Description

Technical Field

[0001] This utility model relates to the field of fire protection equipment technology, specifically a fire emergency sprinkler device. Background Technology

[0002] Fire emergency sprinkler systems refer to automatic sprinkler systems, also known as "sprinkler systems," which are fixed fire protection facilities widely used in buildings and are mainly used for automatic fire extinguishing in the early stages of a fire.

[0003] Existing sprinkler systems are typically installed on the ceiling of buildings, connected to water pipes installed in the walls. When a fire occurs, heat is transferred to the heat-sensitive glass tubes in the sprinkler system. When the temperature reaches a set value, the heat-sensitive glass tubes break, causing the sprinkler system to spray water for automatic fire suppression.

[0004] Given that existing sprinkler systems only have one fixed spray end face, resulting in a limited spray range, in order to effectively extinguish severe fires or fires with large areas of ignition, it is usually necessary to arrange multiple sprinkler systems on the ceiling surface to spray water over a large area to achieve the purpose of effective fire extinguishing. However, this arrangement undoubtedly leads to problems such as long installation time and complicated layout. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a fire emergency sprinkler device to solve the technical problems of existing sprinkler devices in the background art having only one fixed spray end face, resulting in a limited spray range, which leads to the need to arrange multiple sprinkler devices according to the surface of the ceiling, resulting in long installation time and complicated layout.

[0006] The present invention provides a fire emergency sprinkler device, including a housing for connecting to a water pipe, a turbine drive assembly, a connector, and a transmission pipe having multiple nozzles;

[0007] The turbine drive assembly is rotatably connected inside the housing, the connector is used to rotatably connect the transmission pipe outside the housing, and the turbine drive assembly is used to drive the connector to rotate relative to the housing when the liquid medium is transmitted inside the housing;

[0008] The connector is connected to the housing and the transmission pipe, so that when the connector rotates, the transmission pipe drives multiple nozzles to spray circumferentially along the periphery of the housing.

[0009] Furthermore, the spraying device also includes two brackets that are rotatably connected to each other, one of the brackets being connected to the connector, and the other of the brackets being used to support the transmission pipe.

[0010] Furthermore, the spraying device also includes a linkage component and an annular guide rail with multiple curved sections, the annular guide rail being fixedly connected to the housing;

[0011] The linkage component is used to drively connect a bracket near the transmission pipe to the annular guide rail. When the bracket rotates, the linkage component moves up and down intermittently along multiple curved sections of the annular guide rail, thereby adjusting the spray angle of the multiple nozzles.

[0012] Furthermore, the linkage assembly includes a slider slidably connected to the annular guide rail, and two connecting arms rotatably connected to each other;

[0013] One of the connecting arms is connected to the sliding member, and the other connecting arm is connected to a bracket near the transmission tube.

[0014] Furthermore, the linkage assembly also includes an annular slide rail and a telescopic member slidably connected to the annular slide rail, the annular slide rail being disposed at the bottom of the housing;

[0015] The end of the telescopic member away from the annular slide rail is connected to a connecting lever arm.

[0016] Furthermore, the housing includes an upper shell, a receiving shell, and a lower shell connected in sequence;

[0017] The upper shell is used to communicate with the water pipe, and the lower shell is rotatably connected to the connector.

[0018] Furthermore, the turbine drive assembly includes a turbine, a connecting rod fixedly connected to the turbine, and a connecting disk having at least one hollowed-out area.

[0019] The turbine is rotatably connected inside the housing and connected to one end of the connecting rod, while the other end of the connecting rod passes through the housing and the lower housing and is connected to the connecting disc.

[0020] The outer side of the connecting disc is connected to the inner side of the connector.

[0021] Furthermore, the connecting disk has multiple hollowed-out areas, and these hollowed-out areas are circumferentially spaced with the center of the connecting disk as the origin.

[0022] Furthermore, the spraying device also includes a heat-sensitive glass tube, a valve with a connecting part, and a swing arm;

[0023] The valve is located inside the upper shell, and the connecting part passes through the upper shell and is elastically rotatably connected to one end of the swing arm. The other end of the swing arm is used to abut against the thermosensitive glass tube.

[0024] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0025] The fire emergency sprinkler device of this utility model includes a turbine drive assembly, a connector, and a transmission pipe with multiple nozzles. In the event of a fire, the liquid medium in the water pipe is directly transmitted to the housing. When the liquid medium reaches the housing, it passes through the turbine drive assembly, causing the turbine drive assembly to rotate. The rotation of the turbine drive assembly causes the connector to rotate relative to the housing. This relative rotation of the connector and the transmission pipe drives multiple nozzles to spray circumferentially along the periphery of the housing. The simultaneous spraying of liquid medium from multiple nozzles increases the spraying area, achieving effective fire extinguishing. This solves the problem of needing to arrange multiple sprinkler devices in the prior art, thus reducing installation time and avoiding cumbersome layout. Furthermore, in this application, multiple nozzles can spray circumferentially along the periphery of the housing, further increasing the spraying area and improving the practicality of the sprinkler device in this embodiment.

Detailed Implementation

[0031] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Several embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this utility model will be more thorough and complete.

[0032] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0034] Please see Figures 1 to 4 The image shows a fire emergency sprinkler device according to one embodiment of the present invention, including a housing 100 for communicating with a water pipe, a turbine drive assembly 200, a connector 300, and a transmission pipe 500 having multiple nozzles 400. It should be noted that the water pipe is arranged inside the building wall in the prior art for outputting water source. The water pipe is prior art, so it will not be described in detail here.

[0035] Specifically, the turbine drive assembly 200 is rotatably connected inside the housing 100, the connector 300 is used to rotatably connect the transmission pipe 500 outside the housing 100, and the turbine drive assembly 200 is used to drive the connector 300 to rotate relative to the housing 100 when the liquid medium is transmitted inside the housing 100.

[0036] The connector 300 is connected to the housing 100 and the transmission pipe 500, so that when the connector 300 rotates, the transmission pipe 500 drives multiple nozzles 400 to spray circumferentially along the periphery of the housing 100.

[0037] In practical implementation, when the liquid medium, i.e., water, is transmitted into the housing 100 and passes through the turbine drive assembly 200, the turbine drive assembly 200 can rotate. The rotation of the turbine drive assembly 200 as a whole causes the connector 300 to rotate relative to the housing 100. At this time, the relative rotation of the connector 300 and the transmission pipe 500 drives multiple nozzles 400 to spray circumferentially along the periphery of the housing 100. By using multiple nozzles 400 to spray the liquid medium simultaneously, the spraying range can be increased, achieving the purpose of effective fire extinguishing. This solves the problem of needing to arrange multiple sprinkler devices in the prior art, thereby reducing installation time and avoiding the problem of complicated layout. Furthermore, in this application, multiple nozzles 400 can spray circumferentially along the periphery of the housing 100, further increasing the spraying area of ​​multiple nozzles 400, thereby improving the practicality of the sprinkler device in this embodiment.

[0038] It should be noted that, in this example, the housing 100 includes an upper housing 110, a receiving housing 120 and a lower housing 130 connected in sequence, wherein the upper housing 110 is used to communicate with a water pipe, and the lower housing 130 is rotatably connected to the connector 300.

[0039] The turbine drive assembly 200 includes a turbine 210, a connecting rod 220 fixedly connected to the turbine 210, and a connecting disc 230 having at least one hollowed-out area. The turbine 210 is rotatably connected to the housing 120 and connected to one end of the connecting rod 220. The other end of the connecting rod 220 passes through the housing 120 and the lower housing 130 and is connected to the connecting disc 230. The outer side of the connecting disc 230 is connected to the inner side of the connector 300, and the connecting disc 230 is provided with multiple hollowed-out areas, which are circumferentially spaced with the center of the connecting disc 230 as the origin.

[0040] It should be noted that the turbine 210 is a turbine 210 with multiple helical blades in the prior art. By utilizing the direction of water flow, the turbine 210 can drive the connecting rod 220 to rotate. The interaction between the connecting rod 220 and the connecting disc 230 is used to achieve the purpose of driving the joint 300 to rotate. In order to ensure that the liquid medium can smoothly enter the transmission pipe 500, in this example, multiple hollow areas on the connecting disc 230 are used so that the liquid medium can be input into the transmission pipe 500 through the hollow areas, so as to provide water source for multiple nozzles 400.

[0041] In some preferred embodiments, the spraying device further includes two mutually rotatably connected brackets 600. One of the brackets 600 is connected to the connector 300, and the other bracket 600 is used to support the transmission pipe 500. The brackets 600 can ensure the stability of the transmission pipe 500 during rotation.

[0042] In some other preferred embodiments, the spraying device further includes a linkage component 700 and an annular guide rail 800 having multiple bends, the annular guide rail 800 being fixedly connected to the housing 100 and specifically installed below the lower housing 130.

[0043] The linkage component 700 is used to drive a bracket 600 near the transmission pipe 500 to the annular guide rail 800. When the bracket 600 rotates, the linkage component 700 moves up and down intermittently along multiple curved parts of the annular guide rail 800, thereby adjusting the spray angle of multiple nozzles 400.

[0044] In other words, when the transmission pipe 500 rotates, it will drive the corresponding bracket 600 to rotate. The rotation of the bracket 600 will cause the linkage component 700 to also perform a circular motion. Since the circular guide rail 800 has multiple bends, the linkage component 700 can slide along the bending direction of the multiple bends during the circular motion. At this time, the linkage component 700 will drive the bracket 600 to swing up and down intermittently. Through the swing of the bracket 600, the transmission pipe 500 and multiple nozzles 400 can be driven to swing up and down, which means that the spraying angle of the multiple nozzles 400 is adjusted, thereby ensuring that the multiple nozzles 400 can effectively spray at multiple positions in the circumference, and further improve the spraying range.

[0045] It should be noted that in this example, the linkage component 700 includes a slider 710 slidably connected to the annular guide rail 800, and two connecting arms 720 rotatably connected to each other. One connecting arm 720 is connected to the slider 710, and the other connecting arm 720 is connected to a bracket 600 near the transmission tube 500.

[0046] To further ensure the stability of the transmission tube 500 during its up-and-down swing, in some optional embodiments, the linkage assembly 700 also includes an annular slide rail 730 and a telescopic member 740 slidably connected to the annular slide rail 730. The annular slide rail 730 is located at the bottom of the housing 100. The end of the telescopic member 740 away from the annular slide rail 730 is connected to a connecting arm 720. Specifically, the annular slide rail 730 is installed at the bottom of the lower housing 130, and the cross-section of the annular slide rail 730 is annular.

[0047] In addition, the spray device in this example also includes a thermosensitive glass tube 900, a valve 910 with a connecting part 911, and a swing arm 920. The valve 910 is located inside the upper shell 110, and the connecting part 911 passes through the upper shell 110 and is elastically rotatably connected to one end of the swing arm 920. The other end of the swing arm 920 is used to abut against the thermosensitive glass tube 900.

[0048] Specifically, the connecting part 911 can be rotatably connected to one end of the swing arm 920 by a torsion spring in the prior art. When the thermosensitive glass tube 900 is affected by high temperature, it will break. The swing arm 920 will swing due to the rotational elasticity. At this time, the valve 910 will open, and the water source in the water pipe will be input into the interior of the upper shell 110 to achieve the purpose of water supply.

[0049] It should be noted that the thermistor glass tube 900 is a conventional prior art in this field and will not be specifically described here.

[0050] In summary, the fire emergency sprinkler device according to one embodiment of this utility model has at least the following beneficial effects compared to existing sprinkler devices:

[0051] The fire emergency sprinkler device of this utility model includes a turbine drive assembly 200, a connector 300, and a transmission pipe 500 with multiple nozzles 400. In the event of a fire, the liquid medium in the pipe is directly transmitted to the housing 100. When the liquid medium reaches the housing 100, it passes through the turbine drive assembly 200, causing the turbine drive assembly 200 to rotate. This rotation of the turbine drive assembly 200 causes the connector 300 to rotate relative to the housing 100. At this time, the connector 300 and the transmission pipe 500... The relative rotation of the nozzles causes multiple nozzles 400 to spray circumferentially along the periphery of the housing 100. By simultaneously spraying liquid media from multiple nozzles 400, the spraying range can be increased, achieving the purpose of effective fire extinguishing. This solves the problem of needing to arrange multiple sprinkler devices in the prior art, thereby reducing installation time and avoiding the problem of complicated layout. Furthermore, in this application, multiple nozzles 400 can spray circumferentially along the periphery of the housing 100, further increasing the spraying area of ​​multiple nozzles 400 and improving the practicality of the sprinkler device in this embodiment.
