Description

Technical Field

[0001] The invention relates to the technical field of power transmission line maintenance, and in particular to an ice adhesion strength testing device suitable for a conductor. Background Art

[0002] Conductor ice adhesion test is a test method to evaluate the impact of ice and snow on power lines in cold weather conditions. The main purpose of this test is to simulate and measure the adhesion of ice and snow on the conductors, and then understand its impact on the performance and safety of power lines.

[0003] Transmission line icing refers to the accumulation of ice on the lines, which increases the load on the lines. This can cause the lines to deform, bend, or even break, leading to large-scale power outages. At the same time, icing may also damage transmission towers and other power facilities, increasing the cost of repair and replacement. In addition, the increase in ice will also reduce the electrical performance of the wires and increase the risk of failure in the power system. In order to ensure the stability and safety of the power system, protective measures need to be taken on the transmission lines to reduce the harm caused by icing.

[0004] There are some problems in the use of existing conductor ice coating simulation and ice adhesion strength measurement devices. First, the simulation conditions in the laboratory may not be able to fully replicate the complex climatic conditions in the actual environment, resulting in deviations between the test results and the actual situation. Secondly, the ice adhesion strength test equipment may not perform consistently with different types of ice layers, affecting the accuracy of the measurement. In addition, the installation and maintenance costs of the field monitoring system are high, and sensor failures may occur under extreme weather conditions. Finally, testing different types of conductors requires frequent disassembly and assembly of the fixing clips, which is cumbersome to operate, and different types of conductors have different curvatures, making it impossible to flexibly adjust the clamping points to make the curvature of the conductor more in line with the actual environment and improve the accuracy of the test results.

[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0033] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0034] Example 1

[0035] Reference Figure 1 , which is the first embodiment of the present invention, provides an ice adhesion strength testing device suitable for a conductor, which includes a supporting unit 100, including a base 101, a supporting frame 102, an adjusting rail 103 and a load-bearing frame 104, the supporting frame 102 is symmetrically fixed on the top of the base 101, the two ends of the adjusting rail 103 are respectively fixed to the top of the supporting frames 102 on both sides, the load-bearing frame 104 is arranged parallel to the adjusting rail 103, and the two ends thereof are respectively movably connected to the supporting frames 102 on both sides.

[0036] Among them, the support unit 100 is made of metal material as a whole, the base 101 is placed horizontally on the experimental operating table, the support frame 102 is symmetrically fixed above the two ends of the base 101, and a top adjustment rail 103 is vertically arranged to support it to ensure that it is in a horizontal state. The two ends of the load-bearing frame 104 are slidably inserted into the inside of the support frame 102, and can be moved up and down to adjust the height.

[0037] The testing unit 200 includes a cooling table 201, an ice mold 202 and a bonding strength detector 203. The cooling table 201 is fixed at the bottom of the load-bearing frame 104, the ice mold 202 is movably installed at the top of the load-bearing frame 104, and the bonding strength detector 203 is detachably fixed at the top of the load-bearing frame 104.

[0038] The cooling platform 201 preferably adopts a semiconductor cooling platform, which can quickly cool the water or other mixed liquid in the top ice mold 202 and turn it into ice cubes.

[0039] Among them, the ice mold 202 is made of polytetrafluoroethylene as a whole, which can reduce the adhesion between ice and the mold, help demolding, and avoid excessive adhesion between ice cubes and the mold, which makes demolding inconvenient.

[0040] Furthermore, the bonding strength tester 203 preferably adopts the LR-6000C integrated bonding strength tester, which drives the central stretching part to move by shaking the rocker on the side wall of the instrument, and quickly measures the traction force when the ice cube is separated from the wire.

[0041] Furthermore, during use, the bonding strength tester 203 does not need to be installed and fixed immediately. At this time, the ice mold 202 needs to be placed above the load-bearing frame 104, and the cooling table 201 is turned on. The ice mold 202 is in contact with the cooling surface of the cooling table 201, and the wire is immersed in the ice mold 202. After a period of time, the liquid in the ice mold 202 condenses and adheres to the wire.

[0042] Furthermore, the load-bearing frame 104 is adjusted to descend, and the ice cube and the ice mold 202 fall off naturally. At this time, the ice mold 202 is quickly taken out, and the bonding strength tester 203 is installed so that it is engaged with the hook under the ice cube. The side wall rocker of the bonding strength tester 203 is further shaken, and the central stretching part of the bonding strength tester 203 is pulled downward until the ice cube is separated from the wire. At this time, the bonding strength tester 203 can record and display the instantaneous tension when the ice cube is separated, so that researchers can study and compare.

[0043] The fixing unit 300 includes a width adjusting fixture 301 and a tightening fixture 302 . The width adjusting fixture 301 is symmetrically and movably mounted on the adjusting rail 103 , and the tightening fixture 302 is movably mounted on the top of the width adjusting fixture 301 .

[0044] Furthermore, before starting the test, it is necessary to insert the required test wire between the width adjustment clamp 301 and the tightening clamp 302, and then control the tightening clamp 302 to move and clamp the wire.

[0045] Furthermore, if the curvature of the wire needs to be adjusted, the distance between the width adjustment fixtures 301 is controlled so that the wire is stretched toward both ends or relaxed toward the middle to change the curvature of the wire.

[0046] Example 2

[0047] Reference Figure 1 to Figure 5, which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the width adjustment fixture 301 includes a trapezoidal adjustment block 301a, a vertical plate 301b, a plug-in plate 301c and a first clamping plate 301d, the vertical plate 301b is symmetrically fixed on both sides of the trapezoidal adjustment block 301a, the plug-in plate 301c is symmetrically fixed on the bottom of the trapezoidal adjustment block 301a, and the first clamping plate 301d is fixedly connected to the bottom of the plug-in plate 301c.

[0048] Limiting plates 301b-1 are symmetrically fixed at both ends of the vertical plate 301b away from the trapezoidal adjustment block 301a, and a sliding rod 301b-1a is fixed between the limiting plates 301b-1. The sliding rod 301b-1a is outer-connected with a first spring T1, and the first spring T1 is fixed to the limiting plate 301b-1 close to the trapezoidal adjustment block 301a.

[0049] The cross section of the trapezoidal adjustment block 301a is a right-angled trapezoidal structure, which includes an upper end surface M1, a lower end surface M2, an inclined end surface M3 and a vertical surface M4. The upper end surface M1 is the top edge of the right-angled trapezoid, and the lower end surface M2 is the bottom edge of the right-angled trapezoid.

[0050] Among them, the vertical plate 301b is preferably a long plate-like structure, symmetrically arranged on the side walls of the trapezoidal adjustment block 301a adjacent to the inclined end surface M3, and the limiting plates 301b-1 are preferably arranged in four pieces, all of which are plate-like structures and vertically arranged at both ends of the vertical plate 301b.

[0051] A connecting sleeve 301a-1 is also fixed on the lower end surface M2, and a first threaded hole 301a-1a is also opened in the connecting sleeve 301a-1, and the connecting sleeve 301a-1 is located between the plug-in boards 301c; at least one group of inclined calipers 301a-2 are equidistantly fixed on the inclined end surface M3, and abutment slides 301a-3 are formed on the inclined end surface M3 between the inclined calipers 301a-2 and the vertical plates 301b on both sides. The abutment slides 301a-3 are rectangular groove structures, and the groove walls on both sides are the side walls of the vertical plates 301b and the inclined calipers 301a-2.

[0052] Among them, the oblique caliper 301a-2 is made of metal material, which can ensure that it will not break when engaged, thereby ensuring the stability of the connection.

[0053] The tightening clamp 302 includes a top plate 302a, an inverted trapezoidal block 302b, a stabilizing connecting plate 302c and a second clamping plate 302d. The inverted trapezoidal block 302b is fixedly connected to the bottom of the top plate 302a, the stabilizing connecting plate 302c is symmetrically fixed to the bottom of the top plate 302a and is located on both sides of the inverted trapezoidal block 302b, and both ends of the second clamping plate 302d are fixed to the stabilizing connecting plate 302c. The second clamping plate 302d can be installed at the lower end of the stabilizing connecting plate 302c by bolt fixing, which is convenient for disassembly and assembly.

[0054] A straight slot 302c-1 is formed on the stabilizing connecting plate 302c, and the sliding rod 301b-1a is slidably inserted into the straight slot 302c-1, and the first spring T1 is movably abutted against the side wall of the stabilizing connecting plate 302c.

[0055] The cross section of the inverted trapezoidal block 302b is an inverted right-angled trapezoidal structure, the bottom end surface of the inverted trapezoidal block 302b is a load-bearing surface M5, and its oblique waist is a contact surface M6.

[0056] A built-in groove 302b-1 is horizontally opened in the inverted trapezoidal block 302b, and a connecting groove 302b-2 is also opened on the contact surface M6, and the connecting groove 302b-2 divides the contact surface M6 into symmetrical pressure walls 302b-3, and the pressure walls 302b-3 are slidably inserted into the abutment slide 301a-3, and the oblique caliper 301a-2 can be inserted into the connecting groove 302b-2; a limiting hole 302a-1 is also opened in the top plate 302a, and the limiting hole 302a-1 is connected to the built-in groove 302b-1.

[0057] During use, in the initial state, the distance between the second clamping plate 302d and the first clamping plate 301d is the largest. At this time, the load-bearing surface M5 is placed above the plug-in board 301c, and the lower bottom surface of the top plate 302a is in contact with the upper end surface M1.

[0058] Furthermore, at this time, the top plate 302a is pushed horizontally, and the pressing wall 302b-3 moves obliquely along the abutting slideway 301a-3, so that the tightening clamp 302 is lifted horizontally as a whole, and at the same time, the second clamping plate 302d clamps the internal wire toward the first clamping plate 301d.

[0059] Furthermore, during this process, the slide bar 301b-1a moves in the straight slot 302c-1, and the stabilizing link plate 302c squeezes the first spring T1, causing it to contract and tighten.

[0060] It should be noted that a metal cap may be connected to the contact surface between the first spring T1 and the stabilizing connecting plate 302c to ensure that the stabilizing connecting plate 302c pushes the first spring T1 horizontally and prevent the first spring T1 from scratching the stabilizing connecting plate 302c.

[0061] A connecting piece 302b-4 is also slidably inserted in the inverted trapezoidal block 302b. The connecting piece 302b-4 includes a control plate 302b-4a and a push plate 302b-4b and a stabilizing plate 302b-4c respectively fixed on the top and bottom thereof. A bevel tooth plate 302b-4d is also fixed on one end of the stabilizing plate 302b-4c.

[0062] The control plate 302b-4a and the stabilizing plug plate 302b-4c are slidably inserted into the limiting hole 302a-1 and the built-in groove 302b-1 respectively, and a second spring T2 is fixed between the stabilizing plug plate 302b-4c and the inner wall of the built-in groove 302b-1 on a side away from the connecting groove 302b-2. The bevel tooth plate 302b-4d is matched and placed in the connecting groove 302b-2, and at least one group of fixed bevel teeth 302b-4d1 are arranged and fixed on the side of the bevel tooth plate 302b-4d away from the stabilizing plug plate 302b-4c, and the fixed bevel teeth 302b-4d1 are movably engaged with the bevel caliper 301a-2.

[0063] Reference Figure 5 During use, as the tightening clamp 302 slides obliquely upward, the outer inclined surface of the fixed oblique tooth 302b-4d1 slides relatively with the outer inclined surface of the oblique caliper 301a-2, causing the connecting member 302b-4 to move to the left, the second spring T2 is squeezed and contracted, and the top plate wall of the oblique tooth plate 302b-4d fits against the inner wall of the connecting groove 302b-2.

[0064] Furthermore, when the tightening clamp 302 rises to a position where it can clamp the wire, the top plate 302a is released. At this time, the tightening clamp 302 has a tendency to move downward under its own gravity, and the fixed bevel tooth 302b-4d1 is no longer subjected to thrust, and the second spring T2 is reset, so that the fixed bevel tooth 302b-4d1 can be inserted between the bevel caliper 301a-2, completing the locking of the bevel tooth plate 302b-4d and the bevel caliper 301a-2, that is, completing the work of the tightening clamp 302 and the width adjusting clamp 301 in cooperating to clamp the wire.

[0065] It should be noted that the wire clamping only needs to ensure that the wire will not come off if pulled by a small external force. It does not need to be clamped too tightly to damage the wire surface and affect subsequent testing.

[0066] If you want to adjust the position of the wire, you need to unlock the tightening clamp 302 and the width adjusting clamp 301. First, further clamp the wire so that the tightening clamp 302 is slightly lifted. You only need to fix the bevel tooth 302b-4d1 to slide out from between the tooth grooves of the bevel caliper 301a-2. At this time, you need to push the pushing plate 302b-4b to the left so that the top plate wall of the bevel tooth plate 302b-4d is re-fitted with the inner wall of the connecting groove 302b-2, and the fixed bevel tooth 302b-4d1 is completely separated from the bevel caliper 301a-2.

[0067] Furthermore, the tightening clamp 302 is no longer limited by the inclined caliper 301a-2, and the pressure wall 302b-3 slides down along the abutment slide 301a-3. The first spring T1 will reset and push the stabilizing connecting plate 302c to assist in unlocking. The second clamping plate 302d contacts the first clamping plate 301d to clamp the wire, and then the wire clamping position can be adjusted.

[0068] The remaining structures are the same as those of Example 1.

[0069] Example 3

[0070] Reference Figures 1 to 8 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that a sliding slot 102a is provided on the side where the two side support frames 102 are close to each other, the load-bearing frame 104 includes a pressure-bearing frame 104a and transverse plates 104b symmetrically connected at both ends thereof, the transverse plates 104b are slidably inserted into the sliding slot 102a, the cooling platform 201 is detachably fixed to the bottom of the pressure-bearing frame 104a, and a through hole 201a is provided in the middle of the cooling platform 201.

[0071] The transverse plate 104b is a long plate-shaped structure, the pressure-bearing frame 104a is a rectangular frame, and the transverse plate 104b is fixed on the width side wall of the pressure-bearing frame 104a.

[0072] Furthermore, the cooling stage 201 is preferably a semiconductor cooling stage in the prior art, which is fixed to the bottom of the pressure frame 104 a by auxiliary mounting connections such as bolts, and can move up and down with the load-bearing frame 104 .

[0073] An ice groove 202a is provided on the ice mold 202, and wire release grooves 202b are also provided on both side ends thereof. A hook hole 202c is provided in the middle of the bottom of the ice groove 202a, and a connecting hook 202d is slidably installed in the hook hole 202c. A placement plate 202e is horizontally fixed to the bottom of the two side walls of the ice mold 202 adjacent to the wire release groove 202b, and the placement plate 202e is placed on the pressure frame 104a.

[0074] Among them, the ice groove 202a is a rectangular groove, and the wire release groove 202b is an arc groove, which is opened at the upper position of both ends of the ice mold 202. During use, the wire is placed horizontally in the ice groove 202a and passes through the wire release groove 202b, so that the wire is in full contact with water.

[0075] Furthermore, the cooling table 201 is turned on, and the water at the bottom of the ice mold 202 gradually condenses into ice. According to the real-time freezing situation, the researchers can add small amounts of water into the ice mold 202 frequently to simulate a more realistic wire icing situation.

[0076] Furthermore, the connecting hook 202d is placed and installed in the hook hole 202c. A sealing plug is also connected to the connecting hook 202d. The hook hole 202c is a rectangular hole. The sealing plug can seal the hook hole 202c to prevent water in the ice groove 202a from leaking out of the hook hole 202c. The rectangular structure of the hook hole 202c also facilitates the connection part of the lower connecting hook 202d to move upward and disengage from the hook hole 202c.

[0077] Furthermore, during the condensation process of the water in the ice groove 202a, the connecting hook 202d is always placed in the through hole 201a.

[0078] It should be noted that the ice mold 202 is made of polytetrafluoroethylene. When demolding is required, the staff can slightly push the connecting hook 202d from below the through hole 201a to push the ice cube upward with the wire, and quickly complete the demolding.

[0079] The top connection end 203a of the bonding strength tester 203 is displaced in the vertical direction, and the two ends of the bottom of the bonding strength tester 203 are fixed with fixed feet 203b, and the fixed feet 203b are detachably fixed to the pressure frame 104a.

[0080] The bonding strength tester 203 preferably adopts the LR-6000C integrated bonding strength tester, which can control the central stretching part to pull the ice cubes and measure the stretching force by shaking the operating lever.

[0081] The adjusting rail 103 is symmetrically provided with an adjusting hole 103a and an adapting hole 103b, and the adapting hole 103b is located on both sides of the adjusting hole 103a.

[0082] The first adjusting rod 103c is rotatably inserted into the adjusting hole 103a, the plug-in plate 301c and the connecting sleeve 301a-1 are slidably inserted into the adapting hole 103b and the adjusting hole 103a respectively, and the first adjusting rod 103c is threadedly inserted into the first threaded hole 301a-1a.

[0083] One end of the first adjusting rod 103c extending out of the adjusting rail 103 is also fixed with a rotating handle 103c-1; the second adjusting rod 101a is symmetrically rotated and inserted into the top of the base 101, and the second adjusting rod 101a is threadedly inserted into the horizontal plate 104b.

[0084] At the beginning of the test, it is first necessary to clamp the wire according to the operating process of the above embodiment, and then confirm the bending curvature of the wire. After determining the bending curvature, turn the handle 103c-1 to control the rotation of the first adjustment rod 103c. Under the action of the thread, the first adjustment rod 103c drives the connecting sleeve 301a-1 to move.

[0085] Furthermore, according to the required curvature, the tension of the wire is adjusted. After the curvature of the wire is adjusted, the second adjustment rod 101a is rotated to control the load-bearing frame 104 to move upward, so that the ice mold 202 moves to the bottom of the wire, and then the icing and ice covering operations are completed.

[0086] Furthermore, after the icing work is completed and the mold is demolded successfully, the second adjusting rod 101a is rotated in the opposite direction to control the load-bearing frame 104 to move downward, so that the ice mold 202 is separated from the ice cube, and then the ice mold 202 is removed, and the bonding strength tester 203 is installed. After the bottom hook of the bonding strength tester 203 is connected to the connecting hook 202d, the bonding strength tester 203 is started, the rocker of the bonding strength tester 203 is rotated, and the connecting hook 202d is pulled downward until the ice cube is separated from the wire.

[0087] Furthermore, at the moment when the ice cube is separated from the wire, the bonding strength detector 203 will automatically record the traction force value, and the researchers can measure it multiple times until the research needs are met.

[0088] The remaining structure is the same as that of Example 2.
