Description

Technical Field

[0001] This invention relates to the field of ammunition disposal technology, specifically to an underwater crushing container for low-yield obsolete ammunition. Background Technology

[0002] Due to the early production of low-yield obsolete ammunition, their packaging methods vary greatly. Furthermore, because of the long storage period (the original lifespan was only 15 years, but a large number of stockpiled ammunition awaiting destruction had been stored for more than 30 years), the plastic lanyards, canvas bags, and other accessories of the ammunition are severely aged and need to be destroyed. However, due to the wide variety and large quantity of traditional or modern low-yield ammunition, and the fact that some ammunition have very complex structures, the process of disassembling and destroying them is very difficult, and the only option is to "detonate them."

[0003] Currently, the disposal of low-yield obsolete munitions often employs techniques such as high-pressure abrasive water cutting and equipment dismantling. These methods suffer from high costs and low efficiency, particularly for small munitions like grenades and tear gas canisters, which are primarily made of engineering plastics. These munitions are numerous and require high disposal efficiency; traditional dismantling and burning methods are inefficient and difficult to implement. Furthermore, the unstable technical condition of traditional methods makes fully automated operation difficult, requiring remote monitoring and mobile personnel intervention to maintain continuous operation, posing safety risks to the disposal process. Additionally, the frequent need for human intervention impacts overall operational efficiency and cycle time. Therefore, we propose an underwater fragmentation container for low-yield obsolete munitions. Summary of the Invention

[0076] In the description of this patent, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this patent according to the specific circumstances.

[0077] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "more" means two or more, unless otherwise explicitly specified.

[0078] A type of low-yield obsolete munition underwater fragmentation container, such as Figure 1-2As shown, it includes: a belt conveyor 1, an underwater crushing mechanism 2, a main water tank 3, the underwater crushing mechanism 2 placed inside the main water tank 3, a downstream water control cone 4, and a pot-shaped explosion-proof chamber 5, a U-shaped explosion-proof waterway 7, a water transfer tank 8, a dense net retrieval device 11, and a connecting device 12; the belt conveyor 1 is used to transport the low-yield scrapped ammunition to be crushed to the inlet 55 of the underwater crushing mechanism 2; the upper part of the explosion-proof shield of the underwater crushing mechanism 2 is exposed outside the liquid level of the main water tank 3, and the lower part of the blade chamber 57 is immersed below the liquid level, used to dismantle the low-yield scrapped ammunition underwater; the first collection port 83 of the downstream water control cone 4 is connected to the discharge end of the blade chamber 57, used to guide the dismantled material to the second collection port 87 of the pot-shaped explosion-proof chamber 5; the guide port 8 of the pot-shaped explosion-proof chamber 5... The 5 is connected to the guide outlet 96 on the side wall of the main water tank 3, and is used to trigger the detonation of materials with a probability of detonation in the pot-shaped explosion-proof chamber 5; the U-shaped explosion-proof waterway 7 is placed outside the main water tank 3, and the inlet 104 of the U-shaped explosion-proof waterway 7 is connected to the guide outlet 96, and is used to further trigger the detonation of materials with a probability of detonation in the U-shaped explosion-proof waterway 7; the transfer tank 8 is placed below the U-shaped explosion-proof waterway 7, and is used to receive the materials falling from the outlet 105 of the U-shaped explosion-proof waterway 7; the lower end of the dense net retrieval device 11 is placed in the transfer tank 8, and is used to retrieve and transfer the processed materials after filtering water; the upper end of the dense net retrieval device 11 is connected to the connecting device 12, and is used to transport the retrieved materials to the external incineration device for incineration.

[0079] like Figure 4 As shown, the belt conveyor 1 includes: a frame body 50; the lower end of the frame body 50 is provided with a front end connection position 43 for connecting to an external unpacking mechanism; the upper end of the frame body 50 is provided with a rear end connection position 44 for connecting to the feed inlet 55 of the underwater crushing mechanism 2; a transmission motor 48 is installed at the lower end of the frame body 50, and the transmission motor 48 is used to drive the vulcanizing line 49 on the frame body 50 to transport the small-yield scrap ammunition to be crushed from the lower end to the upper end.

[0080] The frame body 50 is provided with a lower support 45 at the bottom, a middle support 46 in the middle, and a rear support 47 at the top, which supports the frame body 50 into a transmission line that is lower at the bottom and higher at the top.

[0081] In this embodiment, the belt conveyor 1 is used to transport the small-yield scrapped munitions to be crushed from the external unpacking mechanism to the underwater crushing mechanism 2 for crushing. Since the underwater crushing mechanism 2 is generally placed in a water tank on a high platform, manual handling can be avoided by using the belt conveyor 1, thus improving transportation efficiency.

[0082] like Figure 5As shown, the explosion relief shield is provided from top to bottom as follows: upper protection zone 52, middle protection zone 53, feed inlet 55, and water permeable zone 56; the top surface of the upper protection zone 52 is provided with a reserved hole 54 for monitoring the inside of the shield; the bottom end of the water permeable zone 56 is connected to the blade cavity 57, and the blade cavity 57 is provided with a set of crushing blades.

[0083] In this embodiment, a first monitoring unit 13 can be installed above the reserved hole 54. Specifically, the first monitoring unit 13 can use a monitoring camera to monitor the material situation inside the explosion relief shield. Several holes are provided on the outer surface of the water-permeable area 56 so that the water in the main water tank 3 can be wetted after the material enters the feed port 55. Then the material falls into the blade chamber 57 and is broken and deconstructed. The upper protection area 52 and the middle protection area 53 of the explosion relief shield are raised structures to protect against the explosion caused by the deconstruction.

[0084] like Figure 6 and Figure 7 As shown, the crushing blade assembly includes: a transmission A-shaft 69 and a transmission B-shaft 70, which are laterally mounted on the blade cavity 57 via bearings 58; one end of the transmission A-shaft 69 extending out of the blade cavity 57 is connected to the output end of a waterproof reducer 62 via a coupling 61, and the waterproof reducer 62 is driven by an explosion-proof motor 63; multiple sets of blades 73 are provided on the transmission A-shaft 69, and multiple sets of blade spacer rings 72 are provided on the transmission B-shaft 70, with one side of the blade spacer ring 72 positioned between two adjacent blades 73; multiple sets of alternating large blade teeth 76 and small blade teeth 77 are provided on the edges of the blades 73, and multiple sets of annular key teeth 74 are provided on the edges of the blade spacer rings 72.

[0085] In this embodiment, two sets of bearing mounting positions 59 are respectively provided at both ends of the blade cavity 57 to facilitate the installation of bearings 58. The blade cavity 57 is a structure formed by the transmission side plates 65 at both ends and the fixed blade side plates 66 on both sides. The fixed blade side plates 66 are provided with multiple sets of mounting holes 67 for fixing to the bottom of the explosion-proof cover. Furthermore, the blade 73 is mounted on the transmission A shaft 69 through the blade inner mounting port 78, and the blade spacer 72 is mounted on the transmission B shaft 70 through the blade spacer inner mounting port 75. When the explosion-proof motor 63 rotates through the waterproof reducer 62, it pulls the blade 73 on the transmission A shaft 69 to rotate. When the material falls into the blade cavity 57, the blade 73 cuts the surface of the material. At the same time, since the edge of the blade spacer 72 is also provided with annular key teeth 74, the friction with the material surface can be increased, making it easier for the blade 73 to deconstruct the material surface.

[0086] like Figure 8As shown, the downstream water control cone 4 has an inverted frustum-shaped structure, and its top surface is an open first collection port 83, while its bottom surface is sealed by a perforated plate 81. The outer surface of the downstream water control cone 4 is an arc-shaped outer wall 80, and the inner wall is an arc-shaped inner wall 82. The downstream water control cone 4 is fixed to the discharge side of the blade cavity 57 by an outer liner connecting surface 79 provided on one side of the top end, and its mounting position is reinforced by an assembly fixing position 84 provided on the other side of the top end.

[0087] like Figure 9 As shown, the top of the pot-shaped explosion-proof chamber 5 is provided with the first material collection port 83, and the bottom is provided with the material guide port 85. The pot-shaped explosion-proof chamber 5 is also provided with an explosion relief port 86 and a stacking flushing port 88. The two sides of the pot-shaped explosion-proof chamber 5 are also provided with fixing positions 89 for fixing to the inner wall of the main water tank 3.

[0088] like Figure 10 As shown, the main water tank 3 is a box structure formed by plates 90. The top of the main water tank 3 is provided with an overflow port 91 for the working water level, the inner wall is provided with reinforcing ribs 92, and the interior is provided with a central water sealing plate 93. The bottom wall of the main water tank 3 is fixed with two sets of upper support frames 94 and two sets of lower support frames 95. The upper support frames 94 and lower support frames 95 cooperate with each other to support and install the pot-shaped explosion-proof compartment 5 inside the main water tank 3. The bottom surface of the main water tank 3 is also provided with load-bearing feet 97 for support.

[0089] like Figure 11 As shown, the water tank 8 includes a water storage tank 98 and at least one water storage tank 102. The water storage tank 98 is connected to one of the water storage tanks 102 via a water level control plate 100, and adjacent water storage tanks 102 are connected via a waterway 99. The U-shaped explosion-proof waterway 7 is located above the water storage tank 98, and one end of the dense net retrieval device 11 is placed inside the water storage tank 98. One of the water storage tanks 102 is also provided with a water tank inlet 101, and the water storage tank 102 is supported by a water tank support foot 103 at the bottom.

[0090] like Figure 12 As shown, the top surface of the U-shaped explosion-proof waterway 7 is provided with an explosion relief port 106, and multiple sets of water permeable holes 107 are provided on both sides. The explosion relief port 106 is composed of multiple through holes arranged on the top surface of the U-shaped explosion-proof waterway 7.

[0091] like Figure 13As shown, it also includes an elevated platform 6, which includes a main water tank elevated platform 108 and a transfer water tank elevated platform 109. The main water tank elevated platform 108 is provided with a main water tank elevated platform receiving surface 110 and a main water tank elevated platform support frame 111 for placing the main water tank 3. The transfer water tank elevated platform 109 is provided with a transfer water tank elevated platform receiving surface 112 and a transfer water tank elevated platform support frame 113 for placing the main water tank 8.

[0092] like Figure 14 As shown, the dense net retrieval device 11 includes: an upper drive chain shaft 114, a lower drive chain shaft 120, a retrieval motor 122, and a stainless steel dense net cable body 117. The retrieval motor 122 drives the stainless steel dense net cable body 117 between the upper drive chain shaft 114 and the lower drive chain shaft 120. The stainless steel dense net cable body 117 is equipped with a material discharge retrieval cover 118 and a retrieval catch plate 119. The upper part of the dense net retrieval device 11 also has a retrieval device and support frame connection position 115, and the lower part has a retrieval device support foot 121 for supporting the entire dense net retrieval device 11, resulting in a top-high, bottom-low configuration. Chain guards 116 are fitted onto the upper drive chain shaft 114 and the lower drive chain shaft 120.

[0093] like Figure 15 As shown, the connecting device 12 is supported by a fixed frame 13 and includes rollers 129 and bending pressure rollers 126. The rollers 129 are driven by a connecting device reduction motor 131 to drive the rubber line 127. Multiple sets of the bending pressure rollers 126 are provided to divide the connecting device 12 into an upper connecting platform, a climbing platform and a lower connecting platform. In addition, the connecting device 12 is provided with a top support frame 123, an internal support plate 124, a bottom locking frame 125, a height adjuster 128 and a lifting buckle 130, which form the entire support structure.

[0094] The second fixed frame 10 is equipped with a second monitoring unit 14, which can use a monitoring camera to monitor the transportation of materials on the dense net retrieval device 11.

[0095] like Figure 16 As shown, the high end of the dense net retrieval device 11 is supported by a first fixed frame 9. The top of the first fixed frame 9 is provided with a top connecting position 132 to connect the retrieval device and the support frame connecting position 115, and the bottom is provided with a bottom load-bearing foot 133 of the retrieval device fixed frame.

[0096] like Figure 3As shown, the underwater crushing container for low-yield decommissioned munitions of the present invention involves power supply equipment that can be controlled via an interactive control cabinet 26. Specifically, the interactive control cabinet 26 is powered through a main power supply position 30, and is connected to a signal line extension cabinet 28 via a power line and a signal line 33. The signal line extension cabinet 28 is then connected to the power supply position 34 of the dense net salvage device, the power supply position 35 of the connection device, the 220V power supply position 36, and the power supply position 37 of the belt conveyor. The interactive control cabinet 26 is connected to a frequency converter integrated cabinet 27 via a main power supply position 31 of the frequency converter integrated cabinet. The frequency converter integrated cabinet 27 is connected to the main power supply position 32 of the underwater crushing mechanism via a line. The interactive control cabinet 26 is connected to a water pump control cabinet 29 via a 220V power supply position 36. The water pump control cabinet 29 is connected to multiple water pump power supply positions 39 via a line.

[0097] In this embodiment, the underwater crushing container for low-yield obsolete munitions is used as follows: the belt conveyor 1 transports the low-yield obsolete munitions to be crushed to the inlet 55 of the underwater crushing mechanism 2; the low-yield obsolete munitions are deconstructed in the blade chamber of the underwater crushing mechanism 2; the downstream water control cone 4 guides the deconstructed material into the pot-shaped explosion-proof chamber 5, which is used to trigger the detonation of materials with a probability of detonation in the pot-shaped explosion-proof chamber 5; the U-shaped explosion-proof waterway 7 outside the main water tank 3 further triggers the detonation of the materials with a probability of detonation; the fully deconstructed and detonated material falls into the transfer water tank 8, and is then filtered and retrieved by the dense net retrieval device 11; the retrieved and retrieved material is transported to an external incineration device for incineration, thus completing the entire process of underwater loading, transportation, crushing, detonation, and retrieval of low-yield obsolete munitions, realizing a complete automated control process, improving the efficiency of obsolete munitions disposal, and reducing the operational risks associated with the disposal of obsolete munitions.

[0098] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
