Description

Technical Field

[0001] This utility model relates to the field of pipeline connection technology, specifically to an easily disassembled explosion safety protection device. Background Technology

[0002] Blasting utilizes the energy generated by explosives to disrupt materials such as water, air, or soil and rock, causing them to loosen, compress, and deform. As an effective means of rapidly breaking concrete and rock, blasting is widely used in construction engineering. This method is often used to demolish metal buildings or in earthwork projects. However, because blasting produces hazardous effects such as flying debris and shock waves, safety measures are necessary to protect workers. Currently, common protective devices involve erecting tents or other structures at a safe distance, but this method is complex in structure, time-consuming, inconvenient to transport, and cannot control dust pollution after blasting.

[0003] Therefore, in order to improve the existing problems, a prefabricated blasting safety protection device that is easy to disassemble and can be quickly assembled on site is proposed. Utility Model Content

[0004] To address the problems of complex structure, long construction period, and inconvenient transportation and installation of existing protective devices, this utility model provides an easily disassembled blasting safety protection device.

[0028] Example 1

[0029] The technical solution of this utility model is as follows:

[0030] See Figure 1 An easily detachable blasting safety protection device, comprising:

[0031] The protective cylinder 1 is formed by multiple baffles 11 being spliced ​​together in sequence. Several plug-in components 12 are provided on the side of the baffles 11 to splice with adjacent baffles 11. Several vertically arranged reinforcing ribs 13 are arranged in an array on the outer surface of the baffles 11. The horizontal cross-section is arc-shaped. A protective net 14 is provided inside the protective cylinder 1.

[0032] The top cover 2 is a frustum structure with a diameter that gradually increases from top to bottom. It has an opening at the top, a cavity in the middle, and is installed at the bottom of the protective cylinder 1. Several sensor mounting holes 21 are provided on the side.

[0033] There are two baffles 11 of the same size. Each layer uses metals and materials of different strengths to effectively increase or decrease the level of safety protection. Depending on the specific circumstances and safety requirements of the blasting operation, baffles 11 of appropriate strength and material are selected for splicing. For example, in cases of large-scale blasting with high risk, high-strength, high-toughness baffle 11 materials can be selected to improve the protective capability of the protective cylinder 1; in cases of small-scale blasting with low risk, relatively lower-strength but lower-cost baffle 11 materials can be selected to reduce the cost of the device. This adjustability allows the device to adapt to different blasting scenarios, improving its applicability and economy.

[0034] This modular structure allows the protective cylinder 1 to be disassembled into multiple independent baffles 11 during transportation and storage, greatly reducing space occupation and facilitating transportation and handling. Furthermore, during on-site installation, the protective cylinder 1 can be quickly assembled simply by sequentially assembling the baffles 11, improving installation efficiency.

[0035] The plug-in assembly 12 includes plug-in holes and plug-in protrusions, and has a circular vertical cross-section. The baffle 11 has four plug-in holes or protrusions on one side, such as... Figure 2 As shown, the radius is 3cm. The axis of the plug-in assembly 12 is perpendicular to the axis of the protective cylinder 1.

[0036] The circular cross-section makes the insertion assembly 12 smoother during the insertion process, reduces friction during insertion, and improves installation efficiency. At the same time, the circular cross-section also has good stress-bearing capacity and can withstand greater insertion forces.

[0037] After insertion, they form a circular cylindrical protective cylinder 1, which is compatible with the shape of the explosive. This reduces blind spots and improves the protective effect. At the same time, the arc-shaped structure also helps to disperse the impact force generated by the blast, enhancing the overall stability of the protective cylinder 1.

[0038] The plug-in assembly 12 enables quick connection and disassembly between the baffles 11. The operation is simple and convenient, requiring no complicated tools or professional skills, thus reducing the difficulty and cost of installation and disassembly.

[0039] The protective net 14 is fitted onto the protrusions between the baffles 11 and is made of high-strength metal.

[0040] The protective net 14 can further block small flying stones and fragments generated by the blast. At the same time, the protective net 14 can also play a certain buffering role, reducing the impact of the impact on the baffle 11.

[0041] The horizontal cross-section of reinforcing rib 13 is arc-shaped.

[0042] Furthermore, the reinforcing rib 13 protrudes 10cm outward from the baffle 11. If the protrusion is too large, the processing cost will be high and the installation will be laborious. If the protrusion is too small, the strength will be insufficient and it will not play a role in strengthening the baffle 11.

[0043] The reinforcing ribs 13 can significantly enhance the structural strength of the baffle 11 and improve its impact resistance. During blasting, when flying rocks or shock waves hit the baffle 11, the reinforcing ribs 13 can effectively disperse and withstand the impact force, preventing the baffle 11 from deforming or being damaged, thereby ensuring the overall protective performance of the protective cylinder 1.

[0044] The baffle 11 and the reinforcing rib 13 are integrated into a single structure. This integrated structure makes the connection between the baffle 11 and the reinforcing rib 13 more robust, eliminating any gaps and improving the overall strength and stability. At the same time, the integrated structure also reduces processing steps and costs, increasing production efficiency.

[0045] The top cover 2 is made of high-strength metal.

[0046] Furthermore, the sensor mounting opening of the top cover 2 can be adjusted according to the sensor size. The sensor mounting hole 21 provides mounting positions for various sensors, facilitating real-time monitoring of blasting parameters such as vibration and shock wave intensity during blasting, and providing data support for safety assessment and control of blasting operations.

[0047] Furthermore, in practical applications, the bottom of the top cover 2 is provided with a connecting post, and the upper surface of the protective cylinder 1 has a groove for insertion into the connecting post. After insertion, it is as follows: Figure 3 As shown, the explosive power of the explosive is insufficient to blast the sensor out of the top cover 2.

[0048] This truncated cone structure design gives the top cover 2 good stability and wind resistance, enabling it to remain stable under the complex environmental conditions of the blasting site and preventing it from being blown over or displaced by the wind.

[0049] The top cover 2 has an opening at the top and a cavity in the middle. See [reference needed]. Figure 4 The upper opening can be used for ventilation, exhaust, and observation of the explosion, and can also serve as one of the installation locations for sensors. The design of the central cavity reduces the weight of the top cover 2, lowers material costs, and also facilitates installation and maintenance.

[0050] In use, the two baffles 11 are connected to form a protective cylinder 1 through the plug-in assembly 12, the top cover 2 is placed on the protective cylinder 1, and then the entire device is fixed in the blasting area.

[0051] This utility model's easily detachable, modular blasting safety protection device can be quickly assembled and deployed on-site in blasting areas, providing good protection and high efficiency. The double-sided baffles 11 and internal protective net 14 further reduce the impact force and dissipate energy. At the same time, the top sensor can detect blasting data.

[0052] Example 2

[0053] Considering that if the explosive force is too great during the blasting process, the top cover may be blown off, the connection between the top cover 2 and the protective cylinder 1 in Embodiment 1 is designed as a rotating snap-fit ​​connection to better solve the problem.

[0054] Specifically, the bottom surface of the top cover 2 is provided with several L-shaped snap-fit ​​protrusions at intervals. The corners are located on the side near the center of the top cover 2. It is divided into a vertical part and a horizontal part, which are vertically connected and integrally formed. The top of the vertical part is connected to the bottom surface of the top cover 2, and the horizontal part extends outward.

[0055] See Figure 5 The top edge of the protective cylinder 1 has several inverted L-shaped baffles spaced apart, with the openings facing inwards, such as... Figure 6 As shown in the image.

[0056] In use, the horizontal part is inserted into the interface, and the top cover 2 is rotated to make the horizontal part rotate along the slide rail, thus completing the locking. This connection method is more secure and can protect the top cover 2 from being blown away during the use of the device.

[0057] All other structures not mentioned are the same as in Example 1.
