Description

Technical Field

[0001] This invention relates to the field of protective rack technology, specifically a caustic soda protective rack. Background Technology

[0002] During well site construction, caustic soda was arbitrarily scattered on trays without any protective facilities. To protect the caustic soda used at the well site and prevent unauthorized personnel from taking it, a protective frame needs to be installed around the caustic soda. However, traditional protective frames are made of spliced ​​wire mesh panels, but caustic soda must be protected from light. If it is exposed to light, it will affect the quality of the caustic soda. These wire mesh panels do not provide adequate light protection. Furthermore, the well site is a construction area with no rain protection measures, so the wire mesh protective frame is ineffective in protecting against rain. If a protective frame made of solid panels were used, it could provide better protection for the caustic soda. Caustic soda serves to protect against light and rain. However, to ensure proper air circulation and prevent internal temperature rise, ventilation openings are typically provided on the side of the solid panel. While the height of these openings is usually fixed, different pallets may have different heights. If the pallet and the ventilation opening are not at the same height, poor air circulation around the pallet will result in increased temperature around the pallet (caustic soda deteriorates after 35 degrees Celsius). If the temperature exceeds 35 degrees Celsius, it will affect the quality of the caustic soda, causing it to deteriorate and leading to waste. Therefore, those skilled in the art have proposed a caustic soda protective rack. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a caustic soda protective rack. The height of the square frame used for ventilation in this device can be adjusted to be at the same height as the tray, thus solving the problem of poor air circulation around the caustic soda caused by the large distance between the tray and the ventilation opening mentioned above.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a caustic soda protection rack, comprising a side plate mechanism, a front plate mechanism, a rear plate mechanism, and a top plate mechanism. The front plate mechanism is disposed between the side plate mechanisms, the rear plate mechanism is disposed between the side plate mechanisms and located on one side of the front plate mechanism, and the top plate mechanism is disposed on the side plate mechanisms. All the mechanisms together form the caustic soda rack. It should be noted that the side plate mechanism includes a movable square frame and a drive assembly connected thereto. By rotating the knob to drive the drive assembly, the square frame can be moved up and down, thereby adjusting the height of the frame to be at the same height as the caustic soda tray to be protected. As a further technical solution of the present invention, the side plate mechanism includes two orifice-shaped frames, each orifice-shaped frame having a side plate installed on its inner side, each side plate having a moving groove on its side, each moving groove having a square frame slidably installed in its moving groove, each moving groove having several evenly distributed anti-theft bars installed on one side of the square frame, each orifice-shaped frame having a storage groove in its transverse plate, each storage groove having a take-up roller rotatably installed in its storage groove, each upper take-up roller having an upper curtain wound around it, each lower take-up roller having a lower curtain wound around it, each lower curtain having one side extending into the moving groove and fixedly connected to the lower surface of the square frame, and each upper curtain having one side extending into the moving groove and fixedly connected to the upper surface of the square frame.

[0005] As a further technical solution of the present invention, each of the orifice-shaped frames has a cavity on one side of each storage slot, and each of the longitudinal plates of each orifice-shaped frame has a first movable slot.

In each group, one of the mounting plates extends through the upper curtain into the first movable slot and is fixedly connected to the threaded seat, and the other mounting plate extends through the upper curtain into the other first movable slot and is fixedly connected to the slider.

[0006] As a further technical solution of the present invention, one end of the screw in each of the orifice frames extends into the upper cavity and the other end extends into the lower cavity. One end of each of the take-up rollers extending into the cavity is equipped with a second conical tooth. A first conical tooth that meshes with the second conical tooth is installed on the surface of the screw in each cavity. A third conical tooth is installed on the surface of each screw near the lower part. A fourth conical tooth that meshes with the third conical tooth is rotatably installed on the inner wall of each corresponding first moving groove. One end of each fourth conical tooth extends to the outside of the orifice frame and is equipped with a knob. An extrusion block is installed on the side of one of the mounting plates on each of the square frames.

[0007] As a further technical solution of the present invention, each of the square frames is hinged with a baffle, each baffle has a first slot inside, each first slot has a first slider slidably installed inside, each first slot has a first spring below the first slider, each square frame has a slot directly above the first slot on its inner top surface, each first slider has a plug extending into the slot at its upper surface center, each baffle has a first strip groove on its side that engages with the first slot, and each first slider has a lever extending through the first strip groove to the outside of the baffle on its side.

[0008] As a further technical solution of the present invention, the rear plate mechanism includes a rear plate located on the rear surface of two orifice frames. An upper ventilation groove is provided on the side of the rear plate, and a lower ventilation groove is provided on the side of the rear plate directly below the upper ventilation groove. A second slot is provided on one side of both the upper and lower ventilation grooves inside the rear plate. A second limiting plate is slidably installed in each second slot. A set of second springs is provided on one side of each second limiting plate in each second slot. A sealing plate extending into and blocking the upper or lower ventilation groove is installed on the other side of each second limiting plate. A second strip groove communicating with each second slot is provided on one side of the rear plate. An L-shaped plate that can slide on the side of the rear plate is installed through the second strip groove on the side of each second limiting plate. A square block is installed at one end of each L-shaped plate.

[0009] As a further technical solution of the present invention, the front plate mechanism includes a front plate, which is disposed on the front surface of two orifice frames. The front plate has a frame door on its side, and two positioning plates are installed on the side of the frame door near the upper end. A set of first pin cylinders is installed on the front and rear surfaces of each orifice frame. A first pin shaft is sleeved on each first pin cylinder. The four first pin shafts at the front are fixedly connected to the front plate, and the four first pin shafts at the rear are fixedly connected to the rear plate.

[0010] As a further technical solution of the present invention, the top plate mechanism includes an upper plate, which is disposed directly above the orifice frame, the rear plate, and the front plate. A set of second pin cylinders is correspondingly provided on one side of the upper surface of each orifice frame, and a second pin shaft is sleeved in each second pin cylinder. Each second pin shaft is fixedly connected to the upper plate.

[0011] Specifically, the following steps are included: S1. Place the two mouth-shaped frames vertically, then place the front plate directly in front of the two mouth-shaped frames, and insert the four first pins of the front plate into the four first pin cylinders on the front surface of the two mouth-shaped frames. Then place the rear plate directly behind the mouth-shaped frames, and insert the four first pins of the rear plate into the four first pin cylinders on the rear surface of the mouth-shaped frames. S2. Place the upper plate above the two orifice frames, the rear plate, and the front plate, and insert the four second pins of the upper plate into the four second pin cylinders on the upper surface of the orifice frames to complete the assembly of the device. Use the upper plate to cover the upper surface of the rear plate and the front plate to limit their movement. At the same time, use the two positioning plates on the side of the frame door to limit the upper plate. When the frame door is locked, the device cannot be disassembled from the outside. S3. Cover the caustic soda tray at the well site with the device. When the tray is above the square frame, rotate the knob to drive the screw to rotate through the fourth and third bevel teeth. The rotating screw drives the threaded seat to rise, thereby driving the square frame to rise through the mounting plate. It also drives the slider to slide on the slide rod through another mounting plate. At the same time, the rotating screw drives the two take-up rollers to rotate in the same direction through the two first and second bevel teeth. When the square frame rises, the upper rotating take-up roller winds the upper curtain, and the lower take-up roller unwinds the lower curtain wound on it until the square frame is on the same plane as the tray. Then rotate the other knob to raise the other square frame to the same height as the tray through the above operation. S4. When the tray is below the square frame, the reverse knob is used to lower the square frame by the above operation, and at the same time, the two winding rollers are reversed. During the descent of the square frame, the lower winding roller is wound around the lower curtain, and the upper winding roller is unwound the upper curtain until the square frame and the tray are at the same height. Then, the above operation is repeated to lower the other square frame to the same height as the tray. When the two square frames and the tray are at the same height, when the outside wind blows into the device from the square frames, since the tray is at the same height as them, the wind can cool the caustic soda on the tray, so as to prevent the caustic soda from overheating and deteriorating. S5. When the square frame moves to the top, the pressing block on the side mounting plate of one of the square frames will lift the upper square block. The L-shaped plate will drive the lower second limiting plate to rise. The rising second limiting plate will compress the second spring and also drive the sealing plate to rise into the second slot, thus opening the lower ventilation slot. This allows outside air to enter the device from the lower ventilation slot and cool the bottom of the device. S6. When the square frame moves to the bottom, the pressing block on the side mounting plate of one of the square frames will press down on the square block below, thereby opening the upper ventilation slot through the above operation. Outside air can enter the device through the upper ventilation slot to cool the top of the device and prevent the temperature from getting higher and higher due to poor ventilation at the top, which would affect the caustic soda. S7. When it rains, rotating the knob moves the square frame to the center position through the above operation, releasing the pressure on the square block. This allows the second spring to rebound and restore the position of the second limiting plate, causing the sealing plate to return to the upper or lower ventilation slot, thus closing the upper or lower ventilation slot. Then, pressing down the lever causes the first slider to descend, compressing the first spring and simultaneously causing the insert to enter the first slot. Rotating the baffle around the hinge causes the insert to align with the slot. Then, releasing the lever allows the first spring to rebound and restore the position of the first slider, causing the insert to be inserted into the slot to fix the baffle and close the square frame, thus preventing rainwater from entering the device through the square frame. Beneficial effects

[0012] This invention provides a caustic soda protective rack. Compared with the prior art, it has the following advantages: 1. A caustic soda protective frame, wherein rotating a knob on the side plate mechanism of the device drives a screw to rotate via a fourth and third bevel gear. The rotating screw drives a threaded seat to rise, which in turn drives a square frame to rise via a mounting plate. Reversing the knob also drives the square frame to fall, thereby adjusting the height of the square frame for ventilation according to the height of the tray. Since the square frame and the tray are at the same height, ventilation of the caustic soda on the tray is ensured, preventing the surrounding temperature of the caustic soda from rising and ensuring the quality of the caustic soda. Simultaneously, during the movement of the frame, when the square frame rises to its highest point, it compresses the upper square block, which opens the lower ventilation slot via a component. When the square frame falls... When the square frame reaches its lowest point, it compresses the lower square block, causing the upper ventilation slot to open via the component. This ensures airflow to the lower part of the device when the square frame is at its highest point, preventing stagnant air from causing temperature rise and affecting the caustic soda. Simultaneously, when the square frame descends to its lowest point, the upper ventilation slot opens, ensuring airflow to the upper part of the device. Furthermore, the device is made entirely of solid panels, providing light protection. The baffles close the directional frame, and when the upper and lower ventilation slots are closed, they provide rain protection. Installation, assembly, and disassembly are safe and quick, and the device is easy to use, effectively preventing unauthorized personnel from taking caustic soda, ensuring safe management.

[0015] 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.

[0016] Please see Figure 1-9This invention provides a caustic soda protection rack technical solution: a caustic soda protection rack includes a side plate mechanism, a front plate mechanism, a rear plate mechanism, and a top plate mechanism. The front plate mechanism is disposed between the side plate mechanisms, the rear plate mechanism is disposed between the side plate mechanisms and on one side of the front plate mechanism, and the top plate mechanism is disposed on the side plate mechanisms. All the mechanisms together form the caustic soda rack. It should be noted that the side plate mechanism includes a movable square frame and a drive assembly connected to it. By rotating the knob to drive the drive assembly, the square frame can be moved up and down, thereby adjusting the height of the frame to be at the same height as the caustic soda tray to be protected. The side plate mechanism includes two orifice-shaped frames 1, and a side plate 2 is installed on the inner side of each orifice-shaped frame 1. Each side plate 2 has a movable opening on its side. Each movable slot 3 has a square frame 4 slidably installed inside it. Inside each movable slot 3, on one side of the square frame 4, are several evenly distributed anti-theft bars 49. Each orifice-shaped frame 1 has a storage slot 5 in its horizontal plate. Each storage slot 5 has a rotating take-up roller 6 rotatably installed inside it. Each upper take-up roller 6 has an upper baffle curtain 25 wound around it, and each lower take-up roller 6 has a lower baffle curtain 24 wound around it. One side of each lower baffle curtain 24 extends into the movable slot 3 and is fixedly connected to the lower surface of the square frame 4. One side of each upper baffle curtain 25 extends into the movable slot 3 and is fixedly connected to the upper surface of the square frame 4. Each orifice-shaped frame 1 has a cavity 7 on one side of each storage slot 5 inside it. Each orifice-shaped frame 1 has a first movable slot 8 in its vertical plate. A screw 9 is rotatably installed in one of the first moving slots 8 within each orifice frame 1. Each screw 9 is equipped with a threaded seat 12. A slide rod 14 is installed in the other first moving slot 8 within each orifice frame 1. A slider 15 is slidably installed on each slide rod 14. An upper baffle 26 is provided on the inner wall of each first moving slot 8. Two mounting plates 16 are correspondingly installed on the side of each square frame 4. In each set, one mounting plate 16 extends through the upper baffle 26 into the first moving slot 8 and is fixedly connected to the threaded seat 12. The other mounting plate 16 extends through the upper baffle 26 into the other first moving slot 8 and is fixedly connected to the slider 15. One end of the screw 9 in each orifice frame 1 extends into the upper cavity 7, and the other end extends into the lower cavity 7. Each take-up roller 6 has a second bevel tooth 11 installed at one end extending into the cavity 7. A first bevel tooth 10, meshing with the second bevel tooth 11, is installed on the surface of the screw 9 within each cavity 7. A third bevel tooth 27 is installed near the bottom of the surface of each screw 9. A fourth bevel tooth 28, meshing with the third bevel tooth 27, is rotatably installed on the inner wall of each corresponding first moving groove 8. One end of each fourth bevel tooth 28 extends to the outside of the orifice frame 1 and is equipped with a knob 29. An extrusion block 40 is installed on the side of one of the mounting plates 16 on each square frame 4. In use, rotating the knob 29 drives the screw 9 to rotate via the fourth bevel tooth 28 and the third bevel tooth 27. The rotating screw 9 drives the threaded seat 12 to rise, thereby causing the square frame 4 to rise via the mounting plate 16.This also causes the slider 15 to slide on the slide rod 14 via another mounting plate 16. Simultaneously, the rotating screw 9 drives the two take-up rollers 6 to rotate in the same direction via two first bevel teeth 10 and two second bevel teeth 11. As the square frame 4 rises, the upper rotating take-up roller 6 winds the upper curtain 25, while the lower take-up roller 6 unwinds the lower curtain 24 wound around it, until the square frame 4 and the tray are on the same plane.

[0017] Please see Figure 1-9 Each square frame 4 has a hinged baffle 17, each baffle 17 has a first slot 18 inside, each first slot 18 has a first slider 19 slidably installed in it, each first slot 18 has a first spring 20 below the first slider 19, each square frame 4 has a slot 50 directly above the first slot 18 on its inner top surface, each first slider 19 has a plug 23 extending into the slot 50 at its center on its upper surface, each baffle 17 has a first strip groove 21 on its side that engages with the first slot 18, and each first slider 19 has a first strip groove 21 on its side that engages with the first slot 18. Each side of the baffle 17 is equipped with a lever 22 that extends through the first strip groove 21 to the outside of the baffle 17. When it rains, pressing down the lever 22 causes the first slider 19 to descend, compressing the first spring 20 and causing the plug 23 to enter the first empty groove 18. The baffle 17 is rotated around the hinge to align the plug 23 with the slot 50. Then, the lever 22 is released to allow the first spring 20 to rebound and cause the first slider 19 to return to its original position, thereby causing the plug 23 to be inserted into the slot 50 to fix the baffle 17 and close the square frame 4, thus preventing rainwater from entering the device from the square frame 4.

[0018] Please see Figure 1-11The rear plate mechanism includes a rear plate 30, which is located on the rear surface of the two orifice frames 1. An upper ventilation slot 31 is formed on the side of the rear plate 30, and a lower ventilation slot 32 is formed directly below the upper ventilation slot 31 on the side of the rear plate 30. A second slot 33 is formed on one side of both the upper and lower ventilation slots 31 and 32 inside the rear plate 30. A second limiting plate 34 is slidably installed in each second slot 33. A set of second springs 35 is provided on one side of each second limiting plate 34 in each second slot 33. A sealing plate 36 extending into and blocking the upper or lower ventilation slot 31 or 32 is installed on the other side of each second limiting plate 34. A second strip groove 37 communicating with each second slot 33 is formed on one side of the rear plate 30. An L-shaped plate 38 that can slide on the side of the rear plate 30 is installed through the second strip groove 37 on the side of each second limiting plate 34. Each L-shaped plate 38 has a square block 39 installed at one end. When the square frame 4 moves to the top, the pressing block 40 on the side mounting plate 16 of one of the square frames 4 will lift the upper square block 39. The L-shaped plate 38 will drive the lower second limiting plate 34 to rise. The rising second limiting plate 34 will compress the second spring 35 and also drive the sealing plate 36 to rise into the second empty groove 33, thus opening the lower ventilation groove 32. This allows outside air to enter the device from the lower ventilation groove 32 to cool the bottom of the device. When the square frame 4 moves to the bottom, the pressing block 40 on the side mounting plate 16 of one of the square frames 4 will press down the lower square block 39. This operation will drive the upper ventilation groove 31 to open, allowing outside air to enter the device from the upper ventilation groove 31 to cool the top of the device and prevent the temperature from rising due to poor ventilation at the top, which could affect the caustic soda.

[0019] Please see Figure 1-4 The front plate mechanism includes a front plate 41, which is disposed on the front surface of the two orifice frames 1. A frame door 42 is provided on the side of the front plate 41. Two positioning plates 43 are installed on the side of the frame door 42 near the upper end. A set of first pin cylinders 44 are installed on the front and rear surfaces of each orifice frame 1. A first pin shaft 45 is fitted on each first pin cylinder 44. The four first pin shafts 45 at the front are fixedly connected to the front plate 41, and the four first pin shafts 45 at the rear are fixedly connected to the rear plate 30. The front plate 41 is assembled with the side plate 1 through the first pin shafts 45 and the first pin cylinders 44. The rear plate 30 is also assembled with the side plate 1 through the first pin shafts 45 and the first pin cylinders 44.

[0020] Please see Figure 1-4The top plate mechanism includes an upper plate 46, which is positioned directly above the orifice frame 1, the rear plate 30, and the front plate 41. A set of second pin cylinders 47 are correspondingly provided on one side of the upper plate 46 on the upper surface of each orifice frame 1. A second pin shaft 48 is fitted inside each second pin cylinder 47. Each second pin shaft 48 is fixedly connected to the upper plate 46. The upper plate 46 is assembled with the side plate 1 through the second pin shafts 48 and the second pin cylinders 47.

[0021] Specifically, the following steps are included: S1. Place the two mouth-shaped frames 1 vertically, then place the front plate 41 directly in front of the two mouth-shaped frames 1, and insert the four first pins 45 of the front plate 41 into the four first pin cylinders 44 on the front surface of the two mouth-shaped frames 1. Then place the rear plate 30 directly behind the mouth-shaped frames 1, and insert the four first pins 45 of the rear plate 30 into the four first pin cylinders 44 on the rear surface of the mouth-shaped frames 1. S2. Place the upper plate 46 above the two orifice frames 1, the rear plate 30, and the front plate 41, and insert the four second pins 48 of the upper plate 46 into the four second pin cylinders 47 on the upper surface of the orifice frame 1, thereby completing the assembly of the device. The upper plate 46 covers the upper surfaces of the rear plate 30 and the front plate 41, thereby limiting their movement. At the same time, the two positioning plates 43 on the side of the frame door 42 limit the upper plate 46. When the frame door 42 is locked, the device cannot be disassembled from the outside. S3. Cover the device outside the caustic soda tray at the well site. When the tray is above the square frame 4, rotate the knob 29 to drive the screw 9 to rotate through the fourth bevel tooth 28 and the third bevel tooth 27. The rotating screw 9 drives the threaded seat 12 to rise, thereby driving the square frame 4 to rise through the mounting plate 16. This also drives the slider 15 to slide on the slide rod 14 through another mounting plate 16. At the same time, the rotating screw 9 drives the two take-up rollers 6 to rotate in the same direction through the two first bevel teeth 10 and the second bevel teeth 11. When the square frame 4 rises, the upper rotating take-up roller 6 winds the upper curtain 25, and the lower take-up roller 6 unwinds the lower curtain 24 wound on it until the square frame 4 is on the same plane as the tray. Then rotate the other knob 29 to raise the other square frame 4 to the same height as the tray through the above operation. S4. When the tray is below the square frame 4, the reverse knob 29 lowers the square frame 4 through the above operation, and at the same time, the two take-up rollers 6 reverse. During the descent of the square frame 4, the lower reverse take-up roller 6 winds the lower curtain 24, and the upper reverse take-up roller 6 unfolds the upper curtain 25 until the square frame 4 is at the same height as the tray. Then, the above operation is repeated to lower the other square frame 4 to the same height as the tray. When the two square frames 4 and the tray are at the same height, when the outside wind blows into the device from the square frame 4, since the tray is at the same height as it, the wind can cool the caustic soda on the tray, so as to prevent the caustic soda from being too hot and deteriorating. S5. When the square frame 4 moves to the top, the pressing block 40 on the side mounting plate 16 of one of the square frames 4 will lift the upper square block 39. The L-shaped plate 38 will drive the lower second limiting plate 34 to rise. The rising second limiting plate 34 will compress the second spring 35 and also drive the sealing plate 36 to rise into the second empty groove 33, so that the lower ventilation groove 32 will open. Thus, the outside wind can enter the device from the lower ventilation groove 32 to cool the bottom of the device. S6. When the square frame 4 moves to the bottom, the pressing block 40 on the side mounting plate 16 of one of the square frames 4 will press down the square block 39 below, thereby opening the upper ventilation slot 31 through the above operation. Outside air can enter the device through the upper ventilation slot 31 to cool the top of the device and prevent the temperature from getting higher and higher due to poor ventilation at the top, which would affect the caustic soda. S7. When it rains, rotating the knob 29 moves the square frame 4 to the center position through the above operation, releasing the pressure on the square block 39. This allows the second spring 35 to rebound and restore the position of the second limiting plate 34, causing the sealing plate 36 to return to the upper ventilation slot 31 or lower ventilation slot 32, thus closing the upper ventilation slot 31 or lower ventilation slot 32. Then, pressing down the lever 22 causes the first slider 19 to descend, compressing the first spring 20 and also causing the plug 23 to enter the first empty slot 18. Rotating the baffle 17 around the hinge causes the plug 23 to align with the slot 50. Then, releasing the lever 22 allows the first spring 20 to rebound and restore the position of the first slider 19, thus causing the plug 23 to insert into the slot 50 to fix the baffle 17 and close the square frame 4, thereby preventing rainwater from entering the device from the square frame 4.

9. A caustic soda protective rack according to claim 8, characterized in that, Specifically, the following steps are included: S1. Place the two mouth-shaped frames (1) vertically, then place the front plate (41) directly in front of the two mouth-shaped frames (1), and insert the four first pins (45) of the front plate (41) into the four first pin cylinders (44) on the front surface of the two mouth-shaped frames (1). Then place the rear plate (30) directly behind the mouth-shaped frame (1), and insert the four first pins (45) of the rear plate (30) into the four first pin cylinders (44) on the rear surface of the mouth-shaped frame (1). S2. Place the upper plate (46) above the two orifice frames (1), the rear plate (30), and the front plate (41), and insert the four second pins (48) of the upper plate (46) into the four second pin cylinders (47) on the upper surface of the orifice frame (1) to complete the assembly of the device. Use the upper plate (46) to cover the upper surfaces of the rear plate (30) and the front plate (41) to limit their movement. At the same time, use the two positioning plates (43) on the side of the frame door (42) to limit the upper plate (46). When the frame door (42) is locked, the device cannot be disassembled from the outside. S3. Cover the device outside the caustic soda tray at the well site. When the tray is above the square frame (4), rotate the knob (29) to drive the screw (9) to rotate through the fourth bevel tooth (28) and the third bevel tooth (27). The rotating screw (9) drives the threaded seat (12) to rise, thereby driving the square frame (4) to rise through the mounting plate (16). This also drives the slider (15) to slide on the slide bar (14) through another mounting plate (16). At the same time, the rotating screw (9) drives the two take-up rollers (6) to rotate in the same direction through the two first bevel teeth (10) and the second bevel tooth (11). When the square frame (4) rises, the upper rotating take-up roller (6) winds the upper curtain (25), and the lower take-up roller (6) unwinds the lower curtain (24) wound on it until the square frame (4) is on the same plane as the tray. Then rotate the other knob (29) to raise the other square frame (4) to the same height as the tray through the above operation. S4. When the tray is below the square frame (4), the reverse knob (29) lowers the square frame (4) by the above operation, and at the same time, the two take-up rollers (6) reverse. During the descent of the square frame (4), the lower reverse take-up roller (6) winds the lower curtain (24), and the upper reverse take-up roller (6) unfolds the upper curtain (25) until the square frame (4) is at the same height as the tray. Then repeat the above operation to lower the other square frame (4) to the same height as the tray. When the two square frames (4) and the tray are at the same height, when the outside wind blows into the device from the square frame (4), since the tray is at the same height as it, the wind can cool the caustic soda on the tray and prevent the caustic soda from being too hot and deteriorating. S5. When the square frame (4) moves to the top, the pressing block (40) on the side mounting plate (16) of one of the square frames (4) will lift the upper square block (39), and drive the lower second limiting plate (34) to rise through the L-shaped plate (38). The rising second limiting plate (34) compresses the second spring (35) and also drives the sealing plate (36) to rise into the second cavity (33) to open the lower ventilation groove (32), so that the outside wind can enter the device from the lower ventilation groove (32) to cool the bottom of the device. S6. When the square frame (4) moves to the bottom, the pressing block (40) on the side mounting plate (16) of one of the square frames (4) will press down the square block (39) below, thereby driving the upper ventilation slot (31) to open through the above operation. Outside air can enter the device through the upper ventilation slot (31) to cool the top of the device and avoid the situation where the temperature of the top ventilation is too high and affects the caustic soda. S7. When it rains, rotating the knob (29) moves the square frame (4) to the center position through the above operation, releasing the pressure on the square block (39), so that the second spring (35) rebounds and drives the second limiting plate (34) to return to its original position, driving the sealing plate (36) back into the upper ventilation groove (31) or lower ventilation groove (32), thereby closing the upper ventilation groove (31) or lower ventilation groove (32). Then, pressing down the toggle block (22) drives the first slider (19) to descend, compressing... The first spring (20) will also drive the plug (23) into the first slot (18). The baffle (17) rotates around the hinge to drive the plug (23) to align with the slot (50). Then, the lever (22) is released to allow the first spring (20) to rebound and drive the first slider (19) to return to its original position, thereby driving the plug (23) to insert into the slot (50) to fix the baffle (17) and close the square frame (4), thereby preventing rainwater from entering the device from the square frame (4).
