Description

Technical Field

[0001] The utility model relates to the technical field of water purification equipment, in particular to a water leakage detection device for water purification equipment. Background Art

[0002] With the improvement of people's living standards, water purification equipment has entered thousands of households and made contributions to the drinking water health of the general public. However, there is always a shadow in the water purification equipment industry, that is, leakage.

[0003] For the existing water leakage detection devices of water purification equipment, for example, a water leakage detection device for a cabinet-type water purification equipment disclosed in the utility model patent with the application number 201320658001.6, its main structure includes a housing. A filter pipe is installed in the housing. A drawer is arranged below the filter pipe. A chassis is arranged below the drawer. The drawer includes a drawer bottom plate, a front baffle, and two side frames and a panel distributed along the moving direction of the drawer. A water leakage detection device is arranged at the connection between the outer side surfaces of the side frames and the panel and the front baffle. The water leakage detection device includes a detection electrode and a fixing device for fixing the detection electrode. The chassis is provided with a water accumulation tank. The end of the sensor extends into the water accumulation tank. When water leakage occurs, the water flows into the water accumulation tank of the chassis. The detection electrode senses the accumulated water in the water accumulation tank and detects a signal. Then, this signal can be further sent to a circuit control board, and the circuit control board outputs a control signal to an automatic water inlet solenoid valve to close the water inlet solenoid valve.

[0004] However, most of the existing water leakage detection devices are difficult to determine the water leakage point, which is not convenient for personnel to repair the water inlet equipment in time. Moreover, most of the existing water leakage detection devices cannot directly drain the leaked water. Excessive accumulated water stored in the water collection tank still has the risk of leakage. Summary of the Utility Model

[0005] To solve the above technical problems, the utility model provides a water leakage detection device for water purification equipment that is not only convenient for detecting the water leakage point, facilitating subsequent maintenance by staff, but also can drain the leaked water in time to avoid water accumulation in the water purification equipment.

[0006] A water leakage detection device for a water purification device of the present utility model includes a purification mechanism; it further includes a water conveyance mechanism, three velocity measurement mechanisms, a detection mechanism, and a drainage mechanism. The water conveyance mechanism is installed on the purification mechanism to facilitate the inflow and outflow of water. The three velocity measurement mechanisms are all installed on the purification mechanism to detect the flow velocity at the water flow nodes. The detection mechanism is installed on the purification mechanism to detect the water leakage point. The drainage mechanism is installed on the purification mechanism to promptly drain the leaked water; the water conveyance mechanism is internally connected to the water inlet pipe and the drainage pipe. Water enters the purification mechanism through the water conveyance mechanism for purification. The three velocity measurement mechanisms detect the flow velocity of the passing water to assist in judging the water leakage point. The detection mechanism and the drainage mechanism detect the leaked water and drain it out.

The first purification tank conveys the water after primary filtration to the second purification tank through the velocity measurement mechanism for secondary filtration. The water after secondary filtration is discharged through the water conveyance mechanism. The electric control system controls each detection device and displays whether there is water leakage and the water leakage position through the display screen, facilitating maintenance by the staff.

[0008] Preferably, the water conveyance mechanism includes a water inlet pipe, a first manual valve, a first solenoid valve, a water outlet pipe, and a second manual valve.

When the detection mechanism and the drainage mechanism detect water leakage, the electric control system closes the first solenoid valve through an electric signal to prevent water flow from entering.

[0009] Preferably, the velocity measurement mechanism includes a water conveyance pipe, a rotating shaft, four groups of blades, and a speed sensor. The three water conveyance pipes are respectively installed between the water inlet pipe and the first purification tank, between the first purification tank and the second purification tank, and between the second purification tank and the water outlet pipe. The rotating shaft is rotatably installed on the water conveyance pipe. The four groups of blades are all installed on the rotating shaft. The speed sensor is installed on the water conveyance pipe; water flow pushes the blades through the water conveyance pipe, and the blades drive the water conveyance pipe to rotate. The speed sensor detects the rotation speed of the water conveyance pipe. By setting three velocity measurement mechanisms, it is convenient to detect the flow velocity at different positions. When it is detected that the flow velocity of the speed sensor suddenly decreases, it indicates that water leakage has occurred on the front side of this group of velocity measurement mechanisms, and the flow velocity is transmitted to the electric control system through an electric signal.

[0010] Preferably, it further includes a second solenoid valve installed on the water pipe located between the first purification tank and the second purification tank; when the speed sensor detects a sudden decrease in the water flow rate, the second solenoid valve is activated to block the water pipe, preventing water from flowing from the first purification tank into the second purification tank and reducing the amount of leaked water.

When the water level in the water collecting tank reaches a certain level, the water pump is activated. The water pump pumps out the water in the water collecting tank through the pumping hose, and then discharges the water into the sewer through the drainage pipe. At the same time, the water collecting tank is pulled out through the handle to pour out the remaining water in the water collecting tank.

When it works, first, connect the water inlet pipe 21 to the water source, connect the water outlet pipe 24 to the faucet, open the first manual valve 22 and the second manual valve 25. Water enters the first purification tank 14 through the water inlet pipe 21 and the speed measuring mechanism 03 for filtration. The first purification tank 14 conveys the water after primary filtration to the second purification tank 15 through the speed measuring mechanism 03 for secondary filtration. The water after secondary filtration is discharged through the water outlet pipe 24. The water flow pushes the blade 33 through the water delivery pipe 31, and the blade 33 drives the water delivery pipe 31 to rotate. The speed sensor 34 detects the rotation speed of the water delivery pipe 31. By setting three groups of speed measuring mechanisms 03, it is convenient to detect the water flow rates at different positions. When it is detected that the water flow rate of the speed sensor 34 suddenly decreases, it indicates that water leakage has occurred in the front side of this group of speed measuring mechanisms 03. The water flow rate is transmitted to the electronic control system 12 through an electric signal.

When the water leakage sensor 53 detects that there is water in the water collecting tank 51, it is transmitted to the electronic control system 12 through an electric signal. The electronic control system 12 starts the second solenoid valve 35 to block the water delivery pipe 31, preventing the water flow from flowing from the first purification tank 14 into the second purification tank 15 and reducing the amount of leaked water. The electronic control system 12 closes the first solenoid valve 23 through an electric signal to prevent water from entering. When the water level in the water collecting tank 51 reaches a certain level, the water pump 54 is started.
