This utility model discloses a nitrogen generator that is easy to maintain, specifically relating to the technical field of nitrogen generators. It includes a base, with a clamping component on the top of the base for fixing the nitrogen generator, and an adjusting component on the outside of the clamping component for adjusting the maintenance angle of the nitrogen generator. The adjusting component includes an adjusting frame on the top of the base, with toothed plates mounted on the front sides of both ends of the adjusting frame. A movable column is located at the bottom of the toothed plate, and a gear meshing with the toothed plate is sleeved on the outside of the movable column. This utility model uses a first electric push rod to move the adjusting frame and toothed plates backward. The toothed plates, through the gears, drive a second telescopic rod and clamping plate on the movable column to rotate, thereby adjusting the maintenance angle of the nitrogen generator. This improves the maintenance field of vision, reduces blind spots, and facilitates maintenance, eliminating the need for prolonged bending and stooping, effectively reducing the physical burden on workers when maintaining the nitrogen generator.

One end of the first protective net is fixedly connected to the cab through a plurality of first fixing plates, the other end of the first protective net is fixedly connected to the cab through a plurality of second fixing plates, the second protective net is fixed to the lower portion of one side of the cab, a plurality of first grids are evenly and vertically distributed on the first protective net, a plurality of second grids are evenly and vertically distributed on the second protective net, and the first grids are radially inclined by a preset angle along the center line in the width direction of the first protective net; the device can effectively resist impact of splashes in the excavation operation process, the integrity of a driving space and the personal safety of a driver are guaranteed, the first grids are obliquely arranged in the radial shape, and compared with traditional grids arranged in parallel, the first grids can effectively reduce blocking of the sight of the driver, the view field of the driver is expanded, and the safety of the driver is improved. And the visual blind area is reduced.

The utility model discloses a manhole access door convenient to observe and clean, which belongs to the technical field of material containers, and comprises a manhole door and a cover plate rotatably arranged on one side of the manhole door, a mounting hole is formed in the middle of the cover plate, an observation window is welded in the mounting hole, and the observation window is connected with the manhole door. The cover plate is provided with a nozzle kit, one end of the nozzle kit is provided with a compressed air blowing system, the nozzle kit comprises two compressed air blowing nozzles, the nozzle ends of the compressed air blowing nozzles penetrate to the inner side of the cover plate, the cover plate on the manhole door can be combined with the observation window, and the cover plate can be conveniently cleaned. The compressed air blowing system is matched with the nozzle suite for use, and compressed air or inert gas is used for blowing the explosion-proof glass on the inner side of the container through the compressed air blowing nozzle, so that the purpose of cleaning is achieved, the requirement for visual observation of a continuous operation device is met, and the production progress and quality are improved.

A kind of cloth platform of layout machine, including frame and platform assembly arranged on frame, platform assembly is arranged in the inclination of front low and rear high, forms the inclined work plane for fixing cloth, four corners are respectively provided with independent height adjusting mechanism, each height adjusting mechanism can be individually adjusted height, realize the dynamic adjustment of height difference of four corners of platform assembly.The structure design can reduce the bending amplitude of operator when handling cloth, reduce the risk of waist fatigue and disease;Inclined plane can also improve the observation field of view of operator to the overall condition of cloth, reduce visual blind area, facilitate timely discovery of defects such as damage, stain, reduce the rate of defective product of subsequent processing;Independent adjustable height adjusting mechanism can adapt to different operator height, cloth thickness and layout process requirement, improve work efficiency and applicability.

The utility model discloses a four-eye vision positioning device, which comprises a protective shell and four camera modules, two sides of the protective shell are respectively provided with two mounting grooves, the camera modules are arranged in the corresponding mounting grooves, the outer side of the protective shell is provided with four U-shaped side frames, and each U-shaped side frame is provided with a U-shaped groove. The side walls of the four camera modules are all provided with spherical connecting mechanisms, the outer sides of the spherical connecting mechanisms are sleeved with supporting rings, and the bottom ends of the supporting rings are fixedly connected with supporting rods. The front binocular camera and the rear binocular camera are formed through the four camera modules, by means of the layout, the device can cover the view fields of the front view angle and the rear view angle at the same time, the observation area is remarkably increased, depth information can be obtained through the stereoscopic vision technology, data of the four camera modules are processed through a fusion algorithm, and the image quality is improved. The device is particularly suitable for visual SLAM (Simultaneous Localization and Mapping) application in a complex environment, and can realize stable positioning in dynamic and static scenes.
