Description

A ship navigation signal light with anti-freeze and anti-fog functions

Technical Field

The invention relates to the technical field of signal lamps, and in particular to a ship navigation signal lamp with antifreeze and anti-fog functions.

Background Art

When ocean-going vessels are sailing at sea, especially in cold seasons or foggy days, they need to ensure that signal lights can work properly to ensure navigation safety. Inland vessels also need reliable signal lights to indicate their position and direction in winter or seasons with high humidity.

At present, low temperature environment will cause ice to form on the outer wall of the lampshade, which will not only reduce the brightness of the signal light, but also affect the structural integrity of the lampshade, thereby affecting the light transmittance of the lampshade. High humidity environment will cause fogging on the outer wall of the lampshade. Even if the outside is sealed, the internal moisture will cause fogging, making the signal light unclear, 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 to prevent ice from forming, the heating elements need to be powered continuously and consume a lot of electricity. In addition, the heat of the wick is not effectively utilized, which will lead to energy waste. There are also some sealed signal lights that use sealing design to prevent external moisture from entering, but they cannot completely avoid the problem of internal ice or fogging. In addition, the sealing will cause the heat generated by the wick when it is working to be unable to be discharged, thereby burning the wick.

Based on the above problems, the present invention proposes a ship navigation signal light with anti-freezing and anti-fog functions.

Summary of the invention

In order to overcome the shortcomings mentioned in the above background technology, the present invention provides a ship navigation signal light with anti-freezing and anti-fog functions.

A ship navigation signal light with anti-freeze and anti-fog functions, comprising a base, the base is fixedly connected to a fixing frame, the fixing frame is fixedly connected to a heat collecting ring, a wick is fixedly connected between the fixing frame and the heat collecting ring, an air channel is reserved between the fixing frame and the heat collecting ring, the fixing frame is fixedly connected to a lampshade, the wick is located in the lampshade, a first fan is installed on a side of the lampshade away from the heat collecting ring, a heat conducting frame for guiding the hot air flow in the lampshade to the outer wall is fixedly connected to the top of the lampshade, and a booster ring for accelerating the hot air flow is fixedly connected to the bottom of the heat conducting frame.

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

As a further preferred solution, the diameter of the side of the boost ring close to the heat-conducting frame is larger than the diameter of the side of the boost ring away from the heat-conducting frame.

As a further preferred embodiment, a storage rack for storing thermal expansion agent is further included, wherein the storage rack is fixedly connected to the middle of the fixed rack, a telescopic rack is arranged inside the storage rack, a telescopic portion of the telescopic rack is slidably connected to the storage rack, an opening and closing plate is fixedly connected to the telescopic end of the telescopic rack, and the fixed rack is provided with an annular air inlet, and the opening and closing plate is used to adjust the size of the air inlet.

As a further preferred embodiment, the thermal expansion agent in the storage rack is set to ethyl acetate.

As a further preferred solution, a second fan is also included, which is rotatably connected to the side of the heat-conducting frame close to the first fan through a rotating shaft, and a cleaning brush is fixedly connected to the rotating shaft of the second fan, and the cleaning brush contacts the outer side surface of the lampshade.

As a further preferred solution, it also includes telescopic rods symmetrically distributed along the heat-conducting frame, a bearing frame is fixedly connected between the ends of the symmetrically distributed telescopic rods, the bearing frame is slidably connected to the heat-conducting frame, the rotating shaft of the second fan is fixedly connected to a first rubber ring, the bearing frame is fixedly connected to a second rubber ring, the second rubber rings are in contact with each other and frictionally matched with each other.

As a further preferred solution, the heat-conducting frame is provided with drainage ports distributed at equal intervals, and the supporting frame is provided with a water discharge port.

As a further preferred solution, the liquid discharge port is configured to be arc-shaped, and the water discharge port is configured to be circular with a small aperture.

As a further preferred solution, a warning ring is also included, which is fixedly connected to the fixing frame and is made of reflective material.

The beneficial effect is that in an environment with low temperature or humidity, the signal lamp automatically partially closes the air inlet through the opening and closing plate, reduces the opening of the air inlet, and thus reduces the entry of cold air. At the same time, the heat generated by the internal wick when working is gathered by the heat collecting ring and then accelerated to the outer wall of the lampshade through the gap between the lampshade and the heat conducting frame and the gap between the lampshade and the boost ring. While dissipating heat, it prevents freezing or condensation of mist on the outer wall of the lampshade and saves heat source. At the same time, the accelerated hot air flow can blow the water flow on the cover wall downward, accelerate the downward flow of water, and ensure the light transmittance of the lampshade.

The signal lamp utilizes 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 lampshade, thus timely removing the melted water droplets on the outer wall of the lampshade to prevent the water droplets from affecting the light transmittance.

The signal light utilizes the friction between the first rubber ring and the second rubber ring to slow down the rotation speed of the cleaning brush, thereby achieving the effect of slowing down the rotation speed and preventing the cleaning brush from rotating too fast, resulting in a short-term light spot or shadow in the light beam of the signal light, temporarily affecting the visibility of the signal light, thereby causing the signal light to flash continuously, affecting the function of the signal light to guide the navigation of the ship.

The signal lamp utilizes rainwater or melted snow water, so that in rainy and snowy weather, the first rubber ring and the second rubber ring are automatically separated, thereby accelerating the rotation speed of the cleaning brush. In this way, the effect of increasing the rotation speed is achieved, and rainwater or snowflakes are prevented from accumulating on the outer wall of the lampshade, thereby avoiding affecting the light transmittance of the lampshade.

The signal light uses a warning ring as an alternative solution, so that when the signal light is powered off or damaged, the crew on the ship can illuminate the warning ring with a flashlight and determine the position of the signal light through the reflection effect of the warning ring, thereby determining the direction of navigation.

DETAILED DESCRIPTION

The present invention will now be described more fully below with reference to the accompanying drawings, in which currently preferred embodiments of the present invention are shown. However, the present invention may be implemented 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 these embodiments fully convey the scope of the present invention to the skilled person.

Embodiment 1: A ship navigation signal light with antifreeze and anti-fog functions, as shown in FIGS. 1 to 3, comprises 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 inner upper side of 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 in the lampshade 105, and a heat collecting ring 103 is fixedly connected to the inner upper side of the lampshade 105. A first fan 106 is installed, and the switch of the signal light 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, and the heat-conducting frame 107 has an annular groove for conducting the hot air flow in the lampshade 105 to the outer wall of the lampshade 105. A boost ring 108 is fixedly connected to the bottom of the heat-conducting frame 107, and the boost 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, and the diameter of the top of the boost ring 108 is larger than the diameter of the bottom of the boost ring 108.

As shown in Figures 4 and 5, a storage rack 201 for storing ethyl acetate is also included. The storage rack 201 is fixedly connected to the middle of the fixed frame 102. The thermal expansion agent in the storage rack 201 is set to ethyl acetate. A telescopic rack 204 is set in the storage rack 201. The telescopic part of the telescopic rack 204 is slidably connected to the storage rack 201. An opening and closing plate 202 is fixedly connected to the telescopic end of the telescopic rack 204. The fixed frame 102 is provided with a ring-shaped air inlet 203. The opening and closing plate 202 can move upward to enlarge the air inlet 203, and the opening and closing plate 202 can move downward to enlarge the air inlet 203.

After turning on the light, the switch of the signal light controls the first fan 106 to start automatically through the control module, thereby conducting the heat generated by the internal wick 104 in the working state upward, and collecting the heat generated by the wick 104 in the working state through the heat collecting ring 103. The air inlet 203 and the air channel 1041 ensure the circulation of air. Under normal temperature conditions, the air inlet 203 is in a fully ventilated state, which is conducive to the dissipation of internal heat. Under low temperature or humidity conditions, the ethyl acetate in the storage rack 201 shrinks, causing the opening and closing plate 202 to automatically move downward, and the telescopic rack 204 shrinks 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 intake of cold air. At the same time, the internal hot air flow is accelerated to the outer wall of the lampshade 105 through the gap between the lampshade 105 and the heat-conducting frame 107 and the gap between the lampshade 105 and the boost ring 108 in turn. While dissipating heat, it prevents freezing or condensation of mist on the outer wall of the lampshade 105, and saves heat source. At the same time, the accelerated hot air flow can blow the water flow on the cover wall downward, accelerate the downward flow of water, and ensure the light transmittance of the lampshade 105. When the temperature or humidity returns to normal, the ethyl acetate in the storage rack 201 expands, causing the telescopic rack 204 to extend, and the opening and closing plate 202 automatically moves upward until the air inlet 203 is fully opened. After turning off the light, the switch of the signal light controls the first fan 106 to automatically turn off through the control module.

Embodiment 2: Based on Embodiment 1, as shown in FIG6 , a second fan 301 is further included. The second fan 301 is rotatably connected to the middle of the heat conducting frame 107 via 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 , and the cleaning brush 302 contacts the outer side surface of the lampshade 105 .

When the internal hot air is blown out by the first fan 106, the high-speed airflow 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 lampshade 105, so as to timely remove the water droplets on the outer wall of the lampshade 105 to prevent the water droplets from affecting the light transmittance.

As shown in Figures 7 and 8, it also includes telescopic rods 401 symmetrically distributed along the heat-conducting frame 107, and a carrier frame 402 is fixedly connected between the ends of the telescopic rods 401 symmetrically distributed. The carrier frame 402 is used to carry rainwater or snowflakes. The periphery of the heat-conducting frame 107 is provided with drainage ports 403 distributed at equal intervals, and the drainage ports 403 are arranged in an arc shape. The carrier frame 402 is slidably connected to the inner wall of the heat-conducting frame 107, and 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 carrier frame 402. The second rubber rings 405 are in contact with each other and frictionally matched with each other. A drainage port 406 is opened at an eccentric position at the bottom of the carrier frame 402, and the drainage port 406 is arranged in a small-diameter circle for slowly draining rainwater or melted snow water.

In the above process, since the high-speed airflow drives the second fan 301 to rotate, the cleaning brush 302 rotates faster, which may generate a short light spot or shadow in the light beam of the signal light, that is, temporarily affecting the visibility of the signal light, thereby causing the signal light to flash continuously, affecting the function of the signal light to guide the navigation of the ship. 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 friction force of the second rubber ring 405, the rotation speed of the second fan 301 slows down, thereby slowing down the rotation speed of the cleaning brush 302, so as to achieve the effect of slowing down the rotation speed.

In rainy and snowy weather, if the cleaning brush 302 still rotates at a relatively slow speed, rain or snowflakes are easily accumulated on the outer wall of the lampshade 105, thereby affecting the light transmittance of the lampshade 105. At this time, the high speed should be restored. Specifically, rain or snowflakes will accumulate on the top of the supporting frame 402. Under the influence of the increased gravity caused by the accumulation, the supporting frame 402 slides downward, the telescopic rod 401 is compressed, and the second rubber ring 405 moves downward with the supporting frame 402 until it is separated from the first rubber ring 404. At this time, the influence of friction is lost, the speed of the second fan 301 is accelerated, and the speed of the cleaning brush 302 is accelerated, thereby achieving the effect of increasing the speed.

Rainwater or melted snow water will slowly flow downward through the drain port 406 to the drain port 403 for slow discharge, thereby preventing water from accumulating in the subsequent support frame 402. When the accumulated water in the support frame 402 is drained, the telescopic rod 401 is completely reset to drive the support 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.

Embodiment 3: Based on Embodiment 2, as shown in FIG9 , a warning ring 501 is further included. The warning ring 501 is fixedly connected to the fixing frame 102. The warning ring 501 is made of reflective material. When the signal light is powered off or damaged, the crew on the ship illuminates the warning ring 501 with a flashlight, and determines the position of the signal light by the reflective effect of the warning ring 501, thereby determining the direction of navigation. That is, the warning ring 501 serves as an alternative solution when the signal light is powered off or damaged.

The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
