Detailed implementation manners

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1-6 , a rubber protection device, comprising: a rubber protection pad 1 and an embedded steel plate 2 integrally formed with the rubber protection pad 1. The embedded steel plate 2 is provided with holes for passing bolts. A sealing component 4 and an adjusting component 3 are further arranged on the rubber protection pad 1. The sealing component 4 includes a sealing plate 41 slidably arranged inside the rubber protection pad 1, a comb-shaped plate 42 and a second limit block 45 respectively fixed on both side surfaces of the sealing plate 41, an auxiliary rack 43 fixedly installed on the side surface of the comb-shaped plate 42, and an auxiliary gear 44 rotatably arranged inside the rubber protection pad 1. The auxiliary gear 44 is also meshed with the auxiliary rack 43; a receiving hole for receiving the bolt head is formed on the rubber protection pad 1, and the hole surface area of the receiving hole is smaller than the surface area of the sealing plate 41. Such a design ensures that the sealing plate 41 can block the receiving hole, thereby avoiding the situation that sea water splashes on the bolt head inside it.

[0025] The adjusting assembly 3 includes a central shaft 33 rotatably arranged inside the rubber gasket 1, a turntable 31 fixedly connected to the central shaft 33, a ball head rod 38 slidably arranged inside the central shaft 33, a connecting plate 36 fixedly installed on the ball head rod 38, a first spring 37 fixedly connected to the connecting plate 36, the end of the first spring 37 away from the connecting plate 36 being fixedly connected to the central shaft 33, a connecting rod 35 fixedly connected to the ball head rod 38, a stop block 34 fixedly connected to the connecting rod 35, a slider 39 slidably arranged on the turntable 31, a sliding button 32 and a spherical protrusion 312 respectively fixedly arranged on both side surfaces of the slider 39, the outer surface of the spherical protrusion 312 being tangent to the ball head end of the ball head rod 38, a first limiting block 310 fixedly installed on the slider 39, and a second spring 311 fixedly connected to the slider 39, the end of the second spring 311 away from the slider 39 being fixedly connected to the turntable 31. The central shaft 33 is also fixedly connected to an auxiliary gear 44, and the central shaft 33 is also rotatably connected to an embedded steel plate 2. The stop block 34 is designed in an annular structure, and friction lines are arranged on the side surface of the stop block 34. A chute for passing through the connecting rod 35 is formed on the central shaft 33, and both ends of the chute are closed, ensuring that the connecting rod 35 can slide along with the sliding of the ball head rod 38, and avoiding the phenomenon of mutual interference when each structure in the overall device operates.

[0026] Working principle: After fixing the embedded steel plate 2 integrally formed with the rubber protection pad 1 in the offshore foundation column by bolts, at this time, the bolt head is located in the receiving hole on the rubber protection pad 1. Push the sliding button 32 on the turntable 31, and the slider 39 fixedly connected to the sliding button 32 slides synchronously on the turntable 31. The spherical protrusion 312 fixed on the slider 39 no longer contacts the ball head end of the ball head rod 38. The connecting plate 36 fixed on the ball head rod 38 is further connected to the central shaft 33 through the first spring 37. Therefore, under the action of the first spring 37, the ball head rod 38 will slide towards the turntable 31. The stop block 34 fixedly connected to the ball head rod 38 through the connecting rod 35 slides synchronously. At this time, the stop block 34 no longer contacts the embedded steel plate 2. After driving the turntable 31 to rotate through the sliding button 32, the central shaft 33 fixedly connected to the turntable 31 rotates synchronously, and the auxiliary gear 44 fixedly connected to the central shaft 33 rotates accordingly. The auxiliary gear 44 meshes with the auxiliary rack 43 fixed on the comb-shaped plate 42, and the sealing plate 41 is fixed on the comb-shaped plate 42. Therefore, after the auxiliary gear 44 rotates, the sealing plate 41 can be driven to slide to close the receiving hole on the rubber protection pad 1, preventing sea water from splashing on the bolt head in the receiving hole. Subsequently, release the sliding button 32. Under the action of the second spring 311 fixedly connected to the sliding button 32 and the turntable 31 at both ends, the sliding button 32, the slider 39 and the spherical protrusion 312 can be driven to slide towards the ball head rod 38, so as to squeeze the ball head rod 38 to slide inside the central shaft 33 through the spherical protrusion 312, and then the stop block 34 contacts the embedded steel plate 2 again. At this time, the friction lines on the stop block 34 cooperate with the embedded steel plate 2 to form a frictional force that can limit the rotation of the central shaft 33 and the auxiliary gear 44, thereby locking the position of the sealing plate 41.

[0027] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
