Abstract
Description
Technical Field
[0001] This utility model relates to the field of solar heat exchanger technology, and in particular to a novel automatic tube-threading device for the production of solar heat exchangers. Background Technology
[0002] A solar heat exchanger is a device that utilizes solar energy for heat transfer, primarily used to facilitate heat transfer between two or more fluids at different temperatures. It absorbs solar radiation and transfers heat to the working fluid, moving heat from a high-temperature fluid to a low-temperature fluid to meet process requirements and improve energy efficiency. Solar heat exchangers typically use a low-boiling-point substance as the heat transfer medium and employ multiple U-shaped bends as the heat exchange components. These U-shaped tubes feature a thickened and compact stainless steel design, increasing the heat exchange area and improving efficiency. Furthermore, solar heat exchangers are equipped with a high-grade silicone protective sleeve to prevent wear between the heat exchanger and the water tank; a 316L stainless steel cover to prevent rust; and high-grade dustproof silicone to improve water quality and reduce temperature loss.
[0003] An existing automatic pipe-threading device for the production of a new type of solar heat exchanger is not convenient for workers to easily rotate and adjust the device according to different installation angles when installing it, which affects the ease of operation of the device during product installation. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a novel automatic tube-threading device for the production of solar heat exchangers.
[0005] This utility model is achieved by the following technical solution: a novel automatic pipe-threading device for the production of solar heat exchangers, comprising a movable base plate, a movable handrail fixedly connected to the top of the movable base plate, an adjusting screw connected inside the movable base plate, and a protective base plate fixedly connected to the bottom of the adjusting screw.
[0006] A support plate is fixedly connected to the top of the movable base plate. A rotating shaft is rotatably connected inside the support plate. Limiting plates are fixedly connected to the left and right ends of the rotating shaft. Positioning holes are opened inside the limiting plates. A limiting bracket is fixedly connected to the surface of the support plate. A limiting screw is connected inside the limiting bracket. A rotating base is fixedly connected to the surface of the rotating shaft. A disassembly cover is inserted into the top of the rotating base. A cylinder is inserted into the interior of the rotating base. An installation sleeve is fixedly connected to the front of the cylinder.
[0007] Through the above technical solution,
[0008] As a further improvement to the above scheme, the number of the adjusting screw and the protective base plate is set to four, and each pair forms a group, with the four adjusting screws and the protective base plate symmetrically distributed around the moving base plate.
[0009] As a further improvement to the above solution, the protective base plate is located at the bottom of the movable base plate, and the number of the supporting uprights is set to two, with the two supporting uprights symmetrically distributed on the left and right sides with the movable base plate as the center.
[0010] Through the above technical solution, during the operation of the automatic pipe threading device, the symmetrically distributed adjusting screw can limit the excessive horizontal movement of the moving base plate, ensuring the stability of the device and thus improving the accuracy of the pipe threading operation.
[0011] As a further improvement to the above solution, the supporting plate is located on the front of the movable handrail, and the surface of the limiting plate is in contact with the surface of the supporting plate.
[0012] As a further improvement to the above solution, the number of the limiting brackets and limiting screws is set to four, with each pair forming a group, and the four limiting brackets and limiting screws are symmetrically distributed on the left and right sides with the movable base plate as the center.
[0013] As a further improvement to the above solution, the limiting screw extends through the limiting bracket and the limiting plate to the interior of the supporting plate, and the limiting screw is inserted into the interior of the positioning hole.
[0014] As a further improvement to the above solution, the bottom of the disassembly cover plate contacts the top surface of the cylinder, and the mounting sleeve is located on the front of the rotating base.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] This invention utilizes a rotating limiting screw to allow the rotating shaft to adjust its rotation angle within the supporting plate and limiting bracket when removed from the support plate and limiting bracket. This allows the cylinder and mounting sleeve to adjust the product at different angles during installation. Once the rotating shaft and limiting plate are adjusted to the appropriate positions, the rotating limiting screw extends into the limiting plate and supporting plate, facilitating the limiting and fixing of the rotating shaft and limiting plate after rotation. This ensures the stability of the cylinder and mounting sleeve during material installation.
[0017] This invention, by setting the bottom of the disassembly cover plate to contact the top surface of the cylinder, helps protect the cylinder and prevents external dust and impurities from entering the cylinder, thus ensuring the normal operation of the cylinder. At the same time, the disassembly cover plate is easy to disassemble when the cylinder needs to be repaired or replaced, improving the maintainability of the device. The limit bracket provides support and positioning for the limit screw, ensuring that the limit screw is fixed to the limit plate in the correct position. It can also share the force transmitted from the rotating shaft, protecting the support plate from excessive local pressure, and further improving the overall stability of the device.

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0026] Example:
[0027] Please combine Figure 1-5 This embodiment of an automatic pipe-threading device for the production of a novel solar heat exchanger includes a movable base plate 1, a movable handrail 2 fixedly connected to the top of the movable base plate 1, an adjusting screw 3 connected inside the movable base plate 1, and a protective base plate 4 fixedly connected to the bottom of the adjusting screw 3.
[0028] A supporting plate 5 is fixedly connected to the top of the movable base plate 1. A rotating shaft 6 is rotatably connected inside the supporting plate 5. Limiting plates 7 are fixedly connected to the left and right ends of the rotating shaft 6. Positioning holes 8 are opened inside the limiting plates 7. A limiting bracket 9 is fixedly connected to the surface of the supporting plate 5. A limiting screw 10 is connected inside the limiting bracket 9. A rotating base 11 is fixedly connected to the surface of the rotating shaft 6. A disassembly cover plate 12 is inserted into the top of the rotating base 11. A cylinder 13 is inserted into the inside of the rotating base 11. An installation sleeve 14 is fixedly connected to the front of the cylinder 13. When the rotation limit screw 10 is removed from the inside of the support plate 5 and the limit bracket 9, the rotation angle of the rotating shaft 6 is adjusted inside the support plate 5. This allows the cylinder 13 and the mounting sleeve 14 to adjust the product at different angles. After the rotating shaft 6 and the limit plate 7 are adjusted to the appropriate positions, the rotation limit screw 10 extends into the inside of the limit plate 7 and the support plate 5, which facilitates the limiting and fixing of the rotating shaft 6 and the limit plate 7 after rotation, ensuring the stability of the cylinder 13 and the mounting sleeve 14 when installing materials.
[0029] The number of adjusting screws 3 and protective base plates 4 is set to four, and each pair is a group of four. The four adjusting screws 3 and protective base plates 4 are symmetrically distributed with the movable base plate 1 as the center.
[0030] The protective base plate 4 is located at the bottom of the movable base plate 1, and the number of supporting upright plates 5 is set to two, with the two supporting upright plates 5 symmetrically distributed on the left and right sides with the movable base plate 1 as the center.
[0031] During the operation of the automatic pipe threading device, the symmetrically distributed adjusting screw 3 can limit the excessive horizontal movement of the moving base plate 1, ensuring the stability of the device and thus improving the accuracy of the pipe threading operation.
[0032] The support plate 5 is located on the front of the movable handrail 2, and the surface of the limiting plate 7 is in contact with the surface of the support plate 5.
[0033] The number of limiting brackets 9 and limiting screws 10 is set to four, and each pair is a group of four. The four limiting brackets 9 and limiting screws 10 are symmetrically distributed on the left and right with the movable base plate 1 as the center.
[0034] The limiting screw 10 extends through the limiting bracket 9 and the limiting plate 7 into the interior of the supporting plate 5, and the limiting screw 10 is inserted into the interior of the positioning hole 8.
[0035] The bottom of the disassembly cover 12 contacts the top surface of the cylinder 13, and the mounting sleeve 14 is located on the front of the rotating base 11. By setting the bottom of the disassembly cover 12 to contact the top surface of the cylinder 13, it helps to protect the cylinder 13 and prevent external dust, impurities, etc. from entering the cylinder 13, thereby ensuring the normal operation of the cylinder 13. At the same time, when the cylinder 13 needs to be repaired or replaced, the disassembly cover 12 is easy to disassemble, improving the maintainability of the device. The limiting bracket 9 provides support and positioning for the limiting screw 10. It can ensure that the limiting screw 10 is fixed to the limiting plate 7 in the correct position, and at the same time, it can also share the force transmitted from the rotating shaft 6, protect the supporting plate 5 from excessive local pressure, and further improve the overall stability of the device.
[0036] The implementation principle of the novel automatic pipe-threading device for solar heat exchanger production in this application embodiment is as follows: When the rotating limiting screw 10 is removed from the inside of the support plate 5 and the limiting bracket 9, the rotating shaft 6 rotates at an angle inside the support plate 5. This allows the cylinder 13 and the mounting sleeve 14 to adjust the product at different angles. After the rotating shaft 6 and the limiting plate 7 are adjusted to the appropriate positions, the rotating limiting screw 10 extends into the inside of the limiting plate 7 and the support plate 5, facilitating the limiting and fixing of the rotating shaft 6 and the limiting plate 7 after rotation. This ensures that the cylinder 13 and the mounting sleeve 14 can properly install the material. The stability of the device is improved by setting the bottom of the disassembly cover plate 12 to contact the top surface of the cylinder 13, which helps protect the cylinder 13 and prevents external dust and impurities from entering the cylinder 13, thus ensuring the normal operation of the cylinder 13. At the same time, the disassembly cover plate 12 is easy to disassemble when the cylinder 13 needs to be repaired or replaced, which improves the maintainability of the device. The limit bracket 9 provides support and positioning for the limit screw 10. It can ensure that the limit screw 10 is fixed to the limit plate 7 in the correct position. At the same time, it can also share the force transmitted from the rotating shaft 6, protect the support plate 5 from excessive local pressure, and further improve the overall stability of the device.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
