Description

Technical Field

[0001] The utility model relates to the technical field of broadcast signal detection, in particular to a signal detection tool for broadcast and television transmission. Background Art

[0002] Radio and television are news dissemination tools that transmit sound, images, and videos through radio waves or wires. Broadcasting only sounds is called audio broadcasting; broadcasting images and sounds is called television broadcasting. After the broadcast battery transmits the signal through the transmitter, the terminal uses a signal receiving device (antenna) to receive the transmitted signal. In order to ensure the signal reception effect, a signal reception detection tool is generally used to detect the signal strength.

[0003] The patent with publication number CN215927642U proposes a signal detection tool for radio and television transmission. By setting an impeller, it can use wind force to drive the impeller to rotate, and the impeller then drives the generator to generate electricity, thereby realizing the use of wireless power supply in the wild. Secondly, by setting the connection contact plate and the connection contact point, the impeller can be limited in windy weather to avoid damage to the impeller. However, wind power generation is not stable enough, and the antenna has no protective structure when used in windy weather and is easily damaged. In addition, the device can only be fixed in one place for use, which is inconvenient to move, and it cannot detect signals in different locations, so it needs further improvement.

[0020] As shown in Figures 1 to 3, a signal detection tool for broadcasting and television transmission is disclosed, comprising a base plate 1, a box body 2 is fixed on the upper surface of the base plate 1, and the top of the box body 2 is open, a top cover 3 is provided on the top of the box body 2, a vertical pipe 4 is fixed in the middle of the lower surface of the top cover 3, a lifting component for driving the vertical pipe 4 to move is provided in the middle of the base plate 1 and inside the box body 2, an antenna 5 is fixed on the top surface of the vertical pipe 4, a receiving terminal 10 electrically connected to the antenna 5 is installed on the inner bottom wall of the box body 2, a solar panel 11, a rain sensor 13 and a wind speed sensor 14 are fixed on the upper surface of the top cover 3, a controller 15 is installed on the lower surface of the top cover 3, and a moving component is installed on the lower surface of the base plate 1.

[0021] like Figure 2 As shown, the lifting assembly includes a servo motor 7 fixed to the lower surface of the base plate 1, a screw rod 6 is fixed to the top driving end of the servo motor 7, the top end of the screw rod 6 extends to the inside of the box body 2, the screw rod 6 passes through the inside of the vertical pipe 4 and is threadedly connected to the vertical pipe 4, a side rod 8 is fixed to the side wall of the bottom end of the vertical pipe 4, a slide groove 9 is opened on the inner side wall of the box body 2, and the side rod 8 is slidably connected to the slide groove 9 at one end away from the vertical pipe 4, and the servo motor 7, the rain sensor 13 and the wind speed sensor 14 are all electrically connected to the controller 15.

[0022] The rain sensor 13 and the wind speed sensor 14 can monitor the rain weather or wind speed of the tool in the field environment. When it rains or the wind speed is too high, the controller 15 can control the servo motor 7 to rotate. After the servo motor 7 drives the screw rod 6 to rotate, the screw rod 6 will drive the vertical pipe 4 to move downward along the slide groove 9, so that the top cover 3 covers the top of the box body 2. At this time, the antenna 5 descends and retracts into the box body 2, which can protect the antenna 5.

[0023] like Figure 2 As shown in FIG. 3 , an annular groove 31 is formed on the side of the lower surface of the top cover 3 , and a sealing strip 32 is clamped inside the annular groove 31 .

[0024] When the top cover 3 is closed on the top of the box body 2 , the sealing strip 32 can increase the sealing between the box body 2 and the top cover 3 .

[0025] As shown in Figures 1 and 2, a push handle 16 is fixed to one side of the upper surface of the base plate 1. The moving assembly includes two front wheels 18, two rear wheels 17 and a drive motor 19 fixed to the lower surface of the base plate 1. The drive motor 19 is located between the two front wheels 18, and the output end of the drive motor 19 is fixedly connected to the two front wheels 18.

[0030] Working principle: After the device is moved to the specified position, the servo motor 7 is started to drive the screw rod 6 to rotate, and the screw rod 6 drives the vertical pipe 4 to rise, so that the antenna 5 rises from the inside of the box 2. The antenna 5 and the receiving terminal 10 can be used to detect radio and television transmission signals. When the rain sensor 13 and the wind speed sensor 14 detect rain or too strong wind, the controller 15 will control the servo motor 7 to reverse, thereby driving the vertical pipe 4 to descend, so that the antenna 5 is retracted into the box 2, and the top cover 3 is closed on the top of the box 2, thereby providing more effective protection for the antenna 5.
