Technical Field

[0001] The utility model relates to the technical field of pipeline grounding saddles, in particular to a novel glass fiber reinforced plastic pipeline grounding saddle. Background Art

[0002] At present, the installation of grounding wires used for grounding saddles for FRP pipelines is relatively complicated. The middle part of the saddle is slotted to embed the grounding bolts in the saddle, and a through hole is opened on the side of the saddle to connect with the slot. When grounding, the grounding wire needs to be welded to the stainless steel washer, and the washer is fixed to the grounding bolt in the slot with a nut. The steel wire rope is led out through the through hole, and the slot is sealed with glue. Finally, the grounding saddle is glued to the FRP pipeline to achieve grounding continuity. The installation method of the grounding end on the other side is the same.

[0003] Under the existing structure, the specification of the grounding wire is limited. The specification of the grounding wire cannot be larger than the diameter of the through hole. If there is an insulating layer outside the grounding wire, it is not convenient to lead it out from the through hole. It cannot be used when some projects have special requirements for the cross section and insulation layer of the grounding wire. In addition, the installation of the existing structure grounding wire requires welding and gluing, which is complicated.

[0004] In view of the above problems, the utility model designs and manufactures a novel glass fiber reinforced plastic pipeline grounding saddle to overcome the above defects. Utility Model Content

[0030] In order to facilitate understanding by those skilled in the art, the present invention is further described below in conjunction with the accompanying drawings.

[0031] like Figures 1 to 4 As shown, a new type of FRP pipeline grounding saddle includes a main saddle 1. A clamping device 3 is integrally molded on the side of the main saddle 1 away from the FRP pipe. The clamping device 3 specifically includes a connecting portion and a locking portion 31. The locking portion 31 is arranged in a direction away from the main saddle 1. The locking portion 31 can be connected to the grounding wire 5. The connecting portion is integrally molded inside the main saddle 1.

[0032] By integrally molding the clamping device 3 on the side of the main saddle 1 away from the fiberglass reinforced plastic pipe and directly connecting the grounding wire 5 to the clamping device 3, the main saddle 1 can be grounded. Compared with the traditional connection method of the grounding wire 5, the entire grounding structure of the utility model is simpler and easier to operate, reducing the workload of the installer.

[0033] Specifically, the locking portion 31 is in the shape of a tapered cylinder, and the large diameter section of the locking portion 31 is connected to the connecting portion. The circumference of the tapered cylindrical locking portion 31 is provided with a plurality of radial hollow grooves 35, and the hollow grooves 35 extend from the small diameter end of the locking portion 31 to the large diameter end of the locking portion 31, so that the locking portion 31 can be expanded outward by external force, so as to facilitate the introduction of grounding wires 5 with different wire diameters. The locking portion 31 is provided with an external thread, and a locking nut 6 is externally screwed on the locking portion 31, and the inner wall of the locking nut 6 matches the tapered surface of the locking portion 31.

[0034] To further ensure the standard requirements of the grounding wire 5 in different situations, the locking portion 31 is preferably capable of threading locking nuts 6 with different inner diameters. Specifically, when a thicker grounding wire 5 is used, a locking nut 6 with a larger inner diameter is used; when a thinner grounding wire 5 is used, a locking nut 6 with a smaller inner diameter is used. Of course, multiple nuts can also be used at the same time.

[0035] The locking portion 31 of the utility model is provided with a tapered hole with the same taper as the tapered surface of the locking portion 31. The inner wall of the tapered hole is preferably provided with a stop tooth 34 for squeezing and locking the grounding wire 5, which is also helpful to increase the friction force and prevent the grounding wire 5 from detaching from the locking portion 31.

[0036] At least one end of the main saddle 1 is integrally molded with an auxiliary saddle 2 through a conductive anti-corrosion metal wire 4. The auxiliary saddle 2 can swing relative to the end of the main saddle 1 through the conductive anti-corrosion metal wire 4. The conductive anti-corrosion metal wire 4 is preferably provided with a plurality of wires to ensure the connection strength between the two. The auxiliary saddle 2 of the utility model is softly connected to the main saddle 1 through the conductive anti-corrosion metal wire 4, and the angle of the auxiliary saddle 2 relative to the end of the main saddle 1 can be adjusted to better adapt to glass fiber reinforced plastic pipes with different outer diameters. For example, auxiliary saddles 2 are connected to both ends of the main saddle 1 (of course, multiple auxiliary saddles 2 can also be provided, and adjacent auxiliary saddles 2 are also connected through the conductive anti-corrosion metal wire 4). When the three saddles are bonded to the glass fiber reinforced plastic pipe, the angle of the two auxiliary saddles 2 relative to the end of the main saddle 1 can be adjusted to better adapt to pipelines with different outer diameters. When the outer diameter of the glass fiber reinforced plastic pipe is larger, the angle can be increased. When the outer diameter of the glass fiber reinforced plastic pipe is smaller, the angle can be decreased or the conductive anti-corrosion metal wire 4 can be cut off, leaving only two saddles or one main saddle 1.

[0037] The side of the main saddle 1 close to the glass fiber reinforced plastic pipe and the side of the auxiliary saddle 2 close to the glass fiber reinforced plastic pipe are both designed as concave arc surfaces, which are convenient for bonding with the outer wall of the glass fiber reinforced plastic pipe.

[0038] The connecting portion of the utility model includes a boss 33 and a clamping portion 32. The boss 33 is connected to the locking portion 31 through the clamping portion 32. The cross-sectional size of the boss 33 is larger than the cross-sectional size of the clamping portion 32. The boss 33 and the part of the clamping portion 32 close to the boss 33 are integrally molded in the main saddle 1. Through this structure, the clamping device 3 can be prevented from detaching from the main saddle 1. The boss 33 is preferably a rectangle or other polygon to prevent the boss 33 from rotating in the main saddle 1.

[0039] The clamping portion 32 is preferably configured as a polygonal column. When the locking nut 6 is rotated, the clamping portion 32 that is not molded into the main saddle 1 is clamped with a tool to facilitate the rotation of the locking nut 6 and prevent the clamping device 3 from rotating with the rotation of the locking nut 6.

[0040] The grounding wire 5 is introduced into the pressing device 3 and extends at least 1 cm, and the end of the grounding wire 5 preferably contacts the clamping portion 32 .

[0041] Specific use steps of this utility model:

[0042] When manufacturing the main saddle 1, the boss 33 of the clamping device 3 and the partial clamping portion 32 close to the boss 33 are integrally molded into the main saddle 1, and then the grounding wire 5 is inserted into the locking portion 31, and then the locking nut 6 is rotated to tighten the locking portion 31, thereby clamping the grounding wire 5 in the clamping device 3.

[0043] By adjusting the angles of the two auxiliary saddles 2, the fiberglass pipes with different outer diameters can be better adapted. When the outer diameter of the fiberglass pipe is larger, the angle can be increased. When the outer diameter of the fiberglass pipe is smaller, the angle can be decreased or the soft connection can be cut off to retain only the main saddle 1 and an auxiliary saddle 2, or only the main saddle 1 can be retained, and then all the saddles are bonded to the fiberglass pipe.

[0044] It should be understood that the purpose of these embodiments is only to illustrate the utility model and is not intended to limit the protection scope of the utility model. In addition, it should also be understood that after reading the technical content of the utility model, those skilled in the art can make various changes, modifications and / or variations to the utility model, and all of these equivalent forms also fall within the protection scope defined by the claims attached to this application.
