Description

TECHNICAL FIELD

[0002] In modern urban water supply systems, to meet the water demand of high-rise buildings and regions, secondary water supply has become a common and important means of water supply. The existing secondary water supply structure generally consists of a water source, a water storage facility, a water pump unit, a pressure sensor, a control system and a water supply network. The water from the water source first flows into the water storage facility, such as a water tank or a water pool, for storage. The water storage facility plays a role in buffering and adjusting the water volume to cope with fluctuations in water consumption. Then, the water pump unit extracts water from the water storage facility and delivers water to various water consumption points through the water supply network. The water pump unit generally consists of multiple water pumps, which can control the start and stop of the water pump and adjust the speed of the water pump through the control system according to the actual water consumption, so as to realize constant pressure water supply. However, the existing secondary water supply constant pressure water supply device has the following problems:

[0003] 1. When the water consumption changes, due to the detection and feedback delay of the pressure sensor, the control system cannot adjust the speed of the water pump in time. For example, during the peak period of water consumption, the water consumption suddenly increases, and the pressure sensor detects the pressure drop and feeds back to the control system, resulting in a time difference, so that the water pump cannot increase the speed in time to supplement the water volume, and the whole device stops working.

[0004] 2) The existing water supply device does not have a corresponding mechanism to prevent corrosion of the metal inner container. During long-term use, factors such as dissolved oxygen and pH in water can cause corrosion of the metal inner container in the water supply device, shortening the service life of the device.

[0031] Please refer to Figures 1 to 4 The embodiment provides a novel water supply device based on RFID, which comprises a water storage tank 1, a shunt pipe 2, a plurality of branch pipes 3, a water outlet pipe 4 and a control cabinet 5. The drain 101 of the water storage tank 1 is communicated with the water inlet ends of the plurality of branch pipes 3 through the shunt pipe 2, and the water outlet ends of the plurality of branch pipes 3 are communicated with the water outlet pipe 4. Through the shunt effect of the plurality of branch pipes 3, different water use conditions can be more flexibly adapted, and the stability and reliability of water supply are improved. The flow sensor 6 and the pressure pump 7 are arranged on each branch pipe 3, a magnesium rod 8 is arranged in the metal inner container of the water storage tank 1, and the control cabinet 5 is electrically connected with the flow sensor 6, the pressure pump 7 and the magnesium rod 8.

[0032] Wherein, by setting flow sensor 6 and pressurizing pump 7 on each branch pipe 3, when flow sensor 6 detects the increase of flow, pressurizing pump 7 controls the flow of pump by adjusting the opening of inlet valve and outlet valve to make the water pressure drop; when flow sensor 6 detects the decrease of flow, pressurizing pump 7 controls the flow of pump by adjusting the opening of inlet valve and outlet valve to make the water pressure increase; compared with the traditional way of relying on pressure sensor to detect feedback, flow sensor 6 can more timely and accurately perceive the change of flow, so that pressurizing pump 7 can quickly respond and adjust the flow, avoiding the problem that the speed of water pump cannot be adjusted in time due to the detection and feedback delay of pressure sensor, ensuring that the water supply device can operate stably when the water consumption changes, effectively preventing the device from stopping working due to unstable water pressure.

[0033] Control cabinet 5 can receive the signal of flow sensor 6, control the working state of pressurizing pump 7 according to the change of flow, realize the dynamic adjustment of water pressure, and it can also control the working of magnesium rod 8, when the metal liner has local cracks, provide current for magnesium rod 8, so as to start the anti-corrosion protection mechanism, ensure the normal operation and maintenance of the whole water supply device.

[0034] When the metal liner has local cracks, control cabinet 5 provides current for magnesium rod 8, a small resistance is formed between magnesium rod 8 and metal liner through water, magnesium rod 8 starts to output current, flows to the exposed metal liner to produce a kind of polarization film, repairs the damaged metal liner, and insulates the metal liner to prevent corrosion. This setting effectively solves the corrosion problem of metal liner in existing water supply device caused by dissolved oxygen, acid-base value and other factors in water, prolongs the service life of water supply device, and reduces the replacement and maintenance cost of equipment.

[0035] Water storage tank 1, shunt pipe 2, each branch pipe 3, water outlet pipe 4, pressurizing pump 7 and control cabinet 5 are respectively installed with RFID electronic tags with unique codes, and each RFID electronic tag is installed with an RFID reader 9 electrically connected with control cabinet 5 opposite to it. RFID electronic tags store detailed information of corresponding equipment components, such as equipment model, manufacturer, production date, batch number, maintenance record, etc. By installing RFID electronic tags on each equipment component and cooperating with RFID reader 9 set opposite to the tags, real-time tracking of equipment running state can be realized, compared with the traditional manual recording or query method, the efficiency of obtaining equipment information is greatly improved, and the basic attributes of the equipment can be understood more timely, providing basic data support for the management and maintenance of the equipment.

When the water level reaches a certain height, the float valve 104 is closed to prevent water overflow and ensure the stability of the water level in the water storage tank 1, thereby avoiding water resource waste and possible equipment damage. The water outlet 101 is arranged at the bottom of the water storage tank 1, which is beneficial to completely discharge the water in the water storage tank 1. At the same time, in the case of sedimentation of impurities and the like, the impurities will be deposited at the bottom, and part of the impurities can be discharged together when discharging water, which helps to keep the water quality in the water storage tank 1 clean.

[0037] Please refer to Figure 1 、 Figure 2 In one embodiment, the water outlet 101 is communicated with the water inlet end of the shunt pipe 2 through a flange, the water outlet end of the shunt pipe 2 is communicated with the water inlet end of each branch pipe 3 through a flange respectively, and the water inlet end of each branch pipe 3 is communicated with the water inlet end of the outlet pipe 4 through a flange.

[0038] Please refer to Figure 1 、 Figure 2 In one embodiment, the branch pipe 3 is provided with two pipes which are arranged side by side. The side-by-side arrangement of the two branch pipes 3 can increase the flow and stability of water supply to a certain extent. When one of the branch pipes 3 fails or needs to be maintained, the other branch pipe 3 can still work, thereby ensuring part of the water supply demand and improving the reliability and fault tolerance of the water supply system.

[0039] Please refer to Figure 3In one embodiment, the magnesium rod 8 is fixed to the inner bottom of the metal liner by screws. By fixing the magnesium rod 8 by screws, the installation method is simple and reliable, and it is convenient to install, replace and maintain the magnesium rod 8.

In addition, an insulating resistor is provided between the magnesium rod 8 and the metal liner, and the resistance value of the insulating resistor is 2MΩ or more, to avoid unnecessary electrochemical reactions of the magnesium rod 8. Only when the metal liner has a local crack and the control cabinet 5 provides current to the magnesium rod 8, a small resistance path is formed between the magnesium rod 8 and the metal liner through water, and the magnesium rod 8 starts to output current to repair the damaged metal liner.

[0040] Referring to Figure 1 , Figure 3 In one embodiment, the bottom of the water storage tank 1 is provided with a fixing frame, which can support and fix the water storage tank 1, keep the water storage tank 1 stable during use, and prevent it from affecting its normal work due to shaking or displacement. In the embodiment application, the fixing frame can be adjusted according to the actual installation environment to ensure that the water storage tank 1 is installed in the appropriate position, improving the flexibility and adaptability of the device installation.

[0041] Referring to Figure 1 In one embodiment, the bottom of the pressurizing pump 7 is provided with a fixed iron plate, which provides a stable installation basis for the pressurizing pump 7, makes the installation of the pressurizing pump 7 more firm, prevents connection loosening or component damage caused by vibration and other reasons, and improves the stability and reliability of the water supply system.

[0042] Referring to Figure 1 , Figure 2 In one embodiment, the second connecting flange 401 is arranged at both ends of the water outlet pipe 4, which facilitates the connection of the water outlet pipe 4 with the resident water pipe, and improves the construction efficiency.

[0043] In one embodiment, the metal liner is a enamel liner. The enamel liner has good corrosion resistance, can effectively resist the corrosion of the metal liner caused by dissolved oxygen, acid-base degree and other factors in water, further prolongs the service life of the water storage tank 1, and reduces the equipment replacement and maintenance cost caused by liner corrosion. At the same time, the surface of the enamel liner is smooth and not easy to attach impurities and scale, which helps to keep the water quality in the water storage tank 1 clean and improves the quality of water supply.

[0044] In one embodiment, the new water supply device based on RFID further comprises a measuring device for measuring the resistance value of the metal liner, and the measuring device is electrically connected with the control cabinet 5. The measuring device can monitor the resistance value change of the metal liner in real time or at intervals (such as one day), and through the electrical connection with the control cabinet 5, the resistance value information is fed back to the control cabinet 5. When the metal liner has abnormal conditions such as cracks, the resistance value will change, and the control cabinet 5 can make a judgment in time according to the resistance value change, whether to start the anti-corrosion protection mechanism of the magnesium rod 8, and the intelligent degree and fault warning capability of the water supply device are improved.

[0045] The measuring device can measure the resistance value of the metal liner by using a constant current source method, an alternating current impedance method or a bridge method, and the present application does not limit this. It should be noted that the constant current source method, the alternating current impedance method or the bridge method are prior art, and therefore the specific structure and working principle of the present application will not be described in detail.

[0046] It should be understood that those skilled in the art can make improvements or changes according to the above description, and all these improvements and changes should belong to the protection scope of the appended claims of the present application.
