[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0026] Embodiment 1:

[0027] See also Figure 1-4 , the utility model provides a technical solution:

[0028] A waterproof support device for a cave coal mine comprises an arc-shaped top 1 and a base 6. A T-stage 2 is fixed at the bottom end of the arc-shaped top 1. At the same time, a downwardly extending accommodating chamber 102 is provided on the inner wall of the top end of the arc-shaped top 1 for receiving seepage water at the top end of the support. The accommodating chamber 102 is connected with the inside of the T-stage 2 through two inclined tubes 11, so that the seepage water received can be discharged and collected downward through the inclined tubes 11. In order to enhance the overall stability and fixity of the support, a cross support frame 12 is arranged between the inclined tubes 11, and at the same time, the top end of the cross support frame 12 is fixed to the accommodating chamber 102, and the bottom end is fixed to the T-stage 2 to achieve upper and lower support. In order to continue to drain water, a telescopic hose 8 is installed on one side of the bottom end of the T-stage 2, and the telescopic hose 8 is connected with the inside of the base 6, so that the seepage water is finally discharged from the base 6 without affecting the overall construction and use. In order to facilitate the adjustment of the support height according to different environments, a telescopic adjustment support is arranged between the T-stage 2 and the base 6.

[0029] like Figure 2 As shown:

[0030] In order to collect seepage water, a water inlet 101 communicating with the accommodating cavity 102 is provided at the top of the arc-shaped top 1 , so that the seepage water can enter the accommodating cavity 102 through the water inlet 101 .

[0031] like Figure 1 , 4 As shown:

[0032] A water storage tank 21 is opened inside the T-stage 2, and the water storage tank 21 is connected to the inclined tube 11. The water in the accommodating chamber 102 enters the water storage tank 21 through the inclined tube 11 and is collected. In order to facilitate the timely discharge of seepage water after collection, a water outlet connected to the telescopic hose 8 is installed on one side of the inside of the water storage tank 21. At the same time, a pump 22 is installed at the water outlet. The pump 22 can pump out the water in the water storage tank 21 and quickly discharge it through the telescopic hose. In order to facilitate the knowledge of the water level and facilitate timely discharge, a water level gauge 9 for detecting the water level is installed on the outer wall of the T-stage 2.

[0033] like Figure 1 As shown:

[0034] A drainage hole 7 connected to the outside is provided on the base 6, so that the drainage hole is connected to the telescopic hose 8, so that the water pumped out by the pump 22 can be discharged from the drainage hole 7 in time, which is convenient and quick. At the same time, auxiliary support legs 5 are installed on both sides of the base 6 for auxiliary support. The mounting holes on the auxiliary support legs 5 can be fixed to the ground using ground nails to further enhance stability.

[0035] like Figure 1 As shown:

[0036] A reinforcing rod 10 fixed to the inner wall of the arc-shaped top 1 is provided on the outer side of the inclined tube 11 , so as to assist in strengthening the supporting strength of the arc-shaped top 1 .

[0037] Embodiment 2:

[0038] The difference from Example 1 is that ( Figure 3 As shown), the adjustment support includes an upper rod body 3 fixed to the T-stage 2, a lower rod body 4 fixed to the base 6, an electric telescopic rod 41 is installed inside the lower rod body 4, and the output end of the electric telescopic rod 41 is fixed to the inside of the upper rod body 3. The overall height adjustment can be driven by the extension and retraction of the electric telescopic rod 41.

[0039] How it works:

[0040] Personnel in the art program a controller (Siemens s7-200, not shown) to control various components on the support;

[0041] When water seepage occurs at the top, the seepage water enters the accommodating cavity 102 through the opening 101, and then flows into the water storage tank 21 inside the T-stage 2 through the inclined pipe 11 for collection. When the water level reaches the top of the water storage tank 21, the water level meter 9 (GX-701) alarms, and the seepage water is pumped out through the pump 22, discharged through the telescopic hose 8, and finally discharged to the outside through the drainage hole 7 on the base 6;

[0042] According to the demand, the upper rod body 3 and the parts above can be extended and retracted by the electric telescopic rod 41 to perform support operations, which is suitable for different heights. During the extension and retraction process, the telescopic hose 8 can also be extended and retracted according to the height without affecting drainage.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
