[0032] Most existing photovoltaic brackets use a water trough structure to be set at the gap position corresponding to the adjacent photovoltaic components below the photovoltaic components, and use the water trough to receive and guide rainwater or snow and other debris falling from the gap, thereby preventing water accumulation or accumulation of debris at the bottom of the photovoltaic bracket, and ensuring the stable operation of the photovoltaic power station. However, most existing water trough structures use a multi-section connection structure, and the structural strength of the segmented connection of the water trough structure is low, which reduces the bearing capacity of the water trough structure, and cannot make good use of the water trough structure to support the photovoltaic components, reducing the practicality and reliability of the water trough structure. In view of the above problems, the utility model proposes a water trough structure 100.

[0033] Reference Figures 1 to 7In an embodiment of the utility model, the water tank structure 100 includes at least two water tank units 10 and a connecting piece 30. The water tank unit 10 is formed with a drainage groove 11. The water tank unit 10 is defined to have a first end 13 and a second end 15. The first end 13 of one water tank unit 10 is clamped in the drainage groove 11 of another adjacent water tank unit 10 and overlaps with the second end 15 of the water tank unit 10; the connecting piece 30 connects and fixes the two adjacent water tank units 10.

[0034] It is understandable that the photovoltaic power station can be installed on the assembly platform by using the photovoltaic bracket anchor, so that the support frame of the photovoltaic bracket can stably support the water tank structure 100, and the water tank structure 100 can be stably installed in the gap between adjacent photovoltaic components, to ensure the stable bearing of the photovoltaic components by the water tank structure 100 and the collection of rainwater, snow water and other debris on the photovoltaic components, to avoid the accumulation of water or debris at the bottom of the photovoltaic bracket, and to better ensure the stable operation of the photovoltaic power station. Among them, the support frame can be installed on the assembly platform by using structures such as columns or tripods, and then a plurality of columns or tripods can be connected by using rods such as beams to form a relatively stable frame structure as a whole. At this time, the water tank structure 100 is installed and fixed on the support frame by using bolts or clamps and other mounting components, and the support frame can be well used to support the water tank structure 100, to ensure that when the photovoltaic components are installed on the water tank structure 100, the support frame can be used to better share the force on the water tank structure 100, and further ensure the overall structural stability of the photovoltaic bracket.

[0035] In the present application, the water tank structure 100 can use the connector 30 to connect multiple water tank units 10 end to end to form a whole, so as to facilitate the production, transportation and on-site construction and assembly of the water tank structure 100, and ensure the overall structural stability of the water tank structure 100. By setting the size of the second end 15 of the water tank unit 10 slightly larger than the size of the first end 13, or making the water tank unit 10 made of a material with good toughness and elasticity, the first end 13 of one water tank unit 10 can be inserted into the drainage groove 11 at the second end 15 of another water tank unit 10 during assembly, and the inner wall of the drainage groove 11 at the second end 15 of the water tank unit 10 is tightly fitted with the outer periphery of the first end 13 of the water tank unit 10, so that the two water tank units 10 can be overlapped, which is conducive to better ensuring the force transmission between the two water tank units 10, reducing the stress concentration caused by excessive force on the local water tank unit 10 in the water tank structure 100, and ensuring the overall structural stability of the water tank structure 100. By using the connecting member 30 to connect and fix the two overlapping water tank units 10, the connecting member 30 can be configured with a structure having a certain contact area such as a plate, so that the connecting member 30 can be arranged in the drainage groove 11 and simultaneously abut against the inner wall of the drainage grooves 11 of the two water tank units 10; or the connecting member 30 can be connected to the outer periphery of the two water tank units 10 and simultaneously abut against the outer wall of the two water tank units 10; or the connecting member 30 can be clamped on the inner wall of the drainage groove 11 of the first end 13 of one water tank unit 10 or clamped on the second end 13 of the other water tank unit 10. 5, so that the first end 13, the second end 15 and the connecting member 30 of the two adjacent connected water tank units 10 can be better overlapped and matched, and then under the action of the connecting member 30, the two water tank units 10 can be better connected to form a whole, so that the force transmission between the two water tank units 10 can be better realized by means of the contact connection function of the connecting member 30, effectively avoiding the fracture and damage at the contact position between the two adjacent water tank units 10, further improving the structural strength of the connection position of the water tank unit 10, and improving the overall structural stability and reliability of the water tank structure 100. Among them, the connecting member 30 can be fastened and installed with the two overlapping connected water tank units 10 by fasteners such as bolts or clips, so as to ensure that the connecting member 30 can be more firmly connected and fixed on the water tank unit 10, and the connecting member 30 can fix the two water tank units 10 more stably and reliably, avoiding the detachment of the connecting member 30 on the water tank structure 100 and causing the two adjacent connected water tank units 10 to separate with a certain probability, ensuring the stable support and bearing function of the photovoltaic bracket, and further improving the practicality and reliability of the water tank structure 100.

[0036] The technical solution of the present invention achieves extended installation of the water tank structure 100 by overlapping and clamping the first end portions 13 and the second end portions 15 of two adjacent water tank units 10, and then connecting and fixing the two water tank units 10 using a connecting piece 30. The water tank units 10 can overlap and fit with each other, and the two water tank units 10 can be fixed with the connecting piece 30, so that the water tank structure 100 can utilize the overlap of the water tank units 10 to improve the structural strength and rigidity of the connection of the water tank units 10, ensure the force transmission between the water tank units 10, effectively avoid the connection of the water tank structure 100 from breaking, ensure the overall stability of the water tank structure 100, and help the water tank structure 100 to more stably carry the photovoltaic components, further improving the practicality and reliability of the water tank structure 100.

[0037] Reference Figure 2 and Figure 7 In one embodiment of the utility model, the bottom wall of the drainage groove 11 is provided with a reinforcing rib 111 extending along the extension direction of the water trough unit 10, and the reinforcing rib 111 of the first end 13 of one water trough unit 10 overlaps with the reinforcing rib 111 of the second end 15 of another adjacent water trough unit 10.

[0038] In this embodiment, by providing reinforcing ribs 111 extending along the extension direction of the water tank unit 10 on the protrusion of the bottom wall of the drain groove 11, the reinforcing ribs 111 can be used to better improve the structural strength and rigidity of the water tank unit 10, which is beneficial to utilizing the reinforcing ribs 111 to better alleviate the stress concentration on the bottom wall of the drain groove 11 of the water tank unit 10, thereby further improving the structural stability and reliability of the water tank unit 10. Among them, the reinforcing rib 111 can be integrally stamped on the sink unit 10 by a stamping device. While the reinforcing rib 111 is protruded on the bottom wall of the drain groove 11, a groove structure corresponding to the reinforcing rib 111 can be formed at the bottom of the sink unit 10. The groove structure is also extended along the extension direction of the sink unit 10. Therefore, when the first end 13 and the second end 15 of two adjacent sink units 10 overlap and snap-fit, the groove structure on the bottom surface of the first end 13 of one sink unit 10 can be engaged with the reinforcing rib 111 in the drain groove 11 of the second end 15 of the other sink unit 10, which is beneficial to further improve the structural strength of the connection of the sink unit 10 by utilizing the mutual cooperation of the reinforcing ribs 111 when the sink units 10 are connected, and further improve the connection stability and reliability of the sink structure 100.

[0039] Reference Figure 6 and Figure 7In one embodiment of the utility model, a plurality of reinforcing bosses 113 are protruding from the bottom wall of the drain trough 11, and the plurality of reinforcing bosses 113 are arranged in sequence along the extension direction of the water trough unit 10, and the reinforcing boss 113 of the first end 13 of a water trough unit 10 overlaps with the reinforcing boss 113 of the second end 15 of another adjacent water trough unit 10.

[0040] In this embodiment, a plurality of reinforcing bosses 113 are arranged in sequence on the bottom wall of the drain trough 11. The reinforcing bosses 113 can be arranged in regular or irregular shapes such as square and circle. The structural setting of the reinforcing bosses 113 can be used to better improve the structural strength and rigidity of the water trough unit 10 and alleviate the stress concentration of the water trough unit 10. At the same time, the structural strength of the water trough unit 10 can be enhanced by using the raised reinforcing bosses 113. The thickness of the plate of the water trough unit 10 on the bottom wall of the drain trough 11 can be better reduced, thereby reducing the material cost of the water trough unit 10 and further improving the practicality and reliability of the water trough unit 10.

[0041] Among them, the reinforcing boss 113 can be integrally stamped and formed at the bottom of the sink unit 10 by a stamping device, so that the bottom surface of the sink unit 10 can form a groove structure corresponding to the reinforcing boss 113, and then when the first end 13 and the second end 15 of two adjacent sink units 10 overlap and snap-fit, the groove structure on the bottom surface of the first end 13 of one sink unit 10 can be engaged with the reinforcing boss 113 in the drain groove 11 of the second end 15 of the other sink unit 10, which is beneficial to further improve the structural strength of the connection of the sink unit 10 by utilizing the mutual cooperation of the reinforcing boss 113 when the sink units 10 are connected. At the same time, the two adjacent sink units 10 can be better prevented from moving relative to each other under the cooperative snap-fitting action of the reinforcing boss 113, thereby achieving more stable and reliable force transmission between the two adjacent sink units 10, and further improving the connection stability and reliability of the sink structure 100.

[0042] Reference Figures 2 to 4 In one embodiment of the utility model, the connecting member 30 includes a lower clamping plate 31 and a fastening member 33. The lower clamping plate 31 is provided with a fixing groove 311. The lower clamping plate 31 is used to clamp the water tank unit 10 so that the inner wall of the fixing groove 311 abuts against the outer wall of the water tank unit 10; the fastening member 33 connects the lower clamping plate 31 and the water tank unit 10.

[0043] In this embodiment, the lower clamping plate 31 can be a "U"-shaped trough structure that matches the outer wall shape of the water tank unit 10. During assembly, the lower clamping plate 31 can be overlapped and clamped to the outer wall of the second end portion 15 of the water tank unit 10 located below, and the overlapping lower clamping plate 31 and the two water tank units 10 are connected and fixed by the fastening member 33 to ensure that the connection and fixation of the two water tank units 10 by the connecting member 30; or, the lower clamping plate 31 can be installed at the connection between two adjacent water tank units 10, so that part of the structure of the lower clamping plate 31 is corresponding to clamping one water tank unit 10, and the other part of the structure of the lower clamping plate 31 is corresponding to clamping the other water tank unit 10. At this time, the lower clamping plate 31 can be made of a material with good toughness or elasticity, and the part of the structure of the lower clamping plate 31 can undergo a certain elastic deformation under the fastening action of the fastening member 33, and at the same time, it can be tightly fitted against the two water tank units 10, or the fixing groove of the lower clamping plate 31 can be composed of two stepped grooves to ensure that the lower clamping plate 31 can more tightly abut the overlapping part of the structure of the two water tank units 10, so that the connecting member 30 can use the lower clamping plate 31 set in accordance with the shape of the water tank unit 10 to more firmly clamp and fix the two adjacent water tank units 10, so as to achieve a tight fitting connection between the connecting member 30 and the outer walls of the two water tank units 10. Therefore, under the clamping and fixing action of the lower clamping plate 31, it is beneficial to better utilize the lower clamping plate 31 to realize the force transmission of the two adjacent water tank units 10, and further improve the structural strength and rigidity of the connection of the water tank units 10. In addition, the connecting piece 30 can use fastening components 33 such as bolts and clips to connect and fix the lower clamp plate 31 and the two water tank units 10, thereby better improving the connection stability and reliability of the connecting piece 30 and the water tank unit 10, preventing the connecting piece 30 from detaching from the water tank unit 10 and causing the two water tank units 10 to separate from each other with a certain probability, thereby ensuring the overall structural stability of the photovoltaic bracket; at the same time, the fastening connection of the fastening component 33 can also better keep the lower clamp plate 31 in close contact with the two water tank units 10, further improving the overall structural stability and reliability of the water tank structure 100.

[0044] When the bottom wall of the drain groove 11 of the sink unit 10 is stamped with reinforcing ribs 111 or reinforcing bosses 113, corresponding reinforcing ribs 111 or reinforcing bosses 113 can be formed on the surface where the lower clamping plate 31 and the bottom surface of the sink unit 10 are in contact, so that when the lower clamping plate 31 clamps and fixes the two sink units 10, the corresponding raised structure on the lower clamping plate 31 and the groove structure of the corresponding reinforcing ribs 111 or reinforcing bosses 113 on the bottom surface of the sink unit 10 can be used to engage with each other, which is conducive to better improving the connection stability and reliability between the lower clamping plate 31 and the sink unit 10, achieving better force transmission between the lower clamping plate 31 and the sink unit 10, and further improving the overall structural stability and reliability of the sink structure 100.

[0045] Reference Figure 3 and Figure 4 In one embodiment of the present invention, the connector 30 further includes an upper clamping plate 35, which is clamped in the drain groove 11 of the water tank unit 10 and abuts against the inner wall of the drain groove 11. The upper clamping plate 35 is provided with an escape groove 351, and the escape groove 351 communicates the drain grooves 11 of the two water tank units 10. The fastening member 33 connects the lower clamping plate 31, the water tank unit 10 and the upper clamping plate 35, so that the upper clamping plate 35 and the lower clamping plate 31 clamp and fix the overlapping first end 13 and second end 15 of the two water tank units 10.

[0046] In this embodiment, the connecting member 30 can also be provided with an upper clamping plate 35, which can be a groove structure set corresponding to the longitudinal cross-sectional shape of the drain groove 11 of the water tank unit 10, so that after the two adjacent water tank units 10 are overlapped and installed by using the first end 13 and the second end 15, the upper clamping plate 35 can be used to snap into the drain grooves 11 of the two water tank units 10, and a part of the structure of the upper clamping plate 35 is in contact with the inner wall of the groove of the drain groove 11 of one water tank unit 10, so that the other part of the structure of the upper clamping plate 35 is in contact with the inner wall of the groove of the drain groove 11 of the other water tank unit 10. The inner wall of the drain groove 11 is fitted and abutted. At this time, the upper clamping plate 35 can be made of a material with good toughness or elasticity. Under the fastening action of the fastening member 33, the partial structure of the upper clamping plate 35 can undergo a certain elastic deformation and tightly fit and abut the inner wall of the drain groove 11 of the two water tank units 10. Alternatively, the outer wall of the upper clamping plate 35 can be set with a step structure corresponding to the step structure formed in the drain groove 11 after the two water tank units 10 are spliced ​​together, so as to ensure that the outer wall of the upper clamping plate 35 can more tightly abut the inner wall of the drain groove 11 of the two water tank units 10. Alternatively, the upper clamping plate 35 can be clamped in the drain groove 11 of the upper water tank unit 10, and the upper clamping plate 35 and the two water tank units 10 are connected and fixed by the fastening member 33, so that the upper clamping plate 35 can overlap and fit the two water tank units 10. At this time, the lower clamping plate 31 can be arranged corresponding to the upper clamping plate 35 when clamping and fixing the two water tank units 10, and then the upper clamping plate 35, the water tank unit 10 and the lower clamping plate 31 are connected by the fastening member 33, and the upper clamping plate 35 and the lower clamping plate 31 can be clamped and fixed with the two overlapping water tank units 10 under the fastening connection of the fastening member 33, further improving the connection stability and reliability of the water tank unit 10. Among them, the upper clamping plate 35 can be recessed to form an avoidance groove 351 that communicates with the drainage grooves 11 of the two water tank units 10 to ensure smooth water flow in the water tank structure 100, further improving the practicality and reliability of the water tank structure 100.

[0047] In addition, when the bottom wall of the drain groove 11 of the sink unit 10 is stamped with reinforcing ribs 111 or reinforcing bosses 113, a corresponding groove structure can be formed on the bottom surface where the upper clamp 35 and the bottom wall of the drain groove 11 of the sink unit 10 are in contact, so that when the upper clamp 35 is clamped in the drain grooves 11 of the two sink units 10, the groove structure on the bottom surface of the upper clamp 35 can be used to cooperate with the reinforcing ribs 111 or reinforcing bosses 113 on the bottom wall of the drain groove 11 of the sink unit 10 to overlap and clamp, which is conducive to better improving the connection stability and reliability between the upper clamp 35 and the sink unit 10, achieving better force transmission between the upper clamp 35 and the sink unit 10, and at the same time, allowing the connecting piece 30 to clamp and fix the two sink units 10 more firmly, further improving the overall structural stability and reliability of the sink structure 100.

[0049] In this embodiment, the photovoltaic support can be connected to a water collecting trough or drainage pipe corresponding to the multiple parallel water trough structures 100 on the support frame, so that the rainwater, snow water and other debris collected by the multiple water trough structures 100 can be better concentrated and discharged, further improving the sewage discharge efficiency of the photovoltaic power station, and improving the practicality and reliability of the water trough structure 100. Among them, by setting a confluence hole 115 on the bottom wall of the drainage trough 11, the rainwater, snow water and other debris in the drainage trough 11 can be better concentrated and discharged from the confluence hole 115 to the water collecting trough or drainage pipe on the support frame, so as to achieve stable discharge of the water trough structure 100, reduce the accumulation of debris in the drainage trough 11 and overflow from both sides of the water trough unit 10 with a certain probability, better prevent the formation of water accumulation or accumulation of debris at the bottom of the photovoltaic support, and further improve the practicality and reliability of the water trough structure 100.

[0051] In this embodiment, a flow-gathering edge 117 is formed on the periphery of the confluence hole 115, and the flow-gathering edge 117 is raised and arranged on the bottom surface of the trough unit 10. The flow-gathering edge 117 can be used to guide the water flowing through the confluence hole 115, thereby ensuring that the water in the drainage trough 11 can flow through the confluence hole 115 more stably and fall into the sump or drain pipe, effectively preventing the water from diverging when passing through the confluence hole 115 and causing a certain probability of water splashing, thereby achieving stable collection of rainwater, snow water and other debris falling on the photovoltaic module by the photovoltaic bracket, effectively avoiding the formation of water accumulation or debris accumulation at the bottom of the photovoltaic bracket, and further improving the structural stability and reliability of the trough structure 100. Among them, the inner diameter of the flow-gathering edge 117 can be gradually reduced from top to bottom, so that the flow-gathering edge 117 can form a circular ring structure that is wide at the top and narrow at the bottom, which is conducive to better improving the flow-gathering and diversion effect of the flow-gathering edge 117, and further avoiding water splashing during centralized drainage of the drainage trough 11, further improving the practicality and reliability of the trough structure 100.
