Description

Technical Field

[0001] The present invention relates to the technical field of tube electrothermal protection, and particularly to a tube electrothermal protection structure for a marine rocket launch pad and its usage method. Background Technique

[0002] A marine rocket launch pad refers to a way of launching rockets in the sea area using ships or offshore platforms. Marine launch platforms can be divided into two types: fixed and mobile. The advantages of marine launch are cost savings: Marine launch can utilize the speed of the Earth's rotation to reduce the consumption of rocket fuel, thereby reducing the launch cost. The mobile marine launch platform can be launched in different sea areas, increasing the flexibility and adaptability of the launch, solving the safety problem of the flight landing area in land launch, and reducing the potential threat to ground facilities and personnel.

[0003] The tube electrothermal protection device in a marine rocket launch pad is generally fixed by screws. Since seawater is easy to contact with the screws, long-term contact between the screws and seawater will cause rust cracks on the surface. The rust cracks will cause the screws to get stuck inside the protection device, making it very laborious to disassemble and repair the protection device. Summary of the Invention

[0012] A linkage plate is fixedly connected to the surface of the rectangular frame. One end of the linkage plate away from the rectangular frame is fixedly connected to the surface of the protective plate.

[0013] Further, the bottom of the bent plate contacts the top of the bottom plate. One end of the push plate away from the sliding frame is inclined downward. The inner wall of the sliding frame slides on the surface of the limiting frame. One end of the linkage plate away from the rectangular frame extends above the skateboard through a through hole.

[0014] Further, the extrusion component further includes a fixed rod. The end of the fixed rod is fixedly connected to the surface of the sliding frame.

[0015] There are four arc plates, and the four arc plates are circumferentially arranged with the electric push rod as the center.

[0016] Further, there are four triangular blocks, and the four triangular blocks are located at one end where the four protective plates are close to each other.

[0020] Furthermore, a method for using the electrothermal protection structure of a pipe on an offshore rocket launch pad includes the following steps:

[0021] S1: A protection component is arranged on the surface of the groove plate. The protection component is used to protect the pipe electricity. When the pipe electricity needs to be overhauled, the protection component is started to expand outwards. At this time, the protection component will move away from each other on the surface of the sliding plate, so as to overhaul the pipe electricity structure;

[0022] S2: Start the electric push rod to push the lifting plate to move upwards. When the lifting plate moves, it drives the push plate to move upwards through the bent plate. When the push plate moves, it pushes the sliding frame to slide on the surface of the limit frame. When the limit frame slides, it drives the protection plate to move towards the outer end of the groove plate through the linkage plate;

[0023] S3: When the protection plate closes on the top of the groove plate to protect the pipe electricity, the extrusion plate will push the triangular block to move synchronously with the protection plate through the arc plate, and when the protection plate closes, it will extrude the surface of the protection plate;

[0024] S4: When the moving frame moves towards the surface of the support rod, it drives the contact rod to contact the surface of the contact plate through the stabilizing plate. After the contact rod contacts the surface of the contact plate, it will slide upwards as the moving frame moves. When the contact rod slides, it will contact the surface of the push plate, and the push plate is extruded and fixed by the contact rod.

[0025] The present invention has the following beneficial effects:

[0026] The present invention is provided with a protection component on the surface of the groove plate to protect the pipe electricity with the protection component. When the pipe electricity needs to be overhauled, the protection component is started to expand outwards. At this time, the protection component will move away from each other on the surface of the sliding plate, so as to overhaul the pipe electricity structure. An extrusion component is arranged on the top of the bottom plate, and the extrusion component is located at one end where the protection plates are close to each other. When the protection plates contract, the extrusion component can extrude the protection component to improve the stability of the protection plate when protecting the pipe electricity. A stabilizing component is arranged below the groove plate, and the stabilizing component can extrude the protection component to improve the stability of the protection component after closing.

[0027] When the present invention needs to overhaul the pipe electricity, start the electric push rod to push the lifting plate to move upwards. When the lifting plate moves, it drives the push plate to move upwards through the bent plate. When the push plate moves, it pushes the sliding frame to slide on the surface of the limit frame. When the limit frame slides, it drives the protection plate to move towards the outer end of the groove plate through the linkage plate, improving the convenience of overhauling the pipe electricity. The protection plate slides on the surface of the sliding plate through the chute, improving the stability of the protection plate when moving and avoiding the situation that the protection plate tilts and gets stuck when opening and closing.

[0028] When the sliding frame of the present invention moves, it pushes the connecting plate to move through the fixed rod. When the connecting plate moves, it drives the pressing plate to move through the telescopic rod. At this time, the triangular block can move synchronously away with the protection plate. When the protection plate closes on the top of the groove plate to protect the pipe electricity, the pressing plate will push the triangular block to move synchronously with the protection plate through the arc plate, and when the protection plate closes, it will squeeze the surface of the protection plate, improving the stability of the protection plate when protecting the pipe electricity.

[0029] When the lifting plate of the present invention moves downward, the lifting plate pushes the moving frame to slide on the surface of the positioning plate through the stress plate. When the moving frame moves towards the surface of the support rod, it pushes the contact rod to contact the surface of the contact plate through the stabilizing plate. After the contact rod contacts the surface of the contact plate, it will slide upward with the movement of the moving frame. When the contact rod slides, it will contact the surface of the push plate, and use the contact rod to squeeze and fix the push plate, avoiding the situation of sliding separation when the protection plate protects the pipe electricity.

[0030] Of course, it is not necessary for any product implementing the present invention to simultaneously achieve all the above-mentioned advantages. BRIEF DESCRIPTION OF THE DRAWINGS

6. The usage method of an electrothermal protection structure for a sea-based rocket launch pad according to claim 5, characterized in that, Including the following steps: S1: A protection component (2) is arranged on the surface of the groove disc (6). The protection component (2) is used to protect the tube electricity. When it is necessary to repair the tube electricity, the protection component (2) is started to expand outwards. At this time, the protection component (2) will move away from each other on the surface of the skateboard (7) so as to repair the tube electricity structure. S2: The electric push rod (15) is started to push the lifting plate (12) to move upwards. When the lifting plate (12) moves, it drives the push plate (17) to move upwards through the bent plate (16). When the push plate (17) moves, it pushes the sliding frame (14) to slide on the surface of the limiting frame (18). When the limiting frame (18) slides, it drives the protection plate (10) to move towards the outer end of the groove disc (6) through the linkage plate (11). S3: When the protection plate (10) closes on the top of the groove disc (6) to protect the tube electricity, the extrusion plate (22) will push the triangular block (20) to move synchronously with the protection plate (10) through the arc plate (21), and when the protection plate (10) closes, the surface of the protection plate (10) is extruded. S4: When the moving frame (30) moves towards the surface of the support rod (5), the contact rod (33) is pushed by the stabilizing plate (34) to contact the surface of the contact plate (35). After the surface of the contact rod (33) contacts the surface of the contact plate (35), it will slide upwards along with the movement of the moving frame (30). When the contact rod (33) slides, it will contact the surface of the push plate (17), and the push plate (17) is extruded and fixed by the contact rod (33).
