Abstract
Description
Technical Field
[0001] This utility model relates to the field of photovoltaic module technology, and in particular to an adaptable anti-clogging photovoltaic manifold water guiding and mud discharge clamp. Background Technology
[0002] The drainage and sludge removal device for photovoltaic modules is crucial for maintaining power generation efficiency. In existing technologies, such as the structure disclosed in Chinese Patent No. CN222868860U, an enhanced water-guiding and sludge-removing clamp for photovoltaic modules, drainage relies on "breaking water surface tension + siphon principle" through a snap-fit part, a fixed base, a water-guiding groove, and a water-guiding and sludge-removing port. However, this structure has the following significant drawbacks in practical applications:
[0003] Poor frame compatibility: The fixed base is a rigid structure that can only be used with photovoltaic aluminum frames of a single thickness. It cannot be used with photovoltaic module frames of different specifications of 20-40mm on the market, which leads to the need to customize the device for different projects, increasing procurement costs and inventory pressure.
[0004] The siphon start-up threshold is high: it relies on water accumulation to reach a certain height (such as 3mm) to trigger the siphon. Under low water conditions (such as dew or light rain), it cannot form effective drainage, resulting in water accumulation remaining on the surface of the module, which easily attracts dust and forms a "mud film" that blocks sunlight. Actual measurements show that this can lead to a 3%-5% decrease in power generation.
[0005] High risk of silt blockage: The water diversion channel is a smooth straight channel, which makes it easy for silt to accumulate at the bottom; the silt discharge outlet is just a regular opening without an active drainage structure, which is prone to blockage after long-term use and requires regular manual cleaning (2-3 times per year), increasing the cost of operation and maintenance by 15% per operation.
[0006] Installation and maintenance are inconvenient: The snap-fit part needs to be snapped on from the bottom of the component upwards. During installation, the component needs to be lifted or adjacent components need to be removed, resulting in low installation efficiency of new power plants (increased installation time for a single component). When replacing components in old power plants, the components need to be shut down, which affects power generation revenue.
[0007] In summary, existing technologies cannot meet the requirements for efficient and reliable operation of photovoltaic power plants under diverse frame specifications, complex weather conditions, and subsequent maintenance needs. There is an urgent need for an improved device with better compatibility, drainage efficiency, and anti-clogging capabilities. Utility Model Content
[0008] To address the shortcomings of existing technologies, this utility model provides an adaptable anti-clogging photovoltaic manifold water guiding and sludge discharge clamp, aiming to solve the above-mentioned problems.
[0009] To achieve the above objectives, this utility model provides the following technical solution: an adaptable anti-clogging photovoltaic (PV) water-conducting and sludge-discharging clamp, comprising an upper clamp body, a lower clamp body, a connecting component, and a water-conducting and sludge-discharging mechanism. The upper clamp body is connected to the lower clamp body via the connecting component. The upper clamp body has a sludge-discharging inlet and a sludge-discharging outlet, and also has several water-guiding holes. The sludge-discharging inlet and water-guiding holes are all connected to the sludge-discharging outlet. The connecting component is used to adjust the distance between the upper and lower clamp bodies to adapt to PV components of different sizes. One end of the water-conducting and sludge-discharging mechanism is connected to the side of the upper clamp body near the sludge-discharging outlet. The water-conducting and sludge-discharging mechanism is used to connect the sludge-discharging outlet, thereby increasing the sludge-water discharge speed and reducing sludge-water residue. Through the synergistic effect of the overall structure, the connecting component connects the upper and lower clamp bodies, achieving adaptive clamping of PV components of different sizes, significantly improving the sludge-water discharge speed and reducing sludge-water residue, thereby improving drainage efficiency, extending the maintenance cycle, and reducing operation and maintenance costs.
[0010] Furthermore, the connecting assembly includes a pullable compression spring, a pull ring head, and a bolt. The pull ring head is located at both ends of the pullable compression spring, and the upper and lower ends of the pullable compression spring are connected to the upper clamp and the lower clamp respectively through the pull ring head and the bolt.
[0011] Furthermore, the sludge discharge mechanism has a guide groove at one end near the sludge discharge outlet, and the sludge discharge mechanism is also provided with several micro-protrusions for connecting the guide groove. The guide groove is used to reduce the water flow starting resistance and guide the mud and water at the high point where the sludge discharge outlet is located to the low point. The micro-protrusions are used to gather the dispersed low water volume into a fine water flow.
[0012] Furthermore, the guide channel has a V-shaped opening design. The opening width of the guide channel near the sludge discharge outlet is 10mm, and the opening width of the end away from the sludge discharge outlet is 2mm. The inner wall of the guide channel is coated with polytetrafluoroethylene.
[0013] Furthermore, the micro-convex ridge is inclined at 15° along the direction of water flow.
[0014] Furthermore, the inner walls of the upper clamp and the lower clamp are both provided with silicone cushioning pads on the side closest to each other.
[0015] The beneficial effects of this utility model are:
[0016] 1. In this utility model, by setting a ground connection component to connect the upper clamp and the lower clamp, the overall structure works together to achieve adaptive clamping of photovoltaic components of different sizes, which significantly improves the mud and water discharge speed and reduces mud and water residue, thereby improving drainage efficiency, extending the maintenance cycle and reducing operation and maintenance costs.
[0017] 2. In this utility model, the ground connection component includes a pullable compression spring, a pull ring head, and a bolt. The pullable compression spring can adaptively adjust the distance between the upper and lower clamping bodies through its own elasticity, which not only simplifies the installation process and reduces the skill requirements for installers, but also provides a stable and uniform clamping force, effectively offsetting vibration and impact during operation, and enhancing the stability and safety of the overall structure.
[0018] 3. In this utility model, the ground-level sludge discharge mechanism is equipped with a guide channel and a micro-protruding ridge inclined at 15° along the water flow direction. The micro-protruding ridge gathers the dispersed low water volume into a fine water flow, and the guide channel reduces the water flow starting resistance. Together, they reduce the siphon trigger water level from the original 3mm to 0.8mm, realizing rapid and stable drainage under low water volume conditions. In addition, the guide channel adopts a V-shaped opening design and the inner wall is sprayed with a polytetrafluoroethylene superhydrophobic coating, which greatly reduces the adhesion of mud and sand, effectively extends the cleaning cycle, and significantly improves the anti-clogging performance.
[0019] 4. In this utility model, by setting silicone buffer pads on the inner walls of the ground clamp and the lower clamp, the friction with the photovoltaic frame is increased, avoiding wear on the frame, and improving the stability and safety of clamping. It has certain practical value and promotional value. Attached Figure Description

[0027] like Figure 1 , 2 As shown in Figure 3, an adaptable anti-clogging photovoltaic water-guiding and sludge-discharging clamp includes an upper clamp body 1, a lower clamp body 2, a connecting component 3, and a water-guiding and sludge-discharging mechanism 4. The upper clamp body 1 is connected to the lower clamp body 2 through the connecting component 3. The upper clamp body 1 has a sludge-discharging inlet 11 and a sludge-discharging outlet 12. The upper clamp body 1 also has several water-guiding holes 13. The sludge-discharging inlet 11 and the water-guiding holes 13 are all connected to the sludge-discharging outlet 12. The connecting component 3 is used to adjust the distance between the upper clamp body 1 and the lower clamp body 2 to adapt to photovoltaic components of different sizes. One end of the water-guiding and sludge-discharging mechanism 4 is connected to the side of the upper clamp body 1 near the sludge-discharging outlet 12. The water-guiding and sludge-discharging mechanism 4 is used to connect the sludge-discharging outlet 12 to increase the sludge-water discharge speed and reduce sludge-water residue.
[0028] In one embodiment, the connecting assembly 3 includes a pullable compression spring 31, a pull ring head 32, and a bolt 33. The pull ring head 32 is located at the upper and lower ends of the pullable compression spring 31. The upper and lower ends of the pullable compression spring 31 are connected to the upper clamping body 1 and the lower clamping body 2 respectively through the pull ring head 32 and the bolt 33. The connecting assembly 3 includes a pullable compression spring 31, a pull ring head 32, and a bolt 33. The distance between the upper clamping body 1 and the lower clamping body 2 is adaptively adjusted by the spring force, which not only simplifies the installation process and reduces the skill requirements for installers, but also provides a stable and uniform clamping force, effectively offsetting the vibration and impact during operation, and enhancing the stability and safety of the overall structure.
[0029] In one implementation, the sludge discharge mechanism 4 is provided with a guide groove 41 at one end near the sludge discharge outlet 12. The sludge discharge mechanism 4 is also provided with several micro-protrusions 42 for connecting the guide groove 41. The guide groove 41 is used to reduce the water flow starting resistance and guide the mud and water at the high place where the sludge discharge outlet 12 is located to the low place. The micro-protrusions 42 are used to gather the dispersed low water volume into a fine water flow.
[0030] As one implementation method, the guide channel 41 has a V-shaped opening design. The opening width of the guide channel 41 near the sludge discharge outlet 12 is 10mm, and the opening width of the end away from the sludge discharge outlet 12 is 2mm. Furthermore, the inner wall of the guide channel 41 is coated with a polytetrafluoroethylene coating. By spraying the polytetrafluoroethylene superhydrophobic coating, the adhesion of mud and sand is greatly reduced, the cleaning cycle is effectively extended, and the anti-clogging performance is significantly improved.
[0031] As one implementation, the micro-protrusion 42 is inclined at 15° along the direction of water flow.
[0032] As one implementation method, silicone buffer pads 5 are provided on the inner walls of the upper clamp 1 and the lower clamp 2 on the side that are close to each other. The silicone buffer pads 5 increase the friction between the upper clamp 1, the lower clamp 2 and the photovoltaic frame, avoid frame wear, and improve the stability and safety of clamping.
[0033] The working principle of this utility model is as follows: In use, the pullable compression spring 31 in the connecting assembly 3 connects the upper clamp 1 and the lower clamp 2 through the pull ring head 32 and bolt 33. The spring force makes the clamp adapt to photovoltaic frames of different thicknesses. The silicone buffer pad 5 increases friction and avoids frame wear. Rainwater or muddy water enters the device through the side mud discharge inlet 11 and several top water inlet holes 13 on the upper clamp 1, and gathers to the mud discharge outlet 12. The mud discharge mechanism 4 is connected to the mud discharge outlet 12. Its internal micro-protrusions 42 gather the dispersed low water volume into a fine water flow and guide it to the guide channel 41. The guide channel 41 has a V-shaped design and the inner wall is coated with polytetrafluoroethylene, which has superhydrophobic properties and effectively reduces mud and sand adhesion. The guide channel 41 guides the muddy water from high to low at a certain angle, reducing the water flow starting resistance. The micro-protrusions 42 are inclined at 15° along the water flow direction to further promote water flow convergence and guidance.
[0034] The entire process utilizes a "low-water-level siphon trigger" and a "self-cleaning and anti-clogging" mechanism to achieve the effect of draining small amounts of water and preventing sediment from accumulating, thus ensuring the cleanliness of the photovoltaic module surface and the power generation efficiency.
