[0027] It is readily understood that, based on the technical solution of this invention, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of the invention. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this invention and should not be considered as the entirety of the invention or as limitations or restrictions on the technical solution of this invention.

[0028] Example 1 According to one embodiment of the present invention, Figures 1-8 The invention illustrates an outdoor security monitoring device that integrates several traditionally independent functional modules, such as thermal management, mechanical cleaning, posture adjustment, and water resource treatment, into a compact, efficient, and self-sustaining organic whole through ingenious flow channel and structural design.

[0029] The central core of the equipment is a component called Box 3-11. In engineering implementation, Box 3-11 is typically made of die-cast aluminum alloy through a precision mold in a single die-casting process. It has a reinforcing rib structure inside to ensure structural strength while achieving lightweight. In scenarios with high corrosion resistance requirements, it can also be manufactured using high-performance engineering plastics such as glass fiber reinforced polycarbonate or polyphenylene sulfide through injection molding. The internal space of Box 3-11 is carefully planned for installing and fixing the most critical electronic components, including but not limited to: a main control printed circuit board integrating an image signal processor, encoder, and network protocol stack; a high-resolution CMOS or CCD image sensor module, which usually has its own lens group containing multiple lenses; an infrared LED light board for nighttime illumination and its photosensitive control circuit; and a 4G / 5G communication module for wireless data transmission or an Ethernet power supply module for wired transmission. The layout of all these electronic components must take into account electromagnetic compatibility and heat dissipation requirements.

[0030] At the front opening of Box 311, Screen 12 is installed by bolts with silicone sealing rings or by ultrasonic welding. Screen 12 is the "eye" of the device to observe the outside world, and its optical performance and physical strength are crucial. It is usually made of ultra-white tempered glass or polycarbonate sheet with high light transmittance and low birefringence through hot bending or CNC precision machining. Its outer surface is usually coated with multiple anti-reflective films to reduce light reflection, and coated with a waterproof, oil-proof, and dustproof nano-level titanium dioxide or silicon dioxide hydrophobic coating to help water droplets roll off. In some high-end applications, the inner surface of Screen 12 may also integrate a transparent conductive film to assist in defogging under certain conditions. However, this invention mainly solves the problem of internal and external temperature difference through the subsequent thermal circulation system, so this film is not necessary.

[0031] The hallmark of this invention is its active thermal energy circulation system, which does not simply heat the equipment locally, but instead constructs a "heat distribution network" covering the critical surfaces of the equipment.

[0032] A cover component called Shell 1 is fitted over the outside of Box 3 11 with a certain gap. The material of Shell 1 is preferably aluminum alloy or copper alloy with good thermal conductivity. The distance between its inner wall and the outer wall of Box 3 11 is precisely controlled between 3mm and 8mm to form an annular sandwich flow channel. This gap ensures that hot water has enough space to flow and maximizes the heat exchange area. The outer surface of Shell 1 is usually anodized or sprayed with outdoor-grade anti-corrosion paint to enhance its weather resistance.

[0033] The power source of the system is a water pump 26, which is preferably a miniature, low-noise, long-life magnetically driven centrifugal pump or diaphragm pump. The use of magnetic drive can achieve a completely dynamic seal, which fundamentally eliminates the risk of leakage. The rated flow and head of the water pump 26 need to be accurately calculated and selected based on the flow resistance and heat load of the entire circulation system.

[0034] The inlet of the water pump 26 is connected to the water collection unit of the system through pipe 27. The surface of the housing 1 is provided with plate 12, and its outlet is connected to the water inlet on plate 12 through pipe 9. Pipes 9, 27, 10, and 24 are all made of flexible, high-temperature resistant, and aging-resistant silicone tubing or Teflon hose. The pipe joints are fastened with stainless steel hose clamps or quick-connect sealing joints to ensure that they can remain sealed under long-term vibration.

[0035] When the temperature is low, the heater 28 located in box 5 25 is powered on to preheat the small amount of water remaining in the system. After about 30 seconds, the water pump 26 is started. The water pump 26 pumps hot water into the interlayer flow channel between shell 1 and box 3 11. The hot water does not flow in a straight line in this flow channel. In order to prolong the heat exchange time and uniformity, guide fins or spiral flow channels can be designed on the inner wall of shell 1 or the outer wall of box 3 11 to force the hot water to move forward in a spiral in the form of turbulence. The flowing hot water is like a "warm water blanket" to directly insulate box 3 11, which contains precision electronic components, and ensure that its internal temperature is always higher than the dew point. This fundamentally eliminates the phenomenon of condensation and fogging on the inner surface of screen 2 caused by excessively low internal temperature or excessive internal and external temperature difference. The heat carried by the hot water is efficiently conducted to its outer surface through the metal shell of shell 1, which increases the average temperature of the entire equipment shell, so that snowflakes falling on the equipment cannot accumulate but melt immediately.

[0036] After the initial heat exchange is completed, the hot water, which has cooled down, is introduced into the interior of frame 3 through groove 13 set on frame 3. Frame 3 is an annular frame fixed to the edge of screen 2. Its function is not only to fix screen 3, but more importantly, it is designed with annular flow channels with a rectangular cross-section. Hot water enters this annular flow channel from groove 13 and flows along the four sides of screen 2. Since frame 3 is usually also made of metal and is in close contact with the edge of screen 2, heat can be efficiently conducted to the entire area of ​​screen 2. This way of conducting heat from the edge to the center can raise the surface temperature of screen 2 very evenly and avoid local condensation areas where the center is hot and the edge is cold or vice versa, thereby achieving rapid and uniform defrosting.

[0037] Finally, hot water flows from frame 3 into box 4, which is located at the front of the device. Box 4 can be regarded as the outer shell of the device's "head". It also has a cavity inside for hot water to flow. The hot water releases its remaining heat here to keep box 4 itself and the cleaning mechanism inside it warm, ensuring that the entire monitoring head is in a relatively constant temperature environment.

[0038] Example 2 According to one embodiment of the present invention, Figures 1-8 As shown, in order to remove melted water, residual stains or thin layers of snow that have not been completely melted from the surface of Screen 2, the present invention integrates an active cleaning mechanism. The core challenge of this mechanism is how to isolate the drive unit from the aquatic environment.

[0039] The solution is to embed a completely independent, sealed box 4 18 inside box 4. Box 4 18 is usually made of engineering plastic. Its mounting interface with box 4, as well as all wire holes and shaft holes, are dynamically and statically sealed with O-rings or rubber oil seals. Inside box 4 18, motor 19 is installed. This motor is preferably a DC brushless motor with a reduction gearbox, because it has the advantages of high torque, long life and precise control. The output shaft of motor 19 extends out of box 4 18 through a radial sealed bearing.

[0040] The motor shaft extending from box 418 is connected to rod 5, which is a swing arm. Motor 19 drives it to swing back and forth within a certain angle. At the end of the swing arm, plate 6 is installed through a universal ball joint or flexible connector. This type of structure is simple and suitable for spherical or curved screens 2.

[0041] Plate 6, or cleaning blade, is a vulnerable part that directly contacts the surface of Screen 2. It is usually molded from highly weather-resistant silicone rubber or thermoplastic polyurethane material. Its wiping edge is designed to perfectly fit the curved surface of Screen 2 with a specific arc and has multiple lips to ensure effective removal of liquid at any angle. To further enhance the cleaning effect, microfiber strips can sometimes be embedded inside Plate 6.

[0042] A key design element is the continuous warm water wetting of plate 6. Hot water inside shell 1 enters frame 3 through channel 13. The hot water entering frame 3 is diverted by plate 6 17, flowing along plate 6 17 to the space between plate 5 16 and frame 3. Since plate 5 16 is vertically positioned and one end of plate 4 15 is attached to the surface of frame 3, the water flows downwards along plate 5 16. When plate 6 moves to the edge of frame 3, it presses against plate 4 15, causing plate 4 15 to deform. The end of plate 4 15 furthest from plate 5 16 is deformed. 5. Once the scraper detaches from frame 3, the water drains out and comes into contact with plate 6, increasing the surface temperature of plate 6. Plate 6, carrying hot water, rubs against the surface of screen 2, scraping away the ice crystals on the surface of screen 2. The warm water forms a lubricating film between plate 6 and screen 2, greatly reducing the friction and wear of the scraper and extending its service life. In severe cold, dry rubber scrapers will harden and become brittle, easily tearing, while continuous wetting keeps them soft and elastic, leaving a thin film of hot water instead of cold water. This film, supported by subsequent heat cycles, is not prone to refreezing.

[0043] Example 3 According to one embodiment of the present invention, Figures 1-8 As shown, in order to meet different monitoring needs and environmental conditions, the present invention integrates an electric pitch adjustment mechanism.

[0044] The core load-bearing structure of the mechanism is frame 21 and frame 33. Frame 21 has a groove 22 on its surface. Frame 21 and frame 33 are rotatably connected. Frame 33 has a protrusion on its surface. The protrusion is rotatably connected to groove 22. The lower end of frame 323 is fixed to frame 8. Frame 8 is a fixed base for connecting the equipment to the external mounting surface.

[0045] A middle plate is provided between Box 4 (18) and Box 1 (4), and the surface of the middle plate is grooved for the movement of the push rod 20.

[0046] The mechanism is driven by a push rod 20 installed inside the sealed box 18. The push rod 20 is preferably a DC electric push rod. Its cylinder end is hinged to a specially reinforced support on the inner wall of the box 18 by a pin, and its push rod end extends out of the box 18 by a ball joint bearing and is hinged to a protruding support arm in the middle of the frame 23.

[0047] Its working principle is as follows: When it is necessary to change the monitoring angle, the control system sends a command to the push rod 20. The push rod of the push rod 20 extends outward. Since the cylinder end of the push rod is fixed on the box 1 4, the force of its extension will act on the support arm of the frame 3 23. This force will generate a torque, which will force the angle between the frame 2 21 and the frame 3 23 to increase. Since the frame 1 8 is fixed, the entire box 1 4 will rotate upward around the hinge point of the frame 2 21 and the frame 3 23 to achieve rotation. Since the power part of the push rod 20 is set inside the box 4 18, the push rod 20 is avoided from being affected by the external cold air.

[0048] Example 4 According to one embodiment of the present invention, Figures 1-10 As shown, one of the most striking features of this invention is its recycling of water resources. The cooling water that has undergone heat exchange and flows out from box 4 carries impurities such as dust and leaf fragments washed off the equipment surface and is introduced into box 7 through pipe 10. Box 7 is the "kidney" of the entire system, which undertakes the functions of collection, sedimentation, filtration and temporary storage.

[0049] Box 2 (7) is installed at the bottom of the lower-positioned frame 1 (8), utilizing gravity to assist in water collection. Water first enters a buffer sedimentation chamber formed by plate 7 (30) and box 2 (7). Plate 7 (30) is an inclined guide plate, and water flows downwards along it to the space between plate 9 (33) and box 2 (7). Plate 9 (33) is a removable filter plate, and its groove 4 (34) is actually a dense filter hole or an embedded stainless steel filter screen. The mesh size of the filter screen can be selected according to the actual environment, usually between 50 and 100 mesh, which is sufficient to intercept most suspended solids. For easy maintenance, plate 9 (33) can be fixed to box 2 (7) with clips or screws, and can be removed for cleaning or replacement periodically. Water flows through groove 4 (34). The filtered water enters the space between plate 8 (31) and plate 7 (30). The filtered impurities slowly settle and accumulate at the bottom between plate 9 (33) and box 2 (7). The relatively clean water that has been filtered enters the interior of box 5 (25) through pipe 3 (24). Box 5 (25) is equipped with a heater 28, which is usually a stainless steel armored electric heating tube. Its power is determined according to the surface area of ​​the equipment, the target ambient temperature, and the required ice melting speed. The electric heating tube is directly immersed in the water flowing through box 5 (25), resulting in extremely high thermal efficiency. Box 5 (25) has a bend structure. When water from the left side enters box 5 (25), the water level inside box 5 (25) increases. The heated water from the right side of box 5 (25) enters box 6 (32) through trough 3 (29).

[0050] The outer side of box 6 32 is equipped with thermal insulation material to reduce the temperature loss of the water inside box 6 32. The water inside box 6 32 is drawn out from pipe 4 27 by water pump 26 and pumped into shell 1 through pipe 1 9, starting a new round of heat cycle. Thus, a complete closed-loop system of "use-collection-filtration-heating-reuse" is formed. This system minimizes the dependence on external water sources and can work normally in arid areas. Moreover, since the heat is recycled internally, compared with the traditional method of electric heating film directly radiating heat to the outside, its heat loss is smaller and the energy efficiency is significantly improved.

[0051] Impurities accumulate between plate 9 33 and box 2 7. When too many impurities accumulate, rotate column 1 37. When column 1 37 rotates, plate 11 38 detaches from frame 2 35, and plate 10 36 detaches from frame 2 35. Then frame 2 35 leaks out, and the impurities can be discharged from the gaps on the surface of frame 2 35.

[0052] The efficiency of heat transfer by flowing hot water is far higher than that of static air heating or radiant heating. It is fast, uniform, and has no dead corners. By continuously insulating the core of the equipment, the physical basis for condensation on the inner wall is eliminated. The drive part is sealed, the scraper is continuously wetted, the working environment is mild, the failure rate is low, and the closed-loop water circulation and intermittent working mode minimize heat loss. It is particularly suitable for power supply by green energy such as solar energy. It does not rely on external water sources, has its own water treatment system, and can work stably for a long time in various harsh environments.

[0053] Working Principle: When the air temperature is low, the heater 28 located in box 5 25 is powered on to preheat the small amount of water remaining in the system. After about 30 seconds, the water pump 26 is started, pumping hot water into the interlayer flow channel between shell 1 and box 3 11. The hot water does not flow in a straight line in this flow channel. To prolong the heat exchange time and ensure uniformity, guide fins or spiral flow channels can be designed on the inner wall of shell 1 or the outer wall of box 3 11, forcing the hot water to move forward in a spiral in a turbulent manner. The flowing hot water acts like a "warm blanket," directly insulating box 3 11, which contains precision electronic components, ensuring that its internal temperature is always higher than the dew point. This fundamentally eliminates the phenomenon of condensation and fogging on the inner surface of screen 2 caused by excessively low internal temperature or excessive temperature difference between the inside and outside. The heat carried by the hot water is efficiently conducted to its outer surface through the metal shell of shell 1, raising the average temperature of the entire equipment shell. This prevents snowflakes falling on the equipment from accumulating and instead melts immediately. After completing the initial heat exchange, the hot water, whose temperature has dropped slightly, flows through... The slot 13 on frame 3 is introduced into the interior of frame 3. Frame 3 is an annular frame fixed to the edge of screen 2. Its function is not only to fix screen 2, but more importantly, it is designed with an annular flow channel with a rectangular cross-section. Hot water enters this annular flow channel from slot 13 and flows along the four sides of screen 2. Since frame 3 is usually also made of metal and is in close contact with the edge of screen 2, heat can be efficiently conducted to the entire area of ​​screen 2. This way of conducting heat from the edge to the center can raise the surface temperature of screen 2 very evenly, avoiding local condensation areas where the center is hot and the edge is cold or vice versa. This achieves fast and uniform defrosting. Finally, hot water flows from frame 3 into box 4 at the front of the device. Box 4 can be regarded as the outer shell of the device's "head". It also has a cavity inside for hot water to flow. The hot water releases the remaining heat here to keep box 4 itself and the cleaning mechanism inside it warm, ensuring that the entire monitoring head is in a relatively constant temperature environment.

[0054] Water inside box 4 flows through pipe 10 into box 7. Box 7 is installed at the bottom of the lower frame 8, utilizing gravity to assist water collection. The water first enters a buffer sedimentation chamber formed by plate 30 and box 7. Plate 30 is an inclined guide plate, and the water flows downwards along it to the space between plate 33 and box 7. Plate 33 is a removable filter plate, and its groove 34 is actually a dense filter hole or an embedded stainless steel filter screen. The mesh size of the filter screen can be selected according to the actual environment, usually between 50 and 100 mesh, which is sufficient to intercept most suspended solids. For easy maintenance, plate 33 can be fixed to box 7 with clips or screws, and can be removed for cleaning periodically. Water is filtered through trough 4 34 and enters the space between plate 8 31 and plate 7 30. The filtered impurities slowly settle and accumulate at the bottom between plate 9 33 and box 2 7. The relatively clean water that has been filtered enters the interior of box 5 25 through pipe 3 24. Box 5 25 is equipped with a heater 28, which is usually a stainless steel armored electric heating tube. Its power is determined according to the surface area of ​​the equipment, the target ambient temperature, and the required ice melting speed. The electric heating tube is directly immersed in the water flowing through box 5 25, resulting in extremely high thermal efficiency. Box 5 25 has a bend structure. When water from the left side enters box 5 25, the water level inside box 5 25 increases. The heated water from the right side of box 5 25 enters box 6 32 through trough 3 29.

[0055] The outer side of box 6 32 is equipped with thermal insulation material to reduce the temperature loss of the water inside box 6 32. The water inside box 6 32 is drawn out from pipe 4 27 by water pump 26 and pumped into shell 1 through pipe 1 9, starting a new round of heat cycle. Thus, a complete closed-loop system of "use-collection-filtration-heating-reuse" is formed. This system minimizes the dependence on external water sources and can work normally in arid areas. Moreover, since the heat is recycled internally, compared with the traditional method of electric heating film directly radiating heat to the outside, its heat loss is smaller and the energy efficiency is significantly improved.

[0056] Impurities accumulate between plate 9 33 and box 2 7. When too many impurities accumulate, rotate column 1 37. When column 1 37 rotates, plate 11 38 detaches from frame 2 35, and plate 10 36 detaches from frame 2 35. Then frame 2 35 leaks out, and the impurities can be discharged from the gaps on the surface of frame 2 35.

[0057] Hot water inside shell 1 enters frame 3 through channel 13. The hot water entering frame 3 is diverted by plate 17. The hot water flows along plate 17 to the space between plate 16 and frame 3. Since plate 16 is vertically positioned and one end of plate 15 is attached to the surface of frame 3, the water flows downwards along plate 16. When plate 16 moves to the edge of frame 3, it presses against plate 15, causing plate 15 to deform. The end of plate 15 away from plate 16 is deformed, causing plate 15 to detach from frame 3, and the water is discharged. When in contact with plate 6, the surface temperature of plate 6 increases. Plate 6, carrying hot water, rubs against the surface of screen 2, scraping away the ice crystals on the surface of screen 2. The warm water forms a lubricating film between plate 6 and screen 2, which greatly reduces the friction and wear of the scraper and extends its service life. In severe cold, dry rubber scrapers will harden and become brittle, and are easy to tear. However, continuous wetting keeps them soft and elastic, leaving a thin film of hot water instead of cold water. This film is not easy to refreeze under the support of subsequent heat cycles.

[0058] When the monitoring angle needs to be changed, the control system sends a command to push rod 20, and the push rod of push rod 20 extends outward. Since the cylinder end of push rod is fixed on box 1 4, the force of its extension will act on the support arm of frame 3 23. This force will generate a torque, forcing the included angle between frame 2 21 and frame 3 23 to increase. Since frame 1 8 is fixed, the entire box 1 4 will rotate upward around the hinge point of frame 2 21 and frame 3 23, thus achieving rotation. Since the power part of push rod 20 is located inside box 4 18, push rod 20 is prevented from being affected by external cold air.

[0059] The technical scope of this invention is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this invention, and all such modifications and variations should fall within the protection scope of this invention.
