Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. Usually, the components of the embodiments of the present utility model described and illustrated in the accompanying drawings here can be arranged and designed in various different configurations.

[0021] Embodiment 1:

[0022] Please refer to Figure 1 , the present utility model provides a disposable forest fire detector, including a detection device and a signal transceiver device. The detection device is used to detect the occurrence of a fire and send out a signal. The signal transceiver device is used to receive the signal sent by the detection device and send it to a remote terminal.

[0023] The detection device includes a triggering device, a sound - emitting device and an energy - storage device. The triggering device is connected to the energy - storage device, and the sound - emitting device is connected to the energy - storage device. The triggering device is used to trigger the energy - storage device to release the energy for the sound - emitting device to work.

[0024] Adopting the system provided by the present utility model, mainly including a detection device and a signal transceiver device. The detection device includes a triggering device, a sound - emitting device and an energy - storage device. The triggering device is connected to the energy - storage device, and the sound - emitting cavity is connected to the energy - storage device. The triggering device is used to trigger the energy - storage device to release the energy for the sound - emitting device to work. By using this system, only the sound - emitting device for detecting fires in a large - area forest coverage is needed. After the signal transceiver device receives the signal, it is sent to a remote terminal such as a fire command center, and the entire fire detection can be completed. The sound - emitting device in this solution is small in volume, light in weight, low in price and environmentally friendly, without the need to lay expensive smoke detectors or flame detectors.

[0025] In addition, the signal transceiver device includes a sound - signal receiver, a signal processor and a transmitter unit. The sound - signal receiver is electrically connected to the signal processor, and the transmitter unit is electrically connected to the signal processor.

[0026] Of course, the output antenna that should be set can also be set, as well as other devices such as microphones, radio frequency antennas, and radio frequency amplifiers that help the signal transceiver device transmit and receive signals.

[0027] Secondly, in a detection device that requires electrical energy, a mobile power source can be set. The mobile power source can be charged by solar energy and does not need to be replaced frequently.

[0028] Embodiment 2:

[0029] Please refer to Figure 1-2 , on the basis of Embodiment 1, an exemplary implementation manner of the present invention is provided. Specifically, the triggering device includes a thermosensitive element 103 and a first housing 102. The sound generating device includes a first sound generating cavity 104. The energy storage device includes a gas storage cavity 101. The thermosensitive element 103 is disposed in the first housing 102 and is used to connect the first housing 102 at high temperature. The sound generating cavity is connected to one end of the first housing 102. The gas storage cavity 101 is connected to the outside of the first housing 102 and includes the first sound generating cavity 104 therein.

[0030] Among them, the first housing 102 can be a cylindrical structure that is penetrated front and back. When not in use, the thermosensitive element 103 completely blocks the connection between the front end and the back end of the first housing 102.

[0031] The first sound generating cavity 104 is a structure that can emit sound when gas passes through it. It can directly adopt the conventional structure of the existing technology, and the present invention will not elaborate.

[0032] The first housing 102 is disposed at the air outlet end of the first sound generating cavity 104, and the air inlet end of the first sound generating cavity 104 is located inside the gas storage cavity 101. In this embodiment, the gas storage cavity 101 can be filled with high-pressure gas, such as dry ice. After filling with dry ice, a large amount of carbon dioxide gas is released at room temperature, and pressure is generated due to the blockage of the thermosensitive element 103.

[0033] The thermosensitive element 103 can be a plastic airbag, which softens and breaks at high temperature, releasing the gas in the gas storage cavity 101, so as to achieve the purpose of making the first sound generating cavity 104 emit sound.

[0034] Embodiment 3:

[0035] Please refer to Figure 1 and Figure 3, based on the first embodiment, another exemplary implementation of the present utility model is provided. The triggering device includes a compression spring 202, an impact device, and a second housing 203. The bottom of the second housing 203 is connected to an energy storage device. The second housing 203 includes a placement cavity 201 and a second sound - emitting cavity 204. The placement cavity 201 has a structure with a closed upper end and an open lower end, and the second sound - emitting cavity 204 is a structure that can emit sound when gas passes through it conventionally.

[0036] The compression spring 202 is arranged in the placement cavity 201. One end of it is connected to the top of the placement cavity 201, and the other end is connected to an impact device for triggering the energy storage device. A breakable diaphragm 210 is arranged between the placement cavity 201 and the energy storage device. The diaphragm 210 can be a soft diaphragm 210 made of conventional plastic material, which can maintain the compressed state of the compression spring 202.

[0037] During use, under the influence of high temperature, the diaphragm 210 begins to soften. When it can no longer maintain the compressed state of the compression spring 202, the compression spring 202 releases its elastic force, driving the impact device into the energy storage device to trigger the energy storage device.

[0038] Specifically, the energy storage device includes a third housing 209 and a sodium azide layer 205 arranged in the third housing 209. The sodium azide layer 205 is located at the bottom of the second sound - emitting cavity 204, and the third housing 209 is connected to the second housing 203.

[0039] Sodium azide reacts during impact, generating a large amount of nitrogen gas. The large amount of nitrogen gas passes through the second sound - emitting cavity 204, thereby generating a sound signal.

[0040] In this embodiment, the impact device includes a connecting plate, a connecting shaft 211, and an impact block 207. The impact block 207 is connected to the connecting plate through the connecting shaft 211, and the connecting plate is connected to one end of the compression spring 202.

[0041] The impact block 207 can use ordinary hard solids to generate friction with sodium azide, or can use piezo - electric elements to generate an electric arc to better stimulate sodium azide.

[0042] In addition, a partition 208 is arranged at the bottom of the sodium azide layer 205, and the partition 208 is connected within the third housing 209.

[0043] In addition, to avoid the aging of the diaphragm 210, the diaphragm 210 may not be provided, and instead, a holding device is provided. The holding device includes a holding coil and an iron core. The holding coil is wound around the outside of the iron core, and the iron core is disposed inside the compression spring 202. One end of the iron core is fixedly connected to the top of the placement cavity 201, and the connecting plate is made of metal. When an electric current passes through the coil, a magnetic field is generated, which magnetizes the iron core and adsorbs and holds the connecting plate. After the temperature rises to a certain level, the electromagnetic coil fails, the iron core disengages from the connecting plate, and the elastic force of the compression spring 202 is released.

[0044] During the use of the detection device of the present utility model, the detection device is light in weight and low in cost, and can be airdropped into the forest by a helicopter. The detection device is provided with hooks that allow tree branches to catch and hang on the branches.

[0045] Use a helicopter to scatter these low-cost detection devices over a wide area of the forest to cover all tree areas.

[0046] Install a signal transceiver device (solar power generation) every few kilometers in radius to receive the fire events and locations sent by the thermal detector, and then send the fire information to the control center.

[0047] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
