Description

Technical Field

[0001] This utility model relates to the field of cooling tower cooling systems, and in particular to a water turbine cooling tower fan. Background Technology

[0002] A water turbine is a rotary power machine that converts the kinetic or potential energy of water flow into mechanical energy. It is primarily used in hydroelectric power plants to drive generators to produce electricity. Its core principle is to drive the runner to rotate through the impact of water flow on the blades (such as in reaction turbines) or high-speed jetting (such as in impulse turbines), thereby outputting shaft power. Based on the mode of water flow action, they can be classified into mixed-flow, axial-flow, and through-flow types. They are characterized by high efficiency (up to 90% or more), clean and renewable operation, and strong peak-shaving capabilities, making them core equipment in modern hydroelectric systems.

[0003] While existing technologies can achieve some water cooling, they suffer from drawbacks. The poor cooling effect of existing turbine cooling tower fans reduces the cooling efficiency of the water before it enters the turbine, requiring more time for heat dissipation and impacting the overall power generation performance. Therefore, we propose a turbine cooling tower fan that solves these problems. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a water turbine cooling tower fan.

[0005] The technical solution of this utility model is as follows: A water turbine cooling tower fan includes a housing, a rotating block, fan blades, a mounting base, and baffles. The housing has an upper opening at its upper end, and a mounting frame is fixed to the inner wall of the upper opening. A rotating block is rotatably mounted on the upper end of the mounting frame. An angle-adjustable fan blade is provided on the outer wall of the rotating block. A fixing frame is fixed to the lower end of the mounting frame, and a limiting rod is provided at the lower end of the fixing frame. A threaded column is fixed to the surface of the limiting rod. A mounting base is provided inside the housing, and a retainer is fixed inside the mounting base. The retainer is threadedly connected to the threaded column. Blowers are arranged in a ring array on the surface of the retainer. Heat dissipation grooves are arranged in a ring array on the outer wall of the housing. Baffles are arranged in a ring array on the outer wall of the housing.

[0006] When in use, this device introduces water to be cooled into the tank via the inlet pipe. As the water level rises, the mounting base experiences upward buoyancy due to the float, which, in conjunction with the threaded column, allows the mounting base to rotate upwards. Multiple angles on the mounting base surface, controlled by a blower operated by motor two, rapidly dissipate heat from the water surface upwards at a specific angle. This, combined with the rotating block and fan blades driven by motor three inside the opening, achieves highly efficient overall cooling. If the cooling capacity is insufficient, a roller driven by motor one rotates, causing the connecting ring on the outer wall of the tank to move, opening the baffle cooling slots for even more efficient cooling. This device features a highly efficient cooling fan design, combined with innovative tank structure, to achieve highly efficient overall cooling, making it highly practical.

[0007] Preferably, the baffles are fixed together by a connecting ring, which is slidably connected to the outer wall of the housing. The annular sliding connection structure ensures that multiple baffles move synchronously, avoiding single-point failures from affecting overall heat dissipation. Combined with the curved surface of the housing, it optimizes airflow and reduces airflow resistance loss.

[0008] Preferably, the baffle surface has an installation groove, a motor is fixed inside the installation groove, a roller is rotatably installed on one side of the outer wall of the baffle, the roller is in contact with the surface of the housing, the output shaft of the motor is fixedly connected to the rotation center of one side of the roller, the surface of the roller is made of rubber, and the contact surface with the housing has high frictional adhesion, realizing silent operation and zero-backlash transmission. The motor can drive the connecting frame to rotate stably at a certain angle to open the heat dissipation slot.

[0009] Preferably, the outer wall of the rotating block is provided with multiple arc-shaped array of limiting holes, and the outer wall of the rotating block is provided with fan blades. One end of one side of the fan blade is fixed to the outer wall of one side of the rotating block with screws, and the other end of one side of the fan blade is threadedly connected to one of the limiting holes with screws. The angle adjustment of the eight hole positions, combined with the arc-shaped limiting structure, allows the angle of attack of the fan blades to be precisely adjusted within a certain angle range.

[0010] Preferably, a base is fixed at the lower end of the box, an inlet is provided at the lower end of one side of the box, and an outlet is provided on the side of the inlet. The three-point anti-vibration base, together with the rubber shock-absorbing pad, can increase the stability of the device. Both the inlet and outlet are connected to an external pump to realize the supply and output of water.

[0011] Preferably, a motor is fixed at the lower end of the mounting bracket, and the output shaft of the motor is fixedly connected to the rotation center at the lower end of the rotating block. The motor can drive the rotating block to rotate the fan blades, thereby achieving overall heat dissipation.

[0012] Preferably, a float is fixed at the lower end of the mounting base, and two generators are symmetrically designed at the upper end of the retainer. The float ensures that the mounting base is above the water surface and will not sink below the water surface. The dual generator system can supply power to the second motor and the blower. The generator on each side is electrically connected to the blower group on one side, which can prevent the wire harness from getting tangled with the threaded post and affecting the rotation effect.

[0013] Preferably, the outer wall of the mounting base is provided with a second mounting groove, and a second motor is fixed inside the second mounting groove. The output shaft of the second motor is fixedly connected to the rotation center on one side of the blower. The second motor is electrically connected to the generator. The second motor can drive the blower to rotate at a certain angle to achieve rapid dissipation of hot airflow inside the housing.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] I. This utility model constructs a three-dimensional heat dissipation network through a three-level linkage heat dissipation system (blower + angle-adjustable fan blades + adjustable baffle), and combined with buoyancy adaptive adjustment, it achieves a dual breakthrough in heat dissipation efficiency and energy utilization.

[0016] Second, based on the first beneficial effect, the power for the second motor and the blower comes from the generator inside the housing, which can prevent the wire harness from getting tangled with the threaded post and affecting the upward rotation of the mounting base. Furthermore, the upward rotation allows the blower to distribute the heat from the water surface more evenly, and together with the adjustment of the opening of the heat dissipation slot, it can achieve more efficient heat dissipation.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
