[0002] Modern rockets require an air conditioning system for temperature control before launch. The air conditioning interface is located in the fairing area of ​​the rocket body. At the moment of rocket ignition or within a set time before launch, the air conditioning pipe connector must be disconnected from the rocket body.

[0003] The air conditioning connection of the traditional launch vehicle fairing needs to be achieved manually, and the launch vehicle is passively detached during launch. The buckle cover connector may collide with other parts. If for some reason it needs to be reconnected to provide air conditioning to the fairing, the operation is inconvenient and there is a risk of casualties to the operators. Summary of the invention

[0004] The present invention proposes an automatically docking and detaching launch vehicle fairing air conditioning connection assembly. When the present invention is applied, there is no need for manual direct docking during docking, and no need for manual detachment during detachment. The assembly has the characteristics of simple structure and low cost.

[0005] The technical solution of the present invention is as follows:

[0006] An automatically docking and detaching launch vehicle fairing air-conditioning connection assembly comprises an air-conditioning port cover and an air-conditioning connector docked with the air-conditioning port cover. The air-conditioning port cover is arranged on the inner side of the fairing. The air-conditioning port cover is an inward-turning structure and can be opened toward the inner side of the fairing. The air-conditioning connector can dock with the air-conditioning port cover from the outer side of the fairing.

[0007] As a further optimization of this solution, the air-conditioning cover includes a cover mounting piece and a cover movable plate. A mounting hole is dug at the position where the air-conditioning cover needs to be installed on the fairing. The front end of the cover mounting piece is a barrel column, which can be inserted into the corresponding mounting hole of the fairing without protruding from the outer arc surface of the fairing. The middle structure of the cover mounting piece fits the inner arc surface of the fairing, and four holes are arranged at its four corners for fixing it to the fairing. Bosses are provided inwardly on both sides of the upper rear end for limiting the position of the cover movable plate, and the middle hole is used to install a connecting shaft. A boss matching the boss of the cover mounting piece is provided on the upper side of the cover movable plate, and the cover movable plate and the cover mounting piece form an axial connection by means of the boss and the connecting shaft.

[0008] As a further optimization of the present solution, the middle protrusion at the rear end of the mouth cover mounting piece is an obliquely rounded structure.

[0009] As a further optimization of this solution, a groove is provided on the inner side of the upper boss at the rear end of the mouth cover mounting piece, a torsion spring is provided on the outer sleeve of the connecting shaft, and the lower side of the torsion spring is placed in the groove of the mouth cover mounting piece.

[0010] As a further optimization of this solution, the contact surface of the flap movable plate with the flap mounting piece is provided with a flap sealing piece installed thereon, and the flap sealing piece is in a circular ring shape and is made of a flexible material.

[0011] As a further optimization of this solution, the air-conditioning connector includes a positioning base, and two movable actuators are provided on the side of the positioning base facing the fairing.

[0013] As a further optimization of this solution, a flexible pad is provided on the side of the movable plate that contacts the air conditioner cover.

[0014] As a further optimization of this solution, a collision mechanism is provided at the front of the movable plate.

[0015] The working principle and beneficial effects of the present invention are:

[0016] When the air conditioner is needed to provide conditioned air to the fairing, the operator only needs to remotely control the air conditioning connector to dock with the air conditioning cover. The push rod on the top of the air conditioning connector can push open the inward-folding air conditioning cover, thereby realizing the pipe docking of the air conditioner and the fairing. When detaching, you only need to control the air conditioning connector to separate, and the inward-folding air conditioning cover will automatically close. When the rocket is running, the internal air pressure is much higher than the external air pressure, so the air conditioning cover can be locked with the help of air pressure.

[0017] This application does not require human operation, thus avoiding the risk of casualties; avoiding damage to the fairing; and avoiding untimely detachment or jamming that may affect the launch of the carrier rocket.

[0018] Active docking and active detachment, without the need for human operation, avoid casualties and impact on rocket launch; detect whether it is in place and detached to avoid damage to the fairing. BRIEF DESCRIPTION OF THE DRAWINGS

The air-conditioning cover is installed on the inner side of the fairing, and the air-conditioning connector is on the outer side of the fairing. They move along a common axis to achieve docking and detachment.

[0030] As the instruction manual Figure 2As shown, the air conditioner cover includes a cover mounting part and a cover movable plate. A mounting hole is dug at the position where the air conditioner cover needs to be installed on the fairing. The front end of the cover mounting part is a barrel column, which can be inserted into the corresponding mounting hole of the fairing and does not protrude from the outer arc surface of the fairing. The middle structure of the cover mounting part fits the inner arc surface of the fairing. Four holes are arranged at its four corners for fixing it with the fairing. Bosses are arranged inwardly on both sides of the upper rear end for limiting the cover movable plate. At the same time, the middle hole is used to install the connecting shaft. A boss matching the boss of the cover mounting part is arranged on the upper side of the cover movable plate. The cover movable plate and the cover mounting part are connected to each other by means of the boss and the connecting shaft. It is characterized in that the middle protrusion at the rear end of the cover mounting part is an oblique rounded structure. A groove is arranged on the inner side of the upper boss at the rear end of the mouth cover mounting piece, a torsion spring is arranged on the outer sleeve of the connecting shaft, the lower side of the torsion spring is placed in the groove of the mouth cover mounting piece, and a mouth cover seal is arranged on the contact surface of the mouth cover movable plate with the mouth cover mounting piece, and the mouth cover seal is in a circular ring shape and is made of a flexible material.

[0031] The air conditioning cover is mainly set on the inside of the fairing. The outermost part of the cover mounting part is parallel to the outer surface of the fairing. No part protrudes from the outer arc surface of the fairing. No air resistance is generated during the rocket flight. When the torsion spring can be pulled out of the air conditioning connector, the cover movable plate can be automatically closed. It has a self-sealing function and can effectively maintain the internal environment of the fairing. It has a simple structure and light weight, which can effectively improve the carrying capacity.

[0032] The front end of the mouth cover mounting part is a barrel column, which can be inserted into the corresponding hole of the fairing and does not protrude from the outer arc surface of the fairing. The middle structure fits the inner arc surface of the fairing. Four holes are arranged at its four corners for fixing it to the fairing. The middle protrusion at the rear end is an oblique rounded structure, which is used to contact the mouth cover seal, reliably seal and prevent damage to the mouth cover seal. The middle groove of the upper boss at the rear end is used to limit the axial movement of the torsion spring along the connecting shaft. The bosses on both sides of the upper rear end can limit the mouth cover movable plate. At the same time, the middle hole is used to install the connecting shaft, which can connect the mouth cover movable plate and the torsion spring as a whole to realize the rotation of the movable plate around the connecting shaft. The mouth cover movable plate is basically a flat plate structure, with a flanged boss at the front end for installing the mouth cover seal, ribs on both sides of the rear end, and the head hole for passing the connecting shaft.

[0033] The air-conditioning connector includes a positioning base, and two movable actuators are arranged on the side of the positioning base facing the fairing. A movable disk is arranged on the top of the two movable actuators, and the shape of the movable disk matches the shape of the outer side of the air-conditioning cover. An air-conditioning telescopic tube is arranged on the rear side of the movable disk, and the other end of the air-conditioning telescopic tube extends into the positioning base.

[0034] The movable plate brings the air conditioner telescopic tube out of the positioning base, and the movable actuator can push the movable plate to dock with the air conditioner cover. When separating, it is only necessary to pull out the movable plate through the movable actuator, and the air conditioner cover can be automatically closed without subsequent processing.

[0035] A contact switch is arranged at the edge of the movable plate, and a contact point matching the contact switch is arranged at the outer side of the air conditioner cover.

[0036] The contact switch can be used to position the movable plate and the air conditioner cover so that they are accurately connected.

[0037] A flexible pad is provided on one side of the movable plate in contact with the air conditioner cover. The flexible pad is a flexible material such as sponge or foam that prevents air leakage and has certain compressibility and sealing properties. One side is bonded or fixedly connected to the movable plate, and the other side is fitted to the outer arc surface of the fairing to completely cover the fairing hole.

[0038] The front part of the movable disk is provided with a butting mechanism. There is a forward extending push rod in the center of the movable disk, which is used to push open the movable plate of the cover. Interfaces connected to the movable actuator are provided on the left and right sides of the movable disk for installing the movable actuator. A contact switch mounting hole is provided on the upper side or the lower side for installing the contact switch. Two movable actuators are installed between the movable disk and the positioning base, which can realize the axial movement of the movable disk relative to the positioning base. The movable actuator can be a linear moving component such as a cylinder, an electric cylinder, or a hydraulic cylinder. One end of the air conditioner telescopic tube is fixedly connected to the movable disk and moves with the movable disk, and the other end is connected to the air conditioner outlet through the positioning base.

[0039] When docking, the moving actuator starts to move, the moving disk approaches the fairing, and the moving disk push rod pushes the cover movable plate open. When the flexible pad contacts the fairing and the contact switch gives a signal of in-position, the moving actuator stops moving, the air conditioner starts, and begins to flow air into the fairing. When disengaging, the moving actuator starts to move, the moving disk starts to move away from the fairing, and the cover movable plate closes under the action of the torsion spring, so that the contact part between the cover seal and the cover mounting part is pressed tightly to achieve complete sealing.

[0040] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
