[0026] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Example 1

[0028] like Figure 1-2 , Figure 6 As shown, this embodiment proposes an arched fiberglass cover plate, including a head cover body 1, a tail cover body 2, and a plurality of connecting cover bodies 3, each connecting cover body 3 is located between the head cover body 1 and the tail cover body 2, and adjacent connecting cover bodies 3 are fixedly connected to each other, the connecting cover body 3 is fixedly connected to the head cover body 1, and the tail cover body 2 is fixedly connected to the connecting cover body 3, so as to avoid excessive gaps between adjacent cover bodies, which may cause gas to easily overflow along the gaps.

[0029] A connecting plate 31 and a connecting groove 32 are respectively provided on both sides of each connecting cover body 3. A matching plate 11 and a matching groove 21 are respectively provided on the front cover body 1 and the rear cover body 2. The matching groove 21 and each connecting groove 32 can be embedded in the connecting plate 31, and the matching plate 11 and each connecting plate 31 can be embedded in the connecting groove 32. Each connecting cover body 3 is arranged in sequence along a linear direction. Through the engagement of the plate and the groove, the connecting gaps between the front cover body 1 and the connecting cover body 3, the adjacent connecting cover bodies 3, and the connecting cover body 3 and the rear cover body 2 all present a non-linear complex structure such as a horizontal "U"-shaped structure. That is, this embodiment increases the difficulty of gas overflowing along the connecting gap by increasing the complexity of the connecting gap, thereby preventing air from overflowing from between adjacent cover bodies and polluting the surrounding air.

[0030] At the same time, a first sealing ring 6 and a support beam 4 are provided between the first cover body 1 and the connecting cover body 3, between adjacent connecting cover bodies 3, and between the connecting cover body 3 and the tail cover body 2. The first sealing ring 6 plays a role in sealing the connecting gaps between the cover bodies, thereby improving the sealing performance of this embodiment. The first cover body 1, the tail cover body 2, the connecting cover body 3, and the first sealing ring 6 are all located above the support beam 4, that is, the support beam 4 not only plays a role in supporting the first cover body 1, the tail cover body 2, and several connecting cover bodies 3, but also can block the connecting gaps between the three, thereby preventing gas from directly entering the connecting gaps, which in disguise increases the difficulty of gas overflowing along the connecting gaps, thereby ensuring the practicality of this embodiment.

[0031] Each first sealing ring 6 is respectively located at the notch of the matching groove 21 and each connecting groove 32, and the matching plate 11 or the connecting plate 31 abuts against the first sealing ring 6, that is, the surface of the matching plate 11 or the connecting plate 31 abuts against the inner ring of the first sealing ring 6, thereby ensuring the sealing effect of the first sealing ring 6 and preventing gas overflow.

[0032] The support beam 4 is an arch structure, and each support beam 4 is tangent to the first cover body 1 and the connecting cover body 3, between adjacent connecting cover bodies 3, and between the connecting cover body 3 and the tail cover body 2, that is, the arch structure of the support beam 4 is concentrically arranged with the first cover body 1, the tail cover body 2, and the arch structure of each connecting cover body 3, and is tangent thereto. With the help of the high bearing capacity of the arch structure, after the support beam 4 is fixed on a supporting surface such as a wall, the stability of the overall structure of this embodiment is guaranteed.

[0033] like Figure 3 to Figure 5 As shown, after the plate and the block are embedded and matched, the degrees of freedom in the vertical and horizontal directions between adjacent cover bodies are limited. On this basis, a number of fixing structures 5 are provided between the first cover body 1 and the connecting cover body 3, between adjacent connecting cover bodies 3, and between the connecting cover body 3 and the tail cover body 2. The fixed structures 5 limit the degrees of freedom in the horizontal direction between adjacent cover bodies, making the overall structure of this embodiment more stable.

[0034] Each fixing structure 5 includes a plurality of fixing holes 51, a plurality of fixing members 52, and a plurality of connecting holes 53. Each fixing hole 51 is concentrically arranged with each connecting hole 53. The fixing hole 51 is provided on the connecting plate 31 or the matching plate 11. The connecting hole 53 passes through one side of the connecting groove 32 or the matching groove 21. Each fixing member 52 is threadedly connected to each fixing hole 51 one by one, that is, the fixing between adjacent cover bodies is completed by threaded connection. The threaded connection structure is firm and reliable as a whole, and is easy to assemble and disassemble, which is convenient for the later maintenance of the cover body.

[0035] The fixing member 52 includes a limiting portion 521, the diameter of the limiting portion 521 is larger than the diameter of the connecting hole 53, and the limiting portion 521 abuts against the end face of the connecting hole 53, that is, the connecting hole 53 is shielded by means of the limiting portion 521 to prevent polluted gas from entering the interior of the fixing structure 5 along the connecting hole 53, breeding dirt, corroding the thread features of the fixing structure 5, and having a certain impact on later maintenance; and the position of the limiting portion 521 can also be used as a detection standard during the assembly process. When the limiting portion 521 abuts against the connecting hole 53, it means that the fixing member 52 has been connected in place, which is convenient for the staff to detect whether the thread is tightened.

[0036] The fixing member 52 in this embodiment is preferably a bolt with a nut, and the nut on the bolt can be directly used as the limiting portion 521. Since the bolt is one of the most common threaded parts on the market, when the fixing member 52 in this embodiment is lost, a replacement can be quickly found to ensure that this embodiment can be implemented normally.

[0037] Example 2

[0038] like Figure 2 to Figure 4 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes:

[0039] Each connecting hole 53 is arranged on a side of the connecting groove 32 or the matching groove 21 away from the supporting beam 4, that is, the connecting hole 53 is prevented from facing the sewage treatment system such as the sewage pool, and the gas is prevented from entering the fixed structure 5 along the connecting hole 53; at the same time, when the staff is performing maintenance work, they can stand on the roof to disassemble and assemble the fixing part 52, instead of needing to build a ladder in the house to disassemble and assemble the fixing part 52, which is convenient for the staff to perform maintenance on this embodiment in the later stage.

[0040] As time goes by, the portion of the first sealing ring 6 close to the sewage pool may be damaged due to the corrosiveness of the gas, causing part of the gas to enter the fixed structure along the gap between the plate and the groove, and then overflow from the gap between the connecting hole 53 and the limiting portion 521. Therefore, a second sealing ring 7 is provided at each connecting hole 53, and each limiting portion 521 abuts against the second sealing ring 7, that is, the second sealing ring 7 and the first sealing ring 6 cooperate with each other to prevent corrosive gas from overflowing from the gap between the limiting portion 521 and the connecting hole 53, thereby improving the sealing effect of this embodiment.

[0041] Example 3

[0042] like Figure 2 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes:

[0043] The longitudinal section of the support beam 4 is an inverted isosceles trapezoidal structure, so that the corrosive gas can be diverted by the structural shape of the support beam 4 during the rising process, and thus evenly guided to each cover body, preventing the corrosive gas from acting on the support beam 4 for a long time, corroding the support beam 4, and reducing the service life of the support beam 4.

[0044] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
