[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figure 1 As shown, a marine flexible ventilation duct includes a ventilation duct body 1 and a flange 4. A fixing component 5 for mounting one end of the ventilation duct body 1 is provided on one side of the flange 4.

[0023] In a specific embodiment, one end of the ventilation pipe body 1 is tightly connected to the flange 4 to facilitate installation.

[0024] As a technical optimization solution of this utility model, such as Figures 1 to 4 As shown, the fixing component 5 includes a rigid plastic collar 51. The rigid plastic collar 51 is fixedly connected to one end of the ventilation pipe body 1 near the flange 4. The rigid plastic collar 51 has slots 52 evenly spaced inside on one side of its ring. Multiple locking blocks 54 are inserted into the slots 52 respectively. A sliding block 55 is fixedly connected to one end of each locking block 54. The sliding blocks 55 are slidably sleeved inside the flange 4 at equal intervals. The flange 4 has grooves 56 evenly spaced inside on one side of its ring. The sliding blocks 55 are slidably sleeved inside the grooves 56 respectively. Fixing holes 58 are provided on the inner walls of the grooves 56. Threaded bolts 57 are threadedly connected to the center of each sliding block 55. The threaded bolts 57 are threadedly connected to the sliding blocks 55 and the fixing holes 58 respectively.

[0025] In a specific embodiment, the rigid plastic collar 51 is fixedly connected to one end of the ventilation pipe body 1 by heat fusion. By fixing the rigid plastic collar 51 to the side of the ventilation pipe body 1 near the flange 4, a firm installation is ensured. At the same time, a sliding groove 56 and a fixing hole 58 are opened on the flange 4, and a sliding block 55 is fitted inside the flange 4 so that the locking block 54 corresponds to the locking groove 52 on the rigid plastic collar 51. The ventilation pipe body 1 is close to the flange 4, so that the locking groove 52 on the rigid plastic collar 51 is aligned with the locking block 54, and then the locking block 54 is inserted into the locking groove 52. At this time, the sliding block 55 will slide inside the flange 4 as the locking block 54 is inserted and enters the corresponding sliding groove 56. Thus, it is threaded to the center of the sliding block 55 by a threaded bolt 57 and screwed into the corresponding fixing hole 58. The sliding block 55 is fixed in the sliding groove 56 by the threaded bolt 57, thereby realizing the fixed connection between the ventilation pipe body 1 and the flange 4.

[0026] By using the fixing component 5, multiple sliding blocks 55 move within the groove 56 of the flange 4 of the ventilation equipment, thereby driving multiple locking blocks 54 to be inserted into the groove 52 of the rigid plastic collar 51. The sliding blocks 55 are fixed in the groove 56 by the threaded bolts 57, thus achieving a fixed connection between the ventilation pipe body 1 and the flange 4. This reduces the need for operators to use wire ropes or other straps to fix one end of the flexible ventilation pipe, avoiding the need for repeated manual winding and knotting, which consumes a lot of time and effort. It also prevents the wire ropes or straps from loosening or slipping due to continuous vibration, airflow impact, etc., which could cause the ventilation pipe to fall off.

[0027] As a technical optimization solution of this utility model, such as Figures 1 to 2 As shown, a reinforcing layer 3 is bonded to the inner wall surface of the ventilation duct body 1, and the reinforcing layer 3 is located on the inner wall surface of the ventilation duct body 1. A sealing layer 2 is bonded to the inner wall surface of the reinforcing layer 3, and the sealing layer 2 is located on the inner side of the ventilation duct body 1 and the inner wall surface of the reinforcing layer 3.

[0028] In a specific embodiment, the selected reinforcing layer 3 material is cut according to the dimensions of the inner wall of the ventilation duct, completely covering the part of the inner wall of the ventilation duct that needs reinforcement. Then, adhesive is evenly applied to one side of the reinforcing layer 3 material and the inner wall surface of the ventilation duct body 1. The adhesive is usually a product that is resistant to high temperature and moisture and has good adhesion, such as epoxy resin adhesive. After the application is completed, the reinforcing layer 3 material is carefully pasted onto the inner wall of the ventilation duct body 1. The sealing layer 2 material is cut to a suitable size, and a special sealing adhesive is applied to one side of the sealing layer 2 material and the inner wall surface of the reinforcing layer 3. This adhesive should have good sealing performance and compatibility with the sealing layer 2 material. The sealing layer 2 material is pasted onto the inner wall of the reinforcing layer 3. The reinforcing layer 3 is usually made of fiber material, such as glass fiber, carbon fiber or aramid fiber, and the sealing layer 2 is usually made of plastic material such as polytetrafluoroethylene (PTFE).

[0029] Through the reinforcement layer 3 and the sealing layer 2, the structural strength and stability of the ventilation duct body 1 are improved by the reinforcement layer 3, which can withstand the pressure of the airflow inside the ventilation duct and various forces that can be applied from the outside. The sealing layer 2 can effectively prevent air from leaking from the inside of the ventilation duct to the external environment, or prevent dust, moisture and other external substances from entering the inside of the ventilation duct.

[0030] In use, the selected reinforcing layer 3 material is cut to the dimensions of the ventilation duct's inner wall, completely covering the portion requiring reinforcement. Then, adhesive is evenly applied to one side of the reinforcing layer 3 material and the inner wall surface of the ventilation duct body 1. The adhesive is typically a high-temperature resistant, moisture-resistant product with good adhesion, such as epoxy resin adhesive. After application, the reinforcing layer 3 material is carefully adhered to the inner wall of the ventilation duct body 1. The sealing layer 2 material is cut to a suitable size, and a specialized sealing adhesive is applied to one side of the sealing layer 2 material and the inner wall surface of the reinforcing layer 3. This adhesive must have good sealing performance and compatibility with the sealing layer 2 material. The sealing layer 2 material is then adhered to the inner wall of the reinforcing layer 3. The rigid plastic collar 51 is fixed to one end of the ventilation duct body 1 via heat fusion. By fixing the rigid plastic collar 51 to the side of the ventilation pipe body 1 near the flange 4, a firm installation is ensured. At the same time, a sliding groove 56 and a fixing hole 58 are opened on the flange 4, and the sliding block 55 is fitted inside the flange 4 so that the locking block 54 corresponds to the locking groove 52 on the rigid plastic collar 51. The ventilation pipe body 1 is close to the flange 4, so that the locking groove 52 on the rigid plastic collar 51 is aligned with the locking block 54. Then the locking block 54 is inserted into the locking groove 52. At this time, the sliding block 55 will slide inside the flange 4 as the locking block 54 is inserted and enters the corresponding sliding groove 56. Thus, it is threaded to the center of the sliding block 55 by the threaded bolt 57 and screwed into the corresponding fixing hole 58. The sliding block 55 is fixed in the sliding groove 56 by the threaded bolt 57, thereby realizing the fixed connection between the ventilation pipe body 1 and the flange 4.
