Description

Technical Field

[0001] This utility model relates to the field of security patrol technology, specifically to a nighttime data acquisition device for security patrol. Background Technology

[0002] In the security field, patrol inspections are a core component of security prevention, and the comprehensiveness, accuracy, and timeliness of data collection directly determine the effectiveness of security early warnings. Nighttime, due to poor lighting conditions and complex and variable environments such as temperature fluctuations, humidity changes, and dim lighting, becomes a high-risk period for security risks, also presenting numerous technical challenges for patrol inspection data collection.

[0003] Existing nighttime security patrol data acquisition devices have gradually revealed several shortcomings in practical applications. Firstly, regarding angle adjustment, traditional devices mostly employ single-dimensional manual adjustment or simple mechanical transmission structures, resulting in low adjustment precision and cumbersome operation. Furthermore, they cannot flexibly adjust the vertical position according to the height of the patrol target, leading to poor acquisition of details of high-altitude equipment or ground conditions at lower levels, creating blind spots. Insufficient nighttime lighting is a core bottleneck for data acquisition. Existing devices often rely on single infrared supplementary lighting or low-light night vision technology, where the supplementary lighting range does not match the camera's shooting range, easily resulting in localized overexposure or insufficient lighting, leading to low image clarity and loss of detail. Some devices lack a collaborative acquisition mechanism designed for the specific characteristics of nighttime environments, relying solely on cameras for image acquisition, which is insufficient to meet the demand for accurate capture of critical information in complex nighttime scenarios.

[0004] In nighttime inspection scenarios, environmental factors such as sudden temperature drops, increased humidity, and dust accumulation can easily cause internal components to become damp, age, or experience performance degradation, affecting the equipment's lifespan. Existing protective structures are mostly simple sealing designs, lacking targeted integrated solutions for thermal insulation, active heat dissipation, and dust and water protection, making them prone to malfunctions in extreme weather or harsh environments. Furthermore, the equipment has a low level of automation, requiring manual monitoring and adjustment in most cases, which not only increases labor costs but also hinders rapid response to sudden safety anomalies at night. Utility Model Content

[0005] The purpose of this invention is to provide a nighttime data acquisition device for security patrols, in order to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A nighttime data acquisition device for security patrol includes a mounting base; the mounting base has two symmetrically distributed grooves, and a bidirectional screw is installed in each groove. The bidirectional screw is screwed to two oppositely distributed sliders. Circular holes are opened on both sides of the sliders, and guide rods are slidably connected in the circular holes. A support base is fixedly connected to the guide rods, and a movable plate is rotatably connected to the support base. A motor is fixedly connected to the bidirectional screw.

[0007] A further improvement of this utility model is that: a column is provided in the groove, the column is rotatably connected to a mounting platform, the mounting platform has two relatively distributed mounting holes, the mounting holes are rotatably connected to a movable plate, the mounting platform is fixedly connected to a camera mounting platform, and the camera mounting platform is detachably connected to a camera.

[0008] A further improvement of the present invention is that a vertical adjustment component is fixedly installed on the top of the support base. The vertical adjustment component includes a fixed frame, a drive motor and a rotating shaft. The fixed frame is bolted to the support base. A rotating shaft is provided on the upper side of the fixed frame. The rotating shaft is threaded and fixedly connected to the output end of the drive motor.

[0009] A further improvement of this utility model is that: a transparent protective shell is detachably connected to the top of the mounting base, a heat insulation layer is pasted on the inner wall of the transparent protective shell, heat dissipation holes are opened on both sides of the transparent protective shell, and a dustproof net and a miniature cooling fan are installed in the heat dissipation holes; an infrared human body sensor is installed at the bottom of the mounting base, and the infrared human body sensor is electrically connected to the motor.

[0010] A further improvement of this utility model is that an infrared fill light and a low-light night vision device are fixedly installed on the top of the mounting platform. The infrared fill light is arranged around the camera, and the low-light night vision device is electrically connected to the camera.

[0011] A further improvement of this utility model is that a temperature sensor and a humidity sensor are installed on the side of the mounting platform, and the temperature sensor and humidity sensor are electrically connected to the miniature cooling fan and the electric heating element in the heat insulation layer, respectively; a waterproof and dustproof protective cover is fitted on the outside of the camera, and the protective cover is sealed to the mounting platform.

[0012] A further improvement of this utility model lies in that: the mounting base is provided with multiple quick-connect interfaces and switches on its side. The quick-connect interfaces include a power interface, a data transmission interface, and a charging interface. The data transmission interface is electrically connected to the camera, low-light night vision device, temperature sensor, humidity sensor, and infrared human body sensor. A buzzer alarm is also installed on the side of the mounting base, and the buzzer alarm is electrically connected to the infrared human body sensor and the temperature sensor.

[0013] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows: 1. This utility model provides a nighttime data acquisition device for security patrols. Through a coordinated transmission structure of a bidirectional screw, motor, and movable plate, it achieves high-precision adjustment of the camera's horizontal angle. The reverse thread design of the bidirectional screw allows the two sliders to move synchronously towards or away from each other, driving the movable plate to drive the mounting platform to rotate smoothly around the column. Combined with the guide rod's limiting and guiding effect on the sliders, it avoids jamming and offset during adjustment, achieving 360° horizontal coverage without blind spots. Simultaneously, the vertical adjustment component at the top of the support base, driven by a motor to rotate the threaded shaft, can precisely adjust the camera's vertical height or pitch angle, adapting to patrol targets at different heights. Whether it's details of high-altitude equipment or ground conditions at low altitudes, it can clearly capture data, completely eliminating the monitoring blind spots of traditional devices. Furthermore, the self-locking characteristic of the screw thread connection and the stable cooperation of each transmission component ensure a stable structure after adjustment, effectively resisting angle offset caused by environmental vibrations and guaranteeing the consistency of long-term patrol data acquisition.

[0014] 2. This utility model provides a nighttime data acquisition device for security patrols. The device adopts a collaborative acquisition scheme of infrared supplementary lighting and low-light night vision, significantly improving the nighttime data acquisition effect. The infrared supplementary lighting is arranged around the camera, ensuring that the supplementary lighting range is highly matched with the camera's shooting range, avoiding problems such as local overexposure or insufficient supplementary lighting. The low-light night vision device is electrically linked to the camera, enabling the capture of clear image details in extremely low light environments. The combination of the two achieves high-quality data acquisition under different nighttime lighting conditions. Simultaneously, the camera can be detachably connected to the mounting platform, supporting the replacement of cameras with different functions such as high-definition night vision and infrared thermal imaging according to patrol needs, adapting to diverse nighttime patrol scenarios and improving the device's scene adaptability and the targeted nature of data acquisition.

[0015] 3. This utility model provides a nighttime data acquisition device for security patrols. The device features a multi-layered protective structure and intelligent environmental adaptability, effectively improving its adaptability to harsh environments. The transparent protective shell on top of the mounting base provides overall protection. The inner thermal insulation layer, in conjunction with the temperature sensor and electric heating element, automatically activates heating when the temperature drops sharply at night, maintaining a suitable operating temperature inside the device. Miniature cooling fans within the heat dissipation holes on both sides of the transparent protective shell are electrically connected to the temperature sensor, automatically activating heat dissipation at high temperatures, forming an adaptive heat preservation and heat dissipation system. Simultaneously, the waterproof and dustproof protective cover on the outside of the camera is sealed to the mounting platform, and the dustproof mesh within the heat dissipation holes further blocks dust, achieving integrated protection against waterproofing, dust, heat preservation, and heat dissipation, effectively preventing components from becoming damp, aging, or experiencing performance degradation. This comprehensive protective design significantly extends the device's lifespan in complex nighttime environments and reduces maintenance costs. Attached Figure Description

[0018] The present invention will be further described in detail below with reference to embodiments: Example 1 like Figure 1-5 As shown, this utility model provides a nighttime data acquisition device for security patrol, including a mounting base 1; the mounting base 1 is provided with two symmetrically distributed grooves 2, and a bidirectional screw 3 is provided in the grooves 2. The bidirectional screw 3 is screwed to two oppositely distributed sliders 4. Circular holes are opened on both sides of the sliders 4, and guide rods 5 are slidably connected in the circular holes. A support base 6 is fixedly connected to the guide rods 5. A movable plate 7 is rotatably connected to the support base 6. A motor 8 is fixedly connected to the bidirectional screw 3.

[0019] A column rod 9 is provided in the groove 2. The column rod 9 is rotatably connected to a mounting platform 10. The mounting platform 10 has two oppositely distributed mounting holes. The mounting holes are rotatably connected to a movable plate 7. The mounting platform 10 is fixedly connected to a camera mounting platform 11. The camera mounting platform 11 is detachably connected to a camera 12.

[0020] A vertical adjustment assembly is fixedly installed on the top of the support base 6. The vertical adjustment assembly includes a fixed frame 13, a drive motor 14 and a rotating shaft. The fixed frame 13 is bolted to the support base 6. A rotating shaft is provided on the upper side of the fixed frame 13. The rotating shaft is threaded and fixedly connected to the output end of the drive motor 14.

[0021] The device uses a motor 8 to drive a bidirectional screw 3, which in turn drives a slider 4 to move synchronously in the opposite direction along a guide rod 5. This, in turn, pushes a movable plate 7 to rotate a mounting platform 10 around a column rod 9. The two grooves 2 are symmetrically distributed, allowing the corresponding cameras 12 to cover the independent monitoring areas on the left and right sides of the device, respectively. Furthermore, the angle adjustment mechanism driven by the bidirectional screw 3 enables seamless wide-area coverage of both sides. Compared to the single-sided coverage of a single camera 12, this design can simultaneously monitor hidden locations on both sides of the device, such as wall corners, equipment gaps, and passageways, avoiding blind spots caused by limited inspection perspectives. This design is suitable for the "all-area prevention and control" requirements of large-scale inspection scenarios such as parks and substations. The drive motor 14 drives a threaded rotating shaft, enabling vertical lifting and lowering of related components through threaded transmission. This allows for precise control of the vertical height of the camera 12, adapting to inspection targets at different heights. For example, during nighttime inspections, the height of the camera 12 can be adjusted to capture details of equipment at higher locations or ground conditions at lower locations. The horizontal and vertical adjustment mechanisms are independent yet can be linked for control, enabling the camera 12 to perform a composite attitude adjustment of "horizontal tilt + vertical lift". This allows for precise targeting of key targets during nighttime inspections, such as distant equipment and instruments, and concealed intrusion points, thereby improving the targeting and effectiveness of data collection.

[0022] like Figure 1-5 As shown, the threaded transmission of the bidirectional screw 3 and the slider 4, combined with the sliding limit of the guide rod 5, can avoid jamming and offset during the adjustment process, ensuring the repeatability and positioning accuracy of the camera 12 angle adjustment; the rotating connection between the movable plate 7 and the mounting platform 10 and the support base 6 adopts a bearing-type hinge, which reduces the transmission resistance in low temperature and vibration environments at night, and ensures the smoothness and stability of the adjustment action.

[0023] Layered monitoring of "far area + near area" and "high place + low place" can be achieved by using the installation height difference of the double groove 2 or the differentiated configuration of the lens parameters of the camera 12.

[0024] Example 2 like Figure 1-5As shown, a transparent protective shell 15 is detachably connected to the top of the mounting base 1. A heat insulation layer is adhered to the inner wall of the transparent protective shell 15. Heat dissipation holes 16 are provided on both sides of the transparent protective shell 15, and dustproof nets and miniature cooling fans 17 are installed inside the heat dissipation holes 16. An infrared human body sensor is installed at the bottom of the mounting base 1, and the infrared human body sensor is electrically connected to the motor 8. The transparent protective shell 15 is made of a high-transmittance, impact-resistant material, which can isolate rainwater, dew, sand, insects, and other impurities in the nighttime inspection environment, preventing contamination or corrosion of core components such as the camera lens 12 and the adjusting motor. It also prevents hardware damage caused by external impacts, making it suitable for complex outdoor inspection scenarios. The detachable design facilitates cleaning, maintenance, and replacement of internal components, reducing maintenance difficulty. The thermal insulation layer can effectively block heat loss in low-temperature environments at night, preventing camera sensors and motor drivers from starting up or experiencing reduced efficiency due to low temperatures; at the same time, it can resist high-temperature radiation during the day, preventing internal electronic components from aging due to continuous high temperatures, ensuring stable operation of the device in a wide temperature range of -20℃ to 60℃, and improving environmental adaptability.

[0025] The miniature cooling fans 17 on both sides of the transparent protective shell 15 can actively dissipate the heat generated by the internal electronic components, such as the motor and the camera 12 drive module, preventing overheating and shutdown caused by heat accumulation in the enclosed space. This is especially helpful in resolving the conflict between "insulation" and "heat dissipation" in low-temperature environments at night. The dust filter can filter out external sand and dust, preventing them from entering the device through the heat dissipation holes 16 and causing short circuits or mechanical jamming, thus balancing heat dissipation efficiency and equipment cleanliness.

[0026] The infrared human body sensor is electrically connected to motor 8, enabling passive and precise monitoring during nighttime patrols. When the sensor detects a human approaching within its monitoring range, it automatically triggers motor 8 to drive camera 12 to horizontally tilt, aligning the monitoring angle with the target area. When there is no human activity, camera 12 can maintain its default patrol angle or enter a low-power standby state. Compared to the traditional "all-time wide-area scanning" mode, this significantly reduces device power consumption and extends battery life. The core requirement for nighttime security patrols is rapid response to intrusion targets. The sensor can capture human signals immediately and trigger camera 12's angle adjustment, ensuring that camera 12 accurately focuses on the target area and avoids missed detections due to angle deviation. Simultaneously, the linkage adjustment mechanism reduces invalid data collection, improves the efficiency of the backend system in identifying and warning of intrusion targets, and enhances the timeliness of security protection.

[0027] Example 3 like Figure 1-5As shown, an infrared supplementary light 19 and a low-light night vision device 18 are fixedly installed on the top of the mounting platform 10. The infrared supplementary light 19 is arranged around the camera 12, and the low-light night vision device 18 is electrically connected to the camera 12. A temperature sensor 20 and a humidity sensor 21 are installed on the side of the mounting platform 10. The temperature sensor 20 and humidity sensor 21 are electrically connected to the miniature cooling fan 17 and the electric heating element in the thermal insulation layer, respectively. A waterproof and dustproof protective cover 22 is fitted over the camera 12, and the protective cover is sealed to the mounting platform 10. The infrared supplementary light 19 is arranged around the camera 12, which can provide a uniform infrared light source in a completely dark environment at night, supplementing the light required for night vision imaging of the camera 12, avoiding the disadvantage of traditional visible light supplementary lights that expose the location of the device, and adapting to the core requirement of "concealed monitoring" in security patrols. The infrared fill light 19's light coverage area is precisely matched to the field of view of the camera 12, effectively eliminating dark corners and shadows in nighttime imaging and improving the detail recognition of targets such as intruders and equipment defects. This solves the pain point of a single camera 12 being unable to image or producing blurry images in completely dark environments. The low-light night vision device 18 is electrically connected to the camera 12 and can amplify and convert weak natural light into clear electrical signals in extremely low light environments such as starlight and moonlight at night, forming a "low-light + infrared" dual-mode night vision system with the camera 12.

[0028] When the temperature sensor 20 detects that the temperature inside the transparent protective shell 15 is higher than the threshold, such as 45°C, it automatically triggers the micro cooling fan 17 to start, quickly dissipating the heat generated by internal electronic components such as the motor driver and the camera module 12, preventing components from aging or shutting down due to high temperature. When the temperature is lower than the threshold, such as -10°C, it automatically activates the electric heating element in the thermal insulation layer to provide constant temperature protection for the core components, preventing the sensor and motor from starting up or becoming inaccurate due to low temperature, and achieving adaptive operation in a wide temperature range of -25°C to 50°C. The humidity sensor 21 can monitor the humidity inside the transparent protective shell 15 in real time. When the humidity is higher than the threshold, such as 85%RH, it can link the cooling fan to ventilate and dehumidify or trigger the heating element to dehumidify at low temperature, avoiding problems such as short circuits in the internal circuits and fogging of the camera lens caused by dew or rainwater penetration at night. It is especially suitable for outdoor inspection scenarios in rainy and humid areas.

[0029] The waterproof and dustproof protective cover 22 on the outside of the camera 12 is sealed to the mounting platform 10, effectively blocking outdoor pollutants such as rainwater, sand, insects, and corrosive gases, preventing the camera lens from being contaminated or scratched. It also prevents short circuits in the internal circuitry due to water ingress or dust accumulation, achieving an IP65 protection rating or higher, suitable for harsh outdoor inspection environments. The protective cover is made of a high-transmittance, wear-resistant material, ensuring that it does not affect the light transmission of the camera 12 and the infrared supplementary light 19, while also providing a certain degree of impact resistance. Furthermore, the protective cover has a detachable, sealed structure, allowing for quick disassembly for lens cleaning and component replacement, reducing maintenance costs.

[0030] Example 4 like Figure 1-5 As shown, the mounting base 1 has multiple quick-connect interfaces 23 and switches 24 on its side. The quick-connect interfaces 23 include a power interface, a data transmission interface, and a charging interface. The data transmission interface is electrically connected to the camera 12, the low-light night vision device 18, the temperature sensor 20, the humidity sensor 21, and the infrared human body sensor. A buzzer alarm is also installed on the side of the mounting base 1, and the buzzer alarm is electrically connected to the infrared human body sensor and the temperature sensor 20. The power interface, data transmission interface, and charging interface adopt a quick-connect design, allowing for rapid connection of the device to external power supplies, inspection terminals, and charging equipment without complex wiring. This significantly shortens the time required for on-site installation, debugging, and maintenance. For example, replacing the data transmission module only requires plugging and unplugging within 10 seconds, adapting to the "rapid deployment and emergency repair" scenario requirements of security inspection. The data transmission interface integrates the signal transmission of all sensing components, including the camera 12, the low-light night vision device 18, the temperature and humidity sensor 21, and the infrared human body sensor, achieving "one-line multi-transmission." This avoids the problems of loose interfaces and signal interference caused by messy multi-line routing, improving wiring neatness and signal transmission stability.

[0031] When an unauthorized intrusion is detected at night, the buzzer alarm immediately emits a high-decibel alarm, deterring intruders and preventing their entry, while also alerting on-site security personnel to take timely action, thus addressing the traditional security vulnerability of "only background warning, no on-site alert." If the temperature inside the device or in the monitored area exceeds a safety threshold as monitored by temperature sensor 20, the alarm will trigger, promptly alerting maintenance personnel to address overheating issues and prevent damage to core components such as cameras 12 and motors. It can also provide early warnings of fires, electrical overheating, and other safety hazards in external inspection areas, achieving dual early warning for both "device self-protection" and "area security." The buzzer alarm's local alert and remote signal transmission via the data transmission interface are synchronized, enabling a dual response of "on-site deterrence + background alarm": the background system can receive alarm trigger signals through the data interface and simultaneously direct camera 12 to focus on the target area, forming an emergency closed loop of "early warning-location-evidence collection," significantly shortening emergency response time.

[0032] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
