Description

Technical Field

[0001] The present invention relates to the technical field of signal lights, and particularly to a marine navigation signal light with anti-freezing and anti-fogging functions. Background Art

[0002] When ocean-going ships are sailing at sea, especially in cold seasons or foggy days, it is necessary to ensure that the signal lights can work properly to ensure navigation safety. Inland ships also need reliable signal lights to identify their positions and directions in winter or seasons with higher humidity.

[0003] Currently, in a low-temperature environment, ice will form on the outer wall of the lamp cover, which will not only cause the brightness of the signal light to decrease, but may also affect the structural integrity of the lamp cover, thus affecting the light transmittance of the lamp cover. In a high-humidity environment, fog will form on the outer wall of the lamp cover. Even if it is externally sealed, internal moisture will still cause fogging, resulting in the signal light being blurred, affecting the recognition distance, and also affecting the light transmittance. However, ordinary signal lights only have basic lighting functions and no additional protective measures. Although some signal lights are equipped with heating elements inside to prevent icing by heating, the heating elements need to be continuously powered, consuming a large amount of electricity. In addition, the heat of the lamp wick is not effectively utilized, resulting in energy waste. There are also some sealed signal lights that prevent external moisture from entering through a sealed design, but they cannot completely avoid the problems of internal icing or fogging, and the sealing will cause the heat generated when the lamp wick works to be unable to escape, thus burning out the lamp wick.

[0004] Based on the above problems, the present invention proposes a marine navigation signal light with anti-freezing and anti-fogging functions. Summary of the Invention

[0005] In order to overcome the disadvantages described in the above background art, the present invention provides a marine navigation signal light with anti-freezing and anti-fogging functions.

[0006] A marine navigation signal light with anti-freezing and anti-fogging functions includes a base, the base is fixedly connected with a fixing frame, the fixing frame is fixedly connected with a heat collecting ring, a lamp wick is fixedly connected between the fixing frame and the heat collecting ring, an air passage is left between the fixing frame and the heat collecting ring, the fixing frame is fixedly connected with a lamp cover, the lamp wick is located inside the lamp cover, a first fan is installed on one side of the lamp cover far from the heat collecting ring, a heat conducting frame for guiding the hot air flow inside the lamp cover to the outer wall is fixedly connected to the top of the lamp cover, and a pressure increasing ring for accelerating the hot air flow is fixedly connected to the bottom of the heat conducting frame.

[0007] As a further preferred solution, the heat conducting frame is provided with an annular groove.

[0008] As a further preferred solution, the diameter of the side of the pressure increasing ring close to the heat conducting frame is larger than the diameter of the side of the pressure increasing ring far from the heat conducting frame.

[0009] As a further preferred solution, it further includes a storage rack for storing a thermal expansion agent. The storage rack is fixedly connected to the middle of the fixed rack. An expansion rack is arranged inside the storage rack. The expansion part of the expansion rack is slidably connected to the storage rack. The expansion end of the expansion rack is fixedly connected with an opening and closing plate. The fixed rack is provided with an annular air inlet. The opening and closing plate is used to adjust the size of the air inlet.

[0010] As a further preferred solution, the thermal expansion agent inside the storage rack is set as ethyl acetate.

[0011] As a further preferred solution, it further includes a second fan. The second fan is rotatably connected to the side of the heat conduction rack close to the first fan through a rotating shaft. A cleaning brush is fixedly connected to the rotating shaft of the second fan. The cleaning brush contacts the outer side surface of the lamp cover.

[0012] As a further preferred solution, it further includes expansion rods symmetrically distributed along the heat conduction rack. A bearing rack is fixedly connected between the ends of the symmetrically distributed expansion rods. The bearing rack is slidably connected to the heat conduction rack. A first rubber ring is fixedly connected to the rotating shaft of the second fan. A second rubber ring is fixedly connected to the bearing rack. The second rubber ring contacts the second rubber ring and is in frictional cooperation with each other.

[0013] As a further preferred solution, the heat conduction rack is provided with drain ports distributed at equal intervals. The bearing rack is provided with a drainage port.

[0014] As a further preferred solution, the drain port is set as an arc shape, and the drainage port is set as a circular shape with a small aperture.

[0015] As a further preferred solution, it further includes a warning ring. The warning ring is fixedly connected to the fixed rack. The warning ring is made of a reflective material.

[0016] The beneficial effects are as follows: In an environment with a relatively low temperature or humidity, this signal lamp automatically partially closes the air inlet through the opening and closing plate, reducing the opening of the air inlet, thereby reducing the entry of cold air. At the same time, the heat generated when the internal lamp wick works is gathered by the heat collecting ring and then accelerated to flow to the outer wall of the lamp cover successively through the gap between the lamp cover and the heat conduction rack and the gap between the lamp cover and the pressure increasing ring. While dissipating heat, it not only prevents freezing or condensation of water droplets on the outer wall of the lamp cover, but also saves heat sources. At the same time, the accelerated hot air flow can blow down the water flow on the cover wall, accelerating the downward flow of the water flow and ensuring the light transmittance of the lamp cover.

[0017] This signal lamp uses the high-speed hot air flow to drive the second fan to rotate, thereby driving the cleaning brush to rotate, so that the cleaning brush rotates along the outer wall of the lamp cover. In this way, the water droplets melted on the outer wall of the lamp cover are removed in time, avoiding the influence of water droplets on the light transmittance.

[0018] This signal lamp utilizes the frictional force between the first rubber ring and the second rubber ring to slow down the rotation speed of the cleaning brush. In this way, the effect of slowing down the rotation speed is achieved, avoiding the situation that the cleaning brush rotates too fast, resulting in short-term light spots or shadows in the light beam of the signal lamp, which briefly affects the visibility of the signal lamp, and thus causing the signal lamp to flash continuously, affecting the function of the signal lamp to guide the navigation of ships.

[0019] This signal lamp utilizes rainwater or melted snow water to cause the first rubber ring and the second rubber ring to automatically separate in rainy or snowy weather, thereby accelerating the rotation speed of the cleaning brush. In this way, the effect of accelerating the rotation speed is achieved, avoiding the accumulation of rainwater or snowflakes on the outer wall of the lamp cover, and thus avoiding affecting the light transmittance of the lamp cover.

[0020] This signal lamp uses the warning ring as an alternative solution, so that when the signal lamp is powered off or damaged, the crew on the ship can irradiate the warning ring with a flashlight, and judge the position of the signal lamp through the reflective effect of the warning ring, thereby determining the direction of navigation.

Detailed implementation manners

[0031] The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which preferred embodiments of the present invention are shown. However, the present invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness and fully convey the scope of the present invention to those skilled in the art.

[0032] Embodiment 1: A marine navigation signal lamp with antifreeze and anti - fog functions, as Figures 1 - 3 shown, includes a base 101. A fixing frame 102 is fixedly connected to the top of the base 101. A heat collecting ring 103 is fixedly connected to the upper side inside the fixing frame 102. A wick 104 is fixedly connected to the middle between the fixing frame 102 and the heat collecting ring 103. An air channel 1041 is left on the side between the fixing frame 102 and the heat collecting ring 103. A lampshade 105 is fixedly connected to the top of the fixing frame 102. The wick 104 is located inside the lampshade 105. A first fan 106 is installed on the upper side inside the lampshade 105. The switch of the signal lamp is electrically connected to the first fan 106 through a control module. A heat conducting frame 107 is fixedly connected to the top of the lampshade 105. The heat conducting frame 107 is provided with an annular groove for guiding the hot air flow inside the lampshade 105 to the outer wall of the lampshade 105. A pressurizing ring 108 is fixedly connected to the bottom of the heat conducting frame 107. The pressurizing ring 108 is used to accelerate the hot air flow at the groove of the heat conducting frame 107, so that the hot air flow is quickly sprayed onto the outer wall of the lampshade 105. The caliber of the top of the pressurizing ring 108 is larger than that of the bottom of the pressurizing ring 108.

[0033] As Figure 4 and Figure 5 shown, it further includes a storage rack 201 for storing ethyl acetate. The storage rack 201 is fixedly connected to the middle of the fixing frame 102. The thermal expander inside the storage rack 201 is set as ethyl acetate. A telescopic frame 204 is arranged inside the storage rack 201. The telescopic part of the telescopic frame 204 is slidably connected to the storage rack 201. The telescopic end of the telescopic frame 204 is fixedly connected to an opening and closing plate 202. The fixing frame 102 is provided with an annular air inlet 203. Moving the opening and closing plate 202 upward can enlarge the air inlet 203, and moving the opening and closing plate 202 downward can also enlarge the air inlet 203.

[0034] After the light is turned on, the switch of the signal lamp controls the automatic start of the first fan 106 through the control module, so as to conduct the heat generated by the working state of the internal lamp core 104 upward. The heat generated by the working state of the lamp core 104 is gathered by the heat collecting ring 103. The air inlet 203 and the air channel 1041 ensure the circulating flow of air. In a normal temperature environment, the air inlet 203 is in a fully ventilated state, which is conducive to the dissipation of internal heat. In an environment with relatively low temperature or humidity, the ethyl acetate in the storage rack 201 shrinks, causing the opening and closing plate 202 to automatically move downward, and the telescopic frame 204 to contract until the air inlet 203 is partially closed by the opening and closing plate 202, reducing the opening of the air inlet 203, thereby reducing the entry of cold air. At the same time, the internal hot air flow sequentially passes through the gaps between the lamp cover 105 and the heat conduction rack 107, and between the lamp cover 105 and the pressurizing ring 108 and is accelerated to flow to the outer wall of the lamp cover 105. While dissipating heat, it prevents freezing or condensation of water mist on the outer wall of the lamp cover 105, saves heat sources, and at the same time, the accelerated hot air flow can blow the water flow on the cover wall downward, accelerating the downward flow of the water flow and ensuring the light transmittance of the lamp cover 105. When the temperature or humidity returns to normal, the ethyl acetate in the storage rack 201 expands thermally, causing the telescopic frame 204 to elongate and the opening and closing plate 202 to automatically move upward until the air inlet 203 is fully opened. After the light is turned off, the switch of the signal lamp controls the automatic shutdown of the first fan 106 through the control module.

[0035] Example 2: On the basis of Example 1, as Figure 6 shown, it further includes a second fan 301. The second fan 301 is rotationally connected to the middle of the heat conduction rack 107 through a rotating shaft. The second fan 301 is located above the first fan 106. A cleaning brush 302 is fixedly connected to the rotating shaft of the second fan 301. The cleaning brush 302 contacts the outer side surface of the lamp cover 105.

[0036] When the hot air inside is blown out by the first fan 106, the high-speed air flow drives the second fan 301 to rotate, thereby driving the cleaning brush 302 to rotate, so that the cleaning brush 302 rotates along the outer wall of the lamp cover 105. In this way, the water droplets melted on the outer wall of the lamp cover 105 are removed in time, avoiding the influence of water droplets on the light transmittance.

[0037] As Figure 7 and Figure 8As shown in the figure, it further includes telescopic rods 401 symmetrically distributed on the left and right along the heat conduction frame 107. A bearing frame 402 is fixedly connected between the ends of the telescopic rods 401 symmetrically distributed on the left and right. The bearing frame 402 is used to bear rainwater or snowflakes. Drainage ports 403 are arranged at equal intervals around the periphery of the heat conduction frame 107. The drainage ports 403 are set in an arc shape. The bearing frame 402 is slidably connected to the inner wall of the heat conduction frame 107. A first rubber ring 404 is fixedly connected to the upper part of the rotating shaft of the second fan 301. A second rubber ring 405 is fixedly connected to the middle of the bearing frame 402. The second rubber ring 405 is in contact with the second rubber ring 405 and is in frictional cooperation with each other. A drain port 406 is opened at an eccentric position at the bottom of the bearing frame 402. The drain port 406 is set as a circular shape with a small aperture for slowly discharging rainwater or melted snow water.

[0038] In the above process, since the high-speed air flow drives the second fan 301 to rotate, the cleaning brush 302 rotates at a relatively high speed, which may generate short-term light spots or shadows in the light beam of the signal lamp, that is, it may temporarily affect the visibility of the signal lamp, resulting in the signal lamp flashing continuously, affecting the function of the signal lamp to guide the ship's navigation. Therefore, it is necessary to slow down the rotation speed through the following operations. Specifically: when the second fan 301 rotates, it drives the first rubber ring 404 to rotate. Under the frictional force of the second rubber ring 405, the rotation speed of the second fan 301 slows down, so that the rotation speed of the cleaning brush 302 slows down. In this way, the effect of slowing down the rotation speed is achieved.

[0039] In rainy or snowy weather, if the cleaning brush 302 still rotates at a relatively slow speed, rainwater or snowflakes are likely to accumulate on the outer wall of the lamp cover 105, thus affecting the light transmission of the lamp cover 105. At this time, the high rotation speed should be restored. Specifically: rainwater or snowflakes will accumulate on the top of the bearing frame 402. Affected by the increase in gravity caused by the accumulation, the bearing frame 402 slides downward, the telescopic rod 401 is compressed, and the second rubber ring 405 moves downward with the bearing frame 402 until it disengages from the first rubber ring 404. At this time, without the influence of the frictional force, the rotation speed of the second fan 301 increases, so that the rotation speed of the cleaning brush 302 increases. In this way, the effect of increasing the rotation speed is achieved.

[0040] Rainwater or melted snow water will slowly flow downward through the drain port 406 to the drainage port 403 for slow discharge. In this way, subsequent water accumulation in the bearing frame 402 is avoided. When the water in the bearing frame 402 is emptied, the telescopic rod 401 is fully reset and drives the bearing frame 402 to move upward, thereby driving the second rubber ring 405 to move upward until the second rubber ring 405 contacts the first rubber ring 404.

[0041] Embodiment 3: On the basis of Embodiment 2, as Figure 9As shown, it further includes a warning ring 501. The warning ring 501 is fixedly connected to the fixing frame 102. The warning ring 501 is made of a reflective material. When the signal lamp is powered off or damaged, the crew on the ship shines a flashlight on the warning ring 501. Under the reflective effect of the warning ring 501, the position of the signal lamp is judged, and thus the sailing direction is determined. That is, the warning ring 501 serves as an alternative when the signal lamp is powered off or damaged.

[0042] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
