Description

Technical Field

[0001] This utility model relates to the field of lighting testing technology, specifically to a device for testing the aging of dock lighting. Background Technology

[0002] As a core hub for cargo loading and unloading and ship berthing, the continuous operation of port facilities places extremely high demands on lighting systems. Port lighting must provide sufficient illumination in low-visibility environments such as nighttime, heavy fog, and heavy rain to ensure the precise and safe operation of hoisting machinery, cargo transfer, and ship berthing and unberthing. The lighting effect directly affects operational efficiency and the safety of personnel and equipment. For example, in container terminal hoisting operations, insufficient brightness or unstable lighting may lead to misalignment of the spreader, causing cargo to fall or equipment to collide. In bulk cargo terminal nighttime loading operations, lighting failure may prevent operators from judging the amount of material loaded, resulting in overloading or uneven loading.

[0003] However, traditional methods for detecting the aging of dock lighting have many drawbacks. Currently, the mainstream detection method relies on manual inspection, where operators observe changes in brightness with the naked eye. This method is greatly affected by subjective judgment and makes it difficult to accurately identify early aging.

[0004] To address the aforementioned issues, we propose a device for detecting the aging of dock lighting fixtures. Utility Model Content

[0005] To address the technical problem that existing methods rely on operators visually observing brightness changes, which are heavily influenced by subjective judgment, this invention provides a device for detecting the aging of dock lighting fixtures.

[0006] This utility model is achieved using the following technical solution: an aging detection device for dock lighting lamps, comprising a detector and a photometer probe. One end of the detector is equipped with a photometer probe, and a flip cover is provided on the outside of the photometer probe. The flip cover is hinged to the surface of the detector. A display screen is provided on the middle surface of the detector. A handle is fixedly connected to the other end of the detector. A fixed frame is fixedly connected to one side of the detector. A high-definition camera is installed inside the fixed frame. One end of the high-definition camera is fixedly connected to a connecting rod. One end of the connecting rod is rotatably connected to the inside of the detector. A toothed ring is fixedly connected to one end of the connecting rod. A limiting toothed groove is machined inside the detector, and the toothed ring is inserted into the limiting toothed groove.

[0007] Preferably, a movable groove is machined on one side of the limiting tooth groove, and the toothed ring is movably connected inside the movable groove.

[0008] Preferably, one end of the limiting tooth groove is machined with a connecting groove, and a first return spring is fixedly connected to the inner wall of one end of the connecting groove. One end of the first return spring is fixedly connected to one side of the tooth ring.

[0009] Preferably, the handle is internally connected to an extension block, the extension block is internally machined with a groove, and the groove is internally connected to a pressure block.

[0010] Preferably, the handle has multiple limiting holes machined on its exterior, and the pressure block is plugged into the inside of the limiting holes.

[0011] Preferably, a second reset spring is provided inside the groove, one end of the second reset spring is fixedly connected to the inner wall of one end of the groove, and the other end of the second reset spring is fixedly connected to the bottom of the pressure block.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In use, the light from the lamp illuminates the silicon photocell through a photometer probe, exciting a photocurrent. After amplification, filtering, and analog-to-digital conversion, the current is converted into an illuminance value by a microprocessor and finally displayed on a screen to determine whether the light is aging. By pulling the connecting rod outward, the connecting rod will cause the toothed ring to move out of the limiting tooth groove. Then, by rotating the connecting rod, the high-definition camera will rotate at a certain angle and be aligned with the lamp. By adjusting the focus of the high-definition camera with a button, the external condition of the lamp can be clearly displayed on the screen, thereby determining whether there is any breakage or aging.

Detailed Implementation

[0018] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0019] Example 1: Please refer to Figure 1 - Figure 3 This embodiment of a dock lighting aging detection device includes a detector 1 and a light metering probe 2. The light metering probe 2 is provided at one end of the detector 1. A flip cover 3 is provided on the outside of the light metering probe 2. The flip cover 3 is hinged to the surface of the detector 1. A display screen 4 is provided on the middle surface of the detector 1. A handle 5 is fixedly connected to the other end of the detector 1. A fixed frame 6 is fixedly connected to one side of the detector 1. A high-definition camera 7 is provided inside the fixed frame 6. A connecting rod 8 is fixedly connected to one end of the high-definition camera 7. One end of the connecting rod 8 is rotatably connected to the inside of the detector 1. A toothed ring 9 is fixedly connected to one end of the connecting rod 8. A limiting toothed groove 11 is machined inside the detector 1. The toothed ring 9 is plugged into the limiting toothed groove 11.

[0020] The working principle of the photometer probe 2 belongs to the existing technology. The core is the coordination of photoelectric conversion and signal processing. It receives light through the photometer probe 2. The core photosensitive element of the silicon photocell inside the probe uses the photoelectric effect to convert light into photocurrent. The stronger the light, the greater the current excited.

[0021] When light enters, the probe's filter filters out non-visible light, and the cosine corrector corrects the influence of the incident angle of the light to ensure accurate measurement. The weak current is amplified by an amplifier and reduced by a filter before being converted into a digital signal by an analog-to-digital converter. Then, the microprocessor converts it into an illuminance value based on the calibration data, and finally displays it on the display screen 4. The whole process realizes the conversion of "light signal → electrical signal → digital signal" to ensure the accuracy of light intensity measurement.

[0022] Secondly, when testing for light aging, first measure and record the initial illuminance of the new lamp under standard conditions; judge the degree of aging by comparing the illuminance values. If the illuminance decreases to less than 70% of the initial value, it is determined that the lamp is aging and needs to be replaced.

[0023] Furthermore, when inspecting the external aging of the dock lighting, hold the handle 5 and pull the connecting rod 8 outward. The connecting rod 8 will drive the toothed ring 9 to move, and the toothed ring 9 will disengage from the inside of the limiting tooth groove 11. Then rotate the connecting rod 8 to make the high-definition camera 7 rotate a certain angle and align it with the lighting. At the same time, the display screen 4 is positioned at an angle that is convenient for the staff to view. The focus of the high-definition camera 7 is adjusted by the button, so that the external condition of the lighting can be clearly displayed on the display screen 4, thereby determining whether there is any breakage or aging.

[0024] Furthermore, a movable groove 12 is machined on one side of the limiting tooth groove 11, and the tooth ring 9 is movably connected inside the movable groove 12. A connecting groove 13 is machined on one end of the limiting tooth groove 11, and a first return spring 14 is fixedly connected to the inner wall of one end of the connecting groove 13. One end of the first return spring 14 is fixedly connected to one side of the tooth ring 9.

[0025] When the connecting rod 8 drives the toothed ring 9 to move, the toothed ring 9 will disengage from the inside of the limiting toothed groove 11 and enter the inside of the movable groove 12, making it convenient to rotate the connecting rod 8 to adjust the angle of the high-definition camera 7. After the angle of the high-definition camera 7 is adjusted, the connecting groove 13 will reset and retract, and the connecting groove 13 will drive the toothed ring 9 to move and insert into the inside of the limiting toothed groove 11. By setting the limiting toothed groove 11, the limiting toothed groove 11 will limit and fix the connecting rod 8 through the toothed ring 9.

[0026] Furthermore, the handle 5 is internally connected to an extension block 10, the extension block 10 is internally machined with a groove 15, and the groove 15 is internally connected to a pressure block 16. The handle 5 is externally machined with multiple limiting holes 18, and the pressure block 16 is plugged into the limiting holes 18. When it is necessary to increase the length of the handle 5 to facilitate the acquisition of information by the light metering probe 2 and the high-definition camera 7, the pressure block 16 is pressed to disengage from the limiting holes 18, thereby releasing the limitation of the extension block 10, making it easier to pull the extension block 10 outward to increase the length of the handle 5, thus making it easier to hold and operate.

[0027] Furthermore, a second return spring 17 is provided inside the groove 15. One end of the second return spring 17 is fixedly connected to the inner wall of one end of the groove 15, and the other end of the second return spring 17 is fixedly connected to the bottom of the pressure block 16. With the second return spring 17 provided, when the pressure block 16 is pressed, the pressure block 16 will drive the second return spring 17 to compress. When the pressure block 16 is released, the second return spring 17 will return to its original position and extend. The second return spring 17 will drive the pressure block 16 to move, thereby allowing the pressure block 16 to be inserted into the interior of the limiting hole 18 and fixed.

[0028] Working principle: The light from the lamp shines on the silicon photodiode through the photometer probe 2, which excites the photocurrent. After the current is amplified, filtered, and converted from analog to digital, it is converted into an illuminance value by the microprocessor and finally displayed on the display screen 4 to determine whether the light is aging. By pulling the connecting rod 8 outward, the connecting rod 8 will drive the toothed ring 9 to move out of the limiting tooth groove 11. Then, by rotating the connecting rod 8, the high-definition camera 7 will rotate at a certain angle and be aligned with the lamp. By adjusting the focus of the high-definition camera 7 by pressing the button, the external condition of the lamp can be clearly displayed on the display screen 4, thereby determining whether there is any breakage or aging.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
