Description

Technical Field

[0001] This invention belongs to the field of power safety, and specifically relates to a needle-type electric porcelain insulator anti-detachment device. Background Technology

[0002] Needle-type electric porcelain insulators are generally made of insulating parts (such as porcelain parts) and metal accessories (such as steel feet, iron caps, flanges, etc.) glued together with adhesive or mechanically clamped together.

[0003] Among them, the P-20T needle-type porcelain insulator (hereinafter referred to as P-20 insulator) is an important type of fixed support hardware in 10 kV lines. During installation and use, the nut is connected to the crossarm to support the conductor and insulated line. In the line design and construction, our company always adopts the single nut connection method of "one nut and one spring washer", which complies with relevant design specifications.

[0004] However, during line operation, the 10 kV line P-20 insulators often become tilted due to loose nuts. Some P-20 insulator nuts have even fallen off after loosening. In windy weather, the P-20 insulator screws can come out of the crossarm fixing holes, causing the line to be grounded and affecting the reliability of power supply. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a needle-type electric porcelain insulator anti-detachment device to solve the problem of P-20 insulators falling off due to loose nuts during use.

[0006] To solve the above problems, the present invention adopts the following technical solution:

[0007] A needle-type electric porcelain insulator anti-detachment device includes a U-shaped connector. The connector includes a side plate, a nut limiting plate and an anti-detachment plate vertically fixed to the same side of the side plate. The anti-detachment plate is positioned above the nut fixing plate and the two are parallel. The nut fixing plate is provided with a limiting groove adapted to the outer diameter of the nut. The anti-detachment plate is provided with an anti-detachment groove perpendicular to the side plate. An anti-detachment component is provided on the side of the anti-detachment plate away from the side plate to block the anti-detachment groove.

[0008] Furthermore, the thickness of the nut limiting plate is at least 1 cm.

[0009] Furthermore, the anti-detachment component includes a middle rod and connecting pieces disposed at both ends of the middle rod. The anti-detachment plate has cavities on both sides of the anti-detachment groove that are adapted to the connecting pieces. The sides of the cavities are connected to the anti-detachment groove. The thickness of the middle rod and the connecting pieces is the same and less than the height of the cavities. The two connecting pieces are disposed in the two cavities respectively.

[0010] Furthermore, a magnet is installed at the bottom of the cavity, and the connecting piece is made of iron.

[0011] Furthermore, the sum of the thicknesses of the magnet and the connecting piece is less than the height of the cavity.

[0012] Furthermore, an arc-shaped groove is provided on the side of the middle rod near the side plate.

[0013] Furthermore, the anti-detachment plate or nut limiting plate is threaded with tightening bolts, and the number of tightening bolts is at least two. The tightening bolts are symmetrically distributed with the anti-detachment groove or limiting groove as the center line.

[0014] Furthermore, the side plate, anti-detachment plate, and nut limiting plate are integrally molded.

[0015] Furthermore, the anti-detachment plate has a through hole, the direction of which is parallel to the side plate, and an anti-detachment component, which is a pin, is inserted into the through hole.

[0016] Furthermore, there are receiving grooves on the opposite sides of the bottom of the anti-detachment groove.

[0017] The significant beneficial effects achieved by this invention are as follows:

[0018] 1. The present invention provides a needle-type electric porcelain insulator anti-detachment device, comprising a U-shaped connector, the connector comprising a side plate, a nut limiting plate and an anti-detachment plate vertically fixedly connected to the same side of the side plate, the anti-detachment plate being disposed above the nut fixing plate and the two being parallel, the nut fixing plate being provided with a limiting groove adapted to the outer diameter of the nut, the anti-detachment plate being provided with an anti-detachment groove perpendicular to the side plate, and an anti-detachment component for sealing the anti-detachment groove being provided on the side of the anti-detachment plate away from the side plate. This application uses a C-shaped connector to be inserted into the crossarm. The upper limit groove of the connector is used to limit the hexagonal nut in the P-20 bottle to prevent it from rotating. The anti-detachment groove on the connector is used to accommodate the support rod in the P-20 bottle and to wrap the support rod inside the anti-detachment plate, preventing the connector from leaving the crossarm and losing its limit on the hexagonal nut in the P-20 bottle. Because of the anti-detachment plate, the connector will not rotate or leave the crossarm, so the hexagonal nut in the P-20 bottle can be effectively fixed, preventing the nut from loosening. This effectively solves the problem of the P-20 bottle falling off due to the nut loosening during use.

[0019] 2. The thickness of the nut limiting anti-detachment plate is at least 1cm. The thickness of the nut limiting plate can reserve the space occupied by the spring washer between the hexagonal nut and the crossbeam. This allows the upper end of the nut limiting plate to contact the bottom end of the crossbeam while still limiting the hexagonal nut.

[0020] 3. The dumbbell-shaped anti-detachment component is placed in the cavities on both sides of the anti-detachment groove to seal the groove, limit the support rod in the P-20 bottle, ensure that the connector is inserted into the crossbeam, limit the hexagonal nut, and prevent the P-20 bottle from falling off due to the hexagonal nut loosening.

[0021] 4. A magnet is fixedly connected inside the cavity to attract the connecting piece, which can attract the connecting piece inside the cavity, further preventing the connecting piece from detaching from the cavity and improving the connection strength between the connecting piece and the anti-detachment plate.

[0022] 5. The installation of the tightening bolt can improve the tightness between the connector and the crossarm. By tightening the tightening bolt, the anti-disengagement plate or nut limiting plate in the connector can be made to fit tightly against the crossarm, further improving the firmness of the connector on the crossarm.

[0038] Example 1

[0039] like Figure 1-4 As shown, a needle-type electric porcelain insulator anti-detachment device is installed on the crossarm 17 to fix the p-20 insulator. It includes a C-shaped plug-in component. The plug-in component includes a vertical side plate 1, a nut limiting plate 2 perpendicular to the same side of the side plate 1, and an anti-detachment plate 3. The anti-detachment plate 3 is located above the nut limiting plate 2 and parallel to both of them. In order to improve the overall strength, the side plate 1, the nut limiting plate 2, and the anti-detachment plate 3 are integrally formed.

[0040] Among them, the nut limiting plate 2 has a limiting groove 4 that matches the outer diameter of the nut. The limiting groove 4 is perpendicular to the side plate 1. The nut is a hexagonal nut 14 that is threaded onto the support rod 15 in the p-20 bottle. The width of the limiting groove 4 matches the outer diameter of the nut. The outer diameter of the nut refers to the distance between two opposite sides on the hexagonal nut 14.

[0041] An anti-detachment groove 5 is provided on the anti-detachment plate 3, perpendicular to the side plate 1. The anti-detachment groove 5 is used to accommodate the support rod 15 on the p-20 bottle. The width of the anti-detachment groove 5 is adapted to the diameter of the support rod 15. The anti-detachment groove 5 is located vertically above the limiting groove 4. An anti-detachment component 6 is provided on the side of the anti-detachment groove 5 away from the side plate 1 to seal the anti-detachment groove 5. After installation, the anti-detachment component 6 is located on the side of the support rod 15 away from the side plate 1 and is connected to the support rod 15. The support rod 15 in the p-20 bottle is provided with abutment protrusion 16 for limiting the support rod 15. Therefore, in order to facilitate the support rod 15 to enter the anti-detachment groove 5, there are receiving grooves 13 on the bottom of opposite sides of the anti-detachment groove 5 that are adapted to the abutment protrusion 16. The opening of the receiving groove 13 reduces the influence of the abutment protrusion 16 on the support rod 15 when the support rod 15 enters the anti-detachment groove 5, and can make the width of the anti-detachment groove 5 adapt to the diameter of the support rod 15.

[0042] After the P-20 bottle is installed on the crossarm 17, the upper limit groove 4 and the anti-detachment groove 5 of the connector are inserted into the nut and the support rod 15 respectively. The anti-detachment plate 3 and the nut limiting plate 2 in the connector clamp the crossarm 17. After the connector is inserted into the crossarm 17, the two opposite sides of the hexagonal nut 14 abut against the two sides inside the limiting groove 4. The support rod 15 is located in the anti-detachment groove 5. The anti-detachment component 6 blocks the side of the anti-detachment groove 5 away from the side plate 1 to prevent the connector from detaching from the crossarm 17. In this way, the limiting groove 4 can effectively limit the hexagonal nut 14 to prevent the hexagonal nut 14 from loosening. The upper part of the P-20 bottle is fixed to the wire and will not rotate. The hexagonal nut 14 is effectively fixed, and the loosening of the P-20 bottle due to the loosening of the nut on the P-20 bottle is avoided.

[0043] Specifically, in order to facilitate the limiting groove 4 to limit the hexagonal nut 14, the thickness of the nut limiting anti-detachment plate 3 is at least 1cm. The thickness of the nut limiting plate 2 can reserve the position occupied by the spring washer between the hexagonal nut 14 and the crossbeam 17, so that the upper end of the nut limiting plate 2 can contact the bottom end of the crossbeam while still limiting the hexagonal nut 14.

[0044] In this embodiment, the anti-detachment component 6 includes a middle rod 8 and connecting pieces 7 fixedly installed at both ends of the middle rod 8. The anti-detachment plate 3 has cavities 9 on both sides of the anti-detachment groove 5 that are adapted to the connecting pieces 7. The opposite sides of the two cavities 9 are connected to the anti-detachment groove 5. When the anti-detachment component 6 needs to seal the anti-detachment groove 5, the connecting pieces 7 at both ends of the middle rod 8 are placed into the cavities 9 respectively. The middle rod 8 seals the anti-detachment groove 5 as the connecting pieces 7 are placed. In order to prevent the connecting pieces 7 from leaving the cavity 9 due to external shaking or other factors after being placed in the cavity 9, the thickness of the connecting pieces 7 and the middle rod 8 is the same and less than the opening height of the cavity 9. In this way, when subjected to shaking or other influencing factors, the connecting pieces 7 need to jump out of the cavity 9 to leave. The outer side of the connecting pieces 7 has a certain friction with the inner wall of the cavity 9, which can effectively prevent the connecting pieces 7 from moving in the cavity 9, let alone jumping.

[0045] The anti-detachment groove 5 is mainly designed to accommodate the support rod 15 and prevent the connector from leaving the crossarm 17 by abutting the support rod 15 away from the side plate 1 through the anti-detachment part 6. Therefore, the middle rod 8 has an arc-shaped groove on the side close to the side plate 1, which facilitates abutting with the support rod 15.

[0046] After the connector is inserted into the crossarm 17 and the nut and support rod 15 are limited, in order to prevent gaps between the anti-detachment plate 3 and the crossarm 17, or between the nut limiting plate 2 and the crossarm 17, a tightening bolt 11 is threaded onto the anti-detachment plate 3 or the nut limiting plate 2. There are at least two tightening bolts 11, and the number of tightening bolts 11 is even. The tightening bolts 11 are symmetrically distributed with the anti-detachment groove 5 or the limiting groove 4 as the center line. The tightening bolts 11 are set perpendicular to the upper end of the anti-detachment plate 3 or the bottom end of the nut limiting plate 2. By setting the tightening bolts 11, when there are gaps between the anti-detachment plate 3 and the crossarm 17, or between the nut limiting plate 2 and the crossarm 17, the tightening bolts 11 can be turned to abut against the crossarm 17 instead of the anti-detachment plate 3 or the nut limiting plate 2, thus preventing the connector from loosening.

[0047] Working principle: After the P-20 bottle is installed on the crossarm 17, the worker holds the connector and aligns the anti-detachment groove 5 and the limiting groove 4 with the support rod 15 and the hexagonal nut 14 respectively, and inserts them into the crossarm 17. If the hexagonal nut 14 is misaligned and cannot enter the limiting groove 4, it can be adjusted by turning it so that the two opposite sides of the hexagonal nut 14 are parallel to the two sides of the limiting groove 4, so that it can enter the limiting groove 4. The spring washer between the nut and the crossarm 17 allows the hexagonal nut 14 to have a certain adjustment range. When the support rod 15 and the hexagonal nut 14 are both in the anti-detachment groove 5 and the limiting groove 4, the side plate 1 is pushed so that it abuts against the side of the crossarm 17. The two connecting pieces 7 are installed in the cavities 9 on both sides of the anti-detachment groove 5 respectively to limit the support rod 15. The installation work is then completed.

[0048] It should be noted that the crossarm 17 is generally made of angle iron, so the connector is designed in the shape of a c-shaped piece that can be inserted into the crossarm 17 to fix the hexagonal nut 14 in the p-20 bottle. Since the crossarm 17 is mass-produced and has relevant national standards, the position of the support rod 15 in the p-20 bottle installed on the crossarm 17 is fixed. By measuring the distance between the support rod 15 and the side of the crossarm 17, the position of the anti-detachment component 6 on the anti-detachment plate 3 can be determined, which facilitates mass production.

[0049] In summary, this application uses a U-shaped connector to be inserted into the crossarm 17. The upper limit groove 4 of the connector is used to limit the nut in the P-20 bottle to prevent the nut from rotating. The anti-detachment groove 5 on the connector is used to accommodate the support rod 15 in the P-20 bottle and the anti-detachment part 6 wraps the support rod 15 inside, preventing the connector from leaving the crossarm 17 and losing the limit on the nut in the P-20 bottle. Since the anti-detachment plate 3 is set, the connector will not rotate or leave the crossarm 17, so the nut in the P-20 bottle can be effectively fixed, preventing the nut from loosening. This effectively solves the problem of the P-20 bottle falling off due to the nut loosening during use.

[0050] Example 2

[0051] like Figure 5 , Figure 6 and Figure 7 As shown, a needle-type electric porcelain insulator anti-detachment device includes a U-shaped connector. The connector includes a vertically arranged side plate 1, an anti-detachment plate 3 and a nut limiting plate 2 fixed on the same side of the side plate 1. The anti-detachment plate 3 is located above the nut limiting plate 2 and is parallel to the nut limiting plate 2. In order to ensure the overall strength of the connector, the side plate 1, the anti-detachment plate 3 and the nut limiting plate 2 are integrally formed.

[0052] Among them, the nut limiting plate 2 has a limiting groove 4 that matches the outer diameter of the nut. The nut is a hexagonal nut 14 installed in the p-20 bottle. The outer diameter of the hexagonal nut 14 is the same as the width of the limiting groove 4. The outer diameter of the hexagonal nut 14 refers to the distance between two opposite faces on the hexagonal nut 14.

[0053] The anti-detachment plate 3 has an anti-detachment groove 5 perpendicular to the side plate 1. On the side of the anti-detachment plate 3 away from the side plate 1, an anti-detachment component 6 is installed to block the anti-detachment groove 5. The width of the anti-detachment groove 5 is adapted to the diameter of the support rod 15 in the p-20 bottle. The support rod 15 is accommodated by the anti-detachment groove 5 and the support rod 15 is restricted to the anti-detachment groove 5 by the anti-detachment component 6, thereby preventing the connector from leaving the crossbeam 17 and ensuring that the nut limiting plate 2 is effectively fixed to the hexagonal nut 14.

[0054] Since the hexagonal nut 14 in the p-20 bottle fixes the support rod 15, a spring washer fitted on the support rod 15 between the hexagonal nut 14 and the crossbeam 17 to increase the locking force of the hexagonal nut 14, in order to provide effective limiting for the hexagonal nut 14 and to prevent the distance between the anti-detachment plate 3 and the nut limiting plate 2 from being too large than the thickness of the crossbeam 17, the thickness of the nut limiting plate 2 is at least 1cm. By increasing the thickness of the nut limiting plate 2, the overlap with the hexagonal nut 14 in height is increased, and the setting of the spring washer causes the overlap between the nut limiting plate 2 and the hexagonal nut 14 to be low.

[0055] In this embodiment, a through hole 12 is provided on the anti-detachment plate 3. The opening direction of the through hole 12 is parallel to the side of the side plate 1. The anti-detachment component 6 is inserted into the through hole 12. The anti-detachment component 6 is a pin. The anti-detachment groove 5 is blocked by the anti-detachment component 6 being inserted into the through hole 12. The setting of the anti-detachment component 6 as a pin can prevent the anti-detachment component 6 from moving freely in the through hole 12 and effectively fix the position of the plug on the crossbeam 17.

[0056] To prevent the gap between the anti-detachment plate 3 and the nut limiting plate 2 from being greater than the thickness at the installation position in the p-20 bottle, a tightening bolt 11 is threaded onto the anti-detachment plate 3 or the nut limiting plate 2. There are at least two tightening bolts 11, and the number of tightening bolts 11 is even. The tightening bolts 11 are symmetrically distributed on the anti-detachment plate 3 or the nut limiting plate 2 with the anti-detachment groove 5 or the limiting groove 4 as the center line. The tightening bolts 11 are threaded onto the upper end of the anti-detachment plate 3 or the bottom end of the nut limiting plate 2. Both the anti-detachment plate 3 and the nut limiting plate 2 have threaded holes that match the tightening bolts 11. By tightening the tightening bolts 11, the crossarm 17 is brought into contact, ensuring that the anti-detachment plate 3 or the nut limiting plate 2 is tightly fitted to the crossarm 17, preventing the connector from wobbling on the crossarm 17. In this embodiment, the tightening bolts 11 are installed on the anti-detachment plate 3.

[0057] The support rod 15 of the p-20 bottle is provided with an abutment protrusion 16 located above the hexagonal nut 14. The abutment protrusion 16 limits the position of the support rod 15 to facilitate the fixation of the hexagonal nut 14. In order to avoid the abutment protrusion 16 on the support rod 15 from affecting the insertion of the anti-detachment plate 3, the bottom of the anti-detachment groove 5 is provided with receiving grooves 13 on opposite sides to accommodate the abutment protrusion 16. The receiving grooves 13 accommodate the abutment protrusion 16 on the support rod 15, which facilitates the insertion of the anti-detachment plate 3 and further improves the overall firmness of the insertion part on the crossbeam 17.

[0058] Working principle: After the P-20 bottle is installed on the crossarm 17, the worker holds the connector and aligns the anti-detachment groove 5 and the limiting groove 4 with the support rod 15 and the hexagonal nut 14 respectively, and inserts them into the crossarm 17. If the hexagonal nut 14 is misaligned and cannot enter the limiting groove 4, it can be adjusted by turning it so that the two opposite sides of the hexagonal nut 14 are parallel to the two sides of the limiting groove 4, so that it can enter the limiting groove 4. The spring washer between the nut and the crossarm 17 allows the hexagonal nut 14 to have a certain adjustment range. When the support rod 15 and the hexagonal nut 14 are both in the anti-detachment groove 5 and the limiting groove 4, push the side plate 1 so that it abuts against the side of the crossarm 17, and insert the anti-detachment component 6 into the through hole 12 to complete the sealing of the anti-detachment groove 5. The support rod 15 is located in the closed hole formed by the anti-detachment groove 5 and the anti-detachment component 6. Tighten the top bolt 11 so that the nut limiting plate 2 is tightly attached to the crossarm 17, and the installation work is completed.

[0059] It should be noted that the crossarm 17 is generally made of angle iron, so the connector is designed in the shape of a c-shaped piece that can be inserted into the crossarm 17 to fix the hexagonal nut 14 in the p-20 bottle. Since the crossarm 17 is mass-produced and has relevant national standards, the position of the support rod 15 in the p-20 bottle installed on the crossarm 17 is fixed. By measuring the distance between the support rod 15 and the side of the crossarm 17, the position of the anti-detachment component 6 on the anti-detachment plate 3 can be determined, which facilitates mass production.

[0060] In summary, this application uses a U-shaped connector to be inserted into the crossarm 17. The upper limit groove 4 of the connector is used to limit the nut in the P-20 bottle to prevent the nut from rotating. The anti-detachment groove 5 on the connector is used to accommodate the support rod 15 in the P-20 bottle and to wrap the support rod 15 inside the anti-detachment part 6, preventing the connector from leaving the crossarm 17 and losing the limit on the nut in the P-20 bottle. Since the anti-detachment plate 3 is set, the connector will not rotate or leave the crossarm 17, so the nut in the P-20 bottle can be effectively fixed, preventing the nut from loosening. This effectively solves the problem of the P-20 bottle falling off due to the loose nut during use, as well as similar situations that occur in other P-20 bottles.

[0061] Example 3

[0062] like Figure 8 As shown, the structure of this embodiment is roughly the same as that of embodiment 1. This embodiment is further optimized based on embodiment 1. In order to prevent the connecting piece 7 from leaving the cavity 9, a magnet 10 is fixedly connected to the bottom of the cavity 9. The material of the connecting piece 7 is iron. The magnet 10 attracts the connecting piece 7. By using the magnet 10 fixedly connected to the bottom of the cavity 9 to magnetically attract the connecting piece 7, the connecting piece 7 is further prevented from leaving the cavity 9, thus ensuring the stability of the connector.

[0063] Setting the sum of the thicknesses of magnet 10 and connecting piece 7 to be less than the height of cavity 9 can also provide further restraint for connecting piece 7, preventing connecting piece 7 from leaving cavity 9.

[0064] Currently, the technical solution of this application has undergone pilot testing, which is a small-scale experiment before the product is mass-produced. After the pilot testing was completed, a user survey was conducted on a small scale, and the survey results showed that user satisfaction was high. Now, preparations have begun for the formal production and industrialization of the product (including intellectual property risk warning surveys).
