Technical Field

[0001] This application relates to the field of fire extinguishing equipment technology, and in particular to an automatic fire extinguishing equipment. Background Technology

[0002] Fire is a serious disaster that poses a huge threat to human life and property. With social development and technological advancements, people have increasingly higher demands for fire prevention and control technologies. Traditional firefighting methods mainly rely on manual operation, but this method has many limitations, such as slow response time and low firefighting efficiency. To overcome these shortcomings, automatic fire suppression systems have emerged.

[0003] Currently, automatic fire suppression systems have made significant progress. Common automatic fire suppression systems include automatic sprinkler systems, gas extinguishing systems, and fire detection tube systems. These systems automatically detect fires using heat, smoke, or flame detectors and automatically activate the extinguishing devices when a fire occurs.

[0004] Although existing technologies have improved firefighting efficiency to some extent, traditional manual fire extinguishers still have many problems. Manual fire extinguishers are limited by the reaction speed and physical strength of personnel, and cannot quickly cover the fire source in time, which may lead to the spread of the fire, make it impossible to effectively control the fire, delay the firefighting opportunity, and increase the risk of casualties and property damage. Utility Model Content

[0005] The purpose of this application is to address the problem that manual fire extinguishers are limited by the reaction speed and physical strength of personnel, making it impossible to cover the fire source in a timely manner, which may lead to the spread of the fire, the inability to effectively control the fire, and thus delay the opportunity to extinguish the fire, increasing the risk of casualties and property damage. This application provides an automatic fire extinguishing device.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution:

[0007] An automatic fire extinguishing device includes a U-shaped mounting frame with a connection port in the middle section. A pressure tank is symmetrically arranged inside the U-shaped mounting frame. A transmission rod is symmetrically hinged to one end of the U-shaped mounting frame, with one end of the transmission rod installed inside the connection port. Multiple nozzles are fixedly connected to the bottom of the transmission rod. A solenoid valve is fixedly connected to the output end of the pressure tank, and a guide pipe is fixedly connected to the output end of the pressure tank. The output end of the guide pipe is fixedly connected to the input end of the multiple nozzles. Fire sensors are installed at each of the four corners of the U-shaped mounting frame, and an adjustment assembly is installed at one end of the U-shaped mounting frame.

[0008] By adopting the above technical solution, and by setting up the adjustment component in conjunction with the fire sensor, solenoid valve, and multi-nozzle head, it is convenient to use the fire sensor to monitor the fire in real time. When the solenoid valve is opened, the multi-nozzle head is driven to rotate in the direction of the fire, thereby guiding the extinguishing agent inside the pressurized tank to be automatically sprayed in the direction of the fire through multiple nozzles. This facilitates real-time monitoring of the occurrence of the fire and timely spraying of extinguishing agent in the direction of the fire by multiple nozzles, thus improving the safety of the device.

[0009] Furthermore, the adjustment assembly includes a first bevel gear fixedly connected to the hinge end of the transmission rod, an adjustment motor symmetrically fixedly connected to one end of the U-shaped mounting bracket, and a second bevel gear meshing with the first bevel gear fixedly connected to the output end of the adjustment motor.

[0010] By adopting the above technical solution, and by setting the bevel gear one and bevel gear two to work together, the starting adjustment motor can drive bevel gear two to mesh with bevel gear one, and cause bevel gear one to drive the transmission rod to deflect around the hinge shaft, which effectively improves the practicality of the device.

[0011] Furthermore, each of the four corners of the U-shaped mounting bracket is fixedly connected to an adjusting shaft, one end of which is movably fitted with an adjusting rod. The fire sensor is fixedly connected to the end of the adjusting rod away from the adjusting shaft, and a locking assembly is installed at one end of the adjusting shaft.

[0012] By adopting the above technical solution, and by setting up the locking assembly in conjunction with the adjusting shaft and adjusting rod, it is convenient to allow the adjusting rod to be unfolded around the U-shaped mounting frame on both sides after it is pulled around the adjusting shaft. This allows the adjusting rod to drive the fire sensor away from both sides of the U-shaped mounting frame and unfold to accommodate it. After that, the locking assembly is tightened to fix the adjusting rod, thereby facilitating the adjustment of the fire sensor's monitoring range and improving the practicality of the device.

[0013] Furthermore, the locking assembly includes a locking screw groove at one end of the adjusting shaft, the adjusting shaft is threadedly connected to a locking nut through the locking screw groove, and the adjusting rod is installed between the locking nut and the U-shaped mounting bracket.

[0014] By adopting the above technical solution, and by setting the locking screw groove and locking nut to work together, it is easy to push the adjusting rod along the length of the adjusting shaft to form an abutment with the U-shaped mounting bracket when the locking nut is tightened, thereby fixing the adjusting rod and effectively improving the practicality of the device.

[0015] Furthermore, a pair of ejection grooves are symmetrically provided at one end of the U-shaped mounting bracket, an ejection slide rod is slidably connected inside the ejection groove, an abutment head is fixedly connected to one end of the ejection slide rod, and an ejection assembly is installed at one end of the U-shaped mounting bracket.

[0016] By adopting the above technical solution, and by setting the ejection assembly in conjunction with the ejection slide rod and the ejection groove, rotating the ejection assembly can push the ejection slide rod to move the contact head along the length direction of the ejection groove, and make the contact head abut against the wall along the length direction of the U-shaped mounting bracket, thereby realizing the rapid fixed installation of the U-shaped mounting bracket and effectively improving the applicability of the device.

[0017] Furthermore, the ejection assembly includes an ejection screw rotatably connected inside the ejection groove, one end of the ejection groove having an ejection screw groove adapted to the ejection screw, and one end of the ejection screw being fixedly connected to an ejection knob.

[0018] By adopting the above technical solution, and by setting the ejector screw and ejector screw groove to work together, rotating the ejector knob can drive the ejector screw and ejector screw groove to form a threaded connection, and push the ejector slide rod to drive the contact head to move along the length direction of the ejector slide groove, which effectively improves the practicality of the device.

[0019] Furthermore, a rubber gasket is fixedly connected to one end of the contact head.

[0020] By adopting the above technical solution, and by using rubber pads in conjunction with the contact head, a flexible contact is formed between the contact head and the wall, thereby reducing wear between the contact head and the wall and improving the contact stability between the contact head and the wall.

[0021] In summary, this application includes at least one of the following beneficial effects:

[0022] 1. By setting up the adjustment component in conjunction with the fire sensor, solenoid valve, and multi-nozzle head, it is convenient to use the fire sensor to monitor the fire situation in real time. When the solenoid valve is opened, it drives the multi-nozzle head to rotate in the direction of the fire, thereby guiding the extinguishing agent inside the pressurized tank to be automatically sprayed in the direction of the fire through multiple nozzles. This facilitates real-time monitoring of the occurrence of the fire and timely spraying of extinguishing agent in the direction of the fire by multiple nozzles, thus improving the safety of the device.

[0023] 2. By setting the ejector assembly in conjunction with the ejector slide rod and ejector groove, rotating the ejector assembly can push the ejector slide rod to move the contact head along the length of the ejector groove, and make the contact head abut against the wall along the length of the U-shaped mounting bracket, thereby achieving rapid fixed installation of the U-shaped mounting bracket and effectively improving the applicability of the device.

[0030] The following is in conjunction with the appendix Figure 1 —4 provides further detailed description of this application.

[0031] This application discloses an automatic fire extinguishing device.

[0032] Reference Figure 1 - Figure 3 An automatic fire extinguishing device includes a U-shaped mounting frame 1, a connection port 2 in the middle section of the U-shaped mounting frame 1, a pressure tank 3 symmetrically arranged inside the U-shaped mounting frame 1, a transmission rod 4 symmetrically hinged to one end of the U-shaped mounting frame 1, one end of the transmission rod 4 installed inside the connection port 2, a multi-nozzle head 5 fixedly connected to the bottom of the transmission rod 4, a solenoid valve 6 fixedly connected to the output end of the pressure tank 3, and a guide pipe 7 fixedly connected to the output end of the pressure tank 3, the output end of the guide pipe 7 fixedly connected to the input end of the multi-nozzle head 5, fire sensors 8 installed at the four corners of the U-shaped mounting frame 1, and an adjustment component installed at one end of the U-shaped mounting frame 1.

[0033] The adjustment assembly includes a bevel gear 9 fixedly connected to the hinge end of the transmission rod 4, an adjustment motor 10 symmetrically fixedly connected to one end of the U-shaped mounting bracket 1, and a bevel gear 11 meshing with the bevel gear 9 fixedly connected to the output end of the adjustment motor 10.

[0034] Furthermore, each of the four corners of the U-shaped mounting bracket 1 is fixedly connected to an adjusting shaft 12, and an adjusting rod 13 is movably sleeved on one end of the adjusting shaft 12. The fire sensor 8 is fixedly connected to the end of the adjusting rod 13 away from the adjusting shaft 12, and a locking component is installed on one end of the adjusting shaft 12.

[0035] Furthermore, the locking assembly includes a locking screw groove 14 opened at one end of the adjusting shaft 12, and the adjusting shaft 12 is threadedly connected to a locking nut 15 through the locking screw groove 14. The adjusting rod 13 is installed between the locking nut 15 and the U-shaped mounting bracket 1.

[0036] In use, first rotate the adjusting rod 13 with the adjusting shaft 12 as the center to move the fire sensor 8 and unfold it to the four corners of the U-shaped mounting bracket 1. Then tighten the locking nut 15 so that the locking nut 15 and the locking screw groove 14 form a threaded connection. Push the adjusting rod 13 along the length of the adjusting shaft 12 to form abutment and fixation with the U-shaped mounting bracket 1 to complete the fixed installation of the fire sensor 8. The fire sensor 8 is used to monitor the fire at the four corners of the U-shaped mounting bracket 1 in real time.

[0037] Then, when the fire sensor 8 detects a fire, it sends a fire signal to the regulating motor 10, causing the regulating motor 10 to drive the bevel gear 11 to mesh with the bevel gear 9. The bevel gear 9 then drives the transmission rod 4 to deflect around the hinge axis in the direction of the fire. At the same time, the transmission rod 4 drives the output end of the multi-nozzle 5 to face the direction of the fire. Then, the solenoid valve 6 is activated to release the seal on the output end of the transmission rod 4, allowing the extinguishing agent stored in the pressurized tank 3 to be introduced into the multi-nozzle 5 through the guide pipe 7. The agent is then sprayed in the direction of the fire through the multi-nozzle 5. This facilitates real-time monitoring of the fire and timely spraying of extinguishing agent in the direction of the fire by the multi-nozzle 5, thus improving the safety of the device.

[0038] Reference Figure 1 and Figure 4 A pair of ejection grooves 23 are symmetrically provided at one end of the U-shaped mounting bracket 1. An ejection slide rod 17 is slidably connected inside the ejection groove 23. An abutment head 18 is fixedly connected to one end of the ejection slide rod 17. An ejection assembly is installed at one end of the U-shaped mounting bracket 1.

[0039] The ejector assembly includes an ejector screw 19 rotatably connected inside the ejector slide 23, an ejector screw groove 20 adapted to the ejector screw 19 is provided at one end of the ejector slide 17, and an ejector knob 21 is fixedly connected to one end of the ejector screw 19.

[0040] Furthermore, a rubber gasket 22 is fixedly connected to one end of the contact head 18.

[0041] In use, by manually rotating the ejection knob 21, the ejection knob 21 drives the ejection screw 19 to form a threaded connection with the ejection slide rod 17 through the ejection screw groove 20, and pushes the ejection slide rod 17 outward along the length direction of the ejection slide groove 23. At the same time, the ejection slide rod 17 pushes the contact head 18, which drives the rubber gasket 22 to form a flexible contact with the wall, thereby making the U-shaped mounting bracket 1 contact and fix it to the wall. This facilitates the quick fixing and installation of the U-shaped mounting bracket 1, and further improves the practicality of the device.

[0042] The implementation principle of the automatic fire extinguishing device in this embodiment is as follows: First, by manually rotating the ejection knob 21, the ejection knob 21 drives the ejection screw 19 to form a threaded connection with the ejection slide rod 17 through the ejection screw groove 20, and pushes the ejection slide rod 17 outward along the length direction of the ejection slide groove 23. At the same time, the ejection slide rod 17 pushes the contact head 18 to drive the rubber pad 22 to form a flexible contact with the wall, thereby forming a contact fixation between the U-shaped mounting bracket 1 and the wall.

[0043] Then, rotate the adjusting rod 13 with the adjusting shaft 12 as the center, drive the fire sensor 8 to move and unfold to the four corners of the U-shaped mounting bracket 1. Then tighten the locking nut 15 so that the locking nut 15 and the locking screw groove 14 form a threaded connection, and push the adjusting rod 13 to form abutment and fixation with the U-shaped mounting bracket 1 along the length direction of the adjusting shaft 12. The fire sensor 8 is used to monitor the fire at the four corners of the U-shaped mounting bracket 1 in real time.

[0044] Then, when the fire sensor 8 detects a fire at a certain location, the fire sensor 8 sends a fire signal to the regulating motor 10, which in turn drives the bevel gear 11 to mesh with the bevel gear 9. The bevel gear 9 then drives the transmission rod 4 to deflect around the hinge axis in the direction of the fire. At the same time, the transmission rod 4 drives the output end of the multi-nozzle 5 to face the direction of the fire. Then, the solenoid valve 6 is activated to release the seal on the output end of the transmission rod 4, allowing the extinguishing agent stored inside the pressurized tank 3 to be introduced into the interior of the multi-nozzle 5 through the guide pipe 7, and then sprayed in the direction of the fire through the multi-nozzle 5.
