Description

Technical Field

[0001] The present invention relates to the technical field of on-orbit cabinets of space stations, and particularly relates to a heterogeneous hard pipe for an on-orbit cabinet and an on-orbit cabinet. Background Art

[0002] With the development of manned spaceflight technology, establishing a long-term inhabited and working environment in outer space has become the focus of the human spaceflight cause. The logistics supply of the International Space Station is extremely expensive and difficult compared to any previous natural exploration activities of humans. The logistics problems faced in establishing bases on the moon and Mars in the future are even more severe. Especially in response to emergencies, the losses caused by delays in ground support will be immeasurable. Therefore, considering the initiative of astronauts, enhancing the autonomous maintenance and support capabilities of facilities by providing a series of tools and technical support to personnel is an important measure to solve the logistics supply problem.

[0003] The on-orbit maintenance and adjustment operation cabinet (hereinafter referred to as the "on-orbit cabinet") is a scientific and technical experimental platform planned for a space station application system, mainly providing a workplace for on-orbit fault diagnosis, relay-level maintenance, and manual or mechanical operations for the payload of the space station. The on-orbit cabinet can utilize the in-cabin space environmental conditions provided by the manned space station, as well as the on-orbit operation, maintenance, and replacement capabilities of astronauts, and carry out on-orbit maintenance, adjustment operations, and experimental research based on external mechanical, electrical, thermal, information, measurement and control, and other resource constraints.

[0004] The on-orbit maintenance operation support unit (hereinafter referred to as the "operation box") is the main functional component of the on-orbit cabinet system, providing a large-volume, multi-type interface, and environmentally controllable enclosed working space to ensure that astronauts can directly participate in some manual on-orbit operations and scientific experiments. To ensure the smooth and safe progress of operations and experiments, it is necessary to study and design the operation box into a system that is observable, measurable, replaceable, and controllable during the operation and experimental processes. Observable means that astronauts can directly observe the object being operated and the operation process through the transparent panel of the on-orbit maintenance operation support unit; measurable means that the object being operated is preliminarily measured using configured auxiliary equipment (such as a three-dimensional scanner, intelligent induction maintenance unit, etc.); replaceable means that the devices in the on-orbit maintenance operation support unit can be replaced and freely combined and disassembled according to the needs of operations and experiments; controllable means that the environment (such as light, temperature, gas, etc.) and fine operations (such as the end-precision operation of a dexterous manipulator, etc.) in the on-orbit maintenance operation support unit are controllable. The environmental monitoring and the treatment of waste gas and waste particulate matter in the on-orbit maintenance operation support unit are mainly completed by the three-waste treatment unit.

[0005] The ambient temperature inside the cabin is approximately 19.5°C to 26.5°C. Under the conditions of the semi-closed cabinet configuration of the online cabinet and the strict constraints on the heat leakage of the entire online cabinet by the space station platform, most of the heat generated by the electronic devices when they are powered on and operating in the online cabinet needs to be promptly removed through the thermal control loop. The total inlet and total outlet of the thermal control loop of the online cabinet are on the lower resource panel of the online cabinet. The load of the online cabinet, especially the operation box, adopts a profiling design, and the gap with the main structural frame is very small. At the same time, the operation box is a closed operation space, and many of the internal loads have heat dissipation requirements. Therefore, when introducing the thermal control loop into the operation box, the installability and the sealing performance of passing through the operation box need to be considered.

[0006] At the same time, to ensure the treatment of the three wastes inside the operation box, nitrogen, air, and waste gas discharge interfaces are introduced into the operation box. Among them, the total nitrogen inlet and the total waste gas outlet of the online cabinet are both on the lower resource panel, while the total air inlet is set on the upper resource panel. All of them need to be laid out through rigid pipes in the narrow space at the back and finally introduced into the operation box. The entire process needs to consider the installability and the sealing performance of passing through the operation box. The water inlet and outlet, nitrogen, air, and waste gas discharge interfaces are introduced into the operation box from the outside of the operation box through rigid pipes, but the layout of the narrow space at the back, the installability, and the sealing performance of passing through the operation box need to be considered. The above problems need to be solved urgently. Summary of the Invention

[0007] The present invention provides a heterogeneous rigid pipe for an online cabinet and an online cabinet to solve the problem of the narrow assembly space of the existing online cabinet.

[0008] The technical solution of the present invention to solve the above technical problems is as follows: A heterogeneous rigid pipe for an online cabinet includes a rigid pipe and an L-shaped rigid pipe joint. One end of the rigid pipe is hermetically connected to the L-shaped rigid pipe joint. One end of the L-shaped rigid pipe joint is used for hermetically connecting to the rigid pipe, and the other end of the L-shaped rigid pipe joint is vertically connected to the outer side wall of the back panel of the operation box body inside the online cabinet body; the other end of the rigid pipe is also hermetically connected to a straight rigid pipe joint for connecting to the resource panel of the online cabinet body.

[0009] The beneficial effects of the present invention are: The present invention uses a rigid pipe and an L-shaped rigid joint for connection, and the rigid pipe can be extended and arranged in the narrow space between the back of the online cabinet body and the back panel of the operation box body, and the heterogeneous design of the pipe in the narrow space can be realized. Moreover, the assembly of the rigid pipe at the back of the online cabinet generally requires direct insertion to ensure the reliability of the connection. Therefore, the use of the L-shaped rigid pipe joint can ensure the reliability of the plug-in connection and the sealing performance of passing through the operation box.

[0010] On the basis of the above technical solution, the present invention can also be improved as follows.

[0011] Further, connection lugs are provided at the other end of the L-shaped rigid pipe joint and the free end of the straight rigid pipe joint. The connection lugs are arranged on the circumferential side wall of the other end of the L-shaped rigid pipe joint or the free end of the straight rigid pipe joint. The L-shaped rigid pipe joint is bolted to the outer side wall of the back plate of the operation box body inside the online cabinet through the connection lug at its other end, and the straight rigid pipe joint is connected to the resource panel on the online cabinet body through the connection lug at its free end.

[0012] The beneficial effect of adopting the above further solution is that the arrangement of the connection lugs can ensure the tight connection between the L-shaped rigid pipe joint and the outer side wall of the back plate, and the tight connection between the straight rigid pipe joint and the resource panel, ensuring the sealing performance.

[0013] Further, the L-shaped rigid pipe joint includes a rigid pipe connection section and a sealing connection section vertically connected into an L-shaped structure. The free end of the rigid pipe connection section is used for sealing connection with a rigid pipe, and the free end of the sealing connection section is vertically connected to the back plate of the operation box body inside the online cabinet; the inner diameter of a section of the sealing connection section near the free end is larger than that of a section away from the free end, so that an annular step is formed inside the sealing connection section.

[0014] The beneficial effect of adopting the above further solution is that the arrangement of the annular step can facilitate the insertion of the control pipeline in the operation box into the sealing connection section and abut against the annular step.

[0015] An online cabinet includes the heterogeneous rigid pipe for the online cabinet as described above, and further includes an operation box body and an online cabinet body.

[0018] A control pipeline is provided inside the assembly sandwich layer. One end of the control pipeline passes through the outer backboard and is hermetically plugged into the L-shaped hard pipe joint at one end of the rigid pipe, and the other end of the control pipeline is connected to a quick-break joint on the inner backboard.

The first sealing plate abuts against one side wall of the outer backboard inside the assembly sandwich layer, and the second sealing plate abuts against one side wall of the inner backboard inside the assembly sandwich layer.

[0020] The beneficial effect of adopting the above further scheme is that the setting of the first and second sealing plates enables the control pipeline to be hermetically arranged inside the assembly sandwich layer, realizing the hermetic plugging between the heterogeneous hard pipe and the quick-break joint.

[0021] Furthermore, at least one circle of first sealing rings is provided on the first sealing plate, and at least one circle of second sealing rings is provided on the second sealing plate. The first sealing plate is hermetically abutted against one side wall of the outer backboard inside the assembly sandwich layer through at least one circle of first sealing rings, and the second sealing plate is hermetically abutted against one side wall of the inner backboard inside the assembly sandwich layer through at least one circle of second sealing rings.

Detailed implementation manners

[0039] The principles and features of the present invention will be described below with reference to the accompanying drawings. The examples given are only used to explain the present invention and are not intended to limit the scope of the present invention.

[0040] As Figures 1 to 3 shown, a heterogeneous rigid pipe 200 for an online cabinet in this embodiment includes a rigid pipe and an L-shaped rigid pipe connector 201. One end of the rigid pipe is hermetically inserted with an L-shaped rigid pipe connector 201. One end of the L-shaped rigid pipe connector 201 is used for hermetically connecting with the rigid pipe, and the other end of the L-shaped rigid pipe connector 201 is vertically connected to the outer side wall of the back panel of the operation box body 206 inside the online cabinet body 207. The other end of the rigid pipe is also hermetically connected with a straight-line rigid pipe connector 223 for connecting the resource panel of the online cabinet body 207.

[0041] As Figure 4 and Figure 5 shown, connecting ear plates 202 are provided at the other end of the L-shaped rigid pipe connector 201 and the free end of the straight-line rigid pipe connector 223 in this embodiment. The connecting ear plates 202 are arranged on the peripheral side wall of the other end of the L-shaped rigid pipe connector 201 or the free end of the straight-line rigid pipe connector 223. The L-shaped rigid pipe connector 201 is bolted to the outer side wall of the back panel of the operation box body 206 inside the online cabinet body 207 through the connecting ear plate 202 at its other end, and the straight-line rigid pipe connector 223 is connected to the resource panel on the online cabinet body 207 through the connecting ear plate 202 at its free end. The setting of the connecting ear plates can ensure the tight connection between the L-shaped rigid pipe connector and the outer side wall of the back panel and ensure the sealing performance.

[0042] As Figure 2As shown in the figure, the L-shaped rigid pipe joint 201 of this embodiment includes a rigid pipe connection section 203 and a sealed connection section 204 that are vertically connected to form an L-shaped structure. The free end of the rigid pipe connection section 203 is used for sealed connection with a rigid pipe, and the free end of the sealed connection section 204 is vertically connected to the back plate of the operation box body 206 inside the on-line cabinet body 207. The inner diameter of a section of the sealed connection section 204 near the free end is larger than that of a section away from the free end, so that an annular step 205 is formed inside the sealed connection section 204. The setting of the annular step can facilitate the insertion of the control pipeline in the operation box into the sealed connection section and abut against the annular step.

[0043] Specifically, the L-shaped rigid pipe joint 201 adopts a machining structure. The rigid pipe connection section 203 can be directly welded and fixed to the rigid pipe. By machining the L-shaped rigid pipe joint 201, it can ensure the lowest height during the vertical turning process of gas (liquid), and then welding with the rigid pipe to ensure the layout of the rigid pipe in a small space.

[0044] This embodiment uses a rigid pipe and an L-shaped rigid joint for connection, which can extend and arrange the rigid pipe in the narrow space between the back of the on-line cabinet body and the back plate of the operation box body, and can realize the heterogeneous design of the pipeline in the narrow space. Moreover, the assembly of the rigid pipe on the back of the on-line cabinet generally requires direct insertion to ensure the reliability of the connection. Therefore, using an L-shaped rigid pipe joint can ensure the reliability of the plug-in connection and the sealing performance of passing through the operation box.

[0045] As Figure 6 shown in the figure, an on-line cabinet of this embodiment includes the heterogeneous rigid pipe for the on-line cabinet as described above, and also includes an operation box body 206 and an on-line cabinet body 207. The operation box body 206 is installed inside the on-line cabinet body 207. An assembly interval is reserved between the back plate of the operation box body 206 and the back of the on-line cabinet body 207. The L-shaped rigid pipe joint 201 at one end of the rigid pipe is connected to the outer side wall of the back plate of the operation box body 206. The rigid pipe extends and is arranged along the assembly interval and is fixed on the frame on the back of the on-line cabinet body 207. The straight rigid pipe joint 223 at the other end of the rigid pipe is connected to the resource panel of the on-line cabinet body 207.

[0046] As Figure 4As shown, the back panel of the operation box body 206 in this embodiment includes an inner back panel 208 and an outer back panel 209. The inner back panel 208 and the outer back panel 209 are arranged at intervals to form an assembly sandwich layer. The outer back panel 209 is arranged at intervals from the back of the on-line cabinet body 207. The L-shaped hard pipe joint 201 at one end of the rigid pipe is connected to the outer side wall of the outer back panel 209. A control pipeline 225 is arranged in the assembly sandwich layer. One end of the control pipeline 225 passes through the outer back panel 209 and is hermetically inserted into the L-shaped hard pipe joint 201 at one end of the rigid pipe. The other end of the control pipeline 225 is connected to the quick-break joint 220 on the inner back panel. Specifically, a plunger joint 226 is arranged at one end of the control pipeline 225. The plunger joint 226 passes through the outer back panel 209 and is hermetically inserted into the L-shaped hard pipe joint 201 at one end of the rigid pipe. In this embodiment, the cooperation between the rigid pipe and the L-shaped rigid joint can achieve the through-cabin sealing of the operation box. The control pipeline is first hermetically installed with the operation box. At the same time, the plunger joint 226 is extended to be connected with the external hard pipe to ensure the operability and sealing performance.

[0047] As Figure 4 and Figure 5 shown, on the outer side walls of the control pipeline 225 near both ends in this embodiment, a first sealing plate 210 and a second sealing plate 211 are respectively arranged. The first sealing plate 210 abuts against one side wall of the outer back panel 209 located in the assembly sandwich layer, and the second sealing plate 211 abuts against one side wall of the inner back panel 208 located in the assembly sandwich layer. The setting of the first sealing plate and the second sealing plate enables the control pipeline to be hermetically arranged in the assembly sandwich layer, realizing the hermetic insertion between the heterogeneous hard pipe and the quick-break joint.

[0048] As Figure 5 shown, at least one circle of first sealing rings 212 is arranged on the first sealing plate 210 in this embodiment, and at least one circle of second sealing rings is arranged on the second sealing plate 211. The first sealing plate 210 is hermetically abutted against one side wall of the outer back panel 209 located in the assembly sandwich layer through at least one circle of first sealing rings 212, and the second sealing plate 211 is hermetically abutted against one side wall of the inner back panel 208 located in the assembly sandwich layer through at least one circle of second sealing rings.

[0049] As Figure 4 and Figure 5 shown, an assembly bracket 214 is arranged on one side wall of the outer back panel 209 located in the assembly sandwich layer or / and on one side wall of the inner back panel 208 located in the assembly sandwich layer in this embodiment. An electromagnetic valve 224 is arranged in the middle of the control pipeline 225 and is supported on the assembly bracket 214. The setting of the assembly bracket can provide effective structural support for the electromagnetic valve.

[0050] AsFigure 1 and Figure 3 As shown in Figure 3 , the heterogeneous rigid pipes 200 for the online cabinet in this embodiment include an exhaust gas pipeline 215, a nitrogen gas pipeline 216, and an air pipeline 217. The control pipeline 225 includes an exhaust gas control pipeline, a nitrogen gas control pipeline, and an air control pipeline. One end of the exhaust gas control pipeline passes through the outer back panel 209 and is hermetically inserted into the L-shaped rigid pipe joint 201 at one end of the exhaust gas pipeline 215, and the other end of the exhaust gas control pipeline is connected to the first quick-break joint on the inner back panel 208. One end of the nitrogen gas control pipeline passes through the outer back panel 209 and is hermetically inserted into the L-shaped rigid pipe joint 201 at one end of the nitrogen gas pipeline 216, and the other end of the nitrogen gas control pipeline is connected to the second quick-break joint on the inner back panel 208. One end of the air control pipeline passes through the outer back panel 209 and is hermetically inserted into the L-shaped rigid pipe joint 201 at one end of the air pipeline 217, and the other end of the air control pipeline is connected to the third quick-break joint on the inner back panel 208.

[0051] Specifically, as Figure 1 and Figure 2 shown in Figure 2 , the other end of the air pipeline 217 in this embodiment is connected to the upper resource panel 221, and the other ends of the nitrogen gas pipeline 216 and the exhaust gas pipeline 215 are both connected to the lower resource panel 222. The other ends of the water inlet pipeline 218 and the water outlet pipeline 219 are both connected to the lower resource panel 222.

[0052] More specifically, as Figure 1 and Figure 3 shown in Figure 3 , the heterogeneous rigid pipes for the online cabinet in this embodiment include a water inlet pipeline 218 and a water outlet pipeline 219. The control pipeline 225 includes a water inlet control pipeline and a water outlet control pipeline. One end of the water inlet control pipeline passes through the outer back panel 209 and is hermetically inserted into the L-shaped rigid pipe joint 201 at one end of the water inlet pipeline 218, and the other end of the water inlet control pipeline is connected to the fourth quick-break joint on the inner back panel 208. One end of the water outlet control pipeline passes through the outer back panel 209 and is hermetically inserted into the L-shaped rigid pipe joint 201 at one end of the water outlet pipeline 219, and the other end of the water outlet control pipeline is connected to the fifth quick-break joint on the inner back panel 208.

[0053] For the online cabinet in this embodiment, the assembly interval between the back skin of the online cabinet body and the back panel of the internal operation box is very limited, and there are also arrangements of frame structures and cable nets on the back. The online cabinet in this embodiment can extend and arrange the heterogeneous rigid pipes for the online cabinet along the assembly interval and fix them on the structural frame of the online cabinet body, so as to arrange the heterogeneous rigid pipes in the narrow space between the operation box body and the back of the online cabinet body.
