Description

Technical Field

[0001] The utility model relates to the technical field of photoelectric signal transceivers, in particular to a photoelectric signal transceiver for a hydropower plant. Background Art

[0002] A transceiver is a device for signal conversion, usually a fiber optic transceiver. The emergence of fiber optic transceivers converts twisted pair electrical signals and optical signals to each other, ensuring smooth transmission of data packets between two networks. For example, the patent document with application number CN202021696907.3 discloses an optoelectronic signal transceiver that is easy to maintain. By pulling the turntable, the turntable drives the limit rod to move out of the limit block through the top plate. The operation is simple, which reduces the work intensity of the staff and facilitates the staff to repair the optoelectronic signal transceiver.

[0003] However, in the above-mentioned similar schemes, since several groups of wires need to be inserted at both ends of the signal transceiver, when the wire interface and the wire are not on the same horizontal line, the wire will be bent at the connection when it is plugged in, thereby damaging the wire. In addition, due to the humid air in the hydropower plant, water will enter the inside of the transceiver, causing an internal short circuit, thereby reducing the life of the transceiver.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a hydropower plant optoelectronic signal transceiver is proposed. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a hydropower plant photoelectric signal transceiver, which solves the above-mentioned similar solutions proposed in the above-mentioned background technology. Since several groups of wires need to be inserted at both ends of the signal transceiver, when the wire interface and the wire are not on the same horizontal line, the wires are bent at the connection when they are plugged in, thereby damaging the wires. In addition, due to the humid air in the hydropower plant, water enters the inside of the transceiver, causing an internal short circuit, thereby reducing the life of the transceiver.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a hydropower plant optoelectronic signal transceiver, comprising a lower fixed shell, a sealing assembly and an anti-breaking assembly, the upper end of the lower fixed shell is plugged with an upper fixed shell, and the sealing assembly is located below the upper fixed shell, and the sealing assembly comprises threaded holes, limiting protrusions, limiting grooves and sealing rings, four groups of threaded holes are fixed at the upper end edge of the lower fixed shell, and the upper end surface of the lower fixed shell is fixed with the limiting grooves, and the sealing ring is embedded above the limiting grooves, the lower end surface of the upper fixed shell is fixed with the limiting protrusions, and the anti-breaking assembly is located at the front end surface of the lower fixed shell, and the anti-breaking assembly comprises a roller bearing, a support plate, a rotating rod and a corrugated tube, the front end surface of the lower fixed shell is penetrated by the roller bearing, and the inner side of the roller bearing is hinged with the supporting plate, and the two ends of the supporting plate are hinged with the rotating rods, and the front end surface of the support plate is threadedly connected with the corrugated tube.

[0007] Furthermore, the structure of the limiting protrusion is adapted to the structure of the limiting groove, and the lower fixing shell forms a disassembly structure with the upper fixing shell through screws.

[0008] Furthermore, a through hole is penetrated through the front end surface of the lower fixed shell, and a threaded opening is fixed at the front end of the through hole.

[0009] Furthermore, the roller bearing is located on the inner side of the through hole, and a socket is fixed on the inner side of the support plate.

[0010] Furthermore, the socket forms a rotating structure through the support plate and the rotating rod, and a threaded interface is fixed to the right end of the corrugated tube.

[0011] Furthermore, the corrugated tube forms a disassembly structure with the lower fixed shell through the threaded interface and the threaded port, and the upper fixed shell forms a sealing structure with the lower fixed shell through a sealing ring.

[0012] The utility model provides a hydropower plant photoelectric signal transceiver, which has the following beneficial effects:

[0013] It can prevent the wire from bending at the connection when the wire interface and the wire are not on the same horizontal line, thereby avoiding damage to the wire and protecting the wire. In addition, it can prevent water from entering the transceiver when the signal transceiver is in a wet state, preventing internal short circuit, and improving the life of the transceiver. The specific contents are as follows:

[0014] First, place the sealing ring in the limit groove, and insert the limit protrusion into the limit groove, so that a sealing structure is formed on the inside of the signal transceiver, and then insert the wire into the socket. At the same time, because the wire and the transceiver are not on the same horizontal line, the support plate is driven to rotate along the rotating rod, and at the same time, the support plate drives the roller bearing to rotate, so that the wire interface and the socket are connected in a straight line, thereby avoiding breakage at the wire interface.

DETAILED DESCRIPTION

[0020] The following is a further detailed description of the implementation of the present utility model in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0021] like Figures 1 to 4As shown, the optoelectronic signal transceiver of the hydropower plant includes a lower fixed shell 1, a sealing component 3 and an anti-breakage component 5. The upper end of the lower fixed shell 1 is plugged with the upper fixed shell 2 to avoid the inconvenience of repairing the internal components due to the integrated structure. The sealing component 3 is located below the upper fixed shell 2, and the sealing component 3 includes a threaded hole 301, a limiting protrusion 302, a limiting groove 303 and a sealing ring 304. Four groups of threaded holes 301 are fixed at the upper edge of the lower fixed shell 1, the lower end surface of the upper fixed shell 2 is fixed with a limiting protrusion 302, and the upper end surface of the lower fixed shell 1 is fixed with a limiting groove 303. The structure of the limiting protrusion 302 is adapted to the structure of the limiting groove 303, so that The side of the limiting protrusion 302 fits with the side of the limiting groove 303, which is beneficial to improving the sealing of the connection. The lower fixed shell 1 and the upper fixed shell 2 form a disassembly structure through screws, abandoning the elastic clamping connection method, which can improve the firmness of the connection. A sealing ring 304 is embedded above the limiting groove 303, and the sealing ring 304 is embedded in the inner side of the limiting groove 303, so that the upper fixed shell 2 and the lower fixed shell 1 form a sealing structure through the sealing ring 304, which can improve the sealing of the connection. When the signal transceiver is in a wet state, water can be prevented from entering the transceiver and internal short circuit can be prevented, which is beneficial to improving the life of the transceiver.

[0022] The anti-breaking component 5 is located at the front end surface of the lower fixed shell 1, and the anti-breaking component 5 includes a roller bearing 501, a support plate 502, a rotating rod 503 and a corrugated tube 504. The front end surface of the lower fixed shell 1 is penetrated with a through hole 4 for supporting the roller bearing 501. The front end surface of the lower fixed shell 1 is penetrated with a roller bearing 501, and the inner side of the roller bearing 501 is hinged with a support plate 502 for protecting the socket 521 and forming a connection support for the roller bearing 501 and the socket 521. The roller bearing 501 is located on the inner side of the through hole 4, and the inner side of the support plate 502 is fixed with a socket 521. The socket 521 is fixed by the support plate 502, thereby improving the stability of the socket 521 and improving the firmness of the connection between the wire and the socket 521. The rotating rods 503 are hinged at both ends of the support plate 502, and the socket 521 forms a rotating The structure can expand the range of the upward and downward movement of the socket 521, and the support plate 502 can be rotated by the roller bearing 501 to change the direction of the socket 521, so that when the wire interface and the wire are not on the same horizontal line, the wire can be prevented from bending at the connection point, thereby avoiding damage to the wire, which is beneficial to protecting the wire. The front end surface of the support plate 502 is threadedly connected with a corrugated tube 504, and the left end of the corrugated tube 504 is tapered and fits with the wire, thereby improving the sealing between the wire and the socket 521, which is used to further improve the sealing of the device, and the right end of the corrugated tube 504 is fixed with a threaded interface 541, and the front end of the through hole 4 is fixed with a threaded opening 6. The corrugated tube 504 forms a disassembly structure with the lower fixed shell 1 through the threaded interface 541 and the threaded opening 6, which is convenient for quick disassembly and installation of the corrugated tube 504, and convenient for quick insertion of the wire into the socket 521, preventing the corrugated tube 504 from blocking the line of sight.

[0023] In summary, when this type of hydropower plant optoelectronic signal transceiver is used, first, the sealing ring 304 is placed on the inner side of the limiting groove 303, and then the upper fixed shell 2 is buckled on the upper end of the lower fixed shell 1. At this time, the limiting protrusion 302 is inserted into the inner side of the limiting groove 303, and the lower end of the limiting protrusion 302 is in contact with the sealing ring 304. At this time, a sealing structure is formed on the inner side of the device, and then the wire is inserted into the socket 521, and the threaded interface 541 at the right end of the corrugated tube 504 is tightened on the outer side of the threaded port 6. When the wire and the transceiver are not on the same horizontal line, the support plate 502 first rotates with the roller bearing 501, and at the same time, the support plate 502 rotates along the rotating rod 503, so that the wire and the socket 521 are connected in a straight line, thereby avoiding breakage at the wire interface.
