[0002] High-rise residential buildings, for evacuation purposes, require two stairwells on each floor. To maximize floor space utilization, developers often connect two buildings via corridors, allowing them to share a common stairwell. This design does meet evacuation requirements, but the open design of the corridors exposes the domestic water supply pipes directly or indirectly to the air. Especially in winter, the water in the pipes freezes due to temperatures below its freezing point, causing ice formation and even bursts, seriously impacting residents' daily lives.

[0030] The specific implementation methods of the present invention are described in detail below through examples. These examples are implemented on the premise of the scheme described in the present invention, and provide detailed implementation methods and specific operating processes, but the protection scope of the present invention is not limited to the following examples.

[0031] The present invention is further described below with reference to the accompanying drawings and specific embodiments. Any features, such as component models, material names, connection structures, preparation methods, materials, structures, or composition ratios, that are not explicitly described in this technical solution are considered to be common technical features disclosed in the prior art.

[0032] Example 1

[0033] This embodiment provides a pipe heating device for a residential corridor, such as Figures 1 to 3 As shown, the system includes a control box 3, an electric heating assembly, and a thermometer 7. The electric heating assembly is connected to the control box 3. The thermometer 7 is fixed to the exterior wall of the residential corridor and is in communication with the control box 3. The thermometer 7 is used to provide signals for switching between the electric heating assembly and the lighting assembly. The lighting assembly is a corridor light 10, which is installed at the top of the residential corridor and is used to illuminate the corridor at night. The control box 3 is fixed to the interior wall of the corridor using steel straps 9.

[0034] The electric heating assembly includes a solar panel 1 and an electric heating cable 6. The solar panel 1 is fixed to the outside of the residential corridor. The solar panel 1 is used to absorb sunlight and convert it into electrical energy and store it in the control box 3.

[0035] An electric heating cable 6 is laid along the outer edge of the domestic water supply pipe 5 between the residential corridors. One end of the heating cable 6 is connected to the control box 3, and the other end is fixed to the outside of the domestic water supply pipe 5. The heating cable 6 is fixed to the outside of the domestic water supply pipe 5 using heat-sensitive tape. Aluminum foil tape is applied horizontally over the heating cable 6 to ensure close contact with the domestic water supply pipe 5, improving thermal efficiency. The outside of the domestic water supply pipe 5 is provided with insulation material 8, which includes an inner layer of 50 mm thick ultra-fine glass wool and an outer layer of 0.3 mm thick aluminum foil.

[0036] The residential corridor includes a corridor outer wall 11 , a corridor floor 12 and a corridor cushion 13 which are fixed in sequence. The solar panel 1 is fixed on the corridor outer wall 11 , and the domestic water supply pipe 5 is fixed on the corridor cushion 13 .

[0037] The control box 3 is provided with a control panel 4 and a battery 2. The control panel 4 is used to switch between the electric heating component and the lighting component. The control panel 4 uses an industrial-grade MCU as the main controller, which is responsible for monitoring and controlling the working state of the entire device. By measuring the ambient temperature and detecting parameters such as the voltage and current of the battery and solar cell components, it controls the opening and closing of the MOSFET device to achieve control and protection functions for the entire device. The control panel is provided with two independent MOSFETs (metal oxide semiconductor field effect transistors) that act as electronic switches in this device and are responsible for controlling the flow of current. Each switch is controlled by a control signal provided by the main controller. The control panel used in this embodiment is existing technology and was purchased, so it will not be repeated here. The battery 2 is used to store the electrical energy converted by the solar panel 1 and to power the electric heating component and the lighting component.

[0038] The specific operation process is as follows: When the thermometer 7 detects that the ambient temperature is below 0°C, the thermometer 7 sends a feedback signal to the control box 3. The control panel 4 in the control box 3 activates the MOSFET of the electric heating assembly, heating and insulating the domestic water supply pipe 5 through the electric heating cable 6 to prevent it from freezing. At this time, the MOSFET of the lighting assembly is in the off state. When the thermometer 7 detects that the ambient temperature is above 0°C, the control panel 4 in the control box 3 disconnects the MOSFET of the electric heating assembly and activates the MOSFET of the lighting assembly. The lighting assembly uses the electricity collected during the day to supply the corridor lights 10 at night. The lighting assembly is equipped with a photoresistor. Due to the characteristics of the photoresistor being high in resistance during the day and low in resistance at night, nighttime lighting is achieved.

[0039] During the entire process, the MCU will control the on and off of the MOSFET by changing the gate-source voltage of the MOSFET according to actual needs and detected parameter changes, thereby achieving the purpose of controlling the power supply to the load and protecting the battery from overcharging or over-discharging. Two independent MOSFETs are provided in the control panel, acting as electronic switches for the electric heating component and the lighting component. An interlocking mechanism is used in the device to achieve this function. Interlocking is a safety measure used to prevent two subsystems from working at the same time, thereby avoiding possible conflicts or damage. When the switch of one subsystem is activated (closed), the control unit should automatically disconnect the switch of the other subsystem. The control method and control logic used in this embodiment are conventional methods used in the prior art and will not be repeated here.

[0040] The above description of the embodiments is intended to facilitate understanding and use of the utility model by those skilled in the art. Those skilled in the art will readily be able to make various modifications to these embodiments and apply the general principles described herein to other embodiments without requiring inventive effort. Therefore, the utility model is not limited to the above-described embodiments. Improvements and modifications made by those skilled in the art based on the disclosure of this utility model without departing from the scope of this utility model should be within the scope of protection of this utility model.
