Description

TECHNICAL FIELD

[0001] The utility model belongs to cable laying technical field relates to a cable fixing device for slope section. BACKGROUND

[0002] In recent years, the installed capacity of new energy has been rapidly increasing. With the increasing number of photovoltaic power stations year by year, the land resources in areas with good construction conditions such as sufficient sunlight and flat terrain are gradually decreasing. The construction of photovoltaic power stations in areas with secondary construction conditions such as agriculture, animal husbandry, lakes, and mountains has become a priority for the construction of photovoltaic power stations, among which, the mountain photovoltaic power station with complex terrain and topography is the most prominent. Cable laying and installation in mountain photovoltaic power stations is a key link in construction quality. The cable is an important power transmission line connecting photovoltaic modules and inverters, inverters and box transformers, and box transformers and switch stations. The rationality and effectiveness of the laying scheme play a crucial role in the operation stability and power generation efficiency of the photovoltaic power generation system.

[0003] In conventional ground photovoltaic power stations, the terrain is flat, and the geology changes little. The cable is mostly laid in a straight-buried or pipe-laid manner. In mountainous complex terrain and water photovoltaic power stations, due to the complex and variable terrain, geology, topography, and hydrology, the cable is mostly laid in the slope section, with an inclination angle of 20 to 50 degrees. When the cable is laid, a large self-weight tension will be generated. The photovoltaic direct-current cable has no armored layer and cannot withstand a large self-weight tension. Long-term stress will damage the cable structure and cause cable grounding faults and other problems. In mountainous slopes, soil erosion often occurs. If the cable is not fixed, it will be impacted and cause cable displacement, which may even lead to cable breakage and affect the power generation of photovoltaic modules. SUMMARY

[0004] NOVEL CONTENT

[0005] The utility model aims at providing a cable fixing device for slope section, which solves the problem that the existing cable laid in a straight-buried or bridge-laid manner in a slope terrain is easily impacted by water and soil erosion, causing cable displacement, which may even lead to cable breakage and affect the power generation of photovoltaic modules.

[0006] The utility model adopts the technical scheme of a cable fixing device for slope section, which comprises a bracket and a hoop for passing through the cable. The bracket comprises vertically opposite support rods and a crossbeam arranged between the support rods. The inner concave surface of the hoop faces the crossbeam and is fixed.

[0007] Further, the inner surface of the hoop is provided with a rubber insulating pad.

[0008] Further, the hoop is a semicircular hoop.

[0009] Further, the support rod is an angle steel, and the cross beam is a steel plate.

[0010] Further, the cross beam is horizontally fixed to the top of the support rod.

[0011] Further, the cross beam and the hoop are fixed through a nut and a screw rod.

[0012] The cable fixing device for the slope section has the advantages that: when the device is used, the support rod of the support structure is vertically embedded into the slope, and the cable is fixed between the hoop and the cross beam of the support structure, so that even if the soil and water loss occurs on the slope, the possibility of displacement is greatly reduced, the problem of broken cable caused by serious soil and water loss is avoided, and the problem of affecting the power generation of the photovoltaic module is solved.

[0019] An embodiment of a cable fixing device for sloping terrain includes a bracket 1 and a clamp 7 for passing a cable 5 through it, such as... Figure 1 As shown, the support 1 includes a pair of vertically opposite support rods at a certain distance and a crossbeam between the two support rods. In this embodiment, the support rods are made of angle steel, and the crossbeam is made of U-shaped steel plate with an opening facing downwards. The two ends of the steel plate serving as the crossbeam are fixed to the top of the angle steel on both sides. The clamp 7 is a semi-circular cable clamp and is fixed to the top of the steel plate. The concave surface of the semi-circular cable clamp 7 faces the steel plate serving as the crossbeam. In this embodiment, the angle steel on both sides of the support 1 is vertically opposite to each other and is used to be buried vertically downwards into the slope.

[0020] In other embodiments, the two ends of the steel plate can be horizontally fixed to the non-top position of the two side angle steels, or inclinedly fixed to any position of the two side angle steels, with the concave surface of the clamp 7 still facing the steel plate for fixing.

[0021] The semi-circular cable clamp 7 has openings at both ends, such as... Figure 2 As shown, the steel plate of the bracket 1 is also provided with a corresponding hole diameter that is adapted to the opening of the semi-circular cable clamp 7. The screw 4 passes through the opening of the semi-circular cable clamp 7 and the hole diameter that is adapted to the angle steel bracket in sequence and is fixed by the nut 2. The nut 2 is also provided with a bolt washer 3 facing the steel plate.

[0022] A rubber insulating pad 6 is also provided on the inner surface of the semi-circular cable clamp 7.

[0023] In other embodiments, the bracket 1 may also be a fiberglass bracket.

[0024] In other embodiments, the semi-circular cable clamp 7 can also be located below the steel plate, in which case the concave surface of the semi-circular cable clamp 7 is also fixed facing the steel plate.

[0025] The specific installation method in this embodiment is as follows:

[0026] Firstly, excavate the cable trench in the slope section, clean the stones and foreign matters in the trench, and then embed the angle steel support after cleaning. The angle steel support is embedded vertically to the slope, the height of the support exposed to the ground is measured, and the cable is laid after meeting the design requirements. The cable is placed on the support, and the cable is checked after laying. After ensuring that the cable is not subjected to external force, the cable is wrapped with rubber insulation pad, and the cable is fixed firmly with semi-circular cable clamp. After acceptance, backfilling is carried out.

[0027] The device of the embodiment is simple to manufacture and convenient to install. After fixing, the self-weight tension of the cable can be greatly reduced, and no pollutants are generated during the construction process. In the case of water and soil loss on the slope, the displacement of the cable can be avoided, and the influence on the power generation of the photovoltaic module is prevented. In addition, compared with the bridge laying, the construction cost is effectively reduced, and the installation speed is improved.
