[0003] In the existing technology, the arched fiberglass gas collecting hood is composed of multiple fiberglass arched hoods connected together. The connection between adjacent arched hoods is generally fixed by flanges. However, since the connection position is located at the top of the arched hood, it must be exposed to wind and sun, which will cause the bolts and nuts at the connection to oxidize, and then the connection force will be reduced, resulting in the risk of emission leakage.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] See also Figures 1 to 3In an embodiment of the present invention, a new type of fiberglass gas collecting hood includes a plurality of arched hoods 1 butted together in the axial direction. The outer wall of the arched hood 1 is integrally formed with an external reinforcing rib 2. Connecting flanges 3 are fixedly installed at both ends of the arched hood 1. A circular hole 4 is opened inside the connecting flange 3. Two adjacent arched hoods 1 are fixedly connected through the two connecting flanges 3 at the butt ends. Bolts pass through the circular holes 4 and are threadedly connected with nuts. The nuts in the locked state cooperate with the bolts to tighten the two connecting flanges 3. The inner wall of the arched hood 1 is fixedly connected with a reinforcement structure, which is used to further reinforce the bottom of the butt joint of the two arched hoods 1 to improve the stability of the arched hood 1.

[0019] In this embodiment, multiple arch covers 1 are laid along the axial direction, and bolts are used to penetrate two adjacent connecting flanges 3 in a fitted state. After the bolts penetrate the circular holes 4, nuts and bolts are tightened. After effective tightening, the hexagonal ends of the nuts and bolts effectively press the two adjacent connecting flanges 3, and the adjacent arch covers 1 can be connected and fixed. The above method is used in sequence to complete the fixing of multiple arch covers 1.

[0020] Afterwards, a reinforcement structure is used from the bottom of the arch cover 1 to further reinforce the bottom of the joint between the two arch covers 1 to further improve the firmness of the connection. At the same time, since the bolts and nuts are located above the arch cover 1, they are inevitably exposed to wind and sun, which will cause oxidation, thereby reducing the connection force. At this time, the reinforcement structure ensures the connection force between adjacent arch covers 1 from the inside.

[0021] Please refer to Figure 2 and Figure 3 The reinforcement structure includes two groups of fixing ears 7 fixedly connected to the inner wall of an arched cover 1, the number of fixing ears 7 in a group is multiple, and the multiple fixing ears 7 in a group are equidistantly distributed along the arched surface of the arched cover 1, and the two groups of fixing ears 7 on the inner wall of an arched cover 1 are symmetrically distributed. The reinforcement structure also includes a connecting column 8, and both ends of the outer wall of the connecting column 8 are provided with external threads 9. The connecting column 8 is used to connect the two adjacent groups of fixing ears 7 at the bottom of the two arched covers 1. A connecting hole 10 for inserting the connecting column 8 is provided inside the fixing ear 7. The outer wall of the external thread 9 is threadedly connected with a locking nut 11. The tightened locking nut 11 cooperates with the connecting column 8 to reinforce the bottom of the joint of the two arched covers 1.

[0022] In this embodiment: after the arch cover 1 is fixed from the outside above, a lifting platform is used to drive the operator to move to the upper part, and the operator uses the connecting column 8 to connect the adjacent fixing ears 7 at the bottom of the two arch covers 1. After the connection is completed, the locking nut 11 is used to lock the external threads 9 at both ends of the outer wall of the connecting column 8 to complete the reinforcement of the inner side of the arch cover 1, further improve the stability of the connection of the arch cover 1, and increase the service life of the device.

[0023] Please refer to Figure 1 and Figure 2 A sealing groove 5 is provided at one end of the arch cover 1 , and a sealing member 6 is connected to the other end of the arch cover 1 . The sealing member 6 contacts the sealing groove 5 at the joint of the two arch covers 1 .

[0024] In this embodiment: when two adjacent arch covers 1 are docked, the seal 6 on one arch cover 1 is inserted into the sealing groove 5 of the other arch cover 1. Since the seal 6 made of rubber is slightly larger than the sealing groove 5, the seal 6 is deformed under the action of the extrusion force, and the docking point of the two arch covers 1 is sealed, thereby ensuring airtightness.

[0025] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
