Abstract
Description
Technical field
[0001] The utility model belongs to the technical field of photovoltaics, and in particular relates to a photovoltaic drainage technology. [Background Technology]
[0002] PV sunrooms are all waterproof, with drainage gutters installed between the panels. Water from these gutters drains outside through conventional funnels and downspouts. Conventional drainage structures don't account for blockages. If leaves, sand, or dust clog the gutters and drain pipes, and if it rains, drainage becomes disrupted, overflowing the gutters can easily occur, flowing through the gaps between the panels onto the roof, causing leaks. Because sunrooms are typically seamless and extend beyond the eaves, maintenance and desilting require manual dredging, which is extremely risky. Alternatively, the original drainage system can be dismantled and replaced, resulting in high maintenance and desilting costs. [Utility Model Content]
[0003] In view of the shortcomings of the existing technology, the technical problem to be solved by the present invention is to provide a photovoltaic power station and its drainage and dredging structure to solve the leakage problem caused by the accumulation of silt and other dirt in the roof photovoltaic power station drainage system.
[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:
[0005] On the one hand, a photovoltaic power station drainage and dredging structure is provided, comprising an inclined water guide trough, a funnel connected to the obliquely lower end of the water guide trough, and a drainage pipe connected to the leakage hole at the bottom of the funnel, wherein a dredging hole is provided on the side wall of the funnel, and the dredging hole is detachably connected to a hole cover.
[0006] Preferably, the funnel is an inverted rectangular frustum structure.
[0007] Preferably, the bottom of the funnel is an inverted rectangular frustum structure, and the leakage hole is arranged at the bottom center of the funnel.
[0008] Preferably, the silt clearing hole extends outward perpendicularly to the side wall of the funnel; and / or, the silt clearing hole is a circular hole with a diameter greater than half the width of the side wall of the funnel.
[0009] Preferably, the water funnel is a stamped component; and / or the water funnel is made of aluminum alloy or stainless steel.
[0010] Preferably, a water drop hole is provided at the bottom of the obliquely downward end of the water guide trough, and a fixed lip connected to the water drop hole is provided at the upper opening of the funnel.
[0011] Preferably, the fixed lip overlaps the upper edge of the drain hole.
[0012] Preferably, a self-tapping screw is provided between the fixed lip and the upper edge of the drain hole.
[0013] Preferably, the fixed lip is fixed to the drain hole by gluing; and / or the bottom surface of the fixed lip is provided with friction lines.
[0014] On the other hand, a photovoltaic power station is provided, comprising a photovoltaic bracket and a photovoltaic module mounted on the photovoltaic bracket, and also comprising the drainage and dredging structure, wherein the water guide trough is provided between two longitudinally adjacent photovoltaic modules.
[0015] The utility model adopts the above technical solution, which has the following beneficial effects:
[0016] 1. The drainage and desilting structure of the present invention allows water to flow from the water channel to the funnel and then be discharged from the drain pipe, which can meet the normal drainage function when in use. The funnel has a large volume but a small drainage hole, so some leaves, mud, dust and other dirt that cannot be drained away accumulate in the funnel. After long-term use, the dirt is likely to clog the drainage channel. However, since the side wall of the funnel is provided with a desilting hole, the desilting hole is detachably connected to a hole cover. In this way, if silt blockage occurs later, it is only necessary to open the reserved desilting hole cover and desilt the roof photovoltaic array through the desilting hole. Therefore, the later desilting work does not need to be carried out above the array, nor does it need to dismantle the original drainage system.
[0017] The purpose of installing dredging holes on the side walls of the funnel is to facilitate dredging beneath the rooftop photovoltaic array. If the height is not too high, workers can simply stand and operate. If the height is much higher than the roof, a safety ladder can be set up on the rooftop to operate. Therefore, dredging work is convenient and safe, greatly improving the efficiency of dredging and reducing operation and maintenance expenses, while also significantly reducing the risks of dredging and operation.
[0018] 2. Since the abdominal cavity of the funnel is a rectangular cone structure, drainage can be smoother;
[0019] In addition, by forming a slope on the side wall of the bottom of the funnel and increasing the inclination angle, an inverted rectangular frustum structure is also formed. In this way, when draining water, a siphon effect will be generated when the water flows through the design structure, increasing the water flow rate and giving the funnel a self-cleaning function.
[0020] 3. Since the silt removal hole extends outward from the side wall of the funnel, it is convenient to connect with the hole cover and open the hole cover later to carry out silt removal work;
[0021] In addition, the dredging hole is designed to be a circular hole with a diameter greater than half the width of the side wall of the funnel in order to make the aperture of the dredging hole large enough to facilitate dredging work.
[0022] 4. The funnel can be made of lightweight metal materials, such as aluminum alloy / stainless steel stamping, which has high strength and corrosion resistance. It can not only increase the service life (up to 25 years) and achieve one-time installation to meet the functions of the entire life cycle; but also can use mold stamping for mass production to reduce manufacturing costs.
[0023] In addition, since the water guide trough is usually made of stamped aluminum alloy / stainless steel, the colors of the two can be consistent, which is more beautiful.
[0024] 5. The upper opening of the funnel is connected to the drain hole with a fixed lip. When installing, the bottom of the funnel is at the bottom, and it passes through the drain hole from top to bottom. Finally, the fixed lip is overlapped with the upper edge of the drain hole for easy and quick assembly and fixation.
[0025] 6. The fixing lip and the upper edge of the drain hole are fixed with self-tapping screws, which makes the fixation convenient and reliable. Of course, you can also fix it with glue at the same time to make it more tightly fixed to the bottom of the water channel.
[0026] In addition, since the bottom surface of the fixed lip is provided with friction grooves as a further anti-slip design, the friction between the funnel and the water guide groove is increased, thereby enhancing the connection reliability.
[0027] These features and advantages of the present invention will be disclosed in detail in the following specific embodiments and drawings.

[0034] The following is an explanation and description of the technical solutions of the embodiments of the present invention in conjunction with the drawings of the embodiments of the present invention, but the following embodiments are only preferred embodiments of the present invention and are not exhaustive. Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.
[0035] Those skilled in the art will appreciate that, unless there is any conflict, the features in the following embodiments and implementations may be combined with each other.
[0036] The terms used in this utility model are for the purpose of describing specific embodiments only and are not intended to limit the utility model. For example, the terms "upper," "lower," "horizontal," and "vertical" used below to indicate orientation or positional relationships are based solely on the orientation or positional relationships shown in the accompanying drawings and are used solely to facilitate the description of the utility model and simplify the description. They do not indicate or imply that the device or element referred to must have a specific orientation or be constructed or operated in a specific orientation. Therefore, they should not be construed as limiting the utility model.
[0037] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.
[0038] The photovoltaic sunroom installed on the roof of the existing technology also serves as a photovoltaic power station. The photovoltaic power station includes a photovoltaic bracket and photovoltaic modules installed on the photovoltaic bracket. Several photovoltaic modules are arranged in a rectangular array. In addition, a conventional drainage system is also provided, including a water guide trough. Water guide troughs are set under adjacent parts of two adjacent rows of photovoltaic modules in the horizontal direction for drainage. The water guide troughs extend longitudinally, are supported on the main beam and are installed at an angle.
[0039] Reference Figures 1 to 4 As shown, the photovoltaic power station drainage and desilting structure in this embodiment is designed to address the leakage problem caused by silt accumulation in existing drainage systems. It comprises an inclined water channel 2, a funnel 1 connected to the diagonally downward end of the channel 2, and a drain pipe 3 connected to a leakage hole 15 at the bottom of the funnel. The sidewall of the funnel 1 is provided with a desilting hole 12, which is detachably connected to a hole cover 13.
[0040] The drainage and desilting structure of the present invention allows water to flow from the water channel to the funnel and then be discharged from the drain pipe, which can meet the normal drainage function when in use. The funnel has a large volume but a small drainage hole, so some leaves, mud, dust and other dirt that cannot be drained away accumulate in the funnel. After long-term use, the dirt is likely to clog the drainage channel. However, since the side wall of the funnel is provided with a desilting hole, the desilting hole is detachably connected to a hole cover. In this way, if silt blockage occurs later, it is only necessary to open the reserved desilting hole cover and perform desilting work under the roof photovoltaic array through the desilting hole. Therefore, the later desilting work does not need to be performed above the array, nor does it need to dismantle the original drainage system.
[0041] The purpose of installing dredging holes on the side walls of the funnel is to facilitate dredging beneath the rooftop photovoltaic array. If the height is not too high, workers can simply stand and operate. If the height is much higher than the roof, a safety ladder can be set up on the rooftop to operate. Therefore, dredging work is convenient and safe, greatly improving the efficiency of dredging and reducing operation and maintenance expenses, while also significantly reducing the risks of dredging and operation.
[0042] Specifically, the funnel 1 is an inverted rectangular frustum structure. The bottom 14 of the funnel is also an inverted rectangular frustum structure, and the drainage hole 15 is located at the center of the bottom of the funnel 1. Because the funnel's abdominal cavity is an overall rectangular frustum structure, drainage is smoother. Furthermore, by forming an inclined surface on the sidewall of the bottom of the funnel, increasing the inclination angle, an inverted rectangular frustum structure is also formed. This design creates a siphon effect when water flows through this structure during drainage, increasing the water flow rate and giving the funnel a self-cleaning function.
[0043] Furthermore, the dredging hole 12 extends outward perpendicularly from the sidewall of the funnel. It is a circular hole with a diameter greater than half the width of the sidewall of the funnel. Since the dredging hole 12 extends outward from the sidewall of the funnel, it is convenient to connect it to the hole cover and later open the hole cover to carry out dredging. Furthermore, the dredging hole is designed as a circular hole with a diameter greater than half the width of the sidewall of the funnel to ensure that the hole diameter is large enough to facilitate dredging.
[0044] Preferably, the funnel 1 is a stamped component made of aluminum alloy or stainless steel. The funnel can be made of lightweight metal materials, such as stamped aluminum alloy or stainless steel, which offers high strength and corrosion resistance. This not only increases the service life (up to 25 years), enabling a single installation and full lifecycle functionality, but also allows for mass production using mold stamping to reduce manufacturing costs. Furthermore, since the water channel 2 is typically stamped from aluminum alloy or stainless steel, the colors of the two can be consistent, enhancing the aesthetics.
[0045] To connect the funnel to the gutter, a drain hole 21 is provided at the bottom of the gutter 2, obliquely facing downward. The upper opening of the funnel 1 is provided with a fixed lip 11 connected to the drain hole 21. The fixed lip 11 overlaps the upper edge of the drain hole 21. Furthermore, self-tapping screws are provided between the fixed lip 11 and the upper edge of the drain hole 21. The fixed lip 11 can also be glued to the drain hole 21. Furthermore, the bottom surface of the fixed lip 11 is provided with friction grooves to increase friction. During installation, the funnel is placed with the bottom at the bottom, passed through the drain hole from top to bottom, and finally the fixed lip is overlapped with the upper edge of the drain hole, making it easy to quickly assemble and secure. Gluing can also be applied simultaneously for a tighter fixation to the bottom of the gutter. Furthermore, the friction grooves on the bottom surface of the fixed lip serve as a further anti-slip feature, increasing friction between the funnel and the gutter and enhancing connection reliability.
[0046] The above description is merely a specific embodiment of the utility model, but the scope of protection of the utility model is not limited thereto. Those skilled in the art will understand that the utility model includes, but is not limited to, the contents described in the drawings and the above specific embodiments. Any modifications that do not deviate from the functional and structural principles of the utility model are intended to be included within the scope of the claims.
