Description

Technical Field

[0001] The utility model relates to the technical field of closed cooling towers, in particular to a new type power connection protection device for a closed cooling tower integrated machine. Background Art

[0002] A closed cooling tower system consists of a main unit, water tank, circulating water pump, and electrical control cabinet. The main unit comprises a housing, heat exchanger, fan, spray water pump, water collector, water tank, and piping valves. During operation, the cooling medium (soft water, oil, or other liquid) is driven by the main circulation pump to circulate between the heat exchanger and the equipment to be cooled. Spray water is evenly applied to the heat exchanger, forming a uniform film on its outer surface. Cold air enters the tower through the air inlet below the tower body and flows countercurrently with the spray water across the heat exchanger surface. This process involves two heat transfer mechanisms: heat conduction between the cold air and the cooling medium, and heat absorption by the evaporation of the spray water. The saturated hot and humid air, which has absorbed heat, is discharged into the atmosphere by the fan. The remaining spray water flows into the water tank below the tower body and is then pumped to the spray system. This cycle continues, cooling the cooling medium within the heat exchanger. Closed cooling towers have two operating modes: air cooling and air cooling + spraying. Switching between the two modes is automatically controlled by the electronic control system based on operating conditions, achieving energy savings and consumption reduction. Existing new power connection protection devices for integrated closed cooling towers have fixed power connections, making them difficult to remove and install when replacement is required. To address this issue, a new power connection protection device for integrated closed cooling towers is proposed.

[0003] The application number is 202121498793.6, which discloses a novel overload protection device for a drop mixer reducer, and relates to the technical field of reducer overload protection. The utility model includes a mixer and a reducer that drives the mixer, one end of the reducer is fixedly connected to a rotating shaft, and the rotating shaft is connected to an output gear through an overload protection mechanism. The top of the reducer is fixedly connected to a mounting seat, and the mounting seat is fixedly connected to a detection mechanism. The overload protection mechanism includes an electrically controlled telescopic rod, and the detection mechanism includes a laser transmitter, a partition and a laser receiver. The utility model is a novel overload protection device for a drop mixer reducer. Through the detection mechanism and the overload protection mechanism, when the reducer is detected to be overloaded, the electrically controlled telescopic rod is controlled to retract into the inside of the mounting slot, thereby separating the rotating shaft from the output gear, thereby avoiding the problem of reduced service life of the reducer due to overload.

[0004] However, there are some shortcomings. The device is equipped with a detection mechanism and an overload protection mechanism. When it detects that the reducer is overloaded, the electric telescopic rod is controlled to retract into the inside of the installation slot, thereby separating the rotating shaft and the output gear, thereby avoiding the problem of the reducer's service life being reduced due to overload. However, the device has a fixed power connection. When the power connection needs to be replaced, it is difficult to disassemble and assemble, and is not suitable for the new power connection protection used in closed cooling tower integrated machines. Utility Model Content

[0005] The purpose of the present utility model is to provide a new type of power connection protection device for a closed cooling tower integrated machine, so as to solve the problem proposed in the above background technology that the device is provided with a detection mechanism and an overload protection mechanism.
