[0033] The power transmission line is long-term exposed to icing, dancing and other harsh environments, and icing and line dancing phenomena occur frequently. Due to the possible defects of overvoltage and voltage leakage of the strain clamp device, the risk of line breakage is greatly increased. For the power transmission and distribution lines crossing railways, first-class and above highways, and near gas stations, hidden dangers should be checked out and reinforcement rectification measures should be taken. In the case of single-phase double-bundle conductor line without DB adjustment plate (Double Bundle Adjustment Plate, a kind of fitting specially used to adjust and fix the spacing and arrangement of double-bundle conductor), backup clamp reinforcement cannot be installed, and the "double connection double hanging" protection measures cannot be implemented, which seriously affects the safe operation of the line and poses a great safety hazard.

[0034] Based on this, an embodiment of the present application provides a double-bundle conductor single-phase double-wedge type strain backup clamp device, which can realize the installation of a safe backup clamp reinforcement device in the case that the double-bundle conductor (i.e. two parallel arranged conductors) line has no hanging point. The double-bundle conductor single-phase double-wedge type strain backup clamp device provided by an embodiment of the present application will be described in detail below with reference to the accompanying drawings.

[0035] Referring to Figures 1 to 4 As shown in the figure, the double-bundle conductor single-phase double-wedge type strain backup clamp device provided by an embodiment of the present application includes a strain hanging plate 110, a positioning plate 130, an extension pull rod 120 and two groups of tensioning units; the strain hanging plate 110 is used to be connected with a triangular joint plate 300; the positioning plate 130 is arranged along a first direction and spaced apart from the strain hanging plate 110; one end of the extension pull rod 120 is connected to the strain hanging plate 110, and the other end is connected to the positioning plate 130; each group of tensioning units includes a ring bolt 141, an alloy adjusting column 142, a connecting hanging plate 143 and a wedge-shaped clamp 144, one end of the ring bolt 141 is connected to the positioning plate 130, and the other end is connected to the alloy adjusting column 142; the connecting hanging plate 143 is configured with a first sliding groove 1431, when the alloy adjusting column 142 is in an unlocked position, the alloy adjusting column 142 can move along its own axial direction in the first sliding groove 1431, when the alloy adjusting column 142 is in a locked position, the first sliding groove 1431 limits the movement of the alloy adjusting column 142 along its own axial direction; one end of the connecting hanging plate 143 away from the alloy adjusting column 142 is connected to the wedge-shaped clamp 144.

[0036] The double-split conductor single-phase double-set wedge-type strain backup clamp device includes a strain hanging plate 110, an extension pull hook, a positioning plate 130, and two sets of tension units, each set of tension units corresponding to one conductor 1000, connected with the triangular connecting plate 300 through the strain hanging plate 110 to fix the device on the line; the conductor 1000 is fixed and supported by the wedge-shaped clamp 144 in the tension unit, ensuring the stability and safety of the conductor 1000 under high tension conditions and reducing the possibility of line sway; the connecting hanging plate 143 and the ring-shaped bolt 141 are locked by the alloy adjusting column in the locked position, ensuring the connection reliability between the components. When the conductor 1000 is fatigued and even broken, the tension unit will tightly hold the conductor 1000, and under the cooperation of the positioning plate 130 and the extension pull rod 120, the conductor 1000 will not directly fall to the ground, reducing the loss caused by the line breakage accident, improving the power supply reliability, and improving the social image and economic benefits of the power grid enterprise.

[0037] As shown in Figure 1 some embodiments, the strain hanging plate 110 is provided with three mounting holes, two of which are used to connect with the triangular connecting plate 300, and the other is used to connect the extension pull rod 120. By providing the strain hanging plate 110, not only the connection with the triangular connecting plate 300 on the line is achieved, but also a hanging point is provided for the wedge-shaped clamp 144.

[0038] As shown in Figure 3 some embodiments, when the alloy adjusting column 142 is in the unlocked position, that is, the length direction of the alloy adjusting column 142 is parallel to the extension direction of the first sliding groove 1431, so that the alloy adjusting column 142 can be inserted into the first sliding groove 1431 along the axial direction; after the threading is completed, the alloy adjusting column 142 is rotated by ninety degrees around the axial direction to reach the locked position, that is, the length direction of the alloy adjusting column 142 is perpendicular to the extension direction of the first sliding groove 1431, that is, the length of the alloy adjusting column 142 is smaller than the slot width of the first sliding groove 1431, so that the alloy adjusting column 142 is limited to be pulled out of the first sliding groove 1431, and the locking of the alloy adjusting column 142 and the connecting hanging plate 143 is achieved. At the same time, by rotating the alloy adjusting column 142 to the locked position, the friction direction can be changed, the vertical pre-tightening force can be increased, and the wear between the components can be reduced. Understandably, the extension direction is the length direction.

[0039] Referring to Figures 1 to 2As shown, in one embodiment, the extension direction of the connecting hanging plate 143 intersects with the extension direction of the annular bolt 141. The connecting hanging plate 143 and the annular bolt 141 are at an angle, which significantly avoids the contact and friction between the components and reduces the abrasion. In some embodiments, the extension direction of the connecting hanging plate 143 is at an angle with the extension direction of the conductor 1000, so that the contact and friction between the connecting hanging plate 143 and the conductor 1000 can also be avoided, the service life is prolonged, the risk of line drop or breakage is reduced, and the safety of the power transmission line is improved.

[0040] Referring to Figures 1 to 3 As shown, in one embodiment, the connecting hanging plate 143 includes two connecting plates 1432, which are respectively connected to the two ends of the alloy adjusting column 142 along the axial direction thereof. By arranging two separate connecting plates 1432, the connection of the connecting hanging plate 143 and the wedge-shaped wire clamp 144 can be facilitated, and the connection of the connecting hanging plate 143 and the annular bolt 141 can be facilitated. Among them, the two connecting plates 1432 are symmetrically arranged upward and downward, a first sliding groove 1431 is formed at one end of the connecting plate 1432 close to the positioning plate 130, and a mounting groove is formed at the other end of the connecting plate 1432 away from the positioning plate 130, and the connecting plate 1432 is fixed with the wedge-shaped wire clamp 144 through the mounting groove, that is, the front and rear ends of the connecting hanging plate 143 are both configured with a slot.

[0041] Referring to Figures 1 to 2 and Figure 4 As shown, in one embodiment, the wedge-shaped wire clamp 144 includes an outer shell 1441 and two wedge-shaped sliding blocks 1442, the outer shell 1441 is configured with two wedge-shaped grooves, each wedge-shaped sliding block 1442 is correspondingly clamped in the wedge-shaped groove, and the wedge-shaped sliding block 1442 is connected to the connecting hanging plate 143. In some embodiments, the wedge-shaped sliding block 1442 can be made of high-strength alloy steel or aluminum alloy, which has good tensile strength and corrosion resistance. Since the wedge-shaped sliding block 1442 can slide in the wedge-shaped sliding groove of the outer shell 1441, when subjected to external force, the wedge-shaped sliding block 1442 will be more tightly embedded in the conductor 1000, increasing the friction, so that the conductor 1000 can be firmly held, having a large gripping force and a large breaking load, and improving the fixing effect.

[0042] Referring to Figures 1 to 2 and Figure 5As shown, in one embodiment, the double-broken conductor single-phase double-sleeve wedge type strain backup clamp device includes a first right-angle hanging plate 150, one end of which is connected to the extension pull rod 120 and the other end of which is connected to the positioning plate 130. In some embodiments, the first right-angle hanging plate 150 can be made of high-strength alloy steel or stainless steel. In some embodiments, the first right-angle hanging plate 150 is configured with two first clamping grooves 151, one of which is used to clamp the extension pull rod 120 and the other of which is used to clamp the positioning plate 130, and the two first clamping grooves 151 are perpendicular to each other in the axial direction. In this way, the first right-angle hanging plate 150 can provide an angle conversion function, so that the conductor 1000 can be turned from one direction to another direction to adapt to different installation requirements and terrain conditions; and can provide reliable connection points in two perpendicular directions, so that the conductor 1000 can be supported and fixed in different directions, ensuring that it can maintain the correct tension and spacing under various environmental conditions, optimizing the tension distribution of the conductor 1000, reducing the stress concentration problem caused by irregular terrain, and improving the overall stability of the system.

[0043] Referring to Figures 1 to 2 and Figure 6 As shown, in one embodiment, the number of extension pull rods 120 is two, and a second right-angle hanging plate 160 is connected between the two extension pull rods 120. In some embodiments, the second right-angle hanging plate 160 can be made of high-strength alloy steel or stainless steel. In one embodiment, the second right-angle hanging plate 160 is configured with two second clamping grooves 161, which are correspondingly clamped with the two extension pull rods 120, and the two second clamping grooves 161 are perpendicular to each other in the axial direction. In this way, the second right-angle hanging plate 160 can provide reliable connection points in two perpendicular directions, so that the conductor 1000 can be supported and fixed in different directions, ensuring that it can maintain the correct tension and spacing under various environmental conditions.

[0044] Referring to Figures 1 to 2 and Figure 5As shown, in one of the embodiments, the tension unit further comprises a first hanging ring 145, one end of which is connected to the positioning plate 130, and the other end of which is connected to the annular bolt 141. In some embodiments, the first hanging ring 145 is a U-shaped hanging ring. By designing the U-shaped hanging ring, it is convenient for it to pass through the annular bolt 141. The two ends of the U-shaped hanging ring are provided with mounting holes, which are convenient for locking connection with the positioning plate 130. Due to the design of the U-shaped hanging ring, the installation angle and position of the conductor 1000 can be conveniently adjusted, and it is ensured that the conductor 1000 can maintain correct tension and spacing under various environmental conditions. At the same time, the U-shaped hanging ring can effectively disperse the mechanical load borne by the conductor 1000 and transmit it to the supporting structure, avoiding damage caused by local stress concentration; it can also help maintain the balance of the conductor 1000 and prevent swinging or vibration caused by external factors such as wind and ice and snow.

[0045] Referring to Figure 1 As shown, in one of the embodiments, the double-bundle conductor single-phase double-wedge type tension backup clamp device further comprises a second hanging ring 170, one end of which is connected to the positioning plate 130, and the other end of which is connected to the conductor line. Among them, the positioning plate 130 is configured with a first connecting hole, and the positioning plate 130 is connected to the first hanging ring 145 through the first connecting hole; the positioning plate 130 is configured with a second connecting hole spaced from the first connecting hole, and the positioning plate 130 is connected to the second hanging ring 170 through the second connecting hole. It can be understood that the second connecting hole is located outside the first connecting hole. In some embodiments, the positioning plate 130 is a rectangular hanging plate, and the first connecting hole and the second connecting hole can be round holes. For example, in the embodiment shown, the number of round holes is five, the first bolt passes through the middle round hole to connect the positioning plate 130 with the first right-angle hanging plate 150, that is, with the extension tension rod 120, the second bolt passes through the first connecting hole outside the middle round hole to connect the positioning plate 130 with the first hanging ring 145, and the third bolt passes through the second connecting hole outside the first connecting hole to connect the second tension ring with the positioning plate 130. In this way, the positioning plate 130 serves as an intermediate connecting piece to connect the annular bolt 141 connected with the wedge-shaped clamp 144 with the tension hanging plate 110 and determines the connection position. Figure 1 As shown, in one of the embodiments, the double-bundle conductor single-phase double-wedge type tension backup clamp device further comprises a second hanging ring 170, one end of which is connected to the positioning plate 130, and the other end of which is connected to the conductor line. Among them, the positioning plate 130 is configured with a first connecting hole, and the positioning plate 130 is connected to the first hanging ring 145 through the first connecting hole; the positioning plate 130 is configured with a second connecting hole spaced from the first connecting hole, and the positioning plate 130 is connected to the second hanging ring 170 through the second connecting hole. It can be understood that the second connecting hole is located outside the first connecting hole. In some embodiments, the positioning plate 130 is a rectangular hanging plate, and the first connecting hole and the second connecting hole can be round holes. For example, in the embodiment shown, the number of round holes is five, the first bolt passes through the middle round hole to connect the positioning plate 130 with the first right-angle hanging plate 150, that is, with the extension tension rod 120, the second bolt passes through the first connecting hole outside the middle round hole to connect the positioning plate 130 with the first hanging ring 145, and the third bolt passes through the second connecting hole outside the first connecting hole to connect the second tension ring with the positioning plate 130. In this way, the positioning plate 130 serves as an intermediate connecting piece to connect the annular bolt 141 connected with the wedge-shaped clamp 144 with the tension hanging plate 110 and determines the connection position.

[0046] Among them, the extension direction of the first hanging ring 145 and the extension direction of the second hanging ring 170 intersect. Through the staggered and superimposed design of the first hanging ring 145 and the second hanging ring 170, the installation angle and position of the conductor 1000 can be conveniently adjusted while fixing the positioning plate 130, and it is ensured that the conductor 1000 can maintain correct tension and spacing under various environmental conditions, avoiding damage caused by stress and shear stress.
