Description

Technical Field

[0001] This invention relates to the field of fire-fighting auxiliary equipment, specifically to a fire hose fixing device with an obstacle avoidance support rod. Background Technology

[0002] Fire hoses, also known as fire hoses or fire extinguishing hoses, are core tubular equipment used in fire fighting and emergency rescue scenarios to transport high-pressure water or flame-retardant liquids such as foam. Currently, most mainstream products adopt a composite structure with a high-strength polyester fiber or nylon braided outer layer and a pressure-resistant inner lining such as rubber or polyurethane (PU). They are available in multiple grades according to working pressure, such as 0.8MPa, 1.0MPa, 1.3MPa, and 1.6MPa, and in common specifications according to inner diameter, such as 50mm, 65mm, and 80mm. The standard length of a single hose is mostly 20 meters. Both ends are equipped with standardized metal connectors. They can be directly connected to fire hydrants, fire pumps, and fire nozzles to complete fire fighting operations, or multiple hoses can be spliced ​​together to extend the water delivery distance. With special accessories such as water distributors, hose bridges, and hose hooks, they can be adapted to various complex fire environments such as high-rise buildings, industrial parks, and open-air factories. They are essential basic fire protection facilities in various industrial sites and civil buildings.

[0003] When using existing fire hoses for firefighting operations in high-rise buildings, the fire hoses are difficult to secure and use when they are carried out through windows. This causes the fire hoses to swing excessively at high altitudes, making it difficult for firefighters to handle them. In addition, some buildings have other facilities installed in front of the windows, which can easily cause the fire hoses to enter the building through the windows, making operation difficult. Summary of the Invention

[0004] The purpose of this invention is to provide a fire hose fixing device with an obstacle avoidance strut to solve the problem of inconvenience in using fire hoses in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a fire hose fixing device with an obstacle avoidance strut, comprising a fixing shaft and an obstacle avoidance strut, wherein a fixing clamp is fixedly connected to the fixing shaft, and further comprising: a fixing mechanism disposed on the fixing shaft and the fixing clamp for binding and fixing the fire hose, the fixing mechanism comprising a plurality of friction strips fixedly disposed on the side wall of the fixing shaft, both ends of the fixing shaft being fixedly disposed with limiting angle steel, and a threaded shaft being screwed onto the fixing clamp; a rope is bound to the fire hose, and the other end of the rope is bound to the fixing shaft; an obstacle avoidance mechanism disposed on the obstacle avoidance strut, the obstacle avoidance mechanism comprising a U-shaped support head fixedly disposed at the end of the obstacle avoidance strut.

[0006] Furthermore, the fixing mechanism also includes several anti-slip patterns provided on the inner wall of the limiting angle steel.

[0007] Furthermore, the fixing mechanism also includes a threaded sleeve fixedly disposed at one end of the fixing clamp, and the threaded shaft is screwed onto the fixing clamp through the threaded sleeve.

[0008] Furthermore, the fixing mechanism also includes a support pad fixedly disposed at the other end of the fixing clamp, and a clamping block is fixedly disposed at the end of the threaded shaft.

[0009] Furthermore, the fixing mechanism also includes a receiving shaft fixedly disposed at the other end of the threaded shaft, and an operating shaft is mounted on the receiving shaft.

[0010] Furthermore, several of the threaded sleeves are distributed circumferentially and at equal intervals on the side wall of the fixed shaft.

[0011] Furthermore, the obstacle avoidance mechanism also includes several multi-stage telescopic rods installed inside the obstacle avoidance support rod, and the U-shaped support head is installed at the end of the obstacle avoidance support rod through several of the multi-stage telescopic rods.

[0012] Compared with the prior art, the present invention provides a fire hose fixing device with an obstacle avoidance support rod. The method of using the device is divided into two independent stages: fixing and obstacle avoidance. When fixing, the limiting angle steels at both ends of the fixing shaft are clamped to the right-angle corner of the wall outside the window to form a triangular support structure. Then, the threaded shaft is rotated to screw in, so that the threaded shaft and the other end of the fixing clamp are clamped to the window frame, completing the installation of the device body. After that, the fire hose is tied to the side wall of the fixing shaft with a rope. When avoiding obstacles, the obstacle avoidance support rod is taken out separately, and the U-shaped support head at the end is used to clamp and push the fire hose to bypass the air conditioner outdoor unit, anti-theft net and other facilities in front of the window, so as to smoothly enter the room. The device has significant advantages: Firstly, the fixing mechanism uses a double locking mechanism of angle steel clamping and threaded clamping to secure the hose to the windowsill, enabling vertical laying of fire hoses and improving fire extinguishing efficiency. Secondly, the obstacle avoidance support rod is retractable and easy to carry, and the U-shaped support head can precisely move the hose, avoiding the influence of external wall obstacles and effectively laying fire hoses vertically, which is especially suitable for complex external wall environments. The overall structure is simple and easy to operate, which not only improves the safety and efficiency of fire extinguishing operations, but also significantly enhances the site adaptability of hose deployment.

[0021] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0022] As attached Figure 1 To be continued Figure 5 As shown:

[0023] Example 1:

[0024] This invention provides a fire hose fixing device with an obstacle avoidance strut, comprising a fixing shaft 1 and an obstacle avoidance strut 4. A fixing clamp 2 is fixedly connected to the fixing shaft 1. The device also includes: a fixing mechanism, disposed on the fixing shaft 1 and the fixing clamp 2, for binding and fixing the fire hose; the fixing mechanism includes several friction strips 10 fixedly disposed on the side wall of the fixing shaft 1; limit angle steels 3 are fixedly disposed at both ends of the fixing shaft 1; a threaded shaft 7 is screwed onto the fixing clamp 2; a rope is bound to the fire hose, and the other end of the rope is bound to the fixing shaft 1; and an obstacle avoidance mechanism, disposed on the obstacle avoidance strut 4, which includes a U-shaped support head 14 fixedly disposed at the end of the obstacle avoidance strut 4.

[0025] Meanwhile, the device is designed with two independent stages for installation and obstacle avoidance. During installation, the limiting angle steels 3 at both ends of the fixing shaft 1 are engaged with the right-angle corner of the wall outside the window, forming a triangular support structure. The anti-slip texture 12 on the inner wall of the limiting angle steel 3 enhances friction with the wall surface. Then, the operating shaft 9 is rotated, driving the threaded shaft 7 to screw into the threaded sleeve 11 via the receiving shaft 8. This causes the clamping block 6 and the support pad 5 at the other end of the fixing clamp 2 to clamp the window frame, completing the installation of the device. Afterward, the fire hose is tied to the side wall of the fixing shaft 1 with a rope. The friction strip 10 increases the rope's adhesion and prevents slippage. During obstacle avoidance, the obstacle avoidance support rod 4 is removed separately. The multi-stage telescopic rod 13 inside is stretched according to the distance to the obstacle. The U-shaped support head 14 at the end engages and pushes the fire hose, allowing it to bypass the air conditioner unit, security grille, and other facilities in front of the window, thus smoothly entering the room. The device has significant advantages: Firstly, the fixing mechanism uses a double locking mechanism of angle steel clamping and threaded clamping to secure the hose to the windowsill, enabling vertical laying of fire hoses and improving fire extinguishing efficiency. Secondly, the obstacle avoidance support rod 4 is retractable and easy to carry, and the U-shaped support head 14 can precisely move the hose, avoiding the influence of external wall obstacles and effectively laying fire hoses vertically, which is especially suitable for complex external wall environments. The overall structure is simple and easy to operate, which not only improves the safety and efficiency of fire extinguishing operations, but also significantly enhances the site adaptability of hose deployment.

[0026] Example 2:

[0027] refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The fixing mechanism includes a fixing shaft 1, a friction strip 10, a limiting angle steel 3, an anti-slip texture 12, a fixing clamp 2, a threaded sleeve 11, and a threaded shaft 7.

[0028] By setting a fixed shaft 1 and fixing limiting angle steels 3 at both ends of the fixed shaft 1, and setting the limiting angle steels 3 to be right angles, the fixed shaft 1 can be supported on the corner of the wall outside the window by the two limiting angle steels 3 during use. The two limiting angle steels 3 can be locked onto the right angle of the outer wall of the corner, so that the fixed shaft 1 can be supported on the lower left or lower right corner of the window by the two limiting angle steels 3, forming a triangular support structure with the corner of the wall outside the window. In addition, several anti-slip textures 12 are set inside the limiting angle steels 3, so that the friction between the inner wall of the limiting angle steels 3 and the corner of the wall can be increased, thereby improving the support stability of the fixed shaft 1. In addition, several friction strips 10 are fixedly connected to the side wall of the fixed shaft 1, so that when the fire hose is tied to the fixed shaft 1 by rope, the friction strips 10 can increase the friction between the rope and the fixed shaft 1, so that the fire hose can be more safely and securely tied to the windowsill by the fixed shaft 1.

[0029] Meanwhile, a fixing clamp 2 is fixedly connected to the fixing shaft 1, and a threaded sleeve 11 is fixedly connected to one end of the fixing clamp 2, so that the fixing clamp 2 can be screwed onto the threaded shaft 7 through the threaded sleeve 11. Thus, when the fixing shaft 1 is installed on the lower left or lower right corner of the window by the limiting angle steel 3, the fixing clamp 2 and the threaded shaft 7 can be fixedly clamped on the window, thereby achieving the purpose of fixing the fixing clamp 2 and the fixing shaft 1 to the lower left or lower right corner of the window for use.

[0030] Secondly, a receiving shaft 8 is fixedly connected to one end of the threaded shaft 7, and an operating shaft 9 is installed on the receiving shaft 8. This allows the threaded shaft 7 to be easily rotated and adjusted for clamping by the receiving shaft 8 in conjunction with the operating shaft 9 when it is being clamped. A clamping block 6 is fixedly connected to the other end of the threaded shaft 7, and a support pad 5 is fixedly connected to the other end of the fixed clamp 2. This allows the threaded shaft 7 to be clamped onto the window by the support pad 5 and the clamping block 6, thereby improving the stability of the fixed clamp 2 during clamping.

[0031] Example 3:

[0032] refer to Figure 1 and Figure 5 The obstacle avoidance mechanism includes an obstacle avoidance strut 4, a multi-stage telescopic strut 13, and a U-shaped support head 14;

[0033] By providing an obstacle avoidance strut 4, and by setting the obstacle avoidance strut 4, the fixed shaft 1, and the fixed clamp 2 as separate components, the fixed shaft 1 and the fixed clamp 2 can be used independently, and the obstacle avoidance strut 4 can also be used independently. When firefighters encounter other facilities blocking the fire hose in front of the window during fire fighting in the building, they can take out the obstacle avoidance strut 4 and push the fire hose by using the U-shaped support head 14 installed at the end of the obstacle avoidance strut 4, so that the fire hose can bypass the other facilities in front of the window. This makes it easier for the fire hose to be fixed and tied to the window of the building by the fixed shaft 1 and the fixed clamp 2 for use.

[0034] Meanwhile, a multi-stage telescopic rod 13 is installed inside the obstacle avoidance support rod 4, so that the multi-stage telescopic rod 13 can retract into the interior of the obstacle avoidance support rod 4, thereby reducing the volume of the obstacle avoidance support rod 4 and making it easier for the obstacle avoidance support rod 4 to be carried and used by firefighters. The U-shaped support head 14 is installed at the end of the obstacle avoidance support rod 4 through the multi-stage telescopic rod 13, so that the U-shaped support head 14 can also be extended with the multi-stage telescopic rod 13 when in use, so that the U-shaped support head 14 has a longer working distance. This makes it easier to adjust the working length of the multi-stage telescopic rod 13 to push the fire hose for obstacle avoidance when there are facilities of different lengths in front of the window, thereby improving the ease of use of the obstacle avoidance support rod 4.

[0035] In addition, the U-shaped support head 14 can easily lock and limit the fire hose, improving the ease of moving the fire hose.

[0036] Working principle: First, a fixed installation is performed: After the operator carries the device to the window location on the fire floor of the high-rise building, the limiting angle steels 3 at both ends of the fixing shaft 1 are respectively engaged with the lower left or lower right corner of the wall outside the window opening. Since the limiting angle steel 3 is right-angled, its inner wall can naturally conform to the right-angle edge of the outer wall, forming a stable triangular support point. At the same time, the anti-slip texture 12 densely distributed on the inner wall of the limiting angle steel 3 embeds into the micro-pits on the wall surface under the action of gravity and compression, significantly improving the anti-slip ability and preventing the fixing shaft 1 from being displaced due to the pulling of the water hose; then, the operator... The operator holds the operating shaft 9 installed on the receiving shaft 8 and rotates it clockwise, causing the receiving shaft 8 to drive the threaded shaft 7 to screw into the threaded sleeve 11 fixed at one end of the fixed clamp 2. The clamping block 6 at the end of the threaded shaft 7 then moves towards the support pad 5 at the other end of the fixed clamp 2 until the clamping block 6 and the support pad 5 are tightly pressed against the inner and outer walls of the window frame. The fixed clamp 2 and the window frame are rigidly clamped by the screwing locking force. At this time, the fixed shaft 1 is firmly positioned at the corner of the window. The entire installation process can be completed without additional tools. Next, the fire hose is secured: the operator pulls the fire hose from the outdoor side to the side of the fixed shaft 1, takes the pre-equipped high-strength rope, tightly wraps one end of the rope around the outer wall of the fire hose and ties it in a knot, and wraps the other end of the rope around the side wall of the fixed shaft 1 multiple times. The multiple friction strips 10 evenly distributed along the axial direction on the surface of the fixed shaft 1 play a key role in this process. The raised edges of the friction strips 10 significantly increase the static friction coefficient between the rope and the metal surface of the fixed shaft 1. Even if the fire hose is filled with high-pressure water and produces violent pulsations, the rope will not slip or loosen along the axial direction. At the same time, the limiting angle steel 3 fixed at both ends of the fixed shaft 1 also forms a physical limit on the rope binding area, further preventing the rope from coming out, thereby ensuring that the fire hose is reliably suspended and fixed to the outside of the windowsill. This is used for the vertical laying of the fire hose, improves the fire extinguishing efficiency, effectively suppresses the large swing of the fire hose caused by strong winds at high altitudes or the recoil of the water gun, and reduces the physical burden on firefighters when operating the gun. Finally, obstacle avoidance is performed: When there are obstacles such as air conditioner outdoor units, security grilles, or protruding decorative components in front of the window, the operator does not need to readjust the fixed shaft 1. Instead, they take out the separately carried obstacle avoidance support rod 4 and, based on the actual distance of the obstacle protruding from the wall, pull out the multi-stage telescopic rod 13 stored inside the obstacle avoidance support rod 4 step by step to the appropriate length. Then, the U-shaped support head 14 at the end of the obstacle avoidance support rod 4 is inserted from the outside of the hose, so that the hose is embedded in the arc-shaped groove of the U-shaped support head 14. By pushing and pulling the handle end of the obstacle avoidance support rod 4, the U-shaped support head 14 is used to apply lateral thrust to the hose, guiding the hose around the outside or above the obstacle. After the hose has passed the obstacle and smoothly entered the room, the multi-stage telescopic rod 13 can be retracted to reduce its size, making it easier for firefighters to carry and continue to carry out subsequent firefighting tasks. The whole process does not require disassembling the fixed shaft 1, nor does it require bending the hose to affect the flow of water, which greatly improves the efficiency and safety of hose deployment in complex high-rise exterior wall environments.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
