The invention will be described in detail with reference to the following embodiments with reference to the attached drawings.
A wellhead anti-falling net structure of an ocean platform is shown in figures 1 to 5 and comprises a support ring 1 and a safety net 2; the support ring is arranged on an oil containment boom 4 of the wellhead square cover 3;
the safety net is arranged on the lower side of the support ring through a hanging mechanism 5; the supporting ring is provided with a handheld structure 6, the handheld structure comprises openings or handles symmetrically arranged on the supporting ring, and the supporting ring can be conveniently carried and can be conveniently installed and fixed on the oil containment boom;
the support ring comprises a support part 7 and a straight cylinder part 8 on the lower side of the support part; the oil containment boom is of a vertically-arranged cylindrical structure, the straight cylinder part of the support ring is positioned in the oil containment boom, and the top of the oil containment boom props against the lower surface of the support part;
the safety net comprises a net body 9 and side ropes 10 arranged on the periphery of the net body, wherein the side ropes are arranged in a ring shape along the circumferential direction of the support ring; the hanging mechanism comprises a plurality of hooks which are arranged at intervals along the circumferential direction of the support ring. Usually, each of the hooks is arranged uniformly with the axis of the support ring as the center.
The net body comprises a plurality of transversely and longitudinally staggered net ropes 12, and the tail ends of the net ropes are connected to the side ropes. By way of example, the connection between the ends of the net ropes and the side ropes has two types, one is a fixed connection structure 13, and the other is a movable connection structure 11, and the fixed connection structure and the movable connection structure are arranged on the side ropes in a staggered manner.
The support ring for fixing the safety net is made of stainless steel, and the support part of the support ring is placed on the oil fence of the large wellhead cover. The safety net is made of polyethylene net, and has high strength, light weight, high fire resistance and high corrosion resistance. For example, the diameter of the net rope of the net body is more than or equal to 6 mm, the diameter of the side rope is more than or equal to 8 mm, the diameter of the mesh is less than or equal to 100 mm, and the static bearing capacity can reach more than 200 kg.
In an alternative embodiment, when the movable connection structure is adopted, as shown in fig. 6, the side rope passes through a fastening buckle 14 formed at the tail end of the net rope, and the fastening buckle is in sliding fit with the net rope, that is, the connection point of the tail end of the net rope and the side rope is a non-fixed position; the fixed connection structure is that the tail end of the net rope is directly tied to the side rope or directly locked and fixed on the side rope through a connecting piece, and the connection point of the tail end of the net rope and the side rope is a fixed position.
Usually, the hook is hooked on the fixed connection structure part, so that the movable connection structure can be ensured to have a movable space and is not limited by the connection position of the hook.
Each terminal and the limit rope of net rope is connected, adopt fixed connection structure and movable connection structure staggered arrangement's form, after safety net (dictyosome part) is carried, the net rope edgewise rope that allows movable connection structure produces certain slip, with the adaptation atress needs, buffer capacity obtains the reinforcing, and fixed connection structure's coupling part, can be spacing to the terminal production of movable net rope, it is too big to restrict its amount of movement, it is stable to keep overall structure, when having personnel or object to fall, safety net overall stability is good, it is stronger than ordinary fixed knot structure's safety net shock resistance and buffer capacity, it is not fragile, and the security is better.
The hanger comprises a vertical hanging part 15 and a hanger body part 16 below the hanging part, the hanging part and the hanger body part are generally in an integrally formed structure, the upper end of the hanging part of the hanger is welded and fixed on the straight barrel part, the structural stability is good, and the strength is guaranteed. In the invention, the side rope is hooked by the hook, so that the safety net is detachably connected with the support ring, and the safety net is convenient to install and replace. In addition, in order to improve the safety of the hooking side rope, in an optional embodiment, a safety clip 17 can be arranged between the suspending part and the hook body part to prevent the safety net from accidentally slipping off.
In an alternative embodiment, as shown in fig. 7, the hooks include a long hook and a short hook, wherein the length of the hanging part of the long hook 19 is greater than the length of the hanging part of the short hook 18 (the shapes and sizes of the structural parts of the long hook and the short hook are completely the same), and the long hook and the short hook are arranged on the support ring in a staggered manner, so that the border rope of the safety net is hooked on each long hook or hooked on each short hook according to the use requirement on site to adapt to different working conditions and installation requirements, and the hook has stronger universality and better use effect.
By way of example, when the oil containment boom (and the attachment structure on the upper side of the oil containment boom) is high, the safety net is fixed on the long hook, and when the oil containment boom is low, the safety net can be hooked and fixed on the short hook.
The safety net is reasonable in structural design, convenient to use, good in protection effect and beneficial to safety management, and the side ropes are hooked by the hooks, so that the safety net is detachably connected with the support ring, and the safety net is convenient to install and replace. The invention creates the safety net with better overall stability, stronger impact resistance and buffer capacity and better safety compared with the common safety net with a fixed structure when the tail ends of all net ropes of the safety net are connected with the side ropes and the connection form of the net ropes and the side ropes is designed into a movable connection structure-fixed connection structure which is arranged in a staggered way.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and should not be taken as limiting the invention, so that any modifications, equivalents, improvements and the like, which are within the spirit and principle of the present invention, should be included in the scope of the present invention.
