Automatic sprinkler system

Abstract

This utility model discloses an automatic sprinkler system, including: a main pipe connected to a water pump, and several branch pipes connected to the main pipe; a water circuit control device for controlling the opening and closing of the water circuit; a sprinkler device for expanding the spray area during fire extinguishing; and a sensor for monitoring the temperature within the electric field adsorption unit. The water circuit control can be achieved through the linkage of the sensor and the solenoid valve. An alarm is installed on the electric field adsorption unit or control cabinet to notify personnel in the event of a fire. When a fire occurs, the temperature at the outlet rises, and the thermocouple senses the change in ambient temperature. When the ambient temperature exceeds the threshold set by the thermocouple, the power supply to the electric field is cut off via an electrical signal (to prevent short circuits and electric shock to rescue personnel during sprinkler operation), and an audible and visual alarm is triggered. Simultaneously, the solenoid valve is opened via an electrical signal, and water flows through a manual shut-off valve and the solenoid valve into the main pipe, then into the branch pipes and is sprayed out by the sprinkler device, achieving the purpose of extinguishing the fire in its initial stage.

Description

Technical Field

[0001] This utility model relates to the field of fire protection facilities technology, and more specifically, to an automatic sprinkler system. Background Technology

[0002] During operation, the environmental protection equipment introduces gas through one end (the electric field adsorption unit), where it adsorbs impurities such as tar via a plate electric field (and activated carbon in the activated carbon box). However, the plate electric field poses a potential risk of generating high-temperature electric sparks due to partial short circuits in the electric field module. Given that the tar it captures has an ignition point below 200°C, such electrical faults coupled with flammable materials can easily lead to a fire chain reaction. The applicant previously used this environmental protection equipment but failed to consider the possibility of short circuits and electric sparks in the plate electric field, resulting in two fires and significant economic losses due to the adsorbed tar being flammable. Therefore, improving this environmental protection equipment to prevent fires is the technical problem this application aims to solve. Utility Model Content

Detailed Implementation

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments, so that those skilled in the art can implement it based on the description.

[0029] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0030] like Figures 1-5 As shown, this utility model provides an automatic sprinkler system, including: a main pipe connected to a water pump, and several branch pipes connected to the main pipe. The main pipe is connected to the water pump via a flange, and the end of the main pipe is sealed with a blind flange to form a closed-loop water circuit. It also includes:

[0031] A water circuit control device, installed on the main pipe, is used to control the opening and closing of the water circuit. The device consists of a manual shut-off valve 3 and a solenoid valve 4, connected in series on the main pipe. The manual shut-off valve 3 is located on the side of the main pipe closer to the water pump, and the solenoid valve 4 is located on the side of the main pipe farther from the water pump. The manual shut-off valve 3 is normally open, and the solenoid valve 4 is normally closed. The solenoid valve 4 is electrically connected to the sensor 2, and the solenoid valve 4 and sensor 2 work together to control the opening and closing of the water circuit. The sensor 2 is a thermocouple, an infrared thermal sensor, or a flame detection device.

[0032] A sprinkler device 1 is installed on the branch pipe, which is connected to the main pipe in a vertical direction. The sprinkler device 1 extends through the branch pipe into the interior of the electric field adsorption unit 100. The sprinkler device 1 uses a spiral nozzle to expand the spray area during fire extinguishing, thereby ensuring that each electric field 200 can be sprayed by the sprinkler device 1. The branch pipes are connected by hinges to allow for quick installation and disassembly, facilitating maintenance.

[0033] Sensor 2 is installed at the outlet end of the electric field adsorption unit 100 to monitor the temperature inside the electric field adsorption unit 100. By placing sensor 2 at the outlet end, the excessively high temperature inside the electric field adsorption unit 100 can be effectively avoided from affecting the sensor and causing false alarms. When a fire occurs, as the gas is continuously supplied, heat will be discharged from the outlet end and gradually rise. The temperature can be monitored by sensor 2 to determine whether a fire has occurred.

[0034] The electric field 200 in both the water circuit control device and the electric field adsorption unit 100 is electrically connected to the sensor 2.

[0035] It also includes an alarm 5, which is electrically connected to the sensor 2, and the alarm 5 is an audible and visual alarm.

[0036] The working principle and beneficial effects of the above technical solution are as follows: Through the design of the above structure, the water circuit control can be achieved by the linkage of sensor 2 (i.e., thermocouple) and solenoid valve 4. An alarm 5 is installed on the electric field adsorption unit 100 or the control cabinet, which can alert personnel in the event of a fire. When a fire occurs, the temperature at the outlet rises, and the thermocouple senses the change in ambient temperature. When the ambient temperature exceeds the threshold set by the thermocouple, the power supply to the electric field 200 is cut off by an electrical signal (to prevent short circuits during spraying and electric shock to rescue personnel), and the audible and visual alarm is triggered. At the same time, the solenoid valve 4 is opened by an electrical signal, and the water flows into the main pipe through the manual shut-off valve 3 and the solenoid valve 4, flows into the branch pipe, and is sprayed out by the sprinkler device 1, achieving the purpose of extinguishing the fire in its early stage.

[0037] In the aforementioned embodiments, we mentioned that the sprinkler system uses spiral nozzles to expand the coverage area. In this embodiment, we provide a specific implementation method. The sprinkler system 1 consists of an installation head 6 connected to a branch pipe, a water distributor 7 disposed within the installation head 6, and a diffuser plate 8 disposed on the water distributor 7. The water distributor 7 is located within the installation head 6 and extends from the bottom of the installation head 6 to the outside of the installation head 6. The diffuser plate 8 is movably connected to the water distributor 7. When the water pump supplies fire extinguishing liquid, the fire extinguishing liquid can enter the installation head 6 from the branch pipe and then be sprayed onto the diffuser plate 8 under the guidance of the water distributor 7. After impacting the diffuser plate 8, the fire extinguishing liquid forms an umbrella shape, thereby expanding the coverage area of ​​the fire extinguishing liquid. At the same time, the diffuser plate 8 rotates around the water distributor 7 as a rotation axis under the impact of the fire extinguishing liquid, thereby rotating and throwing the fire extinguishing liquid out of the diffuser plate 8, further increasing the coverage area of ​​the fire extinguishing liquid and reducing fire extinguishing dead zones.

[0038] Furthermore, the mounting head 6 consists of an inlet section 61 and an outlet section 62. The inlet section 61 is a tubular structure and is connected to the branch pipe. The outer wall of the inlet section 61 may be provided with external threads to connect with the branch pipe, thereby facilitating replacement and disassembly.

[0039] The water outlet section 62 is located at the bottom of the water inlet section 61. The water outlet section 62 is a tapered tube that is wider at the top and narrower at the bottom. The end of the water outlet section 62 with a larger diameter is connected to the bottom of the water outlet section 62. Figure 3As shown, the water outlet section 62 adopts a tapered pipe with a narrow opening, which can effectively reduce the flow area of ​​the extinguishing liquid, increase the water flow velocity sprayed from the water outlet section 62, thereby increasing the impact force on the diffuser plate 8 and increasing the diffusion area.

[0040] The water distributor 7 is located within the outlet section 62 and extends from the bottom of the outlet section 62 to the outside of the mounting head 6. The water distributor 7 consists of a fixed end 71, an extension rod 72, a water distributor nozzle 73, and a base 74. The fixed end 71 is a tapered tube, wider at the top and narrower at the bottom. The major diameter of the outer wall of the fixed end 71 is not greater than the major diameter of the inner wall of the outlet section 62, and the minor diameter of the outer wall of the fixed end 71 is not less than the minor diameter of the inner wall of the outlet section 62. Figure 3 As shown, the fixed end 71 can be locked inside the water outlet section 62. The inner wall of the fixed end 71 is provided with at least three connecting strips 711. The extension rod 72 is located on the central axis of the fixed end 71, and the outer wall of the extension rod 72 is connected to the inner wall of the fixed end 71 through the connecting strips 711. The connecting strips 711 are used to fix and install the extension rod 72, and there are gaps between the connecting strips 711 to allow the extinguishing liquid to flow through. At the same time, by controlling the number of connecting strips 711, the flow area of ​​the extinguishing liquid can be further changed. The flow area of ​​the extinguishing liquid can be adjusted by replacing the water distributor 7 as needed on site.

[0041] Furthermore, the bottom of the extension rod 72 extends away from the fixed end 71 and extends to the outside of the mounting head 6. The extension rod 72 extending to the outside of the mounting head 6 allows the water distributor 7 to be used as a universal component and can be applied to mounting heads 6 of different heights, improving the versatility of the water distributor 7 as an accessory.

[0042] The water distributor 73 has a flared structure that is smaller at the top and larger at the bottom. The larger diameter of the bottom of the water distributor 73 is not greater than the smaller diameter of the inner wall of the water inlet section 61. When installing the water distributor 7, it can be directly inserted from the water inlet section 61, which improves the convenience of installation. The flared structure of the water distributor 73 can effectively guide the impact of the extinguishing liquid to the surface of the diffuser plate 8. The top of the water distributor 73 is connected to the bottom of the extension rod 72.

[0043] Furthermore, the bottom of the water divider 73 is provided with a threaded hole 731, which is located on the central axis of the water divider 73. The base 74 is provided with a threaded connecting post 741, which passes through the diffuser 8 along the central axis of the diffuser 8 and is connected to the threaded hole 731 of the water divider 73.

[0044] The diffuser plate 8 is provided with a through hole, the inner diameter of which is not less than the diameter of the connecting column 741. The through hole is located on the central axis of the diffuser plate 8, thereby forming a clearance fit between the through hole and the connecting column 741, so that the diffuser plate 8 can rotate about the connecting column 741 as an axis under the impact of the extinguishing liquid.

[0045] Furthermore, the bottom of the diffuser disk 8 is provided with an annular groove 81 centered on the through hole, and the base 74 is provided with a limiting protrusion 742 adapted to the annular groove 81. The limiting protrusion 742 is located inside the annular groove 81. Through the cooperation between the limiting protrusion 742 and the annular groove 81, the diffuser disk 8 can be limited without affecting the rotation of the diffuser disk 8.

[0046] Furthermore, to reduce blind spots in the coverage of the extinguishing liquid, several water guide strips 82 can be provided at the edge of the diffuser plate 8. These water guide strips 82 extend spirally radially outwards from the through-hole to the outside of the diffuser plate 8, such as... Figure 2 As shown, when the extinguishing liquid leaves the diffuser plate 8 through the spiral radial water guide strip 82, it can drive the diffuser plate 8 to rotate, thereby realizing the rotation of the diffuser plate 8.
