Description

Technical Field

[0001] The present invention relates to the technical field of water conservancy engineering, and in particular to a centralized water supply scheduling system for a household water tank group. Background Art

[0002] The Dashi Mountain area in northwest Guangxi is located on the southeastern edge of the Yunnan-Guizhou Plateau. It is a typical karst landform area. Most of the rainfall flows into the ground through karst fissures and limestone funnels, resulting in a shortage of surface water resources. The main way to solve the water problem of rural life and production is to build household water tanks to collect rainwater. Household water tanks are simple water storage tanks for households. They are usually cylindrical and made of concrete or mortar masonry. They are mostly built on relatively flat hillsides and have a capacity of 30m3. 3 ~300m 3 It is used to collect rainwater or seasonal mountain spring water as drinking water source.

[0003] However, due to the early construction period, traditional single-household water tanks are generally managed by the people themselves. There are problems such as substandard water quality, low water source security, and inadequate operation and maintenance. In addition, there are differences in water use among the people. Some people work away from home for a long time and rarely use water. The water in the water tanks is mostly surplus and easily becomes stagnant, resulting in substandard water quality and affecting its use. Some people stay at home for a long time and use a lot of water, resulting in less water in the water tanks. There is no water transmission and distribution network between the water tanks, and it is impossible to achieve reasonable allocation and management of water sources between the water tanks. In addition, rainwater and seasonal mountain spring water are easily contaminated by dead branches and leaves, dust, etc., which lead to the breeding of water microorganisms and algae, resulting in the deterioration of overall water quality. Summary of the Invention

[0004] The purpose of the present invention is to provide a centralized water supply scheduling system for a group of household water tanks with intelligent regulation, unified purification and disinfection, remote control, energy saving and environmental protection, so as to solve the technical problems of the existing single-household water tanks being scattered, unable to grasp the water volume in the water tanks in real time, poor water quality, and unable to achieve reasonable allocation and management of water sources between water tanks.

[0005] In order to solve the above technical problems, the solutions adopted by the present invention are as follows: A centralized water supply scheduling system for a group of household water tanks, comprising a water tank, a manual gate valve, an electric switch valve, a water pipe, a PLC system control cabinet, a management room, purification equipment, disinfection equipment, a clean water tank and a water level monitoring device; the water tanks are provided in plurality; the water pipes are provided in plurality; the water tanks are connected via the water pipes; the manual gate valve and the electric switch valve are installed on the water pipes; the purification equipment and the disinfection equipment are installed in the management room from left to right; the PLC system control cabinet is fixedly installed on one side inside the management room; the water tanks are connected to the purification equipment via the water pipes; the clean water tank is provided with two water supply pipes; one side of the clean water tank is connected to the disinfection equipment via the water supply pipe, and the other side is transported to the user via the water supply pipe; a manual valve is provided in the middle of the water supply pipe; the water level monitoring device is installed inside the water tank; the PLC system control cabinet is electrically connected to the electric switch valve, purification equipment, disinfection equipment and water level monitoring device.

[0006] Water tanks are used to store water. Several water tanks are connected in series and then in parallel through water pipes according to their elevations, from high to low, and then transported to a total water tank. The water is then transported to the purification equipment in the management room for purification, and then disinfected by the disinfection equipment. It flows into the clean water pool through the water supply pipe for storage, and finally transported to the user's home through the water supply pipe for use. The manual valve connecting the clean water pool, the disinfection equipment and the water user is in a normally open state. The water level in the water tank can be manually controlled by the staff manually operating the manual gate valve, or the PLC system control cabinet can monitor the water level in the water tank through the water level monitoring device and control the liquid level of the water tank by controlling the electric switch valve. It realizes the optimized regulation of water volume between water tanks, realizes the unified allocation of water resources as a whole, improves the water resource utilization rate of water tanks, effectively improves the convenience of water tank management, and also enhances the fluidity of water, avoiding the situation where water in the water tank that has not been used for a long time becomes stagnant water, and effectively improves the water quality compliance rate through unified purification and disinfection; when the water level is controlled by the electric switch valve, the manual gate valve is in the normally open state, and when the water level is controlled by the manual gate valve, the electric switch valve is in the normally open state; when cleaning the clear water pool, the manual valves at the connection end of the clear water pool, disinfection equipment and water user can be closed, which increases the convenience and practicality of cleaning the clear water pool.

[0007] Furthermore, the water tank is provided with a vent and a water outlet; the vent is provided at the top of the water tank; the water outlet is provided at the bottom of one side of the water tank; one end of the water pipe is connected to the water outlet of the previous water tank, and the other end is connected to the vent of the next water tank. The water outlet of the previous water tank is connected to the vent of the next water tank via the water pipe. In conjunction with the manual gate valve and the electric switch valve on the water pipe, the water in the previous water tank is transported through the water pipe to the vent pipe of the next water tank, and then into the next water tank, thereby maintaining the water level in the water tank.

[0008] Furthermore, the water tank is equipped with a vertical pole, a solar panel, and a solar battery distribution box. The bottom end of the vertical pole is fixedly mounted on the top of the water tank, and the top end is connected to the solar panel. The solar battery distribution box is fixedly mounted in the middle of the vertical pole and is electrically connected to the water level monitoring device and the electric switch valve. The solar panel at the top of the vertical pole absorbs solar energy to generate electricity, which is stored in the solar battery distribution box. The solar battery distribution box then supplies power to the water level monitoring device and the electric switch valve. This reduces overall reliance on traditional electricity, improves the environmental friendliness and cost-effectiveness of the system, and facilitates the connection of multiple water tanks, reducing the cost of long-distance wiring for power supply.

[0009] Furthermore, the water tank is provided with an internal float level gauge; the internal float level gauge includes a display, a converter, a flange, an upper limiter, a float, a measuring tube and a lower limiter; the display is located in the middle of the top of the water tank, and the bottom end is fixedly connected to the measuring tube; the flange is located directly below the display; the measuring tube is installed in the middle of the top of the water tank through the flange; the bottom end extends into the water tank; the float is sleeved on the measuring tube; the upper limiter is fixedly installed on the upper end of the measuring tube; the lower limiter is fixedly installed on the lower end of the measuring tube; the converter is fixedly installed on the top of the display. The internal float level gauge is designed based on the Archimedean buoyancy principle and magnetic coupling. The float with a magnet is affected by the buoyancy of the water in the water tank and slides up and down on the measuring tube due to changes in the water level. A sensor is installed inside the measuring tube. When the water level in the water tank changes, that is, the position of the float changes, the magnet inside the float triggers the sensor in the measuring tube, causing its internal resistance value to change. The water level in the water tank is displayed on the display, and the signal of the resistance change is transmitted to the converter, which is converted into a data signal and transmitted to the PLC system control cabinet for remote monitoring and control. The display can display the water level of the water tank on site, which is convenient for staff to check on site. The upper limit switch and the lower limit switch are used to prevent the water level in the water tank from being too high or too low. When the water level reaches the upper and lower limits, the signal is converted and transmitted to the PLC system control cabinet through the converter to alarm, notifying staff to carry out maintenance.

[0010] Furthermore, the water tank is provided with an inspection hatch located at the top of the tank and fitted with a matching cover. When the tank requires maintenance, staff can open the cover and access the tank through the hatch for inspection and repair, facilitating both routine maintenance and emergency repairs.

[0011] In order to better supply water, a water pump can be added to the water pipe as needed. The water pump and the valve are connected in series, and the water tank is equipped with a special water diversion device to introduce rainwater or surface water into the water tank through an external water diversion pipe.

[0012] The working principle of the present invention is as follows: Water is stored in water tanks, and all water tanks are connected in series and parallel through water pipes. The water level in the water tank is monitored in real time by the float inside the water tank. When the water level in the previous water tank is too high, the float and measuring tube in the water tank transmit the value to the display for display. At the same time, the value is converted and transmitted to the PLC system control cabinet through the converter. The PLC system control cabinet controls the opening of the electric switch valve to transport water to the next water tank, realizing water volume regulation between water tanks. When the water in the water tank flows to the last main water tank, the water flows to the purification equipment for filtration and purification to remove impurities, and is then transported to the disinfection equipment for disinfection and then to the clean water tank for storage. Finally, it is transported to the user's home when the user uses it. If the water tank is damaged and needs repair or the inside of the water tank needs cleaning, the inside of the water tank can be entered through the inspection port for cleaning and maintenance. The water level monitoring device and the electric switch valve are powered by solar power generation. No external power supply is required as the whole system, which reduces energy consumption and reduces dependence on traditional electricity.

[0013] The beneficial effects of the present invention are as follows: 1. The present invention connects water tanks through water pipes, monitors the water level through the water level monitoring device inside the water tank and transmits it to the control cabinet for real-time monitoring and remote operation. By remotely controlling the opening and closing of the electric switch valve, the water level in the water tank can be adjusted, and the water volume between different water tanks can be uniformly allocated and managed, thereby improving the water resource utilization rate of the water tank and the fluidity between water tanks, thereby improving the water quality assurance level.

[0014] 2. The present invention can realize real-time monitoring of the water level in the water tank by arranging an internal float level gauge in the water tank, transmit the signal to the PLC system control cabinet to realize remote monitoring, and can remotely and automatically adjust the water level in the water tank in combination with the electric switch valve. The solar power supply system provides energy for the water level monitoring device and the electric switch valve, reducing dependence on traditional electricity, reducing operating costs, and improving the environmental protection and economy of the system.

[0015] 3. The inspection port provided on the top of the water tank of the present invention facilitates the staff to enter the water tank for daily maintenance, inspection and repair of sudden failures, ensuring the long-term stable operation of the system and reducing the maintenance workload and time cost.
