Description

Technical Field

[0001] The present invention relates to the technical field of distribution cabinets, and particularly to an outdoor distribution cabinet with a dust-proof and ventilation structure. Background Art

[0002] As a key device for power distribution and control, outdoor distribution cabinets are widely used in various fields such as urban power grids, industrial plants, and residential communities. They undertake important functions such as receiving, distributing, and protecting electric energy, ensuring the stable transmission and supply of electricity; However, outdoor distribution cabinets face many challenges during operation. On the one hand, pollutants such as dust and particulate matter are abundant in outdoor air. These dusts easily enter the interior of the distribution cabinet along with the air. When the dust accumulates continuously on the surfaces of electrical components inside the distribution cabinet, it will affect the heat dissipation performance of the components, cause the component temperature to rise, and accelerate the aging of the components. On the other hand, outdoor distribution cabinets require good ventilation and heat dissipation conditions to maintain the normal working temperature of the internal electrical equipment. A large amount of heat is generated during the operation of the electrical equipment. If the heat cannot be dissipated in time, the working temperature of the equipment will continue to rise, thereby reducing the working efficiency of the equipment and shortening the service life of the equipment; The existing outdoor distribution cabinets are difficult to combine dust-proof effect and ventilation effect. Traditional distribution cabinets use ventilation holes for ventilation and heat dissipation, and do not have good dust-proof effect. The dust-proof measures of some distribution cabinets are relatively simple, only using ordinary filters for dust-proof, with poor dust-proof effect, easy to block the filters, and inconvenient to clean and maintain. At the same time, the ventilation structure has low ventilation efficiency, cannot effectively meet the heat dissipation requirements of the distribution cabinet, and it is difficult to ensure the normal operating temperature of the equipment in high-temperature environments. Summary of the Invention

[0003] To achieve the above objectives, the present invention is realized through the following technical solutions: An outdoor distribution cabinet with a dust-proof and ventilation structure, comprising: A cabinet body, on the front of which a cabinet door is rotatably installed. A handle is fixedly installed on the outer surface of the cabinet door. A rain shield is fixedly installed on the top of the cabinet body. The rain shield plays a role in shielding rainwater, preventing rainwater from directly hitting the cabinet body, and protecting the equipment inside the cabinet from rain erosion. Installation inclined pipes are fixedly installed on both sides of the cabinet body. The installation inclined pipes gradually incline downward away from the cabinet body. The inclined design of the installation inclined pipes is beneficial for drainage and guiding dust. A wedge-shaped groove is opened on the inner side surface of the installation inclined pipe. The wedge-shaped groove is arranged at the lower end of the installation inclined pipe. Support legs are fixedly installed at the four corners of the bottom of the cabinet body. An installation rack is fixedly installed inside the cabinet body. The installation rack is used for installing various electrical equipment inside the distribution cabinet; An air inlet mechanism, which is detachably installed inside the installation inclined pipe. The air inlet mechanism is used for introducing outside air into the interior of the cabinet body and has a dust-proof function at the same time; Ventilation mechanism, which is installed at the back of the cabinet body; Among them, the air inlet mechanism includes an air inlet pipe, and a spiral wind deflector is fixedly installed on the inner wall of the air inlet pipe. A fixing rod is fixedly installed in the middle of the spiral wind deflector. The fixing rod blocks the outside air from passing through the middle of the spiral wind deflector. The spiral wind deflector makes the air flow along the spiral direction, increasing the travel of the air and improving the dust separation effect. At the same time, the dust will be thrown towards the pipe wall under the action of centrifugal force. Spiral grooves and dust guide grooves are provided on the inner wall of the air inlet pipe.

[0004] Preferably, the dust guide groove is arranged inside the spiral groove. The dust guide groove is parallel to the axis of the air inlet pipe and is arranged at the lower part of the air inlet pipe. The spiral groove is arranged between the spiral wind deflectors. The spiral groove guides the air to move forward spirally and at the same time makes the dust move into the groove under the action of centrifugal force. The dust guide groove is used to collect the dust separated from the spiral groove and guide it to be discharged downward.

[0005] Preferably, wedge-shaped blocks are fixedly installed on both sides of the air inlet pipe. The wedge-shaped blocks are engaged and adapted with wedge-shaped grooves to realize the detachable connection between the air inlet pipe and the installation inclined pipe, which is convenient for installation and maintenance.

[0006] Preferably, a partition board is fixedly installed inside the cabinet body. The partition board is arranged below the installation frame. A blower is fixedly installed on the surface of the partition board. The partition board divides the internal space of the cabinet body into upper and lower chambers. The installation inclined pipe is arranged in the lower chamber. When the blower operates, a negative pressure is formed in the lower chamber, and the outside air is sucked in from the air inlet mechanism.

[0007] Preferably, the ventilation mechanism includes a dust-proof component, which is fixedly installed at the back of the cabinet body. The dust-proof component ensures ventilation while blocking the entry of dust. An auxiliary cleaning component is rotatably installed at the axis of the dust-proof component. The auxiliary cleaning component cleans the dust on the surface of the dust-proof component to prevent blockage.

[0008] Preferably, the dust-proof component includes a ventilation disc and a dust-proof disc. A ring plate is fixedly installed at the edge of the ventilation disc. A ring sleeve is fixedly installed at the edge of the dust-proof disc. The ring plate is slidably installed inside the ring sleeve. A first buffer spring is fixedly connected between the ring plate and the ring sleeve. The first buffer spring is arranged inside the ring sleeve. The first buffer spring plays a role in buffering vibration and adjusting the relative position between the ventilation disc and the dust-proof disc.

[0009] Preferably, a ventilation net is fixedly installed on the surface of the ventilation disc, and a dust-proof net is fixedly installed on the surface of the dust-proof disc. Both the ventilation net and the dust-proof net are fan-shaped structures, and the ventilation net and the dust-proof net are arranged alternately, making the air flow path longer and enhancing the dust-proof effect.

[0010] Preferably, a bearing is fixedly installed at the axis of the ventilation disc, and a first extrusion block is fixedly installed on the inner side surface of the collar. The number of the first extrusion blocks is twelve, and the twelve first extrusion blocks are evenly distributed on the inner side surface of the collar.

[0011] Preferably, the auxiliary cleaning member includes a rotating rod and a brush disc for cleaning the dust-proof net. The rotating rod is rotatably installed on the inner side surface of the bearing. The rotating rod penetrates through the dust-proof disc and extends to the outside thereof. A fan is fixedly installed at one end of the rotating rod away from the bearing. When the blower operates, the air in the cabinet is output from the ventilation mechanism, and the air flows through the fan to make it rotate. When the outdoor wind speed is relatively high, the rotating speed of the fan increases, and the ventilation efficiency of the power distribution cabinet is improved. Four limiting grooves are formed on the outer surface of the rotating rod, and the four limiting grooves are evenly distributed on the outer surface of the rotating rod.

[0012] Preferably, a slider is fixedly installed on the inner side surface of the brush disc. The slider is slidably installed inside the limiting groove. A second buffer spring is fixedly connected between the slider and the inner wall of the limiting groove. Twelve second extrusion blocks are fixedly installed on the outer side surface of the brush disc. The second extrusion blocks are in extrusion fit with the first extrusion blocks. When the fan rotates to drive the rotating rod to rotate, the slider is restricted by the limiting groove, so the brush disc also rotates accordingly. When the second extrusion blocks are in extrusion with the first extrusion blocks, the first extrusion blocks push the second extrusion blocks to move, and the slider slides in the limiting groove under the buffering action of the second buffer spring, and the brush disc moves to clean the dust-proof net on the dust-proof disc.

[0013] The present invention provides an outdoor power distribution cabinet with a dust-proof ventilation structure, which has the following beneficial effects: First, in the outdoor power distribution cabinet with the dust-proof ventilation structure, through the setting of the air inlet mechanism, when the blower operates, a negative pressure is formed in the lower chamber of the cabinet, and the outside air enters the air inlet pipe under the action of the negative pressure. The air flows along the spiral groove under the guidance of the spiral wind deflector. The dust slides down along the dust guide groove due to the action of gravity and centrifugal force and is discharged. After preliminary filtration, the air enters the cabinet. The spiral wind deflector, the spiral groove and the dust guide groove on the inner wall of the air inlet pipe cooperate with each other to realize the guidance of the incoming air and the separation of the dust, effectively blocking and separating the dust in the air and preventing the dust from entering the cabinet. The influence of dust on the electrical equipment in the power distribution cabinet is reduced, and the stable operation of the power distribution cabinet is ensured. At the same time, the wedge-shaped blocks on both sides of the air inlet pipe are clamped and adapted to the wedge-shaped grooves of the installation inclined pipe, which is convenient for the installation and disassembly of the air inlet mechanism and facilitates the later maintenance and cleaning.

[0014] Second, for the outdoor power distribution cabinet with this dust-proof ventilation structure, through the setting of the dust-proof component in the ventilation mechanism, air flows from the interior of the cabinet body through the space above the partition to the ventilation mechanism and is discharged through the ventilation disc and the dust-proof net. Under the action of the first buffer spring, the ring plate and the ring sleeve can adapt to a certain degree of vibration and displacement, ensuring the ventilation and dust-proof effects. The ventilation net and the dust-proof net are arranged alternately, extending the air flow path and enhancing the dust filtering effect. The structure composed of the ring plate, the ring sleeve and the first buffer spring can maintain the relative position stability of the ventilation disc and the dust-proof disc when the external environment vibrates, etc., ensuring the dust-proof performance. The ventilation mechanism blocks dust from entering while ensuring the ventilation and heat dissipation of the cabinet body, creating a clean operating environment for the equipment inside the cabinet and improving the reliability and stability of the equipment operation.

[0015] Third, for the outdoor power distribution cabinet with this dust-proof ventilation structure, through the setting of the auxiliary cleaning component in the ventilation mechanism, when the blower operates, the discharged air drives the fan to rotate, driving the rotating rod to rotate. Under the restriction of the limiting groove on the slider, the brush disc rotates accordingly. When the second extrusion block contacts and extrudes the first extrusion block, the first extrusion block pushes the second extrusion block, and the slider slides in the limiting groove under the buffering of the second buffer spring, causing the brush disc to move and clean the dust-proof net. The auxiliary cleaning component is driven by the air flow during the ventilation of the power distribution cabinet to achieve the automatic cleaning of the dust-proof net, timely removing the dust accumulated on the surface of the dust-proof net, avoiding the blockage of the dust-proof net and affecting the ventilation effect, eliminating the need for frequent manual cleaning, reducing the maintenance cost and labor input, and at the same time continuously ensuring the ventilation and dust-proof performance of the ventilation mechanism, guaranteeing the normal heat dissipation and stable operation of the power distribution cabinet.

[0016] Fourth, for the outdoor power distribution cabinet with this dust-proof ventilation structure, through the setting of the blower, when the blower operates, a negative pressure is formed in the lower chamber of the cabinet body. Under the action of the pressure difference, the outside air is sucked into the cabinet body through the air inlet mechanism, passes through the space above the partition, and finally is discharged from the ventilation mechanism on the back of the cabinet body, forming a continuous air circulation flow. The blower provides power for the flow of the air inside the power distribution cabinet. The blower drives the air circulation, which can significantly improve the ventilation efficiency and accelerate the heat dissipation speed compared with natural ventilation, ensuring that the heat generated by the electrical equipment inside the power distribution cabinet is discharged in time. At the same time, the stable negative pressure air inlet can make the air flow along the designed path, cooperating with the air inlet mechanism and the ventilation mechanism to achieve an efficient dust-proof ventilation effect. Effectively control the temperature inside the power distribution cabinet, avoid the decline in the performance or failure of electrical equipment caused by too high temperature, and extend the service life of the equipment.

A ring plate 813 is fixedly installed at the edge of the ventilation disc 811, and a ring sleeve 814 is fixedly installed at the edge of the dust-proof disc 812. The ring plate 813 is slidably installed inside the ring sleeve 814, and a first buffer spring 815 is fixedly connected between the ring plate 813 and the ring sleeve 814. The first buffer spring 815 is arranged inside the ring sleeve 814, and the first buffer spring 815 plays a role in buffering vibration and adjusting the relative position between the ventilation disc 811 and the dust-proof disc 812.

Both the ventilation net 818 and the dust-proof net 819 are fan-shaped structures, and the ventilation net 818 and the dust-proof net 819 are arranged alternately, making the air circulation path longer and enhancing the dust-proof effect. A bearing 816 is fixedly installed at the axis of the ventilation disc 811. The bearing 816 provides rotational support for the rotating rod 821 of the auxiliary cleaning member 82. An extrusion block 817 is fixedly installed on the inner side surface of the ring sleeve 814. The number of the extrusion blocks 817 is twelve, and the twelve extrusion blocks 817 are evenly distributed on the inner side surface of the ring sleeve 814. The auxiliary cleaning member 82 includes a rotating rod 821 and a brush disc 824. The brush disc 824 cleans the dust-proof net 819. The rotating rod 821 is rotatably installed on the inner side surface of the bearing 816. The rotating rod 821 passes through the dust-proof disc 812 and extends to its outside. A fan 822 is fixedly installed at the end of the rotating rod 821 away from the bearing 816. When the blower 11 operates, the air in the cabinet body 1 is output from the ventilation mechanism 8, and the air flows through the fan 822 to make it rotate. When the outdoor wind speed is relatively high, the rotating speed of the fan 822 increases, and the ventilation efficiency of the power distribution cabinet is improved.

[0022] During use, the blower 11 operates to form a negative pressure in the lower chamber of the cabinet body 1. The outside air is sucked in from the air inlet mechanism 6 under the action of the negative pressure. After the air enters the air inlet pipe 61, it flows along the spiral groove 65 under the action of the spiral wind deflector 63. The fixed rod 64 in the middle of the spiral wind deflector 63 blocks the outside wind from passing through the middle of the spiral wind deflector 63. The dust will slide down along the dust guide groove 66 under the action of gravity and centrifugal force, achieving preliminary dust prevention. After the air enters the cabinet body 1, it passes through the space above the partition 10 and is output from the ventilation mechanism 8 on the back of the cabinet body 1. The air flows through the fan 822 to make it rotate. The fan 822 rotates to drive the rotating rod 821 to rotate. The limit groove 823 on the outer surface of the rotating rod 821 restricts the slider 825, so that the brush disc 824 rotates accordingly. When the second extrusion block 827 is extruded by the first extrusion block 817, the first extrusion block 817 pushes the second extrusion block 827 to move. The slider 825 slides in the limit groove 823 under the buffering action of the second buffer spring 826. The brush disc 824 moves to clean the dust-proof net 819 on the dust-proof disc 812, preventing the dust-proof net 819 from being blocked. When the outdoor wind speed is relatively high, the rotation speed of the fan 822 increases, and the ventilation efficiency of the power distribution cabinet is improved.

[0023] The entire power distribution cabinet realizes the functions of dust prevention and ventilation through the air inlet of the air inlet mechanism 6, the ventilation of the ventilation mechanism 8, and the auxiliary cleaning member 82 cleaning the dust-proof member 81. At the same time, the rain shield 4 on the top of the cabinet body 1 can prevent rainwater from entering. The inclined design of the installation of the inclined pipe 5 and the cooperation of the wedge-shaped groove 12 and the wedge-shaped block 62 facilitate the installation and drainage of the air inlet mechanism 6.
