Description

Technical Field

[0001] This invention relates to the field of fire protection equipment technology, specifically to a multi-angle cooling spray device for fire extinguishing. Background Technology

[0002] A fire sprinkler system is a widely used fixed fire-fighting facility characterized by its low cost and high extinguishing efficiency. Depending on its function, it can be divided into two types: manual control and automatic control. Systems equipped with alarm devices can automatically sound an alarm in the event of a fire. Automatically controlled fire sprinkler systems can also automatically spray water and work in sync with other fire-fighting facilities, thus effectively controlling and extinguishing initial fires.

[0003] However, existing fire sprinkler systems cannot effectively identify the location of the fire. When a fire breaks out, the fire sprinkler system can only extinguish the fire by spraying over a large area. This method not only wastes a lot of water resources, but the spraying of the extra nozzles will also cause unnecessary damage to other items. Furthermore, when the fire sprinkler system sprays on a large scale, the extra nozzles will divert some of the water pressure, resulting in lower water pressure near the fire point, which cannot effectively extinguish the fire and thus causes the fire to spread rapidly, resulting in property damage to users.

[0004] Therefore, it is necessary to provide a fire-fighting and fire-extinguishing multi-angle cooling spray device to solve the above problems. Summary of the Invention

[0005] To achieve the above objectives, the present invention provides the following technical solution: a multi-angle cooling spray device for fire extinguishing, comprising:

[0006] The device base plate has multiple sets of water storage tanks fixedly mounted on it. The left side of each water storage tank is connected to a water inlet pipe, and the water inlet pipe is connected to a water supply device. The right side of each water storage tank is connected to the input port of a water pump, and the output port of the water pump is fixedly mounted with a water supply pipe.

[0007] A water supply network is fixedly connected horizontally to the right side of the water supply pipe. Multiple sets of water spray interfaces are fixedly connected to the water supply network, and a spray assembly is fixedly installed at the lower end of each set of water spray interfaces.

[0008] The control system is fixedly mounted on the upper surface of the device base plate.

[0009] Furthermore, preferably, the spray assembly includes:

A water flow pipe is provided above the water flow chamber. The water flow pipe is embedded inside the fixing block and connected to the water spray interface.

[0011] The main switch valve is fixedly mounted directly below the water flow chamber. A fire source determination component is coaxially fixedly mounted below the main switch valve, and a fixing shell is fitted on the outside of the fire source determination component.

[0012] Furthermore, as a preferred embodiment, eight sets of fire extinguishing and cooling components are arranged on the circumference of the side of the fixed shell, and the upper end of the fire extinguishing and cooling components is fixedly connected to the water diversion chamber.

[0013] Furthermore, as a preferred embodiment, a temperature sensor and an alarm are fixedly mounted on the lower surface of the fixed housing.

[0015] The fire source determining shell is coaxially fixedly assembled at the lower end of the main switch valve, with a water outlet block fixedly assembled in its middle part, and a positive water spray pipe slidably embedded at the lower end of the fire source determining shell.

[0016] The water distribution plate is coaxially fixedly assembled at the lower end of the fire source determining shell.

[0017] Furthermore, as a preferred embodiment, the area between the fire source determining shell and the water outlet block is a water passage chamber, and the area between the positive spray pipe and the water outlet block is a regulating chamber. The water passage chamber and the regulating chamber are connected by multiple sets of water inlets opened on the water passage block.

[0018] Furthermore, as a preferred embodiment, an adjusting ring is provided at the connection between the positive water spray pipe and the fire source determining shell, and the adjusting ring is filled with water-expanding material.

[0019] Furthermore, as a preferred embodiment, the lower end of the water distribution plate is fitted with multiple sets of micro nozzles, and each set of micro nozzles has a different spray direction.

[0020] Furthermore, preferably, the fire extinguishing and cooling component includes:

[0021] The auxiliary switch valve is fixedly mounted on the side of the water flow chamber, and a connecting pipe is fixedly mounted on the other end of the valve.

[0023] Compared with the prior art, the present invention provides a multi-angle cooling spray device for fire extinguishing, which has the following beneficial effects:

[0024] In this invention, a control system is provided to directly control the sprinkler assembly and the water pump. When a fire occurs, the fire information is transmitted to the control system, which then controls the water pump and the sprinkler assembly to activate. The sprinkler assembly is equipped with a fire source determination component and a fire extinguishing and cooling component. After the fire source determination component is activated, it sprays a certain amount of water mist downwards and determines the location of the fire point based on the feedback after the water spraying. This location is then transmitted to the control system, which controls the fire extinguishing and cooling components of the sprinkler assembly near the fire point to adjust to a suitable angle to extinguish and cool the fire point, achieving precise targeting of the fire point. This saves water resources while protecting user property and significantly improves the efficiency of fire suppression. Furthermore, the fire source determination component determines the location of the fire point by spraying water mist, avoiding the waste of water resources and additional damage to property caused by direct water spraying.

[0030] Please see Figures 1-4 This invention provides a multi-angle cooling spray device for fire extinguishing, comprising:

[0031] The device base plate 1 has multiple sets of water storage tanks 2 fixedly mounted on it. The left side of the water storage tank 2 is connected to a water inlet pipe 3, and the water inlet pipe 3 is connected to a water supply device. The right side of the water storage tank 2 is connected to the input port of a water pump 4, and the output port of the water pump 4 is fixedly mounted with a water pipe 5.

[0032] A water supply network 6 is fixedly connected horizontally to the right side of the water supply pipe 5. Multiple sets of water spray interfaces 7 are fixedly connected to the water supply network 6. A spray assembly 8 is fixedly installed at the lower end of each set of water spray interfaces 7.

[0033] The control system 9 is fixedly mounted on the upper surface of the device base plate 1;

[0034] In a preferred embodiment, the control system 9 directly controls the sprinkler assembly 8 and the water pump 4. When a fire occurs, the fire information is transmitted to the control system 9, which then controls the water pump 4 and the sprinkler assembly 8 to start. After the sprinkler assembly 8 starts, it sprays a certain amount of water mist downwards and determines the location of the fire point based on the feedback results after spraying the water mist. This location is then transmitted to the control system 9, which controls the sprinkler assembly 8 near the fire point to adjust to a suitable angle to extinguish and cool the fire point. This achieves precise targeting of the fire point, protecting user property while conserving water resources and significantly improving the efficiency of fire suppression.

[0035] Furthermore, the spray assembly 8 includes:

[0036] A fixing block 81 is fixedly installed directly below the water spray interface 7. A water flow chamber 83 is fixedly installed at its lower end. A water flow pipe 82 is provided above the water flow chamber 83. The water flow pipe 82 is embedded inside the fixing block 81 and connected to the water spray interface 7.

[0037] The main switch valve 84 is fixedly mounted directly below the water flow chamber 83. A fire source determination component 85 is coaxially fixedly mounted below the main switch valve 84. A fixing shell 87 is fitted on the outside of the fire source determination component 85.

[0038] Furthermore, eight sets of fire extinguishing and cooling components 86 are arranged on the circumference of the side of the fixed shell 87, and the upper end of the fire extinguishing and cooling components 86 is fixedly connected to the water diversion chamber 83.

[0039] In a preferred embodiment, each of the eight fire extinguishing and cooling components 86 corresponds to an adjacent spray component 8, which facilitates targeted extinguishing of the fire point later.

[0040] Furthermore, a temperature sensor 88 and an alarm 89 are fixedly mounted on the lower surface of the fixed housing 87;

[0041] In the preferred embodiment, when a fire occurs, the temperature sensor 88 near the ignition point will rapidly heat up and transmit the information to the control system 9, simultaneously activating the alarm 89. The control system 9 will activate the water pump 4 and the main switch valve 84 of the sprinkler assembly 8 that triggered the alarm will cause water to flow through the fire source detection component 85 and spray it into the area where the sprinkler assembly 8 is located. Based on the feedback from the fire source detection component 85, the control system 9 will determine the approximate location of the ignition point. Based on the feedback from the fire source detection component 85, the control system 9 will activate the fire extinguishing and cooling component 86 near the ignition point and control the fire extinguishing and cooling component 86 to adjust to a suitable angle to accurately strike the location of the fire.

[0042] Furthermore, the fire source determination component 85 includes:

[0043] A fire source determining shell 851 is coaxially fixedly mounted at the lower end of the main switch valve 84, and a water outlet block 852 is fixedly mounted in the middle. A positive water spray pipe 853 is slidably embedded at the lower end of the fire source determining shell 851.

[0044] The water distribution plate 854 is coaxially fixedly assembled at the lower end of the fire source determining shell 851.

[0045] Furthermore, the area between the fire source determining shell 851 and the water outlet block 852 is the water passage chamber 855, and the area between the positive water spray pipe 853 and the water outlet block 852 is the regulating chamber 856. The water passage chamber 855 and the regulating chamber 856 are connected by multiple sets of water inlets 857 opened on the water passage block.

[0046] Furthermore, an adjusting ring 858 is provided at the connection between the positive water spray pipe 853 and the fire source determining shell 851, and the adjusting ring 858 is filled with water-expanding material;

[0047] In a preferred embodiment, when the main switch valve 84 is opened, water flows from the water distribution chamber 83 into the water passage chamber 855, and then flows into the regulating chamber 856 through the inlet 857. Subsequently, it falls into the water distribution plate 854 through the gap between the main spray pipe 853 and the outlet block 852. Multiple sets of micro-nozzles 859 embedded in the water distribution plate 854 activate upon contact with water, spraying water in the form of a mist onto various areas of the spray assembly 8. When a fire point is located within this area, the sprayed water mist encounters the fire point. If the fire point is small, it is extinguished directly, thus lowering the indoor temperature. Furthermore, the sprayed water mist will not cause unnecessary damage to other items in the room. As the temperature decreases, the temperature sensor 88 returns to its normal state. The control system 9 controls the shutdown of each spray assembly 8 and the water pump 4. If the fire is large and not extinguished directly, it will generate a large amount of water vapor. The rising water vapor will be absorbed by the regulating ring 858 near the fire point. The water-expanding material filled in the regulating ring 858 absorbs water and expands, driving the main spray pipe 853 to rise and blocking the gap between it and the water outlet block 852. The water level in the regulating chamber 856 rises rapidly. When the water level rises to be level with the top of the main spray pipe 853, water is sprayed out from the main spray pipe 853. The main spray pipe 853 will quickly cover the area and deal with the fire point until the fire point is extinguished. If the fire point is not in the area, the main switch valve 84 of the area will be closed after the micro nozzle 859 sprays a certain amount of water mist.

[0048] Furthermore, the lower end of the water distribution plate 854 is fitted with multiple sets of micro nozzles 859, and each set of micro nozzles 859 sprays in a different direction, so that the water mist sprayed by the micro nozzles 859 can cover the area where the spray assembly 8 is located, which facilitates the determination of the ignition point.

[0049] Furthermore, the fire extinguishing and cooling component 86 includes:

[0050] The auxiliary switch valve 861 is fixedly mounted on the side of the water flow chamber 83, and a connecting pipe 862 is fixedly mounted on the other end of the valve. A rotating interface 863 is fixedly mounted on the other end of the connecting pipe 862. The rotating interface 863 is rotatably mounted on the outer side of the fixed shell 87, and a side spray head 864 is fixedly mounted on the other end of the rotating interface 863.

[0051] Furthermore, a gear 867 is coaxially fixed on the outer side of the rotating interface 863 near the fixed housing 87. The gear 867 meshes with a transmission gear 866. The transmission gear 866 is coaxially fixed on the output shaft of the micro motor 865. The micro motor 865 is fixedly mounted on the fixed housing 87.

[0052] In a preferred embodiment, after the fire source determination component 85 determines the ignition point, the control system 9 controls the secondary switch valve 861 of the corresponding fire extinguishing and cooling component 86 of 3-8 groups of spray components 8 near the ignition point (the minimum number of spray components 8 that can be supported is 3 when the area where the ignition point is located is in a corner of this sprinkler system, and the maximum number of spray components 8 that can be supported is 8 when the area where the ignition point is located is in the middle of this sprinkler system). Water in the water diversion chamber 83 is sprayed to the area where the ignition point is located through the side spray head 864 via the connecting pipe 862 after the secondary switch valve 861 is opened. At the same time, during the opening of the secondary switch valve 861, the control system 9 activates the corresponding micro motor 865, which, through the transmission of gear 867 and transmission gear 866, adaptively adjusts the position of the rotating interface 863 and the side spray head 864 so that the side spray head 864 points to the location of the ignition point, thereby improving the fire extinguishing efficiency.

[0053] In practice, the following steps are included: When a fire occurs, the temperature sensor 88 near the ignition point will rapidly heat up and transmit the information to the control system 9. At the same time, the alarm 89 will be activated. The control system 9 will activate the water pump 4 and the main switch valve 84 of the sprinkler assembly 8 that triggered the alarm will be activated. The water flow will spray water mist through the micro nozzles 859 on the fire source determination component 85 to the area where the sprinkler assembly 8 is located. Based on the feedback results, the approximate location of the ignition point will be determined. The control system 9 will mobilize the fire extinguishing and cooling component 86 near the ignition point based on the feedback results of the fire source determination component 85, and control the fire extinguishing and cooling component 86 to adjust to a suitable angle to accurately strike the location of the fire. This will save water resources while protecting the user's property and greatly improve the efficiency of fire extinguishing.

[0054] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
