Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of photovoltaic panel installation, in particular to a photovoltaic cable locking device. BACKGROUND

[0002] When installing a photovoltaic panel, a flexible photovoltaic support is often used. The flexible photovoltaic support uses a steel strand as a main bearing cable (main cable), and the main cable is fixed by an end support formed by a steel beam and an edge anchor. Since the main cable has a long span, a plurality of support steel frames are arranged in the middle to form a middle support so that the main cable passes through and is supported. The cross beam node of the middle support not only needs to be able to lock and fix the main cable, but also needs to be able to slide the main cable to facilitate the adjustment of the main cable. Therefore, the present application provides a photovoltaic cable locking device. CONTENT OF THE UTILITY MODEL

[0003] The present application provides a photovoltaic cable locking device which can lock and slide the main cable.

[0004] The technical scheme of the present application is as follows:

[0005] The present application provides a photovoltaic cable locking device, which comprises a base and a sliding block.

[0006] The base has a receiving cavity, and the bottom of the receiving cavity is provided with a first clamping groove extending along the axial direction of the main cable. The top of the base is screwed with a positioning rod extending into the receiving cavity.

[0007] The sliding block is slidingly clamped in the receiving cavity, and the sliding block has a second clamping groove corresponding to the first clamping groove. The top of the sliding block is provided with a positioning groove.

[0008] The inner end of the positioning rod abuts against the groove bottom of the positioning groove, and the rotation of the positioning rod can push the sliding block to move towards the inside of the receiving cavity.

[0009] According to the technical scheme of the present application, the rotation of the positioning rod pushes the sliding block to move towards the inside of the receiving cavity, so that the main cable can be locked between the first clamping groove and the second clamping groove. The rotation of the positioning rod can reduce the clamping force of the sliding block on the main cable, thereby facilitating the adjustment of the main cable.

[0028] In the related art, flexible photovoltaic supports are often used when installing photovoltaic panels, the flexible photovoltaic support uses a steel strand as a main bearing cable (main cable), the main cable is then fixed by an end support formed by a steel beam and an edge anchor, since the main cable has a long span, a plurality of support steel frames are arranged in the middle to form a middle support, so that the main cable passes through and is supported. The cross beam node of the middle support not only needs to be able to lock and fix the main cable, but also needs to be able to slide the main cable to facilitate the adjustment of the main cable.

[0029] The embodiment provides a photovoltaic cable locking device which can lock and slide a main cable.

[0030] Please refer to Figs. 1-2 In the embodiment, the photovoltaic cable locking device comprises a base 10 and a sliding block 20; the base 10 has a receiving cavity 11, the bottom of the receiving cavity 11 is provided with a first clamping groove 12 extending along the axial direction of a main cable 40, and the top of the base 10 is screwed with a positioning rod 14 extending into the receiving cavity 11; the sliding block 20 is slidingly clamped in the receiving cavity 11, the sliding block 20 is provided with a second clamping groove 21 corresponding to the first clamping groove 12, and the top of the sliding block 20 is provided with a positioning groove 22; the inner end of the positioning rod 14 abuts against the groove bottom of the positioning groove 22, and the screwing of the positioning rod 14 can push the sliding block 20 to move towards the inside of the receiving cavity 11.

[0031] According to the technical scheme, the screwing of the positioning rod 14 pushes the sliding block 20 to move towards the inside of the receiving cavity 11, the main cable 40 can be locked between the first clamping groove 12 and the second clamping groove 21, the unscrewing of the positioning rod 14 can reduce the clamping force of the sliding block 20 on the main cable 40, and the adjustment of the main cable 40 is facilitated.

[0032] In the embodiment, the base 10 is integrally formed in a rectangular block shape, the base 10 is welded to the upper surface of a cross beam 30, the receiving cavity 11 is a rectangular cavity structure formed on the base 10, the receiving cavity 11 penetrates through one side wall of the base 10 facing away from the end face of the cross beam 30, the first clamping groove 12 is arranged at the cavity bottom of the receiving cavity 11, and the first clamping groove 12 is formed in an arc shape matched with the shape of the main cable 40, the first clamping groove 12 extends along the axial direction of the main cable 40 and penetrates through the left and right side walls of the base 10, and the avoiding opening 13 is arranged on the side wall of the receiving cavity 11, i.e., the left and right side walls of the base 10, and the avoiding opening 13 is connected with the first clamping groove 12.

[0033] It should be noted that the extension direction of the receiving cavity 11 is parallel to the longitudinal direction of the cross beam 30, the axial direction of the main cable 40 is perpendicular to the longitudinal direction of the cross beam 30, i.e., the extension direction of the receiving cavity 11 is perpendicular to the extension direction of the first clamping groove 12, and the extension direction of the avoiding opening 13 is parallel to the extension direction of the receiving cavity 11, i.e., the extension direction of the avoiding opening 13 is perpendicular to the extension direction of the first clamping groove 12.

[0034] In the embodiment, the adjusting rod 14 is screwed on the top of the base 10, the inner end of the adjusting rod 14 extends into the inside of the receiving cavity 11, and the adjusting rod 14 is perpendicular to the extension direction of the first clamping groove 12 and the extension direction of the receiving cavity 11.

[0035] In the embodiment, the slider 20 is integrally configured in a rectangular block shape, and the slider 20 is clamped in the receiving cavity 11 in a shape-fitting manner. The lower surface of the slider 20 is attached to the upper surface of the cross beam 30, the upper surface and the left and right surfaces of the slider 20 are attached to the three inner side walls of the receiving cavity 11, the second clamping groove 21 is arranged on the surface of the slider 20 opposite to the first clamping groove 12, the second clamping groove 21 is configured as an arc-shaped groove matching the shape of the main cable 40, and the second clamping groove 21 extends along the axial direction of the main cable 40. The second clamping groove 21 cooperates with the first clamping groove 12 to lock the main cable 40.

[0036] In addition, the positioning groove 22 is arranged on the upper surface of the slider 20, the extension direction of the positioning groove 22 is parallel to the extension direction of the receiving cavity 11, the positioning groove 22 is arranged corresponding to the positioning rod 14, and the depth of the positioning groove 22 increases away from the second clamping groove 21.

[0037] It should be noted that the main cable 40 is moved into the first clamping groove 12 through the avoiding opening 13. After the slider 20 is placed in the receiving cavity 11, the positioning rod 14 is screwed into the receiving cavity 11, and the inner end of the positioning rod 14 abuts against the groove bottom of the positioning groove 22. Since the groove bottom of the positioning groove 22 is designed as a slope structure, the pushing action of the positioning rod 14 will push the slider 20 into the receiving cavity 11, that is, the second clamping groove 21 is close to the first clamping groove 12, until the main cable 40 is locked between the first clamping groove 12 and the second clamping groove 14.

[0038] When it is necessary to pull the adjustment main cable 40, the positioning rod 14 is screwed out a certain distance. At this time, the slider 20 has a moving space to the outside of the receiving cavity 11, that is, the clamping force of the slider 20 on the main cable 40 is reduced, and the main cable 40 can be pulled and adjusted.
