Description
Technical Field
[0001] The utility model relates to the technical field of fire hydrants, in particular to fire hydrant equipment. Background Art
[0002] The main function of a fire hydrant is to control combustibles, isolate combustibles, and eliminate fire sources. In winter, the outdoor temperature is very low, especially in the north, and the water in the fire hydrant is almost static. The low temperature makes the water in the fire hydrant easy to freeze. The freezing of the water in the fire hydrant will cause two results. First, when it is urgently needed to extinguish the fire, the fire hydrant cannot be opened due to freezing, which directly causes the fire hydrant to be unusable; second, the water will expand when it turns into ice, which can easily cause the fire hydrant to rupture. At the same time, fire hydrants set on the ground are easy to be hit, and there will be safety hazards after the fire hydrants are hit, so improvements are made to their defects.

[0018] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.
[0019] Reference Figures 1 to 4 The utility model embodiment provides a fire hydrant device, which includes a bracket 1: a bottom plate 2 is fixedly connected to the bottom of the bracket 1, and an electric telescopic rod 3 is fixedly connected to the two side walls of the bracket 1, the output shaft of the electric telescopic rod 3 passes through the bracket 1, and is fixedly connected to a sealing shell 4, a fire hydrant body 5 is arranged in a pair of sealing shells 4, and a heating bin 6 is fixedly connected to the two side walls of the pair of sealing shells 4, a heating wire 7 is fixedly connected to the inner wall of the heating bin 6, and a blower fan 8 is fixedly connected to the inner wall of the heating bin 6, an air inlet 9 is opened on the side walls of the pair of sealing shells 4, a plurality of ventilation holes 10 are opened on the side walls of the heating bin 6, and a protective mechanism is arranged in the pair of sealing shells 4. Through the arrangement of the bracket 1, the electric telescopic rod 3, the sealing shell 4, the heating wire 7 and the blower fan 8, the fire hydrant body 5 can be heated in winter, thereby preventing the water source in the fire hydrant body 5 from freezing.
[0020] The force is evenly distributed, which improves the stability of the bracket 1 in use. The pair of bottom plates 2 are symmetrically arranged about the central axis of the bracket 1.
[0021] To facilitate installation and disassembly of the bracket 1 , a pair of bolts 11 penetrate each of the pair of bottom plates 2 .
[0022] The symmetrical arrangement allows for better sealing of the fire hydrant body 5 , and a pair of sealing shells 4 are symmetrically arranged about the central axis of the fire hydrant body 5 .
[0023] When the fire hydrant body 5 is impacted by external force, the impact force can be buffered, thereby protecting the fire hydrant body 5. The protective mechanism includes a pair of protective plates 12, and the pair of protective plates 12 are respectively fixedly connected to the bottom inner walls of a pair of sealing shells 4, and the side walls of the pair of protective plates 12 are provided with air guide ports 13. A plurality of limiting bins 14 are fixedly connected to the side walls of the pair of sealing shells 4, and a positioning block 15 is provided in the limiting bin 14. A spring 16 is fixedly connected between the positioning block 15 and the inner wall of the limiting bin 14, and a connecting block 17 is fixedly connected to the other side of the positioning block 15. The other side of the connecting block 17 passes through the side wall of the limiting bin 14 and is fixedly connected to the side wall of the protective plate 12.
[0024] In order to buffer impact forces in different directions, a plurality of limit bins 14 are distributed in a ring shape about the central axis of a pair of protection plates 12 .
[0025] In order to facilitate the discharge of excess gas inside and avoid excessive pressure in the sealed shell 4, an air outlet pipe 18 is fixedly connected to the side wall of one of the sealed shells 4.
[0026] Working principle: When the utility model is used, the fire hydrant body 5 is installed to the working position, and the base plate 2 and the bracket 1 are installed to one side by the bolts 11. When used in winter, the heating wire 7 is connected to the power supply, and the blower fan 8 is started. The blower fan 8 blows air to the heating wire 7, thereby blowing the heating wire 7 to the fire hydrant body 5 through the air inlet 9 and the air guide port 13 to heat the fire hydrant body 5, increase the surface temperature of the fire hydrant body 5, and avoid the freezing of the water source inside the fire hydrant body 5. When the fire hydrant body 5 is impacted, the impact force impacts the side wall of the sealing shell 4, and then squeezes the limit bin 14. The limit bin 14 compresses the spring 16, thereby protecting the fire hydrant body 5 through the elastic reset effect of the spring 16 and the protective plate 12 to buffer the impact force. When the fire hydrant body 5 is needed, the electric telescopic rod 3 is started, and a pair of electric telescopic rods 3 drive the sealing shell 4 and the protective plate 12 to move away from each other, so as to facilitate firefighters to use the fire hydrant body 5.

Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
