Description

Technical Field

[0001] The present invention relates to the technical field of fire alarms, and in particular to an interference-proof fire alarm monitoring device. Background Art

[0002] Fire monitoring systems play an important role in industries, forests, and urban security. However, fire monitoring devices in outdoor environments often face problems such as dust interference, limited monitoring range, and false flame detection, which affect the reliability and accuracy of the system.

[0003] Currently, when traditional fire monitoring devices are used outdoors, dust easily accumulates on the lenses of the monitoring probes, blurring the monitoring images and affecting fire identification efficiency. Although some devices utilize manual cleaning or fixed automatic cleaning mechanisms, these devices suffer from insufficient cleaning frequency, poor cleaning effectiveness, or reliance on external energy sources. Furthermore, existing monitoring equipment typically has a fixed viewing angle and a limited monitoring range. This makes it difficult to dynamically adjust the monitoring position, especially when monitoring wildfires, hindering the timeliness of early fire warnings. Summary of the Invention

[0004] The present invention aims to address the existing problem of dust accumulation on the lenses of monitoring probes, resulting in blurred images and poor fire identification. While some devices employ manual cleaning or fixed automatic cleaning mechanisms, these systems suffer from insufficient cleaning frequency, poor cleaning effectiveness, or reliance on external energy sources. Furthermore, existing monitoring equipment typically has a fixed viewing angle and a limited monitoring range. This makes it difficult to dynamically adjust the monitoring position, particularly during field fire monitoring, hindering the timeliness of early fire warnings.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: an interference-proof fire alarm monitoring device, comprising: a rear plate, a limiting long rod is fixedly installed on the inner wall of the rear plate, a slider is slidably connected to the outer surface of the limiting long rod, a cylinder is fixedly installed on one side of the slider, a motor is fixedly installed on one side of the slider, a monitor is fixedly installed on the output end of the motor, an infrared flame sensor is fixedly installed on the top of the monitor, an alarm is fixedly installed on the top of the monitor, two horizontal bars are fixedly installed on one side of the monitor, and a slide groove is provided on one side of each of the two horizontal bars.

[0006] The technical effect of adopting the above-mentioned further scheme is: the rear plate is installed to the wall by screws so that the monitor can monitor the area, especially when monitoring outdoors, the motor is started by an external power supply to drive the monitor to rotate at an angle, which can increase the monitoring range when the monitor is monitoring. At the same time, when the entire device is monitoring the fire area in the wild, the cylinder is started by an external power supply, and the cylinder pushes the slider to slide on the outer surface of the limit rod. At this time, the monitor can be moved horizontally. At this time, the monitor will not be fixed in a certain position for monitoring, but can move horizontally. At this time, the monitoring range is wider. After the fire is monitored, the alarm will sound an alarm after the monitor shoots and monitors to inform that a fire has occurred. The infrared flame sensor is a key component for detecting flames in the fire alarm system. It has a certain degree of anti-interference by detecting the specific infrared radiation emitted by the flame.

[0007] As a preferred embodiment, two thin rods are fixedly installed on one side of the monitor, and the outer surfaces of the two thin rods are slidably connected with moving blocks, and the bottoms of the two moving blocks are fixedly installed with electric push rods, and the bottoms of the two electric push rods are fixedly installed with clamping block 1, and the sides of the two moving blocks close to their bottoms are fixedly installed with clamping block 2, and the insides of the two slide grooves are rollingly connected with rollers, and one side of the two rollers is provided with a cleaning brush, and two springs are fixedly installed on one side of the cleaning brush, and two dampers are fixedly installed on one side of the cleaning brush.

[0008] The technical effect of adopting the above-mentioned further scheme is: by starting the electric push rod to drive the clamping block 1 to move upward, the mounting block can be removed from the relative surfaces of the clamping block 2 and the clamping block 1, and the cleaning brush can be removed and installed and replaced, so that the replaced cleaning brush can clean the dust on the monitor lens more cleanly.

[0009] As a preferred embodiment, one end of the two dampers is fixedly installed with a mounting block, and the two mounting blocks are located at the bottom of the two clamping blocks. The side of the monitor close to its bottom is rotatably connected to a rotating rod three, and the outer surface of the rotating rod three is fixedly sleeved with a take-up roller. A fan is fixedly installed at one end of the rotating rod three, and one side of the monitor is rotatably connected to a rotating rod two.

[0010] The technical effect of adopting the above-mentioned further scheme is: pulling the movable block to slide on the outer surface of the thin rod, and at the same time driving the roller to roll inside the slide groove, so that the cleaning brush moves on the lens of the monitoring probe of the monitor to clean the dust. By setting the damper and the spring, the cleaning brush can fit more closely to the surface of the monitor, so that the cleaning effect is better.

[0011] As a preferred embodiment, one end of the rotating rod 2 is fixedly installed with a guide wheel 2, one side of one of the moving blocks is fixedly connected to a wire rope, the wire rope is located on the outer surface of the guide wheel 2, the wire rope is movably sleeved on the outer surface of the take-up roller, and the other side of the monitor is rotatably connected to the rotating rod 1, and one end of the rotating rod 1 is fixedly installed with a guide wheel 1.

[0012] The technical effect of adopting the above further scheme is: when the wind blows outdoors, the fan will rotate, and the fan will drive the rotating rod three to rotate. At this time, the rotating rod three drives the winding roller on its outer surface to rotate and reel in the wire rope. At this time, the movable block can be pulled to slide on the outer surface of the thin rod.

[0013] As a preferred embodiment, the steel wire rope is located on the outer surface of the guide wheel 1, and a counterweight is fixedly installed on the other end of the steel wire rope.

[0014] The technical effect of adopting the above-mentioned further scheme is: when there is no wind after a gust of wind, the moving block is pulled to the opposite side of the fan by the wire rope under the action of the gravity of the counterweight block. At this time, the cleaning brush can clean the surface of the monitor again, so that the cleaning brush will not be located in the middle of the monitor to affect the shooting.

[0015] Compared with the prior art, the advantages and positive effects of the present invention are: 1. In the embodiment of the present invention, when the monitor is monitoring, the quality of monitoring is affected by the large amount of dust on the outdoor surface. When the wind blows outdoors, the fan will be blown to rotate. At this time, the fan drives the rotating rod three to rotate. At this time, the rotating rod three drives the wire roller on its outer surface to rotate and reel in the wire rope. At this time, the movable block can be pulled to slide on the outer surface of the thin rod, and at the same time, the roller is driven to roll inside the slide groove, so that the cleaning brush moves on the lens of the monitoring probe of the monitor to clean the dust. By arranging a damper and a spring, the cleaning brush is more closely attached to the surface of the monitor, so that the cleaning effect is better. At the same time, when the movable block slides to the side close to the fan, when the wind does not blow after a gust of wind, the movable block is pulled to the opposite side of the fan by the wire rope under the action of the gravity of the counterweight block. At this time, the cleaning brush can clean the surface of the monitor again.

[0016] 2. In the embodiment of the present invention, the rear plate is mounted to the wall by screws so that the monitor can monitor the area, especially when monitoring outdoors. The motor is started by an external power supply to drive the monitor to rotate at an angle, which can increase the monitoring range when the monitor is monitoring. At the same time, when the entire device is monitoring the fire area in the wild, the cylinder is started by an external power supply, and the cylinder pushes the slider to slide on the outer surface of the limit rod. At this time, the monitor can move horizontally. At this time, the monitor will not be fixed in a certain position for monitoring, but can move horizontally. At this time, the monitoring range is wider. After monitoring the fire, the alarm will sound an alarm after the monitor shoots and monitors to inform that a fire has occurred. The infrared flame sensor is a key component for detecting flames in the fire alarm system. It has a certain degree of anti-interference by detecting the specific infrared radiation emitted by the flame.

[0017] 3. In this embodiment of the present invention, guide wheels 1 and 2 are provided to guide the wire rope as it is pulled. Natural wind power can be used to clean the monitor surface, improving efficiency and conserving resources. To facilitate replacement of the cleaning brush after a period of use, the electric push rod is activated to drive clamping block 1 upward. The mounting block can then be removed from the opposing surfaces of clamping block 2 and clamping block 1. The cleaning brush can then be removed and replaced, allowing the replaced brush to more thoroughly clean dust from the monitor lens. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0021] See also Figures 1 to 8, this embodiment provides a technical solution: an anti-interference fire alarm monitoring device, comprising: a rear plate 101, a limited long rod 102 is fixedly installed on the inner wall of the rear plate 101, a slider 104 is slidably connected to the outer surface of the limited long rod 102, a cylinder 103 is fixedly installed on one side of the slider 104, a motor 105 is fixedly installed on one side of the slider 104, a monitor 106 is fixedly installed on the output end of the motor 105, an infrared flame sensor 107 is fixedly installed on the top of the monitor 106, an alarm 108 is fixedly installed on the top of the monitor 106, two horizontal bars 109 are fixedly installed on one side of the two horizontal bars 109, and a slide groove 1091 is opened on one side of the two horizontal bars 109. The rear plate 101 is installed to the wall by screws so that the monitor 106 can monitor the area, especially for outdoor monitoring. When the fire is detected, the motor 105 is started by an external power supply to drive the monitor 106 to rotate at an angle, which can increase the monitoring range when the monitor 106 is monitoring. At the same time, when the entire device is monitoring the fire area in the wild, the cylinder 103 is started by an external power supply, and the cylinder 103 pushes the slider 104 to slide on the outer surface of the limit rod 102. At this time, the monitor 106 can move horizontally. At this time, the monitor 106 will not be fixed at a certain position for monitoring, and can move horizontally. At this time, the monitoring range is wider. At this time, after monitoring the fire, the alarm 108 will sound an alarm to inform that a fire has occurred after the monitor 106 takes pictures and monitors. The infrared flame sensor 107 is a key component for detecting flames in the fire alarm system. It has a certain degree of anti-interference ability by detecting the specific infrared radiation emitted by the flame.

[0022] like Figures 1 to 8 As shown, in one embodiment, two thin rods 115 are fixedly installed on one side of the monitor 106, and the outer surfaces of the two thin rods 115 are slidably connected to the moving blocks 111, and the bottoms of the two moving blocks 111 are fixedly installed with electric push rods 112, and the bottoms of the two electric push rods 112 are fixedly installed with clamping blocks 113. The sides of the two moving blocks 111 near their bottoms are fixedly installed with clamping blocks 2 114, and the interiors of the two slide grooves 1091 are rollingly connected with rollers 117, and the two rollers 117 are fixedly connected to the two slide grooves 1091. A cleaning brush 116 is provided on one side of the cleaning brush 116, and two springs 118 are fixedly installed on one side of the cleaning brush 116. Two dampers 119 are fixedly installed on one side of the cleaning brush 116. By starting the electric push rod 112 to drive the clamping block 113 to move upward, the mounting block 120 can be removed from the relative surfaces of the clamping block 2 114 and the clamping block 1 113. The cleaning brush 116 is disassembled and installed and replaced, so that the replaced cleaning brush 116 can clean the dust on the monitor 106 lens more cleanly.

[0023] like Figures 1 to 8As shown, in one embodiment, one end of the two dampers 119 is fixedly installed with a mounting block 120, and the two mounting blocks 120 are both located at the bottom of the two clamping blocks 113. The monitor 106 is rotatably connected to a rotating rod 3 127 on one side near its bottom. The outer surface of the rotating rod 3 127 is fixedly sleeved with a take-up roller 126, and one end of the rotating rod 3 127 is fixedly installed with a fan 128. One side of the monitor 106 is rotatably connected to a rotating rod 2 125, pulling the moving block 111 to slide on the outer surface of the thin rod 115, and at the same time driving the roller 117 to roll inside the slide groove 1091, so that the cleaning brush 116 moves on the lens of the monitoring probe of the monitor 106 to clean the dust. By arranging the damper 119 and cooperating with the spring 118, the cleaning brush 116 is more closely attached to the surface of the monitor 106, so that the cleaning effect is better.

[0024] like Figures 1 to 8 As shown, in one embodiment, one end of the rotating rod 2 125 is fixedly installed with a guide wheel 2 124, and one side of one moving block 111 is fixedly connected with a wire rope 129, and the wire rope 129 is located on the outer surface of the guide wheel 2 124. The wire rope 129 is movably sleeved on the outer surface of the take-up roller 126, and the other side of the monitor 106 is rotatably connected with the rotating rod 123, and one end of the rotating rod 123 is fixedly installed with a guide wheel 122. When the wind blows outdoors, the fan 128 will be blown to rotate, and at this time the fan 128 drives the rotating rod 3 127 to rotate. At this time, the rotating rod 3 127 drives the take-up roller 126 on its outer surface to rotate and reel in the wire rope 129. At this time, the moving block 111 can be pulled to slide on the outer surface of the thin rod 115.

[0025] like Figures 1 to 8 As shown, in one embodiment, a steel wire rope 129 is located on the outer surface of the guide wheel 122, and a counterweight block 121 is fixedly installed on the other end of the steel wire rope 129. When there is no wind after a gust of wind, the weight of the counterweight block 121 causes the moving block 111 to move to the opposite side of the fan 128 through the steel wire rope 129. At this time, the cleaning brush 116 can clean the surface of the monitor 106 again, so that the cleaning brush 116 will not be located in the middle of the monitor 106 to affect the shooting.

[0026] Working principle: When in use, the rear plate 101 is installed to the wall by screws so that the monitor 106 monitors the area, especially when monitoring outdoors, the motor 105 is started by an external power supply to drive the monitor 106 to rotate at an angle, which can increase the monitoring range when the monitor 106 is monitoring. At the same time, when the entire device is monitoring the fire area in the wild, the cylinder 103 is started by an external power supply, and the cylinder 103 pushes the slider 104 to slide on the outer surface of the limit rod 102. At this time, the monitor 106 can move horizontally. At this time, the monitor 106 will not be fixed in a certain position for monitoring, but can move horizontally. At this time, the monitoring range is wider. After monitoring the fire, the alarm 108 will sound an alarm to inform that a fire has occurred after the monitor 106 takes pictures and monitors. The infrared flame sensor 107 is a key component for detecting flames in the fire alarm system. It has a certain degree of anti-interference by detecting the specific infrared radiation emitted by the flame. When the monitor 106 is monitoring, the dust on the outdoor surface affects the monitoring. When the wind blows outside, the fan 128 will rotate, and the fan 128 will drive the rotating rod 127 to rotate. At this time, the rotating rod 127 drives the take-up roller 126 on its outer surface to rotate and reel in the wire rope 129. At this time, the moving block 111 can be pulled to slide on the outer surface of the thin rod 115, and at the same time drive the roller 117 to roll inside the slide groove 1091, so that the cleaning brush 116 moves on the lens of the monitoring probe of the monitor 106 to clean the dust. By setting the damper 119 and the spring 118 The combination allows the cleaning brush 116 to fit more closely to the surface of the monitor 106, resulting in a better cleaning effect. Furthermore, when the moving block 111 slides to the side close to the fan 128 and no wind blows after a gust of wind, the weight of the counterweight 121 causes the moving block 111 to move to the opposite side of the fan 128 via the steel wire rope 129. At this point, the cleaning brush 116 can clean the surface of the monitor 106 again. The guide wheel 122 and the guide wheel 2 124 can be provided to guide the steel wire rope 129 when it is pulled. The surface of the monitor 106 can be cleaned using natural wind power, thereby improving efficiency and saving resources. In order to facilitate replacement after the cleaning brush 116 has been used for a certain period of time, the electric push rod 112 is started to drive the clamping block 113 to move upward. At this time, the mounting block 120 can be removed from the relative surfaces of the clamping block 2 114 and the clamping block 1 113, and the cleaning brush 116 can be removed and installed and replaced, so that the replaced cleaning brush 116 can clean the dust on the monitor 106 lens more thoroughly.
