Description

A fire alarm gas cut-off linkage device

Technical field

The utility model belongs to the technical field of fire alarm, and specifically relates to a fire alarm gas cutoff linkage device.

Background technique

Existing buildings and shopping malls generally use piped gas as kitchen fuel. In order to ensure gas safety, flammable gas detection and alarm systems are installed in the kitchen area. As long as a gas leak occurs in the kitchen, the combustible gas alarm controller will immediately electronically control the cut-off valve to close to achieve safety purposes.

However, we found that after the fire was controlled, when firefighters or householders entered the room to check the gas shut-off valve, they did not know whether the valve had been closed, and they still needed to manually rotate the shut-off valve and perform a gas supply test.

In view of this, the present utility model is proposed.

The motor is dynamically connected with the cut-off component to cut off the gas pipeline.

As a preferred embodiment of the present invention, the cutting component includes a runner movably installed in a rubber sealing block. The front side wall of the runner is provided with a tooth groove. The driving end of the motor is fixed with a driving rod. A driving gear and a crown gear are fixed at the end of the rod. The crown gear is arranged on the driving gear, and the driving gear meshes with the tooth slot. A sealing baffle for closing the gas channel is fixed on the outer wall of the runner.

As a preferred embodiment of the present invention, the transmission component is dynamically connected with the crown gear, and the transmission component includes a transmission rod and gears fixed at both ends of the transmission rod. The gear at one end of the transmission rod meshes with the crown gear, and the other end of the transmission rod meshes with the crown gear. The gear at one end meshes with the tooth plate, and the tooth plate is fixed to the lower end of the indicator rod.

As a preferred embodiment of the present invention, the indicator rod moves vertically upward and penetrates the rubber sealing block and the top cover.

As a preferred embodiment of the present invention, the rubber sealing block is movable and sealingly attached to the outer wall of the runner.

Compared with the existing technology, the utility model has the following beneficial effects:

In this utility model, when the motor rotates through the driving rod, the driving rod drives the driving gear to mesh with the tooth grooves provided on the runner. At this time, the rotation of the runner drives the sealing baffle to rotate and separate from the passage opening of the cut-off valve, and rotates to reset, allowing the gas to flow. During this process, the rotation of the crown gear can drive the transmission rod to rotate. The gear at the other end of the transmission rod engages the tooth plate and moves up, thereby driving the tooth plate upward and driving the indicator rod to extend out of the top cover. This can facilitate personnel to know in time. At this time, the valve is open.

The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

Detailed ways

In order to make the purpose, technical solutions and advantages of the embodiments of the present utility model more clear, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model. The following examples are used for illustration. This utility model.

As shown in Figures 1 to 3, a fire alarm gas cut-off linkage device includes a cut-off valve 2 and a cut-off component arranged in the cut-off valve 2. A rubber sealing block 1 is fixed in the cut-off valve 2; the cut-off valve 2 is also provided with There is an indicator rod 5, and the cut-off component is dynamically connected to the indicator rod 5 through a transmission component provided in the cut-off valve 2; a top cover 3 is installed on the cut-off valve 2, and a vertically downward motor 4 is installed on the upper part of the top cover 3. The motor 4 is power-connected with the cutting component to cut off the gas pipeline.

As shown in Figures 1 to 3, in the specific embodiment, the cutting component includes a runner 6 movably installed in the rubber sealing block 1. The front side wall of the runner 6 is provided with a tooth slot 11, and the driving end of the motor 4 is fixed. There is a driving rod 8, and a driving gear 12 and a crown gear 13 are fixed at the end of the driving rod 8. The crown gear 13 is arranged on the driving gear 12, and the driving gear 12 meshes with the tooth groove 11. The outer wall of the runner 6 is fixed with a seal for closing. The sealing baffle 7 of the gas channel electrically connects the motor 4 to the indoor fire sensor. After the motor 4 receives the fire signal, the motor 4 rotates through the driving rod 8, and the driving rod 8 drives the driving gear 12 to mesh with the runner 6 The tooth slot 11 provided on the gasket engages. At this time, the rotation of the runner 6 drives the sealing baffle 7 to rotate and cover the passage opening of the cut-off valve 2 to prevent the gas from continuing to circulate.

As shown in Figures 1 to 3, further, the transmission component is dynamically connected with the crown gear 13, and the transmission component includes a transmission rod 9 and gears fixed at both ends of the transmission rod 9. The gear at one end of the transmission rod 9 meshes with the crown gear 13 , and the gear at the other end meshes with the tooth plate 10, the tooth plate 10 is fixed to the lower end of the indicator rod 5, the indicator rod 5 moves vertically upward and penetrates the rubber seal block 1 and the top cover 3, and the rubber seal block 1 moves and seals Runner 6 outer wall.

The implementation principle of a fire alarm gas cutoff linkage device in this embodiment is as follows: the motor 4 is electrically connected to the indoor fire sensor.
