At the outer end of the cutting blade 1062, during the use of the forward cooling nozzle, when cooling water passes through the cooling nozzle, the water flow will impact the cutting blade 1062. Since the cutting blade 1062 has a certain curvature, the water flow will drive the cutting blade 1062 to rotate, thereby using the cutting blade 1062 to break up large impurities in the water, making it easier for the impurities to be ejected through the cooling nozzle 102, thereby avoiding clogging of the cooling nozzle 102. When the cutting blade 1062 rotates, a cleaning brush 1063 is installed at the end of the blade, which can clean the scale attached to the inner wall of the nozzle.

[0026] The connecting mechanism 2 includes a connecting flange 201, a screw hole 202, a bolt washer 203, a fixing bolt 204 and a sealing waterproof gasket 205. The connecting flange 201 is fixedly installed on the left end of the cylinder 101, the screw hole 202 is fixedly arranged on the right end of the connecting flange 201, the bolt washer 203 is movably connected to the right end of the screw hole 202, the fixing bolt 204 is movably connected to the right end of the bolt washer 203, and the sealing waterproof gasket 205 is fixedly installed on the left end of the connecting flange 201. During installation, the connecting flange 201 and the connecting flange on the water tank are aligned, and the fixing bolt 204 is passed through the bolt washer 203 and the screw hole 202 and tightened, so as to fix the forward cooling nozzle. The setting of the sealing waterproof gasket 205 can improve the sealing effect and prevent water leakage when the forward cooling nozzle is in use.

[0027] Working principle: during installation, align the connecting flange 201 with the connecting flange on the water tank, and pass the fixing bolt 204 through the bolt washer 203 and the screw hole 202 and tighten it to fix the forward cooling nozzle. The setting of the sealing waterproof pad 205 can improve the sealing effect and avoid water leakage when the forward cooling nozzle is in use. During the use of the forward cooling nozzle, when the cooling water passes through the cooling nozzle, the water flow will impact the cutting blade 1062. Since the cutting blade 1062 has a certain curvature, the cutting blade 1062 will be driven to rotate when the water flow impacts, so that the cutting blade 1062 can be used to cut large impurities in the water into pieces, making it easier for the impurities to be ejected through the cooling nozzle 102, thereby avoiding clogging of the cooling nozzle 102. When the cutting blade 1062 rotates, a cleaning brush 1063 is installed at the end of the blade to clean the scale attached to the inner wall of the nozzle.
