adapter 140 can be set according to the on-orbit installation direction and angle, and the distance between the bottom surface of the first buffer layer 113 and the surface of the cabin is controlled to be about 100 mm.
[0068] On the whole, during installation, you only need to insert the plug connector 1311 into the socket on the pyrotechnic clamping seat 200 on track, and then rotate the operating wheel 136, which makes the installation very convenient. The second connecting assembly 130 has an anti-loosening function. Without being subjected to continuous torsional external force, the transmission shaft 133 will not loosen, and there is no risk of it coming off on track. Since the size of the socket of the pyrotechnic clamping seat 200 is unknown in the on-track state, the method of rotational expansion is used, which is suitable for sockets of various sizes and has high adaptability. Using the discarded pyrotechnic clamping seat 200 as the installation interface solves the problem of no reserved interface on the cabin, saving other interface resources of the space station. The overall structure is simple and convenient for processing and assembly.
