Description

Technical Field

[0001] This invention belongs to the field of power equipment technology, specifically a gas circulation device for power plants. Background Technology

[0002] The plant is a building space specifically designed and constructed for the installation, operation, maintenance and management of various power generation equipment and related auxiliary facilities of the power station. It is the core infrastructure for the power station to realize energy conversion and power production, providing a suitable operating environment for the equipment and ensuring that the power station produces electricity safely, stably and efficiently.

[0003] In many power plant operations, ground-level powerhouses often face a thorny problem—excessively high internal temperatures. Ground-level powerhouses typically have large spatial spans and high roofs, but the design and layout of ventilation openings may be inadequate, hindering airflow. In the sweltering summer heat, the intense outside heat floods into the powerhouse like a tidal wave. When equipment operates under continuous high loads, it constantly radiates a large amount of heat. This heat rises, gradually drifting upwards, creating a distinct temperature stratification within the powerhouse—relatively low at the bottom and rapidly increasing at the top. The heat accumulates around the equipment, like a heavy blanket tightly enveloping it, causing the equipment temperature to rise continuously, leading to overheating and potential damage.

The moving mechanism includes a mounting shell fixedly connected to both sides of the outer surface of the main body. A square plate is provided inside the mounting shell. A caster wheel is fixedly installed at the bottom end of the square plate. The square plate and the mounting shell are elastically connected by an elastic element. A trapezoidal block is fixedly installed at the middle of the top of the square plate.

[0013] The extrusion assembly is located at the top inside the mounting housing and is capable of pushing the trapezoidal block down.

[0014] Preferably, the extrusion assembly includes a second motor fixedly connected to the top of the inside of the mounting housing. A bidirectional lead screw is fixedly installed at the output end of the second motor.

An extrusion wheel is rotatably connected to the bottom end of the U-shaped block.

[0015] Preferably, it further includes:

[0016] A limiting component one is disposed inside the mounting shell. The limiting component one includes a slide rail fixedly connected to the top of the inside of the mounting shell. A slider is slidably connected to the surface of the slide rail, and the bottom end of the slider is fixedly connected to two U-shaped blocks.

[0017] Preferably, it further includes:

[0018] Limiting component two is disposed at the top of the mounting plate. The limiting component two includes a vertical rod fixedly connected to the top of the mounting plate, and the surface of the vertical rod is designed to be smooth.

[0019] Preferably, a protective shell is fixedly installed on the top of the mounting plate on one surface of the motor, and heat dissipation holes are provided on both sides of the outer surface of the protective shell.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] This invention uses a drive motor to rotate a rotating disk and a protrusion. The protrusion drives a sliding ring to move back and forth. The sliding ring drives a sliding sleeve to slide on the surface of a fixed cylinder. During the sliding process, the ball bearings slide on the inner wall of the groove. During the sliding process, the fixed cylinder and the air outlet pipe can be rotated back and forth. The rotation of the air outlet pipe can increase the range of cold air ejection. Finally, the drive assembly makes the air outlet pipe rotate back and forth, thereby increasing the range of cold air ejection, accelerating the cooling of the upper part of the factory, and preventing the electronic equipment from overheating and being damaged.

[0024] This invention uses a drive motor to rotate a bidirectional lead screw, causing two U-shaped blocks to move on the surface of the lead screw. The U-shaped blocks drive the extrusion rollers to move to both sides of the trapezoidal block, and the extrusion rollers press the trapezoidal block down. The trapezoidal block pushes the square plate and the caster wheel down. As the square plate moves, the elastic element is compressed, and then the caster wheel contacts the ground and lifts the main body away from the ground. Finally, the extrusion assembly is driven to lift the main body away from the ground, thus allowing the operator to move the entire device without the need for auxiliary equipment, improving the convenience of the device.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] like Figures 1 to 5 As shown, the present invention provides a power plant gas circulation device, including a plant 1 and electronic equipment 2, and further comprising:

[0033] The rotating mechanism 3 is located inside the factory building 1. The rotating mechanism 3 includes a main body 301 located inside the factory building 1. An exhaust pipe 302 is fixedly installed inside the main body 301. An exhaust pipe 303 is rotatably connected to the top end of the exhaust pipe 302. A fixed cylinder 304 is fixedly fitted on the surface of the exhaust pipe 303. A sliding groove 305 is opened on the surface of the fixed cylinder 304. A sliding sleeve 306 is slidably fitted on the surface of the fixed cylinder 304. A ball bearing 307 located inside the sliding groove 305 is tumbledly connected inside the sliding sleeve 306.

[0034] Drive component 4 is disposed on the outer surface of exhaust duct 302;

[0035] The exhaust assembly 8 is located inside the exhaust duct 302.

[0036] The above solution is adopted: the operator installs the device on both sides of the electronic device 2. The heat generated by the electronic device 2 will flow upward. When the temperature inside the upper part of the factory 1 reaches a certain height, the temperature sensor at the top of the exhaust pipe 302 will send a signal, and then drive the exhaust assembly 8 to draw out the cold air from the bottom of the factory 1. The cold air will pass through the exhaust pipe 302, and then the exhaust pipe 303 will deliver the cold air to the upper part of the factory 1, thereby realizing heat exchange and ensuring that the air inside the upper machine room is in a low temperature state.

[0037] While the air outlet 303 discharges cold air, the drive assembly 4 can be driven to make the sliding sleeve 306 slide on the surface of the fixed cylinder 304. During the sliding process, the ball bearing 307 will slide on the inner wall of the groove 305. During the sliding process, the fixed cylinder 304 and the air outlet 303 can be driven to rotate back and forth. The rotation of the air outlet 303 can increase the spray range of cold air. Finally, by driving the drive assembly 4 to make the air outlet 303 rotate back and forth, the spray range of cold air is increased, the cooling of the upper part of the factory 1 is accelerated, and the electronic equipment 2 is prevented from overheating and being damaged.

[0038] like Figure 3 and Figure 4 As shown, the drive assembly 4 includes a mounting plate 401 fixedly connected to the outer surface of the exhaust pipe 302. A motor 402 is fixedly mounted on the top of the mounting plate 401. A rotating disk 403 is fixedly mounted on the output end of the motor 402. A sliding ring 405 is fixedly mounted on the side of the sliding sleeve 306 near the rotating disk 403. A protrusion 404 located inside the sliding ring 405 is fixedly mounted on one side of the rotating disk 403.

[0039] Using the above solution: Through the design of the drive component 4, the motor 402 can be driven to rotate the rotating disk 403. The rotating disk 403 will drive the protrusion 404 to slide inside the sliding ring 405. During the sliding process, the sliding ring 405 can be driven to move back and forth. The sliding ring 405 will drive the sliding sleeve 306 to slide back and forth on the surface of the fixed cylinder 304.

[0040] like Figure 3 As shown, the exhaust assembly 8 includes a drive component 801 fixedly connected inside the exhaust pipe 302, and a fan blade 802 is fixedly installed at the output end of the drive component 801.

[0041] The above solution is adopted: through the design of the exhaust component 8, the drive component 801 can be driven to make the fan blade 802 rotate. During the rotation of the fan blade 802, the cold air at the bottom of the factory 1 will be drawn in, thereby exchanging with the hot air at the top of the factory 1, so as to achieve cooling of the entire factory 1.

[0042] like Figure 5As shown, it also includes:

[0043] The moving mechanism 5 is disposed on both sides of the outer surface of the main body 301. The moving mechanism 5 includes a mounting shell 501 fixedly connected to both sides of the outer surface of the main body 301. A square plate 502 is disposed inside the mounting shell 501. A caster wheel 503 is fixedly installed at the bottom end of the square plate 502. The square plate 502 and the mounting shell 501 are elastically connected by an elastic member 504. A trapezoidal block 505 is fixedly installed at the middle of the top of the square plate 502.

[0044] The extrusion assembly 6 is located at the top inside the mounting housing 501 and is capable of pushing the trapezoidal block 505 down.

[0045] The above solution involves a moving mechanism 5 that drives the pressing component 6 to lower the trapezoidal block 505. The trapezoidal block 505 then lowers the square plate 502 and the caster wheel 503. As the square plate 502 moves, the elastic element 504 is compressed. Utilizing the elasticity of the elastic element 504, it pulls the square plate 502 and the caster wheel 503 back to their original positions. The caster wheel 503 then contacts the ground and lifts the main body 301 away from the ground. The operator can then push the device to rotate the caster wheel 503. This rotation facilitates the operator's movement of the entire device. Finally, by driving the pressing component 6, the caster wheel 503 lifts the main body 301 away from the ground, allowing the operator to move the entire device without the need for auxiliary equipment, thus improving the device's convenience.

[0046] like Figure 5 As shown, the extrusion assembly 6 includes a second motor 601 fixedly connected to the top of the inside of the mounting housing 501. A bidirectional lead screw 602 is fixedly installed at the output end of the second motor 601. U-shaped blocks 603 located on both sides of the trapezoidal block 505 are threadedly fitted on the surface of the bidirectional lead screw 602. An extrusion wheel 604 is rotatably connected to the bottom of the inside of the U-shaped block 603.

[0047] Using the above scheme: Through the design of the extrusion component 6, the motor 601 can be driven to rotate the bidirectional lead screw 602. Since the bidirectional lead screw 602 is threadedly connected to the U-shaped block 603, the two U-shaped blocks 603 will move relative to each other on the surface of the bidirectional lead screw 602. The U-shaped blocks 603 will drive the extrusion roller 604 to move to both sides of the trapezoidal block 505. Then the surface of the extrusion roller 604 will contact the surface of the trapezoidal block 505, and the extrusion roller 604 will squeeze the trapezoidal block 505 down.

[0048] like Figure 5 As shown, it also includes:

[0049] Limiting component 7 is disposed inside the mounting housing 501. Limiting component 7 includes a slide rail 701 fixedly connected to the top of the inside of the mounting housing 501. A slider 702 is slidably connected to the surface of the slide rail 701, and the bottom end of the slider 702 is fixedly connected to two U-shaped blocks 603.

[0050] The above solution is adopted: through the design of the limiting component 7, when the U-shaped block 603 moves, it will drive the slider 702 to slide on the surface of the slide rail 701. Since the slide rail 701 is square, it can limit the slider 702 and the U-shaped block 603, thereby ensuring the stability of the movement of the U-shaped block 603.

[0051] like Figure 3 and Figure 4 As shown, it also includes:

[0052] Limiting component 2 9 is disposed at the top of mounting plate 401. Limiting component 2 9 includes a vertical rod 901 fixedly connected to the top of mounting plate 401, and the surface of the vertical rod 901 is designed to be smooth. A limiting block 902 is slidably fitted on the surface of the vertical rod 901, and the limiting block 902 is fixedly connected to the surface of the sliding ring 405.

[0053] The above solution is adopted: through the design of the limiting component 2 9, when the sliding ring 405 moves back and forth, it will drive the limiting block 902 to slide on the surface of the vertical rod 901. The vertical rod 901 can limit the limiting block 902 and the sliding ring 405. Furthermore, the vertical rod 901 is designed to be smooth, which allows the limiting block 902 and the sliding ring 405 to move more smoothly.

[0054] like Figure 1 and Figure 2 As shown, a protective shell 10 is fixedly installed on the top of the mounting plate 401 on the surface of the motor 402, and heat dissipation holes are provided on both sides of the outer surface of the protective shell 10.

[0055] The above solution is adopted: through the design of the protective shell 10, since the protective shell 10 is set on the surface of the motor 402, it can protect the motor 402. Furthermore, heat dissipation holes are opened on both sides of the outer surface of the protective shell 10 to ensure heat dissipation of the motor 402 and improve the service life of the motor 402.

[0056] like Figure 4 and Figure 5 As shown, a contact plate 12 is fixedly installed at one end of the bidirectional lead screw 602. The surface of the bidirectional lead screw 602 is rotatably connected to a support block 11 located on one side of the two support blocks 11. The support block 11 is fixedly connected to the mounting shell 501. Dust screens are respectively provided on one side of the main body 301 and the exhaust pipe 302. The slide groove 305 is a curved design, and the surface of the ball bearing 307 is in contact with the inner wall of the slide groove 305.

[0057] The above solution is adopted: through the design of the support block 11 and the contact plate 12, when the bidirectional screw 602 rotates, it will drive the contact plate 12 to rotate. Since the opposite side of the two contact plates 12 is in contact with the surface of the support block 11, the bidirectional screw 602 can be limited, and the support block 11 can support the bidirectional screw 602. Through the design of the rotating mechanism 3, since the main body 301 and the exhaust pipe 302 are respectively provided with dust screens, dust is prevented from entering the interior of the main body 301 and the exhaust pipe 302. Furthermore, the slide groove 305 is a curved design, and the ball 307 will slide along the inner wall of the slide groove 305, thereby driving the fixed cylinder 304 to rotate back and forth.

[0058] Working principle and usage process of this invention:

[0059] First, the operator can drive motor 601 to rotate the bidirectional lead screw 602. The two U-shaped blocks 603 will move on the surface of the bidirectional lead screw 602. The U-shaped blocks 603 will drive the extrusion roller 604 to move to both sides of the trapezoidal block 505. The extrusion roller 604 will extrude the trapezoidal block 505 to descend. The trapezoidal block 505 will push the square plate 502 and the caster wheel 503 to descend. When the square plate 502 moves, the elastic element 504 will be compressed. Then the caster wheel 503 will contact the ground and lift the main body 301 away from the ground. Then the operator can push the device to rotate the caster wheel 503, which makes it convenient for the operator to move the entire device.

[0060] Then the device can be installed on both sides of the electronic device 2. When the temperature inside the upper part of the factory 1 reaches a certain level, the temperature sensor at the top of the exhaust pipe 302 will send a signal, and then drive the exhaust assembly 8 to draw out the cold air from the bottom of the factory 1. The cold air will pass through the exhaust pipe 302, and then the exhaust pipe 303 will deliver the cold air to the upper part of the factory 1, thereby achieving heat exchange to ensure that the air inside the upper machine room is at a low temperature. While the exhaust pipe 303 is discharging cold air, the motor 402 can be driven to rotate the rotating disk 403 and the protrusion 404. The protrusion 404 can drive the sliding ring 405 to move back and forth. The sliding ring 405 drives the sliding sleeve 306 to slide on the surface of the fixed cylinder 304. During the sliding process, the ball 307 will slide on the inner wall of the groove 305. During the sliding process, the fixed cylinder 304 and the exhaust pipe 303 can be driven to rotate back and forth. By utilizing the rotation of the exhaust pipe 303, the spray range of cold air can be increased, the cooling speed can be accelerated, and the operation process can be completed.
