Description

Technical Field

[0001] This application relates to the field of fire protection equipment technology, and in particular to a fixing device for fire protection equipment and a ship. Background Technology

[0002] Firefighting at sea is a crucial aspect of maritime safety, with fire extinguishers typically used as the core rescue equipment. However, a suitable solution for securing fire extinguishers on ships remains elusive, especially for wheeled fire extinguishers like vehicle-mounted ones. When the ship encounters rough seas and experiences rolling and pitching, the fire extinguishers are prone to instability, eventually capsizing and rolling with the ship's movement, posing a potential threat to the safety of crew and equipment. Currently, firefighting equipment is often secured with knotted ropes. However, this method is insufficient to stabilize the equipment in rough seas, and untying the knots before using the equipment takes time, impacting the timeliness of firefighting efforts. Utility Model Content

[0035] This application discloses a fixing device for fire-fighting equipment, which can be applied to ships to secure the fire-fighting equipment to the ship.

[0036] To facilitate understanding of the structure of the fixing device for fire-fighting equipment and the vessel, the fixing device for fire-fighting equipment and the vessel will be further described below with reference to embodiments and accompanying drawings. It should be noted that the following description is merely illustrative and not a specific limitation of this application.

[0037] This application provides a ship, including a hull, fire-fighting equipment 1 (e.g., fire extinguisher, fire extinguisher canister, etc.), and a fixing device 2 for the fire-fighting equipment (see...). Figure 1 The fixing device 2 is fixedly connected to the hull to secure the fire-fighting equipment 1 to the hull. For details, please refer to [link / reference needed]. Figures 1 to 4 The fire-fighting equipment 1 includes an equipment body 11 and a support leg 12. The support leg 12 is used to support the equipment body 11. The fixing device 2 includes a fixing bracket 21 and a rotary switch 22. The fixing bracket 21 is fixedly connected to the hull. One end of the fixing bracket 21 is provided with a first positioning groove 2111. The first positioning groove 2111 has a first opening 2111a and a second opening 2111b that are perpendicular to each other (see...). Figure 4 and Figure 6 The second opening 2111b extends through both sides of the fixed bracket 21. The support foot 12 is used to enter the first positioning groove 2111 through the first opening 2111a and pass through the second opening 2111b. The other end of the fixed bracket 21 is provided with a second positioning groove 2141 with an opening facing the device body 11. The device body 11 is movably mounted in the second positioning groove 2141. The second positioning groove 2141 is used to limit the displacement of the device body 11 along the direction of the second opening 2111b. The rotary switch 22 is rotatably connected to the fixed bracket 21 to open or close the first opening 2111a.

[0038] The fire-fighting equipment fixing device 2 and the ship of this application are fixedly connected to the hull by a fixing bracket 21, and the first opening 2111a of the first positioning groove 2111 is opened or closed by rotating a rotary switch 22 relative to the fixing bracket 21. For example, when the first opening 2111a is open, the support leg 12 of the fire-fighting equipment 1 can enter the first positioning groove 2111 and pass through the second opening 2111b. By rotating the rotary switch 22 to close the first opening 2111a, the support leg 12 is locked in the fixing device 2. At the same time, the equipment body 11 of the fire-fighting equipment 1 is positioned by the second positioning groove 2141 to limit the displacement of the equipment body 11 along the direction of the second opening 2111b, thereby enabling the fire-fighting equipment 1 to remain stable relative to the ship and improving the stability of the fire-fighting equipment 1 on the ship. After the support leg 12 is locked to the fixing device 2, when the fire-fighting equipment 1 needs to be removed, the first opening 2111a is opened by rotating the rotary switch 22, and the support leg 12 can leave the first positioning groove 2111 through the first opening 2111a, thereby realizing the quick unlocking and removal of the fire-fighting equipment 1. Using the fixing device 2 of this embodiment, the opening and closing of the first opening 2111a can be controlled by rotating the rotary switch 22, which facilitates the adjustment of the locking state of the fixing device 2 on the support leg 12, so that the support leg 12 can enter or leave the first positioning groove 2111. This makes the removal and placement of the support leg 12 relative to the fixing device 2 more convenient and faster, thereby realizing the rapid removal and placement of the fixing device 2 and improving the timeliness of fire rescue.

[0039] Please combine Figures 3 to 6 In some embodiments, the first opening 2111a is vertically upward (i.e., the first opening 2111a faces the deck away from the hull), and the fixed bracket 21 has a horizontally extending groove 2112 on the side near the fire-fighting equipment 1, with one end of the groove 2112 passing through the fixed bracket 21. The rotary switch 22 includes a first rotating arm 221 and a second rotating arm 222. The first rotating arm 221 extends along the height direction of the fixed bracket 21, and one end of the second rotating arm 222 is connected to the first rotating arm 221. The other end of the second rotating arm 222 passes through the groove 2112. The first rotating arm 221 is used to drive the second rotating arm 222 to rotate relative to the fixed bracket 21. When the second rotating arm 222 rotates to disengage from the groove 2112, the first opening 2111a is opened. When the second rotating arm 222 rotates to enter the groove 2112, the first opening 2111a is closed.

[0040] In this way, by adjusting the rotation of the first rotating arm 221 relative to the fixed bracket 21, the second rotating arm 222 is driven to move relative to the slide groove 2112, so that the second rotating arm 222 moves to disengage from the slide groove 2112 to open the first opening 2111a. At this time, the support foot 12 can leave the first positioning groove 2111 through the first opening 2111a. At the same time, by controlling the device body 11 to disengage from the second positioning groove 2141, the fire-fighting equipment 1 can be separated from the fixed device 2 to meet the needs of quick access to the fire-fighting equipment 1. Thus, in the event of a fire, the fire-fighting equipment 1 can be quickly removed for fire extinguishing and timely fire rescue. After the fire-fighting equipment 1 is used, the support leg 12 is placed into the first positioning groove 2111 through the first opening 2111a. By rotating the first rotating arm 221, the second rotating arm 222 is driven into the slide groove 2112 to close the first opening 2111a. At this time, the support leg 12 is locked in the first positioning groove 2111. The inner wall of the first positioning groove 2111 and the second rotating arm 222 limit the movement of the support leg 12 in two directions perpendicular to the second opening 2111b. At the same time, by inserting the equipment body 11 into the second positioning groove 2141, the displacement of the equipment body 11 in the direction of the second opening 2111b is limited, thereby keeping the fire-fighting equipment 1 stable relative to the hull and ensuring the safety of the fire-fighting equipment 1 and the crew.

[0041] Due to the directional restriction of the first opening 2111a, the fire-fighting equipment 1 can be lifted along the height direction of the fixed bracket 21 by manual or mechanical means so that the support leg 12 leaves the first positioning groove 2111. Alternatively, for the vehicle-mounted fire-fighting equipment 1, the support leg 12 can also be moved out of the first positioning groove 2111 with the assistance of the rollers 13 at its bottom.

[0042] For example, the support leg 12 includes a support frame 121, a first leg 122, a second leg 123, and a connecting rod 124. One end of the connecting rod 124 is connected to the first leg 122, and the other end of the connecting rod 124 is connected to the second leg 123. The connecting rod 124 is used to enter the first positioning groove 2111 through the first opening 2111a. The fixed bracket 21 is located between the first leg 122 and the second leg 123. The support frame 121 is connected to the first leg 122 and the second leg 123. The equipment body 11 rests on the support frame 121. The fire-fighting equipment 1 also includes a roller 13. The roller 13 is connected to the side of the support frame 121 away from the connecting rod 124. The first rotating arm 221 is located on the side of the second rotating arm 222 away from the fire-fighting equipment 1. Thus, when the fire-fighting equipment 1 needs to be removed, firstly, the first opening 2111a is opened, and then the equipment body 11 is pressed downwards with the roller 13 as the center. This causes the equipment body 11 to flip downwards with the roller 13 as the fulcrum, moving it away from the second positioning groove 2141. At the same time, the support leg 12 rotates counterclockwise with the roller 13 as the center. At this time, the ends of the first support leg 122 and the second support leg 123 away from the roller 13 are lifted upwards, causing the connecting rod 124 to disengage from the first positioning groove 2111 through the first opening 2111a, thereby separating the fire-fighting equipment 1 from the fixing device 2. Then, the rolling of the roller 13 makes it easy to move the fire-fighting equipment 1 to the target working position. It can be seen that the method of using the roller 13 to assist the support leg 12 in moving out of the first positioning groove 2111 is more time-saving and labor-saving, making the removal and placement of the fire-fighting equipment 1 faster and simpler. In addition, the fixed bracket 21 is disposed between the first leg 122 and the second leg 123. When the positioning of the equipment body 11 by the second positioning groove 2141 fails, the fixed bracket 21 can block the movement of the first leg 122 and the second leg 123 along the direction of the second opening 2111b, thereby limiting the movement of the fire-fighting equipment 1 along the direction of the second opening 2111b and preventing the fire-fighting equipment 1 from leaving the fixed device 2 along the direction of the second opening 2111b.

[0043] In some embodiments, the fire-fighting equipment 1 also includes a handrail 14, which is connected to the support frame 121 and extends to the top of the equipment body 11 along its height direction. By providing the handrail 14, it can assist in grasping the fire-fighting equipment 1 during movement and retrieval, thereby further improving the retrieval and placement efficiency of the fire-fighting equipment 1.

[0044] In some embodiments, the rotary switch 22 further includes a third rotary arm 223, which is connected to the end of the second rotary arm 222 away from the first rotary arm 221 and located outside the first positioning groove 2111. The extension direction of the third rotary arm 223 is set at an angle to the extension direction of the slide groove 2112.

[0045] In this way, when the second rotating arm 222 passes through the slide 2112, it can be connected to the fixed bracket 21 by the third rotating arm 223 to restrict the movement of the second rotating arm 222 along its own length direction, improve the locking stability of the fixed device 2 on the support foot 12, and avoid the situation where the rotary switch 22 moves relative to the slide 2112 along the length direction of the second rotating arm 222 to disengage from the slide 2112 when the ship is rocking, causing the first opening 2111a to open and affecting the stability of the support foot 12 in the first positioning groove 2111.

[0046] Optionally, the angle formed by the extension direction of the third rotating arm 223 and the extension direction of the slide 2112 can be 90°, in which case the third rotating arm 223 extends toward or away from the deck. Alternatively, the angle formed by the extension direction of the third rotating arm 223 and the extension direction of the slide 2112 can be an acute angle or an obtuse angle.

[0047] Optionally, to facilitate the entry and exit of the support leg 12 into the first positioning groove 2111, the first positioning groove 2111 will reserve a certain amount of space for the support leg 12 to move. However, due to the turbulence and swaying of the ship during navigation, if the size of the support leg 12 and the size of the first positioning groove 2111 do not fit precisely, the support leg 12 will move relative to the first positioning groove 2111, causing the support leg 12 to collide with the fixed bracket 21 or the second rotating arm 222, resulting in wear and damage to the structure. Based on this, the inner wall of the first positioning groove 2111 is provided with a first buffer pad 23, and / or the side of the second rotating arm 222 facing the first positioning groove 2111 is provided with a first buffer pad 23. That is, in some examples, the inner wall of the first positioning groove 2111 and the second rotating arm 222 can be provided with the first buffer pad 23 at the same time, or only the inner wall of the first positioning groove 2111 is provided with the first buffer pad 23, or only the side of the second rotating arm 222 facing the first positioning groove 2111 is provided with the first buffer pad 23.

[0048] In this way, by setting the first buffer pad 23, on the one hand, it can buffer the instantaneous impact force of the relative movement between the support leg 12 and the fixing device 2, achieving the effect of anti-collision protection and reducing the risk of collision damage. On the other hand, by utilizing the elastic deformation capacity of the first buffer pad 23, while ensuring the convenience of the support leg 12 entering and exiting the first positioning groove 2111, it can fill the gap between the support leg 12 and the fixing device 2, reducing the movement space of the support leg 12 relative to the first positioning groove 2111. This helps to reduce the distance the support leg 12 moves relative to the fixing device 2 due to the swaying of the hull, making the relative position of the fire-fighting equipment 1 and the fixing device 2 more stable.

[0049] Optionally, the first cushioning pad 23 can be made of any of the following materials: foam plastic, sponge, rubber, silicone, or polyurethane. This ensures the cushioning and absorption capacity of the first cushioning pad 23.

[0050] Understandably, in some other embodiments, the direction of the first opening 2111a may also be from the fixed frame to the fire-fighting equipment 1. In this case, the slide 2112 may be provided on the side of the fixed bracket 21 that is close to the deck and the side that is far from the deck. The third rotating arm 223 of the rotary switch 22 extends toward the direction close to the deck and passes through the slide 2112. The rotary switch 22 also includes a fourth rotating arm. The fourth rotating arm is connected to the end of the third rotating arm 223 that is far from the second rotating arm 222 and is located outside the first positioning groove 2111. The fourth rotating arm extends in the horizontal direction.

[0051] In some embodiments, considering that the rotary switch 22 controls the opening 2111a by rotating the first rotating arm 221, and that a vertical rod-shaped rotating arm is inconvenient to hold and operate, the rotary switch 22 further includes a handle 224, which is located at the end of the first rotating arm 221 away from the second rotating arm 222. This facilitates control of the movement of the rotary switch 22 and improves the ease of adjustment of the rotary switch 22.

[0052] Optionally, the handle 224 can be a rod-like structure extending horizontally, or it can be any of the following: a block-like structure or a ring-like structure. This makes it easier for a person to hold and operate, making the movement control of the rotary switch 22 more convenient.

[0053] Optionally, the handle 224 and the first rotating arm 221 can be connected by any of the following methods: welding, threaded connection, or interference fit snap-fit. This can improve the reliability of the connection between the handle 224 and the first rotating arm 221.

[0054] In some embodiments, the fixing device 2 further includes a safety buckle 24, which is mounted on the first rotating arm 221 of the rotary switch 22. The safety buckle 24 is movably connected to the fixing bracket 21 to restrict the rotational movement of the rotary switch 22 or to release the restriction on the rotational movement of the rotary switch 22.

[0055] This improves the stability of the rotary switch 22 relative to the fixed bracket 21, thereby enhancing the reliability of the fixing device 2. It also prevents the rotary switch 22 from rotating due to wind and waves during the ship's voyage, or from rotating due to accidental contact, which could cause the first opening 2111a to be opened incorrectly, thus affecting the locking reliability of the fixing device 2 on the support foot 12.

[0056] Optionally, the fixed bracket 21 is provided with a latching groove, and the safety buckle 24 is rotatably connected to the first rotating arm 221 of the rotary switch 22. One end of the safety buckle 24 can extend movably into the latching groove. The safety buckle 24 is used to disengage from the latching groove when the rotary switch 22 moves along the height direction of the fixed bracket 21, thereby releasing the rotation restriction on the rotary switch 22. This makes the use of the safety buckle 24 more convenient and facilitates switching between the state where the rotary switch 22's rotational movement is restricted and the state where the rotation restriction is released, thereby improving the ease of operation for taking out and placing the fire-fighting equipment 1 while ensuring the reliability of the fixing device 2.

[0057] For example, by lifting the rotary switch 22 upwards, one end of the safety buckle 24 moves upwards. Since the other end of the safety buckle 24 is restricted by the latching groove, the safety buckle 24 rotates at the position connected to the rotary switch 22. As the rotary switch 22 moves along the height direction of the fixed bracket 21, the safety buckle 24 is disengaged from the latching groove by the rotary switch 22, thereby releasing the rotation restriction on the rotary switch 22. At this time, the rotary switch 22 can rotate relative to the fixed bracket 21, so that the first opening 2111a switches between the open and closed states. When it is necessary to restrict the rotational movement of the rotary switch 22, the rotary switch 22 is controlled to move downwards and the safety buckle 24 is manually inserted into the latching groove, so that the rotary switch 22 cannot rotate under the restriction of the safety buckle 24, thereby improving the movement reliability of the rotary switch 22.

[0058] Understandably, in other examples, the safety catch 24 can also disengage from the latch slot by pressing the rotary switch 22 downwards.

[0059] It should be noted that the dimensions of the slide 2112 need to provide sufficient space for the rotary switch 22 to move along the height direction of the fixed bracket 21, so as to ensure the reliability of the fixing device 2.

[0060] Understandably, in other embodiments, the safety buckle 24 may also be a U-shaped structure with a central groove, which positions the first rotating arm 221. The U-shaped structure engages with the latching slot to restrict the rotary switch 22. Alternatively, the safety buckle 24 may be fixed to the first rotating arm 221, and the connection between the safety buckle 24 and the fixed bracket 21 may be a threaded connection or magnetic adsorption, etc., to facilitate switching the restriction state of the rotary switch 22.

[0061] In some embodiments, the fixed bracket 21 includes a base 211, a first connecting part 212, a second connecting part 213, and a fixed support part 214. The first connecting part 212 extends along the height direction of the fire-fighting equipment 1. The base 211 is connected to the bottom of the first connecting part 212, and the second connecting part 213 is connected to the top of the first connecting part 212. Both the base 211 and the second connecting part 213 are located on the side of the first connecting part 212 closest to the fire-fighting equipment 1. The fixed support part 214 is connected to the side of the second connecting part 213 closest to the fire-fighting equipment 1. A snap-fit ​​groove is provided in the second connecting part 213. A first positioning groove 2111 and a sliding groove 2112 are provided in the base 211. A second positioning groove 2141 is provided in the fixed support part 214. The first connecting part 212 and / or the base 211 are fixedly connected to the hull. A rotary switch 22 passes through the first connecting part 212 and is rotatable relative to the first connecting part 212.

[0062] In this way, the base 211, the second connecting part 213, and the fixed support part 214 are all located on the side of the first connecting part 212 closer to the fire-fighting equipment 1, which facilitates the movement of the fire-fighting equipment 1 relative to the fixed bracket 21 and is conducive to the removal and placement of the fire-fighting equipment 1. At the same time, by setting the rotary switch 22 through the first connecting part 212, on the one hand, the rotary switch 22 can be positioned through the first connecting part 212, so as to keep the relative position of the rotary switch 22 and the fixed bracket 21 stable, improve the structural stability of the fixing device 2, and avoid the situation where the fixing device 2 falls apart due to the swaying of the ship. On the other hand, it is convenient to control the movement of the rotary switch 22 relative to the fixed bracket 21, making the operation of the rotary switch 22 more convenient.

[0063] It should be noted that the first connecting part 212 and / or base 211 mentioned above are fixedly connected to the hull. In some examples, the fixed bracket 21 can be fixedly connected to the hull through the first connecting part 212 or the base 211. Alternatively, in other examples, the fixed bracket 21 can be fixedly connected to the hull through both the first connecting part 212 and the base 211.

[0064] Understandably, in other embodiments, the rotary switch 22 may also be disposed on the outer periphery of the fixed bracket 21 and located on the side of the first connecting part 212 near the fire-fighting equipment 1. In this case, the snap-fit ​​groove is disposed on the side of the first connecting part 212 near the fire-fighting equipment 1, and the height of the first rotating arm 221 is lower than the height of the first connecting part 212, so as to ensure that the first rotating arm 221 can move along the height direction of the fixed bracket 21.

[0065] Optionally, the first connecting portion 212 has a hollow portion, a first movable hole, and a second movable hole. The hollow portion extends along the height direction of the fire-fighting equipment 1. The first movable hole is located at the bottom of the first connecting portion 212 and communicates with the hollow portion. The base 211 has a third movable hole corresponding to the first movable hole, and the third movable hole communicates with the first movable hole and the first positioning groove 2111. The second movable hole is located at the top of the first connecting portion 212 and communicates with the hollow portion. The first rotating arm 221 of the rotary switch 22 is movably installed in the hollow portion. The first rotating arm 221 extends out of the hollow portion through the second movable hole, and the first rotating arm 221 is located at the end of the second connecting portion 213 away from the fixed support portion 214. The opening of the snap-fit ​​groove faces the first rotating arm 221. The end of the second rotating arm 222 away from the slide groove 2112 passes through the second movable hole and the first movable hole in sequence. This ensures the relative position of the rotary switch 22 and the fixed bracket 21 while meeting the requirements for the rotational movement of the rotary switch 22 and its movement along the height direction of the fixed bracket 21.

[0066] Optionally, the first movable hole extends along the direction of the second opening 2111b to at least one end through the first connecting portion 212, and the third movable hole extends along the direction of the second opening 2111b to at least one end through the base 211. The first movable hole, the third movable hole, and the sliding groove 2112 are located on the same side, and the first movable hole and the third movable hole have reserved space along the height direction of the first connecting portion 212 for the second rotating arm 222 to move. This ensures the reliability of the movement of the rotary switch 22 relative to the fixed bracket 21.

[0067] In some embodiments, the inner wall of the second positioning groove 2141 is provided with a second buffer pad 25. This can prevent the fixed support part 214 from directly contacting the equipment body 11, reduce the friction between the fixed support part 214 and the equipment body 11, and buffer the relative movement between the equipment body 11 and the fixed support part 214, thereby reducing the wear of the equipment body 11 and the fixed support part 214 when picking up and putting down the fire-fighting equipment 1.

[0068] Optionally, the second cushioning pad 25 can be made of any of the following materials: foam, sponge, rubber, silicone, or polyurethane. This ensures the cushioning and absorption capacity of the second cushioning pad 25.

[0069] Optionally, considering that the corners of the fixed bracket 21 and the rotary switch 22 are usually very sharp, and that crew members may easily lose their balance and bump into the fixed device 2 when the ship is rocking, resulting in cuts from the sharp corners, the fixed device 2 also includes multiple protective sleeves. The protective sleeves are set at various corners of the fixed device 2, especially at the corners of the first connecting part 212, the second connecting part 213, the first rotating arm 221, and the handle part 224, thereby making the fixed device 2 safer to use and protecting the safety of the crew.

[0070] Alternatively, the protective case can be made of any of the following materials: foam, sponge, pearl cotton, or silicone.

[0071] To facilitate reading and understanding, a simple example of the use of fixing device 2 is provided below:

[0072] When it is necessary to remove the fire equipment 1, firstly, lift the first rotating arm 221 upwards using the handle 224. The first rotating arm 221 drives the safety buckle 24 to disengage from the buckle slot, thereby releasing the restriction of the rotational movement of the rotary switch 22 by the safety buckle 24. Then, the first rotating arm 221 is rotated horizontally 90° counterclockwise using the handle 224, thereby driving the second rotating arm 222 to rotate out of the disengagement groove 2112 and opening the first opening 2111a. Then, downward pressure is applied to the handrail 14 to make the fire equipment 1 flip downwards around the roller 13, so that the equipment body 11 disengages from the second positioning groove 2141 and the support leg 12 leaves the first positioning groove 2111, thereby completing the separation of the fire equipment 1 from the fixing device 2, so that the fire equipment 1 can be quickly put into use.

[0073] When it is necessary to fix the fire-fighting equipment 1, the fire-fighting equipment 1 is moved close to the fixing device 2 by the handrail 14 and rollers 13. The support leg 12 is raised by pressing down the handrail 14. The support leg 12 is moved above the first opening 2111a by the rollers 13. The handrail 14 is released to lower the support leg 12 so that the support leg 12 can enter the first positioning groove 2111 through the first opening 2111a. At the same time, the equipment body 11 enters the second positioning groove 2141. Then, the first rotating arm 221 is rotated horizontally by 90° clockwise by the handle 224 so that the second rotating arm 222 rotates into the slide groove 2112 to close the first opening 2111a and complete the stable connection between the fire-fighting equipment 1 and the fixing device 2. Then, the safety buckle 24 is inserted into the buckle groove to limit the rotation movement of the rotary switch 22 to improve the reliability of the fixing device 2 and make the fire-fighting equipment 1 more stable relative to the hull.

[0074] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
