Technical Field
[0001] The utility model relates to the technical field of mine safety warning, and particularly relates to a safety warning device for mine safety. Background Art
[0002] In the process of mine production, the excavation operation not only consumes the most manpower and material resources and occupies the most funds, but also has the greatest potential for reducing the mining cost. The excavation operation is a relatively dangerous job, and dangerous situations may occur during the work. Especially in the mine stope, due to the complex underground structure and poor light, warning devices need to be used at the mine construction site to warn workers not to enter some dangerous areas, such as deep pits, falling rock areas, etc., to play a warning role for dangerous areas. The warning device generally uses an audible and visual alarm lamp, which can not only emit red warning lights, but also emit a warning alarm sound through a buzzer when danger occurs.
[0003] During the use of the existing warning devices on the mine site, the mine site is open, and the traditional audible and visual alarm is weak, resulting in the warning of the warning device being not obvious and causing the problem of insufficient functionality of the warning device. Summary of the Utility Model

DETAILED DESCRIPTION
[0023] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0024] The present invention is further described in detail below in conjunction with the embodiments:
[0025] like Figure 1-6 As shown, the utility model provides a safety warning device for mine safety, including a fixed rod 1, a transparent protective cover 2 and a warning light 5. The top of the fixed rod 1 is rotatably connected to a mounting seat 4 through a sleeve shaft. The upper surface of the mounting seat 4 is provided with a focusing convex lens 7 for focusing the warning light 5. The bottom of the mounting seat 4 is provided with a driving device for driving the mounting seat 4 to rotate. A lens positioning groove 9 is provided at the bottom of the focusing convex lens 7.
[0026] When the warning light 5 is powered on and starts to emit light, its light will be focused by the focusing convex lens 7 to form a directional path perpendicular to the plane of the focusing convex lens 7. At this time, the warning light 5 forms a lantern with multiple highly focused light beams. The rotation of the lantern creates a regular flashing effect, which can spread the light farther and improve the warning effect.
[0027] The opening of the lens positioning groove 9 facilitates the installation of the focusing convex lens 7. At the same time, the light generated by the warning light 5 enters the focusing convex lens 7 at a certain angle, and is emitted through the glass medium and enters the missing part of the lens, that is, the air inside the lens positioning groove 9 with a smaller density. The light will be refracted, and then the light will continue to propagate in a straight line until the light hits the other side of the missing part again. Then the light continues to refract, so that the light is offset and returns to the previous propagation direction. Therefore, the opening of the lens positioning groove 9 will not affect the propagation direction of the light, while reducing the overall weight of the focusing convex lens 7, it also meets its installation requirements.
[0028] The upper surface of the mounting base 4 is fixedly connected with a lens positioning block 8 inserted into the lens positioning groove 9. The warning light 5 is located at the center of the top of the mounting base 4. The inner wall of the transparent protective cover 2 is fixedly connected with a protective cover rubber ring 10.
[0029] The number of the condenser convex lenses 7 is at least two and at most six. The condenser convex lenses 7 are annularly arrayed on the top of the mounting base 4.
[0030] As Figure 1-6 shown, on the basis of Embodiment 1, the present utility model provides a technical solution: Preferably, an auxiliary mounting groove for placing a driving device is formed at the top of the fixing rod 1. The driving device includes a central rod 11 fixedly connected to the center of the bottom of the mounting base 4, a mounting gear 12 fixedly sleeved on the outer wall of the central rod 11, and a driving motor 13 meshed with the outer wall of the mounting gear 12 through gears.
[0031] The bottom end of the central rod 11 is rotatably connected to the bottom of the inner wall of the auxiliary mounting groove, and the bottom end of the driving motor 13 is fixedly connected to the inner wall of the auxiliary mounting groove.
[0032] The bottom of the transparent protective cover 2 is fixedly connected with a threaded collar 3, and a receiving threaded groove 6 is formed at the top of the mounting base 4.
[0033] The threaded collar 3 is threadedly connected to the receiving threaded groove 6 through the inner wall thread.
[0034] Next, the working principle of the safety warning device for mine safety will be specifically described.
[0035] As Figure 1-6 shown, when in use, when warning the staff in the mine, an external power source starts the mounting gear 12, which drives the central rod 11 to drive the mounting base 4 to rotate. During the rotation of the mounting base 4, the warning light 5 and the condenser convex lenses 7 mounted thereon will rotate synchronously.
[0036] When the warning light 5 is energized and starts to emit light, its light will be focused by the condenser convex lenses 7 to form a direction path perpendicular to the plane of the condenser convex lenses 7. At this time, the warning light 5 forms a lantern with multi-height focused light beams. By rotating the lantern, a regularly flashing effect is created, so that the light can be transmitted farther and the warning effect is improved.
[0037] The opening of the lens positioning groove 9 facilitates the installation of the focusing convex lens 7. At the same time, the light generated by the warning light 5 enters the focusing convex lens 7 at a certain angle, and is emitted through the glass medium and enters the missing part of the lens, that is, the air inside the lens positioning groove 9 with a smaller density. The light will be refracted, and then the light will continue to propagate in a straight line until the light hits the other side of the missing part again. Then the light continues to refract, so that the light is offset and returns to the previous propagation direction. Therefore, the opening of the lens positioning groove 9 will not affect the propagation direction of the light, while reducing the overall weight of the focusing convex lens 7, it also meets its installation requirements.
[0038] It should be noted that, in this article, the terms "comprises", "includes" or any other variants are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or still includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "including one..." do not exclude the existence of other identical elements in the process, method, article or device including the elements. The above generally describes the utility model in detail, but on the basis of the utility model, some modifications or improvements can be made to it, which is obvious to a general technician in the technical field. Therefore, modifications or improvements that do not deviate from the spirit of the utility model are within the scope of protection of the utility model.
