Description

Technical Field

[0001] This invention relates to the field of mining monitoring, and more particularly to a safety monitoring device for mining areas. Background Technology

[0002] In mining areas, monitoring equipment is used for safety surveillance. Existing monitoring equipment is typically equipped with dedicated mounting rods, which are fixed to the mine wall using bolts during installation. However, in actual mining operations, mine walls are often uneven and undulating, lacking a sufficiently flat mounting surface. This unevenness makes it difficult for bolts to fit and tighten completely, resulting in an unstable and reliable mounting rod and poor overall equipment stability. Furthermore, this type of equipment with mounting rods has very limited adaptability, only suitable for smooth wall surfaces. It fails to meet the actual installation requirements when encountering complex and varied underground mine structures. In addition, during transportation, equipment with mounting rods requires significant space, increasing overall transportation costs and hindering the efficient transfer of multiple sets of equipment.

[0003] To address the aforementioned issues, this application proposes a safety monitoring device for mining areas, aiming to improve upon the technical shortcomings of existing technologies, such as poor installation stability, insufficient adaptability, and high transportation costs. Summary of the Invention

[0004] To overcome the limitations of traditional monitoring equipment with mounting poles, which are only suitable for flat wall surfaces and fail to meet actual installation requirements in complex and varied underground mine structures, this invention provides a safety monitoring device for mining areas.

[0005] The technical implementation of the present invention is as follows: a safety monitoring device for a mining area, comprising a mounting base and a cover; the cover is mounted on the mounting base; a monitoring lens is provided on the mounting base, and the cover surrounds the monitoring lens; a cover plate with an arc-shaped structure is installed on the mounting base; a pair of receiving grooves are provided on the mounting base; a connecting shaft is mounted on the mounting base; a pair of connecting strips are rotatably mounted on the connecting shaft; a torsion spring is connected between each connecting strip and the mounting base; a connecting piece is fixedly mounted on each connecting strip, the connecting piece is located in the receiving groove, and the connecting piece is an elastic metal sheet.

[0006] More preferably, each storage groove has multiple telescopic spring rods installed on its upper and lower sides; each pair of telescopic spring rods on the corresponding side has an arc plate fixedly installed on its telescopic part, and the arc plate is slidably connected to the mounting base.

[0007] A more preferred option is to chamfer the outer surface of the curved plate.

[0008] More preferably, each connecting piece is equipped with a pair of arc-shaped ribs made of elastic material, and the rebound force of the arc-shaped ribs is greater than the rebound force of the connecting piece.

[0009] More preferably, the mounting base is fixedly mounted with multiple arc-shaped elastic rods that are fixedly mounted with the cover plate; the mounting base is fixedly mounted with a ring plate, and each arc-shaped elastic rod is fixedly mounted with a silicone buffer block, and the silicone buffer block is connected to the ring plate.

[0010] More preferably, the arc-shaped elastic rod is composed of a rubber buffer rod and a metal support rod; the silicone buffer block is connected to the metal support rod; a rubber buffer rod is fixedly installed at each of the upper and lower ends of the metal support rod, and the rubber buffer rod at the upper end is connected to the cover plate, while the rubber buffer rod at the lower end is connected to the mounting base.

[0011] More preferably, a cavity is provided inside the mounting base; a pair of electric drive push rods are fixedly mounted on the mounting base, and the push rod ends of the electric drive push rods are connected to the cover.

[0012] More preferably, the mounting base has an air inlet with a filter; a temperature sensor is installed inside the mounting base; the mounting base has an airflow channel communicating with the air inlet; a fan is installed inside the airflow channel; an annular duct communicating with the airflow channel is fixedly installed on the mounting base; and multiple air blowing pipes are installed on the annular duct.

[0013] More preferably, the blower duct is positioned to face the housing.

[0014] More preferably, the air intake is located below the ring plate.

[0015] Compared with existing technologies, this invention has the following advantages: During installation, the operator first presses the outer surfaces of a pair of connecting plates tightly against the mine wall, and then uses the bolt holes on the connecting plates to lock them with bolts, thereby completing the fixation of the equipment. In this state, the connecting plates bend and deform towards the wall under the continuous action of the torsion spring, thereby applying preload stress to the locking bolts and enhancing the reliability of the fixation. At the same time, since the connecting plates are made of elastic metal sheets, they can adapt well to the uneven shape of the mine wall, thus improving the overall installation stability of the equipment.

[0016] When monitoring equipment needs to be installed on an existing pole structure, a pair of connecting plates can be wrapped around the outside of the vertical pole and then tightened with bolts to secure the equipment to the vertical pole. Alternatively, a pair of connecting plates can be bent into a C-shape to surround the horizontal pole and then fastened with bolts to fix the equipment to the horizontal pole. These two methods effectively expand the applicability of the equipment to different installation scenarios.

[0017] During operation, the metal support rods form an impact-resistant layer to protect the mounting base, while the rubber buffer rods absorb and cushion the impact force on the metal support rods. Simultaneously, the silicone buffer block in the middle of the flexible support rods further buffers the impact force, thus comprehensively improving the stability of the monitoring equipment during operation. During storage or transportation, placing the side with the flexible support rods facing down allows the flexible support rods to effectively buffer transportation vibrations, thereby improving the safety of the equipment during transport.

Detailed Implementation

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1: A safety monitoring device for mining areas, referring to... Figures 1-8 As shown, it includes a mounting base 1 and a cover 2; the cover 2 is fixedly connected to the lower side of the mounting base 1; a monitoring lens is installed inside the mounting base 1, and the monitoring lens is located within the space enclosed by the cover 2.

[0022] The device further includes a cover plate 3, a connecting piece 4, a connecting strip 41, and a torsion spring 42. The cover plate 3, which has an arc-shaped structure, is fixed to the upper side of the mounting base 1 to guide falling gravel to slide outwards. A pair of receiving grooves 1001 are provided on the mounting base 1. A connecting shaft 1002 is also fixed to the mounting base 1, on which a pair of vertically distributed connecting strips 41 are rotatably mounted. Each connecting strip 41 is fixed with a torsion spring 42, and the other end of the torsion spring 42 is fixedly connected to the mounting base 1. Each connecting strip 41 is also fixed with a connecting piece 4, which has multiple bolt holes. The connecting piece 4 is made of an elastic metal sheet and is initially housed inside the receiving groove 1001.

[0023] In addition, the device also includes an arc plate 5 and a telescopic spring rod 51; a pair of telescopic spring rods 51 are fixed on the upper and lower sides of each storage groove 1001; the telescopic ends of the pair of telescopic spring rods 51 on each side are fixedly connected to an arc plate 5, and the arc plate 5 and the mounting base 1 form a sliding fit; the outer side of the arc plate 5 is chamfered so that the connecting piece 4 can be quickly pressed and retracted into the storage groove 1001 by hand.

[0024] The device is also provided with arc-shaped ribs 6; each connecting piece 4 has a pair of arc-shaped ribs 6 fixed on its outer side. The arc-shaped ribs 6 are made of elastic material and their own rebound force is greater than that of the connecting piece 4. When the connecting piece 4 is removed from the storage groove 1001, the upper and lower ends of the connecting piece 4 will bend and deform outward under the rebound force of the arc-shaped ribs 6.

[0025] Furthermore, the device also includes an arc-shaped elastic rod 101, a silicone buffer block 102, and a ring plate 103; multiple arc-shaped elastic rods 101 are fixed on the mounting base 1, and the upper ends of these arc-shaped elastic rods 101 are fixedly connected to the cover plate 3; a ring plate 103 is also fixed on the mounting base 1, and the ring plate 103 is made of rubber; a silicone buffer block 102 is fixed on each arc-shaped elastic rod 101, and the silicone buffer block 102 is also fixedly connected to the ring plate 103.

[0026] Specifically, the arc-shaped elastic rod 101 is composed of a rubber buffer rod 10101 and a metal support rod 10102; the silicone buffer block 102 is fixedly connected to the metal support rod 10102; a rubber buffer rod 10101 is fixed at each of the upper and lower ends of the metal support rod 10102, wherein the rubber buffer rod 10101 at the upper end is fixedly connected to the cover plate 3, and the rubber buffer rod 10101 at the lower end is fixedly connected to the mounting base 1; when gravel falls and hits the arc-shaped elastic rod 101, the metal support rod 10102 can protect the mounting base 1, and at the same time, the rubber buffer rod 10101 can absorb and buffer the impact force received by the metal support rod 10102.

[0027] The device also includes an electric drive push rod 104; the mounting base 1 has an internal cavity; a pair of electric drive push rods 104 are fixed on the mounting base 1, and the push rod end of the electric drive push rod 104 is fixedly connected to the housing 2; when the device falls, the electric drive push rod 104 can drive the housing 2 to move upward and store it in the cavity of the mounting base 1, thereby protecting the monitoring lens inside the housing 2.

[0028] In practical applications, the working process of this embodiment is as follows: Existing monitoring equipment generally comes with mounting rods, which need to be bolted to the mine wall. However, mine walls are often uneven, making it difficult to achieve stable anchoring of the mounting rods, resulting in poor overall fixation; moreover, these mounting rods can only adapt to flat surfaces, lacking versatility. To address this deficiency, at the beginning of installation, the operator manually moves the arc plates 5 on the upper and lower sides of the receiving groove 1001 in opposite directions, thereby releasing the constraint on the connecting piece 4. At this time, the telescopic spring rod 51 is compressed. Then, the pair of connecting pieces 4 inside the receiving groove 1001 are removed, completely detaching them from the receiving groove 1001. Figure 1 For reference, a pair of connecting plates 4, driven by torsion spring 42, rotate and unfold to the right around connecting shaft 1002, presenting as follows: Figure 3 The state is shown in the image. Subsequently, the operator presses the outer surfaces of the pair of connecting plates 4 tightly against the mine wall and uses the pre-drilled bolt holes on the connecting plates 4 to tighten them with bolts, thus completing the installation. During this process, the connecting plates 4 are continuously bent and deformed towards the wall by the torsion spring 42, thereby applying pre-tightening stress to the locking bolts and effectively enhancing the reliability of the fixation.

[0029] Additionally, when monitoring equipment needs to be installed on an existing pole-like structure, such as Figure 5 As shown, a pair of connecting pieces 4 can be wrapped around the outside of the vertical rod and then tightened with bolts to achieve fixation on the vertical rod; as shown Figure 6 As shown, a pair of connecting pieces 4 can also be arranged in a C-shape to surround the transverse rod and then fixed with bolts, thus adapting to the installation requirements of the transverse rod. The above methods greatly enrich the installation application scenarios of the equipment.

[0030] Each connecting piece 4 has a pair of elastic arc-shaped ribs 6 fixedly installed on its outer surface, and the rebound force of the arc-shaped ribs 6 is greater than that of the connecting piece 4 itself. Once the connecting piece 4 is removed from the storage groove 1001, the arc-shaped ribs 6, with their strong rebound force, force the upper and lower ends of the connecting piece 4 to bend and deform outwards, causing the connecting piece 4 to bend and conform to the mine wall as a whole, thereby further improving the fit between the connecting piece 4 and the irregular wall surface and enhancing the installation stability.

[0031] From a transportation perspective, traditional monitoring equipment with mounting poles occupies a large space, leading to increased transportation costs. When disassembling and storing this device, the operator first removes the bolts on the connecting piece 4, then manually bends the connecting piece 4 back to its original shape. Next, the two arc plates 5 are pushed back to their original positions, pressing the connecting piece 4 into the storage groove 1001. Finally, the arc plates 5 are released, allowing them to re-secure the connecting piece 4 within the storage groove 1001. Compared to traditional equipment that requires additional space for the mounting pole, this device reduces its overall size, facilitating storage and transportation.

[0032] Once the equipment is fixed to the mine wall and put into monitoring operation, considering that mining vibrations often cause falling rocks, the upper side of the mounting base 1 of this device is equipped with an arc-shaped cover plate 3, which can effectively block and guide the falling rocks, preventing them from directly impacting the core of the equipment and providing protection. Simultaneously, the mounting base 1 is also equipped with a ring plate 103, which can intercept falling rocks and deflect them away from the casing 2, further strengthening the protection of the casing 2 and its internal monitoring camera. If a rock strikes the arc-shaped elastic rod 101 on the mounting base 1, the metal support rod 10102 forms an anti-collision layer to protect the mounting base 1, while the rubber buffer rod 10101 absorbs and buffers the impact on the metal support rod 10102; the silicone buffer block 102 in the middle of the arc-shaped elastic rod 101 also participates in absorbing impact energy, thereby improving the equipment's resistance to disturbances during operation.

[0033] Furthermore, if the equipment faces the risk of detachment due to vibration, loosening, or bolt corrosion during operation, the system will immediately activate the electric drive push rod 104 when the monitoring lens inside the housing 2 detects abnormal changes in the image. This will drive the housing 2 upwards, retracting it into the inner cavity of the mounting base 1, thus providing active protection for the monitoring lens. If the equipment ultimately falls to the ground, the arc-shaped elastic rod 101 can effectively absorb and buffer the impact force, significantly reducing the degree of damage. During storage or transportation, the side containing the arc-shaped elastic rod 101 can be placed downwards to buffer vibrations during transport, further enhancing the safety of equipment transportation.

[0034] Example 2: Based on Example 1, referring to... Figure 2 , Figure 7 and Figure 8As shown, it also includes a fan 201, an annular duct 202, and a blower pipe 203; wherein, an air inlet 1004 is provided on the mounting base 1, and a filter screen is installed at the air inlet 1004; a temperature sensor is provided inside the mounting base 1; in addition, an airflow channel 1003 is provided inside the mounting base 1, and the fan 201 is installed in the airflow channel 1003; an annular duct 202 is fixedly connected to the mounting base 1, and the annular duct 202 is connected to the airflow channel 1003 and the air inlet 1004 respectively, and multiple blower pipes 203 are connected to the annular duct 202.

[0035] The outlets of each blower pipe 203 are arranged facing the cover 2, and are used to blow airflow onto the surface of the cover 2, thereby improving the cleaning effect on the surface of the cover 2. When the cover 2 is subsequently stored in the cavity of the mounting base 1, the airflow formed by the blower pipe 203 can form an air curtain, effectively preventing external dust from entering the cavity of the mounting base 1.

[0036] In addition, the air inlet 1004 is located below the ring plate 103; with the shielding effect of the ring plate 103, the dust raised by falling gravel above can be effectively blocked, preventing dust and small gravel from entering the air inlet 1004, thereby ensuring the cleanliness of the incoming air.

[0037] Based on the above embodiment 1, given that the ambient temperature inside the mine is generally high and the equipment accumulates heat during continuous operation, an effective heat dissipation mechanism is required. The specific operation is as follows: During real-time monitoring, once the temperature sensor inside the mounting base 1 detects that the temperature inside the equipment cavity exceeds a preset safety threshold, the system automatically triggers the fan 201 to start. The suction force generated by the fan 201 drives outside air through a filter to remove dust and impurities, and then into the airflow channel 1003 through the air inlet 1004, thereby achieving active cooling of the internal area of ​​the equipment and preventing component aging, performance degradation, or even damage due to continuous heat accumulation. Simultaneously, in this heat dissipation airflow path, air flows sequentially through the airflow channel 1003 and the annular duct 202, and finally is sprayed from the blower duct 203 onto the outer surface of the housing 2. This airflow effectively blows away dust particles attached to the surface of the housing 2, ensuring that the monitoring images of the surrounding environment captured by the monitoring lens inside the housing 2 remain clear and unobstructed.
