Description

Technical Field

[0001] This invention relates to the field of surge arrester installation technology, and in particular to a novel surge arrester and its operating method. Background Technology

[0002] The primary function of a surge arrester is to prevent damage to electrical equipment from lightning or other overvoltage phenomena. When lightning strikes or an overvoltage occurs in the power grid, the surge arrester quickly identifies and directs the overvoltage through the equipment itself, rather than through the equipment requiring protection. It conducts these instantaneous high voltages to the ground through grounding, preventing damage to sensitive electronic equipment or the power system.

[0003] Surge arresters are typically installed at the power input end of a building or in a power distribution system to prevent lightning from directly entering the equipment through the power system. In existing technologies, surge arrester installation mostly involves drilling holes later and then installing the base using expansion bolts. During installation, it is easy to drill into the reinforcing steel bars, or the construction is difficult due to the excessive hardness of the concrete used in the building. Based on the various installation difficulties encountered in existing technologies, we propose a new type of surge arrester and its working method. Summary of the Invention

[0004] To address the technical problem that difficulties in drilling holes during the installation of surge arresters lead to overall instability after installation, this invention adopts the following technical solution: To achieve the above-mentioned objectives, the technical solution adopted by this invention is as follows: Firstly, a novel surge arrester is provided, comprising a mounting chassis. Stepped holes are respectively formed near the four corners of the upper surface of the mounting chassis. A strip-shaped support column is fixed in the middle of the upper surface of the mounting chassis, and an anti-detachment block is fixed to the top of the strip-shaped support column. The length and width of the anti-detachment block are both larger than the dimensions of the top of the strip-shaped support column. A slotted clip is slidably engaged with the outer wall of the top of the anti-detachment block, and an arc-shaped hinge groove is formed near the two side edges of the top of the slotted clip. A gear-shaped antenna socket is rotatably connected to each of the two arc-shaped hinge grooves. Two U-shaped double-ended screws with upward openings and parallel to each other are inserted into the four stepped holes. The main bodies of the two U-shaped double-ended screws are located below the mounting chassis. The bottom of each U-shaped double-ended screw has a wavy structure, which not only prevents it from falling off but also improves the gripping force after being buried in concrete. When the device is installed on two parallel rods, it can provide a good tightening and anti-falling effect. Two connecting rods are welded between the bottoms of the two U-shaped double-ended screws. Locking nuts are screwed into the tops of the two U-shaped double-ended screws near the stepped holes. By setting two U-shaped double-ended screws welded together, before installation, you only need to fix the two U-shaped double-ended screws together to the top of the steel mesh, and expose the four threaded ends during pouring. After the concrete has solidified, the installation base and the channel-shaped clamp can be installed simply. The installation is convenient and stable.

[0005] A further feature of this invention is that the lower surface of the mounting chassis is provided with symmetrical side retaining strips near the two side edges, and each of the two side retaining strips has an arc-shaped groove reserved on the opposite side. The two ends of the side retaining strips are respectively provided with round holes that are adapted to the outer diameter of the U-shaped double-ended screw, that is, the side retaining strips can be sleeved on the vertical rod of the U-shaped double-ended screw. The side retaining strips are made of rubber material. By providing the two side retaining strips, the pre-tightening pressure can be increased when the mounting chassis is screwed in, and it is also convenient to level the surface of the mounting chassis.

[0006] A further feature of this invention is that the upper surface of the side clips has anti-slip protrusions near both the front and rear ends, and the lower surface of the mounting base has positioning holes that match the shape of the anti-slip protrusions. The positioning holes have multiple sets, which allows the distance between the two side clips to be changed. Thus, when the device needs to be installed on a cylindrical base, it can adapt to cylindrical bases of different diameters.

[0007] A further feature of this invention is that the anti-detachment block has protruding blocks near its two side edges on the front side, and limiting slots corresponding to the protruding blocks are respectively provided at the junction of the bottom of the slots on both sides of the opposite slotted component and the front side; a horizontally extending slot is provided in the middle of the back side of the anti-detachment block, and coaxial cylindrical insertion holes are provided on the left and right sides of the anti-detachment block, which are connected to the horizontal slot; a bullet-shaped locking pin is slidably connected to the opening of each of the two cylindrical insertion holes, and a hemispherical head is provided at the end of the locking pin away from the horizontal slot; the vertical grooves on the opposite sides of the slotted component are respectively provided. The inner wall is provided with limiting holes that match the hemispherical head; a return spring is fixed between the other end of the locking pin and the bottom of the cylindrical insertion hole 2; a screw is fixed at the opening of the horizontal slot, and a self-locking screw hole is provided in the middle of the screw; a winding screw rod extending horizontally into the bottom of the horizontal slot is screwed into the self-locking screw hole, and two steel wires are fixed on the outer wall of the winding screw rod near the cylindrical insertion hole 2, which are centrally symmetrically distributed. The two steel wires pass through the corresponding return springs and are fixed to the end of the locking pin on their respective sides; the distance between the cylindrical insertion hole 2 and the protruding block is equal to the distance between the limiting hole and the limiting slot.

[0008] A further feature of this invention is that the entire screw is embedded inside the horizontal slot, and the end of the winding screw away from the steel wire has a plum blossom-shaped embedded groove. A rubber plug is inserted at the opening of the horizontal slot. With this design, it can not only be waterproof and rustproof, but also prevent theft and falling off. A special wrench is required to turn the winding screw to retract the two locking pins.

[0009] A further feature of this invention is that the upper surface of the slotted clip has vertical cylindrical sliding holes near the four corners, which penetrate the upper and lower sides of the slotted clip. A threaded plug is screwed to the top of each cylindrical sliding hole, and a retaining spring is fixed to the lower surface of each threaded plug. A sliding rod is fixed to the bottom end of each retaining spring, and a U-shaped roller groove is provided at the bottom end of each sliding rod. Rollers are rotatably connected within each U-shaped roller groove. The upper surface of the mounting base has parallel rectangular grooves near the left and right edges. Four rollers rest on the rectangular grooves, and the width of the rollers is less than the width of the rectangular grooves. Trapezoidal sliding strips are embedded in both rectangular grooves. The mounting base, the strip support column, and the anti-detachment block constitute a support base. By providing four rollers that abut against the inclined surface of the trapezoidal sliding strips, the slotted clip can be more tightly connected to the support base.

[0010] A further feature of this invention is that a convex sliding groove is formed in the middle of the upper surface of the slotted clip to connect two arc-shaped hinge slots. Bearing grooves are formed on the front and rear edges of the top opening of each arc-shaped hinge slot on the upper surface of the slotted clip. Each bearing groove contains a bearing assembly. Coaxial shafts are pre-reserved at the center of the front and rear sides of the antenna socket, and these shafts are rotatably connected to the corresponding bearing assemblies. Teeth are pre-reserved on the opposite side arc surfaces of the two antenna sockets. Two symmetrically positioned abutting posts are slidably connected within the sliding groove of the convex sliding groove. A compression spring is fixed between the two abutting posts. A toothed groove is pre-reserved at the end of each abutting post near the teeth to engage with the teeth. An upwardly protruding actuating piece is pre-reserved on the outer wall of each abutting post. A cylindrical mounting head for installing a lightning rod is pre-reserved near the top of the circumferential outer wall of each of the two antenna sockets. A threaded hole is formed at the top of each cylindrical mounting head.

[0011] A further feature of this invention is that the left and right sides of the slotted clip are provided with the same through hole near the arc-shaped hinge groove, and mounting blocks are reserved below the openings of the through hole on both sides of the slotted clip. Two double-position terminals are fixed on the upper surfaces of the two mounting blocks, and the same metal connecting rod is fixed between the two double-position terminals. The metal connecting rod is inserted into the through hole. A metal plate is fixed at the bottom of the threaded hole, and a conical spring is fixed at the top of the metal plate. A flexible wire communicating with the outside is fixed on the lower surface of the metal plate, and the end of the flexible wire away from the metal plate is electrically connected to the corresponding double-position terminal. Through the metal connecting rod and the double-position terminals at both ends, it is easier to install the grounding wire and connect them to each other when installing multiple devices.

[0012] A further feature of this invention is that the upper surface of the external threaded plug is provided with an internal hexagonal groove in the middle, and the external threaded plug is made of plastic material. The outer wall of the external threaded plug is wrapped with PTFE tape. By using the external threaded plug made of plastic material and the PTFE tape wrapped around its outer wall, rainwater can be prevented from seeping into the cylindrical sliding hole.

[0013] Secondly, a novel method for operating a surge arrester is provided, including the following steps: S1: Before use, assemble two U-shaped double-ended screws into a group according to the spacing of the stepped holes, and weld them together with a connecting rod in the middle. Then, fix the two U-shaped double-ended screws together to the top of the steel cage, and leave four vertical threaded ends when pouring concrete. After the concrete has set, fix the support base to the protruding threaded ends with lock nuts. If this new type of surge arrester is to be installed later, simply screw the mounting base and U-shaped double-ended screws to a fixed strip-shaped object with lock nuts. S2: Then slide the slotted clip from back to front onto the anti-detachment block until the two limiting holes on the inner wall of the slotted clip are engaged with the hemispherical head of the locking pin. S3: Finally, connect the two adjacent double-position terminals of this device with a wire, then screw the lightning rod into the bottom of the threaded hole at the top of the antenna socket until it presses against the conical spring at the bottom of the hole. Finally, squeeze the two levers in the middle at the same time to adjust the angle between the two lightning rods. After adjustment, release the two levers.

[0014] The beneficial effects of this invention are as follows: 1. By setting two U-shaped double-ended screws welded together, before installation, you only need to fix the two U-shaped double-ended screws together to the top of the steel mesh, and expose the four threaded ends during pouring. After the concrete has solidified, you can simply install the base plate and the channel-shaped clamps. The installation is convenient and stable.

[0015] 2. By setting a locking pin and a matching limiting hole on the inner wall of the slotted clip, when installing the slotted clip as a whole, simply push the slotted clip horizontally from back to front until you feel the locking pin engage in the limiting hole, making installation convenient.

[0016] 3. By setting two antenna sockets that are rotatably connected in the arc-shaped hinge slot, when it is necessary to install the lightning rod, it can be simply screwed into the threaded hole. The tilt angle of the two lightning rods can be adjusted, thereby changing the lightning protection range as needed. Attached Figure Description

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] In this embodiment, refer to Figures 1-11This solution provides a novel surge arrester, comprising a mounting base 1. Stepped holes 103 are respectively opened at the four corners of the upper surface of the mounting base 1. A strip-shaped support column 14 is fixed in the middle of the upper surface of the mounting base 1. The length direction of the strip-shaped support column 14 is consistent with the width direction of the mounting base 1. An anti-detachment block 13 is fixed at the top of the strip-shaped support column 14. The length and width of the anti-detachment block 13 are both larger than the top dimension of the strip-shaped support column 14. A slotted clip 3 is slidably engaged on the outer wall of the top of the anti-detachment block 13. An arc-shaped hinge groove 305 is opened near the two side edges of the top of the slotted clip 3. A gear-shaped antenna socket 5 is rotatably connected to each of the two arc-shaped hinge grooves 305. Two U-shaped double-ended screws 15 with upward openings and parallel to each other are inserted into the four stepped holes 103. The main body of the head screw 15 is located below the mounting base 1. The bottom of both U-shaped double-headed screws 15 is designed with a wave-shaped structure, which not only prevents them from falling off but also improves the gripping force after being buried in the concrete. When the device is installed on two parallel rods, it can provide a good tightening and anti-falling effect. Two connecting rods are welded between the bottoms of the two U-shaped double-headed screws 15. Locking nuts 102 are screwed onto the tops of the two U-shaped double-headed screws 15 near the stepped hole 103. By setting two U-shaped double-headed screws 15 welded together, before installation, it is only necessary to fix the two U-shaped double-headed screws 15 together to the top of the steel mesh, and expose the four threaded ends during pouring. After the concrete has solidified, the mounting base 1 and the grooved clamp 3 can be installed simply. The installation is convenient and stable.

[0021] The mounting base 1 has two symmetrical side retaining strips 16 on its lower surface near the two side edges. Each side retaining strip 16 has an arc-shaped groove on its opposite side. The two ends of the side retaining strip 16 are respectively provided with round holes that match the outer diameter of the U-shaped double-ended screw 15. That is, the side retaining strip 16 can be fitted onto the vertical rod of the U-shaped double-ended screw 15. The side retaining strip 16 is made of rubber material. The two side retaining strips 16 can increase the pre-tightening pressure when the mounting base 1 is screwed in, and also facilitate the leveling of the surface of the mounting base 1.

[0022] Reference Figure 2 , Figure 6 , Figure 7 The upper surface of the side clip 16 has anti-slip protrusions 161 near both the front and rear ends, and the lower surface of the mounting base 1 has positioning holes 101 that are adapted to the shape of the anti-slip protrusions 161. There are multiple sets of holes in the positioning holes 101, so that the distance between the two side clips 16 can be changed. Therefore, when the device needs to be installed on a cylindrical base, it can adapt to cylindrical bases of different diameters.

[0023] Reference Figure 2 , Figure 9 , Figure 11 The anti-detachment block 13 has protruding blocks 132 near the two side edges on the front side, and limiting slots 12 corresponding to the protruding blocks 132 are respectively opened at the junction of the bottom of the slots on both sides of the groove-shaped card 3 and the front side; a horizontal slot 131 extending forward is opened in the middle of the back side of the anti-detachment block 13, and coaxial cylindrical insertion holes 136 communicating with the horizontal slot 131 are respectively opened on the left and right sides of the anti-detachment block 13. A locking pin 133 with a bullet-shaped structure is slidably connected to the opening of the two cylindrical insertion holes 136, and a hemispherical head is reserved at the end of the locking pin 133 away from the horizontal slot 131. Limiting holes 301 matching the hemispherical heads are respectively opened on the vertical inner walls on both sides of the groove-shaped card 3; a return spring 135 is fixed between the other end of the locking pin 133 and the bottom of the cylindrical insertion hole 136. A screw connector 134 is fixedly installed at the opening of hole 131, and a self-locking screw hole is provided in the middle of the screw connector 134. A winding screw 17 is screwed into the self-locking screw hole and extends horizontally into the bottom of the horizontal slot 131. Two steel wires 22 are fixed on the outer wall of the winding screw 17 near the cylindrical insertion hole 136. The two steel wires 22 pass through the corresponding return spring 135 and are fixed to the end of the locking pin 133 on the corresponding side. The distance between the cylindrical insertion hole 136 and the protruding block 132 is equal to the distance between the limiting hole 301 and the limiting slot 12. By setting the locking pin 133 and the limiting hole 301 that matches it on the inner wall of the slotted clip 3, when installing the slotted clip 3 as a whole, you only need to push the slotted clip 3 horizontally from back to front until you feel the locking pin 133 being inserted into the limiting hole 301. The installation is convenient.

[0024] Reference Figure 2 The screw connector 134 is fully embedded inside the horizontal slot 131, and the end of the winding screw 17 away from the steel wire 22 is provided with a plum blossom-shaped embedded groove. The opening of the horizontal slot 131 is plugged with a rubber plug. With this setting, it can not only play a role in waterproofing and rust prevention, but also play a role in preventing theft and falling off. A special wrench is required to turn the winding screw 17 to retract the two locking pins 133.

[0025] Reference Figure 6 , Figure 10 , Figure 11The upper surface of the slotted clip 3 has vertical cylindrical sliding holes 302 near the four corners, which extend through the upper and lower sides of the slotted clip 3. A threaded plug 9 is screwed to the top opening of each cylindrical sliding hole 302, and a retaining spring is fixed to the lower surface of each threaded plug 9. A sliding rod 18 is fixed to the bottom end of each retaining spring. All sliding rods 18 have U-shaped roller grooves at their bottom ends, and rollers 19 are rotatably connected within each U-shaped roller groove. The upper surface of the mounting base 1 near the left... Parallel rectangular grooves 104 are provided on both right edges. Four rollers 19 are placed above the rectangular grooves 104, and the width of the rollers 19 is smaller than the width of the rectangular grooves 104. Trapezoidal slides 2 are embedded in both rectangular grooves 104. The mounting base 1, strip support column 14 and anti-detachment block 13 constitute a support base. By setting four rollers 19 that abut against the inclined surface of the trapezoidal slide 2, the entire grooved clip 3 can be more tightly connected to the support base.

[0026] Reference Figure 4 , Figure 6 and Figure 8 The upper surface of the slotted clip 3 has a convex groove 7 in the middle for connecting two arc-shaped hinge slots 305. Bearing grooves 303 are provided on the front and rear edges of the top opening of each arc-shaped hinge slot 305 on the upper surface of the slotted clip 3. Each bearing groove 303 contains a bearing assembly 21. Coaxial shafts 503 are pre-reserved at the center of the front and rear sides of the antenna socket 5, and the shafts 503 are rotatably connected to the corresponding bearing assemblies 21. Teeth 8 are pre-reserved on the arc surfaces of the two antenna sockets 5 on opposite sides. Two symmetrical abutment posts 601 are slidably connected within the groove of the convex groove 7, and a fixed distance is maintained between the two abutment posts 601. The same compression spring 20 has two retaining posts 601 with toothed grooves near the teeth 8 at one end, and the outer walls of the two retaining posts 601 have upwardly protruding actuating pieces 6. The outer circumference of the two antenna sockets 5 has cylindrical mounting heads 501 near the top for installing lightning rods. The top of the cylindrical mounting heads 501 is provided with threaded holes 502. By setting two antenna sockets 5 that are rotatably connected in the arc-shaped hinge groove 305, when lightning rods need to be installed, they only need to be screwed into the threaded holes 502. The tilt angle of the two lightning rods can be adjusted, so that the lightning protection range can be changed as needed.

[0027] Reference Figure 3 and Figure 5The slotted clip 3 has a common through hole 304 on both sides near the arc-shaped hinge groove 305. The slotted clip 3 has a mounting block 11 below the hole of the through hole 304 on both sides. The upper surface of the two mounting blocks 11 is fixed with a double terminal 10. The two double terminal 10s are fixed with the same metal connecting rod 1001. The metal connecting rod 1001 is inserted into the through hole 304. The bottom of the threaded hole 502 is fixed with a metal piece. The top of the metal piece is fixed with a conical spring 23. The lower surface of the metal piece is fixed with a flexible wire 4 that communicates with the outside. The end of the flexible wire 4 away from the metal piece is electrically connected to the corresponding double terminal 10. With the metal connecting rod 1001 and the double terminal 10 at both ends, it is easier to install the grounding wire and connect them to each other when installing multiple devices.

[0028] Reference Figure 4 The upper surface of the external threaded plug 9 is provided with an internal hexagonal groove in the middle. The external threaded plug 9 is made of plastic material and the outer wall of the external threaded plug 9 is wrapped with PTFE tape. The external threaded plug 9 made of plastic material, together with the PTFE tape wrapped around its outer wall, can prevent rainwater from seeping into the cylindrical sliding hole 302.

[0029] This solution also provides a novel method for operating a surge arrester, including the following steps: S1: Before use, assemble two U-shaped double-ended screws 15 into a group according to the spacing of the stepped holes 103, and weld them together with a connecting rod in the middle. Then, fix the two U-shaped double-ended screws 15 together to the top of the steel cage, and leave four vertical threaded ends when pouring concrete. After the concrete has set, fix the support base to the protruding threaded ends with lock nuts 102. If this new type of surge arrester is to be installed later, simply screw the mounting base 1 and the U-shaped double-ended screws 15 onto a fixed strip-shaped object with lock nuts 102. S2: Then slide the slotted clip 3 from back to front onto the anti-detachment clip 13 until the two limiting holes 301 on the inner wall of the slotted clip 3 are engaged with the protruding hemispherical head of the locking pin 133. S3: Finally, connect the two adjacent double-position terminals 10 of this device with wires, and then screw the lightning rod into the bottom of the threaded hole 502 at the top of the antenna socket 5 until it presses against the conical spring 23 at the bottom of the hole. Finally, squeeze the two toggle pieces 6 in the middle at the same time to adjust the angle between the two lightning rods. After adjustment, release the two toggle pieces 6.
