Description

Technical Field

[0001] The utility model relates to the field of receiving antennas, in particular to a frequency modulation broadcasting and television receiving antenna. Background Art

[0002] In the cable TV system, the task of the antenna is to receive the open-circuit TV signal or satellite TV signal in the air and send it to the system for processing, transmission and distribution. The antenna that receives the open-circuit TV signal in the VHF and UHF bands is called a TV receiving antenna. The TV receiving antenna is an important part of wireless TV signal reception and is the gateway for radio waves to enter the cable TV system. There are two types of antennas: passive antennas and active antennas. Active antennas can enable the antenna system to achieve high gain and high signal-to-noise ratio reception.

[0003] According to the published patent 202322686960.5, an FM radio and television receiving antenna with a visual prompt function includes a mounting seat and an adjusting mechanism. The adjusting mechanism includes a fixing cylinder, which is fixedly connected to the top of the mounting seat. A telescopic connecting rod is rotatably embedded between the top of the fixing cylinder and the top of the mounting seat. A receiving antenna body is fixedly connected to the top of the telescopic connecting rod. The mounting seat provides stable support for the adjusting mechanism and the receiving antenna body. An annular warning light is arranged on the receiving antenna body to facilitate warning at night to avoid damage to the FM radio and television receiving antenna due to accidental contact, thereby improving its safety in use. The fixing cylinder can be used to protect the key driving part at the bottom of the telescopic connecting rod, thereby improving its safety in use. The telescopic connecting rod can be used to conveniently drive the receiving antenna body to adjust its height. At the same time, the telescopic connecting rod rotates to conveniently drive the receiving antenna body to rotate, thereby improving its safety in use. Effect of use: In the process of realizing the utility model, the inventor found that at least the following problems in the prior art have not been solved: although the mounting seat provides stable support for the adjustment mechanism and the receiving antenna body, and a ring warning light is set on the receiving antenna body to facilitate warning at night, avoid accidental contact and damage to the FM radio and television receiving antenna, and improve its safety in use, during use, the traditional FM radio and television receiving antenna often has a certain distance between the position of the receiving antenna and the position of the TV, so when adjusting the position of the receiving antenna and aligning it with a position with a stronger signal, the adjuster is often unclear about the specific signal strength of the TV during adjustment, resulting in poor signal adjustment effect, and the antenna cover is exposed to the outside during use, resulting in a large amount of dust particles and impurities easily adhering to the surface of the antenna cover, which easily affects the effect of signal reception. For this reason, it is necessary to design a new technical solution to solve it. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, meet actual needs, and provide an FM radio and television receiving antenna to solve the problem that the current traditional FM radio and television receiving antenna often has a certain distance between the position of the receiving antenna and the position of the television. Therefore, when adjusting the position of the receiving antenna to align it with a position with a stronger signal, the adjuster is often unclear about the specific signal strength of the TV during adjustment, resulting in a poor signal adjustment effect. Moreover, during use, the antenna cover is exposed to the outside, resulting in a large amount of dust particles and impurities easily adhering to the surface of the antenna cover, which easily affects the technical problem of the effect of signal reception.

[0005] In order to achieve the purpose of the utility model, the technical solution adopted by the utility model is: designing an FM radio and television receiving antenna, including a device base, and also including:

[0006] An antenna cover is arranged on the top of the device base;

[0007] A signal monitoring mechanism is installed at the bottom of one side of the antenna cover, and the signal monitoring mechanism includes a signal strength detection sensor, and the signal strength detection sensor is installed at the bottom of one side of the antenna cover;

[0008] A monitoring host is installed in the middle of the front end of the device housing, and the monitoring host is connected to the signal strength detection sensor signal.

[0009] Preferably, connecting rods are fixed to both upper and lower ends of one side of the antenna cover, a device shell is fixed to one side of the connecting rod, a groove is opened on one side of the device shell, a first motor is installed on one side inside the groove, a first motor shaft is connected to one side of the first motor, and a rotating column is fixed to the end of the first motor shaft away from the first motor through the antenna cover.

[0010] Preferably, a plurality of connecting strips are fixed to the outer wall of the rotating column, and a cleaning brush is fixed to one side of the plurality of connecting strips.

[0011] Preferably, a plurality of mounting grooves are provided on the outer wall of the device base, and infrared sensors are installed on one side of the inner walls of the plurality of mounting grooves, and a protective net is installed on the other side of the inner wall of the mounting grooves.

[0012] Preferably, a circular groove is provided on the top of the device base, a second motor is installed inside the circular groove, a second motor shaft is connected to the top of the second motor, a rotating rod is fixed on the top of the second motor shaft, and a device housing is fixed on the top of the rotating rod.

[0013] Preferably, annular light strips are installed at both upper and lower ends of the outer wall of the device base.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The utility model combines an antenna cover, a signal strength detection sensor and a monitoring host, and can set a signal strength detection sensor on the surface of the antenna cover. When the antenna cover is rotated to adjust the signal strength, the signal strength of different positions can be detected by the signal strength detection sensor, and the current signal strength can be displayed on the monitoring host, so that the staff can easily select the position with a stronger signal. At the same time, since a monitoring host is provided, the radio and television signals received by the antenna can be displayed on the monitoring host, so that the adjuster can directly view whether the current TV display at the adjusted position is clear during the adjustment process, which solves the problem of traditional FM radio and television receiving antennas, where there is often a certain distance between the position of the receiving antenna and the position of the TV. Therefore, when adjusting the position of the receiving antenna to align with the position with a stronger signal, the adjuster is often not clear about the specific signal strength of the TV during adjustment, resulting in poor signal adjustment effect.

[0016] 2. The utility model combines the first motor, the connecting strips and the cleaning brush. When a large amount of dust particles and impurities are attached to the surface of the antenna cover, the first motor can be turned on to drive the multiple connecting strips. The multiple connecting strips will drive the cleaning brush to clean the dust particles and impurities on the surface of the antenna cover, thereby solving the technical problem that a large amount of dust particles and impurities are easily attached to the surface of the antenna cover due to being exposed to the outside during use, which easily affects the effect of signal reception.

[0017] 3. The utility model can connect the infrared sensor and the annular light strip to the monitoring host through the combination of infrared sensors, mounting grooves and annular light strips. When the infrared rays of multiple infrared sensors pass through the mesh holes, animals in different positions can be sensed. After the infrared sensor senses, it will send a signal to the monitoring host, and the monitoring host will turn on the annular light strip to warn the surrounding animals.

DETAILED DESCRIPTION

[0022] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0023] Embodiment 1: An FM broadcast television receiving antenna, see Figures 1 to 3 , including a device base 1, and also including: an antenna cover 205, which is arranged on the top of the device base 1; a signal monitoring mechanism, which is installed at the bottom of one side of the antenna cover 205, and the signal monitoring mechanism includes a signal strength detection sensor 206, and the signal strength detection sensor 206 is installed at the bottom of one side of the antenna cover 205; a monitoring host 207 is installed in the middle of the front end of the device shell 203, and the monitoring host 207 is connected to the signal strength detection sensor 206 by signal. The signal strength detection sensor 206 is arranged on the surface of the antenna cover 205. In the process of rotating the antenna cover 205 to adjust the signal strength, the signal strength of different positions can be detected by the signal strength detection sensor 206. The present signal strength can be measured and displayed on the monitoring host 207, so that the staff can conveniently select the position with stronger signal. At the same time, since the monitoring host 207 is provided, the broadcasting and television signals received by the antenna can be displayed on the monitoring host 207, so that the adjuster can directly check whether the current television display at the adjustment position is clear during the adjustment process. This solves the problem that the position of the traditional FM broadcasting and television receiving antenna is often at a certain distance from the position of the television. Therefore, when adjusting the position of the receiving antenna to align with the position with stronger signal, the adjuster is often not clear about the specific signal strength of the television during adjustment, resulting in poor signal adjustment effect.

A groove 302 is opened on one side of the device shell 203, and a first motor 303 is installed on one side of the groove 302. A first motor shaft 304 is connected to one side of the first motor 303, and an end of the first motor shaft 304 away from the first motor 303 passes through the antenna cover 205 and is fixed with a rotating column 204. When it is necessary to clean the surface of the antenna cover 205, the first motor 303 can be turned on, the first motor 303 drives the first motor shaft 304, the first motor shaft 304 drives the rotating column 204, and the rotating column 204 drives multiple connecting strips 3. The multiple connecting strips 3 will drive the cleaning brush 301 to rotate on the surface of the antenna cover 205 to clean the dust particles and impurities on the surface of the antenna cover 205, thereby solving the technical problem that a large amount of dust particles and impurities are easily attached to the surface of the antenna cover 205 due to being exposed to the outside during use, which easily affects the effect of signal reception.

[0025] For further information, see Figure 1 A plurality of connecting strips 3 are fixed to the outer wall of the rotating column 204 , and a cleaning brush 301 is fixed to one side of the plurality of connecting strips 3 .

After the infrared sensor and the annular light strip 208 are connected to the monitoring host 207, when the infrared rays of the plurality of infrared sensors pass through the mesh, the animals at different positions can be sensed. After the infrared sensor senses, a signal will be sent to the monitoring host 207, and the monitoring host 207 will turn on the annular light strip 208 to warn the surrounding animals.

[0027] It is worth noting that see Figure 1 A circular groove 212 is provided on the top of the device base 1, and a second motor 2 is installed inside the circular groove 212.

[0028] It is worth mentioning that see Figure 1 , annular light strips 208 are installed at both upper and lower ends of the outer wall of the device base 1.

[0029] When using an FM radio and television receiving antenna, a signal strength detection sensor 206 is arranged on the surface of the antenna cover 205. In the process of rotating the antenna cover 205 to adjust the signal strength, the signal strength of different positions can be detected by the signal strength detection sensor 206, and the current signal strength can be displayed on the monitoring host 207, so that the staff can conveniently select the position with a stronger signal. At the same time, since the monitoring host 207 is arranged, the radio and television signals received by the antenna can be displayed on the monitoring host 207, so that the adjuster can directly view whether the current TV display at the adjustment position is clear during the adjustment process, and when it is necessary to adjust the surface of the antenna cover 205 When cleaning, the first motor 303 can be turned on, the first motor 303 drives the first motor shaft 304, the first motor shaft 304 drives the rotating column 204, the rotating column 204 drives multiple connecting strips 3, and the multiple connecting strips 3 will drive the cleaning brush 301 to rotate on the surface of the antenna cover 205 to clean the dust particles and impurities on the surface of the antenna cover 205. After the infrared sensor and the annular light strip 208 are connected to the monitoring host 207, when the infrared rays of the multiple infrared sensors pass through the mesh, they can sense animals in different positions. After the infrared sensor senses, it will send a signal to the monitoring host 207, and the monitoring host 207 will turn on the annular light strip 208 to warn the surrounding animals.
