Description

Technical Field

[0001] The utility model relates to the technical field of underground mining, in particular to a protective device for a drainage hole in an underground mine. Background Art

[0002] Civilized production management in underground mines helps mining companies comply with laws and regulations and environmental protection standards, and ensure the legality and compliance of their activities. This helps to establish a standardized mining industry and enhance the overall image and reputation of the industry. Water management in underground mines is a key element to ensure that civilized production meets standards. Effective treatment of accumulated water is not only related to the safety and environmental protection of mining work, but also an indispensable link in ensuring mining production efficiency, rational use of resources and sustainable development. Through scientific management and active management of accumulated water, mines can better comply with relevant laws and regulations, ensure the legality and compliance of their production activities, and thus achieve the goal of civilized production. This process helps to reduce the risk of accidents, improve production efficiency, and ultimately promote the entire mining industry in a safer, more environmentally friendly and efficient direction.

[0003] However, the following problems are often encountered in the existing underground mine water treatment process:

[0004] (1) Nowadays, the drainage holes of most mines are blocked by domestic garbage or buried by silt for a long time, which makes the drainage holes unable to be used normally, causing water accumulation and affecting the mine environment.

[0005] (2) In order to prevent water accumulation, mines generally use filters to filter to a certain extent. However, since the diameters of different drainage holes are also different, this will result in the need to cut and fix the filter in practice. In addition, the filter that has been used once is often unusable due to the different diameter of the next drainage hole. At this time, it needs to be cut and fixed again, which is not only time-consuming and labor-intensive but also increases costs.

[0006] (3) The strength of the filter alone is limited and cannot filter out large and heavy household garbage or stones. Utility Model Content

[0007] The main purpose of the utility model is to provide a protective device for underground mine drainage holes, so as to effectively solve the problem that the existing drainage holes mentioned in the background technology are blocked by domestic garbage for a long time.

[0008] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0009] A protective device for an underground mine drainage hole, comprising:

[0010] First steel ring;

[0011] a second steel ring, the second steel ring being stacked on top of the first steel ring;

[0012] An outer net, the outer net is composed of a plurality of metal wires bent and wound radially;

[0013] A gap knot, the gap knot is located at the contact end between the outer net and the first steel ring and the second steel ring, and one end of the gap knot is connected to the outer net;

[0014] An outer net edge, the outer net edge is arranged vertically, and the outer net edge is connected to the other end of the gap junction;

[0015] An internal network is stacked below the external network.

[0016] The first steel ring and the second steel ring have the same caliber.

[0017] The outer net is laid to cover the second steel ring.

[0018] The material of the outer net is copper wire.

[0019] The inner net is a filter net.

[0020] The gap knot is tied to the overlapping edges of the first steel ring and the second steel ring.

[0021] The outer net within the range of the second steel ring is arched.

[0022] Compared with the prior art, the beneficial effects of the utility model are:

[0023] (1) The protective device for the drain hole designed by the utility model is divided into a double-layer filter of an inner net and an outer net. The larger aperture of the outer net can effectively prevent larger debris such as domestic garbage and debris from entering the drain hole, thereby reducing the possibility of blockage, while the relatively small aperture of the inner net can effectively prevent tiny particles, mud and other fine materials from entering the drain hole, thereby keeping the drain hole unobstructed.

[0024] (2) The double-layer stacked steel rings designed in the utility model are used in conjunction with the gap knots to be scalable and can be adjusted according to the sizes of different drainage holes. That is, by pulling one of the steel rings and displacing the two steel rings, the outer net can be stretched open to expand the caliber. This design makes the protective net suitable for drainage holes of various diameters, improving its versatility and adaptability.

[0025] (3) The outer net is arched and the edge of the outer net is vertically arranged. It is inserted into the drain hole. The vertical structure and the arched top can improve the supporting strength. The outer net is made of copper and only deforms when subjected to stress, but is not easy to break.

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "set", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] like Figure 1-3As shown, a protective device for underground mine drainage holes comprises: a first steel ring 1, a second steel ring 2, an outer net 3, a gap knot 4, an outer net edge 5, and an inner net 6. The second steel ring 2 is stacked on the first steel ring 1, and the first steel ring 1 and the second steel ring 2 have the same caliber. The outer net 3 is composed of a plurality of metal wires that are bent and wound radially. The gap knot 4 is located at the contact end between the outer net 3 and the first steel ring 1 and the second steel ring 2. One end of the gap knot 4 is connected to the outer net 3. The gap reserved by the gap knot 4 is greater than the thickness of the stacking edge of the first steel ring 1 and the second steel ring 2. The gap knot 4 is reserved to provide a space for the first steel ring 1 and the second steel ring 2 to move. The larger the reserved space of the gap knot 4, the wider the space for the first steel ring 1 and the second steel ring 2 to move. The outer net edge 5 is arranged vertically, and the vertical arrangement is convenient for inserting the outer net edge 5 into a drainage hole with a smaller caliber for use. The outer net edge 5 is connected to the other end of the gap knot 4, and the inner net 6 is stacked below the outer net 3.

[0034] In this embodiment, Figure 2-3 As shown, the outer net 3 is the outer layer of the protective net, and its aperture is about 2 cm. This larger aperture can effectively prevent larger objects such as domestic garbage, debris, etc. from entering the drainage hole, thereby reducing the possibility of blockage. The aperture of the inner net 6 is about 2 mm. This relatively small aperture can effectively prevent fine particles, silt and other fine materials from entering the drainage hole, keeping the drainage hole unobstructed. The edge 5 of the outer net adopts a three-dimensional design to make it more prominent in the drainage hole so that the operator can clearly identify it. This helps to prevent the protective net from being buried by silt or slag and improve the protective effect. The material of the outer net 3 is copper wire, which is a metal with good ductility. The use of copper wire to weave the outer net 3 can also prevent plastic deformation and not easy to break when encountering large stones. Once the caliber needs to be expanded, one of the steel rings can be pulled to dislocate the two steel rings to open the outer net 3. The use of copper wire can also reduce the pulling force required for expanding the caliber.

[0035] In the above embodiments, the materials required for making the present invention are all conventional materials. This arrangement makes it easier for on-site personnel to make the products manually without carrying finished products, thereby improving versatility.

[0036] It should be noted that the protective device for underground mine drainage holes designed by the utility model can be directly inserted into the drainage holes with smaller apertures after the bottom of the outer net edge 5 is squeezed and constrained and adjusted for use. For drainage holes with larger apertures, it is necessary to manually pull one of the first steel rings 1 or the second steel ring 2 to cause the two first steel rings 1 and the second steel ring 2 to be misaligned. The two steel rings move in a misaligned manner in the reserved space of the gap 4. The support range of the first steel ring 1 and the second steel ring 2 is expanded to open the outer net 3 to accommodate the use of drainage holes with larger apertures. At this point, the disassembly process is completed.

[0037] Although the embodiments of the present invention have been shown and described, it will be apparent to those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
