TECHNICAL FIELD
[0001] The present application relates to the field of marine engineering and blasting monitoring, and particularly relates to a sleeve type multi-explosive source precise positioning device for offshore explosion test. BACKGROUND
[0002] With the increasing attention to the exploration and development of marine resources, offshore platforms play an irreplaceable role in resource development, environmental monitoring and scientific research. Whether it is platform construction, performance testing, or later demolition, blasting technology has become an indispensable means. However, the accuracy and safety of blasting operation are directly related to the test effect and platform stability, so the high-precision positioning of explosive sources in offshore platform tests is particularly important. Precise explosive source positioning not only improves the reliability of test data, but also effectively reduces safety risks, providing a solid guarantee for the smooth implementation of marine engineering.
[0003] Currently, the positioning method for explosive sources used in offshore platform or ship tests generally adopts a mechanical positioning method, that is, a positioning method in which the explosive source is fixed at a predetermined position by a rigid or semi-rigid structure (such as an elongated rod, a bracket, etc.). This method is simple in structure, low in cost and intuitive in operation, but it has many problems in actual operation. Because the elongated rod is long, it will produce deflection under the action of its own gravity, water flow, wave and other external loads, resulting in deviation between the actual position of the explosive source and the expected position, and reducing the positioning accuracy. In addition, the instantaneous force of the explosion impact load is extremely large, and the elongated rod is easy to break or damage, especially in high-energy blasting tests, the positioning device needs to be replaced or repaired after each test, increasing the test cost. The operation environment at sea is complex, and harsh conditions such as wind and wave, salt fog, etc. put higher requirements on the installation and maintenance of equipment. The installation and disassembly process of the elongated rod is complicated, and requires professional personnel and equipment support, increasing the complexity and difficulty of the operation.
[0004] Because there is little research on the positioning device for explosive sources in offshore tests, there is currently only a single explosive source positioning device for offshore tests, but in actual test process, sometimes two or more explosive sources need to be placed. Therefore, it is urgent to design a reasonable structure device to effectively enhance the convenience and economy of the test and provide a more practical and convenient device for offshore tests.

The vertical sliding rail sleeve shaft base 1.1 has two thin rods protruding from one side of the bottom, which penetrate through the two circular holes on one side of the device base 1.3, so that the vertical sliding rail sleeve shaft base 1.1 can rotate around the device base 1.3. The adjustable angle support rod 1.2 is connected to the vertical sliding rail sleeve shaft base 1.1 and the device base 1.3 by bolts. By adjusting the tightness of the bolt in the middle of the adjustable angle support rod 1.2, the device base 1.3 can be adjusted and fixed to the appropriate angle. The entire device can be clamped on the rail or platform side according to the need by adjusting the tightness of the base fastening component 1.4 and the protruding part below the device base 1.3.
[0045] As shown in Figure 3 , the part 2.1 is a vertical sliding rail track sleeve, the part 2.2 is a positioning slider, and the part 2.3 is a lower end slider. The vertical sliding rail track sleeve 2.1 is sleeved on the vertical sliding rail sleeve shaft base 1.1, so that the vertical sliding rail track sleeve 2.1 can rotate around the vertical sliding rail sleeve shaft base 1.1 as an axis. The vertical sliding rail track sleeve 2.1 is provided with 12 protruding bolts at the bottom, which penetrate through the 12 corresponding limiting holes above the vertical sliding rail sleeve shaft base 1.1, to realize the effect of fixed rotation angle.

By tightening the slider locking bolt above the positioning slider 2.2, the positioning slider 2.2 is fixed at the current position, and the positions of the two sliders 2.2 and 2.3 are fixed.
[0046] As Figure 4 shown, the part 3.1 is a horizontal sliding rail track, the part 3.2 is an end pin, and the part 3.3 is a horizontal sliding rail slider. The end pin 3.2 penetrates the lower end slider 2.3 and the horizontal sliding rail track 3.1, so that the horizontal sliding rail track 3.1 is fixed on the lower end slider 2.3, and the horizontal sliding rail slider 3.3 can slide left and right on the horizontal sliding rail track 3.1.
[0047] As Figure 5 , Figure 6 , Figure 7 shown, the part 4.1 is a telescopic rod base, the part 4.2 is a telescopic rod fixed end, the part 4.3 is a sleeve, and the part 4.8 is an extension tube. The telescopic rod limiting and fixing device can preferably be a telescopic rod fixing lock, wherein the part 4.4 is a telescopic rod telescopic fixing lock cylinder, the part 4.5 is a telescopic rod telescopic fixing lock handle, the part 4.6 is a telescopic rod telescopic fixing lock body, and the part 4.7 is a telescopic rod telescopic fixing lock center shaft. The cylindrical sleeve at the end of the telescopic rod base 4.1 can be sleeved on the cylinder on the horizontal sliding rail slider 3.3, and there are multiple positioning screw holes on the side of the cylindrical sleeve of the telescopic rod base 4.1. After aligning with the positioning holes on the side of the cylinder on the horizontal sliding rail slider 3.3, the telescopic rod base 4.1 can be fixed with bolts, so that the telescopic rod base 4.1 is fixed on the horizontal sliding rail slider 3.3. The two left and right extension bolts at the tail end of the telescopic rod fixed end 4.2 pass through the bolt holes above the telescopic rod base 4.1, so as to fix the telescopic rod fixed end 4.2 on the telescopic rod base 4.1 and fix the angle. The sleeve 4.3 is clamped in the telescopic rod fixed end 4.2 by shape. The extension tube 4.8 is sleeved in the sleeve 4.3 and can be extended and retracted.

The telescopic rod telescopic fixing lock handle 4.5 can rotate around the center shaft. Note that the hole in the middle of the cylinder of the telescopic rod telescopic fixing lock handle 4.5 is not at the center, but is an eccentric circle. Therefore, when the control handle of the telescopic rod telescopic fixing lock handle 4.5 is pulled upwards, the lower side of the thicker cylinder will press downwards, pushing the telescopic rod telescopic fixing lock cylinder 4.4 downwards and clamping the telescopic extension of the extension tube 4.8, so as to control the length of the extension of the extension tube 4.8.

The adjustable angle support rod 1.2 is adjusted to the appropriate angle, the vertical slide rail track sleeve 2.1 is sleeved on the vertical slide rail sleeve shaft base 1.1, and the rotating bolt is adjusted to the required angle. Then, the lower end sliding block 2.3 and the positioning sliding block 2.2 are slid along the track sleeve to the predetermined height, and the sliding block 2.2 fixing bolt is tightened to fix the position. Next, the horizontal slide rail track 3.1 is fixed on the lower end sliding block through the end bolt 3.2, so that the horizontal slide rail sliding block 3.3 can slide left and right on the track. Then, the telescopic rod base 4.1 is sleeved on the cylinder of the horizontal slide rail sliding block 3.3 and is fixed by a bolt. After adjusting the angle of the telescopic rod fixed end 4.2, it is locked by a bolt. The sleeve 4.3 is clamped into the telescopic rod fixed end 4.2, and the length of the telescopic rod fixed end 4.2 is adjusted and locked by rotating the telescopic rod telescopic fixing lock handle 4.5 to control the eccentric circle mechanism to press down the telescopic rod telescopic fixing lock core 4.4. Finally, the float support piece 5.5 is inserted into the end slide rail base 5.3 and fixed at the extended height by the end positioning piece 5.2. The float support piece 5.5 and the float 5.6 are connected by a steel wire rope, and the explosive is hung at the rope hole at the lower end of the float 5.6.
