Description

Technical Field

[0001] The invention relates to the technical field of industrial skylights, in particular to an industrial electric lighting, ventilation and smoke exhaust skylight. Background Art

[0002] Ventilation and smoke exhaust skylights are mostly open skylights without window sashes, and only have rain shields to prevent rain from drifting into the room. Opening sashes can also be set, but they are not tightly closed. They are suitable for factories with high indoor temperatures, large exhaust volumes, and high ventilation requirements.

[0003] Now most factories use electric skylights for lighting and smoke exhaust. The basic principle is to drive the skylight switch through an electric push rod, which is convenient for practical use. For example, the publication number is CN104047400B, which discloses an electric skylight for lighting and smoke exhaust, including a truss structure, with wind shields and flashing plates around the truss structure, upper, middle and lower rain shields evenly distributed on the truss structure, a splashproof net is provided between the upper and lower rain shields on the truss structure, and a wind shield valve plate connected to each other by a connecting rod is hinged on the truss structure; an electric drive device connected to the wind shield valve plate is also provided on the truss structure, and the wind shield valve plate automatically opens and is in a vertical state after the electric drive device is powered off. The advantages are: it has both building lighting and ventilation and fire smoke exhaust functions, which can ensure the daily energy-saving ventilation adjustment needs of the building and the large-scale ventilation needs of fire emergencies; the wind shield valve plate can be automatically opened in case of power failure, and the ventilation and smoke exhaust channel can be quickly opened within 1 second, which can ensure the rapid opening of the smoke exhaust function required by fire protection, and provide more opportunities for people to escape when a fire occurs in the building.

[0004] However, both this patent and the prior art will cause the window to face upward or diagonally upward when the skylight is opened, and the surface of sealing components such as sealing strips provided on the window are easily contaminated with impurities and dust. At the same time, because the switch of the skylight is controlled by an electric push rod, most staff will not actively observe and remove the impurities and dust on the surface of sealing components such as sealing strips when closing it. In addition, the height of the skylight is usually high and cannot be directly observed. When harder impurities and dust fall on the sealing strip, they will be squeezed and worn when the window is closed, resulting in faster wear of the sealing strip. At the same time, when rod-shaped objects such as leaves fall on the sealing strip, they will be inserted in a tightly closed place due to the closure of the window. In this way, when the leaves and other rod-shaped objects are drenched by rain, water will be introduced into the inside of the window, and then fall into the room, causing dripping in the factory area. Summary of the invention

[0005] The object of the present invention is to provide an industrial electric lighting, ventilation and smoke exhaust skylight to solve the problem proposed in the above-mentioned background technology that impurities and dust on the surface of sealing components such as sealing strips set on the window will be squeezed and worn by the sealing strips when the window is closed, thereby causing the sealing strips to wear out faster. At the same time, when rod-shaped objects such as leaves fall on the sealing strips, they will be inserted in a tightly closed place due to the closure of the window. In this way, when rod-shaped objects such as leaves are drenched by rain, water will be introduced into the inside of the window, and then fall into the room, causing dripping in the factory area.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figure 1-11 , an embodiment of the present invention: an industrial electric lighting, ventilation and smoke exhaust skylight, comprising a window frame 1, a window sash 2 is installed on the upper end of the window frame 1 through a hinge, an electric push rod 3 is arranged between the window sash 2 and the window frame 1, a sealing convex strip 11 is arranged on the upper end of the window frame 1, a sealing rubber pad 12 is glued to the upper end of the sealing convex strip 11, locking blocks 6 are rotatably installed at the four corners of the upper end of the window frame 1, and lock holes 10 adapted to the locking blocks 6 are opened at the four corners of the window sash 2, and a transmission mechanism for synchronously rotating four groups of locking blocks 6 is arranged in the window frame 1;

[0033] The transmission mechanism includes a connecting shaft 4 vertically installed at the four corners of the upper end of the window frame 1 through a bearing, the upper end of the connecting shaft 4 is fixedly connected to the lower end of the locking block 6, a first motor 5 is fixedly installed at the outer end of the window frame 1, and the output end of the first motor 5 is fixedly connected to the lower end of one group of connecting shafts 4. Two groups of first transmission rods 7 and one group of second transmission rods 8 are symmetrically installed in the window frame 1 through bearings, and bevel gears 9 are installed at the lower end of the connecting shaft 4, both ends of the first transmission rod 7, and both ends of the second transmission rod 8. The two groups of first transmission rods 7 are transmitted to the second transmission rod 8 through the bevel gears 9;

[0034] like Figures 1 to 3 As shown, two groups of connecting shafts 4 are connected to both ends of the second transmission rod 8 through bevel gears 9. At the same time, the two groups of connecting shafts 4 are connected to the first transmission rod 7 and the other two groups of connecting shafts 4 through bevel gears 9. This structure allows the four groups of locking blocks 6 to rotate symmetrically and synchronously outward, so that they can be inserted into the lock holes 10 at the same time to close and reinforce the window sash 2 and the window frame 1, increase the wind pressure resistance of the device, and at the same time allow the window sash 2 to fit more closely with the sealing pad 12, enhance the sealing effect, and reduce the probability of wind and water seepage.

[0035] The thickness of the locking block 6 is adapted to the width of the locking hole 10, the lower surface of the outer end of the locking block 6 is inclined, and the edge of the outer end of the locking block 6 is arc-shaped;

[0036] like Figure 2 and Figure 4 As shown, this structure ensures that when the locking block 6 rotates, there will be no obvious edges and corners that will scratch the edge of the lock hole 10. At the same time, the inclined lower surface of the outer end is more conducive to aligning it with the lock hole 10 when rotating, which can reduce the probability of failure and avoid unnecessary scratches and friction.

[0037] A fixing frame 13 is provided on the upper side of the sealing rubber pad 12, and a connecting plate 14 is fixedly installed on the upper end of the fixing frame 13. The connecting plate 14 is L-shaped, and the bending part of the connecting plate 14 is arc-shaped. The connecting plate 14 is formed by bending an integrated stainless steel plate;

[0038] like Figure 5 As shown, this structure enables the connecting plate 14 to have good bending strength and a certain ability to withstand deformation, and is not prone to damage and breakage, while ensuring the stability of the connection.

[0039] A driving mechanism for controlling the translation and flipping of the connecting plate 14 is provided at the lower end of the connecting plate 14, and the driving mechanism includes a connecting shaft 15 inserted through the lower end of the connecting plate 14, and the two ends of the connecting shaft 15 are respectively inserted at the two ends of the fixed seat 16 through bearings, and a second motor 17 is fixedly installed at one end of the fixed seat 16, and the output end of the second motor 17 is fixedly connected to one end of the connecting shaft 15, and movable seats 18 are rotatably installed at both ends of the fixed seat 16, and a guide wheel 19 is rotatably installed on the inner side of the movable seat 18, and a third motor 20 is fixedly installed on the outer end of a group of movable seats 18, and the output end of the third motor 20 is fixedly connected to the central axis of a group of guide wheels 19, and a guide rail 21 is opened around the inner side of the sealing convex strip 11, and the guide rail 21 is adapted to the guide wheel 19, and the guide wheel 19 rolls in the guide rail 21, and the inner diameter of the opening of the guide rail 21 is adapted to the outer diameter of the fixed seat 16;

[0040] like Figures 5 to 9 As shown, the length of the power connection line of the second motor 17, the third motor 20 and the fourth motor 25 needs to be greater than the length of the guide rail 21, so as to ensure that the second motor 17, the third motor 20 and the fourth motor 25 can continue to work around the sealing rubber pad 12 for one circle, and after working around for one circle, they need to turn back for a second work, and cannot continue to rotate in one direction for more than one circle. This part of the program is set as a more common method in the prior art, and its basic principle and structure are not described in detail here. This part of the structure allows the roller brush 27 to clean along the surface of the sealing rubber pad 12, thereby ensuring the cleaning effect, and the rotation setting of the two sets of movable seats 18 allows this part of the structure to pass smoothly when passing the bending part of the sealing rubber pad 12, and the guide wheel 19 and the guide rail 21 can adopt the annular guide rail guide wheel in the prior art to ensure the normal operation of the device.

[0041] A roller brush 27 is rotatably mounted on the inner side of the fixing frame 13, and the bristles of the roller brush 27 are in contact with the upper surface of the sealing rubber pad 12. A fourth motor 25 for driving the roller brush 27 to rotate is fixedly mounted at one end of the fixing frame 13. The fourth motor 25 needs to ensure that the roller brush 27 can rotate outwards, that is, Figure 5 As shown, the roller brush 27 needs to clean the impurities on the surface of the sealing rubber pad 12 toward the outside by rotating, so as to prevent the impurities from falling into the room. The two ends of the roller brush 27 are connected to the fixed frame 13 through a sliding assembly. The sliding assembly includes a slide groove 22 symmetrically opened at both ends of the fixed frame 13. A slider 23 is slidably arranged in the slide groove 22. The slider 23 is square, and its outer diameter is adapted to the inner diameter of the slide groove 22.

[0042] like Figure 7 , Fig.10 and Fig.11As shown, limiting protrusions are provided at both ends of the slider 23, and limiting guide grooves matched with the limiting protrusions are provided on both sides of the slide groove 22, so that the slider 23 can slide in the slide groove 22 but cannot escape or rotate, thereby ensuring the stability of the roller brush 27, and the sliding assembly allows the roller brush 27 to fall naturally by gravity when it is on the upper side of the sealing pad 12, so as to ensure that the bristles of the roller brush 27 can fit with the sealing pad 12 and be in contact with the force, thereby increasing the cleaning force and effect, and avoiding the problem of cleaning dead corners caused by shortened bristle loss.

[0043] Both ends of the roller brush 27 are provided with connection components for easy disassembly and assembly, and the connection components include a connection sleeve block 24 rotatably installed in the slider 23, and the connection sleeve block 24 is fixedly connected to the output end of the fourth motor 25. A connector 28 is fixedly provided at the center position of one end of the roller brush 27, and the connector 28 is in an outer hexagonal shape. A slot 26 adapted to the connector 28 is provided at the end of the connection sleeve block 24 away from the fourth motor 25, and the end edge of the connection head 28 and the opening edge of the groove of the connection sleeve block 24 are both provided with rounded corners. A movable groove 29 is provided at the other end of the roller brush 27, and a spring 30 is transversely arranged in the movable groove 29. A cylindrical limiting block 31 is movably installed at the opening of the movable groove 29, and the inner end of the cylindrical limiting block 31 is abutted against the end of the spring 30. A limiting circular hole 32 adapted to the cylindrical limiting block 31 is transversely provided at the center position of the slider 23 away from the fourth motor 25, and the end edge of the limiting circular hole 32 and the opening edge of the slider 23 are both provided with rounded corners.

[0044] like Fig.10 As shown, the structure is used for disassembling and replacing the roller brush 27. When it is too worn to be used, the cylindrical limit block 31 can be pressed inwardly so that the cylindrical limit block 31 is received in the movable groove 29 and the spring 30 is compressed. After the cylindrical limit block 31 is disengaged from the limiting circular hole 32, the roller brush 27 is tilted and pulled out so that the connecting head 28 is disengaged from the slot 26. During installation, the connecting head 28 on the roller brush 27 is first aligned with the slot 26 on the connecting sleeve block 24 and inserted, and then the cylindrical limit block 31 is pressed inwardly so that it is received in the movable groove 29 and the spring 30 is compressed. Then, the roller brush 27 is horizontally placed between the two sets of sliders 23, and after the cylindrical limit block 31 is aligned with the limiting circular hole 32, the spring 30 will push the cylindrical limit block 31 to reset through the restoring force, so that it is inserted into the limiting circular hole 32. At this time, the roller brush 27 is installed, with a simple structure and convenient operation.

[0045] A toothed comb plate 37 is provided on the upper side of the roller brush 27, a connecting frame 33 is symmetrically provided on the upper side of the inner ends of the two groups of sliders 23, a fixed shaft 34 is transversely provided on the inner side of the connecting frame 33, a torsion spring 35 is sleeved on the fixed shaft 34, and a fixing block 36 is symmetrically provided on both sides of the upper end of the toothed comb plate 37, and the two groups of fixing blocks 36 are respectively rotatably sleeved on the two groups of fixing shafts 34, and the two ends of the torsion spring 35 are respectively fixedly connected to the fixing block 36 and the connecting frame 33, and the longitudinal section of the toothed comb plate 37 is in the shape of an arc, and the tooth-like parts of the edges of the toothed comb plate 37 are equidistantly arranged and are composed of arc-shaped cylinders, and the ends of the tooth-like parts are hemispherical, and the tooth-like parts of the toothed comb plate 37 are drooped and tilted downward to fit close to the surface of the toothed comb plate 37;

[0046] like Figure 7 and Fig.11 As shown, this structure allows the toothed comb plate 37 to comb the bristles of the roller brush 27 through its toothed part when the roller brush 27 rotates, thereby removing impurities such as wire rods stuck or entangled on the bristles, so that the roller brush 27 can be used well for a certain period of time. At the same time, since the two groups of fixed blocks 36 at the upper end of the toothed comb plate 37 are rotatably sleeved on the fixed shaft 34, and the two ends of the torsion spring 35 are connected to the connecting frame 33 and the fixed block 36, the toothed comb plate 37 will receive the force of the torsion spring 35 for support and limitation. When it is subjected to force, it will tilt and rotate, and will be reset through the torsion spring 35 when the force is reduced or disappears. This can avoid excessive jamming when combing the roller brush 27.

[0047] Working principle: When in use, before the electric push rod 3 drives the window sash 2 to close, it is necessary to ensure that the connecting plate 14 is on the inner side of the window frame 1, that is, in the retracted state, and when the window sash 2 is closed, Figure 2 After the state shown, the first motor 5 can be controlled to drive a group of connecting shafts 4 to rotate, and the group of connecting shafts 4 drives a group of first transmission rods 7 and a second transmission rod 8 to rotate through the bevel gear 9, and the second transmission rod 8 drives another group of first transmission rods 7 to rotate through the bevel gear 9. When the two groups of first transmission rods 7 rotate synchronously, the four groups of connecting shafts 4 will synchronously drive the locking block 6 to rotate outward, so as to be inserted into the lock hole 10 on the window sash 2 to press and fix it, thereby increasing its stability and tightness;

[0048] Before closing the window, the second motor 17 can be controlled to start, so that the second motor 17 drives the connecting plate 14 to rotate through the connecting shaft 15, so that the connecting plate 14 drives the fixing frame 13 to rotate to the upper side of the sealing rubber pad 12, such as Figure 5As shown, the roller brush 27 will fall on the sealing gasket 12, and then the third motor 20 and the fourth motor 25 can be turned on. The third motor 20 will drive a group of guide wheels 19 to roll along the guide rail 21, thereby driving the fixing seat 16 to cooperate with another group of guide wheels 19 to move along the guide rail 21, and when the fourth motor 25 is working, it will drive the roller brush 27 to rotate outward to clean impurities such as dust and fallen leaves on the surface of the sealing gasket 12, reduce the residual impurities on its surface, so as to avoid squeezing impurities when closing the window to cause unnecessary wear on the sealing gasket 12, and also avoid the situation that the sealing gasket 12 and the window sash 2 cannot fit tightly due to impurities, resulting in air infiltration and water seepage. After cleaning, the second motor 17 drives the connecting plate 14 to flip downward, so that the fixing frame 13 and the components above it are flipped to the inside of the window frame 1 for storage, as shown in FIG. Figure 6 As shown, the window closing operation can then begin. The above is the entire working principle of the present invention.
