Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment technology for underwater construction, and specifically to a diamond wire cutting saw. Background Technology

[0002] With the development of marine technology, deep-sea pipelines are playing an increasingly important role in marine engineering, and are widely used in fields such as water and fluid transport. During use, various factors can lead to pipeline damage. For example, due to long-term exposure to seawater and other corrosive environments, deep-sea pipelines may experience corrosion and wear, affecting their structural integrity and function. Simultaneously, submarine earthquakes, landslides, anchoring accidents, or other underwater activities can cause external impacts, resulting in damage or rupture. Furthermore, long-term exposure to pressure and temperature changes, as well as dynamic loads such as ocean currents, can lead to material fatigue, resulting in cracks or fractures.

[0003] During the cutting of subsea pipelines, diamond wire saws are required to cut the pipelines. However, once the diamond wire saw is sent underwater, it lacks its own power positioning device and can only be guided and pulled into place by divers, resulting in high personnel costs and operational risks.

[0008] A propulsion assembly, comprising a plurality of propellers, each propeller being mounted on the lower support plate;

[0009] The electronic housing, containing a sensor array, is mounted on the lower support plate.

[0031] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0032] In one specific implementation, such as Figures 1-6 As shown, the diamond wire saw provided by this utility model includes a saw body 100 and a power positioning device 200 for providing power propulsion for the saw body 100. The power positioning device 200 also includes a support frame, a propulsion assembly, and a sensor group. The support frame includes an upper support plate 1 and a lower support plate 2. The saw body 100 is detachably mounted on the upper support plate 1. The propulsion assembly includes multiple propellers, each of which is mounted on the lower support plate 2. The sensor group is used to collect the current coordinates of the target point of the saw body 100 and underwater image information of the current area.

[0033] Specifically, the sensor assembly may include a tilt sensor, which is used to obtain the underwater attitude of the device. The obtained attitude angle indicates the stability of the current device operation and whether there are attitude problems such as capsizing or top-heavyness, allowing for early intervention in case of problems. The sensor assembly also includes an underwater USBL (Ultra-Short Base) positioning transmitter, which includes a transmitting transducer, a transponder, and a receiving array. The transmitting transducer and receiving array are mounted on a ship, while the transponder is fixed to the underwater hull. The transmitting transducer emits an acoustic pulse, which the transponder receives and then transmits back. The receiving array receives this pulse, measures the phase difference in the X and Y directions, and calculates the distance R from the underwater device to the array based on the arrival time of the sound wave. This allows for the calculation of the underwater detector's position on a planar coordinate system and its depth.

[0034] In this way, after the diamond wire cutting saw is sent underwater, it can use its own propulsion component to reach the designated position without relying on divers to pull and guide it into place, thus reducing personnel costs and operational risks.

[0035] To improve the reliability of propeller installation, the propulsion assembly also includes a mounting structure through which the propeller is detachably mounted to the lower support plate 2.

[0036] Specifically, the mounting structure includes a mounting plate 41 and a clamp 42. The mounting plate 41 is detachably mounted on the lower support plate 2, and the clamp 42 is fixed to the mounting plate 41. The outer shell of the propeller is detachably clamped into the clamp 42.

[0037] The aforementioned propellers consist of four components: two propellers form the first propulsion assembly, and the other two form the second propulsion assembly. The propulsion directions of the two propellers in the first propulsion assembly are at an angle of 30-75°, and / or, the propulsion directions of the two propellers in the second propulsion assembly are at an angle of 30-75°. A total of four propellers are arranged at a certain angle to the central axis of the equipment to provide force components in both the X and Y axes when the propellers rotate. The direction of movement—forward, backward, left-front turn, right-front turn, left-rear turn, right-rear turn, and turning in place—is determined by specifying the positive and negative directions of these force components (propeller forward and reverse rotation) and their magnitude (rotation speed).

[0038] Furthermore, the diamond wire saw also includes an electronic housing 5, in which the sensor assembly is installed. The electronic housing 5 is mounted on the lower support plate 2 to improve the safety of the sensor assembly underwater. The electronic housing 5 is typically a waterproof structure.

[0039] To improve support reliability, the support frame also includes a lateral support plate 6. The bottom end of the lateral support plate 6 is installed on the lower support plate 2, and the top end of the lateral support plate 6 is installed on the upper support plate 1. The electronic compartment 5 is not positioned between the upper support plate 1 and the lower support plate 2.

[0040] There are two lateral support plates 6, which are arranged laterally at intervals. In this way, the installation space of the electronic compartment 5 is formed between the two lateral support plates 6, the upper support plate 1 and the lower support plate 2, thereby improving the overall structural compactness of the device.

[0041] The above specific embodiments further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above are only specific embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made on the basis of the technical solution of this utility model should be included within the scope of protection of this utility model.
