[0031] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0032] Refer to Figure 1 - Figure 2, an embodiment provided by the present utility model: a cooling device for processing prestressed steel strands, including a support frame 1. The support frame 1 is composed of a vertical rod and an upper sliding wheel. The steel strand can be driven by the rotation of the sliding wheel to slide into the cooling tank 5 for water cooling. A water circulation component is fixedly connected to the outer part of the lower end of the support frame 1. The water circulation component includes a receiving tank 3. The receiving tank 3 can collect the water scattered on the steel strand for recycling. A water pump 2 is fixedly connected to the side end of the receiving tank 3. The water pump 2 can circulate the water inside the receiving tank 3 to the inside of the upper square tank 4. The upper part of the water pump 2 is fixedly connected to the square tank 4. The square tank 4 can guide the water flow into the inside of the water outlet tank 9 for preliminary water cooling. A cooling tank 5 is fixedly connected to the right part of the receiving tank 3. The steel strand can be pulled into the cooling tank 5 for water cooling through the sliding wheel inside the cooling tank 5. The inner wall of the lower end of the receiving tank 3 is fixedly connected to the lower part of the support frame 1.

[0033] Refer to Figure 2 - Figure 4 , a motor 6 is fixedly connected to the side end of the support frame 1. The motor 6 can drive the sliding wheel at the upper end of the support frame 1 to rotate. A rotating disk 8 is rotatably connected to the side part of the upper end of the support frame 1. The rotating disk 8 can rotate with the sliding wheel, so that the arc-shaped block 7 can rotate accordingly. An arc-shaped block 7 is fixedly connected to the side end of the rotating disk 8. When the arc-shaped block 7 rotates, it can squeeze so that the pull rod 13 can slide horizontally in a straight line. The pull rod 13 is in contact with the outer part of the side end of the rotating disk 8. A closing plate 10 is fixedly connected to the upper part of the pull rod 13. The pull rod 13 is Z-shaped. When the lower end is squeezed by the arc-shaped block 7, it can slide towards both ends, so that the closing plate 10 can slide towards both ends to open the lower end of the water outlet tank 9, enabling the water flow to fall onto the steel strand for preliminary water cooling to reduce its temperature by a certain amount first, preventing deformation due to excessive temperature when being pulled in the cooling tank 5. The upper part of the closing plate 10 is in contact with the bottom of the water outlet tank 9. The side end of the closing plate 10 is elastically connected to a clamping groove 12 through a first spring 14. When the first spring 14 is squeezed, the two closing plates 10 can be closed so that the water outlet tank 9 does not discharge water. The inner part of the clamping groove 12 is slidably connected to the outer wall of the positioning block 11. The clamping groove 12 is clamped by the positioning block 11 to remain fixed, so that the closing plate 10 can only slide horizontally in a straight line within a fixed distance. One end of the first spring 14 is fixedly connected to the side part of the closing plate 10, and the other end of the first spring 14 is fixedly connected to the outer side end of the clamping groove 12. When the first spring 14 is squeezed, the closing plate 10 can be kept in a closed state. A sliding rod 15 is fixedly connected to the side end of the clamping groove 12. The outer part of the sliding rod 15 is slidably connected to the inner part of the side end of the closing plate 10. The sliding rod 15 supports the closing plate 10 to only slide horizontally in a straight line. A positioning component is slidably connected to the inner part of the clamping groove 12. The side end of the positioning component is fixedly connected to the water outlet tank 9. The water outlet tank 9 can store water so that the water flow can fall straight onto the steel strand. The upper part of the water outlet tank 9 is fixedly connected to the lower part of the square tank 4.

[0034] Refer to Figure 3 - Figure 5, the positioning component includes a positioning block 11. The positioning block 11 is L-shaped, restricting the card slot 12 to slide only horizontally in a straight line. The side of the positioning block 11 is fixedly connected to the outer side of the side end of the water outlet groove 9, and the water outlet groove 9 keeps the positioning block 11 relatively fixed. Inside the positioning block 11, a connecting rod 17 is elastically connected through a second spring 18. The connecting rod 17 can drive multiple sets of clamping blocks 16 to slide upward to clamp the card slot 12 to keep it fixed. One end of the second spring 18 is fixedly connected to the lower end inside the positioning block 11, and the other end of the second spring 18 is fixedly connected to the lower part of the connecting rod 17. The second spring 18 is in a state of squeezing the connecting rod 17 under the extrusion of the positioning block 11. The upper part of the connecting rod 17 is fixedly connected with a clamping block 16. The upper end of the clamping block 16 is an arc surface. By sliding one end of the clamping block 16 downward, the arc surface can be extruded by the card slot 12 and slide into the inside of the positioning block 11 so that the card slot 12 can be slid out for replacement, preventing the first spring 14 from aging and becoming unusable, and enabling quick replacement. The outside of the clamping block 16 is slidably connected to the upper inside of the positioning block 11 and the upper inside of the card slot 12.

[0035] Working principle: The motor 6 can drive the sliding wheel at the upper end of the support frame 1 to rotate, guiding the wire into the cooling tank 5 for cooling. The rotation of the sliding wheel can drive the rotating disk 8 to rotate, and the rotating disk 8 can drive the arc-shaped block 7 to rotate. The arc-shaped block 7 can be extruded to make the pull rod 13 slide towards both ends. The pull rod 13 can drive the closing plate 10 to slide towards both ends, squeezing the first spring 14. At this time, the water flow inside the water outlet groove 9 drops onto the steel wire for preliminary cooling. Subsequently, the rotating disk 8 continues to drive the arc-shaped block 7 to rotate. At this time, the first spring 14 drives the closing plate 10 to slide horizontally back to its original position, closing the lower part of the water outlet groove 9, and the water flow flows into the inside of the receiving tank 3. The water inside the receiving tank 3 is circulated to the inside of the square groove 4 through the water pump 2, and then the water flow inside the square groove 4 flows into the inside of the water outlet groove 9. When the first spring 14 ages, the clamping block 16 can be slid downward for a certain distance, and then the card slot 12 can be slid horizontally. The card slot 12 extrudes the arc surface of the clamping block 16 to slide it into the inside of the positioning block 11, squeezing the second spring 18, enabling the card slot 12 to be replaced. Slide the new card slot 12 to the outside of the positioning block 11. At this time, the clamping block 16 and the connecting rod 17 slide upward under the extrusion of the second spring 18 to clamp and fix the card slot 12.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
