Description

Technical Field

[0001] This utility model relates to the technical field of fuel refueling control devices, and in particular to a launch platform oxidizer refueling control device. Background Art

[0002] In the field of space launches, the precise loading of oxidizers is a crucial step in ensuring the successful execution of launch missions. Oxidizing oxidizers are an important component of propellants, and their loading process demands extremely high precision and safety. Traditional oxidizer loading devices typically require manual intervention or simple mechanical control, which, while fulfilling basic functions, often suffer from problems such as insufficient loading precision, low efficiency, and potential safety hazards. Especially on modern launch platforms, the increased complexity of missions places even higher demands on the automation and precision of oxidizer loading devices.

[0003] Current technologies for oxidizer loading control devices still have significant design flaws. Firstly, traditional delivery systems are prone to discontinuous oxidizer delivery due to unstable pressure or backflow issues, affecting the accuracy of dosage control. Furthermore, improper operation during oxidizer delivery and loading can easily lead to excessive residue, resulting in waste and increasing the burden of equipment cleaning and the risk of environmental pollution. Moreover, existing devices lack adaptability, failing to be compatible with different specifications of oxidizer storage tanks and fuel tanks, limiting their widespread application. Therefore, there is an urgent need for an oxidizer loading control device that can achieve precise quantitative delivery, effectively prevent backflow, improve loading efficiency, and minimize residue to meet the needs of modern launch platforms.

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a control device for the refueling of oxidizing combustion aids on a launch platform.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a launch platform oxidizer injection control device, comprising: a launch platform body, a base fixedly connected to the lower end of the launch platform body, a control valve connected to the outer wall of one side of the base, an input pipe fixedly connected to one side of the control valve, a storage box connected to one side of the input pipe, a first suction pipe fixedly connected to the upper end of one side of the storage box, a one-way valve fixedly connected to one side of the inner wall of the first suction pipe, a dosing box fixedly connected to the outer wall of one side of the upper end of the storage box, a transmission pipe fixedly connected to the outer wall of one side of the dosing box, and a transmission mechanism connected to one side of the upper end of the storage box;

[0013] In a preferred embodiment, the lower ends of both the storage box and the support are fixedly connected to the bottom of the inner wall of the launch platform body.

[0033] Example 1

[0034] like Figure 1-6As shown, this utility model provides a technical solution: a launch platform oxidizer injection control device, comprising: a launch platform body 1, a base 5 fixedly connected to the lower end of the launch platform body 1, a control valve 6 connected to the outer wall of one side of the base 5, an input pipe 7 fixedly connected to one side of the control valve 6, a storage tank 8 connected to one side of the input pipe 7, a first suction pipe 9 fixedly connected to the upper end of one side of the storage tank 8, a one-way valve 10 fixedly connected to one side of the inner wall of the first suction pipe 9, the one-way valve 10 including a sealing block 101, a fixing block 102 fixedly connected to one side of the sealing block 101, a limit block 103 fixedly connected to the side of the fixing block 102 away from the sealing block 101, a dosage box 11 fixedly connected to one side of the outer wall of one side of the upper end of the storage tank 8, a transmission pipe 12 fixedly connected to one side of the outer wall of one side of the dosage box 11, a one-way valve 10 provided on one side of the inner wall of both the first suction pipe 9 and the transmission pipe 12, and a transmission mechanism 13 connected to one side of the upper end of the storage tank 8;

[0035] The transmission mechanism 13 includes a motor 131 connected to one side of the inner wall of the storage box 8. A rotating rod 132 is connected to the upper end of the motor 131. A rotating block 133 is fixedly connected to the upper end of the rotating rod 132. A connecting member 134 is movably connected to the outer wall of one side of the upper end of the rotating block 133. A fixing member 135 is movably connected to the side of the connecting member 134 away from the rotating block 133. A connecting rod 136 is fixedly connected to one side of the fixing member 135. A limiting member 137 is movably connected to one side of the outer wall of the connecting rod 136. A push plate 138 is fixedly connected to one side of the connecting rod 136. The push plate 138 on one side of the connecting rod 136 is located on one side of the inner wall of the dosing box 11 and is slidably connected. A sleeve 139 is movably connected to one side of the outer wall of the rotating rod 132. The lower end of the limiting member 137 is fixedly connected to the upper outer wall of the storage box 8. The lower end of the sleeve 139 is fixedly connected to the upper outer wall of the storage box 8.

[0036] In this embodiment, a launch platform body 1 is designed, with a base 5 at the lower end of the launch platform body 1. A control valve 6 and an input pipe 7 are provided on one outer wall of the base 5. A storage tank 8 is connected to one inner wall of the base 5. The input pipe 7 is correspondingly connected to the storage tank 8. Therefore, by operating the input pipe 7, the control valve 6 can deliver the combustion accelerant to the storage tank 8 for storage. A motor 131 is provided on one inner wall of the storage tank 8. A rotating block 133 is connected to the upper end of the motor 131 via a rotating rod 132. A connector 134 is connected to one side of the upper end of the rotating block 133, and a fixing member 135 is connected to the other side of the connector 134. The fixing member 135 is located on one inner wall. The connecting rod 136 is fixedly connected to the inner wall of the dosing chamber 11, and a push plate 138 is fixedly connected to it. Therefore, when the motor 131 is started, the motor 131 will drive the rotating rod 132 and the rotating block 133 to rotate. At this time, the connecting member 134 will rotate on the centrifugal shaft, and then the connecting rod 136 will move laterally through the fixing member 135. Subsequently, the push plate 138 will move laterally on the inner wall of the dosing chamber 11, thereby changing the pressure on one side of the inner wall of the dosing chamber 11. A sleeve 139 is provided on the outer wall of the rotating rod 132, which can limit its rotation. When vibration occurs, a limiting member 137 is provided on one side of the upper end of the storage tank 8. The limiting member 137 is movably connected to the outer wall of the connecting rod 136, which can also play a limiting role to prevent it from shifting. The dosing tank 11 is connected to the inner wall of the storage tank 8 through the first suction tube 9. Therefore, when the push plate 138 moves towards the control valve 6, a negative pressure is formed inside the dosing tank 11. At this time, the combustion accelerant stored in the storage tank 8 will be absorbed into the dosing tank 11. Then the push plate 138 moves in the opposite direction and can be pushed into the fuel tank 14 for use through the transmission tube 12. One-way valves 10 are provided on one side of the inner wall of the transmission tube 12 and the first suction tube 9. Valve 10 includes a sealing block 101 made of rubber and bendable. A limiting block 103 is connected to one side of the sealing block 101 via a fixing block 102. The limiting block 103 is fixedly connected to one side of the inner wall of the transmission tube 12 and the first suction tube 9. When the first suction tube 9 delivers the combustion accelerator to the dosing tank 11, the sealing block 101 bends upward, and the combustion accelerator enters the dosing tank 11. When the delivery is completed, the sealing block 101 is prevented from bending downward by the limiting block 103, so the combustion accelerator cannot flow back into the storage tank 8. The transmission tube 12 operates on the same principle, thus enabling quantitative dispensing.

[0037] Example 2

[0038] like Figure 1-3As shown, a mounting bracket 2 is fixedly connected to one outer wall of the upper end of the launch platform body 1. An air pump 3 is fixedly connected to one outer wall of the upper end of the launch platform body 1. An inlet pipe 4 is connected to one outer wall of the air pump 3. A second suction pipe 15 is connected to the lower end of the air pump 3. A fuel tank 14 is connected to the lower end of the second suction pipe 15. One side of the fuel tank 14 is fixedly connected to one outer wall of the dosing box 11 through a transmission pipe 12. A bracket 16 is fixedly connected to one outer wall of the fuel tank 14. The lower ends of the storage box 8 and the bracket 16 are both fixedly connected to the bottom of the inner wall of the launch platform body 1.

[0039] In this embodiment, a launch platform body 1 is provided, and a fixing frame 2 is fixedly connected to the outer wall of one side of the upper end of the launch platform body 1. An air pump 3 is also provided on the outer wall of the upper end of the launch platform body 1, and an inlet pipe 4 is connected to one side of the air pump 3. A second suction pipe 15 is connected to the lower end of the air pump 3. The second suction pipe 15 extends to the lower end of the launch platform body 1 and is fixedly connected to a fuel tank 14 provided at the bottom of the inner wall of the base 5. Therefore, when the metered oxidizing combustion aid is delivered into the fuel tank 14, the launch platform can be activated. Air pump 3 draws the oxidizer from fuel tank 14 through second suction tube 15 and delivers it to the launcher through inlet tube 4, thus completing the refueling operation. The lower end of second suction tube 15 extends to the bottom of the inner wall of fuel tank 14, which can further draw the oxidizer in second suction tube 15 to avoid leaving residue that could cause inaccurate refueling dosage. A bracket 16 is provided at the lower end of the outer wall of fuel tank 14. Fuel tank 14 is fixedly connected to the inner wall of base 5 through bracket 16, which can play a role in fixation.

[0040] Working principle:

[0041] like Figure 1-6 As shown, the device, through the coordinated operation of components such as the base 5, storage tank 8, motor 131, rotating rod 132, and pusher plate 138, ensures the quantitative delivery and addition of the combustion accelerator. Specifically, the combustion accelerator is delivered to the storage tank 8 for storage via the input pipe 7 and control valve 6. When the motor 131 is started, it drives the rotating rod 132 and rotating block 133 to rotate, thereby causing the connecting piece 134 and connecting rod 136 to move laterally, which in turn drives the pusher plate 138 inside the dosage tank 11 to move laterally. The movement of the pusher plate 138 changes the pressure inside the dosage tank 11, causing the combustion accelerator to be drawn into the dosage tank 11 through the first suction pipe 9. Then, the pusher plate 138 moves in the reverse direction, delivering the combustion accelerator to the fuel tank 14 through the transmission pipe 12. One-way valves 10 are provided in the transmission pipe 12 and the suction pipe to ensure that the combustion accelerator can only flow in one direction and prevent backflow. The refueling process is completed by starting the air pump 3. The air pump 3 extracts the combustion accelerant from the fuel tank 14 through the second suction pipe 15 and delivers it to the launcher through the inlet pipe 4, thereby completing the refueling operation.
