[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the protection scope of the utility model. It is understandable that the drawings are only provided for reference and illustration, and are not used to limit the utility model. The connection relationship shown in the drawings is only for the convenience of clear description and does not limit the connection method.

[0019] Please refer to Figure 1 , Figure 2 and Figure 3 ,in, Figure 1 A structural schematic diagram of a preferred embodiment of a petroleum fracturing drainage device provided by the utility model; Figure 2 It is a structural schematic diagram of the supporting mechanism and the clamping mechanism in the utility model; Figure 3 for Figure 2 A schematic diagram of the structure at A in the middle. A petroleum fracturing drainage device includes an I-shaped base 1, a support mechanism 2 is arranged on the top of the I-shaped base 1, a mounting hole is opened on the inner wall of the I-shaped base 1, a first drainage pipe 3 and a second drainage pipe 4 are arranged on the top of the support mechanism 2, the first drainage pipe 3 and the second drainage pipe 4 are fixedly connected through a flange, a sealing gasket is arranged on the flange, a clamping mechanism 5 is arranged on the inner wall of the support mechanism 2, the support mechanism 2 is used to lift the first drainage pipe 3 and the second drainage pipe 4, and the clamping mechanism 5 is used to clamp and fix the first drainage pipe 3 and the second drainage pipe 4.

[0020] It should be noted that: when the fracturing truck completes the oil layer fracturing construction and needs to drain the liquid generated by the construction, first fix the I-shaped base 1 to the ground through the mounting hole, and then adjust the distance between the clamping mechanisms 5 according to the sizes of the first drainage pipe 3 and the second drainage pipe 4, and lay the first drainage pipe 3 and the second drainage pipe 4 on the supporting mechanism 2. The height of the first drainage pipe 3 and the second drainage pipe 4 can be adjusted by the supporting mechanism 2, and finally the first drainage pipe 3 and the second drainage pipe 4 are clamped and positioned by the clamping mechanism 5.

[0021] In the specific implementation process, Figure 1 and Figure 2 As shown, the support mechanism 2 includes a support column 21 fixed to the top of the I-shaped base 1, a connecting column 22 is slidably connected inside the support column 21, a hand screw 23 is threadedly connected to the inner wall of the support column 21, a threaded hole 24 is provided on the inner wall of the connecting column 22, a support plate 25 is fixedly connected to the top of the connecting column 22, and a cross bar 26 is fixedly connected to one side of the connecting column 22.

[0022] It should be noted that: first, tighten the hand screw 23 to separate it from the threaded hole 24, then move the cross bar 26 to make the connecting column 22 rise and fall through the supporting column 21, so that the support plate 25 can be raised and lowered, and after adjusting to a suitable height, screw the hand screw 23 into and pass through the supporting column 21 to connect with the threaded hole 24, so as to fix the connecting column 22, and finally lay the first drainage pipe 3 and the second drainage pipe 4 on the support plate 25.

[0023] refer to Figure 1 and Figure 2 As shown, the support mechanism 2 further includes a limit block 27 fixed to one side of the connecting column 22 , and a limit groove is provided on the inner wall of the supporting column 21 , and the limit block 27 is slidably connected to the limit groove.

[0024] It should be noted that when the connection column 22 is raised or lowered, the limit block 27 can be driven to move. By the limit block 27 moving in the limit groove, the connection column 22 can be kept stable during the raising or lowering.

[0025] refer to Figure 1 , Figure 2 and Figure 3 As shown, the clamping mechanism 5 includes a screw rod 51 arranged on the inner wall of the support plate 25, one end of the screw rod 51 passes through one side of the support plate 25 and is fixedly connected to a knob 52, the outer side of the screw rod 51 is threadedly connected to a connecting block 53, one end of the screw rod 51 is rotatably connected to the inner wall of the support plate 25 through a bearing seat, the top of the connecting block 53 is fixedly connected to a positioning plate 54, and one side of the positioning plate 54 is provided with an anti-slip pattern 55.

[0026] It should be noted that: when laying the first drainage pipe 3 and the second drainage pipe 4, first turn the knob 52 to rotate the screw rod 51 according to the sizes of the first drainage pipe 3 and the second drainage pipe 4. When the screw rod 51 rotates, the connecting block 53 can drive the positioning plate 54 to move, so that the distance between the multiple groups of positioning plates 54 can be adjusted. Then, the first drainage pipe 3 and the second drainage pipe 4 are laid on the supporting mechanism 2, and then the knob 52 is turned in the opposite direction to bring the multiple groups of positioning plates 54 closer to each other, so that the first drainage pipe 3 and the second drainage pipe 4 of different sizes can be clamped and positioned, thereby improving practicality. The anti-slip groove 55 can increase the friction between the positioning plate 54 and the first drainage pipe 3 and the second drainage pipe 4.

[0027] refer to Figure 1 , Figure 2 and Figure 3 As shown, the clamping mechanism 5 further includes a positioning block 56 fixed to one side of the connecting block 53 , and a positioning groove 57 is formed on the inner wall of the supporting plate 25 , and the positioning block 56 is slidably connected to the positioning groove 57 .

[0028] It should be noted that when the connecting block 53 moves, it can drive the positioning block 56 to move, so that the positioning block 56 slides in the positioning groove 57. Through the coordinated use of the positioning block 56 and the positioning groove 57, it can prevent the connecting block 53 from rotating with the screw rod 51, and at the same time, it can also improve the stability of the connecting block 53 when moving.

[0029] The working principle of a petroleum fracturing drainage device provided by the utility model is as follows:

[0030] When in use, first fix the I-shaped base 1 on the ground, then adjust the height of the supporting mechanism 2, adjust the distance between the multiple groups of positioning plates 54, and then lay the first drainage pipe 3 and the second drainage pipe 4 on the supporting mechanism 2. Through the clamping mechanism 5, it is convenient to install and position the first drainage pipe 3 and the second drainage pipe 4 of different sizes, thereby improving the practicability of the device. The liquid generated during construction is transported through the first drainage pipe 3 and the second drainage pipe 4.
