Description

Technical Field

[0001] The invention belongs to the technical field of plateau hard rock tunnel safety, and specifically refers to a safety warning device for monitoring and measuring plateau hard rock tunnels. Background Art

[0002] Tunnel construction is a high-risk and complex project. To ensure the safety and smooth completion of tunnel construction, real-time monitoring and measurement of the tunnel interior is required. Especially in plateau hard rock areas, due to the complexity of geological conditions, the construction risk is even greater, so it is necessary to develop a safety warning device suitable for use in this area.

[0003] However, traditional monitoring methods have certain limitations, especially for tunnel construction. Traditional monitoring methods are more difficult. The camera itself is not sufficiently protected and does not have a heat dissipation function. When a fire or dust explosion occurs inside the tunnel, the camera is easily impacted and subjected to high temperature and loses its ability to work instantly. Therefore, a safety warning device for monitoring and measuring plateau hard rock tunnels is proposed. Summary of the invention

[0004] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a safety warning device for monitoring and measuring plateau hard rock tunnels to solve or alleviate the technical problems existing in the prior art and at least provide a beneficial alternative.

[0005] The technical solution adopted by the present invention is as follows: The present invention proposes a safety warning device for monitoring and measuring plateau hard rock tunnels, including a base plate, a protective component fixedly connected to the top side of the base plate, a bracket fixedly connected to the middle of the top of the base plate, a connecting block rotatably connected to the inner cavity of the bracket, a camera body fixedly connected to the top of the connecting block, a sealing component is provided in the inner cavity of the protective component, a baffle is fixedly connected to one side of the bottom of the base plate, and a cleaning component is provided on one side of the baffle.

[0006] As a further preferred embodiment of the present invention, the protective assembly includes guide rails and positioning bolts. The two guide rails are symmetrically fixedly connected to the two sides of the top of the base plate. Slide grooves are symmetrically opened on both sides of the guide rails. A protrusion is slidably connected to the inner cavity of the slide groove. A protective cover is slidably sleeved on the guide rail. The cross-section of the protective cover is set to be U-shaped, and the protrusion is fixedly connected to one side of the sliding connection between the protective cover and the guide rail. Fixed plates are symmetrically fixedly connected to the two sides of the bottom of the protective cover, and a number of positioning bolts fix the fixed plate to the guide rail.

[0007] As a further preferred embodiment of the present invention, the cleaning assembly includes a driving gear and a driven gear, the driving gear and the driven gear are rotatably connected to one side of the baffle, the driving gear is meshed with the driven gear, one side of the driving gear is fixedly connected to a motor, and one side of the driven gear is fixedly connected to a rotating rod.

[0008] As a further preferred embodiment of the present invention, the rotating rod passes through the baffle and is fixedly connected to a cleaning scraper, and a cleaning brush is fixedly sleeved on the cleaning scraper.

[0009] As a further preferred embodiment of the present invention, a plurality of heat dissipation holes are evenly and symmetrically opened on both side walls of the protective cover, and a dustproof net is fixedly connected to the inner cavity of the heat dissipation holes.

[0010] As a further preferred embodiment of the present invention, the sealing assembly includes a cylinder, which is fixedly connected to the top of the inner cavity of the protective cover, and the bottoms of the two cylinders are fixedly connected to rubber pads, and the rubber pads are symmetrically arranged on both side walls of the protective cover, and the outer wall of the protective cover is fixedly connected to a first temperature sensor, and one side of the top of the inner cavity of the protective cover is fixedly connected to a second temperature sensor, and the side of the top of the inner cavity of the protective cover away from the second temperature sensor is fixedly connected to a controller.

[0011] The beneficial effects achieved by the present invention using the above structure are as follows:

[0012] First, by setting up a protective component, etc., before using the camera body, the protective cover is slid on the guide rail, and the protrusion slides synchronously in the slide groove at the same time, which is the sliding limit guide of the protective cover, that is, the protective cover is slidably installed on the bottom plate. After the sliding installation is completed, the positioning bolt is screwed to fix the fixing plate and the guide rail to limit the position of the protective cover, so that the protective cover is fixedly installed on the bottom plate, so that the protective cover covers the outside of the camera body to protect the camera body, which can prevent the camera body from being damaged by falling stones in the hard rock tunnel of the plateau, and help to extend the service life of the camera body. In addition, the material of the protective cover is set to rock wool, which has a good fireproof effect. When in use, the camera body can be fireproofed to prevent the fire from directly burning the camera body in the event of a fire, thereby further strengthening the protection of the camera body;

[0013] Second, by setting a cleaning component, when the camera body needs to be cleaned, the motor is started to drive the active gear to rotate, so that the driven gear drives the rotating rod to rotate, so that the cleaning scraper and the cleaning brush swing left and right, so that the left and right swing of the cleaning brush in the wet and cold tunnel can wipe and clean the lens of the camera body to ensure the cleanliness of the camera body, so that the camera body can be normally monitored and controlled in the tunnel, thereby improving the applicability of the camera body;

[0014] 3. By setting sealing components, heat dissipation holes, etc., when a fire or dust explosion occurs in the tunnel and causes the external temperature to rise rapidly, as the external temperature becomes higher than the internal temperature, the first temperature sensor and the second temperature sensor sense the temperature difference and transmit the signal to the controller. The controller starts the cylinder to push the rubber pad to move and close the heat dissipation holes, thereby blocking the external heat. This can effectively protect the camera body so that it can continue to work and prevent the camera body from instantly losing its working ability due to impact and high temperature invasion when a fire or dust explosion occurs in the tunnel.

[0024] like Figures 1 to 5 As shown, the present invention proposes a safety warning device for monitoring and measuring plateau hard rock tunnels, including a base plate 1, a protective component 3 is fixedly connected to the top side of the base plate 1, a bracket 4 is fixedly connected to the middle of the top of the base plate 1, a connecting block 5 is rotatably connected to the inner cavity of the bracket 4 through a rotating shaft, a camera body 6 is fixedly connected to the top of the connecting block 5, a sealing component 8 is provided in the inner cavity of the protective component 3, a baffle 2 is fixedly connected to one side of the bottom of the base plate 1, and a cleaning component 7 is provided on one side of the baffle 2.

[0025] A plurality of heat dissipation holes 9 are evenly and symmetrically opened on both side walls of the protective cover 3.1, and the heat dissipation holes 9 are distributed in a straight line in the middle of the side walls of the protective cover 3.1. A dustproof net 10 is fixedly connected to the inner cavity of the heat dissipation hole 9, and the dustproof net 10 can effectively prevent external dust and mosquitoes from entering the interior of the protective cover 3.1.

[0026] The protection component 3 includes a guide rail 3.2 and a positioning bolt 3.4. The two guide rails 3.2 are symmetrically fixedly connected to the two sides of the top of the base plate 1. Slide grooves 3.6 are symmetrically opened on both sides of the guide rails 3.2, and the cross-section of the slide groove 3.6 is semicircular. A protrusion 3.5 is slidably connected to the inner cavity of the slide groove 3.6. The cross-section of the protrusion 3.5 is semicircular, and the protrusion 3.5 and the slide groove 3.6 match each other. A protective cover 3.1 is slidably sleeved on the guide rail 3.2. The cross-section of the protective cover 3.1 is set to be U-shaped. The lower cross-section of one side of the protective cover 3.1 is set to be U-shaped, and the protrusion 3.5 is fixedly connected to one side of the protective cover 3.1 and the guide rail 3.2. Fixed plates 3.3 are symmetrically fixedly connected on both sides of the bottom of the protective cover 3.1. A number of positioning bolts 3.4 fix the fixed plate 3.3 to the guide rail 3.2. Before using the camera body 6, the protective cover 3.1 is slid on the guide rail 3.2, and the protrusion 3.5 slides synchronously in the slide groove 3.6, thereby providing a sliding limit guide for the protective cover 3.1, that is, the protective cover 3.1 is slidably installed on the base plate 1. After the sliding installation, the positioning bolt 3.4 is screwed to fix the fixing plate 3.3 and the guide rail 3.2 to limit the position of the protective cover 3.1, so that the protective cover 3.1 is fixedly installed on the base plate 1, so that the protective cover 3.1 covers the outside of the camera body 6 to protect the camera body 6, which can prevent the camera body 6 from being damaged by falling stones in the hard rock tunnel of the plateau, and help to extend the service life of the camera body 6. In addition, the material of the protective cover 3.1 is set to rock wool, which has a good fireproofing effect. When in use, it can be used to prevent the camera body 6 from being directly burned by the fire in the event of a fire, thereby further strengthening the protection of the camera body 6.

[0027] The cleaning assembly 7 includes a driving gear 7.1 and a driven gear 7.2, which are rotatably connected to one side of the baffle 2 through a bearing, the driving gear 7.1 and the driven gear 7.2 are meshed and connected, a motor 7.3 is fixedly connected to one side of the driving gear 7.1, and a rotating rod 7.4 is fixedly connected to one side of the driven gear 7.2. The rotating rod 7.4 penetrates the baffle 2 and is fixedly connected to a cleaning scraper 7.5, and a cleaning brush 7.6 is fixedly sleeved on the cleaning scraper 7.5.

[0028] The sealing assembly 8 comprises a cylinder 8.1, which is fixedly connected to the top of the inner cavity of the protective cover 3.1, and rubber pads 8.2 are fixedly connected to the bottom of the two cylinders 8.1. The rubber pads 8.2 are symmetrically arranged on the two side walls of the protective cover 3.1, and a first temperature sensor 8.3 is fixedly connected to the outer wall of the protective cover 3.1. A second temperature sensor 8.4 is fixedly connected to one side of the top of the inner cavity of the protective cover 3.1, and a controller 8.5 is fixedly connected to the side of the top of the inner cavity of the protective cover 3.1 away from the second temperature sensor 8.4. When a fire or dust explosion occurs in the external environment causing the external temperature to rise rapidly, as the external temperature becomes higher than the internal temperature, the first temperature sensor 8.3 and the second temperature sensor 8.4 sense the temperature difference and transmit the signal to the controller 8.5. The controller 8.5 starts the cylinder 8.1 to push the rubber pad 8.2 to move, thereby closing the heat dissipation hole 9, thereby blocking the hot air in the plateau hard rock tunnel, which can effectively protect the camera body 6 so that it can continue to work and prevent the camera body 6 from instantly losing its working ability due to impact and high temperature invasion when a fire or dust explosion occurs in the plateau hard rock tunnel.

[0029] During specific use, in Example 1, when installing this device, before using the camera body 6, first slide the protective cover 3.1 on the guide rail 3.2, and at the same time, the protrusion 3.5 slides synchronously in the slide groove 3.6, so as to guide the sliding limit of the protective cover 3.1, that is, the protective cover 3.1 is slidably installed on the base plate 1. After the sliding installation, the positioning bolt 3.4 is screwed to fix the fixing plate 3.3 and the guide rail 3.2 to limit the position of the protective cover 3.1, so that the protective cover 3.1 is fixedly installed on the base plate 1, so that the protective cover 3.1 covers the outside of the camera body 6 to protect the camera body 6, which can prevent the camera body 6 from being damaged by falling stones in the hard rock tunnel of the plateau, and help to extend the service life of the camera body 6, and the material of the protective cover 3.1 is set to rock wool, which has a good fireproof effect.

[0030] Specifically, the camera body 6 can be fireproofed during use to prevent the fire from directly burning the camera body 6 when a fire occurs, thereby further strengthening the protection of the camera body 6. When a fire or dust explosion occurs in a plateau hard rock tunnel, causing the external temperature to rise rapidly, as the temperature in the plateau hard rock tunnel is higher than the internal temperature, the first temperature sensor 8.3 and the second temperature sensor 8.4 sense the temperature difference and transmit the signal to the controller 8.5. The controller 8.5 starts the cylinder 8.1 to push the rubber pad 8.2 to move and close the heat dissipation hole 9, thereby blocking the external heat, which can effectively protect the camera body 6 so that it can continue to work and prevent the camera body 6 from losing its working ability instantly due to impact and high temperature invasion when a fire or dust explosion occurs in the external environment.

[0031] Embodiment 2. This embodiment is based on the above embodiment. When the humid air in the tunnel needs to clean the camera body 6, the motor 7.3 is started to drive the driving gear 7.1 to rotate, so that the driven gear 7.2 drives the rotating rod 7.4 to rotate, so that the cleaning scraper 7.5 and the cleaning brush 7.6 swing left and right. The left and right swing of the cleaning brush 7.6 can wipe and clean the lens of the camera body 6 to ensure the cleanliness of the camera body 6, so that the camera body 6 can be used normally in the tunnel, thereby improving the applicability of the camera body 6.
