DETAILED DESCRIPTION

[0038] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.

[0039] Please refer to Figures 1-5 In the embodiments of the utility model, a coal mine waterproof safety flow guide structure includes a waterproof board 1, a water guide structure 2 and a drainage structure 3, the waterproof board 1 includes a plate body 101;The water guide structure 2 is arranged in the plate body 101, and the water guide structure 2 and the front side surface of the plate body 101 are communicated with each other;The drainage structure 3 is hinged to the rear side surface of the plate body 101, and the drainage structure 3 includes a water guide pipe 308, and the upper end of the water guide pipe 308 is communicated with the water guide structure 2.

[0040] Specifically, the plate body 101 is used as a waterproof baffle against the mine wall where water leakage occurs in the coal mine, and is supported by the drainage structure 3 to block the water leakage, while guiding and converging the water leakage by the water guide structure 2 and discharging the water leakage by the drainage structure 3, so as to avoid excessive water pressure. While blocking the water leakage, the water leakage at the blocking position can be guided and discharged automatically, so as to reduce the pressure borne by the plate body 101 and discharge the accumulated water without affecting the dry operation environment in the mine.

[0041] Embodiment one

[0042] As shown in Figure 1 , 4 and 5, in the present embodiment, the drainage structure 3 further comprises a first hinge seat 301, a hinge end 303, a support pipe 304 and a second hinge seat 306. The first hinge seat 301 is fixedly installed on the two side edges of the rear surface of the plate body 101. The hinge end 303 is hingedly connected with the first hinge seat 301. The support pipe 304 has the hinge end 303 fixedly installed on the upper and lower ends thereof. The upper end of the support pipe 304 is hingedly connected with the first hinge seat 301 through the hinge end 303. The second hinge seat 306 is hingedly connected with the lower end of the support pipe 304 through the hinge end 303. The second hinge seat 306 has a force plate 307 fixedly installed on the bottom side thereof. The force plate 307 has fastening screw holes penetratingly formed at the four corners thereof.

[0043] In the present embodiment, the plate body 101 is abutted against the surface of the mine wall. The support pipe 304 is rotated through the first hinge seat 301 and the second hinge seat 306, so as to be in an inclined state. The force plate 307 is abutted against the ground of the mine tunnel and is fastened and connected with the ground through the fastening screw holes penetratingly formed at the four corners of the force plate 307 and the bolts, so as to support the plate body 101.

[0044] As shown in Figures 4-5 , in the present embodiment, the drainage structure 3 further comprises a drainage through hole 302, a pipe groove 305, a water guide pipe 308 and a three-way pipe 309. The drainage through hole 302 is penetratingly formed in the middle of the first hinge seat 301 and is in communication with the water storage groove 201. The pipe groove 305 is formed at the opening edges of the upper and lower ends of the support pipe 304. The water guide pipe 308 is sleeved in the support pipe 304. The upper end of the water guide pipe 308 is in communication with the drainage through hole 302. The three-way pipe 309 has two ends in communication with the lower end of the water guide pipe 308.

[0045] In practice, the drainage hole 302 is opened at the upper edge of the water storage tank 201. The water will be temporarily stored inside the water storage tank 201 until the water surface passes through the drainage hole 302. The water will increase the weight of the plate 101 and increase the stability of the overall structure. At the same time, the water that passes through the drainage hole 302 will flow directly into the water guide pipe 308. After passing through the three-way pipe 309, it will be guided out through the drainage pipe connected to the middle interface of the three-way pipe 309.

[0046] Example 2

[0047] Based on Example 1, in order to supplement the specific method of collecting mine wall seepage water through water-conducting structure 2, which was not mentioned in Example 1.

[0048] like Figures 2-3 As shown, in this embodiment, the waterproof membrane 1 further includes edge strips 102, a base plate 103, and reinforcing corner brackets 104. The edge strips 102 are fixedly installed on both sides of the front surface of the membrane 101; the base plate 103 is fixedly installed on the lower edge of the front surface of the membrane 101; the reinforcing corner brackets 104 are evenly arranged and fixedly installed at the angle between the membrane 101 and the base plate 103; the water guiding structure 2 includes a water storage tank 201, a cavity groove 202, and an upwardly inclined seepage port 203. The water storage tank 201 is opened inside the membrane 101; the cavity groove 202 is evenly arranged and opened on the front surface of the membrane 101; the upper end of the upwardly inclined seepage port 203 is connected to the water storage tank 201, and the lower end of the upwardly inclined seepage port 203 is connected to the cavity groove 202.

[0049] In practice, the plate 101 abuts against the surface of the mine wall, and the bottom plate 103 inserts its sharp edge into the lower edge of the mine wall to limit the lower part of the plate 101. The drainage structure 3 then limits the upper part of the plate 101. At the same time, the side strips 102 form protrusions to strengthen the tightness between the sides of the plate 101 and the mine wall. This works in conjunction with the bottom plate 103 to seal the sides and bottom of the leaking parts of the mine wall, so that the leaking water can only flow into the water guiding structure 2 through the front surface of the plate 101. Meanwhile, the cavity groove 202 forms an inner groove on the front surface of the plate 101 to facilitate the collection of water seeping from the frame wall. When the water in the cavity groove 202 is collected to a certain height, it seeps into the water storage tank 201 through the upward inclined seepage port 203. The upward inclined seepage port 203 is designed as an inclined channel structure with a bottom inlet and a high outlet. This does not affect the seepage flow and, under the action of gravity, effectively prevents gravel and soil from entering the water storage tank 201.

[0050] It is apparent for a person skilled in the art that the present application is not limited to the details of the above-described exemplary embodiments, but that it can be implemented in other concrete forms without departing from the spirit or the essential characteristics of the present application. Therefore, the embodiments should be considered as exemplary and non-limiting, the scope of the present application being defined by the claims appended hereto rather than by the above description, and all the changes which fall within the meaning and the scope of the equivalent elements of the claims are intended to be embraced therein.
