Technical Field

[0001] The utility model relates to the technical field of solar photovoltaic assembly installation, in particular to a device for downwardly installing a roof photovoltaic cable fixing assembly bolt. Background Art

[0002] The existing solar photovoltaic module installation bracket has a relatively small span, so many columns and other components are needed when laying photovoltaic modules, a large amount of steel is used, and the installation is complicated and time-consuming. As a result, a method of installing the solar panels above the ropes by setting up poles and setting ropes on the top of the poles has been developed.

[0003] However, when this installation method is used on a roof with a certain slope or a bumpy surface, it is necessary to measure and prefabricate the poles in advance so that the tops of the poles on the front or rear sides are at the same horizontal height, so that the solar panels above the ropes have a good condition to be exposed to the sun. This method takes a certain amount of time to prepare materials and needs to prepare the poles according to the installation site. Therefore, a device for installing the roof photovoltaic cable fixing assembly from top to bottom with bolts is proposed to solve the above problem. Utility Model Content

It solves the problem that when this installation method is used on a roof with a certain inclination or a bumpy surface, it is necessary to measure and prefabricate the poles in advance to make the tops of the poles on the front or rear side at the same horizontal height. This method takes a certain amount of time to prepare materials and needs to prepare the poles according to the installation site.

[0006] (II) Technical solution

[0007] The utility model solves the above-mentioned technical problems with a technical solution as follows: a device for bolt-down installation on a roof photovoltaic cable fixing assembly, comprising a base, a photovoltaic cable and a solar panel, the base being distributed on the roof surface at four corners, the top of the base being fixedly connected with a sleeve, the interior of the sleeve being slidably connected with a lifting screw rod extending above it, the top of the sleeve being fixedly connected with an assembly ring located on the outside of the lifting screw rod, the assembly ring being provided with a lifting and regulating device which is rotatably connected to the top of the sleeve and threadably connected to the lifting screw rod and extending to the front side thereof, photovoltaic cables fixedly connected to the roof surface are provided between the lifting screw rods on the front and rear sides, and solar panels distributed laterally equidistantly are provided above the photovoltaic cables.

[0008] The beneficial effects of the utility model are:

[0009] The device is installed downward on the bolts of the roof photovoltaic cable fixing assembly. When it is installed on a roof surface with a certain inclination or a pothole surface, the lifting and lowering screw rod can be slid up and down in the sleeve through the lifting and lowering control device, so that the top of the lifting and lowering screw rod located on the front side or the rear side is at the same horizontal height, and then photovoltaic cables fixedly connected to the roof surface are provided between the front and rear lifting and lowering screw rods, so that the solar panel can be installed above the photovoltaic cables, which has the advantages of good adaptability and no need to prefabricate the rack poles in advance according to the installation site.

[0010] On the basis of the above technical solution, the present invention can also be improved as follows.

[0011] Furthermore, the lifting and lowering control device includes a worm gear rotating ring, a worm and a hexagonal bolt rod. The top of the sleeve is rotatably connected to the worm gear rotating ring located in the assembly ring.

The inside of the assembly ring is rotatably connected to a worm meshing with the worm gear rotating ring. The front side of the worm is fixedly connected to a hexagonal bolt rod extending to the front side of the assembly ring.

[0012] The beneficial effect of adopting the above further scheme is that the hexagonal bolt head rod is rotated by an electric wrench or an hexagonal wrench, which in turn drives the worm to rotate. Since the worm is meshed with the worm gear rotating ring, the worm gear rotating ring is driven to rotate on the outside of the lifting screw. Since the worm gear rotating ring is threadedly connected to the lifting screw, and the lifting screw is slidably connected to the sleeve, the lifting screw can slide up and down in the sleeve.

[0013] Furthermore, the outer side of the lifting screw rod near the top thereof is provided with a rope threading hole, and a pulley adapted to the photovoltaic cable is rotatably connected in the rope threading hole.

[0014] The beneficial effect of adopting the above further scheme is that the photovoltaic cable is installed between the front and rear lifting screw rods, the photovoltaic cable passes through the rope threading hole and is located on the outside of the pulley, and the two ends of the photovoltaic cable are fixed on the roof surface. When the solar panel shakes due to air flow disturbance, the pulley can protect the photovoltaic cable to avoid direct contact between the photovoltaic cable and the lifting screw rod and thus cause wear.

[0015] Furthermore, the top of the base is provided with circular holes distributed in a circular array.

[0016] The beneficial effect of adopting the above further solution is that the circular hole is used to fix the base so that the bolt passes through the circular hole, and then the base is fixed to the roof surface.

[0017] Furthermore, a slider located in the sleeve and slidably connected to the sleeve is fixedly connected to the bottom of the lifting screw rod.

[0018] The beneficial effect of adopting the above further solution is that when the lifting screw rod slides up and down in the sleeve, the slider plays a guiding role. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] In the embodiment, Figure 1-5 Provided is a device for installing a roof photovoltaic cable fixing assembly from above by bolts, the utility model comprises a base 1, a photovoltaic cable 2 and a solar panel 3, the base 1 is distributed on a roof surface 4 at four corners, the top of the base 1 is fixedly connected with a sleeve 5, the interior of the sleeve 5 is slidably connected with a lifting screw 6 extending to the top thereof, the top of the sleeve 5 is fixedly connected with an assembly ring 7 located on the outside of the lifting screw 6, the assembly ring 7 is provided with a lifting and regulating device 8 which is rotatably connected to the top of the sleeve 5 and is threadedly connected to the lifting screw 6 and extends to the front side thereof, photovoltaic cables 2 fixedly connected to the roof surface 4 are provided between the lifting screws 6 on the front and rear sides, and solar panels 3 distributed laterally equidistantly are provided above the photovoltaic cables 2;

[0027] The lifting and lowering control device 8 includes a worm gear rotating ring 801, a worm 802 and a hexagon socket bolt rod 803. The top of the sleeve 5 is rotatably connected to the worm gear rotating ring 801 located in the assembly ring 7. The worm gear rotating ring 801 is located on the outside of the lifting screw 6 and is threadedly connected to the lifting screw 6. The inside of the assembly ring 7 is rotatably connected to the worm 802 meshing with the worm gear rotating ring 801. The front side of the worm 802 is fixedly connected to the hexagon socket bolt rod 803 extending to the front side of the assembly ring 7.

[0028] The hexagon socket bolt rod 803 is rotated by an electric wrench or an hexagon socket wrench, which in turn drives the worm 802 to rotate. Since the worm 802 is meshed with the worm gear rotating ring 801, the worm gear rotating ring 801 is driven to rotate outside the lifting screw 6. Since the worm gear rotating ring 801 is threadedly connected to the lifting screw 6, and the lifting screw 6 is slidably connected to the sleeve 5, the lifting screw 6 can slide up and down in the sleeve 5.

[0029] The outer side of the lifting screw rod 6 near the top thereof is provided with a rope threading hole 9, and the rope threading hole 9 is rotatably connected with a pulley 10 adapted to the photovoltaic cable 2;

[0030] The photovoltaic cable 2 is installed between the front and rear lifting screw rods 6. The photovoltaic cable 2 passes through the rope threading hole 9 and is located outside the pulley 10. Both ends of the photovoltaic cable 2 are fixed to the roof surface 4. When the solar panel 3 shakes due to air flow disturbance, the pulley 10 can protect the photovoltaic cable 2 to prevent the photovoltaic cable 2 from directly contacting the lifting screw rod 6 and causing wear.

[0031] The top of the base 1 is provided with circular holes 11 distributed in a circular array;

[0032] The circular hole 11 is used to fix the base 1 so that the bolt passes through the circular hole 11, and then the base 1 is fixed to the roof surface 4;

[0033] The bottom of the lifting screw rod 6 is fixedly connected with a slider 12 located in the sleeve 5 and slidably connected with the sleeve 5;

[0034] When the lifting screw rod 6 slides up and down in the sleeve 5, the slider 12 plays a guiding role.

[0035] Working principle:

[0036] Step 1: When the device is installed on a roof surface 4 or a pitted ground surface with a certain inclination, the device is fixed to the roof surface 4 or the pitted ground surface in a four-corner distribution form;

[0037] Step 2: Use an electric wrench or an inner hexagonal wrench to rotate the inner hexagonal bolt rod 803, which in turn drives the worm 802 to rotate. Since the worm 802 is meshed with the worm gear rotating ring 801, the worm gear rotating ring 801 is driven to rotate outside the lifting screw 6. Since the worm gear rotating ring 801 is threadedly connected to the lifting screw 6, and the lifting screw 6 is slidably connected to the sleeve 5, the lifting screw 6 can slide up and down in the sleeve 5, and the height of the top of the lifting screw 6 is adjusted in turn, so that the top of the lifting screw 6 located at the front side or the rear side is at the same level.

[0038] Step 3: The photovoltaic cable 2 is installed between the front and rear lifting screw rods 6. The photovoltaic cable 2 passes through the rope threading hole 9 and is located outside the pulley 10. Both ends of the photovoltaic cable 2 are fixed on the roof surface 4. When the solar panel 3 shakes due to air flow disturbance, the pulley 10 can protect the photovoltaic cable 2 to avoid direct contact between the photovoltaic cable 2 and the lifting screw rod 6 and wear, thereby installing the solar panel 3 above the photovoltaic cable 2.
