Description

Technical Field

[0001] The utility model relates to the technical field of J-type pipe center clamps, in particular to an embedded J-type pipe center clamp. Background Art

[0002] With the continuous development of marine resources, different types of offshore platforms have gradually increased. As an energy and signal transmission device for offshore platforms, submarine cables play an important role in ensuring the safe production of offshore platforms. In the prior art, submarine cables generally enter offshore platforms through J-shaped pipes. Under the long-term scouring of ocean currents, the shaking of submarine cables is likely to form a scouring area on the seabed surface below the offshore platform.

[0003] In a current embedded J-type pipe center clamp in the prior art, when a submarine cable is inserted into a J-type pipe, friction will occur between the cable and the J-type pipe during the pulling process, which may cause damage to the cable due to friction. In this case, it is necessary for personnel to dive for maintenance, which increases the installation and use costs. Moreover, the clamp cannot be adjusted according to the widths of different cables, with large limitations and poor practicability. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problems in the prior art that when a submarine cable is inserted into a J-type pipe, friction will occur between the cable and the J-type pipe during the pulling process, which may cause damage to the cable due to friction. In this case, it is necessary for personnel to dive for maintenance, which increases the installation and use costs, and the clamp cannot be adjusted according to the widths of different cables, with large limitations. The utility model provides an embedded J-type pipe center clamp.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: An embedded J-type pipe center clamp includes a first clamping plate and a second clamping plate. The second clamping plate is arranged below the first clamping plate. A cable groove is formed through the first clamping plate and the second clamping plate. The first clamping plate and the second clamping plate are fixed by a plurality of fastening bolts. Threaded studs are connected inside both the first clamping plate and the second clamping plate. One ends of the two studs inside the first clamping plate and the second clamping plate are rotatably connected with pressing plates.

[0006] Preferably, limiting blocks are fixed at both ends of the pressing plate, and limiting grooves matching the limiting blocks are formed at both ends of the inner walls of the first clamping plate and the second clamping plate.

[0007] Preferably, a first slope is arranged at one end of the first clamping plate and the second clamping plate, and a second slope is arranged at the other end of the first clamping plate and the second clamping plate.

[0008] Preferably, screw grooves matching the stud bolts are formed in both the first clamping plate and the second clamping plate, and second hexagonal grooves are formed at one ends of the two stud bolts located outside the first clamping plate and the second clamping plate.

[0009] Preferably, a plurality of first mounting grooves and second mounting grooves matching the fastening bolts are respectively formed through the sides of the first clamping plate and the second clamping plate.

[0010] Preferably, a first hexagonal groove is formed at the top of the fastening bolt, and third slopes are formed on both sides of one ends of the two pressing plates facing each other.

[0011] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0012] 1. In the present utility model, a cable groove is formed between the first clamping plate and the second clamping plate, which facilitates the placement of the cable therein. Subsequently, the fastening bolt provides fastening between the first clamping plate and the second clamping plate, thereby facilitating the wrapping of the cable by the first clamping plate and the second clamping plate. Moreover, the ends of the first clamping plate and the second clamping plate are respectively provided with a first slope and a second slope. Through the guiding cooperation of the first slope and the second slope, it is beneficial to insert the bell mouth of the J-shaped pipe into the J-shaped pipe during the installation process, avoiding contact friction between the cable and the inner wall of the J-shaped pipe during the pulling activity and damage, and at the same time avoiding the use of divers, thereby reducing the installation cost and risk and providing complete protection for the cable by the fastening bolt.

[0013] 2. In the present utility model, by rotating the two stud bolts by the user, the two pressing plates move towards each other under the limitation of the limiting block and the limiting groove, so as to clamp and fix the cable placed in the cable groove. This device achieves the clamping effect by adjusting the distance between the two pressing plates, enabling it to be adjusted according to the width of the cable, with stronger practicability. And through the setting of the fastening bolt, the first clamping plate and the second clamping plate are of an installation and disassembly form, ensuring the convenience of installation and disassembly.
