[0002] A Chinese patent with publication number CN220955710U discloses a mine tunnel roof seepage drainage device, which receives and guides the seepage water dripping in the tunnel through a roof frame. The tunnel usually has a long straight-line distance and a relatively closed space structure. These characteristics make it easy for sound to be reflected back by the wall during propagation, forming an echo, which in turn causes the noise generated by the seepage water dripping on the roof frame to increase, resulting in a worse working environment in the tunnel. At the same time, the seepage water dripping on the roof frame is prone to splashing and scouring the tunnel wall, affecting the tunnel construction. In addition, since the walls are not specially trimmed at the beginning of the tunnel construction, the surface is uneven, and the roof frame must be smaller than the size of the tunnel, while the seepage position in the tunnel is random, and there may be a situation where some of the seepage water dripping positions still have a large height difference with the roof frame, resulting in splashing of the seepage water dripping on the roof frame.

DETAILED DESCRIPTION

[0028] First of all, it should be pointed out that in the different described embodiments, the same parts are provided with the same reference numerals or the same component names, wherein the disclosure contained in the entire description can be transferred to the same parts with the same reference numerals or the same component names. Selected positional descriptions in the description, such as top, bottom, lateral, etc., also refer to the directly described and shown figures and are transferred to the new positions in the case of a change in position.

[0029] Embodiment 1

[0030] A drainage device for mine construction, according to Figure 1-Figure 7 As shown, it includes an arch frame 1, a roller 2 and a guide plate 3; two rollers 2 are bolted to both sides of the arch frame 1; a guide plate 3 is welded to the left and right parts of the convex curved surface of the arch frame 1;

[0031] It also includes a water-absorbing sponge 101, an arched airbag 102, an air guide tube 103, an air pump 104 and a collecting component; the arched frame 1 is connected to the arched airbag 102, which is set as a rubber airbag; the water-absorbing sponge 101 is connected to the arched airbag 102; the left and right parts of the concave curved surface of the arched frame 1 are each connected to a collecting component; a plurality of through-type channels are opened on the arched frame 1, the guide plate 3 is aligned with the lower edge of the through-type channel, the end of the arched airbag 102 is located above the through-type channel, and the inlet of the collecting component is connected to the through-type channel; each collecting component is connected to an air pump 104; each air delivery port of the air pump 104 is connected to an air guide tube 103; both air guide tubes 103 are connected to the arched airbag 102.

[0032] The collection assembly includes a collection box 201 and a drain valve 204 ; the collection box 201 is bolted to the concave surface of the arch frame 1 ; the inlet of the collection box 201 is connected to the through-type channel of the arch frame 1 ; and the collection box 201 is connected to the drain valve 204 .

[0033] It also includes an impurity box 202 and a filter screen 203; each collection box 201 is plugged with an impurity box 202; each impurity box 202 is provided with a rectangular groove facing the corresponding drain valve 204; each rectangular groove is provided with a filter screen 203.

[0034] It also includes a fixing plate 4; a fixing plate 4 is welded to the left and right parts of the arch frame 1; and each fixing plate 4 is provided with a bolt hole.

[0035] During operation, the operator pushes the arch frame 1 to make the roller 2 roll on the ground, so that the arch frame 1 moves to the working area, and then fixes the arch frame 1 in the tunnel through bolts and the fixing plate 4. When water drips from the tunnel, the dripping water is absorbed by the absorbent sponge 101, thereby avoiding the problem of noise caused by water dripping on the top frame in the existing device, and greatly reducing the probability of splashing after water dripping from a high place, thereby avoiding the erosion of the tunnel wall by a large amount of splashing after water dripping, thereby affecting the tunnel construction.

[0036] Since the walls of the tunnel were not specially trimmed at the beginning of the tunnel construction process and were in an uneven state, the initial size of the water-absorbing sponge 101 was set smaller than the tunnel size to facilitate its movement in the tunnel. Then, during operation, the air pump 104 was started to inflate the arched airbag 102 through the air guide tube 103 to expand the arched airbag 102. The expansion of the arched airbag 102 simultaneously drives the water-absorbing sponge 101 to deform and expand, so that the water-absorbing sponge 101 is close to the tunnel wall, reducing the distance between the water-absorbing sponge 101 and the tunnel wall, thereby further reducing the possibility of splashing after water seepage drips from a high place. As the amount of water absorbed by the water-absorbing sponge 101 increases, part of the water in the water-absorbing sponge 101 flows downward onto the guide plate 3 due to gravity, and the water is guided by the guide plate 3, passes between the guide plate 3 and the end of the water-absorbing sponge 101, and then passes through the through-type channel on the surface of the arch frame 1 to enter the collection box 201 for collection. At the same time, the water-absorbing sponge 101 is used to receive and buffer impurities such as broken soil and gravel that fall from the tunnel wall, and the guide plate 3 is also used to guide impurities such as broken soil and gravel into the collection box 201, so that the water-absorbing sponge 101 has a certain protective effect while absorbing the seepage effect.

[0037] After the work is completed, the drain valve 204 is opened, and the water collected in the collection box 201 passes through the filter net 203 and is discharged through the drain valve 204 for unified collection and treatment, while impurities such as broken soil and gravel are intercepted by the filter net 203 and remain in the impurity box 202. After all the water collected in the collection box 201 is discharged, the impurity box 202 is taken out of the collection box 201 to treat the impurities such as broken soil and gravel.

[0038] Second embodiment

[0039] On the basis of the first embodiment, according to Figure 1-Figure 5 and Figure 8-Figure 10 As shown,

[0040] It also includes an electric rope reel 301, a pull rope 302, an elastic member 303 and a scraper 304; an electric rope reel 301 is installed on the collecting box 201 on one side of the arch frame 1; the pull rope 302 is wound around the rotating part of the electric rope reel 301; two symmetrically arranged arch grooves are opened on the arch frame 1, and an elastic member 303 slides in each arch groove; the telescopic ends of the two elastic members 303 are commonly connected to the scraper 304; the free ends of the pull rope 302 are respectively connected to the fixed ends of the two elastic members 303.

[0041] It also includes a guide wheel 305; a guide wheel 305 is rotatably connected to the outside of the fixed ends of the two elastic members 303; the two guide wheels 305 are both located in the arched groove on the arch frame 1, and the two guide wheels 305 are in contact with the arch frame 1; the elastic member 303 is supported and guided by the guide wheel 305 to avoid friction damage between the elastic member 303 and the arch frame 1.

[0042] It also includes an arc block 401 and a convex block 402 ; an arc block 401 is fixedly connected to each side of the scraper 304 ; and a convex block 402 cooperating with the arc block 401 is arranged on the arch frame 1 .

[0043] The two elastic members 303 are rotatably connected to the scraper 304 via a torsion spring shaft.

[0044] The scraper 304 is arranged to be perpendicular to the arc surface of the arch frame 1 , and a convex tooth structure is arranged at the end close to the arch frame 1 , and a groove matching the tooth plate shape is opened on the water-absorbing sponge 101 .

[0045] It also includes an installation box 501, an electric shaft 502 and a limiting cloth 503; the installation box 501 is bolted to the right of the arch frame 1; the electric shaft 502 is connected to the installation box 501; the limiting cloth 503 is wound around the middle of the electric shaft 502; the free end of the limiting cloth 503 is fixedly connected to the fixed end of the elastic member 303.

[0046] The limiting cloth 503 is configured as a waterproof cloth to prevent the water squeezed out of the water-absorbing sponge 101 from flowing through the limiting cloth 503 and flowing back into the water-absorbing sponge 101 .

[0047] After impurities such as broken soil and stones fall on the water-absorbing sponge 101, it is inevitable that some impurities will remain on the water-absorbing sponge 101 and will not roll off directly. In order to prevent the accumulation of impurities on the water-absorbing sponge 101 and affect the water-absorbing and splash-proof effect of the water-absorbing sponge 101, the air pump 104 is first controlled by timing to deflate the arched airbag 102 through the air guide tube 103 to restore the water-absorbing sponge 101 to its original position, and then the electric rope reel 301 is started to reel the pull rope 302, so that the pull rope 302 moves in the arched groove, driving the elastic member 303 and the scraper 304 to move along the arched groove on the arch frame 1, and at the same time the electric shaft 502 is started to release the limiting cloth 503, and then the elastic member 303 drives the limiting cloth 503 to unfold along the arch frame 1, When the scraper 304 drives the arc block 401 to move through a plurality of convex blocks 402 of different sizes, the arc block 401 intermittently contacts and is squeezed by the convex blocks 402, so that the arc block 401 drives the scraper 304 to move, and the elastic member 303 is deformed and accumulates elastic force. When the arc block 401 is not squeezed by the convex blocks 402, the elastic member 303 releases the elastic force to make the scraper 304 move in the opposite direction and reset, so that the scraper 304 moves back and forth left and right. If there are large impurities accumulated and stuck on the through-type channel of the arch frame 1 before, the scraper 304 with a toothed plate shape can move back and forth left and right to move the stuck large impurities. Because the large impurities are generally a mixture of soil and sand, the stirring can destroy the mixture, so that the large impurities fall and are collected. The scraper 304 moves along the arched groove on the arch frame 1, and the scraper 304 moves along the surface of the water-absorbing sponge 101. During the process of the scraper 304 adhering to the right half of the water-absorbing sponge 101 and moving upward, if a large amount of impurities are accumulated on the water-absorbing sponge 101, as the scraper 304 scrapes the impurities and accumulates them in the angle formed between the scraper 304 and the water-absorbing sponge 101, after the total weight of the impurities exceeds a predetermined value, the end of the scraper 304 close to the water-absorbing sponge 101 is squeezed, and then the torsion spring shaft at the connection between the elastic member 303 and the scraper 304 is twisted, so that the scraper 304 rotates, and the end of the scraper 304 close to the water-absorbing sponge 101 begins to deflect downward, thereby contacting the absorbent sponge 101. The water sponge 101 is separated, and the deflection separation will form a channel between the scraper 304 and the water-absorbing sponge 101. During the scraping process of the scraper 304, the originally scattered impurities such as mud, soil and soil are gathered together to form a group. These mud, sand and soil that have gathered into a group will roll directly from the formed channel to the guide plate 3, and then fall into the collection box 201, thereby completing the collection of impurities such as mud, soil and soil, and avoiding the scraper 304 forcibly driving the accumulated impurities to move, causing damage to the water-absorbing sponge 101; when the scraper 304 is attached to the left half of the water-absorbing sponge 101 and moves downward, the scraper 304 scrapes off the impurities accumulated on the water-absorbing sponge 101, so that the impurities fall and are collected in the collection box 201 on the left side;When the scraper 304 is attached to the left half of the absorbent sponge 101 and moves downward, because the speed of the electric shaft 502 releasing the limiting cloth 503 is coordinated with the speed of the electric rope reel 301 to reel it in, the electric rope reel 301 and the electric shaft 502 work together to control the movement of the scraper 304, and the scraper 304 will not naturally slide down quickly due to gravity.

[0048] When the scraper 304 moves to the end of the stroke, the limiting cloth 503 unfolds in an arch shape to cover the water-absorbing sponge 101. At this time, the air pump 104 is started again to inflate the arched airbag 102 through the air guide tube 103, so that the arched airbag 102 expands, and then the water-absorbing sponge 101 is squeezed by the arched airbag 102 and the limiting cloth 503. The pull rope 302 and the limiting cloth 503 themselves can hardly be elastically deformed, so they will not be deformed and stretched, so that the water in the water-absorbing sponge 101 is squeezed out and flows along the surface of the water-absorbing sponge 101 to the guide plates 3 on both sides, and finally collected in the collection boxes 201 on both sides, so as to avoid the water-absorbing sponge 101 from working for a long time and absorbing water, resulting in a decrease in the anti-splashing effect. The water-absorbing sponge 101 is limited by the limiting cloth 503 to avoid the water-absorbing sponge 101 from being damaged by contact and extrusion with the tunnel wall.

[0049] Then, the air pump 104 is restarted to deflate the arched airbag 102 through the air pump 104, so that the arched airbag 102 and the water-absorbing sponge 101 are restored to the initial working state, and then the electric shaft 502 is controlled to start to reel in the limiting cloth 503, and the electric rope reel 301 releases the pull rope 302, so that the scraper 304 moves in the opposite direction and resets. At this time, during the movement of the scraper 304 in contact with the right half of the water-absorbing sponge 101, in the process of releasing the accumulated impurities before, some of the soil and sand that are not clumped or very loose will fall back on the surface of the water-absorbing sponge 101, and then the scraper 304 is reset to scrape the impurities remaining on the right half of the water-absorbing sponge 101 and collect them in the collection box 201, so as to avoid the impurities from accumulating on the water-absorbing sponge 101 for a long time, causing the water-absorbing sponge 101 to become hardened, which affects the next use of the water-absorbing sponge 101.

[0050] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solutions obtained by equivalent replacement or equivalent transformation shall fall within the protection scope of the present invention.
