Description

Technical Field

[0001] This invention relates to the field of air conditioning unit technology, specifically a special air conditioning unit for grain storage that is airtight and corrosion resistant, designed for use in marine high-salt-spray corrosion environments. Background Technology

[0002] Marine high-salt-spray corrosion environment refers to a special environment in the ocean and coastal areas where salt spray, formed by a large amount of sodium chloride particles in the air, has a strong corrosive effect on metal materials. Therefore, in grain warehouses in coastal areas, a special air conditioning equipment with airtightness, anti-corrosion properties, and the ability to precisely control the temperature and humidity inside the warehouse is often used to ensure the quality stability of grain during storage and to adapt to the special environment of the grain warehouse.

[0003] Traditional air conditioning units are typically installed by first mounting a bracket on the outer wall of the grain silo, and then using a forklift to lift the air conditioning unit onto the bracket. In order to align the air conditioning unit's connecting pipe with the air inlet on the wall, the air conditioning unit is usually supported by the forks of the forklift, and the position of the connecting pipe is adjusted by lifting, lowering and moving the forklift back and forth. Therefore, it requires the operator to observe visually, resulting in low operational precision, difficulty in quick alignment, low installation efficiency, and forklifts are easily limited by space, making them impractical.

[0004] If the air conditioning unit is damaged during use and needs repair, a ladder is usually used to climb to the vicinity of the air conditioner, and then a screwdriver is used to remove the protective plate. However, the removed protective plate is usually placed directly on the air conditioner casing, which is easy to fall off under external force, posing a safety hazard. Alternatively, someone else may take it to the ground, which requires repeatedly taking the protective plate. The operation process is cumbersome, and the bolts need to be repeatedly removed and removed during installation, resulting in low operation efficiency.

[0005] When repairing air conditioners in the rain, repairmen often have to work in the rain or operate with an umbrella. Because air conditioners are installed in high positions, it is inconvenient to perform repairs, which poses a safety hazard. In addition, rainwater dripping can easily flow into the air conditioner during repairs, causing short circuits in the internal wiring and reducing its practicality. Summary of the Invention

[0006] To address the problems in the existing technology, this invention provides a special airtight, corrosion-resistant air conditioning unit for grain silos designed for use in marine high-salt-spray corrosion environments.

[0035] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0036] like Figure 1 , Figures 4-10As shown, the present invention discloses a special air-tight anti-corrosion air conditioning unit for grain silos in a high-salt-spray corrosive marine environment, comprising an air conditioning body 1, a retractable structure 2 disposed on the air conditioning body 1, and a limiting structure 3 connected to the retractable structure 2. When the air conditioner is being maintained, to avoid the door panel 208 occupying space or being difficult to store, the door panel 208 can be retracted into the interior of the air conditioning body 1. The retractable structure 2 includes a slide rail 201 and a slide rod 202 fixedly connected to the slide rail 201. The two slide rails 201 are symmetrically arranged. A first tension spring 204 is fixedly connected between the slide seat 203 and the inner wall of the slide rail 201. Torsion springs 209 are fixedly connected to the two ends of the rotating seat 207 respectively between them and the adjacent telescopic plates 206. Simply release the restriction on the bottom of the door panel 208, hold the handle on the door panel 208 with one hand, and the rotating seat 207 will slowly rotate upwards under the force of the two torsion springs 209 until the door panel 208 rotates to the position of the air conditioner. With the main body 1 in a vertical position, the door panel 208 remains parallel to the telescopic plate 206. Two slide rails 201 are fixedly connected inside the air conditioner main body 1. A slide block 203 is slidably connected to the slide rod 202, and the slide block 203 is slidably connected to the slide rails 201. A connecting sleeve 205 is engaged with the slide block 203, and the telescopic plate 206 is slidably connected to the connecting sleeve 205. Then, the door panel 208 is pushed inward, causing the door panel 208 to move the telescopic plate 206 and the connecting rod 206. The 5-way connecting sleeve 205 slides inward, while the slide block 203 slides inward along the slide rod 202 and slide rail 201 under the reset action of the first tension spring 204. Then, the slide block 203 drives the door panel 208 to retract into the air conditioner body 1 until it retracts to a suitable length. At this time, the door panel 208 is stored, avoiding the problem of the door panel 208 occupying space or falling off during maintenance. It is highly flexible. When it is necessary to close the door panel 208 again, it can be done by simply reversing the operation, which is simple to operate.

[0037] Specifically, such as Figure 6 and Figure 9As shown, the limiting structure 3 includes a limiting strip 301, which is slidably connected to the slide block 203. The limiting strip 301 is slidably connected to the connecting sleeve 205. The slide rod 202 has multiple insertion holes 303, and the limiting strip 301 engages with the insertion holes 303. A connecting rod 305 is fixedly connected to the telescopic plate 206, and a driving strip 306 is fixedly connected to the connecting rod 305. Both the connecting rod 305 and the driving strip 306 are slidably connected to the connecting sleeve 205. A driving groove 304 is provided on the limiting strip 301, and the driving strip 306 slides in conjunction with the driving groove 304. The connecting rod 305 drives the driving strip 306 to slide inward. At this time, the driving strip 306 and the inclined surface inside the driving groove 304... The sliding engagement between the two telescopic plates 206 causes the limiting strip 301 to slide down and stretch the second tension spring 302. A rotating seat 207 is rotatably connected between the two telescopic plates 206. A door panel 208 is fixedly connected to the rotating seat 207. The cross-sections of the limiting strip 301 and the connecting rod 305 are both T-shaped. The top of the limiting strip 301 has an inclined surface. The bottom of the limiting strip 301 is fixedly connected to the bottom surface of the slide block 203. The insertion hole 303 is slidably engaged with the inclined surface at the top of the limiting strip 301. A first spring 307 is fixedly connected between the end of the connecting rod 305 near the driving strip 306 and the inner wall of the connecting sleeve 205. The connection continues until the top of the limiting strip 301 slides out of the insertion hole 303 and contacts the limiting position of the slide block 203.

[0038] Specifically, such as Figure 5 and Figure 9As shown, a rotating structure 4 is installed on one of the telescopic plates 206. The rotating structure 4 includes a push bar 401 and a locking block 402 fixedly connected to the push bar 401. During maintenance in rainy weather, the door panel 208 can be pulled outwards a certain distance and then rotated at a certain angle to provide rain protection. A push bar 401 is slidably connected to one end of the telescopic plate 206 near the rotating seat 207. A second spring 403 is fixedly connected between the end of the push bar 401 and the telescopic plate 206. The locking block 402 is connected to the hole at the end of the rotating seat 207. The holes interlock with each other. A stop block 404 is slidably connected to the bottom of another telescopic plate 206. A third spring 405 is fixedly connected between the stop block 404 and the telescopic plate 206. The stop block 404 has a beveled surface on its outer side. The locking block 402 has a hexagonal structure. Simply unlock the bottom of the door panel 208, allowing the door panel 208 to rotate perpendicular to the air conditioner body 1 under the force of the torsion spring 209. Then, pull the handle on the door panel 208 outwards. The door panel 208 drives the rotating seat 207 to move outwards, and the rotating seat 207 drives the two telescopic plates 206 outwards. During the sliding motion, the telescopic plate 206 drives the connecting rod 305 to slide outward along the inner wall of the connecting sleeve 205, compressing the first spring 307. During this process, the inclined surface on the stop block 404 slides into the inner wall of the air conditioner body 1, causing the stop block 404 to retract into the telescopic plate 206 until it slides to the outer side of the air conditioner body 1. Under the force of the third spring 405, the stop block 404 pops outward, while the telescopic plate 206, under the elastic force of the first spring 307, drives the stop block 404 to press against the outer wall of the air conditioner body 1. At this point, the rotary seat 207 has completely moved to the air conditioner body 1. The outer side allows the door panel 208 to be rotated to any angle. Then, press the push bar 401 at the other end of the turntable 207 with your finger. The push bar 401 compresses the second spring 403, and the push bar 401 drives the hexagonal locking block 402 to slide into the drain groove 501 until the locking block 402 is no longer engaged with the end of the turntable 207. Then the door panel 208 can be rotated to the specified angle. The flipped door panel 208 can then serve as a rain cover, which is very practical. When it is necessary to retract the door panel 208 into the air conditioner body 1, simply press the stop block 404 and repeat the above operation in reverse. The operation is simple.

[0039] Specifically, such as Figure 1 and Figures 5-10As shown, a drainage structure 5 is fitted onto the rotating base 207. The drainage structure 5 includes a drainage groove 501 and multiple water inlet holes 502 communicating with the drainage groove 501. The drainage groove 501 is located at the center of the rotating base 207. The water inlet holes 502 are located at the top of the door panel 208. A water collection groove 505 is located on the door panel 208. The water inlet holes 502 and the water collection groove 505 are interconnected. A drain pipe 503 is engaged on the air conditioner body 1. Two rubber clamps are engaged on one end of the drain pipe 503 near the rotating base 207. One of the rubber heads 504 has its end face abutting against the pivot 207. When the door panel 208 is in a rain-shielding function, the pivot 207 is in an outward-extending state, and its end is tightly pressed against the outer rubber head 504. This allows the drainage channel 501 to connect to the side drainage pipe 503 via the rubber head 504. The drainage pipe 503 and the drainage channel 501 are connected via the rubber head 504, and the other end of the drainage pipe 503 is connected to an external pipe. Rainwater dripping onto the door panel 208 will slide along the slope. The water flows to the bottom of the water collection tank 505, then through the inlet hole 502 at the bottom of the water collection tank 505 into the drain tank 501, then through the rubber head 504 into the drain pipe 503, and finally out through the pipe at the other end of the drain pipe 503, thus achieving a good drainage effect and preventing rainwater from flowing into the air conditioner body 1 along the door panel 208. At the same time, the air conditioner body 1 is made of a steel frame connected by welding or bolts. The joints are eliminated by continuous welding (such as carbon dioxide gas shielded welding) to prevent gas leakage. The bolted joints are reinforced with anti-aging materials. The nitrile rubber sealing ring is tightened evenly with a torque wrench to ensure a tight seal. A groove is reserved at the contact point between the outer panel and the frame of the air conditioner body 1, and a foamed silicone strip is embedded in it to completely fill the gap and form the first seal. The pipeline holes on the outer shell adopt a stepped sealing structure. First, a metal bellows is installed (to reduce the sealing failure caused by vibration), then the gap is filled with fireproof sealant, and finally the rubber sealing ring is installed and tightened to prevent dust and gas from seeping in through the opening, effectively preventing the intrusion of corrosive media such as high salt spray in the ocean and fumigation gas in grain silos.

[0040] Specifically, such as Figure 1 , Figure 2 and Figure 4As shown, the bottom of the air conditioner body 1 is provided with an installation structure 6. The installation structure 6 includes a mounting bracket 601 and two sliding sleeves 602 disposed on the mounting bracket 601. The bottom of the air conditioner body 1 is provided with two mounting brackets 601. The air conditioner body 1 is installed between two sliding plates 607 via a base 608. Then, with the help of a forklift, the forks are inserted between the top plate 611 and the bottom surface of the air conditioner body 1. The air conditioner body 1 is lifted to the vicinity of the installation position by moving the forks upward. Then, the two mounting brackets 601 are fixed to the outer wall of the grain silo by expansion bolts. At this time, the air conditioner body 1 is quickly installed on the wall. Rollers 603 are rotatably connected to the sliding sleeves 602. A rolling connection is established between the mounting bracket 601 and the air conditioner body 1. A first rack 604 is fixedly connected to the mounting bracket 601, and a second rack 605 is fixedly connected to the sliding sleeve 602. A guide rod 606 is fixedly connected between the two symmetrical sliding sleeves 602, and two sliding plates 607 are slidably connected between the two guide rods 606. Two bases 608 are fixedly connected to the bottom of the air conditioner body 1, and each base 608 is fixedly connected to an adjacent sliding plate 607. A guide post 609 is fixedly connected to one of the mounting brackets 601, and a first knob 610 is rotatably connected to the other mounting bracket 601. A top plate 611 is slidably connected to the guide post 609. The first knob 610 is threadedly connected to the top plate 611, which abuts against the sliding plate 607. Next, the position of the air conditioner body 1 needs to be adjusted to facilitate the connection of the air inlet and outlet ducts on the air conditioner body 1 with the grain silo air vent. Simply rotate the first knob 610, which causes the top plate 611 to move down along the guide post 609 until the roller 603 inside the sliding sleeve 602 abuts against the mounting bracket 601. Then, by pushing the air conditioner body 1 left and right, the sliding plate 607 at the bottom of the air conditioner body 1 slides laterally along the guide rod 606. Simultaneously, by pushing the air conditioner body 1 back and forth, the air conditioner body 1 moves back and forth along the mounting bracket 601 via the four rollers 603. The air inlet and outlet pipes on the back of the air conditioner body 1 are aligned with the air vents of the grain bin. Then, the first knob 610 is rotated in the opposite direction. The first knob 610 drives the top plate 611 to move upward and abut against the sliding plate 607. At this time, the sliding plate 607 can no longer slide laterally along the guide rod 606. At the same time, the sliding plate 607 drives the two pairs of sliding sleeves 602 to move upward through the guide rod 606. The sliding sleeves 602 drive the second rack 605 at the bottom to move upward until the second rack 605 and the first rack 604 mesh with each other. Then, the air conditioner body 1 can no longer move back and forth through the sliding sleeves 602. At this time, the position of the air conditioner body 1 is fixed, which is very firm. At the same time, the position of the air conditioner body 1 can be adjusted during installation, which is very flexible.

[0041] Specifically, such as Figure 1 , Figure 3 and Figure 4As shown, the air conditioner body 1 is equipped with a docking structure 7, which includes a docking pipe 701 and a first sleeve 702 slidably connected to the docking pipe 701. After the overall installation of the air conditioner body 1 is completed, the air inlet and outlet of the air conditioner body 1 need to be docked with the air outlet of the grain silo. First, adjust the extension distance of the first sleeve 702 and the second sleeve 703 according to the distance between the air conditioner body 1 and the outer wall of the grain silo. Two docking pipes 701 are fixedly connected to the air conditioner body 1, and two fiber meshes 706 are fixedly connected to the air conditioner body 1. The ends of the docking pipes 701... A metal wire mesh 705 is fixedly connected to the first sleeve 702. A second sleeve 703 is slidably connected to the inner side of the first sleeve 702. A second knob 704 is threaded to both ends of the first sleeve 702. The two second knobs 704 respectively abut against the connecting tube 701 and the second sleeve 703. By simply pulling the first sleeve 702 and the second sleeve 703 on the two connecting tubes 701 outward, and then rotating the second knobs 704 after pulling them out to a suitable distance, the two second knobs 704 are pressed tightly against the outer walls of the first sleeve 702 and the second sleeve 703, thus achieving the desired effect. The overall length is adjusted, and finally, the second sleeve 703 is connected to the air vent pipe of the grain silo using a clamp. The operation is simple. During operation, the gas flowing inside the pipe will pass through the metal wire mesh 705 and the fiber mesh 706. The metal wire mesh 705 can effectively intercept impurities such as dust, microorganisms, and insects in the air, preventing them from entering the grain silo and contaminating the grain. The fiber mesh 706 can intercept and absorb fine dust and some salt spray aerosols, preventing unfiltered salt spray air from directly seeping into the grain silo or the air conditioner. Furthermore, the outer shell and sealing components of the air conditioner body 1 are made of high-temperature and corrosion-resistant materials. Made of PVC material, it forms a special airtight structure that effectively prevents the intrusion of corrosive media such as high salt spray from the ocean and fumigation gases in grain silos. The outer shell adopts the C5 anti-corrosion design standard, ensuring overall anti-corrosion performance and providing a good protective environment for internal precision components. Meanwhile, the evaporator, condenser and other parts installed on the air conditioner body 1 are made of special materials that can effectively resist phosphine corrosion. An anti-phosphine corrosion coating is applied to the surface of the evaporator to further enhance its corrosion resistance. The condenser uses a copper finned copper tube heat exchanger to improve salt spray resistance.

[0042] In use, the air conditioner body 1 is installed between two sliding plates 607 via a base 608. Then, using a forklift, the forks are inserted between the top plate 611 and the bottom surface of the air conditioner body 1. The air conditioner body 1 is lifted to the vicinity of the installation position by moving the forks upwards. Then, the two mounting brackets 601 are fixed to the outer wall of the grain silo using expansion bolts. At this point, the air conditioner body 1 is quickly installed on the wall. Next, the position of the air conditioner body 1 needs to be adjusted to facilitate the connection of the air inlet and outlet pipes on the air conditioner body 1 with the grain silo's air vents. Simply turn the first knob 610, which moves the top plate 611 down along the guide post 609 until the roller 603 inside the sliding sleeve 602 contacts the mounting bracket 601. Then, by pushing the air conditioner body 1 left and right, the sliding plate 607 at the bottom of the air conditioner body 1 moves horizontally along the guide rod 606. The air conditioner body 1 is slid forward and backward, and simultaneously pushed forward and backward by the four rollers 603. This allows the air conditioner body 1 to move back and forth along the mounting bracket 601 until the air inlet and outlet pipes on the back of the air conditioner body 1 are aligned with the air vents of the grain bin. Then, the first knob 610 is rotated in the opposite direction. The first knob 610 drives the top plate 611 to move upward and abut against the sliding plate 607. At this time, the sliding plate 607 can no longer slide laterally along the guide rod 606. At the same time, the sliding plate 607 drives the two pairs of sliding sleeves 602 to move upward through the guide rod 606. The sliding sleeves 602 drive the second rack 605 at the bottom to move upward until the second rack 605 and the first rack 604 mesh with each other. Thus, the air conditioner body 1 can no longer move back and forth through the sliding sleeves 602. At this time, the position of the air conditioner body 1 is fixed, which is very firm. At the same time, the position of the air conditioner body 1 can be adjusted during installation, which is very flexible.

[0043] After completing the overall installation of the air conditioner body 1, the air inlet and outlet of the air conditioner body 1 need to be connected to the air outlet of the grain silo. First, adjust the extension distance of the first sleeve 702 and the second sleeve 703 according to the distance between the air conditioner body 1 and the outer wall of the grain silo. Simply pull the first sleeve 702 and the second sleeve 703 on the two connecting pipes 701 outwards. After pulling them out to the appropriate distance, turn the second knob 704 so that the two second knobs 704 are respectively pressed against the outer wall of the first sleeve 702 and the second sleeve 703. At this time, the overall length adjustment is achieved. Finally, use the clamp to connect the second sleeve 703 to the air outlet pipe of the grain silo. The operation is simple, and at the same time, the gas flowing inside the pipe will pass through Through the metal wire mesh 705 and fiber mesh 706, the metal wire mesh 705 can effectively intercept impurities such as dust, microorganisms, and insects in the air, preventing them from entering the grain silo and contaminating the grain. The fiber mesh 706 can intercept and adsorb fine dust and some salt spray aerosols, preventing unfiltered salt spray air from directly infiltrating into the grain silo or the air conditioner. Furthermore, since the outer shell and sealing components of the air conditioner body 1 are made of high-temperature resistant and corrosion-resistant PVC material, a special airtight structure is formed. At the same time, the air conditioner body 1 adopts a steel frame connected by welding or bolts. The joints are eliminated by continuous welding (such as carbon dioxide gas shielded welding) to prevent gas leakage. The bolted joints are reinforced with aging-resistant nitrile rubber. The rubber sealing ring is tightened evenly with a torque wrench to ensure a tight seal. A groove is pre-drilled at the contact point between the outer panel and the frame of the air conditioner body 1, into which a foamed silicone strip is embedded, completely filling the gap to form the first seal. The pipe holes on the outer casing adopt a stepped sealing structure: first, a metal bellows is installed (to reduce seal failure caused by vibration), then fire-retardant sealant is used to fill the gaps, and finally, a rubber sealing ring is installed and tightened to prevent dust and gas from seeping in through the openings. This effectively prevents the intrusion of corrosive media such as high-salt spray from the ocean and fumigation gases from grain silos. Furthermore, the outer casing adopts the C5 anti-corrosion design standard, ensuring overall anti-corrosion performance and providing a good protective environment for internal precision components. Simultaneously, it is installed in the air conditioner... The evaporator, condenser, and other components on the main body 1 are made of special materials that can effectively resist phosphine corrosion. The evaporator fins are made of corrosion-resistant aluminum-manganese alloy, and the copper tubes are made of internally threaded copper tubes. The surface of the copper tubes is annealed to reduce stress corrosion and ensure that the fins and copper tubes are in close contact to improve heat exchange efficiency. An anti-phosphine corrosion coating is applied to the surface of the evaporator to further enhance its corrosion resistance. The condenser uses a copper fin-coated copper tube heat exchanger to improve salt spray resistance. The fins and copper tubes are coated with polyvinylidene fluoride, which has strong salt spray resistance and self-cleaning function. The outer shell is made of hot-dip galvanized steel plate, which has excellent resistance to pitting and crevice corrosion and is suitable for C5 environment.

[0044] When repairing the air conditioner, to avoid the door panel 208 taking up space or being difficult to store, the door panel 208 can be retracted into the air conditioner body 1. Simply release the restriction on the bottom of the door panel 208, hold the handle on the door panel 208 with one hand, and the rotating seat 207 will slowly rotate upward under the force of the two torsion springs 209 until the door panel 208 rotates to a position perpendicular to the air conditioner body 1. At this time, the door panel 208 remains parallel to the telescopic plate 206. Then push the door panel 208 inward, and the door panel 208 will drive the telescopic plate 206 and the connecting rod 305 to slide inward toward the connecting sleeve 205. The connecting rod 305 will drive the drive bar 306 to slide inward. At this time, the drive bar 306 slides and engages with the inclined surface inside the drive groove 304, causing the limit bar 301 to slide down and stretch the second tension spring 302 until the top of the limit bar 301 slides out of the insertion hole 303. Under the reset action of the first tension spring 204, the slide block 203 slides inward along the slide rod 202 and the slide rail 201. Then, the slide block 203 drives the door panel 208 to retract into the air conditioner body 1 until it retracts to a suitable length. At this time, the door panel 208 is stored, avoiding the problem of the door panel 208 occupying space or falling off during maintenance. It is highly flexible. When it is necessary to close the door panel 208 again, it is only necessary to reverse the operation, which is simple to operate.

[0045] If maintenance is to be performed in rainy weather, the door panel 208 can be pulled outwards a certain distance and then rotated at a certain angle to provide rain protection. Simply unlock the bottom of the door panel 208, allowing it to rotate under the force of the torsion spring 209 until it is perpendicular to the air conditioner body 1. Then pull the handle on the door panel 208 outwards. The door panel 208 moves the rotating seat 207 outwards, which in turn moves the two telescopic plates 206 outwards. At this time, the telescopic plates 206 move the connecting rod 305 outwards along the inner wall of the connecting sleeve 205, compressing the first spring 307. During this process, the inclined surface on the stop block 404 slides against the inner wall of the air conditioner body 1, causing the stop block 404 to retract into the telescopic plate 206 until it slides to the outside of the air conditioner body 1. 4. Under the force of the third spring 405, it pops outward. At the same time, under the elastic force of the first spring 307, the telescopic plate 206 drives the stop block 404 to press against the outer wall of the air conditioner body 1. At this time, the rotating seat 207 moves completely to the outside of the air conditioner body 1, making it easy to rotate the door panel 208 to any angle. Then, press the push bar 401 at the other end of the rotating seat 207 with your finger. The push bar 401 compresses the second spring 403, and the push bar 401 drives the hexagonal locking block 402 to slide into the drain groove 501 until the locking block 402 is no longer engaged with the end of the rotating seat 207. Then, the door panel 208 can be rotated to the specified angle. The flipped door panel 208 can then serve as a rain cover. It is highly practical. When it is necessary to retract the door panel 208 into the air conditioner body 1, simply press the stop block 404 and repeat the above operation in reverse. The operation is simple.

[0046] When the door panel 208 is used for rain protection, the rotating seat 207 is in an outward-extending state, and the end of the rotating seat 207 is in close contact with the outer rubber head 504. As a result, the drainage groove 501 can be connected to the side drainage pipe 503 through the rubber head 504. Rainwater dripping on the door panel 208 will slide along the slope to the bottom of the water collection groove 505, and then flow from the water inlet 502 at the bottom of the water collection groove 505 into the drainage groove 501. Then it flows through the rubber head 504 into the drainage pipe 503, and finally is discharged outward through the pipe at the other end of the drainage pipe 503. This achieves a good drainage effect and prevents rainwater from flowing into the air conditioner body 1 along the door panel 208.
