[0024] like Figure 1 、 3 As shown in FIG9 , the adjustable shallow-sea and deep-sea multifunctional geological exploration node connector of the present invention comprises a fiber rope 1 and at least one node hook 2. The fiber rope 1 passes through the node hook 2 and is fixed thereto. Each node hook 2 comprises a hook sleeve 21, a left end sleeve 22, a right end sleeve 23, a left wedge plug 24, and a right wedge plug 25. The upper portion of the hook sleeve 21 is provided with a hook groove 211, and the lower portion of the hook sleeve 21 is provided with a through hole 212 (see FIG9 ). Figure 4 、 8), the center of the left end sleeve 22 is provided with a center through hole 1 221 along its axial direction, and the center of the right end sleeve 23 is provided with a center through hole 231 along its axial direction. The right end portion of the fiber rope 1 passes through the left end sleeve 22, the hanging sleeve 21, and the right end sleeve 23 in sequence. The left end sleeve 22 and the right end sleeve 23 are respectively threadedly connected to the two ends of the lower part of the hanging sleeve 21. The left wedge plug 24 and the right wedge plug 25 are rugby-shaped. The left wedge plug 24 and the right wedge plug 25 pass through the rope core of the fiber rope 1 and fix the fiber rope 1 to the node hanger 2. The left wedge plug 24 is located between the hanging sleeve 21 and the left end sleeve 22, and the right wedge plug 25 is located between the hanging sleeve 21 and the right end sleeve 23. Figure 9 As shown, the axes of the left wedge plug 24 and the right wedge plug 25 are perpendicular to the axis of the rope core of the fiber rope and the through hole 212.

[0025] like Figure 8 As shown, the through hole 212 is formed by connecting the left screw hole 2121, the middle screw hole 2122, and the right screw hole 2123 in sequence. The diameters of the left screw hole 2121 and the right screw hole 2123 are larger than the diameter of the middle hole 2122.

[0026] like Figure 6 As shown, the central through hole 221 includes a cylindrical hole 2211 and a tapered hole 2212. The right end of the cylindrical hole 2211 is connected to the small diameter end of the tapered hole 2212. Figure 9 As shown, the second central through hole 231 includes a second cylindrical hole 2311 and a second tapered hole 2312, and the left end of the second cylindrical hole 2311 is connected to the small diameter end of the second tapered hole 2312. Figure 9 As shown, the diameter of the cylindrical hole 1 2211 and the diameter of the cylindrical hole 2311 are both smaller than the diameter of the middle hole 2122. The diameter of the cylindrical hole 1 2211 and the diameter of the cylindrical hole 2311 are equal.

[0027] like Figure 6 、 7 As shown in Figures 9 and 9, the short diameter L1 of the cross section of the left wedge plug 24 and the right wedge plug 25 is larger than the diameter L2 of the cylindrical hole 1 2211 and smaller than the maximum diameter L3 of the tapered hole 1 2212. The maximum diameter L3 of the tapered hole 2312 is not shown in the figure.

[0028] When the left wedge plug 24 and the right wedge plug 25 fix the fiber rope 1 to the node hook 2, the left wedge plug 24 and the right wedge plug 25 are both located in the through hole 212 and cannot be pulled out, and the fiber rope 1 is squeezed and fixed between the hook sleeve 21 and the left end sleeve 22 and the right end sleeve 23.

[0029] like Figure 2 、 5As shown in Figures 6 and 9, the middle outer surface of the left end sleeve 22 is provided with a rotation-stopping protrusion 222, and the middle outer surface of the right end sleeve 23 is provided with a rotation-stopping protrusion 232. The rotation-stopping protrusion 222 of the left end sleeve 22 contacts and abuts against the left end surface of the hanging sleeve 21, and the rotation-stopping protrusion 232 of the right end sleeve 23 contacts and abuts against the right end surface of the hanging sleeve 21.

[0030] The node hitch 2 has a symmetrical structure. The left end sleeve 22 and the right end sleeve 23 are symmetrically arranged relative to the hitch sleeve 21. The left wedge plug 24 and the right wedge plug 25 have the same structure. The hitch sleeve 21, the left end sleeve 22, and the right end sleeve 23 are made of 316L.

[0031] like Figure 9 As shown, the adjustable shallow-sea and deep-sea multifunctional geological exploration node connector of the present invention fixes the node hook 2 on the fiber rope 1 through a wedge plug. The node hook 2 can be installed and adjusted at any position on the fiber rope 1. During installation, first unscrew the left end sleeve 22, the right end sleeve 23 and the hanging sleeve 21, and pass the fiber rope 1 through the middle of the node hook 2 (the fiber rope 1 passes through the center through hole 1 221 of the left end sleeve 22, the through hole 212 of the hanging sleeve 21, and the center through hole 231 of the right end sleeve 23 in sequence). Then, install the left wedge plug 24 in the left end sleeve 22 so that the left wedge plug 24 passes vertically through the fiber rope 1. Install the right wedge plug 25 in the right end sleeve 23 so that the right wedge plug 25 passes vertically through the fiber rope 1. When the fiber rope 1 is passed and the connector 2 is placed at the position where it needs to be connected, the left end sleeve 22 and the left wedge plug 24 are pushed toward the connector sleeve 21, and the right end sleeve 23 and the right wedge plug 25 are pushed toward the connector sleeve 21. The left end sleeve 22 and the right end sleeve 23 are screwed together with the connector sleeve 21 to tighten them. The node connector 2 is fixed to the fiber rope 1. Then, the marine geological exploration equipment is hooked to the hooking groove 211 to achieve the connection and traction of the marine geological exploration equipment. When the position needs to be adjusted, the left end sleeve 22, the right end sleeve 23 and the connector sleeve 21 are unscrewed to slide the node connector 2 as a whole along the fiber rope 1 to the desired position. Then, the left end sleeve 22, the right end sleeve 23 and the connector sleeve 21 are screwed together to tighten them according to the above method to fix the node connector 2.

[0032] The adjustable shallow-water and deep-sea multifunctional geological exploration node connector of the present invention serves as a connection and traction device for shallow-water and deep-sea marine geological exploration equipment. The node positions and spacing are adjustable, allowing for simultaneous use of multiple projects. The length of the fiber rope 1 is determined based on actual needs, and the number of node connectors 2 is determined based on the length of the fiber rope 1 and the number of exploration equipment.

[0033] The adjustable shallow-sea and deep-sea multifunctional geological exploration node connector of the present invention is easy to use; the node hook can be detached from the fiber rope and can be adjusted to any position of the fiber rope at any time, realizing repeated use and adjustment of the node hooking position. When multiple node hooks are used, the distance between nodes can be adjusted at any time according to the geographical environment (such as Figure 1 Two node connectors are shown in the figure, and the distance between the two nodes can be adjusted), which provides favorable protection for shallow and deep sea marine geological exploration.

[0034] The embodiments described above are merely descriptions of preferred implementations of the present invention and are not intended to limit the scope of the present invention. Without departing from the spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the scope of protection determined by the claims of the present invention.
