Summary of the Utility Model

[0030] A limiting rod 204 penetrates through the side of the threaded block 203. One end of the limiting rod 204 is fixedly connected to the inner wall of the chiller 101. Heat dissipation holes 104 are opened on the front and side surfaces of the chiller 101. This design can accurately measure the temperatures at different positions inside the chiller 101 and provide an accurate temperature limit detection function.

[0031] The inner wall of the chiller 101 is fixedly connected with a hydraulic cylinder 208. One end of the hydraulic cylinder 208 is slidably connected with a force rod 209 through a piston, and the other end of the hydraulic cylinder 208 is slidably connected with a hydraulic rod 212 through a piston. One end of the hydraulic rod 212 is fixedly connected with a rack 213, and one end of the force rod 209 is fixedly connected with a force plate 211. The inner wall of the chiller 101 is rotatably connected with a rotating rod 214. The circumferential surface of the rotating rod 214 is fixedly connected with a gear 215, and the circumferential surface of the rotating rod 214 is fixedly connected with an extrusion rod 216.

The initial state of the spring 210 is a relaxed state, which not only improves the operation efficiency but also reduces human error, ensuring the reliability and continuity of temperature detection.

[0033] The shape of the hydraulic cylinder 208 is set to C-shaped. The side surface of the rack 213 meshes with the side surface of the gear 215, reducing the risk of failures caused by mechanical wear or poor transmission, and lowering the maintenance cost and downtime.

[0034] The force plate 211 is located on the movement trajectory of the threaded block 203, and the temperature sensor 207 is located on the movement trajectory of the extrusion rod 216, enabling a comprehensive understanding of the temperature distribution of the entire chiller 101 and ensuring that the temperature of each part is within the safe range.

The displacement of the fixed plate 206 drives the temperature sensor 207 to displace in the horizontal direction, achieving the function of detecting the internal temperature of the chiller 101. When the temperature sensor 207 displaces to the rightmost side, the threaded block 203 further displaces to squeeze the force-bearing plate 211, causing the force-bearing plate 211 to squeeze the force-bearing rod 209, making the force-bearing rod 209 displace inward to squeeze the piston inside the hydraulic cylinder 208. The piston inside the hydraulic cylinder 208 pushes the liquid inside it. The liquid inside the hydraulic cylinder 208 pushes another piston to displace. The piston pushes the hydraulic rod 212 to displace. The displacement of the hydraulic rod 212 drives the rack 213 to displace. Then, the displacement of the rack 213 drives the gear 215 to rotate. The rotation of the gear 215 drives the rotating rod 214 to rotate. Then, the rotation of the rotating rod 214 drives the extrusion rod 216 to rotate. The extrusion rod 216 will push the temperature sensor 207 to drive the turntable 205 to rotate, achieving the function of automatically flipping the angle of the temperature sensor 207 after detection and detecting the top of the chiller 101 again.
