During testing, various factors, such as electromagnetic interference from testing equipment, static electricity buildup, unexpected electrical signal fluctuations, or improper operation by personnel, can trigger the detonator's initiation device, leading to premature detonation. Premature detonation poses a direct and serious threat to the lives of on-site testing personnel, potentially causing irreparable casualties. Furthermore, premature detonation can severely damage surrounding testing equipment and facilities. Therefore, ensuring the safety of electronic detonator testing is a critical technical problem that urgently needs to be solved in this field. Utility Model Content

Detailed Implementation

[0017] refer to Figure 1 and Figure 2 A device for detecting premature detonation debris and blocking explosion energy from electronic detonators includes a housing 1, a cover plate 4, a blocking and energy-dissipating cylinder 2, and an attitude-constraining cylinder 3.

[0018] refer to Figures 1-5 The top of the housing 1 is open, and a cover plate 4 is installed at the opening to seal it. A lead wire guide hole 105 is provided on one side of the housing 1 for the lead wire of the electronic detonator to pass through. The top of the blocking energy release cylinder 2 is open, and a slot 101 is provided at the bottom of the housing 1. The blocking energy release cylinder 2 is inserted into the slot 101. The side wall of the blocking energy release cylinder 2 has several conical energy release holes 202, which are larger inside and smaller outside, to absorb and release the energy after premature detonation of the detonator. The attitude restraint cylinder 3 is used to hold the electronic detonator and is inserted into the blocking energy release cylinder 2. As is easily understood, the attitude restraint cylinder 3 also has a cylindrical structure with an open top.

[0019] In practical applications, the blocking energy release cylinder 2 serves as the first layer of protection, capable of withstanding the first impact. The conical energy release hole 202 absorbs and releases the energy after premature detonation of the detonator, and then forms an additional physical protection (second layer of protection) through the housing 1. Even if the blocking energy release cylinder 2 is damaged in an accident, the housing 1 can still play a protective role. Overall, it can effectively prevent energy leakage and debris damage during premature detonation in the detection process, providing core safety assurance for the detection process.

[0020] refer to Figure 1 , Figure 3 and Figure 8 In this embodiment, the cover plate 4 is installed as follows: one side of the housing 1 is provided with an insertion port 103, and the other three sides of the housing 1 are provided with constraint grooves 104. The cover plate 4 is inserted into the constraint grooves 104 through the insertion port 103, and the constraint grooves 104 restrict the position of the cover plate 4. Furthermore, one side of the cover plate 4 is provided with a gripping part 401, which facilitates the operator to remove the cover plate 4 after the inspection is completed. In this embodiment, the gripping part 401 has a downward bending structure. In some embodiments, the gripping part 401 may also have an upward bending structure. In other embodiments, the gripping part 401 may of course have other structures.

[0021] In this embodiment, both the housing 1 and the cover plate 4 are made of fiberglass, which features lightweight, high strength, strong impact resistance, corrosion resistance, and antistatic properties. The cover plate 4 is 5mm thick, and the overall dimensions of the housing 1 are 400mm × 330mm × 150mm, with a wall thickness of 5mm. Handles 108 are provided on both opposite sides of the housing 1 for easy carrying. The housing 1 is compact, and the entire device can be assembled on-site, allowing operators to easily carry it into various complex working environments, significantly improving the flexibility and mobility of the testing work. The energy release cylinder 2 is made of low-carbon steel, providing good impact resistance. Its dimensions are φ52mm × 4mm, with a length of 300mm and a tapered energy release hole 202 with an outer diameter of 5mm and an inner diameter of 10mm. The attitude restraint cylinder 3 is made of polyvinyl chloride, which features easy molding, corrosion resistance, and antistatic properties. Its inner diameter is 10mm and its length is 165mm.

[0022] refer to Figure 2 In this embodiment, several slots 101 are provided to facilitate the insertion of several blocking energy release cylinders 2. For example, ten slots 101 can hold ten blocking energy release cylinders 2 at a time. A fixing bolt 201 is provided on the bottom side of the blocking energy release cylinder 2. The fixing bolt 201 has a block-like structure. The side wall of the slot 101 has a fixing groove 102 to accommodate the fixing bolt 201. The circumferential dimension of the fixing groove 102 can be slightly larger than the circumferential dimension of the fixing bolt 201, for example, 0.1-0.2 mm larger. In practical applications, the bolt is constrained by the fixing groove 102, limiting the large-scale rotation of the blocking energy release cylinder 2. Alternatively, in this embodiment, the slot 101 is formed by a protruding structure located at the bottom of the housing 1. The material of the protruding structure and the fixing bolt 201 are both polyvinyl chloride, which has characteristics such as easy molding, corrosion resistance, and antistatic properties. In this embodiment, the fixing groove 102 is a notch in the side wall of the protruding structure. In other embodiments, the fixing groove 102 may not be a notch, but rather a groove located on the inner wall of the protruding structure.

[0023] refer to Figure 2 , Figure 6 and Figure 7 In this embodiment, the attitude constraint cylinder 3 is installed as follows: The attitude constraint cylinder 3 has latches 301 on both sides of its top. The latches 301 are engaged with the top edge of the blocking energy discharge cylinder 2. In practical applications, the latches 301 on both sides are symmetrically arranged to constrain the attitude constraint cylinder 3 to the center of the blocking energy discharge cylinder 2. Different models and specifications of portable electronic detonators can be placed in the attitude constraint cylinder 3, giving this device wide adaptability and a broader range of applications. Furthermore, it should be understood that the distance between the top of the attitude constraint cylinder 3 and the cover plate 4 should be less than the depth of the slot 101 to prevent the blocking energy discharge cylinder 2 and the attitude constraint cylinder 3 from disengaging from the slot 101.

[0024] A gap exists between the bottom of the attitude restraint cylinder 3 and the bottom of the blocking energy release cylinder 2. The bottom of the attitude restraint cylinder 3 has a drain hole 302, and the bottom of the housing 1 has a drain hole 106. Support feet 107 are located on the bottom surface of the housing 1. In practical applications, four support feet 107 are provided, located at the four corners of the housing 1. It is worth noting that the support feet 107 allow the bottom surface of the housing 1 to be suspended in the air. If water enters the attitude restraint cylinder 3, the water can be discharged from the housing 1 sequentially through the drain hole 302, the conical energy release hole 202, and the drain hole 106. It should be understood that the gap between the bottom of the attitude restraint cylinder 3 and the bottom of the blocking energy release cylinder 2 should be greater than the distance from the bottom of the blocking energy release cylinder 2 to the bottommost conical energy release hole 202 to prevent water from accumulating in the attitude restraint cylinder 3.

[0025] Based on the above, the assembly method of this device in practical application is as follows: First, assemble the blocking energy discharge cylinder 2 and the attitude constraint cylinder 3, that is, snap the buckles 301 on both sides of the attitude constraint cylinder onto the top side edge of the blocking energy discharge cylinder 2, so that the attitude constraint cylinder 3 is located in the center of the blocking energy discharge cylinder 2. Then, insert the ten components (i.e., the whole formed by the blocking energy discharge cylinder 2 and the attitude constraint cylinder 3) into the slots 101 at the bottom of the housing 1, and lock the blocking energy discharge cylinder 2 in place by the fixing bolts 201 on the side of the blocking energy discharge cylinder 2 into the fixing grooves 102 on the side wall of the slot 101. When testing the electronic detonator, place the electronic detonator with the energy-concentrating hole facing down in each attitude constraint cylinder, and let the lead wire pass through the lead wire guide hole 105 on the housing 1. Finally, insert the cover plate 4 into the constraint groove 104 from the insertion port 103 to complete the assembly of the device, and the electronic detonator can be charged and tested.

[0026] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
