Description

Technical Field

[0001] The present invention relates to the technical field of communication equipment, and particularly to an antenna base station communication equipment. Background Art

[0002] With the rapid development of mobile communication technology, multi-band networks such as 2G, 3G, 4G, and 5G coexist, posing higher requirements for the compatibility and flexibility of base station equipment. Traditional antenna base stations usually adopt signal receiving boards with fixed frequency bands, which are difficult to achieve dynamic switching of multiple frequency bands, resulting in insufficient adaptability of the equipment and relatively high maintenance costs. Moreover, existing base station equipment is prone to damage due to the exposure of the signal receiving board in harsh environments, affecting communication quality and equipment life. In addition, the switching of the signal receiving board is achieved through a mechanical structure, but there are problems such as low positioning accuracy and poor stability, and there is a lack of an effective protection mechanism. The repair and replacement processes of existing equipment are complex, often requiring manual disassembly of the shell, with low efficiency and possible damage to components due to improper operation. Therefore, the present invention provides an antenna base station communication equipment. Summary of the Invention

[0003] Aiming at the defects in the prior art, the present invention provides an antenna base station communication equipment, which overcomes the problems of difficulty in achieving dynamic switching of multiple frequency bands, resulting in insufficient adaptability of the equipment and relatively high maintenance costs.

[0004] To achieve the above object, the present invention provides the following technical solution: An antenna base station communication equipment, including a base, on which a switching component and a calling component are provided. The switching component includes a multi-arm turntable rotatably installed on the base, and a plurality of signal receiving boards are slidably installed on the multi-arm turntable in a circumferential array. The base is also symmetrically provided with a limiting unit, which includes a plurality of driving belt pulleys rotatably installed on the multi-arm turntable. Sector-shaped limiting strip plates are fixedly installed on the driving belt pulleys. Limiting blocks are symmetrically and fixedly provided on the lower surface of the signal receiving boards. The limiting blocks are movably connected to the sector-shaped limiting strip plates. The limiting blocks and the sector-shaped limiting strip plates are used to limit the position of the signal receiving board on the multi-arm turntable. The calling component includes an adjusting turntable. Sector-shaped positioning strip plates are symmetrically and fixedly provided on the signal receiving boards. When the sector-shaped positioning strip plates and the adjusting turntable are engaged, they are rotatably connected. The adjusting turntable is also symmetrically provided with a locking unit, and each locking unit includes a T-shaped sliding plate and a U-shaped sliding plate. The locking unit is used to limit the position of the signal receiving board on the adjusting turntable.

[0005] Further, the multiple signal receiving boards are respectively a 2G board, a 3G board, a 4G board, a 5G board, and spare boards for each frequency band. Protective chamber shells are symmetrically and slidably mounted on the base. Protective chamber covers are also symmetrically and slidably mounted on the base. The protective chamber covers are located directly above the corresponding protective chamber shells. When the two protective chamber shells and the two protective chamber covers are all in the closest positions, a protective chamber is formed among the base, the protective chamber shells, and the protective chamber covers. The signal receiving boards on the multi-arm turntable are all located inside the protective chamber.

[0006] Further, the multiple belt pulleys in the same limiting unit are arranged in a circular array relative to the multi-arm turntable. The number of belt pulleys in the same limiting unit is the same as the number of signal receiving boards. Torsion springs are provided between the belt pulleys and the multi-arm turntable.

[0007] Further, sector-shaped long plates are symmetrically and fixedly arranged on the base. Sector-shaped short plates are also symmetrically and rotatably mounted on the base. When the two ends of the sector-shaped short plates are joined to the corresponding sector-shaped long plates, a complete ring plate is formed between them. Arc-shaped sliding grooves that cooperate with the sector-shaped long plates are provided on the belt pulleys. The sector-shaped long plates are used to limit the positions of the belt pulleys. A transmission group is provided between the two sector-shaped short plates.

[0008] Further, the calling component further includes an annular sliding plate. Heightening long rods are symmetrically and fixedly arranged on the annular sliding plate. The heightening long rods are slidably matched with the base. A heightening screw rod is rotatably mounted on the base. The heightening screw rod and the corresponding heightening long rod form a screw pair. A position-changing toothed ring is rotatably mounted on the annular sliding plate. The position-adjusting turntable is rotatably mounted on the position-changing toothed ring.

[0009] Further, the T-shaped sliding plates and the U-shaped sliding plates are both slidably mounted on the position-adjusting turntable. Springs are provided between the T-shaped sliding plates and the U-shaped sliding plates and the position-adjusting turntable respectively. Positioning short rods are fixedly arranged on the T-shaped sliding plates. Positioning plates are also symmetrically and fixedly arranged on the lower surfaces of the signal receiving boards. Through holes that cooperate with the positioning short rods are provided on the positioning plates. The positioning plates and the positioning short rods are used to limit the positions of the signal receiving boards on the position-adjusting turntable.

[0010] Further, separation sliding plates are symmetrically and slidably mounted on both sides of the position-adjusting turntable. Springs are provided between the separation sliding plates and the position-adjusting turntable respectively. Trapezoidal push blocks and locking short rods are fixedly arranged on the separation sliding plates. Through holes that cooperate with the locking short rods are symmetrically provided on the T-shaped sliding plates. The locking short rods are used to limit the positions of the T-shaped sliding plates. Trapezoidal push blocks are symmetrically and fixedly arranged on the U-shaped sliding plates. The trapezoidal push blocks are used to push the corresponding separation push blocks to move. L-shaped support plates are symmetrically and fixedly arranged on both sides of the base. The L-shaped support plates are used to limit the moving positions of the position-adjusting turntable.

[0011] Furthermore, auxiliary ratchets are fixedly installed on the sides of the sector-shaped short strips, and auxiliary ratchet bars are fixedly installed on the sides of the T-shaped sliding plates. When the auxiliary ratchet bars are engaged with the corresponding auxiliary ratchets, a ratchet mechanism is formed. Under the action of the auxiliary ratchet bars and the auxiliary ratchets, the auxiliary ratchets will not rotate when the auxiliary ratchet bars move downward.

[0012] Furthermore, auxiliary rod one is symmetrically and fixedly arranged on the protective chamber cover, and auxiliary rod two is also symmetrically and fixedly arranged on the protective chamber cover. Four through holes for cooperating with auxiliary rod one are evenly arranged on the annular sliding plate, and auxiliary rod one is used to limit the position of the annular sliding plate. Four through holes for cooperating with auxiliary rod two are evenly arranged on the position-adjusting rotating frame, and auxiliary rod two is used to limit the position of the position-adjusting rotating frame.

[0013] The beneficial effects of the present invention compared with the prior art are as follows: (1) By providing the protective chamber shell and the protective chamber cover, when the device is not in use, the signal receiving board can be completely enclosed in the protective chamber, effectively preventing damage to the device caused by external environments such as dust and rain, and extending the service life of the device. (2) By providing the limiting unit and the locking unit, the position of the signal receiving board on the multi-arm rotating frame and the position-adjusting rotating frame can be ensured to be fixed, improving the stability of the device and the accuracy of signal reception. (3) By adopting a modular design, the protective chamber shell and the protective chamber cover can be slid and unfolded, facilitating the repair or replacement of internal components. At the same time, the overall structure is compact and suitable for installation and use in a limited space. (4) Through the mutual cooperation of the switching component and the calling component, the automatic switching of signal boards in multiple frequency bands can be realized, meeting the requirements of different communication frequency bands and improving the applicability and flexibility of the device.

Detailed implementation manners

[0028] 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.

[0029] Embodiment: Refer to Figures 1 - 13, An antenna base station communication device, including a base 101, a switching component is arranged on the base 101. The switching component includes a multi-arm turntable 119 rotatably installed on the base 101. A switching motor 132 is fixedly installed on the base 101. The output shaft of the switching motor 132 is fixedly connected to the multi-arm turntable 119. A plurality of signal receiving boards 118 are slidably installed on the multi-arm turntable 119 in a circumferential array. The plurality of signal receiving boards 118 are respectively a 2G board, a 3G board, a 4G board, a 5G board and spare boards for each frequency band.

[0030] Protective housing shells 102 are symmetrically and slidably installed on the base 101. Protective housing covers 103 are also symmetrically and slidably installed on the base 101. The protective housing covers 103 are located directly above the corresponding protective housing shells 102. The protective housing covers 103 are slidably matched with the corresponding protective housing shells 102. A double-threaded lead screw one 107 and a double-threaded lead screw two 108 are rotatably installed on the base 101. The threads on both sides of the double-threaded lead screw one 107 respectively form a screw pair with the corresponding protective housing shells 102. The threads on both sides of the double-threaded lead screw two 108 respectively form a screw pair with the corresponding protective housing covers 103. An unfolding motor one 105 and an unfolding motor two 106 are also fixedly installed on the base 101. The output shaft of the unfolding motor one 105 is fixedly connected to the double-threaded lead screw one 107. The output shaft of the unfolding motor two 106 is fixedly connected to the double-threaded lead screw two 108. When the two protective housing shells 102 and the two protective housing covers 103 are both in the position closest to each other, a protection chamber is formed among the base 101, the protective housing shells 102 and the protective housing covers 103.

[0031] In the initial position, the two protective housing shells 102 are in the position closest to each other and the two protective housing covers 103 are in the position closest to each other. At this time, a protection chamber is formed among the base 101, the protective housing shells 102 and the protective housing covers 103. The signal receiving boards 118 on the multi-arm turntable 119 are all located inside the protection chamber. That is, the unused signal receiving boards 118 are covered and protected through the protection chamber. When the internal components of the protection chamber need to be repaired or replaced, the protective housing shells 102 and the protective housing covers 103 are both in the position farthest from each other, that is, the protective housing shells 102 and the protective housing covers 103 are unfolded, so as to facilitate the repair and replacement of the internal components of the protection chamber.

[0032] The base 101 is also symmetrically provided with limiting units. Each limiting unit includes a plurality of transmission pulleys 137 rotatably mounted on the multi-arm bracket 119. The plurality of transmission pulleys 137 in the same limiting unit are arranged in a circumferential array relative to the multi-arm bracket 119. The number of transmission pulleys 137 in the same limiting unit is the same as the number of signal receiving boards 118. A torsion spring is provided between each transmission pulley 137 and the multi-arm bracket 119. One end of the torsion spring is fixedly connected to the multi-arm bracket 119, and the other end of the torsion spring is fixedly connected to the transmission pulley 137. A sector-shaped limiting strip 140 is fixedly mounted on each transmission pulley 137. The sector-shaped limiting strip 140 has the same circumferential direction as the transmission pulley 137. Limiting blocks 139 are symmetrically and fixedly provided on the lower surface of the signal receiving board 118. The limiting blocks 139 are movably connected to the sector-shaped limiting strips 140. The limiting blocks 139 and the sector-shaped limiting strips 140 are used to limit the position of the signal receiving board 118 on the multi-arm bracket 119.

[0033] In the initial position, the torsion spring between the transmission pulley 137 and the multi-arm bracket 119 is not compressed. At this time, each sector-shaped limiting strip 140 is in a engaged state with the corresponding limiting block 139. Under the action of the limiting block 139 and the sector-shaped limiting strip 140, the signal receiving board 118 cannot move relative to the multi-arm bracket 119 at this time, that is, the position of the signal receiving board 118 on the multi-arm bracket 119 is fixed.

[0034] Sector-shaped long plates 138 are symmetrically and fixedly provided on the base 101. Arc-shaped chutes for cooperating with the sector-shaped long plates 138 are provided on each transmission pulley 137. Sector-shaped short plates 136 are also symmetrically and rotatably mounted on the base 101. When the two ends of the sector-shaped short plate 136 are engaged with the corresponding sector-shaped long plates 138, a complete ring plate is formed between them. The sector-shaped long plates 138 are used to limit the position of the transmission pulley 137. A transmission group is provided between the two sector-shaped short plates 136.

[0035] The transmission group includes a transmission shaft 129, two transmission belts 128, and four pulleys. The transmission shaft 129 is rotatably mounted on the base 101. Two of the four pulleys in the transmission are fixedly mounted on the transmission shaft 129, and the other two pulleys are respectively fixedly mounted on the sides of the corresponding sector-shaped short plates 136. The transmission belts 128 are arranged between the pulleys on the sector-shaped short plates 136 and the corresponding pulleys on the transmission shaft 129. An auxiliary motor 141 is fixedly mounted on the base 101. The output shaft of the auxiliary motor 141 is fixedly connected to the transmission shaft 129.

[0036] Start the auxiliary motor 141 to drive the transmission shaft 129 to rotate. Under the action of the transmission group, the two sector-shaped short strip plates 136 rotate synchronously, that is, the position of the sector-shaped short strip plates 136 is adjusted so that both ends of the sector-shaped short strip plates 136 are engaged with the sector-shaped long strip plate 138. At this time, the sector-shaped short strip plates 136 and the sector-shaped long strip plate 138 form a complete ring plate. Then start the switching motor 132 to drive the multi-arm turret 119 to rotate, and then the signal receiving plate 118 on the multi-arm turret 119 rotates synchronously. The corresponding belt pulley 137 of the signal receiving plate 118 rotates relative to the ring plate formed by the sector-shaped short strip plates 136 and the sector-shaped long strip plate 138, so that the required signal receiving plate 118 rotates to directly above the base 101. At this time, the two corresponding belt pulleys 137 of the signal receiving plate 118 are respectively engaged with the corresponding sector-shaped short strip plates 136, and the corresponding belt pulley 137 of the signal receiving plate 118 is disengaged from the engagement with the sector-shaped long strip plate 138, that is, the axis of the corresponding belt pulley 137 of the signal receiving plate 118 is on the same straight line as the center line of the rotation connection between the sector-shaped short strip plate 136 and the base 101. At this time, continue to start the auxiliary motor 141 to drive the two sector-shaped short strip plates 136 to rotate synchronously, and then the two corresponding belt pulleys 137 of the signal receiving plate 118 rotate synchronously. The torsion spring between the belt pulley 137 and the multi-arm turret 119 is compressed, and then the two corresponding sector-shaped limit strip plates 140 rotate synchronously, and finally the two corresponding sector-shaped limit strip plates 140 are disengaged from the engagement with the corresponding limit blocks 139, that is, the locking of the position of the signal receiving plate 118 is released. At this time, pull the signal receiving plate 118 upward, and the signal receiving plate 118 can slide relative to the multi-arm turret 119, so that the signal receiving plate 118 can be removed from the multi-arm turret 119.

[0037] A calling component is provided on the base 101. The calling component includes an adjusting turret 115. The calling component further includes an annular slide plate 111. The height-adjusting long rods 110 are symmetrically and fixedly arranged on the annular slide plate 111. The height-adjusting long rods 110 are slidably matched with the base 101. A height-adjusting screw rod 109 is rotatably installed on the base 101. The height-adjusting screw rod 109 and the corresponding height-adjusting long rod 110 form a screw pair. A height-adjusting motor 104 is fixedly installed on the base 101. The output shaft of the height-adjusting motor 104 is fixedly connected to the height-adjusting screw rod 109. A position-changing gear ring 112 is rotatably installed on the annular slide plate 111. A position-changing motor 117 is further fixedly installed on the annular slide plate 111. A position-changing gear 116 is fixedly installed on the output shaft of the position-changing motor 117. The position-changing gear 116 and the position-changing gear ring 112 are engaged to form a gear pair. The adjusting turret 115 is rotatably installed on the position-changing gear ring 112. A position-adjusting motor 120 is fixedly installed on the position-changing gear ring 112. The output shaft of the position-adjusting motor 120 is fixedly connected to the adjusting turret 115.

[0038] Start the height adjustment motor 104 to drive the height adjustment lead screw 109 to rotate, which causes the height adjustment lead screw 109 to move up and down relative to the base 101. Consequently, the annular slide plate 111 moves up and down relative to the base 101, and the components on the annular slide plate 111 move synchronously. Start the position conversion motor 117 to drive the position conversion gear 116 to rotate, which causes the position conversion ring gear 112 to rotate relative to the annular slide plate 111. Start the position adjustment motor 120 to drive the position adjustment support 115 to rotate, which causes the position adjustment support 115 to rotate relative to the position conversion ring gear 112. The center line of the rotational connection between the position adjustment support 115 and the position conversion ring gear 112 is perpendicular to the axis of the position conversion ring gear 112. That is, under the action of the position conversion motor 117 and the position adjustment motor 120, the position of the position adjustment support 115 can be adjusted.

[0039] Sector-shaped positioning strip plates 134 are symmetrically and fixedly arranged on the signal receiving board 118. The sector-shaped positioning strip plates 134 are rotatably connected when they are engaged with the position adjustment support 115. Locking units are also symmetrically arranged on the position adjustment support 115. Each locking unit includes a T-shaped slide plate 121 and a U-shaped slide plate 122. The locking units are used to restrict the position of the signal receiving board 118 when it is on the position adjustment support 115. The T-shaped slide plate 121 and the U-shaped slide plate 122 are both slidably mounted on the position adjustment support 115, and springs are arranged between the T-shaped slide plate 121 and the U-shaped slide plate 122 and the position adjustment support 115.

[0040] Positioning short rods 135 are fixedly arranged on the T-shaped slide plates 121. Positioning plates 133 are also symmetrically and fixedly arranged on the lower surface of the signal receiving board 118. Through holes that cooperate with the positioning short rods 135 are arranged on the positioning plates 133. The positioning plates 133 and the positioning short rods 135 are used to restrict the position of the signal receiving board 118 on the position adjustment support 115. When the signal receiving board 118 is on the position adjustment support 115, the spring between the T-shaped slide plate 121 and the position adjustment support 115 is not compressed. At this time, the positioning short rod 135 and the corresponding positioning plate 133 are in a joined state. That is, under the action of the positioning plate 133, the sector-shaped positioning strip plate 134, and the positioning short rod 135, the signal receiving board 118 cannot move relative to the position adjustment support 115 at this time, thus realizing the fixation of the position of the signal receiving board 118.

[0041] On both sides of the position-adjusting turntable 115, separation slides 126 are symmetrically and slidably installed. Springs are provided between the separation slides 126 and the position-adjusting turntable 115. Separation push blocks (125) and locking short rods 127 are fixedly provided on the separation slides 126. Through holes cooperating with the locking short rods 127 are symmetrically provided on the T-shaped slide 121. The locking short rods 127 are used to limit the position of the T-shaped slide 121. When the positioning plate 133, the sector-shaped positioning strip 134, and the positioning short rod 135 complete the fixation of the position of the signal receiving plate 118, the springs between the separation slides 126 and the position-adjusting turntable 115 are not compressed. At this time, the locking short rods 127 are engaged with the corresponding through holes on the T-shaped slide 121, that is, the locking short rods 127 are engaged with the corresponding T-shaped slide 121. Under the action of the locking short rods 127, the T-shaped slide 121 cannot move up and down relative to the position-adjusting turntable 115. That is, under the action of the locking short rods 127, the position of the T-shaped slide 121 is locked, thereby improving the stability of the signal receiving plate 118 on the position-adjusting turntable 115.

[0042] Trapezoidal push blocks 124 are symmetrically and fixedly provided on the U-shaped slide 122. The trapezoidal push blocks 124 are used to push the corresponding separation push blocks 125 to move. When the locking short rods 127 complete the locking of the position of the T-shaped slide 121, the spring between the U-shaped slide 122 and the position-adjusting turntable 115 is not compressed. At this time, the U-shaped slide 122 is at the position closest to the lower surface of the base 101 on the position-adjusting turntable 115, that is, at this time, the trapezoidal push blocks 124 do not contact the corresponding separation push blocks 125.

[0043] Reference Figure 8 , auxiliary ratchets 131 are fixedly installed on the sides of the sector-shaped short strips 136. Auxiliary ratchet bars 123 are fixedly installed on the sides of the T-shaped slide 121. When the auxiliary ratchet bars 123 are engaged with the corresponding auxiliary ratchets 131, a ratchet mechanism is formed. Under the action of the auxiliary ratchet bars 123 and the auxiliary ratchets 131, the auxiliary ratchets 131 will not rotate when the auxiliary ratchet bars 123 move downward. That is, when the auxiliary ratchets 131 are driven to rotate clockwise, the auxiliary ratchet bars 123 move downward, and when the auxiliary ratchets 131 are driven to rotate counterclockwise, the auxiliary ratchet bars 123 will not move. L-shaped support plates 130 are symmetrically and fixedly provided on both sides of the base 101. The L-shaped support plates 130 are used to limit the moving position of the position-adjusting turntable 115.

[0044] When it is necessary to remove a certain signal receiving board 118 on the multi-arm turret 119, first drive the multi-arm turret 119 to rotate so that the sector positioning strip plates 134 on the signal receiving board 118 are not located directly below the positioning turret 115. Then start the positioning motor 120 to drive the positioning turret 115 to rotate so that the positioning turret 115 is in a horizontal state. Then start the transposition motor 117 to drive the transposition gear ring 112 to rotate, so that the center line at the rotation connection of the transposition gear ring 112 and the positioning turret 115 is on the same straight line as the center line of the multi-arm turret 119.

[0045] Then start the height adjustment motor 104 to drive the annular slide plate 111 to move downward. First, make the lower end surface of the U-shaped slide plate 122 contact the corresponding two L-shaped support plates 130. The annular slide plate 111 continues to move downward, and the spring between the U-shaped slide plate 122 and the positioning turret 115 is compressed. The positioning turret 115 moves downward relative to the U-shaped slide plate 122, that is, the trapezoidal push block 124 moves upward relative to the corresponding separation push block 125. Under the action of the trapezoidal push block 124, the separation push block 125 moves away from the corresponding T-shaped slide plate 121. The separation slide plate 126 and the locking short rod 127 move synchronously. The spring between the separation slide plate 126 and the positioning turret 115 is compressed. Finally, the positioning turret 115 moves to contact the upper surface of the L-shaped support plate 130. At this time, the locking short rod 127 disengages from the contact with the T-shaped slide plate 121 under the action of the trapezoidal push block 124 and the separation push block 125, that is, the locking short rod 127 releases the restriction on the position of the T-shaped slide plate 121. And at this time, the auxiliary ratchet bar 123 and the corresponding auxiliary ratchet wheel 131 are engaged to form a ratchet mechanism. At this time, the sector short strip plate 136 is not engaged with the corresponding sector long strip plate 138 to form a complete ring plate.

[0046] Then start the auxiliary motor 141 to drive the transmission shaft 129 to rotate, that is, to make the two sector short strip plates 136 rotate synchronously. The auxiliary ratchet wheels 131 on the sector short strip plates 136 also rotate synchronously. At this time, the auxiliary ratchet bar 123 moves downward under the action of the auxiliary ratchet wheel 131. The T-shaped slide plate 121 moves downward synchronously. The positioning short rod 135 on the T-shaped slide plate 121 also moves downward synchronously. Finally, the sector short strip plate 136 rotates to be engaged with the sector long strip plate 138 to form a complete ring plate. At this time, the positioning short rod 135 moves to the position closest to the lower surface of the base 101.

[0047] Then start the switching motor 132 to drive the multi-arm turntable 119 to rotate, so that the signal receiving board 118 to be used rotates directly above the base 101. At this time, the sector positioning strip 134 on the signal receiving board 118 engages with the position adjusting turntable 115, and the through hole on the positioning plate 133 is not directly above the corresponding positioning short rod 135. Then continue to start the auxiliary motor 141 to drive the two auxiliary ratchets 131 to rotate in the reverse direction. The auxiliary ratchet bar 123 moves upward under the action of the spring between the T-shaped slide plate 121 and the position adjusting turntable 115. Under the action of the sector short strip 136, the sector limit strip 140 disengages from the engagement with the limit block 139, and the positioning short rod 135 engages with the positioning plate 133. The auxiliary ratchet 131 continues to rotate, and finally the positioning short rod 135 completely engages with the positioning plate 133.

[0048] Then start the height adjusting motor 104 to drive the annular slide plate 111 to move upward, and the position adjusting turntable 115 moves upward synchronously. The signal receiving board 118 moves upward synchronously under the action of the positioning plate 133, the sector positioning strip 134, and the positioning short rod 135. At this time, the auxiliary ratchet 131 continues to rotate to make way for the movement of the auxiliary ratchet bar 123. Finally, the auxiliary ratchet bar 123 completely disengages from the engagement with the auxiliary ratchet 131. And during the upward movement of the position adjusting turntable 115, the spring between the U-shaped slide plate 122 and the position adjusting turntable 115 starts to recover, that is, at this time the U-shaped slide plate 122 moves downward relative to the position adjusting turntable 115, and the trapezoidal push block 124 gradually disengages from the contact with the separating push block 125, that is, the locking short rod 127 re-engages with the T-shaped slide plate 121. Under the action of the locking short rod 127, the position of the T-shaped slide plate 121 is locked, thereby improving the stability of the signal receiving board 118 on the multi-arm turntable 119.

[0049] Auxiliary rod one 113 is symmetrically and fixedly arranged on the protective cover 103. Auxiliary rod two 114 is also symmetrically and fixedly arranged on the protective cover 103. Four through holes matching with the auxiliary rod one 113 are evenly arranged on the annular slide plate 111. The auxiliary rod one 113 is used to limit the position of the annular slide plate 111. Four through holes matching with the auxiliary rod two 114 are evenly arranged on the position adjusting turntable 115. The auxiliary rod two 114 is used to limit the position of the position adjusting turntable 115.

[0050] In the initial position, the protective cover 102 and the protective cover 103 are at the closest position. The annular slide plate 111 is at the position closest to the lower surface of the base 101. The four through holes on the annular slide plate 111 are respectively engaged with the corresponding auxiliary rod one 113. The four through holes on the position adjusting turntable 115 are respectively engaged with the corresponding auxiliary rod two 114. Under the action of the auxiliary rod one 113, the stability of the annular slide plate 111 when not in use is improved. Under the action of the auxiliary rod two 114, the stability of the position adjusting turntable 115 when not in use is improved, thereby improving the stability of the equipment during transportation.

[0051] Working principle: When using the device, first start the height-adjusting motor 104 to move the annular slide plate 111 upward, so that the annular slide plate 111 disengages from the engagement with the first auxiliary rod 113 and the position-adjusting turntable 115 disengages from the engagement with the second auxiliary rod 114. Then start the second unfolding motor 106 to move the two protective cover plates 103 to the farthest positions from each other. At this time, both the first auxiliary rod 113 and the second auxiliary rod 114 move to both sides of the position-changing gear ring 112 and will not affect the movement of the annular slide plate 111 and the position-changing gear ring 112.

[0052] Then start the height-adjusting motor 104 to move the annular slide plate 111 downward. Finally, the position-adjusting turntable 115 contacts the upper surface of the L-shaped support plate 130. At this time, the T-shaped slide plate 121 is released from the restriction of the locking short rod 127 and can move up and down relative to the position-adjusting turntable 115. Then start the auxiliary motor 141 to drive the auxiliary ratchet wheel 131 and the sector-shaped short strip plate 136 to rotate synchronously, so that the sector-shaped short strip plate 136 and the sector-shaped long strip plate 138 are engaged to form a ring plate, and the T-shaped slide plate 121 and the positioning short rod 135 move to the positions closest to the lower surface of the base 101.

[0053] Then start the switching motor 132 to drive the multi-arm turntable 119 to rotate, so that the signal receiving board 118 to be used rotates to directly above the base 101. At this time, the corresponding belt pulley 137 of this signal receiving board 118 is engaged with the corresponding sector-shaped short strip plate 136. Continue to start the auxiliary motor 141 to drive the auxiliary ratchet wheel 131 and the sector-shaped short strip plate 136 to rotate synchronously. First, make the sector-shaped limit strip plate 140 disengage from the engagement with the limit block 139. At this time, the positioning short rod 135 contacts the corresponding positioning plate 133 again. Then drive the annular slide plate 111 to move upward, and the position-adjusting turntable 115 moves upward synchronously. The auxiliary ratchet wheel 131 continues to rotate to make way for the movement of the auxiliary ratchet bar 123. Finally, the positioning short rod 135 and the positioning plate 133 are completely engaged. At this time, the auxiliary ratchet wheel 131 and the auxiliary ratchet bar 123 are disengaged from the engagement, that is, the call of this signal receiving board 118 is realized.

[0054] After the call of the signal receiving board 118 is completed, move the two protective cover plates 103 to the closest positions to each other, that is, protect the remaining signal receiving boards 118 on the multi-arm turntable 119. Then adjust the position of the position-adjusting turntable 115 through the height-adjusting motor 104, the position-changing motor 117, and the position-adjusting motor 120, so as to adjust the signal receiving direction of the signal receiving board 118.

[0055] If it is necessary to replace the signal receiving board 118 of other frequency bands or the spare one, first repeat the above steps to place the signal receiving board 118 on the position-adjusting turntable 115 back on the multi-arm turntable 119, and then install the new signal receiving board 118 on the position-adjusting turntable 115.

[0056] The present invention is not limited to the above specific embodiments. Those skilled in the art can make various changes starting from the above concepts without creative efforts, and all such changes fall within the protection scope of the present invention.
