Detailed Description
The following describes the embodiments of the present invention in detail, and the embodiments and specific operation procedures are given on the premise of the technical solution of the present invention, but the scope of protection of the present invention is not limited to the following embodiments.
A waterproof photovoltaic connector protection device for an offshore photovoltaic system, as shown in fig. 1-8, comprises a main body sealing member 1 and a waterproof member 2,
The main body sealing member 1 comprises an outer housing 11 and an inner housing 12 which are mutually clamped and matched, an inner cavity for placing the photovoltaic connector is formed after the outer housing 11 and the inner housing 12 are clamped and matched,
The waterproof member 2 is provided between mating surfaces of the outer case 11 and the inner case 12 for preventing moisture from entering the inner chamber,
The inner walls of the two sides of the clamping fit of the outer shell 11 and the inner shell 12 are provided with an upper clamping groove 112 and a lower clamping groove 113 which are not communicated with each other, a connecting surface is arranged between the upper clamping groove 112 and the lower clamping groove 113, the two side walls of the inner shell 12 are provided with clamping pieces 122 which are in clamping fit with the lower clamping groove 113, the side walls of the clamping pieces 122 are clamped in the lower clamping groove 113, the two side walls of the inner shell 12 above the clamping pieces 122 are clamped on the connecting surface between the upper clamping groove 112 and the lower clamping groove 113,
The upper clamping groove 112, the lower clamping groove 113 and the clamping piece 122 adopt a triangular structure,
The included angle alpha generated by the upper clamping groove 112 and the Y axis ranges from 20 degrees to 23 degrees, and the height H1 of the upper clamping groove 112 ranges from 0.3a to 0.32a; the included angle beta between the lower clamping groove 113 and the Y axis is 33-35 degrees, and the height H2 of the lower clamping groove 113 is 0.32a-0.34a; the included angle theta between the clamping member 122 and the Y axis is in the range of 30-32 degrees, and the height H3 of the clamping member 122 is in the range of 0.29a-0.31a; the height H4 of the connection surface between the upper clamping groove 112 and the lower clamping groove 113 is 0.08a-0.10a, the height H5 of the side wall of the inner housing 12 above the clamping piece 122 is 0.12a-0.13a, wherein H2 > H1 > H3, and a is the outer diameter of the connection end of the photovoltaic connector. The included angle alpha is smaller than the included angle theta, so that a certain acting force is generated on the outer shell 11 when the clamping piece 122 is clamped downwards, and the deformation capacity clamping piece 122 of the outer shell 11 can enter the lower clamping groove 113 after continuously passing through the connecting surface downwards; the included angle beta is larger than the included angle theta, so that the deformation of the outer shell 11 can be recovered conveniently, and meanwhile, the clamping piece 122 can translate and be clamped with the lower clamping groove 113 within a certain range. Meanwhile, the included angle alpha is about 20 degrees, so that better stability is provided, and the clamping piece 122 is not easy to shake or slip in the inserting process; when the included angle θ is too large, that is, exceeds 40 °, a large obstruction is generated when the clamping member 122 is inserted, friction between the clamping member 122 and the clamping groove is increased, and a clamping phenomenon occurs, which is not beneficial to integral sealing.
The clamping pieces 122 are provided with an odd number, one side edge is provided with 4 clamping pieces 122, the other side edge is provided with 5 clamping pieces 122, the clamping pieces 122 on the inner walls of the two sides are crossed to form a W-shaped structure, and the clamping pieces 122 on the two side edges are mutually misaligned in the Y direction. When the clamping operation is carried out, deformation parts on two side edges of the outer shell 11 are not overlapped in the Y direction, one side is stressed, so that the operation is convenient, and the deformation generated on the other side is easy to recover.
The flashing comprises a port flashing ring 21 and a flashing collar 22,

The waterproof collar 22 adopts a rectangular structure with chamfers, the two side walls of the inner shell 12 are provided with collar inner grooves 123 which are matched with the two side edges of the waterproof collar 22, the diameter of the waterproof collar 22 is 0.36a-0.4a, and the depth H6 of the collar inner grooves 123 is 0.18a-0.2a. The height at which the waterproof collar 22 deforms within the collar groove 123 (i.e., the diameter-H6 of the waterproof collar 22) is much greater than the height at which the retainer 122 translates within the lower snap groove 113 (i.e., H2-H3), and even if the retainer 122 translates in the vertical direction, the outer housing 11 and the inner housing 12 remain sealed. Meanwhile, the depth H6 of the groove 123 in the clamping ring is set to be 0.18a-0.2a, namely the cross section area of the through hole in the middle of the protection device is about 10 times that of the groove 123 in the side clamping ring, so that the overall cross section area of the protection device is increased, the strength and durability of the structure are improved, the deformation of the overall structure when being stressed is reduced, and the stability and the accuracy of the structure are maintained. When the depth H6 is greater than 0.25a, the diameter of the waterproof collar 22 is likewise greater than 0.5a, and the stability of the overall structure is greatly reduced.
The upper port waterproof ring in the inner housing 12 is integral with the waterproof collar 22.
The upper port waterproof ring and the lower port waterproof ring are mutually spliced up and down to form a through hole through which two connecting ends of the capacitive photovoltaic connector tightly pass.
The two inner walls of the outer shell 11 and the inner shell 12 are provided with outer positioning columns 111, and the two side walls of the inner shell 12 are provided with positioning column grooves 121 which are in up-down tight plug-in fit with the outer positioning columns 111.
The outer surface of the body seal 1 is provided with a chamfer and a bulge for cushioning. The main body sealing piece 1 is made of PPO.
During assembly, the upper port waterproof ring and the waterproof collar 22 are firstly placed in the inner shell 12, the lower port waterproof ring is placed in the outer shell 11, then the photovoltaic connector is placed in the inner cavity of the inner shell 12, and then the outer shell 11 is in clamping fit with the inner shell 12, wherein the clamping fit is specifically as follows: firstly, a positioning column groove 121 of an inner shell 12 is inserted into an outer positioning column 111 of an outer shell 11, meanwhile, after a wedge-shaped side wall of a clamping piece 122 passes through an upper clamping groove 112, a side edge of the outer shell 11 with the clamping groove is deformed to a certain extent when the clamping piece 122 passes through a connecting surface between the upper clamping groove 112 and a lower clamping groove 113, then the clamping piece 122 enters into the lower clamping groove 113 through the connecting surface, the outer shell 11 recovers deformation, meanwhile, the wedge-shaped side wall of the clamping piece 122 is clamped in the lower clamping groove 113, and two side walls of the inner shell 12 above the clamping piece 122 are clamped in the connecting surface between the upper clamping groove 112 and the lower clamping groove 113; after the clamping fit, the upper port waterproof ring and the lower port waterproof ring are mutually spliced up and down to form through holes through which two connecting ends of the photovoltaic connector closely pass, and meanwhile, as the clamping grooves of the waterproof clamping ring 22 are not formed in the outer shell 11, the outer shell 11 and the waterproof clamping ring 22 are tightly matched under the clamping fit, even if the clamping piece 122 translates in the vertical direction, the outer shell 11 and the inner shell 12 are still sealed.
