Description

Technical Field

[0001] This invention relates to a signal receiving device for broadcasting and television engineering, and more particularly to a signal receiving device for broadcasting and television engineering applied in the field of signal receiving devices. Background Technology

[0002] Signal receiving equipment for broadcast television engineering is a crucial component of modern communication technology, responsible for receiving broadcast and television signals from the air or via cable networks. With the development of digital technology, these devices have evolved from traditional analog receivers to digital receivers, capable of handling high-definition and ultra-high-definition video signals and multi-channel audio signals. Background technologies encompass multiple aspects, including antenna design, signal amplification, filtering, demodulation, decoding, and signal processing. To adapt to different transmission standards, such as DVB-T, ATSC, and ISDB-T, receiving equipment requires high flexibility and compatibility. Furthermore, with the convergence of internet technology, IPTV and network television receiving equipment have gradually become an important part of broadcast television engineering, receiving streaming media data through network protocols to provide users with a richer and more personalized viewing experience.

[0003] Chinese patent CN115514378B discloses a broadcast signal receiving device. The invention includes a signal receiving dish, a signal receiver, a disassembly mechanism, an angle adjustment mechanism, a lifting mechanism, and a support mechanism. When the signal receiving dish needs to be installed, the lifting plate is slidably connected to the surface of the arc plate through an arc hole, and the cross is fixedly connected to the inner wall of the lifting plate through a sliding hole to facilitate the up and down adjustment of the signal receiving dish and increase stability. The sliding connection between the lifting plate and the hollow round rod increases the convenience of installing the signal receiving dish.

[0004] Chinese patent CN117276844B discloses a radio broadcast signal receiving device. In this invention, firstly, the support poles distributed perpendicular to the horizontal axis drive the scraper to effectively clean the covering material inside the parabolic receiving mechanism, which also facilitates the safe erection of the signal receiving device in snowy environments; secondly, after the parabolic receiving mechanism is cleaned, the automatic retraction and extension of the arc-shaped scraper will not affect the normal reception of wireless signals by the parabolic receiving mechanism.

[0005] The parabolic disc surface of existing disc signal receivers is prone to the accumulation of snow, ice, and debris, which can easily affect the received signal. Most existing technologies require manual cleaning, which is very troublesome. At the same time, traditional devices are prone to disc displacement in strong winds and vibration environments, resulting in unstable signal reception. Existing disc signal receivers are not very adaptable to harsh environments. Summary of the Invention

[0006] The technical problem that this invention aims to solve in view of the above-mentioned prior art is that the surface of the disc in existing disc signal receiving devices is not easy to clean, and the disc is prone to displacement in strong winds and vibration environments, resulting in unstable signal reception. Existing disc signal receiving devices are not adaptable to harsh environments.

[0007] To address the aforementioned problems, this invention provides a signal receiving device for broadcasting and television engineering, comprising a base with a hinged movable arm, a parabolic disc rotatably connected to the top of the movable arm via a stepper motor, an electric support rod fixedly connected to the base, the telescopic end of the electric support rod being hinged to the movable arm, a high-frequency head connected to the fixed end of the stepper motor via a pair of brackets, and a scraper structure for cleaning and assisting in supporting the parabolic disc provided between the pair of brackets. The scraper structure includes a linear guide rail hinged to the base, an arc-shaped scraper driven to rotate by a small motor connected to the movable end of the linear guide rail, the arc-shaped scraper including an arc-shaped surface matching the surface of the parabolic disc, a main hanging arm fixedly connected to the top of the arc-shaped scraper, and a secondary hanging arm opposite to the main hanging arm fixedly connected to the top of the linear guide rail.

[0008] The lower end of the parabolic disc is connected to stabilizing claws that are respectively matched with the main mounting arm and the auxiliary mounting arm;

[0009] When the arc-shaped scraper is in the retracted state, the main and auxiliary hanging arms abut against the stabilizing claws to provide auxiliary support for the parabolic disc. When the arc-shaped scraper is in the extended state, the arc-shaped scraper is in contact with the surface of the parabolic disc. At this time, the movable arm is adjusted to the initial set rotation angle, and the arc-shaped scraper is used to assist in cleaning the rotating parabolic disc.

[0010] In the aforementioned signal receiving device for broadcasting and television engineering, automatic cleaning or stable support of the parabolic disk is achieved during the signal receiving process.

[0011] As a further supplement to this application, solar panels are installed on the top of the high-frequency head and the side of the scraper structure. The solar panels on the high-frequency head are used to power the electric support rod and the stepper motor.

[0012] As a further supplement to this application, an electric heating plate is provided on one side of the arc-shaped scraper, and a heat-conducting layer connected to the electric heating plate is laid on the arc-shaped edge of the arc-shaped scraper.

[0013] As a further supplement to this application, the arc-shaped scraper also includes an electric push rod connected to the arc-shaped scraper, and the telescopic end of the electric push rod is rotatably connected to the movable end of the linear guide rail.

[0014] As a further addition to this application, an auxiliary motor for driving the scraper structure to rotate is installed on the base.

[0015] As a further supplement to this application, the movable end of the linear guide is connected to a slider, and a docking shaft that is rotatably connected to the power output end of a small motor is located inside the slider. The docking shaft is detachably snapped into one end of the arc-shaped scraper.

[0016] As a further supplement to this application, when the scraper structure switches from the support state to the cleaning state, the linear guide rail is first controlled to separate the arc-shaped scraper from the stabilizing claw. Then, the arc-shaped scraper is fully retracted. Next, the electric support rod is controlled to rotate and lower the movable arm until the arc-shaped scraper is located on the upper side of the parabolic disc. Then, the linear guide rail is controlled to move the arc-shaped scraper forward a set distance. Finally, the movable arm is controlled to return to the initial set position. At this time, the arc-shaped scraper is in contact with the surface of the parabolic disc. At this time, the parabolic disc can be rotated by driving the stepper motor. During the rotation, the debris on the parabolic disc is scraped off by the arc-shaped scraper.

[0017] As a further supplement to this application, it also includes an auxiliary system, which includes a processor and has a control module, a monitoring module, a data processing module and a data storage module connected to the processor.

[0018] The monitoring module is responsible for collecting environmental monitoring data and equipment status. The environmental monitoring data includes wind speed data, vibration data, real-time tilt angle of the parabolic disc, and surface image of the parabolic disc.

[0019] The data processing module is used to process and analyze monitoring data, and send corresponding control commands to the control module based on the analysis results;

[0020] The control module is used to receive instructions from the data processing module and control the corresponding associated devices to work.

[0021] The data storage module is used to store monitoring data and processing results.

[0022] In summary, this solution achieves automatic cleaning or stable support of the parabolic disk during signal reception by switching the state of the scraper structure, which can easily improve the stability and efficiency of signal reception and reduce the cost of manual maintenance.

[0032] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0033] Implementation method 1:

[0034] Figure 1 - Figure 6 As shown, a signal receiving device for broadcasting and television engineering includes a base 1 with a hinged movable arm 2. The top end of the movable arm 2 is rotatably connected to a parabolic disk 3 via a stepper motor. An electric support rod 11 is fixedly connected to the base 1, and the telescopic end of the electric support rod 11 is hinged to the movable arm 2. The fixed end of the stepper motor is connected to a high-frequency head 4 via a pair of brackets.

[0035] A scraper structure 5 for cleaning and assisting in supporting the parabolic disc 3 is provided between a pair of supports. The scraper structure 5 includes a linear guide rail 51 hinged to the base 1. An arc-shaped scraper 52 driven to rotate by a small motor is connected to the movable end of the linear guide rail 51. The arc-shaped scraper 52 includes an arc-shaped curved surface that matches the surface of the parabolic disc 3. A main hanging arm 53 is fixedly connected to the top of the arc-shaped scraper 52. A secondary hanging arm 54 opposite to the main hanging arm 53 is fixedly connected to the top of the linear guide rail 51.

[0036] The lower end of the parabolic disc 3 is connected to a stabilizing claw 31 that matches the main mounting arm 53 and the auxiliary mounting arm 54 respectively;

[0037] When the arc-shaped scraper 52 is adjusted to the retracted state, the arc-shaped scraper 52 retracts, and the main hanging arm 53 and the auxiliary hanging arm 54 abut against the stabilizing claw 31 to provide auxiliary support for the parabolic disc 3.

[0038] When the arc-shaped scraper 52 is adjusted to the extended and unfolded state, the arc-shaped scraper 52 is in contact with the surface of the parabolic disc 3. At this time, the movable arm 2 is adjusted to the initial set rotation angle, and the arc-shaped scraper 52 is used to assist in cleaning the rotating parabolic disc 3. In the support state, the arc-shaped scraper 52 supports the disc 3 to lock the disc 3. In the cleaning state, it is unlocked and the disc 3 is rotated by the stepper motor.

[0039] A heating plate is provided on one side of the arc-shaped scraper 52. A heat-conducting layer connected to the heating plate is laid on the arc-shaped edge of the arc-shaped scraper 52. The arc-shaped scraper 52 can be actively heated by the heating plate. When snow accumulates and ice forms on the surface of the parabolic disc 3, the heated arc-shaped scraper 52 can be used to assist in de-icing the parabolic disc 3.

[0040] The arc-shaped scraper 52 also includes an electric push rod connected to the arc-shaped scraper, and the telescopic end of the electric push rod is rotatably connected to the movable end of the linear guide rail 51. The arc-shaped scraper 52 is double-contracted through the electric push rod, which makes it easy to ensure that the arc-shaped scraper 52 can completely leave the coverage area of ​​the parabolic disc 3 when it contracts.

[0041] An auxiliary motor for driving the scraper structure 5 to rotate is installed on the base 1; the scraper structure 5 can be driven to rotate on the base 1 by the auxiliary motor, so as to avoid the scraper structure 5 blocking the parabolic disc 3 when the tilt angle of the parabolic disc 3 is adjusted.

[0042] The movable end of the linear guide 51 is connected to a slider. Inside the slider, a mating shaft rotates and is connected to the power output end of a small motor. Two meshing bevel gears are connected to the mating shaft and the power output end of the small motor, respectively. The mating shaft is detachably engaged with one end of the arc-shaped scraper 52. Figure 6 As shown.

[0043] Solar panels are installed on the top of the high-frequency head 4 and the side of the scraper structure 5. The solar panels on the high-frequency head 4 are used to power the electric support rod 11 and the stepper motor.

[0044] When the scraper structure 5 switches from the support state to the cleaning state, first control the linear guide rail 51 to work, so that the arc-shaped scraper 52 separates from the stabilizing claw 31. Then, the arc-shaped scraper 52 is fully retracted (that is, the arc-shaped scraper 52 is completely within the length range of the linear guide rail 51). Then control the electric support rod 11 to work, so that the movable arm 2 rotates and descends until the arc-shaped scraper 52 is located on the upper side of the parabolic disc 3. Then control the linear guide rail 51 to work, so that the arc-shaped scraper 52 moves forward a set distance. Finally, control the movable arm 2 to return to the initial set position. At this time, the arc-shaped scraper 52 is in contact with the surface of the parabolic disc 3. At this time, the parabolic disc 3 can be rotated by driving the stepper motor. During the rotation, the debris on the parabolic disc 3 is scraped off by the arc-shaped scraper 52.

[0045] When the scraper structure 5 switches from the cleaning state to the support state, the above operation is performed in reverse until the arc-shaped scraper 52 is retracted to one side of the linear guide rail 51 and rotates to a horizontal state. Then, the rotation of the movable arm 2 is adjusted so that the main hanging arm 53 and the auxiliary hanging arm 54 abut against the stabilizing claw 31. At this time, the scraper structure 5 limits and provides auxiliary support for the parabolic disc 3, preventing the parabolic disc 3 from rotating. The electric support rod 11 supports the parabolic disc 3, preventing the movable arm 2 from swaying. At this time, the parabolic disc 3 is supported and stabilized.

[0046] This solution enables automatic cleaning or stable support of the parabolic disc 3 during signal reception, easily improving the stability and efficiency of signal reception. The device design fully considers various practical situations, such as snow accumulation, ice formation, and debris coverage. Through the integrated scraper structure 5 and heating plate, automatic cleaning and de-icing of the parabolic disc 3 are achieved, ensuring clear signal reception. Simultaneously, the coordinated operation of the electric support rod 11 and the stepper motor, along with the flexible switching of the scraper structure, ensures stable support of the parabolic disc 3 in different states, avoiding signal reception instability caused by shaking or tilting.

[0047] The second implementation method:

[0048] Figure 7 As shown, it also includes an auxiliary system, which includes a processor with a control module, a monitoring module, a data processing module and a data storage module connected to it;

[0049] The monitoring module is responsible for collecting environmental monitoring data and equipment status. The environmental monitoring data includes wind speed data, vibration data, real-time tilt angle of parabolic disc 3 and surface image of parabolic disc 3; a wind speed sensor is installed on the base 1 and a vibration sensor is installed on the parabolic disc 3; an image acquisition device is installed at the high frequency head 4.

[0050] The data processing module is used to process and analyze monitoring data, and send corresponding control commands to the control module according to the analysis results. Based on the real-time tilt angle change of the parabolic disc 3, it determines whether to set the scraper structure 5 to provide auxiliary support for the parabolic disc 3.

[0051] The surface state of the object disk 3 is analyzed by the surface image of the object disk 3, and it is determined whether the scraper structure 5 is set to the cleaning state.

[0052] The control module is used to receive instructions from the data processing module and control the operation of the corresponding associated equipment; the associated equipment includes electric support rod 11, stepper motor, auxiliary motor and scraper structure 5, etc.

[0053] The data storage module is used to store monitoring data and processing results.

[0054] This implementation method enables intelligent management and maintenance of signal receiving devices used in broadcasting and television engineering. The processor, as the core of the auxiliary system, efficiently integrates the functions of various modules, ensuring the stable operation of the entire device.

[0055] The monitoring module acquires environmental parameters and equipment status in real time through devices such as wind speed sensors, vibration sensors, and image acquisition devices, providing accurate data support for the data processing module. The data processing module then uses advanced algorithms to perform in-depth analysis of this data, promptly identifying potential problems and sending corresponding control commands to the control module. Based on these commands, the control module precisely regulates associated equipment, such as electric support rods, stepper motors, and scraper structures, to effectively support and clean the parabolic disc 3. This implementation achieves automatic switching between the support and cleaning states of the scraper structure 5, which not only improves the stability and efficiency of signal reception but also easily reduces the cost of manual maintenance.

[0056] In light of current practical needs, the above-described embodiments adopted in this application are not limited to this scope of protection. Various changes made within the knowledge of those skilled in the art without departing from the concept of this application still fall within the protection scope of this invention.
