Description

Technical Field

[0001] The invention belongs to the technical field of fire fighting equipment, and in particular relates to a rotary rod type fire detection equipment. Background Art

[0002] At present, fire detection equipment is mainly used for indoor fire detection where important electrical equipment is installed. For example, fire detectors are usually fixed vertically above the equipment bodies such as capacitor banks, grounding transformers, station transformers, substation series reactors, and 10kV busbar bridge span boxes installed indoors to ensure that fires can be detected in time and circuit breakers can be triggered in time to avoid burning of electrical equipment or causing larger fires. Fire detection equipment requires daily maintenance. When a fire detection equipment fails, it needs to be repaired or replaced in time to avoid fires in large electrical equipment and the fire detection equipment cannot automatically alarm and handle the fire.

[0003] However, the maintenance and replacement of traditional fire detectors require the use of a movable ladder. Since equipment such as substation capacitor banks, grounding transformers, station transformers, and transformer series reactors are generally in a live operating state, if the fire detectors vertically above such equipment need to be repaired or replaced, the electrical equipment needs to be powered off. On the one hand, the personal safety of the operator needs to be guaranteed, and on the other hand, the grid output needs to ensure continuous power that meets quality requirements. If the fire detection equipment is repaired or replaced only when the equipment is in a normal scheduled power outage, the fire detection equipment may not be handled in a timely manner, causing fire safety hazards during equipment operation. In addition, due to the limited space directly above the equipment body such as the 10kV busbar bridge overpass box, if the fire detector fault defect vertically above the equipment is to be handled, scaffolding needs to be installed, which is time-consuming and labor-intensive, and there is a risk of falling from high altitude operations. Summary of the invention

[0004] Based on this, it is necessary to provide a rotary rod fire detection device that can freely rotate to change the position of the fire detector to facilitate users to repair or replace the fire detector in order to solve the technical problems in the above-mentioned background technology.

[0005] The present application provides a rotary rod type fire detection device, comprising:

[0006] Fire detectors;

[0007] A suspension rod, one end of which is provided with a rotating portion, and the other end of which is used for fixing;

[0008] A connecting rod, the main body of which is connected to the suspension rod via the rotating portion to form a connection point;

[0009] Wherein, the fire detector is arranged on the surface of the connecting rod away from the connection point, and the rotation of the rotating part drives the connecting rod to rotate to change the position of the fire detector.

[0010] In the above-mentioned rotating rod type fire detection equipment, since a rotating part is provided at one end of the suspension rod, the main body of the connecting rod is connected to the suspension rod via the rotating part to form a connection point, and a fire detector is provided on the surface of the connecting rod away from the connection point, so that the rotating part rotates to drive the connecting rod to rotate to change the position of the fire detector. The rotating part rotates to drive the connecting rod to rotate to move the fire detector out of a narrow space and / or dangerous area, which reduces the difficulty and danger of users repairing or replacing the fire detector, and facilitates users to install and use the fire detection equipment.

[0011] In one embodiment, the rotating part includes a rotating motor, the body of the connecting rod is connected to the rotating shaft of the rotating motor, and the rotating motor rotates to drive the connecting rod to rotate coaxially with the rotating motor. The motor rotates to drive the connecting rod to rotate coaxially with the rotating motor, thereby changing the position of the fire detector arranged on the surface of the connecting rod away from the connection point between the connecting rod and the motor, which is convenient for users to install the rotating rod type fire detection equipment in a safe position, and then control the rotation of the rotating motor to drive the connecting rod to rotate to change the position of the fire detector, so that the fire detector is fixed vertically above the large electrical equipment or in a small space, which reduces the difficulty and danger of users repairing or replacing the fire detector, and facilitates users to install and use the fire detection equipment.

[0012] In one embodiment, the rotary rod type fire detection device further includes a control unit, which is connected to the rotating unit and is used to control the rotating unit to rotate forward, reverse or stop. The control unit controls the rotating unit to rotate forward, reverse or stop to drive the connecting rod to rotate forward, reverse or stop, thereby setting a fixed position of the fire detector, which is convenient for the installation, maintenance and inspection of the rotary rod type fire detection device.

[0013] In one embodiment, the rotary rod type fire detection equipment also includes an operating switch connected to the control unit, and the control unit controls the rotating motor to start rotating based on a trigger start signal sent by the operating switch, and the control unit controls the rotating motor to stop rotating based on a trigger stop signal sent by the operating switch.

[0014] In one embodiment, the rotary rod type fire detection device further comprises a supporting device, the supporting device comprises a fixed rod and a supporting rod, one end of the fixed rod is used for fixing, the other end of the fixed rod is connected to one end of the supporting rod, and the supporting rod is used to carry the connecting rod. In order to increase the area that can be covered by the rotation of the connecting rod in the rotary rod type fire detection device, it is necessary to set a connecting rod with a large length value to move the position of the fire detector. At this time, the connection point between the connecting rod and the rotating part is generally close to one end of the connecting rod, and the fire detector is set at the other end of the connecting rod. The fire detector will be tilted toward the ground together with the connecting rod under the influence of gravity, making it difficult to fix the fire detector in a preset spatial position. By setting a supporting device including a fixed rod and a supporting rod, the supporting device can carry the connecting rod, and the supporting device and the suspension rod can suspend the connecting rod together, avoiding the end of the connecting rod where the fire detector is set to tilt toward the ground due to the influence of gravity, and ensuring the stability of the installation of the rotary rod type fire detection device.

[0015] In one embodiment, the surface of the support rod close to the fixing rod is provided with a groove, and the groove is used to carry the connecting rod. By providing the groove on the surface of the support rod close to the fixing rod, the connecting rod can be placed in the groove to fix the connecting rod.

[0016] In one embodiment, the support rod is arc-shaped, and the support rod and the fixing rod together form a fishhook shape. The connecting rod can be suspended by the fishhook-shaped support device together with the suspension rod, thereby ensuring the accuracy of the position setting of the fire detector set on the surface of the connecting rod. When the position of the fire detector needs to be changed, the position of the fire detector can be changed by simply controlling the rotation of the rotating part in the rotating rod type fire detection device.

[0017] In one embodiment, the fire detector comprises:

[0018] A smoke alarm, used to sound an alarm when the detected smoke concentration value is greater than or equal to a preset concentration threshold; and / or

[0019] The temperature alarm is used to alarm when the detected temperature value is greater than or equal to a preset temperature threshold, and / or the temperature alarm is used to alarm when the detected temperature change rate value is greater than or equal to a preset temperature change rate threshold.

[0020] In the rotary rod fire detection device in the above embodiment, the smoke alarm is set to alarm when the detected smoke concentration value is greater than or equal to the preset concentration threshold; and the temperature alarm is set to alarm when the detected temperature value is greater than or equal to the preset temperature threshold, and the temperature alarm can also be set to alarm when the detected temperature change rate value is greater than or equal to the preset temperature change rate threshold. The smoke alarm and the temperature alarm work together to detect whether a fire has occurred. When the smoke alarm and the temperature alarm alarm at the same time, it indicates that a fire is likely to have occurred.

[0021] In one embodiment, the fire detector comprises:

[0022] Alarm confirmation light, which is used to display an alarm light of a preset color in the event of an alarm; and / or

[0023] The alarm sounder is used to emit a preset alarm sound when an alarm occurs.

[0024] In the rotary rod type fire detection equipment in the above embodiment, by setting an alarm confirmation light in the fire detector to present an alarm light of a preset color when an alarm is triggered, and / or setting an alarm sounder to emit a preset alarm sound when an alarm is triggered, when the detected smoke concentration value is greater than or equal to the preset concentration threshold, or the detected temperature value is greater than or equal to the preset temperature threshold, or the detected temperature change rate value is greater than or equal to the preset temperature change rate threshold, the alarm confirmation light and / or the alarm sounder can promptly emit an alarm light and / or an alarm sound to alert people and draw their attention.

[0025] In one embodiment, the fire detector is a composite smoke and heat fire detector, which is used to determine whether a fire occurs based on the obtained smoke concentration value and temperature value. Compared with using a smoke alarm and a temperature alarm to jointly determine whether a fire occurs, using a composite smoke and heat fire detector can reduce the volume and weight of the fire detector.

[0026] In one embodiment, the composite smoke and heat fire detector comprises:

[0027] Smoke sensor device, used to detect smoke concentration value;

[0028] Semiconductor temperature sensor device, used to detect temperature value;

[0029] The microprocessor is connected to the smoke sensor and the semiconductor temperature sensor respectively, and is used to store and judge the acquired smoke concentration value and temperature value.

[0030] In the rotary rod fire detection device in the above embodiment, by setting a smoke sensor to detect the smoke concentration value, setting a semiconductor temperature sensor to detect the temperature value, the obtained smoke concentration value and the temperature value are stored and judged based on the microprocessor. For example, it can be judged that a fire occurs when the obtained smoke concentration value is greater than or equal to a preset concentration threshold and the obtained temperature value is greater than or equal to a preset temperature threshold, or it can be judged that a fire occurs when the obtained smoke concentration value is greater than or equal to a preset concentration threshold and the obtained temperature change rate value is greater than or equal to a preset temperature change rate threshold.

[0040] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. Preferred embodiments of the present invention are provided in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0042] In the case of using “including”, “having”, and “comprising” described herein, another component may be added unless a clear limiting term such as “only”, “consisting of”, etc. is used. Unless mentioned otherwise, a term in the singular form may include a plural form and should not be understood as being one in number.

[0043] Since the substation capacitor bank, grounding transformer, station transformer, transformer series reactor and other equipment need to be operated under power, if the fire detector equipment failure defect directly above this equipment is to be handled, the equipment needs to be powered off. However, if the equipment is powered off, it is necessary not only to ensure the safety of equipment operation, but also to ensure that the power grid equipment N-1 operates after the equipment is powered off to improve the reliability of power grid operation. If the fire detector is processed while waiting for the approval of the dispatching equipment power outage, the fire detector defect may not be handled in time, causing fire safety hazards in the operation of the equipment. Due to the limited space directly above the equipment body such as the 10kV busbar bridge overpass box, if the fire detector equipment failure defect directly above this equipment is to be handled, scaffolding needs to be set up for processing, which is time-consuming and laborious, and there is a risk of falling from high-altitude operations. Therefore, the present application provides a rotary rod fire detection device, which is convenient for the operator to fix and install the rotary rod fire detection device in a safe and spacious place, and then control the rotation of the rotary rod to drive the fire detector to move to a preset fixed position. When it is necessary to repair or replace a fire detector installed in a small space or a dangerous area, the fire detector can be moved to a spacious and safe area by controlling the rotation of the rotary rod, and then the fire detector can be repaired or replaced to reduce the difficulty and danger of the operator installing, repairing or replacing the fire detector.

[0044] like Figure 1As shown, in one embodiment of the present application, a rotating rod type fire detection device is provided, which includes a fire detector 10, a suspension rod 20 and a connecting rod 30. A rotating portion 21 is provided at one end of the suspension rod 20, and the other end of the suspension rod 20 is used for fixing, for example, the other end of the suspension rod 20 can be fixed to an indoor roof 50; the body of the connecting rod 30 is connected to the suspension rod 30 via the rotating portion 21 and forms a connecting point 22; wherein the fire detector 10 is provided on the surface of the connecting rod 30 away from the connecting point 22, and the rotation of the rotating portion 22 drives the connecting rod 30 to rotate to change the position of the fire detector 10.

[0045] Specifically, in the rotating rod type fire detection device in the above embodiment, a rotating part 22 can be provided at one end of the suspension rod 20, the body of the connecting rod 30 is connected to the suspension rod 30 via the rotating part 22 to form a connection point 22, and a fire detector 10 is provided on the surface of the connecting rod 30 away from the connection point 22, so that the rotating part 22 rotates to drive the connecting rod 30 to rotate to change the position of the fire detector 10. The fire detector 10 can be moved out of a narrow space and / or dangerous area by rotating the rotating part 21 to drive the connecting rod 30 to rotate, which reduces the difficulty and danger of the user to repair or replace the fire detector, and facilitates the user to install and use the fire detection device.

[0046] Further, in a rotary rod type fire detection device provided in one embodiment of the present application, as Figure 2 As shown, the rotating part includes a rotating motor 211, and the body of the connecting rod 30 is connected to the rotating motor 211. The rotating motor 211 rotates to drive the connecting rod 30 to rotate coaxially with the rotating motor 211. The rotating motor 211 rotates to drive the connecting rod 30 to rotate coaxially with the rotating motor 211, thereby changing the position of the fire detector 10 arranged on the surface of the connecting rod 30 away from the connection point 22 between the connecting rod 30 and the rotating motor 211, so that the user can install the rotating rod type fire detection device in a safe position, and then control the rotation of the rotating motor to drive the connecting rod 30 to rotate to change the position of the fire detector 10, so that the fire detector 10 is fixed vertically above the large electrical equipment 40 or in a narrow space area, thereby reducing the difficulty and danger of the user's maintenance or replacement of the fire detector, and facilitating the user's installation and use of the fire detection device.

[0047] Specifically, Figure 2 As shown, a control unit 212 may be provided to be connected to the rotating motor 211. The control unit 212 controls the rotating motor 211 to rotate based on a trigger start signal obtained from the user to drive the connecting rod 30 to rotate so as to change the position of the fire detector 10. When the connecting rod 30 rotates to drive the fire detector 10 to move to a suitable position, the control unit 212 controls the rotating motor 211 to stop rotating based on a trigger stop signal obtained from the user, so that the fire detector 10 stops at a safe position to facilitate the operator to perform maintenance or replacement operations on it.

[0048] Further, in a rotary rod type fire detection device provided in one embodiment of the present application, as Figure 3 As shown, the operation switch 80 may be provided to be connected to the control unit 212, so that the user can send a trigger start signal or a trigger stop signal to the control unit 212 by operating the operation switch 80. The operation switch 80 may be provided in a place that is easily accessible to the user, so that the user can send a trigger start signal or a trigger stop signal to the control unit 212 through the operation switch, so that the control unit 212 controls the rotating motor 211 to rotate with the shaft 2111 as the central axis based on the acquired user's trigger start signal, thereby driving the connecting rod 30 to rotate in a plane parallel to the horizontal plane, and the rotation of the connecting rod 30 drives the fire detector 10 to move. When the fire detector 10 moves to a suitable position, the user can send a trigger stop signal to the control unit 212 through the operation switch, so that the fire detector 10 stops in a safe and spacious position, so that the operator can repair or replace it.

[0049] Specifically, in the rotating rod type fire detection device in the above embodiment, when the operator needs to set the fire detector 10 in a dangerous area and / or an area with a small space, the operator can fix one end of the suspension rod 20 in a safe and spacious area, for example, one end of the suspension rod 20 can be fixed to the indoor roof, and then the operator can send a trigger start signal to the control unit 212 through the touch operation switch 80, so that the control unit 212 controls the rotating motor 211 to rotate to drive the connecting rod 30 to rotate to change the position of the fire detector 10. When the connecting rod 30 rotates to drive the fire detector 10 to move to a suitable position, the control unit 212 controls the rotating motor 211 to stop rotating based on the user's trigger stop signal obtained, so that the fire detector 10 stops in a safe position to facilitate the operator to perform maintenance or replacement operations on it. Similarly, when the user needs to repair or replace the fire detector 10 installed in a dangerous area and / or an area with a small space, the user can send a trigger start signal to the control unit 212 by touching the operation switch 80, so that the control unit 212 controls the rotating motor 211 to rotate to drive the connecting rod 30 to rotate to change the position of the fire detector 10. When the connecting rod 30 rotates to drive the fire detector 10 to a suitable position, the control unit 212 controls the rotating motor 211 to stop rotating based on the user's trigger stop signal, so that the fire detector 10 stops in a safe position to facilitate the operator to repair or replace it.

[0050] Specifically, in the rotary rod type fire detection device in the above embodiment, Figure 3As shown, the operation switch 80 may also be provided with a forward control button and a reverse control button, so that the user can send a forward control trigger signal to the control unit 212 via the forward control button to control the rotating motor 211 to rotate with the shaft 2111 as the rotating axis and drive the fire detector 10 to move. Figure 3 The direction indicated by the middle arrow is the forward direction. The user can send a reverse control trigger signal to the control unit 212 via the reverse control button to control the rotating motor 211 to rotate with the shaft 2111 as the rotating axis and drive the fire detector 10 to move.

[0051] Further, in a rotary rod type fire detection device provided in one embodiment of the present application, as Figure 4 As shown, a support device 70 for carrying the connecting rod 30 can be provided, and the support device 70 includes a fixed rod 71 and a support rod 72. One end of the fixed rod 71 is used for fixing. For example, one end of the fixed rod 71 can be fixed to the indoor roof 50, and the other end of the fixed rod 71 can be connected to one end of the support rod 72. The support rod 72 is used to carry the connecting rod 30. In order to increase the area that can be covered by the rotation of the connecting rod in the rotating rod type fire detection device, a connecting rod with a large length value needs to be provided to move the position of the fire detector. At this time, the connection point between the connecting rod and the rotating part is generally close to one end of the connecting rod, and the fire detector is provided at the other end of the connecting rod. The fire detector will be tilted toward the ground together with the connecting rod under the influence of gravity, making it difficult to fix the fire detector in a preset spatial position. By providing a support device including a fixed rod and a support rod, the support device can carry the connecting rod, and the support device and the suspension rod can suspend the connecting rod together, avoiding the end of the connecting rod provided with the fire detector from tilting toward the ground due to the influence of gravity, and ensuring the stability of the installation of the rotating rod type fire detection device.

[0052] Furthermore, in the rotary rod type fire detection device in the above embodiment, if Figure 4As shown, the support rod 72 is arc-shaped, and the support rod 72 and the fixing rod 71 together form a fishhook shape. The fishhook-shaped support device 70 can be used together with the suspension rod 20 to suspend the connecting rod 30, thereby ensuring the accuracy of the position of the fire detector 10 set on the surface of the connecting rod 30, preventing the fire detector 10 from tilting toward the ground due to the influence of gravity along with the connecting rod 30, and ensuring the stability and safety of the installation of the fire detector 10. When the position of the fire detector needs to be changed, the user can send a trigger start signal to the control unit 212 by touching the operation switch 80, so that the control unit 212 controls the rotating motor 211 to rotate to drive the connecting rod 30 to rotate to change the position of the fire detector 10. When the connecting rod 30 rotates to drive the fire detector 10 to move to a suitable position, the control unit 212 controls the rotating motor 211 to stop rotating based on the user's trigger stop signal obtained, so that the fire detector 10 stops at a safe position, so that the operator can perform maintenance or replacement operations on it.

[0053] Further, in a rotary rod type fire detection device provided in one embodiment of the present application, as Figure 5 As shown, the support device 70 includes a fixing rod 71 and a supporting rod 72, one end of the fixing rod 71 is used for fixing, for example, one end of the fixing rod 71 can be fixed to the indoor roof 50, and the other end of the fixing rod 71 can be connected to one end of the supporting rod 72, and the supporting rod 72 is used to carry the connecting rod 30. A groove 73 is provided on the surface of the supporting rod 72 close to the fixing rod 71, and the groove 73 is used to carry the connecting rod 30. By providing the groove 73 on the surface of the supporting rod 72 close to the fixing rod 71, the connecting rod 30 can be placed in the groove 73 to fix the connecting rod 30.

[0054] Furthermore, if Figure 6 As shown, a groove 73 may be provided on the surface of the support rod 72 close to the fixing rod 71, and the shape and size of the groove 73 may be matched with the shape and size of the connecting rod, so that the groove 73 can play a good fixing role on the connecting rod.

[0055] Furthermore, in a rotary rod fire detection device provided in one embodiment of the present application, the fire detector includes a smoke alarm and / or a temperature alarm. The smoke alarm is used to alarm when the detected smoke concentration value is greater than or equal to a preset concentration threshold; the temperature alarm is used to alarm when the detected temperature value is greater than or equal to a preset temperature threshold, and / or the temperature alarm is used to alarm when the detected temperature change rate value is greater than or equal to a preset temperature change rate threshold. Since a large amount of smoke in the environment will cause the smoke concentration to rise rapidly when a fire occurs, and the fire will cause the ambient temperature at the fire scene to rise rapidly to a very high value, a smoke alarm and a temperature alarm can be set in the fire detector to respectively detect whether the smoke concentration value, temperature value, and / or temperature change rate value exceed the corresponding threshold range to determine whether a fire occurs. In other embodiments of the present application, environmental detection equipment such as humidity alarms and PM2.5 alarms can also be added to the fire detector to comprehensively determine whether a fire occurs by detecting multiple environmental parameter values.

[0056] In the rotary rod fire detection device in the above embodiment, the smoke alarm is set to alarm when the detected smoke concentration value is greater than or equal to the preset concentration threshold; and the temperature alarm is set to alarm when the detected temperature value is greater than or equal to the preset temperature threshold, and the temperature alarm can also be set to alarm when the detected temperature change rate value is greater than or equal to the preset temperature change rate threshold. The smoke alarm and the temperature alarm work together to detect whether a fire has occurred. When the smoke alarm and the temperature alarm alarm at the same time, it indicates that a fire is likely to have occurred.

[0057] Furthermore, in a rotary rod fire detection device provided in one embodiment of the present application, the fire detector includes an alarm confirmation light and / or an alarm sounder, the alarm confirmation light is used to present an alarm light of a preset color when an alarm occurs; the alarm sounder is used to emit a preset alarm sound when an alarm occurs. In other embodiments of the present application, other forms of alarm devices can also be set, for example, the smoke concentration value, temperature value, and / or temperature change rate value collected on site can be sent to the mobile terminal of the relevant staff, and the relevant staff can be prompted to take corresponding treatment measures in time through the mobile terminal to remind the relevant staff to avoid greater losses caused by the fire, while also improving the safety, intelligence and efficiency of on-site monitoring.

[0058] In the rotary rod fire detection equipment in the above embodiment, an alarm confirmation light is set in the fire detector to present an alarm light of a preset color when an alarm is triggered, and / or an alarm sounder is set to emit a preset alarm sound when an alarm is triggered, so that when the detected smoke concentration value is greater than or equal to the preset concentration threshold, or the detected temperature value is greater than or equal to the preset temperature threshold, or the detected temperature change rate value is greater than or equal to the preset temperature change rate threshold, an alarm light and / or an alarm sound are promptly emitted to alert people and draw their attention.

[0059] Further, in a rotary rod type fire detection device provided in one embodiment of the present application, as Figure 7 It is shown that the fire detector can be set as a composite smoke and temperature fire detector, which is used to determine whether a fire has occurred based on the obtained smoke concentration value and temperature value. Compared with the use of smoke alarms and temperature alarms to determine whether a fire has occurred, the use of composite smoke and temperature fire detectors can reduce the volume and weight of fire detectors. Composite smoke and temperature fire detectors not only have the performance of ordinary scattered photoelectric smoke fire detectors, but also have the performance of fixed temperature and differential fixed temperature fire detectors. Since composite smoke and temperature fire detectors have a composite technology of smoke and temperature sensing, composite smoke and temperature fire detectors can detect and alarm the combustion of national standard test fires SH3 (polyurethane plastic fire) and SH4 (n-heptane fire). At the same time, composite smoke and temperature fire detectors can also detect and alarm open flames with obvious temperature rise such as alcohol combustion, expanding the application range of photoelectric smoke detectors.

[0060] Furthermore, in the rotary rod type fire detection device in the above embodiment, Figure 7 As shown, a composite smoke and temperature fire detector can be provided, including a smoke sensor device 11, a semiconductor temperature sensor device 12 and a microprocessor 13. The smoke sensor device 11 is used to detect the smoke concentration value; the semiconductor temperature sensor device 12 is used to detect the temperature value; the smoke sensor device 11 and the semiconductor temperature sensor device 12 are respectively connected to the microprocessor 13, and the microprocessor 13 is used to store and judge the acquired smoke concentration value and the temperature value to judge whether a fire has occurred or a fire may occur.

[0061] Furthermore, in the rotary rod type fire detection device in the above embodiment, an alarm confirmation light and / or an alarm sounder may be provided to promptly emit an alarm light and / or an alarm sound when the detected smoke concentration value is greater than or equal to a preset concentration threshold, or the detected temperature value is greater than or equal to a preset temperature threshold, or the detected temperature change rate value is greater than or equal to a preset temperature change rate threshold. Figure 7It is shown that an alarm confirmation light 14 and an alarm sounder 15 can be respectively connected to the microprocessor 13. When the microprocessor 13 determines that the obtained smoke concentration value is greater than or equal to the preset concentration threshold, or the obtained temperature value is greater than or equal to the preset temperature threshold, or the obtained temperature change rate value is greater than or equal to the preset temperature change rate threshold, the microprocessor 13 promptly controls the alarm confirmation light 14 and the alarm sounder 15 to emit an alarm light and / or an alarm sound to alert people and attract their attention.

[0062] Further, in a rotary rod type fire detection device provided in one embodiment of the present application, as Figure 8 As shown, a signal transmitter 16 can be set to be connected to the microprocessor 13, and the smoke concentration data and temperature data collected by the smoke sensor 11 and the semiconductor temperature sensor 12 can be sent to the mobile terminal of the relevant staff through the signal transmitter 16, and the relevant staff can be prompted through the mobile terminal that a fire has occurred, so as to remind the relevant staff to take corresponding treatment measures in time to avoid greater losses caused by the fire, while also improving the safety, intelligence and efficiency of on-site monitoring.

[0063] In the rotary rod fire detection device in the above embodiment, by setting a smoke sensor to detect the smoke concentration value, setting a semiconductor temperature sensor to detect the temperature value, the obtained smoke concentration value and the temperature value are stored and judged based on the microprocessor. For example, it can be judged that a fire occurs when the obtained smoke concentration value is greater than or equal to a preset concentration threshold and the obtained temperature value is greater than or equal to a preset temperature threshold, or it can be judged that a fire occurs when the obtained smoke concentration value is greater than or equal to a preset concentration threshold and the obtained temperature change rate value is greater than or equal to a preset temperature change rate threshold.

[0064] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0065] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent.
