Description

Technical Field

[0001] The present invention relates to the field of measurement technology, in particular to a tower tilt early warning device and a usage method thereof. Background Art

[0002] Poles and towers (including electric poles and electric towers, so the quantifier of poles and towers in the present invention is "individual"), especially poles and towers located on high-voltage lines, are prone to tilting and even toppling due to various natural and man-made influences, which will bring safety hazards.

[0003] Although there are certain requirements for the verticality of the tower when it is buried, it is impossible to know in time whether its tilt angle exceeds the safety range during subsequent use, and it is impossible to make timely adjustments. Summary of the Invention

[0004] The main problem solved by the present invention is how to send out an early warning signal in time after a pole tower tilts.

[0005] A tower tilt warning device, characterized by comprising a blue laser module, a yellow fluorescent sheet, a red fluorescent body, a lampshade, and a fixed end. The blue laser module is freely suspended in the lampshade, and the blue laser it emits is vertically downward. When the device is placed vertically, the yellow fluorescent sheet is located directly below the blue laser.

[0006] The cross section of the red phosphor is a ring, and a layer of reflective material is provided on the lower surface of the red phosphor, wherein the reflective material comprises metal. The yellow fluorescent sheet is located directly below the empty portion in the middle of the ring, and the yellow fluorescent sheet and the red phosphor are fixed as one body. The yellow fluorescent sheet and the red phosphor are both fixed in the lampshade, and the lampshade is fixed to the pole tower via the fixed end.

[0007] When the tower is in a vertical state, the blue laser shines on the yellow phosphor and emits white light; when the tower is in a tilted state, the blue laser shines on the red phosphor and emits red light as a warning.

[0008] The laser module is closed during the day and turned on at night, which makes it easy to observe the tilt warning signal while taking into account lighting.

[0009] The specific working principle of the device is as follows: when the tower is in a vertical state, the device is placed vertically, the yellow fluorescent sheet is located directly below the blue light, and the blue laser shines on the yellow fluorescent sheet to emit white light; when the tower is in a tilted state, the device tilts, and the red phosphor also tilts accordingly. The position of the red phosphor changes to directly below the blue light, and the blue laser shines on the red phosphor to emit red light as a warning. The yellow fluorescent sheet and the red phosphor are both made of fluorescent powder, which is an existing mature technology and is easy to prepare.

[0010] The beneficial effects are as follows:

[0011] When the tower is in a vertical state, the device emits white light; when the tower is in a tilted state, the device emits red light as a warning to facilitate timely inspection by staff and the public.

[0012] When the tower is in a vertical state, the yellow fluorescent sheet will emit white light diffusely reflected in all directions. The reflective material can prevent the white light from entering the red phosphor and generating red light, ensuring that the tower will not emit red light when it is vertical. It will only emit red light when it is tilted. The warning signal is very obvious.

[0013] When the yellow fluorescent sheet emits white light, it can indicate that the tower is in a vertical state and provide lighting. It can also be used as a sign of the tower at night to prevent pedestrians and vehicles from accidentally hitting the tower, achieving multiple goals at one stroke.

[0014] The laser module is turned off during the day and turned on at night. Firstly, it can save electricity, and the tilt warning signal is more obvious at night. Secondly, since the tilt of the tower is usually a slow process that accumulates day by day, only issuing the tilt warning signal at night is sufficient to monitor the tilt change process and issue the warning signal in time.

[0015] It also includes a battery module and a solar module. The battery module supplies power to the laser module, and the solar module charges the battery module.

[0016] The beneficial effect is that the solar module not only solves the power supply problem of the blue laser module, but also solves the night lighting problem. It is fully utilized, energy-saving and environmentally friendly. At the same time, compared with ordinary light sources such as LED, laser lighting has high luminous efficiency, consumes less energy at the same brightness, and can extend the night lighting time.

[0017] The yellow fluorescent sheet has a V-shaped vertical section, and the width of the middle of the V is less than 1 / 2 of the upper end, that is, both left and right sides of the V are concave inwards.

[0018] The beneficial effects are as follows: first, the V-shaped vertical cross-section of the yellow fluorescent sheet has the following effects: first, the V-shaped has a certain height difference, that is, the yellow fluorescent sheet is not a plane, the light it emits is more three-dimensional, and its luminous angle can exceed 180 degrees, more like a light bulb, which can be easily observed from all directions and can better achieve illumination; second, the intensity of the laser emitted by the laser module is Gaussian distributed from the edge to the center. At the same time, the left and right sides of the V-shaped are concave inward, that is, the area of ​​the yellow fluorescent sheet corresponding to the middle per unit area in the laser direction is larger than that at the edge (specifically, Mathematically, the absolute value of the slope of the curves on the left and right sides of the V-shape can be calculated. The absolute value of the slope is positively correlated with the area of ​​the yellow fluorescent sheet, increasing from the edge to the center. The sheet also exhibits a Gaussian distribution. The fluorescent sheet in the middle can radiate laser light, with the light radiating more to the left and right sides of the V-shape, thereby weakening the luminous intensity in the middle, making the white light emitted from the yellow fluorescent sheet uniform. At the same time, the blue laser in the middle can be fully converted into white light, achieving better illumination. In addition, the conversion load in the middle of the yellow fluorescent sheet is uniform, extending its service life. Fluorescent sheets are made by applying fluorescent powder to a glass sheet. In the prior art, planar fluorescent sheets are commonly used, and their luminous angle cannot exceed 180 degrees. They are usually used for small-angle lighting such as flashlights and car lights, and do not have the three-dimensional, large-angle luminous effect of the present invention.

[0019] The inner diameter of the circular ring is larger than the diameter of the blue laser spot; the transverse width of the yellow fluorescent sheet is equal to the inner diameter of the circular ring.

[0020] The beneficial effect is that when the inner diameter of the ring is larger than the diameter of the blue laser spot, the blue laser will not irradiate the red phosphor within a certain tilt angle of the tower, so a certain tilt angle is allowed, which is in line with the actual situation (if the inner diameter of the ring is equal to the diameter of the blue laser spot, then as long as there is a slight tilt, the blue laser will irradiate the red phosphor and emit red light, which is too strict and does not conform to the actual situation); the lateral width of the yellow fluorescent sheet is equal to the inner diameter of the ring, that is, there is no lateral gap between the yellow fluorescent sheet and the red phosphor, and the blue laser will at least enter one of the above-mentioned two, avoiding the laser being directly emitted downward and affecting pedestrians on the ground. At the same time, the laser can be fully used for lighting (of course, the blue laser may also be divided into two parts and simultaneously enter the yellow fluorescent sheet and the red phosphor, but in any case, as long as it enters the red phosphor and produces red light, a tilt warning signal is issued).

[0021] The red phosphor is formed by mixing a transparent material and red phosphor powder, and the transparent material includes transparent glass and transparent plastic.

[0022] The beneficial effect is that the red phosphor is not a fluorescent sheet. It has a certain thickness, allowing blue light to fully contact the red phosphor, producing sufficient red light. At the same time, it has more uniform diffuse reflection in all directions, and the light it emits is more three-dimensional. The light emission angle can exceed 180 degrees, more like a light bulb, which can be easily observed from all directions and provides better illumination. In the prior art, flat fluorescent sheets are generally used. The light emission angle cannot exceed 180 degrees and does not have the three-dimensional wide-angle light effect of the present invention.

[0023] The connection between the laser module and the lampshade includes a spherical shell and a sphere. The sphere is located in the spherical shell. The sphere and the spherical shell share a common center. The spherical shell is fixedly connected to the lampshade. The lower end of the sphere is fixedly connected to the laser module through a hanging rod. The lower end of the spherical shell is open to facilitate the rotation of the sphere in the spherical shell when tilted.

[0024] The beneficial effect is that the sphere and the spherical shell share the same center, and the sphere can rotate in all directions within the spherical shell. At the same time, this rigid connection ensures the stability of the position of the laser module, and the direction of the laser is always vertically downward. If the rope suspension of the existing technology is used, it is easy for the laser module to tilt due to a slight error in the suspension point, causing the laser direction to deviate from the vertical direction. Furthermore, the lower end portion of the spherical shell is open, and the size of the lower end portion is limited, allowing the sphere to rotate within the spherical shell only to a certain angle. Because if the sphere rotates too much within the spherical shell, it will exceed the range of the red phosphor that can be irradiated by the laser, resulting in the inability to emit red light. That is, when the tilt angle is too large, red light cannot be emitted, and effective warning cannot be given. Limiting the rotation angle range of the sphere within the spherical shell can avoid the above problems.

[0025] Usage of the device:

[0026] During installation, ensure that the tower is in a vertical state and the device is fixed vertically on the tower;

[0027] When the tower is in a vertical state, the blue laser module is turned on at night, and the blue laser shines on the yellow phosphor sheet to emit white light for lighting;

[0028] When the tower is in a tilted state, the device tilts and the red phosphor also tilts. The position of the red phosphor changes to be just below the blue laser. The blue laser shines on the red phosphor and emits red light as a warning.

[0029] The beneficial effects are as follows: the method has the beneficial effects of the device, and most importantly, when the tower is in a tilted state, the device emits a red light, and the early warning signal is very obvious. The general public can also discover it in time and provide effective clues, so as to achieve collective prevention and control.

[0030] A tower tilt warning device, characterized by comprising a blue laser module, a yellow phosphor, a red phosphor, a lampshade, and a fixed end. The blue laser module is freely suspended in the lampshade, and the blue laser it emits is vertically downward. When the device is placed vertically, the yellow phosphor is located directly below the blue laser.

[0031] The vertical section of the yellow phosphor is in the shape of an inverted convex character, and the four corners below the middle of the inverted convex character are rounded. The yellow phosphor is made of a mixture of transparent material and yellow phosphor powder. The transparent material includes transparent glass, transparent plastic,

[0032] The cross section of the red phosphor is a ring, and a layer of reflective material is provided on the lower surface of the red phosphor, wherein the reflective material comprises metal. The yellow phosphor is located directly below the empty portion in the middle of the ring, and the yellow phosphor and the red phosphor are fixed as one body, and both the yellow phosphor and the red phosphor are fixed in the lampshade, and the lampshade is fixed to the pole tower via the fixed end.

[0034] The laser module is closed during the day and turned on at night, which makes it easy to observe the tilt warning signal while taking into account lighting.

[0035] The beneficial effects are as follows:

[0036] The vertical cross-section of the yellow phosphor is in the shape of an inverted convex character as a whole, which has the following effects: first, the inverted convex character has a certain height difference between the upper and lower parts, that is, the yellow phosphor is not a plane, and the light it emits is more three-dimensional, and its luminous angle can exceed 180 degrees, which is more like a light bulb, which can be easily observed from all directions and can better identify the tower; secondly, the intensity of the laser emitted by the current laser module is Gaussian distributed from the edge to the center. At the same time, the bottom of the inverted convex character is convex downward, that is, the thickness of the yellow phosphor corresponding to the middle in the laser direction is greater than that of the edge, and is also Gaussian distributed. The yellow phosphor in the middle part can further diverge the laser, and the light is more divergent to the left and right sides of the yellow phosphor, thereby weakening the middle luminous intensity, making the white light emitted from the yellow phosphor very uniform. At the same time, the blue laser in the middle can be fully converted into white light to better achieve lighting. In addition, the conversion load in the middle part of the yellow fluorescent sheet is uniform, and its service life is extended.

[0037] When the tower is in a vertical state, the device emits white light; when the tower is in a tilted state, the device emits red light as a warning to facilitate timely inspection by staff and the public.

[0038] When the tower is in a vertical state, the yellow phosphor will emit white light diffusely reflected in all directions. The reflective material can prevent the white light from entering the red phosphor and generating red light, ensuring that the tower will not emit red light when it is vertical. It will only emit red light when it is tilted. The warning signal is very obvious.
