Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of flow guide trench cover plates, and more particularly to a flow guide trench cover plate. BACKGROUND

[0002] The flow guide trench is used to guide the flame emitted during the launch of a rocket to another place to prevent high-temperature flame from damaging the rocket and ground facilities. The flow guide trench contains a large amount of water, and the white water mist we see is formed when high-temperature flame meets water. The flow guide trench cover plate is located on the inner side of the flow guide trench and is convenient to open or close, so as to control the working state of the flow guide trench.

[0003] According to the search, the Chinese patent with the publication number CN219711685U discloses an automatic opening and closing cover plate of a flow guide trench, which comprises a cover plate structure arranged directly above the flow guide trench opening. The cover plate structure comprises a frame, a plurality of movable plate structures and a plurality of lifting mechanisms. At least one fixed plate is fixed to the opening edge of the flow guide trench. The lifting mechanism is fixedly connected to the bottom of the frame. The frame is used to limit the fixed plate and the movable plate structure. When the frame is lowered, the fixed plate is located at the end inside the frame. When the frame is raised, the movable plate structure is located above the fixed plate and can be translated and overlapped directly above the fixed plate. The movable plate structure can be translated in the frame to cover or open the flow guide trench opening. The structure of the utility model is reasonable. The flow guide trench opening can be closed or opened as needed, improving the convenience of use. The frame cooperates with the movable plate structure to improve the convenience of operation. The frame can also prevent deformation during later use, which is beneficial to improve the use safety and stability.

[0004] According to the related technology in the above, the applicant believes that the way of opening and closing the movable plate is not convenient enough, and it is difficult to simply and conveniently open or close the movable plate when needed, and the practicality is not high. Therefore, we propose a flow guide trench cover plate. Invention content

[0036] The following will be described in detail with reference to the drawings of the embodiments of the present application. Figures 1-6 The present application will be further described in detail.

[0037] Please refer to Figures 1-6 A guide groove cover plate, comprising a base module 100 and a cover plate module 200, the base module 100 comprises a launching platform 110, the top of the launching platform 110 is provided with two mounting assemblies 120, the cover plate module 200 is arranged on the launching platform 110, the cover plate module 200 comprises a cover plate assembly 210 arranged inside the launching platform 110, the cover plate assembly 210 and the launching platform 110 are provided with a placing assembly 220, the cover plate assembly 210 and the top of the launching platform 110 are provided with an auxiliary assembly 230, the cover plate assembly 210 comprises a gas exhaust guide hole 211 opened in the launching platform 110, the inner side of the gas exhaust guide hole 211 is rotatably connected with four cover plate bodies 212, and the four cover plate bodies 212 are mutually adhered, and the bottom of each cover plate body 212 is provided with two electric push rods 213.

[0038] The setting of the gas exhaust hole 211 can meet the needs of the core first stage and double booster gas exhaust, the setting of the cover plate body 212 can close the gas exhaust hole 211 when it is idle, the setting of the electric push rod 213 can drive the cover plate body 212 to open or close, so that the cover plate structure can be opened or closed simply and conveniently when needed, and the practicability is improved. The setting of the installation assembly 220 facilitates the installation of the cover plate assembly 210, and the setting of the auxiliary assembly 230 enables the cover plate body 212 to rotate.

[0039] The installation assembly 220 includes eight communication grooves 222 arranged on the inner walls of the gas exhaust hole 211, and eight installation grooves 221 are arranged at the bottoms of the eight communication grooves 222. The eight installation grooves 221 are in communication with the eight communication grooves 222, and the cover plate assembly 210 further includes eight mounting plates 214 fixedly connected to the inner sides of the eight installation grooves 221. The tops of the eight mounting plates 214 are fixedly connected with first U-shaped blocks 215, and the interiors of the eight first U-shaped blocks 215 are rotatably connected with first rotating blocks 216. The cover plate assembly 210 further includes eight second U-shaped blocks 218 fixedly connected to the bottoms of the four cover plate bodies 212, and the interiors of the eight second U-shaped blocks 218 are rotatably connected with second rotating blocks 217. The output ends of the eight electric push rods 213 are fixedly connected with the bottoms of the eight second rotating blocks 217, and the bottoms of the eight electric push rods 213 are fixedly connected with the tops of the eight first rotating blocks 216.

[0040] By starting the electric push rod 213, the electric push rod 213 can pull the second U-shaped block 218 through the second rotating block 217, so that the second rotating block 217 can rotate in the interior of the second U-shaped block 218, thereby pulling the cover plate body 212 to open downward. At this time, the angle and position of the electric push rod 213 will deviate according to the opening of the cover plate body 212, thereby driving the first rotating block 216 to rotate in the interior of the first U-shaped block 215, and facilitating the comprehensive opening of the cover plate body 212.

[0041] The auxiliary assembly 230 includes four sets of hinges 231 arranged between the tops of the four cover plate bodies 212 and the top of the launch platform 110.
