Description

Technical Field

[0001] The utility model relates to the technical field of lighting control devices, in particular to a lighting control device with an automatic testing function. Background Art

[0002] Lighting control devices play a vital role in modern living and working environments. Traditional lighting control devices usually have a single function, mainly controlling the on and off of lighting through manual switches, or simply performing timing control according to time settings. However, with the continuous advancement of technology and people's increasing demand for lighting, this traditional control method has been unable to meet actual needs, and most of them are automatic control, such as outdoor street lights.

[0003] In the prior art, the temperature inside the traditional street lamp lighting control device will increase when in use, so heat dissipation is required. The traditional heat dissipation method requires opening a heat dissipation port on the side wall of the control box, but most traditional heat dissipation ports are always kept open, which causes excessive dust to enter and cause damage to the device. Therefore, the utility model proposes a lighting control device with an automatic testing function to solve the above problem. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a lighting control device with an automatic testing function.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A lighting control device with an automatic testing function comprises a control box, a motor is mounted on the inner wall of the control box, a power shaft of the motor is rotatably connected to the inner wall of the control box, two heat dissipation mechanisms for dissipating heat from the motor are arranged in the control box, heat dissipation ports are arranged on both end side walls of the control box, opening and closing mechanisms for opening and closing the heat dissipation ports are arranged on both end side walls of the control box, the opening and closing mechanisms comprise two symmetrically arranged sliding rods slidably connected to the side walls of the control box, and a guard plate is fixedly connected to one end of the two sliding rods located outside the control box.

[0007] Preferably, the heat dissipation mechanism includes two symmetrically arranged electric push rods fixedly connected to the inner wall of the control box, the telescopic ends of the two electric push rods are fixedly connected to fixed blocks, the ends of the fixed blocks are rotatably connected to rotating rods, and fan blades are fixedly sleeved on the rotating rods.

[0008] Preferably, one end of the two sliding rods located on the same side and located in the control box is commonly fixedly connected to a trapezoidal plate, and the two trapezoidal plates cooperate with the two rotating rods.

[0009] Preferably, the ends of the two trapezoidal plates are elastically connected to the inner wall of the control box via two springs, and filters are provided in the two heat dissipation openings.

[0010] Preferably, a second gear is fixedly sleeved on the power shaft of the motor, and a first gear meshing with the second gear is fixedly sleeved on both of the two rotating rods.

[0011] Preferably, a temperature sensor is installed inside the control box, and the temperature sensor is electrically connected to the two electric push rods.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. By setting an opening and closing mechanism, when the temperature inside the control box rises to the set threshold, the telescopic end of the electric push rod extends, pushing the rotating rod to move, squeezing the trapezoidal plate on the same side, so that the sliding rod drives the guard plate to move outward, opening the heat dissipation port to achieve the heat dissipation effect. When the temperature is not reached, the heat dissipation port is in a closed state. The heat dissipation port can be closed when the device is not in use or stopped, reducing the entry of impurities.

[0014] 2. By setting up a heat dissipation mechanism, when the moving rod moves, the rotating rod and the fan blades are driven to move, causing the first gear to engage with the second gear. Through transmission, the rotating rod and the fan blades rotate, which can accelerate the air convection in the control box, thereby improving the heat dissipation effect.

DETAILED DESCRIPTION

[0021] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation of the utility model is described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific implementation disclosed below.

[0022] Reference Figure 1-5 A lighting control device with automatic testing function comprises a control box 1, a motor 9 is mounted on the inner wall of the control box 1, a power shaft 2 of the motor 9 is rotatably connected to the inner wall of the control box 1, and two heat dissipation mechanisms for dissipating heat from the motor 9 are arranged in the control box 1, and the heat dissipation mechanism comprises two symmetrically arranged electric push rods 6 fixedly connected to the inner wall of the control box 1, the telescopic ends of the two electric push rods 6 are fixedly connected to fixed blocks 10, the ends of the fixed blocks 10 are rotatably connected to rotating rods 11, and fan blades 4 are fixedly sleeved on the rotating rods 11, and one end of the two sliding rods 16 located on the same side located in the control box 1 is jointly fixedly connected to a trapezoidal plate 12, the two trapezoidal plates 12 cooperate with the two rotating rods 11, and the fan blades 4 on both sides are axial flow fan blades, and it should be noted that the ends of the two rotating rods 11 close to the trapezoidal plate 12 are circular in design, which can make the process more smooth when squeezing the trapezoidal plate 12.

[0023] In the utility model, heat dissipation ports 14 are provided on both end side walls of the control box 1, and opening and closing mechanisms for opening and closing the heat dissipation ports 14 are provided on both end side walls of the control box 1, and the opening and closing mechanisms include two symmetrically arranged sliding rods 16 slidably connected to the side walls of the control box 1, and one end of the two sliding rods 16 located outside the control box 1 is commonly fixedly connected to a guard plate 3, and the ends of the two trapezoidal plates 12 are elastically connected to the inner wall of the control box 1 by two springs 13, and filters 15 are provided in the two heat dissipation ports 14, and the springs 13 on both sides can assist the trapezoidal plates 12 and the guard plates 3 to reset, and sealing sleeves are provided on the guard plates 3 on both sides, which can improve the sealing effect when the heat dissipation ports 14 are closed, and the filters 15 on both sides can effectively prevent dust from entering the control box 1 and polluting the interior thereof.

[0024] In the utility model, a second gear 8 is fixedly sleeved on the power shaft 2 of the motor 9, and a first gear 5 meshing with the second gear 8 is fixedly sleeved on the two rotating rods 11. A temperature sensor 7 is installed inside the control box 1. The temperature sensor 7 is electrically connected to the two electric push rods 6. The two first gears 5 are respectively meshed with the two sides of the second gear 8, thereby prompting the rotating rods 11 and the fan blades 4 on both sides to rotate in opposite directions, thereby achieving the effect of one fan blade 4 blowing air and the other fan blade 4 taking in air, which can accelerate the air flow and improve the heat dissipation effect.

[0025] When the utility model is used, when the motor 9 is working, the power shaft 2 rotates. When the temperature rises to the set threshold, the temperature sensor 7 works, the electric push rod 6 is started, and the telescopic end of the electric push rod 6 pushes the fixed block 10 to move, thereby pushing the rotating rod 11, the fan blade 4 and the first gear 5 to move. During the movement of the rotating rod 11, the trapezoidal plates 12 on both sides that cooperate with it can be squeezed, so that the two trapezoidal plates 12 move toward both ends, pushing the sliding rod 16 and the guard plate 3 to move toward both ends, opening the heat dissipation port 14, and completing the heat dissipation inside the control box 1. During this process, the first gear 5 is meshed with the second gear 8, and the rotation of the first gear 5 drives the rotating rod 11 and the fan blade 4 to turn, which can accelerate the air convection inside the control box 1, thereby achieving a better heat dissipation effect;

[0026] When the temperature inside the control box 1 drops below the set threshold, the temperature sensor 7 controls the telescopic end of the electric push rod 6 to contract, driving the fixed block 10 and the rotating rod 11 to contract. At this time, the two first gears 5 are separated from the second gear 8, and the rotating rod 11 stops rotating. At the same time, when the rotating rod 11 contracts, the trapezoidal plate 12 is no longer squeezed. Under the action of the spring 13, the trapezoidal plate 12 is reset, driving the sliding rod 16 and the guard plate 3 to reset, thereby blocking the heat dissipation port 14. At this time, the control box 1 is no longer cooled, and the heat dissipation port 14 is prevented from being opened for a long time, resulting in excessive entry of impurities.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
