DETAILED DESCRIPTION

[0042] The following is a detailed description of an embodiment of the present invention. This embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation method and a specific operation process are given. However, the protection scope of the present invention is not limited to the following embodiments. In the description of the present invention, words indicating directions or positional relationships such as "front", "rear", "left", and "right" are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0043] The embodiment discloses a communication device anti-interference device based on a self-organizing network, such as Figure 1-Figure 14 As shown, it includes an anti-interference mechanism 1, wherein the anti-interference mechanism 1 is installed on the antenna 2, and is specifically configured as follows: the anti-interference mechanism 1 scrapes away impurities such as dust on the reflecting surface of the antenna 2, thereby preventing the dust on the reflecting surface of the antenna 2 from affecting the strength and quality of the signal received by the antenna 2;

[0044] It should be noted that if Figure 1 and Figure 2 As shown, the antenna 2 is configured to have a parabolic reflecting surface. Specifically, the antenna 2 includes a reflecting portion 201, a high-frequency head component 202 and a base frame 203, wherein the reflecting portion 201 is configured as a metal parabola, and the high-frequency head and other components are arranged at the focus of the reflecting portion 201, and the satellite signal is reflected to the feed source and the high-frequency head located at the focus through the reflecting portion 201, and the base frame 203 is arranged on the back side of the reflecting portion 201 to support and fix the reflecting portion 201.

[0045] like Figure 1 and Figure 3 As shown, the base frame 203 includes a fixing ring 231, a fixing cylinder 232, a connecting frame 233 and a base 234, wherein, in this embodiment, the reflecting portion 201 is formed by splicing a plurality of sector plates 211, and a through hole 212 is formed at the center of the plurality of sector plates 211, and a fixing ring 231 is provided on the back of the reflecting portion 201, each sector plate 211 is fixedly connected to the fixing ring 231 by a fastener, and a fixing cylinder 232 is provided at the center of the fixing ring 231, and the fixing ring 231 and the fixing cylinder 232 are fixedly connected by a connecting frame 233, and a base 234 is provided at the other end of the fixing cylinder 232, and the top end of the base 234 is connected to one end of the fixing cylinder 232 by a fastener;

[0046] In actual work, due to the shape characteristics of the reflective part 201 and because the antenna 2 is generally arranged outdoors, dust and other impurities in the air may fall on the reflective surface of the reflective part 201, and the dust and other impurities may block and cover the reflective part 201, thereby affecting the intensity and quality of the signal received by the antenna 2. Therefore, in this embodiment, a corresponding anti-interference mechanism 1 is provided for dust and impurities to reduce the interference of dust factors on the signal of the antenna 2;

[0047] Specifically, Figure 1-Figure 5 As shown, the anti-interference mechanism 1 includes a scraper 101 and a driving assembly 102, wherein the scraper 101 is located on the reflecting surface of the reflecting portion 201 when in use and is driven by the driving assembly 102, so that the scraper 101 rotates around the center of the reflecting portion 201, and dust and other impurities on the surface of the reflecting portion 201 are scraped off by the scraper 101, thereby preventing dust from affecting the strength and quality of the signal received by the antenna 2;

[0048] Through the above configuration, the scraper 101 can be controlled by the driving component 102 to move to remove dust. In actual work, the scraper 101 is on the reflecting surface of the reflecting part 201, and the scraper 101 will block part of the reflecting part 201, which will affect the signal reception under normal conditions. Therefore, in this embodiment, if Figure 1-Figure 6 As shown, a fan-shaped groove 3 is provided on the reflective portion 201, and the fan-shaped groove 3 passes through the upper and lower end surfaces of the reflective portion 201 plate, and a movable reflective plate 4 is inserted into the interior of the fan-shaped groove 3, and the movable reflective plate 4 extends from the through hole 212 at the center of the circle toward the outer circumference, and the movable reflective plate 4 and the reflective portion 201 are an integral parabola. In other words, the reflective portion 201 is spliced ​​by a plurality of fan-shaped plates, and the movable reflective plate 4 is one of the fan-shaped plates 211, and this fan-shaped plate 211 is a plurality of equally divided fan-shaped plates of the entire reflective portion 201. One, and the scraper 101 is arranged on the back of the movable reflector 4, so when working, the movable reflector 4 can be raised by the driving component 102, and the scraper 101 on the back of the movable reflector 4 is placed above the reflective surface of the reflective portion 201, and then the movable reflector 4 is controlled to rotate, so as to perform dust scraping on the reflective portion 201, and the dust and other impurities scraped by the scraper 101 can fall as the scraper 101 moves to the fan-shaped groove 3, so as to remove the dust and other impurities on the reflective portion 201;

[0049] Through the above arrangement, when the antenna 2 works normally under normal conditions, the movable reflecting plate 4 can be inserted into the fan-shaped slot 3, so that the reflecting portion 201 forms a complete circular parabola, and the scraper 101 can be located on the back of the reflecting portion 201, thereby preventing the scraper 101 from blocking the reflecting portion 201 and affecting the signal reception.

[0050] In actual operation of the scraper 101, when the scraper 101 moves along the reflective portion 201 for one circle and scrapes away dust and other impurities on the reflective surface, a large amount of dust and other impurities may adhere to the scraper 101, thereby affecting the scraper 101's dust removal operation on the reflective portion 201 in subsequent operations.

[0051] Therefore, in this embodiment, if Figure 5 As shown, by arranging a scraper plate 5 inside the fan-shaped groove 3, the scraper plate 101 is cleaned by the scraper plate 5, thereby preventing impurities from adhering to the scraper plate 101 and affecting the subsequent scraping of the reflective portion 201;

[0052] Specifically, Figure 5-Figure 7 As shown, the thickness of the movable reflector 4 is set to be smaller than the height of the fan-shaped groove 3, and a shovel plate 5 is provided on one side of the forward direction of the rotational movement of the scraper 101. In other words, the dust scraping surface of the scraper 101 is set to the shovel plate 5, and the shovel plate 5 is located inside the fan-shaped groove 3 and is fixedly connected to the inner wall of the fan-shaped groove 3. The shovel plate 5 and the facing side of the scraper 101 are in contact with each other, and then each time the scraper 101 enters the fan-shaped groove 3, the scraper 101 contacts one end of the shovel plate 5 and the impurities on the surface are scraped once through the shovel plate 5.

[0053] It should be noted that the upper end surface of the shovel plate 5 can be set as an inclined surface, and specifically inclined toward the inner wall direction of the fan-shaped groove 3;

[0054] In addition, considering that dust and other impurities are scraped off by a scraper 101 moving one circle on the reflecting part 201, the long-distance movement of the scraper 101 will reduce the scraping frequency of the scraper 101. Therefore, the number of fan-shaped grooves 3 is set to at least two. In the present embodiment, the number of fan-shaped grooves 3 is specifically set to three, and the three fan-shaped grooves 3 are arranged in a circular array with the center of the reflecting part 201 as the center. Correspondingly, movable reflecting plates 4 are inserted into the interiors of the three fan-shaped grooves 3, and scrapers 101 are arranged on the backs of the three movable reflecting plates 4. There are three scrapers 101, so that when the scraper 101 is driven by the driving component 102 to scrape the dust, the three scrapers 101 and the three fan-shaped grooves 3 are arranged, so that each scraper 101 can enter the fan-shaped groove 3 after a short-distance scraping and perform a cleaning through the shovel plate 5, and the arrangement of the three scrapers 101 can scrape at multiple frequencies to improve the dust scraping effect.

[0055] Through the above arrangement, after each scraper 101 moves at an angle to scrape dust from a sector-shaped section of the reflective portion 201, the scraper 101 will enter the next sector-shaped groove 3 in the movement route, and at the same time, the scraper 101 will be cleaned once by the shovel plate 5 inside the sector groove 3. After the cleaning is completed, the scraper 101 rises again to scrape dust from the next sector-shaped section, and dust and other impurities are discharged from the sector groove 3. Therefore, the scraper 101 can automatically clean the scraper 101 during the process of scraping dust from the reflective portion 201, thereby preventing a large number of impurities from sticking to the scraper 101 and affecting the dust removal work of the reflective portion 201.

[0056] like Figure 1 , Figure 3 , Figure 4 , Fig. 9 and Fig.10 As shown, the driving assembly 102 includes a driving part 121 and a lifting part 122, wherein the driving part 121 is installed at one end inside the fixed cylinder 232, and is powered by the driving part 121, and the lifting part 122 is also arranged inside the fixed cylinder 232, and one end of the lifting part 122 extends to the through hole 212, and the three movable reflecting plates 4 and the centripetal end of the scraper 101 are connected to the end of the lifting part 122 located inside the through hole 212, therefore, the lifting and lowering of the three scrapers 101 can be controlled by the lifting part 122, so that the three scrapers 101 can be lifted and moved onto the reflecting surface, or lowered and moved into the fan-shaped groove 3, and the lifting part 122 is also arranged to have a rotating function, so that after the lifting part 122 is lifted, the three scrapers 101 can be rotated at an angle after moving onto the reflecting surface of the reflecting part 201, thereby removing dust from a fan-shaped interval;

[0057] More specifically, the driving part 121 is configured as a reciprocating driving member, such as Fig. 9 As shown, the driving part 121 includes a driving motor 1211, an outer tube 1212, an inner tube 1213, an inner shaft 1214, a reciprocating shaft 1215, a surrounding groove 1216 and a plug pin 1217, wherein the driving motor 1211 is fixedly installed at one end of the fixed cylinder 232, and the outer tube 1212 is fixedly arranged at one end of the fixed cylinder 232, and the inner shaft 1214 is rotatably arranged at one end of the outer tube 1212, and the two ends of the inner shaft 1214 extend to the outer tube 1213 and the inner shaft 1214 respectively. The inner tube 1212 is provided with an inner shaft 1214 and an outer tube 1212, and one end of the inner shaft 1214 located outside the outer tube 1212 is drivingly connected to the output end of the driving motor 1211, and the inner tube 1213 is slidably sleeved on the outer end of the inner shaft 1214 located inside the outer tube 1212, and the other end of the inner tube 1213 is fixedly provided with a reciprocating shaft 1215, and the other end of the reciprocating shaft 1215 slides through the end wall of one end of the outer tube 1212 and extends to the side facing the lifting part 122;

[0058] The surrounding groove 1216 surrounds the outer circumferential wall of the inner shaft 1214 and is configured to be formed by two V-shaped grooves connected to each other, and the V-shaped groove is configured to extend from one end of the inner shaft 1214 to the other end to the midpoint of the semi-circular wall and then to the starting end to the other side of the semi-circular wall, and the connection between the two V-shaped grooves is smoothly transitioned and forms a closed-loop annular groove 701 on the plane, and the insides of the two V-shaped grooves are movably plugged with plug pins 1217, and the two plug pins 1217 are respectively fixedly connected to the inner wall of the inner tube 1213. Through the above configuration, when the driving motor 1211 is started, the inner shaft 1214 is driven to rotate, and the rotation of the inner shaft 1214 is coordinated with the surrounding groove 1216 and the plug pin 1217, so that the inner tube 1213 drives the reciprocating shaft 1215 to reciprocate linearly, and the reciprocating shaft 1215 is connected to the lifting part 122, and the lifting part 122 is driven to rise and fall through the reciprocating shaft 1215;

[0059] like Figure 4 and Fig.10 As shown, the lifting part 122 includes a lifting sleeve 1221, an inner cylinder 1222, a lifting shaft 1223, a top plate 1224, an elastic member 1225, a spiral groove 1226, a movable plate 1227 and a plug-in column 1228, wherein the lifting sleeve 1221 is slidably plugged into the other end of the fixed cylinder 232, and the other end of the lifting sleeve 1221 extends to the through hole 212, and the inner cylinder 1222 is concentrically arranged inside the lifting sleeve 1221, and the inner cylinder 1222 and the lifting sleeve 1221 are rotatably connected through a bearing, and the lifting shaft 1223 is arranged inside the inner cylinder 1222, and one end of the lifting shaft 1223 slides through one end wall of the inner cylinder 1222 and extends to be fixedly connected to the reciprocating shaft 1215, and the other end of the lifting shaft 1223 is inside the inner cylinder 1222 and fixed. A top plate 1224 is fixedly connected, and the top plate 1224 is movably inserted in the inner tube 1222. An elastic member 1225 is provided on the side of the top plate 1224 facing the reciprocating shaft 1215, and the other end of the elastic member 1225 contacts the inner wall of the inner tube 1222, and the top plate 1224 is rebounded toward the direction of the reflecting portion 201 by the elastic member 1225. Therefore, when the reciprocating shaft 1215 rises, the reciprocating shaft 1215 will drive the lifting shaft 1223 to rise, and the lifting shaft 1223 will push the top plate 1224 and push the inner tube 1222 upward through the top plate 1224, and the inner tube 1222 will drive the lifting sleeve 1221 to move upward, so that the lifting sleeve 1221 rises, and the scraper 101 is connected to one end of the lifting sleeve 1221 located at the through hole 212, so that the scraper 101 can rise;

[0060] In order to make the scraper 101 rotate and remove dust after it rises, a movable disk 1227 is connected to a fixed sleeve on a section of the lifting shaft 1223 located outside the inner cylinder 1222. Correspondingly, a spiral groove 1226 is provided on the inner wall of the lifting sleeve 1221 and in the movable interval of the movable disk 1227. The spiral groove 1226 extends from a point on the inner wall of the lifting sleeve 1221 along the axial direction of the lifting sleeve 1221 and extends along the circumferential direction of the lifting sleeve 1221 at the same time. The outer circumference of the movable disk 1227 is The outer wall is fixedly provided with a plug-in column 1228, and the other end of the plug-in column 1228 is movably plugged into the inside of the spiral groove 1226. Therefore, when the lifting shaft 1223 moves linearly, it can drive the moving disk 1227 to move linearly, and the linear movement of the moving disk 1227 can make the lifting sleeve 1221 rotate at an angle through the cooperation of the spiral groove 1226 and the plug-in column 1228, thereby making the scraper 101 rotate to remove dust from the reflective surface of the reflective part 201;

[0061] In addition, if Figure 1 , Figure 4 , Fig.11 — Fig.14 As shown, a positioning sleeve 6 is fixedly provided on the back of the reflective portion 201, and the positioning sleeve 6 is concentrically provided with the through hole 212, and the lifting sleeve 1221 is slidably plugged into the inner hole of the positioning sleeve 6, and a positioning component 7 is provided between the lifting sleeve 1221 and the positioning sleeve 6, and the lifting sleeve 1221 is locked in the longitudinal position by the positioning component 7;

[0062] Specifically, the positioning assembly 7 includes an annular groove 701 and an elastic latch 702, wherein the annular groove 701 is provided on the outer circumferential outer wall of the lifting sleeve 1221, and an elastic latch 702 is provided at one end of the inner circle of the positioning sleeve 6, and the elastic latch 702 is specifically located at one end of the interior of the positioning sleeve 6 close to the direction of the reflecting portion 201, and the elastic latch 702 is configured to be plugged and matched with the annular groove 701. It should be noted that when the lifting sleeve 1221 is not rising, the elastic latch 702 and the annular groove 701 are staggered in the linear direction and are respectively located at the two ends of the positioning sleeve 6. Only when the lifting sleeve 1221 rises, the annular groove 701 and the elastic latch 702 will overlap in the linear direction, and the elastic latch 702 will be plugged into the annular groove 701 to lock the lifting sleeve 1221 in the linear direction.

[0063] More specifically, the elastic latch 702 includes a latch body 722 and a latch groove 721, wherein the latch groove 721 is provided on the inner wall of the positioning sleeve 6, and the latch body 722 is movably plugged into the inside of the latch groove 721 and elastically controlled by the spring 10, and one end of the latch body 722 is connected to a connecting rope 9, and the other end of the connecting rope 9 extends to the outside of the positioning sleeve 6 through the hole, and accordingly, a connecting rod 12 is fixedly connected to the outer wall of the lifting shaft 1223, and a yielding groove 11 is provided on the outer wall of the fixing cylinder 232, and one end of the connecting rod 12 extends to the outside of the fixing cylinder 232 through the yielding groove 11, and the other end of the connecting rope 9 is fixedly connected to one end of the connecting rod 12 located outside the fixing cylinder 232, and the linear motion of the lifting shaft 1223 drives the connecting rope 9 to pull the latch body 722, thereby controlling the contraction of the latch body 722;

[0064] Furthermore, when the lifting shaft 1223 descends to the lower limit position, that is, when the reciprocating drive member controls the reciprocating shaft 1215 to move to the lower limit position, the connecting rope 9 is tightened and the latch body 722 is contracted, so that the latch body 722 is completely contracted into the latch groove 721, and then the latch body 722 is separated from the annular groove 701 to unlock the linear lock of the lifting sleeve 1221. Correspondingly, when the lifting sleeve 1221 rises to the upper limit position, that is, the reciprocating drive member controls the reciprocating shaft 1215 to rise to the upper limit position, in order to better limit the lifting and lowering of the lifting sleeve 1221, a limiting ring 8 is fixedly sleeved on the outer wall of the lifting sleeve 1221, and the limiting The ring 8 can contact the open end wall of one end of the fixed cylinder 232, thereby limiting the rise of the lifting sleeve 1221. When the lifting sleeve 1221 rises to the upper limit position, the scraper 101 at one end of the lifting sleeve 1221 moves to the reflective surface of the reflective portion 201, and the lower end surface of the scraper 101 fits the reflective surface, and then the scraper 101 can remove dust from the reflective surface during the rotation movement. In addition, when the lifting sleeve 1221 moves to the upper limit position, the annular groove 701 overlaps with the latch body 722, and the latch body 722 is inserted into the annular groove 701 through the action of the spring 10 to linearly lock the lifting sleeve 1221.

[0065] Therefore, through the above arrangement, when the reflecting surface of the reflecting part 201 needs to be dusted, the driving motor 1211 is first started, and the driving motor 1211 makes the reciprocating shaft 1215 rise and fall through the cooperation of the inner shaft 1214 and the inner tube 1213. When the reciprocating shaft 1215 rises, the reciprocating shaft 1215 drives the lifting shaft 1223 to rise, and the lifting shaft 1223 drives the top plate 1224 to rise. Since the top plate 1224 is located at one end of the inner tube 1222 at this time, the top plate 1224 will directly push up the inner tube 1222, and move the lifting sleeve 1221 upward through the inner tube 1222. After the lifting sleeve 1221 moves up, when the lifting sleeve 1221 moves to the upper limit position, the scraper 101 will rise and be above the reflecting surface, and at the same time, the annular groove 701 overlaps with the latch body 722, and the latch body 722 rebounds under the control of the spring 10, so that the latch body 722 is inserted into the annular groove 701, thereby linearly locking the lifting sleeve 1221, and then the reciprocating shaft 1215 descends, and the reciprocating shaft 1215 will drive the lifting shaft 1223 to descend, and the descent of the lifting shaft 1223 will cause the top plate 1224 to descend, and because the lifting sleeve 1221 is locked, the lifting sleeve 1221 cannot be directly The lifting sleeve 1221 and the inner cylinder 1222 will keep their height positions fixed, the top plate 1224 will descend alone inside the inner cylinder 1222 and compress the elastic member 1225, and while the lifting shaft 1223 descends, it will drive the movable plate 1227 to move longitudinally, and the movable plate 1227 will cooperate with the plug-in column 1228 and the spiral groove 1226 to make the lifting sleeve 1221 rotate, and the rotation of the lifting sleeve 1221 will drive the scraper 101 to rotate, so that the scraper 101 will rotate at an angle above the reflective surface to remove dust from the reflective surface, and the dust and other impurities are pushed to the fan-shaped groove 3 is discharged, and by configuring the spiral groove 1226, when the lifting shaft 1223 moves to the lower limit, the lifting cylinder drives the scraper 101 to rotate and move to the next fan-shaped groove 3, and then the connecting rope 9 is tightened and the latch body 722 is contracted, so that the latch body 722 is completely contracted into the latch groove 721, and then the latch body 722 is separated from the annular groove 701 to unlock the linear locking of the lifting sleeve 1221, and then the elastic member 1225 rebounds, which makes the inner cylinder 1222 and the lifting sleeve 1221 reset and move downward, and drive the scraper 101 to enter the fan-shaped groove 3 to avoid blocking the reflective surface;

[0066] Considering that when the lifting sleeve 1221 moves downward, the lifting sleeve 1221 will reverse through the cooperation of the spiral groove 1226 and the plug-in column 1228. In order to prevent the lifting sleeve 1221 from reversing and driving the scraper 101 to rotate in the opposite direction, one end of the lifting sleeve 1221 located at the through hole 212 is set as a rotating end 13, and the rotating end 13 and the main body of the lifting sleeve 1221 are set to unidirectional rotation through a unidirectional rotating member, which can be specifically achieved by components such as a unidirectional bearing, such as Figure 8As shown, the movable reflecting plate 4 and the scraper 101 are both fixedly connected to the outer wall of the rotating end 13 .

[0067] A method for using an anti-interference device for communication equipment based on an ad hoc network comprises the following steps:

[0068] Step 1: First, start the drive motor 1211 to drive the reciprocating drive member to move;

[0069] Step 2: The movement of the reciprocating drive member drives the lifting shaft 1223 to rise, and the inner shaft 1214 is driven to rotate by starting the driving motor 1211. The rotation of the inner shaft 1214 cooperates with the surrounding groove 1216 and the plug pin 1217, so that the inner tube 1213 drives the reciprocating shaft 1215 to reciprocate linearly, and the reciprocating shaft 1215 drives the lifting shaft 1223 to rise;

[0070] Step 3: The lifting shaft 1223 rises and drives the lifting sleeve 1221 to rise, so that the scraper 101 is above the reflective surface. Specifically, the reciprocating shaft 1215 drives the lifting shaft 1223 to rise, and the lifting shaft 1223 drives the top plate 1224 to rise. Since the top plate 1224 is one end of the inner cylinder 1222 at this time, the top plate 1224 will directly push up the inner cylinder 1222, and move the lifting sleeve 1221 upward through the inner cylinder 1222. After the lifting sleeve 1221 moves up, when the lifting sleeve 1221 moves to the upper limit position, the scraper 101 will rise and be above the reflective surface. At the same time, the annular groove 701 overlaps with the latch body 722, and the latch body 722 rebounds under the control of the spring 10, so that the latch body 722 is inserted into the annular groove 701, thereby linearly locking the lifting sleeve 1221.

[0071] Step 4: The reciprocating drive member then moves to drive the lifting shaft 1223 to descend. The descent of the lifting shaft 1223 will cause the lifting sleeve 1221 to rotate through the cooperation of the plug-in column 1228 and the spiral groove 1226 on the movable plate 1227, thereby controlling the rotational movement of the scraper 101 to perform fixed-angle dust removal on the reflective surface. Specifically, the reciprocating shaft 1215 descends, and the reciprocating shaft 1215 drives the lifting shaft 1223 to descend. The descent of the lifting shaft 1223 will cause the top plate 1224 to descend. Since the lifting sleeve 1221 is locked, the lifting sleeve 1221 cannot move in a straight line, and the lifting sleeve 1221 and the inner cylinder 1222 will maintain a fixed height, and the top plate 1224 will be in the inner cylinder. The interior of 1222 descends separately and compresses the elastic member 1225, and while the lifting shaft 1223 descends, it drives the movable disk 1227 to move longitudinally, and the movable disk 1227 cooperates with the plug-in column 1228 and the spiral groove 1226 to make the lifting sleeve 1221 rotate, and the rotation of the lifting sleeve 1221 drives the scraper 101 to rotate, so that the scraper 101 rotates at an angle on the reflecting surface to remove dust from the reflecting surface, and the dust and other impurities are pushed to the fan-shaped groove 3 for discharge. By configuring the spiral groove 1226, when the lifting shaft 1223 moves to the lower limit, the lifting sleeve drives the scraper 101 to rotate and move to the next fan-shaped groove 3;

[0072] When the lifting shaft 1223 drops to the lower limit position, the connecting rope 9 is tightened and the latch body 722 is contracted, so that the latch body 722 is completely contracted into the latch groove 721, and then the latch body 722 is separated from the annular groove 701 to unlock the linear lock of the lifting sleeve 1221. After that, the elastic member 1225 rebounds, and the inner cylinder 1222 and the lifting sleeve 1221 are reset and moved downward, driving the scraper 101 to enter the fan-shaped groove 3 to avoid blocking the reflective surface. With the drive of the driving motor 1211, the scraper 101 is used to remove dust from the reflective surface. At the same time, the scraper 101 is automatically and quickly scraped during the dust removal process to avoid a large amount of impurities sticking to the scraper 101 and affecting the subsequent dust removal work.
