Description

Technical Field

[0001] This utility model relates to the field of electric roller shutter technology, and in particular to a protective device for electric roller shutters. Background Technology

[0002] An electric rolling shutter machine is an electromechanical device used in agricultural greenhouses or similar facilities. Its core function is to automatically roll up or down the insulation blankets or shade curtains covering the greenhouse roof using electric power, replacing traditional manual operation. It typically consists of a motor, reducer, roller, transmission device, and control system. During operation, the motor drives the reducer to decrease speed and increase torque, which in turn drives the roller to rotate, evenly rolling up or unfolding the insulation blankets or curtains. This allows for precise regulation of light, temperature, and ventilation within the greenhouse. This equipment not only significantly reduces labor intensity and improves management efficiency but also enables intelligent control through timer or remote control functions, effectively ensuring the stability of the crop growth environment. It is one of the important tools for improving automation levels in modern facility agriculture.

[0003] Currently available electric roller shutters typically lack necessary safety features, especially in emergencies such as fires. They cannot automatically extinguish fires or effectively prevent the spread of fire, making it difficult to ensure the safety of people and property. This functional limitation poses significant safety hazards in practical applications and fails to meet the higher safety requirements of modern buildings. Utility Model Content

[0004] One objective of this invention is to provide a protective device for electric roller shutters. This invention addresses the problem mentioned in the background that existing electric roller shutters typically lack necessary protective functions during use, especially in emergencies such as fires. They are unable to automatically extinguish fires or effectively prevent the spread of fire, making it difficult to ensure the safety of personnel and property. This functional limitation poses significant safety hazards in practical applications and fails to meet the higher safety protection requirements of modern buildings.

[0005] An electric roller shutter protection device according to an embodiment of the present invention includes a wall, a roller shutter assembly, a buffer mechanism, and a protection mechanism. The roller shutter assembly includes a drive housing and a roller shutter door, both of which are installed on the inner side of the wall. The buffer mechanism includes a buffer shell, which is movably installed below the roller shutter door. The protection mechanism includes a high-pressure nozzle, a sealing plug, and a floral diffuser. The high-pressure nozzle is fixedly installed on the upper inner part of the wall, and the floral diffuser is fixedly installed on the lower part of the high-pressure nozzle. The sealing plug is disposed in the outlet of the high-pressure nozzle, and a top rod is fixedly installed on the lower end of the sealing plug.

[0006] Preferably, door handles are fixedly installed on both sides of the buffer shell, and a buffer pad is fixedly installed on the lower surface of the buffer shell.

[0007] Preferably, a sliding groove is formed on the lower inner surface of the buffer shell, a sliding rod is fixedly installed inside the sliding groove, and sliding blocks are slidably installed on both sides of the surface of the sliding rod.

[0008] Preferably, an inner spring is installed on the inner surface of the sliding block, and an outer spring is installed between the outer surface of the sliding block and the inner wall of the sliding groove.

[0009] Preferably, upper rotating seats are fixedly installed on both sides of the lower surface of the roller shutter door, and lower rotating seats are fixedly installed on the upper surface of the sliding block.

[0010] Preferably, a buffer rod is movably installed between the upper rotating seat and the lower rotating seat, with the upper end of the buffer rod rotatably installed inside the upper rotating seat and the lower end of the buffer rod rotatably installed inside the lower rotating seat.

[0011] Preferably, a strip pipe is fixedly installed on the upper inner part of the wall, and the high-pressure nozzle is fixedly installed on the lower surface of the strip pipe.

[0012] Preferably, the flower-shaped diffuser is fixedly installed on the lower surface of the high-pressure nozzle by a connecting rod, and a threaded hole is opened through the surface of the flower-shaped diffuser. A bolt is installed on the inner thread of the threaded hole, and the top rod is fixedly installed on the upper end of the bolt.

[0013] The beneficial effects of this utility model are: This utility model features a protective mechanism installed on the upper sides of both sides of the roller shutter assembly. When a fire occurs inside or outside the roller shutter, the high temperature melts the top rod, and the sealing plug is flushed downwards by the high-pressure water in the high-pressure nozzle. Subsequently, fire-fighting water is sprayed downwards through the high-pressure nozzle, and at the same time, the fire-fighting water is evenly dispersed through the flower-shaped diffuser. The protective mechanism can be reused. When it needs to be reused, the sealing plug is manually placed at the outlet of the high-pressure nozzle, and a new top rod is placed under the sealing plug using bolts. This achieves automatic water spraying for fire extinguishing, with uniform water mist dispersion, and manual reset for reuse, improving fire extinguishing efficiency and the practicality of the device. This invention utilizes a buffer mechanism. When the roller shutter door is lowered to its limit, the buffer shell first contacts the ground. Then, the pressure on the buffer shell is transmitted to the inner spring through the sliding block, causing the inner spring to be compressed while the outer spring is stretched. The restoring force of the inner and outer springs buffers the impact force from the ground on the buffer shell. At the same time, when the buffer shell slides down to its limit, it contacts and impacts the ground through the buffer pad, achieving secondary buffering, reducing equipment wear, extending service life, and improving operational stability and safety.

[0015] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0016] refer to Figure 1-4A protective device for an electric roller shutter includes a wall 1, a roller shutter assembly 2, a buffer mechanism 3, and a protective mechanism 4. The roller shutter assembly 2 includes a drive housing 201 and a roller shutter door 202, both of which are installed on the inner side of the wall 1. The buffer mechanism 3 includes a buffer shell 301, which is movably installed below the roller shutter door 202. The protective mechanism 4 includes a high-pressure nozzle 402, a sealing plug 406, and a floral diffuser 404. The high-pressure nozzle 402 is fixedly installed on the upper inner part of the wall 1, and the floral diffuser 404 is fixedly installed on the lower part of the high-pressure nozzle 402. The sealing plug 406 is disposed inside the outlet of the high-pressure nozzle 402, and a top rod 407 is fixedly installed on the lower end of the sealing plug 406. Through the protective mechanism 4, the roller shutter assembly 202 is protected against external shocks. Both sides of the upper part of the curtain assembly 2 are equipped with protective mechanisms 4. When a fire occurs inside or outside the roller shutter door 202, the high temperature melts the top rod 407, and the sealing plug 406 is flushed downward by the high-pressure water in the high-pressure nozzle 402. Then, the fire water is sprayed downward through the high-pressure nozzle 402, and at the same time, the fire water is evenly diffused through the flower-shaped diffuser 404. The protective mechanism 4 can be reused. When the protective mechanism 4 needs to be reused, the sealing plug 406 is manually pushed against the water outlet of the high-pressure nozzle 402, and the new top rod 407 is pushed back under the sealing plug 406 by the bolt 408. This realizes automatic water spraying and fire extinguishing in the event of a fire, with uniform water mist diffusion. It can also be manually reset and reused, which improves the fire extinguishing efficiency and the practicality of the device.

[0017] Example 1: Door handles 203 are fixedly installed on both sides of the buffer shell 301. A buffer pad 310 is fixedly installed on the lower surface of the buffer shell 301. A sliding groove 302 is formed on the inner lower surface of the buffer shell 301. A sliding rod 303 is fixedly installed inside the sliding groove 302. Sliding blocks 304 are slidably installed on both sides of the surface of the sliding rod 303. An inner spring 309 is installed on the inner surface of the sliding block 304. An outer spring 308 is installed between the outer surface of the sliding block 304 and the inner wall of the sliding groove 302. Upper rotating seats 306 are fixedly installed on both sides of the lower surface of the roller shutter door 202. A lower rotating seat 305 is fixedly installed on the upper surface of the sliding block 304. A buffer rod 307 is movably installed between the upper rotating seat 306 and the lower rotating seat 305. The upper end of the buffer rod 307 is rotatably mounted on the inner side of the upper rotating seat 306, and the lower end of the buffer rod 307 is rotatably mounted on the inner side of the lower rotating seat 305. Through the buffer mechanism 3, when the roller shutter door 202 is lowered to its limit, the buffer shell 301 first contacts the ground. Then, the buffer shell 301 transmits the pressure it receives to the inner spring 309 through the sliding block 304, causing the inner spring 309 to be compressed and the outer spring 308 to be stretched. Through the restoring elastic force of the inner spring 309 and the outer spring 308, the impact force of the ground on the buffer shell 301 is buffered. At the same time, when the buffer shell 301 slides down to its limit, it contacts and impacts the ground through the buffer pad 310, realizing secondary buffering, reducing equipment wear, extending service life, and improving operational stability and safety.

[0018] Example 2: A strip pipe 401 is fixedly installed on the upper inner part of the wall 1. A high-pressure nozzle 402 is fixedly installed on the lower surface of the strip pipe 401. A flower-shaped diffuser 404 is fixedly installed on the lower surface of the high-pressure nozzle 402 through a connecting rod 403. A threaded hole 405 is opened through the surface of the flower-shaped diffuser 404. A bolt 408 is installed on the inner thread of the threaded hole 405. A top rod 407 is fixedly installed on the upper end of the bolt 408.

[0019] In use, the roller shutter 202 is lowered by the drive housing 201. When the roller shutter 202 descends to near the ground, the buffer mechanism 3 first takes effect. The buffer housing 301 contacts the ground and transmits pressure to the sliding block 304, causing the inner spring 309 to be compressed and the outer spring 308 to be stretched. The initial impact is absorbed by the spring's restoring force. Subsequently, the buffer housing 301 continues to move down to the limit position, and the buffer pad 310 contacts and impacts the ground, achieving secondary buffering, effectively reducing equipment wear and extending service life, and improving operational stability. When a fire occurs inside or outside the roller shutter door 202, the high temperature melts the top rod 407 in the protection mechanism 4. The water pressure in the high-pressure nozzle 402 forces the sealing plug 406 out, and fire-fighting water is sprayed downwards through the high-pressure nozzle 402. At the same time, the flower-shaped diffuser 404 evenly spreads the water flow to form a water mist, covering a larger fire extinguishing area. After the fire is extinguished, the sealing plug 406 can be manually pushed back into the outlet of the high-pressure nozzle 402, and a new top rod 407 can be fixed with bolts 408, realizing the cyclical use of the protection mechanism 4. The entire device, through the synergistic action of the buffer mechanism 3 and the protection mechanism 4, not only ensures the safe and stable descent of the roller shutter door 202, but also automatically activates the fire extinguishing system in case of fire. It has the characteristics of efficient fire extinguishing, uniform diffusion, and reusability, significantly improving the practicality and safety of the device. The top rod 407 is made of Wood alloy, with a melting point typically between 70℃ and 150℃, ensuring timely melting in the early stages of a fire. It also has certain mechanical strength and corrosion resistance, and good processing performance.

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.
