DETAILED DESCRIPTION

[0017] In order to better understand the technical content of the present invention, a specific embodiment is provided below, and the present invention is further described in conjunction with the accompanying drawings.

[0018] See also Figures 1 to 4The present invention provides a remote monitoring device for a communication base station, comprising a communication pole tower 1, an insulating ring 2, a metal bar 3, a communication base station 4, a metal bracket 5 and a connection detection mechanism, wherein the insulating ring 2 is rotatably sleeved on the outer wall of the communication pole tower 1, and the metal bar 3 is embedded in the outer surface of the insulating ring 2 at intervals. The communication base station 4 is arranged on the outside of the insulating ring 2 and is connected to the metal bar 3 through the metal bracket 5; the connection detection mechanism comprises a rotating mechanism, a conductive interface 6, a fixing ring 7, a power supply box 8, a first electric push rod 9, a lifting plate 10, an electrode head 11, a spring wire 12, a second electric push rod 13, an opening and closing current clamp 14 and a main control unit 15, the rotating mechanism is used to drive the insulating ring 2 to rotate, the conductive interface 6 is arranged on the top surface of the insulating ring 2, and is electrically connected to the top of the metal bar 3, The fixed ring 7 is sleeved on the communication pole tower 1 and is located above the insulating ring 2. The power box 8 is arranged on the top surface of the fixed ring 7. The first electric push rod 9 is arranged on the bottom surface of the fixed ring 7, and its output shaft is connected to the top surface of the lifting plate 10. The electrode head 11 is arranged on the bottom surface of the lifting plate 10 and is located above the rotation path of the conductive interface 6. The spring wire 12 connects the electrode head 11 and the power box 8. The second electric push rod 13 is tilted on the outer circumference of the fixed ring 7, and its output shaft is connected to the top of the opening and closing current clamp 14. The metal bracket 5 is located on the lifting path of the opening and closing current clamp 14. The main control unit 15 is arranged on the top surface of the fixed ring 7 and is electrically connected to the communication base station 4, the rotating mechanism, the power box 8, the first electric push rod 9, the second electric push rod 13 and the opening and closing current clamp 14 respectively.

[0019] A remote monitoring device for a communication base station of the present invention is provided with an insulating ring 2 on the outside of a communication tower 1. The insulating ring 2 is rotatably connected to the communication tower 1. A rotating mechanism can drive the insulating ring 2 to rotate. A plurality of metal bars 3 are inlaid at intervals on the outer wall of the insulating ring 2, wherein two metal bars 3 form a group. On the outside of a group of metal bars 3, a communication base station 4 is connected through a metal bracket 5 to fix the communication base station 4. The present invention preferably has 8 metal bars 3, so the number of communication base stations 4 is 4, which are distributed in four directions of the communication tower 1. Data in different directions can be stably transmitted and received, thereby ensuring normal signal transmission of users near the communication tower 1.

[0020] The end of the metal bracket 5 is connected to the metal bar 3, and contact resistance is formed at the connection. In daily use, due to wind or external force impact, the contact position may become loose or fall off, causing the contact resistance to change. Therefore, by detecting the contact resistance, it is possible to determine whether the connection is tight. A conductive interface 6 is set on the top of the insulating ring 2, and its number is consistent with the number of metal bars 3, and each conductive interface 6 is electrically connected to the metal bar 3. A fixing ring 7 is also set on the communication tower 1, and its height is greater than the insulating ring 2. The first electric push rod 9 on the bottom of the fixing ring 7 can drive the electrode head 11 to descend through the lifting plate 10, so that the electrode head 11 can be connected to the conductive interface 6, thereby the power box 8 The current can be transmitted to the metal strip 3 and the metal bracket 5 through the electrode head 11 and the conductive interface 6, and a group of metal strips 3 are connected to the metal bracket 5, so a loop can be formed. The second electric push rod 13 on the outer wall of the fixed ring 7 can drive the inclined opening and closing current clamp 14 to descend, and open the opening and closing current clamp 14 and put it on the metal bracket 5 to collect the current flowing on the metal bracket 5. The main control unit 15 can reversely infer the resistance value through the current size, and thereby obtain the size of the contact resistance, so as to determine whether the connection is loose. If there is looseness, data can be sent to a distant monitoring center through the communication base station 4 to facilitate timely repair and maintenance to ensure the stable operation of the communication base station 4.

[0021] Preferably, the metal bracket 5 includes a metal backplate 16 and a metal connecting rod 17. The metal backplate 16 is arranged on the side wall of the communication base station 4. One end of the metal connecting rod 17 is connected to the metal backplate 16, and the other end is connected to the metal bar 3. The metal connecting rod 17 is located below the moving path of the opening and closing current clamp 14.

[0022] The two ends of the metal connecting rod 17 are respectively connected to the metal back plate 16 and the metal strip 3, thus forming a loop of one side metal strip 3-one side metal connecting rod 17-metal back plate 16-the other side metal connecting rod 17-the other side metal strip 3. The resistance value can be judged by the current in the loop, and the contact resistance can be reversely deduced to assess whether there is a loose problem. When collecting the current value, the open current clamp will descend to the metal connecting rod 17 and be sleeved on the outside of the metal connecting rod 17 to collect the current by induction to avoid damaging the metal connecting rod 17.

[0023] Preferably, the metal bracket 5 further includes a metal connecting plate 18 and a screw 19 . The metal connecting plate 18 is arranged at one end where the metal connecting rod 17 is connected to the metal bar 3 , and is provided with a threaded hole 20 . The screw 19 is connected to the metal bar 3 through the threaded hole 20 .

[0024] The end of the metal connecting rod 17 is detachably connected to the metal bar 3. After the metal connecting plate 18 contacts the metal bar 3, the connection is achieved by passing the screw 19 through the threaded hole 20. When the external wind force is strong or it is hit, the metal connecting plate 18 is prone to loosening. By detecting the contact resistance, it can be determined whether the connection between the metal connecting plate 18 and the metal bar 3 is loose.

[0025] Preferably, a temporary support mechanism is also included, which includes a third electric push rod 21 and a U-shaped support frame 22. The third electric push rod 21 is tilted on the side wall of the metal bar 3, and its output shaft is connected to the bottom surface of the U-shaped support frame 22. The metal connecting rod 17 is located above the moving path of the U-shaped support frame 22, and the main control unit 15 is electrically connected to the third electric push rod 21.

[0026] When the main control unit 15 determines that looseness has occurred, the third electric push rod 21 can drive the U-shaped support frame 22 to rise. During the rising process, the U-shaped support frame 22 can contact the bottom end of the metal connecting rod 17, thereby achieving temporary support for the metal connecting rod 17, buying a certain amount of time for maintenance personnel.

[0027] Preferably, the temporary support mechanism includes a pressure sensor 23, a pad 24 and a spring 25. The pressure sensor 23 is arranged on the bottom surface of the U-shaped support frame 22. The pad 24 is located in the U-shaped support frame 22 and above the pressure sensor 23. The spring 25 connects the bottom surface of the pad 24 and the pressure sensor 23. The main control unit 15 is electrically connected to the pressure sensor 23.

[0028] When the metal connecting plate 18 is not loose, after the U-shaped support frame 22 rises to a fixed position, the pad 24 will contact the metal connecting rod 17 and trigger the pressure sensor 23 through the spring 25. If the metal connecting plate 18 is loose, the metal connecting rod 17 will sag, and the U-shaped support frame 22 has not risen to the specified position, the pad 24 will first contact the bottom surface of the metal connecting rod 17, causing the pressure sensor 23 to be triggered. As the U-shaped support frame 22 rises, the data of the pressure sensor 23 will continue to change. The main control unit 15 can roughly judge the degree of sagging of the metal connecting rod 17 based on the pressure data collected by the pressure sensor 23, so as to decide whether to perform maintenance or directly replace it.

[0029] Preferably, the temporary support mechanism also includes a sleeve 26 and a moving rod 27. The sleeve 26 is arranged on the inner bottom surface of the U-shaped support frame 22. The pressure sensor 23 is located inside the sleeve 26. The bottom end of the moving rod 27 extends into the sleeve 26, and its top end is connected to the bottom surface of the pad 24. The spring 25 connects the bottom end of the moving rod 27 and the pressure sensor 23.

[0030] In order to ensure that the spring 25 can stably apply pressure to the pressure sensor 23, a sleeve 26 is provided on the outside of the pressure sensor 23. When the pad 24 contacts the bottom surface of the metal connecting rod 17, the spring 25 will be pushed and squeezed through the moving rod 27, and the sleeve 26 will limit the moving rod 27 to ensure that the U-shaped support frame 22 and the pad 24 always move in the vertical direction.

[0031] Preferably, the rotating mechanism includes a rotating motor 28, a gear 29 and a rack 30. The rotating motor 28 is embedded in the outer wall of the communication tower 1, and its output shaft is connected to the gear 29. The rack 30 is arranged on the bottom surface of the insulating ring 2 and is arranged circumferentially. The gear 29 is engaged with the rack 30, and the main control unit 15 is electrically connected to the rotating motor 28.

[0032] The rotating motor 28 can drive the gear 29 to rotate, and the gear 29 drives the insulating ring 2 to rotate through the rack 30, so that the metal bracket 5 at different positions can be moved to the bottom of the power box 8, so that the electrode head 11 can be connected to the conductive interface 6, while ensuring that the open and close current clamp 14 can be mounted on the corresponding metal connecting rod 17.

[0033] Preferably, a slider 31 is provided on the inner circumferential surface of the insulating ring 2 , an annular groove 32 is provided on the outer wall of the communication tower 1 , and the slider 31 is located in the annular groove 32 .

[0034] When the insulating ring 2 rotates, the slider 31 can move along the annular groove 32 to ensure stable rotation of the insulating ring 2.

[0035] Preferably, the connection detection mechanism also includes a transmitting tube 33 and a receiving tube 34, the transmitting tube 33 is arranged at intervals on the top surface of the insulating ring 2, and the receiving tube 34 is arranged on the bottom surface of the fixed ring 7 and is located above the rotation path of the transmitting tube 33, and the main control unit 15 is electrically connected to the transmitting tube 33 and the receiving tube 34 respectively.

[0036] In order to accurately locate the positions of the metal bracket 5 and the communication base station 4, a receiving tube 34 is set on the bottom surface of the fixed ring 7. At the same time, the number of transmitting tubes 33 arranged at intervals on the top surface of the insulating ring 2 is consistent with the number of communication base stations 4, and the infrared light emitted by different transmitting tubes 33 has different frequencies. During the rotation of the insulating ring 2, the number of the communication base station 4 and the metal bracket 5 located below is determined by detecting the infrared light of different frequencies received by the receiving tube 34, so as to facilitate the detection of different metal brackets 5.

[0037] Preferably, a wind direction sensor 35 is further included. The wind direction sensor 35 is arranged on the outer wall of the communication tower 1 , and the main control unit 15 is electrically connected to the wind direction sensor 35 .

[0038] The wind direction sensor 35 is used to detect the wind direction and wind force data around the communication tower 1. When it is determined that a metal bracket 5 is loose, the delivered metal bracket 5 and the communication base station 4 can be rotated to the leeward side to avoid further loosening of the metal bracket 5 due to excessive wind force.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
