[0021] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0022] The utility model embodiment discloses a multi-connection sewage conveying device for coal mining.

[0023] The utility model provides Figure 1-3 The shown device is a multi-connection sewage conveying device for coal mining, comprising a fixed shell 1, a conveying pump 2 is installed inside the fixed shell 1, both ends of the conveying pump 2 are fixedly connected with fixed pipes 3, the fixed pipe 3 passes through the fixed shell 1, and two mounting grooves 12 are symmetrically provided on the inner wall of the fixed pipe 3, and arc plates 13 are embedded in the two mounting grooves 12, and an inclined surface is provided on the side of the arc plate 13 close to the inner wall of the fixed shell 1, a guide rod 14 is fixedly connected to the outer wall of one side of the arc plate 13, and the other end of the guide rod 14 passes through the outside of the fixed pipe 3 and is embedded in the fixed pipe 3, and a barb 15 is provided on the outer wall of the other side of the arc plate 13, and a spring 16 is nested on the guide rod 14, and the spring 16 is pressed between the arc plate 13 and the inner wall of the mounting groove 12.

[0024] The utility model discloses a multi-connection sewage conveying device for coal mining, wherein a pull ring 17 is fixedly connected to the engaging end of a guide rod 14, and a rubber sleeve is nested on the pull ring 17, so that the guide rod 14 and the arc plate 13 can be conveniently driven to move upward through the pull ring 17, thereby improving the convenience of use.

[0025] The utility model discloses a multi-connection conveying device for sewage in coal mining. A limit plate 4 is arranged inside a fixed pipe 3. A sealing ring 5 is arranged on the limit plate 4 to improve the sealing performance of the pipe connection and avoid water seepage and leakage.

[0026] The utility model discloses a multi-connection sewage conveying device for coal mining, wherein a support plate 6 and a fixed plate 7 are respectively provided on the outer wall of a fixed shell 1, a screw 8 is threadedly connected to the fixed plate 7, a rotating seat 9 is provided at one end of the screw 8, a rotating head 10 is provided at the other end of the screw 8, a pressing plate 11 is provided on the rotating seat 9, which can provide a certain supporting effect for the connected pipes, avoid bending of the connected pipes, and affect the fixing effect of the connected pipes, and at the same time, can further improve the fixing effect of the pipes.

[0027] The utility model discloses a multi-connection conveying device for sewage in coal mining, wherein the support plate 6 and the pressure plate 11 are both arc-shaped structures, and anti-skid pads are bonded to the fitting end surfaces of the support plate 6 and the pressure plate 11, and the anti-skid pads are rubber pads. The arc-shaped structure can fit more closely with the pipeline, and the anti-skid pads can improve the fixing effect of the pipeline.

[0028] The utility model discloses a multi-connection sewage conveying device for coal mining, wherein a door panel is installed on a fixed shell 1, a heat dissipation window 18 is provided on the door panel, a filter screen is installed in the heat dissipation window 18, the heat dissipation window 18 can conveniently provide heat dissipation for a conveying pump 2, thereby improving the working continuity of the conveying pump 2, and the filter screen can prevent external dust and impurities from entering the interior of the fixed shell 1 and affecting the operation of the conveying pump 2.

[0029] When in use, after placing the device at the designated position, place the pipe to be connected on the support plate 6 and insert it into the fixed pipe 3. At this time, the pipe will contact the curved plate 13. Since the end of the curved plate 13 that contacts the pipe is provided with an inclined surface, when the external force continues to be applied to the pipe, the pipe will push the curved plate 13 to move upward until the pipe moves to the limiting plate 4. At this time, the curved plate 13 will move downward under the elastic action of the spring 16, so that the pipe can be limited by the barb 15 to avoid separation between the pipe and the fixed pipe 3. Then, the rotating head 10 is rotated to drive the screw 8 to rotate. Since the screw 8 is connected to the pressure plate 11 through the rotating seat 9, the screw 8 can drive the pressure plate 11 to descend during the rotation process, thereby providing a further fixing effect for the pipe. When the pipe needs to be removed, first, the pressure plate 11 is driven to rise by rotating the screw 8, and then the door panel is opened, and the pull ring 17 is pulled to drive the curved plate 13 and the barb 15 to separate from the pipe. The overall operation of the device is convenient, and the connection and separation efficiency between the delivery pump 2 and the pipe is high.
