Description

Technical Field

[0001] The invention relates to the technical field of distribution boxes, in particular to a distribution box with a ventilation and dustproof structure. Background Art

[0002] The distribution box is a very important device in the power system. It mainly plays the following key roles: First, it undertakes the task of distributing electric energy, and reasonably distributes the input electric energy to different power circuits to meet the power demand of various electrical equipment. Secondly, the distribution box has a circuit protection function. By installing various protection devices, such as circuit breakers and fuses, when the circuit is overloaded, short-circuited, and other abnormal conditions occur, the circuit can be cut off in time to avoid electrical accidents and protect personal safety and electrical equipment from damage.

[0003] In addition, it can also realize certain control functions, such as start and stop control of certain equipment. Distribution boxes have various types and specifications according to different application scenarios and needs, and are widely used in construction, industry, civil and other fields. Its design and installation need to follow relevant electrical specifications and standards to ensure its safe, reliable and efficient operation.

[0004] Some distribution boxes need to be installed outdoors, and distribution boxes used outdoors need to ensure their ventilation and dust-proof effects to avoid accelerated aging of internal components. Ventilation means that larger ventilation holes need to be opened on the distribution box shell. Large ventilation holes cause excessive exposure of internal components of the distribution box, which cannot play a dust-proof role. As a result, the distribution box either has good dust-proof effect but poor ventilation effect, resulting in the inability to dissipate internal heat, which increases the accelerated aging of internal components; or has poor dust-proof effect but good ventilation effect, which causes dust to adhere to the internal components in large quantities. The dust coverage will reduce the service life of the internal components. Summary of the invention

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: A distribution box with a ventilation and dustproof structure, comprising a box body, a switch door is hingedly connected to the front end of the box body, a frame is fixedly connected to the top of the box body, and the frame is composed of support columns and square plates. There are four support columns, and the four support columns are located at the corners of the square plate;

[0006] A ventilation mechanism, wherein the ventilation mechanism is fixedly mounted on the bottom of the square plate;

[0007] A filter mechanism, wherein the filter mechanism is fixedly connected to the housing, and the lower end of the ventilation mechanism is located inside the filter mechanism;

[0008] Wherein, the box body includes an outer shell, a shell is arranged inside the outer shell, a partition is arranged at one end of the outer shell close to the shell, the number of the partitions is several, and the several partitions are vertically arranged on the left and right sides of the inner wall of the outer shell, an air outlet is opened at the bottom of the end of the outer shell away from the switch door, and the inner wall of the outer shell is symmetrically provided with heat dissipation holes, the two side walls of the box body have heat dissipation holes for natural ventilation, and the bottom and the rear end are both provided with air outlets and through holes for natural ventilation. By providing a plurality of heat dissipation holes, the air exchange between the inside of the distribution box and the outside world can be promoted, and the heat generated by the operation of the electrical components can be dissipated, so as to prevent the temperature in the box from being too high and affecting the performance of the components or even causing failures. At the same time, by providing a double shell structure of the outer shell and the outer cover, it is avoided that a large amount of dust is attached to the internal components during the ventilation and heat dissipation process, thereby reducing the service life of the internal components. The heat dissipation hole is located at the bottom of the partition, and the outer shell is provided with a through hole at the bottom close to the shell;

[0009] Preferably, the shell includes an outer cover, which provides a place for placing components. An extension plate is fixedly connected to one end of the outer cover close to the switch door, and the extension plate is fixedly connected to the inner wall of the outer shell. A heat sink is fixedly connected to the outer side of the outer cover. During operation, external wind enters between the outer shell and the outer cover through the ventilation mechanism and the filtering mechanism. A small part of impurities remaining in the wind follows the airflow and flows downward inside the outer cover and the outer shell. At this time, the airflow will pass through a plurality of mutually staggered partitions and heat sinks. By setting partitions and heat sinks, the direction of the airflow is guided so that the airflow contacts the heat sink and takes away the heat inside the outer cover. At the same time, dust will eventually separate from the airflow in the process of colliding with the partitions and heat sinks and naturally gather to the bottom of the outer shell under the action of gravity, and finally leave the distribution box through the through hole to avoid dust remaining inside the box, which makes subsequent cleaning work cumbersome. The heat sink and partitions are alternately tilted.

[0010] Preferably, the ventilation mechanism includes a round rod, which is fixedly connected to the square plate, and a cylinder is fixedly connected to the outer wall of the round rod. There are seven cylinders, and the seven cylinders are evenly distributed with the round rod as the center. A blade is fixedly connected to one end of the cylinder away from the round rod. By setting an odd number of blades, the dynamic load can be better balanced during rotation, and the vibration and noise caused by imbalance can be reduced, so that a relatively more stable and uniform airflow can be formed, and the heat dissipation or ventilation effects can be improved. The blade is spiral, and the blade is divided into two sections. The section of the blade close to the cylinder is bent and rotated counterclockwise, and the section of the blade away from the cylinder is bent and rotated clockwise. When working, by setting the blade to a curved shape, wind from multiple directions can enter the interior of the distribution box along the blade, and the wind blows the blade to rotate. The blade drives the round rod to rotate, and the round rod drives the extension rod to rotate, and then the extension rod drives the scraper to rotate, so as to clean the bottom of the fixed cylinder to prevent dust from clogging the filter hole on the fixed cylinder. The outer wall of the round rod is rotatably connected to a fixing ring, and the outer wall of the fixing ring is fixedly connected to a supporting plate, and one end of the supporting plate away from the fixing ring is fixedly connected to the bottom of the blade, and the fixing ring is fixedly connected to a fixing plate at one end away from the blade, and the fixing plate is slidably connected to a sliding rod at one end away from the fixing ring. The sliding rod is L-shaped, and a return spring is fixedly connected to the top of the fixing plate, a section of the sliding rod passes through the return spring, and the return spring is fixedly connected to the sliding rod, and the bottom of the round rod is fixedly connected to a cleaning mechanism, and the outer side of the round rod is fixedly connected to an extension rod, and one end of the extension rod away from the round rod is fixedly connected to the scraper.

[0011] Preferably, the cleaning mechanism includes a cylinder, the outer wall of the cylinder is slidably connected to a fixed rod, the fixed rod passes through the cylinder and extends to the interior of the cylinder, the end of the fixed rod away from the cylinder is fixedly connected to a cleaning plate, the outer wall of the cylinder is fixedly connected to a compression spring, the end of the compression spring away from the cylinder is fixedly connected to the cleaning plate, and the fixed rod passes through the compression spring.

[0012] Preferably, the filtering mechanism comprises a fixed cylinder, which is fixedly connected to the top of the shell, the upper end of the fixed cylinder penetrates the shell and is located below the square plate, the lower end of the fixed cylinder penetrates the shell and is located above the outer cover, filter holes are provided at the bottom and the outer side of the fixed cylinder, and a swivel is rotatably connected to the middle part of the fixed cylinder, and an annular groove is provided on the inner wall of the swivel. When working, the outside wind enters the distribution box through the blades, and the flow of wind drives the blades to rotate, and then the blades drive the round rod to rotate, and the round rod drives the sliding rod to rotate, so that the sliding rod slides inside the annular groove. When the internal heat is high, the staff rotates the swivel, and the swivel rotates, so that the internal sliding rod is stuck in the hook-shaped groove, and then the swivel drives the fixed ring to rotate on the round rod, so that the supporting plate drives the blades to rotate around the cylinder, thereby changing the inclination direction of the blades to control the wind. The cam is provided with a plurality of grooves, and the grooves are provided with a plurality of grooves. The grooves are provided with a plurality of grooves, and the grooves are provided with a plurality of grooves. The grooves are provided with a plurality of grooves, and the grooves are provided with a plurality of grooves. The grooves are provided with a plurality of grooves, and the grooves are provided with a plurality of grooves.

[0013] The present invention provides a distribution box with a ventilation and dustproof structure. It has the following beneficial effects:

[0014] 1. The distribution box with a ventilation and dustproof structure has heat dissipation holes for natural ventilation on both side walls of the box body, and air outlets and through holes for natural ventilation on the bottom and rear end. The multiple heat dissipation holes can promote air exchange between the inside of the distribution box and the outside, help dissipate the heat generated by the operation of electrical components, prevent the temperature in the box from being too high and affecting the performance of the components or even causing malfunctions. At the same time, by setting a double shell structure of the outer shell and the outer cover, it is avoided that a large amount of dust is attached to the internal components during the ventilation and heat dissipation process, thereby reducing the service life of the internal components.

[0015] 2. The distribution box with a ventilation and dustproof structure guides the flow of air by setting partitions and heat sinks, so that the airflow contacts the heat sink and takes away the heat inside the outer cover. At the same time, the dust will eventually break away from the airflow in the process of colliding with the partitions and heat sinks and naturally gather to the bottom of the outer shell under the action of gravity, and finally leave the distribution box through the through holes to prevent the dust from remaining inside the box.

[0016] 3. The distribution box with a ventilation and dustproof structure has blades that are curved so that wind from multiple directions can enter the interior of the distribution box along the blades. At the same time, the wind drives the blades to rotate, the blades drive the round rod to rotate, the round rod drives the extension rod to rotate, and then the extension rod drives the scraper to rotate, thereby cleaning the bottom of the fixed cylinder to prevent dust from clogging the filter holes on the fixed cylinder.

[0017] Fourth, the distribution box with ventilation and dustproof structure is controlled by the staff by rotating the swivel, which makes the internal sliding rod stuck in the hook-shaped groove, and then the swivel drives the fixed ring to rotate on the round rod, so that the support plate drives the blades to rotate around the cylinder, and then changes the inclination direction of the blades to control the flow direction of wind, thereby improving the ventilation efficiency.

A blade 43 is fixedly connected to one end of the cylinder 42 away from the round rod 41. By setting an odd number of blades 43, the dynamic load can be better balanced during rotation, and the vibration and noise caused by imbalance can be reduced, so that a relatively more stable and uniform airflow can be formed, and the heat dissipation or ventilation effects can be improved. The blade 43 is spiral, and the blade 43 is divided into two sections. The section of the blade 43 close to the cylinder 42 is bent and rotated counterclockwise, and the section of the blade 43 away from the cylinder 42 is bent and rotated clockwise. When working, by setting the blade 43 to a curved shape, wind from multiple directions can enter the inside of the distribution box along the blade 43. At the same time, the wind blows the blade 43 to rotate, and the blade 43 drives the round rod 41 to rotate. 41 drives the extension rod 410 to rotate, and then the extension rod 410 drives the scraper 411 to rotate, so as to clean the bottom of the fixed cylinder 51 to prevent dust from clogging the filter holes on the fixed cylinder 51.

[0037] The filter mechanism 5 includes a fixed cylinder 51, which is fixedly connected to the top of the housing 11. The upper end of the fixed cylinder 51 passes through the housing 11 and is located below the square plate. The lower end of the fixed cylinder 51 passes through the housing 11 and is located above the outer cover 121. Filter holes are provided at the bottom and outside of the fixed cylinder 51. By setting the fixed cylinder 51, impurities in the wind are filtered to prevent dust from entering the housing 11. The middle part of the fixed cylinder 51 is rotatably connected to a rotating ring 52. The inner wall of the rotating ring 52 is provided with an annular groove 53. When working, the outside The wind enters the distribution box through the blades 43, and the flow of wind drives the blades 43 to rotate, and then the blades 43 drive the round rod 41 to rotate, and the round rod 41 drives the slide bar 48 to rotate, so that the slide bar 48 slides inside the ring groove 53. When the internal heat is high, the staff rotates the rotating ring 52, and the rotating ring 52 rotates, so that the internal slide bar 48 is stuck in the hook-shaped groove, and then the rotating ring 52 drives the fixed ring 44 to rotate on the round rod 41, so that the support plate 45 drives the blade 43 to rotate around the cylinder 42, thereby changing the inclination of the blade The outer side of the rotating ring 52 is provided with corrugations, the inner wall of the annular groove 53 is provided with hook-shaped grooves, the end of the sliding rod 48 away from the fixing plate 46 is located inside the annular groove 53, and the middle part of the inner wall of the fixing cylinder 51 is fixedly connected with a fixing block 54, the fixing block 54 is hexagonal, and the fixing block 54 is located on the inner wall of the cylinder 491, and the fixing rod 492 is in contact with the fixing block 54.

[0041] The round rod 41 drives the extension rod 410 to rotate, and the extension rod 410 contacts the cleaning plate 494, so that the cleaning plate 494 drives the fixed rod 492 and the cylinder 491 to rotate. At this time, the fixed rod 492 rotates around the surface of the fixed block 54 under the elastic force of the compression spring 493, and then under the shape of the fixed block 54, the fixed rod 492 knocks on the surface of the fixed cylinder 51, thereby cleaning the side wall of the fixed cylinder 51.
