DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Embodiment 1

[0040] like Figure 1 , Figure 5 , Figure 7 and Figure 8As shown, the present invention provides a temporary intelligent filling device for upper corners of a mine, comprising an outer air bag 1; a central air column 2 is fixedly arranged at a middle position in the outer air bag 1; a reinforced air bag column assembly 3 is arranged inside the outer air bag 1, and the reinforced air bag column assembly 3 is connected to the central air column 2; an inflation port seat assembly 4 is arranged on the outer wall of the outer air bag 1; an inflation pipe assembly 5 is arranged outside the outer air bag 1, and the inflation pipe assembly 5 movably penetrates the inflation port seat assembly 4 and is connected to the central air column 2; a plurality of pressure sensors 6 are arranged, and the plurality of pressure sensors 6 are arranged on the inner wall of the central air column 2 away from the inflation port seat assembly 4;

[0041] The reinforced airbag column assembly 3 includes two airbag columns 31 spaced apart from each other along the outer peripheral wall of the central air column 2. The airbag columns 31 are connected to the central air column 2. One end of the two airbag columns 31 away from the central air column 2 is respectively located at two opposite ends of the outer airbag 1. A compensation airbag column 32 is movably arranged in one end of the airbag column 31 away from the central air column 2.

[0042] The inflation tube assembly 5 includes an outer tube 51 penetrating the inflation port seat assembly 4, an inflation tube 52 movably penetrating the outer tube 51, the inflation tube 52 is movably connected to the central air column 2, and a tracheal blocker 53 is provided at one end of the inflation tube 52 away from the central air column 2.

[0043] When in use, the outer airbag 1 is placed vertically at the position of the upper corner, and the central air column 2 is located directly above the inflation port seat assembly 4 (at the same time, the inflation port seat assembly 4 is fixedly supported on the working surface away from the end of the outer airbag 1); by setting an air pump externally connected to the outside of the outer airbag 1 (that is, remove the trachea blocker 53 at the end of the inflation tube 52 away from the central air column 2, so that the end of the inflation tube 52 away from the central air column 2 is connected to the air pump externally connected to the outside of the outer airbag 1), the high-pressure gas passes through the inflation tube 52 in the inflation tube assembly 5 and the inflation port seat assembly 4 in turn to directly inflate the interior of the outer airbag 1, so that the upper corner can be blocked by the inflated outer airbag 1.

[0044] When it is necessary to strengthen the support for the top of the outer airbag 1, the inflation tube assembly 5 can be passed through the inflation port seat assembly 4 and connected to the central air column 2 (that is, the inflation tube 52 can be passed through the inflation port seat assembly 4 and connected to the central air column 2), and the air pump externally connected to the outer airbag 1 can be started to allow the high-pressure gas to pass through the inflation tube 52 and the central air column 2 in turn and enter the two airbag columns 31. As the gas continues to enter, the compensation airbag column 32 in the end of the central air column 2 can be pushed out of the airbag column 31, so that the compensation airbag column 32 can be made to conflict with the outer airbag 1, thereby strengthening the support and sealing effect, that is, the compensation airbag column 32 can play a compensating role in the sealing of the outer airbag 1.

[0045] The setting of the pressure sensor 6 can detect the pressure of the position of the outer airbag 1 when it is blocked, that is, the pressure sensor 6 can detect the pressure when the outer airbag 1 and the upper corner are blocked (that is, when the outer airbag 1 and the upper corner are tightly fitted, the pressure detected by the pressure sensor 6 is relatively large; when the outer airbag 1 and the upper corner are loosely fitted or not fitted, the pressure detected by the pressure sensor 6 is relatively small or there is no pressure, which can control the start of the air pump connected to the outside of the outer airbag 1 for inflation); this is the prior art (that is, the pressure sensor senses the change in pressure and converts the pressure signal into an electrical signal; by sending a signal to the air pump controller, the air pump controller will start the air pump connected to the outside of the outer airbag 1 for inflation after receiving the signal), so it will not be elaborated here.

[0046] Embodiment 2

[0048] When it is necessary to strengthen the support for the top of the outer airbag 1, the inflation tube assembly 5 can be passed through the inflation port seat assembly 4 and connected to the inflation tube connecting tube 21 in the central air column 2, and the air pump externally connected to the outer airbag 1 can be started to allow the high-pressure gas to pass through the inflation tube 52, the inflation tube connecting tube 21, and the central air column 2 in turn and enter the two airbag columns 31. As the gas continues to enter, the compensation airbag column 32 in the end of the airbag column 31 away from the central air column 2 can be pushed out, so that the end of the compensation airbag column 32 away from the airbag column 31 can be made to contact the inner wall of the outer airbag 1, thereby strengthening the support and sealing effect.

[0049] A one-way air valve is arranged in the inflation tube connecting tube 21 , so that after the inflation of the compensation airbag column 32 is completed, when the inflation tube 52 is separated from the inflation tube connecting tube 21 , no air leakage will occur in the compensation airbag column 32 .

[0052] The inflation window 43 to be used can be selected according to the need for sealing the upper corner, that is, when only the outer airbag 1 needs to be inflated, the inflation windows 43 located on both sides can be used to remove the external threaded blocking column 442 on one of the window plugs 44 (that is, the external threaded blocking column 442 can be rotated from the middle tube 441, and the external threaded blocking column 442 can be separated from the threaded seat 443 at the corresponding position); then the inflation tube 52 is passed through the middle tube 441 and threadedly connected with the threaded seat 443 at the corresponding position, so that the inflation tube 52 can be connected to the inner cavity of the outer airbag 1, and the air pump connected to the outside of the outer airbag 1 is started, so that the high-pressure gas can enter the outer airbag 1 through the inflation tube 52 (at this time, the central air column 2, the airbag column 31 and the compensation airbag column 32 are not inflated).

[0053] When it is necessary to inflate the airbag column 31 and the compensation airbag column 32, it is only necessary to remove the external threaded blocking column 442 on the window blocking 44 at the middle position, pass the inflation tube 52 through the middle tube 441 and threadably connect it with the threaded seat 443 at the corresponding position, and then threadably connect it to the inflation tube connecting tube 21 at the end away from the central air column 2. Start the air pump externally connected to the outer airbag 1, so that the high-pressure gas can enter the central air column 2, the airbag column 31 and the compensation airbag column 32 through the inflation tube 52 and the inflation tube connecting tube 21 in turn; when the airbag column 31 and the compensation airbag column 32 are filled with gas, they can play a role in strengthening the support of the outer airbag 1.
