Description

Technical Field

[0001] This utility model belongs to the field of fire hydrant boxes, and in particular relates to a fire hydrant box that can automatically retract the fire hose. Background Technology

[0002] A fire hydrant box is a box used to store fire hydrants. It is used to extinguish fires when they start. It needs to be equipped with fire hoses, fire nozzles, etc. The installation methods include surface mounting, concealed mounting, and semi-concealed mounting.

[0003] A fire hydrant box (publication number: CN215084525U) disclosed in this invention includes: a box body; a fire hydrant disposed within the box body and connected to a water inlet pipe; and a rotating shaft disposed at the connection point between the fire hydrant and the water inlet pipe, the rotating shaft being used to rotate the fire hydrant. Common fire hydrant boxes often need to be very large and thick. The fire hydrant box provided in this embodiment includes a box body, a fire hydrant, and a rotating shaft. In this embodiment, a rotating shaft is also provided at the connection point between the fire hydrant and the water inlet pipe. The rotating shaft is used to rotate the fire hydrant. In standby mode, the rotating shaft rotates the fire hydrant outlet towards one side of the fire hydrant box. Compared to conventional fire hydrant outlets facing outwards, the fire hydrant box can be made thinner. Combined with a steel coil-free design, the fire hydrant box can be made more compact and thinner, effectively improving the harmony of the building's interior design.

[0004] In the aforementioned application, the interaction between the rotating shaft and the fire hydrant assembly makes it difficult to retract and place the hose when it is needed, ultimately requiring manual winding, which is very inconvenient. Therefore, we propose a fire hydrant box that can automatically wind up the hose. Utility Model Content

[0005] The purpose of this invention is to provide a fire hydrant box that can automatically rewind fire hoses. Through the cooperation of the rotating shaft and the pulley, the problem of automatic rewinding and cleaning / maintenance of fire hoses in existing systems is solved.

[0027] Please see Figures 1-4 The present invention is a fire hydrant box with automatic hose reel, comprising a box body 1, a reel door 2 slidably connected to the side of the box body 1, a cabinet door 3 fixed to the side of the box body 1, a bracket 6 fixedly connected to the inner side of the box body 1, and an automatic hose reel device 8 provided in the box body 1.

[0028] The automatic hose reel device 8 includes a motor support plate 81, which is fixedly connected to the inner side of the housing 1.

[0033] As shown in the figure, the driving bevel gear 85 and the driven bevel gear 97 mesh with each other, and the fire extinguisher holder 12 is fixedly connected to the inner bottom wall of the housing 1. The meshing of the driving bevel gear 85 and the driven bevel gear 97 realizes the linkage between the automatic hose reel device 8 and the hose cleaning and flattening device 9, without the need for an additional power source. The fire extinguisher holder 12 provides a fixed position for the fire extinguisher.

[0034] As shown in the figure, a brush is attached to the inner top wall of the cleaning and flattening block 94. Two fire extinguisher holders 12 are provided, symmetrically arranged along the vertical central axis of the housing 1. The brush on the inner top wall of the cleaning and flattening block 94 effectively removes impurities from the surface of the fire hose, ensuring its cleanliness. The two symmetrically distributed fire extinguisher holders 12 can hold two fire extinguishers, meeting more emergency needs.

[0035] A specific application of this embodiment is as follows: In this automatic hose reel device 8, the motor 82 serves as the core power source. It is securely connected to the inner side of the housing 1 via a motor support plate 81. The motor support plate 81 ensures sufficient support and stability to withstand the vibration and torque generated when the motor 82 is running. When the motor 82 is powered on, it drives the output shaft to rotate. This output shaft and the rotating shaft 83 are rigidly connected by a key, thereby efficiently transmitting the rotational power of the motor 82 to the rotating shaft 83, causing the rotating shaft 83 to rotate synchronously. After receiving power from the motor 82, the rotating shaft 83 achieves the branching transmission of power. On one hand, there is a pulley 84 on the circumference of the rotating shaft 83. The pulley 84 and the pulley 88 on the rotating shaft 87 are connected by a belt 86. Based on the belt drive principle, when the rotating shaft 83 drives the first pulley 84 to rotate, the belt 86 moves under the action of friction, thereby driving the second pulley 88 to rotate, causing the rotating shaft 87 to rotate synchronously. One end of the rotating shaft 87 is rotatably connected to the rotating disk 7 through a bearing, ensuring that the rotating disk 7 can rotate flexibly around the rotating shaft 87. A hose clamping strip 10 is provided on the inner circumference of the rotating disk 7. The hose clamping strip 10 and the rotating disk 7 are fitted with a dovetail groove, allowing the hose clamping strip 10 to slide along the radial direction of the rotating disk 7. When winding the hose, the end of the hose is placed between the hose clamping strip 10 and the rotating disk 7, and the hose end is firmly clamped by clamping. When the rotating shaft 87 rotates under the drive of the second pulley 88, the rotating disk 7 rotates synchronously. At this time, under the action of the rotational force of the rotating disk 7, the clamped hose end begins to wind around the rotating shaft 87. As the rotating disc 7 continues to rotate, the hose is gradually and evenly wound onto the rotating shaft 87, completing the hose winding action. The structural design of the bracket 6 can effectively withstand the radial and axial forces on the rotating shaft 87 during hose winding, ensuring the stability of the rotating shaft 87 during operation and preventing component displacement or damage due to factors such as hose tension. This ensures that the automatic hose winding device 8 can operate continuously, stably, and efficiently.

[0036] On the other hand, a driving bevel gear 85 is fixed at one end of the rotating shaft 83. The driving bevel gear 85 meshes with the driven bevel gear 97 in the hose cleaning and flattening device 9. The meshing transmission of bevel gears enables the transmission of power in different directions, thus realizing the power linkage between the automatic hose reeling device 8 and the hose cleaning and flattening device 9. When the driving bevel gear 85 rotates with the rotating shaft 83, it drives the driven bevel gear 97 to rotate through the interaction between the gear teeth, thereby driving the hose cleaning and flattening device 9 to work. At this time, the screw 92 fixedly connected to the driven bevel gear 97 rotates synchronously. The screw support plate 91 and the threaded base 96 together provide stable support for the screw 92. The circumferential surface of the screw 92 is threadedly connected to a threaded sleeve 93. When the screw 92 rotates under the drive of the driven bevel gear 97, the threaded sleeve 93 performs linear reciprocating motion along the axial direction of the screw 92 under the action of threaded transmission. The cleaning and flattening block 94 fixedly connected to the side of the threaded sleeve 93 moves synchronously with the threaded sleeve 93, and the rotating wheel 95 rotatably connected to its side contacts the hose surface. During the hose reel winding process, the roller 95 applies pressure to the hose through rolling contact, smoothing out the wrinkles on the hose surface and preventing irregular winding due to folding and twisting. Simultaneously, the brush attached to the inner top wall of the cleaning and flattening block 94 contacts the hose surface. As the cleaning and flattening block 94 moves, the brush cleans the mud, sand, and impurities adhering to the hose surface, achieving synchronous cleaning of the hose. The limiting plate 98 forms a limiting structure for the cleaning and flattening block 94. When the threaded sleeve 93 moves the cleaning and flattening block 94, the limiting plate 98 restricts the movement trajectory of the cleaning and flattening block 94, preventing it from rotating synchronously with the screw 92, ensuring that the cleaning and flattening block 94 moves stably only in a straight line, and guaranteeing the uniformity of the cleaning and flattening actions.
