An underwater blasting charging device

Abstract

This utility model discloses an underwater blasting charging device, including a storage cylinder. An annular block is fixedly connected to the middle of the bottom end of the storage cylinder. Connecting mechanisms are provided on both sides inside the storage cylinder. A float plate is provided at the middle of the bottom end of the storage cylinder. An inflation mechanism is provided on one side of the storage cylinder, and a safety airbag is provided on one side of the inflation mechanism. A storage cavity is provided at the middle of the top end of the storage cylinder. This utility model, by providing an inflation mechanism inside the storage cylinder, allows the safety airbag in the bottom storage cylinder to be inflated first when an external air pump inflates the underwater charging device due to the siphon effect of the U-shaped tube inside the inflation mechanism. The inflated safety airbag then pulls a square block via a pull rope, causing the square block to pull a magnetic rod out of the positioning hole on the annular block at the bottom of the storage cylinder. At this point, the bottom storage cylinder can quickly detach from the entire charging device due to gravity.

Description

Technical Field

[0001] This utility model relates to the field of underwater blasting technology, specifically to an underwater blasting charging device. Background Technology

[0002] Underwater blasting explosive charging devices are engineering equipment specifically designed for underwater blasting operations. They typically consist of high-energy explosives and a pressure-resistant sealed casing. They are widely used in areas such as clearing underwater obstacles in canals, excavating rock strata, dismantling sunken ships, laying oil and gas pipelines, and destroying military targets. They are characterized by high energy density, precise detonation, and strong environmental adaptability.

[0003] An air-spaced explosive charging device for underwater blasting, disclosed in Chinese Patent Publication No. CN217738061U, utilizes a long bag to form a fixed space within a bamboo-joint tube. This bamboo-joint structure allows for the creation of multiple air-spaced explosive bodies. A sealing layer further seals the internal detonating cord and explosives within a sealed space. During transport to the detonation port in deep water, the sealing layer provides both sealing protection and shock-absorbing airbags to buffer external forces, preventing the long bag and the bamboo-joint tubes inside from being affected by external forces and thus ensuring effective detonation. However, the charging device has fixed overall specifications, resulting in low flexibility and an inability to be quickly disassembled and used underwater according to the actual blasting needs of the canal. This leads to waste of explosive materials and a large-scale impact on the underwater environment. Utility Model Content

[0004] The purpose of this invention is to provide an underwater blasting charging device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an underwater blasting charging device, comprising a storage cylinder, an annular block fixedly connected to the middle position of the bottom end of the storage cylinder, connecting mechanisms provided on both sides inside the storage cylinder, a float plate provided at the middle position of the bottom end of the storage cylinder, an inflation mechanism provided on one side inside the storage cylinder, a safety airbag provided on one side of the inflation mechanism, a storage cavity provided at the middle position of the top end inside the storage cylinder, and a sealing mechanism provided on one side of the bottom end of the inflation mechanism.

[0006] Preferably, the top of the storage cylinder is provided with hanging ears on both sides, the top of the storage cavity is provided with a sealing cap on one side, and the detonator is installed in the middle of the top of the storage cavity.

[0007] Preferably, the connecting mechanism includes an annular groove inside the top of the storage cylinder that engages with the annular block, positioning holes inside both sides of the annular block, movable chambers on both sides of the top of the storage cylinder, and a rotating shaft rotatably connected to one side of the movable chamber.

[0008] Preferably, a square block is slidably connected to one side of the interior of the active compartment, a magnetic rod that engages with a positioning hole is fixedly connected to one side of the square block, and a pull rope whose bottom end is fixedly connected to a float plate is fixedly connected to the side of the square block away from the magnetic rod.

[0009] Preferably, the inflation mechanism includes a connector fixedly connected to one side of the top of the storage cylinder, an air supply pipe with its top end communicating with the connector is provided on one side inside the storage cylinder, and a U-shaped pipe with one side communicating with the airbag is provided at the bottom end of one side of the air supply pipe.

[0010] Preferably, the sealing mechanism includes a rubber head that is slidably connected to the bottom end of one side of the gas delivery pipe, a movable block that is fixedly connected to one side of the rubber head, and a spring that is fixedly connected to one side of the movable block.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This underwater blasting charging device has an inflation mechanism inside the storage cylinder. When an external air pump inflates the charging device for underwater operations, the siphon effect of the U-shaped tube inside the inflation mechanism first inflates the safety airbag in the bottom storage cylinder. At this time, the inflated safety airbag can pull the square block through the pull rope, and the square block will drive the magnetic rod to be pulled out from the positioning hole on the annular block at the bottom of the storage cylinder. At this time, the bottom storage cylinder can be quickly separated from the charging device by gravity and deployed to the designated underwater blasting position. At the same time, the number of charging devices used can be quickly adjusted according to the actual blasting specifications, improving the overall functionality and subsequent use effect of the charging device.

[0013] 2. This underwater blasting charging device has an annular groove and an annular block at the top and bottom of the storage cylinder, respectively. When the annular block on the storage cylinder is inserted into the annular groove at the top of the storage cylinder, the magnetic force of the magnetic rod can quickly insert into the positioning hole on the annular block, thus completing the rapid assembly of the charging device. The operation is simple and convenient, and the modular design improves the flexibility of subsequent use of the charging device and reduces the loss of blasting resources.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides two technical solutions:

[0021] Example 1: An underwater blasting charging device includes a storage cylinder 1, an annular block 2 fixedly connected to the middle of the bottom end of the storage cylinder 1, connecting mechanisms 3 on both sides inside the storage cylinder 1, a float 4 at the middle of the bottom end inside the storage cylinder 1, an inflation mechanism 5 on one side inside the storage cylinder 1, a safety airbag 6 on one side of the inflation mechanism 5, a storage cavity 7 at the middle of the top end inside the storage cylinder 1, and a sealing mechanism 8 on one side of the bottom end inside the inflation mechanism 5. The storage cavity 7 can store blasting explosives. The outer shell of the storage cylinder 1 is made of corrosion-resistant gold material to ensure stable operation in high-pressure and humid environments.

[0022] The storage cylinder 1 has two hanging lugs 101 on both sides of its top end, and a sealing cover 701 is provided on one side of the top end of the storage chamber 7. A detonator 702 is installed in the middle of the top end inside the storage chamber 7. The hanging lugs 101 facilitate the use of external lifting equipment such as cranes to lower the charging device underwater for installation. The sealing cover 701 can effectively seal the inside of the storage chamber 7. At the same time, the detonator 702 is a waterproof electronic detonator with a built-in micro circuit, which triggers the detonation through an electrical signal.

[0023] The connecting mechanism 3 includes an annular groove 102 inside the top of the storage cylinder 1 that engages with the annular block 2, positioning holes 201 inside both sides of the annular block 2, and movable chambers 103 on both sides of the top of the storage cylinder 1. A rotating shaft 104 is rotatably connected to one side inside the movable chamber 103. The annular block 2 is made of waterproof iron to facilitate the adsorption of the magnetic rod 302. When the annular block 2 on the storage cylinder 1 is inserted into the annular groove 102 on the storage cylinder 1, and the magnetic rod 302 is inserted into the positioning hole 201 on the annular block 2 through the annular groove 102, the assembly of the same type of drug loading device can be completed.

[0024] A square block 301 is slidably connected to one side of the interior of the active chamber 103. A magnetic rod 302 that engages with the positioning hole 201 is fixedly connected to one side of the square block 301. A pull rope 401 whose bottom end is fixedly connected to the side of the square block 301 away from the magnetic rod 302 is fixedly connected to the side away from the magnetic rod 302. When the float 4 moves downward, the float 4 can pull the square block 301 through the pull rope 401. At this time, the square block 301 can drive the magnetic rod 302 to be pulled out from the positioning hole 201 on the annular block 2 and separate the storage cylinders 1 of the same type. When the storage cavity 7 inside the storage cylinder 1 is empty, rotating the storage cylinder 1 as a whole will cause the square block 301 and the magnetic rod 302 to be drawn into the interior of the storage cylinder 1 due to the centrifugal force generated by the rotation of the storage cylinder 1, thus facilitating the subsequent engagement with the annular block 2 at the bottom of the storage cylinder 1 of the same type.

[0025] Example 2 differs from Example 1 mainly in that:

[0026] An underwater blasting charging device includes an inflation mechanism 5 comprising a connector 501 fixedly connected to one side of the top of a storage cylinder 1. An air supply pipe 502, whose top end communicates with the connector 501, is provided on one side inside the storage cylinder 1. A U-shaped tube 503, whose bottom end communicates with a safety airbag 6, is provided on one side of the air supply pipe 502. The connector 501 can be easily inserted into the air supply pipe 502 at the bottom of a similar storage cylinder 1. At this time, an external air pump can inflate the safety airbag 6 through the air supply pipe 502 and the U-shaped tube 503. Simultaneously, the U-shaped tube 503 allows gas to preferentially enter the safety airbag 6 inside the bottommost storage cylinder 1 during inflation.

[0027] The sealing mechanism 8 includes a rubber head 801 slidably connected to the bottom end of one side of the air supply pipe 502. A movable block 802 is fixedly connected to one side of the rubber head 801, and a spring 803 is fixedly connected to one side of the movable block 802. When the rubber head 801 is subjected to an upward force, the movable block 802 can compress the spring 803, at which time the rubber head 801 can be retracted into the storage cylinder 1. When the connector 501 is pulled out from the bottom end of the air supply pipe 502, the reaction force of the spring 803 being compressed can push the rubber head 801 through the movable block 802 to perform the sealing work at the bottom end of the air supply pipe 502. At the same time, the contents not described in detail in this specification are all prior art known to those skilled in the art.

[0028] In use, according to this embodiment: by opening the sealing cover 701, the explosive to be blasted can be loaded into the storage cavity 7, and the explosive is sealed by the sealing cover 701. At the same time, by inserting the annular block 2 at the bottom of the storage cylinder 1 into the annular groove 102 at the top of the storage cylinder 1, the magnetic rod 302 inside the bottom storage cylinder 1 can be inserted into the positioning hole 201 on the annular block 2, thus completing the assembly of the explosive loading device. After the external cable is wrapped around the lug 101, it can be lifted by a lifting device. The loading device is moved and transported, and then placed in a designated position in the canal. At the same time, an external air pump can inflate the air supply pipe 502 through the connector 501. At this time, the safety airbag 6 in the bottom storage cylinder 1 inflates and pushes the float 4 downward. The pull rope 401 on the float 4 can pull the square block 301 through the rotating shaft 104, and the square block 301 drives the magnetic rod 302 to be pulled out from the positioning hole 201 on the ring block 2. At this time, the bottom storage cylinder 1 can be divided and sunk due to gravity.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
