[0002] Currently, most wellhead cable guide devices on the market are column bracket type, which include a column bracket and a wire pulley at the top of the column bracket, wherein the column bracket is used to support the detection object, the wire pulley and other devices, and the wire pulley realizes the guiding function of the detection object and the cable. During installation, the operator fixes the column bracket on the wellhead flange with a mounting hole, and then passes the cable of the detection object around the wire pulley at the top of the column bracket, thereby suspending it below the guide wheel and extending it into the wellhead, thereby performing corresponding inspection operations on the gas storage well pipeline. Existing wellhead cable guide devices have high requirements for on-site space, and their column brackets are generally telescopic, with relatively complex structure and high cost. In addition, the one-piece column bracket makes it inconvenient for operators to transport and install it.

DETAILED DESCRIPTION

[0023] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0024] See also Figures 1 to 7 A wellhead cable guide device according to a preferred embodiment of the present invention includes an adapter plate 1, a diagonal support plate 2 provided on the adapter plate, and a guide wheel 3 rotatably provided on the diagonal support plate. A transmission hole 4 penetrating the adapter plate is provided on the surface of the adapter plate. One end of the diagonal support plate is detachably provided on the adapter plate. The guide wheel is rotatably provided on the end of the diagonal support plate through a hinge shaft, and the guide wheel is located directly above the transmission hole.

[0025] The wellhead cable guide device of the present invention realizes the guiding function of the detection body through the arrangement of the diagonal support plate and the guide wheel. Compared with the existing wellhead cable guide device, its structure is simpler. In addition, since the diagonal support plate is arranged obliquely, it has a certain angle with the surface of the adapter plate, thereby reducing the overall volume of the wellhead cable guide device. At the same time, the split design of each component also makes it easy for the operator to carry and transport the wellhead cable guide device. When in use, the operator first fixes the adapter plate to the flange plate 5 of the wellhead and makes the transmission hole on its surface face the wellhead. Then, the operator winds the cable of the detection body around the guide wheel and passes the detection body through the transmission port and the wellhead in turn and extends it into the well, thereby performing detection operations on the pipeline in the well. One end of the diagonal support plate, preferably the bottom end, can be detachably connected to the lug 6 set on the edge of the adapter plate by bolts or other connecting parts.

[0026] Preferably, in the wellhead cable guide device of the present invention, a mounting hole 7 is provided on the surface of the adapter plate.

[0027] The installation of the mounting holes facilitates the operator to install the adapter plate on the flange plate of the wellhead. In practice, the mounting holes are multiple rectangular holes arranged around the periphery of the transmission hole. The rectangular mounting holes facilitate the operator to align the adapter plate with the flange plate.

[0028] Preferably, the wellhead cable guide device of the present invention comprises a diagonal support plate including a vertical plate 8 whose bottom end is arranged on the surface of the adapter plate, an inclined plate 9 whose bottom end is connected to the vertical plate and whose plate body is arranged obliquely, and a guide wheel is arranged at the top of the inclined plate.

[0029] This design specifically implements a diagonal support plate, in which the vertical plate is arranged vertically, and its side surface is perpendicular to the surface of the adapter plate. The plate body of the diagonal plate is intersecting with the adapter plate. Specifically, the two side surfaces of the diagonal plate are parallel to each other and intersect with the surface of the adapter plate.

[0030] Preferably, in the wellhead cable guiding device of the present invention, the surface of the adapter plate is provided with a positioning frame 10 fixedly connected to the adapter plate, the positioning frame includes an upper positioning plate 11 and a lower positioning plate 12 located below the upper positioning plate, and a connecting column 13 with an end fixedly connected to the diagonal support plate is provided between the upper positioning plate and the lower positioning plate, and limiting members 14 connected to the positioning frame are respectively provided on both sides of the connecting column.

[0031] The setting of the positioning frame and the connecting column realizes the purpose of detachably setting the diagonal support plate on the adapter plate. The limiting members on both sides of the connecting column realize the limiting effect on the diagonal support plate, so that the operator can adjust the position of the wire wheel by adjusting the position of the connecting column in the positioning frame to achieve the purpose of positioning the detection body at the center of the wellhead. One of the limiting members can be formed by a connecting plate 15 connecting the upper positioning plate and the lower positioning plate, and the upper positioning plate, the lower positioning plate and the connecting plate can be formed as one piece. The other positioning member can be realized by setting a positioning pin on the other side of the connecting column. Other similar methods can also be used to form the limiting member, which will not be repeated here. The positioning frame can be directly fixed to the adapter plate by bolts.

[0032] Preferably, in the wellhead cable guide device of the present invention, the positioning frame further comprises a connecting plate 15 connecting the upper positioning plate and the lower positioning plate, and the connecting plate forms one of the two limiting members on both sides of the connecting column.

[0033] Preferably, the wellhead cable guide device of the present invention is further provided with a limit pin assembly on the positioning frame, the limit pin assembly includes a column 16 and a limit pin 17 provided at the bottom end of the column, the limit pin forms another limit piece of the two limit pieces on both sides of the connecting rod, and the upper positioning plate and the lower positioning plate are correspondingly provided with positioning holes 18 adapted to the limit pin.

[0034] The positioning pin assembly limits the position of the connecting column. During use, the operator inserts the connecting column between the upper and lower positioning plates through the opening on one side of the positioning frame. The operator then inserts the bottom end of the limiting pin into the positioning holes on the upper and lower positioning plates, respectively. The connecting column is now positioned between the connecting plate and the limiting pin. The operator can move the connecting column between the connecting plate and the limiting pin to adjust the position of the diagonal support plate and the guide pulley. Furthermore, positioning holes can also be provided on the adapter plate, into which the bottom end of the limiting pin can be directly inserted.

[0035] Preferably, in the wellhead cable guide device of the present invention, the number of the diagonal support plates and the number of the positioning frames are both two, and the two ends of the connecting column are respectively fixed on the diagonal support plates on both sides.

[0036] The arrangement of the two diagonal bracing plates and the two positioning frames makes the overall strength of the diagonal bracing plates higher and the structure more stable.
