Description

Technical Field

[0001] This utility model relates to the field of underwater blasting technology, and in particular to an underwater blasting detonation device with signal indication function. Background Technology

[0002] Underwater blasting and land blasting operate on roughly the same principle: using the energy released by explosives to loosen, break, and throw away rock and soil. They are primarily used for widening and deepening riverbeds and ports, removing reefs, demolishing underwater structures, and constructing underwater tunnel inlets. Underwater blasting detonators are devices used to trigger the explosion of underwater explosives. Their function is to accurately and safely convert the chemical energy of the explosives into explosive energy to achieve the predetermined underwater blasting objectives.

[0003] Underwater blasting detonation devices typically include a signal transmitter and a signal receiver. The signal transmitter consists of a signal transmitting device, a receiving device, a watertight cable, a power supply, and a transmission control box, and is used to transmit acoustic coded signals. The signal receiver includes a receiving transducer, a signal detection module, a detonation signal and delayed detonation output module, a power supply module, and a pressure-resistant housing. It can receive and process signals and also supply power to related modules. Its working principle is as follows: after the signal transmitter enters the water, it transmits acoustic coded signals. The receiving transducer of the signal receiver receives the signals and transmits them to the detection module. If the signal is confirmed to be a detonation signal after processing, the output current detonates the electric detonator.

[0004] In existing technologies, some detonation devices rely primarily on explosive detonation as their core function, lacking adaptability to complex underwater environments and lacking dedicated external protective structures. This leads to the outer casing being easily damaged by water flow impact and mud friction during underwater use, resulting in decreased protective performance. Consequently, internal signal indicating elements, circuit modules, and detonation control components are directly exposed to the harsh underwater environment, making them susceptible to corrosion from waterborne substances and causing malfunctions, thus affecting the accuracy and stability of signal indication. Therefore, to address these shortcomings, an underwater explosive detonation device with signal indication function is proposed to solve the aforementioned problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides an underwater blasting detonator with signal indication function, aiming to improve the problem that some detonation devices in the prior art lack external protective structures.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An underwater blasting detonator with signal indication function includes a protective shell, a protective cover slidably connected to the top of the protective shell, a fixing mechanism fixedly connected to the bottom of the protective cover, a detonating ball placed on the top of the fixing mechanism, and a waterproof mechanism placed on the top of the detonating ball. The fixing mechanism includes a sealing ring a, the top of which is fixedly connected to the bottom of the protective cover. A sensing component is fixedly connected inside the protective cover. Rotating columns are rotatably connected to the four inner sides of the protective shell. Arc-shaped limiting columns are fixedly connected to the outside of the rotating columns. Limiting hole blocks are fixedly connected to the four outer sides of the protective cover. Fixing blocks are fixedly connected to the four inner walls of the protective shell. Arc-shaped support plates are fixedly connected to the outside of the fixing blocks. A bottom placement plate is fixedly connected to the bottom of the protective shell. As a further description of the above technical solution: The sensing component includes a sensor, which is externally fixedly connected to the inside of the protective cover. Multiple sensing wires are fixedly connected to the outside of the sensor, and the other end of each sensing wire is fixedly connected to the outside of the rotating column. As a further description of the above technical solution: The waterproof mechanism includes a sealing cap, the bottom of which is placed on top of the detonating ball. A sealant sponge is fixedly connected inside the sealing cap, and an explosive ball is placed inside the sealant sponge. As a further description of the above technical solution: A signal device is fixedly connected to the top of the sealing cover, and a signal light is fixedly connected to the top of the sealing cover. As a further description of the above technical solution: A sealing ring b is fixedly connected to the top of the detonating ball, and the top of the sealing ring b is in contact with the bottom of the sealing cover. As a further description of the above technical solution: The outer side of the arc-shaped support plate is in contact with the outer side of the detonating ball, and the bottom of the detonating ball is placed on the top of the bottom placement plate; As a further description of the above technical solution: The inner part of the limiting hole block is slidably connected to the outside of the arc-shaped limiting post, and the outer parts of the multiple arc-shaped limiting posts are slidably connected to the four outer sides of the protective shell. As a further description of the above technical solution: The outer side of the limiting hole block contacts the four outer sides of the protective shell, and the inner side of the limiting hole block has a circular hole to facilitate the insertion of the arc-shaped limiting post to lock the protective cover.

[0007] This utility model has the following beneficial effects: 1. In this utility model, by placing the detonating ball inside the protective shell, the bottom of the detonating ball is placed on top of the bottom placement plate, and the upper end of the detonating ball is restricted by the arc-shaped support plate to prevent the underwater impact from damaging the detonating ball. When it sinks to a certain position, the sensor transmits through the sensor line to drive the rotating column to rotate, so that the arc-shaped limiting column cancels the restriction on the limiting hole block, allowing the detonating ball to fall to the blasting location for detonation. This achieves the function of protecting the device and reduces the effect of device failure due to accidental activation.

[0008] 2. In this utility model, by setting the device to be double-layered, the outer layer is sealed and waterproofed by the detonating ball, sealing cover and sealing ring b, and the inner layer of the detonating ball is filled with a sponge to protect and waterproof the outer layer of the explosive ball, a multi-layer waterproof function is achieved, which can extend the service life of the device.

[0011] 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.

[0012] An underwater blasting detonator with signal indication function, as described in reference Figures 1 to 3 The device includes a protective shell 1, which provides a stable installation space and physical protective barrier. A protective cover 2 is slidably connected to the top of the protective shell 1 to close the top opening of the protective shell 1 and prevent dust, moisture, debris and other objects from entering the interior of the protective shell 1. A fixing mechanism 3 is fixedly connected to the bottom of the protective cover 2. The fixing mechanism 3 includes a sealing ring a31. The top of the sealing ring a31 is fixedly connected to the bottom of the protective cover 2. A sensing component 32 is fixedly connected inside the protective cover 2. The sensing component 32 includes a sensor 321, which is used to detect the sinking depth of the device underwater or the environmental parameters of its location. The outside of the sensor 321 is fixedly connected to the inside of the protective cover 2. Multiple sensing lines 322 are fixedly connected to the outside of the sensor 321 to connect the sensor 321 and the rotating column 33 to realize the signal transmission between the two. The other end of the sensing line 322 is fixedly connected to the outside of the rotating column 33. Specifically, the protective shell 1 provides a stable installation space and reliable physical protection, while the protective cover 2 can slide to close its top opening, effectively preventing dust, moisture, and debris from entering the interior and ensuring that the core components of the device are not corroded. The sealing ring a in the fixing mechanism 3 further enhances the sealing performance and improves the waterproof and dustproof performance of the device. The sensor 321 of the sensing component 32 can accurately detect the underwater sinking depth of the device and the environmental parameters of its location. Together with the sensor line 322, it realizes stable signal transmission with the rotating column 33, ensuring real-time and accurate feedback of depth and environmental information. This provides strong support for the precise control and safe detonation of underwater blasting operations, and improves the applicability, stability, and safety of the device in complex underwater environments.

[0013] The protective shell 1 has rotating posts 33 rotatably connected to its four internal sides. These posts rotate to move the arc-shaped limiting posts 34, locking or unlocking the limiting hole blocks 35. The rotating posts 33 are fixedly connected to the outside of the arc-shaped limiting posts 34, which, in conjunction with the limiting hole blocks 35, lock the protective cover 2 to the protective shell 1. The protective cover 2 has limiting hole blocks 35 fixedly connected to its four external sides, providing space for the arc-shaped limiting posts 34 to pass through. The protective cover 2 is fixed by engaging with the arc-shaped limiting posts 34. The outside of the limiting hole blocks 35 contacts the four external sides of the protective shell 1. The inside of the limiting hole blocks 35 has circular holes to facilitate the insertion of the arc-shaped limiting posts 34 to lock the protective cover 2. The outer part is slidably connected to the outside of the arc-shaped limiting post 34. The outer parts of the multiple arc-shaped limiting posts 34 are slidably connected to the four outer sides of the protective shell 1. The inner walls of the protective shell 1 are fixedly connected to the four sides of the fixed block 36, which provides stable support for the arc-shaped support plate 37 and ensures that the arc-shaped support plate 37 can continuously limit the detonation ball 4. The outer part of the fixed block 36 is fixedly connected to the arc-shaped support plate 37, which provides lateral limiting and buffer protection for the detonation ball 4 inside the protective shell 1. The outer part of the arc-shaped support plate 37 is in contact with the outer part of the detonation ball 4. The bottom of the detonation ball 4 is placed on the top of the bottom placement plate 38. The bottom of the protective shell 1 is fixedly connected to the bottom placement plate 38, which provides a stable bottom bearing surface for the detonation ball 4. Specifically, the rotating column 33, together with the arc-shaped limiting column 34 and the limiting hole block 35, can stably lock the protective cover 2 and the protective shell 1, improving the sealing and firmness of their connection. The arc-shaped support plate 37 supported by the fixing block 36 can limit the detonation ball 4 laterally and provide buffer protection to prevent it from shaking and being damaged. The bottom placement plate 38 provides a stable bearing surface for the detonation ball 4. The overall structure ensures the stable placement of the detonation ball 4 inside the protective shell 1, while strengthening the connection reliability between the protective shell 1 and the protective cover 2, improving the overall stability and safety of the device, and making it suitable for use in complex underwater environments.

[0014] Reference Figure 1 , Figure 2 and Figure 4The top of the fixed mechanism 3 is equipped with a detonating ball 4, which serves as the core blasting carrier of the device. The top of the detonating ball 4 is equipped with a waterproof mechanism 5, which includes a sealing cover 51 and a sealing ring b52 to achieve a waterproof seal on the top of the detonating ball 4. A signal device 55 is fixedly connected to the top of the sealing cover 51 to monitor the underwater status of the device in real time. A signal light 56 ​​is fixedly connected to the top of the sealing cover 51 to facilitate operators to quickly judge the status of the device when observing it on the water surface or at close range. The bottom of the sealing cover 51 is placed on the top of the detonating ball 4. A sluice-filling sponge 53 is fixedly connected inside the sealing cover 51. An explosive ball 54 provides flexible cushioning to prevent direct collision and damage between the explosive ball 54 and the shell of the detonating ball 4. The explosive ball 54 is placed inside the sluice-filling sponge 53, and the explosive inside is the source of the blasting energy. A sealing ring b52 is fixedly connected to the top of the detonating ball 4 to fill the gap between the sealing cover 51 and the detonating ball 4. The top of the sealing ring b52 is in contact with the bottom of the sealing cover 51. Specifically, in the waterproof mechanism 5, the sealing cap 51, together with the sealing ring b, can efficiently seal the top of the detonating ball 4. The sizing sponge 53 can flexibly buffer the explosive ball 54, preventing it from colliding and being damaged with the shell of the detonating ball 4, and can also assist in sealing. The signal device 55 monitors the underwater status in real time, and the signal light 56 ​​allows operators to quickly judge the status of the device. As the core blasting carrier, the detonating ball 4, under the protection of the waterproof mechanism 5, not only ensures the stability of itself and the internal explosive ball 54, but also improves the waterproofness and observability of the device, providing a strong guarantee for the safe and precise execution of underwater blasting operations.

[0015] The implementation principle of this application embodiment is as follows: First, the operator places the explosive ball 54 inside the sizing sponge 53, then places the sizing sponge 53 entirely inside the detonating ball 4, and then covers the top of the detonating ball 4 with the sealing cap 51, so that the bottom of the sealing cap 51 is in close contact with the sealing ring b52 on the top of the detonating ball 4, thus completing the internal sealing of the detonating ball 4. Then, the protective cap 2 on the top of the protective shell 1 is opened, and the assembled detonating ball 4 is placed inside the protective shell 1, so that the bottom of the detonating ball 4 is placed stably on the bottom placement plate 38. At the same time, the outside of the detonating ball 4 is in contact with the arc-shaped support plate 37 connected to the fixing block 36, forming a lateral limit on the detonating ball 4. Then, the protective cap 2 is closed, so that the rotating column 33 drives the arc-shaped limiting column 34 to insert into the circular hole of the limiting hole block 35, thereby locking the protective cap 2 and the protective shell 1, and the sealing ring a31 further enhances the sealing performance.

[0016] After the device is submerged in water, sensor 321 detects the sinking depth of the device in real time, and signal device 55 continuously transmits the device status signal. Signal light 56 ​​displays the corresponding light according to the device status, which is convenient for operators to monitor. When the device sinks to the preset blasting position, sensor 321 transmits the signal to rotating column 33 through sensor line 322, causing rotating column 33 to rotate. This causes arc-shaped limiting column 34 to slide out from the circular hole of limiting hole block 35, releasing the lock on protective cover 2. Thus, protective cover 2 separates from protective shell 1 under underwater pressure. The detonating ball 4, which is no longer restricted, falls from protective shell 1 to the blasting location. Subsequently, explosive ball 54 detonates, completing the underwater blasting operation.

[0017] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
