[0024] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0025] In the related art, in a low-temperature and cold environment, general rail transit stations are outdoors, and underground wells are also outdoors, which cannot fully insulate the water supply equipment, resulting in freezing inside the equipment in harsh environments, and water pipes or internal meter valves cannot be used normally.

[0026] In order to solve the above technical problems, Figure 1 As shown, at least one embodiment provides a water supply device for cold environments, including: a chassis 1, a side wall of the chassis 1 is provided with a pipe release port 14, and the water pipe inside the chassis 1 can be unwound and reeled through the pipe release port 14. A key panel 3 is also installed on the same side wall as the pipe release port 14, and the key panel 3 has a reeling button. When unwinding, the water pipe can be manually pulled out from the pipe release port 14, and when reeling, the reeling button can be pressed to automatically reel the water pipe. At the same time, Figure 2As shown, several heaters 2 are installed inside the chassis 1. When the heaters 2 are turned on, the inside of the chassis 1 can be heated to keep the inside of the chassis 1 warm in a cold environment, so that the inside of the chassis 1 is kept within the operating temperature range, thereby avoiding freezing inside the equipment and the inability of water pipes or meter valves to work. Optionally, the types of heaters include, but are not limited to, electromagnetic heaters, infrared heaters, and resistance heaters. The above operating temperature refers to a state in which the water supply equipment is in an operational state and there is no freezing inside the water pipes, that is, a state greater than 0 degrees Celsius. To be on the safe side, the heater 2 maintains the internal temperature range of the chassis 1 at 5-20°C.

[0027] Further, if Figure 2 As shown, a meter valve cabinet 11 is also installed inside the chassis 1. The meter valve cabinet 11 is sealed by a cabinet door and a cabinet wall to separate it from other devices inside the chassis 1, so as to avoid water leakage inside the chassis 1 and protect the devices inside the meter valve cabinet 11. In order to enhance the heating effect of the meter valve cabinet 11, the meter valve cabinet 11 has at least one heater 2. Preferably, the number of heaters 2 is two, that is, there is a heater 2 in the cavity of the chassis 1, and there is also a heater 2 inside the meter valve cabinet 11. The two heaters 2 respectively keep the inner cavity of the chassis 1 and the inner cavity of the meter valve cabinet 11 within the operating temperature range to ensure that the equipment can operate normally during water supply work, adapt to the cold environment and reliably complete the water supply work. Preferably, valves and pressure gauges are placed in the meter valve cabinet 11.

[0028] In order to realize the operation of the equipment, Figure 2 As shown, there is an electrical cabinet 13 on one side of the meter valve cabinet 11, and each button is electrically connected to the electrical cabinet 13. There is a motor inside the electrical cabinet 13, and the motor is connected to the retractable disk 12 by transmission. Several buttons on the key panel 3 can control the operation of the motor inside the electrical cabinet 13, thereby driving the retractable disk 12 to rotate, and achieve the effect of reeling in the water pipe. The retractable disk 12 is arranged horizontally, and the retractable disk 12 is located on the top of the chassis 1, so the overall equipment can be used as a semi-buried equipment. A pipe release port 14 is provided on the chassis 1, and the pipe release port 14 is consistent with the height of the retractable disk 12, which is convenient for extracting the water pipe for use. The layout of the above-mentioned retractable disk 12 allows the meter valve cabinet 11, the electrical cabinet 13 and the heater 2 to be closely arranged under the retractable disk 12, so the overall height of the equipment is small, and it can be used as a depot, thereby facilitating the use of the equipment.

[0029] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
