Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of power boxes, in particular to a moisture-proof and heat-dissipation type power box applied to power engineering. BACKGROUND

[0002] In the field of power engineering, outdoor power boxes, as key equipment for power distribution, control, protection and management, often operate in harsh environments and face challenges such as moisture-proofing, heat dissipation, protection, energy supply and installation adaptation. Traditional power boxes have obvious shortcomings in moisture-proofing, mostly using a single dehumidification method, which is difficult to achieve precise dehumidification of different moisture-prone components inside the box. Components such as main switch devices and branch switches have many connection points, which are prone to short circuits and other faults due to moisture in a humid environment. Traditional devices cannot provide key protection for these critical parts, resulting in a high incidence of electrical faults in a humid environment, which seriously affects the stable operation of the power system. Insufficient heat dissipation is another major problem of traditional power boxes. Direct sunlight can cause the temperature inside the box to rise sharply. The sunshade and rainproof structure of traditional devices is not reasonably designed, making it difficult to effectively block heat conduction, resulting in high ambient temperature inside the box. At the same time, the heat dissipation device lacks specificity and cannot concentrate on heat dissipation for main heat-generating components such as circuit breakers and central processors, resulting in low heat dissipation efficiency and affecting the service life and operational stability of the device in high-temperature environments. In terms of protection, the safety protection measures of traditional power boxes are relatively single, relying only on key locks of safety doors, which cannot effectively prevent the opening of power boxes by human curiosity or maliciousness, thereby causing equipment damage, electric shock and other safety hazards, posing a great risk to the outdoor safe operation of power boxes. In terms of energy supply, traditional power boxes mostly rely on traditional power, which not only increases energy consumption and operating costs, but also makes it difficult to ensure the normal operation of the device in some remote areas or power failure situations, lacking sustainability and flexibility. In terms of installation adaptability, traditional power boxes lack special auxiliary connecting components when facing outdoor installation scenes such as cylindrical power poles, making it difficult to fix and time-consuming and laborious during installation, which cannot meet the rapid installation needs of different outdoor environments. Therefore, the present application provides a moisture-proof and heat-dissipation type power box applied to power engineering. SUMMARY

[0014] The above-mentioned at least one technical solution adopted by the embodiment of the present application can achieve the following beneficial effects: Firstly, through the coordinated operation of the dehumidifying device and the auxiliary wind direction changing device, the integrated dehumidifying and directional air supply functions are realized: the dehumidifying device efficiently reduces the overall humidity in the box, and the auxiliary wind direction changing device can accurately guide the dry air flow to the key parts such as the terminal, forming a double moisture-proof mechanism of "global dehumidification + key protection", greatly improving the moisture-proof efficiency in the box, reducing the electrical failure rate in humid environment, at the same time, the inverted V-shaped sunshade rainproof device at the top is designed with a 120°-150° golden angle, which can quickly guide and drain rainwater through the inclined slope, avoiding seepage into the box, and through the combination of the inner heat insulation layer and the outer reflective coating, it can effectively block the heat conduction caused by direct sunlight, reducing the temperature in the box by 8-12℃ compared with traditional equipment, significantly enhancing the long-term stable operation ability of the equipment in open high-temperature and rainy environment, adapting to different environments.

[0015] Secondly, since the power box is installed outdoors, someone may open it out of curiosity or other reasons, so in order to avoid damage and electric shock caused by opening the power box, the device adopts double protection, the safety door itself needs to be opened with a key, and on this basis, the device designs a hidden anti-opening device, which hides the anti-opening knob to prevent others from opening the power box, and when it is necessary to open the power box, rotate the anti-opening knob to make the upper end of the anti-opening knob come out of the anti-opening hole, then open it with a key, and when the safety door is closed, rotate the anti-opening knob to make the upper end of the anti-opening knob extend into the anti-opening hole to form a limit.

[0016] Thirdly, the main components that need to be dehumidified in the power box are the main switch device and the branch switch, because there are many lines and connection points, short circuits and other situations are easy to occur in humid conditions, therefore, for this situation, the device can concentrate on dehumidifying the main switch device and the branch switch to achieve the best dehumidifying effect, when the humidity sensor on the main switch device alarms, dehumidifying operation is needed, two first micro-motors are driven to rotate the corresponding connecting shafts, finally driving the corresponding wind direction changing baffles to rotate, the two wind direction changing baffles play the role of wind direction guiding, at this time, the dehumidifying device is started to dehumidify the main switch device, in this case, the required components can be dehumidified accurately in priority, greatly improving the moisture-proof efficiency in the box, reducing the electrical failure rate in humid environment, and when the humidity sensor on the branch switch alarms, the principle is the same, two first micro-motors drive the corresponding wind direction changing baffles to the direction of the branch switch, and the wind direction of the dehumidifying device is guided to the direction of the branch switch, at the same time, the circuit breaker and the central processor also need dehumidifying operation.

[0017] Fourthly, the main components needing heat dissipation in the power box are the circuit breaker and the central processor, therefore, aiming at this case, the device can focus on the heat dissipation of the circuit breaker and the central processor located inside the power box, when the temperature sensor alarms that the temperature of the central processor is too high, the corresponding adjusting shaft is driven to rotate by the second micro motor, and finally the adjusting plate is driven to rotate, the adjusting plate plays the role of wind direction guiding, at this time, the central processor is cooled by the radiator, in this case, the required components can be cooled accurately, the heat dissipation effect in the box is greatly improved, and the same is true for the circuit breaker, the main switch device and the branch switch, the angle of the adjusting plate is changed by the driving of the second micro motor, so as to achieve the effect of full-area or concentrated heat dissipation in the box, and finally the hot air in the power box is discharged by the cooling fan through the tapered heat dissipation port.

[0018] Fifthly, the heat dissipation effect is excellent, the top inverted V-shaped sunshade rainproof device adopts a 120°-150° golden angle design, the combination structure of the inner heat insulation layer and the outer light reflecting coating can effectively block the heat conduction caused by direct sunlight, so that the environment temperature in the box is reduced by 8-12℃ compared with the traditional device. At the same time, the auxiliary adjusting device, the radiator and the cooling fan work cooperatively to concentrate on the heat dissipation of the main heating components such as the circuit breaker and the central processor. The angle of the adjusting plate is changed by the driving of the second micro motor, so as to realize the full-area or concentrated heat dissipation in the box, and finally the hot air is discharged by the cooling fan through the tapered heat dissipation port, which not only ensures the heat dissipation efficiency, but also avoids the dust entering, and significantly enhances the long-term stable operation ability of the device in the open high-temperature environment.

The radiator 3 and the dehumidification device 2 are prior arts, the core principle of the radiator 3 is to enhance heat conduction by optimizing heat transfer path and enhance convection and radiation by expanding heat dissipation area, efficiently transfer the heat of the heating equipment to the environment, and ensure that the equipment temperature is controlled in the safety range. In actual design, single or combined heat dissipation modes are selected according to the equipment heat, space limitation and environmental conditions to balance the heat dissipation efficiency and cost. The dehumidification device 2 is a dehumidifier, and the core principle of the dehumidifier is to separate water vapor in the air by condensation cooling or adsorption / absorption to reduce the environmental humidity. According to different working modes, it is mainly divided into two categories of compressor type dehumidifier condensing type and rotary type dehumidifier adsorption type, and the core principles are different, but the ultimate goal is to realize "air dehumidification".

[0024] The device realizes integrated dehumidification and directional air supply functions through the cooperative operation of the dehumidification device 2 and the auxiliary wind direction changing device 4: the dehumidification device 2 efficiently reduces the overall humidity in the box, and the auxiliary wind direction changing device 4 can accurately guide the dry air flow to the key parts such as the terminal, forming a double moisture-proof mechanism of "global dehumidification + key protection", greatly improving the moisture-proof efficiency in the box, reducing the electrical failure rate in the humid environment, and at the same time, the inverted V-shaped sun-shading rain-proof device 6 on the top is designed through a 120°-150° golden angle, which can quickly guide and drain rainwater through the inclined slope, avoid seepage into the box body, and through the combined structure of the inner heat insulation layer and the outer reflective coating, effectively block the heat conduction caused by direct sunlight, reduce the temperature in the box by 8-12℃ compared with the traditional equipment, and significantly enhance the long-term stable operation ability of the equipment in the open high-temperature and rainy environment, adapt to different environments.

[0025] Preferably, the power box 1 is internally provided with a central processor 11, a main switch device 12, a circuit breaker 13 and a branch switch 14, the power box 1 is provided with a safety door 17, the safety door 17 is provided with an alarm prompt lamp 15, the lower end of the hidden cover 113 is provided with a hidden anti-opening device 112, the inside of the power box 1 is provided with a partition 16, and the central processor 11, the main switch device 12, the circuit breaker 13 and the branch switch 14 inside the power box 1 are all provided with humidity sensors and temperature sensors.

[0026] All humidity sensors and temperature sensors inside the power box 1 are electrically connected with the sunshade and rainproof device 6, the dehumidifying device 2, the radiator 3, the radiator fan 31, the auxiliary wind direction changing device 4 and the auxiliary adjusting device 5; The humidity sensors and temperature sensors inside the power box 1 and the electrically connected system formed by the sunshade and rainproof device 6, the dehumidifying device 2, the radiator 3, the radiator fan 31, the auxiliary wind direction changing device 4 and the auxiliary adjusting device 5 are an intelligent linkage system based on real-time monitoring and dynamic regulation and control, the principle of which can be divided into humidity control closed loop and temperature control closed loop, and the two closed loops cooperate with each other to jointly ensure the stability of the environment inside the power box 1. In the humidity control closed loop, the humidity sensors distributed on the main switch device 12, the branch switch 14, the circuit breaker and the central processor 11 continuously capture the humidity data around the key components. When the humidity value of any component exceeds the preset safety threshold, the corresponding sensor immediately generates an electrical signal, which is transmitted synchronously to the dehumidifying device 2 and the auxiliary wind direction changing device 4 through the electrical link: after receiving the signal, the dehumidifying device 2 starts quickly and sends dry air flow into the box through the side dehumidifying port; at the same time, the two first micro motors 41 of the auxiliary wind direction changing device 4 operate according to the signal instruction, driving the connecting shaft 42 and the wind direction changing baffle 43 sleeved thereon to rotate — if the humidity of the main switch device 12 exceeds the standard, the baffle is rotated to the angle of aiming at the main switch device 12, accurately guiding the dry air flow to the area; if the branch switch 14, the circuit breaker or the central processor 11 needs to be dehumidified, the baffle adjusts the direction accordingly to realize "targeted dehumidification". When the humidity sensor detects that the humidity of the target component decreases to the safe range, it immediately sends a stop signal, the dehumidifying device 2 stops running, and the wind direction changing baffle 43 resets, forming a complete humidity control closed loop, which maximizes the reduction of short circuit risk caused by humidity through the "global dehumidification + key directional" mode. The temperature regulation closed loop relies on temperature sensors installed on the heat generating components such as circuit breakers and central processors 11 to operate accurately. When the component temperature exceeds the set upper limit, the temperature sensor sends an electrical signal, triggering multiple cooling mechanisms through electrical connection: the radiator 3 starts to send air from the top down, the second micro motor 51 of the auxiliary adjustment device 5 drives the adjustment shaft 52 to rotate, and the adjustment plate 53 is adjusted to the appropriate angle to guide the cooling airflow to the high-temperature components; at the same time, the radiator fan 31 at the lower end of the power box 1 starts to work, and the heat accumulated in the box is quickly discharged through the conical heat dissipation port 111, forming a "top air supply + bottom exhaust" convection heat dissipation channel. If the temperature in the box continues to be high due to external sunlight, the temperature signal will also be transmitted to the sunshade and rainproof device 6, prompting the electric cylinder 62 to drive the telescopic shaft 63 to rise, and the X-shaped telescopic rod 65 to expand, so that the inner heat insulation layer + outer reflective coating of the inverted V-shaped sunshade cloth 66 fully expands at a golden angle of 120°-150°, reducing the external heat transfer by increasing the sunshade area and heat insulation effect. When the temperature sensor detects that the component temperature returns to the normal range, it sends a shutdown signal, and the radiator 3 and the radiator fan 31 stop working, and the adjustment plate 53 resets. The sunshade and rainproof device 6 can also be retracted according to the needs, completing the temperature regulation closed loop. In addition, the signal transmission of the two closed loops is implicitly coordinated by the central processor 11 inside the power box 1, ensuring the coordination of the actions of each device — for example, when humidity and temperature regulation are started at the same time, the central processor 11 optimizes the angle of the baffle 43 and the adjustment plate 53 through sensor feedback signals to avoid airflow interference and improve regulation efficiency. The entire system does not require manual intervention, and through the "monitoring - triggering" of the sensor, the "response - execution" of the device, and the "feedback - shutdown" of the sensor, it forms a fully automatic environmental regulation cycle, always maintaining the humidity and temperature in the box within the range suitable for equipment operation, significantly improving the reliability of the power box 1 in complex outdoor environments.
