[0031] Please refer to Figures 1-2 , an embodiment of the present utility model provides an intelligent control cabinet for a variable - flow cooling water pump, including a cabinet 1, a flow adjustment unit, a display unit, a heat dissipation unit, and an alarm unit; wherein,

[0032] The flow adjustment unit includes a controller 2, a frequency converter 3, a water pump 4, a flow sensor 8, and a flow meter 9 disposed inside the cabinet 1, and is used for monitoring and adjusting the size of the water outlet flow of the water pump 4;

[0033] An inlet electromagnetic valve 7 is installed on the inlet pipeline of the water pump 4, and an outlet electromagnetic valve 6 and a pressure sensor 5 are successively installed on the outlet pipeline;

[0034] Among them, the controller 2 is electrically connected to the frequency converter 3, and the frequency converter 3 is respectively electrically connected to the water pump 4 and the pressure sensor 5;

[0035] Among them, the frequency converter 3 is electrically connected to the water pump 4 to realize the variable - frequency adjustment of the rotation speed of the water pump 4, and further realize the adjustment and control of the water outlet flow of the water pump 4;

[0036] The connection and working principle between the frequency converter 3 and the water pump 4 are as follows: First, a pressure sensor 5 is installed at the water outlet of the water pump 4 to measure the water supply pressure in real time; then the pressure sensor 5 is connected to the frequency converter 3 so that it can receive real-time pressure signals; next, according to the actual requirements and the pressure measurement results, the pressure set value is gradually adjusted to keep the water supply pressure within the set range; through such a control method, the frequency converter 3 can adjust the speed of the water pump 4 according to the feedback signal of the pressure sensor 5, so as to maintain the constant pressure state of the water supply system, and further, the purpose of adjusting the flow rate can be achieved by adjusting the speed of the water pump 4 and the pressure of the water pump 4.

[0037] There are two groups of flow sensors 8 and flow meters 9, which are respectively installed on the inlet pipe and the outlet pipe of the water pump 4 in sequence; that is, a flow sensor 8 and a flow meter 9 are sequentially arranged on the inlet pipe of the water pump 4 to monitor the magnitude of the water flow entering the water pump 4; a group of flow sensors 8 and flow meters 9 are also sequentially arranged on the outlet pipe of the water pump 4 to monitor the magnitude of the water flow coming out of the water pump 4.

[0038] Through the two groups of flow sensors 8 and flow meters 9, first, the flow rates of the water inlet and outlet of the water pump 4 can be monitored, and second, when a failure occurs, the range of the failure point can be assisted to be found through the process of monitoring the flow rate, improving the efficiency of fault repair.

[0039] The display unit includes a display screen 10 arranged on the door panel of the cabinet 1, which is used to display relevant data and adjust parameters;

[0040] The heat dissipation unit is arranged inside the cabinet 1 and is used to dissipate heat from the environment inside the cabinet 1;

[0041] In a preferred embodiment, the heat dissipation unit includes a temperature sensor, a heat dissipation fan and a strip-shaped heat dissipation hole 12; among them,

[0042] The temperature sensor is fixedly arranged inside the cabinet 1 and is used to monitor the ambient temperature inside the cabinet 1;

[0043] The heat dissipation fan is fixedly arranged on the top surface inside the cabinet 1 and is used to accelerate the air circulation inside the cabinet 1;

[0044] The strip-shaped heat dissipation hole 12 is arranged on the door panel of the cabinet 1 and is used to realize the exchange and circulation of the gas inside and outside the cabinet 1; among them, a protective net cover is arranged on the inner side of the door panel of the cabinet 1 corresponding to the strip-shaped heat dissipation hole 12 to prevent foreign objects from entering the inside of the cabinet 1.

[0045] Specifically, when the temperature sensor monitors that the ambient temperature inside the cabinet 1 is higher than the set threshold value, the heat dissipation fan can be started through the controller 2 to accelerate the exchange of air inside and outside the cabinet 1 and improve the heat dissipation efficiency.

[0046] An alarm unit is provided on the cabinet 1 and is used to give an alarm when a malfunction occurs during operation.

[0047] Among them, the alarm unit includes an alarm fixed on the cabinet 1, such as the buzzer 11, which is used to warn the staff when a malfunction occurs in the equipment operation.

[0048] In a preferred embodiment, the flow sensor 8, the flow meter 9, the inlet solenoid valve 7, the outlet solenoid valve 6, the display screen 10, the buzzer 11, the cooling fan, and the temperature sensor are all electrically connected to the controller 2.

[0049] The working principle of the present utility model:

[0050] When adjusting the flow rate of the water pump 4, the speed of the water pump 4 is adjusted through the frequency converter 3. Specifically, the frequency converter 3 adjusts the speed of the motor by changing the frequency of the working power supply of the motor, thereby controlling the flow rate and pressure of the water pump 4; when the system water pressure is lower than the set value, the frequency converter 3 will automatically increase the speed of the motor, so that the flow rate and pressure of the water pump 4 increase to meet the demand; when the water pressure is higher than the set value, the frequency converter 3 will reduce the speed of the motor, so that the flow rate and pressure of the water pump 4 decrease.

[0051] In addition, the method of frequency conversion adjustment of the water pump speed has higher efficiency and economy compared with other adjustment methods (such as throttle adjustment and reflux adjustment); the variable speed adjustment method realizes the adjustment of the flow rate and pressure by changing the speed of the prime mover of the water pump, and the efficiency change of the water pump is small, and it can maintain a high operating efficiency within a large range.

[0052] When a malfunction occurs in the frequency converter 3, the opening degrees of the inlet solenoid valve 7 and the outlet solenoid valve 6 can be temporarily adjusted through the controller 2, and then the outlet flow rate of the water pump 4 can be controlled, so that the entire system where it is located can continue to operate.

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to the specific circumstances.
