Description

Technical Field

[0001] This utility model relates to the field of fire-fighting equipment technology, and in particular to a fire hose reel for fire fighting. Background Technology

[0002] In the field of fire-fighting equipment technology, fire hose reels are indispensable equipment in fire-fighting operations, mainly used for the storage and release of fire hoses. However, existing fire hose reels have significant shortcomings in use. The power transmission control is rigid; once the reel drive is started, power is continuously transmitted and cannot be quickly interrupted as needed, easily leading to motor idling and energy consumption. Furthermore, the reel is prone to accidental rotation, interfering with operations and posing safety hazards. There is a lack of effective hose squeezing structures, making it difficult to remove residual water from the hoses after use. Long-term dampness accelerates aging and shortens service life. Additionally, unsqueezed hoses are loosely stored, occupy a large amount of space, and are prone to tangling and knotting during release, affecting emergency use efficiency and failing to meet the high-efficiency and safe requirements of fire-fighting operations.

[0003] Patent publication number "CN222788374U" discloses a utility model relating to the field of fire safety technology, specifically a fire hose reel, comprising: a main body including a base, on which a take-up reel is rotatably connected; and a limiting mechanism including a fixing plate fixedly connected to the top of the take-up reel, a guide tube fixedly connected to the surface of the fixing plate, a spring fixedly connected to the surface of the guide tube, a movable rod fixedly connected to the surface of the spring, the movable rod sliding on the surface of the guide tube, and a limiting rope fixedly connected to the surface of the movable rod. This utility model, through the fixing plate, guide tube, spring, movable rod, and limiting rope, achieves the limiting of the fire hose, ensuring that during the winding process, the limiting rope restricts the folds in the fire hose, smoothing and eliminating them, effectively increasing the usable space of the take-up reel and reducing the damage rate of the fire hose on the take-up reel.

[0004] In response to the aforementioned issues, existing fire hose reels lack a flexible power interruption structure. Once the power connection is established, it is difficult to disconnect, and the motor is prone to idling, resulting in energy waste. Idling may also cause accidental rotation, interfering with operations and posing safety hazards. Furthermore, the lack of a water-squeezing component means that residual moisture in the hose cannot be discharged. The residual moisture inside the hose can easily cause it to loosen during storage and become tangled and knotted during release, affecting its use and making it difficult to meet the requirements for efficient operation. Utility Model Content

[0005] The purpose of this utility model is to provide a fire hose reel for fire fighting, which solves the problem of inflexible control of equipment power transmission and the problem of previous equipment being unable to handle residual moisture in the hose.

[0006] To achieve the above objectives, this utility model provides a fire hose reel for fire fighting, including a base frame;

[0007] It also includes slide rails fixedly connected to the inside of the base frame;

[0008] A push plate is slidably connected to the top inner side of the slide rail, and an electric push rod is fixedly connected to the outer side of the bottom frame. The output end of the electric push rod passes through the bottom frame and is fixedly connected to the side of the push plate. A main motor is fixedly connected to the side of the push plate, and a hexagonal locking block is fixedly connected to the output end of the main motor. A rear support plate is fixedly connected to the bottom top side of the bottom frame, and a connecting rod is rotatably connected inside the rear support plate. A hexagonal slot is opened on the side of the connecting rod, and the hexagonal locking block can be slidably locked into the inner side of the hexagonal slot.

[0009] The bottom frame is fixedly connected to a front support plate at its top, the other end of the connecting rod is rotatably connected to the inside of the front support plate, and a support block is fixedly connected to the side of the rear support plate.

[0010] The front and rear support plates are equipped with water-squeezing components on their inner sides. Each water-squeezing component includes a chute, which is located on the inner side of the rear support plate. A convex slider is slidably connected to the inner side of the chute. A hydraulic rod is fixedly connected to the top side of the convex slider. The other end of the hydraulic rod is fixedly connected to the inner side of the chute. A spring is fixedly connected between the inner side of the chute and the convex slider, and the spring is sleeved on the outer side of the hydraulic rod.

[0011] The front support plate and the rear support plate are rotatably connected by a lower squeezing roller. A secondary motor is fixedly connected to the outer side of the front support plate. The output end of the secondary motor passes through the front support plate and is fixedly connected to the lower squeezing roller. An upper squeezing roller is rotatably connected between the two convex sliders.

[0012] A reel is fixedly connected to the outer side of the connecting rod.

[0013] The bottom side of the base frame is rotatably connected to casters, and the side of the base frame is fixedly connected to a handle.

[0014] This utility model discloses a fire hose reel for firefighting. An electric actuator pushes a push plate along a slide rail, allowing the hexagonal locking block at the main motor output end to precisely engage or disengage with the hexagonal locking slot of the connecting rod. The power transmission state can be switched at any time according to actual operational needs. A stable power connection is maintained when hose reeling is required, ensuring the reel operates according to operating instructions. When power is not needed, the transmission is interrupted promptly to prevent accidental rotation of the reel from interfering with operations or causing energy waste, thus ensuring the controllability and operational safety of hose reeling. A hydraulic rod in the water-squeezing assembly pushes a convex slider to move within a groove, causing the upper and lower water-squeezing rollers to cooperate, effectively squeezing the hose during reeling. This squeezes out residual water from the hose during storage, preventing long-term water retention that could lead to aging and damage. Simultaneously, the squeezed hose is more compact, further reducing space occupation when wound on the reel. The squeezed hose also maintains a neat state during release, facilitating quick and easy deployment, meeting the needs of firefighting operations for hose maintenance and efficient use.

[0022] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0023] Please see Figures 1-5 .

[0024] A fire hose reel for firefighting includes a base frame 1;

[0025] It also includes a slide rail 8 fixedly connected to the inner side of the base frame 1;

[0026] A push plate 11 is slidably connected to the top inner side of the slide rail 8. An electric push rod 10 is fixedly connected to the outer side of the bottom frame 1. The output end of the electric push rod 10 passes through the bottom frame 1 and is fixedly connected to the side of the push plate 11. A main motor 9 is fixedly connected to the side of the push plate 11. A hexagonal locking block 12 is fixedly connected to the output end of the main motor 9. A rear support plate 2 is fixedly connected to the bottom top side of the bottom frame 1. A connecting rod 18 is rotatably connected inside the rear support plate 2. A hexagonal locking slot 15 is opened on the side of the connecting rod 18. The hexagonal locking block 12 can be slidably locked into the inner side of the hexagonal locking slot 15.

[0027] Firstly, the slide rail 8, through its fixed connection with the base frame 1, forms a stable guiding structure. Its inner side's sliding connection with the push plate 11 effectively restricts the movement trajectory of the push plate 11, ensuring that the push plate 11, driven by the electric actuator 10, can only reciprocate linearly along the length of the slide rail 8, avoiding lateral deviation or jamming. The electric actuator 10, as a power actuator, has its cylinder fixed to the base frame 1, and its piston rod connected to the push plate 11. When the electric actuator 10 receives a control signal, the piston rod extends or retracts, thereby driving the push plate 11, the main motor 9 mounted on the push plate 11, and the hexagonal locking block 12 to move synchronously. The main motor 9 is fixed to the hexagonal locking block 12 via its output shaft. When the hexagonal locking block 12 is precisely engaged into the hexagonal slot 15 on the side of the connecting rod 18 by the push of the electric actuator 10, the two form a rigid connection. The torque generated by the main motor 9 after starting will be directly transmitted to the connecting rod 18 through the cooperation of the output shaft, the hexagonal locking block 12 and the hexagonal slot 15, thereby driving the connecting rod 18 to rotate around its own axis. When it is necessary to stop the power transmission, the electric actuator 10 drives the push plate 11 to move in the opposite direction, causing the hexagonal locking block 12 to disengage from the hexagonal slot 15. At this time, the rotation of the main motor 9 cannot affect the connecting rod 18, realizing flexible control of the rotation state of the connecting rod 18. The power connection and disconnection states can be switched at any time according to actual needs.

[0028] Furthermore, a front support plate 5 is fixedly connected to the top of the bottom frame 1, and the other end of the connecting rod 18 is rotatably connected to the inner side of the front support plate 5. A support block 16 is fixedly connected to the side of the rear support plate 2. The front support plate 5 and the rear support plate 2 respectively support both ends of the connecting rod 18, ensuring the stability of the connecting rod 18 during rotation and preventing swaying or displacement. The support block 16 is fixedly connected to the rear support plate 2, which can enhance the structural strength of the rear support plate 2, improve its support capacity for the connecting rod 18, and ensure the stability of the overall structure.

[0029] Furthermore, both the front support plate 5 and the rear support plate 2 are provided with a water squeezing assembly 7 on their inner sides. The water squeezing assembly 7 includes a slide groove 71, which is opened on the inner side of the rear support plate 2. A convex slider 74 is slidably connected to the inner side of the slide groove 71. A hydraulic rod 72 is fixedly connected to the top side of the convex slider 74. The other end of the hydraulic rod 72 is fixedly connected to the inner side of the slide groove 71. A spring 73 is fixedly connected between the inner side of the slide groove 71 and the convex slider 74. The spring 73 is sleeved on the outer side of the hydraulic rod 72. The fixed connection between the front support plate 5 and the bottom frame 1 forms a symmetrical support structure with the rear support plate 2. The two ends of the connecting rod 18 are rotatably connected to the inner sides of the front support plate 5 and the rear support plate 2, respectively. This two-end support method evenly distributes the radial force on the connecting rod 18 to the two support plates, greatly reducing the risk of deformation caused by uneven force during rotation. This ensures the smoothness and coaxiality of the connecting rod 18's rotation, avoiding problems such as swaying and tilting that affect overall operation. The support block 16, fixedly connected to the rear support plate 2, has its bottom in contact with the bottom frame 1 or other stable structures, forming a triangular support structure. Utilizing the stability principle of a triangle, this effectively enhances the deformation resistance of the rear support plate 2. Especially when the connecting rod 18 transmits large torques or bears the weight of the reel 6 and hose, the support block 16 provides additional support force to the rear support plate 2, preventing it from bending or breaking due to excessive force, thus ensuring the structural strength and service life of the entire support system.

[0030] Furthermore, a lower squeezing roller 14 is rotatably connected between the front support plate 5 and the rear support plate 2. A secondary motor 4 is fixedly connected to the outer side of the front support plate 5. The output end of the secondary motor 4 passes through the front support plate 5 and is fixedly connected to the lower squeezing roller 14. An upper squeezing roller 13 is rotatably connected between the two convex sliders 74. A groove 71 is formed on the inner side of the front support plate 5 and the rear support plate 2. Its shape matches the convex slider 74. The protruding part of the convex slider 74 is embedded in the groove 71. This structural design not only provides precise sliding guidance for the convex slider 74, but also prevents the convex slider 74 from falling out of the groove 71, ensuring that it can only move up and down along the length direction of the groove 71. The hydraulic rod 72 is fixed at both ends to the inner side of the slide groove 71 and the convex slider 74, respectively. As the main driving element, it achieves extension and retraction through the pressure change of hydraulic oil. When the hydraulic rod 72 extends, it pushes the convex slider 74 to move downward along the slide groove 71; when the hydraulic rod 72 shortens, it pulls the convex slider 74 to move upward. The spring 73 is sleeved on the outside of the hydraulic rod 72, with one end fixed to the inner side of the slide groove 71 and the other end connected to the convex slider 74. When the hydraulic rod 72 moves, the spring 73 is compressed or stretched along with the movement of the convex slider 74, generating elastic potential energy. This elastic potential energy can, on the one hand, buffer the impact force when the hydraulic rod 72 moves, making the movement of the convex slider 74 more stable and avoiding violent vibration; on the other hand, when the hydraulic rod 72 loses power, the restoring force of the spring 73 can drive the convex slider 74 back to the initial position, playing an auxiliary restoring role.

[0031] Furthermore, a reel 6 is fixedly connected to the outer side of the connecting rod 18. When the connecting rod 18 rotates, it drives the reel 6 to rotate synchronously. The reel 6 is used to wind the fire hose. The forward and reverse rotation of the connecting rod 18 realizes the storage and release of the fire hose, meeting the needs of fire hose use and management in firefighting operations.

[0032] Furthermore, casters 3 are rotatably connected to the bottom side of the base frame 1, and handles 17 are fixedly connected to the side of the base frame 1. The casters 3 allow the base frame 1 to move flexibly, facilitating the transfer of the device between different locations. The handles 17 provide a gripping point for the operator, and together with the casters 3, the device can be easily pushed, improving its ease of movement and facilitating rapid deployment at fire scenes.

[0033] The complete working process is as follows: First, the operator holds the handle 17 on the side of the base frame 1 and pushes the device to the designated position using the bottom casters 3. The casters 3 can steer flexibly, making it easy to navigate obstacles. When storing or releasing the hose, the electric actuator 10 is activated, pushing the push plate 11 to slide along the slide rail 8, causing the hexagonal locking block 12 of the main motor 9 to engage with the hexagonal locking slot 15 of the connecting rod 18. The main motor 9 operates, driving the connecting rod 18 to rotate through the locking block, which in turn causes the outer reel 6 to rotate synchronously. Rotation in the forward direction realizes the hose winding and storage, while rotation in the reverse direction releases the hose. During storage, the secondary motor 4... The lower squeezing roller 14 is driven to rotate, and at the same time, the hydraulic rod 72 of the squeezing assembly 7 pushes the convex slider 74 to move down along the slide groove 71, so that the upper squeezing roller 13 and the lower squeezing roller 14 clamp the water belt. The spring 73 in the slide groove 71 elastically deforms with the thickness of the water belt to buffer the pressure and prevent damage. Under the combined squeezing and rotation of the rollers, the residual water in the water belt is squeezed out. During operation, the front support plate 5 and the rear support plate 2 support connecting rod 18 to ensure smooth rotation. The support block 16 on the side of the rear support plate 2 enhances its structural strength. After completion, the electric push rod 10 drives the locking block to disengage from the locking slot, interrupting the power transmission and the device returns to standby.

[0034] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
