Description

Technical Field

[0001] The invention belongs to the technical field of alarm devices, and in particular relates to an anti-pollution alarm for industrial plants. Background Art

[0002] Regardless of the industry, the most important thing in work is safety. Especially for the manufacturing industry, safety is particularly important. Therefore, many alarms are installed in factories, workshops and machine rooms. Once an accident occurs, the alarm needs to flash and alarm at the first time and be handled by the staff.

[0003] At present, since the lamp body of a general alarm is set outside, its only protective mechanism is the external plastic shell. However, since there are many mechanical devices in a general industrial machine room, a large amount of dust and pollutants in the outside air are raised in the state of continuous operation, and then dispersed with the air flow. As more and more dust and pollutants are attached to the outside of the lamp body, the light of the lamp body obscured by the dust on the outer wall will become weaker and weaker when the alarm flashes, which will greatly reduce the use effect of the lamp body and shorten the service life of the lamp body.

[0004] Furthermore, since the lamp body is generally hung at a higher position, it is convenient for staff to observe. However, due to its high height, when cleaning the lamp body, staff need to climb to the position of the lamp body, resulting in a very labor-intensive cleaning process and a high risk of high-altitude operations. Summary of the invention

[0005] The purpose of the present invention is to address the problem that the alarm in the prior art is easily contaminated, and to propose an anti-pollution alarm for industrial plants. The anti-pollution alarm for industrial plants can prevent dust from adhering to the surface of the alarm light and affecting the alarm effect.

[0006] The purpose of the present invention can be achieved through the following technical solutions: an anti-pollution alarm for industrial plants, comprising a shell, on which a detection control device, a pushing device and a sealing device are provided, the detection control device is used to detect smoke, so that the alarm sounds an alarm, the detection control device comprises a detection box fixedly provided at the upper end of the shell, a gas plate fixedly provided at the lower opening of the detection box, a controller fixedly provided on the left side of the inner cavity of the detection box, a detector fixedly provided on the right side of the inner cavity of the detection box, a pushing device used to push the alarm light out of the equipment, the pushing device comprises a fixed plate fixedly provided in the middle of the inner cavity, a pushing cavity provided on the upper side of the fixed plate, and an extension provided on the lower side of the fixed plate The shrinkage cavity, the fixed plate is symmetrically rotated with a threaded rod, the middle of the fixed plate is slidably provided with a push rod, the lower end of the push rod is provided with an alarm light, the upper end of the push rod is fixed with an inner push plate, the left and right sides of the inner push plate are fixed with threaded sleeves, each of the threaded sleeves is threadedly engaged with the corresponding threaded rod, the sealing device is used to open the outlet when the alarm light pops out of the device, to ensure that the alarm light pops out of the device smoothly, the sealing device includes a sealing slide groove symmetrically provided on the lower side wall of the shell, each of the sealing slide grooves is slidably provided with a sealing slider, the outer end of each sealing slide groove is fixed with a limit plate, and each sealing slider is connected to the inner side of the corresponding sealing slide groove by a sealing spring.

[0007] Furthermore, the pushing device includes a motor fixedly provided on the middle part of the upper side of the inner cavity of the detection box, a main shaft is provided at the output end of the motor, the main shaft is raised into the inner cavity of the shell, a connecting claw is fixedly provided at the lower end of the main shaft, an internal gear is fixedly provided at the lower end of the connecting claw, a pushing gear is fixedly provided at the upper end of each threaded rod, and each pushing gear is meshed with the internal gear.

[0008] Furthermore, the detector is used to measure the smoke concentration in the factory and feed back the concentration information to the controller, and the controller is used to control the motor to work.

[0009] Furthermore, the sealing device includes a sealing slider on the right side fixed with a concave sealing plate, a fixed wedge rod is fixed on the upper side of the concave sealing plate, a groove is provided in the middle of the concave sealing plate, and the sealing slider on the left side is fixed with a convex sealing plate, another fixed wedge rod is provided on the upper side of the convex sealing plate, and the convex sealing plate is slidably connected in the groove.

[0010] Furthermore, a U-shaped groove is provided on the right end of the concave sealing plate, and a U-shaped groove of the same shape is also provided on the left side of the convex sealing plate. When the alarm light pops out of the device, the convex sealing plate and the concave sealing plate slide into the corresponding sealing groove respectively, and the U-shaped grooves on the convex sealing plate and the concave sealing plate overlap in reverse to form a circle, and the diameter of the circular groove is slightly larger than the diameter of the alarm light.

[0011] Furthermore, the sealing device includes an outer push plate fixedly provided in the middle of the push rod, an outer slide cylinder symmetrically fixedly provided on the lower side of the outer push plate, a sliding lever sliding inside each of the outer slide cylinders, a threaded limiting ring threadedly engaged with the outer end of each outer slide cylinder, and a thrust spring connected between each sliding lever and the corresponding outer slide cylinder.

[0012] Furthermore, the lower end of the sliding latch rod is an inclined surface, the inclined surface angle of the sliding latch rod is the same as the inclined surface angle of the fixed latch rod, and each sliding latch rod cooperates with the corresponding fixed latch rod.

[0013] Furthermore, the elastic coefficient of the threaded limiting ring is greater than the elastic coefficient of the sealing spring, that is, when the sliding lever moves downward, the thrust spring is first pushed to drive the sealing slider to compress the sealing spring.

[0014] When the detector detects that the smoke concentration is too high, it feeds back the data to the controller. The controller controls the alarm light to sound an alarm and controls the motor to rotate forward at the same time. The output end of the motor drives the main shaft to rotate. When the main shaft rotates, it drives the connecting claw to rotate. The connecting claw drives the lower inner gear to rotate. The two push gears mesh and rotate with the inner gear, and the two push gears rotate in the same direction, so that the push gear drives the corresponding threaded rod to rotate in the fixed plate. When the two fixed plates rotate, since the threaded sleeve is threadedly engaged with the threaded rod, the threaded rod drives the inner push plate downward through the threaded sleeve, so that the inner push plate pushes the push rod to drive the alarm light to move downward, and at the same time, the push rod drives the outer push plate to move downward, and the outer push plate drives the sliding wedge rod in the outer slide tube to move downward. At this time, the sliding wedge rod does not slide under the elastic force of the thrust spring, so the sliding wedge rod The rod cooperates with the fixed wedge rod to drive the corresponding fixed wedge rod to slide into the sealing slide groove to compress the sealing spring. As the sliding wedge rod continues to move downward, the sliding wedge rod disengages from the fixed wedge rod, and the sliding wedge rod presses against the corresponding convex sealing plate and concave sealing plate. At this time, the sliding wedge rod clamps the corresponding fixed wedge rod, that is, the sealing slider stops sliding. At this time, the U-shaped grooves at the convex sealing plate and the concave sealing plate form a circle. When a fire occurs, the alarm light is driven to move downward quickly through the pushing mechanism, and with the cooperation of the sliding wedge rod and the thrust spring, the outlet of the equipment is opened, ensuring the smooth pop-up of the alarm light. At the same time, with the cooperation of the convex sealing plate and the concave sealing plate, when no fire occurs, the outlet of the equipment remains closed, and the alarm light is inside the equipment, ensuring the lighting intensity of the alarm light.

[0015] As the push rod continues to move downward, the sliding wedge rod remains stationary, compressing the thrust spring, and the alarm light pops out from the circular groove formed between the convex sealing plate and the concave sealing plate, exposing it to the outside world and giving a flashing alarm. When the smoke disappears, the controller controls the motor to reverse, thereby pushing the inner push plate of the device to drive the push rod to pull the threaded rod to retract into the equipment, and the sliding wedge rod disengages from the fixed wedge rod, and the fixed wedge rod is reset under the elastic force of the corresponding sealing spring. The convex sealing plate and the concave sealing plate close the equipment outlet again to prevent the alarm light from receiving dust in the factory adhering to the surface of the alarm light and affecting the warning range. The convex sealing plate and the concave sealing plate are in a compressed state, and the corresponding two U-shaped notches form a circular arc notch, which cooperates with the alarm light to prevent dust from entering the equipment, thereby ensuring the alarm effect.

[0026] like Figure 1 As shown, the detector 16 is used to measure the smoke concentration in the factory and feed back the concentration information to the controller 15, and the controller 15 is used to control the motor 13 to work.

[0027] like Figure 1 , Figure 6 As shown, the sealing device includes a right sealing slider 32 fixed with a concave sealing plate 36, a fixed lever 38 is fixed on the upper side of the concave sealing plate 36, and a groove 37 is provided in the middle of the concave sealing plate 36; a left sealing slider 32 is fixed with a convex sealing plate 35, another fixed lever 38 is provided on the upper side of the convex sealing plate 35, and the convex sealing plate 35 is slidably connected in the groove 37.

[0028] like Figure 6 As shown, a U-shaped notch is provided on the right end of the concave sealing plate 36, and a U-shaped notch of the same shape is also provided on the left side of the convex sealing plate 35. When the alarm light 30 pops out of the device, the convex sealing plate 35 and the concave sealing plate 36 slide into the corresponding sealing groove 31 respectively, and the U-shaped notches on the convex sealing plate 35 and the concave sealing plate 36 overlap in reverse to form a circle, and the diameter of the circular notch is slightly larger than the diameter of the alarm light 30.

[0029] like Figure 1 , Figure 4 As shown, the sealing device includes an outer push plate 25 fixed in the middle of the push rod 22, and outer slide cylinders 26 are symmetrically fixed on the lower side of the outer push plate 25. A sliding lever 27 is slidably provided inside each outer slide cylinder 26, and a threaded limiting ring 29 is threadedly engaged with the outer end of each outer slide cylinder 26. A thrust spring 28 is connected between each sliding lever 27 and the corresponding outer slide cylinder 26.

[0030] like Figure 1 As shown, the lower end of the sliding lever 27 is an inclined surface, and the inclined surface angle of the sliding lever 27 is the same as the inclined surface angle of the fixed lever 38. Each sliding lever 27 cooperates with the corresponding fixed lever 38.

[0031] like Figure 4 , Figure 5 As shown, the elastic coefficient of the threaded limiting ring 29 is greater than the elastic coefficient of the sealing spring 34, that is, when the sliding lever 27 moves downward, the thrust spring 28 is first pushed to drive the sealing slider 32 to compress the sealing spring 34.

[0032] When the detector 16 detects that the smoke concentration is too high, the data is fed back to the controller 15. The controller 15 controls the alarm light 30 to sound an alarm and controls the motor 13 to rotate forward at the same time. The output end of the motor 13 drives the main shaft 14 to rotate. When the main shaft 14 rotates, it drives the connecting claw 17 to rotate. The connecting claw 17 drives the lower inner gear 18 to rotate, and the two pushing gears 21 mesh with the inner gear 18 and rotate, and the two pushing gears 21 rotate in the same direction, so that the pushing gear 21 drives the corresponding threaded rod 20 to rotate in the fixed plate 19. When the two fixed plates 19 rotate, since the threaded sleeve 24 is threadedly engaged with the threaded rod 20, the threaded rod 20 drives the inner push plate 23 to move downward through the threaded sleeve 24, so that the inner push plate 23 pushes the push rod 22 to drive the alarm light 30 to move downward, and at the same time, the push rod 22 drives the outer push plate 25 to move downward, and the outer push plate 25 drives the sliding wedge rod 27 in the outer slide cylinder 26 to move downward. At this time, the sliding wedge rod 27 is under the elastic force of the thrust spring 28 The sliding lever 27 does not slide, so the sliding lever 27 cooperates with the fixed lever 38 to drive the corresponding fixed lever 38 to drive the corresponding sealing slider 32 to slide into the sealing slide groove 31, compressing the sealing spring 34. As the sliding lever 27 continues to move downward, the sliding lever 27 is separated from the fixed lever 38, and the sliding lever 27 is pushed onto the corresponding convex sealing plate 35 and the concave sealing plate 36. At this time, the sliding lever 27 blocks the corresponding fixed lever 38, that is, the sealing slider 32 does not slide. The U-shaped grooves at the convex sealing plate 35 and the concave sealing plate 36 form a circle. When a fire occurs, the warning light 30 is driven to move downward quickly through the pushing mechanism, and the cooperation of the sliding lever 27 and the thrust spring 28 opens the outlet of the equipment, ensuring the smooth pop-up of the warning light 30. At the same time, with the mutual cooperation of the convex sealing plate 35 and the concave sealing plate 36, when no fire occurs, the outlet of the equipment remains closed, and the warning light 30 is inside the equipment, ensuring the lighting intensity of the warning light 30.

[0033] As the push rod 22 continues to move downward, the sliding wedge rod 27 does not move, compressing the thrust spring 28, and the alarm light 30 pops out from the circular groove formed between the convex sealing plate 35 and the concave sealing plate 36, exposing it to the outside world and performing a flashing alarm. When the smoke disappears, the controller 15 controls the motor 13 to reverse, thereby pushing the inner push plate 23 of the device to drive the push rod 22 to pull the threaded rod 20 to retract into the equipment, and the sliding wedge rod 27 disengages from the fixed wedge rod 38, and the fixed wedge rod 38 is reset under the elastic force of the corresponding sealing spring 34. The convex sealing plate 35 and the concave sealing plate 36 close the equipment outlet again to prevent the alarm light 30 from receiving dust in the factory adhering to the surface of the alarm light 30 and affecting the warning range. The convex sealing plate 35 and the concave sealing plate 36 are in a compressed state, and the corresponding two U-shaped notches form an arc notch, which cooperates with the alarm light 30 to prevent dust from entering the equipment, thereby ensuring the alarm effect.

[0034] Compared with the prior art, the anti-pollution alarm for industrial plants has the following advantages:

[0035] 1. When a fire occurs, the warning light is driven downward quickly through the pushing mechanism, and the exit of the equipment is opened with the cooperation of the sliding lever and the thrust spring, ensuring the smooth pop-up of the warning light.

[0036] 2. At the same time, with the cooperation of the convex sealing plate and the concave sealing plate, when no fire occurs, the equipment outlet remains closed and the alarm light is inside the equipment, ensuring the lighting intensity of the alarm light.

[0037] 3. When the convex sealing plate and the concave sealing plate are in a compressed state, the corresponding two U-shaped notches form an arc notch, which cooperates with the alarm light to prevent dust from entering the interior of the equipment, thereby ensuring the alarm effect.
