Description

Technical Field

[0001] This utility model relates to the field of safety helmet technology, specifically a solar-powered safety helmet for engineering supervision. Background Technology

[0002] Safety helmets are standard protective equipment for construction supervisors, used in large quantities and worn frequently and for extended periods. However, their application has two main drawbacks:

[0003] 1. The intense sunlight in hot weather makes the wearer feel less comfortable, resulting in a lower willingness to wear the garment and a higher likelihood of violations such as not wanting to wear it or not wearing it at all.

[0004] 2. The top of the head area has poor ventilation, making it easy to feel stuffy and sweaty. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a solar-powered safety helmet for engineering supervision that is simple in structure, easy to install, improves wearing comfort, and prevents heatstroke and dizziness.

[0006] This utility model is achieved through the following technical solution: a solar-powered safety helmet for engineering supervision, comprising a main helmet body, a solar panel, a charge / discharge controller, an energy storage battery, and a turbine DC fan. The solar panel is disposed on the brim of the main helmet body. The charge / discharge controller and the turbine DC fan are respectively disposed at the rear end of the main helmet body. The charge / discharge controller is electrically connected to the solar panel, the energy storage battery, and the turbine DC fan. The air outlet of the turbine DC fan housing is connected to an air duct box. Air duct hoses are connected to both sides of the air duct box, and the air duct hoses extend from back to front along the bottom edge of the main helmet body. The air outlet of the air duct hoses is bent into the inner cavity of the main helmet body.

[0007] Furthermore, the air duct hose is fixed to the bottom end of the main cap body by clamps.

[0008] Furthermore: the caliper includes a ring-shaped locking ring, the locking ring having a U-shaped fastening part, the locking ring being fitted onto the air duct hose, and the fastening part being fastened to the cap edge at the bottom end of the main cap body.

[0009] Furthermore, anti-slip teeth are provided on both sides of the inner wall of the snap-fit ​​part.

[0010] Furthermore, the solar panel is fixed to the brim of the main hat body by adhesive bonding.

[0011] Furthermore: a mounting plate is provided at the rear end of the main cap body, the turbine DC fan is fixed to the mounting plate by bolts, and the energy storage battery and the charge / discharge controller are respectively located on the side of the turbine DC fan.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. By attaching solar panels to the brim of the main helmet body, and placing the charge / discharge controller, turbine DC fan, and energy storage battery at the rear of the main helmet body, a duct box is connected to the air outlet of the turbine DC fan housing. Air duct hoses are installed on both sides of the duct box, with the outlet ends of the hoses bent into the inner cavity of the main helmet body. This allows for installation on a conventional safety helmet base, without compromising the original protective effect of the helmet. The solar panels convert sunlight into electrical energy to drive the turbine DC fan, generating airflow that is then directed through the duct hoses into the inner cavity of the main helmet body. This cools the top of the head, preventing heatstroke and dizziness, improving wearing comfort, enhancing the mental state of supervisors, and promoting higher concentration and work efficiency. The structure is simple and ingenious.

[0014] 2. By attaching the solar panels to the brim of the main hat body, the brim area, compared to the top of the hat, can ensure sunlight exposure while being less susceptible to damage from external factors such as bumps and scratches, thus improving the safety of solar panel installation.

[0015] 3. This utility model utilizes the existing structural space of the safety helmet to rationally arrange components such as solar panels, charge and discharge controllers, turbine DC fans, and air duct hoses, eliminating the need to purchase and replace safety helmets separately, reducing usage costs, and is easy to install and lightweight.

Detailed Implementation

[0022] Figures 1 to 5 This utility model provides a schematic diagram of the structure of a solar-powered safety helmet for engineering supervision, including a main helmet body 1, a solar panel 2, a charge / discharge controller 3, an energy storage battery 4, and a turbine DC fan 5. The solar panel 2 is mounted on the brim 6 of the main helmet body 1. The charge / discharge controller 3 and the turbine DC fan 5 are respectively mounted at the rear end of the main helmet body 1. The charge / discharge controller 3 is electrically connected to the solar panel 2, the energy storage battery 4, and the turbine DC fan 5. The air outlet of the shell 7 of the turbine DC fan 5 is connected to an air duct box 8. Air duct hoses 9 are connected to both sides of the air duct box 8, and the air duct hoses 9 extend from back to front along the bottom edge of the main helmet body 1. The air outlet 10 of the air duct hose 9 is bent into the inner cavity of the main helmet body 1.

[0023] In this embodiment, the turbine DC fan 5 is a 5015 type turbine DC fan with a wide input voltage range.

[0024] The air duct hose 9 is fixed to the bottom end of the main cap body 1 by clamps 11.

[0025] The clamp 11 includes a ring-shaped locking ring 12, and a U-shaped fastening part 13 is provided on the locking ring 12. The locking ring 12 is fitted onto the air duct hose 9, and the fastening part 13 is fastened to the cap edge 14 at the bottom of the main cap body 1.

[0026] The flexible duct hose 9 is fitted with a snap ring 12 and snapped onto the cap edge 14 with a fastening part 13. The structure is simple and easy to install.

[0027] Anti-slip teeth 15 are provided on both sides of the inner wall of the snap-fit ​​part.

[0028] The anti-slip teeth 15 can improve the stability of the connection between the snap-fit ​​part and the cap edge 14, prevent the snap-fit ​​part 13 from falling off, and thus improve the stability of the connection between the air duct hose 9 and the main cap body 1.

[0029] The solar panel 2 is fixed to the brim 6 of the main hat body 1 by adhesive bonding.

[0030] The rear end of the main cap body 1 is provided with a mounting plate 16, and the turbine DC fan 5 is fixed to the mounting plate 16 by bolts 17. The energy storage battery 4 and the charge and discharge controller 3 are respectively located on the side of the turbine DC fan 5.

[0031] During use, the solar panel 2 generates electricity when exposed to sunlight during the day. The generated electricity is stored in the energy storage battery 4 and used to power the turbine DC fan 5. The charge and discharge controller 3 controls the charging and discharging of the energy storage battery 4 to protect the energy storage battery 4 or the turbine DC fan 5 from overcharging or over-discharging, thus achieving load control and circuit protection functions. The airflow generated by the turbine DC fan 5 enters the air duct hose 9 through the air duct box 8 and then blows out from the air outlet 10 of the air duct hose 9 into the inner cavity of the main cap body 1, thereby cooling the top of the head and achieving the effect of preventing heatstroke and dizziness.

[0032] The above detailed description is a specific description of a feasible embodiment of the present utility model. This embodiment is not intended to limit the patent scope of the present utility model. All equivalent implementations or modifications that do not depart from the present utility model should be included in the patent scope of this case.
