However, the shock waves and flying objects generated by blasting operations pose a serious threat to the surrounding environment, equipment, and personnel. Effective protection measures must be taken to ensure the safety of operations, and thus a protection device for blasting operations is needed to achieve this.

[0003] Traditional protection devices often adopt fixed structures, such as frames welded or bolted together with strong metal materials such as steel beams and steel columns. This structure lacks flexibility. Once built, the angle and position are difficult to change and cannot be flexibly adjusted according to the blasting scale and expected impact range, resulting in limited protection effect and being prone to damage or displacement under strong impacts, further increasing the safety risk. Therefore, a protection device for blasting operations in ore mining is proposed to solve the above problems. Summary of the Utility Model

[0004] In order to make up for the above deficiencies, the utility model provides a protection device for blasting operations in ore mining, aiming to improve the problem that traditional protection devices often adopt fixed structures, which lack flexibility. Once built, the angle and position are difficult to change and cannot be flexibly adjusted according to the blasting scale and expected impact range.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: A protection device for blasting operations in ore mining includes a first protection plate, a second protection plate, a first baffle, and a second baffle. Two guide rods are fixedly connected to the inner side of the second protection plate. A plurality of slots are formed on the outer side of one of the guide rods. A moving plate is slidably connected to the outer side of the guide rod. Two connecting rods are rotatably connected to the top of the moving plate. An installation shell is fixedly connected to the outer side of the moving plate. A first spring is fixedly connected to the inner wall of the installation shell. One end of the first spring is fixedly connected to a plug post. A push plate is fixedly connected to the outer side of the plug post. An adapter plate is fixedly connected to the end of the guide rod away from the second protection plate. Protection components are arranged on the outer sides of the first protection plate and the second protection plate, and the protection components are used for protecting the first protection plate and the second protection plate.

[0006] As a further description of the above technical solution:

[0007] The protection component includes a plurality of mounting cylinders and two protection plates. The bottoms of the plurality of mounting cylinders are respectively fixedly connected to the outer sides of the corresponding protection plate one and protection plate two. The bottom of one of the protection plates is fixedly connected to the outer side of protection plate one, and the bottom of the other protection plate is fixedly connected to the outer side of protection plate two.

[0008] As a further description of the above technical solution:

[0009] A second spring is fixedly connected to the inner bottom wall of the mounting cylinder. The other end of the second spring is fixedly connected to a connecting plate, and the top of the connecting plate is fixedly connected to a connecting column.

[0010] As a further description of the above technical solution:

[0011] The tops of the plurality of connecting columns are respectively fixedly connected to the outer sides of the corresponding baffle one and baffle two.

[0012] As a further description of the above technical solution:

[0013] The top of the connecting rod is rotatably connected to the bottom of protection plate one.

[0016] As a further description of the above technical solution:

[0017] The bottoms of both protection plate two and the connecting plate are fixedly connected with bases.

[0018] As a further description of the above technical solution:

[0019] A plurality of fixing holes are formed inside the base.

[0020] The utility model has the following beneficial effects:

[0021] 1. In the utility model, according to the blasting scale and the expected impact range, the angle between protection plate one and protection plate two is adjusted. Then, by pushing the push plate, the plug post is driven to move and compress the first spring. During this process, the plug post will gradually disengage from the corresponding slot on the guide rod. When it is completely disengaged from the slot, by pushing the moving plate, the connecting rod drives protection plate one to rotate, thereby adjusting the angle between protection plate one and protection plate two. Then, the push plate is released, and under the elastic action of the first spring, the plug post is inserted into the corresponding slot, thus fixing the moving plate to prevent accidental displacement during use. By adjusting the angle, according to actual needs, the protection device can be made to fit more closely to the impact direction of the blasting point, providing more effective protection.

[0022] 2. In the present utility model, when blasting occurs, the shock wave and flying debris first come into contact with baffle one and baffle two, and then squeeze the corresponding connecting columns. As a result, the connecting columns drive the connecting plate to squeeze spring two. When spring two is squeezed, it converts the impact energy into elastic potential energy and stores it. When the impact weakens or disappears, spring two gradually returns to its original state and releases energy. The rebounding force of spring two causes the connecting plate and the connecting columns to return to their initial positions, thus achieving the effects of buffering and dispersing the impact, and realizing the ability to more effectively improve the protection performance of the safe area.

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] Refer to Figure 1 , Figure 3 And Figure 4, an embodiment provided by the present utility model: a protection device for ore mining blasting operations, including a first protection plate 1, a second protection plate 2, a first baffle 13 and a second baffle 19. Two guide rods 3 are fixedly connected to the inner side of the second protection plate 2. A plurality of slots 6 are provided on the outer side of one of the guide rods 3. A moving plate 4 is slidably connected to the outer side of the guide rod 3. Two connecting rods 5 are rotatably connected to the top of the moving plate 4. The top of the connecting rod 5 is rotatably connected to the bottom of the first protection plate 1. An installation shell 7 is fixedly connected to the outer side of the moving plate 4. A first spring 8 is fixedly connected to the inner wall of the installation shell 7. One end of the first spring 8 is fixedly connected to a plug post 9. A push plate 10 is fixedly connected to the outer side of the plug post 9. The plug post 9 is in plug-in fit with the corresponding slot 6. A connecting plate 15 is fixedly connected to the end of the guide rod 3 away from the second protection plate 2. Bases 16 are fixedly connected to the bottoms of the second protection plate 2 and the connecting plate 15. A plurality of fixing holes are provided inside the bases 16.

[0032] Specifically, before the blasting operation, the first step is to ensure that the protection device is firmly installed in the working area. Through the plurality of fixing holes pre-opened on the base 16, the staff can use special fixing parts (such as anchor bolts, expansion bolts, etc.) to firmly drive or fix the base 16 on the solid ground. Next, according to the scale of the blasting operation and the expected impact range, it is necessary to adjust the angle between the first protection plate 1 and the second protection plate 2 to more precisely adapt to and block the shock wave and flying objects generated by the blasting. By pushing the push plate 10, the plug post 9 will also move accordingly. During the movement, the plug post 9 will gradually compress the first spring 8 and at the same time disengage from the originally plugged slot 6 on the guide rod 3, pushing the moving plate 4. The moving plate 4 is rotatably connected to the first protection plate 1 through the connecting rod 5. Therefore, the movement of the moving plate 4 will drive the first protection plate 1 to rotate around the connection point. As the first protection plate 1 rotates, the angle between it and the second protection plate 2 also changes accordingly. Then release the push plate 10, and under the elastic action of the first spring 8, the plug post 9 is inserted into the corresponding slot 6 to fix the moving plate 4 and prevent accidental displacement during use, thus realizing the adjustment of the angle of the protection plate. Through the adjustment of the angle, according to actual needs, the protection device can be made to fit more closely to the impact direction of the blasting point and provide more effective protection. The connecting plate 15 provides stability for the guide rod 3.

[0033] Refer to Figure 1 , Figure 2 and Figure 5, protective components are provided on the outer sides of both the first protective plate 1 and the second protective plate 2. The protective components are used to protect the first protective plate 1 and the second protective plate 2. The protective components include a plurality of mounting cylinders 11 and two protective plates 14. The bottoms of the plurality of mounting cylinders 11 are respectively fixedly connected to the outer sides of the corresponding first protective plate 1 and the second protective plate 2. The bottom of one of the protective plates 14 is fixedly connected to the outer side of the first protective plate 1, and the bottom of the other protective plate 14 is fixedly connected to the outer side of the second protective plate 2. A second spring 17 is fixedly connected to the inner bottom wall of the mounting cylinder 11. The other end of the second spring 17 is fixedly connected to a connecting plate 18. A connecting column 12 is fixedly connected to the top of the connecting plate 18. The tops of the plurality of connecting columns 12 are respectively fixedly connected to the outer sides of the corresponding first baffle 13 and the second baffle 19.

[0034] Specifically, when a blast occurs, the shock wave and flying debris will first come into contact with the outer structure of the protective device, namely the first baffle 13 and the second baffle 19. Then, the shock wave and flying debris will continue to squeeze the connecting columns 12 behind the baffles. The force on the connecting columns 12 will be transmitted to the connecting plate 18, thereby compressing the second spring 17, effectively slowing down the speed and force of the impact. As the blast impact weakens or disappears, the second spring 17 begins to gradually return to its original state and release the stored elastic potential energy. The rebounding force of the second spring 17 causes the connecting plate 18 and the connecting columns 12 to return to their initial positions, preparing for the next possible impact, achieving more effective protection performance in the safety area. The protective plate 14 provides protection for the mounting cylinder 11 to prevent the shock wave and flying debris from directly contacting the mounting cylinder 11.

[0035] Working principle: Before the blasting operation, the fixing piece is driven into the ground through the fixing hole on the base 16 to fix the device. Then, according to the blasting scale and the expected impact range, the angle between the first protective plate 1 and the second protective plate 2 is adjusted. Then, by pushing the push plate 10, the plug post 9 is driven to move and compress the first spring 8. During this process, the plug post 9 will gradually disengage from the corresponding slot 6 on the guide rod 3. After completely disengaging from the slot 6, by pushing the moving plate 4, the connecting rod 5 drives the first protective plate 1 to rotate, thereby adjusting the angle between the first protective plate 1 and the second protective plate 2. Then, the push plate 10 is released, and the plug post 9 is inserted into the corresponding slot 6 under the elastic action of the first spring 8, thereby fixing the moving plate 4 to prevent accidental displacement during use. By adjusting the angle, according to actual needs, the protective device can be made to fit the impact direction of the blasting point more closely, providing more effective protection.

[0036] When a blast occurs, the shock wave and flying debris first come into contact with baffle one 13 and baffle two 19, and then squeeze the corresponding connecting columns 12. As a result, the connecting columns 12 drive the connecting plate 18 to squeeze spring two 17. When spring two 17 is squeezed, it converts the impact energy into elastic potential energy and stores it. When the impact weakens or disappears, spring two 17 gradually returns to its original state and releases energy. The rebounding force of spring two 17 causes the connecting plate 18 and the connecting columns 12 to return to their initial positions, thus achieving the effect of buffering and dispersing the impact and enabling more effective improvement of the protection performance of the safe area.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
