[Technical Field]

[0001] This invention relates to the technical field of deep well construction, and more particularly to a deep well pipe bottom tray structure. [Background technology]

[0002] During deep well construction, the connection between the tray and the bottom of the deep well pipe provides support and space for the deep well pipe, and also separates and filters out bulky debris at the bottom of the deep well, preventing it from blocking the deep well pipe and affecting its use. However, when using a conventional tray structure, there is no pre-installed structure between the tray components, and a direct welding connection method is used, which makes it difficult to control the accuracy of the connection position during the connection operation, further affecting the overall connection accuracy. Summary of the Invention [Problem to be solved by the invention]

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0011] The connection between the connecting frame and the screw realizes the effect of the connecting frame providing support to the bottom end of the well pipe through the abutment contact between the screw and the well pipe. Through the connection between the connecting frame and the connecting barrel, the connection between the connecting barrel and the support rod, and the connection between the support rod and the fixed barrel, the effect of the supporting rod providing support between the connecting frame and the mounting plate is realized.

[Figure 4] 1 is a schematic exploded perspective view of a portion of the connection structure between the connection frame and the mounting plate of the present invention; DETAILED DESCRIPTION OF THE INVENTION

[0013] Referring to Figures 1 to 4, one embodiment of the present invention: The deep well pipe bottom tray structure includes a well pipe 1 and a connecting frame 2, a screw 21 penetrating the surface of the connecting frame 2 with a screw thread to connect them, the connecting frame 2 abuts against the bottom end of the well pipe 1 via the screw 21, a connecting tube 22 is fixedly connected to the bottom end of the connecting frame 2, a support rod 3 is connected to the inside of the connecting tube 22 with a screw thread, a fixed tube 41 is fitted to the end of the support rod 3 away from the connecting tube 22, a mounting plate 4 is fixedly connected to the surface of the fixed tube 41, and a connecting rod 5 is fixedly connected to the middle position of the mounting plate 4, the connecting frame 2 and the well pipe 1, the support rod 3 and the connecting tube 22, and the support rod 3 and the fixed tube 41 are reinforced and connected together by welding after the connection is completed, the connection between the well pipe 1 and the connecting frame 2, the connection between the connecting frame 2 and the connecting tube 22, the connection between the connecting tube 22 and the support rod 3, and the connection between the support rod 3 and the fixed tube 41 provide a connection and support effect for the mounting plate 4.

[0014] Furthermore, the cross section of the connecting frame 2 is "L" shaped, and the connecting frame 2 is annular and fitted to the bottom end of the well pipe 1. Through the fitting of the connecting frame 2 and the well pipe 1, the action of the connecting frame 2 realizes a supporting effect for the connection position of the mounting plate 4 and the connecting rod 5 on the well pipe 1.

[0015] Furthermore, the screws 21 penetrate the connecting frame 2 and come into contact with the outer surface of the well pipe 1, and the screws 21 are uniformly distributed on the outer surface of the connecting frame 2. By connecting the well pipe 1 to the connecting frame 2, the connection between the connecting frame 2 and the screws 21 brings the screws 21 into contact with the well pipe 1, thereby achieving the mounting support effect of the connecting frame 2 on the well pipe 1.

[0016] Furthermore, the connecting tube 22 matches the shape of the fixed tube 41, and the connecting tube 22 and the fixed tube 41 are distributed on both ends of the support rod 3. Through the connection between the connecting tube 22 and the connecting frame 2 and the connection between the mounting plate 4 and the fixed tube 41, the connection between the support rod 3 and the connecting tube 22 and the connection between the support rod 3 and the fixed tube 41 realizes the effect of connecting and supporting the support rod 3 at the connecting frame 2 and the mounting plate 4.

[0017] Furthermore, the support rods 3 are uniformly distributed between the connecting frame 2 and the mounting plate 4, and the mounting plate 4 acts below the connecting frame 2 through the support rods 3. By connecting the support rods 3 to the connecting frame 2 and the mounting plate 4, the support rods 3 function to provide a connecting support effect for the connecting frame 2 and the mounting plate 4, and also realize the effect of partitioning and filtering the connection.

[0018] Furthermore, the connecting rod 5 is a round bar, and through the connection between the mounting plate 4 and the connecting rod 5, the supporting stability performance of the connection between the mounting plate 4 and the bottom of the deep well is improved.

[0019] Working principle: When the connecting frame 2 and the well pipe 1 are installed, the connecting frame 2 is connected to the screw 21, and the abutment contact between the screw 21 and the well pipe 1 realizes the effect of pre-installing the connecting frame 2 on the well pipe 1; the connection between the connecting frame 2 and the connecting tube 22, and the connection between the mounting plate 4 and the fixed tube 41, realizes the effect of supporting the connecting position of the support rod 3; when the part installation operation is completed, welding operation is performed at the connection point, which improves the connection stability and solidity.
