Description

Technical Field

[0001] The present invention relates to the technical field of antennas, and specifically to an antenna that is convenient for installation and maintenance. Background Art

[0002] An antenna is a device used for transmitting and receiving electromagnetic waves, and is widely used in fields such as wireless communication, broadcasting, television, and radar.

[0003] When existing antennas are in use, it is difficult to adopt the method of loading a vibrator, making the diameter of the vibrator itself thinner and winding it into a spiral to increase the inductance of the vibrator itself and shorten the length of the vibrator, resulting in a lower radiation efficiency of the antenna and making it difficult to better receive and transmit signals; moreover, the environment may cause attenuation and interference to the signals, and it is difficult for the existing technology to improve the signal strength received by the antenna, improve the signal quality, and ensure the stable transmission of signals, resulting in easy interruption and fluctuation of the signals, and when some devices use signal boosters, it is difficult to install and disassemble the signal boosters, resulting in difficult later maintenance;

[0004] It also lies in that: when existing antennas are in use, it is difficult to reduce the impact on the antenna during the train wind and the vibration formed when the train passes by, and it is difficult for some devices to keep the original position of the airbag during the installation process to minimize the impact on the antenna, and the practicability is relatively single; when existing antennas are installed, it is difficult to reduce the installation connection points of the antenna, reduce the damage to the concrete wall surface and reduce the cost to improve the construction speed, and the practicability is relatively single;

[0005] Finally: when existing antennas are in use, it is difficult to adjust the angle of the radome to achieve lifting, resulting in the antenna being difficult to maintain the best working state under different environmental conditions, increasing the frequency and cost of equipment replacement, and resulting in lower signal reception sensitivity and signal-to-noise ratio.

[0038] The right end of the fourth electromagnetic block 53 is fixedly connected to an insulating rod 54. The right end of the insulating rod 54 is fixedly connected to a fixing block 55. There are two groups of fixing blocks 55, and the two groups of fixing blocks 55 are respectively arranged at the center of the left end and the center of the lower right end of the spring vibrator 56.

[0041] The working principle of an antenna that is easy to install and maintain based on Embodiment 1 is:

[0042] When using this device, first place this device in the working area, and then connect the device to an external power supply to provide the power required for the operation of this device.

[0043] When it is necessary to wind the spring vibrator 56 into a spiral, the twelve groups of third electromagnetic blocks 52 in the two mounting rods 51 are driven to work step by step through an external current output device, so that the two groups of fourth electromagnetic blocks 53 make relative movements under the magnetic influence of the twelve groups of third electromagnetic blocks 52, so that the distance between the two groups of fourth electromagnetic blocks 53 gradually increases.

[0044] Embodiment 2:

The electromagnetic groove 67 is composed of a chute provided at the right end of the cooperating rod 66 and an electromagnetic block fixedly connected inside the chute. The control switch 611 is electrically connected to the electromagnetic block inside the electromagnetic groove 67.

[0049] In this embodiment:

[0050] When the signal booster 610 needs to be installed, the staff drives the signal booster 610 to move from right to left. The signal booster 610 drives the insertion rod 68 to move leftward, so that the insertion rod 68 is inserted into the electromagnetic slot 67. Through the extension movement of the second telescopic rod 69, the second telescopic rod 69 is engaged with the slot of the insertion rod 68, and the insertion rod 68 is installed once, thereby installing the signal booster 610 once. Then, the micro motor 62 is started. The micro motor 62 drives the swing block 63 to swing leftward. The swing block 63 drives the cooperation rod 66 to move leftward in the limit block 65 through the contact with the top groove of the cooperation rod 66. The cooperation rod 66 drives the signal booster 610 to move leftward through the engagement of the second telescopic rod 69 with the slot of the insertion rod 68. At the same time as the cooperation rod 66 moves leftward, it synchronously presses the control switch 611, so that the control switch 611 controls the electromagnetic block in the electromagnetic slot 67 to work, so that the electromagnetic block in the electromagnetic slot 67 magnetically adsorbs the insertion rod 68, and the insertion rod 68 is installed for the second time, and then the signal booster 610 is installed for the second time, realizing the installation and disassembly of the signal booster 610 for later maintenance.

[0051] Embodiment 3:

[0056] The staff activates the solenoid valve 25 in advance, then connects the delivery pipe 24 to the external gas delivery tank, and conveys the external gas through the delivery pipe 24 to the airbag 21 to inflate the airbag 21. Then, the electric spring 22 is powered on through an external power supply device. When there is vibration formed by the train wind and the passing of the train, the airbag 21 deforms, and the electric spring 22 makes a stretching movement along with the deformation of the airbag 21 and generates a stress field around it. This stress field will affect the resistance value of the resistance strain gauge 23. Then, the resistance strain element inside the resistance strain gauge 23 deforms under the action of stress, enabling the user to calculate the length change of the electric spring 22 through the resistance value of the resistance strain gauge 23, and indirectly calculate the deformation state of the airbag 21 through the length change of the electric spring 22, thereby indirectly monitoring the change in the air pressure received by the airbag 21, facilitating the staff to adjust the inflation amount in a timely manner later, keeping the airbag 21 in the best inflated state all the time, thus ensuring the best shock absorption effect, and providing additional elasticity through the electric spring 22 to maintain the original position of the airbag 21 during installation and minimize the impact on the tunnel antenna to the greatest extent.
