TECHNICAL FIELD

[0001] The utility model relates to broadcast antenna installation technical field, concretely is a broadcast antenna installation structure. BACKGROUND

[0002] Broadcast antenna is a transmission medium that broadcasts sound and image programs to a wide area through radio waves or through wires, collectively known as broadcasting. If only sound is broadcast, it is called sound broadcasting. A broadcast antenna installation structure is required when installing a broadcast antenna. For example, the antenna connecting device with the application number "202222222306.4" includes a positioning cylinder, a mounting base fixedly connected to the bottom of the positioning cylinder, and a plug column movably inserted into the inner wall of the positioning cylinder.

[0003] However, although it can achieve higher disassembly efficiency, since the broadcast antenna is usually installed in an outdoor environment and is installed on a high tower, it is subjected to wind for a long time. When the wind is strong, the broadcast antenna without a reinforcing device of the traditional technology is prone to swinging back and forth with the wind, affecting the stability of the fixed connection. UTILITY MODEL CONTENT

[0004] The utility model aims at solving the problem of the broadcast antenna without a reinforcing device of the traditional technology, which causes the unsecured end of the broadcast antenna to swing back and forth with the wind, affecting the stability of the fixed connection, and proposes a broadcast antenna installation structure.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme:

[0006] A broadcast antenna installation structure is designed, which includes a stand and a sleeve ring. The outer wall of the stand is fixedly connected with the sleeve ring. The outer wall of one side of the sleeve ring is fixedly connected with an end plate. The front end of the end plate is fixedly connected with the beam part of the broadcast antenna. A stretching assembly is installed at the center of the other side of the sleeve ring. The four corners of the other side of the sleeve ring are fixedly connected with the shell through bolts.

[0007] Preferably, the stretching assembly includes rollers, brackets, servo motors, and winding rollers. The rotating parts of multiple rollers are rotatably connected with the brackets through bearings. The ends of the brackets are fixedly connected with the left side of the beam part of the broadcast antenna. The outer wall of the roller is wound with a rope. The end of one side of the rope is wound around the outer wall of a lifting ring. The inside of the lifting ring is on the right side of the beam part of the broadcast antenna. The rotating parts of multiple winding rollers are rotatably connected with the sleeve ring through bearing seats. The end of the rotating part of one side of the winding roller is fixedly connected with the output shaft of the servo motor. Gears are fixedly connected above the rotating parts of the winding rollers. Pressure plates are arranged on the outer wall of the rotating shaft of the gears. The outer wall center of the pressure plate is fixedly connected with the output shaft of the self-locking air cylinder.

[0008] Preferably, the servo motor is fixedly connected below the outer wall of the sleeve ring, and the end of the main body of the self-locking cylinder is fixedly connected with the sleeve ring.

[0009] Preferably, the beam part of the broadcast antenna is provided with a plurality of supporting rods fixedly connected with the outer wall.

[0010] Preferably, the end of each supporting rod is fixedly connected with a sleeve.

[0011] Preferably, the inside of the sleeve is matched with the rope.

[0012] The broadcast antenna mounting structure has the beneficial effects that:

[0013] The servo motor, the self-locking cylinder, the winding roller, the gear, the rope, the pressing plate and the broadcast antenna are matched, so that when the wind is large, the wind power warning or the wind power detection instrument can be used for detection, and signals are transmitted to the servo motor and the self-locking cylinder, the output shaft of the servo motor drives the two winding rollers to rotate synchronously and reversely through the gear, the rope is further tightened (in a relaxed state in daily life), the side of the broadcast antenna which is not fixedly connected is limited in position by the rope, and after being tightened, the self-locking cylinder drives the pressing plate to move, the rubber pad on the inner wall of the pressing plate is pressed on the outer wall of the rotating shaft of the gear to limit the rotation of the gear, and the rotation of the winding roller is further limited, so that the side of the broadcast antenna which is not fixedly connected can be effectively limited in position in strong wind, and the problem that the side of the broadcast antenna which is not fixedly connected is easily swung back and forth with the wind to affect the stability of the fixed connection in the prior art is avoided.

[0024] Working principle:

[0025] When the broadcast antenna mounting structure needs to be used, first, the user can pre-weld the collar 2 to the outer wall of the stand 1, then install the end plate 4 connected with the broadcast antenna 6 on one side of the collar 2, and install it through bolts, then straighten the two side ropes 302 and pass them through the sleeve 5 and the roller 301 in turn and finally fix them to the outer wall of the winding roller 309, and ensure that they are straightened, thus completing the installation process of the broadcast antenna 6. In specific use, the signal line and the power line provide signals and power for the broadcast antenna 6, so that the broadcast antenna 6 transmits radio signals for broadcasting. Since the broadcast antenna 6 is usually installed in an outdoor environment and is arranged to be installed on a high tower, the broadcast antenna 6 is in a windy environment for a long time. When the wind is strong, the broadcast antenna 6 of the traditional technology has no reinforcing device, so that the end of the broadcast antenna 6 (usually only one side connected to fix the broadcast antenna 6, the end refers to the side not connected) is easy to sway back and forth with the wind, which affects the stability of the fixed connection. Therefore, the stretching assembly 3 is designed. When the wind is strong, the wind warning or wind detection instrument can be detected, and the signal is transmitted to the servo motor 306 and the self-locking cylinder 308. The output shaft of the servo motor 306 can drive the two side winding rollers 309 to rotate synchronously and reversely through the gear 305, so as to further tighten the rope 302 (which is usually in a relaxed state), so that the side not connected to the broadcast antenna 6 is limited in position by the way of pulling the rope. After tightening, the self-locking cylinder 308 drives the pressing plate 307 to move, so that the rubber pad on the inner wall of the pressing plate 307 is pressed on the outer wall of the rotating shaft of the gear 305 to limit the rotation, which further realizes the rotation limitation of the winding roller 309. In this way, the side not connected to the broadcast antenna 6 can be effectively limited in strong wind, effectively avoiding the problem that the end not connected to the broadcast antenna 6 of the broadcast antenna 6 of the traditional technology is easy to sway back and forth with the wind, which affects the stability of the fixed connection.

[0026] When the strong wind condition is removed, the output shaft of the self-locking cylinder 308 controls the movement of the pressing plate 307, removes the rotation limitation of the winding roller 309, and reverses the servo motor 306 to release the tension of the rope 302. The reason why the straightening state of the rope 302 is not maintained all the time is that the swing amplitude of the broadcast antenna 6 caused by the wind under normal conditions is small and will not affect the fixed connection of the broadcast antenna 6. If the straightening state of the rope 302 is maintained, the position locking function of the equipment will be worn out under frequent vibration, which will not work effectively when the tension is released in the whole strong wind weather. Therefore, it is only necessary to further reinforce the broadcast antenna 6 when the detected wind is strong.
