Description

Technical Field

[0001] This utility model relates to the field of photovoltaic construction technology, and more specifically, to a tilt angle measuring device for photovoltaic construction. Background Technology

[0002] Photovoltaic construction refers to the process of installing and building a solar photovoltaic power generation system. When installing photovoltaic panels, in order to ensure the light absorption efficiency of the photovoltaic panels, it is generally necessary to adjust the tilt angle of the photovoltaic panels relative to the ground.

[0003] However, during photovoltaic panel installation, the uneven or tilted ground often affects the installers' ability to accurately determine the panel's tilt angle relative to the ground. Current measuring tools, such as common angle gauges and other manual measuring equipment, cannot measure the panel's tilt angle without a ground reference. Therefore, a novel tilt angle measuring device for photovoltaic installation is needed to address this problem. Utility Model Content

[0004] In view of this, this utility model proposes a tilt angle measuring device for photovoltaic construction to solve the problem of angle measurement when installing photovoltaic panels on tilted or uneven working surfaces.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A tilt angle measuring device for photovoltaic (PV) installation includes a measuring device body and a clamping plate assembly connected to one side of the measuring device body via a connecting rod. During installation, the upper and lower clamping plates of the clamping plate assembly are respectively attached to the top and bottom surfaces of the PV panel to be measured, and the axial direction of the connecting rod is consistent with the tilt direction of the PV panel. The measuring device body includes an installation chamber, which is a hollow cylinder. The front side of the installation chamber is a circular flat cover plate, and the rear side is a circular flat bottom plate. The curved outer wall on the left or right side is fixed to the connecting rod. The curved outer wall below and on the sides of the installation chamber has circumferentially arc-shaped grooves, and a groove is provided inside the installation chamber. The upper end of the swing rod is rotatably connected to the center of the inner wall of the flat base plate, and the lower end of the swing rod passes downward through the arc-shaped groove and is fixedly connected to the counterweight on the outside of the mounting compartment. The swing rod can swing along the arc-shaped groove. A scale groove concentric with the arc-shaped groove is opened on the flat cover plate. A pointing block fixed to the swing rod passes forward through the scale groove, and the pointing block can swing along the scale groove. When the measuring device is installed on a photovoltaic panel that is kept horizontal, the pointing block points to the 0 mark of the scale groove. When the measuring device is installed on the photovoltaic panel to be measured, the angle of the scale groove pointed to by the pointing block is consistent with the angle between the photovoltaic panel and the ground.

[0007] Preferably, the flat bottom plate and the curved outer wall are integrally connected to form the main body of the installation compartment. The upper side of the flat cover plate is connected to an upwardly protruding limiting block, and the upper side of the curved outer wall is connected to an installation plate. The limiting block can fit tightly against the installation plate. A limiting bolt is installed to the front side of the main body by passing through the bolt holes on the limiting block and the installation plate respectively.

[0008] Preferably, the curved outer wall is further provided with a limiting edge for positioning the flat cover plate on the front side of the main compartment.

[0009] Preferably, a gripping part is installed at the upper end of the mounting plate.

[0010] Preferably, a rotating rod is installed at the center of the inner wall of the flat base plate, and a raised edge is fixed on the rear side of the outer periphery of the rotating rod. A square hole is opened at the upper end of the swing rod, and the front end of the rotating rod includes a square head for passing through the square hole. A threaded rod is also connected to the front side of the square head, and a limiting nut is screwed onto the threaded rod to limit and fix the swing rod to the rotating rod.

[0011] Preferably, the rotating rod is connected to the inner wall of the flat base plate via a bearing.

[0012] Preferably, a magnetic sheet for adsorbing onto the photovoltaic panel mounting bracket is installed on the outer wall of the planar base plate.

[0013] Preferably, the counterweight is made of insulating material.

[0014] Preferably, the clamping plate assembly includes a guide chamber that is perpendicularly fixed to the connecting rod. Inside the guide chamber, a bidirectional lead screw is rotatably mounted, which is aligned with the direction of the lead screw's axis. The upper clamping plate is fixed to the outside of a lead screw nut installed on the upper side of the bidirectional lead screw, and the lower clamping plate is fixed to the outside of a lead screw nut installed on the lower side of the bidirectional lead screw. Rotating the bidirectional lead screw enables the corresponding upper and lower clamping plates to move synchronously in opposite directions or in opposite directions.

[0015] Preferably, one end of the bidirectional lead screw extends out of the guide chamber and is fixedly connected to a rotating handle.

[0016] Compared with existing technologies, the tilt angle measuring device for photovoltaic construction of this utility model has the following advantages:

[0017] (1) This utility model clamps the photovoltaic panel by having the upper and lower clamps in the clamping plate assembly work together. The installation chamber is placed outside the outer wall of the photovoltaic panel, and the axis of the connecting rod is aligned with the tilt direction of the photovoltaic panel to be tested. At this time, under the action of gravity, the swing rod points to the vertical ground. At this time, the pointing reading of the pointing block in the scale groove is consistent with the angle between the photovoltaic panel and the ground. The staff can intuitively obtain the angle of the photovoltaic panel based on the reading, thereby achieving efficient control of the angle between the photovoltaic panel and the ground.

[0018] (2) The operator can unscrew the limit bolt, remove the flat cover plate, and then rotate the limit nut to remove the swing rod, thereby disassembling and replacing the swing rod. At the same time, the rotating rod is mounted to the inner wall of the flat base plate through common bearings, which makes the rotation of the rotating rod smoother, reduces friction, and improves the accuracy of measurement.

[0019] (3) During installation, the entire device can be temporarily attached to the photovoltaic panel support using magnetic plates, and then the upper and lower clamping plates can be adjusted to clamp the photovoltaic panel. The magnetic plates prevent workers from having to carry the entire device by hand during installation, thus reducing their workload.

[0020] (4) The operator only needs to turn the handle to make the upper and lower clamps move synchronously towards each other or away from each other, which is simple and convenient to operate. Attached Figure Description

[0030] Example:

[0031] See Figure 1-Figure 4 This embodiment provides a tilt angle measuring device for photovoltaic construction, including a measuring device body 1 and a clamping plate assembly 2 connected to one side of the measuring device body 1 by a connecting rod 3.

[0032] When the measuring device of this utility model is installed, the upper clamping plate 24 and the lower clamping plate 25 in the clamping plate assembly 2 are respectively attached to the top and bottom surfaces of the photovoltaic panel to be tested, the axis of the connecting rod 3 is consistent with the tilt direction of the photovoltaic panel to be tested, and the measuring device body 1 is located outside the side wall of the photovoltaic panel to be tested.

[0033] The measuring device body 1 includes a mounting chamber, which is a hollow cylinder. The front side of the mounting chamber is a circular flat cover plate 4, and the rear side is a circular flat bottom plate 5. The curved outer wall 6 on the left or right side is fixedly connected to the connecting rod 3. The curved outer wall 6 on the bottom and sides of the mounting chamber is provided with an arc groove 7 in the circumferential direction. The upper end of the swing rod 8 located inside the mounting chamber is rotatably connected to the center of the inner wall of the flat bottom plate 5. The lower end of the swing rod 8 passes downward through the arc groove 7 and is fixedly connected to the counterweight 9 located outside the mounting chamber. The counterweight 9 is made of insulating material. The swing rod 8 can swing along the arc groove 7. A scale groove 10 concentric with the arc groove 7 is provided on the flat cover plate 4. The pointing block 11 fixed to the swing rod 8 passes forward through the scale groove 10, and the pointing block 11 can swing along the scale groove 10.

[0034] When the measuring device is installed on a photovoltaic panel that is kept horizontal, the pointing block 11 points to the 0 mark of the scale groove 10. When the measuring device is installed on the photovoltaic panel to be tested, the pointing block 11 points to the scale number of the scale groove 10 and the angle between the photovoltaic panel and the ground is consistent.

[0035] This invention uses the upper and lower clamping plates in the clamping plate assembly to clamp the upper and lower sides of the photovoltaic panel. The installation chamber is located outside the outer wall of the photovoltaic panel, and the axis of the connecting rod is aligned with the tilt direction of the photovoltaic panel to be tested. At this time, under the action of gravity, the swing rod swings along the arc groove and always points perpendicular to the ground. At this time, the pointing reading of the pointing block in the scale groove is consistent with the angle between the photovoltaic panel and the ground. The operator can intuitively obtain the angle of the photovoltaic panel based on the reading, thereby achieving efficient control of the angle between the photovoltaic panel and the ground.

[0036] In a further specific embodiment, such as Figure 1 , 2 As shown, the flat bottom plate 5 and the curved outer wall 6 are integrally connected to form the main body of the installation compartment. The upper side of the flat cover plate 4 is connected to the upward protruding limiting block 12, and the upper side of the curved outer wall 6 is connected to the mounting plate 13. The limiting block 12 can fit tightly against the mounting plate 13. A limiting bolt 14 is installed on the front side of the main body by passing through the bolt holes on the limiting block 12 and the mounting plate 13 respectively.

[0037] Furthermore, the curved outer wall 6 is also provided with a limiting edge 15 for positioning the flat cover plate 4 on the front side of the main body.

[0038] When in use, the staff places the flat cover plate 4 into the curved outer wall 6 of the main compartment. The limiting edge 15 can limit the flat cover plate 4, and the initial assembly of the installation compartment is completed. Then, the limiting block 12 above the flat cover plate 4 is pressed against the mounting plate 13 on the upper side of the curved outer wall 6. The limiting bolt 14 is passed through the bolt holes on the limiting block 12 and the mounting plate 13 respectively, and the flat cover plate 4 can be firmly fixed to the front of the main compartment through the upper limiting.

[0039] Meanwhile, a gripping part 16 is also installed on the upper end of the mounting plate 13 to facilitate the staff to pick up the device of this utility model.

[0040] In a further specific embodiment, such as Figure 3 As shown, a rotating rod 17 is installed at the center of the inner wall of the flat base plate 5. A raised edge 18 is fixed on the rear side of the outer periphery of the rotating rod 17. A square hole is opened at the upper end of the swing rod 8. The front end of the rotating rod 17 includes a square head 19 for passing through the square hole. After the swing rod 8 is installed, it will abut against the raised edge 18 on the rear side. A threaded rod 20 is also connected to the front side of the square head 19. The limiting nut 21 is adapted to be screwed onto the threaded rod 20 to limit and fix the swing rod 8 to the rotating rod 17.

[0041] The above structural design allows workers to easily fix the swing rod 8 on the rotating rod 17 and disassemble the swing rod 8 by rotating the limiting nut 21, thus facilitating the maintenance and replacement of the swing rod 8.

[0042] Furthermore, the rotating rod 17 is connected to the inner wall of the flat base plate 5 through a bearing, which makes the rotation process of the rotating rod 17 smoother, reduces friction, and improves the accuracy of measurement.

[0043] In a further specific embodiment, a magnetic sheet 27 for adsorbing onto the photovoltaic panel mounting bracket is installed on the outer wall of the planar base plate 5.

[0044] During installation, workers can first temporarily attach the entire device to the photovoltaic panel bracket using the magnetic plate 27, and then adjust the movement of the upper clamp 24 and lower clamp 25 to clamp the photovoltaic panel. The magnetic plate 27 avoids the need for workers to carry the entire device by hand during installation, reducing their workload.

[0045] In a further specific embodiment, such as Figure 4 As shown, the clamping plate assembly 2 includes a guide chamber 22 that is perpendicularly fixed to the connecting rod 3. A bidirectional lead screw 23 with the same axial direction as the guide chamber 22 is rotatably installed inside the guide chamber 22. An upper clamping plate 24 is fixed to the outside of a lead screw nut 1 installed on the upper side of the bidirectional lead screw 23, and a lower clamping plate 25 is fixed to the outside of a lead screw nut 22 installed on the lower side of the bidirectional lead screw 23. Rotating the bidirectional lead screw 23 can enable the corresponding upper clamping plate 24 and lower clamping plate 25 to move synchronously towards or away from each other.

[0046] When in use, the staff needs to first set the upper and lower clamps on the upper and lower sides of the photovoltaic panel respectively, and then control the movement of the two clamps by driving the bidirectional lead screw 23 to make the two clamps work together to clamp the photovoltaic panel.

[0047] Furthermore, one end of the bidirectional lead screw 23 extends out of the guide chamber 22 and is fixedly connected to the rotating handle 26. By rotating the handle 26, the operator can make the upper clamping plate 24 and the lower clamping plate 25 slide along the guide chamber 22, thereby controlling the distance between the two clamping plates to clamp or release the photovoltaic panel to be tested. The operation is simple and convenient.
