Description

Technical Field

[0001] The invention belongs to the technical field of ventilation skylights, in particular to a glass fiber reinforced plastic ventilator. Background Art

[0002] A ventilator is a ventilation device installed on the roof or skylight of a factory building. It is usually divided into two types: natural ventilation and mechanical ventilation. Natural ventilation mainly uses the thermal pressure difference and wind pressure difference inside and outside the factory to drive the natural flow of air. When there is a temperature difference between indoors and outdoors, hot air rises and cold air sinks, forming natural convection, thereby achieving ventilation and reducing the temperature inside the factory.

[0003] In the field of industrial and civil construction, when there is a need to discharge continuous heat sources and highly corrosive chemical media (such as acidic aerosols, alkaline steam, etc.), traditional carbon steel ventilator components are generally supported by carbon steel materials. However, due to the insufficient corrosion resistance of the material itself, structural degradation is prone to occur during long-term contact with corrosive media, resulting in a short service life and the need for frequent replacement, which increases the cost of use.

[0004] Furthermore, in a natural pressure differential ventilator, if there are weather changes such as continuous rainfall, the imbalance of the indoor and outdoor air pressure difference will lead to a decrease in ventilation efficiency. At the same time, the interaction between rainwater and airflow may destroy the anti-seepage ability of the ventilation structure and cause rainwater backflow, which not only affects the ventilation effect, but also causes short circuit and rust problems due to water accumulation or moisture in the equipment. For this reason, the present invention provides a fiberglass ventilator. Summary of the invention

DETAILED DESCRIPTION

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0034] like Figures 1 to 5 As shown, a glass fiber reinforced plastic ventilator according to an embodiment of the present invention comprises a shell 1, two sets of brackets 2 are arranged inside the shell 1, a cover plate 5 is fixedly connected inside the bracket 2, a base 4 is fixedly connected below the shell 1, two sets of movable plates 3 are slidably connected inside the shell 1, and the thickness of the middle position of the two sets of movable plates 3 is different, ventilation holes are opened on both sides of the shell 1, and an adjustment component is arranged below the cover plate 5, and the adjustment component can adjust the working state of the ventilator in different weather conditions;

[0035] The adjustment component includes a bidirectional motor 6, and the output ends on both sides of the bidirectional motor 6 are fixedly connected to a transmission shaft 601, one end of the transmission shaft 601 is fixedly connected to a gear 1 602, the upper part of the gear 1 602 is meshed with a gear 2 603, and the surface of the gear 2 603 is also meshed with two groups of arc-shaped racks 604, and the surface of the arc-shaped racks 604 is fixedly connected to a telescopic connecting plate 605, one side of the telescopic connecting plate 605 is fixedly connected to the movable plate 3, the arc-shaped rack 604 slides inside the bracket 2, and the gear 2 603 is rotatably connected to the bracket 2.

[0036] The present invention takes into account that, in order to improve the ventilation effect of the factory building, the existing natural ventilator is generally installed at the skylight position of the factory building when in use, and the air in the factory building is cooled down by natural wind. However, when encountering weather changes with continuous rainfall, the interaction between rainwater and airflow may destroy the anti-seepage ability of the ventilation structure, causing rainwater backflow, which will not only reduce the ventilation effect of the factory building, but also the backflow of rainwater may easily cause damage to the equipment in the factory building. Therefore, the two sets of gears 1 602 are driven to rotate by the rotation of the bidirectional motor 6, and the gear 1 602 is meshed with the transmission to drive the gear 2 603 to rotate, and the gear 2 60 The rotational meshing transmission drives the two sets of arc-shaped racks 604 to move relative to each other on the inner side of the bracket 2. At this time, the arc-shaped racks 604 can drive the two sets of movable plates 3 to move inward inside the housing 1 through the telescopic connecting plate 605. Since the thickness of the middle position of the two sets of movable plates 3 is different, one side of one set of movable plates 3 can be inserted into the inside of the other set of movable plates 3 to block the front and rear sides of the ventilator, so that the ventilator is in a semi-sealed state, which can not only isolate rainwater and prevent the phenomenon of rainwater backflow, but also make the adjusted ventilator in a semi-sealed state, so that the factory building can continue to be ventilated;

[0037] It should be noted that when the ventilator is in a semi-sealed state, due to the different thicknesses of the two groups of movable plates 3, when one side of one group of movable plates 3 is inserted into the interior of the other group of movable plates 3, the junction of the two groups of movable plates 3 is in a "sealed state", which can effectively isolate rainwater, and because the two groups of arc-shaped racks 604 slide inside the bracket 2, and the bracket 2 is arranged in an arc shape, when the arc-shaped rack 604 drives the movable plate 3 to move through the telescopic connecting plate 605, the telescopic connecting plate 605 will perform a telescopic movement, which can ensure that the movable plate 3 is stable during the movement process, and avoid that one side of one group of movable plates 3 cannot be accurately inserted into the interior of the other group of movable plates 3;

[0038] It should be noted again that when the ventilator is in a semi-sealed state as a whole, rainwater will fall from the upper and lower parts of the housing 1 to the surface of the cover plate 5 installed inside the housing 1. Since the cover plate 5 is also arranged in an arc shape, the rainwater will be directed to the two sides of the housing 1 after contacting the surface of the cover plate 5. However, since ventilation holes are provided on the left and right sides of the housing 1, when the rainwater slides from the surface of the cover plate 5, it will be discharged from the position of the ventilation holes, and the rainwater will not enter the bottom of the base 4 to cause the rainwater to flow back, and the rainwater can be isolated;

[0039] It should be further explained that when the ventilator is used in clear weather, the bidirectional motor 6 is started to drive the transmission shaft 601 to rotate in the reverse direction, and the transmission shaft 601 drives gear 1 602 to reverse, and the reverse meshing transmission of gear 1 602 drives gear 2 603 to reverse. Therefore, the arc-shaped rack 604 will drive the movable plate 3 to move outward through the telescopic connecting plate 605 when gear 2 603 rotates in the reverse direction, until the movable plate 3 moves to a suitable position inside the shell 1. At this time, the ventilator as a whole is in an open state. At this time, when the outside air flows, it can better flow into the factory building through the ventilator to ventilate the factory building.

[0040] like Figures 6 to 8 As shown, a drainage groove 10 is provided at the connection position between the shell 1 and the base 4 , the lower half of the drainage groove 10 is arc-shaped and provided inside the base 4 , and the drainage groove 10 is located below the ventilation holes provided on both sides of the shell 1 .

[0041] The present invention also takes into account that when rainwater slides down the surface of the cover plate 5 and is discharged from the ventilation holes opened on both sides of the shell 1, part of the rainwater may adhere to the surface of the cover plate 5 and drip in the form of water drops. At this time, the rainwater will not be discharged directly from the ventilation holes, but will drip onto the top of the base 4, and then slide into the inside of the base 4, resulting in backflow. Therefore, by opening a drainage groove 10 at the position where the shell 1 and the base 4 are connected, when rainwater slides down through the surface of the cover plate 5, part of the rainwater will be discharged from the ventilation hole position, and another part of the rainwater will fall into the inside of the drainage groove 10. Moreover, since a part of the drainage groove 10 is opened inside the base 4 and is arranged in an arc shape, when rainwater drips, it will contact the arc surface. At this time, the rainwater will slide out from the arc surface inside the drainage groove 10 with "acceleration", which can avoid the accumulation of rainwater inside the drainage groove 10 after dripping, and can quickly guide the rainwater to be discharged to the outside of the ventilator.

[0042] It should be further explained that when the ventilator is used in clear weather, the two sets of movable plates 3 slide from the inside of the outer shell 1 to the outside. At this time, the front and back of the ventilator are in a "through" state. At the same time, the ventilation holes on both sides of the outer shell 1 can also allow outside air to enter the interior of the factory, and air can also enter from the top of the outer shell 1, which can make the ventilator in a "fully open" state, allowing outside air to enter the interior of the factory from all angles, and can fully ventilate the interior of the factory, with a good ventilation effect.

[0043] like Figures 9 and 10 As shown, the inside of the base 4 is fixedly connected to an electric motor 8, the output end of the electric motor 8 is fixedly connected to a rotating rod 801, the surface of the rotating rod 801 is fixedly connected to an upper guide plate 802 and a lower guide plate 803, the electric motor 8 drives the upper guide plate 802 and the lower guide plate 803 to adjust the angle through the rotating rod 801, and the rotating rod 801 and the base 4 are rotatably connected.

[0044] The present invention also fully considers that when the ventilator is used in weather with continuous rainfall, the ventilator is in a semi-sealed state. At this time, the outside air can only enter the interior of the factory from the ventilation holes opened on both sides of the shell 1 and the top of the shell 1. At this time, the ventilation effect will be reduced, and because the ventilator is in a semi-sealed state, the efficiency of exhausting air inside the factory is also low, and it is impossible to effectively achieve fast and effective ventilation inside the factory. Therefore, when the two sets of movable plates 3 are tightly fitted, the electric motor 8 will rotate to drive the rotating rod 801 to rotate, and the rotation of the rotating rod 801 drives the upper guide plate 802 and the lower guide plate 803 to adjust the angle until the gap between the two sets of upper guide plates 802 is the same as the gap size of the lower guide plate 803 close to the base 4, so that the upper guide plate 802 and the lower guide plate 803 are in a "vertical" state with the base 4, and because the upper guide plate 802 The upper and lower guide plates 803 are both arranged in an arc shape. When the two groups of upper guide plates 802 are close to each other, after the outside air enters through the top of the shell 1, it will first contact the surface of the upper guide plate 802, and then be guided to the inside of the base 4 by the arc surface of the lower guide plate 803. When the air enters the factory from the gap between the two groups of upper guide plates 802, due to the rainfall, the air temperature outside the factory is generally lower than the air temperature inside the factory. At this time, the outside air will "squeeze" the internal air to make it move to both sides. At this time, the air will be discharged from the gap between the inner arc surface of the lower guide plate 803 and the base 4. In addition, since the gap between the two groups of upper guide plates 802 is the same size as the gap on the side of the lower guide plate 803 close to the base 4, the speed and volume of the outside air entering are the same as the speed and volume of the internal air discharged, so that the interior of the factory can be ventilated quickly.

[0045] It should be noted that, since ventilation holes are provided on both sides of the shell 1, when the ventilator is in a semi-sealed state, outside air will also blow into the interior of the ventilator from the position of the ventilation holes. However, since the upper guide plate 802 is in an adjusted state at this time, one end of the upper guide plate 802 will be located below the ventilation hole. Therefore, when the air blows into the interior of the ventilator from the ventilation hole, the air will be "diverted" by the upper guide plate 802 when it contacts the upper guide plate 802. Part of the air will still be guided to the interior of the factory from the curved surface of the upper guide plate 802, while the air inside the factory will continue to be discharged from the gap between the lower guide plate 803 and the base 4, and the air inside the factory will always be in a state of being "squeezed" by the outside air. Therefore, at this time, another part of the air diverted by the upper guide plate 802 will contact with the discharged air and be carried away by the discharged gas. In addition, the curved surface of the upper guide plate 802 can continue to divert the air entering from the ventilation hole, so that the air can still be guided to the interior of the factory from the curved surface of the upper guide plate 802 to cool the interior of the factory.

[0046] It should be further explained that when the ventilator is used in clear weather, since the ventilator is in the "fully open" state at this time, the electric motor 8 will not drive the rotating rod 801 to drive the upper guide plate 802 and the lower guide plate 803 to adjust the angle. Therefore, the arc surfaces of the two sets of upper guide plates 802 are in a state of being separated. At this time, when the outside air enters the ventilator through various positions, it will be fully guided into the interior of the factory by the arc surfaces of the upper guide plates 802. At this time, the two sets of upper guide plates 802 are in a state of being separated, and the gap between the two sets of lower guide plates 803 and the base 4 is large. Therefore, the amount of air entering is roughly the same as the amount of air discharged, which can avoid the amount of air entering being greater than the amount of air discharged. The incoming air will block the discharged air, reducing the efficiency of ventilation in the factory.

[0047] It needs to be explained that when the two groups of upper guide plates 802 are in a state of being far away, the gap between the inner arc surface of the two groups of lower guide plates 803 and the base 4 is relatively large. At this time, after the outside air is fully guided by the upper guide plates 802, since the outer arc surfaces of the two groups of lower guide plates 803 are in a state of being close, the outside air is in a "concentrated" state after entering the factory building, which can fully "squeeze" the internal air so that the internal air can be quickly discharged from the gap between the inner arc surface of the lower guide plate 803 and the base 4. Therefore, the amount of air discharged at this time will become larger, and the situation where the outer arc surface of the lower guide plate 803 is close and affects the outside air from quickly entering the interior of the factory building, thereby reducing the amount of air entering. The ventilation volume of the factory building can always be kept in a "balanced" state, and the internal ventilation of the factory building can be effectively treated.

[0048] like Figure 2 , Figure 6 and Fig.11 As shown, the positions of the ventilation holes on both sides of the shell 1 are rotatably connected with an adjustment plate 9 through a pin shaft, one side of the adjustment plate 9 is fixedly connected with a sliding rod 902, the surface of the sliding rod 902 is slidably connected with a sleeve 903, and one end of the sleeve 903 is fixedly connected to the base 4.

[0049] During operation, when the ventilator is in a semi-sealed state, outside air will enter the interior of the ventilator from the ventilating holes and the position above the shell 1. However, when rain falls on the outside of the ventilator, some of the rain will splash and enter the interior of the ventilator from the position of the ventilating holes, thereby improving the effect of the drainage groove 10 on rainwater discharge. Therefore, by installing an adjustment plate 9 at the position of the ventilating hole, when rain falls from the surface of the cover plate 5, it will be limited by the inner surface of the adjustment plate 9, thereby sliding down from the inner surface of the adjustment plate 9. Moreover, the adjustment plate 9 is arranged at an angle at the position of the ventilating hole, thereby preventing rainwater from splashing and entering the interior of the ventilator from the ventilating hole.

[0050] It should be noted that when the ventilator is in a semi-sealed state, when air enters from the position of the ventilation hole, due to the effect of the adjustment plate 9, the outside air will enter from the gap between the adjustment plate 9 and the base 4, and flow in a "from bottom to top" direction. Therefore, after the outside air enters, it will first contact the end surface of the upper guide plate 802, and then be diverted by the upper guide plate 802, so that the upper guide plate 802 can better guide the air;

[0051] It should be further explained that, since the adjustment plate 9 is tilted at a certain angle at this time, and the height of the drainage groove 10 is lower than the height of the bottom surface of the tilted adjustment plate 9, when the outside air enters the interior of the ventilator through the gap between the adjustment plate 9 and the base 4, the outside air will not blow into the interior of the drainage groove 10, which can prevent the air from blowing into the interior of the drainage groove 10 and exerting a blowing force on the rainwater being discharged, causing it to flow back, thereby improving the drainage effect of the drainage groove 10.

[0052] like Fig.11 As shown, an active rod 901 is fixedly connected to the middle position of the adjustment plate 9, and the length of the sliding rod 902 inside the sleeve 903 is fixed. The two ends of the active rod 901 are slidingly connected to the opened moving plate 3. An inclined groove 301 is provided on the inner side of the moving plate 3, and the inclined groove 301 is inclined at a certain angle. The moving plate 3 drives the adjustment plate 9 on the surface of the active rod 901 to swing through the inclined groove 301, and the active rod 901 drives the sliding rod 902 to slide inside the sleeve 903.

[0053] During operation, when the ventilator is used in clear weather, the movable plate 3 will move to both sides inside the housing 1. Since the inner surface of the movable plate 3 is provided with an inclined groove 301, when the movable plate 3 moves, it will drive the active rod 901 to move upward. Since the active rod 901 is fixed to the adjustment plate 9, the adjustment plate 9 and the housing 1 rotate through the pin shaft, the active rod 901 will drive the adjustment plate 9 to swing around the pin shaft after being subjected to force. When the movable plate 3 reaches the specified position, the adjustment plate 9 stops rotating and is in a fully open state. At this time, it is more convenient for the outside air to enter the inside of the ventilator from the ventilation hole position, and the adjustment plate 9 can be prevented from blocking the outside air.

[0054] It should be noted that when the ventilator is used in continuous rainy weather, the movable plate 3 will move inward inside the housing 1. When the movable plate 3 is moving, the two ends of the active rod 901 will gradually disengage from the inclined slot 301. At this time, the adjusting plate 9 will be reset under the action of gravity and external air, and because the length of the sliding rod 902 inside the sleeve 903 is fixed, even after the adjusting plate 9 is reset, the sliding rod 902 is fully inserted into the sleeve 903, and the sliding rod 902 will still support the adjusting plate 9, so that the ventilation hole can always be in an open state, and the sliding rod 902 can always be in a state of being fully inserted into the sleeve 903, so that when the movable plate 3 is opened again, the inclined slot 301 can again accurately cooperate with the active rod 901, so that the adjusting plate 9 can be flipped at a certain angle;

[0055] It should be further explained that when the adjustment plate 9 is in the open state, the gap between the adjustment plate 9 and the base 4 will become larger, so the outside air can enter the interior of the ventilator more smoothly, and the adjustment plate 9 is in the open state, and the height of its bottom surface is higher than the lowest position of the ventilation hole. Therefore, the outside air can flow to the interior of the ventilator in a parallel state, and no longer flows in a "bottom-to-top" state, which can make the air entering the ventilation hole smoother and can effectively improve the effect of the upper guide plate 802 on air diversion.

[0056] like Figures 3 to 5 As shown, a protective shell 7 is fixedly connected to the surface of the bidirectional motor 6, and the protective shell 7 is made of waterproof material. The protective shell 7 is fixedly connected to the base 4, and the diameter of gear 1 602 is greater than the diameter of gear 2 603.

[0057] During operation, the bidirectional motor 6 is first installed inside the protective shell 7. When encountering continuous rainy weather, the bidirectional motor 6 is inside the protective shell 7 during operation. The protective shell 7 is made of waterproof material, which can effectively prevent the bidirectional motor 6 from being eroded by rain and caused damage. It should be noted that when the bidirectional motor 6 drives gear 1 602 to rotate through the transmission shaft 601, since the diameter of gear 1 602 is greater than the diameter of gear 2 603, when gear 1 602 rotates, it can drive gear 1 602 to rotate quickly, so that the two groups of arc-shaped racks 604 meshing on the surface of gear 2 603 can quickly drive the moving plate 3 to slide inside the outer shell 1 through the telescopic connecting plate 605, so that the ventilator can be in a semi-sealed state before it rains, and the use state of the ventilator in different environments can be quickly changed, and the working efficiency is high.

[0058] like Fig. 9As shown, the electric motor 8 is fixedly connected to the base 4, the surface of the electric motor 8 is covered with waterproof material, the upper guide plate 802 and the lower guide plate 803 swing around the axis of the rotating rod 801, and the upper guide plate 802 and the lower guide plate 803 are both arranged directly below the cover plate 5.

[0059] When working, by arranging waterproof material on the surface of the electric motor 8, it is possible to prevent rain from eroding and damaging the electric motor 8, and when the electric motor 8 drives the upper guide plate 802 and the lower guide plate 803 to adjust the angle through the rotating rod 801, the upper guide plate 802 and the lower guide plate 803 will swing around the axis of the rotating rod 801, so that the two groups of upper guide plates 802 and lower guide plates 803 can move in opposite or opposite directions, and the inclination angle of the upper guide plate 802 and the lower guide plate 803 can be accurately controlled. It should be noted that the upper guide plate 802 and the lower guide plate 803 are arranged just below the cover plate 5. The plate 5 is fixedly connected to the bracket 2. After the upper guide plate 802 and the lower guide plate 803 are adjusted in angle, both of them can be always located below the cover plate 5, which can prevent rainwater sliding down from the surface of the cover plate 5 from dripping onto the surface of the upper guide plate 802, and prevent rainwater from being brought into the interior of the factory by the outside air. The rainwater can be effectively isolated, and when the two groups of upper guide plates 802 move toward each other, at this time, since the edge of the cover plate 5 is always located above the base 4, and the edge of the upper guide plate 802 is always located on the inner side below the cover plate 5, rainwater will not directly fall onto the upper surface of the upper guide plate 802, affecting the ventilation effect.

[0060] like Figures 9 and 10 As shown, the connection between the lower guide plate 803 and the rotating rod 801 is arranged horizontally, and a through groove is provided at the connection position between the upper part of the lower guide plate 803 and the rotating rod 801, and the through groove is connected to the outside of the ventilator.

[0061] During operation, as outside air enters the interior of the ventilator through the position of the ventilation hole, rainwater dripping on the surface of the cover plate 5 is blown by the air and may be blown to the upper surface of the upper guide plate 802. However, since the upper guide plate 802 and the lower guide plate 803 are in a "vertical" state with the base 4 at this time, part of the rainwater will flow along the outer arc surface of the upper guide plate 802 to the surface of the rotating rod 801, and then flow from the surface of the rotating rod 801 into the through groove opened at the connection position between the lower guide plate 803 and the rotating rod 801, and then be discharged from the inside of the through groove to the interior of the ventilator. It should be noted that since the surface of the electric motor 8 is covered with waterproof material, even if part of the rainwater contacts the surface of the electric motor 8, it will not cause damage to it, and the through groove is connected to the outside of the ventilator. When the lower guide plate 803 and the base 4 are in a "vertical" state, the through groove is also in an inclined state, which makes it more convenient for rainwater to be discharged from the inside of the through groove, and can effectively improve the effect of isolating rainwater and prevent rainwater from entering the interior of the factory through the ventilator.

[0062] like Figure 1 to Figure 2 As shown, the bracket 2 and the cover plate 5 are connected to the bracket 2 by stainless steel self-tapping screws. The bracket 2 is made of glass fiber reinforced plastic square tube as a whole, and the connecting parts are all made of stainless steel. The base 4 is fixedly connected to the steel beam of the factory roof through stainless steel parts.

[0063] The present invention also fully considers that when traditional ventilators deal with continuous heat source release and highly corrosive chemical media such as acidic aerosols and alkaline steam emissions, the gases generated by the media will corrode the equipment, damage the structure, and shorten the service life. Therefore, by making the bracket 2 as a whole out of fiberglass, and the outer shell 1 and cover plate 5 connected to the bracket 2 are connected to it with stainless steel nails, the damage caused to the ventilator by highly corrosive gases can be effectively reduced, the service life of the entire ventilator equipment can be increased, and the cost of use can be reduced. The base 4 is fixedly connected to the factory roof through stainless steel parts, which can avoid long-term impact due to strong winds or rain, reduce the stability of the ventilator, and can effectively improve the stability of the ventilator when in use.

[0064] like Figure 1 to Figure 2 as well as Figure 6 As shown, the movable plate 3, the upper guide plate 802, the lower guide plate 803 and the adjustment plate 9 are all made of stainless steel material, the upper guide plate 802 and the lower guide plate 803 are both arranged inside the base 4, and the lower end length of the lower guide plate 803 does not exceed the position where the base 4 is connected to the factory roof steel beam.

[0065] During operation, by making the movable plate 3, the upper guide plate 802, the lower guide plate 803 and the adjustment plate 9 of stainless steel, when highly corrosive gases are discharged, they can be prevented from being damaged during use, which can effectively improve the service life of the overall ventilator equipment and reduce the cost of use.
