Airtight platform anchoring device

Abstract

The invention discloses an airtight platform anchoring device. The device comprises a base, a ring seat, a PU temporary clamp, a backing plate, a pressure plate and a cover. The base shape is matchedwith a platform top flange and is detachably fixed to the upper side of the platform top flange, the ring seat is detachably fixed to the upper side of the base, a truncated-type through hole matchedwith the shape of the PU temporary clamp is formed in the ring seat, the outer side of the PU temporary clamp is a truncated type and is arranged in the through hole of the ring seat, the backing plate is disposed on the upper portion of the PU temporary clamp, the backing plate is detachably fixed to the ring seat, the pressure plate is disposed on the upper side of the backing plate and is detachably fixed to the backing plate and the ring seat, the cover is disposed outside the ring seat, the backing plate and the pressure plate, and the lower end of the cover is fixed to the upper side ofthe base. The device integrates the temporary clamp into the platform anchoring device, and not only achieves the temporary fixing effect of the lightweight temporary clamp on a submarine cable, but also achieves the airtightness of the inside of platform anchoring.

Description

technical field [0001] The invention relates to an anchoring device, in particular to an airtight platform anchoring device. Background technique [0002] The invention is applicable to the field of cable fixing. Offshore wind power generation and offshore oil and gas platforms mainly realize power transmission with the outside world through submarine cables. Safe and stable fixing of large-quality submarine cables on platforms is a prerequisite for stable operation of submarine cables. At present, the main way to fix the submarine cable on the platform is to clamp the clamp with threaded fasteners, and then clamp the armored steel wire of the submarine cable. The static friction between the armored steel wire and the clamp is greater than the self-weight of the submarine cable. Cable fixing. [0003] The above common method of fixing the submarine cable on the platform has the following problems: [0004] 1. At present, the commonly used Haval platform platform anchoring ...

Problems solved by technology

[0005] 2. In order to solve the problem of temporarily fixing the submarine cable after it enters the platform, temporary clamps can be used to temporarily fix the submarine cable. At present, the commonly used temporary clamps mainly use the Haval-shaped metal clamp to hold the submarine cable tightly. Complicated and needs to be customized according to the specification of the submarine cable

[0006] 3. For the fan foundation with single-pile entry type, the flange through hole where the submarine cable enters the platform directly comm
