Abstract
Description
Technical Field
[0001] This utility model relates to the field of fixed support technology, specifically a 35kV cable fixing support for the base of a wind turbine tower. Background Technology
[0002] The base area of the wind turbine tower serves as a key node connecting the nacelle and the foundation, undertaking multiple functions such as cable transmission, mechanical support, and environmental protection. The 35kV cable, as the core power transmission medium from the base of the tower to the substation, directly affects the safe operation and power generation efficiency of the unit, hence the installation of cable fixing brackets.
[0003] For example, patent publication number "CN220797707U", entitled "Cable Fixing Bracket for Wind Turbine Generator", includes a frame body. An adjustable clamp is provided at the top of the frame body, and a support frame is provided on the frame body below the adjustable clamp. The support frame is vertically adjustable and mounted on the frame body. A tightening device is also provided at the top of the frame body. The aforementioned utility model's cable fixing bracket for wind turbine generators can support the cable and ensure the stability of the cable and equipment connection.
[0004] The above-mentioned method of fixing the cable by "passing the upper end of the cable through the installation ring 401" is not easy to operate during the passing process because the cable used for wind turbine generators is large in size. The cable used for wind turbine generators is usually a 35kV cable with an outer diameter of about 110-115mm. At the same time, the cable used for wind turbine generators is too long and needs to be moved a long distance during the passing process. Combined with its size, the installation process is quite inconvenient. Therefore, a 35kV cable fixing bracket at the bottom of the wind turbine generator tower is proposed. Utility Model Content
[0005] The purpose of this utility model is to provide a 35kV cable fixing bracket at the base of a wind turbine tower to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a 35kV cable fixing bracket at the base of a wind turbine tower, comprising a base, a support rod fixedly connected to the top of the base, a crossbar fixedly connected to the top of the support rod, and a connecting component fixedly connected to one side of the crossbar;
[0007] The connecting assembly includes a fixing member, which is fixedly installed on one side of the crossbar. A connecting rod is installed inside the fixing member. A limiting member is fixedly connected to one end of the connecting rod. A fixing plate is fixedly connected to one end of the connecting rod. A gasket is installed between the outer wall of the connecting rod and one side of the fixing plate. A clamping member is slidably connected to the outer wall of the connecting rod. A limiting assembly is installed between the limiting member and the fixing member.
[0008] Preferably, the limiting component includes a pad, which is installed between the limiting member and the fixing member, and a positioning device is fixedly connected between the pad and the fixing member.
[0009] Preferably, the positioning device includes a positioning bolt rod, and the bottom end of the positioning bolt rod is threaded through the fixing member and connected to a No. 1 nut.
[0010] Preferably, the bottom end of the fixing member has a through hole, and the bottom end of the positioning bolt rod passes through the fixing member through the through hole.
[0011] Preferably, the fixing member has an arc-shaped hole on one side, and the limiting member passes through the arc-shaped hole to one side of the fixing member.
[0012] Preferably, the top of the base is fixedly connected to a corner piece, and the top of the corner piece is fixed to one side of the support rod.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] The 35kV cable fixing bracket at the base of the wind turbine tower uses a connecting component to allow the cable to be placed on one side of the fixing component during use. The connecting rod on the clamping component then passes through the arc hole, and the clamping component is fixed in position by the limiting component. This method eliminates the need for the cable to pass through the gap between the fixing component and the clamping component; the cable can be moved, making the cable installation process simple.
[0015] Meanwhile, the fixing component is fixed by passing through an arc hole at one end of the limiting component and the connecting rod, and a pad is installed between the fixing component and the limiting component. The pad and the fixing component are precisely fixed by the combination of the positioning bolt rod and the No. 1 nut. This structure applies force to the limiting component through the pad, which is transmitted to the clamping component through the connecting rod. This makes the clamping component exert a stable force on the cable, effectively solving the problem of the cable sagging due to its own weight and ensuring the reliability of the cable head installation.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] like Figure 1 - Figure 3 As shown, this utility model provides a technical solution: a 35kV cable fixing bracket at the base of a wind turbine tower, including a base 1, a support rod 2 fixedly connected to the top of the base 1, a crossbar 3 fixedly connected to the top of the support rod 2, and a connecting component 4 fixedly connected to one side of the crossbar 3.
[0022] The connecting component 4 includes a fixing member 401, which is fixedly installed on one side of the crossbar 3. A connecting rod 402 is installed inside the fixing member 401. A limiting member 403 is fixedly connected to one end of the connecting rod 402. A fixing plate 404 is fixedly connected to one end of the connecting rod 402. A gasket 405 is installed between the outer wall of the connecting rod 402 and one side of the fixing plate 404. A clamping member 406 is slidably connected to the outer wall of the connecting rod 402. A limiting component 5 is installed between the limiting member 403 and the fixing member 401.
[0023] The limiting component 5 includes a pad 501, which is installed between the limiting member 403 and the fixing member 401. A positioning device is fixedly connected between the pad 501 and the fixing member 401.
[0024] The positioning device includes a positioning bolt rod 502, the bottom end of which passes through the fixing member 401 and is threadedly connected to a nut 503.
[0025] The bottom end of the fastener 401 has a through hole, and the bottom end of the positioning bolt rod 502 passes through the fastener 401 through the through hole.
[0026] A circular arc hole is provided on one side of the fastener 401, and the limiting member 403 passes through the circular arc hole to one side of the fastener 401.
[0027] An angle piece 6 is fixedly connected to the top of the base 1, and the top of the angle piece 6 is fixed to one side of the support rod 2.
[0028] The 35kV cable is clamped by the clamping member 406 and the fixing member 401. During installation, the limiting member 403 and one end of the connecting rod 402 pass through the fixing member 401 through the arc hole. The positioning threaded rod and the first nut 503 fix the position between the pad 501 and the fixing member 401. By installing the pad 501, a force is applied to the limiting member 403 based on the presence of the pad 501. The force is transmitted through the connecting rod 402, so that the clamping member 406 applies a force to the cable. The pad 405 can diffuse the force area and protect the connecting rod 402. By adjusting the number of different pads 405, the pads 405 are located between the fixing plate 404 and the clamping member 406. The multiple pads 405 form a force distribution. The greater the thickness of the clamping element, the closer the distance between the clamping element 406 and the fixing element 401 will be during installation, thereby controlling the clamping force of the clamping element 406 on the cable. The fixing element 401 is penetrated by the arc hole through the limiting element 403 and the connecting rod 402. A pad 501 is installed between the fixing element 401 and the limiting element 403. The position of the pad 501 and the fixing element 401 is precisely fixed by the combination of the positioning bolt rod 502 and the first nut 503. This structure applies a force to the limiting element 403 through the pad 501, which is transmitted to the clamping element 406 through the connecting rod 402, so that the clamping element 406 forms a stable force on the cable, effectively solving the problem of the cable sagging due to its own weight and ensuring the reliability of the cable head installation.
[0029] The base 1, support rod 2, and corner piece 6 form a triangular structure, ensuring the stability of the bracket during use. The connecting rod 402 has two different diameters, and the gasket 501 has a notch. The connection between the connecting rod 402 and the gasket 501 is achieved through the fit between the notch and the smaller diameter position on the connecting rod 402, allowing adjustment of the number of gaskets 501. With the connecting component 4, the cable is placed on one side of the fixing member 401, allowing the connecting rod 402 on the clamping member 406 to pass through the arc hole. The clamping member 406 is then fixed in place by the limiting component 5, thus enabling cable installation. This method eliminates the need for the cable to pass through the gap between the fixing member 401 and the clamping member 406; simply moving the cable simplifies the installation process. The fixed bracket provides a stable clamp, preventing cable loosening and poor contact, ensuring the stability of power transmission, reducing the risk of short circuits and open circuits, and optimizing the tower base space layout for convenient daily inspection and maintenance.
[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended embodiments and their equivalents.
