[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0021] like Figure 1-4 As shown, the injection equipment of new energy fracturing fluid includes a shell 1, and a connecting mechanism 2 is provided on one side of the shell 1. The connecting mechanism 2 includes a pipe 1 3, one end of the pipe 1 3 is fixedly connected to the shell 1, and the other end of the pipe 1 3 is fixedly connected to a fixed block 4, one side of the fixed block 4 is fixedly connected to a cover shell 5, the inner side of the cover shell 5 is rotatably connected to a driving wheel 6, one side of the driving wheel 6 is meshedly connected to a driven wheel 7, one side of the driven wheel 7 is fixedly connected to a pinion 8, the bottom of the pinion 8 is meshedly connected to a gear ring 9, one side of the gear ring 9 is fixedly connected to a screw sleeve 10, the inner side of the screw sleeve 10 is meshedly connected to a pipe 2 11, one end of the pipe 2 11 is fixedly connected to three guide pillars 12, and the outer side of the guide pillars 12 is slidably connected to the fixed block 4.
[0022] In this embodiment, one end of the pipe 2 11 is fixedly connected to the orifice plate 13 , and the inner side of the orifice plate 13 is rotatably connected to the pressure relief plate 14 .
[0023] If leakage occurs at the connection between pipeline 1 3 and pipeline 2 11 , the pressure relief plate 14 and the orifice plate 13 can block the leaked fracturing fluid.
[0024] In this embodiment, a plurality of circular holes are formed on the outer side of the orifice plate 13 , a plurality of circular holes are formed on the outer side of the pressure relief plate 14 , and a plurality of plate-shaped protrusions are formed on the inner side of the pressure relief plate 14 .
[0025] The pressure relief plate 14 can prevent the leakage of the fracturing fluid and allow the leaked fracturing fluid to flow out in a more stable and gentle manner through the circular hole.
[0026] In this embodiment, three circular holes are opened on one side of the fixing block 4 and penetrate to the other side, and the diameter of the circular holes matches the diameter of the guide pillar 12 .
[0027] By inserting the guide column 12 into the circular hole of the fixing block 4, the angle of the pipe 11 can be adjusted to facilitate docking.
[0028] In this embodiment, a knob-shaped protrusion is provided on the top of the driving wheel 6, a circular protrusion is provided at one end of the pinion 8, and T-shaped holes are provided on the top and one side of the fixing block 4.
[0029] The driving wheel 6 and the driven wheel 7 can rotate inside the fixed block 4 and are constrained by the fixed block 4 to move only in the original position.
[0030] In this embodiment, a circular hole is formed at one end of the orifice plate 13 and extends to the other end. An annular groove is formed on the inner wall of the orifice plate 13 , and the length of the groove of the orifice plate 13 matches the length of the pressure relief plate 14 .
[0031] The pressure relief plate 14 is connected to the groove of the orifice plate 13 , and the orifice plate 13 constrains the movement range of the pressure relief plate 14 through the groove.
[0032] In this embodiment, a circular hole is opened on one side of the gear ring 9 and penetrates to the other side, and a circular hole is opened on one side of the screw sleeve 10 and penetrates to the other side, and the inner wall of the circular hole is provided with a thread.
[0033] The gear ring 9 can drive the screw sleeve 10 to rotate outside the pipe 1 3 and the pipe 2 11 , and the screw sleeve 10 is connected to the pipe 2 11 by the rotation.
[0034] It should be noted that the utility model is an injection device for new energy fracturing fluid, which facilitates the docking of pipeline 1 3 and pipeline 2 11 when in use, reduces the difficulty of docking pipeline 1 3 and pipeline 2 11, and can prevent the loss caused by the injection of high-pressure fracturing fluid in the pipeline;
[0035] When connecting the pipe 1 3 and the pipe 2 11, the specific implementation method is to insert the three guide pillars 12 of the pipe 2 11 into the three round holes of the fixing block 4, so that the pipe openings of the pipe 1 3 and the pipe 2 11 are aligned. Since the pipe of the fracturing fluid is heavy, the traditional docking method requires the workbench personnel to hold the pipe to keep the two pipes aligned, which has high work intensity and is more likely to cause work injuries. The guide pillars 12 can keep the pipe 1 3 and the pipe 2 11 aligned and save manpower;
[0036] After the guide column 12 is inserted into the circular hole, the pipe 2 11 is pushed to connect the end with the thread with the screw sleeve 10, and then the driving wheel 6 is rotated. The driving wheel 6 drives the driven wheel 7 to rotate while the driving wheel 6 rotates. The driven wheel 7 drives the pinion 8 to rotate. The pinion 8 drives the gear ring 9 to rotate. The gear ring 9 drives the screw sleeve 10 to rotate while the screw sleeve 10 rotates. The rotation of the screw sleeve 10 will mesh with the pipe 2 11 through the thread, and in the process of meshing, the pipe 2 11 will move toward the direction of the pipe 1 3 until the pipe 1 3 and the pipe 2 11 are tightly connected. Since the number of teeth of the pinion 8 is less than that of the gear ring 9, the torque is greater than the gear ring 9. Therefore, it is more labor-saving to drive the gear ring 9 through the pinion 8 than to directly rotate the gear ring 9, thereby reducing the labor intensity of the staff.
[0037] Since the working pressure of the fracturing fluid is relatively high, when leakage occurs at the connection between pipeline 13 and pipeline 2 11, the fracturing fluid will be ejected under the action of high pressure, which may easily cause damage to equipment and personnel. The fracturing fluid can be blocked by the pressure relief plate 14. The specific implementation method is that when the fracturing fluid is ejected, it will first impact the plate-like protrusion on the inner side of the pressure relief plate 14, and push the pressure relief plate 14 to rotate through the plate-like protrusion. The pressure relief plate 14 can consume the kinetic energy of the torrent by blocking and rotating, and make the decelerated fracturing fluid flow from its own circular hole to the gap between the orifice plate 13, and further block the fracturing fluid through the orifice plate 13, so that the fracturing fluid with consumed kinetic energy flows out through the circular hole of the orifice plate 13, thereby preventing damage to personnel and equipment and increasing the safety protection function of the equipment.
[0038] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
