Description

Technical Field

[0001] This invention relates to the field of alarm equipment, specifically an alarm device for industrial intelligent lighting. Background Technology

[0002] Factory buildings, warehouses, and other similar locations typically have ceilings that are much higher than those in ordinary buildings. However, their lighting equipment and smoke detectors are installed on the ceiling, just like in ordinary buildings. Due to the height factor, when a fire occurs on the ground inside the building and smoke is generated, much of the smoke has already dissipated by the time it reaches a higher point, and its direction of dispersal is difficult to determine. This makes it difficult to issue timely alarms through smoke detectors, and the range of alarm information they can provide is extremely limited, resulting in significant limitations. Summary of the Invention

[0003] The purpose of this invention is to provide an alarm device for industrial intelligent lighting to solve the above-mentioned problems.

[0004] The above-mentioned technical objective of the present invention is achieved through the following technical solution: an alarm device for industrial intelligent lighting, comprising a lampshade, an inner lampshade, a support column fixedly mounted on the top end face of the lampshade, a retraction mechanism mounted on the support column, the retraction mechanism comprising a fixed cover fixedly mounted on the support column, a rotating cover rotatably mounted on the support column, the top end of the rotating cover rotatably connected to the inner wall of the bottom side of the fixed cover, a first gear rotatably mounted on the support column and located inside the rotating cover, two electric telescopic rods symmetrically mounted on the bottom end face of the first gear, a rotating cylinder rotatably mounted on the support column and located on the bottom side of the first gear via a bearing, a rotating block slidably mounted on the rotating cylinder, a keyway opened on the rotating cylinder, a connecting key slidably mounted in the keyway and fixedly connected to the rotating block, two suction chambers symmetrically opened on the top end face of the rotating block, a grid plate fixedly mounted at the opening position of the suction chamber, the telescopic rod ends of the electric telescopic rods fixedly connected to the grid plate, an air pump fixedly mounted on the bottom wall of the suction chamber, and a suction pipe penetrating and fixedly installed at the bottom of the suction chamber. The top end of the suction tube is connected to the suction port of the air pump. The two suction tubes are alternately wound around the rotating cylinder. The bottom inner wall of the rotating cover is symmetrically provided with through holes. A fixing rod is fixedly provided on the circumferential end face of the rotating cover near the through hole. A fixing ring is fixedly provided on the end of the fixing rod away from the rotating cover. The suction tube passes through the through hole and the fixing ring on one side. A suction head is fixedly provided at the end of the suction tube. A distance measuring sensor is provided at the end of the suction head. A rotating mechanism is provided inside the fixing cover and the rotating cover. The rotating mechanism drives the rotation of the rotating cover and the first gear. When the first gear rotates, it cooperates with the retraction of the electric telescopic rod to realize the control of the extension and retraction of the suction tube. When the suction tube is extended a certain distance, the rotating cover drives the suction tube to rotate. Under the action of centrifugal force, the suction head moves away from the lamp cover, so that a larger range of suction can be performed when the air pump is working. A locking mechanism is provided inside the rotating cover to restrict the relative rotation between the first gear and the support column.

[0005] Preferably, a smoke sensor is fixedly installed on the inner top wall of the rotating cover, and a control module is fixedly installed on the inner top wall of the fixed cover.

[0006] Preferably, the rotating mechanism includes a first motor fixedly mounted on the inner top wall of the rotating cover, a second gear fixedly mounted on the motor shaft of the first motor, the second gear meshing with the first gear, an end face gear fixedly mounted on the top end face of the rotating cover, a fixing block fixedly mounted on the inner top wall of the fixed cover, a second motor fixedly mounted on the bottom end of the fixing block, and a fourth gear fixedly mounted on the motor shaft of the second motor, the fourth gear meshing with the end face gear.

[0007] Preferably, the locking mechanism includes a third gear fixedly mounted on the support column and located between the electric telescopic rods. Each electric telescopic rod has two symmetrically arranged connecting blocks. A flipping rod is rotatably mounted on each connecting block. A locking block is fixedly mounted on the end of the flipping rod away from the connecting block. The locking block can engage with the teeth of the third gear. Electromagnets are symmetrically arranged on the electric telescopic rod near the third gear. A spring is fixedly connected between the electromagnets and the flipping rod.

[0008] In summary, the present invention has the following beneficial effects: by coordinating the extension and retraction mechanism with the rotation mechanism, the length of the suction tube can be controlled intermittently during normal lighting use. Centrifugal force causes the suction head to lift the end of the suction tube. By controlling the speed of the second motor in the rotation mechanism, the height position and rotation radius of the suction tube end can be controlled and changed, thereby effectively controlling and changing the suction range, expanding the monitoring area, and compensating for the problem of decreased monitoring sensitivity caused by height position. This allows the smoke alarm to detect fires in the factory in a timely and effective manner, increasing reliability. Attached Figure Description

[0016] Combined with appendix Figures 1-5An alarm device for industrial intelligent lighting includes a lampshade 11, with a lighting lamp 12 disposed inside the lampshade 11. A support column 13 is fixedly disposed on the top end face of the lampshade 11, and a retraction mechanism is provided on the support column 13. The retraction mechanism includes a fixed cover 14 fixedly disposed on the support column 13, and a rotating cover 15 rotatably disposed on the support column 13. The top end of the rotating cover 15 is rotatably connected to the bottom inner wall of the fixed cover 14. A first gear 16 is rotatably disposed on the support column 13 and located inside the rotating cover 15. Two electric telescopic rods 17 are symmetrically fixed on the bottom end face of the first gear 16. A rotating cylinder 41 is mounted on the bottom side of the first gear 16 and rotatably mounted on a bearing. A rotating block 18 is slidably mounted on the rotating cylinder 41. A keyway 42 is provided on the rotating cylinder 41, and a connecting key 43 fixedly connected to the rotating block 18 is slidably mounted in the keyway 42. Two suction chambers 40 are symmetrically opened on the top end face of the rotating block 18. A grid plate 19 is fixedly mounted at the opening of the suction chamber 40. The end of the telescopic rod of the electric telescopic rod 17 is fixedly connected to the grid plate 19. An air pump 21 is fixedly mounted on the bottom wall of the suction chamber 40. A suction pipe 20 is fixedly mounted through and fixedly installed at the bottom of the suction chamber 40. The top of the suction pipe 20... The end is connected to the suction port of the air pump 21. Two suction tubes 20 are alternately wound around the rotating cylinder 41. The bottom inner wall of the rotating cover 15 is symmetrically provided with through holes 22. A fixing rod 23 is fixedly provided on the circumferential end face of the rotating cover 15 near the through hole 22. A fixing ring 24 is fixedly provided at the end of the fixing rod 23 away from the rotating cover 15. The suction tube 20 passes through the through hole 22 and the fixing ring 24 on one side. A suction head 25 is fixedly provided at the end of the suction tube 20. A distance measuring sensor is provided at the end of the suction head 25. The fixed cover 14 and the rotating cover 15 are equipped with A rotating mechanism drives the rotation of the rotating cover 15 and the first gear 16. When the first gear 16 rotates, it cooperates with the retraction of the electric telescopic rod 17 to control the extension and retraction of the suction tube 20. When the suction tube 20 is extended a certain distance, the rotating cover 15 drives the suction tube 20 to rotate. Under the action of centrifugal force, the suction head 25 moves away from the lamp cover 11, so that a larger range of suction can be performed when the air pump 21 is working. The rotating cover 15 is provided with a locking mechanism to restrict the relative rotation between the first gear 16 and the support column 13.

[0017] Advantageously, the suction head 25 has a large mass so that when the rotating cover 15 rotates, the suction head 25 can tighten the suction tube 20 under centrifugal force and cause the end of the suction tube 20 to fly up.

[0018] Advantageously, a smoke sensor 34 is fixedly installed on the inner top wall of the rotating cover 15, and a control module 39 is fixedly installed on the inner top wall of the fixed cover 14.

[0019] Advantageously, the rotating mechanism includes a first motor 26 fixedly mounted on the inner top wall of the rotating cover 15, a second gear 27 fixedly mounted on the motor shaft of the first motor 26, the second gear 27 meshing with the first gear 16, an end face gear 35 fixedly mounted on the top end face of the rotating cover 15, a fixing block 36 fixedly mounted on the inner top wall of the fixing cover 14, a second motor 37 fixedly mounted on the bottom end of the fixing block 36, a fourth gear 38 fixedly mounted on the motor shaft of the second motor 37, the fourth gear 38 meshing with the end face gear 35.

[0020] Advantageously, the locking mechanism includes a third gear 28 fixedly mounted on the support column 13 and located between the electric telescopic rods 17. Each electric telescopic rod 17 is symmetrically provided with two connecting blocks 29. A flipping rod 30 is rotatably mounted on the connecting block 29. A locking block 31 is fixedly mounted on the end of the flipping rod 30 away from the connecting block 29. The locking block 31 can be engaged between the teeth of the third gear 28. An electromagnet 32 ​​is symmetrically provided on the electric telescopic rod 17 near the third gear 28. A spring 33 is fixedly connected between the electromagnet 32 ​​and the flipping rod 30.

[0021] Advantageously, the second motor 37 can be a servo motor, controlled by a PLC program, which can periodically change the motor shaft speed of the second motor 37.

[0022] How to use this invention:

[0023] In the initial state: the electric telescopic rod 17 is in the retracted state, the rotating block 18 is in the upper limit position, the electromagnet 32 ​​is in the energized state, the spring 33 is in the compressed state, the locking block 31 is locked between the teeth of the third gear 28 so that the rotating block 18 and the first gear 16 cannot rotate relative to the support column 13, and the two suction tubes 20 are intertwined and wrapped around the support column 13.

[0024] The present invention is fixed to the top of the factory building by the support column 13, and under the action of gravity, the end of the suction head 25 hangs down toward the ground.

[0025] During operation, the control module 39 intermittently activates the retraction mechanism, rotation mechanism, and locking mechanism. When each mechanism activates, based on the distance measured by the distance sensor to the factory floor, the control module 39 matches the required length of the suction tube 20 to be extended according to pre-stored data. The control module 39 first de-energizes the electromagnet 32, causing the flipping rod 30 to rotate under the action of the spring 33, thus preventing the locking block 31 from contacting the third gear 28. Then, the control module 39 activates the first motor 26, which drives the second gear 27 to rotate, thereby rotating the first gear 16 and driving the electric telescopic rod 17 to rotate. The rotating block 18 and the rotating drum 41 rotate accordingly. At the same time, the control module 39 controls the electric telescopic rod 17 to extend, so that while the rotating block 18 and the rotating drum 41 rotate around the support column 13, the rotating block 18 descends along the rotating drum 41, thereby gradually releasing the suction tube 20. After releasing the suction tube 20 to a suitable length according to the value measured by the distance sensor, the control module 39 controls the first motor 26 to stop, and then controls the electromagnet 32 ​​to be energized. Under the attraction of the electromagnet 32, the flipping rod 30 flips, causing the locking block 31 to engage with the third gear 28, restricting the rotation of the first gear 16, the rotating block 18 and the rotating drum 41.

[0026] Then, the control module 39 controls the second motor 37 to start, which drives the fourth gear 38 to start, thereby causing the end face gear 35 and the rotating cover 15 to rotate. The fixed rod 23 and the fixed ring 24 rotate accordingly, and under the action of centrifugal force, the suction head 25 rotates and flies up. The control module 39 can control the speed of the second motor 37 to gradually change, thereby changing the height position of the suction head 25 and the distance between the suction head 25 and the axis of the support column 13. At this time, after the air pump 21 starts, it can effectively expand its suction range. When there is smoke or dust in the air sucked into the rotating cover 15 through the suction head 25 and the suction pipe 20, the smoke or dust triggers the smoke sensor 34, thereby triggering an alarm.

[0027] During reset, the control module 39 stops the air pump 21 and the second motor 37, thereby stopping the rotation of the rotating cover 15. Then, the control module 39 controls the first motor 26 to reverse, causing the second gear 27 to reverse, which in turn causes the first gear 16 to reverse. At the same time, the control module 39 controls the electric telescopic rod 17 to retract. The retraction speed of the electric telescopic rod 17 is adapted to the reversal speed of the first motor 26, thereby causing the rotating block 18 and the rotating drum 41 to reverse. Meanwhile, the rotating block 18 is also rising along the rotating drum 41. The rising of the rotating block 18 pulls the suction tube 20 to retract. Due to the restriction effect of the through hole 22, the position where the suction tube enters the rotating cover 15 allows the two suction tubes 20 to be neatly wound back onto the rotating drum 41.

[0028] The above embodiments are only for illustrating the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand and implement the present invention. They should not be construed as limiting the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
