Description

Technical Field

[0001] This utility model relates to the field of wind power generator maintenance technology, and in particular to a new type of headlamp specifically designed for wind power generator maintenance. Background Technology

[0002] In the field of wind turbine maintenance, the hub, as one of the core components, usually has a small and enclosed internal space with extremely poor natural lighting conditions, which seriously affects the maintenance personnel's observation and operation of the equipment components. In order to ensure the smooth progress of maintenance work, maintenance personnel generally use headlamps to obtain lighting.

[0003] However, in actual operation, due to the limited internal space of the wheel hub, the range of head movement and the beam angle of the headlamp for maintenance personnel are easily obstructed by surrounding structural components. This leads to frequent illumination blockage of the headlamp beam, preventing the area to be inspected from receiving sufficient and effective lighting, thus affecting the efficiency and accuracy of the maintenance work. Furthermore, maintenance work often requires checking and operating components in different locations, placing a high demand on the headlamp's mobility. However, because the headlamp is worn on the head, its illumination position is limited by head posture, making it difficult to flexibly adapt to the lighting needs of different maintenance points. In this situation, maintenance personnel usually need to carry additional lighting equipment to supplement illumination. This not only increases the amount of equipment carried and the workload, but also, when holding lighting equipment in a confined space, it occupies the maintenance personnel's hand operating space, preventing them from freeing their hands and further affecting the convenience and safety of the maintenance operation.

Detailed Implementation

[0017] To better understand the purpose, structure, and function of this utility model, the embodiments and features described herein can be combined with each other without conflict. The utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0018] Example 1 like Figures 1-8 As shown in the figure, this embodiment illustrates a novel headlamp specifically designed for wind turbine maintenance, comprising a connecting base 10, an elastic strap 20, and a lamp head body 70. The two connecting ends of the connecting base 10 are fixedly connected to the two ends of the head strap 20, respectively. The elastic strap 20 wraps around the human head, utilizing its elastic restoring force to create a snug fit, distributing the weight of the lamp body to the head and ensuring the stability and comfort of wearing the headlamp. The lamp head body 70 includes an LED light source module, a focusing lens, and a heat dissipation housing. The LED light source module is used for the core lighting unit to provide high-brightness light. The focusing lens is composed of a composite lens array, including refractive and reflective lenses. It achieves directional focusing of light through curved surface geometry design and is used to control the focusing or scattering range of light. The heat dissipation housing is made of thermally conductive plastic to prevent overheating.

[0019] In this embodiment, as shown Figure 1 As shown, it also includes a lamp body plug-in female socket 30 located in the middle of the connector 10. The lamp body plug-in female socket 30 is a rigid interface base, which is fixed in the middle area of ​​the connector 10 by integral molding or thread fastening. The lamp body plug-in female socket 30 has a plug-in cavity with guiding and locking functions on the side facing the lamp head body 70, and is coupled with a lamp body plug-in male socket 40 in a pluggable manner to form a mechanical locking pluggable fit. The male connector 40 of the lamp body includes a connector and a magnet 46. The shape of the connector is adapted to the connector cavity of the female connector 30 to achieve a non-loosening pluggable connection. Magnet 46 is embedded inside the connector. Magnet 46 is a high-energy-product neodymium iron boron magnet. When the male connector 40 of the lamp body is separated from the female connector 30, it can be directly attracted and fixed to iron-containing metal surfaces such as the inner wall of the hub, forming a hand-free directional lighting fulcrum and realizing seamless switching between head-mounted and fixed-point lighting modes.

[0020] During implementation, after the lamp body male connector 40 is separated from the lamp body female connector 30, the lamp body male connector 40 can be directly attached to the iron-containing metal surface such as the wheel hub under the magnetic attraction, without the need to carry special fixing tools, which significantly reduces the amount of equipment to carry and the workload, and completely frees the hands of maintenance personnel.

[0021] In this embodiment, as shown Figure 2 As shown, the lamp body plug-in female socket 30 includes a base plate 31, an anti-detachment horizontal plate 32, a wedge-shaped vertical plate 33, a limiting wing plate 34, and a positioning protrusion 35; The base plate 31 is fixed on one side of the connecting seat 10. The anti-detachment cross plate 32 is integrally formed on one side of the far edge of the base plate 31 and forms an L-shaped limiting member with the base plate 31. It is used to apply axial limiting to the lamp body plug male 40 after it is fully inserted, that is, to limit the excessive insertion of the lamp body plug male 40, and to serve as the mounting carrier for the positioning protrusion 35.

[0022] The wedge-shaped vertical plate 33 is a guide and positioning component. It adopts four symmetrically distributed wedge structures, with two forming a group. The two groups of wedge-shaped vertical plates 33 are symmetrically arranged on the intersection side of the base plate 31 and the anti-detachment horizontal plate 32 to form a wedge-shaped guide groove. The two groups of wedge-shaped vertical plates 33 are vertically fixed to the common connection surface of the base plate 31 and the anti-detachment horizontal plate 32 by hot melt welding. It forms an initial constraint on the insertion direction of the lamp body plug male 40. It quickly guides the lamp body into the wedge-shaped guide groove through the "sloping surface guide", which solves the problem of "blind insertion" when maintenance personnel operate with one hand, avoids the male 40 from deviating from the insertion trajectory due to vibration or misoperation, and improves the insertion stability. Two limiting wing plates 34 are respectively set on the opposite side of the two sets of wedge-shaped vertical plates 33. The end of the wing plate extends into the wedge-shaped guide groove to form an elastic protrusion. After the lamp body plug male 40 is fully inserted, the elastic deformation of the elastic protrusion on the limiting wing plate 34 forms a radial lock with the lamp body plug male 40, ensuring that the lamp body has no risk of loosening when the head swings, bends, etc. in the head-wearing mode, and adapts to the dynamic mechanical environment of maintenance work.

[0023] The positioning protrusion 35 is vertically fixed to the inner side of the anti-detachment horizontal plate 32 by injection molding. The inner side is the side facing the wedge-shaped space, which is used to further strengthen the stability and prevent the lamp body plug male 40 from shifting during dynamic operation.

[0024] Specifically, in head-mounted mode, the connector 10 transmits the binding force of the elastic strap 20 to fix the lamp head body 70 in position; During disassembly, the lamp body male connector 40 is separated from the lamp body female connector 30 by applying axial pulling force with one hand, that is, the limiting wing plate 34 is elastically unlocked. At this time, the connector of the lamp body male connector 40, the lamp body rear cover 50, the multi-degree-of-freedom hinge 60, and the lamp head body 70 constitute an independent lighting unit. The high-energy-product neodymium iron boron magnet 46 embedded in the male head 40 generates a magnetic attraction force, allowing the independent lighting unit to be directly attached to iron-containing metal surfaces such as the inner wall of the wheel hub, forming a hand-free fixed lighting fulcrum. The lamp head body 70, through the damping suspension function of the multi-degree-of-freedom hinge 60, can still finely adjust the lighting angle after being magnetically fixed, and can illuminate maintenance areas that cannot be covered by space obstruction when wearing the headlamp, such as deep gaps in the wheel hub and side bolts, while freeing up the space for hands operation.

[0025] In this embodiment, a lamp body rear cover 50 is also provided on one side of the lamp body plug male connector 40. The lamp body rear cover 50 is a hollow structure base. The middle part of one side is rigidly connected to the plug of the lamp head body 70 plug male connector 40 by integral molding or thread fastening. The lamp body rear cover 50 is recessed on the side facing the lamp head body 70 to form an accommodating space. When the lamp head body 70 rotates around the multi-degree-of-freedom hinge 60 to be parallel to the plane of the lamp body rear cover 50, the lamp head body 70 is embedded in the accommodating space to achieve compact storage. On the other side of the lamp body rear cover 50, there is a multi-degree-of-freedom hinge 60. The multi-degree-of-freedom hinge 60 is a three-dimensional angle adjustment mechanism. One end of it is rotatably connected to the side of the lamp body rear cover 50 away from the lamp body plug male head 40 through a rotating shaft hinge. The other end is hinged to one side of the lamp head body 70 through a damped rotating pair, so as to realize the adjustable connection of the lamp head body 70 in three degrees of freedom: yaw, pitch and rotation.

[0026] It should be noted that each rotating joint of the hinge 60 has a built-in silicone rubber damping bushing, which balances the gravitational torque of the lamp head body 70 through frictional damping force, so that the adjusted angle position can be stably suspended.

[0027] During implementation, the three-dimensional adjustable connection allows the lamp head body 70 to flexibly adjust the illumination direction according to the head movements of the maintenance personnel in head-mounted mode. In magnetic mode, the angle can be finely adjusted by fixing the position of the adsorption location. For example, when adsorbed on the side wall of the wheel hub, it can rotate 180° laterally to illuminate the opposite component. The controllable friction provided by the silicone rubber damping bushing ensures that the lamp head body 70 does not "fall due to gravity" or "vibration shift" at any adjusted angle, solving the pain point of "needing to hold and fix it after adjusting the angle" in a confined space.

[0028] In this embodiment, as shown Figure 3 As shown, the connector includes a bearing plate 41, a positioning rib 42, a wedge-shaped guide post 43, a positioning guide post 44, and a locking pin 45; The support plate 41 is located in the middle of the lamp body rear cover 50. The mounting surface of the support plate 41 is aligned with the insertion hole of the lamp body plug-in female socket 30 to form a plug-in quick-connect structure. Positioning ribs 42 are located on one side edge of the bearing plate 41. Four wedge-shaped guide posts 43 are symmetrically arranged along the left-right direction of the bearing plate 41. The ends of the two opposite wedge-shaped guide posts 43 on the outer sides are provided with positioning guide posts 44, and the ends of the two opposite wedge-shaped guide posts 43 on the inner sides are provided with locking inserts 45. Figure 4 As shown, each wedge-shaped guide post 43 has a guide slope on its outer side wall, which complements the inner slope of the wedge-shaped vertical plate 33 of the lamp body plug-in socket 30, so as to achieve self-guiding correction during the plugging process and ensure the smoothness of the plugging and unplugging action. The positioning guide post 44 has a positioning groove at its end that fits with the positioning protrusion 35 on the lamp body plug-in female seat 30, forming an axial anti-disengagement constraint. In this embodiment, as shown Figure 5 , 6 As shown, the multi-degree-of-freedom hinge 60 includes a hinge base 61, a horizontal hinge shaft 62, a transmission swing arm 63, a two-way hinge shaft 64, and a Z-axis hinge 65. The hinge base 61 is fixed within the accommodating space of the lamp body rear cover 50. The horizontal hinge shaft 62 is fixed to one side of the hinge base 61. An adjustment groove is provided on one side of the lamp head body 70. The Z-axis hinge 65 is located on the inner wall of the adjustment groove. The Z-axis hinge 65 is hinged to the bidirectional hinge shaft 64. The lamp head body 70 swings vertically through the Z-axis hinge 65, which can flexibly adjust the up and down illumination position of the lamp head body 70. A silicone rubber damping bushing is provided between the Z-axis hinge 65 and the bidirectional hinge shaft 64. The friction balances the weight torque of the lamp head body, allowing the lamp head body 70 to be stably suspended at any vertical swing angle, avoiding "lighting deviation caused by gravity falling". This is suitable for the operation requirements of one-handed angle adjustment and fixed operation when the hand is released in a narrow space.

[0029] Furthermore, the lateral hinge shaft 62 and the bidirectional hinge shaft 64 are hinged through the transmission swing arm 63. The two ends of the transmission swing arm 63 are provided with silicone rubber damping bushings, so that the lamp head body 70 can be stably suspended at any lateral angle, realizing three-dimensional spatial angle adjustment.

[0030] A switch 80 is provided on one side of the lamp head body 70. The switch 80 is embedded in silicone material and is integrated into the side wall of the lamp head body 70 away from the lighting direction by means of buckle and hot melt fixing. Its installation position is adapted to one-hand blind operation and corresponds to the natural landing point of the thumb when the maintenance personnel hold the lamp head. The button has a conductive spring assembly inside, which is electrically connected to the LED light source module drive circuit inside the lamp head body 70 through a wire, forming a control link of "button-circuit-light source".

[0031] In this embodiment, as shown Figure 7 As shown, a soft pad 90 is provided on the side of the connector 10 away from the lamp head body 70. The soft pad 90 is made of memory foam and has an overall arc-shaped fitting structure. The arc matches the contour of the back of the human head. It is fixed to the side of the connector 10 away from the lamp head body 70 by adhesive backing, that is, the contact surface with the head. Its edges are wrapped with silicone, which not only enhances the fit and sealing with the connector 10, but also prevents the edges of the memory foam from getting fuzzy due to friction, making it suitable for long-term use.
