Description

Technical Field

[0001] The present invention relates to the technical field of alarms, and in particular to an integrated storage warehouse multi-level joint defense alarm device. Background Art

[0002] As an important storage facility, storage warehouses store a large amount of materials and goods, which may contain some flammable items, such as chemicals, paper, plastic products, etc. Once these items catch fire, the fire spreads rapidly. The alarm device can detect the early signs of fire in time, such as smoke, abnormal temperature, etc., and issue an alarm in time to remind the staff and the fire department to take immediate action to prevent the fire from spreading.

[0003] Traditional fire alarm systems usually use a single type of sensor, such as smoke sensors, infrared sensors or temperature sensors. These systems have certain limitations when detecting fires and are easily interfered by environmental factors, resulting in false alarms or missed alarms. For example, when a single infrared sensor is used, the infrared sensor mainly detects heat sources, but in addition to flames, there are many other heat sources (such as electrical equipment, direct sunlight, etc.) that also generate heat. In order to improve the detection accuracy, infrared sensors are usually designed to be very sensitive, so that an alarm will be triggered when any temperature abnormality is detected. Although high sensitivity increases the detection speed, it also increases the probability of false alarms. In addition, changes in ambient temperature may also cause false alarms of infrared sensors, especially in environments with higher temperatures, where the sensor may misjudge it as a fire. For another example, when a single smoke sensor is used, the smoke generated in the early stage of the fire is less and the diffusion speed is slower, which is not enough to trigger the alarm threshold of the smoke sensor. By the time the smoke sensor detects the smoke, the fire may have spread to an irreversible level.

[0004] In order to solve the above-mentioned problems of false alarm and delayed alarm, the present invention proposes an integrated storage warehouse multi-level joint defense alarm device. Summary of the invention

DETAILED DESCRIPTION

[0034] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0035] Embodiment 1: An integrated storage warehouse multi-level joint defense alarm device, such as Figure 1-Figure 5As shown, it includes a slide rail 101, which is installed on the ceiling of the storage bin, and the length of the slide rail 101 is equal to the length of the storage bin ceiling, a motor 102 is fixedly connected to the right side of the slide rail 101, a screw rod 103 is rotatably connected between the left and right sides of the slide rail 101, the screw rod 103 is connected to the output shaft of the motor 102, a slider 104 is threadedly connected to the screw 103, the slider 104 is slidably connected to the slide rail 101, a smoke sensor 105 is fixedly connected to the left side of the bottom of the slider 104, the smoke sensor 105 is electrically connected to the motor 102 through the control module, and an infrared sensor 106 is fixedly connected to the right side of the bottom of the slider 104, and the infrared sensor 106 is connected to the The slider 104 is electrically connected to the motor 102 through the control module, an alarm 1061 is fixedly connected to the right end of the slide rail 101, and the smoke sensor 105 is electrically connected to the alarm 1061 through the control module. When a fire occurs, the alarm 1061 sends an alarm signal. The left part of the slider 104 is fixedly connected to an air duct 107 symmetrically distributed along the front and rear sides of the slider 104. The air duct 107 is used to guide the hot air flow to the smoke sensor 105. A fan 108 is fixedly connected to the air duct 107. The infrared sensor 106 is electrically connected to the fan 108 through the control module. The air duct 107 is provided with a plurality of evenly distributed air holes 109, so that the hot air flow enters the air duct 107 evenly.

[0036] The device is installed on the ceiling of the storage bin, and the motor 102 is controlled to start continuously. The output shaft of the motor 102 drives the screw 103 to rotate, thereby driving the slider 104 to move to the left on the slide rail 101, and then driving the smoke sensor 105, the infrared sensor 106, the alarm 1061 and the air duct 107 to move to the left as a whole. The air duct 107 drives the fan 108 to move to the left together. When the slider 104 moves to the left to the leftmost side of the slide rail 101, the output shaft of the motor 102 drives the screw 103 to reverse, so that the slider 104, the smoke sensor 105, the infrared sensor 106, the alarm 1061, the air duct 107 and the fan 108 move to the right as a whole to the rightmost side of the slide rail 101, and the above operation is repeated.

[0037] During the above-mentioned movement process, when the infrared sensor 106 detects a heat source, the infrared sensor 106 controls the motor 102 to pause through the control module, and controls the fan 108 to start. The fan 108 guides the airflow at the heat source into the air duct 107 through the air guide hole 109, thereby guiding the smoke sensor 105. If the smoke sensor 105 detects the smoke content, the smoke sensor 105 controls the alarm 1061 to start through the control module. In this way, the effect of timely and accurate fire alarm is achieved, avoiding false alarms or delayed alarms. If the smoke sensor 105 does not detect the smoke content, the smoke sensor 105 controls the motor 102 to continue to start through the control module, and controls the fan 108 to turn off.

[0038] Embodiment 2: Based on embodiment 1, Figure 3 and Figure 6 As shown, it also includes a cylinder 201, which is fixed to the slider 104, the infrared sensor 106 is electrically connected to the cylinder 201 through the control module, the smoke sensor 105 is electrically connected to the cylinder 201 through the control module, the telescopic end of the cylinder 201 is rotatably connected to the first connecting rod 202, the slider 104 is connected to the first cover plate 203 through a rotating shaft, the first cover plate 203 is used to block the smoke sensor 105, the rotating shaft of the first cover plate 203 is rotatably connected to the first connecting rod 202, and the first cover plate 203 is set to a fireproof material.

[0039] In the above process, when the infrared sensor 106 detects a heat source, the infrared sensor 106 simultaneously controls the telescopic end of the cylinder 201 to shorten through the control module. The telescopic end of the cylinder 201 drives the first cover plate 203 to swing downward through the first connecting rod 202, so that the first cover plate 203 does not block the smoke sensor 105, thereby enabling the smoke sensor 105 to detect smoke.

[0040] If the smoke sensor 105 does not detect the smoke content, the smoke sensor 105 controls the telescopic end of the cylinder 201 to extend through the control module, and the telescopic end of the cylinder 201 drives the first cover plate 203 to swing upward through the first connecting rod 202, so that the first cover plate 203 blocks the smoke sensor 105 to prevent the smoke sensor 105 from entering with dust, thereby avoiding affecting the detection accuracy of the smoke sensor 105.

[0041] If the smoke sensor 105 detects the smoke content, the smoke sensor 105 will still control the telescopic end of the cylinder 201 to extend through the control module, so that the first cover plate 203 blocks the smoke sensor 105 to prevent the heat source from spreading to the smoke sensor 105 and burning it.

[0042] like Figure 7 and Figure 8 As shown, it also includes a second connecting rod 301 symmetrically distributed on both sides of the rotation axis of the first cover plate 203, the second connecting rod 301 is rotationally connected to the rotation axis of the first cover plate 203, and the outer part of the air guide tube 107 is rotationally connected with a rotating ring 302, the rotating ring 302 is used to block the air guide hole 109, and the rotating ring 302 is rotationally connected to the adjacent second connecting rod 301.

[0043] When the first cover plate 203 swings downward to open, the first cover plate 203 drives the rotating ring 302 to rotate relative to the air duct 107 through the second connecting rod 301, so that the rotating ring 302 does not block the air duct 109, and the detection of the smoke sensor 105 is not affected.

[0044] When the first cover plate 203 is swung upward and closed, the first cover plate 203 drives the rotating ring 302 to rotate in the opposite direction relative to the air guide tube 107 through the second connecting rod 301, so that the rotating ring 302 blocks the air guide hole 109, preventing dust from entering the smoke sensor 105 through the air guide hole 109 during the left and right movement, thereby further avoiding affecting the detection accuracy of the smoke sensor 105.

[0045] like Figure 9-11 As shown, it also includes a fixed block 401, which is fixedly connected to the slider 104, paraffin is stored in the liquid storage cylinder 404, an elastic telescopic rod 402 is fixedly connected to the fixed block 401, and the telescopic end of the elastic telescopic rod 402 is fixedly connected to the second cover plate 403, the second cover plate 403 is used to block the infrared sensor 106, the second cover plate 403 is set to a fireproof material, the second cover plate 403 is slidably connected to the slider 104, the front right side of the slider 104 is fixedly connected to the liquid storage cylinder 404, the liquid storage cylinder 404 is slidably connected to the limiting rod 405 along the up and down directions, the liquid storage cylinder 404 and the limiting rod 405 constitute a piston-cylinder structure, and the limiting rod 405 is clamped with the second cover plate 403.

[0046] When the heat source spreads to the vicinity of the liquid storage cylinder 404, causing the paraffin in the liquid storage cylinder 404 to expand, the limit rod 405 is squeezed upward by the expanded paraffin until the limit rod 405 no longer blocks the second cover plate 403. At this time, the elastic telescopic rod 402 in the stretched state is reset to drive the second cover plate 403 to slide backward to block the infrared sensor 106, separating the heat source from the infrared sensor 106 to prevent the heat source from burning the infrared sensor 106. At the same time, after the fire is extinguished, the second cover plate 403 covers the infrared sensor 106 to warn the staff not to forget to open the second cover plate 403 to inspect and handle the infrared sensor 106.

[0047] Embodiment 3: Based on embodiment 2, Fig.12 As shown, a fixing frame 501 is also included. The fixing frame 501 is fixedly connected to the bottom right end of the slide rail 101 . A sponge 502 is fixedly connected to the left side of the fixing frame 501 . The sponge 502 is used to wipe the infrared sensor 106 .

[0048] Each time the slider 104 drives the infrared sensor 106 to move rightward to the rightmost end, the sponge 502 will automatically wipe the infrared sensor 106 each time to ensure that the surface of the infrared sensor 106 is clean and tidy, and to prevent debris from affecting the accuracy of its detection.
