Description

Technical Field

[0001] The invention belongs to the technical field of launching large-scale aerostats, and in particular relates to an openable and closable boathouse. Background Art

[0002] At present, the process of launching a large aerostat is generally to first tie the airship capsule to the pull ring of the anchor with a mooring rope in a closed boathouse, inflate and check to confirm that it is correct, then transfer the mooring rope from the anchor to a special anchoring vehicle or a giant integrated launching vehicle, open the door of the boathouse at an appropriate time, and use the anchoring vehicle or the integrated launching vehicle to transport the large aerostat to the outside of the boathouse for launch. The existing launching technology has the following defects:

[0003] First of all, boathouses are generally giant fixed buildings with steel trusses or grid structures and skins, with huge movable doors at one or both ends, which take a long time to open and close. Of course, there are other structural forms of boathouses in the prior art. For example, the patent with publication number CN109693806A discloses a tethered balloon anchoring platform. The patent provides a technical solution for opening a window on the top of the boathouse, which is very difficult to implement. The movable skylight near the top must move as a whole, which requires the steel structure of the lower boathouse to be very strong in order to withstand the huge lateral force generated when the movable skylight is reversed; and the open area of ​​the skylight is limited, and the airship is very susceptible to scratches caused by the wind during the release process. In addition, the patents with publication numbers CN109850115A, US8910905B2, and CN106170441B also introduce several vehicle-mounted small airship release devices. It can be seen from their technical solutions that these release devices are obviously unable to meet the release of large and medium-sized airships.

[0004] Secondly, when transporting large aerostats, the requirements for the driving speed and instantaneous position accuracy of the anchoring vehicle are extremely high. If the position deviation is too large, the airship capsule will be directly torn apart. Therefore, large aerostats are generally not released by separate anchoring vehicles. Although the giant integrated launch vehicle overcomes all the shortcomings of the separate anchoring vehicle launch system, due to the huge body of the integrated launch vehicle, it requires a very wide dedicated road, which is obviously difficult to meet in mountainous areas and islands.

[0005] In order to ensure the smooth and reliable launch of large aerostats, especially in mountainous areas and islands, a launch technology that occupies a small area and is safe and reliable is urgently needed, so improvements are proposed. Summary of the invention

[0012] Furthermore, auxiliary support wheels are provided at the bottom of the 1 / 4 ellipsoidal dome head at the front end of the movable front dome and / or rear dome in the translationally movable opening and closing boathouse.

[0013] Furthermore, the wheels installed at the bottom of the movable front dome and / or rear dome are driven by an electric motor or a hydraulic motor, and the control system thereof has a speed regulating function.

[0015] Furthermore, the trusses of the left dome and the right dome in the split-petal retractable boathouse are composed of multiple sections of trusses connected in sequence, and each section of the truss is connected to the foundation through a hinge I and is equipped with at least one set of self-driving push rods.

[0016] Furthermore, each set of the self-driven push rods adopts an electric push rod, and the electric push rod adopts a trapezoidal thread screw pair or a planetary ball screw with strong load capacity.

[0025] 4. The split-petal opening and closing boathouse in this scheme occupies a small area and does not require the construction of a wide dedicated road outside the boathouse. It is particularly suitable for places where there is a lack of wide space, such as mountainous areas, islands and ships. In addition, the opening is large, providing a large enough opening for the launch of the aerostat.

[0026] 5. In this scheme, the movable dome of the horizontally movable opening and closing boathouse is moved by the cooperation of tracks and wheels, with a simple structure and reliable control. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] Please see attached Figure 1-6 Describe the embodiments of the present invention in detail:

[0038] Embodiment 1: This embodiment describes in detail the structure of a horizontally movable openable boathouse 1, see Figure 1-3 As shown:

[0039] The translational opening and closing boathouse 1 includes a front dome 11 and a rear dome 12, at least one of the front dome 11 and the rear dome 12 is a movable dome. In this embodiment, the front dome 11 is connected to the foundation through a movable load-bearing mechanism, and the rear dome 12 is fixedly connected to the foundation. The rear dome 12 is directly a 1 / 4 ellipsoidal dome head 13 structure, and the front end of the front dome 11 is also a 1 / 4 ellipsoidal dome head 13 structure. The front dome 11 and the rear dome 12 are composed of an internal metal truss or grid and an external protective skin. The front dome 11 and the rear dome 12 move horizontally relative to each other to achieve closure and form an integral boathouse, and the front dome 11 and the rear dome 12 move back to back relative to each other to achieve the opening of the boathouse.

[0040] Among them, the movable structure between the front dome 11 and the foundation is: wheels 15 are installed at the bottom of both sides of the front dome 11, and the wheels 15 are attached to two parallel railways 14. Some or all of the wheels 15 are driving wheels with a power device and are used to drive the movable front dome 11 to move along the railway 14 as a whole.

[0041] Preferably, the length of the two railroads 14 of the translational opening and closing boathouse 1 is greater than the length of the front dome 11. The wheels 15 installed at the bottom of the movable front dome 11 are driven by an electric motor or a hydraulic motor, and the control system thereof has a speed regulating function.

[0042] The joint ends of the front dome 11 and the rear dome 12 when closed are provided with a rainproof structure 3 for protecting against wind and rain, a sealing buffer structure 5 for buffering and sealing, and a locking mechanism 4 for keeping the two domes stably closed. A flexible protective curtain is provided at the bottom of the front dome 11.

[0043] The front dome 11 and the rear dome 12 are both provided with good grounding and lightning protection devices.

[0044] Working process: Normally, the movable front dome 11 is parked at the left end, and combined with the fixed rear dome 12 to form a closed windproof space. The staff can enter through the small door set at the bottom of the rear dome 12 to inflate the aerostat and perform various tests. When the aerostat needs to be released, the front dome 11 can be moved to the front of the right side to fully open the space above the airship, and all the tethers that bind the aerostat are released simultaneously, and the aerostat will be successfully launched.

[0045] Since there are railways 14 only on both sides below the front dome 11, the suspended span at the bottom of the 1 / 4 ellipsoidal dome head 13 of the front dome 11 is relatively large. If the structural strength is difficult to ensure, some auxiliary support wheels 16 can be installed at the bottom of the 1 / 4 ellipsoidal dome head 13, and the necessary road hardening can be performed on the walking paths of these auxiliary support wheels 16.

[0046] Example 2: This example describes in detail the structure of a split-petal opening and closing boathouse 2, see Figure 4-5 As shown:

[0047] The split-petal opening and closing boathouse 2 comprises a left dome 21, a right dome 22 and a self-driving push rod 24. The trusses of the left dome 21 and the right dome 22 in the split-petal opening and closing boathouse 2 are composed of multiple sections of trusses connected in sequence. Each section of the truss is connected to the foundation 23 through a hinge Ⅰ26 and is equipped with at least one set of self-driving push rods 24. The left dome 21 and the right dome 22 each realize angle change through the corresponding self-driving push rods 24. The left dome 21 and the right dome 22 are constrained by the corresponding self-driving push rods 24 and the hinge Ⅰ26 anchored on the foundation 23. The expansion and contraction amount of the self-driving push rods 24 is changed to realize the change of the opening and closing angle of the dome. When the self-driving push rods 24 drive the corresponding left dome 21 and the right dome 22 to flip toward each other, they are closed to form a closed dome-type boathouse. When the self-driving push rods 24 drive the corresponding left dome 21 and the right dome 22 to flip back to back, the boathouse is opened.

[0048] Among them, the first implementation method of the self-driving push rod 24 is: each set of the self-driving push rod 24 adopts an electric push rod, and the electric push rod adopts a trapezoidal thread screw pair or a planetary ball screw with strong load capacity. The telescopic end of the electric push rod is connected to the truss through a hinge II 27, and the base of the electric push rod is fixed on the foundation 23 through a hinge III 28; each set of the electric push rod also includes a motor and a reducer, and the input shaft of the reducer is a double-axis extension and the reducer input shafts of all the electric push rods of each section of the truss on one side are connected through a transmission shaft and a universal joint or an elastic connector. The motor and the reducer are directly driven by a belt or gear, a toothed chain drive or a special input shaft of the reducer. In this embodiment, all the reducer input shafts on each side are connected into one by a transmission shaft and a coupling to ensure the synchronous movement of the lifting rod; the distributed motor drive greatly improves the safety margin of the system, and even if some motors fail, it will not affect the overall movement of the truss.

[0049] Implementation method 2 of the self-driving push rod 24: The self-driving push rod 24 uses a hydraulic cylinder. Each section of the truss is equipped with at least one set of hydraulic cylinders. The oil circuit of each hydraulic cylinder is connected in parallel. A one-way valve is provided in the hydraulic pipeline of the hydraulic cylinder to prevent the truss from losing control when the hydraulic system suddenly loses pressure.

[0050] The joint ends of the left dome 21 and the right dome 22 when closed are provided with a rainproof structure 3 for protecting against wind and rain, a sealing buffer structure 5 for buffering and sealing, and a locking mechanism 4 for keeping the two domes stably closed.

[0051] Embodiment 3: In the above-mentioned embodiments 1 and 2, the specific structures of the rainproof structure 3, the sealing buffer structure 5 and the locking mechanism 4 at the joint ends of the two domes in the translational opening and closing type boathouse 1 or the split-petal opening and closing type boathouse 2 are as follows: Figure 6 As shown:

[0052] The combined end of the two domes when the boathouse is closed includes an end plate I 31 and an end plate II 32 respectively arranged on the two domes. Among them, the rainproof structure 3 includes a rainproof cover 33 arranged on the outer edge of the end plate I 31, the bottom of the rainproof cover 33 bent on one side is fixedly connected to the outer side of the end plate I 31, and the other side of the rainproof cover 33 is bent downward to form a drip edge 34 that covers the end plate II 32, and the outer edge of the end plate II 32 protrudes from the skin to form a water-proof edge, which can block the rainwater that may drift over. The locking mechanism 4 includes a lock hook 42 and a reduction motor 41, and the lock hook 42 is arranged on one side of the inner side of one of the two domes combined, and the reduction motor 41 has a self-locking function. When the boathouse is closed, the reduction motor 41 drives the lock hook 42 to buckle the two parts of the dome; when the boathouse needs to be opened, the reduction motor 41 drives the lock hook 42 to disengage. The sealing buffer structure 5 uses a sealing buffer pad arranged between the end plate I 31 and the end plate II 32.

[0053] In the present invention, since the boathouse adopts a translational opening and closing boathouse structure or a split-petal opening and closing boathouse structure, when launching, only the top of the boathouse needs to be opened to launch and recover the aerostat, which eliminates the traditional transfer and transportation processes, shortens the launching time, avoids possible intermediate failures, and improves work efficiency.

[0054] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

[0055] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
