[0037] As shown in Figures 1 to 10 A tensile chain type flexible sensor device, comprising a plurality of sensors 1, each of which is provided with a sensor joint 11;

[0038] A plurality of cables 2, each of which is provided with a cable joint 21, any two adjacent sensors 1 are connected by the cable 2, and the cable joint 21 is rotatably inserted in the sensor joint 11;

[0039] A locking structure 3 is rotatably arranged on each cable 2, and the locking structure 3 is used to lock the sensor joint 11 and the cable joint 21 after rotating in a first direction, and the locking structure 3 is unlocked for the sensor joint 11 and the cable joint 21 after rotating in a second direction opposite to the first direction.

[0040] The present application provides a tensile chain type flexible sensor device, which is connected end to end by a plurality of sensors 1 and a plurality of cables 2, and is fixed by sensor joint 11 and cable joint 21 to form a flexible chain structure. The device can be placed vertically in the stratum or water, and can realize multi-parameter data acquisition by integrating various types of sensors 1 at each node, and can monitor displacement, attitude and other information, and can collect stratum change data for a long time, and can also collect hydrological data in water for a long time.

[0041] In particular, the present application also provides a locking structure 3, each sensor 1 is provided with the locking structure 3, due to the existence of the locking structure 3, when the locking structure 3 rotates in the first direction (such as clockwise direction), the sensor joint 11 and the cable joint 21 are in the locked state, when the locking structure 3 rotates in the second direction (such as counterclockwise direction), the sensor joint 11 and the cable joint 21 are unlocked. In this way, it can be ensured that the connection position of the cable 2 and the sensor 1 is in a stable locking state during use, and only when the locking structure 3 is rotated under the action of external force, the two can be unlocked, so that the sensor 1 can realize long-term stable monitoring.

[0042] Furthermore, the locking structure 3 includes a rotating locking ring 31 sleeved on the outside of the cable 2, and there is an insertion gap 311 between the inner wall of the bottom end of the rotating locking ring 31 and the outer wall of the cable 2, and the top end of the sensor connector 11 is inserted into the insertion gap 311.

[0043] The rotary locking ring 31 has at least one locking groove 312, and the top end of the sensor connector 11 has at least one locking post 111. The locking post 111 corresponds one-to-one with the locking groove 312. The rotary locking ring 31 is used to make the locking post 111 slide into the locking groove 312 and lock it after rotating in the first direction, so as to lock the sensor connector 11 and the cable connector 21. After rotating in the second direction, the rotary locking ring 31 makes the locking post 111 disengage from the locking groove 312 to unlock the sensor connector 11 and the cable connector 21.

[0044] like Figures 5 to 7 As shown, when the sensor connector 11 and cable connector 21 need to be locked, the cable connector 21 is first inserted into the hollow part inside the housing of the sensor connector 11 to connect with it. Then, the rotating locking ring 31 is rotated clockwise until the opening end of the locking groove 312 of the rotating locking ring 31 corresponds to the locking post 111 on the sensor connector 11. The rotating locking ring 31 is then rotated clockwise again, and the locking post 111 slides from the opening end of the locking groove 312 into the engagement position 3121 within the locking groove 312, firmly locking itself in the engagement position 3121, thus locking the cable connector 21 and the sensor connector 11 in a stable connection. When it is necessary to separate the cable 2 and the sensor 1, rotating the rotating locking ring 31 in the opposite direction will disengage the locking post 111 from the engagement position 3121 of the locking groove 312.

[0045] In this embodiment, both the locking groove 312 and the corresponding locking pin 111 can be set to two. In other embodiments, the locking groove 312 and the corresponding locking pin 111 can also be set to one, three or more, which can be adjusted adaptively in different situations.

[0046] Furthermore, the locking structure 3 also includes a crimping ring seat 32 and a first elastic element 33. The crimping ring seat 32 is sleeved on the outer wall of the top end of the rotating locking ring 31. The outer edge of the top end of the rotating locking ring 31 is also provided with at least one protrusion 313. At least one limiting part 321 is provided in the crimping ring seat 32. The protrusion 313 corresponds one-to-one with the limiting part 321, and there is an installation space between the corresponding protrusion 313 and the limiting part 321. The first elastic element 33 is provided in the installation space. The two ends of the first elastic element 33 abut against the limiting part 321 and the protrusion 313 respectively.

[0047] As Figures 5 to 8 shown, in order to ensure that the locking column 111 is firmly clamped in the clamping position 3121 of the locking groove 312, the embodiment also provides a crimp ring seat 32 and a first elastic member 33. The crimp ring seat 32 is fixed together with the cable 2, and the rotating lock ring 31 is nested with the crimp ring seat 32. Since the crimp ring seat 32 is provided with a limiting portion 321, the rotating lock ring 31 is provided with a corresponding protruding portion 313. Each set of corresponding limiting portion 321 and protruding portion 313 leaves an installation space therebetween. The first elastic member 33 in the installation space has two ends respectively abutting against the limiting portion 321 and the protruding portion 313. That is, due to the pushing force of the first elastic member 33, the rotating lock ring 31 always has a tendency to rotate in one direction relative to the crimp ring seat 32. When the rotating lock ring 31 is rotated, the locking column 111 continuously slides along the inclined surface of the opening end of the locking groove 312. The locking column 111 first slides along a section of the inclined surface, and then slides along a section of the vertical surface. When the locking column 111 passes over the top end of the vertical surface and is located at the empty position of the locking groove 312, the rotating lock ring 31 will rebound (i.e. reverse rotation) under the action of the first elastic member 33, so that the protruding portion 313 is stably clamped in the clamping position 3121 of the locking groove 312, and the connection is completed. The above-mentioned first elastic member 33 has a rotating reset effect. The limiting portion 321 and the protruding portion 313 are in contact with each other, so that the rotating lock ring 31 can basically only rotate in the clockwise direction, and the reset will not exceed the predetermined position.

[0048] When it is necessary to separate the cable 2 and the sensor 1, the rotating lock ring 31 needs to be manually rotated to overcome the pushing force of the first elastic member 33, so that the locking column 111 is detached from the clamping position 3121 of the locking groove 312. Generally, the clamping position 3121 is provided in the form of a circular arc that fits the outer end surface of the protruding portion 313.

[0049] Further, the cable 2 comprises an inner core 22, a metal mesh layer 23 and a rubber layer 24 arranged in sequence from inside to outside.

[0050] As Figure 3 and Figure 9 shown, compared with the traditional structure of the sensor 1, the cable 2 and the cable joint 21 part of the present scheme are reinforced. Specifically, the outermost layer of the cable 2 structure of the present scheme is the rubber layer 24 to protect the internal metal mesh layer 23. The metal mesh layer 23 is additionally arranged outside the inner core 22 of the cable 2, so that the tensile chain type flexible sensor device not only has the flexibility, but also has good tensile performance. When the device is subjected to the traction of external force, the metal mesh layer 23 inside the cable 2 bears the action force, that is, the stress of the overall structure is borne by the metal part, instead of the general cable 2 rubber structure, thereby improving the overall strength of the tensile chain type flexible sensor device.

[0051] Further, a crimping outer ring 4 is sleeved outside the crimping ring seat 32, an installation gap is formed between the inner wall of the crimping outer ring 4 and the outer wall of the crimping ring seat 32, the end of the metal mesh layer 23 is inserted into the installation gap, and the end of the rubber layer 24 is inserted into the top end of the crimping outer ring 4.

[0052] As shown in Figure 3 and Figure 9 , the end of the rubber layer 24 is connected with the crimping outer ring 4, the end of the metal mesh layer 23 extends out of the cable 2 and enters into the installation gap, and is clamped between the crimping ring seat 32 and the crimping outer ring 4. When the cable joint 21 is manufactured, the metal mesh layer 23 is clamped in the center of the crimping ring seat 32 and the crimping outer ring 4 by the method of external pressure forming, so that the crimping outer ring 4, the crimping ring seat 32 and the metal mesh layer 23 form a whole force body of a metal structure. When the cable 2 is pulled, the metal mesh layer 23 is first stressed, the external force is transmitted to the rotating lock ring 31, and then to the shell of the sensor joint 11, so as to ensure the overall strength of the device.

[0053] Further, the crimping ring seat 32 is provided with a first stepped portion 322 and a second stepped portion 323, the second stepped portion 323 is located above the first stepped portion 322, the top end of the rotating lock ring 31 is connected to the first stepped portion 322, and the second stepped portion 323 is provided with an isolation pad 25, and the isolation pad 25 is sleeved outside the inner core 22.

[0054] The second stepped portion 323 is further provided with a second elastic member 26, the second elastic member 26 is sleeved outside the inner core 22, the isolation pad 25 is located on the inner side of the metal mesh layer 23, and the second elastic member 26 is located on the inner side of the isolation pad 25.

[0055] In the embodiment, the top end of the rotating lock ring 31 is clamped in the first stepped portion 322 of the crimping ring seat 32. The crimping ring seat 32 is further provided with a second stepped portion 323, the second stepped portion 323 is provided with a vertical second elastic member 26 and an isolation pad 25, so that the rotating lock ring 31 has a certain axial movement space, and the metal mesh layer 23 is isolated by the isolation pad 25, so as to ensure the flexible movement of the rotating lock ring 31.

[0056] Further, the inner core 22 comprises a filling layer 221, a shielding layer 222 and a protective isolation layer 223 arranged in sequence from inside to outside, and a plurality of conductive copper cores 224 are arranged in the filling layer 221.

[0057] The cable 2 in the embodiment has a multi-layer structure, in addition to the metal mesh layer 23 and the rubber layer 24, the inner core 22 of the cable 2 further comprises a filling layer 221, a shielding layer 222 and a protective isolation layer 223 at the outermost layer, a plurality of conductive copper cores 224 can be arranged in the filling layer 221, and the protective isolation layer 223 can isolate the inner core 22 from the metal mesh layer 23, so that the metal mesh layer 23 will not damage the internal structure under stress.

[0058] In actual production, the filling layer 221 can be a flame-retardant net cotton yarn or a PP rope, the shielding layer 222 can be an aluminum strip, a bare copper wire, a copper-coated steel wire or a tinned copper wire, and the protective isolation layer 223 can be a polyester strip.

[0059] Further, the outer wall of the crimping outer ring 4 is further sleeved with an outer lock cap 5, the outer lock cap 5 is sleeved with the locking structure 3, the cable 2 and the cable joint 21, and the bottom end of the outer lock cap 5 is threadedly connected with the outer wall of the sensor joint 11. After the cable joint 21 and the sensor joint 11 are connected in a plug-in manner, the outer lock cap 5 is threadedly connected with the sensor joint 11, and the connecting structure is further reinforced.

[0060] When the threaded connection fails, the connection between the rotating lock ring 31 and the locking column 111 of the sensor joint 11 can also ensure that the two are not loosened under traction, thereby ensuring the reliability of the circuit connection.

[0061] Further, the shell of the sensor joint 11 is made of metal. In addition to the crimping outer ring 4, the crimping ring seat 32 and the metal mesh layer 23 forming a whole force body of the metal structure, the shell of the sensor joint 11 is also made of metal in the scheme, so that when the device is vertically laid in the stratum or the ocean, it can deform freely with the change of the surrounding geology or ocean current. When a larger external force is applied, the metal structure can effectively prevent the tensile chain type flexible sensor device from being pulled off, and the structural integrity of the device can be maintained after a long period of work, thereby effectively prolonging the service life of the device, improving the operation stability and reducing the cost.

[0062] Further, the first elastic member 33 and the second elastic member 26 are both springs. When the spring is used as the first elastic member 33 or the second elastic member 26, it has a long service life and can maintain an expanded state under no external force and can be compressed under external force, so that the locking structure 3 has a good locking effect.

[0063] The above only describes preferred embodiments of the utility model, and does not limit the patent range of the utility model, and any equivalent structural transformation made under the inventive concept of the utility model, or direct / indirect application in other related technical fields is included in the patent protection range of the utility model.
