Description

Technical Field

[0001] The present invention relates to the technical field of communication transmission equipment, and more specifically, to an anti-interference UAV relay communication transmission equipment. Background Art

[0002] The buoy floats on the sea surface with a relatively fixed position. It is not affected by the ship's swaying and has good communication stability. The buoy-type communication equipment usually uses solar energy or wind energy for power supply, has good endurance, and is flexibly deployable and can be placed in specific sea areas according to needs.

[0003] Currently, buoy-type relay communication equipment is deployed in the surrounding sea areas to provide communication relay for inspection and monitoring UAVs to ensure smooth communication between the UAVs and the platform control center.

[0004] In the prior art, solar panels are often used to supply power to the buoy-type relay communication equipment. However, there are often rough waves on the sea surface. When the sea waves hit the solar panels, salt will be left on their surfaces and form salt particles covering the surface of the panels after drying, which will partially block the panels and affect their photoelectric conversion efficiency. To solve this problem, in the prior art, in order to maintain the photoelectric conversion efficiency and protect the panels, part of the seawater is distilled using the cold energy of the seawater, and then the distilled water is sprayed onto the surface of the panels to wash away the salt.

[0005] However, when the cold energy of the cold water contacts the evaporated water vapor, the water vapor liquefies into distilled water, and this process is an exothermic process (the liquefaction of water vapor will release heat outward), resulting in an increase in the temperature of the cold water inside the pipeline. If the heated cold water is injected into the airbag at this time and the airbag expands to squeeze out the distilled water, part of the distilled water will evaporate, and thus the amount of distilled water sprayed onto the panels will be reduced, affecting the flushing effect. Summary of the Invention

[0006] The present invention provides an anti-interference UAV relay communication transmission equipment. The temperature of the seawater conveyed to the transfer cavity triggers the baffle to change from the stretched state to the compressed state. The baffle pulls the memory spring downward to conduct the piston cavity and the DC pipe. The DC pipe directly guides the unheated seawater to the transfer cavity for compensation and mixing, thereby reducing the temperature difference between the seawater and the distilled water conveyed to the air cushion, and thus solving the problems raised in the above background art, that is: To achieve the above object, the anti-interference UAV relay communication transmission device includes a float, a bracket, a signal transmission receiver and a filter provided on the bracket. A liquid collecting box is fixedly provided between the bottom of the bracket and the float. The liquid collecting box is communicated with a spraying device provided on the top of the solar panel. A liquid storage cavity is provided on the float outside the liquid collecting box. A liquid supply part for conveying distilled water into the liquid collecting box is communicated between the liquid storage cavity and the liquid collecting box. Cold water is passed through the liquid supply part and conveyed into the transfer cavity by a power part provided inside the float. The transfer cavity is communicated with the power part and an air cushion located in the liquid collecting box. A temperature sensing part for shunting the cold water conveyed by the power part is provided in the transfer cavity, so that the hot water in the transfer cavity is mixed and then conveyed into the air cushion to realize the flushing of the salt on the surface of the solar panel.

[0007] A drain pipe passes through the bent part of the liquid guide pipe. One end of the drain pipe is communicated with the transfer cavity, and the other end is communicated with a piston cavity in the float. When cold water is conveyed into the transfer cavity, the cold water in the drain pipe provides cold for the water vapor evaporated in the liquid guide pipe. Secondly, the temperature sensing part includes a baffle for blocking the end of the DC pipe, and a memory spring with the top fixedly provided with the baffle and the bottom fixedly provided with the inner wall of the transfer cavity. The memory spring shows a hard-phase compressed state under normal conditions and a soft-phase stretched state at low temperatures. In the above technical solution, when the seawater in the drain pipe is injected into the transfer cavity, the temperature of the seawater rises, causing the soft phase of the memory spring in the initial state to show a hard phase. The memory spring changes from the stretched state to the compressed state. During this process, the memory spring pulls the baffle away from the end of the DC pipe, enabling the DC pipe to be communicated with the piston cavity. The cold water in the piston cavity enters the transfer cavity and mixes with the heated seawater to reduce the temperature of the seawater in the transfer cavity.

[0008] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. By guiding the seawater through the drain pipe, the contact area between the water vapor and the surface of the drain pipe is maximized, improving the condensation rate of the water vapor. At the same time, the temperature of the seawater conveyed into the transfer cavity causes the baffle to change from the stretched state to the compressed state. The baffle pulls the memory spring downward to realize the conduction between the piston cavity and the DC pipe. The DC pipe directly guides the unheated seawater into the transfer cavity for compensation and mixing, thereby reducing the temperature difference between the seawater and the distilled water conveyed into the air cushion, reducing the evaporation of the distilled water, and improving the flushing effect of the salt on the surface of the solar panel.

[0009] 2. The amount of seawater conveyed from the transfer cavity into the air cushion is greater than the amount of seawater discharged from the air cushion, causing the air cushion to gradually expand and squeeze out the distilled water to wash the solar panel. At the same time, the air cushion stores the seawater briefly and returns it to the liquid storage cavity through the return pipe, realizing the recycling of the seawater so as to generate more water vapor in the liquid storage cavity.

Detailed implementation manners

[0012] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0013] Regarding the fact that when the cold energy of cold water contacts the evaporated water vapor, the water vapor liquefies into distilled water, and this process is an exothermic process, resulting in an increase in the temperature of the cold water. If the cold water with increased temperature is injected into the airbag at this time, when the airbag expands and squeezes out the distilled water, some of the distilled water will evaporate, and thus the amount of distilled water sprayed onto the battery panel will be reduced, affecting the flushing effect. The present invention provides an anti-interference UAV relay communication transmission device. See Figures 1 - 2As shown in the figure, it includes a floating buoy 100, a bracket, a signal transmission receiver 102 and a filter 103 arranged on the bracket. A liquid collecting box 110 is fixedly arranged between the bottom of the bracket and the floating buoy 100. The liquid collecting box 110 is communicated with a spraying device 101a arranged on the top of the solar panel 101. A liquid storage cavity 104 is provided on the floating buoy 100 outside the liquid collecting box 110. A liquid supply part for delivering distilled water into the liquid collecting box 110 is communicated between the liquid storage cavity 104 and the liquid collecting box 110. Cold water is transported through the liquid supply part into a transfer cavity 105 by a power part 130 arranged inside the floating buoy 100. The transfer cavity 105 is communicated with the power part 130 and an air cushion 120 arranged inside the liquid collecting box 110. A temperature sensing part 140 for diverting the cold water transported by the power part 130 is arranged inside the transfer cavity 105, so that the hot water inside the transfer cavity 105 is mixed and then transported into the air cushion 120 to reduce the evaporation of the distilled water above the air cushion 120. At the same time, the mixed cold water is sprayed from the spraying device 101a onto the surface of the solar panel 101 to realize the flushing of the salt on the surface of the solar panel 101.

[0014] By deploying buoy-type relay communication equipment in the surrounding sea areas, communication relay is provided for the drones for inspection and monitoring to ensure smooth communication between the drones and the platform control center, so as to monitor the surrounding environment.

[0015] Based on the above existing problems, the mechanism of the liquid supply part is disclosed. The liquid supply part includes a liquid collecting cover 150 which covers the liquid storage cavity 104 and is transparent. A liquid guide pipe 151 is connected between the liquid collecting cover 150 and the liquid collecting box 110. The top of the liquid guide pipe 151 is bent obliquely downward and communicated with the liquid collecting box 110 for liquefied water droplets to flow into the liquid collecting box 110. On the other hand, a drain pipe 134 penetrates through the bent part of the liquid guide pipe 151. One end of the drain pipe 134 is communicated with the transfer cavity 105, and the other end is communicated with a piston cavity 106 inside the floating buoy 100. When cold water is transported into the transfer cavity 105, the cold water in the drain pipe 134 provides cold for the water vapor evaporated in the liquid guide pipe 151.

[0016] In this way, when the sun shines on the liquid collecting cover 150, the seawater in the liquid storage cavity 104 evaporates to generate water vapor. The water vapor flows to the bent part through the liquid guide pipe 151. At the same time, the power part 130 is hit by the waves formed by the seawater, so that the power part 130 pumps the seawater at the bottom of the floating buoy 100 into the piston cavity 106 and presses it into the transfer cavity 105 through the drain pipe 134 (this process is shown in combination with the following text). At this time, the cold water in the drain pipe 134 provides cold for the evaporated water vapor to liquefy the water vapor into water droplets and flow into the liquid collecting box 110 for storage; Moreover, since the outer wall of the drain pipe 134 is close to the inner wall of the liquid guiding pipe 151 at the bent part, in this way, by the close proximity of the two pipe walls, the length of the heat conduction path can be significantly reduced, enabling the cold quantity of the cold water in the drain pipe 134 to be more efficiently transferred to the channel area through which the water vapor flows (i.e., the channel between the drain pipe 134 and the second one-way valve 152). At the same time, the contact area between the water vapor and the surface of the drain pipe 134 can be maximized, promoting more water vapor molecules to collide with the drain pipe 134 and release latent heat per unit time, thereby increasing the condensation rate of the water vapor.

[0017] It should be noted that when the cold water in the transfer cavity 105 is delivered to the air cushion 120, the air cushion 120 squeezes the distilled water stored above it out of the liquid collecting box 110, which will cause some water droplets to flow back out of the liquid guiding pipe 151. Therefore, in order to prevent the distilled water from flowing back out of the liquid guiding pipe 151, a second one-way valve 152 is provided in the liquid guiding pipe 151 at the connection between the liquid guiding pipe 151 and the liquid collecting box 110. The second one-way valve 152 is used to allow the generated distilled water to flow into the liquid collecting box 110 and restrict the distilled water from overflowing from the liquid guiding pipe 151 when the air cushion 120 squeezes the distilled water in the liquid collecting box 110.

[0018] Secondly, as shown in Figure 3 , a water inlet 107 is provided on the floating buoy 100 on one side of the liquid storage cavity 104. The water inlet 107 can guide the external seawater into the liquid storage cavity 104. A partition that can rotate unidirectionally is provided between the water inlet 107 and the liquid storage cavity 104. When the waves generated by the seawater rush into the water inlet 107, the seawater pushes the partition open clockwise. When there is no seawater injected into the water inlet 107, the water inlet 107 rotates counterclockwise to close, thereby restricting the water vapor from overflowing from the water inlet 107.

[0019] Based on the above illustrations and structures, returning to Figure 2 , the specific structure of the power unit 130 is shown. The power unit 130 includes a power plate 131 rotatably arranged outside the floating buoy 100, and a piston plate 132 rotatably arranged with the power plate 131 through a connecting rod. The piston plate 132 is movably arranged in the piston cavity 106. The piston cavity 106 is communicated with the water suction pipe 133. The first one-way valve 136 in the water suction pipe 133 is used to allow the external seawater to enter the piston cavity 106. A direct current pipe 135 is communicated between the piston cavity 106 and the transfer cavity 105. The first one-way valve 136 in the direct current pipe 135 and the drain pipe 134 is used to allow the seawater in the piston cavity 106 to enter the transfer cavity 105.

[0020] Specifically during operation, when the waves of seawater strike the power plate 131, the power plate 131 exerts pressure on the piston plate 132 through the connecting rod. The piston plate 132 presses the seawater pumped into the piston chamber 106 into the drain pipe 134. At this time, one end of the DC pipe 135 is blocked by the temperature sensing part 140, that is, the seawater can only be transported from the drain pipe 134 to the transfer chamber 105. When the impact of the seawater on the power plate 131 weakens, under the action of the gravity of the power plate 131, the piston plate 132 is pulled to move in the reverse direction through the connecting rod, and then the seawater is sucked into the piston chamber 106. In this way, seawater is supplied into the transfer chamber 105 through the reciprocating movement of the piston plate 132, so as to be later filled into the air cushion 120 to make it expand and squeeze out the distilled water.

[0021] Furthermore, as shown in Figure 4 and Figure 5 the structure of the temperature sensing part 140 is shown. The temperature sensing part 140 includes a baffle 141 for blocking the end of the DC pipe 135, and a memory spring 142 with its top fixedly arranged with the baffle 141 and its bottom fixedly arranged with the inner wall of the transfer chamber 105. The memory spring 142 shows a hard-phase compressed state under normal conditions (when cold water with rising temperature is injected into the transfer chamber 105), and shows a soft-phase stretched state at low temperature (the temperature of cold water without heating). Secondly, slide rails 143 are slidably arranged on both sides of the baffle 141, and the slide rails 143 are fixedly arranged with the inner wall of the transfer chamber 105.

[0022] Working principle: When the seawater in the drain pipe 134 is injected into the transfer chamber 105, the rising temperature of the seawater causes the memory spring 142 to change from the soft phase in the initial state to the hard phase. The memory spring 142 changes from the stretched state to the compressed state. During this process, the memory spring 142 pulls the baffle 141 away from the end of the DC pipe 135, so that the DC pipe 135 is connected to the piston chamber 106. The cold water in the piston chamber 106 enters the transfer chamber 105 to mix with the heated seawater, so as to reduce the temperature of the seawater in the transfer chamber 105. As the temperature of the seawater in the transfer chamber 105 rises, the memory spring 142 changes from compression to stretching, and the baffle 141 closes the DC pipe 135 again. In this way, as the water level in the transfer chamber 105 rises, and with the reciprocating movement of the piston plate 132, the hot water in the transfer chamber 105 is pressed into the air cushion 120 (the connection between the transfer chamber 105 and the air cushion 120 is through the liquid supply pipe 108).

[0023] That is to say, the seawater is guided through the drain pipe 134 to maximize the contact area between the water vapor and the surface of the drain pipe 134, thereby increasing the condensation rate of the water vapor. At the same time, the temperature of the seawater delivered into the transfer chamber 105 causes the baffle 141 to change from the stretched state to the compressed state. The baffle 141 pulls the memory spring 142 to move downward to connect the piston chamber 106 with the DC pipe 135. The DC pipe 135 directly guides the unheated seawater into the transfer chamber 105 for compensation and mixing, so as to reduce the temperature difference between the seawater and the distilled water delivered into the air cushion 120, reduce the evaporation of the distilled water, and improve the flushing effect on the surface salt of the solar panel 101.

[0024] Combined Figure 2 、 Figure 6 As shown, as the amount of seawater in the air cushion 120 increases, the overall weight of the float 100 increases, improving the resistance of the float 100 to external forces (such as wind waves and water currents), reducing the phenomenon of high-frequency shaking of the float 100. At the same time, the air cushion 120 expands to squeeze out the distilled water above it, and the distilled water sprays out from the spraying device 101a to wash the surface of the solar panel 101.

[0025] Also, because when the sea surface is slightly fluctuating or calm, the seawater in the liquid storage chamber 104 has evaporated completely and no seawater enters the liquid storage chamber 104. This will cause the surface of the solar panel 101 to be in a dry state for a long time. Therefore, a return pipe 121 is connected between the air cushion 120 and the liquid collecting cover 150. The diameter of the return pipe 121 is smaller than that of the liquid supply pipe 108. In this way, the seawater delivered from the transfer chamber 105 into the air cushion 120 is greater than the amount of seawater discharged from the air cushion 120, causing the air cushion 120 to gradually expand to squeeze out the distilled water to wash the solar panel 101. At the same time, the air cushion 120 stores the seawater briefly and returns it to the liquid storage chamber 104 through the return pipe 121 to realize the recycling of seawater, so as to generate more water vapor in the liquid storage chamber 104.

[0026] In summary, when the solar panel 101 is placed in seawater, when the seawater waves hit the float 100, part of the seawater will enter the liquid storage chamber 104 for storage. The seawater is used to press on the power plate 131, causing the piston plate 132 to pump the seawater into the transfer chamber 105. During this process, the cold water delivered into the transfer chamber 105 passes through the liquid guide pipe 151, and the water vapor evaporated in the liquid storage chamber 104 liquefies into water droplets after contacting the cold water with a low temperature. The water droplets flow from the liquid guide pipe 151 to the air cushion 120 in the liquid collecting box 110 for short-term storage; The temperature of the cold water flowing into the transfer chamber 105 is higher than that of the seawater not injected into the transfer chamber 105. At this time, the baffle 141 acts as a hard phase to pull the memory spring 142 downward, making the DC pipe 135 communicate with the piston chamber 106. The cold water in the piston chamber 106 is directly transported into the transfer chamber 105 to mix the cold water in the transfer chamber 105, thereby reducing the temperature of the cold water transported into the air cushion 120, reducing the evaporation of the distilled water above the air cushion 120, and improving the flushing effect on the salt.
