Description

Technical Field

[0001] The present application relates to the technical field of fire protection, and specifically discloses an indoor automatic fire extinguishing device. Background Art

[0002] Fire extinguishers and indoor fire extinguishing devices are one of the necessary fire-fighting equipment. They are often stored and installed in buildings and indoors. When a fire occurs in a building or indoors, fire extinguishers and indoor fire extinguishing devices are needed to complete the fire-fighting work.

[0003] In the prior art, fire extinguishing devices are mainly divided into passive fire extinguishing devices and automatic fire extinguishing devices. Passive fire extinguishing devices are common fire extinguishers, fire hydrants and various types of fire extinguishing equipment used in fire alarms. They are fire extinguishing devices that require manual control and manual use. Such devices are suitable for low-rise buildings and floors, and humans can reach the fire scene within a certain period of time to use these fire extinguishing devices.

[0004] However, for some super-high floors or higher floors, it is difficult to reach them within the appropriate time by manpower, and it is difficult to effectively control the fire within the golden time of fire extinguishing. At this time, it is necessary to rely on or be able to install automatic fire extinguishing equipment.

[0005] The automatic fire extinguishing device mainly consists of two parts: a high-pressure nozzle fixedly installed on the indoor roof and a water supply pipeline laid indoors and connected to the high-pressure nozzle. The high-pressure nozzle is equipped with an electromagnetic valve to control the flow and spraying of high-pressure water in the water supply pipeline. The high-pressure nozzle is installed at one point and the direction of high-pressure water spraying is controlled by a steering device.

[0006] Although the existing indoor automatic fire extinguishing device can detect the fire in time and effectively control the fire through high-pressure water, it can only rotate in place. When spraying at a place far away from itself, the force of the high-pressure water spray will gradually decrease, and there is a blind spot for the fire below itself, resulting in incomplete fire extinguishing and the risk of re-ignition.

[0007] Therefore, in view of this, the inventor provides an indoor automatic fire extinguishing device to solve the above problems. Summary of the invention

[0008] The purpose of the present invention is to solve the problem that the traditional indoor automatic fire extinguishing device can only rotate and spray water in place, cannot effectively control the fire far away from itself and in the blind spot, and the fire is not completely extinguished, which is prone to re-ignition.

[0009] In order to achieve the above-mentioned object, the basic scheme of the present invention provides an indoor automatic fire extinguishing device, including walking rails respectively arranged between the top ends of adjacent two side walls, liquid inlet boxes respectively arranged at one end of the walking rails, and sprinkler assemblies respectively slidably connected to the walking rails and used for spraying water;

[0010] A fire-fighting water pipe is provided in the liquid inlet box, and a central control machine for receiving, calculating and transmitting data is also provided in the liquid inlet box. A detection unit is provided at the top of the liquid inlet box, which is electrically connected to the central control machine and is used to detect the indoor environment. The fire-fighting water pipe is also connected to a solenoid valve electrically connected to the central control machine.

[0011] The sprinkler assembly includes an electric slider slidably connected to the travel guide rail and controlled by the central control machine, a travel bracket fixedly connected to the electric slider, and a fire fighting unit arranged in the travel bracket;

[0012] The fire fighting unit includes a driving column, a turntable rotatably connected to the driving column and connected to a fire fighting water pipe, and a driving structure arranged in the driving column and controlled by a central control machine and used to drive the turntable to rotate. The turntable is provided with a pipeline for discharging water and connected to the fire fighting water pipe.

[0013] Furthermore, the walking guide rail includes straight sections respectively arranged on two adjacent side walls and a transition section arranged between the straight sections on both sides, and the liquid inlet tank is arranged at the end of one side of the straight section.

[0014] Furthermore, both ends of the driving column are detachably connected with a rotating shaft, the rotating shaft is rotatably connected in the traveling bracket, and a first driving motor controlled by the central control machine and used for driving the rotating shaft to rotate is provided in the traveling bracket.

[0015] Furthermore, a water distribution chamber is provided in the turntable, a water inlet pipe connected to the water distribution chamber is provided on one side of the turntable, and a water outlet pipe connected to the water distribution chamber is provided on the other side of the turntable. The water inlet pipe is connected to the fire water pipe, and a position sensor connected to the central control motor is also provided on the turntable.

[0016] Furthermore, the driving structure includes a third driving motor arranged in the driving column and a rotating shaft coaxially connected to the output shaft of the third driving motor. A rotating hole is provided on one side of the turntable, and an axial hole coaxially connected to the transmission shaft is provided in the rotating hole.

[0017] Furthermore, a plurality of latch teeth are circumferentially arranged on the rotating disk between the shaft hole and the rotating hole, a dial is coaxially connected to the rotating shaft, and a plurality of protrusions which can respectively engage between the latch teeth are circumferentially arranged on one side of the dial facing the rotating disk.

[0018] Furthermore, a spray station is provided on the side of the turntable facing the water outlet pipeline. The water outlet pipeline extends to the end face of the spray station and passes through the spray station. A turntable is also rotatably connected to the end face of the spray station. A second motor for driving the turntable to rotate is provided in the spray station. A plurality of spray holes for controlling the sprayed water flow are provided circumferentially on the turntable.

[0019] Furthermore, the spray hole includes a converging spray head whose inner diameter gradually decreases in the direction away from the water outlet pipe and a diffusing spray head whose inner diameter gradually increases in the direction away from the water outlet pipe.

[0020] Furthermore, the spray hole also includes a separation nozzle provided with a partition to increase the number of water columns and a water mist nozzle with a honeycomb baffle at the end.

[0021] Furthermore, it includes a central control unit for receiving, transporting and transmitting data, a detection unit for detecting the indoor field environment, a fire fighting unit for supplying and spraying water, a driving unit for controlling the spraying direction of the fire fighting unit, a walking unit for controlling the movement of the fire fighting unit and a water supply unit for controlling the water supply of the fire fighting unit.

[0022] The principle and effect of this scheme are:

[0023] 1. The present invention realizes the detection function of the on-site environment through the detection unit, and transmits the detected information to the central control unit. After receiving the real-time data transmitted by the detection unit, the central control unit judges the on-site environment by storing and analyzing the received data and the captured video. If there is no fire, the fire fighting unit is not activated. If a fire is found, the fire fighting unit is activated.

[0024] 2. After the fire is discovered, the present invention first controls the walking unit to move, cooperates with the position sensor carried on the turntable, and receives data from the position sensor and the detection unit through the central control machine to move the fire-fighting unit to the opposite place where the fire exists. Then, the driving unit is used to accurately adjust the direction of the water outlet pipe on the turntable to accurately align it with the fire. The first driving motor is used to control the rotation of the rotating shaft to drive the fire-fighting unit to rotate along the Z axis as a whole. The third driving motor is used to control the vertical rotation of the turntable and the plane to complete 360° free angle selection. Then, the solenoid valve is opened to complete the connection of the fire-fighting water pipe, and the fire-fighting fire alarm is extinguished without blind spots.

[0025] 3. The present invention can regulate the sprayed high-pressure water through the spray holes on the rotary disk mounted on the spray station, wherein the inner diameter of the converging nozzle is smaller than the inner diameter of the water outlet pipe, and can gather the water pressure and water flow when the high-pressure water flows through the converging nozzle, thereby increasing the spraying distance and the pressure of the sprayed water flow; the inner diameter of the diffusing nozzle is larger than the inner diameter of the water outlet pipe, and can diffuse the water pressure and water flow when the high-pressure water flows through the diffusing nozzle, although it will shorten the spraying distance, it can expand the spraying area.

[0026] 4. The other two groups of spray holes provided by the present invention have the following effects: the inner diameter of the separation nozzle is equal to the inner diameter of the water outlet pipe, and when the high-pressure water flows through the separation nozzle, it can separate a high-pressure water flow into multiple parallel high-pressure water flows, divert the water flow, and increase the spraying area after the water flow is sprayed out; the water mist nozzle is provided with a baffle, and a plurality of honeycomb holes are opened on the baffle. After the high-pressure water hits the baffle, it will spray out through the honeycomb holes, and the impact will generate water mist. While generating the water flow, it cooperates with the water mist to control the indoor fire and complete the fire extinguishing work. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0036] An indoor automatic fire extinguishing device, for example Figure 1 As shown:

[0037] It comprises two groups of walking rails 6 respectively installed at the top of the indoor wall 1, a liquid inlet box 2 respectively installed at one side of the walking rails 6, and a nozzle assembly respectively installed on the walking rails 6 and movable on the walking rails 6.

[0038] The running rail 6 includes a straight section and a transition section. Each set of running rails 6 includes two straight sections and a transition section, the two straight sections are respectively installed on the top of the wall 1 on both sides of the room, and the transition section is installed between the two straight sections for the transition between the two straight sections of the nozzle.

[0039] In this embodiment, the straight section and the transition section are each provided with two mutually connected receiving grooves and a moving groove. The receiving groove is provided on the inner side of the straight section and the transition section, the receiving groove is a continuous cylindrical groove body, and both ends of the receiving groove respectively penetrate the end of the straight section. The moving groove is provided on the top of the straight section and the transition section, the moving groove is a continuous rectangular groove body, and both ends of the moving groove do not penetrate the end of the straight section.

[0040] The liquid inlet box 2 is installed at the end of a straight section of each group of walking guide rails 6, and at the same time closes the end of the straight section of another group of walking guide rails 6. A networked central control machine is installed in each of the liquid inlet boxes 2. The central control machine serves as a control center and is responsible for data reception, data processing and data transmission functions. In this embodiment, the data processing core of the central control machine is a single-chip microcomputer. In the liquid inlet box 2, a cavity for accommodating a fire water pipe is also provided. In this embodiment, the fire water pipe adopts a bellows 9 plus a connecting water pipe, and the bellows 9 is connected to the end of the connecting water pipe. The bellows 9 has good stretching performance and can perform operations such as steering. The fire water pipe is stored in the cavity, and a through hole connected to the receiving groove is provided on the side of the liquid inlet box 2 facing the connected walking guide rail 6. The bellows 9 of the fire water pipe passes through the through hole and is placed in the receiving groove. The bottom end of the fire hose extends to the fire hydrant in the room and is connected to the fire hydrant, wherein the fire hydrant is always in a normally open state, and connected to the fire hydrant is a connecting water pipe, which extends into the cavity and is connected to a solenoid valve for controlling the connection between the connecting water pipe and the bellows 9. The solenoid valve is connected to the central control machine and is controlled to open and close by the central control machine.

[0041] At the top of the liquid inlet box 2, a detection unit electrically connected to the central control machine is also installed, and the detection unit includes two parts: a temperature detection module and a field detection module. The detection unit is installed on a rotating bracket with a rotating function. In this embodiment, the temperature detection module is a temperature sensor 3, which is installed on the top of the rotating bracket. The field detection module includes an infrared camera 4 and an Internet camera 5 respectively installed on both sides of the rotating bracket. The temperature sensor 3, the infrared camera 4 and the Internet camera 5 are all electrically connected to the central control machine, and each uploads the detection data and the video footage taken to the central control machine, which stores and analyzes the data and the video footage taken, and determines whether a fire has occurred and whether the nozzle assembly needs to be used.

[0042] like Figure 4 As shown, the sprinkler assembly includes an electric slider installed in a moving groove, a traveling bracket installed on the inner side of the walking guide rail 6 and driven by the electric slider, and a fire fighting unit installed on the traveling bracket.

[0043] The electric slider is installed in the moving groove at the top of the walking rail 6, and can move back and forth in the moving groove repeatedly, and is controlled by the central control machine. The traveling bracket includes a connecting plate 7 installed at the top of the electric slider, a vertical rod integrally formed on the inner side of the connecting plate 7 and located on the inner side of the walking rail 6, and two mutually parallel horizontal rods integrally formed on the inner side of the vertical rods. The fire unit is installed between the two horizontal rods.

[0044] A rotatable shaft is installed on each of the two crossbars, an anti-collision frame 10 is installed between the two shafts, and the fire fighting unit is installed between the anti-collision frames 10 and rotates synchronously with the anti-collision frames 10. A first driving motor 8 is installed above the top crossbar, and the output shaft of the first driving motor 8 is coaxially connected with the shaft at the top to drive the shaft to rotate, thereby driving the anti-collision frame 10 and the fire fighting unit to rotate.

[0045] like Figure 4 As shown in FIG. 1 , the fire fighting unit includes a driving column 11 and a rotating disk 15 installed in the driving column 11. The rotating disk 15 has a structure as shown in FIG. Figure 5 and Figure 6 As shown, a rotating hole is respectively opened inwardly on both sides of the rotating disk 15, and an axial hole is coaxially opened in the rotating holes on both sides, and 7 locking teeth 16 are circumferentially and equidistantly arranged in the gap between the rotating hole on the right side and the axial hole.

[0046] A spray station 12 is installed on the left side of the turntable 15, and a connecting station is installed on the right side of the turntable 15. A water distribution chamber 18 is opened in the turntable 15, and the water distribution chamber 18 is a circular chamber. A water outlet pipe 17 connected to the water distribution chamber 18 is opened inward from the spray station 12, and a water inlet pipe connected to the other end of the water distribution chamber 18 is opened inward from the connecting station. The inlet of the water inlet pipe is connected to the bellows 9 of the fire water pipe. The high-pressure water sprayed by the fire hydrant can directly enter the water inlet pipe through the fire water pipe, and is introduced into the water distribution chamber 18 by the water inlet pipe, and finally directly sprayed out from the water outlet pipe 17, sprayed to the fire point, and completed the fire extinguishing work.

[0047] A rotating disk 13 is also installed on the spraying platform 12. A second driving motor is installed in the spraying platform 12. The output shaft of the second driving motor is coaxially connected with the rotating disk 13. The rotating disk 13 is driven to rotate synchronously by the rotation of the output shaft of the second driving motor. The rotating disk 13 is in close contact with the end surface of the spraying platform 12, and a plurality of spray holes are equidistantly opened on the rotating disk 13 in the circumferential direction. The shape of each spray hole is different. In this example, there are a total of four spray holes of different shapes, including the following: Figure 6 Two types are shown, including a converging nozzle whose inner radial end connected to the end of the water outlet pipe 17 gradually decreases, a diffusing nozzle whose inner radial end located at the top of the rotating disk 13 away from the water outlet pipe 17 gradually increases, and a separation nozzle and a honeycomb-shaped water mist nozzle respectively arranged on both sides of the rotating disk 13 to increase the number of water columns.

[0048] When in use, there must be a spray hole on the rotating disk 13 that is aligned with and connected to the end of the water outlet pipe 17. Among them, the inner diameter of the aggregation nozzle is smaller than the inner diameter of the water outlet pipe 17. When the high-pressure water flows through the aggregation nozzle, the water pressure and water flow can be gathered, increasing the spray distance and the pressure of the sprayed water flow. The inner diameter of the diffusion nozzle is larger than the inner diameter of the water outlet pipe 17. When the high-pressure water flows through the diffusion nozzle, the water pressure and water flow can be diffused. Although it will reduce the spray distance, it can expand the spraying area. The inner diameter of the separation nozzle is equal to the inner diameter of the water outlet pipe 17. When the high-pressure water flows through the separation nozzle, it can separate a high-pressure water flow into multiple parallel high-pressure water flows, divert the water flow, and increase the spray area after the water flow is sprayed. The water mist nozzle is provided with a baffle with a number of honeycomb-shaped holes. After the high-pressure water hits the baffle, it will spray out through the honeycomb-shaped holes, and the impact will produce water mist. While generating water flow, it cooperates with the water mist to control the fire in the room and complete the fire extinguishing work.

[0049] A position sensor 14 connected to the central control machine is installed below the spray station 12 to align the water outlet pipe 17. When a fire occurs, the detection unit and the position sensor 14 work together to adjust the position of the fire fighting unit and the direction of the water outlet pipe 17 to accurately strike the fire source and achieve the purpose of extinguishing the fire.

[0050] A rectangular groove is formed on the driving column 11 for accommodating the turntable 15, and a column and a main driving member are installed on both sides of the driving column 11. The column is inserted into the shaft hole on the left side of the turntable 15 and rotates with the column as the axis. The main driving member includes a third driving motor installed on the right side of the driving column 11 and a rotating shaft coaxially connected to the output shaft of the third driving motor, and the rotating shaft is inserted into the shaft hole on the right side of the turntable 15. A dial is also coaxially connected to the rotating shaft, and the dial is integrally formed with a plurality of protrusions that are respectively inserted into the latch teeth 16 on the side facing the turntable 15. The protrusions are inserted into the latch teeth 16, and the dial rotates synchronously with the rotating shaft. When the rotating shaft drives the turntable 15 to rotate, the engagement relationship between the protrusions on the inner side of the dial and the latch teeth 16 on the turntable 15 can further synchronously drive the turntable 15 to rotate, thereby realizing the precise adjustment of the position of the turntable 15.

[0051] In this embodiment, an indoor automatic fire extinguishing system is also included, and the indoor automatic fire extinguishing system is composed of a central control unit, a detection unit, a walking unit, a driving unit, a water supply unit and a fire fighting unit.

[0052] Among them, the central control unit is the central control machine; the detection unit is the temperature detection module and the on-site detection module; the walking unit is the electric slider; the driving unit is the first driving motor 8 and the third driving motor; the water supply unit is the solenoid valve; the fire fighting unit is the driving column 11, the turntable 15 and the liquid inlet tank.

[0053] The detection unit realizes the detection function of the on-site environment and transmits the detected information to the central control unit through the network and lines. After receiving the real-time data transmitted by the detection unit, the central control unit judges the on-site environment conditions by storing and analyzing the received data and the photographed route.

[0054] When the situation is judged to be normal, the solenoid valve in the water supply unit is kept closed, and the drive unit and the travel unit are kept in standby state.

[0055] When it is determined that there is a fire, the walking unit is first controlled to move, and in conjunction with the position sensor 14 carried on the turntable 15, the data of the position sensor 14 and the detection unit are received by the central control machine to move the fire-fighting unit to the relative position where the fire exists. Then, the driving unit is used to accurately adjust the direction of the water outlet pipe on the turntable 15 so that it is accurately aligned with the fire. The first driving motor 8 is used to control the rotation of the rotating shaft to drive the fire-fighting unit to rotate along the Z axis as a whole. The third driving motor is used to control the turntable 15 to rotate vertically with the plane to complete 360° free angle selection. Then, the solenoid valve is opened to complete the connection of the fire water pipe, and the fire-fighting water pipe is connected to the fire-fighting alarm without blind spots.

[0056] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
