Description

Technical Field

[0001] This utility model belongs to the field of hydropower technology, specifically relating to a sealing and locking device for hydropower generation. Background Technology

[0002] Distribution boxes are divided into power distribution boxes, lighting distribution boxes, and metering boxes, and are the final-level equipment in a power distribution system. Distribution boxes are a general term for motor control centers. Distribution boxes are used in situations where the load is relatively dispersed and there are fewer circuits; motor control centers are used in situations where the load is concentrated and there are more circuits. They distribute the electrical energy from a circuit of the upstream power distribution equipment to the nearest load. This level of equipment should provide protection, monitoring, and control for the load. Hydropower stations, as core facilities for clean energy, have distribution boxes that undertake key functions such as power distribution, equipment protection, and intelligent control.

[0003] Traditionally, when installing incoming and outgoing lines in a distribution cabinet, several incoming and outgoing lines are bundled together and passed through a hole on the surface of the distribution cabinet. This method is not conducive to the maintenance of the wiring harness later, as the wire harnesses become tangled and interfere with each other. At the same time, this method cannot guarantee the sealing performance required for distribution cabinets used in hydropower stations. Therefore, we have proposed a sealing and locking device for hydropower generation. Utility Model Content

During line installation, the plug-in block and sealing gasket on the surface of the mounting plate are inserted into the mounting groove and fixed with fixing bolts. The line is placed in the circular groove on the surface of the mounting plate and the plug-in block. At this time, the line is in the wiring hole on the surface of the fixing block. Pulling the lever moves the slider, causing the plug rod to move from the slot into the groove. The plug plate on the mounting block is inserted into the slot. The surface of the plug plate first contacts the abutment block. As the plug plate moves, the abutment block deforms. When the surface of the mounting block contacts the surface of the fixing block, the locking groove aligns with the plug rod. The lever is released, and the slider is pushed by the spring to move, so that the plug rod is inserted into the locking groove, thereby fixing the mounting block to the surface of the fixing block. This separates multiple sets of lines, preventing the wire harnesses from getting tangled and affecting subsequent maintenance.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-5 One embodiment provided by this utility model: A sealing and locking device for hydroelectric power generation includes a distribution box 1, with electrical equipment 11 installed inside. A stop block 12 is fixedly connected to the front of the distribution box 1, and a sealing ring 13 is fixedly connected to the surface of the stop block 12. A mounting groove 14 is provided on one side of the distribution box 1. A door 2 is hinged to the front of the distribution box 1. A wire harness structure 3 is provided on one side of the distribution box 1. The wire harness structure 3 includes a mounting plate 31. Fixing bolts 32 are rotatably connected to the four corners of the mounting plate 31. A plug-in block 33 is fixedly connected to one end of the mounting plate 31, and a sealing gasket 34 is sleeved on the outside of the plug-in block 33. A fixing block 35 is fixedly connected to the other end of the mounting plate 31. Two sets of slots 36 are provided on the surface of the fixing block 35, and a mounting block 37 is installed on the surface of the fixing block 35. Multiple sets of wiring holes 38 are formed on the surfaces of mounting block 37 and slot 36. A sealing ring 39 is fixedly connected inside each wiring hole 38. Two sets of insert plates 310 are fixedly connected to the surface of mounting block 37. A slot 311 is formed on the surface of insert plate 310. A locking structure 4 is provided inside the fixing block 35. The locking structure 4 includes a sliding groove 41. A slider 42 is slidably connected inside the sliding groove 41. A lever 43 is fixedly connected to the side of slider 42. A rod 44 is fixedly connected to the surface of slider 42. A spring 45 is fixedly connected to the surface of slider 42. A stop block 46 is fixedly connected to the inner wall of slot 36. A circular groove that mates with the wiring holes 38 is formed on the surfaces of mounting plate 31 and insert block 33. A wire harness structure 3 and a locking structure 4 are provided for wiring installation. During installation, insert the connector 33 and sealing gasket 34 on the surface of the mounting plate 31 into the mounting groove 14 and fix them with fixing bolts 32. Place the wire in the circular groove on the surface of the mounting plate 31 and connector 33. At this time, the wire is in the wiring hole 38 on the surface of the fixing block 35. Pull the lever 43 to move the slider 42, so that the connector 44 moves from the slot 36 into the slide groove 41. Insert the connector 310 on the mounting block 37 into the slot 36. The surface of the connector 310 first contacts the abutment block 46. As the connector 310 moves, the abutment block 46 deforms. When the surface of the mounting block 37 contacts the surface of the fixing block 35, the slot 311 aligns with the connector 44. Release the lever 43, and the slider 42 is pushed to move under the action of the spring 45. The insertion rod 44 is inserted into the slot 311, thereby fixing the mounting block 37 to the surface of the fixing block 35. This separates multiple sets of wires, preventing them from tangling and affecting subsequent maintenance. A sealing ring 13, a sealing gasket 34, and a sealing ring 39 are provided. When the box door 2 is closed, the inner surface of the box door 2 contacts the sealing ring 13 and cooperates with the stop block 12 to compress the sealing ring 13, increasing the sealing performance at the box door 2. When installing the wire harness structure 3, the sealing gasket 34 increases the tightness of the insertion block 33 in the mounting groove 14, ensuring sealing performance. The sealing ring 39 seals the wiring hole 38 by abutting against the wire surface, increasing the overall sealing performance of the distribution box 1 and ensuring that the distribution box 1 meets the sealing requirements for use in hydropower stations.

[0018] Furthermore, the stop 12 is C-shaped, the sealing ring 13 is made of rubber, and the surface of the door 2 abuts against the sealing ring 13. When the door 2 is closed, the inner surface of the door 2 contacts the sealing ring 13 and cooperates with the stop 12 to compress the sealing ring 13, thereby increasing the sealing performance of the door 2.

[0019] Furthermore, the plug-in block 33 and the sealing gasket 34 are inserted into the mounting groove 14. The mounting groove 14 and the mounting plate 31 have threaded grooves at their four corners. The fixing bolts 32 are rotatably connected in the threaded grooves. The plug-in block 33 and the sealing gasket 34 on the surface of the mounting plate 31 are inserted into the mounting groove 14 and fixed by the fixing bolts 32. The sealing gasket 34 increases the tightness of the plug-in block 33 in the mounting groove 14.

[0020] Furthermore, the two sets of insert plates 310 are respectively inserted into the two sets of slots 36. The surface of the insert plate 310 abuts against the surface of the abutment block 46. The insert plate 310 on the mounting block 37 is inserted into the slot 36. The surface of the insert plate 310 first contacts the abutment block 46. As the insert plate 310 moves, the abutment block 46 deforms. Then, the insert plate 310 is fixed by the locking structure 4. At this time, the abutment block 46 has a tendency to return to its original shape, which makes the insert plate 310 have a tendency to move outward, increasing the tightness of the connection between the insert plate 310, the slot 36 and the locking structure 4.

[0021] Furthermore, the slot 36 and the slide 41 are interconnected. The radius of the slot 311 is equal to the radius of the insert rod 44. When the surface of the mounting block 37 contacts the surface of the fixing block 35, the slot 311 and the insert rod 44 are aligned, and the insert rod 44 is inserted into the slot 311, thereby fixing the mounting block 37 to the surface of the fixing block 35.

[0022] Furthermore, the two ends of the spring 45 are fixedly connected to the inner wall of the slide groove 41 and the surface of the slider 42, respectively. When there is no external force, the spring 45 pushes the slider 42 to move, so that the dial plate 43 abuts against the inner wall of the slide groove 41 on the side away from the spring 45. At this time, the insertion rod 44 is slidably connected in the slot 36.

[0023] Furthermore, the sealing gasket 34, the second sealing ring 39, and the abutment block 46 are all made of rubber. The sealing gasket 34 and the second sealing ring 39 seal the mounting groove 14 and the wiring hole 38, respectively. The abutment block 46 increases the tightness of the connection between the insert plate 310, the slot 36, and the locking structure 4.

[0024] Working principle: When the door 2 is closed, the inner surface of the door 2 contacts the sealing ring 13 and cooperates with the stop block 12 to compress the sealing ring 13, increasing the sealing performance of the door 2. During wiring installation, the plug-in block 33 and the sealing gasket 34 on the surface of the mounting plate 31 are inserted into the mounting groove 14 and fixed with the fixing bolt 32. The sealing gasket 34 increases the tightness of the plug-in block 33 in the mounting groove 14. The wire is placed in the circular groove on the surface of the mounting plate 31 and the plug-in block 33. At this time, the wire is in the wiring hole 38 on the surface of the fixing block 35. Pulling the lever 43 moves the slider 42, causing the plug rod 44 to move from the slot 3. The mounting block 37 is moved into the groove 41, and the insert plate 310 on the mounting block 37 is inserted into the slot 36. The surface of the insert plate 310 first contacts the abutment block 46. As the insert plate 310 moves, the abutment block 46 deforms. When the surface of the mounting block 37 contacts the surface of the fixing block 35, the slot 311 aligns with the insert rod 44. The lever 43 is released, and the slider 42 is pushed to move under the action of the spring 45, so that the insert rod 44 is inserted into the slot 311, thereby fixing the mounting block 37 to the surface of the fixing block 35, thereby separating and bundling multiple sets of lines. The sealing ring 39 seals the wiring hole 38 by abutting against the surface of the line.
