It is movably connected near the center, and the two water supply pipes 18 are connected to a hose 13 at the center of one end of the top away from the center of the inner cavity of the cooling box 1. A second through hole is opened at the center of the side of the top of the two U-shaped frames 17 away from the center of the inner cavity of the cooling box 1. The two hoses 13 are movably connected in the adjacent second through holes near the bottom end. A first fixing hole is opened at the bottom of the diversion box 7 near the center of the left and right sides. The side walls of the two hoses 13 are connected to the inner walls of the adjacent first fixing holes near the top. There is a water storage tank 11 at the bottom of the ring 14, and the bottom of the water storage tank 11 is connected to the inner wall of the bottom of the cooling box 1 near the center. There is a drive assembly 6 at the top of the cooling box 1; the drive assembly 6 includes a connecting box 61 connected to the top of the cooling box 1 near the center, and the cross-section of the connecting box 61 is U-shaped, and the U-shaped structure of the connecting box 61 opens downward.

[0022] It should be noted that, since the existing hot-dip galvanizing cooling device for steel wire has a poor cooling effect and cannot recycle and reuse the sprayed water, resulting in a waste of resources, in order to solve the problems arising during the use of the existing hot-dip galvanizing cooling device for steel wire, this solution solves the problem that the existing hot-dip galvanizing cooling device for steel wire has a poor cooling effect and cannot recycle and reuse the sprayed water, resulting in a waste of resources, by adding a drive component 6 on the top of the cooling box 1 and coordinating the use of various components on the front side of the cooling box 1 and the upper and lower sides of the inner cavity.

[0023] In a further preferred embodiment of the present invention, Figure 1 、 2As shown in FIG4 , two support plates 610 are provided at the bottom of the connection box 61 near the center of the left and right sides, and the two support plates 610 on the left and right sides are connected to the inner walls of the left and right sides of the cooling box 1 near the center of the top, respectively, away from the center of the inner cavity of the connection box 61. The adjacent sides of the two support plates 610 on the left and right sides are both movably connected to the reciprocating screw rods 68 near the center, and the thread tapping directions of the two reciprocating screw rods 68 are opposite. A drive sleeve 69 is provided on the two reciprocating screw rods 68 near the center, and the two drive sleeves 69 are connected to the inner walls of the cooling box 1 near the center. 9 The adjacent side is connected to the adjacent U-shaped frame 17 near the center away from the inner center of the cooling box 1, and the two water supply pipes 18 are connected to the return spring 19 near the center of the inner center of the cooling box 1. The two return springs 19 are respectively connected to the center of the side of the adjacent drive sleeve 69 near the center of the inner center of the cooling box 1 at one end away from the inner center of the cooling box 1. The inner cavities of the two drive sleeves 69 are provided with drive holes near the center, and the inner walls of the two drive holes are provided with internal threads matching the adjacent reciprocating screw rod 68.

[0024] In this embodiment, when the steel wire hot-dip galvanizing cooling device is used to cool the hot-dip galvanized steel wire, the staff first inserts the steel wire to be cooled from the rear side of the cooling box 1 into the cooling box 1. At this time, the staff pulls the steel wire forward to cool it. When the two nozzles 16 spray the cooling water introduced into the diverter box 7, the staff drives the two reciprocating screws 68 to rotate synchronously. Since the thread tapping directions of the two reciprocating screws 68 are opposite, the two reciprocating screws 68 can drive the two drive sleeves 69 to move back and forth alternately. When the two drive sleeves 69 move back and forth alternately, they can drive the two U-shaped frames 17 to move back and forth alternately. When the two water supply pipes 18 slide alternately up and down inside the two arc-shaped chutes, the two water supply pipes 18 can be continuously extended and retracted inside the two U-shaped frames 17 when moving alternately up and down, thereby ensuring the integrity of the cooling device structure. When the two water supply pipes 18 slide alternately up and down inside the two arc-shaped chutes, the two nozzles 16 can be driven to slide alternately up and down on the inner wall of the ring 14, so that the two nozzles 16 can spray cooling water on the steel wire in a circular shape to cool it, thereby achieving the purpose of all-round cooling operation on the steel wire, avoiding the problem of cooling dead corners in the cooling process of the steel wire, and thus improving the cooling effect of the device.

[0025] In a further preferred embodiment of the present invention, Figure 2 and 4As shown, the inner cavity of the connecting box 61 is provided with a driven sprocket 66 near the center of the left and right sides, and the bottoms of the two driven sprockets 66 are movably connected to the top of the cooling box 1 near the center of the left and right sides, and the bottoms of the two driven sprockets 66 are connected to a rotating rod 67 near the center. The inner cavity of the two support plates 610 at the top of the cooling box 1 near the center of the left and right sides is respectively provided with a first and a second rotating hole, and the bottom ends of the two rotating rods 67 pass through the adjacent first and second rotating hole cavities in turn, and are both close to the top of the adjacent reciprocating screw rod 68. The two driven sprockets 66 are connected at the center, and a driving sprocket 64 is provided on one adjacent side of the two driven sprockets 66. A chain 65 is engaged with the driving sprocket 64 and the two driven sprockets 66. The driving sprocket 64 and the two driven sprockets 66 are connected by the chain 65. A driving motor 63 is provided on the top of the driving sprocket 64, and the bottom end of the power output shaft of the driving motor 63 is connected to the top of the driving sprocket 64 near the center. A groove is provided near the center of the top of the inner cavity of the connecting box 61, and the top of the driving motor 63 is connected to the inner wall of the top of the groove near the center.

[0026] In this embodiment, when the two nozzles 16 spray out the cooling water introduced into the diversion box 7, at the same time, the staff also starts the drive motor 63 through an external power supply, so that the drive motor 63 can drive the drive sprocket 64 to rotate when powered on. When the drive sprocket 64 rotates, it engages with the chain 65, thereby driving the chain 65 to rotate. Since the chain 65 rotates and engages with the two driven sprockets 66, it can drive the two driven sprockets 66 to rotate synchronously, so that the two driven sprockets 66 can drive the two reciprocating screws 68 to rotate synchronously through the two rotating rods 67.

[0027] In a further preferred embodiment of the present invention, Figure 1 and 2 As shown, heat dissipation holes are provided at the top of the connection box 61 near the center of the left and right sides, and dustproof nets 62 are provided in the inner cavities of the two heat dissipation holes, and the side walls of the two dustproof nets 62 are connected to the inner walls of the adjacent heat dissipation holes.

[0028] In this embodiment, heat dissipation holes are opened on the top of the connection box 61, so that the heat generated by the drive motor 63 can be dissipated, thereby avoiding the problem that the drive motor 63 is affected by the temperature and cannot work stably. At the same time, dustproof nets 62 are connected to the inside of the two heat dissipation holes, so that the two dustproof nets 62 can block external dust and prevent dust from entering the inside of the connection box 61.

[0029] In a further preferred embodiment of the present invention, Figure 1As shown, first connecting holes are provided on the front side of the diversion box 7 near the top center, the front side of the condenser 10 near the bottom center, and the front side of the cooling box 1 near the upper and lower centers, and the inner cavities of several first holes are commonly connected to the hard water pipe 2, and the hard water pipe 2 is connected to the pump body 5 near the top.

[0030] In this embodiment, when the steel wire to be cooled passes into the cooling box 1 from the rear side, the staff starts the pump body 5 through an external power supply, so that the pump body 5 can introduce the cooling water inside the water tank 11 into the diversion box 7 through the hard water pipe 2, and then spray it out through the two nozzles 16 to cool the steel wire.

[0031] In a further preferred embodiment of the present invention, Figure 1 and 2 As shown, second connecting holes are provided near the center on both sides of the front and rear of the cooling box 1, and the inner cavities of the two second connecting holes are provided with limiting cylinders 3, and the side walls of the two limiting cylinders 3 are connected to the inner walls of the adjacent second connecting holes near the adjacent side, and a glass plate 4 is provided on the top of the limiting cylinder 3 on the front side, and an observation port is provided near the top center on the front side of the cooling box 1, and the side walls of the glass plate 4 are connected to the inner wall of the observation port near the rear side.

[0032] In this embodiment, by connecting limiting cylinders 3 on both the front and rear sides, the two limiting cylinders 3 can limit the position of the steel wire, so that the steel wire can pass smoothly from the inside of the cooling box 1 for cooling operation. At the same time, by connecting a glass plate 4 near the top on the front side, it is convenient for the staff to observe the cooling condition of the steel wire through the glass plate 4.

[0033] In a further preferred embodiment of the present invention, Figure 2 As shown, a condenser 10 is connected to the inner wall of the bottom of the water tank 11 near the center, a water inlet is provided near the center of the top of the water tank 11, a water collecting cover 12 is connected to the inner cavity of the water inlet, and the side wall of the water collecting cover 12 is connected to the inner wall of the cooling box 1 near the bottom, a second fixing hole is provided on the left side of the water tank 11 and the cooling box 1 near the center of the bottom, and the inner cavities of the two second fixing holes are commonly connected to a water pipe 9, and a valve 8 is connected to the water pipe 9 near the left end.

[0034] In this embodiment, when the two nozzles 16 spray cooling water on the steel wire to cool it, the water collecting cover 12 can quickly collect the sprayed water, and then the water collecting cover 12 will guide the water into the water storage tank 11 for recycling, thereby avoiding the waste of resources, being more energy-saving and environmentally friendly, and thus improving the practicality of the device to a certain extent. By connecting the water storage tank 11 and the left side of the bottom of the cooling box 1 with a water pipe 9, the water can be guided into the water storage tank 11 through the water pipe 9 by opening the valve 8 to prepare for the cooling operation of the steel wire. When water is added to the water storage tank 11, at this time the staff will close the valve 8 to close the water pipe 9 to prevent the water entering the water tank 11 from flowing out. Then the staff will start the condenser 10 through an external power supply, so that the condenser 10 can cool the water inside the water tank 11, and then the cooling water inside the water tank 11 can be quickly sprayed out through the two nozzles 16 to cool the steel wire. At the same time, the water entering the water tank 11 again can also make the condenser 10 cool again, so that the two nozzles 16 can always spray cooling water to better cool the steel wire.
