Description

Technical Field

[0001] This utility model relates to the field of fireproof windbreak technology, specifically to low-wind-resistance marine fireproof windbreak guide vanes. Background Technology

[0002] Fire dampers are a common type of marine fire-fighting equipment. They are shut-off devices suitable for ducted ventilation. Fire dampers must be installed in the critical ventilation ducts between two different fire zones to prevent the spread of fire. The operation of fire dampers can vary: they can be purely mechanical, pneumatic, or electric, etc.

[0003] In ship ventilation systems, fire-resistant dampers are crucial safety devices used to prevent the spread of flames and smoke through ventilation ducts during a fire. Existing fire-resistant damper guide vanes typically employ a static sealing structure; however, under high-temperature environments, the sealing material is prone to deformation, leading to seal failure and reduced fire-resistant performance. Therefore, low-drag marine fire-resistant damper guide vanes are proposed to address the aforementioned problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a low-resistance marine fireproof windbreak guide vane, which has advantages such as significant fireproof effect and solves the problems mentioned in the background technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] The low wind resistance marine fireproof windbreak guide vane includes a blade body, a windbreak body disposed outside the blade body, and a cover plate detachably connected to the outside of the blade body. The blade body is provided with a dynamic sealing structure extending into its interior, and the blade body is provided with a transmission structure for use in conjunction with the dynamic sealing structure.

[0007] The dynamic sealing structure includes an abutment plate that is slidably connected to the inside of the blade body and extends to the outside of it, and a sponge block disposed inside the blade body. Overflow holes are provided at the top and bottom of the blade body.

[0008] The transmission structure includes a transmission block disposed inside the blade body. An abutment rod is disposed through the inside of the transmission block. One end of the abutment rod is rotatably connected to a roller extending into the inside of the transmission block. The inside of the transmission block is provided with a transmission groove that matches the roller. A pressing plate is fixedly connected to the end of the abutment rod away from the roller.

[0009] Furthermore, there are two sponge blocks, which are symmetrically distributed vertically on the inner wall of the blade body and located on one side of the overflow hole.

[0010] Furthermore, there are multiple overflow holes, which are distributed at equal intervals on the upper and lower sides of the blade body.

[0011] Furthermore, the transmission groove is inclined, and the extrusion plate is located on the side of the sponge block away from the blade body.

[0012] Furthermore, there are two sets of blade bodies, both sets of blade bodies are rotatably connected to the inside of the damper body, and there are two sets of dynamic sealing structures, with one side of each set of dynamic sealing structures located on the opposite side of the two sets of blade bodies.

[0013] Furthermore, the number of transmission blocks, transmission grooves, rollers, abutment rods, and extrusion plates are all in two sets, and a fixed cylinder is fixedly connected between the two sets of transmission blocks.

[0014] Furthermore, a connecting rod is fixedly connected between one end of the fixed cylinder and the abutment plate, and an abutment spring is fixedly connected between the other end of the fixed cylinder and the inner wall of the blade body.

[0015] Furthermore, the extrusion plate is externally fixedly connected to a slider extending into the interior of the blade body, and the interior of the blade body is provided with a sliding groove that matches the slider, and the slider and the sliding groove are slidably connected.

[0016] Compared with the prior art, this utility model provides a low-wind-resistance marine fireproof windbreak guide vane, which has the following beneficial effects:

[0017] 1. When the guide vanes of this low-drag marine fireproof windbreak slide within the blade body under external force through the abutment plate, they will compress the sponge block through the transmission structure. The sponge block has a porous structure and stores fire retardant inside. After being compressed, the fire retardant will flow out from the overflow hole and form a fireproof liquid film between the blade body and the inner wall of the windbreak body, which plays a sealing role and effectively prevents flames and high-temperature gases from spreading through the gap between the blade and the windbreak body, thus improving the fireproof effect.

[0018] 2. When the guide vanes of this low-drag marine fireproof windbreak are subjected to external force through the transmission block, the rollers roll in the transmission groove due to the inclined setting of the transmission groove. The horizontal movement of the transmission block is converted into the vertical movement of the extrusion plate through the abutment rod. This allows a large output force to be obtained with a small input force, thereby more effectively squeezing the sponge block, allowing the fire retardant to flow out smoothly, achieving the sealing function, and improving the fireproof performance and safety of the windbreak.

Detailed Implementation

[0025] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1 to 5 The low wind resistance marine fireproof windbreak guide vane in this embodiment includes a blade body 1, a windbreak body 2 disposed outside the blade body 1, and a cover plate 3 detachably connected to the outside of the blade body 1. The blade body 1 is provided with a dynamic sealing structure 4 extending into its interior, and the blade body 1 is provided with a transmission structure 5 for use in conjunction with the dynamic sealing structure 4.

[0027] The dynamic sealing structure 4 includes an abutment plate 41 that is slidably connected to the inside of the blade body 1 and extends to the outside of it, and a sponge block 43 disposed inside the blade body 1. Overflow holes 42 are provided at the top and bottom of the blade body 1.

[0028] Specifically, there are two sponge blocks 43, which are symmetrically distributed vertically on the inner wall of the blade body 1 and located on one side of the overflow hole 42. The cover plate 3 facilitates the timely replenishment of fire retardant to the sponge blocks 43.

[0029] It should be noted that there are multiple overflow holes 42, which are distributed at equal intervals on the upper and lower sides of the blade body 1.

[0030] It is worth mentioning that there are two sets of blade bodies 1, both of which are rotatably connected to the interior of the damper body 2. There are also two sets of dynamic sealing structures 4, with one side of each set distributed on the opposite side of the two sets of blade bodies 1. When the abutment plate 41 slides within the blade body 1 under external force, it compresses the sponge block 43 through the transmission structure 5. The sponge block 43 has a porous structure and stores fire retardant inside. After being compressed, the fire retardant flows out from the overflow hole 42, forming a fireproof liquid film between the blade body 1 and the inner wall of the damper body 2, which acts as a seal and effectively prevents flames and high-temperature gases from spreading through the gap between the blade body 1 and the damper body 2, thus improving the fireproof effect.

[0031] In addition, a mounting box is fixedly connected to the top of the damper body 2. The mounting box is located on the top of the damper body 2 and contains an actuator for controlling the rotation and opening / closing of the blade body 1. The actuator is a conventional technology known to the public in the prior art, so its specific structural composition and working principle will not be described in detail here.

[0032] In this embodiment, the transmission structure 5 includes a transmission block 53 disposed inside the blade body 1. A connecting rod 56 is disposed through the inside of the transmission block 53. One end of the connecting rod 56 is rotatably connected to a roller 55 extending into the inside of the transmission block 53. The inside of the transmission block 53 is provided with a transmission groove 54 adapted to the roller 55. A pressing plate 57 is fixedly connected to the end of the connecting rod 56 away from the roller 55. When the transmission block 53 is subjected to an external force from the connecting plate 41, the roller 55 rolls in the transmission groove 54 due to the inclined arrangement of the transmission groove 54. The horizontal movement of the transmission block 53 is converted into the vertical movement of the pressing plate 57 through the connecting rod 56. By utilizing the principle of the inclined plane, a large output force can be obtained with a small input force, thereby more effectively squeezing the sponge block 43, allowing the fire retardant to flow out smoothly and achieving the sealing function.

[0033] The transmission groove 54 is inclined, and the extrusion plate 57 is located on the side of the sponge block 43 away from the blade body 1. The rolling cooperation between the roller 55 and the transmission groove 54 reduces the friction during the movement, making the transmission smoother and more stable.

[0034] Specifically, there are two sets of transmission blocks 53, transmission grooves 54, rollers 55, abutment rods 56 and extrusion plates 57, and a fixed cylinder 52 is fixedly connected between the two sets of transmission blocks 53.

[0035] It should be noted that a connecting rod 51 is fixedly connected between one end of the fixed cylinder 52 and the abutment plate 41, and an abutment spring 58 is fixedly connected between the other end of the fixed cylinder 52 and the inner wall of the blade body 1. The abutment spring 58 enables the entire transmission structure 5 to have a reset function. When the external force disappears, the elastic force of the abutment spring 58 will cause the transmission block 53, the abutment plate 41, and other components to return to their initial positions, preparing for the next sealing action and improving the automation level and response speed of the equipment.

[0036] It is worth mentioning that the extrusion plate 57 is externally fixedly connected to a slider 6 extending into the interior of the blade body 1. The interior of the blade body 1 has a groove 7 that matches the slider 6, and the slider 6 and the groove 7 are slidably connected. This slidable connection between the slider 6 and the groove 7 provides precise guidance for the movement of the extrusion plate 57. Under the action of the transmission structure 5, the extrusion plate 57 needs to move vertically in a specific direction to extrude the sponge block 43. The sliding of the slider 6 within the groove 7 restricts the movement trajectory of the extrusion plate 57, ensuring it can only move along the direction of the groove 7. This prevents the extrusion plate 57 from deviating or wobbling during movement, ensuring the accuracy and stability of the extrusion action, thereby ensuring effective extrusion of the sponge block 43 and allowing the fire retardant to flow out normally to achieve a sealing function.

[0037] The working principle of the above embodiments is as follows:

[0038] During normal ventilation, the blade body 1 is in the open state, with low wind resistance. The dynamic sealing structure 4 and transmission structure 5 are in a non-working state, the abutment plate 41 is separated from the inner wall of the damper body 2, and the fire retardant in the sponge block 43 is not squeezed. In the event of a fire, the controller activates the actuator, which rotates the blade body 1 to the closed position. The abutment plate 41 slides inside the blade body 1 and moves closer to the inner wall of the damper body 2. The transmission structure 5 is activated, and the movement of the abutment plate 41 is transmitted to the fixed cylinder 52 through the connecting rod 51, which drives the transmission block 53 to move. The roller 55 inside the transmission block 53 rolls in the inclined transmission groove 54, converting the horizontal movement into the vertical movement of the extrusion plate 57, which applies pressure to the sponge block 43. The fire retardant is squeezed out from the sponge block 43 and flows out through the overflow hole 42, forming a fire-retardant liquid film between the blade body 1 and the inner wall of the damper body 2, which acts as a seal to prevent the spread of flames and high-temperature gases. After the external force disappears, the abutment spring 58 resets the transmission block 53 and the abutment plate 41, preparing for the next sealing action.

[0039] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that achieves the desired beneficial effect can be implemented. Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer that performs control functions. Those skilled in the art can control the electrical components through simple programming, and the existing disclosed power connection technologies are common knowledge in the field. Therefore, this embodiment will not elaborate further on their specific structural composition and working principles.
