Description

Technical Field

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

[0002] In recent years, the marine environment monitoring technology has been developing continuously, and has developed from single characteristic parameter monitoring to multi-task, multi-region, multi-station, and multi-parameter comprehensive survey and monitoring, providing technical support for the development and utilization of marine resources and the protection of marine ecological environment. At present, jacket-type offshore platforms are widely used in offshore oil development and subsea drilling. Therefore, underwater monitoring equipment is mostly fixed on the jacket with clamps.

[0003] The clamps for fixing underwater monitoring equipment are currently mainly used on smooth conductor frames, and are fixed by embracing and clamping them. Once marine organisms are attached to the conductor frame, the marine organisms attached to the conductor frame must be removed before the clamps are clamped and fixed. Otherwise, a layer of marine organisms will be separated between the clamp and the conductor frame. The marine organisms will die and fall off, which will cause a gap between the clamp and the conductor, and thus the clamp cannot play a stable fixing role. In addition, the current clamp is hinged by at least two hoop plates. After being put on the conductor frame through the opening, the opening needs to be closed with fasteners, and the installation of the clamp is relatively cumbersome. Utility Model Content

[0029] 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.

[0030] In the description of the present invention, it should be understood that the terms "center", "lateral", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0031] 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.

[0032] 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.

[0033] like Figure 1 to Figure 2 As shown, in an illustrative embodiment of the C-type clamp of the catheter frame of the utility model, the C-type clamp of the catheter frame includes a clamp body 1, which is C-shaped with an opening 13 facing downward. The clamp body 1 is arranged from top to bottom as a main body portion 11 and a loading portion 12, the main body portion 11 on the upper side is semicircular, and the loading portion 12 on the lower side has an opening 13, so that it is divided into two hoop plates, and the two hoop plates are respectively connected to the two ends of the main body portion 11. The clamp body 1 is laterally close to the catheter frame, so that the catheter frame enters the clamp body 1 through the opening 13. The inner diameter of the main body 11 and the width of the opening 13 in the clamp body 1 are both 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 thereto and wrap them inside. A mounting seat 2 is installed on the clamp body 1, and the monitoring equipment is fixed on the mounting seat 2.

[0034] In order to fix the pipe frame in the clamp body 1, a plurality of fixing bolts 3 are installed on the clamp body 1. The plurality of fixing bolts 3 are located on the same circumference and are all threadedly connected in the mounting holes provided in the clamp body 1. The inner end of the fixing bolt 3 is provided with a conical breakthrough portion 31. The fixing bolt 3 is rotated to move radially inward, and the breakthrough portion 31 drills the marine organisms attached to the pipe frame as the fixing bolt 3 rotates, thereby penetrating the attachments and pressing on the surface of the pipe frame.

[0035] The multiple fixing bolts 3 are divided into a first fixing bolt 3A located in the main body 11 and a second fixing bolt 3B located in the insertion part 12. The first fixing bolt 3A presses the catheter frame from top to bottom, from left to right or from right to left, and the second fixing bolt 3B presses the catheter frame from bottom to top, so that the multiple fixing bolts 3 are pressed and fixed at multiple angles in the circumferential direction, so that the catheter frame supports the clamp body 1 through the multiple fixing bolts 3, fixes it underwater, and enables the monitoring equipment to stably perform underwater detection. In addition, the second fixing bolt 3B located in the insertion part 12 directly serves as a limiting component to prevent the catheter frame from escaping from the clamp body 1 through the opening 13.

[0036] During the installation and fixation process, there is no need to clean up the attachments. It is only necessary to put the clamp body 1 on the conduit frame with attached marine organisms, and rotate the fixing bolt 3 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 fixing bolt 3 on the conduit frame, and the clamp body 1 is kept fixed and stable. In addition, since the fixing bolt 3 is in contact with the conduit frame, and the fixing bolt 3 and the conduit frame are both metal components, the two are electrically connected, and the monitoring equipment can be connected to the conduit frame by connecting the fixing bolt 3 extending outward, thereby achieving the requirements of cathodic protection measurement such as potential monitoring and stray current monitoring of the conduit frame, and the same cathodic protection as the conduit frame can be obtained, avoiding the corrosion of the clamp and the bolt, and there is no need to remove part of the attachments separately in order to connect to the conduit frame electrically, which improves the convenience of detection connection. The clamp body 1 and the fixing bolt 3 are made of the same material as the conduit frame to avoid additional corrosion (galvanic corrosion).

[0037] In the above-mentioned schematic embodiment, the clamp body 1 of the C-type clamp of the catheter frame is C-shaped and can be directly inserted into the catheter frame laterally. Even if the catheter frame enters the clamp body 1 through the opening 13, the clamp body 1 is wrapped around the catheter frame. Compared with the original clamp structure that requires fasteners to open and close, the installation operation is easier; by threading the clamp body 1 with the fixing bolts 3 that can penetrate the marine organisms attached to the catheter frame, the clamp body 1 is fixedly installed on the catheter frame through multi-point pressure and fixation of multiple fixing bolts 3, and the monitoring equipment fixedly installed on the mounting seat 2 is stably supported. There is no need to clean the marine organisms attached to the catheter 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 catheter frame through the fixing bolts 3, which is convenient for the monitoring equipment to detect the catheter frame, solving the problem that the current clamp needs to be cleaned of marine organisms before it can be stably installed and the installation operation is cumbersome.

[0038] Among them, at least four first tightening bolts 3 are arranged and are evenly distributed on the main body 11, so that when any two of the first tightening bolts 3A are loosened, the remaining first tightening bolts 3A and second tightening bolts 3B can be distributed on an arc greater than or equal to 180 degrees, meeting the requirements of multi-angle pressing and fixing, and the clamp body 1 is kept stable by the tightening bolts 3.

[0039] In some embodiments, the second fastening bolt 3B is inclined toward one side of the main body 11 relative to the inner wall of the insertion portion 12, so that it acts as a barb to clamp and fix the catheter frame in the clamp body 1, thereby increasing the limiting effect of the second fastening bolt 3 and improving the stability of the catheter frame in the clamp body 1.

[0040] In some embodiments, both sides of the insertion portion 12 are provided with second fixing bolts 3B, so that after the second fixing bolts 3B are tightened inwardly, the distance between the second fixing bolts 3B on both sides is small, ensuring that the catheter frame will not fall out of the clamp body 1 between the two, further improving the stability of the clamp body 1.

[0041] In some embodiments, the outer end of the set bolt 3 is provided with a handle 4, and the handle 4 is ring-shaped. The set bolt 3 is provided with a handle 4, which is convenient for the mechanical arm of the ROV to hold the handle 4, and then to rotate the set bolt 3, thereby realizing the mechanized operation of the underwater fixation of the clamp body 1. The handle 4 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 4, and then rotate it to drive the handle 4 to rotate, thereby realizing the rotation operation of the set bolt 3, 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.

[0042] In some embodiments, the end surface of the breakthrough portion 31 is a plane or an arc surface.

[0043] When the end surface of the breakthrough portion 31 is an arc surface, the end of the breakthrough portion 31 is hemispherical, which ensures that the breakthrough portion 31 can drill through the attachment and prevents the breakthrough portion 31 from damaging the catheter frame.

[0044] When the end surface of the breakthrough portion 31 is a plane, the side walls on both sides of the breakthrough portion 31 are provided with cut surfaces so as to make it look like a flat screwdriver head. The breakthrough portion 31 is in a cone shape as a whole, and the flat end drills through the attachment and sweeps it off, not only drilling holes 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 on the catheter frame, and after drilling through the attachment, the end surface of the breakthrough portion 31 can be attached to the surface of the catheter frame to avoid damaging the catheter frame.

[0045] In some embodiments, grooves 14 are provided on both the inner and outer surfaces of the clamp body 1 to form two first stiffening ribs 15 on both sides of the grooves 14. Multiple grooves 14 are provided from one end to the other end of the clamp body 1, and second stiffening ribs 16 are formed between adjacent grooves 14.

[0046] If the strength of the clamp body 1 is insufficient, when the set bolt 3 is tightly pressed on the catheter frame, the reaction force of the pressing force acts on the clamp body 1 through the set bolt 3, causing the clamp body 1 to deform outward, and the set bolt 3 moves outward accordingly, so that it cannot be firmly pressed on the catheter frame. In addition, the clamp body 1 is not a closed structure, and the opening 13 on one side will open as it deforms, causing the clamp body 1 to loosen or even fall off from the catheter frame. Therefore, the first reinforcing rib and the second reinforcing rib 16 can enhance the strength of the clamp body 1, prevent the clamp body 1 from deforming, and then keep the set bolt 3 firmly pressed on the catheter frame. The first reinforcing rib and the second reinforcing rib 16 can reinforce the clamp body 1 in two directions to further improve its structural strength.

[0047] In some embodiments, a marking coating (not shown in the drawings) is provided on the surface of the set bolt 3 , 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 3 .

[0048] When the set bolt 3 is rotated to move radially inward, the length of the set bolt 3 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 3 located on the inner side of the clamp body 1, thereby preventing the set bolt 3 from moving excessively inward and causing deformation of the catheter frame.

[0049] The set bolt 3 is provided with a limiting nut 5 and a locking nut 6. When the breakthrough portion 31 of the set bolt 3 is pressed against the surface of the pipe frame, the locking nut 6 presses the limiting nut 5 against the side wall outside the clamp body 1. The limiting nut 5 and the locking nut 6 reinforce the set bolt 3 to prevent it from rotating and loosening by itself, keep it firmly pressed against the pipe frame, and maintain the stable installation of the clamp body 1.

[0050] In some embodiments, the second fixing bolt 3 is replaced with a staple 7, and the staple 7 is inclined toward one side of the main body 11 relative to the inner wall of the insertion portion 12, so that it acts as a barb to clamp and fix the catheter frame in the clamp body 1. Compared with the fixing bolt 3, the staple 7 has a simpler structure, and the clamp body 1 only needs to be laterally sleeved on the catheter frame without operating the staple 7, making it easier to install and fix the clamp body 1. In addition, the structure of the staple 7 is located on the inner side of the clamp body 1 as a whole, and does not need to extend to the outer side of the clamp body 1, which provides more space for the outer side of the clamp body 1 to set the mounting seat 2, thereby installing more monitoring equipment.

[0051] In order to allow the catheter rack to smoothly pass over the staple 7 and enter the clamp body 1, the staple 7 can be an elastic member. When the clamp body 1 enters the opening 13, the staple 7 is pushed outward. After the catheter rack passes over the staple 7, the staple 7 is reset inward by its elasticity, so that it is located at the lower side of the catheter rack to limit its position.

[0052] The clamp is inclined toward the main body 11 , so that when the catheter frame is installed, one side thereof forms an inclined surface, guiding the catheter frame to pass over the clamp 7 , thereby improving the smoothness of the installation of the catheter frame.

[0053] In some embodiments, when the staple 7 is a rigid member, the outer end of the staple 7 is hinged on the loading portion 12, and the inner end extends into the opening 13. A torsion spring is installed on the outer end of the staple 7, and the surface of the staple 7 away from the main body 11 is attached to the limit seat provided on the loading portion 12 under the elastic force of the torsion spring.

[0054] When the clamp body 1 enters the opening 13, it pushes the nail 7 outwards to make it swing outwards. After the catheter frame passes over the nail 7, the deformed torsion spring pushes the nail 7 inwards through its elastic force, making the nail 7 swing inwards and reset, so that it is under the catheter frame to limit its position.

[0055] In some embodiments, a plurality of teeth 8 are provided on one side of the inner end of the staple 7 close to the main body 11. The teeth 8 can penetrate into the marine organism when the staple 7 clamps the catheter frame, thereby preventing the staple 7 from sliding and causing the catheter frame to pass over the staple 7 and escape from the clamp body 1, thereby improving the fixing stability.

[0056] 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.

[0057] 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.
