Description

Technical Field

[0001] This utility model relates to the field of building exterior wall fire protection technology, specifically an automatic sprinkler fire extinguishing device for building exterior walls. Background Technology

[0002] Automatic sprinkler systems on building exterior walls are automatic sprinkler systems installed on the exterior walls of buildings. They are mainly used to protect the exterior walls of buildings and their surrounding areas. These systems typically include components such as sprinklers, pipes, and alarm valve assemblies. They can automatically activate when a fire occurs and control and extinguish the fire by spraying water.

[0003] Existing automatic sprinkler systems for building exteriors suffer from dust and impurities accumulating at the nozzles due to the fact that most sprinkler heads are installed on the exterior walls for extended periods and exposed to the external environment. This blockage can reduce water flow and hinder timely fire suppression, resulting in a poorer fire extinguishing effect. Therefore, we propose an automatic sprinkler system for building exteriors to address these issues. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic sprinkler fire extinguishing device for building exterior walls, in order to solve the problem that since most sprinkler heads are installed on the exterior walls of buildings for a long time and are in the external environment, dust and impurities from the external environment tend to accumulate at the nozzles of the sprinkler heads. When the fire is needed, the water output may be reduced due to the blockage of the sprinkler heads, thus failing to extinguish the fire in time and resulting in a poor fire extinguishing effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An automatic sprinkler fire extinguishing device for building exterior walls includes a building exterior wall body and an installation groove. The installation groove is located on the inner side of the building exterior wall body. A water pipe is installed inside the installation groove. A flexible telescopic hose is fixedly connected to the right end of the water pipe. A connecting plate is fixedly connected to the right end of the flexible telescopic hose. Electric telescopic rods are fixedly connected to the upper and lower parts of the left end of the connecting plate. Limit blocks are fixedly connected to both the upper and lower ends of the connecting plate. A placement groove is located on the right end of the building exterior wall body. Limit grooves are provided at both the upper and lower ends of the placement groove. A nozzle is fixedly connected to the right end of the connecting plate. A pressure valve is provided at the front end of the nozzle. A mounting base is fixedly connected to the right end of the building exterior wall body. A rubber pad is fixedly connected to the inner side of the mounting base. A retaining plate is provided inside the rubber pad. A baffle is fixedly connected to the upper end of the retaining plate. A limit plate is fixedly connected to the inner side of the baffle. A smoke detector is installed on the right end face of the building exterior wall body.

[0007] Preferably, the mounting groove is located on the left side of the placement groove and is interconnected with it; the left end of the elastic telescopic hose is fixedly connected to the left end of the placement groove; the connecting plate is located inside the placement groove; and the water pipe, the elastic telescopic hose, and the nozzle are interconnected.

[0008] Preferably, the left end of the electric telescopic rod and the left end of the placement groove are fixedly connected, the electric telescopic rod is located on the upper and lower sides of the elastic telescopic hose, and the outer side of the limiting block and the inner side of the limiting groove are slidably connected.

[0009] Preferably, the nozzle and the pressure valve are both located inside the placement slot, the card holder is located on the upper right side of the placement slot, and the lower end of the card plate passes through the card holder.

[0010] Preferably, the inner upper side of the baffle is fitted to the upper end of the card seat, the baffle is in the shape of an inverted "L", the limiting plate is located on the right side of the nozzle, and the smoke detector, pressure valve, electric telescopic rod and controller are electrically connected.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In this invention, by setting up an elastic telescopic hose, a connecting plate, an electric telescopic rod, a placement groove, a mounting base, a clamping plate, and a baffle, when the nozzle is not in use, activating the electric telescopic rod causes the connecting plate and the nozzle as a whole to move inward, allowing the nozzle to enter the placement groove. This reduces the nozzle's exposure to the outside environment, preventing dust and impurities from accumulating at the nozzle's spray nozzle. It also prevents corrosion from rainwater and direct sunlight, extending the nozzle's service life. The baffle, secured to the mounting base by the clamping plate, blocks the placement groove, reducing the entry of dust and impurities. This effectively reduces dust and impurity accumulation that can clog the nozzle, ensuring smooth water spray during use and enabling timely fire extinguishing for better fire suppression.

[0022] Please see Figure 1-7 This utility model provides a technical solution:

[0023] An automatic sprinkler fire extinguishing device for building exterior walls includes a building exterior wall body 1 and an installation groove 2. The installation groove 2 is provided on the inner side of the building exterior wall body 1. A water pipe 3 is installed inside the installation groove 2.

A smoke detector 17 is installed on the right end face of the building exterior wall body 1.

[0024] The mounting slot 2 is located on the left side of the placement slot 8 and is interconnected with it. The left end of the flexible telescopic hose 4 is fixedly connected to the left end of the placement slot 8. The connecting plate 5 is located inside the placement slot 8. The water pipe 3, the flexible telescopic hose 4, and the nozzle 10 are interconnected. The left end of the electric telescopic rod 6 is fixedly connected to the left end of the placement slot 8. The electric telescopic rod 6 is located on the upper and lower sides of the flexible telescopic hose 4. The outer side of the limiting block 7 and the inner side of the limiting slot 9 are slidably connected. The nozzle 10 and the pressure valve 11 are both located inside the placement slot 8. The card seat 12 is located on the upper right side of the placement slot 8. The lower end of the card plate 14 passes through the card seat 12. The inner side of the upper end of the baffle 15 is attached to the upper end of the card seat 12. The nozzle is shaped like an inverted "L". The limiting plate 16 is located on the right side of the nozzle 10. The smoke detector 17, pressure valve 11, electric telescopic rod 6, and controller are electrically connected. An installation groove 2 is provided on the inner side of the building exterior wall 1. A water pipe 3 is installed inside the installation groove 2. An elastic telescopic hose 4 is fixedly connected to the right end of the water pipe 3, which facilitates the installation of the elastic telescopic hose 4, connecting plate 5, electric telescopic rod 6, placement groove 8, bracket 12, clamping plate 14, and baffle 15. When the nozzle 10 is not in use, the electric telescopic rod 6 is activated. The electric telescopic rod 6 drives the connecting plate 5 and the nozzle 10 to move inward as a whole, so that the nozzle 10 enters the placement groove. Inside the placement groove 8, the nozzle 10 is kept away from the outside environment, which would prevent dust and impurities from accumulating at the nozzle. This also prevents corrosion from rain and direct sunlight, extending the nozzle's lifespan. The baffle 15 is secured to the mounting base 12 via the clamping plate 14, thus shielding the placement groove 8 and reducing the entry of dust and impurities. This effectively reduces dust and impurity buildup that could clog the nozzle, ensuring smooth water flow and timely fire extinguishing for better results. A connecting plate 5 is fixedly connected to the right end of the flexible telescopic hose 4, with the left end of the connecting plate 5... Both parts are fixedly connected to an electric telescopic rod 6. Limiting blocks 7 are fixedly connected to both the upper and lower ends of the connecting plate 5. A placement groove 8 is opened at the right end of the building exterior wall body 1. Limiting grooves 9 are opened at both the upper and lower ends of the placement groove 8. A nozzle 10 is fixedly connected to the right end of the connecting plate 5. A pressure valve 11 is provided at the front end of the nozzle 10. A card seat 12 is fixedly connected to the right end of the building exterior wall body 1. A rubber pad 13 is fixedly connected to the inside of the card seat 12. A card plate 14 is provided inside the rubber pad 13. A baffle 15 is fixedly connected to the upper end of the card plate 14. A limiting plate 16 is fixedly connected to the inside of the baffle 15. A smoke detector 17 is installed on the right end face of the building exterior wall body 1.

[0025] Workflow: The device is powered by an external power source during use. In the event of a fire, the smoke detector 17 detects smoke and then activates the water pump, electric telescopic rod 6, and pressure valve 11 via an external controller. The water pump is connected to one end of the water pipe 3, allowing water from the storage tank to enter the water pipe 3. The electric telescopic rod 6 then moves the connecting plate 5 and the nozzle 10 to the right. The connecting plate 5 moves the limiting block 7 along the limiting groove 9, which limits the limiting block 7, making the overall movement of the connecting plate 5 and the nozzle 10 more stable. When the nozzle 10 moves out of the placement groove 8, the limiting plate 16 limits the nozzle 10, and then the nozzle 10 stops moving. At this time, the water from the water pipe 3 enters the elastic telescopic hose 4 and is finally sprayed out quickly from the nozzle 10 to extinguish the fire promptly. After the nozzle 10 is used, the electric telescopic rod 6 is activated, moving the connecting plate 5 and the nozzle 10 to the left, allowing the nozzle 10 to retract into the placement groove 8. Reducing the exposure of the nozzle 10 to the outside environment prevents dust and impurities from accumulating at the nozzle's spray outlet. It also prevents corrosion from rain and direct sunlight, extending the nozzle's lifespan. The baffle 15 is secured to the mounting base 12 via the clamping plate 14. The rubber pad 13 increases the friction between the mounting base 12 and the clamping plate 14, improving the engagement. The baffle 15 then shields the placement slot 8, reducing the entry of dust and impurities and effectively preventing nozzle 10 blockage. This ensures smooth water spray during subsequent use, allowing for timely fire extinguishing and improved firefighting effectiveness. The baffle 15 also protects the internal components of the placement slot 8 from damage caused by accidental impacts. If the baffle 15 is damaged by an accidental impact, simply pull it upwards to remove the clamping plate 14 from the rubber pad 13, and then remove it. The process can be repeated in reverse for replacement. This replacement operation is simple and convenient.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
