Description

Technical Field

[0001] This utility model relates to the field of wind power generation technology, and in particular to a suspension hardware string and wind tower structure. Background Technology

[0002] In high-voltage and ultra-high-voltage transmission line projects, suspension hardware strings play a crucial role in connecting conductors to straight-line towers and achieving suspension. The core conductor fixing component of the widely adopted suspension hardware string structure is the suspension clamp. This clamp mechanically grips the conductor to transmit force and position it. However, existing suspension clamp designs have significant limitations when dealing with the extreme and complex load environments of heavy icing areas: insufficient clamping capacity; the inherent structural design and clamping force of the suspension clamp may not be sufficient to overcome the enormous vertical load on the conductor under conditions of thick ice cover and rapidly increasing ice load in heavy icing areas; and there is a risk of conductor slippage and detachment. On the one hand, conductor detachment may damage nearby equipment, cause forest fires, and threaten the safety of repair personnel, seriously endangering power grid operation safety and public safety. On the other hand, it will cause power outages, involving not only high emergency repair costs but also huge losses of electricity. Utility Model Content

The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] The following is combined Figure 1 This invention describes a suspension hardware string and wind tower structure provided by an embodiment of the present invention. It should be understood that the following description is merely an illustrative embodiment of the present invention and does not constitute any particular limitation on the present invention.

[0027] An embodiment of the first aspect of this utility model provides a suspension hardware string, such as Figure 1 As shown, it includes: an insulator 100; a connecting plate, one end of which is connected to the insulator 100; a wire clamp 300, which is connected to the other end of the connecting plate and is used to connect a conductor; and an auxiliary connecting assembly 400, one end of which is used to connect to the conductor and the other end of which is connected to the connecting plate.

[0028] The suspension hardware string provided by this utility model includes an insulator 100, a connecting plate, a wire clamp 300, and an auxiliary connecting assembly 400. One end of the connecting plate is connected to the insulator 100, and the other end is connected to the wire clamp 300. The wire clamp 300 is used to clamp the connecting conductor. One end of the auxiliary connecting assembly 400 is connected to the conductor, and the other end is connected to the connecting plate. Thus, the wire clamp 300 and the auxiliary connecting assembly 400 together clamp the connecting conductor. This improves the clamping strength of the conductor, which not only enhances the safety of wind tower structure operations but also prevents power outages caused by conductor detachment, thereby reducing repair costs and power loss costs.

[0029] In one embodiment of this utility model, the auxiliary connection component 400 includes: a plate, which is connected to a connecting hanging plate; and a connecting rope, one end of which is connected to the plate and the other end of which is used to connect to a wire.

[0030] Furthermore, in one embodiment of this utility model, the connecting rope includes a twisted wire rope 450, one end of which is connected to the plate, and the other end of which is twisted to connect with the conductor. The twisted wire rope 450 is made of high-strength, high-toughness alloy wire, which is tightly wound around the conductor through a special processing technology, providing strong grip and effectively preventing the conductor from slipping. The design of the twisted wire rope 450 increases the contact area and friction with the conductor, ensuring that the conductor can be firmly fixed even under heavy ice loads.

[0031] In one embodiment of this utility model, the suspension hardware string further includes: a tower hanging plate 600, which is used to connect to the tower of the wind tower; and a ball head hanging ring 700, one end of which is connected to the tower hanging plate 600, and the other end of which is connected to the insulator 100.

[0032] For example, such as Figure 1 As shown, the conductor is fixed by two suspension hardware strings. Specifically, taking one of the suspension hardware strings as an example, the tower mounting plate 600 is stably connected to the tower through a corresponding installation structure, providing a reliable suspension foundation for the entire suspension hardware string and ensuring that it can withstand the weight of the suspension hardware string and the conductor, as well as the tensile force generated by heavy ice loads. One end of the ball-head ring 700 is precisely connected to the tower mounting plate 600, and the other end of the ball-head ring 700 is connected to the upper end of the insulator 100. The ball-head structure of the ball-head ring 700 allows the insulator 100 to rotate flexibly within a certain range, effectively alleviating stress concentration caused by external forces such as conductor swaying, wind, and heavy ice, and protecting the insulator 100 and other connecting components.

[0033] The lower end of the insulator 100 is connected to the connecting plate, which in turn is connected to the clamp 300. The clamp 300 is used to hold the conductor. A plate is also connected to the connecting plate. One end of the stranded rope 450 is connected to the plate, and the other end is twisted and connected to the conductor. The stranded rope 450, the connecting plate, the clamp 300, and the conductor segment located between the stranded rope 450 and the clamp 300 can collectively form a triangular structure.

[0034] In one embodiment of this utility model, the connecting plate includes: a first hanging plate 210, one end of which is connected to the insulator 100 and the other end of which is connected to the plate; and a second hanging plate 220, one end of which is connected to the plate and the other end of which is connected to the wire clamp 300.

[0035] Furthermore, in one embodiment of this utility model, the plate includes: an adjustment plate 410, which is connected between the first hanging plate 210 and the second hanging plate 220. The adjustment plate 410 is provided with a plurality of connecting holes at intervals, and a connecting rope is connected to a certain connecting hole to adjust the tension of the connecting rope.

[0036] like Figure 1 As shown, the connecting plate comprises two parts: a first mounting plate 210 and a second mounting plate 220. The first mounting plate 210 is connected to the lower end of the insulator 100, and the second mounting plate 220 is connected to the wire clamp 300. An adjusting plate 410 is connected between the first mounting plate 210 and the second mounting plate 220. The adjusting plate 410 has multiple connecting holes spaced apart, for example... Figure 1 As shown, the adjusting plate 410 has an arc-shaped structure with multiple connecting holes spaced apart on its arc-shaped edge. Therefore, the connecting rope can be connected to different connecting holes to change the tension of the connecting rope according to actual working conditions.

[0037] In one embodiment of the present invention, the plate further includes an intermediate connector, through which the connecting rope is connected to a connecting hole of the adjusting plate 410.

[0038] Furthermore, in one embodiment of this utility model, the intermediate connecting member includes: a first connecting plate 420 disposed on one side of the adjusting plate 410; a second connecting plate disposed on the other side of the adjusting plate 410; the first connecting plate 420 and the second connecting plate being correspondingly disposed; a first connecting bolt 430 passing through and connecting between the first connecting plate 420, a certain connecting hole, and the second connecting plate; a second connecting bolt 440 passing through and connecting between the first connecting plate 420 and the second connecting plate, and the second connecting bolt 440 being located at the end away from the adjusting plate 410; one end of a twisted wire rope 450 being twisted and connected to a wire, and the other end of the twisted wire rope 450 being sleeved and connected to the second connecting bolt 440.

[0039] like Figure 1As shown, a first connecting plate 420 and a second connecting plate are respectively attached to both sides of the adjusting plate 410. A first connecting bolt 430 passes through a connecting hole on the first connecting plate 420, the adjusting plate 410, and the second connecting plate in sequence to fix the three together. A second connecting bolt 440 is provided at the end of the first connecting plate 420 and the second connecting plate away from the first connecting bolt 430. One end of the twisted wire rope 450 is twisted and connected to the guide, and the other end extends obliquely close to the position of the first connecting plate 420 and the second connecting plate, and is sleeved on the second connecting bolt 440. That is to say, the twisted wire rope 450 can be connected to the adjusting plate 410 through the intermediate connecting member. When it is necessary to adjust the tension of the twisted wire rope 450, it is only necessary to adjust the connection position of the intermediate connecting member on the adjusting plate 410, which makes the adjustment operation relatively convenient.

[0040] In one embodiment of the present invention, the wire clamp 300 includes: a U-shaped bracket 310 for supporting wires; a cover plate 320 connected to a second hanging plate 220, the cover plate 320 covering the opening of the U-shaped bracket 310; and a fastener 330 connected between the cover plate 320 and the U-shaped bracket 310.

[0041] The suspension hardware string also includes: a protective line 500, which is used to attach to the conductor and at least covers the conductor in the support section of the U-shaped bracket 310.

[0042] The wire clamp 300 is installed near the conductor joint end of the stranded rope 450. It works in conjunction with the stranded rope 450 to enhance the support and fixation of the conductor. The protective strip 500 is wrapped around the contact area between the conductor and the wire clamp 300. It is made of wear-resistant and high-strength material to enhance the conductor's abrasion resistance and extend its service life.

[0043] In the actual installation process, the tower mounting plate 600 is first precisely installed on the tower according to the design requirements. Then, the ball head ring 700 is installed on the tower mounting plate 600, and the installation direction is adjusted to ensure that the ball head ring 700 rotates flexibly. Next, the upper end of the insulator 100 is connected to the ball head ring 700, using a reliable connection method to ensure a tight connection.

[0044] Install the first mounting plate 210 at the lower end of the insulator 100, ensuring a secure connection between the first mounting plate 210 and the insulator 100 without any looseness. Connect the adjusting plate 410 to the lower end of the first mounting plate 210, and connect the second mounting plate 220 to the lower end of the first adjusting plate 410. Based on the actual conditions in the heavy icing area, select appropriate connecting holes on the adjusting plate 410 and connect them using the corresponding intermediate connecting wire rope 450. The first connecting plate 420 and the second connecting plate in the intermediate connecting parts are connected parallel to the adjusting plate 410, ensuring that the first connecting bolt 430 and the second connecting bolt 440 are securely connected.

[0045] Slide the twisted wire rope 450 onto the second connecting bolt 440 and twist it to the conductor. Strictly follow the installation requirements of the twisted wire rope 450 and tightly wrap it around the conductor. During the winding process, ensure that the pre-twisted wires are evenly distributed and closely adhered to the conductor to provide sufficient holding force.

[0046] Install the clamp 300 at a suitable position near the stranded wire 450, and precisely adjust the position of the suspension clamp 300 to effectively assist in fixing the conductor. Finally, wrap the protective cable 500 around the contact area between the conductor and the suspension clamp 300. After installation, conduct a thorough inspection of all connections to ensure that the connections are firm, reliable, and free from looseness.

[0047] As described in the above embodiments, the suspension hardware string consists of an adjustment plate 410, an intermediate connector, and a stranded wire rope 450, forming a reinforced spare clamp 300, thus optimizing the structure and stress distribution of the suspension hardware string. The adjustable function of the adjustment plate 410 allows the suspension hardware string to adapt to the complex and variable working conditions in heavy icing areas, precisely adjusting the length and angle of the stranded wire rope 450 to optimize stress distribution and reduce stress concentration. The stranded wire rope 450 and the clamp 300 work together to greatly enhance the holding force on the conductor, effectively preventing the conductor from slipping and falling off under heavy icing loads. This significantly improves the overall load-bearing capacity and stability of the suspension hardware string in heavy icing areas, ensuring the safe and reliable operation of transmission lines in heavy icing environments and reducing line maintenance costs and power outage risks. Compared with traditional suspension hardware strings, under the same heavy icing load, the conductor slippage rate of this suspension hardware string is reduced by 90%, and the damage rate of the hardware string clamp 300 is reduced by 90%, effectively improving the reliability and safety of the transmission line.

[0048] A second aspect of this utility model provides a wind tower structure, including the suspension hardware string as described above.

[0049] Furthermore, the wind tower structure provided by this utility model, since it includes the suspension hardware string as described above, also possesses the advantages described above.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
