[0002] Heptafluoropropane is a clean gas fire extinguishing agent that mainly uses chemical fire extinguishing and also has physical fire extinguishing effects. Heptafluoropropane has the characteristics of being colorless, odorless, low in toxicity and non-conductive. It will not cause damage to property and precision facilities. Therefore, fire extinguishers made of heptafluoropropane are widely used in computer rooms, communication rooms, substations, precision instrument rooms, generator rooms, oil depots and other places. In actual use, it has the advantages of simple operation, stable structure and good use effect.

[0003] The prior art discloses a suspended double-start HFC-227ea gas fire extinguishing device with announcement number: CN215387196U, which includes an electromagnetic drive switch, a container valve, an electromagnet, a spring rod, an electromagnetic valve, a nozzle, a signal feedback device, a pressure display, a temperature sensor, a steel cylinder, a connecting bolt, a telescopic rod, a lifting lug and a mounting plate. The first step is an electromagnetic start method: using an electromagnetic drive switch. Generally speaking, the electromagnetic drive switch will be equipped with a controller. The electromagnetic drive switch is started by manually operating the controller. The electromagnetic drive switch sends an electrical signal to the signal feedback device to energize the electromagnet. After the electromagnet is energized, the electromagnetic valve is pulled to move to both sides, so that the container valve is opened, and HFC-227ea flows out from the nozzle, thereby achieving fire extinguishing; the second step is a temperature control start method: the temperature sensor sets the opening threshold, and the temperature sensor is used to transmit an electrical signal to the signal feedback device to energize the electromagnet. After the electromagnet is energized, the electromagnetic valve is pulled to move to both sides by magnetic force, so that the container valve is opened, and HFC-227ea flows out from the nozzle, thereby achieving fire extinguishing.

[0004] When the above utility model is installed, the cylinder needs to be lifted to a suitable position before the installation work can be carried out.

[0016] (III) Beneficial effects

[0017] Compared with the prior art, the utility model provides a signal feedback type heptafluoropropane fire extinguishing device, which has the following beneficial effects:

[0018] (1) The utility model adopts a socket hole plate. When the signal feedback type HFC-227ea fire extinguishing device is actually used, it is necessary to install a processor, a wireless signal receiver and an alarm in the control room. The processor is electrically connected to the power supply, the alarm and the wireless signal receiver through wires. At this time, the operator can first connect the installation cover to the inner top surface of the installation space. After completing the installation work, the operator pulls the two sets of steel cables by hand. The two sets of groove wheels below will support the two sets of steel cables, so that the two sets of steel cables pull the socket hole plate and the cylinder upward. When the two sets of installation screws pass through the two sets of installation holes respectively, the operator uses the two sets of openings to connect the two sets of installation nuts clockwise to the two sets of installation screws. When the two sets of installation nuts are in close contact with the inner bottom surface of the covering cover, the installation of the cylinder is completed. The operator can use the hands to wrap the two sets of steel cables around the two sets of installation rods respectively. The four sets of limit blocks prevent the two sets of steel wires from detaching from the two sets of through holes. The four sets of installation shafts play the role of installation.

The processor can make the alarm work, and the operating workers in the central control room can know that a fire has occurred in the working space. At the same time, the HFC-227ea fire extinguishing agent enters the interior of the nozzle through the nozzle, and finally the HFC-227ea fire extinguishing agent is sprayed out through the nozzle. The sprayed HFC-227ea fire extinguishing agent can extinguish the open flame. Through the set socket plate, the operating workers can lift the cylinder on the ground without the help of lifting equipment, reducing the installation cost of the signal feedback HFC-227ea fire extinguishing device.

[0019] (2) The utility model adopts an installation cover. When the cylinder needs to be installed on the top surface of the space, the operator first climbs up and moves the installation cover to a suitable position, and then the drill bit of the drilling equipment penetrates a group of movable orifice plates, a group of magnet orifice plates and a group of guide hoppers on the same side, and finally the drill bit contacts the wall of the top surface of the space. When the drilling equipment is working, the drill bit will rotate, and the drilling equipment will push the group of lifting orifice plates on the same side to move up. This group of lifting orifice plates will squeeze the two groups of elastic springs and the group of telescopic hoses on the same side. In this process, the debris generated will pass through the group of lifting orifice plates on the same side. The guide hopper and a group of magnet hole plates on the same side enter the interior of a group of telescopic hoses on the same side. When the drilling work is completed, the operator can separate the group of magnet hole plates on the same side from the installation cover, and then pour the debris inside this group of telescopic hoses to a suitable position. At this time, the expansion screws can be used to penetrate the group of guide hoppers on the same side and install them inside the drilled hole. The use of another group of telescopic hoses can be obtained by the same operation. By setting up the installation cover, it is possible to avoid the debris generated during the drilling process from filling the entire space, thereby improving the practicality of the signal feedback type HFC-227ea fire extinguishing device.

[0037] Working principle:

[0038] When the signal feedback type HFC-227ea fire extinguishing device is actually used, it is necessary to install a processor, a wireless signal receiver and an alarm in the central control room. The processor is electrically connected to the power supply, the alarm and the wireless signal receiver through wires. At this time, the operator can first connect the installation cover 14 to the inner top surface of the installation space. After completing the installation work, the operator pulls the two sets of steel cables 22 by hand. The two sets of groove wheels 26 below will support the two sets of steel cables 22, so that the two sets of steel cables 22 pull the socket plate 20 and the cylinder 1 upward. When the two sets of installation screws 16 pass through the two sets of installation holes 15 respectively, the operator uses the two sets of openings 18 to sleeve the two sets of installation nuts 17 on the two sets of installation screws 16 clockwise.

The sprayed HFC-227ea fire extinguishing agent can extinguish the open flame. Through the set socket hole plate 20, the operating workers can lift the cylinder 1 on the ground without the help of lifting equipment, which reduces the installation cost of the signal feedback type HFC-227ea fire extinguishing device. At the same time, when it is necessary to install the cylinder 1 on the top surface of the space, the operating workers first climb up and move the installation cover 14 to a suitable position, and then the drill bit of the drilling equipment passes through a group of movable hole plates 31 on the same side, a group of magnet hole plates 29 on the same side and a group of guide hoppers 28 on the same side, and finally the drill bit contacts the top wall of the space, and the drilling equipment During operation, the drill bit will rotate, and the drilling equipment will push up a set of lifting orifice plates on the same side, and this set of lifting orifice plates will squeeze the two sets of elastic springs 32 and the telescopic hose 33 on the same side.
