Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic detonator technology, and in particular to an anti-parasitic detonation device that can be used for detecting the propellant head of a wireless electronic detonator. Background Technology
[0002] Before use, wireless electronic detonator heads need to be tested to ensure they function properly. Current testing methods mostly involve placing multiple wireless electronic detonator heads in a row, each in contact with a probe, and using the probe to test whether the heads are functioning correctly.
[0003] However, since there are multiple wireless electronic detonator heads in a row (usually 10 in a row), when one of the wireless electronic detonator heads detonates sympathetically, the high temperature will affect the adjacent wireless electronic detonator heads, thus causing damage to the adjacent wireless electronic detonator heads. Utility Model Content
[0004] The present invention provides a device for preventing sympathetic detonation that can be used for detecting the propellant head of a wireless electronic detonator, aiming to solve the above-mentioned technical problems.
[0005] This utility model provides a sympathetic detonation prevention device for detecting the propellant head of a wireless electronic detonator, comprising:
[0006] The housing has multiple through holes arranged along the wireless electronic detonator heads. A partition device is provided between the through holes so that when the housing covers a row of wireless electronic detonator heads, the positions of the wireless electronic detonator heads correspond to the through holes, and the wireless electronic detonator heads are separated from each other by the partition device.
[0007] In some feasible embodiments, the housing is made of a flame-retardant material.
[0008] In some possible implementations, the housing is an aluminum alloy housing.
[0009] In some possible implementations, the housing is a rectangular housing with multiple rows of through holes arranged along its width, the multiple rows of through holes being spaced at a preset distance.
[0010] In some feasible methods, the multiple rows of through holes are spaced at a preset distance, and the corresponding housing has a hollow structure to allow observation of the internal conditions.
[0011] In some feasible embodiments, the multiple rows of through holes are spaced at a preset distance, and the corresponding housing has a transparent window to allow observation of the interior.
[0012] In some possible implementations, the partition device is a baffle plate disposed on the inner wall of the housing between adjacent through holes and perpendicular to the inner wall of the housing; the height of the baffle plate is equal to or less than the thickness of the housing.
[0013] In some possible implementations, one end of the baffle is inserted into the inner wall of the housing.
[0014] In some possible implementations, the partition device is a cylindrical structure, one end of which is connected to the edge of the through hole so that the cylindrical structure can be fitted onto the head of the wireless electronic detonator.
[0015] In some feasible embodiments, the cylindrical structures corresponding to adjacent through holes are connected and share a common cylindrical wall.
[0016] The beneficial effects of this utility model are as follows: This application provides an anti-parasitic detonation device for detecting wireless electronic detonator heads, comprising a housing with multiple through holes arranged along the wireless electronic detonator heads; a partition device is provided between the through holes so that when the housing covers a row of wireless electronic detonator heads, the positions of the wireless electronic detonator heads correspond to the through holes, and the wireless electronic detonator heads are separated from each other by the partition device. Through this structure, while covering the wireless electronic detonator heads arranged in a row, adjacent wireless electronic detonator heads can also be separated, preventing the parasitic detonation of one wireless electronic detonator head from affecting adjacent wireless electronic detonator heads.

[0023] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0024] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0025] 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 indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified. Furthermore, the terms "installed," "connected," and "linked" should be interpreted broadly; for example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0026] like Figure 1 and Figure 2 As shown, this application provides a sympathetic detonation prevention device for detecting wireless electronic detonator heads, including a housing 1 with a plurality of through holes 11 arranged along the wireless electronic detonator heads 2; a partition device 12 is provided between the through holes 11 so that when the housing 1 covers a row of wireless electronic detonator heads 2, the positions of the wireless electronic detonator heads 2 correspond to the through holes 11, and the wireless electronic detonator heads 2 are separated from each other by the partition device 12.
[0027] It should be noted that the through hole 11 allows for convenient observation of the state of the wireless electronic detonator head 2 during testing, such as whether a secondary detonation has occurred.
[0028] The shape of the housing 1 can be set as needed. When multiple rows of wireless electronic detonator heads 2 are detected simultaneously, the shape of the housing 1 can be constructed according to the arrangement of the multiple rows of wireless electronic detonator heads 2, such as a rectangle. When there is only one row of wireless electronic detonator heads 2, the shape of the housing 1 can be a rectangle or a special shape of a rectangle, such as a square.
[0029] It should be noted that if the housing 1 is rectangular, multiple rows of through holes 11 are arranged along its width, with the rows of through holes 11 spaced at a predetermined distance. That is, each row of through holes 11 is arranged along the width of the housing 1, and the number of through holes 11 in each row corresponds to the number of wireless electronic detonator heads 2 in each row. In this way, one housing 1 can be used for multiple rows of wireless electronic detonator heads 2 for synchronous detection.
[0030] Since the function of the housing 1 is to prevent the wireless electronic detonator head 2 from detonating during testing, the housing 1 needs to be constructed of flame-retardant material. For example, the housing 1 is made of aluminum alloy. Furthermore, the partition device 12, which serves as a barrier or isolation device, is also made of flame-retardant material. For example, it is made of the same aluminum alloy as the housing 1. However, it is also possible to choose a different material than the housing 1 as needed. This application does not limit this choice.
[0031] In one embodiment, the multiple rows of through holes 11 are spaced at a preset distance, and the corresponding housing 1 has a hollow structure to allow observation of the internal conditions.
[0032] Before the wireless electronic detonator head 2 is inspected, it is separated from the probe and positioned above the probe, either normally or at an angle. Once the wireless electronic detonator head 2 moves towards and contacts the probe, it can be inspected through the probe. During this process, the through-hole 11 not only serves an observation function but also accommodates the vertical movement of the wireless electronic detonator head 2.
[0033] However, when observing through the through hole 11, since there is still a certain distance between the through hole 11 and the contact position of the probe and the wireless electronic detonator head 2, the edge of the through hole 11 may obstruct the view of the staff. Therefore, the wall of the housing 1 between the two rows of through holes 11 is designed to be hollow, so that the wireless electronic detonator head 2 inside the housing 1 can be observed through the hollow holes.
[0034] The size of the perforated holes can be set as needed, and this application does not limit it.
[0035] Furthermore, to prevent splashing during the secondary explosion and ejection through the perforated holes, transparent windows can be provided on the housing 1 at preset intervals between the multiple rows of through holes 11 to allow observation of the internal conditions.
[0036] It should be noted that the transparent window can be fire-resistant glass, embedded in the housing 1, so that the interior of the housing 1 can be observed through the transparent window. The size of the fire-resistant glass can be adjusted as needed, and this application does not limit it. The fire-resistant glass can be composed of one or more pieces of glass, and this application does not limit it either.
[0037] In one embodiment, the partition device 12 is a baffle plate disposed on the inner wall of the housing 1 between adjacent through holes 11 and perpendicular to the inner wall of the housing 1; the height of the baffle plate is equal to or less than the thickness of the housing 1.
[0038] Specifically, the baffle is a sheet-like interface, with a height equal to or less than the thickness of the housing 1, and a width equal to or greater than the length of the through hole 11. That is, if the through hole 11 is a circular hole, the width of the baffle is equal to the diameter of the circular hole; if the through hole 11 is an ellipse, the width of the baffle is equal to its major axis. It should be noted that the width of the baffle is at least equal to the outer diameter of the wireless electronic detonator head 2 to ensure that it can form a shield for adjacent wireless electronic detonator heads 2.
[0039] It should be noted that the baffle and the housing 1 can be an integral or separate structure. When the baffle and the housing 1 are separate structures, the housing 1 has a recessed slot corresponding to the position of the baffle. In this way, one end of the baffle can be inserted into the slot to fix the baffle to the housing 1. In addition, the recessed slot can also be designed to protrude from the slot of the housing 1 according to the thickness of the housing 1. Similarly, the baffle is inserted into the slot protruding from the housing 1 to complete the relative fixation with the housing 1. This structure makes it convenient to adjust the number of baffles at any time to accommodate the number of wireless electronic detonator heads 2.
[0040] In one embodiment, the partition device 12 is a cylindrical structure, one end of which is connected to the edge of the through hole 11 so that the cylindrical structure can be fitted onto the wireless electronic detonator head 2.
[0041] Specifically, a cylindrical structure is used to axially enclose the wireless electronic detonator head 2, thus maximizing the safety of adjacent wireless electronic detonator heads 2. The cylindrical structure is a cylindrical body, with one end connected to the edge of the through hole 11. This connection can be integral or separate. When the cylindrical body and the through hole 11 are separate, the outer diameter of the cylindrical body can be designed to be slightly smaller than the inner diameter of the through hole 11, facilitating insertion of the cylindrical body into the through hole 11. Furthermore, an outer edge is provided at one end of the cylindrical body. When the cylindrical body is inserted into the through hole 11, the outer edge can fix it to the edge of the through hole 11. Additionally, the cylindrical body and the through hole 11 can be designed with an interference fit, ensuring relative fixation between the cylindrical body and the through hole 11.
[0042] In the above structure, the cylindrical bodies are independent structures. Alternatively, the cylindrical bodies can also be a continuous structure, as described below:
[0043] The cylindrical structures corresponding to adjacent through holes 11 are connected and share a common cylindrical wall. That is, when the cylindrical body is a connected structure, the cylindrical body walls between adjacent through holes 11 are shared, and the multiple cylindrical bodies corresponding to a row of through holes 11 are a single-piece structure. In this way, the cylindrical body and the edge of the through hole 11 are integrally formed.
[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
