Description

Technical Field

[0001] This invention relates to the field of ventilation technology, specifically to an energy-saving building ventilation device for civil defense projects. Background Technology

[0002] When civil defense projects are completed, ventilation equipment will be installed to reduce underground humidity and ensure ventilation, so that the underground civil defense system can maintain good air quality.

[0003] Patent publication number CN222634722U relates to a high-efficiency and energy-saving ventilation device for civil defense projects, comprising a first shell, a second shell, and a transmission device. There are two second shells, located on opposite sides of the first shell. A motor is installed on the inner wall of the first shell, and a first fan blade is installed at the motor's output end. Second fan blades are also installed on the inner wall of the second shell. The transmission device is located on the surface of the first shell and includes an air collection hood installed on one side of the first shell. This patent, by setting up a transmission device, allows multiple ventilation devices to rotate and ventilate using air discharged from one set of ventilation equipment, thereby saving energy. This effectively reduces the energy consumption problem in existing civil defense projects where multiple axial flow fans are often installed for ventilation, each powered independently, resulting in significant energy waste when operating simultaneously. This improves the overall energy-saving effect of the equipment.

[0004] In the aforementioned patent, the air discharged by a set of ventilation equipment drives multiple sets of ventilation equipment to rotate and ventilate, thereby saving energy. This can effectively reduce the situation in existing civil defense projects where multiple axial flow fans are installed for ventilation, each axial flow fan is powered separately and rotates independently, resulting in a large amount of energy consumption when working simultaneously. This improves the overall energy-saving effect of the equipment. However, after long-term use, a layer of dust will accumulate on the ventilation equipment, which will reduce air circulation and affect the normal ventilation of the equipment. Summary of the Invention

[0006] To achieve the above objectives, the present invention provides the following technical solution: an energy-saving building ventilation device for civil defense engineering, comprising: a fixed plate; an electrically retractable plate, the electrically retractable plate being fixedly installed at the bottom of the fixed plate; a fixed frame, the fixed frame being fixedly installed at the output end of the electrically retractable plate; a ventilation duct, the ventilation duct being fixedly installed on the surface of the fixed frame; a ventilation device, the ventilation device being disposed on the inner wall of the ventilation duct; an L-shaped frame being fixedly installed at the bottom of the fixed plate; a sliding frame being slidably installed at the bottom of the L-shaped frame; an arc-shaped scraper being fixedly installed on the surface of the sliding frame; a connecting plate being fixedly installed at the bottom of the fixed frame; a short plate being fixedly installed on the surface of the connecting plate; a short rod being fixedly installed on the side of the short plate near the sliding frame; a guide groove being formed on the surface of the sliding frame; a rotating shaft being rotatably installed on the inner wall of the guide groove; a rotating plate being fixedly installed on the surface of the rotating shaft; the sliding frame moving away from the ventilation duct will cause the arc-shaped scraper to move away from the ventilation duct, thereby disengaging from the filter screen.

[0007] According to the above technical solution, a first spring is provided between the L-shaped frame and the sliding frame. The surface of the sliding frame is driven by the elastic force of the first spring itself. A first torsion spring is provided between the guide groove and the rotating shaft. The rotating shaft is reset by the elastic force of the first torsion spring itself. The rotating plate is in contact with the inner wall of the guide groove.

[0008] According to the above technical solution, the sliding frame is equipped with a dust collection device and a dust discharge device. The dust collection device includes a long plate, a toothed plate, a rotating plate, a limiting plate, and an L-shaped plate. The rotating plate moves away from the ventilation duct as the sliding frame moves away from the ventilation duct, and the rotating plate contacts the toothed plate as it moves away from the ventilation duct. The L-shaped plate is fixedly installed on the surface of the sliding frame, the long plate is fixedly installed on the surface of the L-shaped plate, the toothed plate is fixedly installed on the surface of the long plate, the rotating plate is rotatably mounted on the top of the arc-shaped scraper, and the limiting plate is fixedly installed on the top of the arc-shaped scraper. According to the above technical solution, a push plate is fixedly installed on the side of the L-shaped plate near the arc-shaped scraper. The push plate is slidably connected to the inner wall of the sliding frame. A collection frame is fixedly installed at the bottom of the sliding frame. When the sliding frame moves away from the ventilation duct, the push plate will push the impurities that fall into the sliding frame into the collection frame for recycling.

[0009] According to the above technical solution, a second torsion spring is provided between the rotating plate and the arc-shaped scraper. The rotating plate is reset by the elastic force of the second torsion spring itself. A second spring is provided between the push plate and the sliding frame. The push plate is reset by the elastic force of the second spring itself.

[0010] According to the above technical solution, the discharge device includes a fixed block, a rotating plate, and a square plate. The rotating plate moves away from the ventilation duct as the collection frame moves away from the ventilation duct. The movement of the rotating plate away from the ventilation duct causes the square plate to contact the fixed block. The fixed block is fixedly installed on the surface of the push plate. The rotating plate is rotatably installed on the inner wall of the collection frame. The square plate is fixedly installed on the top of the rotating plate.

[0011] According to the above technical solution, a pusher plate is fixedly installed at the bottom of the rotating plate, a sliding plate is slidably installed on the inner wall of the collection frame, a sealing slide plate is fixedly installed on the surface of the sliding plate, a water inlet pipe is connected to the surface of the collection frame, a water tank is provided at the top of the water inlet pipe, and a water outlet is fixedly installed at the end of the collection frame away from the water inlet pipe. When the sliding plate moves away from the pusher plate, it will drive the sealing slide plate to move away from the pusher plate. When the sealing slide plate moves away from the pusher plate, it will coincide with the water inlet pipe, so that the water inside the water inlet pipe enters the collection frame and the dust is reduced by the water.

[0012] According to the above technical solution, a No. 3 torsion spring is provided between the rotating plate and the collecting frame, and the rotating plate is reset by the elastic force of the No. 3 torsion spring itself. A No. 3 spring is provided between the collecting frame and the sliding plate, and the sliding plate is reset by the elastic force of the No. 3 spring itself.

[0013] This invention provides an energy-saving building ventilation device for civil defense projects. It has the following beneficial effects: (1) In this invention, the height of the ventilation device can be adjusted by moving the ventilation device downward, thereby improving the ventilation effect at the bottom of the building. At the same time, when the ventilation duct moves downward, the filter screen on the surface will come into contact with the arc-shaped scraper. The arc-shaped scraper will scrape off the dust and impurities adhering to the top of the filter screen, preventing the dust from clogging the filter screen and affecting the ventilation effect. By moving the arc-shaped scraper away from the ventilation duct, it will break away from the contact with the filter screen, preventing the continuous scraping of the filter screen during the reset process, which would cause the dust to be directly pushed to the ground by the arc-shaped scraper, affecting the cleanliness of the ground.

[0014] (2) In this invention, the rotating plate will contact the toothed plate when it moves away from the ventilation duct. When the toothed plate contacts the rotating plate, the rotating plate will be stopped by the limiting plate, causing the toothed plate to vibrate. The vibration shakes off the impurities adhering to the inner wall of the arc-shaped scraper, preventing the impurities from adhering to the arc-shaped scraper and affecting the subsequent scraping effect. At the same time, when the toothed plate is reset, the toothed plate will push the rotating plate to rotate away from the limiting plate. Without the limiting plate, the rotating plate will not vibrate with the toothed plate, preventing long-term vibration from causing severe wear on the surface of the toothed plate and affecting the service life of the equipment. At the same time, the pusher will push the impurities that fall into the sliding frame into the collection frame to recover the impurities and prevent the impurities from floating in the air, causing the air quality to deteriorate and affecting the user's breathing.

[0015] (3) In this invention, the square plate rotates downward, which drives the rotating plate to rotate downward. The rotating plate rotates downward, which opens the top of the collection frame, allowing dust to fall into the collection frame. When the rotating plate returns to its original position, it seals the collection frame to prevent dust from floating out of the collection frame and causing dust to re-attach to the filter screen, affecting the ventilation effect. At the same time, the sealing slide moves away from the push plate and coincides with the water inlet pipe, allowing water from the water inlet pipe to enter the collection frame. The water is used to suppress the dust and prevent the dust from being stirred up, thus affecting the dust suppression effect. At the same time, the dust will be discharged from the water outlet along with the water, preventing the dust from accumulating in the collection frame and affecting the dust removal effect.

Detailed Implementation

[0018] 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.

[0019] Please see Figure 1 - Figure 7One embodiment of the present invention is: an energy-saving building ventilation device for civil defense engineering, comprising: a fixed plate 1, an electric telescopic plate 2, the electric telescopic plate 2 being fixedly installed at the bottom of the fixed plate 1; a fixed frame 3, the fixed frame 3 being fixedly installed at the output end of the electric telescopic plate 2; a ventilation duct 4, the ventilation duct 4 being fixedly installed on the surface of the fixed frame 3; a ventilation device 5, the ventilation device 5 being disposed on the inner wall of the ventilation duct 4; an L-shaped frame 6 being fixedly installed at the bottom of the fixed plate 1, a sliding frame 7 being slidably installed at the bottom of the L-shaped frame 6, an arc-shaped scraper 8 being fixedly installed on the surface of the sliding frame 7, a connecting plate 9 being fixedly installed at the bottom of the fixed frame 3, a short plate 10 being fixedly installed on the surface of the connecting plate 9, a short rod 11 being fixedly installed on the side of the short plate 10 near the sliding frame 7, a guide groove being opened on the surface of the sliding frame 7, a rotating shaft 12 being rotatably installed on the inner wall of the guide groove, and a rotating plate 13 being fixedly installed on the surface of the rotating shaft 12 to prevent the filter screen from being continuously scraped during the reset process, causing dust to be pushed to the ground by the arc-shaped scraper 8, affecting the cleanliness of the ground.

[0020] A first spring is provided between the L-shaped frame 6 and the sliding frame 7. The surface of the sliding frame 7 is driven by the elastic force of the first spring. A first torsion spring is provided between the guide groove and the rotating shaft 12. The rotating shaft 12 is reset by the elastic force of the first torsion spring. The rotating plate 13 contacts the inner wall of the guide groove.

[0021] In this embodiment, during operation: the ventilation device 5 rotates to ventilate the interior of the building. When a large amount of dust adheres to the ventilation duct 4, the electric telescopic plate 2 is activated. The downward movement of the output end of the electric telescopic plate 2 drives the fixed frame 3, the ventilation duct 4, and the ventilation device 5 to move downward. The downward movement of the ventilation device 5 can adjust its height, improving the ventilation effect at the bottom of the building. Simultaneously, when the ventilation duct 4 moves downward, the filter screen on its surface will contact the arc-shaped scraper 8. The arc-shaped scraper 8 will scrape off the dust and impurities adhering to the filter screen, preventing dust from clogging the filter screen and affecting the ventilation effect. At the same time, when the fixed frame 3 moves downward, it will drive the connecting plate 9 and the short plate 10 to move downward. The downward movement of the short plate 10 will drive the short rod 11 to move downward. The short rod 11 will move downward along the guide groove. During the downward movement of the short rod 11, it will contact... When the rotating plate 13 is reached, the short rod 11 will push the rotating plate 13 and the rotating shaft 12 to rotate downwards. After the short rod 11 disengages from the rotating plate 13, the first torsion spring will drive the rotating shaft 12 and the rotating plate 13 to reset. The reset rotating plate 13 will abut against the inner wall of the guide groove. Subsequently, when the electric telescopic plate 2 drives the fixed frame 3, the connecting plate 9, the short plate 10 and the short rod 11 to move upwards, the short rod 11 will slide along the inclined surface of the guide groove due to the obstruction of the rotating plate 13. The short rod 11 pushes the sliding frame 7 to move away from the ventilation duct 4. The movement of the sliding frame 7 away from the ventilation duct 4 will drive the arc-shaped scraper 8 to move away from the ventilation duct 4. The movement of the arc-shaped scraper 8 away from the ventilation duct 4 will disengage it from the filter screen, preventing continuous scraping of the filter screen during the reset process, which would cause dust to be directly pushed to the ground by the arc-shaped scraper 8, affecting the cleanliness of the ground.

[0022] Please see Figure 1 - Figure 7 Based on the above embodiments, in another embodiment of the present invention, the sliding frame 7 is provided with a dust collection device and a dust discharge device. The dust collection device includes a long plate 141, a toothed plate 142, a rotating plate 143, a limiting plate 144, and an L-shaped plate 145. The L-shaped plate 145 is fixedly installed on the surface of the sliding frame 7, the long plate 141 is fixedly installed on the surface of the L-shaped plate 145, the toothed plate 142 is fixedly installed on the surface of the long plate 141, the rotating plate 143 is rotatably installed on the top of the arc-shaped scraper 8, and the limiting plate 144 is fixedly installed on the top of the arc-shaped scraper 8. By vibration, the impurities adhering to the inner wall of the arc-shaped scraper 8 are shaken off, preventing the impurities from adhering to the arc-shaped scraper 8 and affecting the subsequent scraping effect.

[0023] A push plate 146 is fixedly installed on the side of the L-shaped plate 145 near the arc-shaped scraper 8. The push plate 146 is slidably connected to the inner wall of the sliding frame 7. A collection frame 147 is fixedly installed at the bottom of the sliding frame 7 to prevent impurities from floating in the air, which would lead to poor air quality and affect the user's breathing.

[0024] A second torsion spring is provided between the rotating plate 143 and the arc-shaped scraper 8. The rotating plate 143 is reset by the elastic force of the second torsion spring itself. A second spring is provided between the push plate 146 and the sliding frame 7. The push plate 146 is reset by the elastic force of the second spring itself.

[0025] In this embodiment, during operation: the sliding frame 7 moves away from the ventilation duct 4, causing the rotating plate 143 to move away from the ventilation duct 4. As the rotating plate 143 moves away from the ventilation duct 4, it comes into contact with the toothed plate 142. When the toothed plate 142 contacts the rotating plate 143, the rotating plate 143 is stopped by the limiting plate 144, causing the toothed plate 142 to vibrate. This vibration shakes off impurities adhering to the inner wall of the arc-shaped scraper 8, preventing impurities from adhering to the arc-shaped scraper 8 and affecting subsequent scraping effects. Simultaneously, when the toothed plate... After 142 is reset, the toothed plate 142 will push the rotating plate 143 to rotate away from the limiting plate 144. Without the limiting plate 144, the rotating plate 143 will not vibrate with the toothed plate 142, preventing long-term vibration from causing severe wear on the surface of the toothed plate 142 and affecting the service life of the equipment. At the same time, when the sliding frame 7 moves away from the ventilation duct 4, the push plate 146 will push the impurities that fall into the sliding frame 7 into the collection frame 147 to recover the impurities and prevent them from floating in the air, causing air quality deterioration and affecting the user's breathing.

[0026] The discharge device includes a fixed block 151, a rotating plate 152, and a square plate 153. The fixed block 151 is fixedly installed on the surface of the push plate 146, the rotating plate 152 is rotatably installed on the inner wall of the collection frame 147, and the square plate 153 is fixedly installed on the top of the rotating plate 152 to prevent dust from drifting out from inside the collection frame 147, causing dust to re-adhere to the filter screen and affect the ventilation effect.

[0027] A push plate 154 is fixedly installed at the bottom of the rotating plate 152. A sliding plate 155 is slidably installed on the inner wall of the collection frame 147. A sealing slide plate 156 is fixedly installed on the surface of the sliding plate 155. A water inlet pipe 157 is connected to the surface of the collection frame 147. A water tank is provided at the top of the water inlet pipe 157. A water outlet 158 ​​is fixedly installed at the end of the collection frame 147 away from the water inlet pipe 157 to prevent dust from being stirred up and affecting the dust removal effect. At the same time, the dust will be discharged from the water outlet 158 ​​along with the water to prevent the dust from accumulating in the collection frame 147 and affecting the dust removal effect.

[0028] A third torsion spring is provided between the rotating plate 152 and the collecting frame 147. The rotating plate 152 is reset by the elastic force of the third torsion spring. A third spring is provided between the collecting frame 147 and the sliding plate 155. The sliding plate 155 is reset by the elastic force of the third spring.

[0029] The movement of the collection frame 147 away from the ventilation duct 4 causes the rotating plate 152 to move away from the ventilation duct 4. This movement of the rotating plate 152 causes the square plate 153 to contact the fixing block 151. The fixing block 151 then pushes the square plate 153 downwards. This downward rotation of the square plate 153 causes the rotating plate 152 to rotate downwards, opening the top of the collection frame 147 and allowing dust to fall into it. When the rotating plate 152 returns to its original position, it seals the collection frame 147, preventing dust from escaping and re-adhering to the filter screen, thus affecting ventilation. When the rotating plate 152 rotates downward, it will drive the pushing plate 154 to rotate downward. The downward rotation of the pushing plate 154 will push the sliding plate 155 to move away from the pushing plate 154. The movement of the sliding plate 155 away from the pushing plate 154 will drive the sealing plate 156 to move away from the pushing plate 154. The movement of the sealing plate 156 away from the pushing plate 154 will overlap with the water inlet pipe 157, allowing the water inside the water inlet pipe 157 to enter the collection frame 147. The water will suppress the dust and prevent the dust from being stirred up, thus affecting the dust suppression effect. At the same time, the dust will be discharged from the water outlet 158 ​​along with the water, preventing the dust from accumulating in the collection frame 147 and affecting the dust removal effect.

[0030] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
