[0021] In order to achieve the above purpose and effect, the technical means and structure adopted by the utility model are described in detail in combination with the preferred embodiments of the utility model, and the characteristics and functions are described.

[0022] As shown in the accompanying drawings, Figs. 1-2 The utility model provides a kind of intelligent pipeline liquid adding automatic mixing device, comprising:

[0023] Main pipeline 1, main pipeline 1 is communicated with water supply pipeline, so that the water flow of water supply pipeline passes through main pipeline 1;

[0024] The liquid adding tank 2 is arranged above the main pipeline, and a liquid adding hole is arranged at the bottom of the liquid adding tank 2. The liquid adding hole is communicated with the top of the main pipeline 1 through a liquid adding pipeline 3. A one-way valve is arranged in the liquid adding pipeline 3 to prevent the liquid in the main pipeline 1 from moving to the liquid adding pipeline 3.

[0025] The opening and closing mechanism is arranged at one end of the liquid adding tank 2 and extends into the main pipeline 1. When the main pipeline 1 is not filled with liquid, the opening and closing mechanism is in a closed state, and the liquid in the liquid adding tank 2 cannot flow out of the liquid adding tank 2 through the liquid adding hole. When the liquid in the main pipeline 1 flows through the opening and closing mechanism, the opening and closing mechanism is triggered to be opened, and the liquid in the liquid adding tank 2 flows out of the liquid adding tank 2 through the liquid adding hole at the bottom of the liquid adding tank 2 and enters the main pipeline 1 through the liquid adding pipeline.

[0026] The staff can communicate the main pipeline 1 with the water supply pipeline in the coal mine, and add the dust fall agent in the liquid adding tank 2 to add the dust fall agent into the water flow when the water is sprayed and the dust is fallen in the coal mine, so as to improve the dust fall effect when the water is sprayed and the dust is fallen, improve the work visibility and environmental quality in the coal mine, and protect the health of the staff in the coal mine.

[0027] In another embodiment, the opening and closing mechanism includes a cover plate 41, a rack 42, a gear 43, a rotating shaft 44, a water wheel 45 and a spring 46. The cover plate 41 is arranged on the liquid adding hole and is in sliding sealing connection with the bottom of the liquid adding tank 2, so that the opening and closing of the liquid adding hole are realized by the sliding of the cover plate 41. The rack 42 is arranged at one end of the cover plate 41 and is in engagement with the gear 43. The first end of the rotating shaft 44 is coaxially connected with the gear 43, and the second end of the rotating shaft 44 extends into the main pipeline 1 and is coaxially connected with the water wheel 45. When the water flow enters the main pipeline 1, the water flow drives the water wheel 45 to rotate and further drives the gear 43 to rotate. The gear 43 drives the rack 42 to move when the gear 43 rotates, so as to drive the cover plate 41 to move away from the liquid adding hole. At this time, the liquid in the liquid adding tank 2 flows out of the liquid adding tank through the liquid adding hole and moves into the main pipeline 1 through the liquid adding pipeline 3. One end of the spring 46 is connected with the rack 42 or the cover plate 41, and the other end of the spring 46 is connected with the inner wall of the liquid adding tank 2. The spring 46 provides a force to the rack 42 or the cover plate 41 to restore the original position after the rack 42 or the cover plate 41 moves, so that the spring 46 drives the cover plate 41 to restore the original position and cover the liquid adding hole to close the liquid adding hole when there is no liquid in the main pipeline 1. The mechanical intelligent control of the addition of the liquid is realized without using electrical components, which meets the explosion-proof requirements of the underground environment.

[0028] Specifically, the bottom of the liquid adding tank 2 is inclined towards the liquid adding hole, so as to ensure that the liquid in the liquid adding tank 2 flows to the liquid adding hole.

[0029] In another embodiment, the top of the liquid tank 2 is provided with a liquid supplement hole, and a liquid supplement cover 21 is arranged on the liquid supplement hole. The staff can supplement liquid into the liquid tank 2 through the liquid supplement hole, and ensure the sufficiency of the liquid in the liquid tank 2.

[0030] In another embodiment, one side of the liquid tank 2 is provided with a liquid level pipe 5 with the same horizontal height as the liquid tank 2, the bottom of the liquid level pipe 5 is communicated with the bottom of the liquid tank 2, and the liquid level pipe 5 is a transparent structure. The staff can obtain the liquid level in the liquid tank 2 by observing the liquid level in the liquid level pipe 5, so that the staff can add liquid into the liquid tank 2 in time.

[0031] Specifically, the liquid level pipe 5 is provided with a scale line for identifying the volume of the liquid in the liquid tank 2 below the liquid level, so that the staff can more intuitively know the amount of the liquid in the liquid tank 2.

[0032] In another embodiment, the top of the liquid tank 2 is provided with an air inlet, the air inlet is connected with an air compression station arranged on the ground through an air inlet pipeline 6, and a pressure regulating valve is arranged on the air inlet. The staff can introduce gas into the liquid in the liquid tank 2, increase the air pressure above the liquid, give the liquid a downward force, and then speed up the flow of the liquid from the liquid tank 2 to the main pipeline 1, and the staff can also adjust the size of the air pressure through the pressure regulating valve to change the speed of the liquid flowing from the liquid tank 2 to the main pipeline 1.

[0033] Specifically, the top of the liquid tank 2 is provided with an air outlet 7, and a pressure relief valve is arranged on the air outlet 7. The staff can open the air outlet valve to make part of the gas in the liquid tank 2 leave the liquid tank 2, adjust the speed of the liquid flowing from the liquid tank 2 to the main pipeline 1, and make the air pressure inside and outside the device consistent when the device is not working, and ensure the service life of the device.
