[0022] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0025] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0026] Example 1

[0027] Reference Figure 1-5 , an anti-corrosion base for an overhead coal transportation gallery is provided, comprising a gallery base 100; a protective net 101, which is arranged on both sides of the gallery base 100; and a reinforcing rib 102, which is arranged above the protective net 101;

[0028] Stainless steel protective nets 101 are set on both sides and fixed on the frame. The safety net can effectively prevent coal and personnel from accidentally scattering and ensure the safety of the area below the corridor; the reinforcing ribs 102 are welded to the base and the protective net 101 frame to form a stable support system. Coal particles fall to the top or both sides of the corridor base 100, and the particles falling below will directly contact the fireproof rubber layer without the risk of falling below.

[0029] Specifically, the corridor base 100 includes a grating plate 100a and a fireproof rubber pad 100b arranged above the grating plate 100a. The grating plate 100a is designed to have good load-bearing capacity and ventilation permeability, which can effectively reduce the accumulation of coal dust. These rubber pads can not only drain the water in the flushing operation of the coal transportation system, but also protect the base from wear.

[0030] Furthermore, the grating plate 100a is cut and welded from Q235B steel, which has high strength and load-bearing capacity: Q235B is a low-carbon steel, which has high strength and load-bearing capacity after welding and can withstand greater pressure and weight; Q235B steel has good welding performance, and generally does not require special preheating and post-weld heat treatment during welding, nor does it require complex welding equipment; Q235B steel can still maintain good toughness in low temperature environments and is suitable for construction in various complex environments; Q235B steel has good corrosion resistance, can resist the erosion of various corrosive media, and extend the service life of the pipeline.

[0031] Furthermore, the protective net 101 is made of stainless steel.

[0032] Example 2

[0033] Reference Figure 1-5 This embodiment is different from the first embodiment in that: the grid plate 100a is 50mm thick, of which the grid is 10mm thick, and an inner hole 100a-1 is opened inside the grid plate 100a, and the inner hole 100a-1 is 30mmX30mm square. During the flushing work of the coal conveying corridor, the flushing water will be directly discharged through the grid plate 100a and the rubber plate, and there will be no local water accumulation, thereby avoiding corrosion caused by coal and water accumulation.

[0034] Specifically, the thickness of the fireproof rubber pad 100b is set to 5mm, and a circular hole 100b-1 is set on the fireproof rubber pad 100b. The diameter of the circular hole 100b-1 is 3mm. There are multiple circular holes 100b-1, and the interval between the multiple circular holes 100b-1 is 5mm. When people walk in the coal transportation corridor, the rubber pad has a reduced contact area with the soles of the people due to the presence of the circular holes 100b-1, and the friction coefficient is larger, making it less likely to slip. The protective nets 101 on both sides can effectively protect people from falling accidents.

[0035] Furthermore, the mesh size of the protective net 101 is set to 30×30 mm, which is smaller than 30X30 mm to ensure effective interception.

[0036] Furthermore, reinforcing ribs 102 are arranged along the length of the corridor. The reinforcing ribs 102 are made of stainless steel. Multiple reinforcing ribs 102 are arranged every 4 meters. Stainless steel reinforcing ribs 102 are installed every 4 meters along the length of the corridor to enhance the overall stability of the structure.

[0037] The rest of the structure is the same as that of Example 1.

[0038] Example 3

[0039] Reference Figure 1-5, this embodiment is different from the above embodiment in that: the fireproof rubber pad 100b is made of EPDM, which has excellent resistance to a variety of chemicals, including acids, alkalis, detergents, animal and vegetable oils, alcohols, ketones, etc. In addition, it also has outstanding resistance to hot water and water vapor, as well as good oil resistance; EPDM has excellent electrical insulation and corona resistance, and is suitable for occasions requiring good insulation performance; EPDM has a wide range of operating temperature, and can work normally in the temperature range of -40℃ to +150℃, and can even withstand higher temperatures in a short time. This makes it widely used in high temperature environments.

[0040] Specifically, the grating plate 100a is galvanized. The benefits of galvanization include preventing metal corrosion, extending service life, improving aesthetics and reducing maintenance costs. After galvanization, it is installed on a preset supporting steel frame foundation to ensure the stability and durability of the entire structure.

[0041] The rest of the structure is the same as that of Example 2.
