[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than 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 efforts belong to the scope of protection of the present utility model.

[0027] According to the attached Figures 1-5As shown in the figure, an embodiment of the utility model provides a photovoltaic module water assembly base, which includes a base assembly 1. Above the base assembly 1, there are several uniformly distributed photovoltaic panels 4. The base assembly 1 includes square floating platforms 2 distributed in an array. A cross bar 21 is arranged between the square floating platforms 2 on the left and right sides for connection. A conical floating platform 3 is arranged between the square floating platforms 2 on the front and back sides. Vertical rods 31 connected to the square floating platforms 2 are arranged on the front and back sides of the conical floating platform 3. A counterweight 5 is arranged below the square floating platform 2. An adjusting mechanism is arranged between the base assemblies 1 on the front and back sides. The adjusting mechanism includes a fixed frame 6, a movable frame 62 and an adjusting rod 63, which are used to adjust the distance between the base assemblies 1 on the front and back sides.

[0028] The base assembly 1 is composed of several square floating platforms 2 and conical floating platforms 3. The square floating platforms 2 and conical floating platforms 3 adopt a modular design, which is convenient for quickly installing, maintaining and replacing photovoltaic modules on the water, and can reduce the occupied area of the water area. At the same time, the modular design can also achieve standardized production and reduce costs. In addition, due to its wider top, the conical floating platform 3 helps to improve the stability of the floating platform and reduce the impact force of water flow on the conical floating platform 3 while providing a larger buoyancy distribution area. When the square floating platforms 2 and conical floating platforms 3 are assembled, the base assembly 1 has high stability and anti-wind and wave capabilities.

[0029] The adjusting mechanism can connect and fix the two groups of base assemblies 1 on the front and back, further improving the stability of the photovoltaic module base. At the same time, the adjusting mechanism can adjust and control the distance between the two groups of base assemblies 1 on the front and back to avoid the distance between the two groups of base assemblies 1 being too small and affecting the maintenance work.

[0030] An inner skeleton 22 is arranged inside the square floating platform 2. The structure of the square floating platform 2 can be strengthened through the inner skeleton 22 to improve the structural performance of the square floating platform 2. An end of the inner skeleton 22 is provided with a first installation sleeve 23 that penetrates the four side walls and the top of the square floating platform 2. The left and right ends of the cross bar 21 are respectively inserted and matched with the first installation sleeves 23 on adjacent square floating platforms 2. A through hole is opened at the end of the first installation sleeve 23, and the cross bar 21 can be further fixed by bolts through the through hole.

[0031] A cavity 24 is arranged inside the square floating platform 2. The design of the cavity 24 can further enhance the buoyancy effect of the square floating platform 2. The upper surface of the square floating platform 2 is a drainage slope 25 distributed symmetrically obliquely, so that the top of the square floating platform 2 has a good drainage effect and prevents water from accumulating on the top of the square floating platform 2.

[0032] The upper surface of the conical floating platform 3 adopts a conical surface structure, which has good drainage effect. Second mounting sleeves 32 symmetrically distributed front and back are arranged on the conical floating platform 3 and close to the top end. Through holes are opened at the ends of the second mounting sleeves 32. One end of the vertical rod 31 is inserted and matched with the first mounting sleeve 23, and the other end of the vertical rod 31 is inserted and matched with the second mounting sleeve 32, and both ends are fixed by bolts.

[0033] The square floating platform 2 and the conical floating platform 3 are both made of cross-linked polyethylene material, which makes the square floating platform 2 and the conical floating platform 3 have good buoyancy, high corrosion resistance, anti-aging performance and mechanical properties, which helps to continuously face the corrosion and scouring of the water body. Corrosion-resistant coatings are provided on the outer surfaces of the square floating platform 2 and the conical floating platform 3. The corrosion-resistant coatings are made of fluorocarbon coatings, and specifically, polytetrafluoroethylene or polyvinylidene fluoride can be used, which can further enhance the protection of the square floating platform 2 and the conical floating platform 3, making them have excellent corrosion resistance, weather resistance and ultraviolet resistance.

[0034] Mounting brackets 41 are welded and fixed at the bottom of the photovoltaic panel 4 and close to the four corners. The bottom end of the mounting bracket 41 is inserted and matched with the first mounting sleeve 23 on the top of the square floating platform 2 and is fixed by bolts.

[0035] A fixed sleeve 51 integrally formed is arranged at the bottom of the square floating platform 2 and close to the center. A connecting rod 52 is arranged at the top of the counterweight 5. The top end of the connecting rod 52 is threadedly connected with the fixed sleeve 51. After the base assembly 1 is assembled, different numbers of counterweights 5 can be installed at the bottom of the square floating platform 2, so as to control the overall counterweight of the base assembly 1, thereby controlling the water entry depth of the square floating platform 2 and the conical floating platform 3, which is beneficial to enhancing the anti-wave performance of the base.

[0036] Two groups of fixed frames 6 are symmetrically distributed front and back, and fixing rods 61 inserted and matched with the first mounting sleeve 23 are welded and fixed on the fixed frames 6. Two groups of movable frames 62 are symmetrically distributed left and right. Four groups of adjusting rods 63 are distributed in a rhombus shape between the fixed frames 6 and the movable frames 62, and both ends of the adjusting rods 63 are rotatably connected with the fixed frames 6 and the movable frames 62 respectively.

[0037] A bidirectional lead screw 64 passing through the movable frame 62 is arranged between the front and rear fixed frames 6. Both ends of the bidirectional lead screw 64 are threadedly connected with the movable frame 62, and handles 65 are welded and fixed on both sides of the bidirectional lead screw 64.

[0038] When the bidirectional lead screw 64 is rotated through the handle 65, since the movable frames 62 are symmetrically arranged on the bidirectional lead screw 64, the bidirectional lead screw 64 can drive the movable frames 62 to perform linear movement and synchronously adjust the distance between the two groups of movable frames 62. At the same time, one end of the adjusting rod 63 rotates on the fixed frame 6, and the other end of the adjusting rod 63 rotates on the movable frame 62, which can drive the fixed frames 6 on the front and back sides to move synchronously, so as to adjust and control the distance between the two groups of base components 1 at the front and back through the fixed frame 6, facilitating the maintenance and repair of the photovoltaic modules.

[0039] When the photovoltaic module water assembly base of the present utility model is in use, first, both ends of the vertical rod 31 are fixedly connected to the first mounting sleeve 23 and the second mounting sleeve 32 respectively, and the square floating platform 2 and the conical floating platform 3 are preliminarily assembled. When the square floating platform 2 and the conical floating platform 3 are placed on the water surface, both ends of the cross bar 21 are fixedly connected to the first mounting sleeve 23 to assemble the square floating platforms 2 on the left and right sides, thereby assembling the base component 1 distributed horizontally. Then, the bottom end of the mounting frame 41 is fixedly connected to the first mounting sleeve 23 to install and fix the photovoltaic panel 4.

[0040] Furthermore, the fixing rod 61 on the fixed frame 6 is fixedly connected to the first mounting sleeve 23 on the two groups of square floating platforms 2 at the front and back. The fixed frame 6, the movable frame 62 and the adjusting rod 63 are cooperated to connect and fix the two groups of base components 1. When maintenance is required, only the bidirectional lead screw 64 needs to be rotated to adjust the distance between the two groups of base components 1.

[0041] The above shows and describes the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only the preferred examples of the present utility model and do not limit the present utility model.
