Description

Technical Field

[0001] The present invention relates to the technical field of electrical equipment, and specifically to an intelligent cooling system applied to the electrical cabinet of a gantry machine tool. Background Art

[0002] A gantry machine tool is a numerically controlled machine tool with high precision, high efficiency, and multiple functions. The structure of a gantry machine tool is similar to that of a gantry crane, mainly consisting of a gantry, a crossbeam, a lower spindle, a workbench, a tool magazine, and a numerical control system, etc. The characteristics of this machine tool include the ability to perform large-size machining, strong load-bearing capacity, high machining accuracy, and the ability to complete machining tasks by moving components such as the machining head and the workbench while keeping the workpiece in a fixed position. The servo drivers, I / O modules, and other electronic devices in the electrical cabinet of a gantry machine tool require a relatively low working environment temperature. When the temperature is too high, it will affect the operation of the servo drivers, I / O modules, and other electronic devices, resulting in damage to the machine tool and scrapping of the workpiece.

[0003] The traditional cooling system of the electrical cabinet of a gantry machine tool is uncontrolled and starts with the startup of the gantry machine tool. Especially when the gantry machine tool is in the north and in a non-constant temperature environment, when the working environment temperature is very low, the cooling system in the electrical cabinet of the gantry machine tool will still start. When the cooling system continues to work in an environment where excessive cooling is not required, it is easy to waste resources, increase the usage frequency of the cooling system, increase the usage cost, and shorten the service life.

[0007] A display screen is installed on the single-chip microcomputer, and the output end of the single-chip microcomputer is electrically connected to the display screen. The display screen is used to display the temperature inside the electrical cabinet body in real time;

[0008] A temperature sensor is provided inside the electrical cabinet body. The temperature sensor is communicatively connected to the input end of the single-chip microcomputer.

[0009] Inside the inner wall of the electrical cabinet, there are a first relay and a second relay. A fan and a cooling device are installed inside the electrical cabinet. The output end of the single-chip microcomputer is electrically connected to one end of the first relay and one end of the second relay respectively. The other end of the first relay is electrically connected to the fan. The first relay is used to control the on / off of the fan. The other end of the second relay is electrically connected to the cooling device. The second relay is used to control the on / off of the cooling device.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0024] Please refer to Figure 1-2 , an intelligent cooling system applied to the electrical cabinet of a gantry machine tool, including an electrical cabinet body 9, and a single-chip microcomputer 2 is provided outside the electrical cabinet body 9, and the single-chip microcomputer 2 is used to control the operation of the intelligent cooling system;

[0025] A display screen 3 is installed on the single-chip microcomputer 2, and the output end of the single-chip microcomputer 2 is electrically connected to the display screen 3. The display screen 3 is used to display the temperature inside the electrical cabinet body 9 in real time, which is convenient for people to watch it in real time, convenient for subsequent use, and ensures safety.

[0026] A temperature sensor 1 is provided inside the electrical cabinet body 9. The temperature sensor 1 is communicatively connected to the input end of the single-chip microcomputer 2. The temperature sensor 1 is used to measure and monitor the temperature inside the electrical cabinet body 9 in real time, and transmit the measured temperature data to the single-chip microcomputer 2 in time, which is convenient for the subsequent display of the display screen 3 and the control work of the single-chip microcomputer 2, ensures safety, and is convenient for the use of the device.

[0027] Multiple groups of temperature sensors 1 are provided. Through the multiple groups of temperature sensors 1, it is convenient to measure the temperature at various positions inside the electrical cabinet body 9, ensure the accuracy of the measured data, avoid the contingency of data measurement, and increase safety.

[0028] The microcontroller 2 is equipped with a data processing unit. The data processing unit 2 processes the temperature data measured by multiple temperature sensors 1 according to the trimmed mean, that is, the average of the measured temperatures calculated after removing one highest value and one lowest value, and then displays it on the display screen 3 later, avoiding large measurement errors caused by malfunctions of individual temperature sensors 1, increasing safety, and facilitating the use of the device.

[0029] The inner wall of the electrical cabinet body 9 is provided with a first relay 4 and a second relay 5. A fan 6 and a cooling device 7 are installed in the electrical cabinet body 9. The output end of the microcontroller 2 is electrically connected to one end of the first relay 4 and one end of the second relay 5 respectively. The other end of the first relay 4 is electrically connected to the fan 6, and the other end of the second relay 5 is electrically connected to the cooling device 7. The cooling device 7 can be an air conditioner, which refrigerates through a compressor to ensure the safety of electrical work. The microcontroller 2 is preset with a first-level low temperature and a second-level low temperature, and the first-level low temperature is greater than the second-level low temperature; the second-level low temperature is less than or equal to the lowest rated operating temperature of the electrical components;

[0030] When the temperature sensor 1 measures that the temperature inside the electrical cabinet is higher than the first-level low temperature, at this time, the microcontroller 2 controls the fan 6 and the cooling device 7 to start simultaneously through the first relay 4 and the second relay 5, ensuring the maximum cooling speed inside the electrical cabinet body 9, improving the heat dissipation effect and efficiency inside the electrical cabinet body 9, ensuring a suitable working temperature environment for the electrical cabinet body 9, facilitating the operation of electronic devices such as servo drivers and I / O modules, avoiding the influence of high temperature on them, slowing down the aging speed of electrical components, and increasing the service life of electrical components.

[0031] When the temperature sensor 1 measures that the temperature inside the electrical cabinet is lower than the first-level low temperature and higher than the second-level low temperature, at this time, the microcontroller 2 only starts the fan 6 through the first relay 4 to perform air-cooling on the inside of the electrical cabinet, ensuring appropriate cooling efficiency and effect, appropriately reducing the temperature inside the electrical cabinet body 9, enabling the electrical components to still work in a suitable temperature environment, facilitating ensuring the normal service life of the electrical components, and increasing safety.

[0032] When the temperature sensor 1 measures that the temperature inside the electrical cabinet is lower than the second-level low temperature, at this time, the microcontroller 2 controls the fan 6 and the cooling device 7 to be turned off through the first relay 4 and the second relay 5. At this time, the temperature in the electrical cabinet body 9 is at the lowest rated operating temperature of the electrical equipment, and there is no need to cool the inside of the electrical cabinet anymore, effectively reducing the waste of electric energy, reducing the working duration of the fan 6 and the cooling device 7, effectively increasing the service life of the components, which is equivalent to increasing the service life of the device and reducing the use cost.

[0033] The side wall of the electrical cabinet body 9 is provided with a filter net 8, and the filter net 8 is used to filter the intake air, improve the cleanliness inside the electrical cabinet body 9, reduce the influence of external dust, etc. on the inside of the device, increase safety, and facilitate the use of the device.

[0034] The present invention combines the northern climate and the actual working environment of the gantry, and performs refined hierarchical control on the conventional cooling device according to the temperature. It can not only effectively meet the cooling requirements of the electrical cabinet, but also effectively reduce the waste of electric energy. When the working environment temperature is very low, the temperature inside the electrical cabinet will also become very low. At this time, only a small-power fan air cooling needs to be started. When the ambient temperature is even lower, the temperature inside the electrical cabinet also becomes lower. At this time, any cooling device including air cooling does not need to be started to save energy.
