[0019] like Figure 1 As shown, the present invention provides an electric testing environmental protection plug, comprising: a column 3; The column 3 is a hollow structure, the upper end of the column 3 is provided with an internal thread, the interior of the column 3 is provided with an overflow channel 2, the column 3 is detachably connected to the blowout preventer, the overflow channel 2 is communicated with the top of the blowout preventer, the blowout preventer is formed in the blowout preventer, a sealing packing 1 is arranged in the overflow channel 2, the sealing packing 1 is composed of annular sealing rings made of rubber superimposed, the cross section of the sealing ring is V-shaped so as to expand laterally when subjected to downward pressure, the sealing packing 1 and the overflow channel 2 form an annular water accumulation cavity, one side of the water accumulation cavity is provided with an overflow port 4, the overflow port 4 is used to discharge the liquid in the overflow channel; an upper pressure piece 5 is provided on the top of the sealing packing 1, the The upper pressure piece 5 is used to apply the required working pressure to the sealing packing 1. The lower end of the upper pressure piece 5 is provided with an external thread, and the upper pressure piece 5 is threadedly connected to the top of the column 3; the upper end of the upper pressure piece 5 is connected to the driven gear 6 and is driven by the driven gear 6 to work. The upper pressure piece 5 is composed of an upper pressure cap, a packing pressure cap and a wiper packing, and the upper pressure cap, the packing pressure cap and the wiper packing are coaxially arranged. The driven gear 6 meshes with the driving gear 7, and the driving gear 7 is connected to the driving motor 8 and is driven by the driving motor 8 to work; the driving motor 8 is installed on one side of the column 3 through a motor fixing bracket. The working state of the driving motor 8 can be remotely controlled by the user. The driving motor 8 is connected The ground power supply is connected, and the positive and negative poles of the voltage are controlled to be turned on through the ground control switch to control the rotation direction of the driving motor 8. The driving motor 8 drives the driving gear 7. The driving gear 7 drives the driven gear 6 meshing with it, so that the pressure applied to the sealing packing 1 made of elastic material can be changed by controlling the driving motor 8 to rotate the upper pressure piece 5 clockwise and counterclockwise. By rotating the upper pressure piece 5 clockwise, it moves downward along the thread to squeeze the sealing packing 1. By rotating the upper pressure piece 5 counterclockwise, it moves upward along the thread to move away from the sealing packing 1. A through hole is set in the middle of the sealing packing 1. When the upper pressure piece 5 moves along the thread, the sealing packing 1 is pressed. When the sealing packing 1 is vertically squeezed, the vertical pressure on the sealing packing 1 increases, the sealing packing 1 will expand and reduce the cross-sectional area of ​​the through hole provided on the sealing packing 1, thereby achieving the purpose of increasing the sealing degree; when the upper pressure piece 5 moves away from the sealing packing 1 vertically, the vertical pressure on the sealing packing 1 decreases, the sealing packing 1 will shrink and increase the cross-sectional area of ​​the through hole provided on the sealing packing 1, thereby achieving the purpose of reducing the sealing degree; the driving gear 7 and the driven gear 6 are meshed with each other, and the number of teeth of the driving gear 7 is less than one-third of the number of teeth of the driven gear 6, which is used to reduce the rotation speed while increasing the torque to achieve the purpose of a reducer.

[0020] It should be noted that in order to prevent the sealing packing 1 made of elastic material from being worn and aging and deformed when the upper pressure piece 5 is rotated and extruded along the thread, a fixing piece and a rotating piece can be provided to protect the sealing packing 1 to a certain extent. The fixing piece is detachably fastened to the top of the sealing packing 1, and the lower end of the rotating piece is rotatably connected to the fixing piece, and the upper end of the rotating piece is connected to the bottom of the upper pressure piece 5, so that the upper pressure piece 5 will not directly contact the upper end surface of the sealing packing 1 when rotating, thereby reducing the greater wear on the upper end of the sealing packing 1 during the downward rotation and extrusion of the sealing packing 1 by the upper pressure piece 5; the rotating piece and the fixing piece can be non-standard parts or standard parts, and the purpose of reducing the wear of the sealing packing 1 can also be achieved by setting the rotating piece and the fixing piece as bearings, and the two parts of the bearing are detachably fixedly connected to the bottom of the upper pressure piece 5 and the top of the sealing packing 1, respectively, so that the upper pressure piece 5 will not directly contact the upper end surface of the sealing packing 1 during the rotation and extrusion of the sealing packing 1, thereby reducing the wear on the sealing packing 1 during the downward rotation and extrusion of the sealing packing 1 by the upper pressure piece 5.

[0021] The following is a detailed introduction to the actual working scenario of the electric test environmental protection plug.

[0022] like Figure 1 As shown, in actual work, when the electric test environmental protection plug is used, first, the opening of the driven gear 6 is placed in the logging wire, the driven gear 6 is docked and fixed with the upper pressure piece 5, and the drive motor 8 is installed on one side of the column 3 through the motor fixing frame, and the driving gear 7 and the driven gear 6 are meshed with each other.

[0023] After the driving motor 8 is connected to the ground power supply, the control device placed on the ground is used to control the positive and negative poles of the power supply of the electric test environmental protection plug to be turned on, so as to realize the forward and reverse rotation of the driving motor 8 on the ground. When the driving motor 8 rotates clockwise to drive the driving gear 7 to rotate, the driving gear 7 drives the driven gear 6 to rotate, and the driven gear 6 drives the upper pressure piece 5 to rotate. The upper pressure piece 5 rotates along the thread and moves vertically downward at the same time. The bottom of the upper pressure piece 5 squeezes the sealing packing 1 made of elastic material, so that the sealing packing 1 in the overflow channel 2 is squeezed and expanded to achieve the control The purpose of controlling the overflow flow rate; when it is necessary to increase the external overflow flow rate, the positive and negative poles of the driving motor 8 of the electric test environmental protection plug are controlled by the ground control device, so that the driving motor 8 rotates counterclockwise to drive the active gear 7 to rotate, the active gear 7 drives the driven gear 6 to rotate, and the driven gear 6 drives the upper pressure piece 5 to rotate, the upper pressure piece 5 rotates along the thread and moves vertically upward at the same time, and the bottom of the upper pressure piece 5 is away from the sealing packing 1 made of elastic material, reducing the degree of extrusion of the sealing packing 1 in the overflow channel 2, so that the sealing degree is reduced and the overflow flow rate is increased.

[0024] In actual work, in order to reduce the wear of the sealing packing 1 caused by the rotation of the upper pressure piece 5 during the operation of the electric test environmental protection plug, a fixed piece and a rotating piece can be set in the device, and the fixed piece can be detachably fixed on the top of the sealing packing 1, and the rotating piece is rotatably connected to the fixed piece, and the rotating piece is fixedly set at the bottom of the upper pressure piece 5, and the fixed piece is connected to the rotating piece, replacing the upper pressure piece 5 to directly contact the sealing packing 1; a bearing can also be set in the device, and the two parts of the bearing are respectively connected to the bottom end of the upper pressure piece 5 and the top of the sealing packing 1, replacing the upper pressure piece 5 to directly contact the sealing packing 1.
