Description

Technical Field

[0001] This utility model belongs to the field of lighting technology, specifically relating to a lighting device for internal inspection of power plant boilers. Background Technology

[0002] Existing lighting lamps have low brightness and diffused, unfocused light, affecting workers' inspection work in dim environments. The "Industrial Boiler Internal Inspection Lighting Device" disclosed in application number "CN201821925705.4" is a lamp that can be worn alone on the head or fixed to a safety helmet. The second and third lamp heads on the headband have clips for flexible positioning, and an alarm on the power box indicates low battery. However, this device has the following drawbacks: in actual use, the installation method is not secure enough; the illumination range cannot be adjusted during lighting; and during boiler internal inspection, due to the relatively enclosed environment and poor sound transmission, workers cannot promptly notify external personnel of any discovered hazards. Utility Model Content

[0003] The purpose of this utility model is to provide a lighting device for internal inspection of power plant boilers, so as to solve the above-mentioned technical problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution: It includes a headband with a cheek strap connected to its bottom and elastic straps connected to both ends. Two soft rubber ear hooks are connected to the bottom of the headband, and a Bluetooth in-ear headphone is mounted on the lower part of each ear hook. A chin pad is connected to the middle of the cheek strap, and the cheek strap has a cavity extending along its length. A flexible communication cable is installed inside the cavity. A wireless Bluetooth microphone is mounted on the chin pad, and the wireless Bluetooth microphone is connected to the Bluetooth in-ear headphone via the flexible communication cable. A headlamp stand is connected to the front of the headband, and a gear joint is provided on the headlamp stand. A rubber lamp holder is located inside the gear joint, and a main lamp is connected to the rubber lamp holder. The main lamp has a low beam ring and a high beam ring. A switch is located on the top of the headlamp stand, controlling the activation of the low beam ring and the high beam ring.

[0005] Furthermore, a head strap is provided in the middle of the cheek strap.

[0006] Furthermore, a rechargeable battery is embedded on one side of the headlamp holder, and a hidden waterproof charging hole is provided on the side wall of the headlamp holder near the rechargeable battery.

[0007] The inner side of the limiting headband is equipped with an anti-slip pad.

[0008] The section of the cheek strap without a flexible communication cable has an adjustable length allowance.

[0009] Preferably, the low beam ring is located in the middle area of ​​the main lamp tube's light-emitting area, and the high beam ring is distributed in the outer area of ​​the main lamp tube's light-emitting area.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1) The device's stability on the head is enhanced through the coordinated use of a chin pad, elastic straps, soft ear hooks, and a back head strap, preventing it from falling off due to excessive head movement. The wireless Bluetooth microphone and in-ear headset facilitate communication between staff and external personnel.

[0012] 2) The high beam and low beam can be switched to easily illuminate the situation at a distance and near inside the boiler, improving visibility. Attached Figure Description

[0017] A lighting device for internal inspection of a power plant boiler includes a headband 1, with two soft rubber ear hooks 2 connected to the bottom of the headband 1, a cheek strap 3 connected to the bottom of the headband 1, a chin pad 4 connected to the middle of the cheek strap 3, and a back head strap 9 in the middle of the cheek strap 3. A headlamp holder 5 is fixed to the front of the headband 1, the headlamp holder 5 has a gear joint 6, a rubber lamp holder 7 is provided inside the gear joint 6, and a main lamp tube 8 is provided on the side of the rubber lamp holder 7. The main lamp tube 8 has a low beam ring 81 in the middle area of ​​the light-emitting area and a high beam ring 82 distributed in the outer area.

[0018] The headband 1 is made of flexible PVE material. During the wearing process, the headband 1 fits the skull of the staff member and the device is placed above the staff member's eyebrows. At this time, the soft rubber ear hook 2 is hung on the auricle for positioning. The cheek strap 3 fits the staff member's cheek, and the chin pad 4 wraps around the staff member's chin. The back head strap 9 is tied to the back of the staff member's head to improve the stability of the headband 1 after installation.

[0019] A rechargeable battery 10 is embedded on one side of the headlamp holder 5, and a hidden waterproof charging port 11 is opened on the top side of one side of the headlamp holder 5. A switch 51 is located on one side of the top of the headlamp holder 5. See reference. Figure 2 The lighting status of the high beam ring 82 and the low beam ring 81 can be switched by pressing the switch 51, which is convenient for illuminating the situation at a distance and near inside the boiler.

[0020] The headband 1 has elastic straps 12 at both ends and an anti-slip pad 13 on the inside. By contracting the elastic straps 12, the headband 1 is fixed to the worker's head. At this time, the anti-slip pad 13 fits against the worker's hair or forehead to prevent the headband 1 from falling off.

[0021] A cavity extends along the length of the cheek strap 3, containing a flexible communication cable 14. A wireless Bluetooth microphone 15 is located at the front of the jaw pad 4. A Bluetooth in-ear headset 16 is mounted on one side of the top of the soft rubber ear hook 2. The wireless Bluetooth microphone 15 and the Bluetooth in-ear headset 16 are connected via the flexible communication cable 14. During use, personnel inside the boiler can communicate with personnel outside the boiler via the wireless Bluetooth microphone 15 and the Bluetooth in-ear headset 16, facilitating communication with external staff and providing real-time updates on boiler malfunctions.

[0022] To accommodate people with different head circumferences, the section of the cheek strap 3 without the flexible communication cable 14 has an adjustable length allowance, allowing adjustment of the usable length of the cheek strap 3.

[0023] The invention is used as follows: It is worn on the head, with the headband 1 fitting snugly against the skull, the elastic strap 12 at the back of the head, the soft ear hooks 2 hanging on the ears, and the cheek straps 3 fitting snugly against the cheeks. The chin pad 4 is then wrapped around the jawline. Through these front-to-back and up-and-down positioning mechanisms, the device is stabilized on the worker's head. Pressing the switch 51 selects between high beam and low beam illumination. During use, if communication with someone outside the boiler is required, the voice of the person inside the boiler is transmitted via the wireless Bluetooth microphone 15, and the voice commands from the person outside the boiler are received via the Bluetooth in-ear headphones 16.
