[0029] It is worth noting that the circuits, electronic components and modules involved in the present utility model are all prior art and can be fully implemented by those skilled in the art. Needless to say, the content protected by the present utility model does not involve improvements to software and methods.

[0030] The working principle of the support device for downhole fracturing operation provided by the utility model is as follows:

[0031] When in use, the support outer frame 1 is placed at the bottom of the well, and then can be inserted into the bottom soil of the well by rotating a plurality of screws 5, so that the support outer frame 1 can be well fixed. The support plates arranged at the four corners of the top of the support outer frame 1 fix the accommodating chamber of the fracturing mechanism. In this way, when the fracturing mechanism is placed in the accommodating chamber, the support plate and the support outer frame 1 play a good supporting role, and the support outer frame 1 can also be conveniently removed by rotating the thread. Four pipe holes are arranged at the parallel ends of the support plate and the support outer frame 1 for placing high-pressure air pipes. Under the high pressure of the fracturing mechanism, the high-pressure air pipes are cracked at the bottom of the well and liquid gunpowder is injected through the pipe holes. An outer protective cover is arranged at the top of the support plate at the periphery of the accommodating chamber of the fracturing mechanism. The height of the outer protective cover is greater than the height of the accommodating chamber of the fracturing mechanism to prevent debris from splashing. Side plates 19 are arranged on the four sides of the top of the support outer frame 1, and the upper part of the side plate 19 is a cavity. Because the bottom of the side plate 19 is a solid, this can prevent the side wall of the well bottom from collapsing and blocking the well bottom of the support outer frame 1. The arrangement of the cavity ensures air permeability.

[0032] When fixing the supporting outer frame 1 to the bottom of the well or removing the supporting outer frame 1 from the bottom of the well, it is necessary to start the dual-axis motor 14 in the two driving mechanisms, the dual-axis motor 14 will drive the rotating shaft 15 to rotate, the rotating shaft 15 will drive the first bevel gear 16 to rotate, the first bevel gear 16 will drive the mounting column 7 to rotate through the second bevel gear 17, the mounting column 7 will drive the clamping block 8 to rotate, the clamping block 8 will drive the screw 5 to rotate, because the screw 5 is threadedly connected to the screw sleeve 4, the screw 5 can be moved vertically while rotating, so that the screw 5 can be inserted into the bottom soil at the bottom of the well, or the screw 5 in the soil can be moved out, because the multiple screws 5 on the device can be moved vertically at the same time when the two driving mechanisms are started, so that a lot of time can be saved in the fixing or removal of the supporting outer frame 1, and the physical strength of employees can also be saved, which can improve work efficiency.

[0033] When it is necessary to remove the screw 5 from the device, first open the inspection door 18, then pull the pull rod 10, the pull rod 10 will drive the baffle 12 to move, the baffle 12 will squeeze the spring 11, and the baffle 12 will also drive the plug 13 to disengage from the slot. After disengagement, the screw 5 can be taken out of the screw sleeve 4 by manually rotating the screw 5, so that the block 8 is disengaged from the slot on the mounting column 7. If the pull rod 10 is released before rotation, the spring 11 will automatically push the baffle 12 to move, and the baffle 12 will drive the plug 13 to move, so that the plug 13 enters the slot of the block 8, so that the screw 5 cannot be removed, and the operation is relatively simple.

[0034] Compared with the related art, the support device for downhole fracturing operation provided by the utility model has the following beneficial effects:

[0035] The utility model provides a supporting device for downhole fracturing operations, which constitutes the main body of the supporting device for downhole fracturing operations in the prior art through a supporting outer frame 1, and can facilitate employees to disassemble or install multiple screws 5 through multiple disassembly mechanisms, and can simultaneously drive multiple screws 5 to rotate through two driving mechanisms. Under the action of multiple threaded sleeves 4, multiple screws 5 will move vertically while rotating, so that a lot of time can be saved in the fixing or removal of the supporting outer frame 1, and the physical strength of employees can be saved, which can improve work efficiency. The stability of the two cross plates 6 in the vertical movement can be guaranteed through multiple sliding grooves and multiple sliding blocks, and the multiple rotating shafts 15 can be better supported by multiple positioning plates.
