DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Reference Figure 1-7 A tower support base includes a base 1 and a communication supporting device 2. A tower column 3 is arranged on the communication supporting device 2. A groove 4 for placing the communication supporting device 2 is opened on the side wall of the base 1.

[0032] The supporting mechanism includes two slide grooves 5 opened at the upper end of the base 1, and a plurality of slide rods 6 are fixedly connected to the inner wall of the slide groove 5, and the side walls of the plurality of slide rods 6 are slidably connected to the first plate 7 together, and a protective frame 8 is fixedly connected to the upper end of the first plate 7, and a clamping plate 9 is fixedly connected to the upper end of the protective frame 8. The side wall of the protective frame 8 is semicircular near the tower column 3, and the lower end of the first plate 7 is connected to a movable plate 12 through a connecting mechanism, and a reciprocating screw 13 is threadedly connected to the side wall of the movable plate 12. A second plate 14 is fixedly connected to the bottom of the slide groove 5, and a cross bar 15 is rotatably connected to the side wall of the second plate 14, and the end of the cross bar 15 away from the second plate 14 is connected to one end of the reciprocating screw 13 through a mounting plate 16.

[0033] Furthermore, the threads of the side walls of the two reciprocating screws 13 are arranged oppositely, and the reciprocating screw 13 can be detachably connected to the cross bar 15, so that the reciprocating screw 13 can be replaced, and the thread length on the surface of the reciprocating screw 13 can be adjusted, so that the support mechanism can support towers of different degrees, increasing its scope of use, and when supporting, only two protective frames 8 need to be close at the same time, which simplifies the process compared to the use of multiple support rods in the prior art;

[0034] In addition, the two protection frames 8 can fully wrap the communication supporting equipment 2 to effectively protect it, avoiding the problem in the prior art that after the supporting base supports the tower column, there is a gap between the support rods, that is, the protection effect on the supporting equipment is not obvious at this time.

[0035] The driving mechanism is used to drive the cross bar 15 to rotate. The driving mechanism includes two one-way bearings 18. The inner walls of the two slide grooves 5 are connected to the rotating shaft 17 for common rotation. The inner wall of the rotating shaft 17 is fixedly connected to the inner ring of the one-way bearing 18. The outer ring of the one-way bearing 18 is fixedly connected to the end of the cross bar 15 away from the mounting plate 16 through a U-shaped plate.

[0036] The driving mechanism also includes a driving groove 19 opened on the side wall of the base 1, a motor 20 is fixedly connected to the upper end of the base 1, a movable end of the motor 20 is located in the driving groove 19 and is fixedly connected to a first bevel gear 21, and a side wall of the rotating shaft 17 located in the driving groove 19 is fixedly connected to a second bevel gear 22, and the first bevel gear 21 and the second bevel gear 22 are meshed.

[0037] It should be noted that when the motor 20 rotates clockwise, the shaft 17 will rotate counterclockwise, and the inner ring of the one-way bearing 18 will drive the outer ring to rotate. When the motor 20 rotates counterclockwise, the shaft 17 will rotate clockwise, and the inner ring of the one-way bearing 18 will not drive the outer ring to rotate.

[0038] And after the clamping plate 9 supports and clamps the tower column 3, the movable plate 12 is located at the thread of the reciprocating screw 13 closest to the mounting plate 16. When it is needed to be separated later, the motor 20 only needs to rotate clockwise again, and each time the movable plate 12 moves to the position at the outermost thread of the reciprocating screw 13.

[0039] The connecting mechanism includes a through slot 23 provided on the side wall of the first plate 7 , a mounting plate 24 matching the through slot 23 is fixedly connected to the upper end of the movable plate 12 , and the side wall of the first plate 7 is connected to the side wall of the mounting plate 24 via a plurality of bolts 40 .

[0040] A circular hole 10 is provided on the side wall of the protective frame 8 to provide ventilation and heat dissipation for the communication supporting equipment 2. A filter 11 is fixedly connected to the inner wall of the circular hole 10. A rotating rod 26 is rotatably connected to the top of the protective frame 8 through a third plate 25. A plurality of cleaning plates 27 are fixedly connected to the side wall of the rotating rod 26 away from the third plate 25. A plurality of bristles 28 that fit the side wall of the filter 11 are fixedly connected to the side wall of the cleaning plate 27.

[0041] The upper end of the base 1 is rotatably connected to a sleeve 30 through a fourth plate 29, and the sleeve 30 is provided with a plurality of slots 31. The side wall of the rotating rod 26 is fixedly connected to a plurality of rods 32 corresponding to the plurality of slots 31, and the plurality of rods 32 are respectively located in the plurality of slots 31, so that during the horizontal movement of the protective frame 8, the plurality of rods 32 are still located in the plurality of slots 31, so that the rotation of the sleeve 30 can still drive the rotating rod 26 to rotate, and then the plurality of bristles 28 can clean the surface of the filter 11 to increase its ventilation effect. The side wall of the rotating shaft 17 is fixedly connected to a first wheel 33, and the side wall of the sleeve 30 is fixedly connected to a second wheel 34, and a synchronous belt is connected between the first wheel 33 and the second wheel 34.

[0042] A gear 35 is fixedly connected to the side wall of the cross bar 15, a limiting groove 36 is provided at the lower end of the base 1, a slider 37 is slidably connected to the inner wall of the limiting groove 36, the lower end of the slider 37 is elastically connected to the bottom of the limiting groove 36 through a plurality of conductive springs 38, an arc-shaped tooth plate 39 is fixedly connected to the upper end of the slider 37, the side wall of the gear 35 is meshed with the side wall of the arc-shaped tooth plate 39, and the conductive spring 38 and the motor 20 are electrically connected to the external power supply through a diode.

[0043] It should be noted that the conductive spring 38 interacts with the external current to generate different sizes of pulling force to control the tensile deformation and movement state of the conductive spring 38. At the same time, the diode only allows forward current to pass, that is, when the forward current is passed, the motor 20 rotates clockwise, and the conductive spring 38 contracts, so that the gear 35 is separated from the arc-shaped tooth plate 39, and does not affect the rotation of the cross bar 15. When the reverse current is passed, the motor 20 rotates counterclockwise, and the conductive spring 38 stretches, so that the gear 35 is engaged with the arc-shaped tooth plate 39, which hinders the rotation of the cross bar 15, thereby ensuring the support stability of the two protective frames 8 and the two clamping plates 9 on the tower column 3.

[0044] When supporting the tower, first move the base 1 through the groove 4 to the communication supporting equipment 2, at which time the communication supporting equipment 2 and the tower column 3 are both located in the base 1;

[0045] Then, the displacement of the two protection frames 8 can be adjusted according to the thickness of the tower column 3. The specific steps are as follows:

[0046] First, the mounting plate 16 is disassembled to complete the connection between the reciprocating screw 13 and the cross bar 15, and then the plurality of bolts 40 are rotated to separate the mounting plate 24, so that the movable plate 12 can be removed from the slide groove 5, and then the replaced movable plate 12 equipped with the reciprocating screw 13 can be placed in the slide groove 5 and installed;

[0047] After replacement, the motor 20 is rotated clockwise, and the conductive spring 38 is energized and contracted, so that the gear 35 is separated from the arc-shaped toothed plate 39, and the rotation of the crossbar 15 is not affected;

[0048] Then, under the action of the first bevel gear 21 and the second bevel gear 22, the rotating shaft 17 will rotate counterclockwise, and then the inner ring of the one-way bearing 18 will drive its outer ring to rotate, so that the two cross bars 15 drive the two reciprocating screws 13 to rotate, so that the two moving plates 12 are close to each other, and then the two first plates 7 drive the two protection frames 8 and the two clamping plates 9 to be close to each other to support the tower column 3. At this time, the moving plate 12 is located at the thread of the reciprocating screw 13 closest to the mounting plate 16. At the same time, the two protection frames 8 can also provide comprehensive protection for the communication supporting equipment 2;

[0049] After the support, the motor 20 is rotated counterclockwise, and the conductive spring 38 is disconnected and extended, so that the gear 35 is engaged with the arc-shaped toothed plate 39, and the rotation of the crossbar 15 is blocked;

[0050] At this time, the rotating shaft 17 will rotate clockwise, and the inner ring of the one-way bearing 18 will not drive the outer ring to rotate, so as to maintain the support stability of the tower column 3. During the rotation of the rotating shaft 17, the first wheel 33 will drive the second wheel 34 to rotate through the synchronous belt, and then the sleeve 30 will drive the rotating rod 26 to rotate through the card slot 31 and the card rod 32, so that the multiple bristles 28 can clean the surface of the filter screen 11 to increase its ventilation effect.

[0051] When the communication supporting device 2 needs to be operated later, it is only necessary to continue to rotate the motor 20 clockwise to move the two protection frames 8 away from each other.

[0052] A communication tower comprises any of the tower support bases described above.

[0053] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
