Description

Technical Field

[0001] The invention relates to the technical field of brackets for installing solar photovoltaic panels, and more specifically to a photovoltaic panel installation water tank bracket and a draw hook used in combination with the bracket. Background Art

[0002] Anhui Yuxin Electric Power Engineering Co., Ltd. applied for an invention patent for an integrated water tank bracket for photovoltaic panels (application number 201910115863.6) and a fixed structure for an integrated water tank bracket for photovoltaic panels (application number 202010466144.1). The utility model patent applied for at the same time has been authorized. The patented technology solves the problems of installation firmness and drainage of photovoltaic panels in the past, and has achieved huge economic benefits for the company. It also provides solutions to the installation problems of the photovoltaic industry and greatly contributes to the development of the industry. This year, the company established Anhui Yuxin New Materials Co., Ltd., which is dedicated to the research and development, production and sales of photovoltaic panel brackets.

[0003] In actual use, the following problems need to be improved:

[0004] (1) Heavy rainfall places higher demands on the drainage capacity of the water tank in the original patent. Our company needs to design a new water tank bracket to increase the drainage capacity of the water tank;

[0005] (2) The installation firmness of the original fasteners has met the requirements, but it is necessary to first install and fix the lower clamp block and the middle add-on block on the sink one by one, and then install the upper pressure block to fasten the photovoltaic panel. There are two bolt tightening processes, and the installation labor cost is relatively high. The company needs to design new fastener components for use with the sink to achieve the purpose of easy installation and labor saving. Summary of the invention

[0006] In view of the problems existing in the prior art, the purpose of the present invention is to provide a photovoltaic panel installation gutter bracket and a hook used therewith, so as to solve the following problems in the prior art: 1. the drainage volume is small, and when encountering heavy rainfall, the water volume is too large to be discharged in time, and the rainwater overflows the gap between the photovoltaic panel and the gutter to cause leakage; 2. the old-style lower clamping block and the middle clamping block are fixed to the gutter by a bolt structure, and the installation process is complicated, the installation efficiency is low, and the labor cost is high.

[0007] To solve the above problems, the present invention adopts the following technical solution: a water tank bracket for installing photovoltaic panels, comprising the following components: a water tank, installed on a building or the ground, supporting two adjacent photovoltaic panels respectively through two groove edges of the water tank, and making the longitudinal joint seam of the two adjacent photovoltaic panels located above the groove of the water tank; a fixing structure, fixedly connected to the water tank, fixing the water tank to the building or the ground through a bolt structure; a hook structure, arranged on the inner wall of the water tank, for limiting and fixing the hook foot of the pull hook.

[0008] Furthermore, the hook structure is a stop bar arranged on the inner side wall of the water tank, and the stop bar forms a right angle / acute angle with the inner side wall below it.

[0009] Furthermore, the hook structure is an angular protrusion formed by bending the middle part of the side wall of the water tank inward and downward.

[0010] Furthermore, the fixing structure is an "L"-shaped plate connected to the edge of the sink.

[0011] Furthermore, the "L"-shaped plate includes a diagonal support plate formed by bending and extending the side wall at the edge of the water tank outward and downward to be flush with / exceed the bottom of the water tank, and a side strip formed by bending and extending the lower edge of the diagonal support plate outward in a horizontal direction.

[0012] A draw hook used in conjunction with the photovoltaic panel mounting water tank bracket, the draw hook comprising a cross bridge and hook feet symmetrically arranged at both ends of the cross bridge, the hook feet hooking at the bottom of the hook structure.

[0013] Furthermore, a limiting protrusion is provided in the middle of the transverse bridge, and the width of the limiting protrusion is the same as the width of the longitudinal joint.

[0014] Compared with the prior art, the advantages of the present invention are:

[0015] (1) The new type of water tank has been redesigned. On the basis of the same width and height, without affecting its support and stability, the cross-sectional area of ​​the water tank is increased, so that the water discharge capacity is larger and the water flow can be discharged quickly. The water level in the water tank will not rise too high and leak through the gap between the photovoltaic panel and the water tank bracket, causing rain leakage.

[0016] (2) The new type of hook is part of the fastener, replacing the "lower clamp block and middle clamp block" of the original fastener. It is used in conjunction with the hook structure of the sink, eliminating the need for separate fixing steps, achieving quick installation and reducing labor costs.

[0017] (3) The coordinated design of the new sink and the new hook not only increases the cross-sectional area of ​​the sink and improves the drainage volume, but also reduces the cross-sectional area of ​​the fasteners, thereby reducing the obstruction of the fasteners to the water flow. These two breakthroughs have increased the drainage volume of the new sink by more than 2.5 times. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention;

[0030] Embodiment 1:

[0031] like Figure 1-9As shown, a water tank bracket for installing photovoltaic panels includes the following components: a water tank 1, which is installed on a building or the ground, and supports two adjacent photovoltaic panels 10 respectively through two groove edges 11 of the water tank 1, and the longitudinal joint seam of the two adjacent photovoltaic panels 10 is located above the notch 12 of the water tank 1; a fixing structure 2, which is fixedly connected to the water tank 1, and the water tank 1 is fixed to the building or the ground through a bolt structure 4; a hook structure 3, which is arranged on the inner wall of the water tank 1, and is used to limit and fix the hook foot 52 of the pull hook 5.

[0032] Furthermore, the hook structure 3 is a stop bar 31 disposed on the inner wall of the water tank 1 , and the stop bar 31 forms a right angle / acute angle with the inner wall below it.

[0033] Furthermore, the hook structure 3 is an angular protrusion 32 formed by bending the middle part of the side wall of the water tank 1 inwardly and downwardly.

[0034] Furthermore, the fixing structure 2 is an "L"-shaped plate connected to the edge 11 of the water tank 1.

[0035] Furthermore, the "L"-shaped plate includes a diagonal support plate 21 formed by bending and extending the side wall at the groove edge 11 of the water tank 1 outward and downward to be flush with / exceed the bottom of the water tank, and a side strip 22 formed by bending and extending the lower edge of the diagonal support plate 21 outward in a horizontal direction.

[0036] A draw hook used in conjunction with the photovoltaic panel mounting water tank bracket, the draw hook 5 is composed of a cross bridge 51 and hook feet 52 symmetrically arranged at both ends of the cross bridge, and the hook feet 52 are hooked at the lower part of the hook structure 3.

[0037] Furthermore, a limiting protrusion 53 is provided in the middle of the transverse bridge 51 , and the width of the limiting protrusion 53 is the same as the width of the longitudinal joint.

[0038] Embodiment 2:

[0039] (1) Development of basic water tank bracket:

[0040] like Figure 1-4 As shown, a water tank bracket with a customized square trough structure is provided with two stop bars (i.e., hook structures) symmetrically arranged on the inner wall of the square trough. The cross-section of the stop bar is sheet-shaped or solid triangular. A metal block (fixed structure) parallel to the bottom of the trough is welded to the bottom of the outer wall of the square trough. The metal block is tightened and fixed to the metal frame on the ground / top of the building / top of the factory building with self-tapping screws to fix the square trough. The roofs of factory buildings are mostly steel purlin structures.

[0041] According to the above method, multiple water tank brackets with square trough structures are longitudinally installed at fixed intervals on the metal frame (i.e. purlin) on the ground / top of the building / top of the factory building, and the photovoltaic panels are erected on the groove edges of two adjacent square grooves. The longitudinal joint between the two adjacent photovoltaic panels is located above the notch of the square groove, and the photovoltaic panels are erected.

[0042] The above-mentioned stop bar can be a horizontal or oblique stop bar symmetrically arranged on the inner side wall, or a "7"-shaped stop bar symmetrically arranged on the inner wall of the sink bottom. The design of the pull hook corresponds to the design of the stop bar.

[0043] Taking into account that the basic square groove relies on the strength of the side wall itself to support the photovoltaic panel, requirements are put forward for its material itself. It is customized and manufactured in an aluminum profile production company. Its internal stop bar and external fixing structure can be customized by one-piece molding.

[0044] (2) Development of improved water tank bracket:

[0045] Combining the company's previous experience with integrated sinks, we designed an integrated sink bracket that can be made using cold pressing and bending technology.

[0046] like Figure 5-9 As shown, based on the square groove, the middle part of the side wall is bent inward and downward to form an acute-angled protrusion to form a hook structure, and the side wall at the edge of the groove of the sink is bent outward and downward and extended until it is flush with the bottom of the sink / exceeds the bottom of the sink, and then bent outward and extended in the horizontal direction to form a fixed structure. This structure can be made of a whole piece of magnesium-aluminum-zinc plate through a cold pressing and bending process, and its production cost is low. The "M"-shaped structure enhances the support, stability and firmness of the sink. Compared with the basic type of sink made of customized aluminum alloy profiles, the material cost is greatly reduced.

[0047] (3) Development of the pull hook: The structure of the pull hook matches the shape of the hook structure of the sink.

[0048] like Figure 2-5 As shown, the hook 5 is composed of a cross bridge 51 and hook feet 52 symmetrically arranged at both ends of the cross bridge. The hook feet 52 are used in conjunction with the hook structure 3. The cross bridge 51 tightens and fixes the photovoltaic panel with the upper "upper pressure block (original patent)" through a bolt structure. A screw rod perpendicular to the cross bridge can be set on the cross bridge, and the "upper pressure block" and the hook can be tightened and fixed by a nut; or a self-tapping screw can be used to screw down from the upper "upper pressure block" and then pass through the cross bridge to tighten and fix the two.

[0049] like Figure 2-5As shown, when the hook structure is inwardly horizontal / inwardly downward, the hook foot of the pull hook is outwardly horizontal / outwardly upward; when the hook structure is outwardly horizontal / outwardly downward, the hook foot of the pull hook is inwardly horizontal / inwardly upward.

[0050] Such as: Figure 4 As shown, the hook structure is located on the inner wall of the basic sink and symmetrically points to the bottom of the sink. At this time, the hook foot of the pull hook points outward and obliquely upward, and the angle matches the hook structure.

[0051] like Figure 2 As shown, the hook structure is located on the bottom of the basic water tank and is symmetrically shaped like a "7". The opening of the hook structure faces inward, and the hook foot of the pull hook faces outward like a "J" shape.

[0052] like Figure 3 As shown, when the opening of the hook structure faces outward, the hook foot of the pull hook faces inward to form a "door" shape.

[0053] like Figure 5 As shown, when the hook structure is located on the angular protrusion on the side wall of the improved sink, the hook foot of the pull hook points outward and obliquely upward, and the angle matches the hook structure.

[0054] The limiting protrusions arranged on the cross bridge have a width the same as that of the longitudinal joint seam and the groove portion of the "upper pressure block", and are used to limit and fix the photovoltaic panel to achieve better support and firmness.

[0055] The length of the hook in its longitudinal direction has various specifications: short specification: 2-5cm, on average, multiple can be installed on a one-meter-long sink bracket, and each hook is installed with a bolt structure; medium specification: 10-15cm, on average, 2-3 points can be installed on a one-meter-long sink bracket, and 1-2 bolt structures are installed on each hook; long specification: 20-40cm, on average, 1-2 points can be installed on a one-meter-long sink bracket, and 2 bolt structures are installed on each hook. After the tensile test, the above installation modes all meet the industry's requirements for 100-150 kg tensile test requirements, among which the long specification has the best result, reaching a tensile test result of 178 kg, which exceeds the industry standard.

[0056] Embodiment: 3:

[0057] Installation of photovoltaic panels:

[0058] The prepared water tank is installed on the top frame of the standardized factory building to replace the ordinary roof of the original design. The water leakage prevention requirements of the roof are higher. The present invention redesigns the structure of the water tank to increase the drainage volume and reduce the water intake volume, completely solving the problem of leakage caused by insufficient drainage volume of the water tank.

[0059] Install the prepared water tank longitudinally on the top frame 6 (i.e., purlin) of the factory building, insert multiple hooks into the water tank from one side of the water tank, so that the hook feet of the hooks are located below the hook structure, and then adjust the hooks to a suitable position, and then set up the photovoltaic panels on the two adjacent water tanks, and use the "upper pressure block in the original patent" to tighten the photovoltaic panels on the water tank using the bolt structure to complete the fixing of the water tank. The longitudinal joints between the photovoltaic panels are located above the water tank, and the transverse joints are located on the "transverse water guide groove of the original patent", completing the collection of rainwater and the fixing of the photovoltaic panels.

[0060] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
