[0030] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0031] Example 1:

[0032] See also Figures 1-6The solar geothermal water circulation pipe welding-free fixing bracket includes a support base 1 for supporting and fixing the water pipe 3. Support plates 101 are symmetrically arranged on both sides of the bottom of the support base 1, and fixing holes 102 are opened on the support plates 101.

[0033] It should be noted that, by setting the fixing holes 102, the support plate 101 can be connected to the platform surface such as the wall or the bottom surface through bolts or other connecting parts, so that the support base 1 can always maintain a stable state during operation.

[0034] A connector 2 is installed on the top of the support base 1. Guide grooves 21 adapted to the water pipe 3 are symmetrically opened at both ends of the interior of the connector 2. A connecting groove 22 is provided between the guide grooves 21 on both sides. The inner diameter of the connecting groove 22 is larger than the inner diameter of the guide groove 21. The guide groove 21 and the connecting groove 22 are separated by a partition plate 23. A docking joint 24 is provided on the side away from each other on both sides of the partition plates 23.

[0035] It should be supplemented that the docking joint 24 includes a progressive tube 241 provided on the partition plate 23 , and a sealing sleeve 242 is connected between the progressive tube 241 and the partition plate 23 .

[0036] In addition, the progressive tube 241 is arranged in a frustum shape, and the inner diameter of the progressive tube 241 gradually decreases on the side away from the partition plate 23. The maximum outer diameter of the progressive tube 241 is consistent with the outer diameter of the sealing sleeve 242. The water pipe 3 is arranged on the outside of the sealing sleeve 242, and the outer diameter of the sealing sleeve 242 is adapted to the inner diameter of the water pipe 3.

[0037] It should be further explained that after the water pipe 3 is sleeved on the outside of the sealing sleeve 242, the inner wall of the water pipe 3 is tightly connected to the outer surface of the sealing sleeve 242. Therefore, the inner diameter of the water pipe 3 is close to the outer diameter of the sealing sleeve 242. When the water pipe 3 is directly sleeved, it is difficult to align and not easy to sleeve. At this time, through the setting of the progressive tube 241, the water pipe 3 can be moved along the outer wall of the progressive tube 241, and under the guiding action of the progressive tube 241, the water pipe 3 can be more easily sleeved on the surface of the sealing sleeve 242.

[0038] In order to further improve the sealing performance of the water pipe 3 after connection, a sealing gasket 25 is provided on the outside of the sealing sleeve 242, so that after the water pipe 3 is sleeved on the sealing sleeve 242, the water pipe 3 continues to move and squeezes the sealing gasket 25, thereby improving the sealing performance between the end of the water pipe 3 and the partition plate 23, and the water pipe 3 can be further sealed.

[0039] In order to ensure the stability of the water pipe 3 after connection, limiting units are symmetrically provided on both sides of the support base 1 , and the limiting units are used to limit the movement of the water pipe 3 .

[0040] The following is a supplementary explanation of the limiting unit: the limiting unit includes a lower support plate 4 installed on both sides of the top of the support seat 1, an upper support plate 41 is provided on the lower support plate 4, connecting wing plates 42 are provided on both sides of the lower support plate 4 and the upper support plate 41, and connecting holes 43 are provided at both ends of the surface of the connecting wing plate 42. A nut 44 is installed at the bottom of the connecting wing plate 42 located on the lower support plate 4, and a locking stud 45 is threadedly connected to the inner side of the nut 44. The inner walls of the upper support plate 41 and the lower support plate 4 are provided with anti-slip rubber pads 46.

[0041] It should be noted that the locking stud 45 passes through the upper and lower connecting holes 43 in sequence and is threadedly connected to the nut 44, so that the locking stud 45 and the nut 44 can cooperate to stably connect the upper support plate 41 and the lower support plate 4.

[0042] Moreover, the longitudinal sections of the upper support plate 41 and the lower support plate 4 are both arc-shaped, and the shapes and sizes of the upper support plate 41 and the lower support plate 4 are adapted to the water pipe 3, so that the lower support plate 4 and the upper support plate 41 cooperate with each other to stably connect and fix the water pipe 3.

[0043] When in use, first connect and fix the support seat 1 to the surface of the carrier through the support plate 101 and the fixing hole 102 in conjunction with the external connecting parts to keep it in a stable state. Then, the operator places the two water pipes 3 that need to be connected and supported on the lower support plates 4 on both sides respectively, and then inserts the water pipes 3 on both sides into the guide grooves 21 on both sides respectively, so that they slide along the inner wall of the guide groove 21, and are sleeved on the surface of the sealing sleeve 242 under the guidance of the progressive tube 241. At the same time, the sealing gasket 25 is squeezed, so that under the double sealing cooperation, the sealing performance of the water pipe 3 can be better.

[0044] After the water pipe 3 is docked, the upper support plate 41 and the lower support plate 4 are assembled, and the two are connected and fixed by using the locking studs 45 and the nuts 44, so that the upper support plate 41 and the lower support plate 4 can stably connect the water pipe 3 and the support seat 1, so that the water pipe 3 has better stability during subsequent use.

[0045] Example 2:

[0046] See also Figure 5 、 Figure 7During the docking process of the water pipe 3, the docking resistance between the water pipe 3 and the sealing sleeve 242 is large, and the operator directly applies thrust to the water pipe 3 manually to make it sleeved on the sealing sleeve 242. The thrust direction cannot always remain coaxial with the sealing sleeve 242, which makes it inconvenient to dock the water pipe 3. Therefore, this embodiment provides a technical solution based on the above embodiment: movable grooves 5 are symmetrically opened at both ends of the top of the support seat 1, and the same bidirectional screw 51 is rotatably connected between the movable grooves 5 on both sides. The two sides of the outside of the bidirectional screw 51 are symmetrically threaded with the movable seat 52. The inside of the support seat 1 is provided with a mounting groove, and the outside of the bidirectional screw 51 is fixedly connected to a worm gear 53 located inside the mounting groove. The inside of the mounting groove is rotatably connected to a worm 54, and the end of the worm 54 is fixedly installed with a handwheel 55 located outside the mounting groove.

[0047] It should be supplemented that the movable seat 52 is slidably connected to the inner side surface of the movable groove 5 , and the shape and size of the movable groove 5 are adapted to the movable seat 52 , and the worm 54 is meshed with the worm wheel 53 .

[0048] During operation, when the end of the water pipe 3 slides along the inside of the guide groove 21 to contact the docking joint 24, the operator assembles the upper support plate 41 and the lower support plate 4 and connects and fixes the two. With the cooperation of the anti-slip rubber pad 46, the connection stability between the water pipe 3 and the lower support plate 4 and the upper support plate 41 is better. Then the operator manually turns the handwheel 55, and the rotation of the handwheel 55 drives the worm 54 to rotate, and the rotation of the worm 54 drives the worm gear 53 to rotate, and the rotation of the worm gear 53 drives the bidirectional screw 51 to rotate, so that the movable seats 52 on both sides move synchronously towards each other, and the movable seat 52 will drive the water pipes 3 on both sides to move synchronously when moving, so that the water pipes 3 on both sides can be pushed to move along the surface of the progressive tubes 241 on both sides at the same time, and be sleeved on the surface of the sealing sleeve 242, thereby making the sleeve connection process of the water pipe 3 more convenient and quick.

[0049] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
