[0005] To this end, the present invention proposes a modular LED explosion-proof lamp to solve the above problems. Summary of the Invention

[0006] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a modular LED explosion-proof lamp.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a modular LED explosion-proof lamp, comprising:

[0008] The explosion-proof lamp housing has a plurality of heat dissipation fins fixedly connected to the outer wall in a circular array, and a light source board and a water cooling plate located directly above the light source board are arranged inside;

[0009] The bottom surface of the water cooling plate contacts the top surface of the light source board, and a water cooling channel is opened in the water cooling plate, and the water cooling channel has a water outlet and a water inlet located on the same side;

[0010] The water inlet pipe and the water outlet pipe are connected to the water inlet and water outlet of the water cooling channel respectively, and are connected to the water circuit of the water pump;

[0011] The bottom end of the light source board is provided with a plurality of lamp bodies distributed along the track of the water cooling channel, and a water cooling groove is provided in the water cooling channel at the position corresponding to the lamp body to increase the heat dissipation area;

[0012] Specifically, in the prior art, during the use of explosion-proof lamps, since the internal space of the explosion-proof lamps is in a closed state, it is difficult for the air inside the explosion-proof lamps to circulate, resulting in the temperature generated by the lamp body being difficult to dissipate in time. The present technical solution can solve the above problem. The specific operation is as follows: when the explosion-proof lamp is started, the water pump is started, so that the cold water in the external condensation tank enters the water cooling channel through the water inlet pipe, and then is discharged into the condensation tank through the drain pipe;

[0013] When cold water circulates in the water cooling channel, it will lower the temperature of the water cooling plate, dissipate heat to the light source board through the water cooling plate, thereby lowering the temperature of the light source board and further lowering the temperature inside the explosion-proof lamp housing;

[0014] Since the lamp body is arranged on the light source board along the track of the water cooling channel, the water cooling plate can cool down the lamp body position, i.e. the heat source position, in time, and a water cooling groove is opened in the water cooling channel at the position corresponding to the lamp body to increase the heat dissipation area, thereby ensuring that the heat source position can be fully cooled, ensuring that the temperature of the light source board is effectively controlled, and preventing the abnormal temperature inside the explosion-proof lamp housing from rising.

[0015] Preferably, it also includes:

[0016] A temperature sensor is provided in the explosion-proof lamp housing and is used to detect the temperature in the explosion-proof lamp housing;

[0017] A controller controls the speed of an impeller in the water pump based on a temperature signal from a temperature sensor to adjust the circulation speed of the cold water in the water cooling channel.

[0018] Specifically, by setting a temperature sensor and a controller, when the circuit output current increases and the brightness of the lamp body is improved, the temperature inside the explosion-proof lamp housing will increase. Based on the temperature signal of the temperature sensor, when the temperature value exceeds a specified threshold, the controller controls the impeller speed in the water pump to increase, thereby increasing the circulation speed of the cold water in the water cooling channel and accelerating the cooling speed of the water cooling plate, so that the temperature of the light source board can be quickly brought up, ensuring that the temperature of the light source board is effectively controlled and preventing the abnormal temperature increase inside the explosion-proof lamp housing;

[0025] The pushing component is based on the temperature signal of the temperature sensor. When the temperature exceeds the specified threshold, the controller starts the pushing component to push several turbines from the receiving tube into the annular water pipe.

[0026] Preferably, the pushing assembly includes:

[0027] an annular explosion-proof housing, the annular explosion-proof housing being fixedly connected to the outer side wall of the annular water pipe, the receiving tube being located inside the annular explosion-proof housing;

[0028] a plurality of magnets, wherein the plurality of magnets are respectively fixedly connected to ends of the turbine;

[0029] A plurality of electromagnets, wherein the plurality of electromagnets are fixedly connected in the annular explosion-proof housing at positions corresponding to the first electromagnet;

[0030] The controller is based on the temperature signal of the temperature sensor. When the temperature exceeds a specified threshold, the controller turns on the current of several electromagnets, causing the electromagnets to generate the same magnetic force as magnets, thereby pushing several turbines from the storage tube into the annular water pipe.

[0031] Preferably, two cleaning plates are symmetrically and slidably connected to both sides of each heat dissipating fin, and brushes are fixedly connected to the side walls of the cleaning plates;

[0032] The reciprocating linear drive assembly is based on the temperature signal of the temperature sensor. When the temperature exceeds the specified threshold, the controller starts the reciprocating linear drive assembly, causing the cleaning plate to move back and forth along the side wall of the heat sink, and clean the dust on the surface of the heat sink with a brush.

[0033] Preferably, the reciprocating linear drive assembly includes:

[0034] A driving roller, the driving roller is sleeved on the outer wall of the sealed bearing and fixedly connected to the sealed bearing, and a driving groove is opened on the surface of the driving roller;

[0036] Preferably, it also includes:

[0037] The power supply housing is fixed on the top of the explosion-proof lamp housing and contains a controller;

[0041] Compared with the prior art, the present invention has the following beneficial effects:

[0042] 1. The present invention provides a water-cooling plate, a water-cooling channel and a water-cooling groove.

[0044] 3. The present invention sets an annular water pipe and a fan. When the temperature exceeds a specified threshold, the controller controls the impeller speed to increase, thereby increasing the circulation speed of the cold water in the water-cooling channel and starting the electromagnet current, so that the electromagnet generates the same magnetic force as the magnet. Under the principle of like charges repelling each other, the turbine slides along the surface of the sealed bearing and enters the annular water pipe. The turbine is driven to rotate by the water flow, and the sealed bearing drives the fan blades to rotate, thereby increasing the air flow between the heat dissipation fins, further reducing the temperature of the explosion-proof lamp housing, and effectively controlling the internal temperature of the explosion-proof lamp housing.

[0045] 4. The present invention provides a cleaning plate and a reciprocating linear drive assembly. During the rotation of the sealed bearing, the driving roller rotates synchronously.

DETAILED DESCRIPTION

[0055] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0056] like Figures 1 to 8 A modular LED explosion-proof light shown includes:

[0057] The explosion-proof lamp housing 1 has a plurality of heat dissipation fins 2 fixedly connected to its outer wall in an annular array, and a light source board 4 and a water cooling plate 5 located directly above the light source board 4 are provided inside;

[0058] The bottom surface of the water-cooling plate 5 contacts the top surface of the light source board 4, and a water-cooling channel 501 is opened in the water-cooling plate 5. The water-cooling channel 501 has a water outlet and a water inlet located on the same side.

[0059] The water inlet pipe 6 and the water outlet pipe 7 are connected to the water inlet and the water outlet of the water cooling channel 501 respectively, and are in communication with the water pump 8;

[0060] At the bottom of the light source board 4, several lamp bodies 401 are distributed along the track of the water cooling channel 501, and water cooling grooves 502 are opened in the water cooling channel 501 at positions corresponding to the lamp bodies 401 to increase the heat dissipation area;

[0061] Specifically, in the prior art, during the use of the explosion-proof lamp, since the internal space of the explosion-proof lamp is in a closed state, it is difficult for the air inside the explosion-proof lamp to circulate, resulting in the temperature generated by the lamp body 401 being difficult to dissipate in time. The present technical solution can solve the above problem. The specific operation is as follows: when the explosion-proof lamp is started, the water pump 8 is started, so that the cold water in the external condensation tank enters the water cooling channel 501 through the water inlet pipe 6, and is then discharged into the condensation tank through the drain pipe;

[0062] When the cold water circulates in the water cooling channel 501, the temperature of the water cooling plate 5 is lowered, and the light source board 4 is dissipated through the water cooling plate 5, thereby lowering the temperature of the light source board 4 and further lowering the temperature inside the explosion-proof lamp housing 1;

[0063] Since the lamp body 401 is arranged on the light source board 4 along the trajectory of the water cooling channel 501, the water cooling plate 5 can cool down the position of the lamp body 401, that is, the heat source position, in time, and a water cooling groove 502 is opened in the water cooling channel 501 at the position corresponding to the lamp body 401 to increase the heat dissipation area, thereby ensuring that the heat source position can be fully cooled, ensuring that the temperature of the light source board 4 is effectively controlled, and preventing the abnormal temperature inside the explosion-proof lamp housing 1 from rising.

[0064] As a further embodiment of the present invention, it also includes:

[0065] The temperature sensor 9 is arranged in the explosion-proof lamp housing 1 and is used to detect the temperature in the explosion-proof lamp housing 1;

[0066] The controller 10 controls the impeller speed of the water pump 8 based on the temperature signal of the temperature sensor 9 to adjust the circulation speed of the cooling water in the water cooling channel 501;

[0067] Specifically, by providing a temperature sensor 9 and a controller 10, when the circuit output current increases and the brightness of the lamp body 401 is increased, the temperature inside the explosion-proof lamp housing 1 will increase. The controller 10 is based on the temperature signal of the temperature sensor 9. When the temperature value exceeds a specified threshold, the controller 10 controls the impeller speed in the water pump 8 to increase, thereby increasing the circulation speed of the cold water in the water-cooling channel 501 and accelerating the cooling speed of the water-cooling plate 5, so that the temperature of the light source board 4 can be quickly brought up, ensuring that the temperature of the light source board 4 is effectively controlled, and preventing the abnormal increase in the temperature inside the explosion-proof lamp housing 1;

[0068] When the temperature value is less than a specified threshold, the controller 10 controls the impeller speed in the water pump 8 to slow down, thereby reducing energy consumption.

[0069] As a further embodiment of the present invention, an annular water pipe 11 is fixedly connected to several heat dissipating fins 2 on the path, one end of the annular water pipe 11 is connected to the end of the water outlet pipe 7, and the other end is connected to the water pump 8;

[0070] Several sealed bearings 13 are rotatably connected in an annular array within the annular water pipe 11. One end of the sealed bearing 13 is provided with a turbine 15 for driving the sealed bearing 13. The other end passes through the annular water pipe 11 and is fixedly connected to a fan 14. The fan 14 is located between the two heat dissipating fins 2.

[0071] Several receiving tubes 12 are fixedly connected to the outer wall of the annular water pipe 11 at positions corresponding to the turbines 15. The turbines 15 are slidably inserted into the chute provided at the end of the sealed bearing 13. A spring 17 is fixedly connected between the turbine 15 and the sealed bearing 13.

[0072] The controller 10 activates the pushing assembly based on the temperature signal of the temperature sensor 9. When the temperature exceeds a specified threshold, the controller 10 pushes the turbines 15 from the receiving tube 12 into the annular water pipe 11.

[0073] The push components include:

[0074] An annular explosion-proof housing 18 is fixedly connected to the outer wall of the annular water pipe 11, and the receiving pipe 12 is located in the annular explosion-proof housing 18;

[0075] Several magnets 16 are fixedly connected to the ends of the turbine 15;

[0076] Several electromagnets 19, wherein the positions of the several electromagnets 19 corresponding to the first electromagnet 19 are fixedly connected in the annular explosion-proof shell;

[0077] Based on the temperature signal from the temperature sensor 9, when the temperature exceeds a specified threshold, the controller 10 switches on the current of the electromagnets 19, causing the electromagnets 19 to generate the same magnetic force as the magnets 16, thereby pushing the turbines 15 from the receiving tube 12 into the annular water pipe 11;

[0078] Specifically, by providing the annular water pipe 11 and the fan 14, when the temperature exceeds a specified threshold, the controller 10 controls the impeller speed to increase, thereby increasing the circulation speed of the cold water in the water-cooling channel 501 and starting the current of the electromagnet 19, so that the electromagnet 19 generates the same magnetic force as the magnet 16. Under the principle of like charges repelling each other, the turbine 15 slides along the surface of the sealed bearing 13 and enters the annular water pipe 11. The turbine 15 is driven to rotate by the water flow, thereby causing the sealed bearing 13 to drive the fan blades to rotate, thereby increasing the air flow between the heat dissipating fins 2, further reducing the temperature of the explosion-proof lamp housing 1, and effectively controlling the internal temperature of the explosion-proof lamp housing 1.

[0079] When the temperature is lower than the specified threshold, the controller 10 controls the impeller speed to slow down while disconnecting the current of the electromagnet 19, causing the electromagnet 19 to lose its magnetic force. Under the action of the spring 17, the turbine 15 enters the storage tube 12, reducing the space occupied by the annular water pipe 11, thereby ensuring the stability of the cold water circulation speed.

[0080] As a further embodiment of the present invention, two cleaning plates 20 are symmetrically and slidably connected to both sides of each heat dissipating fin 2, and a brush 21 is fixedly connected to the side wall of the cleaning plate 20;

[0081] The controller 10 activates the reciprocating linear drive assembly based on the temperature signal of the temperature sensor 9. When the temperature exceeds a specified threshold, the controller 10 causes the cleaning plate 20 to reciprocate along the side wall of the heat dissipating fin 2, and uses the brush 21 to clean the dust on the surface of the heat dissipating fin 2.

[0082] The reciprocating linear drive assembly includes:

[0083] A driving roller 22 is sleeved on the outer wall of the sealed bearing 13 and fixedly connected to the sealed bearing 13. A driving groove 23 is opened on the surface of the driving roller 22;

[0084] An annular sleeve 24 is slidably connected to the surface of the driving roller 22. A sliding pin is fixed in the annular sleeve 24, and the sliding pin is slidably connected to the driving groove 23. The two ends of the annular sleeve 24 are symmetrically fixedly connected to the telescopic frame 25. The cleaning plate 20 is rotatably connected to the end of the telescopic frame 25.

[0085] When the driving roller 22 rotates the annular sleeve 24, under the guidance of the driving groove 23, the cleaning plate 20 moves back and forth along the side wall of the heat dissipating fin 2, and the dust on the surface of the heat dissipating fin 2 is cleaned by the brush 21;

[0086] The driving groove 23 includes a first arcuate groove 2301, a second arcuate groove 2302, a third arcuate groove 2303, and a fourth arcuate groove 2304. The end of the first arcuate groove 2301 is connected to the end of the second arcuate groove 2302, the beginning of the second arcuate groove 2302 is connected to the beginning of the third arcuate groove 2303, the end of the third arcuate groove 2303 is connected to the end of the fourth arcuate groove 2304, and the beginning of the fourth arcuate groove 2304 is connected to the beginning of the first arcuate groove 2301.

[0087] Specifically, by providing a cleaning plate 20 and a reciprocating linear drive assembly, the driving roller 22 rotates synchronously during the rotation of the sealing bearing 13. Under the guidance of the driving groove 23, the sealing sleeve moves back and forth along the driving groove 23. Under the connection of the telescopic frame 25, the cleaning plate 20 moves back and forth along the side wall of the heat dissipating fin 2. The dust on the surface of the heat dissipating fin 2 is cleaned by the brush 21, ensuring that the heat dissipating fin 2 can fully contact with the air, thereby improving the heat dissipation effect of the explosion-proof lamp housing 1.

[0088] At the same time, during the process of cleaning the surface of the heat dissipation fins 2 , the generated dust will be blown away by the fan 14 , so that the dust is kept away from the explosion-proof lamp housing 1 , thereby preventing the dust from falling again and adhering to the heat dissipation fins 2 .

[0089] It should be noted that: grooves are provided on both sides of the heat dissipation fin 2, and the cleaning plate 20 slides in the grooves;

[0090] Several track seats are fixed on the outer side wall of the explosion-proof lamp housing 1, and the annular sleeve 24 is slidably connected to the track seats.

[0091] As a further embodiment of the present invention, the bottom end of the water cooling plate 5 is fixedly connected to a plurality of limit rods 503 of different diameters, and the limit rod 503 at the top end of the power board corresponding to the target position is provided with a slot 402;

[0092] Specifically, by providing the limiting rod 503 and the slot 402 , it is ensured that the plurality of lamp bodies 401 are in contact with the water cooling groove 502 at the target position.

[0093] As a further embodiment of the present invention, it also includes:

[0094] The power supply shell 3 is fixedly connected to the top of the explosion-proof lamp housing 1. The controller 10 is located in the power supply shell 3. The top of the explosion-proof lamp housing 1 is provided with a first connecting groove 101. The bottom of the power supply shell 3 is provided with a second connecting groove 301 at a position corresponding to the connecting groove.

[0095] A clearance groove 504 is provided at the top of the water cooling plate 5 corresponding to the first connecting groove 101;

[0096] Specifically, by providing the clearance groove 504 , the wires in the power supply housing 3 can be connected to the power board through the clearance groove 504 .

[0097] The working principle of the present invention is as follows: when the explosion-proof lamp is started, the water pump 8 is started, so that the cold water in the external condensation tank enters the water cooling channel 501 through the water inlet pipe 6, and then is discharged into the condensation tank through the drain pipe;

[0098] When the cold water circulates in the water cooling channel 501, the temperature of the water cooling plate 5 is lowered, and the light source board 4 is dissipated through the water cooling plate 5, thereby lowering the temperature of the light source board 4 and further lowering the temperature inside the explosion-proof lamp housing 1;

[0099] Since the lamp body 401 is arranged on the light source board 4 along the track of the water cooling channel 501, the water cooling plate 5 can timely cool down the lamp body 401, i.e., the heat source. In addition, a water cooling groove 502 is provided in the water cooling channel 501 at a position corresponding to the lamp body 401, thereby increasing the heat dissipation area, thereby ensuring that the heat source can be sufficiently cooled, ensuring that the temperature of the light source board 4 is effectively controlled, and preventing the abnormal temperature increase inside the explosion-proof lamp housing 1.

[0100] When the temperature value exceeds the specified threshold, the controller 10 controls the impeller speed in the water pump 8 to increase, thereby increasing the circulation speed of the cold water in the water cooling channel 501, accelerating the cooling speed of the water cooling plate 5, so that the temperature of the light source board 4 can be quickly brought up, ensuring that the temperature of the light source board 4 is effectively controlled, and preventing the abnormal temperature rise inside the explosion-proof lamp housing 1;

[0101] When the temperature value is less than a specified threshold, the controller 10 controls the impeller speed in the water pump 8 to slow down, thereby reducing energy consumption.
