Two support frames 11 are fixedly connected to the middle of the inner wall of the box body 1 to support the filter plate 12. A filter plate 12 is arranged on the top of the support frame 11. A through groove 13 is provided on the right side of the box body 1 to facilitate the removal of the filter plate 12. Support plates 14 are fixedly connected to both sides of the top of the box body 1. Top plates 15 are fixedly connected to the adjacent sides of the tops of the two support plates 14 to play a supporting role. A water tank 16 is arranged on the left side of the top of the top plate 15. A water pump 17 is arranged on the right side of the water tank 16. The water tank 16 and the water pump 17 are connected by a connecting pipe. A hose 18 is fixedly connected to the right side of the water pump 17. The end of the hose 18 penetrates the top plate 15 and is fixedly connected with a shunt pipe 19. Spray heads 20 with uniform distribution are arranged at the bottom of the shunt pipe 19 to facilitate the spraying of water to cool the steel pipes below. Rotating rods 21 are fixedly connected to both ends of the shunt pipe 19 to play a connecting effect. A driving component is arranged outside the right support plate 14.

[0034] Refer to Figure 4 , The driving component includes a second motor 23. The second motor 23 is fixedly connected to the outside of the support plate 14. The output end of the second motor 23 is fixedly connected with a worm 24. A worm gear 22 is arranged outside the worm 24. The worm gear 22 is meshed and connected with the worm 24. The worm gear 22 is fixedly connected with the right rotating rod 21. The driving component can drive the worm gear 22 to rotate. The rotation of the worm gear 22 can drive the rotating rod 21 and the shunt pipe 19 to rotate, so as to adjust the angle of the spray heads 20 and enable the spray heads 20 to spray water evenly on the surface of the steel pipe from multiple angles.

[0035] Refer to Figure 1 , Figure 2 and Figure 3, through holes 2 are provided on both the front and rear sides of the box body 1. Through the through holes 2, it is convenient to put steel pipes into the box body 1. On the upper parts of the front and rear ends on the right side of the box body 1, first motors 6 are fixedly connected. The output ends of the first motors 6 penetrate through the box body 1 and are fixedly connected to the bidirectional threaded rods 5. By means of the first motors 6, it is convenient to drive the bidirectional threaded rods 5 to rotate. The arc-shaped blocks 10 are arranged in the telescopic grooves 8, and the outer parts of the arc-shaped blocks 10 are slidably connected to the inner walls of the telescopic grooves 8, which facilitates the arc-shaped blocks 10 to perform telescopic sliding in the telescopic grooves 8. The outer ends of both rotating rods 21 penetrate through and are rotatably connected to the support plates 14, which facilitates the rotating rods 21 to be rotatably connected to the support plates 14. A water pipe 25 penetrates through and is fixedly connected to the lower part on the left side of the box body 1, and the other end of the water pipe 25 penetrates through and is fixedly connected to the water tank 16. A pump body (not marked in the figure) is arranged outside the water pipe 25. By means of the pump body and the water pipe 25, the water in the box body 1 can be pumped out and enter the water tank 16 for recycling. The filter plate 12 penetrates through and is arranged in the through groove 13.

[0036] Working principle: When in use, the steel pipe is extended into the box body 1 through the through hole 2. Then, the first motor 6 is started to drive the bidirectional threaded rod 5 to rotate. By means of the bidirectional threaded rod 5, the two clamping plates 7 are driven to move relatively along the installation groove 4, thereby driving the two arc-shaped blocks 10 below to move relatively, clamping both sides of the two ends of the steel pipe to prevent loosening. And when the spring 9 is compressed, the spring 9 contracts, thereby driving the arc-shaped block 10 to contract in the telescopic groove 8 to prevent the clamping plate 7 from over-pressing and deforming the steel pipe. Then, the water pump 17 is started to pump out the water in the water tank 16 through the connecting pipe, enter the shunt pipe 19 through the hose 18, and finally spray out from the nozzles 20 arranged outside the shunt pipe 19 to cool the steel pipe below. The second motor 23 is started to drive the worm 24 to rotate. By meshing with the worm gear 22, the worm gear 22 is driven to rotate. By means of the worm gear 22, the rotating rod 21 and the shunt pipe 19 are driven to rotate, thereby adjusting the angle of the nozzles 20 outside the shunt pipe 19, enabling uniform spraying on the outside of the steel pipe, improving the cooling effect. The sprayed water is filtered by the filter plate 12 and stored below in the box body 1. The filter plate 12 can be cleaned by pulling it out of the through groove 13. Starting the pump body (not marked in the figure) arranged on the left side of the box body 1 can pump out the water in the box body 1 through the water pipe 25 and enter the water tank 16 for recycling.
