Description

Technical Field

[0001] The present invention relates to the technical field of communication base stations, and in particular to a deicing device and a base station tower. Background Art

[0002] Existing base station equipment will frost and ice when the weather is cold. It is easy to freeze and hang on the signal transmitter box after encountering rain and snow. It is easy to form ice cones hanging under the transmitter box on snowy days. The existing deicing equipment is not enough to quickly clean the ice cones hanging on the transmitter box. If pedestrians fall through the ice cones from the base station, they are likely to be injured. In addition, the ice cones hanging under the signal transmitter box will increase the weight of the transmitter box. When it is windy, the signal transmitter box will be extremely unstable, and the signal emitted by the signal transmitter box will also be unstable. Since the signal transmitter box is installed at the top of the base station tower and is distributed in a circle outside the top of the base station tower, the existing deicing equipment is not enough to quickly clean the ice cones hanging at the bottom of the transmitter box.

[0081] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, but should not be construed as limiting the present invention.

[0082] In view of the problems raised in the background technology, the present invention proposes a deicing device, please refer to Figures 1 to 10, including an installation component 1 and a first de-icing component 2; the installation component 1 is used to install the first de-icing component 2 and make the installation component 1 move along a set trajectory.

[0083] In a specific implementation, the mounting assembly 1 is used to be installed on the base station tower 3 and is located below the signal transmitter box. During installation, the mounting assembly 1 should be located at a certain distance below the transmitter box, as long as the first de-icing assembly 2 can contact the ice cone at the bottom of the transmitter box when working.

[0084] The first de-icing assembly 2 can rotate around a first axis and break the ice cones to be removed during the rotation around the first axis. In a specific implementation, in order to better remove the ice cones at the bottom of the transmitting box, the first axis is usually a vertical line. In the present invention, the first axis is the center line of the base station tower 3.

[0085] When in use, when the ice cone needs to be removed, the first ice removal assembly 2 is controlled to rotate around the first axis, so that the first ice removal assembly 2 can perform ice removal action along the circumferential direction below the launch box, thereby removing the ice cone at the bottom of the launch box.

[0086] In order to realize the deicing function of the first deicing assembly 2, the present invention further discloses a specific structure of the first deicing assembly 2. Specifically, the first deicing assembly 2 includes a support rod 21 and an ice-breaking mechanism 22. The support rod 21 plays a supporting role so that the ice-breaking mechanism 22 can realize the ice-breaking action.

[0087] One end of the support rod 21 is connected to the mounting assembly 1 , and the other end is connected to the ice-breaking mechanism 22 ; the ice-breaking mechanism 22 is used to remove the ice cone at the bottom of the signal transmitting box during the rotation around the first axis.

[0088] In specific implementation, the ice-breaking mechanism 22 can be a fixed component, or a structure that swings or rotates while rotating around the first rotation axis. In this embodiment, the ice-breaking mechanism 22 is a swinging member that achieves ice breaking by swinging. The specific structure of the ice-breaking mechanism 22 is further described below: the ice-breaking mechanism 22 includes a swing rod 221 and an ice-breaking ball 222, that is, the ice-breaking ball 222 can be a metal ball or a non-metal ball with a certain mass. The swing of the ice-breaking ball 222 is used to improve the ice-breaking effect. During the swinging process of the ice-breaking ball 222, it has a certain amount of energy. Therefore, compared with setting the ice-breaking mechanism 22 as a component that only performs circular motion, it has a better ice-breaking effect.

[0089] In a specific implementation, one end of the swing rod 221 is hinged to the support rod 21, and the other end is connected to the ice breaking ball 222; the ice breaking ball 222 can swing around the second axis. That is, in the process of breaking the ice cone, the ice breaking ball 222 swings around the second axis on the one hand, and makes a circular motion around the first axis on the other hand. In a specific implementation, the second axis is a horizontal line.

[0090] In a specific implementation, in order to realize the swing of the swing rod 221, it is only necessary to drive the point on the swing rod 221 to move up and down around the fulcrum. Figure 2 and Figure 4 In the present invention, a method of driving the swing arm 221 to swing is disclosed. Specifically, the ice-breaking mechanism 22 also includes a transmission rod 223 and a driving column 224. In a specific implementation, the driving column 224 is used to drive the swing arm 221 to swing. Specifically, the transmission rod 223 is rotatably connected to the mounting assembly 1; the driving column 224 is fixedly mounted on the top of the transmission rod 223, and a guide groove 225 is provided on the driving column 224; along the circumferential direction, the guide groove 225 is arranged in an undulating manner in the up and down directions. During the rotation of the driving column 224, the swing arm 221 is driven to swing back and forth up and down. Specifically, a guide pin 226 is installed on the swing arm 221, and the guide pin 226 is slidably arranged in the guide groove 225.

[0091] When the transmission rod 223 rotates relative to the mounting assembly 1, the guide pin 226 is driven to slide along the guide slot 225 to drive the swing rod 221 to swing. That is, the rotation of the transmission rod 223 is converted into the swing of the swing rod 221 through the driving column 224.

[0092] In a specific implementation, in order to realize the action of the first de-icing assembly 2, the present invention further includes a first driving mechanism 4, which is used to drive the first de-icing assembly 2 to rotate around the first axis and drive the transmission rod 223 to rotate.

[0093] For specific implementation, please refer to Figure 1 and Figure 2 The installation assembly 1 includes a sleeve 11, and the sleeve 11 is rotatably mounted on the base station tower 3. In a specific implementation, the sleeve 11 can be mounted on the base station tower 3 through a bearing. A first gear ring 12 and a bearing plate 13 are fixedly arranged on the sleeve 11, and the ice breaking mechanism 22 is arranged on the bearing plate 13. The function of the first gear ring 12 is to realize the transmission connection between the first driving mechanism 4 and the sleeve 11, so that the first driving mechanism 4 drives the sleeve 11 to rotate, and then drives the first de-icing assembly 2 connected to the sleeve 11 to rotate around the first axis. Specifically, the center line of the first gear ring 12 coincides with the first axis.

[0094] In some implementations, the first drive mechanism 4 is disposed in the base station tower 3, and an opening is disposed on the side wall of the base station tower 3, and the first drive mechanism 4 is in transmission connection with the first gear ring 12 at the opening. In this way, it is convenient to arrange the first drive mechanism 4 in the base station tower 3, which is convenient for wiring and avoiding rain erosion. In a specific implementation, the first drive mechanism 4 realizes power transmission by meshing with the first gear ring 12 through a transmission gear, and the number of the transmission gears is multiple.

[0095] In the specific implementation, in order to realize the rotation of the transmission rod 223, in the present invention, a second gear ring 31 is also fixedly provided on the base station tower 3; the function of the second gear ring 31 is that when the first de-icing component 2 rotates around the first axis, the second gear ring 31 drives the first de-icing component 2 to rotate, thereby causing the swing rod 221 to swing.

[0096] The bearing plate 13 is located in the second gear ring 31; a slideway 131 is provided on the bearing plate 13. In a specific implementation, the bearing plate 13 is fixedly connected to the sleeve 11. The ice breaking mechanism 22 further includes a mounting plate 227, and the mounting plate 227 is slidably connected to the slideway 131.

[0097] The bottom of the support rod 21 is fixedly connected to the mounting plate 227 , and the transmission rod 223 is rotatably connected to the mounting plate 227 .

[0098] The transmission rod 223 is provided with a driving gear 228, which can mesh with the second gear ring 31. When the driving gear 228 meshes with the second gear ring 31, the driving gear 228 rotates around the first rotation axis and rotates under the action of the second gear ring 31, thereby driving the swing rod 221 to rotate.

[0099] The first driving mechanism 4 is also used to drive the mounting plate 227 to slide along the slideway 131 and make the driving gear 228 mesh with the second gear ring 31. The first driving mechanism 4 drives the mounting plate 227 to slide along the slideway 131 through the locking mechanism 5, which can be referred to below for details.

[0100] In a specific implementation, in order to improve the ice breaking effect, the number of the first de-icing components 2 is multiple, and the driving gears 228 on the multiple first de-icing components 2 have at least two different sizes of pitch circle radii. Preferably, the number of the first de-icing components 2 is three, and the diameters of the driving gears 228 on the three first de-icing components 2 are different, so that the de-icing areas of the multiple first de-icing components 2 can be different, thereby maximizing the de-icing area.

[0101] For specific implementation, please refer to Fig. 9The first driving mechanism 4 is connected to the ice-breaking mechanism 22 via a locking mechanism 5. The locking mechanism 5 is used to collapse or expand the first de-icing assembly 2 toward the first axis direction.

[0102] The locking mechanism 5 has at least two working states. In the first working state, the locking mechanism 5 drives the ice-breaking mechanism 22 to one end of the slide 131 close to the first axis and locks it, and the driving gear 228 is disengaged from the second gear ring 31. In the first working state, the ice-breaking mechanism 22 moves closer to the first axis.

[0103] In the second working state, the locking mechanism 5 drives the ice-breaking mechanism 22 to a position where the slideway 131 is away from the first axis and locks it, and the driving gear 228 meshes with the second gear ring 31. In this state, the ice-breaking mechanism 22 is deployed outward to break ice in a larger area.

[0104] In order to achieve the above functions, the present invention further discloses a locking mechanism 5. In a specific implementation, the locking mechanism 5 can be realized by adding a driving mechanism to realize the switching of the locking mechanism 5 between the first working state and the second working state. In another implementation mode, in order to reduce the driving mechanism, the present invention also proposes a locking mechanism 5, so that the first driving mechanism 4 can realize the switching of the locking mechanism 5 between the first working state and the second working state. Specifically, the locking mechanism 5 includes a stabilizing shaft 51 connected to the inner wall of the sleeve 11 and a moving block 52; a rotating plate 53 is rotatably provided at the upper end of the stabilizing shaft 51, and a locking plate 54 is fixedly connected to the lower end of the stabilizing shaft 51; a first torsion spring is connected between the stabilizing shaft 51 and the rotating plate 53, and the first torsion spring is used to make the rotating plate 53 and the locking plate 54 in a dislocated state. That is, the function of the first torsion spring is to make the locking mechanism 5 be in the first working state or the second working state to realize its locking.

[0105] In a specific implementation, a first card slot 531 , a second card slot 532 and a first connecting slot 533 are provided on the rotating plate 53 , and the first card slot 531 , the second card slot 532 and the first connecting slot 533 all penetrate through the rotating plate 53 .

[0106] The locking plate 54 is provided with a third slot 541, a fourth slot 542, and a second connection slot 543, and the third slot 541 and the fourth slot 542 both penetrate the locking plate 54. In a specific implementation, the rotation plate 53 is aligned with the locking plate 54, which means that the first slot 531 is aligned with the third slot 541, the second slot 532 is aligned with the fourth slot 542, and the first connection slot 533 is aligned with the second connection slot 543.

[0107] In a specific implementation, a locking rod 522 is provided on the moving block 52, and the locking rod 522 slides through the rotating plate 53 and the locking plate 54. The locking rod 522 is used to lock the locking mechanism 5 in the first working state or the second working state.

[0108] A push groove 521 is formed on one side of the moving block 52; one end of the moving block 52 is connected to the mounting plate 227, and the moving block 52 is used to push the mounting plate 227 to slide along the slideway 131. In a specific implementation, when the sleeve 11 rotates, the stabilizing shaft 51 rotates accordingly, and during the rotation process, the locking rod 522 is moved, and the moving block 52 is extended or retracted outward, so that the mounting plate 227 slides along the slideway 131.

[0109] In a specific implementation, in order to realize the control of the moving block 52, the locking mechanism 5 further includes a pillar 55, one end of which is provided with an upper push rod 551, and the lower end of which is provided with a lower push rod 552. The upper push rod 551 is used to push the rotating plate 53 to rotate so that the rotating plate 53 and the locking plate 54 are aligned. The lower push rod 552 is used to drive the moving block 52 to move along the first connecting groove 533 and the second connecting groove 543, so as to realize the switching of the first de-icing assembly 2 between the first working state and the second working state.

[0110] The upper push rod 551 can push the rotating plate 53 to rotate so that the rotating plate 53 can be aligned with the locking plate 54 .

[0111] When the locking mechanism 5 rotates with the sleeve 11 , the lower push rod 552 can enter the push groove 521 and drive the moving block 52 to move.

[0112] For specific implementation, please refer to Figure 2 and Figure 7 The first driving mechanism 4 includes a first motor 41, a first gear 42 and a second gear 43. The first gear 42 is in transmission connection with the first motor 41, the second gear 43 is meshed with the first gear 42, and the second gear 43 is meshed with the first gear ring 12. In this way, the first motor 41 can be used to drive the sleeve 11 to rotate, especially the first motor 41 located in the base station tower 3 drives the external sleeve 11 to rotate around the center line of the base station tower 3.

[0113] In one implementation, in order to remove ice from the surface of the base station tower 3, a second de-icing assembly 6 is further included. The principle of the second de-icing assembly 6 is different from the principle of the first de-icing assembly 2 for removing ice cones. The second de-icing assembly 6 removes ice from the surface of the base station tower 3 by knocking on the base station tower 3 and utilizing vibration.

[0114] Please refer to Figure 2 and Figure 5The second de-icing assembly 6 includes a vibrating rod 61, which is rotatably connected to the base station tower 3 through a pin 64, a vibrating ball 62 is provided at one end of the vibrating rod 61, an elastic member 63 is further provided between the vibrating rod 61 and the base station tower 3, and the connection between the elastic member 63 and the vibrating rod 61 is located between the vibrating ball 62 and the pin 64. That is, the base station tower 3 is continuously knocked by the vibrating ball 62, so as to remove ice on the surface of the base station tower 3.

[0115] In order to achieve the knocking vibration of the second de-icing assembly 6, the present invention further includes a second driving mechanism 7, which is used to intermittently press the end of the vibration rod 61 away from the vibration ball 62. When the second driving mechanism 7 presses the end of the vibration rod 61 away from the vibration ball 62, the vibration ball 62 is away from the surface of the base station tower 3. When the second driving mechanism 7 stops pressing the vibration rod 61, the vibration ball 62 knocks the base station tower 3 under the action of the elastic member 63, thereby generating vibration and achieving de-icing.

[0116] Specifically, the second driving mechanism 7 includes a second motor 71 and a rotating column 72. A first convex block 65 is provided at one end of the vibration rod 61 away from the vibration ball 62, and a second convex block 73 protruding outward is provided on the outer periphery of the rotating column 72; the second convex block 73 is used to intermittently squeeze the first convex block 65 when rotating with the rotating column 72. In order to ensure a good knocking effect, in a specific implementation, the second convex block 73 can be fixedly connected to the rotating column 72 through a rod.

[0117] In a specific implementation, in cold rainy and snowy weather, the first deicing assembly 2 is prone to ice formation, which causes the entire mechanism to be unable to achieve the deicing function. To this end, a protective cover 8 is further included, and the protective cover 8 is installed on the base station tower 3 and is located above the first deicing assembly 2. Specifically, the protective cover 8 is provided on the first deicing assembly 2, which can help prevent rain and snow from entering the first deicing assembly 2 and causing the structure to be frozen.

[0118] Furthermore, a heating coil 81 is provided in the protective cover 8. Before the first de-icing assembly 2 is started to de-ice, the heating coil 81 is used to heat the protective cover 8 and the first de-icing assembly 2 thereunder so as to thaw the protective cover 8.

[0119] In practical applications, if the protective cover 8 is added, the first de-icing assembly 2 will interfere with the protective cover 8 during the process of switching from the first working state to the second working state. Therefore, the present invention further improves the protective cover 8, that is, before starting the first de-icing assembly 2, the protective cover 8 is first moved upward to avoid the first de-icing assembly 2.

[0120] In a specific implementation, a coaxial threaded hole is provided on the rotating column 72 , and a screw threadedly connected to the rotating column 72 is provided on the second motor 71 , thereby forming a lead screw structure.

[0121] The protective cover 8 is connected to the rotating column 72 through a connecting piece, and the connecting piece is rotationally connected to the rotating column 72 and axially fixed. The protective cover 8 is fixedly connected to the connecting piece; a strip hole for the connecting piece to pass through is provided on the base station tower 3. In this way, the protective cover 8 can be moved upward by the second motor 71 to avoid interference with the first de-icing assembly 2.

[0122] In a specific implementation, a limit slot 32 is provided on the base station tower 3, and a limit rod 74 is provided on the rotating column 72. The limit rod 74 can slide in the limit slot 32; the limit rod 74 is connected to the rotating column 72 through a rotating pin 75, and a torsion spring is provided between the limit rod 74 and the rotating pin 75. When the second motor 71 rotates, the protective cover 8 is moved upward by the lead screw structure until the limit rod 74 moves out of the limit slot 32, and the rotating column 72 rotates with the second motor 71. When the second motor 71 reverses, the limit rod 74 enters the limit slot 32, re-forms the lead screw structure, and then moves the rotating column 72 downward, thereby driving the protective cover 8 downward.

[0123] In specific use, with respect to the most detailed embodiment provided above, the working process is as follows.

[0124] When the ice cone at the bottom of the signal transmitter needs to be cleared, the protective cover 8 is heated first to thaw the first ice removal assembly 2, the first driving mechanism 4 and the second driving mechanism 7.

[0125] The second driving mechanism 7 is started to rotate forward. The second driving mechanism 7 drives the protective cover to move up to the uppermost position by using the lead screw structure. At this time, the second protrusion 73 reaches a position substantially flush with the first protrusion 65. At the same time, the limit rod 74 moves out of the limit groove 32, and the limit rod 74 no longer restricts the rotation of the rotating column 72. The second driving mechanism 7 drives the rotating column 72 to rotate and drives the second protrusion 73 to rotate, and realizes that the vibrating ball 62 continuously knocks on the inner wall of the base station tower 3.

[0126] The first motor 41 is started to drive the first gear 42 to rotate, and further drives the sleeve 11 to rotate through the second gear 43, so that the first de-icing assembly 2 rotates around the first axis. During the rotation of the sleeve 11, the locking mechanism 5 is driven to rotate. When the rotating plate 53 and the locking plate 54 rotate to the position of the corresponding support 55, the upper push rod 551 forces the rotating plate 53 to rotate, and the lower push rod 552 provides a force to move the moving block 52. When the rotating plate 53 and the locking plate 54 are aligned, the locking rod 522 moves along the first connecting groove 533 and the second connecting groove 543, and the outer end of the moving block 52 extends outward, thereby driving the first de-icing assembly 2 to move outward. When the driving gear 228 of the first de-icing assembly 2 is engaged with the second gear ring 31, the driving gear 228 rotates. The rotating plate 53 and the locking plate 54 are locked.

[0127] After deicing is completed, the first motor 41 is rotated in the reverse direction, and the lower push rod 552 provides a force to move the moving block 52 in the reverse direction, so as to retract the first deicing assembly 2 inwardly.

[0128] The second motor 71 is rotated in the reverse direction to move the protective cover 8 downward, thereby completing the entire deicing process.

[0129] The present invention further proposes a base station tower, comprising the above-mentioned deicing device, a signal transmitting box is installed on the base station tower 3, and the deicing device is located below the signal transmitting box.

[0130] The present invention cleans the ice cones attached to the bottom of the signal transmission box of the base station equipment through the first de-icing component 2, and the protective cover 8 can protect the first de-icing component 2 and prevent rainwater from entering the interior of the base station tower 3, and can also drive the second de-icing component 6 to clean the ice attached to the base station tower.

[0131] The first de-icing assembly 2 is locked by the provided locking mechanism 5 so that the first de-icing assembly 2 can be stable after being extended.

[0132] The first de-icing assembly 2 can be driven to perform cleaning while being rotated around the base station tower 3. The first de-icing assembly 2 is preheated by a heating coil arranged in the protective cover 8 to prevent the first de-icing assembly 2 from being adhered to other components.

[0133] The above describes in detail the structure, features and effects of the present invention based on the embodiments shown in the drawings. The above is only a preferred embodiment of the present invention, but the present invention is not limited to the scope of implementation shown in the drawings. Any changes made according to the concept of the present invention, or modifications to equivalent embodiments with equivalent changes, which still do not exceed the spirit covered by the description and drawings, should be within the protection scope of the present invention.
