Description

Technical Field

[0001] The present invention belongs to the technical field of anti-intrusion equipment, and in particular relates to a comprehensive intelligent alarm device for preventing foreign objects from intruding into a power station. Background Art

[0002] In the process of ensuring the normal operation of power stations and the safety of personnel, it is crucial to take effective measures to prevent unauthorized intrusion and prevent foreign objects from damaging facilities. In view of this, power stations currently generally implement a series of protection measures, mainly covering the use of image acquisition equipment (such as high-definition cameras) and warning devices (including flashing light warnings, sound alarms) Anti-intrusion alarm systems, as well as the configuration of electronic fences. These advanced anti-intrusion systems can monitor most abnormal activities or unauthorized intrusions in real time, and quickly issue alarms when these behaviors are detected, thereby protecting power facilities from animal intrusions, illegal intrusions or other external risks.

[0003] Although the anti-intrusion technology equipment currently used has been widely deployed and applied in many occasions, in actual use, these devices still face some tests and challenges:

[0004] First, as a passive means of protection, the warning mechanism of the electronic fence is activated only when the intruding foreign object touches the fence. This reaction mode shows a certain lag in actual application and cannot timely warn of potential risk events.

[0005] Secondly, anti-intrusion alarms are often installed in fixed positions, which makes them less adaptable to changes in the surrounding environment. For example, the growth of trees and shrubs in the surrounding natural environment may block the line of sight of the image acquisition component, resulting in blind spots in monitoring. In addition, extreme weather conditions, such as violent storms, sandstorms, haze and other severe climates, will not only limit the line of sight of the image acquisition component, but also greatly reduce the propagation distance of the warning sound and light, thereby reducing the effective coverage area of ​​the warning component and affecting the reliability and efficiency of the anti-intrusion system.

[0006] Based on the above problems, this application proposes a comprehensive intelligent alarm device for preventing foreign objects from intruding into a power station to improve the above problems and further improve the safety protection level of the power station. Summary of the invention

[0045] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0046] Please see attached Figures 1 to 4 As shown, it is the first embodiment of the present invention, which provides a comprehensive intelligent alarm device for preventing foreign objects from intruding in a power station, including multiple bases 10, the upper ends of the bases 10 are fixed with connecting pipes 11 and columns 12 in order from bottom to top, a protective pipe 13 is fixed between two adjacent connecting pipes 11, and a protective net 14 is fixed between two adjacent columns 12. The multiple bases 10, the connecting pipes 11, the columns 12, the protective pipes 13 and the protective net 14 together constitute a semi-enclosed fence structure, and an openable and closable protective door is installed inside any protective net 14, and the semi-enclosed fence structure can be entered and exited through the protective door, a speaker 15 and a control element 16 are fixed inside a plurality of columns 12, and the speaker 15 and the control element 16 located inside the same column 12 are electrically connected through a wire, and a track 17 is fixed on the top of the multiple columns 12, and the cross-sectional shape of the track 17 in the vertical direction is an I-shaped, and also includes:

[0047] The warning unit 20 is mounted on the upper end of the track 17, and the control element 16 is connected to the warning unit 20. The warning unit 20 can collect images of the outside of the semi-enclosed fence structure and can warn of potential intrusions;

[0048] The walking unit 30 is installed between the track 17 and the warning unit 20. The walking unit 30 can drive the warning unit 20 to move along the track 17.

[0049] A power supply unit 40, which is installed between the track 17 and the traveling unit 30, and is used to transmit electric energy to the traveling unit 30;

[0050] Among them, the cross-sectional shapes of the connecting tube 11, the columns 12 and the protective tube 13 are all circular, the interiors of the multiple connecting tubes 11, the multiple columns 12 and the multiple protective tubes 13 are interconnected, and the multiple connecting tubes 11, the multiple columns 12 and the multiple protective tubes 13 together form a sound transmission cavity.

[0051] It should be noted that a remote server is also used in conjunction with the device. The remote server is connected to the early warning unit 20 via a wireless signal, and the remote server can analyze and process the images collected by the early warning unit 20.

[0052] Furthermore, in the present embodiment, the horizontal cross-sectional shape of the track 17 is a rectangle, and the number of the speaker 15, the control element 16, the warning unit 20 and the walking unit 30 is at least one. Of course, the horizontal cross-sectional shape of the track 17, the number of speakers 15, the number of control elements 16, the number of warning units 20 and the number of walking units 30 can be adjusted according to actual usage requirements and / or environmental factors and / or coverage range, and no specific limitation is constituted herein.

[0053] In this embodiment, when the power station is protected against intrusion, the walking unit 30 is started, and the early warning unit 20 is driven by the walking unit 30 to move along the track 17. The early warning unit 20 collects images near the semi-enclosed fence structure in real time during the movement along the track 17. When a potential intrusion event or an ongoing intrusion event is found, a signal is transmitted to the control element 16 through the early warning unit 20, and the speaker 15 is started through the control element 16, so that the speaker 15 emits a warning sound. The warning sound emitted by the speaker 15 quickly propagates inside the sound transmission cavity, so that multiple connecting pipes 11, multiple columns 12 and multiple protection pipes 13 synchronously emit warning sounds to warn or / and drive away invading foreign objects. In addition, the warning sound will not be attenuated by external factors such as wind, rain, dust, etc. during the propagation inside the sound transmission cavity, thereby avoiding the phenomenon that the device is affected by external environmental factors and the coverage is reduced. At the same time, the movable early warning unit 20 can effectively avoid the phenomenon of obstruction of vision caused by tree growth during movement, thereby improving the protection performance and application scope of the device.

[0054] It should be noted that, in the present embodiment, the multiple connecting tubes 11, the multiple columns 12 and the multiple protective tubes 13 together form a sound transmission cavity which is a closed pipe. The closed pipe can prevent foreign objects from entering the sound transmission cavity, causing the warning sound to be attenuated due to the influence of foreign objects when propagating in the sound transmission cavity.

[0055] In a preferred embodiment, the inherent resonance frequency of the connecting tube 11, the column 12 and the protective tube 13 is recorded as F1, and the frequency of the sound wave released when the speaker 15 is in working state is recorded as F2, and F1=F2.

[0056] It should be noted that the sound waves released when the speaker 15 is in working state refer to the warning sound emitted. The material of the connecting tube 11, the column 12 and the protective tube 13 is preferably the same metal. The metal material has a high acoustic conductivity and can effectively conduct sound. The method for obtaining the inherent resonance frequency of the connecting tube 11, the column 12 and the protective tube 13 and the method for controlling the sound wave frequency released by the speaker 15 are all existing mature technologies and will not be further elaborated here.

[0057] In this embodiment, when the frequency of the warning sound is the same as the inherent resonance frequency of the sound transmission cavity, pipeline and acoustic resonance can occur, producing a resonance effect. The resonance effect will greatly enhance the sound conduction effect, so that the warning sound inside the sound transmission cavity can be amplified, thereby improving the warning effect of the device and avoiding the attenuation of the warning sound inside the sound transmission cavity.

[0058] Secondly, please also refer to Figure 2 and Figure 5 As shown, the early warning unit 20 includes a protective box 21, a bracket 22, an image acquisition element 23, a warning element 24 and a bird-repelling element 25. The protective box 21 is assembled at the upper end of the track 17. A control module and a power management module are fixed inside the protective box 21. The control module and the control element 16 are connected. Wireless signal transceiver modules are provided inside the control module and the control element 16. Wireless signal transmission is performed between the control module and the remote service end, and between the control module and the control element 16 through the wireless signal transceiver module. The bracket 22 is fixed to the upper end of the protective box 21. A mounting base plate is fixed on the outer side of the bracket 22. The image acquisition element 23, the warning element 24 and the bird-repelling element 25 are fixed to the upper end of the mounting base plate in sequence, and the control module and the image acquisition element 23, the control module and the warning element 24, the control module and the bird-repelling element 25, the power management module and the image acquisition element 23, the power management module and the warning element 24, the power management module and the bird-repelling element 25, and the power management module and the control module are all electrically connected through wires.

[0059] Furthermore, in the present embodiment, the bird-repelling element 25 is preferably an ultrasonic bird-repelling device, and the number of the image acquisition element 23, the warning element 24 and the bird-repelling element 25 is at least one. Of course, the number of the image acquisition element 23, the warning element 24 and the bird-repelling element 25 can be adjusted according to actual usage requirements, and is not specifically limited here.

[0060] In this embodiment, images near the semi-enclosed fence structure are collected by the image acquisition element 23 and transmitted to the remote server through the control module for processing. If the animal species or human face in the image cannot be identified, the early warning unit 20 is driven by the walking unit 30 to move toward the invaded point in order to obtain a clearer image. The warning element 24 can emit a light warning to drive away the invading person or animal, and the bird-repelling element 25 can send ultrasonic waves to drive away birds.

[0061] It should be noted that the outer side of the bracket 22 can also be equipped with a loudspeaker according to the use requirements to issue a warning sound to warn or drive away the intruder through a verbal warning.

[0062] Next, please refer to Figure 6 and Figure 8The walking part 30 includes a U-shaped bottom plate 31, a driving motor 32 and a plurality of rollers 33. The U-shaped bottom plate 31 is slidably connected to the upper end of the track 17, and the U-shaped bottom plate 31 is fixedly connected to the protective box 21. The driving motor 32 is fixed to one side of the U-shaped bottom plate 31. The plurality of rollers 33 are rotatably connected to the two sides of the inside of the U-shaped bottom plate 31 through ball bearings, and the plurality of rollers 33 roll on the two sides of the inside of the track 17, wherein one roller 33 is fixedly connected to the output end of the driving motor 32, and the driving motor 32 is electrically connected to the control module through a wire.

[0063] In this embodiment, the image near the semi-enclosed fence structure is collected in real time by the image acquisition element 23. When a potential intrusion event or an ongoing intrusion event is found, the control element 16 is started, and a warning sound is issued through the speaker 15, so that the connecting pipe 11, the column 12 and the protective pipe 13 synchronously issue a warning sound. At the same time, the drive motor 32 is started to rotate the output end of the drive motor 32. By fixing the drive motor 32 and the roller 33, the drive motor 32 drives the roller 33 to rotate, so that the roller 33 rolls inside the track 17. By the rotational connection between the roller 33 and the U-shaped bottom plate 31, the roller 33 drives the U-shaped bottom plate 31 to move. By the fixed connection between the U-shaped bottom plate 31 and the protective box 21, the U-shaped bottom plate 31 drives the early warning unit 20 to move in the direction of the invasion to obtain a clearer image. At the same time, the warning effect of the warning element 24 and the bird-repelling element 25 can be improved to avoid the phenomenon that the warning effect of the warning element 24 and the bird-repelling element 25 is reduced due to the long distance from the invasion point.

[0064] In a preferred embodiment, an anti-skid bushing is disposed on the outer side of the roller 33, and a plurality of anti-skid grooves are evenly formed on the outer side of the anti-skid bushing.

[0065] In this embodiment, the provision of the anti-skid bushing can increase the friction between the roller 33 and the track 17, thereby preventing the roller 33 from slipping against the track 17 during rotation, and ensuring that the device can operate stably.

[0066] Please refer again Figure 7 and Figure 8The power supply unit 40 includes a plurality of shells 41, a plurality of carbon brushes 42, a first electrode sheet 43 and a second electrode sheet 44. The plurality of shells 41 are respectively fixed on both sides of the inside of the U-shaped bottom plate 31, and the plurality of carbon brushes 42 are respectively slidably connected to the inside of the shells 41, and the plurality of carbon brushes 42 and the power management module are electrically connected through wires. The first electrode sheet 43 and the second electrode sheet 44 are respectively assembled on both sides of the upper end of the inside of the track 17, and the plurality of carbon brushes 42 correspond to the carbon brush 42 and the first electrode sheet 43, respectively, and the corresponding carbon brushes 42 and the first electrode sheet 43, as well as the carbon brushes 42 and the second electrode sheet 44 are all in contact with each other, and the control element 16 and the first electrode sheet 43, as well as the control element 16 and the second electrode sheet 44 are electrically connected through wires.

[0067] Here, a plurality of power supply wires are disposed on the control element 16 , and the plurality of power supply wires penetrate through the track 17 and are respectively connected to the first electrode sheet 43 and the second electrode sheet 44 .

[0068] It should be noted that the first electrode sheet 43 and the second electrode sheet 44 are connected to the power grid through wires to transmit electric energy for the operation of the device.

[0069] In this embodiment, during the operation of the walking part 30, the roller 33 is driven to roll on the track 17, and drives the U-shaped bottom plate 31 and the early warning part 20 to move synchronously. Through the fixed connection between the U-shaped bottom plate 31 and the shell 41, the U-shaped bottom plate 31 drives the shell 41 to move synchronously. Since the carbon brush 42 is slidably connected to the inside of the shell 41, the shell 41 moves synchronously with the U-shaped bottom plate 31 and the carbon brush 42. Since the corresponding carbon brush 42 and the first electrode sheet 43 and the carbon brush 42 and the second electrode sheet 44 are in contact with each other, the carbon brush 42 is used to transmit electric energy to other electrical components to ensure the stable operation of the device. At the same time, by respectively assembling the first electrode sheet 43 and the second electrode sheet 44 on both sides of the upper end of the track 17, it can be avoided that the first electrode sheet 43 and / or the second electrode sheet 44 come into contact with rainwater in rainy and snowy weather, thereby causing the rainwater to conduct electricity.

[0070] In a preferred embodiment, insulating slots 45 are installed between the track 17 and the first electrode sheet 43 and between the track 17 and the second electrode sheet 44 , and the shell 41 and the insulating slots 45 are both made of insulating materials.

[0071] It should be noted that the rail 17 and the insulating slot 45 , the rail 17 and the first electrode sheet 43 , and the rail 17 and the second electrode sheet 44 are all fixedly connected.

[0072] In this embodiment, the housing 41 and the insulating slot 45 made of insulating material can prevent the housing 41 and the track 17 from being electrically conductive and causing electric shock to personnel.

[0073] Please refer again Figure 7 and Figure 8 A plurality of elastic elements 46 are mounted between the housing 41 and the carbon brush 42. In an initial state, the elastic elements 46 are in a compressed state.

[0074] In this embodiment, when the U-shaped bottom plate 31 drives the shell 41 and the carbon brush 42 to move, since the carbon brush 42 and the first electrode sheet 43 as well as the carbon brush 42 and the second electrode sheet 44 are in contact with each other, the carbon brush 42 will gradually wear out during the movement. The elastic element 46 in a compressed state can keep the carbon brush 42 and the first electrode sheet 43 as well as the carbon brush 42 and the second electrode sheet 44 in contact with each other at all times, thereby ensuring stable operation of the device.

[0075] The working principle of the present invention is:

[0076] The image near the semi-enclosed fence structure is collected by the image acquisition element 23, and transmitted to the remote service end through the control module for processing. If the animal species or human face in the image cannot be identified, the drive motor 32 is started to drive the U-shaped bottom plate 31 and the early warning unit 20 to move toward the invaded point in order to obtain a clearer image. The warning element 24 can emit a light warning to drive the invading person or animal, and the bird-repelling element 25 can send an ultrasonic wave to drive away the birds. At the same time, a signal is transmitted to the control element 16 through the control module, and the speaker 15 is started through the control element 16, so that the speaker 15 emits a warning sound. The warning sound emitted by the speaker 15 quickly propagates inside the sound transmission cavity and produces a resonance effect, so that the multiple connecting tubes 11, the multiple columns 12 and the multiple protective tubes 13 synchronously emit warning sounds to warn or / and drive away the invading foreign objects. In addition, the warning sound will not be affected by external factors such as wind, rain, dust, etc. during the propagation inside the sound transmission cavity, and will not be attenuated, so as to avoid the phenomenon that the device is affected by external environmental factors and the coverage is reduced.

[0077] The above are only preferred embodiments of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention.
