Description

A monitoring and early warning device for preventing forest fires Technical Field

[0001] This utility model relates to the field of forest fire prevention technology, and more specifically, to a monitoring and early warning device for preventing forest fires. Background Technology

[0002] Forests, as an important component of the Earth's ecosystem, play an irreplaceable role in maintaining ecological balance and regulating climate. Monitoring and early warning devices for forest fire prevention are crucial facilities for achieving early detection and response to fires.

[0003] The prior art announcement CN220569243U discloses a forest fire early warning device. The device uses a camera, a temperature sensor, and a smoke detector to monitor the forest in a timely and effective manner. However, during use, due to the large temperature difference between day and night in the forest environment, when the temperature of the camera lens is lower than the temperature of the surrounding air, water vapor in the air will condense into fog on the lens surface, causing the monitoring image to become blurry. This makes it impossible to capture abnormal situations in the forest in time, thus delaying the opportunity to issue a fire warning. Summary of the Invention

[0004] Based on the aforementioned technical problem that forest temperatures fluctuate significantly between day and night, and that when the lens temperature is lower than the dew point temperature of the surrounding air, moisture in the air will condense into fog on the lens surface, causing the monitoring image to become blurry and making it impossible to capture abnormal situations in the forest in time, thus delaying the timing of fire warnings, this utility model proposes a monitoring and early warning device for preventing forest fires.

[0005] This utility model proposes a monitoring and early warning device for preventing forest fires, which includes a mounting base, a mounting box, a storage box, a balance plate, and a blower heating component.

[0006] The mounting box is fixedly connected to the top of the mounting base, and a monitoring and early warning camera is fixedly installed on the top of the mounting box;

[0007] The storage box is fixedly connected to the front side of the monitoring and early warning camera lens. A rotating shaft is horizontally arranged inside the storage box, and the two ends of the rotating shaft are rotatably connected to the inner wall of the storage box.

[0008] The balance plate is fixedly connected radially along the rotating shaft. The two sides of the balance plate are symmetrically fixedly connected with second fan blades perpendicular to its surface. The outer wall of the second fan blades is fixedly connected with a sponge block. The end of the balance plate away from the rotating shaft is provided with a counterweight block.

[0009] The blower heating component is located inside the mounting box and is used to deliver hot air into the storage box and drive the second fan blade to rotate, thereby causing the sponge block to wipe the surface of the monitoring and early warning camera lens.

[0010] Preferably, a protective cover is fixedly connected to the top of the monitoring and early warning camera, and the two sides of the protective cover are bent downward to form arc-shaped rolled edges.

[0011] Preferably, the monitoring and early warning camera has two support plates fixedly connected to its bottom, and the outer wall of the support plates is fixedly connected to the top of the mounting box.

[0012] Preferably, a filter screen is fixedly connected to the end of the mounting box, and a sealing cover is detachably installed at the open end of the mounting box.

[0013] Preferably, the blower heating assembly includes a base, a stepper motor is fixedly connected to the top of the base, an output shaft is fixedly connected to the output end of the stepper motor, and a first fan blade is fixedly connected to the outer wall of the output shaft.

[0014] Preferably, the blower heating assembly further includes an air guide tube, which is fixed inside the mounting box. The end of the air guide tube is fixedly connected to the air intake grille, and the end of the output shaft passes through the air intake grille and is rotatably connected to it.

[0015] Preferably, an air guide nozzle is fixedly connected to the inner wall of the sealing cover. The air guide nozzle has a conical structure, and an air tube is fixedly connected to the end of the air guide nozzle. The end of the air tube is fixedly connected to the storage box.

[0016] Preferably, the blower heating assembly further includes a heater, the power cord of which is electrically connected to a heating coil, which is located inside the air guide tube.

[0017] The beneficial effects of this utility model, achieved through the above technical solution, are as follows:

[0018] 1. By setting up a storage box, rotating shaft, balance plate, fan blades, sponge block, counterweight, and blower heating component, when the blower heating component is working, hot air blows the fan blades to drive the sponge block to wipe the lens. At the same time, the hot air heats and evaporates the mist, solving the problem of blurry images caused by mist on the lens due to changes in forest ambient temperature. This ensures clear monitoring images and enables the monitoring and early warning camera to capture abnormal situations such as forest fires in a timely and accurate manner, improving the timeliness and accuracy of forest fire monitoring and early warning.

[0019] 2. The conical structure of the air nozzle can converge and accelerate the hot air output from the air tube, so that the hot air is blown more concentratedly onto the fan blades and lens surface inside the storage box. Attached Figure Description

[0025] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] In this utility model, unless otherwise explicitly specified and limited, the term "fixed connection" should be interpreted broadly. For example, "fixed connection" can mean fixed installation, detachable connection, or integral connection; it can mean mechanical connection or electrical connection; it can mean direct connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] As shown in Figures 1 and 4, a monitoring and early warning device for preventing forest fires includes a mounting base 1, a mounting box 2, a storage box 6, a balance plate 20, and a blower heating assembly.

[0028] The mounting box 2 is fixedly connected to the top of the mounting base 1, and a monitoring and early warning camera 4 is fixedly installed on the top of the mounting box 2.

[0029] The storage box 6 is fixedly connected to the front side of the lens of the monitoring and early warning camera 4. A rotating shaft 19 is horizontally arranged inside the storage box 6, and the two ends of the rotating shaft 19 are rotatably connected to the inner wall of the storage box 6.

[0030] The balance plate 20 is radially fixedly connected along the rotating shaft 19. The two sides of the balance plate 20 are symmetrically fixedly connected with second fan blades 21 perpendicular to its plate surface. The outer wall of the second fan blades 21 is fixedly connected with sponge blocks 22. The end of the balance plate 20 away from the rotating shaft 19 is provided with a counterweight block 23.

[0031] The blower heating component is located inside the mounting box 2 and is used to deliver hot air into the storage box 6 and drive the second fan blade 21 to rotate, thereby driving the sponge block 22 to wipe the surface of the lens of the monitoring and early warning camera 4.

[0032] By setting up a storage box 6, a rotating shaft 19, a balance plate 20, a second fan blade 21, a sponge block 22, a counterweight block 23, and a blower heating assembly, when the blower heating assembly is working, hot air blows the second fan blade 21, which in turn drives the sponge block 22 to wipe the lens. At the same time, the hot air heats and evaporates the mist, solving the problem of blurry images caused by mist on the lens due to changes in forest ambient temperature. This ensures clear monitoring images and enables the monitoring and early warning camera 4 to capture abnormal situations such as forest fires in a timely and accurate manner, improving the timeliness and accuracy of forest fire monitoring and early warning.

[0033] In this embodiment, as shown in Figure 1, a protective cover 5 is fixedly connected to the top of the monitoring and early warning camera 4, and the two sides of the protective cover 5 are bent downward to form arc-shaped rolled edges.

[0034] The protective cover 5 can protect the monitoring and early warning camera 4 during daily use, reducing the impact of debris, rain, etc. on the lens.

[0035] In this embodiment, as shown in Figure 1, two support plates 3 are fixedly connected to the bottom of the monitoring and early warning camera 4, and the outer wall of the support plate 3 is fixedly connected to the top of the mounting box 2.

[0036] The support plate 3 securely connects the monitoring and early warning camera 4 to the mounting box 2, enhancing the stability of the monitoring and early warning camera 4 installation.

[0037] In this embodiment, as shown in Figure 2, a filter screen 9 is fixedly connected to the end of the mounting box 2, and a sealing cover 8 is detachably installed at the open end of the mounting box 2.

[0038] The sealing cover 8 facilitates maintenance and repair of the interior of the mounting box 2. After disassembly, it allows for easy inspection and replacement of components such as the blower heating assembly.

[0039] The filter 9 can filter the air entering the installation box 2, preventing dust and other impurities from entering the installation box 2.

[0040] In this embodiment, as shown in Figures 2 and 3, the blower heating assembly includes a base 10, a stepper motor 11 is fixedly connected to the top of the base 10, an output shaft 12 is fixedly connected to the output end of the stepper motor 11, and a first fan blade 13 is fixedly connected to the outer wall of the output shaft 12.

[0041] The stepper motor 11 drives the first fan blade 13 to rotate through the output shaft 12, delivering air evenly and stably into the storage box 6, providing power and hot air for lens defogging.

[0042] In this embodiment, as shown in FIG3, the blower heating assembly further includes an air guide cylinder 14, which is fixed in the mounting box 2. The end of the air guide cylinder 14 is fixedly connected to the air intake grille 15, and the end of the output shaft 12 passes through the air intake grille 15 and is rotatably connected to it.

[0043] In this embodiment, as shown in Figure 2, an air guide nozzle 18 is fixedly connected to the inner wall of the sealing cover 8. The air guide nozzle 18 has a conical structure, and an air pipe 7 is fixedly connected to the end of the air guide nozzle 18. The end of the air pipe 7 is fixedly connected to the storage box 6.

[0044] The conical structure of the air nozzle 18 can converge and accelerate the hot air output from the air tube 14, so that the hot air is blown more concentratedly onto the second fan blade 21 and the lens surface inside the storage box 6.

[0045] In this embodiment, as shown in FIG2, the blower heating assembly further includes a heater 16, and the power cord of the heater 16 is electrically connected to a heating coil 17, which is located inside the air guide tube 14.

[0046] The heating temperature of the heating coil 17 is controlled by the heater 16, so that the air is heated to a suitable temperature. The hot air can not only accelerate the evaporation of fog on the lens surface, but also improve the effect of the sponge block 22 in wiping the lens, further ensuring that the lens surface of the monitoring and early warning camera 4 remains clear.

[0047] Working principle: When fog appears on the lens, the stepper motor 11 is started, and its output end drives the output shaft 12 to rotate. The first fan blade 13 on the output shaft 12 rotates accordingly, drawing outside air into the air guide tube 14 through the air intake grille 15.

[0048] At the same time, the heater 16 heats the heating coil 17 through the power cord, which heats the air entering the air guide cylinder 14 to form hot air. The hot air is delivered to the storage box 6 through the air guide cylinder 14 and the air guide nozzle 18.

[0049] Hot air blows the second fan blade 21 to make it rotate around the shaft 19, and the sponge block 22 fixed on the outer wall of the second fan blade 21 wipes the surface of the lens of the monitoring and early warning camera 4 to dry the mist.

[0050] At the same time, hot air heats the lens, accelerating the evaporation of fog and quickly restoring clarity to the lens surface, ensuring that the monitoring and early warning camera 4 can continuously and clearly capture abnormal situations in the forest.

[0051] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
