Description

Technical Field

[0001] The present invention relates to the technical field of intelligent concrete maintenance water supply and drainage systems, and in particular to an intelligent concrete building maintenance water supply system. Background Art

[0002] Concrete is one of the most commonly used materials in building and infrastructure construction, with advantages such as high strength and good durability. However, during the construction and use process, concrete will be affected by many factors, such as large temperature difference between the surface and the interior of the concrete, unreasonable water-cement ratio, direct sunlight causing the concrete surface to dry, etc., which will lead to its performance degradation and shorten its service life. In order to extend the service life of concrete and improve its performance, concrete needs to be scientifically maintained. During the maintenance process, the reasonable design and application of the water supply and drainage system are crucial. At present, in the field of technical research on intelligent concrete maintenance water supply and drainage system, the water for construction site maintenance still relies on traditional manual "pure pipeline" water supply. Mechanical valves are used at water points, and someone needs to open and close them. It is easy to cause improper operation to cause valve damage or negligent switch operation to cause waste of hydraulic resources and damage to devices.

[0003] At the same time, as the construction of the building continues, the height of the floor or wall panels that need to be maintained continues to increase. The existing conventional maintenance water supply method is difficult to achieve stable water supply, resulting in unstable water outlet pressure of the water supply pipeline. Maintaining a constant water pressure at the outlet is to prevent the water supply height from being insufficient or the water pressure from being too high from causing damage to the building surface. The construction site has to replace the water pump in time to meet the maintenance needs of high-rise buildings, which is time-consuming and laborious.

[0004] Therefore, it is of great significance to realize intelligent management and control of maintenance water supply, reduce waste of human resources, water loss and device loss, and thus realize intelligent maintenance of concrete buildings. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide an intelligent maintenance water supply system for concrete buildings, in which a variable frequency water pump works in an intelligent manner with a pressure sensor and a height sensor, thereby realizing real-time intelligent adjustment of the water outlet pressure of the intelligent concrete maintenance water equipment through a central controller, thereby ensuring that as the height of the building construction changes, the intelligent maintenance water supply system of the present invention can stably supply water at the set water pressure.

[0082] Example 3

[0083] Embodiment 3 includes all the technical features of Embodiment 2. On this basis, the frequency conversion adjustment of the variable frequency water pump in step 3 aims at minimizing energy consumption. According to the constraints such as the relative height of the concrete intelligent curing water equipment, the length of the water outlet pipe, and the power of the variable frequency water pump, an optimization model is established. The optimization model is expressed as follows:

[0084]

[0085] Among them, P pump (t) is the power of the variable frequency water pump at time t;

[0086] P supply (t) is the water supply pressure of the water supply system at time t;

[0087] P req(t) is the required water supply pressure at time t.

[0088] Example 4

[0089] Embodiment 4 includes all the technical features of Embodiment 1, and on this basis, further includes an air boosting mechanism, the air boosting mechanism includes an air compression pump, an air regulating component and an air supply pipeline, the inlet and outlet of the air supply pipeline are respectively connected to the air compression pump and the air inlet of the water tank, the air regulating component is arranged on the air supply pipeline, the air regulating component is used to open and close the air supply pipeline, the air compression pump is used to provide pressurized gas, the air regulating component includes a check valve, a filter, a one-way valve, a pressure reducing valve and an air pressure sensor, the check valve, the filter, the one-way valve and the pressure reducing valve are connected in series on the air supply pipeline, the one-way valve is used to limit the one-way flow of pressurized gas, the air pressure sensor is arranged in the water tank, and the air pressure sensor, the check valve and the air compression pump are all connected to the central controller signal.

[0090] The air pressure sensor is used to detect the gas pressure value in the water tank; when the gas pressure value in the water tank is lower than the set value, the air pressure sensor transmits a digital signal to the central controller, and the central controller issues an instruction to the air compression pump to work, and the connection inlet connected to the air compression pump is opened, and the air compression pump works to pressurize the water tank; when the gas pressure value in the water tank is higher than the set value, the air pressure sensor transmits a digital signal to the central controller, and the central controller issues an instruction to the air compression pump to stop working, and the connection inlet connected to the air compression pump is closed.

[0091] The pressure reducing valve is used to ensure that the gas pressure at the air inlet does not exceed its maximum operating pressure.

[0092] When the central controller detects that the variable frequency water pump connected to the water outlet of the water tank has failed, the air boosting mechanism can be used to temporarily replace the failed variable frequency water pump to pressurize the water in the water tank, thereby providing stable water supply to the concrete intelligent maintenance water equipment, providing time to arrange personnel for maintenance in a timely manner without affecting the maintenance of the concrete building, thereby ensuring the sustainability of the system.

[0093] Optionally, in a possible implementation, the water level sensor includes a float water level sensor, a pressure water level sensor, a capacitive water level sensor, an ultrasonic water level sensor, an optical water level sensor, a resistive water level sensor, a magnetic float water level sensor or a thermistor water level sensor.

[0094] Optionally, in a possible implementation, the pressure sensor includes a strain gauge pressure sensor, a piezoresistive pressure sensor, a capacitive pressure sensor, a piezoelectric pressure sensor, a vibration frequency pressure sensor, a photoelectric pressure sensor, an optical fiber pressure sensor or an ultrasonic pressure sensor.

[0095] Optionally, in a possible implementation, the altitude sensor includes a barometric altitude sensor, an ultrasonic sensor, or a laser ranging sensor.

[0096] In order to keep the water storage amount in the water tank stable and not affect the water supply, the volume capacity of the water tank is L5, and the volume capacity values ​​corresponding to the upper and lower limit water levels detected by the water level sensor are L2 and L4 respectively. The required water volume capacity value in the water tank is set to L4, among which L1<L2<L3<L4<L5.

[0097] When the water level in the water tank is low and its corresponding volume capacity value is less than L2, for example, when it is L1, the water level sensor detects that the water level is too low, and the feedback digital signal is transmitted to the central controller. The central controller controls the water pump to work through the Ethernet communication line to transfer water to the water tank, the solenoid valve opens, and the water level in the water tank gradually rises. When the volume capacity value corresponding to the water level reaches L4, the feedback digital signal is transmitted to the central controller at the same time. The central controller controls the water pump to stop working through the Ethernet communication line and stop transferring water to the water tank, and the solenoid valve closes, so that the volume capacity value corresponding to the water level in the water tank can be maintained at the required water volume capacity value L4.

[0098] When the variable frequency water pump connected to the water outlet of the water tank fails, in order to ensure that the concrete intelligent curing water equipment can supply water stably, the total gas pressure is in the range of P1 to P10, the pressurized gas pressure in the water tank is in the range of P3 to P7, the air pressure sensor on the water tank detects the upper and lower pressure values ​​of P2 and P6 respectively, the air compression pump output gas pressure is P3 to P7, and the opening pressure of the pressure reducing valve of the air regulating component is P8 to P9, among which P1<P2<P3<P4<P5<P6<P7<P8<P9<P10.

[0099] When the gas pressure is low, less than P2, for example, P1, the gas does not perform pressure regulation when passing through the air conditioning component, and enters the water tank after filtering. Finally, the left and right sides of the one-way valve reach a balance, and the pressure in the water tank is P1. At this time, the air pressure sensor on the water tank detects that the pressure value is too low, and the feedback digital signal is transmitted to the central controller; the central controller simultaneously analyzes the digital signals transmitted by the air pressure sensor on the water tank and the height sensor connected to the concrete intelligent curing water equipment, and controls the air compression pump to start working through the Ethernet communication line to pressurize the water tank according to the real-time pressure value in the water tank and the water supply pressure value required by the concrete intelligent curing water equipment calculated by the built-in water supply pressure variable algorithm module of the central controller. The supplementary pressurized gas provided by the pressurization operation enters the water tank after passing through the air conditioning component, and the pressure in the water tank gradually increases. When the pressure reaches P6, the feedback digital signal is transmitted to the central controller at the same time, and the central controller controls the air compression pump to stop working through the Ethernet communication line and not to pressurize the water tank, so that the gas pressure in the water tank can be maintained within the range of P3 to P7.

[0100] When the gas pressure is relatively large, greater than P7, for example, P10, the gas is pressure-regulated when passing through the air conditioning component. After pressure regulation, the output gas pressure is P3~P7. After filtration, it enters the water tank. Finally, the left and right sides of the one-way valve reach a balance, and the pressure in the water tank is P3~P7. At this time, the air compression pump does not need to work.

[0101] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
