Description

Technical Field

[0001] The utility model relates to a fast-installed cathode wire connection structure, belonging to the field of electrostatic precipitator equipment. Background Art

[0002] Common cathode wire types for electrostatic precipitators on the market include: barb wire, bone spur wire, serrated wire, spiral wire, needle-pricked wire, etc. Among them, barb wire, bone spur wire, and serrated wire are all fixed to the cathode frame by bolt fastening, which usually requires drilling holes on the cathode frame to accommodate bolt fixation; the needle-pricked wire is connected to the cathode frame beam by welding, but due to the width limitation of the needle-pricked wire and the beam, the weld length is relatively short. The above-mentioned fixed connection methods all require a lot of installation work, and during the operation of the electrostatic precipitator, due to long-term vibration and cleaning, the nuts will loosen and fall off or the welds will fail, eventually leading to faults such as disconnection and electric field short circuit.

[0003] Chinese patent publication number CN205392758U discloses a tubular cathode wire non-welding connection device, comprising a cathode frame, a circular hole connecting plate, a cathode wire flat plate, hole bolts, slotted nuts, flat washers, spring washers, L-shaped steel wire pins and a waist-shaped hole connecting plate. The cathode frame and the two connecting plates are fixed by resistance welding, and the two connecting plates are fixed to the cathode wire flat plate by hole bolts, slotted nuts, spring washers or flat washers. The L-shaped steel wire pins are inserted into the slots of the slotted nuts and the small holes of the hole bolts, and then bent and tightened to ensure that the bolts and nuts will not fall off, and no electric welding is required in the workshop or on site. Although the patent reduces the number of welds and simplifies the installation process, once the cathode frame and the connecting plate are fixed, it is impossible to adjust the position of the cathode wire, nor can the connection between the cathode wire and the connecting plate or the connection plate and the cathode frame be adjusted separately. The disassembly and assembly steps are cumbersome and not conducive to operation on the construction site. Utility Model Content

[0028] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] See also Figure 1-8 A quick-install cathode wire connection structure includes a cathode frame 1 composed of four rods 11 connected end to end, a middle rod 12 fixedly connected to the middle of the cathode frame 1, and a cathode wire 2 arranged between the middle rod 11 and the rod 12 opposite to it.

[0030] Furthermore, the middle rod 12 and the outer periphery of the rod body 11 opposite to the middle rod 12 are both installed with a clamping part 3 composed of two clamping plates 31. The middle rod 12 and several clamping parts 3 on the rod body 11 opposite to the middle rod 12 are positioned opposite to each other, and cathode wires 2 are arranged between the clamping parts 3 that are positioned opposite to each other.

[0031] When the two clamping plates 31 are tightened by the clamping bolts 32, the clamping member 3 is fixed at a certain position of the middle rod 12 or the rod body 11; when the clamping bolts 32 do not tighten the two clamping plates 31, the clamping member 3 can slide along the axial direction of the middle rod 12 or the rod body 11, and can rotate along the radial direction of the middle rod 12 or the rod body 11, so as to adjust the clamping member 3 to the position corresponding to the cathode line 2, so as to facilitate the connection operation between the clamping member 3 and the cathode line 2.

[0032] When the clamping member 3 is set on the middle rod 12, the two clamping plates 31 are arc-shaped plates, and the middle rod 12 is placed between the two arc-shaped plates. The two ends of each arc-shaped plate extend out ear plates 4 in opposite directions. The clamping bolts 32 and the two ear plates 4 control the clamping or loosening between the two through the clamping bolts 32, thereby tightening or separating the clamping member 3 and the middle rod 12.

[0033] When the clamping member 3 is arranged on the rod body 11 opposite to the middle rod 12, the two clamping plates 31 are special-shaped arc plates, and the rod body 11 is placed between the two special-shaped arc plates; one end of each special-shaped arc plate forms a fitting portion 5, and the other end of the special-shaped arc plate extends outward to form an ear plate 4, and the ear plate 4 cooperates with the clamping bolt 32 to fasten the clamping member 3 to the rod body 11. At this time, the fitting portions 5 of the two special-shaped arc plates can cooperate and lock with each other to prevent the two special-shaped arc plates from loosening and separating, thereby clamping the rod body 11.

[0034] Furthermore, the engaging portion 5 is an L-shaped plate, the longitudinal edge 51 of the L-shaped plate is fixedly connected to the special-shaped arc plate, and an engaging groove 53 is left between the transverse edge 52 of the L-shaped plate and the special-shaped arc plate. The L-shaped plates on the two special-shaped arc plates are arranged opposite to each other. When the clamping member 3 is fixed on the rod body 11, the transverse edge 52 on one special-shaped arc plate is engaged in the engaging groove 53 of the other special-shaped arc plate.

[0035] Furthermore, the free end of each ear plate 4 extends outward to form a connecting piece 6. When the two clamping plates 31 are connected by the clamping bolts 32, the ear plates 4 on the two clamping plates 31 are overlapped, and at the same time, the connecting pieces 6 on the two ear plates 4 are overlapped. The end of the cathode wire 2 with the through hole 21 is arranged between the two overlapping connecting pieces 6, and the two connecting pieces 6 are fastened to the cathode wire 2 by the connecting bolts 61.

[0036] Furthermore, a groove 7 is provided between each ear plate 4 and the connecting piece 6 to which it is connected. When the clamping member 3 is fastened to the middle rod 12 or the rod body 11, the groove 7 prevents the thickness of the cathode wire 2 end from affecting the clamping state of the clamping member 3 when the two connecting pieces 6 are fixedly connected to the cathode wire 2. At the same time, when the position of the clamping member 3 needs to be adjusted, the clamping member 3 can be moved or fixed by simply tightening the clamping bolt 32, thereby adjusting the position of the clamping member 3 without affecting the fastening connection between the cathode wire 2 and the clamping member 3. The clamping piece 31, ear plate 4, and connecting piece 6 can be made of high-quality spring steel sheets with strong elasticity and resilience, ensuring the reliability of the fastening connection of the clamping member 3 and making the connection between the cathode wire 2 and the cathode frame 1 more secure.

[0037] Furthermore, the clamping bolt 32 and the connecting bolt 61 are both bolts with sockets that cooperate with the cotter pin 8. The bolts and nuts are locked together to achieve the clamping between the clamping plates 31. In order to ensure the clamping state, a slotted nut 9 can be sleeved on the bolt and fastened to its thread. The two arms of the cotter pin 8 are successively passed through the notch 91 of the slotted nut 9 and the adjacent socket and then broken apart and bent to keep the position of the nut and the slotted nut 9 stable and prevent them from loosening, thereby ensuring the clamping state of the clamping member 3 and ensuring the tight connection between the cathode wire 2 and the two connecting plates 6.

[0038] The working principle of this utility model:

[0039] See also Figure 1-8 A number of corresponding holding pieces 3 are installed on the outer periphery of the middle rod 12 of the cathode frame 1 and the rod body 11 opposite to the middle rod 12.

[0040] The connection method of each clamping member 3 and the middle rod 12 is: the two arc-shaped plates are placed on both sides of the middle rod 12 and are arranged in contact with the outer periphery of the middle rod 12. At this time, the ear plates 4 at the ends of the two arc-shaped plates are overlapped, and the clamping bolts 32 pass through the two adjacent ear plates 4 in turn and are tightened with the nuts to fasten the clamping member 3 to the middle rod 12. At the same time, the connecting plates 6 on the two arc-shaped plates are overlapped.

[0041] The connection method of each clamping member 3 and the rod body 11 is: two special-shaped arc plates are placed on both sides of the rod body 11 and are arranged in contact with the outer periphery of the rod body 11. At this time, the horizontal edge 52 on one special-shaped arc plate is embedded in the embedding groove 53 of the other special-shaped arc plate, and the ear plates 4 at the other ends of the two special-shaped arc plates are overlapped. The clamping bolts 32 pass through the two adjacent ear plates 4 in turn and are tightened with the nuts to fasten the clamping member 3 to the rod body 11. At the same time, the connecting pieces 6 on the two special-shaped arc plates are overlapped.

[0042] Place the cathode wire 2 between the middle rod 12 and the rod body 11 opposite to the middle rod 12, and insert the two ends of the cathode wire 2 between the two adjacent connecting plates 6 respectively. Pass the connecting bolt 61 through the connecting plate 6, the through hole 21 of the cathode wire 2, and the other connecting plate 6 in sequence, and then tighten it with the nut to fasten the cathode wire 2 to the two connecting plates 6.

[0043] In order to ensure the tightening effect, the clamping bolt 32 and the connecting bolt 61 are both bolts with sockets that can cooperate with the cotter pin 8. The bolts are also threaded with slotted nuts 9. When the slotted nuts 9 are locked with the bolts, the two arms of the cotter pin 8 are passed through the slots 91 of the adjacent slotted nuts 9 in turn, and the sockets on the bolts are then bent to prevent the slotted nuts 9 and nuts from loosening.

[0044] When the position of the clamping member 3 needs to be adjusted, the cotter pin 8 placed on the ear plate 4 can be pulled out, and the slotted nut 9 and the nut on the ear plate 4 can be loosened in turn to make the clamping member 3 in a sliding or rotating state. After the position of the clamping member 3 is determined, the nut and the slotted nut 9 on the ear plate 4 can be tightened in turn, and then the cotter pin 8 can be inserted and the two arms of the cotter pin 8 can be opened.

Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
