[0019] The utility model is now described in further detail in conjunction with the accompanying drawings. The accompanying drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0020] Please refer to Figure 1-5 A triangular bracket structure for lifting a water pump for dewatering a pipe well comprises a top plate 4 with a circular cross-section, a plurality of support rods 2 are arranged below the top plate 4, the support rods 2 are hinged to the top plate 4 through a first pin shaft 1, and the support angle and the height of the top plate 4 can be adjusted. A lifting mechanism 5 is arranged on the surface of the top plate 4, and the lifting mechanism 5 comprises a circular fixing cylinder 10, wherein the fixing cylinder 10 can be fixed to the surface of the top plate 4 by welding, bolting, etc., a through hole 14 is arranged at the bottom of the fixing cylinder 10, a horizontally and coaxially arranged rotating shaft 12 and a rotating rod 13 are arranged in the fixing cylinder 10, the rotating rod 13 is arranged on the outer circumference of the rotating shaft 12, and when the rotating shaft 12 rotates, the rotating rod 13 rotates accordingly, and a lifting rope 3 for lifting the water pump is arranged on the rotating rod 13, one end of the lifting rope 3 is fixed on the rotating rod 13, and the other end passes through the fixing cylinder 10 and the top plate 4 at the through hole 14 and extends downward.

[0021] In the utility model, one end of the rotating shaft 12 extends outward and is fixedly connected to the Z-shaped handle 15. The end surface of the Z-shaped handle 15 is provided with an anti-slip thread 16. When the Z-shaped handle 15 rotates, the lifting rope 3 is reeled in through the rotating shaft 12 and the rotating rod 13.

[0022] When in use, the triangular bracket structure is erected at the wellhead of the pipe well through the support rod 2, and then the water pump is transported or lifted into the well through the lifting rope 3; before use, the end of the lifting rope 3 is fixed to the water pump, and the Z-shaped handle 15 is turned when the water pump is transported into the well, at this time, the rotating shaft 12 and the rotating rod 13 are rotated to extend the lifting rope 3, so that the water pump enters the well to extract the internal water; similarly, when the water pump needs to be taken out after use, the Z-shaped handle 15 is turned in the opposite direction, and the lifting rope 3 is rewound by rotating the rotating shaft 12 and the rotating rod 13 again, so that the water pump in the well is lifted and taken out; this process is simple to operate, saves labor, and is highly practical.

[0023] During use, after the Z-shaped handle 15 is rotated to an appropriate position, in order to prevent the Z-shaped handle 15 from loosening and rotating, a tension screw 21 for abutting against the outer wall of the Z-shaped handle 15 is provided on the side wall of the fixed cylinder 10. When the length of the lifting rope 3 is determined, the tension screw 21 is turned to support the outer wall of the Z-shaped handle 15 to prevent the Z-shaped handle 15 from rotating again during use.

[0024] In order to ensure that the rotating shaft 12 and the rotating rod 13 rotate stably in the fixed cylinder 10, annular limit blocks 11 are also provided at both ends of the rotating rod 13. The limit ring is in the shape of a disc. The circumferential outer wall of the limit block 11 is provided with multiple sliding blocks 9. The inner wall of the fixed cylinder 10 is provided with an annular groove 8 that cooperates with the sliding block 9. When the rotating rod 13 rotates, it drives the limit block 11 and the sliding block 9 to slide in the annular groove 8, so that the rotating shaft 12 and the rotating rod 13 are limited in the fixed cylinder 10, so that they rotate stably.

[0025] Furthermore, in order to improve the overall support stability, two adjacent support rods 2 are connected by a reinforcement mechanism 7, and the reinforcement mechanism 7 includes a second pin shaft 17, a fixed rod 18 and a movable rod 20. The fixed rod 18 is hinged to one of the support rods 2 through the second pin shaft 17, and the movable rod 20 is hinged to the other support rod 2. The movable rod 20 and the fixed rod 18 are plug-in connected. The fixed rod 18 is provided with a fixing screw 19, and the fixing screw 19 passes through the fixed rod 18 and rests on the surface of the movable rod 20. After the whole is connected by the reinforcement mechanism 7, each support rod 2 can stably support the top plate, thereby increasing the overall stability.

[0026] In addition, an insertion rod 6 is provided at the bottom of the support rod 2. The end of the insertion rod 6 is tapered. When in use, the insertion rod 6 is inserted into the ground to increase stability while preventing the overall tilt.

[0027] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
