[0002] In recent years, the development and utilization of underwater resources and underwater blasting and demolition using explosives have been increasing, and research on the underwater explosion energy of explosives is very necessary.

[0003] The underwater explosion energy test device of explosives can simulate the conditions of underwater blasting construction site, and provide conditions for studying the underwater explosion energy of explosives. Due to the incompressible characteristics of water medium, after the underwater explosion of explosives, part of the energy will propagate outward through the water medium in the form of waves, causing vibration of the adjacent stratum medium. When the vibration intensity reaches a certain value, it will cause damage to the ground and underground buildings; although the test amount of some underwater explosion energy tests is small, such as 10g of single-element explosive test amount and 20g of industrial explosive test amount, the explosion vibration effect caused is quite strong, and the number of tests is large, which will cause frequent vibration of surrounding buildings, especially when it is close to the explosion energy test device and the underground structure is complex, it will cause fatigue damage to surrounding buildings and adjacent strata, causing permanent damage. Therefore, a device for underwater explosion test is proposed. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this technical field without creative work are within the scope of protection of the utility model.

[0023] See also Figures 1-5 The device for underwater explosion test of this embodiment includes an explosion-proof steel barrel 1, and also includes a support groove seat 2 cast on the ground, a plurality of rubber wheels 3 are placed in the support groove seat 2, the explosion-proof steel barrel 1 is placed on the rubber wheel 3, a plurality of fixing sleeves 4 are fixedly installed on the outer wall of the peripheral side of the explosion-proof steel barrel 1, a fixing rope 5 is passed through the fixing sleeve 4, both ends of the fixing rope 5 are fixedly connected with a first fixing plate 6, a plurality of first ground nails 7 inserted into the ground are passed through the upper surface of the first fixing plate 6, and an installation unit 8 for installing explosives is installed on the explosion-proof steel barrel 1.

[0024] like Figures 1-3As shown, the structure of the underwater explosion test device in the utility model is similar to the existing structure of the underwater explosion test device. The main improvement of the utility model is that when the underwater explosion test is needed, the utility model casts a support groove seat 2 on the ground, places a plurality of rubber wheels 3 in the support groove seat 2, hoists the explosion-proof steel drum 1 onto the rubber wheel 3, tightens the two ends of the fixing rope 5, places the first fixing plate 6 at the end of the fixing rope 5 on the ground, tightens the explosion-proof steel drum 1 through the fixing sleeve 4 on the outer wall of the explosion-proof steel drum 1, and uses the first ground nail 7 to fix the first fixing plate 6 on the outer wall of the explosion-proof steel drum 1. The fixed plate 6 is fixed on the ground. At this time, water can be released into the explosion-proof steel barrel 1. The staff uses a ladder to lift the explosives and put them into the explosion-proof steel barrel 1. At this time, the explosives in the explosion-proof steel barrel 1 can be detonated for testing. The explosion-proof steel barrel 1 is supported and buffered by the rubber wheel 3. Multiple fixed ropes 5 cooperate with the fixed sleeve 4 to tighten the explosion-proof steel barrel 1, so that the vibration generated by the explosion is released through the rubber wheel 3, reducing the damage caused by the underwater explosion to the surrounding buildings and adjacent strata. The rubber wheel 3 can be made of waste car tires to reduce the manufacturing cost. The overall structure is simple, the manufacturing is convenient, and it is easy to test.

[0025] like Figure 2 , 3 As shown, multiple rubber wheels 3 in the support groove seat 2 are stacked in multiple layers, and connecting ropes 9 are inserted between each layer of rubber wheels 3. Two adjacent layers of rubber wheels 3 are stacked in a staggered distribution; the rubber wheels 3 stacked in multiple layers and staggered in adjacent layers can improve the buffering effect of the explosion-proof steel drum 1, and the multiple rubber wheels 3 in each layer are connected by connecting ropes 9 to achieve the connection of the multiple rubber wheels 3, thereby facilitating the placement of the rubber wheels 3, and at the same time limiting the multiple rubber wheels 3 in a single layer.

[0026] like Figures 2-4 As shown, a plurality of inserting tubes 10 are fixedly connected to the bottom surface of the explosion-proof steel barrel 1, and the plurality of inserting tubes 10 are respectively inserted into a plurality of rubber wheels 3 on the top layer; the inserting tubes 10 on the bottom surface of the explosion-proof steel barrel 1 are inserted into the rubber wheels 3 on the top layer, and the rubber wheels 3 restrict the explosion-proof steel barrel 1 through the inserting tubes 10, so that the explosion-proof steel barrel 1 remains stable when the explosives explode.

[0027] like Figure 1 , 2 As shown, the outer wall of the support groove seat 2 is an inclined staircase-like structure, and the support groove seat 2 is truncated cone-like; the support groove seat 2 can stably support and restrict the rubber wheel 3 inside it to maintain strength.

[0028] like Figure 1 , 3, as shown in FIGS. 5, the installation unit 8 includes two groups of support rods 82 symmetrically installed on the outer wall of the explosion-proof steel barrel 1 and an explosive installation rod 81 slidably connected inside the explosion-proof steel barrel 1. Two guide wheels 83 are rotatably connected between each group of support rods 82. Both ends of the upper surface of the explosive installation rod 81 are fixedly connected with pull ropes 84, and the pull ropes 84 are slidably connected between the two guide wheels 83. When placing the explosive inside the explosion-proof steel barrel 1, pull the two pull ropes 84. The pull ropes 84 slide with the guide wheels 83, and the support rods 82 support the guide wheels 83. The two pull ropes 84 pull the explosive installation rod 81 to the upper opening of the explosion-proof steel barrel 1. At this time, the explosive can be installed on the explosive installation rod 81, and then loosen the pull ropes 84. The explosive installation rod 81 will bring the explosive to the lower end inside the explosion-proof steel barrel 1 due to its gravity. At this time, the explosive can be activated to conduct an underwater explosion test on the explosive, which is convenient for installing the explosive inside the explosion-proof steel barrel 1.

[0029] As Figure 3 , 5 shown, the installation unit 8 further includes two second fixing plates 85 installed on the ground. A limiting ring 86 is fixedly connected to the upper surface of the second fixing plate 85. A plurality of second ground nails 87 inserted into the ground are passed through the second fixing plate 85. The other ends of the two pull ropes 84 respectively pass through the two limiting rings 86. When pulling the pull ropes 84 to raise the explosive installation rod 81, the pull ropes 84 slide with the limiting rings 86. The second fixing plate 85 at the bottom surface of the limiting ring 86 is fixed to the ground by the second ground nails 87, thereby restricting the limiting ring 86. After the explosive is installed on the explosive installation rod 81, loosen the pull ropes 84 to control the downward movement of the explosive. According to the test requirements, the pull ropes 84 can be tied to the limiting rings 86, thereby restricting the pull ropes 84, controlling the height of the explosive installation rod 81 by the pull ropes 84, and further controlling the depth of the explosive inside the explosion-proof steel barrel 1 to adapt to different test requirements and improve adaptability.

[0030] As Figure 1 , 3 , 5 shown, the first ground nail 7 and the second ground nail 87 are respectively obliquely inserted through the first fixing plate 6 and the second fixing plate 85 and inserted into the ground; the first ground nail 7 and the second ground nail 87 obliquely inserted into the ground can improve the fixing strength of the first fixing plate 6 and the second fixing plate 85.

[0031] Implementation steps in this embodiment: When an underwater explosion test is required, a support trough base 2 is poured on the ground. A plurality of rubber wheels 3 are connected by a connecting rope 9 and stacked in the support trough base 2. The adjacent two layers of rubber wheels 3 are stacked in a staggered distribution. The explosion-proof steel barrel 1 is hoisted onto the rubber wheels 3. The insertion tube 10 at the bottom of the explosion-proof steel barrel 1 is inserted into the topmost layer of rubber wheels 3. The rubber wheels 3 limit the explosion-proof steel barrel 1 through the insertion tube 10. The two ends of the fixing rope 5 are tightened so that the first fixing plate 6 at the end of the fixing rope 5 is placed on the ground. A plurality of fixing ropes 5 tighten the explosion-proof steel barrel 1 through the fixing sleeve 4 on the outer wall of the explosion-proof steel barrel 1. The first fixing plate 6 is fixed to the ground by using the first ground nail 7. At this time, water can be filled into the explosion-proof steel barrel 1. When the staff uses a ladder to raise and pulls the pull rope 84 to make the explosive installation rod 81 rise, the pull rope 84 slides with the limit ring 86 and the guide wheel 83. The second fixing plate 85 on the bottom surface of the limit ring 86 is fixed to the ground by the second ground nail 87, thereby restricting the limit ring 86. The explosive is installed on the explosive installation rod 81, and then the pull rope 84 is loosened to control the downward movement of the explosive. According to the test requirements, the pull rope 84 can be tied to the limit ring 86, thereby restricting the pull rope 84 and controlling the height of the explosive installation rod 81 by the pull rope 84. The explosive is put into the explosion-proof steel barrel 1. At this time, the explosive in the explosion-proof steel barrel 1 can be detonated for testing. The explosion-proof steel barrel 1 is supported and buffered by the rubber wheels 3. A plurality of fixing ropes 5 cooperate with the fixing sleeve 4 to tighten the explosion-proof steel barrel 1, so that the vibration generated by the explosion is dissipated through the rubber wheels 3, reducing the damage caused by the underwater explosion to the surrounding buildings and adjacent strata.
