Description

TECHNICAL FIELD

[0001] The embodiment of the present application relates to the field of fire extinguishing device control, in particular to a pressure stabilizing control device applied in a non-pressure perfluorocyclohexanone fire extinguishing device. BACKGROUND

[0002] The non-pressure perfluorocyclohexanone fire extinguishing device is a new type of fire extinguishing device newly listed in recent years, and its technical feature is that the non-starting state is a normal pressure state, which is different from the technical feature that the traditional gas fire extinguishing system is carried by a pressure container and a driving medium, thereby effectively reducing maintenance and inspection costs. The working principle of the current mainstream non-pressure perfluorocyclohexanone fire extinguishing device is that the gas generator is activated to push the piston device to push the fire extinguishing medium into the pipeline. The working principle of the gas generator is that the electric igniter first receives an electronic pulse current, the electric bridge wire in the electric igniter rapidly generates heat after receiving the ignition current, and ignites the primary fire transfer powder also placed in the electric igniter. The energy generated by the combustion of the primary fire transfer powder is output through a small hole on the shell of the electric igniter, and the gas generating agent in the gas generating chamber receives the ignition energy transmitted by the electric igniter. A large amount of gas mainly composed of nitrogen is generated by the rapid combustion of the gas generating agent in the gas generator, and the gas is released into the device through the exhaust hole on the shell of the gas generator, thereby completing the entire working process of the gas generator. At the same time, the device has a liquid level feedback device to monitor whether the fire extinguishing medium in the device leaks, and generally uses a photoelectric liquid level switch to realize the function. The device characteristics determine that the current is not easy to be too large, and generally more than 300mA current will damage the device, which seriously affects the overall working life of the fire extinguishing device. At the same time, the safety of the circuit device is also low due to the characteristics of the fire extinguishing device. SUMMARY

[0003] The embodiment of the present application provides a pressure stabilizing control device applied in a non-pressure perfluorocyclohexanone fire extinguishing device, so as to at least solve the problem of low circuit safety in the related art.

[0004] According to one embodiment of the present application, a pressure stabilizing control device applied in a non-pressure perfluorocyclohexanone fire extinguishing device is provided, which comprises a cover body and a circuit for controlling the fire extinguishing device, a circular groove is formed in the cover body, a control box for placing the circuit for controlling the fire extinguishing device and a piston for covering the fire extinguishing agent outlet are fixedly arranged in the circular groove, the piston is fixedly connected with a rope, and the other end of the rope is fixedly connected with the cover body.

[0005] Further, the control box is a semicircular control box.

[0006] Further, the rope is an elastic rope.

[0007] Further, a baffle is fixedly arranged above the control box in the circular groove.

[0008] Further, the baffle and the gap of the control box are provided with a filling layer.

[0009] Further, the circuit for controlling the fire extinguishing device comprises a stable starting circuit and a liquid level switch anti-surge circuit.

[0010] Further, the liquid level switch anti-surge circuit comprises a transient voltage suppressor element, an air discharge tube element, a pressure sensitive resistor element and an inductor element.

[0011] Further, the stable starting circuit comprises a single-chip microcomputer and two solid-state relays coupled to the single-chip microcomputer for controlling starting of the single-chip microcomputer.

[0012] According to the present application, since the control box of the device circuit is arranged in the recess on the cover body, the control box is protected by the protrusion around the recess of the cover body and is not easily damaged in normal cases, the elastic rope installed on the piston can prevent the piston from directly hitting the control box when the piston is in the action of launching the fire extinguishing bomb, thereby further ensuring the safety of the circuit, the baffle and the filling layer can prevent the control box from being directly contacted and the pressure acting on the control box can be buffered, and the anti-surge circuit arranged in the circuit can prevent the current in the circuit from being too large to damage the circuit.

[0018] Clearly, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0019] Embodiment: A pressure stabilizing control device applied in a non-pressure storage perfluorocyclohexanone fire extinguishing device, comprising a cover 1 and a circuit for controlling the fire extinguishing device, as shown in Figure 1 and Figure 2 , the cover 1 is the cover 1 of the fire extinguishing device, in the embodiment, a circular groove 11 is formed on the cover 1, the circular groove 11 naturally forms a protrusion 12 around the circular groove 11, a control box 13 for placing the circuit for controlling the fire extinguishing device and a piston 14 for covering the fire extinguishing agent outlet are fixedly arranged in the circular groove 11, the piston 14 is used to be pushed out by the air pressure when the fire extinguishing device is started, and the fire extinguishing agent ejection action is completed.

[0020] In the embodiment, the control box 13 is a semicircular control box 13, and occupies 3 / 5 of the area of the circular groove 11, one side of the arc surface of the semicircular control box 13 is attached to the side wall of the groove, which ensures that the control box 13 is more stable, and the piston 14 is arranged at the center of the other 2 / 5 of the groove, a rope is fixedly connected to the piston 14, the rope is a elastic rope in the embodiment, the other end of the elastic rope is fixed to the cover 1 and located at the position of the protrusion 12 around the circular groove 11, the position of the elastic rope fixed to the cover 1 is close to the near point of the piston 14, which can ensure that the piston 14 does not directly hit the control box 13 when the fire extinguishing bomb is started. A baffle is arranged above the control box 13 in the circular groove 11, the baffle is fixedly arranged on the inner wall of the circular groove 11, and has the same area as the upper top surface of the control box 13, and the baffle has a gap from the upper top surface of the control box 13, in the embodiment, the distance between the baffle and the upper top surface of the control box 13 is two millimeters, the arrangement of the baffle can ensure that the control box 13 is not directly contacted, and further ensure that the circuit in the control box 13 is more secure. A filling layer is arranged in the gap between the baffle and the control box 13, the filling layer is used to buffer the pressure received by the baffle, in the embodiment, the filling layer is made of a foaming agent.

[0021] Referring to Figure 3 and Figure 4As shown, the circuit for controlling the fire extinguishing device comprises a stable starting circuit and a liquid level switch surge protection circuit. The stable starting circuit comprises two solid state relays and a single chip microcomputer coupled to the two solid state relays. K1 uses normally open contacts, and K2 uses normally closed contacts. The normally open contacts of K1 and the normally closed contacts of K2 are in a short circuit state of the electric bridge wire of the gas generator. When a starting signal is received, the normally closed contacts of K2 are disconnected, and the short circuit state of the electric bridge wire of the gas generator is unlocked. In this embodiment, the single chip microcomputer is set to turn on K1 after 500 ms, and the electric bridge wire of the gas generator is powered on to start the device. The liquid level switch surge protection circuit comprises a transient voltage suppressor element, an air discharge tube element coupled to the transient voltage suppressor, a pressure sensitive resistor element, and an inductor element. The inductor in the circuit plays a role in resisting changes in current. When a surge passes through the inductor, the air discharge tube absorbs most of the current, and then the transient voltage suppressor and the pressure sensitive resistor absorb the residual current, thereby achieving the function of surge protection and effectively protecting the rear-end devices of the circuit.

[0022] In this embodiment, the control box 13 of the device circuit is arranged in the recess by arranging a circular recess 11 on the cover 1. The control box 13 is protected by the protrusions 12 around the recess of the cover 1 and is not easily damaged in normal circumstances. The elastic rope arranged on the piston 14 ensures that the piston 14 does not directly hit the control box 13 when the fire extinguishing bomb is launched, thereby further ensuring the safety of the circuit. The arrangement of the baffle and the filling layer ensures that the control box 13 is not directly contacted, and the pressure acting on the control box 13 can be buffered. A surge protection circuit is arranged in the circuit to prevent the current in the circuit from being too large to damage the circuit.
