Description

Technical Field

[0001] This utility model relates to the field of photovoltaic equipment installation technology, and in particular to a photovoltaic equipment mounting bracket. Background Technology

[0002] Photovoltaic equipment is a device that uses the photovoltaic effect to convert sunlight into electrical energy. Its core principle is to use solar panels made of semiconductor materials (such as silicon) to directly convert light energy into electrical energy, which is clean and sustainable.

[0003] A photovoltaic (PV) panel bracket, also known as a solar photovoltaic (PV) bracket, is a metal structure specifically designed for installing and fixing solar panels. For example, Chinese Patent Publication No. "CN220823009U" discloses a PV mounting bracket, which includes a support frame. Two support frames are arranged horizontally and connected by a connecting rod. Mounting frames are fixedly connected to both ends of the top of each support frame. Several n-shaped fixing rods are fixedly connected at equal intervals to the top of the mounting frame. A fixing frame is fixedly connected to the top of one end of the mounting frame. A rotating shaft is rotatably inserted into the fixing frame. A tarpaulin is wrapped around the shaft wall of the rotating shaft. A hook is fixedly connected to the end of the tarpaulin away from the rotating shaft, and the hook matches the n-shaped fixing rod. The beneficial effects of this invention are: the support frame and mounting frame can support the PV panel; the multiple n-shaped fixing rods evenly spaced above the mounting frame do not obstruct the PV panel; and in severe weather, the tarpaulin on the rotating shaft can be stretched, with the tarpaulin positioned above the n-shaped fixing rods, effectively protecting the PV panel and preventing damage.

[0004] In practice, the photovoltaic panels are protected by covering them with tarpaulins. However, the tarpaulin needs to be rolled up manually, which affects the rolling efficiency. Also, there is no fixed structure between the shaft and the support frame. Therefore, for photovoltaic panels of different widths, it is necessary to replace the tarpaulin with one of the appropriate length, which is not very practical. Utility Model Content

[0005] The purpose of this utility model is to solve the shortcomings of the existing technology, such as the inconvenience of rolling up the tarpaulin and the poor adaptability of the tarpaulin to cover photovoltaic panels of different widths, and to propose a photovoltaic equipment mounting bracket.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a mounting bracket for a photovoltaic device, including several sets of photovoltaic units mounted on the bracket, and a protective component for shielding the photovoltaic units. The protective component includes a winding drum, which is fixedly connected to one side of the bracket, and a tarpaulin is connected to the inside of the winding drum via the winding component.

[0008] The winding assembly includes a fixed seat and a movable seat, and a locking structure is provided between the fixed seat and the movable seat. The tarpaulin is covered above the photovoltaic unit through the locking structure.

[0009] Furthermore, the protective assembly also includes a fixing rod and a hook. The fixing rod is fixedly connected to the top of the bracket between two adjacent sets of photovoltaic units. The hook is fixedly connected to the movable end of the tarpaulin and hung on the fixing rod.

[0010] Furthermore, the winding assembly also includes a rotating shaft, which is rotatably connected inside the winding drum. The outer periphery of the rotating shaft is fixedly connected to the fixed end of the tarpaulin, and one end of the rotating shaft is also fixedly connected to the movable seat.

[0011] The fixed seat and the movable seat are rotatably connected by a coil spring, and the fixed seat is fixedly connected to the inside of one end of the winding drum.

[0012] Furthermore, the locking structure includes a ratchet, a connecting part is rotatably connected to the midpoint of the fixed seat, the two ends of the coil spring are respectively connected to the connecting part and the inner wall of the fixed seat, one end of the connecting part passes through the fixed seat and is fixedly connected to the ratchet.

[0013] Furthermore, it also includes an unlocking component, which is rotatably connected to the side of the fixed base via a shaft and a torsion spring. The side of the unlocking component has a protrusion, and the ratchet engages with the protrusion along the stretching direction of the tarpaulin to cooperate with the hook to tighten the tarpaulin.

[0014] Furthermore, the top of the unlocking component is slidably connected to a groove opened on the outer wall of the winding drum. One end of the groove is provided with a deformation stop. The top of the unlocking component has a rod-shaped structure, and its top is locked in the deformation stop by abutting and sliding.

[0015] The photovoltaic equipment mounting bracket proposed in this utility model has the following advantages: A winding drum is provided on one side of the top of the bracket. The winding drum uses an internal winding assembly to wind up the tarpaulin. The tarpaulin, through stretching and the use of hooks, can shield photovoltaic panels of different widths within a certain range. Furthermore, a locking structure is provided between the tarpaulin and the winding drum. This locking structure is used to tighten the stretched tarpaulin, creating a certain gap between the tarpaulin and the photovoltaic panel. This prevents hail, gravel, etc., from directly impacting the photovoltaic panel through the tarpaulin, and also prevents the tarpaulin from stretching under stress, thus maintaining its protective effect on the photovoltaic panel.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-5 A photovoltaic equipment mounting bracket includes several sets of photovoltaic units 2 mounted on a bracket 1, and a protective component 3 for shielding the photovoltaic units 2. The protective component 3 includes a winding drum 31, which is fixedly connected to one side of the bracket 1. A tarpaulin 32 is connected inside the winding drum 31 via a winding component 4.

[0024] The winding assembly 4 includes a fixed base 41 and a movable base 42. A locking structure 5 is provided between the fixed base 41 and the movable base 42. The tarpaulin 32 is covered above the photovoltaic unit 2 by the locking structure 5.

[0025] It should be added that the photovoltaic unit 2 is a photovoltaic panel, which is arranged on the inclined end face of the support 1. The tarpaulin 32 is stretched and used in conjunction with the hooks 34 and the fixing rods 33 to cover the photovoltaic panel.

[0026] Specifically, the locking structure 5 is used to tighten the stretched tarpaulin 32, thereby creating a certain gap between the tarpaulin 32 and the photovoltaic panel. On the one hand, this prevents hail, gravel, etc. from directly penetrating the tarpaulin 32 and impacting the photovoltaic panel, allowing the tarpaulin 32 to withstand the impact and protect the photovoltaic unit 2. On the other hand, the locking mechanism prevents the tarpaulin 32 from stretching under stress and failing to bear the force, thus affecting the protective effect on the photovoltaic panel.

[0027] Furthermore, the protective component 3 also includes a fixing rod 33 and a hook 34. The top of the bracket 1 is fixedly connected to the fixing rod 33 between two adjacent sets of photovoltaic units 2. The hook 34 is fixedly connected to the movable end of the tarpaulin 32 and hung on the fixing rod 33.

[0028] Specifically, the fixing rod 33 has a U-shaped structure, and the fixing rod 33 is fixedly connected between two adjacent photovoltaic units 2. Then, under the action of the locking structure 5, the tarpaulin 32 can shield and protect photovoltaic panels of different widths within a certain range according to actual needs.

[0029] Furthermore, the winding assembly 4 also includes a rotating shaft 43, which is rotatably connected inside the winding drum 31. The outer periphery of the rotating shaft 43 is fixedly connected to the fixed end of the tarpaulin 32, and one end of the rotating shaft 43 is also fixedly connected to the movable seat 42.

[0030] The fixed seat 41 and the movable seat 42 are rotatably connected by a coil spring 44, and the fixed seat 41 is fixedly connected to the inside of one end of the winding drum 31.

[0031] In this embodiment, as Figure 4 As shown, the two ends of the coil spring 44 are respectively connected to the connecting part 45 and the inner wall of the fixed seat 41. The connecting part 45 is provided in pairs, and the other connecting part 45 is fixedly connected to the end face of the movable seat 42. The connecting part 45 and the other connecting part 45 rotate synchronously through splines and grooves.

[0032] Specifically, when stretching the tarpaulin 32, the movable seat 42 drives a pair of connecting parts 45 to rotate synchronously. The rotation of the connecting parts 45 causes the coil spring 44 to be compressed. Thus, when releasing the tarpaulin 32, the rotating shaft 43 reverses under the action of the coil spring 44, thereby automatically rewinding the tarpaulin 32.

[0033] Of course, the outer wall of the winding drum 31 is provided with a straight groove that connects to the interior, and the tarpaulin 32 is slidably connected in the straight groove.

[0034] More specifically, the locking structure 5 includes a ratchet 51, a connecting part 45 is rotatably connected to the midpoint of the fixed seat 41, the two ends of the coil spring 44 are respectively connected to the connecting part 45 and the inner wall of the fixed seat 41, one end of the connecting part 45 passes through the fixed seat 41 and is fixedly connected to the ratchet 51.

[0035] In general, it also includes an unlocking component 52, which is rotatably connected to the side of the fixed base 41 via a shaft and a torsion spring 53. The side of the unlocking component 52 has a protrusion 521, and the ratchet 51 engages with the protrusion 521 along the stretching direction of the tarpaulin 32 to cooperate with the hook 34 to tighten the tarpaulin 32.

[0036] Finally, the top of the unlocking member 52 is slidably connected to the groove 311 opened on the outer wall of the winding drum 31. One end of the groove 311 is provided with a deformation stop 312. The top of the unlocking member 52 has a rod-shaped structure, and its top is locked in the deformation stop 312 by abutting and sliding.

[0037] In this embodiment, the specific structure between the ratchet 51 and the protrusion 521 can be referred to the structure of the ratchet pawl in the prior art;

[0038] Normally, the ratchet 51 is engaged with the protrusion 521 along the stretching direction of the tarpaulin 32. That is, the tarpaulin 32 cannot be stretched without unlocking the ratchet 51, so as to prevent the tarpaulin 32 from stretching under force.

[0039] In specific operation, the two ends of the torsion spring 53 are fixedly connected to the fixed base 41 and the unlocking member 52 respectively. The torsion spring 53 is used to reset the unlocking member 52 so as to drive the protrusion 521 to lock with the ratchet 51.

[0040] Specifically, by rotating the unlocking component 52, the protrusion 521 is disengaged from the ratchet 51, allowing the tarpaulin 32 to be stretched freely.

[0041] It is worth mentioning that the winding drum 31 is preferably made of materials with deformation capabilities such as rubber and plastic. The deformation stop part 312 specifically includes deformation grooves. The deformation grooves are arranged on both sides of the end of the slide groove 311, and one end of the groove is connected to the slide groove 311. The opposite sides of the movable ends of the pair of deformation grooves extend outward to form a protruding structure. The pair of protruding structures slide against the unlocking member 52 to fix the unlocking member 52 so as to allow the tarpaulin 32 to be stretched freely.

[0042] Working method: During operation, rotating the unlocking part 52 drives the protrusion 521 to disengage from the ratchet 51, and after the unlocking part 52 slides against the pair of protruding structures, the pair of protruding structures stop the unlocking part 52, so that the tarpaulin 32 can be freely stretched.

[0043] While the tarpaulin 32 is being stretched, a pair of connecting parts 45 are driven to rotate synchronously through the movable seat 42. The rotation of the connecting parts 45 causes the coil spring 44 to be compressed. Thus, when the tarpaulin 32 is released, the rotating shaft 43 reverses under the action of the coil spring 44, thereby automatically rewinding the tarpaulin 32.

[0044] The tarpaulin 32, together with the fixing rod 33 and hook 34, covers the photovoltaic panel to protect it.

[0045] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
