[0003] An outdoor fire hydrant is a water supply facility installed on the fire water supply network outside a building. It is mainly used for fire trucks to draw water from the municipal water supply network or the outdoor fire water supply network to implement fire extinguishing. It can also be directly connected to a water hose or a water gun to discharge water for fire extinguishing.

[0004] Fire hydrants are set up outdoors. When it is cold, the fire hydrants will freeze, which will affect fire rescue, so the fire hydrants need to be insulated. The existing insulation measures are to cover the fire hydrants with insulation blankets and bundle and fix the insulation blankets. The fire hydrants are isolated from the low-temperature outside world by the insulation blankets, thereby achieving insulation effect. However, the actual problem is that the insulation effect is poor when the number of bundled insulation blankets is small. Bundling multiple layers of insulation blankets will cause inconvenience in disassembly during use, which will delay fire rescue in case of fire emergencies. In addition, if the water outlet is retained when the fire hydrant is wrapped with the insulation blanket, complete insulation protection cannot be achieved, and the water outlet of the fire hydrant will also freeze, affecting its use. Therefore, there is an urgent need for an antifreeze outdoor fire hydrant. Utility Model Content

[0032] This embodiment provides an outdoor fire hydrant, see Figure 1-Figure 6 As shown, the fire hydrant body 1 is arranged in the insulation chamber 2, and the insulation chamber 2 includes a support frame 21, which is arranged on the ground. The support frame 21 is composed of a top plate 22, a back plate 23 and a bottom plate 24. The top plate 22 is connected to the bottom plate 24 through the back plate 23, and movable plate assemblies 3 are installed on both sides of the support frame 21. A fixed frame 25 is arranged on the front end surface of the support frame 21, and a transparent plate is installed in the fixed frame 25. A heating plate 241 is arranged on the upper end surface of the bottom plate 24, and a temperature sensor 231 is installed on the inner side surface of the back plate 23. The temperature sensor 231 is electrically connected to the heating plate 241, and the heating plate 241 and the temperature sensor 231 are respectively connected to the energy storage battery.

[0033] In the above embodiment, the fire hydrant body 1 is arranged in the insulation chamber 2, the support frame 21 is arranged on the ground, and the support frame 21 is composed of a top plate 22, a back plate 23 and a bottom plate 24. A heating plate 241 is arranged on the upper end surface of the bottom plate 24, that is, a heating plate 241 is arranged in the insulation chamber 2 for heating the fire hydrant body 1, and a temperature sensor 231 is installed on the inner side of the back plate 23. The temperature sensor 231 is electrically connected to the heating plate 241. When the temperature sensor 231 detects that the temperature in the insulation chamber 2 is lower than 10 degrees Celsius, the temperature sensor 231 sends an electrical signal to the heating plate 241, and the heating plate 241 starts to operate. For example, when the temperature in the insulation chamber 2 reaches above 10 degrees Celsius, the temperature sensor 231 controls the heating plate 241 to stop working. Preferably, the temperature sensor 231 is connected to the heating plate 241 through a single-chip microcomputer controller, and the temperature signal emitted by the temperature sensor 231 controls the opening and closing of the heating plate 241 through the single-chip microcomputer, so as to ensure that the fire hydrant body 2 is at a non-freezing temperature in the insulation chamber 2, thereby preventing the water in the fire hydrant body 1 from condensing and affecting the normal use of the fire hydrant body 1. By setting a specific temperature point to control the opening and closing of the heating plate 241, the electric energy consumed by the operation of the heating plate 241 in the energy storage battery can be reduced, thereby increasing the service life of the energy storage battery, which is beneficial to increasing the insulation time in the insulation chamber 2, and can also avoid damage to the fire hydrant components caused by excessive heating temperature. The use of energy storage batteries for power supply can improve the independence of the operation of the device. Compared with the use of external power supplies such as AC power, it can also operate independently without being affected in the event of a power outage. The fire hydrant body 1 is arranged in the insulation chamber 2 to prevent the cold air convection in a low temperature environment from causing the heat of the fire hydrant body 1 to dissipate too quickly, which is beneficial to maintaining the temperature of the fire hydrant body 1 and preventing the fire hydrant from freezing. The insulation chamber 2 cover is arranged on the outside of the fire hydrant body 1 to prevent rain erosion and extend the service life of the fire hydrant. A transparent plate is installed on the front end of the support frame 21. The patrol personnel can directly observe the status of the fire hydrant through the transparent plate. If any abnormality is found, maintenance can be carried out in time, which is beneficial to improving the safety and stability of the fire hydrant body 1.

[0034] The single-chip microcomputer mentioned above is a microcomputer control device that integrates processor core, memory, input and output interface, timer and other functions on a single chip. It is usually composed of a central processing unit (CPU), memory (ROM, RAM), input and output ports (I / O), timer / counter and serial communication interface, etc., and can complete the control tasks of specific electrical components.

[0035] In one embodiment of the present application, see Figure 3As shown, the movable plate assembly 3 includes a slide groove cavity 31, and the slide groove cavity 31 is arranged at the bottom of the support frame 21. The inner walls on both sides of the slide groove cavity 31 are provided with slide rails 32. A slide plate 33 is nested in the slide groove cavity 31. The slide plate 33 is movably connected to the slide rail 32. A spring 34 is arranged between the bottom of the slide plate 33 and the bottom of the slide groove cavity 31, and a handle 331 is installed on the outer side of the slide plate 33.

[0036] In the above embodiment, the slide groove cavity 31 is buried under the ground, and the slide plate 33 is slidably connected to the slide groove cavity 31 through the slide rail 32. A spring 34 is arranged between the bottom of the slide plate 33 and the bottom of the slide groove cavity 31. The spring 34 supports the slide plate 33 in a closed state on both sides of the support frame 21 in the initial state. When the fire hydrant body 1 needs to be used, a handle 331 is installed on the outer side of the slide plate 33. The slide plate 33 is pressed down by the handle 331, and the slide plate 33 slides into the slide groove cavity 31. The spring 34 is elastically deformed under pressure, such as Figure 4 As shown, after the slide plate 33 is lowered, the fire hose 100 can be connected to the fire hydrant body 1. After use, the fire hose 100 is removed, and the spring 34 resets and pushes the slide plate 33 to move up and reset automatically, so that the side of the support frame 21 is closed. Compared with the flip-opening and closing movable plate, the opening space required for the slide plate 33 and the slide groove cavity 31 is smaller, which is beneficial to improving the flexibility of the opening and closing of the movable plate.

[0037] In one embodiment of the present application, refer to Figure 5 As shown, a photovoltaic panel 4 is installed on the back plate 23 of the support frame 21 , and the photovoltaic panel 4 is connected to the back plate 23 via a connecting block 41 , and the photovoltaic panel 4 is connected to an energy storage battery.

[0038] In the above embodiment, when sunlight shines on the semiconductor material in the photovoltaic panel 4, photons will excite the electrons in the semiconductor material, so that the electrons gain energy and begin to flow to generate current. Preferably, the photovoltaic panel 4 is connected to the energy storage battery through components such as a current stabilizer. The current stabilizer can convert the current generated by the photovoltaic panel 4 into a charging current suitable for the energy storage battery. The current stabilizer can use a linear current stabilizer to adjust the output current of the photovoltaic panel 4 to stabilize the output current, and can also adjust the output current according to actual needs. That is, the photovoltaic panel 4 can convert solar energy into electrical energy for charging and replenishing the energy storage battery. The energy storage battery stores the electrical energy generated by the photovoltaic panel 4 and is used to power the heating plate 241, which is beneficial to increase the service life of the heating plate 241 and reduce the frequency of manual replacement of the energy storage battery for replenishing power.

[0039] In one embodiment of the present application, see Figure 5 As shown, a battery box 42 is disposed below the photovoltaic panel 4 , and the battery box 42 is connected to the outer wall of the back plate 23 .

[0040] In the above embodiment, the battery box 42 is used to place the energy storage battery. The battery box 42 is used to accommodate and protect the energy storage battery, which is beneficial to improving the stability of the energy storage battery. The battery box 42 is arranged on the outer wall of the back plate 23 to facilitate the maintenance of the energy storage battery. The battery box 42 is arranged below the photovoltaic panel 4, and the photovoltaic panel 4 can protect the battery box 42 from rain to prevent water from entering the battery box 42 and causing a short circuit in the energy storage battery.

[0041] In one embodiment of the present application, Figure 5 As shown, a water outlet hole 5 is provided at the bottom of the back plate 23 , and a drainage groove 51 is provided outside the water outlet hole 5 , and the drainage groove 51 extends outward along the two side edges of the support frame 21 .

[0042] In the above embodiment, water leakage may occur when the fire hydrant body 1 is supplying water. If the water stays in the insulation chamber 2 for a long time, it will cause damage to the components in the insulation chamber 2. The water in the insulation chamber 2 can be discharged through the water outlet 5, and the drainage groove 51 extends to both sides of the support frame 21 to guide the water to a place away from the insulation chamber 2 for discharge to avoid water backflow.

[0043] In one embodiment of the present application, see Figure 6 As shown, a skylight hole 221 is opened on the top plate 22 , and a light-transmitting plate is installed in the skylight hole 221 .

[0044] In the above embodiment, a light-transmitting plate is installed in the skylight hole 221 to increase the light transmittance of the insulation cavity 2. Sunlight passes through the light-transmitting plate into the insulation cavity 2. Short-wave radiation in the sunlight passes through the light-transmitting plate and is absorbed by the inner surface of the insulation cavity 2, converted into heat and then released in the form of long-wave radiation. The light-transmitting plate has poor transmission of long-wave radiation and can retain heat in the insulation cavity 2, which is beneficial to increase the temperature in the insulation cavity 2 and prevent the fire hydrant body 1 from freezing.

[0045] In one embodiment of the present application, see Figure 6 As shown, a flashing light 222 is installed on the top plate 22 .

[0046] In the above embodiment, installing the flashing light 222 can increase the visibility of the exterior of the fire hydrant, especially at night or under severe weather conditions, which helps firefighters and other personnel to quickly locate the fire hydrant and initiate rescue operations in an emergency.

[0047] In the actual use of this application: the heat preservation chamber 2 is covered on the outside of the fire hydrant body 1, and the heat preservation chamber 2 includes a support frame 21, which is composed of a top plate 22, a back plate 23 and a bottom plate 24. A heating plate 241 is arranged on the upper end surface of the bottom plate 24, that is, a heating plate 241 is arranged in the heat preservation chamber 2 for heating the fire hydrant body 1, and a temperature sensor 231 is installed on the inner side of the back plate 23. The temperature sensor 231 is electrically connected to the heating plate 241. When the temperature sensor 231 detects that the temperature in the heat preservation chamber 2 is lower than the set temperature, the heating plate 241 starts to operate to ensure that the fire hydrant body is at a non-freezing temperature in the heat preservation chamber 2, and prevents the water in the fire hydrant body 1 from condensing and affecting the normal use of the fire hydrant body 1. The movable plate assemblies 3 are installed on both sides of the support frame 21. When in use, the movable plate assemblies 3 on both sides of the support frame 21 are opened, the water pipe is connected to the fire hydrant body 1, and the fire hydrant body 1 is opened to supply water for fire extinguishing.
