[0002] The cooling tower sump, also known as a water collection pan or bottom pool, is an important component of the cooling tower. Its main function is to collect the return water from the circulating cooling water system, and it also has the function of regulating the water volume of the system. The sump is usually located at the bottom of the cooling tower and is used to collect water droplets falling from the packing material and overflow water from the cooling water system.
[0003] For example, patent CN215114048U discloses a cooling tower water collection pan antifreeze device, which includes a base plate, a support frame, a water collection pan, water pipes, a piston mechanism, and a water storage mechanism. The support frame is located on one side of the bottom of the base plate, the water collection pan is located on top of the support frame, a water pipe is located on the lower part of one side of the water collection pan, the piston mechanism is located in the middle of one side of the bottom of the base plate, and the water storage mechanism is located on one side of the bottom of the base plate. However, this device cannot perform real-time temperature monitoring of the cooling tower water collection pan; it can only continuously activate the piston mechanism, resulting in an insignificant antifreeze effect and a risk of the water in the collection pan bursting due to freezing and expansion.
[0004] Therefore, in order to solve this problem, we propose a cooling tower water collection pan antifreeze device. Utility Model Content

A first rack is fixedly connected to one side, and a movable shaft is movably connected inside the upright plate. A meshing component is fixedly connected to the movable shaft and meshes with the first rack. A frame is fixedly connected to the outer wall of one side of the upright plate. A third sliding groove is opened on the inner walls of both sides of the frame. A U-shaped mounting plate is fixedly connected to the top of the frame. A wind baffle is movably connected inside the U-shaped mounting plate. A third slider is fixedly connected to one end of the wind baffle and slides in one of the third sliding grooves. A second rack is fixedly connected to the other end of the wind baffle and meshes with the meshing component. The second rack slides in the other third sliding groove.

[0012] This utility model has the following beneficial effects:
[0013] In this invention, a temperature detection ring is used to monitor the temperature of the water collection device in real time. When the temperature of the water collection device is low, the meshing of the first and second racks with the meshing parts adjusts the amount of hot air blown by the hot air fan onto the water collection device, ensuring that the temperature of the water collection device is kept constant in real time. This prevents the water collection device from freezing and avoids the problem of not being able to monitor the temperature of the cooling tower water collection pan in real time, having to continuously start the piston structure, resulting in ineffective antifreeze and the water in the collection pan easily bursting due to the expansion of the frozen water. A dustproof plate is also provided to protect the hot air fan from dust. The structure is simple and easy to operate. Attached Figure Description
