Description

Technical Field

[0001] This invention relates to the field of motor technology, specifically a high-efficiency motor for cooling towers. Background Technology

[0002] A cooling tower is an evaporative cooling device that uses water as a circulating coolant to absorb heat from a system and release it into the atmosphere in order to lower the water temperature. It requires a special motor and fan to blow water vapor and heat out of the tower.

[0003] According to Chinese Patent Publication No. CN221151086U, this invention relates to the field of cooling tower motor technology, specifically a dedicated cooling tower motor, comprising: a main body including a housing, with a mounting plate and a first rotating shaft fixedly connected to the surface of the housing, a wiring compartment fixedly connected to the side of the housing, a second rotating shaft provided on the outer surface of the first rotating shaft, and a power cord fixedly connected to the surface of the wiring compartment; and a sealing mechanism including a threaded sleeve. This invention, by installing a bend on the surface of the power cord, avoids excessive bending of the power cord, reducing damage to the power cord surface. Furthermore, the rotation between the rotating block, the limiting ring, and the rotating groove allows for multi-angle adjustment of the bend. Under the action of the sealing strip, the end of the bend is sealed. Under the action of the connecting spring, the surfaces of the limiting ring and the rotating groove abut against each other, sealing the rotating groove. This achieves a seal at the connection between the power cord and the wiring compartment, preventing moisture from entering the wiring compartment and causing damage to the electrical components.

[0004] Currently, when using high-efficiency cooling tower motors, it is necessary to strengthen the protection of the internal sealing to prevent water vapor from entering, while also meeting the heat dissipation requirements. Positive pressure ventilation technology can effectively solve the water vapor problem and achieve the goal of long-term operation. Summary of the Invention

The support connecting frame and the upper end of the docking center seat are connected to the positive pressure ventilation structure. The first damping buffer seat, the second damping buffer seat, and the third damping buffer seat provide bearing at the center position. The spring damping rod provides bearing at the inclined position. The spring damping rod can extend and retract while also changing its angle, thereby improving the stable support performance of the docking center seat and achieving the purpose of side buffer protection.

[0014] Specifically, a first docking link is fixedly provided on the lower side of the docking center seat, a spring damping rod is hinged on the first docking link, the lower end of the spring damping rod is hinged to a second docking link, the side end of the second docking link is fixedly connected to the side fixing block, and the side fixing block is fixedly connected to the support bottom plate and the fixed side block.

The gas is then transported through the energy-saving motor and conducted to the second ventilation treatment component, where it is centrally guided and discharged. The supporting ring sleeve, supporting base block, fixing frame block, limiting sleeve block, support base frame, and side bracket are fixed as a whole, which facilitates the support of the energy-saving motor while providing limiting support for the first and second ventilation treatment components.

Then, it is guided by the control of the connecting valve pipe 15 to the inside of the guide ring sleeve 16. The gas is transmitted through the channel in the guide ring sleeve 16, so that the gas is introduced into the inside of the energy-saving motor 2 through the connecting sealed channel pipe 17 for heat dissipation treatment in the energy-saving motor 2.

The first ventilation treatment component 3 introduces gas. At this time, the ventilation pipe 11 in the first ventilation treatment component 3 transmits gas. The gas is conducted through the ventilation pipe 11 to the connecting pipe 12, and then guided through the guide pipe 13 to the connecting bend pipe 14. Then, it is guided by the connecting valve pipe 15 to the inside of the guide ring sleeve 16. It is transmitted through the channel in the guide ring sleeve 16, so that the gas is introduced into the inside of the energy-saving motor 2 through the connecting sealed channel pipe 17 for heat dissipation treatment. Then, it is guided and discharged through the second ventilation treatment component 10, thereby realizing continuous ventilation treatment and heat dissipation work in the energy-saving motor 2. At the same time, due to the positive pressure This also prevents external moisture from entering the interior of the energy-saving motor 2. Through the setting of the first ventilation treatment component 3 and the second ventilation treatment component 10, they are connected to the energy-saving motor 2, thereby actively controlling the airflow transmission and cooling the operation of the energy-saving motor 2.
