[0021] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the technical solution of the present invention, but cannot be used to limit the protection scope of the present invention.

[0022] Example:

[0023] like Figures 1 to 4 As shown, the utility model provides a device for coating an anti-corrosion layer on the wall of a HVAC pipe, comprising a HVAC pipe body 1 and a spray pipe 2, the spray pipe 2 is inserted into the HVAC pipe body 1, a connecting plate 101 is provided at one end of the spray pipe 2, a plurality of groups of first connecting parts 102 are also provided on the surrounding side of the connecting plate 101, a stabilizing component is also provided on the plurality of first connecting parts 102 and the spray pipe 2, and the stabilizing component is in contact with the inner wall of the HVAC pipe body 1; both ends of the spray pipe 2 are also connected to the spraying components. The spray pipe 2 can be firmly fixed in the HVAC pipe body 1 by means of multiple groups of first connecting parts 102 on the connecting plate 101 and the stable components connected thereto. The stable spray pipe 2 helps to achieve uniform spraying. Since the position of the spray pipe 2 is fixed in the center of the HVAC pipe body 1 and there will be no unnecessary movement, the device can be kept in an ideal spraying position so that the anti-corrosion coating can be evenly covered on all parts of the inner wall of the pipe, thereby improving the quality and consistency of the anti-corrosion layer. Both ends of the spray pipe 2 are connected to the spray components, which makes the installation and disassembly of the device easier, reduces construction time and labor intensity, and improves the convenience of operation.

[0024] like Figures 1 to 4As shown, the stabilizing component includes a movable ring 3, which can be movably mounted on the spray pipe 2; a second connecting part 201 is also provided on the circumferential side of the movable ring 3 corresponding to the multiple groups of first connecting parts 102, and the multiple groups of first connecting parts 102 and the multiple groups of second connecting parts 201 are respectively rotatably provided with first support rods 202 and second support rods 203, and the multiple groups of first support rods 202 and the multiple groups of second support rods 203 are connected to each other through fixed axes; the multiple groups of first support rods 202 and the multiple groups of second support rods 203 are each provided with a connecting seat 301 at one end close to the HVAC pipe body 1, and a rotating wheel 302 is also rotatably provided on the connecting seat 301, and the multiple groups of rotating wheels 302 are all in contact with the inner wall of the HVAC pipe body 1. The second connection part 201 on the side of the movable ring 3 is combined with the first connection part 102 on the connecting plate 101 to form a connection point for the first support rod 202 and the second support rod 203, which not only ensures the stable fixation of the two groups of support rods, but also allows them to be flexibly moved on the device. Through this flexibility, the first support rod 202 and the second support rod 203 can be adjusted and changed in angle as needed to adapt to different work requirements and operating environments. This enhances the adaptability and practicality of the device.

[0025] By utilizing the mobility of the movable ring 3, the cross connection between the first support rod 202 and the second support rod 203 can be controlled to form a stable support frame. This structure can effectively disperse pressure and weight, prevent the spray pipe 2 from shaking or shifting during operation, thereby ensuring the stability and consistency of the spraying operation; at the same time, the movable ring 3 can be movably mounted on the spray pipe 2, which allows the position to be adjusted according to actual needs, thereby controlling the cross angle of the first support rod 202 and the second support rod 203, which means that the device can adapt to HVAC pipes of different diameters, thereby improving the flexibility and convenience of operation.

[0026] The rotating wheel 302 on the connecting seat 301 is in close contact with the inner wall of the HVAC pipe body 1. The rolling motion of the rotating wheel 302 can ensure the mobility of the HVAC pipe body 1. When the device is in use, the rotating wheel 302 can be used to easily push the device into the deep of the HVAC pipe body 1. At the same time, the rotating wheel 302 is made of rubber, which can increase the friction between the rotating wheel 302 and the HVAC pipe body 1, thereby ensuring the stability of the device when it is deep. In addition, the rubber rotating wheel 302 can also effectively protect the inner surface of the HVAC pipe from being scratched, thereby ensuring the effective spraying of the anti-corrosion coating of the device.

[0027] The stabilizing component also includes a stabilizing ring 4. An internal thread is also provided on the outer surface of the spray pipe 2. The stabilizing ring 4 is movably inserted into the spray pipe 2 through the internal thread, and one end of the stabilizing ring 4 is in contact with the movable ring 3. The combination of the stabilizing ring 4 and the spray pipe 2 effectively fixes the connection between the movable ring 3 and the spray pipe 2, preventing the occurrence of instability due to looseness during use. The movable setting of the stabilizing ring 4 allows the device to be flexibly moved when adjustment is required, while maintaining a stable supporting effect, ensuring the safe operation and work efficiency of the device. In addition, the contact between the stabilizing ring 4 and the movable ring 3 can also evenly distribute the force, reduce the impact of local stress on the equipment, and extend the service life of the device.

[0028] like Figures 2 to 4 As shown, the spray assembly includes a feed pipe 501, and a feed trough 502 is provided on the side of the connecting plate 101 away from the spray pipe 2, and an assembly part 503 is provided at one end of the feed pipe 501 corresponding to the feed trough 502, and the feed pipe 501 is detachably arranged in the feed trough 502 through the assembly part 503; the spray assembly also includes a liquid distributor 5, and a discharge port 601 is provided at the other end of the spray pipe 2 away from the connecting plate 101, and a connecting part 602 is provided at one end of the liquid distributor 5 corresponding to the discharge port 601, and the connecting part 602 is detachably arranged in the discharge port 601; a plurality of groups of assembly holes 701 are evenly provided on the surrounding side of the liquid distributor 5, and nozzles 702 are all arranged in the plurality of groups of assembly holes 701. By detachably setting the feed pipe 501 and the liquid distributor 5 in the feed trough 502 and the discharge port 601, the spray assembly can be easily loaded and unloaded. When a component needs to be replaced or repaired, there is no need to disassemble the entire device, which simplifies the maintenance and cleaning of the equipment and further improves the maintenance efficiency. At the same time, since the feed pipe 501 and the liquid distributor 5 are both detachable, the spray assembly has high flexibility. According to different process requirements or spraying objects, nozzles 702 and liquid distributors 5 of different specifications or types can be quickly replaced to adapt to different production needs, thereby improving the applicability of the device.

[0029] Multiple groups of assembly holes 701 are evenly arranged on the circumference of the liquid distributor 5, allowing multiple nozzles 702 to work at the same time. This not only greatly increases the spray coverage area and significantly improves the overall spray efficiency, but also makes the spraying process faster and more efficient when multiple nozzles 702 are started at the same time, greatly shortening the time required for a single spraying operation, so that it can complete a large area of ​​uniform spraying tasks in a short time, reducing working hours and improving production efficiency. In addition, since the nozzles 702 are evenly distributed, it is also ensured that each nozzle 702 can be accurately positioned and operated synchronously, so that the spraying material can seamlessly cover every part of the inner wall of the HVAC pipe body 1, thereby avoiding the problem of spraying dead angles or overspraying during spraying, and thus providing a higher spraying effect.

[0030] The above description is only an implementation method of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
