Description

Technical Field

[0001] This utility model relates to the field of prism device technology, and in particular to a protective mechanism and a bidirectional prism device. Background Technology

[0002] In current electric field monitoring station configurations, video surveillance cameras are widely installed as a key component to ensure real-time monitoring of the station's operational status and its surrounding environment. These cameras are typically connected to an intelligent control terminal that supports camera models from mainstream brands on the market and integrates video information into the monitoring software platform, facilitating unified management and viewing by staff.

[0003] To achieve a wider field of view, prism monitoring devices are typically positioned at the top of high towers. However, while this layout enhances the monitoring range and effectiveness, it also exposes the equipment to more severe natural challenges, such as strong winds and sandstorms. Unfortunately, existing prism monitoring devices generally lack effective protective mechanisms for the prism itself, failing to provide adequate protection under these extreme conditions. Furthermore, due to limitations in installation angle, current prism devices also have certain blind spots, hindering the fulfillment of comprehensive monitoring requirements. Utility Model Content

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0029] Reference Figures 1-4 This embodiment provides a protective mechanism, including a protective unit 1, comprising a base column 11, a support frame 12 disposed at the end axis of the base column 11, a large fan wheel 13 disposed at the axis of the base column 11, a small fan wheel 14 disposed at the axis of the large fan wheel 13, a lifting assembly 15 disposed on one side of the large fan wheel 13, a protective cover 16 disposed on one side of the lifting assembly 15, and a connecting assembly 17 disposed on the lifting assembly 15.

[0030] As an optional embodiment, a motor 111 is provided inside the base column 11;

[0031] Furthermore, the support frame 12 is fixedly connected to the axial end of the bottom column 11.

[0032] In this embodiment, the base column 11 serves as the basic support structure of the entire protective mechanism. It is hollow inside and houses a drive motor 111, which can be a stepper motor or a servo motor, to provide power output. The support frame 12 is fixedly connected to the top of the base column 11 via a central axis, forming a stable fixed platform. The support frame 12 has an overall ring or cross-shaped structure, capable of supporting the large fan wheel 13 and other components above, and allowing it to rotate freely around its central axis.

[0033] It should be noted that the large fan wheel 13 is coaxially mounted on the upper part of the support frame 12, and its axis of rotation coincides with the axis of the base column 11, ensuring the stability and rotational balance of the overall structure. The lower end of the large fan wheel 13 is rotatably connected to the support frame 12 through a bearing structure, allowing it to rotate freely under the drive of wind power or motor 111.

[0034] Meanwhile, the bottom of the large fan wheel 13 is equipped with a transmission gear or pulley structure, which is connected to the output shaft of the motor 111 inside the base column 11, thereby realizing active rotation driven by the motor.

[0035] Preferably, the small fan wheel 14 is embedded at the axis of the large fan wheel 13, and the two are rigidly connected by a linkage shaft or coupling, allowing the small fan wheel 14 to rotate synchronously with the large fan wheel 13. By utilizing the power source of the large fan wheel 13, which is driven by wind or an electric motor, the operation of the small fan wheel 14 can be achieved without the need for an additional independent power system. The blades of the small fan wheel 14 are inclined towards the prism to ensure that air is directionally delivered to the prism surface during rotation, achieving efficient heat dissipation.

[0036] Preferably, the lifting assembly 15 is located on one side of the large fan wheel 13, and preferably adopts a screw-slide structure or a pneumatic lifting column. The protective cover 16 is fixedly installed on the movable end of the lifting assembly 15 via the connecting assembly 17, and moves up and down with the lifting assembly 15. The protective cover 16 has a hemispherical or cylindrical structure, and is preferably made of a high-strength transparent material such as polycarbonate or bulletproof glass, which can effectively block the intrusion of external dust and particles without affecting the normal field of view of the camera. The inner wall of the protective cover 16 can be provided with a heating film or an anti-fog coating to prevent condensation caused by temperature differences from affecting the monitoring effect.

[0037] In summary, this invention achieves lifting control of the protective cover 16 and dynamic heat dissipation management of the prism equipment through the synergistic effect of motor drive and natural wind power. The system can flexibly switch operating modes under different weather conditions, ensuring equipment safety while improving monitoring continuity and reliability.

[0038] Reference Figures 1-4 In some embodiments, the support frame 12 includes a support end 121 fixedly connected to the end of the base column 11, a mounting end 122 protruding from the end of the support end 121, and an extension rod 123 provided on one side of the end of the mounting end 122.

[0039] As an optional embodiment, the lifting assembly 15 includes a connecting rod 151 disposed at the axis of the large fan wheel 13, a rotating member 152 disposed at the axis of the connecting rod 151, and a driven member 153 disposed on one side of the rotating member 152.

[0040] As an optional embodiment, the rotating member 152 includes a first pulley 1521 that is fixedly engaged with the connecting rod 151, and a rotating shaft 1522 protruding from the end of the first pulley 1521;

[0041] The small fan wheel 14 is fixedly attached to the outside of the rotating shaft 1522.

[0042] As an optional embodiment, the driven member 153 includes a timing belt 1531 that is sleeved with the first pulley 1521, a second pulley 1532 disposed on the other side of the timing belt 1531, and a lifting rod 1533 fixedly disposed at the axis of the second pulley 1532.

[0043] As an optional embodiment, the connecting assembly 17 includes a connecting cap 171, a slider 172 protruding from one side of the connecting cap 171, and a connecting block 173 protruding from the other side of the connecting cap 171.

[0044] As an optional embodiment, the extension rod 123 is provided with a sliding groove 1231 through it;

[0045] Furthermore, the slider 172 is limited to sliding within the groove 1231.

[0046] As an optional embodiment, the connecting block 173 is fixedly connected to the end face of the protective cover 16.

[0047] In this embodiment, the support frame 12 includes a support end 121 fixedly connected to the top of the base column 11. The support end 121 serves as the foundation of the entire support structure, and is securely connected to the end of the base column 11 via bolts or welding to ensure the stability of the overall structure. The support end 121 has a U-shaped design, connecting the output end of the motor 111 inside the base column 11 and reserving sufficient installation space for the large fan wheel 13. Both ends of the support end 121 have upwardly protruding mounting ends 122, used to support and carry the small fan wheel 14 and the lifting assembly 15 above.

[0048] Furthermore, an extension rod 123 extends from one side of the mounting end 122, providing guidance and limiting functions for the subsequent connecting assembly 17. A sliding groove 1231 is formed through the extension rod 123, with its axis aligned with the extension direction of the extension rod 123, forming a linear slide rail structure. This structure guides the slider 172 in the connecting assembly 17 to slide within it, thereby achieving lateral movement control.

[0049] Preferably, the lifting assembly 15 is disposed on one side of the large fan wheel 13 and is used to drive the protective cover 16 to move up and down in the vertical direction. Its specific structure is as follows: the connecting rod 151 is vertically disposed at the axis of the large fan wheel 13, serving as the power input end of the lifting assembly 15; the rotating component 152 is installed at the axis of the connecting rod 151 and includes a first pulley 1521 and a rotating shaft 1522.

[0050] The first pulley 1521 is fixedly connected to the connecting rod 151 via a snap-fit ​​structure (such as a keyway) to ensure synchronous rotation. The rotating shaft 1522 extends outward from one end of the first pulley 1521 as a power output component. The small fan wheel 14 is snap-fitted to the outer wall of the rotating shaft 1522 through an inner hole and rotates synchronously with the rotating component 152 to achieve continuous heat dissipation for the prism device. The driven component 153 includes a synchronous belt 1531, a second pulley 1532, and a lifting rod 1533. The synchronous belt 1531 is sleeved between the first pulley 1521 and the second pulley 1532 to achieve synchronous transmission between them. The second pulley 1532 is fixedly installed at the axial position of the lifting rod 1533. When the first pulley 1521 rotates, it drives the second pulley 1532 to rotate, thereby driving the lifting rod 1533 to move up and down, realizing the lifting action of the protective cover 16. The above structure enables the lifting assembly 15 to respond to the active drive of the motor 111, and can also use wind power to drive the large fan wheel 13 to indirectly drive the protective cover 16 to rise and fall, thus having dual power sources and improving the reliability and adaptability of the system.

[0051] Preferably, the connecting component 17 is used to achieve a fixed connection between the lifting component 15 and the protective cover 16, and provides a flexible adjustment function. Its specific structure is as follows: Connecting cap 171: A screw hole is provided in the middle, which can be threaded into the lifting rod 1533, enabling the connecting component 17 to drive the protective cover 16 to rise and fall; Slider 172: Located on one side of the connecting cap 171, its shape matches the slide groove 1231, it is embedded in the slide groove 1231 and can slide along its length, serving as a guide and limiter; Connecting block 173: Located on the other side of the connecting cap 171, it is used for a fixed connection with the end face of the protective cover 16, preferably using a bolt connection or a quick-release buckle structure for easy installation and maintenance. Through the cooperation of the slider 172 and the slide groove 1231 of the extension rod 123, the connecting component 17 can slide freely in the horizontal direction. Combined with the connection relationship between the connecting block 173 and the protective cover 16, the height of the protective cover 16 can be adjusted within a certain range according to actual monitoring needs, effectively eliminating blind spots caused by fixed installation and providing wind protection.

[0052] I. Operating status under normal light wind conditions

[0053] Under normal light wind conditions, since the natural wind force is insufficient to drive the large fan wheel 13 to rotate, the large fan wheel 13 will not rotate on its own and cannot transmit power to the small fan wheel 14 and the lifting assembly 15. At this time, the protective cover 16 is in the lowered state. Through the cooperation between the connecting assembly 17 and the slide groove 1231 of the extension rod 123, the slider 172 can slide freely in the slide groove, allowing the connecting cap 171 to drive the connecting block 173 and the protective cover 16 to make fine adjustments in the horizontal direction, thereby ensuring that the prism equipment is always at the optimal observation angle and achieving monitoring without blind spots. In this state, the motor 111 does not start, the system is in a low-power standby mode, and only maintains basic monitoring functions, which is energy-saving and environmentally friendly.

[0054] II. Emergency Response to Severe Weather Conditions such as Strong Winds or Sandstorms

[0055] When the control system detects severe weather conditions such as strong winds, sandstorms, and high temperatures, it can activate the protection mechanism in the following two ways to work together:

[0056] Manual start-up: The operator can manually start the motor 111 via a remote control terminal; Strong wind drives the large fan wheel 13 to start: After the motor 111 starts, it drives the large fan wheel 13 to rotate. The large fan wheel 13 drives the rotating component 152 to rotate synchronously through the connecting rod 151 at its shaft center. The first pulley 1521 is fixedly engaged with the connecting rod 151 to ensure reliable power transmission; the rotating shaft 1522 rotates together with the first pulley 1521 and outputs power to the small fan wheel 14, which continuously delivers cooling air to the prism surface to prevent the equipment from overheating and being damaged due to high temperature.

[0057] Simultaneously, the first pulley 1521 drives the second pulley 1532 to rotate via the synchronous belt 1531, which in turn drives the lifting rod 1533 to move upward, pushing the connecting cap 171 to rise along the thread of the lifting rod 1533, thereby raising the protective cover 16 to fully cover and protect the prism equipment. This protective cover 16 not only effectively blocks sand and dust particles carried by strong winds but also shields the equipment from direct sunlight, preventing damage from high temperatures or mechanical impacts.

[0058] In addition, when the protective cover 16 is raised, the connecting component 17 can still slide within the slide groove 1231 via the slider 172 to achieve fine-tuning of the angle between the connecting block 173 and the protective cover 16, ensuring that the monitoring angle is not affected and eliminating blind spots.

[0059] III. Recovery Operations After the Severe Weather Ends

[0060] When the severe weather ends, motor 111 reverses its direction, driving the large fan wheel 13 to rotate in reverse. This, in turn, drives the rotating component 152, synchronous belt 1531, and lifting rod 1533 downwards, causing the protective cover 16 to automatically descend to its initial position and resuming the panoramic monitoring mode. At this point, the system re-enters energy-saving standby mode, awaiting the next environmental anomaly.

[0061] In summary, this invention achieves lifting control of the protective cover 16 and dynamic heat dissipation management of the prism equipment through the synergistic effect of motor drive and natural wind power. The system can flexibly switch operating modes under different weather conditions, ensuring equipment safety while improving monitoring continuity and reliability, demonstrating promising engineering application prospects.

[0062] Reference Figures 1-5 This embodiment provides a bidirectional prism device, including a mounting unit 2, a mounting shaft 21, clamping blocks 22 disposed on the upper and lower sides of the mounting shaft 21, and a prism 23 hinged to the inner side of the clamping blocks 22.

[0063] In this embodiment, the mounting shaft 21 serves as the core support structure of the entire mounting unit 2. The mounting shaft 21 can be cylindrical or square in cross-section, with the appropriate shape and size selected based on the actual application scenario. The mounting shaft 21 is mounted on the base via a bottom flange or other fixing method, providing a stable support foundation for the clamping blocks 22 and prisms 23 above. The clamping blocks 22 are located on the upper and lower sides of the mounting shaft 21, used to fix and adjust the position of the prisms 23. Each clamping block 22 is designed with a precise adjustment mechanism, allowing operators to fine-tune the angle and height of the prisms 23 to ensure accurate alignment with the target area. The clamping blocks 22 can be securely connected to the mounting shaft 21 via bolts, clips, or other fasteners, and possess a certain degree of flexibility to accommodate prisms 23 of different specifications. The prism 23 is the core optical element of the bidirectional prism device, responsible for reflecting and refracting light, thereby expanding the monitoring range and improving image quality. The prism 23 is mounted on the inner side of the clamping blocks 22 via a hinge, allowing it to rotate freely within a certain range for multi-angle observation. The hinge points are made of wear-resistant materials (such as bronze or engineering plastics) to ensure long-term stability. Prism 23 has two reflecting surfaces located in different directions, allowing light to enter from two opposite directions and be processed by the prism, enabling bidirectional monitoring.

[0064] During installation, the mounting shaft 21 is first fixed in the predetermined position, and the height and angle of the clamping block 22 are adjusted according to actual needs. Then, the prism 23 is installed on the hinge point of the clamping block 22, and the position of the prism 23 is calibrated by adjusting the screws inside the clamping block 22 to ensure it is in optimal working condition.

[0065] Once the device is in use, light from different directions enters the system through the two reflective surfaces of prism 23. Due to the bidirectional nature of prism 23, it can simultaneously capture light from both the front and rear directions and guide it to the corresponding sensor or camera module for processing. This design not only expands the monitoring range but also improves the system's flexibility and response speed.

[0066] During operation, if it is necessary to change the monitoring direction or adjust the viewing angle, the prism 23 can be repositioned using the adjusting screws on the fine-tuning clamp block 22. Furthermore, since the prism 23 is hinged, it can also be manually rotated when necessary to further optimize the observation results.

[0067] In summary, by introducing a bidirectional prism design, this device can significantly expand the monitoring range without adding extra hardware, making it suitable for scenarios requiring comprehensive monitoring (such as electric field monitoring stations, security monitoring, etc.), reducing blind spots and improving overall monitoring efficiency.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
