[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0030] Embodiment 1: Figures 1 to 6 As shown, the self-elevating launch platform for launching a rocket at sea according to an embodiment of the present invention comprises:

[0031] A platform body 1, a control device 6 is installed on the top of the platform body 1, and a self-elevating device 2 is fixedly installed around the platform body 1. The platform body 1 floats on the sea surface. The lifting mechanism of the self-elevating device 2 can realize the autonomous lifting and position adjustment of the platform body 1 on the sea surface, so that the rocket can be stably launched;

[0032] A tail flame guide channel 4, which is provided on the platform body 1 and is used to guide the tail flame generated when the rocket is launched;

[0033] A protective plate 3, wherein the protective plate 3 is disposed between the tail flame guide channel 4 and the control device 6, and the protective plate 3 is movably installed in a movable groove 16 provided on the platform body 1, and the protective plate 3 can vertically rise or fall along the movable groove 16;

[0034] During operation, a rocket launching platform is fixedly installed above the tail flame guiding channel 4, and the rocket to be launched is fixedly installed on the top of the launching platform. The tail flame generated during the rocket launching process is guided to both sides through the tail flame guiding channel 4 to reduce the damage to the deck; in addition, before the rocket is ignited, the protective plate 3 is controlled to rise, and the protective plate 3 extends out of the movable groove 16 and blocks the middle position between the tail flame guiding channel 4 and the control device 6, which can resist the lateral heat jet. The surface of the protective plate 3 is coated with heat-resistant material to enhance the ability of the protective plate 3 to resist the heat of the heat jet, and avoid the control device 6 from contacting the lateral heat jet and causing heat damage, thereby increasing the service life of the equipment and reducing the cost of use; the tail flame may contain some fixed impurities, and these impurity particles are ejected with the tail flame, which may also bring some influence and potential damage to the control device 6. The protective plate 3 can prevent solid impurities from causing damage to the control device 6.

[0035] A cooling cavity 9 is symmetrically provided inside the platform body 1 and located on both sides of the tail flame guide channel 4. The movable groove 16 is arranged above the cooling cavity 9, and the movable groove 16 is communicated with the cooling cavity 9. A floating plate 13 is fixedly installed at the bottom of the protective plate 3, and the floating plate 13 is slidably arranged in the cooling cavity 9. A water pump 5 is fixedly installed on one side of the platform body 1, and a water inlet pipe 7 is fixedly installed at the water inlet end of the water pump 5. The water outlet end of the water pump 5 is connected to the cooling cavity 9 through a water delivery pipe 8. A solenoid valve 19 is fixedly installed on the other side of the platform body 1, and the water inlet end of the solenoid valve 19 is communicated with the cooling cavity 9 through a water delivery pipe 8, and a drain pipe 20 is fixedly installed at the water outlet end of the solenoid valve 19.

[0036] During operation, before ignition, the water pump 5 is turned on, the solenoid valve 19 is closed, and seawater is extracted through the water pump 5 and the water inlet pipe 7. A filter device is installed at the end of the water inlet pipe 7 to filter impurities in the seawater. The seawater enters the cooling chamber 9 through the water delivery pipe 8. The cooling chamber 9 is filled with seawater. The floating plate 13 always floats on the liquid surface, and synchronously pushes the protective plate 3 to rise along the movable groove 16, so that the protective plate 3 can block in front of the control device 6. During the ignition process, the lateral heat jet is prevented from causing damage to the control device 6;

[0037] In addition, the cooling chamber 9 is adjacent to the tail flame guide channel 4 and the protective plate 3. After the tail flame generated during ignition enters the tail flame guide channel 4, the temperature of the side wall of the tail flame guide channel 4 rises, and continuously exchanges heat with the seawater in the cooling chamber 9, thereby being able to cool the side wall of the tail flame guide channel 4 and protect the side wall. The protective plate 3 can also exchange heat with the seawater in the cooling chamber 9 through the floating plate 13, and synchronously cool and protect the protective plate 3. At the same time, the solenoid valve 19 is opened, and the seawater in the cooling chamber 9 is discharged through the solenoid valve 19 and the drain pipe 20, so that the water intake of the water pump 5 and the water discharge of the solenoid valve 19 are equal. The cooling chamber 9 is equal to the above-mentioned one. At this time, the cooling chamber 9 is always filled with seawater, and the position of the protective plate 3 remains unchanged, thereby ensuring the blocking effect on the lateral heat jet, and being able to continuously replace the seawater inside the cooling chamber 9 to ensure that the seawater temperature inside the cooling chamber 9 is relatively low, and thus always having a good cooling effect. When the rocket launch mission is completed, the seawater inside the cooling chamber 9 is drained, and under the action of gravity, the protective plate 3 descends along the movable groove 16 and is collected in the movable groove 16. Finally, the top of the protective plate 3 is flush with the deck surface, so that the protective plate 3 can be stored without occupying the deck surface space of the platform body 1, making daily use and maintenance more convenient.

[0038] An indented groove 15 is provided in the middle of the bottom of the floating plate 13, and notches 21 are provided at both ends of the bottom of the floating plate 13, respectively. The notches 21 correspond to the water inlet end of the water pump 5. When working, when water is injected into the cooling chamber 9 through the water pump 5 and the water inlet pipe 7, seawater first flows into the indented groove 15 at the bottom of the floating plate 13 through the notch 21, and then can push the floating plate 13 to move upward.

[0039] A cavity 14 is provided inside the floating plate 13, and the cross section of the cavity 14 is set to be L-shaped. The cavity 14 surrounds the side and top of the sunken groove 15. During operation, by setting the L-shaped cavity 14 inside the floating plate 13, the weight of the floating plate 13 is reduced, and the buoyancy of the floating plate 13 can be increased, so that the floating plate 13 rises together with the seawater level inside the cooling chamber 9.

[0040] An inner cavity 17 is arranged in the middle of the protective plate 3, and the bottom of the inner cavity 17 is connected to the outside of the bottom of the floating plate 13. The protective plate 3 is open on the side facing the tail flame guide channel 4, and a plurality of groups of partitions 18 are fixedly installed at intervals on the open side of the protective plate 3, and the partitions 18 are arranged to be inclined toward the inner bottom of the inner cavity 17; during operation, when the transverse heat jet generated during the ignition process contacts the side wall of the baffle, the transverse heat jet is introduced into the inner cavity 17 through the inclined partition 18 arranged on the side of the protective plate 3, so as to avoid the transverse heat jet from contacting the surface of the protective plate 3 and rebounding to generate a longitudinal heat jet, and to avoid the longitudinal heat jet from bypassing the protective plate 3 and continuing to damage the control device 6, thereby further improving the ability of the protective plate 3 to block the heat jet, and the bottom of the inner cavity 17 is connected to the cooling cavity 9, so that the heat jet in the inner cavity 17 will contact with the seawater, thereby reducing the temperature of the heat jet and further protecting the protective plate 3.

[0041] The tail flame diversion channel 4 is arranged in a herringbone shape, the top entrance of the tail flame diversion channel 4 is arranged on the deck of the platform body 1, and the outlets at both ends of the tail flame diversion channel 4 extend to the side walls of the platform body 1; when working, the tail flame generated by the rocket launch is guided to the openings on the side walls of the platform body 1 on both sides, thereby reducing the damage of the tail flame to the surface of the platform body 1.

[0042] A connecting groove 10 is provided in the middle of the cooling chambers 9 on both sides, and the connecting groove 10 passes through the lower middle of the tail flame guide channel 4; when working, the side and bottom of the tail flame guide channel 4 can exchange heat with the seawater in the cooling chamber 9.

[0043] A guide plate 11 is fixedly installed in the middle extension direction of the cooling chamber 9. The guide plate 11 is set in an isosceles triangle shape, and the size of the guide plate 11 is adapted to the inner cavity 17. During operation, since the size of the guide plate 11 is adapted to the inner cavity 17, when the protective plate 3 is received in the cooling chamber 9, the guide plate 11 can be inserted into the middle inner cavity 17 of the protective plate 3, and will not prevent the protective plate 3 from being received in the cooling chamber 9. By setting the guide plate 11, the flow direction of the seawater entering the cooling chamber 9 from the water pump 5 can be guided. After the water pump 5 pumps the seawater into the cooling chamber 9, the seawater can flow upward along the inclined side of the guide plate 11. At this time, the water flow can drive the seawater inside the cooling chamber 9 to flow, so that the seawater at a position adjacent to the tail flame guide channel 4 is discharged from the cooling chamber 9 together with the seawater at other positions, and the water at different heights in the cooling chamber 9 is led outward for replacement, so as to promote the uniformity of heat removal and avoid the problem that the top seawater cannot be updated in time.

[0044] Embodiment 2: Figure 3 to Figure 4 As shown, compared with Example 1, another implementation of the present invention is: a plurality of through holes 12 are opened in the middle of the guide plate 11, and the through holes 12 are arranged parallel to the water pipe 8; when working, the water flows along the inclined side of the guide plate 11 and can drive part of the seawater to pass through the through holes 12, so as to discharge the seawater at different positions out of the cooling chamber 9, thereby improving the uniformity of the seawater taking away the heat.

[0045] The above-mentioned front, back, left, right, top and bottom are all based on the figures in the specification. Figure 1 As a benchmark, according to the person's observation perspective, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.
