Description
Technical Field
[0001] This utility model belongs to the field of leakage current safety protection technology, specifically a generator manifold grounding device. Background Technology
[0002] As a core component of the stator winding water cooling system, the generator water manifold is responsible for the collection and distribution of cooling water.
[0003] The stator winding bars are cooled by water circulation, with each bar forming an independent water circuit. The inlet and outlet water manifolds are located at both ends of the winding and connected to the bars via insulated water pipes, forming a closed-loop cooling circuit to ensure that the heat generated during generator operation is carried away in a timely manner. The flange between the water manifold and the external water pipe is insulated. If the insulation at the winding end is damaged or the insulated water pipe breaks down, the water manifold may become energized. Therefore, the generator water manifold needs to be grounded using a conductor. Existing grounding devices mostly use bolts to connect the conductor and the grounding conductive part, or use welding to connect them. Welding is inconvenient for replacing the conductor, while bolted connections require tools for disassembly and maintenance, which is inconvenient.
[0004] Therefore, this utility model provides a generator manifold grounding device. Utility Model Content
[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.
[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The generator water pipe grounding device of this utility model includes a bracket, a grounding guide plate is provided inside the bracket, a pressure plate is slidably connected to the middle of the bracket, an adjusting plate is rotatably connected to the middle of the bracket, a top rod is fixed to the side wall of the adjusting plate, a connecting groove is fixed to the middle of the adjusting plate, and a limit block is slidably connected to the middle of the bracket. With the above structure, the grounding wire and the grounding guide plate can be connected, fixed and separated in a relatively convenient way, which is more convenient to use than the traditional bolt fixing method.
[0007] Preferably, a slide rail is fixed to the side wall of the bracket, a lower protective sleeve is provided on the ground outside the bracket, an upper protective sleeve is installed on the outside of the bracket, and a connector is fixed to the inner side wall of the upper protective sleeve. The connector is slidably and rotatably connected to the inside of the slide rail. With the above structure, the grounding device can be easily protected after the grounding wire is connected, reducing the safety hazards caused by accidental contact and collision with external objects.
[0008] Preferably, a movable seat is slidably connected to the middle of the top rod, and an adjusting bolt is rotatably connected to the middle of the movable seat. The adjusting bolt is threadedly connected to the middle of the adjusting plate, and a top wheel is installed in the middle of the movable seat. With the above structure, the device can be easily adjusted according to the different widths of the wires, so that wires of different widths can be pressed tightly on the grounding guide plate, thereby improving the applicability of the device.
[0009] Preferably, the top wheel is rotatably connected to the middle of the movable seat, and the surface of the top wheel is made of rubber. Through the above structure, the sliding friction between some components can be transformed into rolling friction, reducing the wear of the components and increasing their service life.
[0010] Preferably, a pull rope is fixed to the side wall of the pressure plate, and the other end of the pull rope is fixed to the middle of the movable seat. With the above structure, when it is necessary to insert the grounding wire between the grounding guide plate and the pressure plate, sufficient operating space is ensured between the grounding guide plate and the pressure plate, thus improving the convenience of operation.
[0011] Preferably, a limiting rod is fixedly connected to the side wall of the bracket, and the limiting rod and the slide rail are arranged in parallel. A fixing strip is fixedly connected to the inner side wall of the upper protective sleeve. Through the above structure, the upper protective sleeve is difficult to rotate and contact with the internal components, thereby reducing the occurrence of the upper protective sleeve rotating and impacting the internal components when the upper protective sleeve is subjected to external collision, and improving the protective effect.
[0012] Preferably, the top of the channel formed by the limiting rod and the slide rail is flared. With the above structure, the operation can be guided by the flared opening when the upper protective sleeve is lowered and the fixing strip is inserted into the channel between the limiting rod and the slide rail, thereby improving the convenience of operation.
[0013] The beneficial effects of this utility model are as follows: 1. The generator manifold grounding device of this utility model, through the setting of bracket, grounding guide plate, pressure plate, adjusting plate, top rod, connecting groove and limiting block, can conveniently connect, fix and separate the grounding wire and grounding guide plate, which is more convenient to use than the traditional bolt fixing method.
[0014] 2. The generator manifold grounding device of this utility model, through the setting of slide rail, lower protective sleeve, upper protective sleeve and connector, can conveniently protect the grounding device after the grounding wire is connected, reducing the safety hazards caused by accidental contact and collision with external objects.

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0019] like Figures 1 to 4 As shown in the figure, a generator manifold grounding device according to an embodiment of the present invention includes a bracket 1. A grounding guide plate 12 is provided inside the bracket 1. A pressure plate 13 is slidably connected to the middle of the bracket 1. An adjusting plate 14 is rotatably connected to the middle of the bracket 1. A top rod 15 is fixedly connected to the side wall of the adjusting plate 14. A connecting groove 16 is fixedly connected to the middle of the adjusting plate 14. A limit block 17 is slidably connected to the middle of the bracket 1. During operation, the exposed end of the grounding wire of the manifold to be connected is placed between the grounding guide plate 12 and the pressure plate 13. Then, the adjusting plate 14 is rotated. During the rotation of the adjusting plate 14, the end of the top rod 15 contacts and abuts against the pressure plate 13, causing the pressure plate 13 to face towards the grounding guide plate 12. As the adjusting plate 14 rotates continuously, the pressure plate 13 presses the end of the grounding wire tightly against the grounding conductor plate 12. After the adjusting plate 14 is rotated into place, the sliding limit block 17 causes its center to sink into the connecting groove 16, thereby completing the connection and fixation of the grounding wire and the grounding conductor plate 12. This allows the current to be conducted through the wire to the grounding conductor plate 12 and then to the ground. When the grounding wire is damaged, the above operation can be reversed to remove the wire end so that the grounding wire of the water pipe can be replaced. With the above structure, the grounding wire and the grounding conductor plate 12 can be connected, fixed, and disassembled more conveniently than the traditional bolt fixing method.
[0020] like Figures 1 to 5As shown, a slide rail 2 is fixed to the side wall of the bracket 1. A lower protective sleeve 21 is provided on the ground outside the bracket 1. An upper protective sleeve 22 is installed on the outside of the bracket 1. A connector 23 is fixed to the inner side wall of the upper protective sleeve 22. The connector 23 is slidably and rotatably connected to the inside of the slide rail 2. During operation, when it is necessary to connect or disconnect the wire, the upper protective sleeve 22 is slid up. After the connector 23 slides to the top of the slide rail 2, the upper protective sleeve 22 is rotated to fully expose the connection between the adjusting plate 14 and the grounding guide plate 12 and the wire for operation. After the operation is completed, the upper protective sleeve 22 is rotated to the top of the bracket 1, and then the upper protective sleeve 22 is slid down so that the upper protective sleeve 22 falls on the lower protective sleeve 21. Thus, the combination of the upper protective sleeve 22 and the lower protective sleeve 21 can protect and isolate the interior. With the above structure, after the grounding wire is connected, the grounding device can be easily protected, reducing the safety hazards caused by accidental contact and collision with external objects.
[0021] like Figures 1 to 4 As shown, a movable seat 3 is slidably connected to the middle of the top rod 15, and an adjusting bolt 31 is rotatably connected to the middle of the movable seat 3. The adjusting bolt 31 is threadedly connected to the middle of the adjusting plate 14, and a top wheel 32 is installed in the middle of the movable seat 3. Since the wires connecting the grounding guide plate 12 and the generator water pipe are of different thicknesses and have different cross-sections (some circular and some flat), the distance between the grounding guide plate 12 and the pressure plate 13 is also different when the wires are pressed. Therefore, when connecting different wires, the adjusting bolt 31 can be rotated to move the movable seat 3, and the distance between the top wheel 32 and the adjusting plate 14 can be adjusted. After the adjusting plate 14 is rotated to the corresponding position, the top wheel 32 pushes the pressure plate 13 to the corresponding position and presses the wire tightly onto the grounding guide plate 12. With the above structure, the device can be easily adjusted according to the different widths of the wires, so that wires of different widths can be pressed tightly onto the grounding guide plate 12, improving the applicability of the device.
[0022] like Figures 1 to 4 As shown, the top wheel 32 is rotatably connected to the middle of the movable seat 3. The surface of the top wheel 32 is made of rubber. When the adjusting plate 14 is rotated, the top wheel 32 will first contact the pressure plate 13. As the adjusting plate 14 continues to rotate, the top wheel 32 will roll along the surface of the pressure plate 13. Through the above structure, the sliding friction between some components can be transformed into rolling friction, reducing the wear of components and improving the service life of components.
[0023] like Figures 1 to 4As shown, a pull rope 5 is fixed to the side wall of the pressure plate 13. The other end of the pull rope 5 is fixed to the middle of the movable seat 3. When it is necessary to disconnect the grounding wire from the grounding guide plate 12, the adjusting plate 14 needs to be rotated to move the top wheel 32 to release the pressure on the pressure plate 13. At this time, the movable seat 3 and the top wheel 32 will move away from the pressure plate 13, and the pull rope 5 will gradually tighten and pull the pressure plate 13 to move away from the grounding guide plate 12. Thus, after the grounding wire is removed from between the grounding guide plate 12 and the pressure plate 13, there is enough space between the grounding guide plate 12 and the pressure plate 13 so that the grounding wire can be inserted between the grounding guide plate 12 and the pressure plate 13 again. Through the above structure, when it is necessary to insert the grounding wire between the grounding guide plate 12 and the pressure plate 13, it is ensured that there is enough operating space between the grounding guide plate 12 and the pressure plate 13, which improves the convenience of operation.
[0024] like Figures 1 to 5 As shown, a limiting rod 6 is fixedly connected to the side wall of the bracket 1. The limiting rod 6 and the slide rail 2 are arranged in parallel. A fixing strip 61 is fixedly connected to the inner side wall of the upper protective sleeve 22. When using the upper protective sleeve 22 for protection, the fixing strip 61 is inserted into the channel between the limiting rod 6 and the slide rail 2, making it difficult for the upper protective sleeve 22 to rotate and contact the internal components. This reduces the occurrence of the upper protective sleeve 22 rotating and hitting the internal components when it is subjected to external impact, thus improving the protective effect.
[0025] like Figure 2 As shown, the top of the channel formed by the limiting rod 6 and the slide rail 2 is flared. With the above structure, the operation can be guided by the flared opening when the upper protective sleeve 22 is lowered and the fixing strip 61 is inserted into the channel between the limiting rod 6 and the slide rail 2, thereby improving the convenience of operation.
[0026] During operation, the exposed end of the grounding conductor of the water pipe to be connected is placed between the grounding conductor plate 12 and the pressure plate 13. Then, the adjusting plate 14 is rotated. During the rotation of the adjusting plate 14, the end of the push rod 15 will contact and press against the pressure plate 13, causing the pressure plate 13 to move towards the grounding conductor plate 12. As the adjusting plate 14 continues to rotate, the pressure plate 13 will tightly press the end of the grounding conductor onto the grounding conductor plate 12. After the adjusting plate 14 is rotated into place, the sliding limit block 17 will cause the middle part of the limit block 17 to sink into the connecting groove 16, thereby completing the connection and fixation of the grounding conductor and the grounding conductor plate 12, allowing the current to be conducted through the conductor to the grounding conductor plate 12 and then into the ground. When the grounding conductor is subjected to When damaged, the above operation can be reversed to remove the wire end so that the grounding wire of the water collection pipe can be replaced. When it is necessary to connect or disconnect the wire, slide the upper protective sleeve 22 upward. After the connector 23 slides to the top of the slide rail 2, rotate the upper protective sleeve 22 to fully expose the connection between the adjusting plate 14 and the grounding guide plate 12 and the wire for operation. After the operation is completed, rotate the upper protective sleeve 22 to the top of the bracket 1, and then slide the upper protective sleeve 22 down so that the upper protective sleeve 22 falls on the lower protective sleeve 21. Thus, the combination of the upper protective sleeve 22 and the lower protective sleeve 21 can protect and isolate the interior. Since the wires connecting the grounding guide plate 12 and the generator water collection pipe are of different thicknesses and some have circular cross-sections, The cross-section of the grounding conductor is flat, so the distance between the grounding plate 12 and the pressure plate 13 varies when the conductor is pressed. Therefore, when connecting different conductors, the adjusting bolt 31 can be rotated to move the movable seat 3, adjusting the distance between the top wheel 32 and the adjusting plate 14. After the adjusting plate 14 rotates to the corresponding position, the top wheel 32 pushes the pressure plate 13 to the corresponding position and presses the conductor tightly onto the grounding conductor 12. When the adjusting plate 14 is rotated, the top wheel 32 will first contact the pressure plate 13. As the adjusting plate 14 continues to rotate, the top wheel 32 will roll along the surface of the pressure plate 13. When it is necessary to disconnect the grounding conductor from the grounding plate 12, the adjusting plate 14 needs to be rotated to move the top wheel 32 to release the pressure. When the plate 13 is pressed, the movable seat 3 and the top wheel 32 will move away from the pressure plate 13. The pull rope 5 will gradually tighten and pull the pressure plate 13 to move away from the grounding guide plate 12. This will leave enough space between the grounding guide plate 12 and the pressure plate 13 after the grounding wire is removed from between the grounding guide plate 12 and the pressure plate 13 so that the grounding wire can be inserted between the grounding guide plate 12 and the pressure plate 13 again. When using the upper protective sleeve 22 for protection, the fixing strip 61 is inserted into the channel between the limit rod 6 and the slide rail 2, making it difficult for the upper protective sleeve 22 to rotate and contact the internal components. This will reduce the occurrence of the upper protective sleeve 22 rotating and hitting the internal components when it is subjected to external impact.
