Description

Technical Field

[0001] The utility model relates to the technical field of ridge ventilation, in particular to a parallel sliding ridge ventilator. Background Art

[0002] At present, most industrial plants, warehouses and other buildings are made of steel frame structures. For the needs of ventilation and heat dissipation, ventilation structures are usually installed on the roofs of the buildings.

[0003] For example, the prior art (authorization announcement number: CN207003770U) discloses a factory roof ventilation structure, as shown in the attached Figure 1 As shown, it includes a main beam frame and a top plate 1, the main beam frame is a frame structure formed by connecting a plurality of main beams 2 and a plurality of main beam rods 20, the main beams 2 are arranged in parallel and spaced in sequence and transversely, the main beam rods 20 are arranged in parallel and spaced in sequence and longitudinally, and the top plate 1 is laid on the main beam frame; an upper beam frame is arranged above the main beam frame, the upper beam frame is a frame structure formed by connecting a plurality of upper beams 3 and a plurality of upper beam rods 30, the upper beams 3 are arranged in parallel and spaced in sequence and transversely, the upper beam rods 30 are arranged in parallel and spaced in sequence and longitudinally, the upper beams 3 are arranged one by one with the main beams 2, and are connected by two vertically arranged vertical rods 4; a top plate air outlet is provided in the middle of the top plate 1, and vertically arranged rainproof vertical plates 12 are provided near the four sides of the top plate air outlet.

[0004] However, the above-mentioned prior art still has the following problems in actual use: when the ventilation demand is small or there is no ventilation demand, since the top plate air outlet cannot be adjusted in size or directly closed, the heating or cooling demand of the factory will increase in the low temperature in winter or the high temperature in summer, thereby causing energy waste in the factory.

[0005] Therefore, it is now urgently necessary to install parallel sliding ridge ventilators at the air outlet to adjust the size of the air outlet or directly close the air outlet to meet the ventilation needs in various production environments and reduce energy waste in the factory. Utility Model Content

[0006] The utility model aims to provide a parallel sliding ridge ventilator to solve the technical problem that the top plate air outlet of the prior art cannot be adjusted in size or can be directly closed, resulting in energy waste in the factory.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A parallel sliding ridge ventilator comprises at least one ventilation assembly arranged along the length direction of the air outlet, the ventilation assembly comprises a driving part and a ventilation part; the driving part comprises a driving motor, a driving sprocket, a driven sprocket and a driving chain, the driving sprocket is arranged at the output end of the driving motor, and the driving chain is tensioned and engaged with the driving sprocket and the driven sprocket; the ventilation part comprises an upper wind plate and a lower wind plate arranged in parallel, both the upper wind plate and the lower wind plate are connected to the driving chain, the driving chain drives the upper wind plate and the lower wind plate to approach or move away from each other along the width direction of the air outlet, and the sum of the widths of the upper wind plate and the lower wind plate matches the width of the air outlet.

[0009] The principle and beneficial effects of this program:

[0010] In actual application, the driving motor of the driving unit is started, and the driving motor drives the driving sprocket to rotate, and the driving sprocket drives the driving chain to move, thereby driving the upper plate and the lower plate of the ventilation unit to approach each other along the width direction of the air outlet, so that the upper plate and the lower plate overlap each other and no longer completely close the air outlet, thereby realizing open ventilation of the air outlet. When the ventilation demand is small or there is no ventilation demand, the driving motor of the driving unit is started, and the driving motor drives the driving sprocket to rotate in the opposite direction, and the driving sprocket drives the driving chain to move in the opposite direction, thereby driving the upper plate and the lower plate of the ventilation unit to move away from each other along the width direction of the air outlet, so that the overlapping area of ​​the upper plate and the lower plate becomes smaller or no longer overlaps, thereby realizing a reduced ventilation area or complete closure of the air outlet.

[0011] Therefore, this solution can flexibly adjust the ventilation area of ​​the air outlet according to the actual ventilation needs of production. It can effectively reduce the heating or cooling needs of the factory building when the temperature is low in winter or high in summer, thereby reducing or even avoiding energy waste in the factory building, which is conducive to reducing production costs.

[0012] In addition, this solution sets the sum of the widths of the upper and lower wind plates to match the width of the air outlet. When there is no ventilation demand in the factory building, the driving unit drives the upper and lower wind plates to move away from each other until the upper and lower wind plates can completely block the air outlet. At this time, the upper and lower wind plates no longer overlap, that is, there is no margin between the upper and lower wind plates along the width direction of the air outlet. Then, when the driving unit drives the upper risk and lower closure to move closer to each other to open the air outlet, the ventilation area of ​​the air outlet can be maximized to meet the large ventilation demand of the factory building.

[0013] Preferably, as an improvement, the upwind plate is a transparent upwind plate, and the downwind plate is a transparent downwind plate.

[0014] Beneficial effect: This solution adopts transparent upwind plates and transparent downwind plates. Even if the upwind plates and downwind plates close the air outlets, light can be collected through the upwind plates and downwind plates to increase the brightness in the factory, thereby reducing the number of lights turned on in the factory, which is conducive to reducing energy consumption in the factory.

[0015] Preferably, as an improvement, the ventilation part also includes a plurality of upper rails and lower rails arranged along the width direction of the air outlet, and upper pulleys and lower pulleys are respectively provided at the bottom of the upper wind plate and the lower wind plate, and the upper pulleys and the lower pulleys are respectively slidably connected in the upper rails and the lower rails.

[0016] Beneficial effects: In this solution, a plurality of upper and lower tracks are arranged along the width direction of the air outlet, and the upper pulley and the lower pulley are respectively slidably connected to the upper and lower tracks. When the driving chain of the driving unit drives the upper and lower air plates to approach or move away from each other along the width direction of the air outlet, the upper pulley and the lower pulley respectively slide with the upper and lower tracks, and guide and limit the moving direction of the upper and lower air plates, thereby ensuring the accurate opening or closing of the air outlet and the accurate adjustment of the ventilation area. In addition, the upper and lower tracks can also play a good supporting role for the upper and lower air plates, preventing the upper and lower air plates from falling off the driving chain, and ensuring production safety in the factory.

[0017] Preferably, as an improvement, the driving portion further comprises a supporting sprocket located between the driving sprocket and the driven sprocket, and the driving chain is meshed with the supporting sprocket.

[0018] Beneficial effects: This solution adds a support sprocket between the driving sprocket and the driven sprocket, and makes the driving chain mesh with the support sprocket. The middle part of the driving chain can be supported by the support sprocket, reducing or even avoiding the sagging of the middle part of the driving chain due to gravity, improving the tensioning effect of the driving chain, ensuring the transmission accuracy and efficiency of the driving chain, thereby ensuring the position accuracy of the driving chain when driving the upper and lower wind plates to move closer or farther from each other, so as to accurately meet various ventilation needs in actual production. At the same time, the tensioned driving chain can reduce or even avoid shaking and slapping during operation, thereby reducing the friction between the driving chain and the driving sprocket, the driven sprocket, and the support sprocket, while reducing the wear of the driving chain itself, which is conducive to extending the service life of the entire driving unit.

[0019] Preferably, as an improvement, the driving unit further comprises a chain tensioning device, and the chain tensioning device is used for tensioning the driving chain.

[0020] Beneficial effects: This solution additionally sets a chain tensioning device for tensioning the drive sprocket, which can further improve the tensioning effect of the drive chain, thereby further improving the transmission accuracy and efficiency of the drive chain, while reducing the friction between the drive chain and the active sprocket, driven sprocket, and support sprocket, and reducing the wear of the drive chain itself, thereby extending the service life of the entire drive unit. In addition, when the length of the drive chain does not match the width of the air outlet, the effective working length of the drive chain can be adjusted by the chain tensioning device so that the effective working length of the drive chain matches the width of the air outlet, so as to ensure that when the drive chain drives the upper air plate and the lower air plate to move closer to or away from each other, the air outlet can be effectively opened or closed to meet different ventilation requirements in the actual production process.

[0021] Preferably, as an improvement, both the upper wind plate and the lower wind plate are provided with a fixing rod, and the other end of the fixing rod is connected to the driving chain.

[0022] Beneficial effects: In this solution, fixed rods are set on the upwind plate and the downwind plate, which are connected to the drive chain through the fixed rods. The structure is simple and will not excessively increase the load of the drive chain, which is beneficial to reducing energy consumption and ensuring the service life of the drive unit.

The specific number of ventilation components is determined according to the length of the air outlet to ensure that the air outlet is fully covered. In this embodiment, the number of ventilation components is one.

[0029] As attached Figure 2As shown, the ventilation assembly includes a driving part and a ventilation part, the driving part includes a driving motor 51, a driving sprocket 52, a driven sprocket 53, a supporting sprocket 54 and a driving chain 55, the driving motor 51 is fixedly connected to the main beam frame by bolts, the supporting sprocket 54 is located between the driving sprocket 52 and the driven sprocket 53, the axes of the driving sprocket 52, the driven sprocket 53 and the supporting sprocket 54 are parallel to each other, and the driving sprocket 52, the driven sprocket 53 and the supporting sprocket 54 are all rotatably connected to the main beam frame, and the driving chain 55 is tensioned and meshed with the driving sprocket 52, the driven sprocket 53 and the supporting sprocket 54 along the width direction of the air outlet. The driving sprocket 52 is arranged at the output end of the driving motor 51. In this embodiment, the driving sprocket 52 is transmission-connected to the output end of the driving motor 51 through a worm gear. Specifically, the output end of the driving motor 51 is coaxially fixedly connected with a worm gear, and the driving sprocket 52 is coaxially fixedly connected with a worm gear, and the worm gear meshes with the worm gear.

[0030] In this embodiment, the driving motor 51 is a stepper motor or a servo motor, which can not only realize forward and reverse rotation, but also perform precise position control and speed control to ensure that the ventilation area of ​​the air outlet meets production requirements.

[0031] The ventilation part includes an upper wind plate 61 and a lower wind plate 62 which are arranged parallel to each other. The upper wind plate 61 is a transparent upper wind plate 61, and the lower wind plate 62 is a transparent lower wind plate 62. In this embodiment, the upper wind plate 61 and the lower wind plate 62 are both arranged horizontally. The upper wind plate 61 and the lower wind plate 62 are both connected to the driving chain 55, and the driving chain 55 drives the upper wind plate 61 and the lower wind plate 62 to approach or move away from each other along the width direction of the air outlet; specifically, one end of the upper wind plate 61 is fixedly connected to an upper fixed rod 63, the top end of the upper fixed rod 63 is fixedly connected to the driving chain 55, and the connection between the upper fixed rod 63 and the driving chain 55 is located above the axis of the driving sprocket 52, and one end of the lower wind plate 62 is fixedly connected to a lower fixed rod 64, the top end of the lower fixed rod 64 is fixedly connected to the driving chain 55, and the connection between the lower fixed rod 64 and the driving chain 55 is located below the axis of the driving sprocket 52. The sum of the widths of the upper wind plate 61 and the lower wind plate 62 matches the width of the air outlet, that is, the sum of the widths of the upper wind plate 61 and the lower wind plate 62 is equal to the width of the air outlet. In this embodiment, the widths of the upper wind plate 61 and the lower wind plate 62 are both half of the width of the air outlet, and the lengths of the upper wind plate 61 and the lower wind plate 62 are equal to the length of the outlet air.

[0032] The ventilation part also includes a plurality of upper rails 65 and a plurality of lower rails 66 arranged along the width direction of the air outlet. The plurality of upper rails 65 and the plurality of lower rails 66 are evenly arranged along the length direction of the air outlet, and the plurality of upper rails 65 and the plurality of lower rails 66 are arranged one to one. Both ends of the upper rails 65 and the lower rails 66 are fixedly connected to the main beam frame, and can be specifically fixed by welding or bolts. The upper wind plate 61 is rotatably connected to a plurality of upper pulleys 67 corresponding to the position of the upper rail 65, and the upper pulleys 67 are slidably connected to the upper rail 65; the lower wind plate 62 is rotatably connected to a plurality of lower pulleys 68 corresponding to the position of the lower rail 66, and the lower pulleys 68 are slidably connected to the lower rail 66.

[0033] The specific implementation process is as follows:

[0034] Open the air outlet: When the ventilation demand of the factory production is large, start the driving motor 51 of the driving unit, the driving motor 51 drives the driving sprocket 52 to rotate, and the driving sprocket 52 drives the driving chain 55 to rotate, thereby driving the upper plate 61 and the lower plate 62 of the ventilation unit to approach each other along the width direction of the air outlet. At this time, the upper pulley 67 and the lower pulley 68 slide in the upper slide rail and the lower slide rail respectively, which not only guide and limit the movement direction of the upper plate 61 and the lower plate 62, but also support the upper plate 61 and the lower plate 62. Until the upper plate 61 and the lower plate 62 are completely overlapped, turn off the driving motor 51, and the air outlet is opened, and the ventilation area of ​​the air outlet reaches the maximum.

[0035] Adjust the ventilation area of ​​the air outlet: when the ventilation demand of the factory production is small, start the drive motor 51 of the drive unit, the drive motor 51 drives the active sprocket 52 to rotate in the opposite direction, and the active sprocket 52 drives the drive chain 55 to rotate in the opposite direction, thereby driving the upper air plate 61 and the lower air plate 62 of the ventilation unit to move away from each other along the width direction of the air outlet, so that the overlapping area of ​​the upper air plate 61 and the lower air plate 62 becomes smaller, and turn off the drive motor 51. At this time, the ventilation area of ​​the air outlet is reduced.

[0036] Close the air outlet: When there is no ventilation demand in the factory production, start the drive motor 51 of the drive unit, and the drive motor 51 drives the active sprocket 52 to continue to rotate in the reverse direction. The active sprocket 52 drives the drive chain 55 to rotate in the reverse direction, thereby driving the upper air plate 61 and the lower air plate 62 of the ventilation unit to continue to move away from each other along the width direction of the air outlet until the upper air plate 61 and the lower air plate 62 no longer overlap, and turn off the drive motor 51. At this time, the air outlet is completely blocked by the upper air plate 61 and the lower air plate 62, and the air outlet is closed.

[0037] Example 2

[0038] The parallel sliding ridge ventilator is different from the embodiment 1 in that the driving part further includes a chain tensioning device, which is used to tension the driving chain 55. The chain tensioning device adopts the chain tensioner in the prior art, and its structure is not described in detail in this embodiment.

[0039] This solution additionally sets a chain tensioning device for tensioning the driving sprocket, which can improve the tensioning effect of the driving chain 55, thereby improving the transmission accuracy and efficiency of the driving chain 55, while reducing the friction between the driving chain 55 and the driving sprocket 52, the driven sprocket 53, and the supporting sprocket 54, and reducing the wear of the driving chain 55 itself, thereby extending the service life of the entire driving unit. In addition, when the length of the driving chain 55 does not match the width of the air outlet, the effective working length of the driving chain 55 can be adjusted by the chain tensioning device so that the effective working length of the driving chain 55 matches the width of the air outlet, so as to ensure that when the driving chain 55 drives the upper air plate 61 and the lower air plate 62 to move closer to or away from each other, the air outlet can be effectively opened or closed to meet different ventilation requirements in the actual production process.

It should be pointed out that for those skilled in the art, without departing from the technical solution of the utility model, several deformations and improvements can be made, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent.
