Description

Technical Field

[0001] This utility model relates to the field of photovoltaic equipment technology, specifically to a photovoltaic mounting plate with a water collection structure. Background Technology

[0002] With the continuous development of science and technology, photovoltaic technology has made great progress, and a large number of photovoltaic devices have been put into use. Large-scale photovoltaic devices are generally installed in arid western regions with good sunshine conditions and sparse populations. Therefore, using photovoltaic devices for rainwater harvesting has become an effective way to solve water problems. Existing technologies usually collect rainwater from the surface of photovoltaic panels, but the amount of rainwater collected is relatively low. A large amount of rainwater flows to the ground through the gaps between the photovoltaic panels, and the rainwater flowing through the gaps between the photovoltaic panels accelerates the rusting of the photovoltaic panel wiring and the bolts that install the water collection structure, increasing the frequency of maintenance by maintenance personnel. Utility Model Content

[0003] To address the aforementioned technical shortcomings, the purpose of this utility model is to provide a photovoltaic mounting panel with a water collection structure, including a support frame and a mounting bracket rotatably mounted on the support frame. Photovoltaic panels are arranged in a matrix on the mounting bracket. A linear actuator for driving the mounting bracket to rotate is provided on the support frame. Several diversion plates are provided on the mounting bracket, arranged parallel to the photovoltaic panels, with the sidewalls of the diversion plates adhering to the sidewalls of the photovoltaic panels. A water collection channel is provided at the bottom of the mounting bracket, with the bottom ends of the diversion plates located above the water collection channel. The water collection channel extends horizontally along the arrangement direction of the support frame. A guide slope inclined from both ends towards the center is provided within the water collection channel. A water outlet pipe is provided at the lowest point of the center of the guide slope, and the water outlet pipe connects to a water collection tank located on the support frame.

[0004] To ensure that the installation positions of the diversion plate and the water collection channel can effectively collect rainwater, the following features are specifically designed: the diversion plate is provided with several mounting holes, and the diversion plate is fixedly connected to the mounting frame by mounting bolts and nuts through the mounting holes; the diversion plate is provided with raised side baffles on both sides; and a water baffle is provided at the end of the water collection channel away from the diversion plate, with the top of the water baffle being higher than the bottom of the diversion plate.

[0005] To prevent rainwater flowing inside the diversion plate from corroding and rusting the bolts fixing the diversion plate, the following features are specifically provided: a protruding block is provided on the periphery of the mounting hole of the diversion plate, the protruding block protrudes from the surface of the diversion plate, a number of insertion holes are provided on the top of the protruding block, and a sealing cover is installed on the top of the protruding block. The sealing cover is inserted into the insertion hole through an insertion post corresponding to the insertion hole and fits against the opening on the top of the protruding block.

[0006] To prevent rainwater falling directly on the sealing cover from flowing to the joint between the sealing cover and the protrusion, the following feature is specifically provided: the periphery of the sealing cover protrudes from the periphery of the protrusion.

[0007] To address the issue that when rainfall is heavy, the water level inside the diversion plate may exceed the top of the raised block, causing rainwater to enter the raised block through the gap between the raised block and the sealing cover. The following features are incorporated: the diversion plate has several trickle channels located on the upper side of the raised block. These trickle channels gradually narrow towards one end of the raised block, and the output end of each trickle channel is lower than the height of the raised block.

[0008] To prevent rainwater from flowing from the top of the trickle channel to the protrusion due to a high water level in the trickle channel, the following features are specifically designed: the top of the trickle channel is provided with several overflow channels extending along the length of the trickle channel, and the total cross-sectional area of ​​the overflow channels is greater than the opening area of ​​the output end of the trickle channel; the overflow channels extend to the end of the protrusion near the water collection channel.

[0009] To prevent impurities from clogging the water outlet pipe, the following features are specifically designed: a filter box is installed inside the water collection channel, located above the output end of the water outlet pipe, and filter holes are provided at both ends and the top of the filter box facing the guide slope.

[0010] To ensure that the water outlet pipe remains connected to the water collection tank when the mounting bracket is tilted to any angle, the following feature is specifically provided: the water outlet pipe is a flexible corrugated pipe.

[0011] The advantages of this utility model compared to the prior art are: Firstly, this invention increases the efficiency of rainwater collection by using several diversion plates, and seals the gaps between photovoltaic panels by attaching them to the sidewalls of the photovoltaic panels, ensuring that rainwater can only contact the surface of the diversion plates and the surface of the photovoltaic panels. This not only improves the efficiency of rainwater collection, but also prevents rainwater from directly contacting components such as wires below the photovoltaic panels.

[0012] Secondly, the diversion plate of this utility model is installed on the mounting frame with bolts and nuts. The mounting hole of the diversion plate is located inside the protrusion. The top of the protrusion is sealed with a sealing cover. The rainwater guided by the diversion plate first passes through the trickle channel and then contacts the protrusion. The output end of the trickle channel is lower than the height of the protrusion. Therefore, the rainwater passing through the trickle channel is always lower than the height of the protrusion, so it will not contact the joint between the protrusion and the sealing cover. This avoids the rainwater directly contacting the bolts, causing the bolts to rust and affecting the positional stability of the diversion plate, and also reduces the number of maintenance personnel.

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figures 1 to 7 : A photovoltaic mounting panel with a water collection structure includes a support frame 1 and a mounting frame 1a rotatably mounted on the support frame 1. The photovoltaic panels are distributed in a matrix on the mounting frame 1a. A linear actuator 1b for driving the mounting frame 1a to rotate is provided on the support frame 1. Several diversion plates 2 are provided on the mounting frame 1a. The diversion plates 2 are arranged parallel to the photovoltaic panels. The sidewalls of the diversion plates 2 are attached to the sidewalls of the photovoltaic panels. A water collection channel 3 is provided at the bottom of the mounting frame 1a. The bottom end of the diversion plates 2 is located above the water collection channel 3. The water collection channel 3 extends horizontally along the arrangement direction of the support frame 1. A guide slope 3a is provided in the water collection channel 3, which is inclined from both ends to the center. A water outlet pipe 3b is provided at the lowest point of the center of the guide slope 3a. The water outlet pipe 3b is connected to a water collection tank 4 located on the support frame 1.

[0024] In this application, photovoltaic panels are matrix-mounted on mounting frame 1a. Mounting frame 1a is rotatably mounted on support frame 1, and its tilt angle is changed by the working end of linear actuator 1b, thereby adapting to the position of the sun and ensuring the working efficiency of the photovoltaic panels. Linear actuator 1b can be a cylinder, hydraulic cylinder, or electric push rod, etc. Mounting frame 1a is also provided with drainage plates 2 arranged parallel to the photovoltaic panels. The drainage plates 2 can be located on both sides of the photovoltaic panels to increase the contact area with rainwater, and the drainage plates 2 follow the rotation of mounting frame 1a to maintain the same tilt angle as the photovoltaic panels. In rainy weather, the drainage plates 2 can collect rainwater and guide it to the water collection channel 3 at the bottom of mounting frame 1a. The water collection channel 3 extends horizontally along the arrangement direction of support frame 1. Rainwater collected along the surface of photovoltaic panels and the surface of drainage plates 2 falls into the water collection channel 3 and converges along the guide slope 3a of the water collection channel 3 to the outlet pipe 3b in the middle of the water collection channel 3. The outlet pipe 3b transports the rainwater to the water collection tank 4 for storage, which is convenient for subsequent use. In this embodiment, several diversion plates 2 are used to increase the efficiency of rainwater collection. By attaching them to the sidewalls of the photovoltaic panels, the gaps between the photovoltaic panels are sealed, ensuring that rainwater can only come into contact with the surface of the diversion plates 2 and the surface of the photovoltaic panels. This not only improves the efficiency of rainwater collection but also prevents rainwater from directly contacting components such as wires below the photovoltaic panels.

[0025] To ensure that the installation positions of the diversion plate 2 and the water collection channel 3 can effectively collect rainwater, the following features are specifically designed: The diversion plate 2 is provided with several mounting holes 2a. The diversion plate 2 is fixedly connected to the mounting frame 1a by mounting bolts 2b and nuts 2b1 through the mounting holes 2a. The diversion plate 2 is provided with raised side baffles 2c on both sides. The end of the water collection channel 3 away from the diversion plate 2 is provided with a baffle plate 3c. The top of the baffle plate 3c is higher than the bottom of the diversion plate 2.

[0026] like Figure 6 and Figure 7As shown, in this embodiment, the diversion plate 2 is installed on the mounting bracket 1a by bolts 2b and nuts 2b1 to ensure that the position of the diversion plate 2 and the photovoltaic panel is fixed. The bottom end of the diversion plate 2 is located on the upper side of the water collection channel 3. The water flow guided by the diversion plate 2 and the side baffle 2c is affected by gravity and has a certain initial velocity when it leaves the diversion plate 2. Therefore, the water flow will come into contact with the baffle 3c on the side of the water collection channel 3 away from the diversion plate 2 and fall into the water collection channel 3 under the guidance of the baffle 3c and flow along the guide slope 3a to the outlet pipe 3b. The height of the baffle 3c is higher than the bottom end of the diversion plate 2 to ensure that the baffle 3c blocks the water flow guided by the diversion plate 2. The water collection channel 3 can be tilted and expanded outward to the side away from the diversion plate 2, thereby increasing the collection area of ​​rainwater.

[0027] To prevent rainwater flowing inside the drainage plate 2 from corroding and rusting the bolts 2b that fix the drainage plate 2, the following features are specifically provided: The drainage plate 2 is provided with a protrusion 2a1 on the periphery of the mounting hole 2a. The protrusion 2a1 protrudes from the surface of the drainage plate 2. The top of the protrusion 2a1 is provided with several insertion holes 2a2. A sealing cover 2a3 is installed on the top of the protrusion 2a1. The sealing cover 2a3 is inserted into the insertion hole 2a2 through the insertion post 2a4 corresponding to the insertion hole 2a2 and fits against the top opening of the protrusion 2a1.

[0028] like Figure 2 , Figure 6 and Figure 7 As shown, in this embodiment, the mounting hole 2a of the diversion plate 2 is located inside the protrusion 2a1, and the bolt 2b is installed inside the protrusion 2a1. The top of the protrusion 2a1 is sealed by the sealing cover 2a3. Therefore, when rainwater enters the diversion plate 2 and flows along the diversion plate 2, the rainwater will move along the outer wall of the protrusion 2a1 and the outer wall of the sealing cover 2a3, so that it will not directly contact the bolt 2b located inside the protrusion 2a1. This avoids the rainwater directly contacting the bolt 2b, causing the bolt 2b to rust and affecting the positional stability of the diversion plate 2, and also reduces the number of maintenance personnel.

[0029] To prevent rainwater falling directly on the sealing cover 2a3 from flowing to the joint between the sealing cover 2a3 and the protrusion 2a1, the following features are specifically provided: The periphery of the sealing cover 2a3 protrudes beyond the periphery of the protrusion 2a1.

[0030] like Figure 2 , Figure 6 and Figure 7 As shown, in this embodiment, when rainwater falls directly onto the sealing cover 2a3, it will flow along the inclined surface of the sealing cover 2a3. The periphery of the sealing cover 2a3 protrudes from the periphery of the protrusion 2a1 to prevent water from flowing back to the joint between the protrusion 2a1 and the sealing cover 2a3.

[0031] To address the issue that when rainfall is heavy and the water level in the diversion plate 2 is higher than the top of the protrusion 2a1, causing rainwater to enter the protrusion 2a1 through the gap between the protrusion 2a1 and the sealing cover 2a3, the following features are specifically designed: The diversion plate 2 is provided with several trickle channels 2d, which are located on the upper side of the protrusion 2a1. The trickle channels 2d gradually narrow towards one end of the protrusion 2a1, and the height of the output end of the trickle channel 2d is lower than the height of the protrusion 2a1.

[0032] like Figure 7 As shown, in this embodiment, the diversion plate 2 is provided with a trickle channel 2d located on the upper side of the protrusion 2a1. The rainwater guided by the diversion plate 2 first passes through the trickle channel 2d and then contacts the protrusion 2a1. The height of the output end of the trickle channel 2d is lower than the height of the protrusion 2a1. Therefore, the rainwater passing through the trickle channel 2d is always lower than the height of the protrusion 2a1, so it will not contact the joint between the protrusion 2a1 and the sealing cover 2a3. Since the diversion plate 2 in this embodiment is provided with several trickle channels 2d, the rainwater can be suppressed in segments, and the bolts 2b at each mounting hole 2a can be protected to prevent the water flow from contacting the joint between the protrusion 2a1 and the sealing cover 2a3.

[0033] To prevent rainwater from flowing from the top side of the trickle channel 2d to the protrusion 2a1 due to a high water level within the trickle channel 2d, the following features are specifically designed: The top of the trickle channel 2d is provided with several overflow channels 2d1 extending along the length of the trickle channel 2d. The total cross-sectional area of ​​the overflow channels 2d1 is greater than the opening area of ​​the output end of the trickle channel 2d. The overflow channels 2d1 extend to one end of the protrusion 2a1 near the water collection channel 3.

[0034] like Figure 7 As shown, in this embodiment, since the output end area of ​​the trickle channel 2d is smaller than the input end of the trickle channel 2d, rainwater will accumulate in the trickle channel 2d. When the water level in the trickle channel 2d is higher than the top of the trickle channel 2d and overflows, the rainwater will preferentially contact the overflow channel 2d1 set at the top of the trickle channel 2d and flow along the overflow channel 2d1 to the position of the diversion plate 2 below the protrusion 2a1, thereby avoiding the protrusion 2a1 and preventing the rainwater from contacting the gap between the protrusion 2a1 and the sealing cover 2a3. Since the total cross-sectional area of ​​the overflow channel 2d1 is larger than the output end opening area of ​​the trickle channel 2d, the flow rate of rainwater in the overflow channel 2d1 is greater than the flow rate in the trickle channel 2d, thereby alleviating the accumulation of rainwater in the trickle channel 2d.

[0035] To prevent impurities from clogging the water outlet pipe 3b, the following features are specifically designed: A filter box 3b1 is installed inside the water collection channel 3, located above the output end of the water outlet pipe 3b. The filter box 3b1 has filter holes at both ends and the top facing the guide slope 3a.

[0036] In this embodiment, rainwater that is guided and collected above the outlet pipe 3b by the guide slope 3a, as well as rainwater that directly enters the water collection channel 3, is filtered through the outlet pipe 3b to ensure the smooth flow of rainwater from the outlet pipe 3b to the water collection tank 4.

[0037] To ensure that the water outlet pipe 3b remains connected to the water collection tank 4 when the mounting bracket 1a is tilted to any angle, the following features are specifically designed: The outlet pipe 3b is a flexible corrugated pipe.

[0038] In this embodiment, the outlet pipe 3b is a flexible corrugated pipe, so it can be stretched to adapt to the height change of the water collection channel 3 when the mounting frame 1a is tilted, so as to ensure that the rainwater collected in the water collection channel 3 is transported into the water collection tank 4.

[0039] Working principle: During rainy weather, rainwater falls along the surface of the photovoltaic panel and the surface of the diversion plate 2 into the water collection channel 3, and flows along the guide slope 3a of the water collection channel 3 to the outlet pipe 3b in the middle of the water collection channel 3. The outlet pipe 3b transports the rainwater to the water collection tank 4 for storage. The diversion plate 2 is installed on the mounting bracket 1a by bolts 2b and nuts 2b1. The mounting holes 2a of the mounting bolts 2b are located inside the protrusion 2a1. When rainwater enters the diversion plate 2 and flows along the diversion plate 2, the rainwater first flows through a trickle... When channel 2d contacts the protrusion 2a1 again, the height of the output end of the trickle channel 2d is lower than the height of the protrusion 2a1. Therefore, the rainwater passing through the trickle channel 2d will move along the outer wall of the protrusion 2a1 and the outer wall of the sealing cover 2a3, and will not contact the joint between the protrusion 2a1 and the sealing cover 2a3. The rainwater falling directly on the sealing cover 2a3 will flow along the inclined surface of the sealing cover 2a3, thereby avoiding the rainwater directly contacting the bolt 2b and causing the bolt 2b to rust, which would affect the positional stability of the diversion plate 2.

[0040] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
