Description

Technical Field

[0001] This utility model relates to the field of fire protection equipment technology, and in particular to a smart fire protection monitoring and alarm device. Background Technology

[0002] Fire monitoring and alarm equipment is the "nerve ending" of the modern fire safety system. By integrating sensors, communication technology, and intelligent algorithms, it can achieve real-time perception, accurate early warning, and rapid response to fire hazards. It can proactively detect fire hazards and trigger audible and visual alarms.

[0003] In related technologies, chemical plants need to install fire monitoring and alarm equipment to promptly detect fires and provide early warnings. For example, patent CN204066309U provides a fire monitoring and alarm device, including a housing, a main board inside the housing, a control module on the main board, and a communication module, power supply, display device, and alarm device connected to the control module. The communication module is connected to an external sensor. The power supply includes a power control unit connected to the control module, a power switching button inside the power control unit, and the power control unit is connected to an external power supply and a backup power supply.

[0004] The existing technical solutions described above involve installing audible and visual alarms. When a fire hazard is detected, the alarms emit a warning signal. However, due to severe smoke and dust in some chemical production sites, the surfaces of these alarms become covered in dust after prolonged use, making it impossible for staff to see the lights emitted by the alarms. Consequently, staff cannot promptly detect fire hazards. To address these issues, we propose a smart fire protection monitoring and alarm device. Utility Model Content

[0005] The purpose of this invention is to solve the problem that dust accumulates on the surface of existing sound and light alarms after long-term operation, making it impossible for staff to observe the light emitted by the alarms. Therefore, this invention proposes a smart fire protection monitoring and alarm device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A smart fire protection monitoring and alarm device includes a bracket, a monitoring camera is fixedly installed on the upper end of the bracket, a lamp holder is fixedly installed on the bracket, an audible and visual alarm light is fixedly installed on the lamp holder, the audible and visual alarm light is electrically connected to an external fire alarm controller, a lamp cover is provided on the outside of the audible and visual alarm light, the upper end of the lamp cover is rotatably installed on the bottom of the lamp holder, and the outer side of the lamp cover is set as an arc surface.

[0008] A bushing is rotatably mounted on the bracket, and a first gear ring is fixedly mounted on the lower end of the bushing. A second gear ring is fitted and fixedly mounted on the lampshade, and the second gear ring meshes with the first gear ring. A rubber ring is provided on one side of the lampshade, and a cotton ring is fitted and fixedly connected to the rubber ring. The outer side of the cotton ring contacts the surface of the lampshade. A support mechanism is provided on the bracket, and the rubber ring is mounted on the support mechanism.

[0009] Preferably, the bracket is provided with a drive mechanism, which is connected to the bushing and used to drive the lampshade to rotate.

[0010] Preferably, the drive mechanism includes a third gear ring sleeved on the upper end of the bushing, the third gear ring being fixedly connected to the bushing, a servo motor being fixedly mounted on the bracket, and a drive wheel being fixedly mounted on the output shaft end of the servo motor, the drive wheel meshing with the third gear ring.

[0011] Preferably, the support mechanism includes a cylinder located below the bushing, the lower end of the cylinder is open, the rubber ring is sleeved on the outside of the cylinder, a connecting shaft is fixedly installed on the top of the cylinder, the connecting shaft passes through the bushing and is rotatably mounted on the bracket, a stepper motor is fixedly installed on the bracket, and the output shaft of the stepper motor is fixedly connected to the connecting shaft.

[0012] Preferably, the cylinder has multiple top blocks arranged in a circular array, the outer end face of each top block is an arc surface, elastic elements are fixedly connected to both sides of each top block, the ends of the elastic elements are fixedly connected to the cylinder, a sealing plug is provided at the lower end of the cylinder, and multiple inclined blocks arranged in a circular array are fixedly installed on the top of the sealing plug.

[0013] Preferably, both the outer surface of the sealing plug and the inner wall of the cylinder are provided with anti-slip textures.

[0014] Preferably, the outer end face of the top block and the outer surface of the cylinder are provided with anti-slip texture.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] By creating friction between the lampshade and the cotton ring, dust on the lampshade surface is separated from the lampshade, preventing excessive dust adhesion. The cotton ring cleaning method effectively removes dust without scratching the lampshade surface. After cleaning, the cotton ring is rotated to contact the lampshade, maintaining its effective cleaning function even after multiple cleaning cycles.

[0017] By inserting the sealing plug into the lower port of the cylinder, the inclined block on the sealing plug moves from bottom to top. The inclined block pushes the top block outward, causing the outer end of the top block to press against the inner side of the rubber ring. This causes the elastic element to deform, thus tightening the rubber ring. The outer end face of the top block and the rubber ring are in close contact, creating significant friction. This makes the rubber ring more stable when installed outside the cylinder and prevents it from deflecting during cleaning. When the sealing plug is removed, the inclined block separates from the top block, and the elastic element's force causes the top block to return to its original position. The rubber ring can then be easily removed from the cylinder, facilitating the replacement of the cotton ring after prolonged use. This design greatly simplifies the replacement and maintenance of the cotton ring. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] Reference Figure 1-6 A smart fire protection monitoring and alarm device includes a bracket 1, which is mounted on a wall using expansion bolts. A monitoring camera 2 is fixedly mounted on the upper end of the bracket 1. A lamp holder 3 is fixedly mounted on the bracket 1, and an audible and visual alarm light 4 is fixedly mounted on the lamp holder 3. The audible and visual alarm light 4 is electrically connected to an external fire alarm controller. A lamp cover 5 is provided around the audible and visual alarm light 4. The upper end of the lamp cover 5 is rotatably mounted on the bottom of the lamp holder 3, and the outer surface of the lamp cover 5 is curved. The lamp cover 5 protects the audible and visual alarm light 4 inside.

[0028] The scene is monitored in real time by surveillance camera 2, and the audible and visual alarm light 4 is directly activated by the fire alarm controller. After the fire is confirmed at the fire control center, the alarm is triggered through signal transmission.

[0029] A bushing 6 is rotatably mounted on the bracket 1. A first gear ring 7 is fixedly mounted on the lower end of the bushing 6. A second gear ring 8 is fitted and fixedly mounted on the lampshade 5. The second gear ring 8 meshes with the first gear ring 7. A rubber ring 9 is provided on one side of the lampshade 5. A cotton ring 10 is fitted and fixedly connected on the rubber ring 9. The outer side of the cotton ring 10 contacts the surface of the lampshade 5. A support mechanism is provided on the bracket 1. The rubber ring 9 is mounted on the support mechanism.

[0030] The bracket 1 is equipped with a drive mechanism, which is connected to the bushing 6 and is used to drive the lamp cover 5 to rotate. The drive mechanism includes a third gear ring 11 sleeved on the upper end of the bushing 6. The third gear ring 11 is fixedly connected to the bushing 6. A servo motor 12 is fixedly installed on the bracket 1. A drive wheel 13 is fixedly installed on the output shaft end of the servo motor 12. The drive wheel 13 meshes with the third gear ring 11.

[0031] The support mechanism includes a cylinder 14 located below the bushing 6. The lower end of the cylinder 14 is open. A rubber ring 9 is fitted over the cylinder 14. A connecting shaft 15 is fixedly installed on the top of the cylinder 14. The connecting shaft 15 passes through the bushing 6 and is rotatably mounted on the bracket 1. A stepper motor 16 is fixedly installed on the bracket 1. The output shaft of the stepper motor 16 is fixedly connected to the connecting shaft 15.

[0032] By setting the outer side of the cotton ring 10 to contact the surface of the lampshade 5, the servo motor 12 drives the drive wheel 13 to rotate, which in turn drives the third gear ring 11 to rotate. The third gear ring 11, the bushing 6, and the first gear ring 7 rotate synchronously. The first gear ring 7 drives the second gear ring 8 to rotate, and the second gear ring 8 rotates synchronously with the lampshade 5. The cotton ring 10 remains fixed, and friction is generated between the lampshade 5 and the cotton ring 10, which can separate the dust on the surface of the lampshade 5 from the lampshade 5, preventing excessive dust from adhering to the surface of the lampshade 5. At the same time, the cleaning method of the cotton ring 10 can remove dust without scratching the surface of the lampshade 5.

[0033] After cleaning, dust adheres to the contact point between the cotton ring 10 and the lampshade 5, making it difficult to continue cleaning. The stepper motor 16 drives the connecting shaft 15 to rotate intermittently at a certain angle. The connecting shaft 15 then rotates the cylinder 14, which in turn rotates the rubber ring 9 and the cotton ring 10 synchronously. This causes another part of the cotton ring 10 to rotate and come into contact with the lampshade 5, ensuring effective cleaning even after multiple cleaning cycles. When the stepper motor 16 stops, it remains in a self-locking state, keeping both the cylinder 14 and the cotton ring 10 in a fixed position.

[0034] Based on Example 1, Example 2:

[0035] Reference Figure 2-6 Multiple top blocks 17 arranged in a circular array are threaded through the cylinder 14. The outer end face of each top block 17 is arc-shaped. Elastic members 18 are fixedly connected to both sides of each top block 17, with their ends fixedly connected to the cylinder 14. A sealing plug 19 is provided at the lower end of the cylinder 14, and multiple inclined blocks 20 arranged in a circular array are fixedly installed on the top of the sealing plug 19. Anti-slip textures are provided on the outer surface of the sealing plug 19 and the inner wall of the cylinder 14 to prevent the sealing plug 19 from easily falling out when inserted into the lower end of the cylinder 14. Anti-slip textures are also provided on the outer end face of the top blocks 17 and the outer surface of the cylinder 14.

[0036] By placing the sealing plug 19 into the lower port of the cylinder 14, the inclined block 20 on the sealing plug 19 moves from bottom to top. The inclined block 20 pushes the top block 17 to move outward, so that the outer end of the top block 17 squeezes the inner side of the rubber ring 9. The elastic element 18 stretches and accumulates elastic potential energy, thereby tightening the rubber ring 9. The outer end face of the top block 17 is in close contact with the rubber ring 9. There is a large friction between the two, which makes the rubber ring 9 more stable when installed outside the cylinder 14, and it is not easy to deflect during the cleaning process and remains stable.

[0037] When the sealing plug 19 is removed, the inclined block 20 separates from the top block 17, the elastic element 18 returns to its original state, and the top block 17 is pulled back to reset. The rubber ring 9 outside the cylinder 14 can be removed relatively easily, and the cotton ring 10 can be replaced after long-term use. The above design brings convenience to the replacement and maintenance of the cotton ring 10.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
