Description

Technical Field

[0001] The utility model relates to the technical field of cable fixing, in particular to a cable fixing device for a lattice tower. Background Technique

[0002] With the enlargement of wind turbines, the height of the tower also increases. To balance the contradiction between the contribution of the high tower to the power generation of the unit and the increase in its own cost, on the one hand, it is necessary to meet the requirements for the performance of the tower as a support structure, and on the other hand, new tower technologies are continuously developed. The steel cylinder-lattice combined tower (referred to as the lattice tower) as a new type of tower form meets the development of large-scale units.

[0003] However, the lattice tower also has some difficulties to be solved due to its own structural form. Among them, the structural form of the lattice section will expose the cable to the air, accelerating the damage of the cable and causing the normal operation of the unit. Therefore, it is necessary to use a cable trough box to protect the cable.

[0004] For example, the Chinese patent with the patent number 201320422249.2 provides a cable trough box, which is suitable for being fixed at any position such as the side wall and the top plate. The opening of the trough box is arranged on one side in the horizontal direction, facilitating wiring and future maintenance and repair work. At the same time, the cover body is hinged to the trough body, which is more convenient and fast during the installation process, saving a lot of time and reducing the working intensity of workers.

[0005] However, the existing lattice cable fixing device for wind turbines is not convenient for sorting the fixed cables, resulting in the cables being scattered in the fixing device, affecting its heat dissipation effect, and also having a certain impact on the service life of the cables and the normal operation of the unit. Summary of the Utility Model

Those skilled in the art can make some non-essential improvements and adjustments to the present invention based on the above application content.

[0032] Embodiment:

[0033] As Figure 1 ,2 As shown in the figure, the present utility model provides a cable fixing device for a lattice tower, which includes a trough box. The trough box includes a top cover 101, two groups of side plates 102 and a bottom plate 103. The two groups of side plates 102 are respectively vertically arranged at both ends of the top cover 101 and are fixedly connected thereto by bolts. The two ends of the bottom plate 103 are respectively fixedly connected to the two groups of side plates 102 by bolts.

[0034] When in use, the top cover 101, the two groups of side plates 102 and the bottom plate 103 are connected by bolts to form the trough box body, and multiple groups of trough boxes can be spliced and fixed according to the required length. Moreover, the materials of the top cover 101 and the bottom plate 103 are different from that of the side plates 102. In some preferred embodiments, the top cover 101 and the bottom plate 103 are made of steel plates, and the side plates 102 are made of aluminum alloy to prevent the cable from generating eddy current effect. And a louver 104 is arranged on the bottom plate 103. During assembly, first assemble the top cover 101 and the two groups of side plates 102, and then assemble the bottom plate 103 with the louver 104. The inside of the trough box is dissipated heat through the louver 104. When the temperature is too high, the bottom plate 103 can also be disassembled to improve the heat dissipation effect.

[0035] As Figure 2 、 3 shown, in this embodiment, multiple groups of clamping blocks 201 are arranged side by side in the trough box. Grooves 202 are formed on the sides of the multiple groups of clamping blocks 201. The grooves 202 on every two adjacent groups of clamping blocks 201 form a cavity for the cable to pass through. A fixing component connected to the multiple groups of clamping blocks 201 is arranged on the trough box. The positions of the multiple groups of clamping blocks 201 are fixed through the fixing component, and the multiple groups of clamping blocks 201 are driven to close. The fixing component includes a threaded rod 401. The threaded rod 401 penetrates through one side of the trough box and the multiple groups of clamping blocks 201. A first fastening nut 402 is screwed at one end of the threaded rod 401. The first fastening nut 402 is in contact with the trough box. A second fastening nut 403 with the same number of groups as the clamping blocks 201 is also screwed on the threaded rod 401. The multiple groups of second fastening nuts 403 are respectively in contact with the multiple groups of clamping blocks 201.

[0036] The cable can be placed in two relatively arranged grooves 202, and then the multiple groups of second fastening nuts 403 are tightened so that the multiple groups of clamping blocks 201 close. And the appropriate number of clamping blocks 201 can be selected for assembly and use according to the number of cables, thereby facilitating the arrangement and fixing of different numbers of cables, avoiding the cable winding from affecting the heat dissipation effect, and at the same time preventing the cables from colliding with each other in the trough box, thereby effectively improving the service life of the cables.

[0037] As Figure 3As shown, in this embodiment, a binding assembly is provided on one set of clamping blocks 201. The binding assembly includes a receiving plate 203 provided on one side of one set of clamping blocks 201. A binding plate 301 is provided on one side of the receiving plate 203. A bending portion 302 is provided on the binding plate 301. A cavity for a cable tie to pass through is formed between the bending portion 302 and the receiving plate 203. Multiple sets of binding holes 303 are formed in the bending portion 302. One set of second fastening nuts 403 is in contact with the binding plate 301.

[0038] The binding plate 301 is detachably arranged, so that it is convenient to selectively install the binding plate 301 for use according to the actual situation. When there are some small-diameter cables, the grooves 202 are not convenient for fixing the cables. Then, the cable tie can be passed through the binding holes 303 and the small-diameter cables can be fixed, thereby improving the practicability of the device.

[0039] The specific usage method and beneficial effects of the present utility model:

[0040] When the device is in use, multiple sets of trough boxes can be assembled end to end through bolts according to the length of the cable to be fixed. During the use process, the cable is placed in the trough box to protect the cable through the trough box. Moreover, the larger-diameter cables can be placed in two sets of oppositely arranged grooves 202, and then the multiple sets of clamping blocks 201 are controlled to close and fix through the fixing assembly to fix the multiple sets of cables. The smaller-diameter cables can also be tied to one side of one set of clamping blocks 201 through the cooperation of the binding assembly and the cable tie, so as to facilitate the arrangement of various cables, effectively prevent the cables from winding in the trough box, and improve the heat dissipation effect of the cables.

[0041] The above shows and describes the basic principles, main features and advantages of the present utility model. For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments. Based on the present utility model, some modifications or improvements can be made, which are obvious to those skilled in the art. Therefore, these modifications or improvements made without departing from the spirit of the present utility model all fall within the scope of protection required by the present utility model.
