Description

Technical Field

[0001] The invention relates to the field of outdoor isolating switches, and in particular to a pressure-welded soft connection structure of an outdoor isolating switch. Background Art

[0002] In the installation and use of outdoor disconnectors, it is usually necessary to connect and install parts through pressure welding soft connections to ensure circuit flow and achieve buffer protection. Pressure welding soft connection equipment is an important equipment widely used in various industries. Its principle is to use thermoplastic deformation under high pressure to make the surface of metal materials produce plastic flow, thereby forming a solid connection. Pressure welding soft connection has a fast and efficient connection speed, and can achieve multiple connection tasks in a short time, greatly improving production efficiency. At the same time, since the pressure welding soft connection equipment uses pure mechanical pressure for connection, no chemical substances or current are required, which avoids environmental pollution and electromagnetic radiation problems. After long-term use, the pressure welding soft connection structure of the outdoor disconnector may cause depression in the abutment area between adjacent structures. To ensure safe operation, the staff needs to perform depression detection on the area before closing the switch. However, due to the physical characteristics of the abutment area, it is difficult to observe, which affects the efficiency of the pressure welding soft connection structure detection work. Summary of the invention

[0003] The purpose of the present invention is to solve the problems in the background technology and to propose a pressure welding soft connection structure of an outdoor disconnector.

[0004] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a pressure-welded soft connection structure of an outdoor disconnector, comprising a bottom plate, two symmetrical soft connection bodies are arranged on the top of the bottom plate, two symmetrical limit plates are arranged on the side away from each other of the two soft connection bodies, two symmetrical mounting frames are fixedly connected between the two limit plates by screws, electric telescopic rods are fixedly installed on the side walls of the two mounting frames, a scraper plate is fixedly installed between the telescopic ends of the two electric telescopic rods, square frames are welded on the upper and lower ends of the scraper plate, two mounting plates are welded on the side walls of the inner cavity of the scraper plate, a plurality of sleeves are fixedly installed on the side away from each other of the two mounting plates, and each of the sleeves The inner cavity is slidably provided with a sliding rod, the bottom of each sleeve inner cavity is connected to a spring 1, and each spring is connected one by one between the bottom of each sleeve inner cavity and the bottom of the sliding rod, a collecting pipe is connected between the bottoms of several sleeves, a water tank is fixedly installed on the side wall of the scraper plate, and the collecting pipe is connected to the water tank on the side outside the scraper plate, a spring 2 is connected to the top of the water tank inner cavity, and a piston plate is connected to the bottom of the spring 2, and the two electric telescopic rods drive the scraper plate to move in the direction where the two soft connection bodies abut against each other, and the scraper plate will scrape off the oxide in the abutting area of ​​the two soft connection bodies during the movement, thereby improving the working efficiency of the soft connection body.

[0005] In the above-mentioned pressure-welded flexible connection structure of an outdoor disconnector, a plastic transparent plate is provided on the side wall of the water tank, and a marking line is provided on the side wall of the plastic transparent plate. The staff can observe the liquid level of the marking liquid inside the water tank through the plastic transparent plate. If the liquid level is obviously higher than the marking line, it proves that there is a protrusion in the area where the two flexible connection bodies abut against each other. If the liquid level is obviously lower than the marking line, it proves that there is a groove in the area where the two flexible connection bodies abut against each other.

[0006] In the above-mentioned pressure-welded soft connection structure of an outdoor disconnector, a rotating rod 1 and a rotating rod 2 are rotatably connected to the side wall of the inner cavity of the sliding rod, a ratchet and a transmission wheel 1 are welded on the outer peripheral wall of the rotating rod 1, a gear and a transmission wheel 2 are welded on the outer peripheral wall of the rotating rod 2, a sprocket is arranged between the transmission wheel 1 and the transmission wheel 2, the rotating gear drives the rotating rod 2 and the transmission wheel 2 to rotate, and the transmission wheel 1 drives the transmission wheel 1, the rotating rod 1 and the ratchet to rotate through the sprocket, and the rotating ratchet can scrape off the oxidation on the inner side of the depression.

[0007] In the above-mentioned pressure-welded soft connection structure of an outdoor isolating switch, a plurality of support rods are welded on the sides of the two mounting plates that are away from each other, and a plurality of mounting frames are welded on the side walls of each support rod, and a rotating rod three is rotatably connected to the inner side of each mounting frame, and a clamping rod is welded on the outer peripheral wall of each rotating rod three, and a plurality of springs three are connected to the side walls of each support rod, and each spring three is connected one-to-one between each clamping rod and the corresponding support rod side wall. When the sliding rod slides upward under the action of the elastic force of the spring one, the set gear will also move upward with the sliding rod. Since the clamping rod is inserted between two adjacent teeth on the outer peripheral wall of the gear, and the clamping rod is limited by the mounting frame, the clamping rod can only rotate downward with the rotating rod three as the axis but cannot rotate upward. It can be seen that when the gear moves upward, due to the influence of the clamping rod, the set gear will also rotate itself when moving upward.

[0008] In the above-mentioned pressure-welded soft-connection structure of an outdoor isolating switch, a main isolating switch body and an auxiliary isolating switch body are arranged on the top of the base plate, and two symmetrically arranged limit plates and two symmetrically arranged soft-connection bodies are fixedly mounted on the contacts of the main isolating switch body by screws. A worm drive structure is arranged on the top of the base plate, and the worm drive structure is electrically connected to the main isolating switch body and the auxiliary isolating switch body. After the detection is completed, the electric telescopic rod drives the scraper plate to reset to the initial position, and then the worm drive structure is operated to drive the main isolating switch body and the auxiliary isolating switch body to rotate towards each other, so that the contacts of the auxiliary isolating switch body move to between the areas where the two soft-connection bodies abut each other, thereby completing the closing action.

[0009] In the above-mentioned pressure-welded flexible connection structure of an outdoor disconnector, a rain shield is fixedly installed on the contact of the main disconnector body by screws, and the rain shield can protect the two flexible connection bodies.

[0010] In the above-mentioned pressure-welded flexible connection structure of an outdoor disconnector, several of the sleeves and the inner cavity of the water tank are filled with marking liquid, and the staff can observe the liquid level of the marking liquid inside the water tank through the plastic transparent plate.

[0011] Compared with the existing technology, the advantages of the pressure welding soft connection structure of the outdoor disconnector are:

[0012] 1. The scraper plate will scrape off the oxides in the mutually abutting area of ​​the two flexible connection bodies during movement, thereby improving the working efficiency of the flexible connection bodies; the sliding rod will penetrate into the inner side of the depression under the action of the elastic force of the spring, and then the sliding rod moving with the scraper will clean the oxides inside the depression, thereby enhancing the cleaning effect of the device on the oxides; the rotating ratchet can scrape off the oxides inside the depression, thereby further enhancing the cleaning effect of the device on the oxides;

[0013] 2. When the top of the sliding rod abuts against the inside of the groove, the internal space of the corresponding sleeve increases, and the marking liquid inside the corresponding water tank will enter the increased space inside the sleeve under the action of spring 2 and the piston plate, and the marking liquid inside the corresponding water tank will decrease. The staff can observe the liquid level of the marking liquid inside the water tank through the plastic transparent plate. If the liquid level is obviously higher than the marking line, it proves that there is a bulge in the area where the two soft connection bodies abut against each other. If the liquid level is obviously lower than the marking line, it proves that there is a groove in the area where the two soft connection bodies abut against each other. The staff can repair or replace the corresponding soft connection body accordingly. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0027] Reference Figure 1-Figure 10 A pressure-welded soft connection structure of an outdoor disconnector, a bottom plate 1, two symmetrical soft connection bodies 2 are arranged on the top of the bottom plate 1, two symmetrical limit plates 3 are arranged on the side of the two soft connection bodies 2 away from each other, two symmetrical mounting frames 4 are fixedly connected between the two limit plates 3 by screws, electric telescopic rods 5 are fixedly installed on the side walls of the two mounting frames 4, and a scraper plate 6 is fixedly installed between the telescopic ends of the two electric telescopic rods 5. The two electric telescopic rods 5 drive the scraper plate 6 to move in the direction where the two soft connection bodies 2 abut against each other, and the scraper plate 6 will scrape off the oxide in the abutment area of ​​the two soft connection bodies 2 during the movement.

[0028] Furthermore, square frames 33 are welded at both upper and lower ends of the scraper plate 6, two mounting plates 7 are welded on the side wall of the inner cavity of the scraper plate 6, and a plurality of sleeves 8 are fixedly installed on the side away from each other of the two mounting plates 7, and a slide rod 9 is slidably arranged in the inner cavity of each sleeve 8, and a spring 10 is connected to the bottom of the inner cavity of each sleeve 8, and each spring 10 is connected one by one between the bottom of the inner cavity of each sleeve 8 and the bottom of the slide rod 9. In the process of the scraper plate 6 entering the area where the two soft connection bodies 2 abut each other, the spring 10 is first compressed by force, and the top of the slide rod 9 is contracted to the square In the frame 33; if there is a depression in the area where the two soft connection bodies 2 abut each other, the slide bar 9 is set to penetrate into the inner side of the depression under the action of the elastic force of the spring 10, and then the oxide inside the depression is cleaned with the help of the slide bar 9 that moves with the scraper; the side wall of the inner cavity of the slide bar 9 is rotatably connected with a rotating rod 17 and a rotating rod 2 18, and a ratchet 19 and a transmission wheel 1 20 are welded on the outer peripheral wall of the rotating rod 17, and a gear 21 and a transmission wheel 22 are welded on the outer peripheral wall of the rotating rod 2 18. A sprocket 23 is wound between the transmission wheel 1 20 and the transmission wheel 22, and the two mounting plates 7 are away from each other. A plurality of support rods 24 are welded on the side wall of each support rod 24, and a plurality of mounting frames 25 are welded on the side wall of each support rod 24. A rotating rod 26 is rotatably connected to the inner side of each mounting frame 25. A clamping rod 27 is welded on the outer peripheral wall of each rotating rod 26. A plurality of springs 28 are connected to the side wall of each support rod 24, and each spring 28 is connected one by one between each clamping rod 27 and the corresponding side wall of the support rod 24. When the slide bar 9 slides upward under the action of the elastic force of the spring 10, the gear 21 set will also move upward with the slide bar 9. Since the clamping rod 27 is plugged into the outer peripheral wall of the gear 21, the gear 21 is rotated to rotate with the inner side wall of each support rod 24. Between two adjacent teeth on the peripheral wall, and the clamping rod 27 is limited by the mounting frame 25, so that the clamping rod 27 can only rotate downward with the rotating rod three 26 as the axis but cannot rotate upward. It can be seen that when the gear 21 moves upward, due to the influence of the clamping rod 27, the set gear 21 will also rotate when moving upward. The rotating gear 21 drives the rotating rod two 18 and the transmission wheel two 22 to rotate, and the transmission wheel one 20 drives the transmission wheel one 20, the rotating rod one 17 and the ratchet 19 to rotate through the sprocket 23. The rotating ratchet 19 can scrape off the oxidation on the inner side of the depression.

[0029] Furthermore, a collecting pipe 11 is connected between the bottoms of several sleeves 8, a water tank 12 is fixedly installed on the side wall of the scraper plate 6, and the collecting pipe 11 is connected to the water tank 12 on one side outside the scraper plate 6, a spring 2 13 is connected to the top of the inner cavity of the water tank 12, a piston plate 14 is connected to the bottom of the spring 2 13, several sleeves 8 and the inner cavities of the water tank 12 are filled with marking liquid, a plastic transparent plate 15 is arranged on the side wall of the water tank 12, and a marking line 16 is arranged on the side wall of the plastic transparent plate 15, when the top of the sliding rod 9 abuts against the inner side of the groove, the internal space of the corresponding sleeve 8 increases, and the marking liquid inside the corresponding water tank 12 will enter the enlarged space inside the sleeve 8 under the action of the spring 2 13 and the piston plate 14, and the marking liquid inside the corresponding water tank 12 will decrease, and the staff can observe the liquid level of the marking liquid inside the water tank 12 through the plastic transparent plate 15.

[0030] Furthermore, a main isolating switch body 29 and an auxiliary isolating switch body 30 are arranged on the top of the base plate 1, and two symmetrically arranged limit plates 3 and two symmetrically arranged soft connection bodies 2 are fixedly mounted on the contacts of the main isolating switch body 29 by screws. A worm drive structure 31 is arranged on the top of the base plate 1, and the worm drive structure 31 is electrically connected to the main isolating switch body 29 and the auxiliary isolating switch body 30. After the detection is completed, the electric telescopic rod 5 drives the scraper plate 6 to reset to the initial position, and then the worm drive structure 31 is operated to drive the main isolating switch body 29 and the auxiliary isolating switch body 30 to rotate towards each other, so that the contacts of the auxiliary isolating switch body 30 move to the area where the two soft connection bodies 2 abut against each other, so as to complete the closing action; a rain cover 32 is fixedly mounted on the contacts of the main isolating switch body 29 by screws, and the rain cover 32 can protect the two soft connection bodies 2.

[0031] Working principle: before the staff performs the closing operation, they first drive the two electric telescopic rods 5 to extend, and the two electric telescopic rods 5 drive the scraper plates 6 to move in the direction where the two flexible connection bodies 2 abut against each other. The scraper plates 6 scrape off the oxides in the abutting area of ​​the two flexible connection bodies 2 during the movement, thereby improving the working efficiency of the flexible connection bodies 2;

[0032] In addition, when the scraper plate 6 enters the area where the two soft connection bodies 2 abut against each other, the spring 10 is first compressed, and the top of the slide bar 9 is retracted into the frame 33; if there is a depression in the area where the two soft connection bodies 2 abut against each other, the slide bar 9 is penetrated into the inside of the depression under the action of the elastic force of the spring 10, and then the slide bar 9 that moves with the scraper is used to clean the oxide inside the depression, so as to enhance the cleaning effect of the device on the oxide;

[0033] In addition, when the slide bar 9 slides upward under the action of the elastic force of the spring 10, the set gear 21 will also move upward with the slide bar 9. Since the clamping rod 27 is inserted between two adjacent teeth on the outer peripheral wall of the gear 21, and the clamping rod 27 is limited by the mounting frame 25, the clamping rod 27 can only rotate downward with the rotating rod 3 26 as the axis but cannot rotate upward. It can be seen that when the gear 21 moves up, due to the influence of the clamping rod 27, the set gear 21 will also rotate when moving up. The rotating gear 21 drives the rotating rod 2 18 and the transmission wheel 22 to rotate. The transmission wheel 1 20 drives the transmission wheel 1 20, the rotating rod 17 and the ratchet 19 to rotate through the sprocket 23. The rotating ratchet 19 can scrape off the oxidation on the inner side of the depression, wherein the scraped oxide will fall to the inner side of the frame 33, thereby further enhancing the cleaning effect of this device on the oxide.

[0034] After the scraper plate 6 completes the scraping operation, the electric telescopic rod 5 drives the scraper plate 6 to return to the area between the two soft connection bodies 2 abutting each other. At this time, the slide bar 9 adaptively abuts against the inner side of the groove under the action of the spring 10;

[0035] Since the inner cavities of the sleeve 8 and the water tank 12 are filled with marking liquid, and several sleeves 8 are connected to the water tank 12 through the collecting pipe 11, when the top of the sliding rod 9 abuts against the inner side of the groove, the internal space of the corresponding sleeve 8 increases, and the marking liquid inside the corresponding water tank 12 will enter the increased space inside the sleeve 8 under the action of the spring 13 and the piston plate 14, and the marking liquid inside the corresponding water tank 12 will decrease. The staff can observe the liquid level of the marking liquid inside the water tank 12 through the plastic transparent plate 15. If the liquid level is obviously higher than the marking line 16, it proves that there is a bulge in the area where the two soft connection bodies 2 abut against each other. If the liquid level is obviously lower than the marking line 16, it proves that there is a groove in the area where the two soft connection bodies 2 abut against each other, and the staff can repair or replace the corresponding soft connection body 2 accordingly.

[0036] After the detection is completed, the electric telescopic rod 5 drives the scraper plate 6 to reset to the initial position, and then the worm drive structure 31 is operated to drive the main isolating switch body 29 and the auxiliary isolating switch body 30 to rotate towards each other, so that the contacts of the auxiliary isolating switch body 30 move to the area where the two soft connection bodies 2 abut each other, thereby completing the closing action.

[0037] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are conventional means well known to those skilled in the art.

[0038] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
