Description

Technical Field

[0001] This utility model relates to the technical field of rooftop tents, specifically a detachable ellipsoidal safety cabin. Background Technology

[0002] During emergency rescue operations in natural disasters (such as earthquakes, floods, and forest fires), geological exploration, oil extraction, and other fieldwork, as well as during military exercises, helicopters need to be temporarily parked outdoors to facilitate the rapid transport of the wounded, the delivery of relief supplies, geological exploration, and the swift arrival at designated locations.

[0003] At this point, a temporary helicopter hangar needs to be built. Currently, helicopter hangars are generally fixed, mostly made of reinforced concrete or metal structures. These fixed hangars are sturdy and durable, but have long construction periods, high construction costs, lack of flexible deployment, low site utilization efficiency, and long repair times if damaged. Inflatable hangars are also used to meet the temporary parking needs of small aircraft. Commonly used inflatable hangars are secured by inflating the hangar skin and installing counterweights on both sides. However, these inflatable hangars are relatively small and cannot meet the parking needs of large helicopters, nor can they achieve rapid deployment and folding, and they have poor structural stability, poor wind resistance, and high maintenance costs. Utility Model Content

[0004] The purpose of this invention is to provide a detachable ellipsoidal support cabin to solve the problems of poor stability and inability to quickly deploy and fold existing temporary hangars, thereby improving the overall stability of temporary hangars and the convenience of transporting temporary hangars.

[0005] To achieve the above objectives, the utility model employs the following technical solution:

[0006] A detachable ellipsoidal support cabin includes two bases connected to the ground, a tent fabric, and several arch frames. A rotating shaft is rotatably connected to each base. A fixed arm and a swing arm are mounted on the rotating shaft. Several arch feet are rotatably connected to the fixed arm and the swing arm, respectively. The two ends of the middle arch frame are rotatably connected to the rotating shaft, and the two ends of the remaining arch frames are connected to the arch feet. A pull rope is provided between adjacent arch frames. A drive arm is rotatably connected to the base. The last arch frame connected to the drive arm and the swing arm is rotatably connected. The drive arm drives this arch frame to rotate around the rotating shaft, and also drives the swing arm and the remaining arch frames to rotate around the rotating shaft.

[0007] Furthermore, several of the arches form a truncated ellipsoidal structure, and the tent cover is disposed on the truncated ellipsoidal structure.

[0008] Furthermore, the arch frame includes several arc-shaped rods, and connecting members are provided between the several arc-shaped rods.

[0009] Furthermore, each end of the arc-shaped rod is provided with an insert, and each end of the connector is provided with a groove that engages with the insert. The connector is provided with a plurality of bolts that contact the insert.

[0010] Furthermore, the insert has several protrusions, and the slot has several grooves that are slidably connected to the protrusions.

[0011] Furthermore, the base includes a base plate and a tripod mounted on the base plate, with the pivot rotatably mounted on the tripod.

[0012] Furthermore, the base plate is provided with several long spiral piles.

[0013] Furthermore, the tent fabric is made of Oxford cloth.

[0014] Furthermore, the base is equipped with a speed reducer and a motor. The output end of the speed reducer is connected to the swing arm, and the output end of the motor is connected to the input end of the speed reducer.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. In the initial state, the fixed arm and the swing arm are located on one side of the base, with the fixed arm above the base. Several arch frames are placed parallel to one side of the base. At the same time, the two ends of the middle arch frame are rotatably connected to the rotating shaft, and the two ends of the remaining arch frames are connected to the arch feet provided on the fixed arm and the swing arm. Then, the last arch frame connected to the swing arm is rotatably connected to one end of the drive arm. At this time, since several arch frames are stacked together in parallel, it is convenient to transport the support cabin to various places, improving the convenience of transporting temporary hangars.

[0017] 2. After transporting the support cabin to the designated location, the base is fixed to the ground. The drive arm rotates around the base, causing the last arch frame connected to the drive arm to move. The swing arm guides the last arch frame, and the force generated causes the last arch frame to rotate around the base. At the same time, the swing arm swings around the base with the arch frame, causing several arch frames on the swing arm to swing together. When the ropes between adjacent arch frames are taut, the arch frames will rotate on the swing arm and the fixed arm until the last arch frame contacts the ground. At this time, the ropes between each adjacent arch frame are taut. Then, the tent fabric is laid on several arch frames, thereby realizing the rapid deployment and closure of the support cabin. The steps for setting up the support cabin are relatively simple, meeting the needs of quickly setting up a temporary hangar. The location of the temporary hangar can be flexibly arranged to keep it in good condition for subsequent missions.

[0018] 3. The overall arch frame can be made of steel, which, combined with the arch frame's good compressive strength, improves the support cabin's resistance to wind and snow loads, enhances the overall stability of the temporary hangar, and provides protection for helicopters parked in the support cabin, ensuring they are in good condition for subsequent missions.

[0027] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0028] A type of detachable ellipsoidal support module, such as Figure 1-4As shown, the tent includes two bases 1 connected to the ground, a tent fabric, and several arch frames 2. A pivot 3 is rotatably connected to each base 1. A fixed arm 4 and a swing arm 5 are mounted on the pivot 3. Several arch feet 6 are rotatably connected to the fixed arm 4 and the swing arm 5, respectively. The two ends of the central arch frame 2 are rotatably connected to the pivot 3, while the two ends of the remaining arch frames 2 are connected to the arch feet 6. In the initial state, the fixed arm 4 and the swing arm 5 are located on one side of the base 1, with the fixed arm 4 positioned above the base 1. Several arch frames 2 are placed parallel to each other on one side of the base 1, with the two ends of the central arch frame 2 connected to the pivot 3. The remaining arch frames 2 are rotatably connected, with their ends connected to the fixed arm 4 and the arch feet 6 on the swing arm 5 respectively. Then, the last arch frame 2 connected to the swing arm 5 is rotatably connected to one end of the drive arm 8. At this time, since several arch frames 2 are stacked in parallel, it is convenient to transport the support cabin to various places, improving the convenience of transporting temporary hangars. A pull rope 7 is provided between adjacent arch frames 2. The drive arm 8 is rotatably connected to the base 1. The last arch frame 2 connected to the swing arm 5 is rotatably connected to the drive arm 8. The drive arm 8 drives the arch frame 2 to rotate around the pivot 3, and drives the swing arm 5 and the remaining arch frames 2 to rotate around the pivot 3. After the support cabin is transported to the designated location, the base 1 is fixed to the ground. The drive arm 8 rotates around the base 1, causing the last arch 2 connected to the drive arm 8 to move. The swing arm 5 guides the last arch 2, generating a force that causes the last arch 2 to rotate around the base 1. Simultaneously, the swing arm 5 swings with the arch 2 around the base 1, causing several arches 2 on the swing arm 5 to swing together. When the tension ropes 7 between adjacent arches 2 are taut, the arches 2 will rotate on the swing arm 5 and the fixed arm 4 until the last arch 2 contacts the ground. At this point, a tension rope is set between each adjacent arch 2. Some of the ropes 7 are taut. Then, the tent fabric is laid on several arch frames 2, which enables the support cabin to be quickly deployed and closed. The steps for setting up the support cabin are relatively simple, meeting the need for rapid construction of temporary hangars. The location of the temporary hangar can be flexibly arranged to keep it in good condition for subsequent missions. In addition, the overall arch frame 2 can be made of steel, which, combined with the good compressive strength of the arch frame 2, improves the support cabin's resistance to wind and snow loads, enhances the overall stability of the temporary hangar, and provides protection for helicopters parked in the support cabin to keep them in good condition for subsequent missions.

[0029] Preferred, such as Figure 1 and Figure 2 As shown, several arch frames 2 form a truncated ellipsoidal structure, and the tent cover is set on the truncated ellipsoidal structure. The support cabin of the truncated ellipsoidal structure is designed with a streamlined shape, which can improve the support cabin's resistance to wind and snow loads, making the overall structure of the temporary hangar more stable, and providing protection for the helicopters parked in the support cabin so as to keep them in good condition for subsequent missions.

[0030] Preferred, such as Figure 5 As shown, the arch frame 2 includes several arc-shaped rods 9, and connecting parts 10 are provided between the arc-shaped rods 9, so that the arch frame 2 can be disassembled into several parts, which facilitates the transportation of temporary hangars under various conditions.

[0031] Preferred, such as Figure 5 and Figure 6 As shown, the arc-shaped rod 9 has inserts 11 at both ends, and the connector 10 has slots 12 at both ends that engage with the inserts 11. The connector 10 has several bolts 13 that contact the inserts 11. The inserts 11 at the ends of the arc-shaped rod 9 are inserted into the slots 12 of the connector 10, and the bolts 13 are rotated so that their ends contact the inserts 11. The friction generated by the contact between the bolts 13 and the inserts 11 restricts the movement of the inserts 11 relative to the connector 10, thereby achieving a detachable connection between the arc-shaped rod 9 and the connector 10. This allows the temporary hangar to be disassembled into several parts, facilitating the transportation of the temporary hangar under various conditions.

[0032] Preferred, such as Figure 5 and Figure 6 As shown, the insert 11 has several protrusions 14, and the groove 12 has several grooves 15 that are slidably connected to the protrusions 14. These grooves guide the connection between the arc rod 9 and the connector 10, preventing the arch frame 2 from deviating from the designated track and affecting the overall formation of the truncated ellipsoidal structure of the arch frame 2, thereby improving the overall stability of the temporary hangar.

[0033] Preferred, such as Figure 3 As shown, the base 1 includes a base plate 16 and a tripod 17 mounted on the base plate 16. Specifically, the base plate 16 is made of steel plate, and counterweights are added to the base plate 16 to increase the connection between the support cabin and the ground, thereby improving the overall stability of the temporary hangar and enabling it to better withstand severe weather such as blizzards, heavy rain, and hail. This provides protection for helicopters parked in the support cabin, ensuring they are in good condition for subsequent missions. The rotating shaft 3 is rotatably mounted on the tripod 17. The stability provided by the structure of the tripod 17 ensures that the rotating shaft 3 is stably mounted on the tripod 17, thereby preventing the arch frame 2 from deviating from the designated track and affecting the overall truncated ellipsoidal structure of the arch frame 2, thus improving the overall stability of the temporary hangar.

[0034] Preferred, such as Figure 3As shown, the base plate 16 is provided with a number of long spiral piles 18. By drilling the long spiral piles 18 into the ground, the base plate 16 is firmly fixed to the ground, increasing the connection between the support cabin and the ground, thereby improving the overall stability of the temporary hangar and enabling it to better resist severe weather such as blizzards, rainstorms, and hail. This provides protection for helicopters parked in the support cabin, ensuring they are in good condition for subsequent missions.

[0035] Preferably, the tent fabric is made of Oxford cloth. After being treated with relaxation, alkali treatment, dyeing, antistatic treatment, and coating, the Oxford cloth has the advantages of being lightweight, soft to the touch, waterproof, and durable. This improves the overall stability of the temporary hangar, enabling it to better withstand severe weather such as blizzards, heavy rain, and hail, and provides protection for helicopters parked in the support cabin, so that they can be kept in good condition for subsequent missions.

[0036] Preferred, such as Figure 3 As shown, the base 1 is equipped with a reducer 19 and a motor 20. The output end of the reducer 19 is connected to the swing arm 5, and the output end of the motor 20 is connected to the input end of the reducer 19. Power is transmitted through the motor 20 and the worm gear reducer 19 to realize the deployment and closure of the protection cabin. At the same time, the reducer 19, which uses worm gear transmission, can achieve self-locking, so that the protection cabin is firmly held in any angle of opening or closing position to meet different needs under different conditions.

[0037] Example 1

[0038] This utility model provides a detachable ellipsoidal support cabin, such as Figures 1-4 As shown, in the initial state, the fixed arm 4 and the swing arm 5 are located on one side of the base 1 and the fixed arm 4 is above the base 1. Several arch frames 2 are placed parallel to one side of the base 1. At the same time, the two ends of the middle arch frame 2 are rotatably connected to the rotating shaft 3, and the two ends of the remaining arch frames 2 are connected to the arch feet 6 provided on the fixed arm 4 and the swing arm 5, respectively. Then, the last arch frame 2 connected to the swing arm 5 is rotatably connected. At this time, since several arch frames 2 are stacked together in parallel, it is convenient to transport the support cabin to various places and improve the convenience of transporting temporary hangars.

[0039] After the support cabin is transported to the designated location, the base 1 is fixed to the ground. The drive arm 8 rotates around the base 1, which moves the last arch 2 connected to the drive arm 8. The swing arm 5 guides the last arch 2, and the force generated causes the last arch 2 to rotate around the base 1. At the same time, the swing arm 5 swings around the base 1 with the arch 2, causing several arches 2 on the swing arm 5 to swing together. When the ropes 7 between adjacent arches 2 are taut, the arches 2 will rotate on the swing arm 5 and the fixed arm 4 until the last arch 2 contacts the ground. At this time, the ropes 7 between each adjacent arch 2 are taut. Then, the tent fabric is laid on several arches 2, so that the support cabin can be quickly deployed and closed. The steps of setting up the support cabin are relatively simple, which meets the needs of quickly setting up a temporary hangar. The location of the temporary hangar can be flexibly arranged to keep it in good condition for subsequent tasks.

[0040] In addition, the overall arch frame 2 can be made of steel, which, combined with the good compressive strength of the arch frame 2 itself, improves the wind and snow load resistance of the support cabin, enhances the overall stability of the temporary hangar, and provides protection for helicopters parked in the support cabin, so as to keep them in good condition for subsequent missions.

[0041] Example 2

[0042] Based on Example 1, such as Figure 1 and Figure 2 As shown, several arch frames 2 form a truncated ellipsoidal structure, and the tent cover is set on the truncated ellipsoidal structure. The support cabin of the truncated ellipsoidal structure is designed with a streamlined shape, which can improve the support cabin's resistance to wind and snow loads, making the overall structure of the temporary hangar more stable, and providing protection for the helicopters parked in the support cabin so as to keep them in good condition for subsequent missions.

[0043] In addition, the tent fabric is made of Oxford cloth. After being treated with relaxation, alkali treatment, dyeing, antistatic treatment, and coating, Oxford cloth has the advantages of being lightweight, soft to the touch, waterproof, and durable. It can improve the overall stability of the temporary hangar and make it better able to withstand severe weather such as blizzards, heavy rain, and hail. It also provides protection for helicopters parked in the support cabin, so that they can be kept in good condition for subsequent missions.

[0044] Example 3

[0045] Based on Example 1, such as Figure 5 and Figure 6 As shown, the arch frame 2 includes several arc-shaped rods 9, and connecting parts 10 are provided between the arc-shaped rods 9, so that the arch frame 2 can be disassembled into several parts, which facilitates the transportation of temporary hangars under various conditions.

[0046] When assembling the arch frame 2, the insert 11 at the end of the arc-shaped rod 9 is inserted into the groove 12 of the connector 10. At the same time, the several protrusions 14 on the insert 11 are slidably connected to the several grooves 15 in the groove 12, which guides the connection between the arc-shaped rod 9 and the connector 10, preventing the arch frame 2 from deviating from the designated track and affecting the overall truncated ellipsoidal structure of the arch frame 2, thus improving the overall stability of the temporary hangar. Then, the bolt 13 is rotated so that its end contacts the insert 11. The friction generated after the bolt 13 contacts the insert 11 restricts the movement of the insert 11 relative to the connector 10, thereby realizing the detachable connection between the arc-shaped rod 9 and the connector 10. This allows the temporary hangar to be disassembled into several parts, facilitating the transportation of the temporary hangar under various conditions.

[0047] Example 4

[0048] Based on Example 1, such as Figure 3 As shown, the base 1 includes a base plate 16 and a tripod 17 mounted on the base plate 16. Specifically, the base plate 16 is made of steel plate. By drilling long helical piles 18 into the ground and adding counterweights to the base plate 16, the base plate 16 is firmly fixed to the ground, increasing the connection between the support cabin and the ground, thereby improving the overall stability of the temporary hangar and enabling it to better withstand severe weather such as blizzards, heavy rain, and hail. This provides protection for helicopters parked in the support cabin, ensuring they are in good condition for subsequent missions. Additionally, the pivot 3 is rotatably mounted on the tripod 17. The stability provided by the tripod 17 structure ensures that the pivot 3 rotates stably on the tripod 17, thus preventing the arch frame 2 from deviating from its designated track and affecting the overall truncated ellipsoidal structure of the arch frame 2, thereby improving the overall stability of the temporary hangar.
