Description

Technical Field

[0001] This utility model relates to the field of lighting control device technology, specifically a solar photovoltaic lighting control device. Background Technology

[0002] The solar photovoltaic lighting control box is a DC-type independent photovoltaic power generation control system, representing a green, efficient, and intelligent outdoor lighting solution. The control box integrates a battery, controller, communication module, battery management system, and heating module, and features various functions including control system charging and discharging, constant current, light and time control, battery low-voltage and over-voltage protection, load protection, over-temperature protection, and low-temperature heating.

[0003] An existing patent (publication number: CN222531158U) discloses a lighting electrical control box with enhanced heat dissipation, belonging to the field of control boxes. It includes a control box body, an iron mounting plate fixedly installed inside the control box body, and a heat dissipation device fixedly installed on the inner wall of the control box body. The heat dissipation device consists of a frame, a cooling fan, and an air guide shell. The cooling fan is fixedly installed inside the frame, the air guide shell is fixedly installed at the inner end of the frame, and an air guide pipe is fixedly inserted into the air guide shell.

[0004] Although this application incorporates a heat dissipation device with ductwork, allowing the intake duct to be placed close to heat-generating electrical components, thus enabling rapid heat dissipation and reducing heat buildup in the control box, and ultimately ensuring effective cooling even in areas far from the cooling fan, avoiding heat loss, the application lacks protective measures for the heat dissipation device. In humid environments or rainy weather, moisture may seep into the control box, causing internal control equipment to become damp, malfunction, or even short-circuit. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a solar photovoltaic lighting control device that solves the problem that moisture may seep into the control box in humid environments or rainy days, causing the control equipment inside the control box to become damp, malfunction, or even short-circuit.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a solar photovoltaic lighting control device, comprising a housing and a heat exchange component and an adjustment component installed inside the housing, wherein the heat exchange component is used to dissipate heat from the inside of the housing.

[0007] The heat exchange assembly includes a heat exchange plate fixed inside the heat exchange cavity of the housing, which divides the heat exchange cavity into an outer cavity and an inner cavity. Heat dissipation fins are fixed on the outer side of the heat exchange plate and are disposed inside the outer cavity. A second fan is installed on the side of the housing, and the air outlet direction of the second fan corresponds to that of the outer cavity. A placement chamber is provided inside the housing, and a first fan is installed on the inner wall of the placement chamber, with the air outlet direction of the first fan corresponding to that of the inner cavity.

[0008] Through the above scheme, the heat exchange plate and heat dissipation fins work together to increase the heat dissipation area and improve the heat exchange efficiency; the first fan and the second fan control the airflow in the inner cavity and the outer cavity respectively, realize independent regulation of internal and external circulation, avoid the direct entry of external humid air into the equipment compartment, and effectively prevent the internal components from getting damp.

[0009] Furthermore, the second fan is located on the other side of the housing relative to the first fan, and the first fan and the second fan have opposite air outlet directions. The housing is provided with a filter plate on the other side relative to the second fan. The housing is provided with a first ventilation opening and a second ventilation opening on both sides. The filter plate and the second fan are both embedded inside the second ventilation opening. The second fan, the outer cavity and the filter plate constitute a first air duct, and the first air duct is connected to the outside.

[0010] Furthermore, the first vent is located on the opposite side from the second vent, and the second fan is embedded inside the first vent. The first fan, the inner cavity, and the first vent constitute a second air duct. The second air duct is connected to the placement chamber, and the first air duct exchanges heat with the second air duct through a heat exchange plate and heat dissipation fins.

[0011] The above solution uses a filter plate to block dust from entering, preventing dust accumulation on the heat exchange plate surface and affecting heat dissipation. The first and second air ducts are physically isolated by the heat exchange plate to prevent moisture from seeping into the inner cavity. The second air duct ensures air circulation inside the equipment compartment, while the first and second fans provide forced convection, allowing the second air duct to exchange heat indirectly with the first air duct through the heat exchange plate. This ensures heat dissipation efficiency, isolates external moisture, and further avoids the risk of short circuits.

[0012] Furthermore, the heat exchange assembly also includes a baffle. The housing has a movable chamber inside, and the baffle passes through the movable chamber. A connecting rod is rotatably connected to the lower surface of the baffle. An electric actuator is fixed to the inner wall of the movable chamber. The output end of the electric actuator is rotatably connected to the connecting rod. The baffle moves inside the movable chamber through the electric actuator and the connecting rod. There are two sets of the baffle, the electric actuator, and the connecting rod, which are respectively arranged inside the first ventilation opening and the second ventilation opening. The first ventilation opening and the second ventilation opening are separated by the baffle.

[0013] With the above scheme, under normal operating conditions, the baffle is closed to maintain a sealed internal circulation state and ensure protection. When the temperature inside the chamber is too high and heat dissipation needs to be enhanced, the controller controls the electric push rod to retract the baffle, so that the second fan and the first fan can directly introduce cold air from the outside into the placement chamber for forced air cooling, thereby achieving rapid cooling and balancing safety under normal conditions with heat dissipation efficiency under extreme operating conditions.

[0014] Furthermore, the adjustment assembly includes a knob disposed on one side of the housing, a bidirectional threaded rod fixed to the side of the knob, a transmission chamber opened inside the housing, the other end of the bidirectional threaded rod being rotatably connected to the inner wall of the transmission chamber, a threaded cap being threadedly connected to the surface of the bidirectional threaded rod, a connecting block being fixed to the upper surface of the threaded cap, and a mounting plate being fixed to the upper surface of the connecting block.

[0015] The above solution allows for the simultaneous adjustment of the positions of the mounting plates on both sides by rotating a knob to drive the bidirectional threaded rod. This eliminates the need for tools and allows for the adaptation to various mounting brackets or bases of different sizes, thus improving the ease of installation and versatility of the equipment.

[0016] Furthermore, there are two sets of the threaded cap, connecting block, and mounting plate, which are symmetrically arranged at both ends of the bidirectional threaded rod. The upper surface of the housing is provided with a movable groove, the transmission chamber is connected to the movable groove, the connecting block passes through the movable groove, and the side of the housing is also provided with a drainage groove, which is connected to the transmission chamber. The surfaces of the bidirectional threaded rod, connecting block, and threaded cap are all coated with a waterproof coating.

[0017] Through the above solution, the drainage trough can promptly discharge the liquid entering the transmission chamber, preventing its accumulation and causing corrosion of the internal mechanism. At the same time, the waterproof coating applied to the surface of the bidirectional threaded rod, threaded cap, and connecting block further enhances the overall corrosion resistance and moisture resistance, ensuring the long-term reliability and service life of the adjustment mechanism in humid environments.

[0018] Furthermore, the enclosure contains a battery, a controller, a communication module, a battery management system, and a heating module, and a door is installed on the front of the enclosure.

[0019] The above solution integrates core functional units such as batteries, controllers, and communication modules inside the enclosure. The controller intelligently coordinates the operation of the fan, electric actuator, and heating module, achieving not only intelligent heat dissipation and thermal management but also forming a complete, efficient, reliable, and remotely monitored independent photovoltaic lighting control system, thereby improving the overall performance and intelligence level of the entire solar lighting system.

[0020] Compared with the prior art, the technical solution of this utility model has the following beneficial effects: This solar photovoltaic lighting control device solves the problem of moisture, humidity, and dust easily entering the cabinet through the heat exchange openings in traditional heat dissipation solutions by constructing a completely isolated internal and external circulation heat exchange method using heat exchange components. This greatly reduces the risk of the equipment getting damp, malfunctioning, or short-circuiting in harsh environments such as humid and rainy conditions, and improves the long-term operational reliability and service life of the system. At the same time, by controlling the position of the baffle, the heat dissipation mode can be switched. The closed internal circulation mode ensures both heat dissipation and protection. In extreme high-temperature conditions, it switches to a direct-flow strong cooling mode for rapid cooling, avoiding performance degradation or damage to components due to overheating.

Detailed Implementation

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] Please see Figure 1 , Figure 2 and Figure 3This embodiment of a solar photovoltaic lighting control device includes a housing 1 and a heat exchange component 2 and an adjustment component 3 installed inside the housing 1. The heat exchange component 2 is used to dissipate heat from the inside of the housing 1. The heat exchange method constructed by the heat exchange component 2, which completely isolates the internal and external circulation, solves the problem that moisture, humidity, and dust can easily enter the inside of the housing 1 through the heat dissipation openings in traditional heat dissipation schemes. This greatly reduces the risk of the equipment getting damp, malfunctioning, or short-circuiting in harsh environments such as humid and rainy conditions, and improves the long-term operational reliability and service life of the system. At the same time, by controlling the position of the baffle 210, the heat dissipation mode can be switched. The closed internal circulation mode ensures both heat dissipation and protection. In extreme high-temperature conditions, the device can switch to a direct-flow strong cooling mode for rapid cooling, avoiding performance degradation or damage to components due to overheating.

[0025] The heat exchange assembly 2 includes a heat exchange plate 201 fixed inside the heat exchange cavity of the housing 1. The heat exchange plate 201 divides the heat exchange cavity into an outer cavity 202 and an inner cavity 203. Heat dissipation fins 204 are fixed on the outer side of the heat exchange plate 201 and are disposed inside the outer cavity 202. A second fan 206 is installed on the side of the housing 1. The air outlet direction of the second fan 206 corresponds to that of the outer cavity 202. A placement chamber 102 is provided inside the housing 1. A first fan 205 is installed on the inner wall of the placement chamber 102. The air outlet direction of the first fan 205 corresponds to that of the inner cavity 203. The heat exchange plate 201 and the heat dissipation fins 204 work together to increase the heat dissipation area and improve the heat exchange efficiency. The first fan 205 and the second fan 206 control the airflow in the inner cavity 203 and the outer cavity 202 respectively, realizing independent regulation of internal and external circulation, avoiding direct entry of external humid air into the equipment chamber, and effectively preventing internal components from getting damp.

[0026] The second fan 206 is located on the opposite side of the housing 1 relative to the first fan 205, and the air outlet directions of the first fan 205 and the second fan 206 are opposite. A filter plate 207 is provided on the opposite side of the housing 1 relative to the second fan 206. A first ventilation opening 104 and a second ventilation opening 107 are respectively opened on both sides of the housing 1. The filter plate 207 and the second fan 206 are both embedded inside the second ventilation opening 107. The second fan 206, the outer cavity 202, and the filter plate 207 constitute a first air duct, which is connected to the outside. The first ventilation opening 104 is located on the opposite side of the second ventilation opening 107, and the second fan 206 is embedded inside the first ventilation opening 104. The first fan 205… The inner cavity 203 and the first vent 104 constitute the second air duct, which is connected to the placement chamber 102. The first air duct exchanges heat with the second air duct through the heat exchange plate 201 and the heat dissipation fins 204. The filter plate 207 blocks dust from entering, preventing dust from accumulating on the surface of the heat exchange plate 201 and affecting the heat dissipation effect. The first air duct and the second air duct are physically isolated by the heat exchange plate 201 to prevent moisture from seeping into the inner cavity 203. The second air duct ensures air circulation in the equipment chamber. At the same time, the first fan 205 and the second fan 206 force convection, so that the second air duct exchanges heat indirectly with the first air duct through the heat exchange plate 201, which not only ensures heat dissipation efficiency but also isolates external moisture and further avoids the risk of short circuit.

[0027] The heat exchange assembly 2 also includes a baffle 210. A movable chamber 103 is provided inside the housing 1. The baffle 210 passes through the movable chamber 103. A connecting rod 209 is rotatably connected to the lower surface of the baffle 210. An electric actuator 208 is fixed to the inner wall of the movable chamber 103. The output end of the electric actuator 208 is rotatably connected to the connecting rod 209. The baffle 210 moves within the movable chamber 103 via the electric actuator 208 and the connecting rod 209. There are two sets of each of the baffle 210, electric actuator 208, and connecting rod 209, and they are respectively located at the first ventilation opening 104. Inside the second ventilation opening 107, the first ventilation opening 104 and the second ventilation opening 107 are separated by a baffle 210. Under normal operating conditions, the baffle 210 is closed to maintain a sealed internal circulation state and ensure protection. When the temperature inside the chamber is too high and heat dissipation needs to be enhanced, the controller controls the electric push rod 208 to move and retract the baffle 210, so that the second fan 206 and the first fan 205 can directly introduce cold air from the outside into the placement chamber 102 for forced air cooling, thereby achieving rapid cooling and balancing safety under normal conditions with heat dissipation efficiency under extreme operating conditions.

[0028] Adjustment component 3 includes a knob 301 located on one side of housing 1. A bidirectional threaded rod 302 is fixed to the side of the knob 301. A transmission chamber 105 is provided inside housing 1. The other end of the bidirectional threaded rod 302 is rotatably connected to the inner wall of the transmission chamber 105. A threaded cap 303 is threadedly connected to the surface of the bidirectional threaded rod 302. A connecting block 304 is fixed to the upper surface of the threaded cap 303. A mounting plate 305 is fixed to the upper surface of the connecting block 304. By rotating the knob 301, the bidirectional threaded rod 302 is moved, thereby synchronously adjusting the position of the mounting plates 305 on both sides. It can adapt to various mounting brackets or bases of different sizes without tools, improving the installation convenience and versatility of the equipment. The threaded cap 303, connecting block 304, and mounting plate 305 all have Two sets of screw rods are symmetrically arranged at both ends of the bidirectional threaded rod 302. The upper surface of the housing 1 has a movable groove, and the transmission chamber 105 is connected to the movable groove. The connecting block 304 passes through the movable groove. The side of the housing 1 also has a drainage groove 106, which is connected to the transmission chamber 105. The surfaces of the bidirectional threaded rod 302, the connecting block 304, and the threaded cap 303 are all coated with a waterproof coating. The drainage groove 106 can drain the liquid entering the transmission chamber 105 in a timely manner, preventing it from accumulating and causing corrosion of the internal mechanism. At the same time, the waterproof coating on the surfaces of the bidirectional threaded rod 302, the threaded cap 303, and the connecting block 304 further enhances the overall corrosion resistance and moisture resistance, ensuring the long-term reliability and service life of the adjustment mechanism in humid environments.

[0029] It should be noted that the enclosure 1 houses the battery, controller, communication module, battery management system, and heating module. The front of the enclosure 1 has a door 101, which integrates the core functional units such as the battery, controller, and communication module inside the enclosure 1. The controller intelligently coordinates the operation of the fan, electric actuator 208, and heating module, which not only achieves intelligent heat dissipation and thermal management, but also constitutes a complete, efficient, reliable, and remotely monitored independent photovoltaic lighting control system, thereby improving the overall performance and intelligence level of the entire solar lighting system.

[0030] The working principle of the above embodiments is as follows: First, the operator turns the knob 301, which drives the bidirectional threaded rod 302 to rotate. The bidirectional threaded rod 302 drives the threaded cap 303 to move. The threaded cap 303 drives the connecting block 304 fixed on the upper surface and the mounting plate 305 fixed on the upper surface of the connecting block 304 to move, so that the mounting plate 305 can adapt to different installation environments. Then, the operator connects the device to an external power source and an internal controller.

[0031] When the internal temperature of the housing 1 is high, the controller controls the operation of the first fan 205 and the second fan 206. The second fan 206 draws in the outside cold air through the filter plate 207 into the outer cavity 202 and discharges it from the housing 1 through the first vent 104. At the same time, the first fan 205 introduces the high-temperature air inside the placement chamber 102 into the inner cavity 203 through the second vent 107. This allows the high-temperature air to indirectly exchange heat with the cold air inside the first air duct through the heat exchange plate 201 and the heat dissipation fins 204 in the second air duct, and then discharge it into the placement chamber 102 through the first vent 104, forming an internal circulation and thus completing the heat dissipation.

[0032] When the internal temperature of the housing 1 is too high, the controller controls the electric push rod 208 to operate, driving the connecting rod 209 and the baffle 210 hinged to the other end of the connecting rod 209 to move, thereby causing the baffle 210 to retract into the movable chamber 103. At this time, the second fan 206 is directly connected to the placement chamber 102 through the first vent 104, and the first fan 205 is connected to the outside through the second vent 107. At the same time, the first fan 205 is rotated in reverse, thereby allowing the outside cold air to directly enter the placement chamber 102 through the second vent 107, exchange heat with the high temperature air inside the placement chamber 102, and be discharged from the placement chamber 102 through the first vent 104 for rapid heat dissipation and cooling.
