Description

Technical Field

[0001] The utility model belongs to the technical field of floor heating pipeline monitoring, and particularly relates to a floor heating water leakage protection device. Background Art

[0002] Due to limitations in floor heating technology and pipe materials, floor heating presents numerous potential safety risks. Floor heating involves piping hot water beneath the floor, heating the interior space through radiant heat. Because the pipes must pass underground during installation and lack reliable leak protection, they present a potential safety hazard.

[0003] On the one hand, floor heating pipes are affected by many factors during the installation process, such as the quality of pipes and valves, installation technology, construction quality, etc. If these factors are not reasonably resolved and controlled, it may cause pipe leakage; on the other hand, if the floor heating pipes are used for too long, they will be affected by factors such as sunlight radiation, water quality, and natural environment, and the pipes will age, resulting in aging of the pipe materials and reduced elasticity, thereby increasing the risk of pipe leakage.

[0004] The dangers of leaking underfloor heating pipes: Leaking underfloor heating pipes waste hot water, increasing energy consumption and expenses. Furthermore, leaking pipes can damage flooring, furniture, and other items, increasing repair and replacement costs. Leaking underfloor heating pipes can cause hot water loss, reducing heating efficiency and affecting indoor temperature control. Prolonged exposure to humidity can lead to mold growth, potentially weakening the body's immune system. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making any creative work are within the scope of protection of the present invention.

Therefore, they have no substantive technical significance.

It should be noted that in this specification, relational terms such as first and second are only used to distinguish one entity from several other entities, and do not necessarily require or imply any actual relationship or order between these entities.

[0021] The present invention provides an embodiment:

[0022] like Figures 1 to 4As shown, a floor heating water leakage protection device includes a controller, a pressure sensor, a relay, a contactor, a solenoid valve and a buzzer; the pressure sensor is placed in the floor heating pipe to detect and collect the water pressure signal in the floor heating pipe; the solenoid valve is used to control the water flow of the electric heating pipe;

[0023] The signal input end of the controller is connected to a pressure sensor, and the signal output end of the controller is connected to a relay, a solenoid valve and a buzzer;

[0024] The relays include overcurrent relay KA1 and overcurrent relay KA2, and the contactors include contactors KM1 and contactors KM2; the normally open contact of the overcurrent relay KA1 is connected in series with the coil of the contactor KM1 and is connected to the three-phase power supply to form a first circuit; the normally open contact of the contactor KM1 is connected in series with the indicator light HG1 and is connected to the three-phase power supply to form a first indication circuit; the normally open contact of the overcurrent relay KA2 is connected in series with the coil of the contactor KM2 and is connected to the three-phase power supply to form a second circuit; the normally open contact of the contactor KM2 is connected in series with the indicator light HR1 and is connected to the three-phase power supply to form a second indication circuit.

[0025] In this embodiment, the plastic housing of the water leak protector is primarily made of polymers such as polyethylene (PE), polypropylene (PP), and epoxy (EP). It is lightweight, insulating, corrosion-resistant, and impact-resistant, resisting deformation and withstanding certain external forces. It also offers thermal insulation, enabling operation in high-temperature environments, and is environmentally friendly, meeting environmental protection requirements.

[0026] The relay and contactor are arranged inside the housing of the water leakage protection device. The button end of the controller and the pressure sensor extends to the front of the housing of the water leakage protection device. The buzzer, indicator light HG1 and indicator light HR1 are also located on the front of the housing of the water leakage protection device. The front of the housing of the water leakage protection device is also provided with a pressure value display screen.

[0027] The system also includes a UPS (uninterrupted power supply) whose charging terminal is connected to a three-phase power source via a rectifier. The UPS's output is then fed to the controller and circuit via an inverter. If a power outage occurs during household electricity use, such as at the main distribution or distribution system, the UPS, built into the leak protector, will close immediately when the circuit is disconnected, utilizing its own stored energy to continuously monitor for leaks in the floor heating system. If the power distribution system is operating normally, the USP remains disconnected and enters storage mode.

[0028] The controller's main control chip is a SIMATIC S7-200. An AC-DC converter is connected between the controller's power supply and the three-phase power supply. The pressure sensor is connected to the controller's signal input terminal, I0.0. Overcurrent relays KA1 and KA2, the solenoid valve, and the buzzer are connected to the controller's signal output terminals, Q0.0, Q0.1, Q0.2, and Q0.3, respectively.

[0029] Working principle:

[0030] If a floor heating pipe leaks, the pressure will fluctuate significantly, as it maintains a constant pressure during normal operation. When the pressure drops to the warning level of the leak protection device, the pressure sensor collects the pipe water pressure signal and transmits it to the controller. Based on the pressure signal, the controller sends a control signal to overcurrent relay KA2, energizing its coil and closing its normally open contacts. This connects the first circuit and energizes the coil of contactor KM2. This closes the normally open contacts of contactor KM2, connects the first indicator circuit, and illuminates red indicator light HR1. Simultaneously, based on the pressure signal, the controller sends a high-level signal to the buzzer and solenoid valve, triggering the buzzer to sound an alarm and the solenoid valve to shut off, shutting off the water supply. This device effectively alerts those near the manifold if a leak is detected in the floor heating pipe, preventing unsafe conditions.

[0031] If the floor heating pipe is operating normally, the pressure sensor collects the pipe water pressure signal and transmits it to the controller. The controller gives the overcurrent relay KA1 a control signal according to the pressure signal. The coil of the overcurrent relay KA1 is energized, the normally open contact of the overcurrent relay KA1 is closed, the second circuit is connected and the coil of the contactor KM1 is energized, and then the normally open contact of the contactor KM1 is closed, the second indication circuit is connected and the indicator light HG1 lights up green; at the same time, the controller controls the buzzer and the solenoid valve according to the pressure signal and does not operate.

[0032] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
