Description

Technical Field

[0001] The invention relates to the technical field of manned space flight, and in particular to a rescue satellite hose compression and release device. Background Art

[0002] According to the rescue satellite rescue mission plan, when the faulty satellite needs to be repaired, the rescue satellite will dock or fly with the faulty satellite, and then the robotic arm will grab the hose on the rescue satellite and connect it to the faulty satellite. When the hose is launched with the rescue satellite, it needs to be pressed and fixed on the rescue satellite to cope with the severe impact and vibration during launch. After entering orbit, the hose is released and separated from the rescue satellite.

[0003] The traditional compression and release device on the satellite is generally a pyrotechnic compression and release device, which compresses the hose by bolts. The pyrotechnic compression and release device contains gunpowder and a connecting cable. The gunpowder is triggered by an electrical signal to detonate, and the cutter is driven to cut off the connected bolts to release the hose. The electrical signal detonation requires the assembly of corresponding cables and excitation circuits. For rescue satellites equipped with robotic arms and shearing tools, these will undoubtedly increase the complexity of the hose compression and release device, increase the probability of failure, reduce the reliability of the hose compression and release device, and ultimately reduce the reliability of the entire satellite system.

[0004] Therefore, how to improve the reliability of the hose compression release device becomes a technical problem that needs to be solved urgently by those skilled in the art. Summary of the invention

[0005] The invention provides a rescue satellite hose compression and release device, which is used to solve the problem of how to improve the reliability of the hose compression and release device.

[0009] The base, cable tie and hose are put into orbit with the rescue satellite; the cable tie can be cut with the help of a cutting tool to separate the hose from the base.

[0010] In some embodiments, there is one accommodating groove, the opening of which is inclined upward and in a semicircular shape, and is disposed on one side of the base.

[0011] In some of these embodiments, a support column is provided on the other side of the base;

[0012] The avoidance groove is formed between the support column and the accommodating groove;

[0013] One end of the cable tie is provided with a cable tie head, and the other end passes through the cable tie head after passing through the bottom of the base, the top of the accommodating groove, the top of the avoidance groove and the top of the supporting column in sequence.

[0014] In some of the embodiments, the top of the support column is provided with an avoidance hole for the cable tie to pass through;

[0015] An avoidance channel is arranged at the bottom of the base.

[0016] In some embodiments, there are two accommodating grooves, the openings of which are inclined upward and semicircular, and are disposed on opposite sides of the base.

[0017] In some of the embodiments, the avoidance groove is formed between the two accommodating grooves;

[0018] One end of the cable tie is provided with a cable tie head, and the other end passes through the cable tie head after passing through the bottom of the base, the top of one of the accommodating grooves, the top of the avoidance groove and the top of another accommodating groove in sequence.

[0019] In some of the embodiments, an avoidance channel is provided at the bottom of the base.

After that, the base, cable tie and hose enter orbit with the rescue satellite. After entering orbit, since an escape groove for avoiding the shearing tool is formed on the base, the cable tie can be cut with the help of the shearing tool so that the hose can be separated from the base. Compared with the traditional compression and release device on the satellite, there is no need to install the detonation cable and the excitation circuit, and the structure is also simpler, which greatly reduces the possibility of failure of the hose compression and release system and improves the reliability of the hose compression and release system. There is no need to assemble and install gunpowder, which avoids the potential risks brought by the installation and storage of gunpowder. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] 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.

[0037] As described in the background technology, the conventional compression and release device on the satellite is generally a pyrotechnic compression and release device, which compresses the hose by bolts. The pyrotechnic compression and release device contains gunpowder and a connecting cable. The gunpowder is detonated by an electrical signal, and the cutter is driven to cut off the connected bolts to release the hose. The electrical signal detonation requires the assembly of corresponding cables and excitation circuits. For rescue satellites equipped with mechanical arms and shearing tools, these will undoubtedly increase the complexity of the hose compression and release system, increase the probability of failure, reduce the reliability of the hose compression and release system, and ultimately reduce the reliability of the entire satellite system.

[0038] To solve the above problems, refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 and Fig.12On the one hand, the present invention provides a rescue satellite hose compression and release device 100, including a base 110 and a cable tie 120. A receiving groove 111 for accommodating a hose 200 and an avoidance groove 112 for avoiding a shearing tool 400 are formed on the base 110. The base 110 is suitable for being detachably connected to a cabin board 300 of a rescue satellite. The cable tie 120 is installed on the base 110, and is suitable for constraining the hose 200 in the receiving groove 111. It should be noted that the hose 200 is installed with rescue cables and the like, and the cross-section is not necessarily a regular circle. The cable tie 120 has a certain flexibility, and can be bent and tightly attached to the outer wall of the hose 200 along the circumference of the hose 200 to press the hose 200 in the receiving groove 111. Before launching the rescue satellite, the base 110 is installed on the cabin 300 of the rescue satellite, and the hose 200 is placed in the receiving groove 111, and then the cable tie 120 is used to press the hose 200 in the receiving groove 111 to cope with the severe impact and vibration during launch. After that, the base 110, the cable tie 120 and the hose 200 enter the orbit with the rescue satellite. After entering the orbit, since the avoidance groove 112 for avoiding the shearing tool 400 is formed on the base 110, the cable tie 120 can be cut with the help of the shearing tool 400 to separate the hose 200 from the base 110. Compared with the traditional compression and release device on the satellite, there is no need to install the detonation cable and the excitation circuit, and the structure is also simpler, which greatly reduces the possibility of failure of the hose compression and release system and improves the reliability of the hose compression and release system. There is no need to assemble and install gunpowder, which avoids the potential risks brought by the installation and storage of gunpowder, and finally improves the reliability of the entire satellite system.

[0039] Preferably, the base 110 is made of non-metallic materials such as polyimide, and the cable tie 120 is made of nylon. Compared with the traditional compression release system using metal materials, the overall weight is lighter, which is conducive to increasing the payload and saving the rescue satellite fuel.

[0040] In some embodiments, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, there is one receiving groove 111, which opens obliquely upward and is arranged at the top of one side of the base 110. The opening is semicircular, which is not only conducive to the loading and unloading of the hose, but also has a certain fault tolerance and adaptability to the actual diameter deviation of the hose. A support column 113 is arranged at the top of the other side of the base 110. The avoidance groove 112 is formed between the support column 113 and the receiving groove 111. A cable tie 120 head is arranged at one end of the cable tie 120, and the other end passes through the bottom of the base 110, the top of the receiving groove 111, the top of the avoidance groove 112 and the top of the support column 113 in turn, and then passes through the cable tie 120 head. Since the cross section of the hose 200 will be deformed when the hose 200 is fixed on the base 110, on the one hand, the opening of the receiving groove 111 is set to be obliquely upward; on the other hand, the receiving groove 111 is a semicircular structure, which is conducive to the cable tie 120 and the receiving groove 111 to form a good match, and the position of the hose 200 can be better constrained before the hose 200 enters orbit with the rescue satellite. An avoidance hole 1131 is provided at the top of the support column 113 for the cable tie 120 to pass through. An avoidance channel 114 is provided at the bottom of the base 110. The avoidance hole 1131 and the avoidance channel 114 can effectively prevent the cable tie 120 from moving relative to the base 110 and prevent the cable tie 120 from detaching from the base 110, thereby ensuring the fixing effect of the hose 200.

[0041] In other embodiments, such as Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 and Fig.12 As shown, there are two receiving grooves 111, and the openings are inclined upward and arranged at the tops of the opposite sides of the base 110. The openings are semicircular, which is not only conducive to the loading and unloading of the hose, but also has a certain tolerance and adaptability to the actual diameter deviation of the hose. The avoidance groove 112 is formed between the two receiving grooves 111. A head of the tie 120 is provided at one end of the tie 120, and the other end passes through the bottom of the base 110, the top of one of the receiving grooves 111, the top of the avoidance groove 112 and the top of the other receiving groove 111 in turn, and then passes through the head of the tie 120. Since the cross sections of the two hoses 200 will be deformed when the two hoses 200 are fixed to the base 110, on the one hand, the openings of the two receiving grooves 111 are respectively set to be obliquely upward; on the other hand, the two receiving grooves 111 are both semicircular structures, which is conducive to the cable tie 120 and the two receiving grooves 111 to form a better match, and the positions of the two hoses 200 can be better constrained before the two hoses 200 enter orbit with the rescue satellite. An escape channel 114 is set at the bottom of the base 110. The escape channel 114 can effectively prevent the cable tie 120 from moving relative to the base 110 and prevent the cable tie 120 from detaching from the base 110, thereby ensuring the fixing effect of the hose 200.

[0042] Specifically, in the exemplary embodiment, a mounting hole is provided on opposite sides of the bottom of the base 110. Accordingly, two mounting holes are provided on the cabin board 300 of the rescue satellite. The base 110 can be fixed to the cabin board 300 of the rescue satellite through the two mounting holes using two connectors 130.

[0043] Preferably, the mounting hole is a threaded hole, and correspondingly, the connecting member 130 is a bolt. The mounting hole can also be a socket, and correspondingly, the connecting member 130 is a pin.

[0044] Preferably, a plurality of weight-reducing holes 115 are provided on the base 110 to reduce the weight of the base 110, which is beneficial to increasing the effective load and saving the fuel of the rescue satellite.

[0045] On the other hand, a rescue satellite hose compression and release system includes a rescue satellite, a hose 200, a shearing tool 400, and a rescue satellite hose compression and release device 100 provided by any of the above embodiments. The base 110 is detachably connected to the cabin 300 of the rescue satellite through a connector 130. The hose 200 is disposed in a receiving groove 111 of the base 110. The shearing tool 400 is used to shear the cable tie 120. Before launching the rescue satellite, the base 110 is installed on the cabin 300 of the rescue satellite, and the hose 200 is placed in the receiving groove 111, and then the cable tie 120 is used to compress the hose 200 in the receiving groove 111 to cope with severe impact and vibration during launch. Afterwards, the base 110, the cable tie 120, and the hose 200 enter orbit with the rescue satellite. After entering orbit, since the base 110 is provided with an escape groove 112 for the shearing tool 400 to escape, the shearing tool 400 can be used to cut the cable tie 120 so that the hose 200 can be separated from the base 110. Compared with the traditional compression and release device on the satellite, there is no need to install the detonation cable and the excitation circuit, and the structure is also simpler, which greatly reduces the possibility of failure of the hose compression and release system and improves the reliability of the hose compression and release system. There is no need to assemble and install gunpowder, which avoids the potential risks brought by the installation and storage of gunpowder, and ultimately improves the reliability of the entire satellite system.
