Description

Technical Field

[0001] The utility model belongs to the technical field of underwater monitoring equipment, and in particular relates to a conductor frame annular clamp device. Background Art

[0002] In marine engineering, offshore platforms are usually supported by underwater jackets. These jackets not only bear the weight of the platform, but are also used to install various underwater monitoring equipment. The monitoring equipment needs to be installed on the jacket through clamps and relies on the clamping force of the clamps to maintain stability. However, the clamp design in the prior art has certain limitations, especially when marine organisms are attached to the surface of the jacket.

[0003] Traditional clamp design requires that the surface of the jacket must be smooth and clean to ensure that the clamp can tightly clamp the jacket and achieve stable fixation of the equipment. However, in the actual marine environment, the jacket is immersed in seawater for a long time and is prone to various marine organisms such as shellfish and algae. These marine organisms will form a thick coating on the jacket surface. If it is not removed, it will affect the clamping effect of the clamp.

[0004] When the clamp is installed on a conductor frame covered with marine growth, the marine growth will act as a barrier between the clamp and the conductor frame, causing the clamp to be unable to closely contact the conductor frame. Once the marine growth dies and decomposes, a gap will form between the clamp and the conductor frame, causing the clamp to loosen, and eventually causing the monitoring equipment to lose its stable fixing effect. Therefore, the existing technology requires that the marine growth on the surface of the conductor frame must be thoroughly removed before installing the clamp, which not only increases the complexity and time cost of the installation work, but may also cause wear and damage to the conductor frame.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] The terms "first", "second", and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Thus, a feature defined as "first", "second", and "third" may explicitly or implicitly include one or more of the features.

[0028] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] like Figure 1 to Figure 2 As shown, in an illustrative embodiment of the annular clamp device of the catheter frame of the utility model, the annular clamp device of the catheter frame includes an annular clamp body 1, and an opening 11 is provided on one side of the clamp body 1. When the opening 11 is opened, the catheter frame can enter the clamp body 1 through the opening 11, so that it is sleeved on the clamp body 1. A fastener 2 is installed on the clamp body 1. When the fastener 2 closes the opening 11, the clamp body 1 is surrounded by the catheter frame so that it cannot radially escape. A mounting seat 3 is installed on the clamp body 1 to fix the monitoring equipment.

[0030] A plurality of set bolts 4 are mounted on the clamp body 1. The set bolts 4 are threadedly connected to the mounting holes provided in the clamp body 1, and the inner ends thereof are provided with conical breakthrough portions 41. The set bolts 4 are rotated to move radially inward, and the breakthrough portions 41 drill the marine organisms attached to the jacket as the set bolts 4 rotate, thereby penetrating the attached organisms and pressing on the surface of the jacket.

[0031] The inner diameter of the clamp body 1 is larger than the outer diameter of the marine organisms attached to the catheter frame, ensuring that the clamp body 1 can connect the catheter frame to the marine organisms attached to it and wrap around its inner side. Multiple tightening bolts 4 are pressed and fixed at multiple angles, so that the catheter frame supports the clamp body 1 through multiple tightening bolts 4, fixes it underwater, and enables the monitoring equipment to perform stable detection underwater. During the installation and fixing process, there is no need to clean the attachments additionally. It is only necessary to put the clamp body 1 on the catheter frame with the marine organisms attached, and rotate the tightening bolts 4 to make it drill through the attachments to achieve the fixation of the clamp body 1. When the marine organisms die and fall off, it will not affect the pressure of the tightening bolts 4 on the catheter frame, and the clamp body 1 will be kept fixed and stable. In addition, since the fixing bolt 4 is in contact with the conduit frame, and both the fixing bolt 4 and the conduit frame are metal components, the two are electrically connected, and the monitoring equipment can be electrically connected to the conduit frame by connecting the fixing bolt 4 extending outward, thereby achieving the requirements of cathodic protection measurement such as potential monitoring and stray current monitoring of the conduit frame, and can obtain the same cathodic protection as the conduit frame, avoiding corrosion of the clamp and bolt, and there is no need to remove part of the attachment separately for electrical connection with the conduit frame, thereby improving the convenience of detection connection. The clamp body 1 and the fixing bolt 4 are made of the same material as the conduit frame to avoid additional corrosion (galvanic corrosion).

[0032] In the above-mentioned schematic embodiment, the annular clamp device of the conductor frame is threadedly installed on the clamp body 1 with a fixing bolt 4 that can penetrate the marine organisms attached to the conductor frame, thereby fixing the clamp body 1 on the conductor frame through multi-point pressure holding by multiple fixing bolts 4, and stably supporting the monitoring equipment fixedly installed on the mounting seat 3. There is no need to clean the marine organisms attached to the conductor frame, and the falling of the marine organisms will not affect the stability of its installation. In addition, the monitoring equipment can be electrically connected to the conductor frame through the fixing bolts 4, which is convenient for the monitoring equipment to detect the conductor frame, thereby solving the problem that the current clamp needs to be cleaned of marine organisms before it can be stably installed.

[0033] In some embodiments, a plurality of fixing bolts 4 are evenly arranged on the same circumference, and the number of the fixing bolts 4 is at least 6.

[0034] like Figure 2 As shown, taking the uniform distribution of 6 set bolts 4 as an example, when one set bolt 4 is loosened, the remaining five set bolts 4 maintain a tight pressure on the catheter frame, and the circumferential range of the distribution of the five set bolts 4 is greater than 180 degrees; when two non-adjacent set bolts 4 are loosened, the remaining four set bolts 4 maintain a tight pressure on the catheter frame, and the circumferential range of the distribution of the four set bolts 4 is greater than 180 degrees; when two adjacent set bolts 4 are loosened, the remaining four set bolts 4 maintain a tight pressure on the catheter frame, and the circumferential range of the distribution of the four set bolts 4 is equal to 180 degrees. The tight pressing set bolts 4 ensure that their distribution range is greater than or equal to 180 degrees, which can meet the requirements of multi-angle pressing and fixing, and the clamp body 1 is kept stable by the set bolts 4. Therefore, the six tightening bolts 4 are evenly distributed, which can ensure that the clamp body 1 is stably fixed when any two of the tightening bolts 4 become loose, thereby improving the redundancy of reliability. In addition, the space between adjacent tightening bolts 4 is large, which is convenient for accommodating the monitoring equipment installed on the mounting base 3, thereby avoiding the monitoring equipment from hindering the radial movement of the tightening bolts 4.

[0035] The number of the fixing bolts 4 is further increased, and the distribution density thereof is increased. Although the accommodation space of the monitoring equipment is reduced, the number of the fixing bolts 4 that can be allowed to loosen to maintain the stable fixation of the clamp body 1 can be further increased.

[0036] In some embodiments, the outer end of the set bolt 4 is provided with a handle 5, and the handle 5 is ring-shaped. The set bolt 4 is provided with a handle 5, which is convenient for the mechanical arm of the ROV to hold the handle 5, and then to rotate the set bolt 4, thereby realizing the mechanized operation of the underwater fixation of the clamp body 1. The handle 5 is ring-shaped, and the mechanical arm of the ROV does not need to be provided with a movable finger structure, but only needs to be provided with a hook-shaped structure to hook the handle 5, and then rotate it, so as to drive the handle 5 to rotate and realize the rotation operation of the set bolt 4, thereby simplifying the structural complexity of the ROV mechanical arm, so that the ROV with a simple structure can also complete the underwater fixation operation of the clamp body 1.

[0037] The clamp body 1 is composed of at least two arc-shaped hoop plates 12, which are connected in series by hinges. The two hoop plates 12 at both ends of the opening 11 are connected by fasteners 2, so that each hoop plate 12 is connected to form a closed loop clamp body 1. The fastener 2 is a detachable component, and a fastening bolt with a handle 5 can be used. A first fastening seat 13 is arranged on the hoop plate 12 at one end of the opening 11, and a movable seat is hinged on the first fastening seat 13. The fastening bolt is threadedly connected to the movable seat. A second fastening seat is arranged on the hoop plate 12 at the other end of the opening 11. The fastening bolt is laterally inserted into the connecting groove 15 provided in the second fastening seat 14. By tightening the fastening bolt, the first fastening seat 13 and the second fastening seat 14 can be tightened toward each other to achieve the closure of the opening 11. The swinging and rotating of the fastening bolt can be completed by the mechanical arm of the ROV, so that the installation of the clamp device can be performed by remote operation of the ROV, thereby improving the convenience of installation.

[0038] In some embodiments, the end surface of the breakthrough portion 41 is a plane or an arc surface.

[0039] When the end surface of the breakthrough portion 41 is an arc surface, the end of the breakthrough portion 41 is hemispherical, which ensures that the breakthrough portion 41 can drill through the attachment and prevents the breakthrough portion 41 from damaging the catheter frame.

[0040] When the end surface of the breakthrough portion 41 is a plane, the side walls on both sides of the breakthrough portion 41 are provided with cut surfaces so as to be shaped like a flat screwdriver head. The breakthrough portion 41 is in a cone shape as a whole, and the flat end drills through the attachment and sweeps it off, not only drilling a hole in the attachment, but also having a certain ability to remove the attachment, exposing the surface of the catheter frame to a certain extent, facilitating contact measurement items of the catheter frame, and after drilling through the attachment, the end surface of the breakthrough portion 41 can be attached to the surface of the catheter frame to avoid damaging the catheter frame.

[0041] In some embodiments, a first limiting ring 42 is installed on the fastening bolt 4 . The first limiting ring 42 is located on the inner side of the clamp body 1 and is spaced apart from the inner side wall of the clamp body 1 .

[0042] When the clamp device needs to change the fixed position, the set bolt 4 needs to be rotated in the opposite direction, so as to move radially outward and away from the pipe frame. The clamp body 1 limits the axial movement of the set bolt 4 outward through the first limiting ring 42, so as to prevent the set bolt 4 from moving too much outward and falling out of the mounting hole, and maintain its connection with the clamp body 1. Therefore, when the clamp body 1 is mounted on the pipe frame at the new position, the set bolt 4 can be directly rotated to penetrate the attachment to complete the fixation of the new position, which is convenient to operate.

[0043] In some embodiments, a second limiting ring 43 is installed on the fastening bolt 4 . The second limiting ring 43 is located on the outside of the clamp body 1 and is spaced apart from the side wall of the outside of the clamp body 1 .

[0044] The clamp body 1 limits the axial outward movement of the set bolt 4 through the second limit ring 43 to prevent the set bolt 4 from extending too long inward, thereby preventing the set bolt 4 from pushing the catheter frame up and deforming, thereby ensuring the stable support of the catheter frame to the platform.

[0045] In some embodiments, a marking coating (not shown in the drawings) is provided on the surface of the set bolt 4 , and the marking coating is divided into a plurality of marking portions of the same width and different colors in sequence along the axial direction of the set bolt 4 .

[0046] When the set bolt 4 is rotated to move radially inward, the length of the set bolt 4 extending into the inner side of the clamp body 1 can be determined by observing the number and color of the markings on the set bolt 4 located on the inner side of the clamp body 1, thereby avoiding excessive inward movement of the set bolt 4 and causing deformation of the catheter frame.

[0047] In some embodiments, a limiting nut 6 and a locking nut 7 are installed on the set bolt 4. When the breakthrough portion 41 of the set bolt 4 is pressed on the surface of the pipe frame, the locking nut 7 presses the limiting nut 6 on the side wall outside the clamp body 1. The limiting nut 6 and the locking nut 7 reinforce the set bolt 4 to prevent it from rotating and loosening by itself, keep it firmly pressed on the pipe frame, and maintain the stable installation of the clamp body 1.

[0048] In some embodiments, two reinforcing ribs 16 are provided on the inner side wall of the clamp body 1, and the two reinforcing ribs 16 are respectively located on the upper and lower sides of the set bolt 4. If the strength of the clamp body 1 is insufficient, when the set bolt 4 is tightly pressed on the catheter frame, the reaction force of the pressing force acts on the clamp body 1 through the set bolt 4, causing the clamp body 1 to deform outward, and the set bolt 4 moves outward accordingly, so that it cannot be firmly pressed on the catheter frame. Therefore, the reinforcing ribs 16 can enhance the strength of the clamp body 1, prevent the clamp body 1 from deforming, and then maintain the firm pressing of the set bolt 4 on the catheter frame. The two reinforcing ribs 16 are distributed up and down, which fully improves the overall strength of the clamp body 1.

[0049] In some embodiments, multiple mounting seats 3 are installed along the circumferential direction so that each mounting seat 3 is distributed at different angular positions. By selectively installing the monitoring equipment on different mounting seats 3, the monitoring equipment can be oriented in different directions, so that the monitoring equipment can be in the best installation position to meet the detection purposes in different directions, or eliminate the obstruction of the underwater structure to maintain the communication stability of the monitoring equipment.

[0050] Finally, it should be noted that: the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0051] The above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the utility model, which should be included in the scope of the technical solution for which protection is requested in the utility model.
