[0041] In related technologies, line environment detection devices are usually composed of fire detectors, fire alarms, and controllers. At the early stage of a fire, they can convert physical quantities such as smoke, heat, and flames generated by combustion into electrical signals through fire detectors, which are then transmitted to fire alarms and / or external fire extinguishing devices. At the same time, they notify the entire floor to evacuate in the form of sound or light. The controller records the location and time of the fire, enabling people to detect the fire in a timely manner and take effective measures to extinguish the initial fire, thereby minimizing the loss of life and property caused by the fire. It is a powerful tool for people to fight against fire.

[0042] However, conventional line environment detection devices usually send signals to fire alarms and / or external fire extinguishing devices when any parameter of the smoke concentration or ambient temperature at the detection point reaches a threshold. When a fire occurs in the external environment outside the detection point, the sensor cannot sense it in time, resulting in inaccurate detection data and untimely signal transmission.

[0043] Therefore, the embodiment of the present application provides an environmental line detection device. Through the setting of the present application, the technical problems of inaccurate detection data and untimely alarms of fire alarms on the market are solved.

[0044] in, Figure 1 A schematic structural diagram of a line environment detection device provided in one embodiment of the present application; Figure 2 yes Figure 1 An exploded diagram of a line environment monitoring device is shown. Through the exploded diagram, the installation positions of the mounting shell 101, the temperature sensor 201, the control module 3, the relay signal module 4 and the power-off protection mechanism 5 on the fixing base 1 can be seen.

[0045] The embodiment of the present application provides a line environment detection device, including a fixing base 1 and a detection mechanism 2; the fixing base 1 is provided with a mounting shell 101, the mounting shell 101 is provided with a first mounting cavity 1011, a second mounting cavity 1012 and a third mounting cavity 1013 which are interconnected, the second mounting cavity 1012 is arranged between the first mounting cavity 1011 and the third mounting cavity 1013; the detection mechanism 2 includes a temperature sensor 201, a smoke concentration sensor 202 and a fan 203, the temperature sensor 201 is installed in the first mounting cavity 1011, and the temperature sensor 201 is used to detect the ambient temperature; the smoke concentration sensor 202 is installed in the third mounting cavity 1011. 013, the smoke concentration sensor 202 is used to detect the ambient smoke concentration; the fan 203 is installed in the second installation cavity 1012; the temperature sensor 201 and the smoke concentration sensor 202 are arranged in series with each other; the side wall of the first installation cavity 1011 is provided with a first channel 1014, and the side wall of the second installation cavity 1012 is provided with a second channel; at least a part of the first channel 1014 is provided corresponding to the air inlet end of the fan 203, and at least a part of the second channel is provided corresponding to the air outlet end of the fan 203, or, at least a part of the second channel is provided corresponding to the air inlet end of the fan 203, and at least a part of the first channel 1014 is provided corresponding to the air outlet end of the fan 203.

[0046] The embodiment of the present application provides a line environment detection device. The present application arranges the temperature sensor 201 and the smoke concentration sensor 202 in series, so that a signal is sent to the fire extinguishing device only when the ambient temperature and the smoke concentration meet the fire occurrence conditions at the same time, thereby avoiding the problem of false alarm and improving the accuracy of detection. The present application arranges the first installation cavity 1011, the second installation cavity 1012 and the third installation cavity 1013 to be interconnected, and the temperature sensor 201 is installed in the first installation cavity 1011, the fan 203 is installed in the second installation cavity 1012 and the smoke concentration sensor 202 is installed in the third installation cavity 1013 ... A first channel 1014 is provided on the side wall of the mounting cavity 1011, and a second channel is provided on the side wall of the second mounting cavity 1012. The fan 203 can allow air from the external environment to enter the first mounting cavity 1011 through the first channel 1014, and then pass through the second mounting cavity 1012 and the third mounting cavity 1013 in sequence, and finally flow out through the third channel. Alternatively, the fan 203 can allow air from the external environment to enter the third mounting cavity 1013 through the second channel, and then pass through the second mounting cavity 1012 and the first mounting cavity 1011 in sequence, and finally flow out through the third channel. This allows the circulation of external air, detects air data from the external environment, and improves the accuracy of the detection data. The configuration of the present application improves the accuracy of the detection data.

[0047] In some examples, reference Figure 2 The first installation cavity 1011, the second installation cavity 1012 and the third installation cavity 1013 are arranged in parallel, and the first channel 1014 and the second channel are arranged opposite to each other. Figure 2 The second channel is not shown in the figure, and those skilled in the art will Figure 2 The position of the first channel 1014 can be thought of as the position of the second channel. The present application facilitates the flow of gas between the first installation cavity 1011, the second installation cavity 1012, and the third installation cavity 1013 by arranging the first installation cavity 1011, the second installation cavity 1012, and the third installation cavity 1013 in parallel. Similarly, the present application accelerates the flow rate of gas between the first installation cavity 1011, the second installation cavity 1012, and the third installation cavity 1013 by arranging the first channel 1014 and the second channel relative to each other, thereby allowing a wider range of external air to enter the cavity formed by the installation shell 101, so that the temperature sensor 201 and the smoke concentration sensor 202 can accurately measure the environmental conditions outside the detection point.

[0048] In some examples, reference Figure 2, the first channel 1014 and the second channel are both configured as long strip through holes, and multiple first channels 1014 are evenly arranged along the height direction of the first installation cavity 1011, and multiple second channels are evenly arranged along the height direction of the second installation cavity 1012. The present application further increases the air flow rate in the first installation cavity 1011, the second installation cavity 1012 and the third installation cavity 1013 by configuring the first channel 1014 and the second channel as multiple long strip through holes. On the other hand, it can avoid the first channel 1014 and the second channel having large openings, so that dust enters the cavity surrounded by the installation shell 101 through the first channel 1014 and / or the second channel, causing pollution to the temperature sensor 201, the smoke concentration sensor 202 and the fan 203, and affecting their detection performance. Reference Figure 2 It can be seen that Figure 2 The first channel 1014 is extended along the width direction of the first installation cavity 1011. Of course, those skilled in the art will understand that the first channel 1014 can also be extended along the width direction of the first installation cavity 1011. Similarly, the second channel can be extended along the length direction of the first installation cavity 1011, and the second channel can also be extended along the width direction of the first installation cavity 1011.

[0049] Exemplarily, a first limiting boss is provided in the first installation cavity 1011, and the first limiting boss forms a first limiting space that is mutually compatible with the temperature sensor 201, and a first gas circulation gap is formed between the temperature sensor 201 and the inner wall of the first installation cavity 1011; similarly, a second limiting boss is provided in the second installation cavity 1012, and the second limiting boss forms a second limiting space that is mutually compatible with the fan 203, and a second gas circulation gap is formed between the fan 203 and the inner wall of the second installation cavity 1012; a third limiting boss is provided in the third installation cavity 1013, and the third limiting boss forms a third limiting space that is mutually compatible with the smoke concentration sensor 202, and a third gas circulation gap (not shown) is formed between the smoke concentration sensor 202 and the inner wall of the third installation cavity 1013.

[0050] Exemplarily, the mounting shell 101 is provided with a through hole, and bolts can pass through the through hole to detachably mount the mounting shell 101 on the side wall of the fixing base 1 .

[0051] In some examples, reference Figure 2 and Figure 4 ,in, Figure 4This is a schematic diagram of the circuitry between the temperature sensor 201, the smoke concentration sensor 202, the control module 3, the relay signal module 4, and the power-off protection mechanism 5. The system may further include the control module 3 and the relay signal module 4, with the control module 3 connected to the temperature sensor 201 and the smoke concentration sensor 202, respectively. The temperature sensor 201 outputs a temperature signal to the control module 3, and the smoke concentration sensor 202 outputs a smoke concentration signal to the control module 3. When the temperature value of the temperature signal exceeds a preset temperature value, and the smoke concentration value of the smoke concentration signal exceeds a smoke concentration value, the control module 3 can send a fire extinguishing signal to the relay signal module 4, causing the relay signal module 4 to transmit the fire extinguishing signal to the fire extinguishing device.

[0052] For example, the control module 3 can be configured as a PLC integrated circuit board. In a specific implementation, the fire extinguishing device can be a dry powder fire extinguisher or a fire sprinkler. When the fire extinguishing device corresponding to the detection device receives a fire extinguishing signal, it can spray dry powder or water in a pre-set direction to extinguish the fire. Of course, those skilled in the art will appreciate that multiple fire extinguishing devices can be provided, with multiple fire extinguishing devices spraying dry powder or water in multiple pre-set directions to achieve better fire extinguishing performance.

[0053] For example, an acoustic and optical alarm may be included, which may be arranged on the line or on the housing of the fixing base 1. When the relay module sends a fire extinguishing signal to the fire extinguishing device, it can also send an alarm signal to the acoustic and optical alarm. After receiving the alarm signal, the acoustic and optical alarm can emit a sound, such as a buzzer or siren, and can also emit a light, which can be set to flash, to serve as a warning.

[0054] In some examples, reference Figure 3The invention is a schematic diagram of the structure of the power-off protection mechanism 5, which also includes a power supply and a power-off protection mechanism 5, which are arranged on the fixed seat 1; the power-off protection mechanism 5 includes a connecting block 501, a safety rope 502 and a movable block 503, the connecting block 501 is connected to the power supply, and the connecting block 501 is also provided with a connecting surface; the safety rope 502 is connected to the movable block 503, and the movable block 503 is respectively connected to the detection mechanism 2, the control module 3 and the transfer signal module 4 through the side wall of the fixed seat 1; the movable block 503 is provided with a mating surface, and the safety rope 502 can pass through the connecting surface and be fixed to the outer wall of the connecting block 501 so that the connecting surface and the mating surface abut each other and are energized; when the temperature of the external environment is greater than the preset temperature value, the safety rope 502 falls to separate the mating surface and the connecting surface. The present application uses the setting of the power-off protection mechanism 5 to promptly disconnect the power supply of the detection device in the event of a fire, thereby protecting the detection device and preventing the circuit of the detection device from being damaged, so as to facilitate the reuse of the detection device. Of course, those skilled in the art will understand that a connecting wire is provided on the side wall of the fixing base 1, and the movable block 503 can be connected to a power line, and the power line is respectively connected to the detection mechanism 2, the control module 3, and the relay signal module 4 to realize power supply to the detection mechanism 2, the control module 3, and the relay signal module 4. Of course, those skilled in the art will understand that the safety rope 502 can be set as a material that can withstand high temperatures within 200°C, such as steel wire or copper wire.

[0055] For example, refer to Figure 2 and Figure 3 , further comprising a buffer spring 504, which is disposed on the side of the movable block 503 facing away from the mating surface and is connected to the detection mechanism 2. By providing the buffer spring 504, when the safety rope 502 falls, the movable block 503 suddenly falls under the action of gravity. The provision of the spring can buffer the movable block 503, preventing damage to the movable block 503, thereby providing better protection for the movable block 503.

[0056] For example, refer to Figure 3 As mentioned above, two buffer springs 504 can be arranged in parallel, and the two buffer springs 504 are arranged in parallel along the length direction of the movable block 503.

[0057] In practice, the number of buffer springs 504 is not limited to two. Those skilled in the art will appreciate that multiple buffer springs 504 can be arranged on the sidewalls of the movable block 503 to provide a better cushioning effect. In practice, the buffer springs 504 can also be replaced with a high-temperature-resistant elastic material, such as a thicker cushion. This can, on the one hand, withstand high temperatures and prevent damage during use, while also providing a buffering effect.

[0058] In some examples, the connecting block 501 is provided with a protrusion 5011, and the protrusion 5011 is provided with a first connecting surface 5012 and a second connecting surface 503. The first connecting surface 5012 is a surface next to the protrusion 5011, and the second connecting surface 503 is a surface connecting the protrusion 5011 and the first connecting surface 5012. The movable block 503 is provided with a first mating surface 5031 and a second mating surface 5032. The first mating surface 5031 and the first connecting surface 5012 are mutually adapted, and the second mating surface 5032 and the second connecting surface 503 are mutually adapted. The present application can increase the contact area between the movable block 503 and the connecting block 501 by mutually adapting the first mating surface 5031 and the first connecting surface 5012, and the second mating surface 5032 and the second connecting surface 503, to ensure the circuit connection between the movable block 503 and the connecting block 501 during normal operation. Of course, those skilled in the art will understand that the second connecting surface 503 may be provided with a first electrical connector, and the second mating surface 5032 may be provided with a second electrical connector that is compatible with the first electrical connector, and the movable block 503 and the connecting block 501 are electrically connected through the first electrical connector and the second electrical connector.

[0059] For example, the first connecting surface 5012 is provided with a sliding track 5014, and the first mating surface 5031 is provided with a sliding boss 5033 that is mutually compatible with the sliding track 5014. In the present application, through the provision of the sliding track 5014 and the mutual cooperation between the sliding boss 5033 and the sliding track 5014, when the safety rope 502 falls and the movable block 503 falls, the movable block 503 can slide down along the sliding track 5014, thereby providing a certain buffering effect on the downward movement of the movable block 503.

[0060] In some examples, the safety rope 502 is glued to the outer wall of the connecting block 501 by a fixing glue. Of course, those skilled in the art will understand that the minimum melting temperature of the fixing glue is greater than 200 degrees Celsius to prevent the fixing glue from melting when the ambient temperature is high.

[0061] In some examples, the fixing base 1 is provided with a threaded hole 102, and the fixing base 1 can be detachably mounted on the mounting frame through the threaded hole 102. The present application realizes a detachable connection of the fixing base 1 by providing the fixing base 1 with the threaded hole 102, which facilitates the installation and removal of the detection device.

[0062] In some examples, the detection device works as follows:

[0063] Before use, set the preset temperature value of the temperature sensor 201 and the preset smoke concentration value of the smoke concentration sensor 202 through the control module 3, connect the connecting block 501 to the power supply, connect the movable block 503 to the connecting line, pull the safety rope 502 through the connecting block 501, so that the first connecting surface 5012 and the first mating surface 5031, the second connecting surface 503 and the second mating surface 5032 cooperate with each other, and make the entire circuit in a connected state, and glue the safety rope 502 to the outer wall of the fixing base 1 at the intersection with the outer wall of the fixing base 1 by fixing glue.

[0064] The fan 203 is started to allow air from the external environment to flow between the first channel 1014 , the first installation cavity 1011 , the second installation cavity 1012 , the third installation cavity 1013 and the second channel.

[0065] The temperature sensor 201 outputs a temperature signal to the control module 3, and the smoke concentration sensor 202 outputs a smoke concentration signal to the control module 3.
