Description

Technical Field

[0001] This utility model relates to the field of signal enhancement technology, and in particular to a broadcast television transmission signal enhancement device. Background Technology

[0002] Broadcast television is a news dissemination tool that transmits sound, images, and video through radio waves or wires. It can play images and sound. Broadcast television signal enhancement mainly aims to improve signal quality, expand coverage, optimize user experience, and promote industry development. Generally, fiber optic amplifiers are used to enhance the strength of television signals.

[0003] To ensure the stability of fiber optic amplifiers during placement, they are usually installed against a wall or in a corner. In this case, the bottom of the fiber optic amplifier is in close contact with the placement area, and its back is also in close contact with the wall. As a result, heat cannot be effectively dissipated from the bottom and back, which can cause the local temperature of the fiber optic amplifier to become too high. This may accelerate the aging of internal components, reduce performance, or even cause failure. To address this issue, we propose a broadcast television transmission signal enhancement device. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a broadcast television transmission signal enhancement device.

Four sets of columns are symmetrically distributed at the bottom of the optical fiber amplifier, and the bottom of the four sets of columns are connected to a support plate. A rectangular groove is opened on the back of the support plate. An interface is opened on the back of the optical fiber amplifier, and a plug is inserted into the interface. The other end of the plug is connected to a power cord.

[0007] Preferably, the bottom end of the fiber optic amplifier is symmetrically provided with slots, and each slot is fitted with a connecting rod, the bottom end of which is fixedly connected to the upper side of the column.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-5 A broadcast television transmission signal enhancement device includes an optical fiber amplifier 1. Four sets of uprights 4 are symmetrically distributed at the bottom of the optical fiber amplifier 1, and the bottom ends of the four sets of uprights 4 are connected to a support plate 5. The four sets of uprights 4 provide support for the optical fiber amplifier 1, ensuring a certain gap between the bottom of the optical fiber amplifier 1 and the support plate 5 for proper heat dissipation. A rectangular groove 6 is provided on the back of the support plate 5. Since the support plate 5 is designed in an L-shape, and there is also a gap between the back of the optical fiber amplifier 1 and the support plate 5, proper heat dissipation on the back of the optical fiber amplifier 1 is ensured. Two sets of mounting ears on the front of the optical fiber amplifier 1 ensure proper heat dissipation on the sides of the optical fiber amplifier 1. An interface is provided on the back of the optical fiber amplifier 1, and a plug 2 is inserted into the interface. The other end of the plug 2 is connected to a power cord 3.

[0024] Furthermore, refer to Figure 3 It can be seen that the bottom of the fiber optic amplifier 1 is symmetrically provided with slots, and each slot is fitted with a connecting rod 7. The bottom of the connecting rod 7 is fixedly connected to the upper side of the column 4. During use, the fiber optic amplifier 1 and the upright plate 5 can be disassembled and assembled through the connecting rod 7 and the slots, thereby reducing the footprint of the device during transportation.

[0025] Furthermore, refer to Figure 3 It can be seen that a rubber ring 8 is connected to the outside of the connecting rod 7. The outer wall of the rubber ring 8 and the inner wall of the groove are tightly fitted. During use, the rubber ring 8, which is made of rubber, can effectively ensure the tightness of the connecting rod 7 inserted into the groove.

[0026] Furthermore, refer to Figure 4 and Figure 5It can be seen that there are two sets of moving strips 9 distributed inside the rectangular groove 6, and the sides of the moving strips 9 are connected to the sliding block 11 by the connecting spring 14. The other end of the sliding block 11 is connected to the insertion rod 10. The inner wall of the rectangular groove 6 is provided with slots that are adapted to the insertion rod 10 at equal intervals. In use, the distance between the two sets of moving strips 9 can be adjusted by the cooperation of the sliding block 11 and the insertion rod 10 and the opening of multiple sets of slots. When the two sets of moving strips 9 are adjusted to a state where they are far apart, the operator can pull the plug 2 out from the interface on the back of the fiber optic amplifier 1. When the two sets of moving strips 9 are adjusted to a state where they are close together, the plug 2 inserted into the interface on the back of the fiber optic amplifier 1 can be limited to prevent the plug 2 from being pulled out of the interface by the pulling force.

[0027] Furthermore, refer to Figure 5 It can be seen that there are two sets of insertion rods 10 distributed on the outer side of the moving strip 9, and the two sets of insertion rods 10 are symmetrically distributed about the central axis of the moving strip 9. The positioning effect of the moving strip 9 can be achieved by setting the two sets of insertion rods 10.

[0028] Furthermore, refer to Figure 5 It can be seen that the movable bar 9 is set as a T-shaped structure, and the side of the movable bar 9 is connected to the fixed rod 12. The sliding block 11 has a hole that matches the fixed rod 12. Through the cooperation of the fixed rod 12 and the hole, the sliding block 11 and the insertion rod 10 can be guided laterally.

[0029] Furthermore, refer to Figure 4 and Figure 5 It can be seen that the side of the moving strips 9 that are close to each other is glued with a rubber plate 13, and the outer surface of the rubber plate 13 is provided with anti-slip texture. Through the cooperation of the rubber plate 13 and the anti-slip texture, the clamping effect of the two sets of moving strips 9 on the power cord 3 can be guaranteed.

[0030] Working Principle: When using this utility model, the operator can first insert the plug 2 into the interface on the back of the fiber optic amplifier 1, and then pull the two sets of sliding blocks 11 distributed on the side of the moving strip 9, so that the insertion rod 10 connected to the side of the moving strip 9 is pulled out from the slot opened in the inner wall of the rectangular groove 6. At this time, the operator can vertically move the position of the moving strip 9 so that the rubber plate 13 connected to its side abuts against the outer wall of the power cord 3. Then the operator can pull the other two sets of sliding blocks 11 so that the two sets of moving strips 9 clamp and fix the power cord 3. Then the operator can place this device in a suitable position. Therefore, during the operation of the fiber optic amplifier 1, due to the setting of the upright plate 5, since there is a gap between the upright plate 5 and the back of the fiber optic amplifier 1, and a gap between the bottom of the fiber optic amplifier 1 and the upright plate 5, the normal heat dissipation of the fiber optic amplifier 1 can be effectively guaranteed. The above is the complete working principle of this utility model.
