The utility model discloses a tunnel portal shading shed capable of generating electricity, which relates to the technical field of tunnel construction facilities and comprises a plurality of longitudinal straight ribs and a plurality of transverse arc ribs which are mutually connected, a plurality of mounting holes are defined by the longitudinal straight ribs and the transverse arc ribs, and a first solar panel is arranged in the mounting hole longitudinally located in the middle. First light diffusion plates are arranged in the mounting holes located in the two sides of the solar panel in the longitudinal direction, a light shielding plate or a second solar panel is arranged in the mounting hole close to the first light diffusion plates in the longitudinal direction, and a second light diffusion plate is arranged in the mounting hole close to the light shielding plate or the second solar panel in the longitudinal direction. Supporting columns connected with the ground are arranged at the ends of the transverse arc ribs. The tunnel portal shading shed capable of generating electricity has the beneficial effects of energy conservation, environmental protection and uniform brightness of light in the shed.

This application relates to the field of vehicle technology and discloses a sunshade device and a vehicle. The sunshade device provided by this application includes: a sunshade curtain, which includes a curtain body and a connecting component. One end of the curtain body is connected to the connecting component, and the connecting component is used to connect to the vehicle; a drive mechanism, which is used to drive the curtain body to move so that the curtain body switches between an unfolded state and a retracted state; and a locking mechanism, which includes a first limiting member and a second limiting member. The first limiting member is disposed at the end of the curtain body away from the connecting component, and the second limiting member is disposed on the connecting component. Thus, when the vehicle is parked outdoors, the curtain body can switch to an unfolded state and block the windshield to prevent sunlight from directly entering the vehicle through the windshield. When the vehicle is in motion, the curtain body can switch to a retracted state and be locked by the locking mechanism to prevent the curtain body from shaking.

The utility model discloses an electric forklift overhead guard for a refrigeration house, and particularly relates to the technical field of forklift overhead guards, which comprises an overhead guard main body, a left lamp bracket, a right lamp bracket, a protective net assembly and a water baffle, the overhead guard body comprises a left front leg, a right front leg, a left rear leg, a right rear leg and a top frame, the water baffle is fixedly installed on the inner side of the top frame, the left lamp holder and the right lamp holder are fixedly installed on the inner side of the left front leg and the inner side of the right front leg respectively, and the front supporting leg is fixedly connected with the right supporting leg through the protective net assembly. The protective net welding piece is installed at the front end of the overhead guard main body, so that goods are prevented from falling off and hurting a driver during stacking operation, and the safety is improved; the left lamp holder structure and the right lamp holder structure are redesigned, a front lamp of the forklift is installed on the inner side of the overhead guard body, the width of the whole forklift is narrowed, and trafficability is improved. The front end is protected by the protective net welding piece, so that the front lamp is prevented from being collided and damaged; therefore, the forklift is convenient to operate and suitable for small-tonnage forklifts.

This utility model relates to the field of welding helmet technology, specifically an adjustable head-mounted welding helmet, comprising a welding helmet body, with rotating rods rotatably connected to both sides of the welding helmet body. This utility model involves holding a rectangular block, which in turn moves a circular block via a vertical block. The circular block moves a circular rod, stretching a spring. The circular rod then moves a pointed block, separating it from an arc-shaped rubber strip. Rotating the rectangular block to the left causes the vertical rod to rotate the protective cover via the rotating rods. The protective cover then rotates the goggles upwards. When the goggles are rotated to the appropriate position, the tension on the rectangular block is released, and the spring force causes the circular block to move backwards. The circular block, through the circular rod, moves the pointed block into close contact with the arc-shaped rubber strip. This gives the head-mounted welding helmet an adjustable function, facilitating adjustment of the protective cover's rotation angle without obstructing vision. It also facilitates breathing, drinking, and other operations, improving work efficiency and providing convenience for the user.

This utility model belongs to the field of environmental detection technology, specifically relating to a drone for environmental detection. It includes a drone body with a camera assembly and a support mechanism located on its lower side. The support mechanism includes a rotating rod rotatably connected to the lower side of the drone body and driven by a micro-motor. A support component is also included, positioned below the drone body, with a support foot at its bottom. This support component can be rotated to a horizontal position via the rotating rod, extending beyond the flight wing. During flight in forests, it can prevent damage to the flight wing from collisions with branches and leaves, reducing the risk of drone crashes. This design does not obstruct the camera assembly's field of view, balancing protective functions with normal environmental detection operations, thus improving the drone's applicability in complex forest environments.

The utility model relates to a quick forging hydraulic press with a swing arm blank making function, which adopts a two-column structure and is simultaneously provided with a movable walking board, a centering mechanism and a transverse anvil moving mechanism, so that the quick forging function can be realized, and the centering and punching blank making can be completed, the centering mechanism is arranged on two supporting columns, and the transverse anvil moving mechanism is arranged on the supporting columns. Meanwhile, the included angle between the width direction of the movable walking board and the center connecting line of the two supporting columns ranges from 35 degrees to 40 degrees, the transverse anvil moving mechanism and the movable walking board are arranged in a 90-degree crossed mode, in this way, the view field is not affected, and the supporting columns can be centered in the direction of the center connecting line of the two supporting columns; and interference among the movable walking board, the centering mechanism and the transverse anvil moving mechanism is avoided, and the working efficiency is improved.
