Description

Technical Field

[0001] The utility model relates to the field of cable tension monitoring equipment, in particular to an inflation fixing device for a mooring cable tension monitoring sensor. Background Art

[0002] Mooring ropes are a key component of a ship's mooring system, and their tension directly impacts the stability and safety of the ship's mooring. Mooring rope tension is constantly changing due to factors such as current velocity, tides, swells, wind speed, and operational conditions. In severe weather conditions, such as typhoons and high waves, rope tension can increase dramatically, potentially leading to uneven force distribution, breakage, and even serious safety incidents such as loss of control of the vessel. Therefore, real-time monitoring of mooring rope tension is crucial.

[0003] The mooring cable tension monitoring system is usually composed of sensors and excitation units at the front end, and server computing programs and interactive display platforms at the back end. The sensor is a vibration signal acquisition device that is fixedly installed on the cable through a fixed structure and is the core hardware of the system. Figure 1 As shown, the existing sensor fixing structure includes a mounting plate 2, with the sensor body 1 fixedly mounted on the upper end surface of the mounting plate 2. The lower end surface of the mounting plate 2 is provided with a positioning block 3 for positioning the cable. The mounting plate 2 also includes a fixing plate 4. The mounting plate 2 and the fixing plate 4 are respectively secured with bolts 5 and nuts 6 at their ends, thereby pressing the cable between the fixing plate 4 and the positioning plate 3. This fixing structure has the following shortcomings when in use: First, the process of manually tightening the nuts is cumbersome and time-consuming, and requires alternating tightening on both sides, which is not only time-consuming and labor-intensive, but may also lead to an unstable installation due to improper operation. Second, due to the lack of an effective pre-tightening mechanism, when the cable is subjected to high tension, its wire diameter may decrease due to the force, thereby affecting the stability and accuracy of the sensor. Summary of the Invention

[0004] In view of the above problems existing in the prior art, the utility model provides an inflation fixing device for a mooring rope tension monitoring sensor which has a simple structure, is easy to install, has good stability and strong adaptability.

[0005] The technical solution adopted by the present invention is as follows: An inflation and fixing device for a mooring rope tension monitoring sensor includes a sensor body, which is fixedly mounted on a mounting plate, and an L-shaped fixing bracket is fixedly connected to the lower part of the mounting plate, and the L-shaped fixing bracket includes a vertical plate and a horizontal plate, and the vertical plate is fixedly connected to the mounting plate, and the horizontal plate is parallel to the mounting plate, and an inflatable airbag is provided on the lower end surface of the mounting plate corresponding to the horizontal plate of the L-shaped fixing bracket, and an air pump is provided in the housing of the sensor body, and the air inlet end of the air pump is connected to the air inlet hole provided on the housing of the sensor body through a pipe, and the air outlet end is connected to the inflatable airbag through a pipe, and is used to provide gas to the inflatable airbag, and the cable is clamped between the inflatable airbag and the horizontal plate of the L-shaped fixing bracket after the inflatable airbag is inflated.

[0006] Furthermore, an arc-shaped groove matching the cable is provided on the transverse plate of the L-shaped fixing bracket.

[0007] Furthermore, a reinforcing rib is provided between the vertical plate and the mounting plate of the L-shaped fixing bracket.

[0008] Furthermore, an anti-falling ring is provided on the mounting plate, and an anti-falling rope for connecting to the cable is connected to the anti-falling ring.

[0009] Furthermore, it also includes a pressure sensor and an air pump control module. The pressure sensor is installed inside the inflatable airbag or connected to it, and is used to monitor the pressure inside the inflatable airbag in real time and send the monitoring data to the air pump control module. The air pump control module is set in the shell of the sensor body, receives the signal from the pressure sensor, and controls the start and stop of the air pump according to a preset pressure range.

[0010] Furthermore, the inflatable airbag is provided with an electromagnetic deflation valve, which is opened or closed under the control of the inflation pump control module to release the gas in the inflatable airbag.

[0011] The beneficial effects of the present invention are as follows: the present invention avoids the process of manually tightening the nut in the traditional way by setting an inflatable airbag, thereby greatly simplifying the installation steps, reducing the installation difficulty, reducing the installation time, and making the installation process more convenient; the inflatable airbag can tightly clamp the cable after inflation, provide stable supporting force, ensure the firm installation of the sensor on the cable, and can better adapt to cables of different diameters and materials, improving the adaptability and stability of the installation; the air pump control module can automatically control the start and stop of the air pump and the opening and closing of the electromagnetic air release valve according to a preset pressure range, which can ensure that the pressure in the inflatable airbag is always kept within a safe range, avoiding safety hazards caused by excessive or low pressure, and the inflatable airbag can always fit tightly to the cable. Even if the cable changes due to the force-bearing wire diameter, the stable clamping force can be maintained by adjusting the gas pressure in the inflatable airbag.

[0015] In order to facilitate the understanding of the present invention, the present invention will be described in more comprehensive and detailed manner below in conjunction with the accompanying drawings and preferred embodiments of the specification, but the protection scope of the present invention is not limited to the following specific embodiments.

[0016] like Figure 2-Figure 3 As shown, this embodiment provides an inflation and fixing device for a mooring line tension monitoring sensor. The device includes a sensor body 1, which is responsible for monitoring changes in line tension. The structure and operating principle of the sensor body 1 are well known to those skilled in the art. The sensor body 1 is fixedly mounted on a mounting plate 2. An L-shaped fixing bracket 7 is fixedly connected to the lower portion of the mounting plate 2. The L-shaped fixing bracket 7 includes a vertical plate 701 and a horizontal plate 702. The vertical plate 701 is fixedly connected to the mounting plate 2, and the horizontal plate 702 is parallel to the mounting plate 2. An inflatable airbag 8 is disposed on the lower end surface of the mounting plate 2, corresponding to the horizontal plate 702 of the L-shaped fixing bracket 7. An air pump 12 is disposed within the housing of the sensor body 1. The air inlet of the air pump 12 is connected to an air inlet 13 provided in the housing of the sensor body 1 via a pipe, and the air outlet of the air pump 12 is connected to the inflatable airbag 8 via a pipe, thereby supplying air to the airbag 8. After inflation, the airbag 8 clamps the line 11 between the airbag 8 and the horizontal plate 702 of the L-shaped fixing bracket 7.

[0017] By adopting the above technical solution, in the initial state, the inflatable airbag 8 is in an uninflated state, and the cable 11 can be freely inserted into the L-shaped fixing bracket 7. When fixing, the air pump 12 is started by the control switch to inflate the inflatable airbag 8. The inflatable airbag 8 gradually expands and fits on the cable 11 until the cable 11 is firmly clamped between the inflatable airbag 8 and the cross plate 702, and then the air pump 12 is turned off to stop inflation.

[0018] To improve the stability of cable clamping, in this embodiment, an arcuate groove 703 matching the cable is provided on the horizontal plate 702 of the L-shaped fixing bracket 7, and the cable 11 is embedded in the arcuate groove 703. The setting of the arcuate groove 703 can adapt to cables of different diameters.

[0019] In order to improve the connection strength between the L-shaped fixing bracket 7 and the mounting plate 2, in this embodiment, a reinforcing rib 9 is provided between the vertical plate 701 and the mounting plate 2 to enhance the stability and strength of the structure.

[0020] To provide additional safety and prevent the sensor from accidentally falling, in this embodiment, an anti-falling ring 10 is provided on the mounting plate 2 , and an anti-falling rope for connecting to the cable 11 is connected to the anti-falling ring 10 .

[0021] As another embodiment, it also includes a pressure sensor and an air pump control module. The pressure sensor is installed inside the inflatable airbag 8 or connected thereto, and is used to monitor the pressure inside the inflatable airbag 8 in real time and send the monitoring data to the air pump control module. The air pump control module is arranged in the housing of the sensor body 1, receives the signal from the pressure sensor, and controls the start and stop of the air pump 12 according to a preset pressure range. The pressure sensor monitors the pressure inside the inflatable airbag 8 in real time. The air pump control module receives the pressure sensor signal. When the pressure reaches a preset value during the inflation of the inflatable airbag 8, the air pump control module controls the air pump 12 to automatically stop. During the operation of the tension monitoring sensor, if the cable diameter decreases or other conditions occur, and the pressure sensor detects that the pressure inside the inflatable airbag 8 is lower than the set threshold, the air pump control module automatically starts the air pump 12 to inflate, and automatically shuts down the air pump 12 after reaching the set value.

[0022] In order to avoid excessive internal pressure in the inflatable airbag 8 in certain circumstances, an electromagnetic deflation valve can also be provided on the inflatable airbag 8. Under the control of the inflation pump control module, the electromagnetic deflation valve opens or closes to release the gas in the inflatable airbag 8, thereby ensuring that the pressure in the inflatable airbag is always maintained within a safe range, avoiding safety hazards caused by excessively high or low pressure.

Therefore, it is to be understood that the present invention is not limited to the specific embodiments disclosed, and modifications and other embodiments are intended to be included within the scope of the appended claims. Although specific terms are employed herein, they are used in a generic and descriptive sense only and not for purposes of limitation.
