Description

Technical Field

[0001] The utility model belongs to the technical field of fire fighting equipment, and in particular relates to an automatic ejection device for a small fire extinguisher. Background Art

[0002] In the field of fire fighting equipment, small fire extinguishers are increasingly used, especially in the early stages of fire fighting, where they play a vital role. Traditional small fire extinguishers are light and portable, suitable for a variety of fire types, and are designed to be reliable, making them ideal fire fighting equipment for homes, offices and other places.

[0003] Although traditional small fire extinguishers have played a certain role in firefighting, they still have some defects that cannot be ignored: traditional small fire extinguishers usually need to be operated manually, which is particularly difficult in some special environments, such as when the fire scene is full of smoke, the temperature is extremely high, or the location is difficult to access. At the same time, traditional fire extinguishers are also incapable of firefighting tasks that require remote or aerial operations. Utility Model Content

[0004] The utility model aims to provide an automatic ejection device for a small fire extinguisher, which can quickly launch the fire extinguisher (fire extinguishing bomb) to the fire source, realize remote fire extinguishing and improve the fire extinguishing efficiency.

[0005] In order to achieve the above-mentioned purpose, the technical solution of the utility model is: an automatic ejection device for a small fire extinguisher, comprising an ejection mechanism, a control mechanism and a trigger mechanism, wherein the control mechanism is connected to the trigger mechanism and the ejection mechanism respectively; the trigger mechanism is used to detect the fire source and send the detection information to the control mechanism; the control mechanism is used to receive the information of the trigger mechanism and send an ejection instruction to the ejection mechanism according to the information sent by the trigger mechanism; the ejection mechanism comprises a base and a driving structure and an ejection arm arranged in the base, wherein the driving structure is used to drive the ejection arm to eject; a feeding port is provided on one side of the base, and the fire extinguisher enters the inner cavity of the base through the feeding port; a discharge port is provided on the side of the base facing the moving direction of the ejection arm, and the ejection arm can eject the fire extinguisher in the inner cavity of the base from the discharge port.

[0006] Furthermore, a guide rod is provided in the base, a guide hole is provided on the ejection arm, and the ejection arm is slidably connected to the guide rod through the guide hole.

[0007] Furthermore, the driving structure includes a driving member, an ejection assembly and a locking assembly. A fixed seat is provided on the base. The locking assembly is used to connect the ejection arm and the base, and the driving member can unlock the locking assembly; the ejection assembly is used to connect the base and the ejection arm, and the ejection assembly can eject the ejection arm after the locking assembly is unlocked; the driving member is driven by the control mechanism.

[0008] Furthermore, the locking assembly includes a buckle and a tooth, a fixing rod is connected to the fixing seat, a sliding hole is provided on the buckle, the fixing rod passes through the sliding hole and the sliding hole is slidably connected to the fixing rod; the tooth is connected to the ejection arm; a groove for clamping the tooth is provided on the buckle; the driving member can drive the buckle to slide on the fixing rod to realize the connection and separation of the buckle and the tooth.

[0009] Furthermore, a driving end of the driving member is connected to a trigger rod, and the other end of the trigger rod is connected to the buckle.

[0010] Furthermore, the locking assembly, the trigger rod, the fixing seat, and the fixing rod are respectively provided with two groups, and the driving member is used for synchronously driving the two groups of the trigger rods to move.

[0011] Furthermore, the ejection assembly adopts a compression spring, and when the locking assembly is locked, the compression spring is in a compressed state.

[0012] Furthermore, the ejection arm is provided with a handle for pulling back the ejection arm.

[0014] The working principle of this technical solution is: load this device on the drone, and put the fire extinguisher (fire extinguishing bomb) into the inner cavity of the base from the feed port. After the trigger mechanism detects the fire source, it sends the detection information to the control mechanism, and the control mechanism sends an ejection command to the ejection mechanism, and the ejection mechanism ejects the fire extinguisher (fire extinguishing bomb) in the inner cavity of the base to extinguish the fire. Specifically: the drive member starts after receiving the ejection command, driving the two sets of trigger rods to move away from each other, and the trigger rod drives the buckle to move, so that the tooth end of the latch is disengaged from the slot of the buckle, and the latch is separated from the restraint of the buckle, and will be ejected in the direction of the discharge port under the action of the ejection assembly. In this process, the fire extinguisher (fire extinguishing bomb) in the inner cavity of the base will be pushed, and the fire extinguisher (fire extinguishing bomb) will be ejected from the direction of the discharge port.

[0015] The beneficial effect of this technical solution is that once the fire source is detected, the control mechanism immediately activates the ejection mechanism, so that the fire extinguisher automatically pops out and is placed at the fire source. This technical solution can greatly improve the efficiency and safety of fire fighting, especially in fire scenes where it is difficult for personnel to approach the fire source or where a quick response is required. Remote control can reduce the risk of firefighters approaching the fire source. BRIEF DESCRIPTION OF THE DRAWINGS
