Description

Technical Field

[0001] This utility model relates to the photovoltaic field, and in particular to a tooling for a solar photovoltaic panel base. Background Technology

[0002] Photovoltaics is a power generation system that converts the radiant energy of sunlight into electrical energy. It mainly consists of three parts: solar panels, controllers, and inverters. Among them, solar panels are solar photovoltaic panels, which are used to realize photoelectric conversion.

[0003] To install solar photovoltaic panels on rooftops, ground surfaces, or water surfaces, a base is needed to fix the panels in place. The structure of the solar photovoltaic panel base can be referenced in Chinese Patent Application No. 202021238430.4, which discloses a photovoltaic base, a photovoltaic base mounting structure, and a photovoltaic support. The photovoltaic base includes a base body; a mounting section located at the upper end of the base body for fixing the photovoltaic column; and at least two guide holes penetrating the base body, with the axial direction of the guide holes inclined to the plane of the base body. The base body includes a first substrate, a second substrate, and a connecting plate. The first substrate and the second substrate are spaced apart, and the connecting plate is located between the first substrate and the second substrate, and is fixedly connected to both substrates.

[0004] Similarly, in the prior art, there exists a base body 0, the specific structure of which is as follows: Figures 3-4 As shown, the base includes a first substrate 01, a second substrate 02, and four connecting plates 03. The first substrate 01 and the second substrate 02 are horizontally arranged, with a gap between them. The connecting plates 03 are vertically arranged and positioned between the first substrate 01 and the second substrate 02, respectively fixedly connected to the first substrate 01 and the second substrate 02. Two adjacent connecting plates 03 are at an angle. Four guide holes 04 are formed through the base body 0. The guide holes 04 penetrate the first substrate 01 and the second substrate 02. The guide holes 04 are distributed in pairs on both sides of the base body 0. The axis of the guide holes 04 is inclined to the surface of the first substrate 01. The axis of the guide holes 04 on the same side is parallel to the axis of the guide holes 04 on different sides, which are at an angle to each other.

[0005] The existing technology provides a base body that uses guide holes to install guide columns, thereby fixing the photovoltaic base to the ground. Therefore, the accuracy of the guide holes affects whether the guide columns can stably fix the base body to the bottom surface. Consequently, when processing the guide holes, if the base body is not firmly fixed and the processing equipment deviates from the required processing position of the base body, the accuracy of the guide holes will be deviated, which will affect the subsequent assembly and use of the photovoltaic base. Utility Model Content

[0006] To address the aforementioned problems, this utility model provides a tooling for a solar photovoltaic panel base, which solves the problem that in the prior art, if the base body is not securely fixed and the processing equipment deviates from the required processing position of the base body during the processing of guide holes, the accuracy of the guide holes will be deviated, affecting the subsequent assembly and use of the photovoltaic base; thus improving the stability of the base body during the processing and making the accuracy and position of the guide holes more precise.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] This utility model provides a tooling for a solar photovoltaic panel base, including a base plate, a boss, and a clamping assembly; if the base plate is horizontally arranged, the boss is located on the upper surface of the base plate; the top plane of the boss is inclined; the top plane of the boss is inclined in the front-back direction;

[0009] The clamping assembly includes two clamping members; the two clamping members are slidably fixed to the top plane of the boss; the two clamping members move towards each other;

[0010] When the solar photovoltaic panel base is assembled on the tooling, the bottom of the extrusion piece, the second substrate and the top plane of the boss form a tight fit; the adjacent ends of the two extrusion pieces are taken as the inner ends, the adjacent side plates of the two adjacent connecting plates are taken as the inner side plates, and the inner side plates of the two adjacent connecting plates form a locking fit with the inner ends of the extrusion pieces.

[0011] The tooling for a solar photovoltaic panel base provided by this utility model preferably further includes two slides; the two slides are respectively located on the left and right sides of the boss; the top plane of the slide is flush with the top plane of the boss; a limiting protrusion is provided on the top plane of the slide; the limiting protrusion extends in the left and right direction; the limiting protrusions on the two slides are located on the same straight line; a limiting groove is provided at the bottom of the extrusion member; the limiting protrusion is embedded in the limiting groove;

[0012] The extrusion piece has a waist hole extending from top to bottom; the waist hole is located above the limiting protrusion; the limiting protrusion has a screw hole; it also includes two fixing bolts; the guide part of the fixing bolt passes through the waist hole and is tightened into the screw hole.

[0013] The tooling for a solar photovoltaic panel base provided by this utility model preferably has a receiving groove at the bottom of the extruder; the receiving groove extends to the inner edge of the extruder; an elastic element is provided in the receiving groove; in the left-right direction, the vertical cross-section of the elastic element gradually increases from the inner end to the outer end.

[0014] The tooling for a solar photovoltaic panel base provided by this utility model preferably has a chamfered rectangular cross-section at the inner end of the extruder.

[0015] The tooling for a solar photovoltaic panel base provided by this utility model preferably has a pressure plate on the top of the extruder; a gap is provided between the pressure plate and the extruder; and several elastic protrusions are distributed on the lower surface of the pressure plate and the top of the extruder.

[0016] The tooling for a solar photovoltaic panel base provided by this utility model preferably includes a limiting member on the top plane of the boss; the limiting member is elongated; the limiting member extends in the left and right direction; the side with the higher top plane of the boss is designated as the front side, the side with the lower top plane of the boss is designated as the rear side, and the limiting member is located near the rear side of the boss.

[0017] The above technical solution has the following advantages or beneficial effects:

[0018] This utility model provides a tooling for a solar photovoltaic panel base. To stably fix the base body onto the drill plate of a drilling machine, the base body needs to be assembled onto the tooling fixture, and then the tooling fixture is fixed to the drill plate. Specifically, the tooling includes a base plate, a boss, and a clamping assembly. The base plate is set horizontally to fit against the drill plate, thereby facilitating the fixing of the base plate and the drill plate. Since the axis of the guide hole is inclined to the plane of the first substrate, it is impossible to form an inclined guide hole by vertically machining the base body with a drill bit. Therefore, a boss needs to be added, with the boss located on the upper surface of the base plate, so that the top plane of the boss is inclined, thereby forming an inclined guide hole when the drill bit is vertically machining. Furthermore, when the drill bit is machining the base body at a lower position, an outwardly inclined guide hole can be formed. For ease of explanation of the tooling structure, the top plane of the boss is inclined in the front-back direction.

[0019] In order to fix the base body to the substrate by means of the clamping assembly, specifically, the clamping assembly includes two pressing members. The two pressing members are slidably fixed on the top plane of the boss. When the base body is placed on the top plane of the boss, the two pressing members move towards each other, so that the two pressing members generate a clamping force on the base body.

[0020] Furthermore, when the solar photovoltaic panel base is assembled on the tooling, two extruders extend between the first substrate and the second substrate. At this time, the bottom of the extruder, the second substrate, and the top plane of the boss form a tight fit, thereby pressing the second substrate onto the top plane of the boss, preventing the base body from moving vertically. Taking the adjacent end of the two extruders as the inner end and the adjacent side of the two adjacent connecting plates as the inner side plate, the inner side plate of the two adjacent connecting plates forms a locking fit with the inner end of the extruder. The inner end of the extruder is locked between the two adjacent connecting plates, preventing the base body from rotating. At the same time, because the two extruders clamp the base body, the base body cannot move on the top plane of the boss. By restricting the movement of the base body in the vertical direction and on the top plane of the boss, and restricting the rotation of the base body, the base body is fixed on the base plate.

[0021] In existing technologies, if the base body is not securely fixed during the processing of guide holes, the processing equipment may deviate from the required processing position of the base body, resulting in deviations in the accuracy of the guide holes and affecting the subsequent assembly and use of the photovoltaic base. The tooling for solar photovoltaic panel bases provided by this utility model, by setting a boss, allows the drill bit to form an inclined guide hole during vertical processing. By setting two clamping parts, the movement of the base body in the vertical direction and on the top plane of the boss is restricted, and the rotation of the base body is also restricted, thus fixing the base body to the base plate. This improves the stability of the base body during processing and makes the accuracy and position of the guide holes more precise. Attached Figure Description

[0026] Figure 4 This is a top view of the base body in the prior art. Detailed Implementation

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0028] Example 1:

[0029] like Figure 1 As shown, Embodiment 1 of this utility model provides a tooling for a solar photovoltaic panel base, including a base plate 1, a boss 2 and a clamping assembly 3; if the base plate 1 is horizontally set, the boss 2 is located on the upper surface of the base plate 1; the top plane of the boss 2 is inclined; the top plane of the boss 2 is inclined in the front-back direction.

[0030] The clamping assembly 3 includes two clamping members 31; the two clamping members 31 are slidably fixed on the top plane of the boss 2; the two clamping members 31 move towards each other;

[0031] When the solar photovoltaic panel base is assembled on the tooling, the bottom of the extrusion piece 31, the second substrate 02 and the top plane of the boss 2 form a tight fit; the adjacent ends of the two extrusion pieces 31 are taken as the inner ends, and the adjacent side plates of the two adjacent connecting plates 03 are taken as the inner side plates, and the inner side plates of the two adjacent connecting plates 03 form a locking fit with the inner ends of the extrusion pieces 31.

[0032] When using the tooling for a solar photovoltaic panel base provided in Embodiment 1 of this utility model, the solar photovoltaic panel base, i.e., the base body 0 in the prior art, is placed on the top plane of the boss 2, so that the lower surface of the second substrate 02 is in contact with the top plane of the boss 2; the clamping assembly 3 clamps the base body 0. Specifically, the two pressing members 31 are moved towards each other, so that the inner end of the pressing member 31 extends between the first substrate 01 and the second substrate 02. At this time, the bottom of the pressing member 31 presses the second substrate 02 onto the top plane of the boss 2, and the inner edge of the pressing member 31 is in contact with the surface of the connecting plate 03, forming a locking fit. A drilling machine is used to open guide holes 04 on the first substrate 01 and the second substrate 02. The drilling machine structure can refer to a drilling machine mechanism and drilling machine disclosed in Chinese Patent Application No. 201510875425.1. The tooling with the base body 0 is placed on the drill plate of the drilling machine and fixed. A drill bit of appropriate size is connected to the drill sleeve and perpendicular to the drill plate. Inclined guide holes 04 are opened on the first substrate 01 and the second substrate 02 which are in a lower position. After the two guide holes 04 on the same side are processed, the position of the base body 0 is adjusted so that the other side of the base body 0 is in a lower position, and the two guide holes 04 on the other side are processed.

[0033] The tooling for a solar photovoltaic panel base provided in Embodiment 1 of this utility model requires the base body 0 to be stably fixed on the drill plate of a drilling machine. The base body 0 is assembled onto a tooling fixture, and then the tooling fixture is fixed to the drill plate. Specifically, the tooling includes a base plate 1, a boss 2, and a clamping assembly 3. The base plate 1 is horizontally positioned to fit against the drill plate, facilitating the fixing of the base plate 1 to the drill plate. Since the axis of the guide hole 04 is inclined to the plane of the first substrate 01, vertical machining of the base body 0 with a drill bit cannot form an inclined guide hole 04. Therefore, a boss 2 is added, positioned on the upper surface of the base plate 1, with the top plane of the boss 2 inclined. This allows the drill bit to form an inclined guide hole 04 during vertical machining. Furthermore, when the drill bit processes the lower-position base body 0, an outwardly inclined guide hole 04 can be formed. For ease of explanation of the tooling structure, the top plane of the boss 2 is inclined in the front-back direction.

[0034] In order to fix the base body 0 to the base plate 1 by means of clamping assembly 3, specifically, clamping assembly 3 includes two pressing members 31. The two pressing members 31 are slidably fixed on the top plane of the boss 2. When the base body 0 is placed on the top plane of the boss 0, the two pressing members 31 move towards each other, so that the two pressing members 31 generate a clamping force on the base body 0.

[0035] Furthermore, when the solar photovoltaic panel base is assembled on the tooling, two extrusion members 31 extend between the first substrate 01 and the second substrate 02. At this time, the bottom of the extrusion member 31, the second substrate 02, and the top plane of the boss 2 form a tight fit, thereby pressing the second substrate 02 onto the top plane of the boss 2, preventing the base body 0 from displacing in the vertical direction. Taking the adjacent end of the two extrusion members 31 as the inner end, and the adjacent side surface of the two adjacent connecting plates 03 as the inner side surface, the inner side surface of the two adjacent connecting plates 03 forms a locking fit with the inner end of the extrusion member 31. The inner end of the extrusion member 31 is locked between the two adjacent connecting plates 03, preventing the base body 0 from rotating. At the same time, because the two extrusion members 31 clamp the base body 0, the base body 0 cannot move on the top plane of the boss 2. By restricting the movement of the base body 0 in the vertical direction and on the top plane of the boss 2, and restricting the rotation of the base body 0, the base body 0 is fixed on the base plate 1.

[0036] In existing technologies, if the base body is not securely fixed during the processing of guide holes, the processing equipment may deviate from the required processing position of the base body, resulting in a deviation in the accuracy of the guide hole and affecting the subsequent assembly and use of the photovoltaic base. The tooling for a solar photovoltaic panel base provided in Embodiment 1 of this utility model, by setting a boss 2, allows the drill bit to form an inclined guide hole 04 during vertical processing. By setting two clamping members 31, the movement of the base body 0 in the vertical direction and on the top plane of the boss 2 is restricted, and the rotation of the base body 0 is also restricted, so that the base body 0 is fixed on the base plate 1. This improves the stability of the base body 0 during processing and makes the accuracy and position of the guide hole 04 more precise.

[0037] like Figure 1 As shown, the tooling for a solar photovoltaic panel base provided in Embodiment 1 of this utility model preferably includes two slide blocks 4 to enable the extruder 31 to be slidably fixed on the top plane of the boss 2. To facilitate the drilling of the base body 0, the two slide blocks 4 are located on the left and right sides of the boss 2 respectively. The top plane of the slide block 4 is flush with the top plane of the boss 2, so that the extruder 31 can slide continuously on the top plane of the slide block 4 and the top plane of the boss 2. To limit the sliding trajectory of the extruder 31, a limiting protrusion 41 is provided on the top plane of the slide block 4. The limiting protrusion 41 extends in the left and right direction. A limiting groove 311 is provided at the bottom of the extruder 31. The limiting protrusion 41 is embedded in the limiting groove 311, so that the extruder 31 can move along the extending direction of the limiting protrusion 41. Furthermore, the limiting protrusions 41 on the two slide blocks 4 are located on the same straight line, so that the two extruders 31 can stably clamp the base body 0.

[0038] To fix the slidable extruder 31 to the base plate 1, specifically, the extruder 31 has a through hole 312 extending from top to bottom. The through hole 312 is located above the limiting protrusion 41 and communicates with the limiting groove 311. The cross-section of the through hole 312 is smaller than the cross-section of the limiting groove 311. A screw hole 411 is provided on the limiting protrusion 41, and two fixing bolts 5 are also included. The guide part of the fixing bolt 5 passes through the through hole 312 and can be tightened into the screw hole 411. The fixing bolts 5 press the extruder 31 onto the slide block 4 to prevent the extruder 31 from moving. The through hole 312 can still fix the extruder 31 to the slide block 4 after the position of the extruder 31 is adjusted.

[0039] like Figure 2As shown, the tooling for a solar photovoltaic panel base provided in Embodiment 1 of this utility model, preferably, in order to form a tight fit between the bottom of the extruder 31, the second substrate 02, and the top plane of the boss 2, thereby pressing the second substrate 02 onto the top plane of the boss 2, specifically, the bottom of the extruder 31 is provided with a receiving groove 313 for receiving the second substrate 02. The receiving groove 313 extends to the inner edge of the extruder 31, so that when the extruder 31 moves toward the base body 0, the second substrate 02 can be directly inserted into the receiving groove 313; in order to achieve pressing the second substrate 02 onto the top plane of the boss 2 by the extruder 31, the receiving groove 313... The base body 0 is provided with an elastic element 3131. When the second substrate 02 is inserted into the gap between the receiving groove 313 and the top plane of the boss 2, the second substrate 02 squeezes the elastic element 3131, so that the elastic element 3131, the second substrate 02 and the boss 2 form a tight fit, preventing the base body 0 from shaking due to the small gap. Furthermore, in order to prevent the second substrate 02 from having difficulty being inserted into the gap between the receiving groove 313 and the top plane of the boss 2, the vertical cross section of the elastic element 3131 gradually increases from the inner end to the outer end in the left-right direction, so that the second substrate 02 can be inserted from the larger gap to the smaller gap, improving the ease of assembly of the base body 0 on the tooling.

[0040] like Figure 1 As shown, the tooling for a solar photovoltaic panel base provided in Embodiment 1 of this utility model preferably has a cross-section of the inner end of the extrusion member 31 that is chamfered rectangular, and its chamfered plane can be attached to the inner side surface of two adjacent connecting plates 03 that are angled together, thereby forming a locking fit.

[0041] like Figures 1-2 As shown, the tooling for a solar photovoltaic panel base provided in Embodiment 1 of this utility model preferably has the following features: since the first substrate 01 and the second substrate 02 are only fixedly connected by a connecting plate 03, and both the first substrate 01 and the second substrate 02 need to be processed, fixing only the second substrate 02 may easily damage the first substrate 01; in order to avoid damage to the first substrate 01 during processing, specifically, a pressure plate 6 is provided on the top of the extruder 31 to improve the stability of the base body 0 during processing; a gap is provided between the pressure plate 6 and the extruder 31 to accommodate the insertion of the first substrate 01, and several elastic protrusions 531 are distributed on the lower surface of the pressure plate 6 and the top of the extruder 31 to buffer the stress generated on the first substrate 01 during processing, and at the same time form a tight fit with the first substrate 01.

[0042] like Figure 1As shown, the tooling for a solar photovoltaic panel base provided in Embodiment 1 of this utility model preferably includes a limiting member 21 on the top plane of the boss 2 to position the base body 0 in order to further improve the assembly efficiency of the base body 0 on the tooling. Specifically, the limiting member 21 is elongated and extends in the left and right direction, with the higher side of the top plane of the boss 2 as the front side and the lower side of the top plane of the boss 2 as the rear side. The limiting member 21 is close to the rear side of the boss 2. When the base body 0 is placed on the top plane of the boss 2, the base body 0 can slide naturally to the limiting member 21. At this time, one edge of the second substrate 02 is aligned with the limiting member 21, which facilitates the inner end of the extrusion member 31 to form a locking fit with the inner side of the two adjacent connecting plates 03.

[0043] In summary, the tooling for solar photovoltaic panel bases provided by this utility model can solve the problem that when processing guide holes in the prior art, if the base body is not fixed securely, the processing equipment may deviate from the required processing position of the base body, which will cause deviations in the accuracy of the guide holes and affect the subsequent assembly and use of the photovoltaic base; thereby improving the stability of the base body during the processing and making the accuracy and position of the guide holes more precise.
