Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaics, in particular to a photovoltaic component protection device. Background Art

[0002] Existing photovoltaic power generation devices generally use photovoltaic modules to generate electricity. However, in actual applications, severe convective weather such as hail and heavy rain is often encountered. Hail, large raindrops, etc. falling on photovoltaic modules can easily cause damage to the photovoltaic modules. The protective device of the prior art usually sets a protective net and winds it on a winding shaft. When encountering severe weather, the protective net is unwound and opened by a motor to block the photovoltaic module. However, since the above-mentioned protective device relies on electrical components such as motors to unfold and store the protective net, it may not be able to effectively perform the protective operation in the event of a power outage, and there is a certain protection risk.

[0009] In one embodiment, a through slot is provided in the counterweight block, the angle between the extending direction of the through slot and the gravity direction is less than 90°, and the stopper is inserted in the through slot;

[0010] A first limiting groove is provided on the groove wall of the through groove, a second limiting groove is provided on the outer surface of the limiting member at a position corresponding to the first limiting groove, and both ends of the clamping member are respectively located in the first limiting groove and the second limiting groove; the second limiting groove has a preset distance from the bottom of the support platform.

[0011] In one embodiment, the limiting member is constructed as a guide rail structure, and the limiting member extends along the direction of gravity;

[0012] The second limiting groove is located on a side of the limiting member away from the bottom of the supporting platform.

[0013] In one of the embodiments, the trigger assembly further includes an elastic reset member and a connecting member;

[0014] The elastic reset member is clamped between the first groove bottom wall of the first limiting groove and the clamping member; a side of the clamping member facing the elastic reset member is connected to the induction plate through a connecting member.

[0015] In one embodiment, the induction plate includes a main plate and a transition plate connected to each other, and the angle between the main plate and the transition plate is an obtuse angle;

[0016] The transition plate is hinged to the counterweight block, and the end of the transition plate facing away from the main plate is connected to the connecting piece.

[0017] In one of the embodiments, an avoidance groove is provided at a position of the sensor plate on the surface of the counterweight block, the sensor plate is hinged on the side groove wall of the avoidance groove, and a connecting hole is provided on the bottom wall of the avoidance groove, one end of the connecting hole is connected to the avoidance groove, and the other end is connected to the first limit groove, and the connecting piece is passed through the connecting hole.

[0018] In one embodiment, the support platform includes a support plate and a support leg disposed at the bottom of the support plate;

[0019] The support plate is arranged obliquely relative to the direction of gravity;

[0020] The winding roller and the limiting member are both connected to the support plate, and the setting height of the winding roller is lower than the setting height of the limiting member.

[0021] In one of the embodiments, a fixed pulley is further provided on the support plate, and the fixed pulley is located on the top side of the limiting member. The driving rope is wound around the fixed pulley and then connected to the counterweight block.

[0022] In one embodiment, the winding assembly further includes a spring assembly, the spring assembly includes a spring box and a spring spring, one end of the spring spring is connected to the spring box, and the other end of the spring spring is connected to the winding roller.

[0024] The beneficial effects of the above photovoltaic module protection device are:

[0025] The clamping member is connected to the counterweight block and the position limiting member respectively, and the counterweight block and the position limiting member are relatively fixed by the clamping member. After the connection between the counterweight block and the position limiting member is released, the counterweight block will fall toward the bottom of the support platform under the action of its own gravity.

[0026] Since the induction plate is hinged to the counterweight, it can rotate around its hinge axis when the induction plate is under pressure. Since the clamping member and the induction plate are transmission-connected, the induction plate is configured to rotate when under pressure, and drive the clamping member to disengage from the limiter, so that the counterweight falls, and the flexible protective member is driven by the driving rope to unwind from the winding roller and be stretched on the top side of the support platform. Therefore, when the induction plate rotates, the clamping member is driven to disengage from the limiter, and the connection between the counterweight and the limiter is released. The counterweight falls toward the bottom of the support platform under the action of gravity, thereby pulling the driving rope. Since the winding roller and the limiter are connected to the opposite sides of the support platform, the driving rope is located on the top side of the support platform and the two ends are respectively connected to the counterweight and the flexible protective member. Therefore, after the driving rope is pulled, the flexible protective member will be gradually pulled to unwind from the winding roller, and move along the pulling direction of the driving rope, so as to be stretched on the top of the support platform to protect the photovoltaic components on the top of the support platform. During the protection startup process when encountering extreme weather, if falling objects from the air, such as hail, fall onto the sensor plate, the sensor plate will be pressurized and respond automatically. Compared with the prior art that relies on motor drive, there is no need to connect to a power supply, and the protection reliability is higher.

[0027] In other words, the photovoltaic module protection device of the embodiment of the present application adopts a purely mechanical structure design, which means that even in the event of a power outage, the device can still operate normally relying on its own mechanical power, ensuring that the photovoltaic modules are protected in a timely manner in severe weather.

[0041] The photovoltaic module protection device according to the embodiment of the present application is described below with reference to the accompanying drawings.

[0042] Figure 1 is a structural schematic diagram of a photovoltaic module protection device provided in an embodiment of the present application; Figure 2 is a partial enlarged view of point A in Figure 1; Figure 3 is a schematic diagram of a flexible protective member in a rolled-up state in the photovoltaic module protection device provided in an embodiment of the present application; Figure 4 is a partial enlarged view of point B in Figure 3.

[0043] 1-4 , the photovoltaic component protection device 100 according to the embodiment of the present application includes: a mounting frame 10 , a winding assembly 20 , a counterweight block 30 , and a trigger assembly 50 .

[0044] The mounting frame 10 includes a support platform 11 for carrying the photovoltaic assembly 40 and a stopper 12 connected to the support platform 11 .

[0045] The winding assembly 20 includes a driving rope 21 and a winding roller 22 wound with a flexible protective member 26. The winding roller 22 and the stopper 12 are connected to opposite sides of the support platform 11, and the driving rope 21 is at least partially located on the top side of the support platform 11 and its two ends are respectively connected to the counterweight 30 and the flexible protective member 26.

[0046] The trigger assembly 50 includes a clamping member 51 and a sensing plate 52 which are transmission-connected to each other. The clamping member 51 is connected to the counterweight 30 and the limiting member 12 respectively, and the sensing plate 52 is hinged to the counterweight 30 .

[0047] The induction plate 52 is configured to rotate when under pressure, and drive the clamping member 51 to disengage from the limiting member 12, so that the counterweight block 30 falls, and drives the flexible protective member 26 to unwind from the winding roller 22 and be stretched on the top side of the support platform 11 through the driving rope 21.

[0048] The clamping member 51 is respectively connected to the counterweight 30 and the stopper 12, and the clamping member 51 relatively fixes the counterweight 30 and the stopper 12. After the connection between the counterweight 30 and the stopper 12 is released, the counterweight 30 will fall toward the bottom of the support platform 11 under its own gravity.

[0049] Since the sensing plate 52 is hinged to the counterweight 30, the sensing plate 52 can rotate around its hinge axis when it is compressed. Since the clamping member 51 is in transmission connection with the sensing plate 52, the sensing plate 52 is configured to rotate when it is compressed, and drive the clamping member 51 to disengage from the limiting member 12, so that the counterweight 30 falls, and drive the flexible protective member 26 to unwind from the winding roller 22 and be stretched on the top side of the support platform 11 through the driving rope 21. Therefore, when the sensing plate 52 rotates, the clamping member 51 is driven to disengage from the limiting member 12, and the connection between the counterweight 30 and the limiting member 12 is released. The counterweight 30 falls toward the bottom of the support platform 11 under the action of gravity, thereby pulling the drive rope 21. Since the winding roller 22 and the limiter 12 are connected to the opposite sides of the support platform 11, at least part of the rope section of the drive rope 21 connected to the flexible protective member 26 is located on the top side of the support platform 11. The two ends of the drive rope 21 are respectively connected to the counterweight 30 and the flexible protective member 26. Therefore, after the drive rope 21 is pulled, the flexible protective member 26 will be gradually pulled to unwind from the winding roller 22 and move along the pulling direction of the drive rope 21, thereby being stretched on the top side of the support platform 11 to protect the photovoltaic module 40 on the top side of the support platform 11. When encountering extreme weather, if falling objects in the air, such as hail, fall on the induction plate 52, the induction plate 52 can be compressed and automatically respond. Compared with the prior art that relies on motor drive, there is no need to connect a power supply, and the protection reliability is higher.

[0050] In other words, the photovoltaic module protection device 100 of the embodiment of the present application adopts a purely mechanical structure design, which means that even in the event of a power outage, the device can still operate normally relying on its own mechanical power to ensure that the photovoltaic module 40 is protected in time in severe weather.

[0051] In the embodiment of the present application, referring to FIG. 4 , a through slot 31 is provided in the counterweight block 30 , and the angle between the extending direction of the through slot 31 and the gravity direction is less than 90 degrees, and the through slot 31 preferably extends along the gravity direction.

[0052] A first limiting groove 311 is opened on the groove wall of the through groove 31, and a second limiting groove 312 is opened on the outer surface of the limiting member 12 at a position corresponding to the first limiting groove 311. The two ends of the clamping member 51 are respectively located in the first limiting groove 311 and the second limiting groove 312, and the second limiting groove 312 has a preset distance from the bottom of the support platform 11.

[0053] Since the stopper 12 is inserted into the through slot 31, the stopper 12 and the through slot 31 have only a degree of freedom along the extension direction of the through slot 31, and the two ends of the clamping member 51 are respectively located in the first stopper 311 and the second stopper 312, and the relative direction of the first stopper 311 and the second stopper 312 has an angle with the extension direction of the through slot 31, and the clamping member 51 can respectively abut against at least one wall portion of the first stopper 311 and the second stopper 312 along the gravity direction, so that the stopper 12 and the counterweight 30 can be relatively fixed. Since the angle between the extension direction of the through slot 31 and the gravity direction is less than 90°, the second stopper 312 and the bottom of the support platform 11 have a preset spacing, so when the clamping member 51 is separated from the stopper 12, the counterweight 30 can fall downward along the stopper 12 under the action of gravity.

[0054] In the embodiment of the present application, referring to FIG1 , the limiting member 12 is constructed as a guide rail structure, and the limiting member 12 extends along the gravity direction. The second limiting groove 312 is located on a side of the limiting member 12 away from the bottom of the support platform 11 .

[0055] In this way, when the counterweight 30 falls, the stopper 12 can guide the counterweight 30 to prevent the counterweight 30 from falling outside the preset position. The second stopper 312 is located on the side of the stopper 12 away from the bottom of the support platform 11, which can make the counterweight 30 have a longer falling stroke.

[0056] In the embodiment of the present application, referring to FIG. 4 , the trigger assembly 50 further includes an elastic reset member 53 and a connecting member 54. The elastic reset member 53 is clamped between the first groove bottom wall of the first limiting groove 311 and the clamping member 51; the side of the clamping member 51 facing the elastic reset member 53 is connected to the induction plate 52 through the connecting member 54.

[0057] With such arrangement, when the induction plate 52 rotates around its own hinge axis, for example, when it rotates counterclockwise, it can apply a force toward the first groove bottom wall of the first limiting groove 311 to the clamping member 51, and the clamping member 51 moves toward the first groove bottom wall of the first limiting groove 311, and exits the second limiting groove 312, and the elastic reset member 53 is compressed, at which time the counterweight 30 will fall. After falling, if it needs to be reset, the counterweight 30 can be manually picked up and returned to the initial position, that is, the relative position of the notches of the first limiting groove 311 and the second limiting groove 312. At this time, the clamping member 51 can enter the second limiting groove 312 again under the elastic force of the elastic reset member 53, so as to achieve relative fixation of the counterweight 30 and the limiting member 12. In addition, the connecting member 54 can be a connecting rope.

[0058] In the embodiment of the present application, the induction plate 52 includes a main plate 521 and a transition plate 522 connected to each other, and the angle between the main plate 521 and the transition plate 522 is an obtuse angle. The transition plate 522 is hinged to the counterweight 30, and the end of the transition plate 522 away from the main plate 521 is connected to the connecting member 54.

[0059] Such an arrangement enables the main body plate 521 to be arranged perpendicular to the direction of gravity as much as possible, thereby providing a larger contact area with the falling object.

[0060] In the embodiment of the present application, an avoidance groove 32 is further provided at a position on the surface of the counterweight block 30 corresponding to the position of the induction plate 52. The induction plate 52 is hinged on the side groove wall of the avoidance groove 32. A connecting hole (not shown) is further provided on the bottom wall of the avoidance groove 32. One end of the connecting hole is connected to the avoidance groove 32, and the other end is connected to the first limit groove 311. The connecting member 54 is passed through the connecting hole.

[0061] Such arrangement can, on the one hand, prevent the induction plate 52 from interfering with the counterweight 30 when rotating, and on the other hand, enable the connecting member 54 to extend into the first limiting groove 311 .

[0062] In the embodiment of the present application, referring to FIG. 1 , the support platform 11 includes a support plate 111 and a support leg 112 disposed at the bottom of the support plate 111. The support plate 111 is arranged tilted relative to the direction of gravity;

[0063] The winding roller 22 and the limiting member 12 are both connected to the support plate 111 , and the setting height of the winding roller 22 is lower than the setting height of the limiting member 12 .

[0064] With such arrangement, the flexible protective member 26 can be opened from the lower side to the higher side of the photovoltaic assembly 40 when being unrolled.

[0065] In the embodiment of the present application, a fixed pulley 60 is further provided on the support plate 111 . The fixed pulley 60 is located on the top side of the limiting member 12 . The driving rope 21 is wound around the fixed pulley 60 and connected to the counterweight 30 .

[0066] Such arrangement can realize the steering of the driving rope 21, so that after the counterweight block 30 falls, it can pull one end of the flexible protective member 26 to unwind from bottom to top.

[0067] In the embodiment of the present application, the winding assembly 20 also includes a spring assembly, which includes a spring box 24 and a spring spring 25 , one end of the spring spring 25 is connected to the spring box 24 , and the other end of the spring spring 25 is connected to the winding roller 22 .

[0068] Such arrangement enables the flexible protective member 26 to be automatically reeled in under the elastic restoring force of the clockwork spring 25 after being unwound.

[0069] In the embodiment of the present application, the outer end of the flexible protective member 26 in the winding direction is connected to the connecting shaft 23 , the connecting shaft 23 extends along the axial direction of the winding roller 22 , and the driving rope 21 is connected to the connecting shaft 23 .

[0070] This makes it easier for the drive rope 21 to be pulled evenly over the entire width of the flexible protective member 26 .

[0071] The working process of the photovoltaic module protection device 100 of the present application is explained below in conjunction with Figures 1 to 4.

[0072] When the photovoltaic assembly is working normally, as shown in Figures 3 and 4, the two ends of the clamping member 51 are respectively located in the first limiting groove 311 and the second limiting groove 312, and the counterweight block 30 and the limiting member 12 are relatively fixed. At this time, the flexible protective member 26 is in a rolled-up state.

[0073] When encountering bad weather, the falling object hits the surface of the induction plate 52, and the induction plate 52 rotates counterclockwise, driving the clamping member 51 to move toward the elastic reset member 53 through the connecting member 54, and the clamping member 51 exits the second limiting groove 312 and enters the first limiting groove 311. At this time, the counterweight 30 falls to the ground. Referring to Figures 1 and 2, during the falling process of the counterweight 30, the driving rope 21 pulls the connecting shaft 23 to drive the flexible protective member 26 to unwind and block the top side of the photovoltaic module 40 to protect the photovoltaic module 40.

[0074] After the bad weather is over, the counterweight 30 is raised manually. During this process, under the action of the clockwork assembly, the flexible protective member 26 will also be wound onto the winding roller 22 until the counterweight 30 moves to the position shown in Figure 4. The notches of the first limit groove 311 and the second limit groove 312 are relative, and the partial structure of the clamping member 51 enters the second limit groove 312 under the elastic force of the elastic reset member 53. The counterweight and the limit member 12 are relatively fixed again, and the flexible protective member 26 is in a wound state.

[0075] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0076] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
