Description

Technical Field

[0001] The present invention relates to the technical field of distribution cabinets, and more specifically, to an outdoor distribution cabinet with self-cleaning function. Background Art

[0002] Distribution cabinets are divided into power distribution cabinets, lighting distribution cabinets and metering cabinets, which are the end-level equipment of the power distribution system. A distribution cabinet is a general term for a motor control center. Distribution cabinets are used in occasions where the load is relatively dispersed and the number of circuits is small; the motor control center is used in occasions where the load is concentrated and the number of circuits is large, and distributes the electric energy of a certain circuit of the upper-level power distribution equipment to the nearby load. This level of equipment provides protection, monitoring and control for the load.

[0003] For outdoor distribution cabinets, there are many existing technologies, for example:

[0004] Chinese Patent Publication No. CN112821257B discloses an outdoor distribution cabinet, including a cabinet body. A ventilation and heat dissipation mechanism is fixedly connected to the top of the cabinet body. Ventilation strip holes are evenly arranged on the surface of the top of the guiding inclined plate. A blocking arc plate is fixedly connected to the position on the top of the guiding inclined plate and to the right of the ventilation strip holes. An inner conduction component is fixedly connected to the top of the protective top plate and near the left side below the guiding inclined plate. Filter screens are symmetrically and fixedly connected to the right side of the bottom of the protective top plate and the right side of the top of the protective top plate. One end of each filter screen away from the protective top plate and the guiding inclined plate is rotatably connected to a swing cleaning component. The present invention relates to the technical field of distribution cabinets. This outdoor distribution cabinet achieves automatic cleaning of the heat dissipation filter screen through wind power drive, improves the dust filtering effect during heat dissipation, and makes full use of the wind power in the environment.

[0005] During the use of outdoor distribution cabinets, since no one often conducts cleaning and management work on them, it is necessary to consider main issues such as heat dissipation, rain protection, and cleaning during design. When the temperature is relatively high on sunny days, heat dissipation treatment needs to be carried out on the cabinet body; when the temperature is relatively low on rainy days, waterproof treatment needs to be carried out on the cabinet body; since the distribution cabinet is installed outdoors, dust is likely to accumulate in the filter screen arranged in the heat dissipation slot, thus affecting the heat dissipation effect inside the cabinet. Moreover, most of the existing distribution cabinets achieve the respective functions of each structure by setting separate heat dissipation, waterproof, and cleaning structures, and it is difficult to organically combine the waterproof, heat dissipation, and cleaning processes. Due to the variety of internal parts and limited space in the distribution cabinet, the more structures are set, the more likely it is to affect the normal operation of the electrical components inside the distribution cabinet. For example, in the outdoor distribution cabinet proposed in the above cited patent, it only dissipates heat from the cabinet body through the ventilation and heat dissipation mechanism. During the heat dissipation process, although the wind power can drive the swing cleaning component to clean the heat dissipation filter screen, since the wind power as the driving force comes from natural wind, its power is limited, and the cleaning effect of the wind power on the dust on the surface of the heat dissipation filter screen is also limited.

[0006] In view of this, we propose a self-cleaning outdoor power distribution cabinet to improve the deficiencies in the existing technology. Summary of the Invention

[0007] The purpose of the present invention is to provide a self-cleaning outdoor power distribution cabinet to solve the problems raised in the above-mentioned background technology.

[0037] Embodiment

[0038] Please refer to Figures 1-9As shown in the figure, the purpose of this embodiment is to provide a self-cleaning outdoor power distribution cabinet, including an installation component 10. The installation component 10 includes a cabinet body 11. On a pair of side walls of the cabinet body 11 that are far away from each other, installation grooves 12 are provided. An air ventilation chamber 13 is provided inside the cabinet body 11 for the two installation grooves 12, and a negative pressure chamber 14 is provided outside the cabinet body 11 for the two installation grooves 12; a rain collection component 20 is provided on the top of the cabinet body 11. The rain collection component 20 is used to collect rainwater while shielding the cabinet body 11 from rain. The rain collection component 20 is communicated with the negative pressure chamber 14. A heat dissipation component 30 is provided in the installation groove 12. The heat dissipation component 30 is used to accelerate the rate of heat exchange of the air inside and outside the cabinet body 11. A trigger component 40 is provided at the interface between the rain collection component 20 and the negative pressure chamber 14 inside the negative pressure chamber 14. The heat dissipation component 30 can control the opening and closing of the trigger component 40 at the interface between the rain collection component 20 and the negative pressure chamber 14; a vibration component 50 is provided below the interface between the rain collection component 20 and the negative pressure chamber 14. The rain collection component 20 can drive the vibration component 50, which is used to vibrate the dust accumulated inside the heat dissipation component 30 to the outside. The heat dissipation component 30 can cooperate with the rainwater inside the negative pressure chamber 14 to cool the inside of the cabinet body 11 while the rain collection component 20 drives the vibration component 50. A cleaning component 60 is provided outside the air ventilation chamber 13 and the negative pressure chamber 14. The cleaning component 60 is used to clean the dust outside the heat dissipation component 30.

[0039] During rainy days, the cabinet body 11 is shielded from rain by the rain collection component 20, and at the same time, the rainwater falling into the rain collection component 20 is collected.

[0040] When the temperature rises on sunny days, the power supply of the heat dissipation component 30 is turned on to accelerate the rate of air flow inside and outside the cabinet body 11, thereby dissipating heat from the inside of the cabinet body 11. A negative pressure is formed inside the negative pressure chamber 14 due to the operation of the heat dissipation component 30, driving the trigger component 40 to slide towards the side close to the cabinet body 11. At this time, the interface between the rain collection component 20 and the negative pressure chamber 14 is opened, and the rainwater collected by the rain collection component 20 on rainy days falls into the negative pressure chamber 14, driving the vibration component 50 to operate;

[0041] The vibration component 50 continuously knocks on the side wall of the negative pressure chamber 14, vibrating the dust accumulated inside the negative pressure chamber 14 to the outside. During this period, the rainwater falling into the negative pressure chamber 14 forms water mist. On the one hand, the water mist cooperates with the heat dissipation component 30 to cool the inside of the cabinet body 11. On the other hand, the water mist passes through the cleaning component 60 and condenses into water droplets at the outlet end of the cleaning component 60, dripping onto the outer side wall of the negative pressure chamber 14, and then adsorbing the dust shaken out by the vibration component 50, thus achieving the self-cleaning effect on the negative pressure chamber 14.

[0042] First, the specific structure of the trigger component 40 is disclosed. The trigger component 40 includes a pair of limit bolts 41 fixedly connected to the inner top of the negative pressure chamber 14. A slide bar 42 is fixedly connected between the two limit bolts 41. An "L"-shaped retaining arm 43 is slidably connected to the slide bar 42. The top of the "L"-shaped retaining arm 43 is in contact with the interface between the pressure pipe 22 and the negative pressure chamber 14. A wind-catching plate 44 is provided at the bottom of the "L"-shaped retaining arm 43. A spring 45 is provided between the "L"-shaped retaining arm 43 and the limit bolt 41;

[0043] When the heat dissipation component 30 works, air is pumped from the negative pressure chamber 14 into the cabinet body 11, causing a negative pressure difference between the inside of the negative pressure chamber 14 and the outside. The outside air continuously replenishes the negative pressure chamber 14. During the flow of the air in the negative pressure chamber 14, the wind-catching plate 44 is pushed towards the side close to the cabinet body 11, thereby pushing the "L"-shaped retaining arm 43 away from the interface between the rain collection component 20 and the negative pressure chamber 14. The rainwater in the rain collection component 20 will fall into the negative pressure chamber 14. During this period, the spring 45 is always in a deformed state. After the heat dissipation is completed, the power supply of the heat dissipation component 30 is turned off. The air pressure inside the negative pressure chamber 14 is balanced with the outside. The wind-catching plate 44 loses the driving force of the air flow. Under the action of the restoring force of the spring 45, the "L"-shaped retaining arm 43 resets to seal the interface between the rain collection component 20 and the negative pressure chamber 14 again.

[0044] Secondly, the specific structure of the vibration component 50 is disclosed. The vibration component 50 includes a driving paddle 51 provided below the pressure pipe 22. A driving wheel 52 is coaxially connected to one side of the driving paddle 51. A driven wheel 53 is coaxially connected to one side of the driving wheel 52. A convex block 54 is eccentrically connected to the top of the driven wheel 53;

[0045] After the rainwater in the rain collection component 20 falls into the negative pressure chamber 14, the gravitational potential energy of the falling water flow is converted into the kinetic energy of the rotation of the driving paddle 51. The driving paddle 51 drives the driving wheel 52 to rotate. The driving wheel 52 then drives the driven wheel 53 to rotate. The driven wheel 53 drives the convex block 54 to continuously knock on the inner side wall of the negative pressure chamber 14, thereby vibrating the dust in the negative pressure chamber 14 to the outside.

[0046] Since it is necessary to collect rainwater while shielding the cabinet body 11 from rain, the rain collection component 20 includes a bottom groove 21 provided at the top of the cabinet body 11. Both sides of the bottom of the bottom groove 21 are communicated with a pressure pipe 22. The end of the pressure pipe 22 far from the bottom groove 21 is communicated with the negative pressure chamber 14.

[0047] The improvement lies in that: an elevating groove 23 is slidably connected to the outside of the pressure pipe 22, and several floating blocks 24 are arranged on the inner side wall of the elevating groove 23; the sum of the buoyancies of all the floating blocks 24 in water is greater than the sum of the gravities of all the floating blocks 24 and the elevating groove 23, and the joints between the bottom groove 21 and the elevating groove 23 are all sealed. After the rainwater fills the bottom groove 21, when the rainwater overflows from the bottom groove 21, it will generate buoyancy on the floating blocks 24, and the buoyancy of the rainwater on the floating blocks 24 drives the elevating groove 23 to rise, increasing the volume of the rainwater collection assembly 20 for the rainwater. After the weight of the rainwater increases, the rainwater enters the negative pressure chamber 14 through the pressure pipe 22, and the kinetic energy for driving the vibration assembly 50 will increase.

[0048] Since it is necessary to dissipate heat from the inside of the cabinet body 11, therefore, the heat dissipation assembly 30 includes a mounting frame arranged in the mounting groove 12 and a filter plate 32 clamped to the side of the negative pressure chamber 14 away from the mounting groove 12. A fan 31 is coaxially connected inside the mounting frame, and the fan 31 is driven by a motor.

[0049] The improvement lies in that: after the power is turned on, the fan 31 coaxially connected to the output shaft of the motor rotates, and the fan 31 extracts the air outside the cabinet body 11 into the cabinet body 11, accelerating the rate of heat exchange inside and outside, and at the same time, the dust in the air will be intercepted by the filter plate 32.

[0050] Since the dust in the filter plate 32 is automatically cleaned to prevent the dust from affecting the heat dissipation effect, therefore, the cleaning assembly 60 includes a return pipe 61 communicated with the upper part of the ventilation chamber 13. One end of the return pipe 61 away from the ventilation chamber 13 is communicated with a duckbill cover 62, and the duckbill cover 62 is located above the filter plate 32; the distance between the top of the filter plate 32 and the cabinet body 11 is less than the distance between the bottom of the filter plate 32 and the cabinet body 11.

[0051] The improvement lies in that: after the dust in the filter plate 32 is shaken to the outside by the convex block 54, it will accumulate on the outer surface of the filter plate 32. When the rainwater falls into the negative pressure chamber 14 and pushes the driving paddle 51 to rotate, a water mist will be formed in the negative pressure chamber 14. On the one hand, the water mist is extracted from the lower part of the ventilation chamber 13 into the cabinet body 11 by the fan 31 to enhance the cooling effect. On the other hand, the water mist will pass through the return pipe 61 from the upper part of the ventilation chamber 13 and condense into water droplets in the duckbill cover 62, and the water droplets will drip onto the inclined surface of the filter plate 32, washing away the dust staying here, thus completing the self-cleaning of the filter plate 32.

[0052] To sum up, the working principle of this solution is as follows: First, in rainy days, the cabinet body 11 is protected from rain by the bottom groove 21 and the elevating groove 23, and at the same time, the rainwater falling into the bottom groove 21 is collected.

[0053] When the temperature rises on sunny days, the power supply of the motor is turned on. The motor drives the fan 31 coaxially connected to its output shaft to rotate, accelerating the rate of air flow inside and outside the cabinet body 11, thereby dissipating heat from the inside of the cabinet body 11. At the same time, since the fan 31 sucks air from the negative pressure chamber 14 into the cabinet body 11, a negative pressure difference is formed between the inside of the negative pressure chamber 14 and the outside. The outside air continuously replenishes the negative pressure chamber 14. During the flow of the air in the negative pressure chamber 14, the wind-catching plate 44 is pushed towards the side close to the cabinet body 11, thereby pushing the "L"-shaped retaining arm 43 away from the interface between the pressure pipe 22 and the negative pressure chamber 14. The rainwater in the bottom groove 21 will flow down along the pressure pipe 22 into the negative pressure chamber 14. During this period, the spring 45 is always in a deformed state. After the heat dissipation is completed, the power supply of the fan 31 is turned off, and the air pressure inside the negative pressure chamber 14 is balanced with the outside. The wind-catching plate 44 loses the driving force of the air flow. Under the action of the restoring force of the spring 45, the "L"-shaped retaining arm 43 resets to seal the interface between the pressure pipe 22 and the negative pressure chamber 14 again;

[0054] After the rainwater in the bottom groove 21 flows into the negative pressure chamber 14, the gravitational potential energy of the water flow during the fall is converted into the kinetic energy for driving the driving paddle 51 to rotate. The driving paddle 51 drives the driving wheel 52 to rotate, the driving wheel 52 then drives the driven wheel 53 to rotate, and the driven wheel 53 drives the convex block 54 to continuously knock on the inner side wall of the filter plate 32, thereby vibrating the dust inside the filter plate 32 to the outside. The water mist generated by the water flow pushing the driving paddle 51 to rotate passes through the return pipe 61 and condenses into water droplets in the duckbill cover 62. The water droplets flow through the surface of the filter plate 32, adsorb the dust staying here, and take the dust away, thereby completing the self-cleaning of the filter plate 32.
