[0002] A battery is a device that directly converts chemical energy into electrical energy. It is a rechargeable battery designed to be recharged through a reversible chemical reaction. Usually, it refers to a lead-acid battery. A DC power supply provided by a battery is set in a substation to provide device power and operating power for main equipment such as a substation integrated automation device and a switch device. When the alternating current loses power, the battery quickly provides energy to accident loads, such as various types of emergency lighting, uninterruptible AC power supply, circuit breaker tripping and closing, etc. At the same time, it must also provide power for loads such as control, signal, automatic device, protection device, and communication during accident power outage. The existing battery wiring device has a simple structure, the wiring connection is not tight, and other sealing structures need to be used to seal the connection, resulting in poor sealing effect, easy water seepage, and rainwater entering the wiring, which accelerates the aging of the circuit under the action of current and affects the normal use of the battery.

[0013] Preferably, the bottom of the guide head is connected in series with the on indicator through an inner wire.

[0014] (III) Beneficial effects

[0015] The present invention provides a multi-functional substation battery wiring device, which has the following beneficial effects:

[0016] (1) By providing lifting ears on both sides of the fixed plate, the present invention facilitates the movement and handling of the battery. An on - connection indicator light is provided on the wire - fixing plate. When the sleeve is tightly connected to the guide head and the battery starts to supply power to external power - consuming devices, there is current passing through the on - connection indicator light, which can be used as an indicator of whether the circuit is connected, facilitating the quick location of circuit fault points.

[0017] (2) An opening groove is provided on the sleeve of the present invention. The sleeve and the guide head adopt an interference - fit connection method. When the guide head is inserted into the sleeve, the sleeve wall can elastically deform outward. The restoring force of the sleeve wall presses the guide head, enabling the guide head to be in close contact with the sleeve, avoiding loosening at the connection and preventing circuit short - circuit.

[0018] (3) The present invention provides an outer retaining sleeve that is sleeved on the convex platform of the wiring fixture head in an inverted - buckling form. The connection position between the convex platform and the outer retaining sleeve is at the upper part inside the outer retaining sleeve. Rainwater will not enter the guide head and sleeve inside the convex platform from the outside. A rubber sealing sleeve is provided on the inner wall of the outer retaining sleeve, and the rubber sealing sleeve is connected to the side of the convex platform in an interference - fit form. The rubber sealing sleeve can tightly fill the gap between the convex platform and the outer retaining sleeve, preventing rainwater from seeping into the interior of the outer retaining sleeve. A rotating sleeve is sleeved outside the outer retaining sleeve, and the outer retaining sleeve can be pushed to be sleeved on the convex platform by screwing with the outer side of the wiring fixture head. The installation is convenient and simple. A fixing sleeve is fixed outside the external connecting wire connected to the outer retaining sleeve, preventing excessive stress on the relatively fragile bottom connection of the external connecting wire and causing the bottom of the external connecting wire to break and fall off.

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0025] As Figures 1-4As shown in the figure, the present invention provides a technical solution: a multi-functional substation battery wiring device, including a wire fixing plate 1, a battery body 4, and a wiring fixing head 15. A wire fixing plate 1 is provided on the battery body 4. On the upper end surface of the wire fixing plate 1, lifting ears 5 are symmetrically fixed on both the left and right sides, which is convenient for having a force point for the hand during handling. The height of the lifting ears 5 is higher than that of the wiring fixing head 15 and the swivel sleeve 2 and the fixing sleeve 3 connected to the wiring fixing head 15, which can prevent the wiring terminal from being directly touched when an external object topples. A wiring fixing head 15 is fixed on the wire fixing plate 1 between the lifting ears 5. There are eight wiring fixing heads 15, and the wiring fixing heads 15 in the longitudinal direction of the wire fixing plate 1 are arranged in pairs and evenly distributed on the wire fixing plate 1. An on indicator light 6 is installed outside the position of the wire fixing plate 1 where the wiring fixing head 15 is located. The on indicator light 6 is connected in series with the guide head 13 inside the wiring fixing head 15. When the device is connected and powered on, current passes through the on indicator light 6, and the on indicator light 6 can be powered on and emit light. When there is poor contact at the connection, there is no current passing through the on indicator light 6. The on or off state of the on indicator light 6 can be used to quickly judge the connection situation, which is convenient for timely maintenance and repair. The on indicator light 6 is embedded inside the wire fixing plate 1, and the upper surface of the on indicator light 6 is flush with the surface of the wire fixing plate 1, avoiding the on indicator light 6 being touched when an external sharp object passes over the surface of the wire fixing plate 1, causing damage to the on indicator light 6. Threads 17 are engraved on the outer side wall of the lower part of the wiring fixing head 15. A swivel sleeve 2 is sleeved on the wiring fixing head 15. Threads 17 are engraved at the lower position of the inner side wall of the swivel sleeve 2 corresponding to the threads 17 on the wiring fixing head 15. The threads 17 on the lower part of the inner side wall of the swivel sleeve 2 are in meshing connection with the threads 17 on the outer side wall of the lower part of the wiring fixing head 15. Through the screw-threaded connection, it is convenient for the disassembly of the wiring fixing head 15 and the swivel sleeve 2. A boss 19 is fixed on the upper part of the wiring fixing head 15. The boss 19 is conical. The conical design of the boss 19 is convenient for the outer clamping sleeve 10 inside the swivel sleeve 2 to quickly pass through the smaller upper end of the boss 19 and be clamped on the boss 19. A groove 18 is vertically arranged in the middle of the inner side of the boss 19. A guide head 13 is fixed at the bottom of the groove 18. The guide head 13 is arranged in the groove 18 inside the boss 19, avoiding the direct contact of the guide head 13 with the outside and preventing the guide head 13 from being touched and damaged. The outer shape of the guide head 13 is conical. The conical design of the guide head 13 is convenient for the sleeve 9 to be quickly sleeved on the guide head 13. An outer clamping sleeve 10 is sleeved outside the boss 19. The inner cavity of the outer clamping sleeve 10 is conical. A rubber sealing sleeve 14 is fixed on the inner wall of the outer clamping sleeve 10. The guide head 13 and the inner cavity of the rubber sealing sleeve 14 are in interference fit. When the outer clamping sleeve 10 is sleeved on the guide head 13, the outer wall of the guide head 13 and the inner wall of the outer clamping sleeve 10 jointly squeeze the rubber sealing sleeve 14, making the gap between the guide head 13 and the outer clamping sleeve 10 filled densely. A sleeve 9 is arranged at the top of the inner side of the outer clamping sleeve 10, and the sleeve 9 is fixed on the outer clamping sleeve 10 through a connecting column 8. An opening groove 16 is vertically arranged on the side wall of the sleeve 9. The sleeve 9 is sleeved on the guide head 13, and the inner cavity of the sleeve 9 and the guide head 13 are in interference fit. The design of the opening groove 16 on the side wall of the sleeve 9 makes it possible that when the sleeve 9 is interference-fitted on the guide head 13,The side wall of the sleeve 9 undergoes elastic deformation under the action of the extrusion force. The side wall of the sleeve 9 will apply a certain force to hold the guide head 13, making the connection between the sleeve 9 and the guide head 13 tight. The lower part of the sleeve 9 is arranged in the groove 18, and there is a clearance fit between the outer side of the sleeve 9 and the groove 18. The outer clamping sleeve 10 is arranged inside the rotating sleeve 2, and there is a clearance fit between the rotating sleeve 2 and the outer clamping sleeve 10. The upper part of the outer clamping sleeve 10 is connected with a fixing sleeve 3. An external connecting wire 7 is sleeved inside the fixing sleeve 3, and the lower end of the external connecting wire 7 is connected to the upper end of the terminal post. There is an interference fit between the external connecting wire 7 and the fixing sleeve 3. The fixing sleeve 3 is fixed outside the external connecting wire 7 connected to the outer clamping sleeve 10, avoiding excessive force on the relatively fragile bottom connection of the external connecting wire 7, resulting in the fracture and detachment of the bottom of the external connecting wire 7. There is a clearance fit between the upper hole ring of the rotating sleeve 2 and the fixing sleeve 3. A rubber sealing ring 12 is fixed at the bottom of the rotating sleeve 2. When the rotating sleeve 2 is rotated downward to connect with the terminal fixing head 15, the bottom of the rotating sleeve 2 presses the rubber sealing ring 12, making the bottom of the rubber sealing ring 12 closely fit with the wire fixing plate 1, preventing rainwater from entering the rotating sleeve 2. The bottom of the guide head 13 is connected in series with the on - indicator light 6 through the internal wire 11.,

[0026] During use, connect the external connecting wire 7 to the external power supply terminal. Hold the rotating sleeve 2 and sleeved the rotating sleeve 2 on the corresponding terminal fixing head 15 on the wire fixing plate 1. Rotate the rotating sleeve 2. The rotating sleeve 2 and the terminal fixing head 15 are screwed together through the thread 17. During the screwing process of the rotating sleeve 2, the rubber sealing ring 12 at the bottom of the rotating sleeve 2 moves towards the wire fixing plate 1 and gradually contacts the wire fixing plate 1. The bottom of the rotating sleeve 2 presses the rubber sealing ring 12, making the bottom of the rubber sealing ring 12 closely fit with the wire fixing plate 1, preventing rainwater from entering the rotating sleeve 2. During this process, the outer clamping sleeve 10 inside the rotating sleeve 2 is directly sleeved on the boss 19. The conical design of the boss 19 facilitates the outer clamping sleeve 10 inside the rotating sleeve 2 to quickly pass through the smaller upper end of the boss 19 and be clamped on the boss 19. When the outer clamping sleeve 10 is sleeved on the guide head 13, the outer wall of the guide head 13 and the inner wall of the outer clamping sleeve 10 jointly press the rubber sealing sleeve 14, making the gap between the guide head 13 and the outer clamping sleeve 10 filled densely. At this time, the sleeve 9 is sleeved on the guide head 13. The conical design of the guide head 13 facilitates the sleeve 9 to be quickly sleeved on the guide head 13. The design of the opening groove 16 on the side wall of the sleeve 9 enables the side wall of the sleeve 9 to undergo elastic deformation under the action of the extrusion force when the sleeve 9 is interference - sleeved on the guide head 13. The side wall of the sleeve 9 will apply a certain force to hold the guide head 13, making the connection between the sleeve 9 and the guide head 13 tight. The contact area between the sleeve 9 and the guide head 13 is large, preventing a small contact area, resulting in a large resistance at the contact point. When current passes through, the contact point generates a large amount of heat, causing the circuit to burn out and break. The fixing sleeve 3 is fixed outside the external connecting wire 7, avoiding excessive force on the relatively fragile bottom connection of the external connecting wire 7, resulting in the fracture and detachment of the bottom of the external connecting wire 7.,

[0027] In summary, the present invention solves the problems of poor waterproof performance at the battery connection part of the multi-functional substation and the inability to obtain timely feedback on the line connection information by providing the wire fixing plate 1, the battery body 4 and the wiring fixing head 15.
