Description

Technical Field

[0001] This utility model relates to the field of rock blasting technology in mining geology, specifically a rock blasting device for mining geology. Background Technology

[0002] In modern mining and rock blasting, remote-controlled detonators are commonly used. These devices detonate explosive charges from a distance using radio waves, sound waves, or light beams. They typically consist of a transmitter and a receiver, capable of simultaneously and accurately detonating multiple charges or detonating them one by one. However, some existing remote-controlled detonators for breaching have certain inconveniences in use, making it difficult to lock the control keys and prone to accidental activation, leading to safety hazards and significant losses.

[0003] Patent CN223154124U discloses a handheld wireless detonator with an anti-accidental activation structure. Through the design of a positioning structure and elastic support, when the detonation button is pressed by an external force due to accidental activation, the button causes the abutment to slide. Because the positioning structure is not properly fitted, the downward sliding distance of the abutment is less than the distance between the movable and fixed trigger plates, thus failing to generate a detonation signal. This effectively prevents accidental activation, and the mechanism is stable and reliable, preventing uncontrollable deformation under large external forces. The support is also more stable. To detonate, the detonation button must first be rotated to fit the positioning structure, allowing the abutment to slide downward and contact the movable and fixed trigger plates, thereby generating a detonation signal.

[0004] However, the aforementioned detonator still has certain problems in use. On the one hand, when detonating, the detonation button needs to be rotated to align the positioning pin and the positioning hole before the detonation button can be pressed to achieve detonation. However, relying solely on the two positioning points to manually align the positioning pin and the positioning hole has a large error margin. It is easy for the detonation button to be unable to be pressed due to the positioning pin and the positioning hole not being fully aligned during detonation, thus affecting the accuracy of detonation. On the other hand, the detonation button is completely exposed. If the detonator is accidentally released, the detonation button may be subjected to external impact, leading to accidental detonation.

[0005] Based on this, a rock blasting device for mining geology is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0006] The purpose of this utility model is to provide a rock blasting device for mining geology to solve the problems in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A rock blasting device for mining includes a detonator body, a detonation button on the detonator body, a protective cover on the outside of the detonation button, a back clamp on one side of the detonator body, the protective cover including a shell hinged to the detonator body, a transparent window on the shell, a buckle on the free end of the shell, and a slot on the detonator body that matches the buckle.

[0008] Based on the above technical solutions, this utility model also provides the following optional technical solutions: In one alternative: the detonator body is provided with a trigger groove, a fixed trigger head is provided in the trigger groove, an installation groove for installing a detonation button is provided above the trigger groove, a partition is provided between the installation groove and the trigger groove, and an opening is provided on the partition.

[0009] In one alternative: the mounting groove sidewall is provided with a ratchet with a semi-circular arc segment, a retraction groove is provided below the ratchet, and a baffle is provided between the ratchet and the retraction groove.

[0010] In one alternative: one end of the ratchet is provided with a starting groove, and the other end of the ratchet is provided with a positioning groove, the lower end of the positioning groove passing through a baffle and communicating with the retraction groove.

[0011] In one alternative: a reset groove is provided at one end of the retraction groove near the starting groove, and a stop is provided between the reset groove and the starting groove.

[0012] In one alternative: the detonation button includes a button that is slidably installed in a mounting groove, the lower end of the button is provided with a movable post installed in an opening, the lower end of the movable post is provided with a movable contact, and a spring is sleeved on the movable post.

[0013] In one alternative: the button has a toggle piece at its upper end, a positioning arrow at one end of the toggle piece, an indicator arrow indicating the direction of rotation on one side of the positioning arrow, a groove on the side of the button, and a pawl matching the ratchet tooth in the groove.

[0014] In one alternative: a positioning indicator light is provided on one side of the mounting slot, the positioning indicator light corresponds to the position of the positioning slot, and a trigger switch for controlling the positioning indicator light is provided in the positioning slot.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model achieves the purpose of physically isolating the button and preventing external forces from directly acting on the detonation button when it is dropped or impacted by adding a hinged protective cover with a transparent window to the outside of the detonation button, thereby completely eliminating the hidden danger of accidental detonation caused by the equipment slipping out of hand or being bumped from the side.

[0016] 2. This utility model achieves the effect of "rotating first and then pressing" in one step by precisely cooperating with the semi-circular arc segment ratchet-pawl unidirectional rotation mechanism and the end positioning groove, thus eliminating the error problem of "the positioning post and positioning hole cannot be manually aligned or pressed down" in the background technology. At the same time, by setting a trigger switch in the positioning groove and linking it with the positioning indicator light, a visual feedback of "the light turns on when the rotation is in place" is achieved, so that the operator can confirm the alignment status at a glance even in the mining environment with gloves and poor lighting, further improving the success rate of detonation and the safety of operation.

[0017] 3. This utility model achieves the function of automatically retracting the button to the starting groove after a single detonation by using an automatic reset mechanism consisting of a retraction groove, a reset groove, and a stop block, thus avoiding the risk of secondary accidental activation caused by the button remaining in the ready-to-detonate position.
