Description
Technical Field
[0001] This utility model belongs to the field of imaging technology, specifically relating to an ultraviolet imager. Background Technology
[0002] Ultraviolet (UV) imagers are specialized devices based on the principle of corona discharge detection, primarily used for diagnosing insulation defects in high-voltage power equipment. When the local electric field strength of a charged body exceeds the critical value for air, corona discharge occurs, releasing ultraviolet light. This technology receives the discharge signal through a UV detector, processes it using an image intensifier and narrowband filter, and then superimposes it onto a visible light image to locate the discharge point and assess its intensity. Early UV imagers were limited by sunlight interference and could only be used at night or on cloudy days. Later versions adopted "all-weather blind" filtering technology, enabling all-weather detection. Its development has gone through three generations: the first generation used broadband UV detection, while the second and third generations introduced narrowband filtering and digital image processing, significantly improving the signal-to-noise ratio and detection accuracy. This technology is now widely used in preventative maintenance of power systems, identifying defects such as conductor damage, insulator contamination, and corrosion of metal components, offering the advantages of being non-contact, intuitive, and efficient.
[0003] Chinese Patent Publication No. CN219675281U discloses an ultraviolet imager. When the object being measured is above the line of sight, it is inconvenient to observe the image displayed on the screen. By rotating the light shield and adjusting the angle of the first and second mirrors, the image on the screen is projected onto the mirrors of the light shield, thus allowing observation of the image on the screen. This facilitates the monitoring of the operating status of power equipment. The second mirror bracket can extend outward from the inside of the light shield, further enhancing the light shielding effect and making the image on the second mirror more adaptable to different observation angles. This facilitates the use of the ultraviolet imager and improves the imaging detection efficiency.
[0004] However, the existing flip covers of some ultraviolet imagers only protect the display screen and lack adequate protection for the keyboard. Moreover, the current flip covers are simply rotating structures without any locking mechanism, which makes them prone to opening on their own during carrying or transportation. This could cause accidental key presses or surface scratches, affecting the normal operation and lifespan of the device. Utility Model Content
[0005] To address the problem of the flip cover not being able to lock in the existing technology, this utility model provides an ultraviolet imager that uses a combination of a locking mechanism and a sliding locking mechanism to achieve the effect of locking the flip cover. The specific technical solution is as follows: An ultraviolet imager includes an ultraviolet imager, with a flip cover rotatably connected to the top of the ultraviolet imager. A plug is fixedly installed at the bottom of the flip cover. A slot is provided on the top of the ultraviolet imager, and the plug is adapted to the slot. A locking mechanism is provided on the ultraviolet imager to lock the plug and the slot. Slotted openings are provided on both sides of the flip cover, and sliding locking mechanisms are provided on both sides of the ultraviolet imager, with the sliding locking mechanisms adapted to the slots.
[0006] Preferably, a keyboard is mounted on the top of the ultraviolet imager, and a display screen is mounted on the bottom of the flip cover.
[0007] Preferably, the front of the ultraviolet imager is provided with an SD card interface, an audio interface, and a battery cover.
[0008] Preferably, a protective cover is installed on the outside of the SD card interface, audio interface and battery cover, and a clip is slidably installed on the front side of the ultraviolet imager to fix the protective cover.
[0009] Preferably, a lens protective cover is installed on the lens of the ultraviolet imager.
[0010] Preferably, a lens protective cover is installed on the lens of the ultraviolet imager.
[0011] Preferably, the locking component includes: a sliding groove, a plug rod, a spring, a connecting rod, and a lever. A sliding groove is formed on one inner wall of the slot. A through hole is formed between the sliding groove and the front side of the ultraviolet imager. A plug rod is slidably connected in the sliding groove. A spring is welded between the plug rod and the inner wall of the sliding groove. A connecting rod is installed on the front side of the plug rod. The connecting rod is slidably connected in the through hole. The front end of the connecting rod slidably extends out of the through hole. A lever is fixedly installed on the front end of the connecting rod.
[0012] In addition, the ultraviolet imager in the above-mentioned technical solution provided by this utility model may also have the following features: a slot is provided on one side of the insertion block.
[0013] In the above technical solution, the slot is adapted to the insertion rod.
[0014] The ultraviolet imager of this invention has the following advantages compared with the prior art:
[0015] 1. This ultraviolet imager protects the keyboard by mounting the display screen on the flip cover. When the flip cover is closed on the ultraviolet imager, it covers the keyboard for protection. This avoids the problem of the keyboard being exposed to the outside and susceptible to dust, liquid splashes or physical collisions in traditional designs. It also forms an overall protective structure when the device is not in use, reducing the risk of external environmental corrosion to the operating parts.
[0016] 2. The combination design of the locking and sliding locking components of this ultraviolet imager provides dual protection for the flip cover locking: the locking component can provide initial mechanical engagement at the moment the flip cover closes, quickly fixing the flip cover position and preventing accidental pop-out; while the sliding locking component can further lock the engagement state by manually sliding, so that even when the device is subjected to vibration or bumps, the flip cover can maintain a stable fit with the body, avoiding the loss of protective function due to the failure of a single locking structure.

[0024] The following are specific implementation cases and appendices. Figures 1-6The present invention will be further described below, but it is not limited to these embodiments. The present invention provides a technical solution: an ultraviolet imager, comprising: an ultraviolet imager 1, a flip cover 2 rotatably connected to the top of the ultraviolet imager 1, an insert block 3 fixedly installed at the bottom of the flip cover 2, the insert block 3 being located near the front center of the flip cover 2, a slot 4 being provided on the top of the ultraviolet imager 1, the slot 4 being located at the front center of the ultraviolet imager 1, the insert block 3 being adapted to the slot 4, a locking component 5 being provided on the ultraviolet imager 1, the locking component 5 being used to lock the insert block 3 and the slot 4; strip-shaped openings 6 being provided on both sides of the flip cover 2, the strip-shaped openings 6 being arranged along the front-back direction, the strip-shaped openings 6 being of the same height, and sliding locking components 7 being provided on both sides of the ultraviolet imager 1, the sliding locking components 7 being adapted to the strip-shaped openings 6.
[0025] As a preferred option, the top of the ultraviolet imager 1 is equipped with a keyboard 8, and the bottom of the flip cover 2 is equipped with a display screen 9. The display screen 9 is a high-definition touch LCD screen, and its size is adapted to the internal space of the flip cover 2. When the flip cover 2 is closed, the display screen 9 and the keyboard 8 are in an up-down correspondence, avoiding the keyboard 8 from squeezing the surface of the display screen 9. The keyboard 8 adopts a splash-proof membrane key design, and the key travel is controlled within the range of 0.8-1.2mm, which not only ensures the operation feel but also reduces the probability of accidental touch. Its surface is covered with a 0.2mm thick polyimide wear-resistant coating, which can withstand more than 5 million key operations.
[0026] As a preferred option, the front of the UV imager 1 is equipped with an SD card interface 13, an audio interface 14, and a battery cover 15. The SD card interface 13 supports the UHS-II high-speed transmission protocol and is compatible with SDXC memory cards with a capacity of up to 2TB, meeting the storage needs of the device for long-term continuous UV image capture. The audio interface 14 adopts the 3.5mm TRRS specification, integrating microphone input and headphone output functions, and supports audio signal transmission with a sampling rate of 8kHz-48kHz, facilitating voice annotation or listening to audio prompts during device operation. The battery cover 15 is connected to the main body of the UV imager 1 via spring clips on both sides. The elastic coefficient of the clips is set to 1.2N / mm, and the pressing and opening force is controlled between 3-5N, which not only ensures the stability of the battery cover 15 but also facilitates users to quickly change the battery with one hand. A 0.5mm thick silicone sealing ring is also attached to the inside of the battery cover 15, which can effectively improve the dustproof and waterproof rating of the device to IP54 standard.
[0027] As a preferred option, a protective cover 10 is installed on the outside of the SD card interface 13, audio interface 14 and battery cover 15. A clip 11 is slidably installed on the front side of the ultraviolet imager 1. The clip 11 is used to fix the protective cover 10. The protective cover 10 is made of polycarbonate material injection molding with a thickness of 2mm. The surface is frosted to enhance the grip friction. A fluororubber sealing gasket is embedded in its inner edge. When the protective cover 10 is closed, it can fit tightly with the metal frame around the interface, further improving the dustproof and waterproof performance of the interface area. The clip 11 has an L-shaped structure and slides along the slide rail on the front of the ultraviolet imager 1 via a dovetail groove at the bottom. The inner side of the slide rail is coated with a PTFE lubricating coating, and the top of the clip 11 has anti-slip textures. Users can push it with their thumb to slide it smoothly. A 3mm diameter magnet is installed at its end, which magnetically engages with the iron plate at the corresponding position on the inner side of the protective cover 10, ensuring that the protective cover will not pop open due to accidental contact when closed. The attraction between the magnet and the iron plate has been adjusted to ensure the stability of the protective cover while allowing users to easily push the clip 11 to release it when operating with one hand. To adapt to different usage scenarios, the sliding stroke of the clip 11 is designed to be 15mm. When it is fully pushed to the edge of the protective cover, the horizontal distance between the magnet and the iron plate exceeds 5mm, and the attraction weakens to less than 0.5N. At this time, the protective cover can naturally pop open a gap of about 5mm, making it convenient for users to lift it open.
[0028] As a preferred option, the lens of the ultraviolet imager 1 is further equipped with a lens protective cover 12. The lens protective cover 12 adopts a screw-in design, which precisely matches the M52×0.75 thread at the front end of the lens. The torque when tightening is controlled within the range of 0.8-1.2 N·m, which avoids damage to the threads due to overtightening and prevents the device from loosening itself when shaking. The light-transmitting window of the protective cover 12 is made of 3mm thick optical-grade K9 glass, with a visible light transmittance of ≥92% and an ultraviolet cutoff rate of ≥99.9%, which can effectively block ultraviolet rays from long-term exposure damage to the optical components inside the lens, while not affecting the clarity of visible light imaging. The outer circumferential surface of the protective cover 12 is machined with 6 equally spaced anti-slip grooves, with a groove depth of 1.5mm and a width of 2mm, which makes it easy for users to unscrew when operating with gloves. The grooves are also marked with arrows indicating the tightening direction.
[0029] As a preferred embodiment, the locking component 5 further includes: a slide groove 51, a rod 52, a spring 53, a connecting rod 54, and a lever 55. A slide groove 51 is provided on one inner wall of the slot 4. A through hole is provided between the slide groove 51 and the front side of the ultraviolet imager 1. The rod 52 is slidably connected in the slide groove 51. A spring 53 is welded between the rod 52 and the inner wall of the slide groove 51. A connecting rod 54 is installed on the front side of the rod 52. The connecting rod 54 is slidably connected in the through hole. The front end of the connecting rod 54 extends slidably out of the through hole. A lever 55 is fixedly installed on the front end of the connecting rod 54.
[0030] As a preferred option, the insert block 3 is further provided with a slot 31 on one side, which is adapted to the insert rod 52. When the flip cover 2 is closed, the insert block 3 is inserted into the slot 4, and the insert rod 52, under the elastic force of the spring 53, will automatically insert one end into the slot 31 on the side of the insert block 3, thus achieving the initial locking of the flip cover 2. At this time, the user can move the lever 55 to drive the connecting rod 54 and the insert rod 52 to slide backward along the slide groove 51, so that the insert rod 52 is disengaged from the slot 31, thereby releasing the locking component 5 from the insert block 3, so that the flip cover 2 can be opened for operation. The free length of the spring 53 is set to 25mm, the compressed working length is 18mm, and the elastic restoring force provided is 8-10N, ensuring that the locking force between the insert rod 52 and the slot 31 is stable and reliable.
[0031] As a preferred embodiment, the sliding locking component 7 further includes: a sliding groove 71, an inner slider 72, a screw 73, and a locking button 74. Sliding grooves 71 are installed on both sides of the ultraviolet imager 1. An inner slider 72 is slidably connected within the sliding groove 71. A screw 73 is installed on the inner slider 72 away from the ultraviolet imager 1. The screw 73 is threadedly connected to the locking button 74. The screw 73 is aligned with the slot 6 in the front-to-back direction. When the flip cover 2 is closed, the inner slider 72 can slide forward along the sliding groove 71, allowing the screw 73 to pass through the slot 6. At this time, the locking button 74 is tightened, and its bottom fits tightly against the side of the flip cover 2. The resulting friction further secures the flip cover 2 to the main body of the ultraviolet imager 1. The sliding groove 71 is made of 6061 aluminum alloy profile, and the internal guide rail precision is controlled within the range of 0.02mm / m. Ensure that the inner slider 72 slides smoothly without jamming; the clearance between the inner slider 72 and the slide body 71 is set to 0.05-0.1mm, and the clearance is filled with lithium-based grease, which can reduce the sliding friction coefficient to below 0.08; the screw 73 is made of stainless steel with M5×12 specification, and its thread precision reaches 6g level, forming a precise fit with the internal thread of the locking button 74, and the radial runout during screwing does not exceed 0.1mm; the locking button 74 is made of TPE soft rubber material through secondary injection molding, and the outer soft rubber has a Shore 60A hardness, which not only ensures grip comfort but also increases the friction with the side of the flip cover; a brass nut is embedded inside, and the fit length between the nut and the screw 73 is 8mm, ensuring that the torque during locking is stable between 1.5-2N·m, and avoiding stress cracking at the edge of the strip opening 6 due to overtightening.
[0032] The ultraviolet imager, keyboard, and display screen in this case are existing technologies, and any ultraviolet imager, keyboard, and display screen that meet the requirements of this case are acceptable.
[0033] The specific types or circuit structures of the controllers for the electrical components mentioned in this application, as well as the circuit connection relationships between the electrical components and the accurate coordinated control of multiple power components, are all prior art. Therefore, the above content will not be elaborated upon in this application.
[0034] Working principle: All electrical components mentioned in this application are externally connected to a power supply and control switch during use. After the utility model is installed, first check the installation, fixation, and safety protection of the utility model, and then it can be used. When using, first open the shockproof box, take out the ultraviolet imager 1, place the ultraviolet imager 1 on the bracket and fix it, rotate the locking buttons 74 on both sides to make the locking buttons 74 turn on the screw 73 and disengage from the flip cover 2, and then slide the locking buttons 74 to make the screw 73 disengage from the slot 6. Then slide the lever 55, causing the lever 55 to move the insertion rod 52 via the connecting rod 54, compressing the spring 53 and causing the insertion rod 52 to disengage from the slot 31. When the insertion rod 52 disengages from the slot 31, then open the flip cover 2 and unscrew the lens protective cover 12; then operate the keyboard 8, press and hold the power button for 3 seconds, and the power indicator light will illuminate, indicating that the device is powered on. After powering on, it will automatically enter the preset display screen and operate through the photo and video recording functions. During the imaging process, the ultraviolet imager 1 captures the operation of the device through the internal ultraviolet sensor. The weak ultraviolet signal generated during operation is converted into an electrical signal by a photoelectric conversion module and then transmitted to the image processing unit for optimization processing such as noise reduction, enhancement, and feature extraction. Simultaneously, a visible light camera synchronously acquires ambient visible light images. The image processing unit accurately fuses the ultraviolet signal image and the visible light image to form a superimposed image that includes the location of the ultraviolet discharge and the environmental background, which is then displayed in real time on the display screen 9. During use, if it is necessary to adjust the shooting parameters, the image clarity can be changed by rotating the lens focal length adjustment ring, or by pressing the mode switch button to switch between shooting, recording, and real-time preview modes. When a strong ultraviolet signal is detected, the device's built-in sound alarm will automatically emit a warning sound, and the signal strength indicator in the upper right corner of the display screen 9 will indicate the signal level with different colors to help operators quickly identify the discharge intensity. After shooting, a short press of the power button will save the current image or video file to the built-in storage module. Then, close the lens protective cover 12 and put the ultraviolet imager 1 back into the shockproof box.
