Description

Technical Field

[0001] The invention relates to the technical field of water surface photovoltaic power generation floating body fasteners, in particular to a self-locking water floating body anti-rotation nut. Background Art

[0002] The existing anti-detachment method for fasteners between adjacent floating bodies of surface photovoltaic systems mostly adopts a rotation-stopping anti-detachment method of bolts, nuts and pins. This method is complicated to operate and requires a large amount of work. It also requires different numbers of ear plates to be stacked and the nut rotation angles to be different. Multiple through holes need to be drilled on the bolts, which affects the strength of the bolts. Summary of the invention

[0003] The purpose of the present invention is to provide a nut for a floating body on water, so as to solve the problem that the anti-rotation and anti-slip method using bolts and nuts with pins proposed in the above background technology is complicated to operate and the strength of the bolts is damaged.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a water floating body stop nut, comprising: a body, a flange body, a reinforcement plate, a wedge-shaped head and a wedge-shaped protrusion, the bottom of the body is provided with a flange body, the outer circumferential array of the body is provided with a reinforcement plate, the bottom of the wedge-shaped head is respectively connected to the body and the reinforcement plate, and the side of the wedge head close to the inner side of the body is provided with a wedge-shaped protrusion; the height of the wedge head gradually increases along the counterclockwise direction of the body, and the connecting line between the vertices of the wedge head is a threaded line; the wedge-shaped protrusions are of uniform size, and the connecting line between the wedge-shaped protrusions is a threaded line.

[0005] When the fixing nut of the present invention is connected to a bolt, the end of the body close to the flange body is first inserted into the end of the bolt. During the continuous rotation of the body, the wedge-shaped protrusion is screwed into the thread teeth of the bolt. The wedge-shaped protrusion squeezes the thread teeth to generate friction, which can stably fix the nut and the bolt and prevent the fixing nut from loosening. The connecting line between the wedge-shaped protrusions is a thread line shape, and the thread line shape is consistent with the thread line of the bolt, so that the wedge-shaped protrusion can be rotated along the thread teeth of the bolt.

[0006] Furthermore, an array of anti-skid protrusions is provided at the bottom of the flange body, one end of the anti-skid protrusion is tightly attached to the bottom of the flange body, and the other end is provided with an inclined surface, the inclined surface includes an inclined high surface and an inclined low surface, and the thickness of the anti-skid protrusion gradually decreases from one end of the inclined high surface to one end of the inclined low surface. When the flange body is placed horizontally, the thicker inclined high surface of the anti-skid protrusion contacts the horizontal surface, and when the nut and the bolt are tightened, under the action of external force, after the nut moves to the end of the bolt, the inclined high surface of the anti-skid protrusion is embedded in the object until the inclined low surface contacts the surface of the object, at which time the nut can no longer be tightened and fixed; after the nut is fixed with the bolt, the anti-skid protrusion at the bottom of the nut contacts the surface of the object, which can prevent the nut from loosening.

[0007] Furthermore, the wedge-shaped head includes: a first contact surface, a second contact surface, a height-adjustable surface and a convex point mounting surface, the first contact surface is used to connect with the body, the second contact surface is used to connect with the reinforcing plate, the height-adjustable surface is vertically arranged with the first contact surface, the convex point mounting surface is connected with the height-adjustable surface, and the side wall of the convex point mounting surface is used to fix the wedge-shaped convex point. The height of the wedge-shaped head is different, so the height of the height-adjustable surface is different at different positions, so that the line between the vertices of the wedge-shaped head can form a thread line.

[0008] Furthermore, the wedge-shaped protrusion is in a quadrilateral shape, and each corner of the wedge-shaped protrusion is rounded. The wedge-shaped protrusion cuts into the thread teeth from the bolt section, squeezes to generate friction, and when the body continues to screw into the bolt, the quadrilateral wedge-shaped protrusion is stuck in the round surface, and the protrusion is not easy to jump out, thereby achieving the effect of stopping rotation.

[0009] Furthermore, the main body is a hollow body of revolution.

[0010] Furthermore, the number of the wedge-shaped heads is 2 to 18.

[0011] Furthermore, there are 2 to 18 anti-slip protrusions.

[0012] Furthermore, the height of the reinforcing plate is lower than the height of the main body.

[0013] The wedge-shaped protrusions provided in the present invention are inserted into the arc-shaped thread teeth. After the quadrilateral wedge-shaped protrusions are inserted into the circular surface, the protrusions are not easy to jump out, thereby achieving the effect of stopping rotation, changing the previous anti-rotation and anti-slip method of the bolt drilling pin, and ensuring the connection strength between the nut and the bolt; at the same time, the wedge heads are arranged in an array above the main body in different heights, and the connecting line between the wedge heads is in the shape of a thread line, ensuring that the wedge-shaped protrusions can move along the corresponding bolt thread teeth; after the nut is fixed to the bolt, the anti-slip protrusions at the bottom of the nut contact the surface of the object, preventing the nut and the bolt from loosening after being connected, extending the service life of the bolt, and improving the fixing efficiency of the float.

The bottom of the body 1 is provided with a flange body 2, the outer circumferential array of the body 1 is provided with a reinforcing plate 3, the bottom of the wedge-shaped head 4 is respectively connected with the body 1 and the reinforcing plate 3, and the side of the wedge-shaped head 4 close to the inner side of the body 1 is provided with a wedge-shaped protrusion 5; the height of the reinforcing plate is lower than the height of the body; the height of the wedge-shaped head 4 gradually increases along the counterclockwise direction of the body 1, and the connecting line between the vertices of the wedge-shaped head 4 is a threaded line; the wedge-shaped protrusions 5 are of uniform size, and the connecting line between the wedge-shaped protrusions 5 is a threaded line; the body 1 is a hollow rotating body, which is convenient for the body to be inserted into the bolt.

[0022] When the fixing nut of the present invention is connected to a bolt, the end of the body 1 close to the flange body 2 is first inserted into the end of the bolt. During the continuous rotation of the body 1, the wedge-shaped protrusion 5 is screwed into the thread teeth of the bolt, so that the nut and the bolt can be stably fixed and connected to prevent the fixing nut from loosening; the connecting line between the wedge-shaped protrusions 5 is a thread line shape, and the thread line shape is consistent with the thread line of the bolt, so that the wedge-shaped protrusion 5 can be rotated along the thread teeth of the bolt.

[0023] See also Figure 4As shown, the lower part of the flange body 2 is provided with an array of anti-skid protrusions 21, one end of the anti-skid protrusions 21 is closely attached to the lower part of the flange body 2, and the other end is provided with an inclined surface, the inclined surface includes an inclined high surface 211 and an inclined low surface 212, and the thickness of the anti-skid protrusions 21 gradually decreases from one end of the inclined high surface 211 to one end of the inclined low surface 212; there are 2 to 18 anti-skid protrusions.
