Description

Technical Field

[0001] This application belongs to the field of marine oil engineering technology, specifically relating to a pipe clamp and a subsea pipeline support device. Background Technology

[0002] Subsea pipelines refer to pipelines that transport media such as oil, natural gas, water, and chemicals between offshore facilities and between offshore facilities and land terminals. For onshore-to-offshore directional drilling, the entry point can be located on land and the exit point at sea, requiring only barge deployment for support. However, parts of the pipeline remain in the sea and are affected by wind and waves. Current technologies mostly use fixed piles and fixed sleeves mounted on the piles to secure the subsea pipeline. However, the subsea pipeline is still subject to irregular swaying due to undersea currents, especially when swaying up and down, which can easily damage the piles or sleeves and affect operations. Utility Model Content

[0003] To address the technical problem of easy damage in current methods of fixing submarine pipelines, this application provides a pipeline clamp and a submarine pipeline support device.

[0004] In a first aspect of this application, a pipe clamp is provided, comprising: A base, wherein at least one strip groove is provided on the top surface of the base along its length; Two clamping members are disposed opposite to each other on the top surface of the base body, and a first through hole is provided on each clamping member; A connector mates with the strip groove and the first through hole to fix the clamping member to the base; Two positioning components are disposed opposite each other at both ends of the base body. One end of each positioning component is rotatably connected to the base body, and the other end of each positioning component is provided with a connecting part.

[0005] In some embodiments, the top surface of the base is provided with two strip grooves along its length, and the two strip grooves are arranged in parallel; each clamping member is provided with two first through holes, and the two first through holes correspond one-to-one with the two strip grooves.

[0006] In some embodiments, the slot is a through slot, and the connector includes a bolt and a nut, wherein the length of the bolt is greater than the thickness of the base.

[0007] In some embodiments, the clamping member includes a first plate and a second plate, the first plate and the second plate being arranged at an angle, the first through hole being disposed in the second plate, and the first plate having a clamping surface for clamping the pipe.

[0008] In some embodiments, the angle between the first plate and the second plate is 90°.

[0009] In some embodiments, at least one stiffener is provided between the first plate and the second plate.

[0010] In some embodiments, the clamping surface is an arc surface, and the axial direction of the cylindrical surface on which the clamping surface is located is perpendicular to the length direction of the seat.

[0011] In some embodiments, a third plate is further provided at the top of the first plate, and the third plate is located between the two first plates.

[0012] In some embodiments, the connecting part includes two fixed arms, which are disposed opposite to each other on one side of the positioning member. Each fixed arm is provided with at least one second through hole. The positioning member is provided with a pin hole, and the axes of the pin holes of the two positioning members are located on the same straight line. The positioning member cooperates with the pin hole through a pin shaft so that the seat body can rotate relative to the positioning member.

[0013] In a second aspect of this application, a subsea pipeline support device is provided, comprising a pipe sleeve, two support rods and a pipe clamp, each support rod having a plurality of positioning parts along its length, two positioning parts of the pipe clamp being detachably connected to a positioning part of one of the support rods respectively, and the pipe clamp being operable to clamp the pipe sleeve.

[0014] The pipe clamp and subsea pipeline support device provided according to one or more embodiments of this application can adjust the position of the two clamping members on the base body, so that the connecting member passes through the through hole and connects with different positions of the strip groove, thereby changing the distance between the clamping members and clamping the pipe fitting, which is convenient for operators. At the same time, the clamping members can also be adapted to pipe fittings of various specifications. Since the base body and the positioning member can rotate, when the pipe fitting fixed between the two clamping members tends to swing up and down due to the influence of undercurrents or waves, the base body can rotate with the swing of the pipe fitting, thereby reducing the impact of the pipe fitting swing under force and thus reducing the damage rate of the pile body or pipe clamp.

Detailed Implementation

[0017] To enable those skilled in the art to more clearly understand this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0018] This application is described below with reference to the accompanying drawings and specific embodiments: Please see Figure 1 and Figure 2 According to a first aspect of this application, a pipe clamp is provided, including a base 100, two clamping members 200, a connecting member 300, and two positioning members 400. The base 100 is a structural member used to support pipes or pipe structures (hereinafter referred to as pipe fittings), and has a certain strength and corrosion resistance. The top surface of the base 100 is provided with at least one strip groove 110 along its length direction.

[0019] Two clamping members 200 are positioned opposite each other on the top surface of the base 100. Each clamping member 200 has a first through hole 221. A connecting member 300 engages with the strip groove 110 and the first through hole 221 to fix the clamping member 200 to the base 100. By adjusting the position of the two clamping members 200 on the base 100, the connecting member 300 can pass through the through hole and engage with different positions of the strip groove 110, thereby changing the spacing between the clamping members 200 and clamping the pipe fittings. This facilitates operation by the workers. At the same time, the clamping members 200 can also be adapted to various specifications of pipe fittings.

[0020] Two positioning members 400 are disposed opposite each other at both ends of the base 100. One end of the positioning member 400 is rotatably connected to the base 100, and the other end of the positioning member 400 is provided with a connecting part 410. The connecting part 410 is used to connect to the pile fixed on the seabed. The base 100 and the positioning member 400 are rotatable. When the pipe fitting fixed between the two clamping members 200 tends to swing up and down due to the influence of undercurrents or waves, the base 100 can rotate with the swing of the pipe fitting, thereby reducing the impact of the pipe fitting swinging under force and thus reducing the damage rate of the pile or pipe clamp.

[0021] In some embodiments, the top surface of the base 100 has two strip grooves 110 arranged parallel to each other along its length. Each clamping member 200 has two first through holes 221, which correspond one-to-one with the two strip grooves 110. Correspondingly, the number of connecting members 300 is also increased, thereby increasing the tightness of the connection between the base 100 and the clamping member 200, making it less likely for the connection between the base 100 and the clamping member 200 to break under force, and further extending the service life of the pipe clamp.

[0022] In some embodiments, the strip groove 110 is a through groove, and the connector 300 includes a bolt and a nut. The length of the bolt is greater than the thickness of the seat 100. That is, the seat 100 and the clamping member 200 are tightly connected by clamping the seat 100 with the nut and bolt. The connector 300 is easy to obtain and easy to operate.

[0023] In some embodiments, the clamping member 200 includes a first plate 210 and a second plate 220, which are arranged at an angle. A first through hole 221 is provided in the second plate 220, and the first plate 210 has a clamping surface 211 for clamping the pipe. In this configuration, the clamping member 200 has sufficient strength while maintaining a low weight, resulting in less pressure on the positioning member 400. The pressure between the connecting portion 410 of the positioning member 400 and the pile body is also relatively low, further reducing the probability of damage to the pipe clamp. Correspondingly, the length of the strip groove 110 is greater than the outer diameter of the pipe to be clamped, facilitating the adjustment of the position of the first plate 210 on the base 100.

[0024] In some embodiments, at least one stiffener 230 is provided between the first plate 210 and the second plate 220. By providing the stiffener 230, the overall strength of the clamping member 200 is increased, making it less prone to deformation under stress between the first plate 210 and the second plate 220, thereby reducing the probability of damage to the clamping member 200.

[0025] In some embodiments, the angle between the first plate 210 and the second plate 220 is 90°. In this case, the opposing surfaces of the two first plates 210 are parallel, which facilitates the prevention and clamping of pipe fittings. Of course, to further improve the fixing ability of the clamping member 200 on the pipe fitting, the clamping surface 211 is an arc surface, and the axial direction of the cylindrical surface where the clamping surface 211 is located is perpendicular to the length direction of the base 100. That is, the arc surface increases the restraining ability of the clamping surface 211 on the pipe fitting, reducing the probability of the pipe fitting detaching from the clamping member 200. The distance between the ends of the two clamping surfaces 211 furthest from the base 100 is less than the maximum distance between the two clamping members 200.

[0026] In some embodiments, a third plate is further provided at the top of the first plate 210, and the third plate is located between the two first plates 210. That is, by making the distance between the ends of the clamping members 200 farthest from the base 100 smaller than the maximum distance between the two clamping members 200, the locking ability of the clamping members 200 on the pipe is improved, and the possibility of the pipe being dislodged from the clamping members 200 is reduced.

[0027] In some embodiments, the connecting part 410 includes two fixed arms, which are disposed opposite to each other on one side of the positioning member 400. Each fixed arm has at least one second through hole 411. The positioning member 400 has a pin hole, and the axes of the pin holes of the two positioning members 400 are on the same straight line. The positioning member 400 is engaged with the pin hole by a pin shaft 500 so that the seat body 100 can rotate relative to the positioning member 400. One end of the pin shaft 500 is fixedly connected to the seat body 100, and the other end of the pin shaft 500 is rotatably connected to the pin hole. When the two positioning members 400 are fixed to the two piles respectively, the position between the two positioning members 400 remains unchanged. At this time, the pin shaft 500 is not easy to disengage from the pin hole, thus ensuring that the seat body 100 can rotate relative to the positioning member 400. Of course, the pin shaft 500 can also be restricted by providing a plug with a diameter larger than the pin hole at the end of the pin hole near the positioning member 400, so that it will not disengage from the positioning member 400.

[0028] Please see Figures 3-5A second aspect of this application provides a subsea pipeline support device, including a pipe sleeve 600, two support rods 700, and a pipe clamp. Each support rod 700 has multiple positioning portions 710 along its length. Two positioning members 400 of the pipe clamp are detachably connected to a positioning portion 710 of each support rod 700, and the pipe clamp operably clamps the pipe sleeve 600. It is understood that by setting multiple subsea pipeline support devices as described in this embodiment on the seabed, with the pipe clamps on the multiple subsea pipeline support devices located at different positions, the position of the subsea pipeline 900 can be restricted. For example, please refer to... Figure 5 When multiple pipe clamps are set close to the seabed, the pipe clamps can be placed on the seabed, so that the positions of the multiple pipe clamps increase, so that the seabed pipe 900, which is sleeved in the pipe sleeve 600, can run upward to approach the barge 800.
