Description

Technical Field

[0001] The utility model relates to the field of underwater equipment, in particular to an underwater winch tension measuring device. Background Art

[0002] With the continuous improvement of my country's comprehensive national strength, scientific research investment in deep-sea exploration, development, and utilization has been increasing year by year in recent years. For some special deep-water applications, retractable winches are often used to release and recover detection array cables in deep water, so it is necessary to measure the tension of the array cable released from the winch.

[0003] Considering that underwater winch cable tension measurement is often performed through underwater tension sensors, but underwater tension sensors are often used to measure tension values greater than 500kg. For tension measurements of tension values less than 500kg, this type of sensor has the defects of large measurement errors and too thin wall thickness of the structure at the measurement point. In addition, the dragging tension of underwater array cables in water is generally below 300kg. The use of this type of sensor can no longer meet the tension measurement needs of this type of cable. Therefore, it is necessary to develop a tension sensor for underwater small load tension measurement. Utility Model Content

The floating bracket is rotatably connected to the mounting seat through a pin shaft, and the two ends of the sensor assembly are respectively hinged to the floating bracket and the mounting seat. A number of guide wheels are arranged on the floating bracket, and the guide wheels are distributed in a circular arc. The tow cable is supported on the guide wheels.

[0005] Furthermore, a blocking column is provided on the floating support, and the blocking column is located above the guide wheel.

[0006] Furthermore, the gap between the blocking column and the guide wheel is less than 9 mm.

[0007] Furthermore, a material guiding cover is provided on the floating support, and the material guiding cover is trumpet-shaped.

[0008] Furthermore, the material guiding cover is arranged at the feeding end of the floating support.

[0009] Furthermore, the sensor assembly includes a shell, a connecting rod, a hinge seat, a tension and compression sensor and a connector. The tension and compression sensor is sealed and arranged in the shell. The connector is electrically connected to the tension and compression sensor. The connecting rod is seal-slidably arranged on the shell, and one end of the connecting rod acts on the tension and compression sensor, and the other end is hinged to the floating bracket. The hinge seat is fixed on the shell, and the hinge seat is hinged to the mounting seat.

[0021] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0022] An underwater winch tension measuring device, such as Figures 1-4As shown, the system comprises a mounting base 1, a floating bracket 2, and a sensor assembly 3. The floating bracket 2 is rotatably connected to the mounting base 1 via a pin 4. The sensor assembly 3 is hinged at both ends to the floating bracket 2 and the mounting base 1, respectively. The floating bracket 2 is provided with a plurality of guide wheels 21 arranged in a circular pattern, and the towline is supported on these guide wheels 21. During measurement, the towline acts on the floating bracket 2, which in turn applies a force to the sensor assembly 3, which is then used to measure the force.

[0023] In one embodiment, if Figures 1-4 As shown, a stopper 22 is also provided on the floating support 2, and the stopper 22 is located above the guide wheel 21. A passage is formed between the stopper 22 and the guide wheel 21 to allow the towline to pass through. The stopper 22 limits the risk of the towline being derailed during the cable arrangement process.

[0024] In the above embodiment, if Figures 1-4 As shown, the gap between the blocking column 22 and the guide wheel 21 is less than 9 mm. The guide wheel 21 surface is provided with a U-shaped groove.

[0025] In one embodiment, if Figures 1-4 As shown, a material guide cover 23 is provided on the floating support 2, and the material guide cover 23 is trumpet-shaped.

[0026] In one embodiment, if Figures 1-4 As shown, the material guide cover 23 is arranged at the feeding end of the floating support 2. The towline is guided into the floating support 2 by the material guide cover 23 and supported on the guide wheel 21.

[0027] In one embodiment, if Figures 1-4 As shown, the sensor assembly 3 includes a housing 31, a connecting rod 32, an articulated seat 33, a tension and compression sensor 34, and a connector 35. The tension and compression sensor 34 is sealed within the housing 31, and the connector 35 is electrically connected to the tension and compression sensor 34. The connecting rod 32 is sealed and slidably mounted on the housing 31. One end of the connecting rod 32 acts on the tension and compression sensor 34, and the other end is hinged to the floating support 2. The articulated seat 33 is fixed to the housing 31 and articulated to the mounting seat 1. The tow cable acts on the floating support 2, and the floating support 3 acts on the tension and compression sensor 34 through the connecting rod 32, and data is collected through the tension and compression sensor 34.

[0028] In the above embodiment, if Figures 1-4 As shown, an oil filling port and an exhaust port are provided on the housing 31. This facilitates the oil filling compensation and exhaust of the sensor, meeting the requirements of 6000 meters underwater.

[0029] This new tension measuring device is mounted on the guide device of the winch cable arrangement mechanism and accurately measures the tension of the underwater array cable indirectly. It uses an oil-filled compensation structure to meet deepwater pressure resistance requirements.

[0030] The tension measuring device adopts the working principle of the tension and pressure sensor. By packaging the tension and pressure sensor and designing the structure, the sensor can accurately measure the tiny tension changes of the array cable.

[0031] The above are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. Without departing from the spirit and scope of the present invention, modifications or equivalent replacements of the present invention should be included in the scope of protection of the claims of the present invention.
