[0021] In the description of this utility model, it should be understood that if there are descriptions involving orientation, such as up, down, front, back, left, right, etc., indicating orientation or positional relationship, the orientation description may be based on the orientation or positional relationship shown in the accompanying drawings. This is only for the convenience of describing this utility model and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.

[0022] In the description of this utility model, if there is a description of quantity, "several" means one or more, "more than" means two or more, "greater than," "less than," "exceeding," etc. are understood to exclude the number itself, while "above," "below," "within," etc. are understood to include the number itself. If there is a description of "first" or "second," it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of indicated technical features or the order of the indicated technical features.

[0023] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0024] like Figures 1 to 5 As shown, this utility model discloses a deep well detection device with stable cable routing, including a main support 1, a winding reel 2, a cable, a telescopic arm 3, a drive mechanism 4, and a reciprocating bracket mechanism 5. The winding reel 2 is hinged at both ends to the main support 1. The lower end of the telescopic arm 3 is installed at one lower end of the main support 1, and a counter 11 is provided at the upper end of the telescopic arm 3. The drive mechanism 4 includes a drive motor 204 fixed to the main support 1 below the winding reel 2 and a first transmission mechanism located at one end of the winding reel 2 and connected to the output end of the drive motor 204. The drive motor 204 can drive the winding reel 2 to rotate through the first transmission mechanism. The reciprocating bracket mechanism 5 includes two bracket bearing seats 501, a lead screw 502, a guide shaft 503, and a guide slider 504. The lead screw 502 and the guide shaft 503 are installed parallel to each other between the two bracket bearing seats 501. The guide slider 504 is provided with a guide sleeve 511 adapted to the guide shaft 503 and a guide sleeve 511 adapted to the lead screw 502. A translational sleeve 510 is adapted to and can move with the rotation of the lead screw 502. The two bracket bearing seats 501 are fixed on the main support 1 between the winding reel 2 and the telescopic arm 3. A second transmission mechanism is provided between the other end of the winding reel 2 and the lead screw 502. The upper end of the guide slider 504 is also provided with a guide roller assembly for multi-directional limiting and guiding of the cable. When the winding reel 2 rotates, it can drive the lead screw 502 to rotate through the second transmission mechanism, thereby driving the guide slider 504 to move. This can ensure smoothness and flatness of the cable when the deep well detection device is laying or retracting the cable. The cable is wound on the winding reel 2 and one end passes through the guide roller assembly and the counter 11 in sequence. The guide roller assembly can limit the cable in multiple directions. The counter 11 can record the length of the cable laid. The instrument is set on the telescopic arm 3. The telescopic arm 3 can swing up and down according to the distance between the well and the detection device to facilitate adaptation to wellhead positions at different distances.

[0025] In this utility model, the main support 1 is provided with two oppositely arranged wire reel bearing seats 201. The winding reel 2 has a left wire reel shaft 202 and a right wire reel shaft 203 at both ends, respectively adapted to the two wire reel bearing seats 201. The drive motor 204 is provided with a drive gear. The first transmission mechanism includes a first transmission gear 205, a first rotating clutch seat 206, an isolation bearing 207, a compression spring 208, and a first transmission chain 209. The left wire reel shaft 202 is provided with an axially arranged first strip-shaped sliding hole 215. The first transmission gear 205 and the first rotating clutch seat 206 are both sleeved on the left wire reel shaft 202, and the first rotating clutch seat 206 has a first linkage pin 210 on the side near the first transmission gear 205. The first transmission gear 205 has a linkage pin 210 on the side near the first rotating clutch seat 206. The first linkage socket 211 is adapted to the first rotating clutch seat 206. The first connecting bolt 216 is radially inserted and passes through the first strip-shaped sliding hole 215. The isolation bearing 207 and the compression spring 208 are both disposed between the first transmission gear 205 and the first rotating clutch seat 206. The isolation bearing 207 is in contact with the first transmission gear 205. The two ends of the compression spring 208 are respectively in contact with the first rotating clutch seat 206 and the isolation bearing 207. The first transmission gear 205 is clearance-fitted with the left coil shaft 202. The first transmission chain 209 is sleeved on the first transmission gear 205 and the drive gear. The free end of the left coil shaft 202 is axially provided with an adjusting bolt 218 that can be laterally supported on the middle of the first connecting bolt 216. The free end of the left coil shaft 202 is provided with a wrench rotating part 217. When the adjusting bolt 218 is tightened, it will laterally press against the middle of the first connecting bolt 216. At this time, the first rotary clutch seat 206 will compress the compression spring 208 so that it is in contact with the first transmission gear 205. The first linkage pin 210 will be inserted into the first linkage hole 211, so that the first rotary clutch seat 206 can rotate synchronously with the first transmission gear 205. Then the first transmission gear 205 can drive the winding reel 2 to rotate. When the adjusting bolt 218 is loosened, the first rotary clutch seat 206 will separate from the first transmission gear 205 under the action of the compression spring 208. At this time, the winding reel 2 will not rotate synchronously with the first transmission gear 205.

[0026] In existing detection devices, the drive motor 204 will lock itself and cannot rotate after an unexpected power outage. This also prevents the winding reel 2 connected to the drive motor 204 from rotating, making it impossible to retract the external cable. In this invention, the adjusting bolt 218 can be loosened first, so that the winding reel 2 does not rotate synchronously with the first transmission gear 205. By rotating the wrench rotating part 217, the winding reel 2 can be driven to rotate, and the cable can be wound up. Even if there is an unexpected power outage, the cable winding or unwinding operation can still be performed.

[0027] In this utility model, the second transmission mechanism includes a second transmission gear 212, a speed-changing gear set 213, and a second transmission chain 214. The reciprocating bracket mechanism 5 further includes a third transmission gear 505, a second rotary clutch seat 506, and a manual adjustment rod 507. The second transmission gear 212 is sleeved on the right reel shaft 203 and can rotate synchronously. The second transmission gear 212 meshes with the input end of the speed-changing gear set 213. One end of the lead screw 502 is provided with an axially arranged second strip-shaped sliding hole 517. The second rotary clutch seat 506 and the third transmission gear 505 are sequentially sleeved on the end of the lead screw 502 with the strip-shaped sliding hole, and the second rotary clutch seat 506 is close to the input end of the lead screw 502. A second linkage pin is provided on one side of the third transmission gear 505. A second linkage insertion hole adapted to the second linkage pin is provided on the side of the third transmission gear 505 near the second rotary clutch seat 506. A second connecting bolt 518 is provided in the second rotary clutch seat 506, which is radially inserted and passes through the second strip-shaped sliding hole 517. The end face of the lead screw 502 with the second strip-shaped sliding hole 517 is also provided with a connecting hole communicating with the second strip-shaped sliding hole 517. One end of the manual adjustment rod 507 passes through the connecting hole and is connected to the second connecting bolt 518. The second transmission chain 214 is sleeved on the output end of the third transmission gear 505 and the gear set 213. By setting the second strip-shaped sliding hole 517, the manual adjustment rod 507 can drive the second rotary clutch seat 506 to move back and forth. It can also drive the lead screw 502 to rotate. During normal operation, the second linkage pin of the second rotary clutch seat 506 is inserted into the third transmission gear 505, so that they can rotate synchronously. In this way, when the third transmission gear 505 rotates, the lead screw 502 can be driven to rotate through the second rotary clutch seat 506. When it is necessary to adjust the position of the guide slider 504, the manual adjustment rod 507 can be pressed first to separate the second rotary clutch seat 506 from the third transmission gear 505. At this time, the third rotary gear will not rotate synchronously with the second rotary clutch seat 506. In this way, the position of the guide slider 504 can be adjusted directly by manually rotating the lead screw 502.
