[0032] As Figures 1 to 10As shown in the figure, an intelligent searchlight provided by an embodiment of the present invention includes a base 200, a lamp housing 100, and a first heat dissipation mechanism. The base 200 is fixedly arranged, and the lamp housing 100 is arranged on the base 200 and rotatably connected to the base 200. A sealed cavity is provided inside the lamp housing 100. The first heat dissipation mechanism includes a fixed shaft 101, a power component, and a heat conduction component. The fixed shaft 101 is rotatably arranged in the lamp housing 100 and is located outside the cavity. The power component is used to drive the fixed shaft 101 to rotate unidirectionally. The power component is a first motor 102, and the output shaft of the first motor 102 is connected to the fixed shaft 101. The heat conduction component includes a fan plate 103 and a plurality of telescopic rods. The fan plate 103 is fixedly installed on the lamp housing 100, and the fan plate 103 is fan-shaped. The peripheral surface of the fan plate 103 includes an arc surface and a flat surface. The arc surface of the fan plate 103 penetrates the lamp housing 100 and extends into the cavity, and the flat surface of the fan plate 103 is located outside the lamp housing 100. A groove 104 is provided on the flat surface of the fan plate 103. The fan plate 103 is perpendicular to the fixed shaft 101, and the fixed shaft 101 penetrates the fan plate 103 along its own axial direction. The projection of the groove 104 in the axial direction of the fixed shaft 101 is fan-shaped. There is a spacing between the axis of the fixed shaft 101 and the axis of the groove 104. One end of a plurality of telescopic rods is fixedly installed on the fixed shaft 101 and is circumferentially distributed around the fixed shaft 101.

[0033] The telescopic rod can rotate and slide into the groove 104 and is slidably connected to the fan plate 103. A plurality of telescopic rods can be located in the groove 104 at the same time. After each telescopic rod enters the groove 104, it gradually elongates and abuts against the fan plate 103. There is a chamber with variable pressure between two adjacent telescopic rods located in the groove 104. A convex platform is provided on the fixed shaft 101. The convex platform is rotatably arranged in the groove 104. The telescopic rod is fixedly connected to the convex platform. The chamber is jointly surrounded by two adjacent telescopic rods, the convex platform, and the fan plate 103 in the groove 104.

[0034] Providing the fan plate 103 with the groove 104 can increase the contact area between the cavity and the outside world and improve the heat dissipation effect of the cavity. Through the cooperative setting of the telescopic rod and the groove 104, the rotation of the telescopic rod can increase the flow rate of the gas in the groove 104. At the same time, the telescopic rod can scrape the impurities in the groove 104, further improving the heat dissipation effect of the cavity. When the telescopic rod enters the groove 104, as the telescopic rod continuously elongates, the volume of the chamber between two adjacent telescopic rods in the groove 104 will increase, and the pressure will gradually decrease, thereby reducing the temperature in the chamber and improving the heat dissipation efficiency of the cavity again.

[0035] In this embodiment, the heat conduction component further includes an arc plate 105. The two ends of the arc plate 105 are respectively connected to the fan plates 103, and the arc plate 105 is coaxial with the groove 104. After the telescopic rod rotates out of the groove 104, it will abut against the arc plate 105, and when the telescopic rod enters the groove 104 again, it will be relatively smooth under the guidance of the arc plate 105. A protective cover 116 is provided on the lamp housing 100, and the first heat dissipation mechanism is located inside the protective cover 116. The protective cover 116 is a porous structure and does not hinder the exchange of gas inside the protective cover 116 with the outside world.

[0036] In this embodiment, the rotation direction of the fixed shaft 101 is set as the first direction. As Figure 3 shown, the first direction is the clockwise direction, and the fixed shaft 101 drives a plurality of telescopic rods to rotate clockwise. An air vent part is formed on the rear side surface of the telescopic rod. The air vent part penetrates the telescopic rod along the first direction, so that two adjacent chambers inside the groove 104 communicate with the outside. The air vent part includes a first through groove 108 and air holes 109, and the first through groove 108 and the air holes 109 penetrate the telescopic rod along the first direction. After the telescopic rod slides into the groove 104, since the pressure in the chamber between two adjacent telescopic rods inside the groove 104 will gradually decrease, the pressures of the multiple chambers located inside the groove 104 are not equal, and the chamber with a smaller pressure will extract the gas in the adjacent chamber with a larger pressure through the first through groove 108 and the air holes 109. The flow rate of the gas passing through the first through groove 108 and the air holes 109 increases, and the temperature decreases, which will reduce the temperature of the fan plate 103 when acting on the fan plate 103.

[0037] The first through groove 108 and the air holes 109 are relatively small, and a relatively large flow rate can be generated when the gas passes through the first through groove 108 and the air holes 109. The greater the speed of the gas, the better the cooling effect on the fan plate 103.

[0038] In this embodiment, each telescopic rod is hollow inside, and the ventilation part penetrates through the inside of the telescopic rod. A sponge 110 is provided inside the telescopic rod. Each telescopic rod includes a fixed part 106 and a movable part 107. One end of the fixed part 106 is fixedly installed on the fixed shaft 101, and a chute 111 is opened at the other end of the fixed part 106. One end of the movable part 107 is slidably arranged in the chute 111, and the other end of the movable part 107 abuts against the fan plate 103. An accommodation groove 112 is opened at one end of the movable part 107 located in the fixed part 106. The accommodation groove 112 communicates with the chute 111, and the accommodation groove 112 communicates with the first through groove 108. The sponge 110 is located in the accommodation groove 112 and the chute 111, and both ends of the sponge 110 are respectively connected to the fixed plate and the movable part 107. The first through groove 108 is arranged on the movable part 107 and penetrates through the movable part 107 along the first direction. The air holes 109 are arranged on the fixed part 106 and penetrate through the fixed part 106 along the first direction. When the telescopic rod contracts, the first through groove 108 communicates with the air holes 109, and the gas will pass through the sponge 110 when passing through the first through groove 108 and the air holes 109. The sponge 110 is flexible. When the movable part 107 approaches the fixed part 106, the sponge 110 is bent in the chute 111. When the movable part 107 moves away from the fixed part 106, the sponge 110 is stretched. Steps are provided on the surface of the groove 104, and the fixed part 106 and the movable part 107 are in contact with the fan plate 103 through the steps respectively. A spring is provided between the fixed part 106 and the sliding part.

[0039] A second through groove 113 communicating with the inside of the telescopic rod is opened on the telescopic rod. The second through groove 113 penetrates through the telescopic rod along the axial direction of the fixed column. An included angle is provided between the axial direction of the fixed shaft 101 and the horizontal direction; when the telescopic rod is located in the groove 104, the fan plate 103 blocks the second through groove 113, and the second through groove 113 is closed. The gas in the chamber can only enter and exit through the first through groove 108 and the air holes 109. When the telescopic rod is outside the groove 104 and it is raining, the rainwater will enter the chute 111 through the second through groove 113 and then be absorbed by the sponge 110. When the telescopic rod enters the groove 104 with the water-absorbed sponge 110, the gas in the chamber with a higher pressure in the groove 104 will enter the adjacent chamber with a lower pressure through the first through groove 108 and the air holes 109. The flowing gas will pass through the sponge 110 and then take away the moisture in the sponge 110. The greater the pressure difference, the faster the gas flow rate, and the more dispersed the water is. The dispersed water can evaporate and absorb heat better.

[0040] In another embodiment, a partition is provided on each telescopic rod. The partition divides the second through groove 113 into two parts in the first direction. When the telescopic rod slides into the groove 104, the two parts of the second through groove 113 are isolated from each other. Sponges 110 are provided in both parts of the second through groove 113. The partition includes a first plate 114 and a second plate 115. The first plate 114 is fixedly installed on the movable part 107, and the second plate 115 is fixedly installed on the fixed part 106. The first plate 114 and the second plate 115 are slidably connected. When the telescopic rod slides into the groove 104, when the first plate 114 and the second plate 115 divide the second through groove 113 into two, they also divide the accommodating groove 112 and the sliding groove 111 into two in the first direction. The chamber in the groove 104 is a closed chamber at this time. As the fixed shaft 101 rotates, the volume of the chamber becomes larger and the pressure becomes smaller, and the moisture in the sponge 110 can volatilize faster.

[0041] In this embodiment, there are multiple heat conduction components, and the multiple heat conduction components are arranged along the axial direction of the fixed shaft 101. The multiple fan plates 103 can further increase the contact area between the cavity and the outside world and improve the heat dissipation efficiency.

[0042] In this embodiment, the intelligent searchlight further includes a second heat dissipation mechanism and multiple lamp beads 120. The second heat dissipation mechanism includes a rotating cylinder 121 and a driving component. There are multiple rotating cylinders 121, and the multiple rotating cylinders 121 are rotatably arranged on the lamp housing 100 around their own axes, and the multiple rotating cylinders 121 are distributed around the center of the lamp housing 100. One end of the rotating cylinder 121 is located in the cavity, and there is an included angle between the axis of rotation of the rotating cylinder 121 and the axis of the fixed shaft 101; the multiple lamp beads 120 are divided into multiple groups, and the number of lamp beads 120 in each group is multiple. Each group of lamp beads 120 is arranged in a rotating cylinder 121, and the multiple lamp beads 120 in each rotating cylinder 121 are arranged along the circumferential direction of the rotating cylinder 121. The driving component is used to drive the multiple rotating cylinders 121 to rotate around their own axes.

[0043] The irradiation direction of the lamp bead 120 is consistent with the axial direction of the rotating cylinder 121. The rotating rotating cylinder 121 changes the position of the lamp bead 120 column on the lamp housing 100, which will enable each lamp bead 120 to dissipate heat better when it rotates to a position close to the edge of the lamp housing 100. The driving component includes a second motor 122 and a gear 123. The second motor 122 is fixedly installed in the cavity, the gear 123 is fixedly installed on the output shaft of the second motor 122, the extending direction of the axis of the gear 123 is consistent with the extending direction of the axis of the rotating cylinder 121, and teeth are provided on the circumferential surface of each rotating cylinder 121. The gear 123 meshes with the rotating cylinder 121 through the teeth, and the multiple rotating cylinders 121 are arranged along the circumferential direction of the gear 123. The rotation of the gear 123 can drive the multiple rotating cylinders 121 to rotate simultaneously.

[0044] In this embodiment, a circuit board 124 is provided in the cavity. The lamp beads 120 and the circuit board 124 are connected by wires. The wires between the lamp beads 120 and the circuit board 124 have a certain length. After the lamp beads 120 rotate with the rotating cylinder 121 and the wires are wound several times, the second motor 122 drives the rotating cylinder 121 to rotate back and forth to prevent the wires from breaking. One end of each rotating cylinder 121 located in the cavity is rotatably arranged on the circuit board 124. The second heat dissipation mechanism further includes a fan blade 125. The fan blade 125 is rotatably arranged in the cavity and is used to promote the gas flow in the cavity. The fan blade 125 includes a plurality of blades. The plurality of blades are all arranged on the output shaft of the second motor 122, and the plurality of blades are evenly arranged in the circumferential direction around the output shaft of the second motor 122. The rotation of the second motor 122 can drive the plurality of blades to rotate.

[0045] In this embodiment, ventilation grooves 126 are provided on the circumferential surface of the circuit board 124. Through holes 127 are provided on the circuit board 124. There is a distance between the through holes 127 and the ventilation grooves 126. The fan blade 125 is located on the side of the circuit board 124 away from the first heat dissipation mechanism in the axial direction of the rotating cylinder 121, and the through holes 127 are within the rotation range of the fan blade 125. When the second motor 122 drives the fan blade 125 to rotate, the fan blade 125 transports the heat between the rotating cylinder 121 and the circuit board 124 to the vicinity of the fan plate 103 through the through holes 127, and draws the cooled gas near the fan plate 103 to the vicinity of the rotating cylinder 121 through the ventilation grooves 126 to cool the lamp beads 120.

[0046] In this embodiment, a temperature sensor is provided in the cavity. A control panel is provided on the base 200. The control panel adjusts the rotation speed of the fixed shaft 101 and the rotation speed of the drive assembly driving the rotating cylinder 121 to rotate according to the temperature detected by the temperature sensor. The rotation speeds of the fixed shaft 101 and the rotating cylinder 121 are positively correlated with the temperature detected by the temperature sensor. The higher the temperature inside the lamp housing 100, the faster the fixed shaft 101 and the gear 123 rotate.

[0047] The working principle of an intelligent searchlight provided by the above embodiment is as follows:

[0048] After the lamp beads 120 work for a period of time, the temperature of the lamp housing 100 rises. The temperature sensor transmits the detected temperature to the control panel, and the control panel controls the start of the first motor 102 and the second motor 122.

[0049] When the first motor 102 rotates, it drives the fixed shaft 101 to rotate. The fixed shaft 101 drives the multiple telescopic rods in each heat conduction component to rotate. The movable part 107 of the telescopic rod abuts against the arc plate 105 under the action of the spring. The movable part 107 of the telescopic rod contacts the fan plate 103 under the guidance of the arc plate 105. The telescopic rod slides into the groove 104 of the fan plate 103. At this time, the length of the telescopic rod in the groove 104 is the shortest. When two adjacent telescopic rods form a chamber in the groove 104 of the fan plate 103, with the rotation of the fixed shaft 101 and the push of the spring, the movable part 107 of the telescopic rod slides away from the fixed shaft 101 relative to the fixed part 106, the volume of the chamber increases, a negative pressure will be formed in the chamber, and the gas outside the chamber will enter the chamber through the first through groove 108 and the air hole 109 on the fixed part 106. The gas flow will blow the fan plate 103 in the chamber, so that the temperature of the chamber is further reduced; if the sponge 110 adsorbs water at this time, the flowing gas will blow the water into the chamber, and the water entering the chamber will form an approximate water mist state under the gas flow, which can better dissipate the heat of the fan plate 103 in the chamber. The telescopic rod continues to rotate until it slides out of the groove 104 of the fan plate 103. After the telescopic rod slides out of the groove 104, the movable part 107 of the telescopic rod abuts against the arc plate 105 again.

[0050] When the second motor 122 rotates, the second motor 122 drives the gear 123 and the fan blade 125 to rotate. The rotation of the gear 123 drives the multiple rotating cylinders 121 to rotate synchronously through meshing with the multiple rotating cylinders 121. The rotation of the rotating cylinder 121 drives the corresponding group of lamp beads 120 to rotate, changing the distance between the lamp beads 120 and the edge of the lamp housing 100, so that the heat dissipation of the multiple lamp beads 120 in each group is more uniform; at the same time, the rotation of the second motor 122 drives the fan blade 125 to rotate, and the rotation of the fan blade 125 drives the gas flow in the cavity, accelerating the heat transfer in the cavity. After the second motor 122 rotates forward for a certain period of time, it starts to rotate in the reverse direction, so that the wire between the lamp beads 120 and the circuit board 124 will not be wound too tightly and break.

[0051] In another embodiment, after the telescopic rod enters the groove 104, the movable part 107 of the telescopic rod drives the first plate 114 to slide relative to the second plate 115. Two adjacent telescopic rods form a sealed chamber in the groove 104. When the volume of the chamber increases, the pressure in the chamber will decrease sharply, thereby reducing the temperature in the chamber. If there is water in the sponge 110, in an environment with a lower pressure, the evaporation temperature of the water will also decrease, which can promote cooling.

[0052] When the temperature in the cavity is too high through the temperature sensor, control the first motor 102 to increase the rotation speed of the fixed shaft 101 to increase the heat dissipation speed of the fan plate 103, and at the same time control the second motor 122 to increase the rotation speeds of the rotating cylinder 121 and the fan blade 125 to accelerate the gas circulation in the cavity.

[0053] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0054] The above-described embodiments merely represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
