Description

Technical Field

[0001] This application relates to the technical field of drainage, and particularly to a drainage trough for photovoltaic panels. Background Art

[0002] During the operation of a photovoltaic system, the main function of a drainage trough for photovoltaic panels is to timely and effectively drain the rainwater on the surface of the photovoltaic panels, preventing the rainwater from accumulating on the surface of the photovoltaic panels, thereby ensuring the normal power generation efficiency and service life of the photovoltaic panels.

[0003] However, the current drainage troughs for photovoltaic panels have relatively obvious defects. Since photovoltaic panels are mostly in an open-air environment, leaves, branches and other sundries of surrounding trees and other vegetation are extremely likely to fall on the surface of the photovoltaic panels under the influence of wind, self-growth or external factors. These sundries will flow into the drainage trough together with the rainwater. When a large amount of leaves and branches enter the drainage trough, it will cause blockage in the drainage trough, thus hindering the normal flow of rainwater and significantly reducing the drainage speed.

[0004] To solve this problem, this application proposes a drainage trough for photovoltaic panels. Utility Model Content

[0005] The purpose of this application is to propose a drainage trough for photovoltaic panels in view of the technical problems pointed out in the background art.

[0006] The technical solution of this application: A drainage trough for photovoltaic panels includes two groups of drainage troughs, and a group of anti-blocking mechanisms are respectively arranged in the two groups of drainage troughs;

[0007] The anti-blocking mechanism includes:

[0008] A drive shaft, with a guiding spiral blade installed on its outer side, and a transmission wheel installed at one end;

[0009] A driven wheel is arranged above the transmission wheel, and the driven wheel is connected to the transmission wheel through a transmission belt;

[0010] A rotating plate located above the guiding spiral blade, a driven shaft is installed in the middle of the rotating plate, and one end of the driven shaft is connected to the driven wheel. A group of side teeth are respectively installed on the front and rear sides of the rotating plate;

[0011] Two groups of fixed teeth are arranged on the inner wall of the drainage trough, and the side teeth and the fixed teeth are alternately distributed.

[0012] Preferably, a plurality of flow-accumulating troughs are obliquely installed above the drainage trough;

[0013] The drainage trough is open upward.

[0014] Preferably, the upper and lower plate surfaces of the rotating plate are both arc surface structures bulging in the middle.

[0015] Preferably, the two groups of fixed teeth are respectively installed on the front and rear sides of the rotating plate, and the rear ends thereof are fixed to the inner wall of the drainage groove.

[0016] Preferably, a discharge port is provided below the side of the drainage groove away from the drive box.

[0017] Preferably, the two drainage grooves are connected by a drive box, and a drive mechanism is provided in the drive box. The drive mechanism includes:

[0018] A drive motor, the output shaft of the drive motor is connected with a driving bevel gear;

[0019] Above the driving bevel gear, two driven bevel gears are meshed, and the driven bevel gears are connected with the two drive shafts.

[0020] Preferably, a first bearing is installed on the side of the discharge groove away from the drive box, and the side of the drive shaft away from the drive box is connected to the inner side of the first bearing;

[0021] Both ends of the driven shaft are installed with second bearings, and the second bearings are respectively installed on the left and right sides inside the drainage groove.

[0022] Compared with the prior art, the present application has the following beneficial technical effects:

[0023] By designing an anti-blocking mechanism, before rainwater and sundries such as branches and leaves enter the inside of the drainage groove, the sundries such as branches and leaves can be crushed, and the sundries with a larger volume are crushed into a smaller volume, so as to be fully mixed with the rainwater. During the conveying process, the sundries with a smaller volume can be smoothly pushed along with the water flow.

[0024] When the crushed sundries and rainwater fall into the drainage groove together, under the action of the discharge spiral blade, the water and sundries form a mixture and are spirally discharged from the drainage groove. Such a design avoids the problem of blockage inside the drainage groove caused by the accumulation of sundries, ensures the smoothness of the drainage groove, and improves the drainage efficiency.

[0033] Embodiment

[0034] As Figures 1-4 shown, a photovoltaic panel drainage trough 2 proposed by the present application includes two groups of drainage troughs 2, and a group of anti-blocking mechanisms 5 are respectively arranged in the two groups of drainage troughs 2; the anti-blocking mechanism 5 includes: a drive shaft 51, on the outer side of which a guiding spiral blade 52 is arranged, and a driving wheel 53 is arranged at one end; a driven wheel 54 is arranged above the driving wheel 53, and the driven wheel 54 is connected with the driving wheel 53 through a transmission belt 55; the driving wheel 53 can transmit power to the driven wheel 54 through the transmission belt 55, a rotating plate 56 located above the guiding spiral blade 52, a driven shaft 59 is installed in the middle of the rotating plate 56, and one end of the driven shaft 59 is connected with the driven wheel 54, and a group of side teeth 57 are respectively installed on the front and rear sides of the rotating plate 56; two groups of fixed teeth 58 are arranged on the inner wall of the drainage trough 2, and the side teeth 57 and the fixed teeth 58 are arranged in an interlaced manner. The interlaced distribution design can facilitate the crushing of larger branches and leaves and other sundries passing between them.

[0035] A plurality of converging troughs 1 are obliquely installed above the drainage trough 2; the drainage trough 2 is open upward. The rainwater on the surface of the photovoltaic panel can enter the drainage trough 2 along the path of the converging trough 1.

[0036] The upper and lower plate surfaces of the rotating plate 56 are both arc surface structures bulging in the middle. Water and branches and leaves and other sundries will flow to both sides of the rotating plate 56 under the action of gravity and the guidance of the arc surface.

[0037] Two sets of fixed teeth 58 are respectively installed on the front and rear sides of the rotating plate 56, and the rear ends thereof are fixed to the inner wall of the drainage groove 2.

[0038] A discharge port 4 is provided below the side of the drainage groove 2 away from the drive box 3. The rainwater and sundries entering the interior of the discharge groove 2 can be discharged outwards through the discharge port.

[0039] The two sets of drainage grooves 2 are connected by a drive box 3, and a drive mechanism is provided inside the drive box 3. The drive mechanism includes:

[0040] A drive motor 31, and the output shaft of the drive motor 31 is connected with a driving bevel gear 32;

[0041] Two driven bevel gears 33 are meshed above the driving bevel gear 32, and the driven bevel gears 33 are connected with two sets of drive shafts 51. The drive motor 31 can drive the driven bevel gears 33 to rotate through the driving bevel gear 32, and this gear transmission method can achieve efficient power transmission.

[0042] A first bearing 511 is installed on the side of the discharge groove away from the drive box 3, and the side of the drive shaft 51 away from the drive box 3 is connected to the inner side of the first bearing 511. During the rotation of the drive shaft 51, it can drive the inner side of the second bearing 511 to rotate, so that the drive shaft 51 can maintain an accurate axial position during rotation;

[0043] Both ends of the driven shaft 59 are installed with second bearings 512, and the second bearings 512 are respectively installed on the left and right sides inside the drainage groove 2. The design of the second bearing 51 enables the driven shaft 59 to maintain an accurate axial position during rotation.

[0044] The working principle of this embodiment is as follows:

[0045] Before use, the converging groove 1 is installed below the gap between the photovoltaic panels. The rainwater formed on the surface of the photovoltaic panels due to precipitation can smoothly flow into the converging groove 1 through these gaps and then enter the drainage groove 2. When the rainwater and sundries such as branches and leaves therein enter the interior of the drainage groove 2, during use, the output shaft of the drive motor 31 drives the driving bevel gear 32 to rotate. The driving bevel gear 32 meshes with the driven bevel gears 33, so that the driven bevel gears 33 rotate accordingly. The driven bevel gears 33 drive the export spiral blade 52 to start rotating through the connected drive shafts 51. During the rotation of the drive shaft 51, it also drives the transmission wheel 53 to rotate synchronously. The transmission wheel 53 transmits power to the driven wheel 54 by means of the connection of the transmission belt 55, and the driven wheel 54 drives the driven shaft 59 to rotate. The driven shaft 59 further drives the rotating plate 56 to rotate, so that the side teeth 57 installed on both sides of the rotating plate 56 also perform circular motion together.

[0046] When branches, leaves and other sundries flow into the inside of the drain trough 2 after being mixed with rainwater, since the upper and lower plate surfaces of the rotating plate 56 are both designed into an arc surface structure with a middle bulge, the rainwater and branches, leaves and other sundries will naturally flow to both sides of the rotating plate 56 under the dual action of gravity and the guidance of the arc surface. During this process, when the branches, leaves and other sundries with a larger volume reach the positions of the side teeth 57 and the fixed teeth 58, due to the continuous rotation of the rotating plate 56, the side teeth 57 will form a dynamic cooperation relationship with the fixed teeth 58 to efficiently crush the branches, leaves and other sundries, and gradually crush the originally larger-volume sundries into smaller-volume fragments.

[0047] Subsequently, the rainwater and the smaller-volume fragments after being crushed can enter the area below the drain trough 2 through the gaps between the fixed teeth 58 and the side teeth 57. While the rotating plate 56 continues to rotate, the driving shaft 51 always drives the export spiral blade 52 to rotate synchronously. When the rainwater and other sundries enter the area covered by the export spiral blade 52, under the continuous rotation of the export spiral blade 52, the rainwater and the crushed branches, leaves and other sundries are spirally conveyed to the discharge port 4 and finally smoothly discharged outwards through the discharge port 4. This design avoids the problem of blockage inside the drain trough 2 caused by the accumulation of sundries and ensures the smoothness of the drain trough 2 during the entire precipitation process.

[0048] The above description is only the preferred specific implementation manner of the present utility model. Based on the technical solution of this application and the relevant inspirations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments; the above specific embodiments are only explanations of this application and do not limit this application.
