DETAILED DESCRIPTION
[0030] See also Figure 1-7 The present invention provides a technical solution: an audible and visual safety warning device, comprising a base 1 and a warning sign 2, warning lights 3 are installed on the front and rear sides of the warning sign 2, a communication module 4 is also installed in the warning sign 2, and the communication module 4 is used for information exchange between the device and the control center, a turntable 6 is movably connected in a circular groove 5 on the upper surface of the base 1, a steering motor 7 is fixedly installed in the center of the circular groove 5, and the output end of the steering motor 7 is fixedly connected to the lower surface of the turntable 6 to drive it to rotate.
[0031] Two uprights 10 are symmetrically arranged on the upper surface of the turntable 6. The two uprights 10 are respectively inserted into the two through-holes 11 on the warning sign 2. A driving mechanism 8 is provided on the warning sign 2 to drive the warning sign 2 to move up and down along the uprights 10. A chamber 12 is provided on the warning sign 2 that passes through from top to bottom. A stretching mechanism 9 is provided in a circular hole 23 on one side of the warning sign 2. A sound 13 is provided on the inner wall of the chamber 12 corresponding to the position of the stretching mechanism 9, which can amplify the sound outward by using the stretching mechanism 9. A ring light 14 is also provided on the inner wall of the chamber 12, and the ring light 14 is located outside the sound 13. The warning sign 2 Sensors 15 are provided on both sides for detecting human bodies. A monitoring component 16 for environmental monitoring is also provided on the warning sign 2 and on one side of the extension mechanism 9. As a well-known technology, this device should also be equipped with necessary controllers for controlling various electronic devices. The monitoring component 16 is specifically a monitoring camera-type device that can collect images and sounds of the monitored environment. Based on existing technology, human body recognition is performed on the collected images and feedback is given to the controller so that the turntable 6 can rotate to ensure that the extension mechanism 9 points to the human body. As a relatively mature well-known technology, it will not be elaborated.
[0032] A rotating shaft 17 is movably connected between the two columns 10, and a steering motor 18 is installed in one of the columns 10, which drives the rotating shaft 17 to rotate. A solar panel 19 is fixedly installed on the rotating shaft 17, and a power storage component 20 is installed in the chamber 12 to store the electrical energy converted by the solar panel 19. After the solar panel 19 is rotated to align with the chamber 12, the driving mechanism 8 drives the warning sign 2 to move upward to store the solar panel 19 into the chamber 12. A cover can also be installed on the top of the solar panel 19 to close the opening at the top of the chamber 12, which helps to protect the electronic devices in the chamber 12. This is a conventional choice for those skilled in the art and will not be described in detail.
[0033] A guide groove 21 is defined on the outer side of the column 10 , and a guide block 22 is fixedly connected to a position in the through hole 11 corresponding to the guide groove 21 , and the guide block 22 is slidably connected in the guide groove 21 .
[0034] The driving mechanism 8 includes a driving motor 81 and a driving wheel 82. The driving motor 81 is installed in the mounting groove on the inner wall of the perforation 11. The output end of the driving motor 81 is fixedly connected to the driving wheel 82, and the driving wheel 82 is rollingly connected in the guide groove 21 to drive the warning sign 2 to move on the column 10.
[0035] The extension mechanism 9 includes several extension rings 91 of decreasing diameter, a protective cover 92, an elastic connector 93 and a recovery mechanism 94. The extension rings 91 can be spliced in sequence to form a disc shape. The extension rings 91 at the edge are fixedly connected to the inner wall of the circular hole 23, and the inner side of the extension ring 91 in the center is fixedly connected to the protective cover 92. Adjacent extension rings 91 are connected by elastic connectors 93. The elastic connectors 93 can be used to stagger the extension rings 91 to form a horn-like structure. When the extension mechanism 9 is extended, the extension ring 91 in the center is opposite to the speaker 13. A recovery mechanism 94 is provided in the chamber 12 for pulling back the extension rings 91. Unlike the speaker structure in the prior art, the extension mechanism 9 adopted in this application is based on the panel design of the warning sign. In the retracted state, it is a panel structure. As a warning sign, a warning message can be printed on its outer surface. In the extended state, it forms a horn-like structure for directionally reflecting sound and light. The switching of different states corresponds to different uses, and the footprint is significantly smaller, which contributes to the lightweight design of the warning sign, which is something that a fixed-form speaker structure cannot provide.
[0036] The elastic connecting member 93 includes an L-shaped rod 931, a compression spring 932 and a slot 933. One end of the L-shaped rod 931 is fixedly connected to the back of the smaller one of the adjacent stretching rings 91. A slot 933 is provided on the back of the larger one of the adjacent stretching rings 91 at the position corresponding to the L-shaped rod 931. The compression spring 932 is arranged in the slot 933. The other end of the L-shaped rod 931 is inserted into the slot 933 and connected to the compression spring 932. To ensure that there is space for the compression spring 932 in the slot 933, the width of each stretching ring 91 should increase from the outside to the inside.
[0037] The two recovery mechanisms 94 are symmetrical with respect to the stretching mechanism 9. The recovery mechanism 94 includes a winding motor 941, a mounting frame 942, a roller 943 and a pull rope 944. The winding motor 941 is installed on the inner wall of the chamber 12. The position near the winding motor 941 in the chamber 12 is also movably connected to the roller 943 through the mounting frame 942. The roller 943 is driven by the winding motor 941. One end of the pull rope 944 is fixedly connected to the outer wall of the roller 943, and the other end of the pull rope 944 passes through the warning sign 2 and is fixedly connected to the front of the stretching ring 91 in the center.
[0038] In this technical solution, the winding motor 941, the steering motor 1 7 and the steering motor 2 18 should all be equipped with a self-locking structure, which is a well-known technology and will not be described in detail.
[0039] The extension mechanism 9 also includes a magnetic ring 1 95 and a magnetic ring 2 96. The magnetic ring 1 95 is fixedly connected to the inner wall of the chamber 12 and is located on the outside of the speaker 13. The magnetic ring 2 96 is fixedly connected to the back of the extension ring 91 located in the center. The magnetic ring 1 95 and the magnetic ring 2 96 can fix the extension shape of each extension ring 91 by adsorption.
[0040] The stretching ring 91 is an acrylic transparent ring, and the inner wall of the stretching ring 91 is bonded with an annular reflective film 24, and the width of the annular reflective film 24 is smaller than the width of the stretching ring 91. The light of the ring lamp 14 can pass through the stretching ring 91 and be projected onto the annular reflective film 24 to be reflected in the direction indicated by the stretching mechanism 9. Based on the design of the annular reflective film 24 and the stretching ring 91, the stepped structure formed after the multiple stretching rings 91 are unfolded is utilized. The ring lamp 14 is used as the light source to emit light from the outside to the inside. When the light is reflected into the human eye through the annular reflective film 24, multiple annular apertures are seen from the inside to the outside. The annular design of the annular reflective film 24 helps to fully reflect the light into the eyes, which can serve as a warning to people and can also be used as a lighting lamp for lighting.
[0041] When the device is working:
[0042] The warning device is mounted on a work surface using the base 1. Warning words are sprayed on the surface of the warning sign 2. The solar panel 19 is located on the upper side of the warning sign 2. The steering motor 18 adjusts the angle of the solar panel 19 to obtain a better lighting angle. In the working state, the side of the warning sign 2 without the extension mechanism 9 is facing the crowd, and the side with the extension mechanism 9 is facing the warning area. The sensor 15 detects whether there are people passing by on the left and right sides of the warning sign 2.
[0043] When someone passes by, the warning light 3 flashes to warn, the speaker 13 plays a warning message, and the steering motor 7 drives the turntable 6 to rotate so that the monitoring component 16 monitors the human body and records the picture and sound;
[0044] When the monitoring component 16 can still detect the human body after the warning, the winding motor 941 is unlocked, the compression spring 932 rebounds, and each extension ring 91 extends to form a horn-shaped structure. The magnetic ring 1 95 and the magnetic ring 2 96 are attracted, and the sound emitted by the speaker 13 is accurately transmitted to the position of the person who breaks into the warning area through the guidance of the extension mechanism 9. The ring light 14 works, and the strong light emitted is projected through the extension ring 91 and reflected on the annular reflective film 24 to the position of the human body to warn, and the image is transmitted to the cloud alarm through the communication module 4.
[0045] Various modifications to these embodiments will be apparent to those skilled in the art. The general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will be accorded the widest scope consistent with the principles and novel features disclosed herein.
