[0044] In one embodiment of the present invention, see Figure 3-Figure 6 , the number of the long ejector guide sleeve 9 and the short ejector guide sleeve 13 are both two, the number of the guide sleeve 34 and the guide column 35 are both four, wherein two of the guide sleeves 34 are fixedly mounted on the left side plate 2, and the other two of the guide sleeves 34 are fixedly mounted on the left side small plate 12;

[0046] The number of the long boosting rod 6 and the short boosting rod 15 are both two, and the number of the boosting rod seat 16 and the boosting rod shaft 17 are both four.

[0047] In one embodiment of the present invention, see Figure 5 The wheel train components include a small wheel shaft 20, a small wheel 21, a small wheel bearing 23, a large wheel 27, a brake pad 28, a brake disc 29, a large wheel bearing 30 and a large wheel sleeve 31;

[0048] The brake pad 28 is fixedly mounted on the large wheel 27 and connected to the brake disc 29. The small wheel bearing 23 is fixedly mounted on the left side plate 2 and the right side plate 10, and the small wheel shaft 20 is rotatably mounted in the small wheel bearing 23.

The two ends of the large wheel sleeve 31 are fixedly mounted on the left side plate 2 and the right side plate 10, respectively.

[0049] The small wheel 21 and the large wheel 27 are both provided with winding grooves, and the large wheel 27 is also provided with a plurality of through holes evenly distributed circumferentially, and the through holes are detachably connected to the guide posts 35. The large wheel 27 is provided with through holes evenly distributed circumferentially to allow the guide posts to be inserted into the large wheel 27 to completely lock it.

[0050] See also Figure 5 The number of the small wheel bearing 23, the brake disc 29 and the large wheel bearing 30 is two, and the number of the brake pad 28 is four.

[0051] In one embodiment of the present invention, see Figure 4 and Figure 5 The control component includes a circuit control box 11, a magnet 22 and an induction coil 24. The circuit control box 11 is fixedly mounted on the transmission component. There are eight magnets 22, all of which are fixedly mounted on the small wheel 21. When the rope release speed accuracy is higher, the number of magnets 22 can be increased.

[0052] The induction coil 24 is fixedly mounted on the right side plate 10 and is connected to the circuit control box 11 via a wire;

[0053] The circuit control box 11 can detect the rotation speed and number of revolutions of the small wheel 21 through the induction coil 24 .

[0054] In one embodiment of the present invention, see Figure 5 The transmission component includes a transmission nut 19, a transmission shaft 25 and a motor 26. The motor 26 is connected to the right side plate 10 and the circuit control box 11. The transmission nut 19 is fixedly mounted on the brake plate 4. The two ends of the transmission shaft 25 are respectively connected to the transmission nut 19 and the motor 26.

[0055] The rotation of the motor 26 drives the transmission shaft 25 to rotate, and the forward and reverse rotation of the transmission shaft 25 drives the transmission nut 19 to perform linear reciprocating motion. The motor 26 is connected to the circuit control box 11 with a wire, and the circuit control box 11 can control the forward and reverse rotation and rotation speed of the motor 26.

[0056] In one embodiment of the present invention, see Figure 6 , further comprising: a wire guide sleeve 32 and a wire clamp 33, both of which are fixedly mounted on the base plate 1, the rope enters the release device through the wire guide sleeve 32 and passes through the wire clamp 33, and the clamping force of the wire clamp 33 can be adjusted as needed;

[0057] The outlet seat 36 is fixedly mounted on the left side plate 2 and is used to control the outlet position of the rope.

[0058] To sum up, when installing the rope, the rope is led out from a device such as a rope drum or rope roller, enters the release device from the wire guide sleeve 32, and then passes through the wire clamp 33 and is wound around the first winding groove of the large wheel 27, and then is wound from the large wheel 27 to the first winding groove of the small wheel 21, and then is wound from the small wheel 21 to the second winding groove of the large wheel 27, and this method is used until it is wound around the last winding groove of the small wheel 21, and finally passes through the lead-out device of the wire outlet seat, and the lead-out end is used to pull instruments and equipment.

[0059] Before using the device, the brake spring 8 is compressed to its shortest position. At this time, the guide post 35 is inserted into the through hole on the large wheel 27, completely locking it and preventing it from rotating. The resistance of the brake spring 8 is transmitted to the two long push rods 7 and the two short push rods 14 to the two long force rods 6 and the two short force rods 15. The two long force rods 6 and the two short force rods 15 amplify the spring resistance through the lever action and transmit it to the four force transmission adjustment rods 5. The long force rods 6 and the short force rods 15 have equal amplification ratios and are arranged symmetrically on both sides. The force transmission adjustment rods 5 can be fine-tuned to balance the forces on both sides of the large wheel 27.

[0060] The four force transmission adjustment rods 5 then transmit the spring resistance to the two brake discs 29 through the four brake rods 3. The two brake discs 29 on both sides of the large wheel 27 simultaneously press the four brake pads 28 (two pairs). At this time, the friction force on the large wheel 27 is the largest. When in use, the friction force can be adjusted by adjusting the resistance of the spring. The rotation speed of the large wheel 27, that is, the rope release speed, can be adjusted according to the friction force. The rope release speed is fed back to the circuit control box 11 through the combination of the magnet 22 and the induction coil 24. The circuit control box 11 can also calculate the length of the rope released.

[0061] When the release device is in use, the rope is introduced into the terminal rope storage device and is led out to the terminal instrument and equipment. The release speed of the instrument and equipment can be pre-set through the circuit control box 11, and the release speed can also be changed in real time. When the instrument and equipment start to release, the mass of the instrument and equipment is used to provide traction for the rope. The circuit control box 11 controls the motor 26 to rotate, driving the transmission shaft 25 to rotate. The transmission shaft 25 rotates in the spiral groove of the transmission nut 19 to make the transmission nut 19 do linear motion. The brake plate 4 gradually moves away from the left side plate 2. The brake plate 4 drives the guide column 35 to move under the guidance of the guide sleeve 34. The brake spring 8 gradually becomes longer and the resistance gradually decreases. When the guide When the post 35 leaves the through-hole of the large wheel 27, the locked state of the large wheel 27 is released; the motor 26 continues to rotate until the gravity of the instrument exceeds the friction force on the large wheel 27, and the large wheel 27 begins to rotate. When the rotation speed of the large wheel 27 reaches the set speed, the motor 26 stops. However, the friction force on the large wheel 27 is affected by many factors and is constantly changing. Therefore, the circuit control box 11 controls the forward or reverse rotation of the motor 26 based on the feedback of the rope release speed, dynamically adjusting the friction force on the large wheel 27, thereby maintaining the rotation speed of the large wheel 27 stable and causing the rope release speed to fluctuate slightly around the set speed. When the preset rope release length is approaching a certain range, the circuit control box 11 controls the rotation of the motor 26, causing the brake plate 4 to gradually approach the left side plate 2, gradually compressing the brake spring 8, gradually increasing the friction force on the large wheel 27, and gradually reducing the rotation speed of the large wheel 27 until the large wheel 27 reaches the preset rope release length and is completely stopped.

[0062] If the rope release device is used for releasing the depth-fixing equipment, the circuit control box 11 can receive the signal of the external water pressure sensor. At the beginning, the circuit control box 11 controls the motor 26 to rotate, so that the brake plate 4 moves away from the left side plate 2 until the resistance of the brake spring 8 is zero. At this time, the friction force on the large wheel 27 is the smallest, the rotation speed of the large wheel 27 is the fastest, and the rope release speed is the largest. When approaching a certain range of the preset depth, the circuit control box 11 controls the motor 26 to rotate, so that the brake plate 4 gradually approaches the left side plate 2, the brake spring 8 is gradually compressed, the friction force on the large wheel 27 gradually increases, and the rotation speed of the large wheel 27 gradually decreases until the large wheel 27 is completely stopped when the preset rope release length is reached.

[0063] If the rope release device is used to release underwater autonomous depth-fixing floating instruments and equipment, there is a heavy anchor at the bottom of such equipment. When in use, the heavy anchor is released by the rope release device, and the heavy anchor sinks, pulling the instrument and equipment down. The instrument and equipment itself has positive buoyancy. When the heavy anchor sinks to the seabed, the instrument and equipment itself can float at the preset depth. The circuit control box 11 of the rope release device can receive the signal of the external water pressure sensor. At the beginning, the circuit control box 11 controls the motor 26 to rotate, so that the brake plate 4 moves away from the left side plate 2 until the resistance of the brake spring 8 is zero. At this time, the friction force on the large wheel 27 is the smallest, the rotation speed of the large wheel 27 is the fastest, and the rope release speed is the largest. When the instrument and equipment sinks to a certain range close to the preset depth, the circuit control box 11 controls the motor 26 to rotate, so that the brake plate 4 gradually approaches the left side plate 2, the brake spring 8 is gradually compressed, the friction force on the large wheel 27 gradually increases, and the rotation speed of the large wheel 27 gradually decreases. Until it reaches the preset instrument and equipment release depth, the sinking speed of the heavy anchor is close to the speed of the rope release. Due to the influence of factors such as inertia, The depth of the instrument is in a changing state, which requires the circuit control box 11 to continuously detect the depth value fed back by the water pressure sensor, and control the size of the friction force on the large wheel 27 by changing the forward and reverse rotation of the motor 26, thereby controlling the rope release speed. When the detected depth value is greater than the preset depth value, the circuit control box 11 controls the motor 26 to rotate, so that the brake plate 4 moves away from the left side plate 2, reduces the resistance of the brake spring 8, and increases the rope release speed. When the detected depth value is less than the preset depth value, the circuit control box 11 controls the motor 26 to rotate, so that the brake plate 4 approaches the left side plate 2, increases the resistance of the brake spring 8, and reduces the rope release speed. Such repeated automatic control can keep the instrument near the preset depth until the heavy anchor sinks to the seabed. The circuit control box 11 controls the motor 26 to rotate at maximum speed, so that the brake plate 4 quickly approaches the left side plate 2, the brake spring 8 is quickly compressed, the friction force on the large wheel 27 increases rapidly, and the rotation speed of the large wheel 27 decreases rapidly until the large wheel 27 is completely stopped. At this time, the rope release work is completed.
