Description

Technical Field

[0001] The invention relates to the technical field of hydropower stations, in particular to a remote automatic temperature control device for a hydropower station. Background Art

[0002] In some areas with cold winters, the temperature may drop to around 30°C. General equipment can hardly operate normally in such an environment. Therefore, in order to ensure the normal operation of the equipment, it is usually necessary to use electric heating devices to ensure that the temperature of the operating environment is not too low. After the winter, when the temperature rises, the electric heating equipment needs to be turned off to prevent the temperature from being too high or causing waste of resources.

[0003] However, dams, surge tank control rooms and other places are generally built far away from the power station, and personnel are often required to go to the site to start and stop the electric heating equipment, which is not only labor-intensive, but also dangerous in winter due to ice and snow, affecting personnel safety;

[0004] In addition, the manual on-site start-up and shutdown method is greatly affected by human factors, and the time of putting the electric heating device into and out of operation cannot be accurately controlled, which often leads to delays.

[0005] Moreover, the temperature of the electric heating device cannot be adjusted according to the indoor temperature, and the temperature cannot be adjusted effectively in real time, resulting in the indoor temperature being often too high or too low. Summary of the invention

[0006] The purpose of the present invention is to provide a remote automatic temperature control device for a hydropower station. The present invention has the advantage of being able to realize the switch control of the equipment without the need for manual operation on site.

[0007] The technical solution of the present invention is: a remote automatic temperature control device for a hydropower station, comprising a temperature sensing unit, a control unit and an electric heating device; the control unit is respectively connected to the temperature sensing unit and the control unit; the temperature sensing unit and the electric heating device are correspondingly arranged, and the electric heating device is located at an equipment location far away from the main machine room of the hydropower station.

[0008] In the aforementioned remote automatic temperature control device for a hydropower station, the temperature sensing unit includes a plurality of temperature sensors for sensing temperature distributed at different locations in the same place.

[0009] In the aforementioned remote automatic temperature control device for a hydropower station, the electric heating device includes a heating device for heating.

[0010] In the aforementioned remote automatic temperature control device for a hydropower station, the control unit is provided with a control system for controlling the opening and closing of the electric heating device; it also includes video surveillance equipment and danger alarm devices installed at the corresponding site; the video surveillance equipment and danger alarm devices are both connected to the control unit; the main engine room of the hydropower station is provided with control equipment connected to the control unit and matching display operation equipment.

[0011] Compared with the prior art, the present application sets a temperature sensing unit in a remote place far away from the main engine room of the hydropower station, sets a control unit connected to the temperature sensing unit in the main engine room, connects the electric heating device originally set in the remote place with the control unit, so that the ambient temperature of the place is sensed in real time by the temperature sensing unit, and the control unit remotely controls the start and stop and power adjustment of the electric heating device according to the comparison between the received real-time temperature and the manually set preset temperature, without the need for manual risk to start and stop the equipment on site;

[0012] Through the coordinated work of temperature sensing and control unit, real-time monitoring and precise control of temperature are achieved, which improves the automation level of the equipment.

[0013] The control unit can adjust the heating power according to the difference between the real-time temperature and the preset temperature, thus avoiding unnecessary energy waste and improving energy utilization efficiency.

[0014] Therefore, the present invention has the advantage of being able to implement device switch regulation without the need for manual on-site operation. BRIEF DESCRIPTION OF THE DRAWINGS
