[0002] Schools in remote areas of my country can receive remote education resources through satellite antennas, conduct real-time classroom broadcasts, course playback, etc., to promote the balanced distribution of educational resources. However, since satellite antennas are usually installed on the roof of the school and are located at a high position, birds often stay on the satellite antennas. Over time, the bird droppings will inevitably adhere to the reflector of the satellite antenna. The bird droppings contain acidic substances, so the reflector is easily corroded by the bird droppings, causing the reflector to be damaged, or blocked by the bird droppings, which reduces the reflector's reflection effect on the satellite signal, thereby reducing the signal strength reflected by the reflector to the feed source, causing students to watch educational videos. The signal fluctuates. Existing means usually perform manual cleaning, but since the satellite antenna is installed on the roof, daily maintenance and cleaning operations are relatively cumbersome and inconvenient, which makes it difficult to clean the bird droppings attached to the surface of the reflector in a timely and frequent manner, causing the reflector to be damaged by the corrosion of the bird droppings. Therefore, a device is needed that can clean the bird droppings on the reflector without manually climbing to the roof. Summary of the invention

DETAILED DESCRIPTION

[0025] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments. Example 1

[0026] like Figure 2-Figure 5 As shown, a multifunctional IoT outdoor antenna includes a base 1, a reflector 2 and a feed source 3; the reflector 2 is connected to the upper side of the base 1; a reflecting surface 2001 is provided on the reflector 2; the feed source 3 is connected to the upper side of the reflector 2;

[0027] It also includes a protective plate 4, a deformation component and a rotation component; the reflector 2 is connected to the protective plate 4, and the protective plate 4 is made of polyurethane material; it is used to protect the satellite antenna without affecting the signal reception and transmission of the satellite antenna; the protective plate 4 covers the reflecting surface 2001; the protective plate 4 is provided with a contact surface 4001; the base 1 is connected to the deformation component; the base 1 is connected to the rotation component.

[0028] The deformation assembly includes a fixing rod 101 and an extrusion rod 102; the fixing rod 101 is fixed to the base 1 by bolts; the fixing rod 101 and the reflector 2 are fixed by a fixing frame; a plurality of extrusion rods 102 are fixed to the upper side of the reflector 2, and the plurality of extrusion rods 102 are arranged in a ring array.

[0029] The rotating assembly includes a power unit, a connecting frame 203, a fixing ring 204, a threaded rod 205, a connecting ring 207 and a supporting frame 208; the power unit is connected to the fixing rod 101; the supporting frame 208 is connected to the power unit; the supporting frame 208 is driven up and down by the power unit; the connecting ring 207 is rotatably connected to the supporting frame 208; the connecting frame 203 is fixedly connected to the upper side of the connecting ring 207; the fixing ring 204 is fixedly connected to the upper side of the connecting frame 203; the fixing ring 204 is fixedly connected to the protective plate 4; the threaded rod 205 is fixedly connected to the upper side of the fixing rod 101; the connecting ring 207 is screwed to the threaded rod 205.

[0030] The power unit includes a slide rail 201 and an electric slider 202 ; the slide rail 201 is fixedly connected to the inner side of the fixing rod 101 ; the electric slider 202 is slidably connected to the slide rail 201 ; the electric slider 202 is fixedly connected to the connecting frame 203 .

[0031] First, during the use of the reflector 2 and the feed source 3, the reflective surface 2001 on the reflector 2 is covered by the protective plate 4, so that the bird droppings fall on the contact surface 4001, and prevent the bird droppings from falling directly on the reflective surface 2001, causing the reflective surface 2001 to be corroded by the bird droppings, thereby reducing the reflective ability of the reflector 2 to the signal, thereby reducing the signal received by the feed source 3, and then improving the reflection effect of the reflector 2 on the signal.

[0032] Afterwards, since bird droppings will accumulate on the contact surface 4001, the reflector 2 will be blocked by the bird droppings when reflecting the signal to the feed source 3. If the blocking range is too large, the signal received by the feed source 3 will be reduced. Therefore, when the homeowner feels that the signal of the terminal equipment in the house is abnormal, the controller controls the electric slider 202 to slide upward, thereby driving the connecting ring 207 and the supporting frame 208 to move upward, and then driving the connecting frame 203, the fixing ring 204 and the protective plate 4 to move upward. At this time, under the influence of the threaded rod 205, with looking down as a reference, the connecting ring 207 will rotate clockwise along the threads on the threaded rod 205, thereby driving the protective plate 4 and the contact surface 4001 to rotate in the same manner. At the same time, under the extrusion of the extrusion rod 102, the protective plate 4 will be deformed, and after the edge of the protective plate 4 passes over the extrusion rod 102, the edge of the protective plate 4 will flip, so that the protective plate 4 changes from a shape that is concave downward and fits the reflecting surface 2001 to an upward convex shape, thereby making the protective plate 4 become as follows. Figure 4In the state shown in the figure, the bird droppings on the contact surface 4001 are broken due to the upward protrusion deformation of the protective plate 4, and the bird droppings are easy to separate from the contact surface 4001. At this time, the protective plate 4 continues to move upward. Since the reflector 2, the feed source 3 and the protective plate 4 are arranged to be tilted to the right, the bird droppings on the contact surface 4001 will move downward along the right side of the contact surface 4001 to clean the accumulated bird droppings on the contact surface 4001. However, since the left edge of the contact surface 4001 is tilted to the left, the left edge of the contact surface 4001 The adhered bird droppings will move downward along the left side of the contact surface 4001 to the reflecting surface 2001. Therefore, when the contact surface 4001 moves upward and rotates, the bird droppings on the left edge of the contact surface 4001 will be thrown out to the outside of the contact surface 4001 by the centrifugal force generated by the rotation of the contact surface 4001, preventing the bird droppings from falling along the contact surface 4001 to the reflecting surface 2001, causing the protection of the protective plate 4 to fail to protect the reflector 2 and be covered by the bird droppings, thereby improving the reflection effect of the reflector 2 on the signal. The electric slider 202 is controlled to move downward after the fixing ring 204 passes over the threaded rod 205. It is worth noting that the connecting ring 207 never separates from the thread of the threaded rod 205, thereby driving the protection plate 4, the connecting ring 207 and the fixing ring 204 to move downward. At this time, based on the view from top to bottom, the connecting ring 207 drives the threaded rod 205 to rotate counterclockwise, thereby driving the protection plate 4, the fixing ring 204 and the connecting frame 203 to rotate counterclockwise. At this time, the electric slider 202 drives the protection plate 4 to continue to rotate. The protective plate 4 continues to move downward, so that the protective plate 4 is deformed under the squeezing of the squeezing rod 102, and changes from an upward convex shape to a downward concave shape that fits the reflecting surface 2001 when passing over the squeezing rod 102, and after the connecting frame 203, the fixing ring 204 and the protective plate 4 stop moving downward, the lower side of the protective plate 4 is completely fitted with the reflecting surface 2001, realizing the reset of the connecting frame 203, the fixing ring 204 and the protective plate 4. On the other hand, when the above cleaning work is carried out on rainy days, it is easier for the bird droppings to separate from the protective plate 4 with the help of rainwater washing the protective plate 4.

[0033] The protection plate 4 is snap-fitted with the fixing ring 204 , so that the protection plate 4 can be easily disassembled and replaced, and the protection plate 4 can be regularly inspected and maintained to improve the protection effect of the reflecting surface 2001 .

[0034] The rubber cleaning plate 206 is also included; a plurality of rubber cleaning plates 206 are fixedly connected to the fixing ring 204, and the plurality of rubber cleaning plates 206 are arranged in a circular array; in the initial state, the rubber cleaning plates 206 are squeezed by the threaded rod 205 and fit with the threaded rod 205; in the process of the fixing ring 204 moving upward, the rubber cleaning plates 206 will also move upward with the movement of the fixing ring 204, and after the fixing ring 204 passes over the threaded rod 205 and continues to move upward, the rubber cleaning plates 206 will gradually return to their original state, so that the rubber cleaning plates 206 are in contact with the fixing rod 101. At this time, since the fixing ring 204 rotates driven by the connecting ring 207, the rubber cleaning plates 206 will scratch the impurities adhered to the surface of the fixing rod 101 during the upward movement, so that the impurities adhered to the surface of the fixing rod 101 will break away from the fixing rod 101 and move downward, and fall along the protective plate 4 to the outside of the protective plate 4, thereby cleaning the impurities adhered to the surface of the fixing rod 101 on the upper side of the threaded rod 205.

[0035] The two lower corners of each rubber cleaning plate 206 are arranged to be tilted toward the side away from the fixing ring 204; when the fixing ring 204 moves upward and rotates along the surface of the threaded rod 205, the rubber cleaning plate 206 will also rotate during the upward movement. Since the rubber cleaning plate 206 is in contact with the surface of the threaded rod 205, the two lower corners of the rubber cleaning plate 206 are prevented from being scratched against the threads on the threaded rod 205 during the rotation of the rubber cleaning plate 206 along the surface of the threaded rod 205, thereby preventing the rubber cleaning plate 206 from being damaged, thereby increasing the service life of the rubber cleaning plate 206.

[0036] The edge of each rubber cleaning plate 206 is arranged to be inclined toward the side away from the fixing ring 204; when the rubber cleaning plate 206 rotates and scrapes the surface of the feed source 3, the edge of the rubber cleaning plate 206 exerts a shoveling effect on the impurities on the surface of the feed source 3, thereby cleaning the bird droppings agglomerated on the surface of the feed source 3, thereby improving the cleaning effect of the rubber cleaning plate 206 on the bird droppings on the surface of the feed source 3.

[0037] The rubber cleaning plate 206 is made of polyurethane material, which facilitates the satellite antenna to send signals and prevents the signals sent by the satellite antenna from being blocked by the rubber cleaning plate 206 . Example 2

[0038] On the basis of Example 1, Figure 1 and Figure 5-Figure 7 As shown,

[0039] It also includes a servo motor 301; when the fixing rod 101 is fixedly connected to the base 1 by bolts in Example 1, the fixing rod 101 is rotatably connected to the base 1; the servo motor 301 is fixedly connected to the base 1; the output end of the servo motor 301 is fixedly connected to the fixing rod 101; a wind monitoring station is set up one hundred meters away from the base 1; and a controller is set up on the base 1.

[0040] In windy weather, when the wind monitoring station detects strong winds, it sends an electrical signal to the controller, which then controls the servo motor 301 to start, so that the fixing rod 101 rotates counterclockwise to be perpendicular to the ground, and controls the electric slider 202 to move upward, thereby driving the protective plate 4 to move upward and deform into an upward convex state. At this time, the reflector 2 and the protective plate 4 are as shown in FIG. Figure 7 The state shown on the right reduces the contact area between the reflector 2 and the strong wind, and the strong wind is directed to the upper and lower sides through the cooperation between the reflector 2 and the protective plate 4, thereby reducing the impact of the strong wind on the reflector 2, preventing the reflector 2 from being damaged by the strong wind, and improving the protection effect of the reflector 2.

[0041] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. Therefore, all equivalent changes made to the contents described in the claims of the present invention should be included in the scope of the claims of the present invention.
