The device comprises a first plate, a second plate, a supporting structure and an anti-collision structure, the second plate and the first plate are oppositely arranged, the first plate and the second plate are suitable for forming a containing cavity, the supporting structure is located in the containing cavity, one end of the supporting structure abuts against the first plate, and the other end of the supporting structure abuts against the second plate. The other end of the supporting structure abuts against the second plate, and the anti-collision structure is arranged in the width direction of the first plate and / or the second plate.

The utility model discloses an anti-deformation plastic bucket, and relates to the technical field of anti-deformation plastic buckets, the anti-deformation plastic bucket comprises an anti-deformation bucket and a sealing end cover, the sealing end cover is installed at the top of the anti-deformation bucket, the anti-deformation bucket comprises a plastic bucket body, a connecting screw is installed at the top of the plastic bucket body, and supporting blocks are installed at the four corners of the bottom of the plastic bucket body correspondingly; according to the scheme, through the design that the annular through groove and the arc-shaped top plate are arranged in the buffering ring, the double-layer buffering effect can be provided for the outer portion of the anti-deformation barrel which is inclined or collapsed accidentally, and through the mechanism that the buffering ring and the arc-shaped top plate act jointly, the anti-deformation barrel is not prone to falling off. Compared with the prior art, the plastic barrel body is prevented from collapsing and being damaged by knocking, the plastic barrel body bears downward pressure, the pressure brought to the plastic barrel body is reduced, in addition, due to the design, the energy conduction path of the plastic barrel body is prolonged when the plastic barrel body is impacted, the impact force is further dispersed, and deformation and damage caused by external force or collapse are effectively prevented.

The invention relates to the technical field of wind power generation devices, and discloses a speed reduction buffer mechanism of a wind power generation device capable of tracking the wind direction, which comprises a base, the top of the base is fixedly connected with a barrel frame, the top of the barrel frame is fixedly connected with a protective frame, and the inner wall of the protective frame is fixedly connected with a generator. And a rotating rod is fixedly connected to the output end of the generator, fan blades are fixedly connected to the surface of the rotating rod, a brake component is arranged in the protection frame, and an extrusion component is arranged in the protection frame. When the generator needs to be subjected to deceleration protection, the brake pads are pushed by the extrusion parts to move towards the surface of the brake ring, the brake pads extrude the arc frame to deform during movement, the arc frame pulls the two brake pads to move close to each other during contraction, and meanwhile, the round rods are extruded to move towards the interior of the positioning block; and the stability of the brake pad for extruding the friction ring is improved through the round rod.

This utility model discloses a hydraulic oil tank for a hydraulic oil pump. The tank body has cross-sections formed at a set of diagonal sides, one of which has an oil suction port and the other has an oil return port. The oil suction port's pipe extends into the tank body and connects to a coarse filter. The coarse filter is connected to a funnel-shaped expansion suction head via a threaded connector. The oil return port's outlet is connected to a fine filter, which is connected to a one-way throttle valve. The one-way throttle valve is connected to a flow-regulating pipe, which is curved and located within the tank body. This invention adds a funnel-shaped expansion suction head at the oil suction port to reduce suction resistance and minimize inlet disturbance. The addition of a flow-regulating pipe at the oil return port slows down the return oil flow. Combined with the 45° oblique cut, this effectively disperses the impact force of the oil and reduces disturbance. Furthermore, the diagonal distribution of the oil suction and return ports extends the oil flow path, promoting impurity sedimentation and air separation.
