Technical Field

The invention relates to the technical field of fan equipment, in particular to a modular centrifugal fan.

Background technique

Modular centrifugal fans are equipment used for cooling and ventilation. One type is energy storage fans, which are wind energy conversion devices specially designed for energy storage systems. It uses wind energy to convert kinetic energy into electrical energy and stores it in energy storage devices such as batteries for later use. Energy storage fans are characterized by high efficiency, reliability and environmental protection. The working principle of this special fan is based on the conversion of wind energy. When the wind passes through the blades of the fan, the blades will rotate due to the impact of the airflow, and the rotating blades drive the generator to rotate, converting mechanical energy into electrical energy. In practical applications, this special fan is usually combined with energy equipment such as solar photovoltaics and batteries to form a hybrid energy storage system. Such a combination can make full use of natural resources. When the wind is strong or the sun is abundant, solar energy and wind energy are used to generate and store electricity at the same time to ensure stable power supply to the system. It is used in industrial refrigeration, but the airflow discharged by the centrifugal fan is fast and not uniform enough, which will cause obvious gas flow in the environment, affecting the user experience.

Detailed ways

The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

Please refer to Figures 1-11. The present invention provides a technical solution: a modular centrifugal fan, including a casing 1, with organic cooling ports 2 installed on both sides of the bottom of the casing 1, a pair of power generation components 8 installed inside the casing 1, each of the power generation components 8 is composed of two magnets installed on the casing 1 opposite to each other, and a blade 9 is rotatably connected between the two magnets inside the casing 1, at least two vents are installed outside the casing 1, each of the vents is installed with a plurality of support rods 25, and each of the support rods 25 is fixedly installed with a plurality of rectifier cavities 4 at equal distances, and a connecting rod 401 is fixedly installed at the upper and lower parts of one end of the rectifier cavity 4, and the two adjacent connecting rods 401 are in end-to-end contact, and the other end of the rectifier cavity 4 faces the inside of the casing 1, and the vents are respectively installed with a first windproof sheet 5 and a second windproof sheet 6 next to each support rod 25, and the first windproof sheet 25 is fixedly installed at the upper and lower parts of the rectifier cavity 4. The blade 5 and the second windproof blade 6 are mirror-symmetrical with the support rod 25 as the axis. An atomizer gun 3 is fixedly installed on the outside of the casing 1 near the bottom of the vent. The casing 1 is placed above the cooling unit and fixed with screws on all sides. When the blade 9 rotates, the main shaft of the blade 9 synchronously drives the wire to rotate between the power generation components 8 for storing electricity. At the same time, when the blade 9 rotates, it drives the wind inside the casing 1 to be diverted outward. In the process of the wind encountering the rectifier cavity 4, it enters the other end of the rectifier cavity 4 at one end, and then is led out to the outside of the casing 1 through the connecting rod 401 up and down, and the discharged wind inside the casing 1 is rectified up and down at the support rod 25. The winds of the two adjacent connecting rods 401 collide with each other head to tail and overflow to the surfaces of the first windproof blade 5 and the second windproof blade 6, and the wind is dispersed again on the first windproof blade 5 and the second windproof blade 6, thereby preventing the outside of the casing 1 from affecting the surrounding environment due to excessive wind force;

Furthermore, a transmission assembly for driving the first wind shield 5 and the second wind shield 6 to rotate is installed inside the casing 1, and a transmission belt 7 is connected to the rotating shaft of each blade 9. The inner ring of one end of the transmission belt 7 is connected to a roller 10, and the axis of the roller 10 is connected to a connecting rod 11. The casing 1 is internally rotatably connected to a gear group assembly connected to the transmission assembly. When the blade 9 rotates, the roller 10 is driven to rotate synchronously through the transmission belt 7. The rotation of the roller 10 drives the connecting rod 11 to rotate. When the connecting rod 11 rotates, it drives the gear group assembly for transmission.

Furthermore, the gear set assembly includes a first bevel gear 12 rotatably connected to one side of the vent inside the housing 1, a second bevel gear 13 coaxially connected to the first bevel gear 12, and a transmission roller 15 located at the bottom of the vent. A third bevel gear 14 is fixedly installed at one end of the transmission roller 15. The third bevel gear 14 and the second bevel gear 13 are meshed together. When the gear on the connecting rod 11 drives the first bevel gear 12 to rotate, the second bevel gear 13 is synchronously driven to rotate. When the second bevel gear 13 rotates, it drives the third bevel gear 14 to rotate. When the third bevel gear 14 rotates, it drives the transmission roller 15 to rotate synchronously. The transmission roller 1 5 rotates to generate centrifugal force to drive the transmission component to be thrown outward, hitting the bottom of the first windproof sheet 5 and the second windproof sheet 6. The initial positions of the first windproof sheet 5 and the second windproof sheet 6 are that one end of the first windproof sheet 5 is attached to one end of the second windproof sheet 6 to form a V-shape, and one end of the V-shape is in a closed state, which is used to prevent rainwater from directly entering and damaging the electronic equipment inside the casing. This requires changing the angle between the first windproof sheet 5 and the second windproof sheet 6. After the angle of the first windproof sheet 5 and the second windproof sheet 6 is changed, the V-shaped sealing end is opened, and the flowing air is rectified on the surface of one end of the first windproof sheet 5 and the second windproof sheet 6, so that the air circulation becomes smooth and the experience is improved.

Specifically, the transmission assembly includes a plurality of center plates 18 evenly distributed inside the transmission roller 15, the upper and lower sides of the center plate 18 are fixedly connected with first springs 17, one end of each of the first springs 17 is installed with a striking ball 16, and the position of each of the striking balls 16 corresponds to the bottom between the two support rods 25, the first windproof plates 5 and the second windproof plates 6 are respectively rotatably connected to the vents, and a switch assembly for starting the atomizer 3 for atomization is installed at the bottom between each group of the first windproof plates 5 and the second windproof plates 6. When the transmission roller 15 rotates, the centrifugal force generates to drive the striking ball 16 to move toward the edge of the transmission roller 15, and finally rotate toward the inside of the casing 1, and then the switch assembly is quickly struck during the rotation of the striking ball 16, so that the switch assembly cannot be reset in a short time, thereby turning on the power to heat the water inside the atomizer gun 3 to form water vapor and atomize the dust generated around.

Specifically, the switch assembly includes a roller 21 respectively installed at the bottom of the first windproof sheet 5 and the second windproof sheet 6, a push block 22 is fixedly installed at the bottom of the roller 21, a pressing plate 23 is installed at the bottom of the push block 22, a second spring 24 is connected to the bottom of each pressing plate 23, one end of the second spring 24 is fixed to the inside of the casing 1, and a delay switch 26 is installed next to each of the second springs 24 of the casing 1, and the hitting ball 16 is located between the two pushing blocks 22, wherein the hitting ball 16 rotates from the open end of a pair of pushing blocks 22 toward the closed end of a pair of pushing blocks 22, so that the pair of pushing blocks 22 move away from each other, and when the pair of pushing blocks 22 move away from each other, the second spring 24 is compressed, and at the same time, the pressing plate 23 is driven to contact the delay switch 26 during the rotation of the pair of pushing blocks 22, and the atomizing gun 3 is started to heat and atomize the surrounding air in the subsequent process.

A baffle 19 is installed between the opposite surfaces of the first windproof sheet 5 and the second windproof sheet 6. The two baffles 19 are staggered up and down and have an air outlet in the middle. An adjusting sheet 20 is fixedly installed at one end of each air outlet. The adjusting sheet 20 is close to one end of the rectifier cavity 4. When the first windproof sheet 5 and the second windproof sheet 6 rotate from the initial position, the two adjusting sheets 20 open to each other from the stacked state. The faster the blades 9 rotate, the greater the amount of air drawn out from the casing 1. The farther the two adjusting sheets 20 are from each other, the greater the rotation angle of the first windproof sheet 5 and the second windproof sheet 6, thereby preventing wind from being blocked inside the casing 1.

Furthermore, the first windproof sheet 5 includes a rectifying area 501 fixed to the roller 21, one end of the rectifying area 501 extends to the outside of the housing 1 and is bent to form a wind-removing area 502, a V-shape is formed between the first windproof sheet 5 and the second windproof sheet 6, and wind is removed on the surface of the wind-removing area 502. When the first windproof sheet 5 and the second windproof sheet 6 rotate, wind is introduced into the surface of the first windproof sheet 5 and the second windproof sheet 6, and the two rectifying areas 501 gradually become straight and close to parallel after the angle is opened. In this process, the inside of the housing 1 The wind from the first and second wind shields 5 and 6 respectively enters the inside and outside of the rectifying chamber 4. The wind inside the rectifying chamber 4 is rectified up and down by the connecting rod 401, and the wind outside the rectifying chamber 4 is diverted to the two sides outside the rectifying chamber 4 and the surfaces of the first wind shield 5 and the second wind shield 6 respectively. An obtuse angle is formed between the rectifying area 501 and the wind-dispersing area 502. After the two rectifying areas 501 are close to parallel, the wind-dispersing area 502 faces outward in a trumpet shape, and its surface flow velocity is lower than that of the rectifying area 501. The surface of the wind-dispersing area 502 is easy to collect dust, which is convenient for atomizing the air at this location.

The push block 22 is made of soft rubber. Since the ball 16 needs to hit the push block 22 repeatedly when rotating, it will continuously generate noise. Therefore, the push block 22 needs to be made of soft rubber to reduce noise. The adjusting piece 20 is made of metal, and the adjusting piece 20 can be iron. When the adjusting piece 20 contacts humid air, an oxide coating is formed to absorb water vapor, thereby effectively reducing the amount of water vapor entering the inside of the casing 1.

The atomizing gun 3 includes a water trough at the bottom of the vent, connecting rods at both ends of the water trough, and a filter plate installed inside the water trough, which is used to filter rainwater in the water trough when it rains. During the installation design, a heating wire is installed in the water trough to evaporate the accumulated water in the water trough, thereby forming water vapor from bottom to top, which is mixed with the air coming out of the vent, thereby atomizing the space coming out of the connecting rod 401, preventing the dust introduced into the casing 1 by the connecting rod 401 from scattering around the casing 1, thereby improving the cleanliness of the surrounding environment.
