[0003] In the related art, in order to facilitate maintenance work such as debugging or repairing the antenna, an inspection door is opened on the antenna cover. When the antenna needs maintenance, the inspection door is opened to enter the antenna cover for maintenance.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: because multiple antennas are installed in the antenna cover, a maintenance door will greatly limit the operating space for maintenance, and the staff can only operate from a fixed angle, thereby reducing the convenience of maintaining the antenna. Summary of the invention

[0005] In order to improve the convenience of maintaining the antenna, the present application provides a cluster antenna.

[0006] The present application provides a cluster antenna, which adopts the following technical solution:

[0007] A cluster antenna comprises a base, an antenna cover arranged on the base, and an antenna body arranged in the antenna cover, wherein the antenna cover is provided with a maintenance device connected to the base, and the maintenance device comprises:

[0008] An annular door, the two ends of which are rotatably arranged on the opposite end of the antenna cover and the base;

[0009] An inspection door, which is arranged on the annular door and is used by workers to enter and exit the antenna housing;

[0010] A fixing assembly is arranged on the base and is used for positioning the annular door.

[0011] By adopting the above technical solution, the fixing component is opened, and then the annular door is rotated to drive the inspection door to rotate together. After it is rotated to a suitable position, the staff can open the inspection door and enter the antenna cover to maintain the antenna body. Therefore, the staff can choose a suitable angle to enter the antenna cover according to needs, thereby improving the convenience of maintaining the antenna; at the same time, when installing the antenna body, the antenna cover can also be entered through the inspection door, thereby improving the convenience of the antenna installation process.

[0012] Optionally, the fixing component includes:

[0013] An electromagnet ring, the electromagnet ring being arranged on a base and having a plurality of locking grooves arranged in an array around the axis of the antenna cover;

[0014] A locking column, which is slidably disposed on the annular door and is inserted into the locking groove under the action of the electromagnet ring;

[0015] A locking spring, wherein both ends of the locking spring are respectively connected to the annular door and the locking column. After the electromagnet ring is powered off, the locking column is separated from the locking groove under the action of the locking spring;

[0016] A control switch is arranged on the base and is used to control the electromagnet ring to be powered on or off.

[0017] By adopting the above technical scheme, the control switch controls the electromagnet ring to cut off the power, and the locking column is disengaged from the locking groove under the action of the locking spring, and then the annular door can be rotated. After the rotation is completed, the control switch controls the electromagnet ring to be energized, and the locking column is adsorbed by the electromagnet ring and plugged into the electromagnet ring, so as to position the annular door, thereby realizing the rotation and positioning of the annular door; if the locking column is adsorbed on the surface of the electromagnet ring, the annular door continues to be rotated, so that the locking column is adsorbed and plugged into the locking groove, there is no need to manually find the positioning position, which improves the convenience of using the annular door, and when the annular door is rotated, the locking column is disengaged from the electromagnet ring, reducing the damage to the electromagnet ring when the annular door is rotated.

[0018] Optionally, the control switch is electrically connected to the antenna body, and the control switch controls the antenna body and the electromagnet ring to be powered on or off simultaneously. The locking column is provided with a guide angle for facilitating insertion into the locking groove.

[0019] By adopting the above technical solution, when the antenna body needs to be inspected and repaired, the control switch controls the electromagnet ring and the antenna body to cut off the power at the same time, so that the annular door can rotate freely, and then the staff enters the antenna cover. Therefore, when the staff enters the antenna cover, the antenna body must be cut off first, which reduces the probability that the staff forgets to cut off the power before maintaining the antenna body, thereby reducing the probability that the antenna body is energized and causes damage to the staff, and improving the safety of the staff at work; the guide angle is provided on the locking column when it is inserted into the locking groove for guidance, which improves the convenience of positioning the annular door.

[0025] At the same time, the connecting device is located outside the antenna cover, which reduces the probability of occupying the space inside the antenna cover, reduces the probability of the connecting device interfering with the antenna body inside the antenna cover, and improves the efficiency of the antenna body receiving signals. Moreover, when the connecting rod interferes with the detection door, the connecting rod can be disassembled and replaced to other positions to connect the antenna cover and the base, thereby further increasing the angle for the staff to enter the antenna cover, and reducing the probability of the connecting device being located inside to block the staff from entering the antenna cover, thereby further improving the convenience of maintaining the antenna.

After the replacement is completed, one end of the annular door is first slidably installed on the slide located on the base, and then the antenna cover and the base are fixedly connected together, so that the other end of the annular door is slidably installed on the slide located on the antenna cover, thereby improving the convenience when installing the slide and the annular door, and also improving the convenience of replacing the electromagnet ring.

[0030] Optionally, a mounting groove is provided on the side wall on the opposite side of the two slideways, and a sealing ring is clamped and installed on the mounting groove to abut against the outer side wall of the annular door.

[0031] By adopting the above technical solution, the sealing ring seals the gap between the annular door and the slide, reducing the probability of rainwater entering the antenna cover and causing damage to the antenna body, thereby increasing the life of the antenna body; at the same time, the sealing ring is snap-fitted and installed in the mounting groove to facilitate replacement of the sealing ring, thereby improving the sealing effect of the sealing ring and further increasing the life of the antenna body.

[0032] Optionally, the first connecting ring and the second connecting ring are respectively slidably mounted on the antenna cover and the base and can be removed from the antenna cover and the base, and the first connecting ring and the second connecting ring are both threadedly connected with fixing screws that are respectively pressed against the antenna cover and the base.

[0033] By adopting the above technical solution, the fixing screw is turned away from the antenna cover, and then the position of the first connecting ring is moved.

[0034] At the same time, the distance between the antenna cover and the base can be increased, and then the annular door can be replaced. After the replacement is completed, the antenna cover and the base are adjusted to move back to their original positions, so that the annular door can be replaced without completely disassembling the antenna cover, thereby improving the convenience of replacing the annular door.
