It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0026] The utility model provides a tunnel water inrush monitoring device. By setting a filter net, when the flow is too large and carries large pieces of garbage and impurities, it is blocked by the filter net. At the same time, water flows into the detection probe from the gap of the filter net, and the detection probe performs detection, thereby reducing the problem of damage to the detection probe caused by excessive water flow colliding with the detection probe to a certain extent.

[0027] See also Figures 1 to 4 , the utility model provides a tunnel water inrush monitoring device, including a cylinder 6, a filter screen 8, a fixing rod 12, a flow meter 13, a detection probe 14, a top suspension assembly and a side support assembly;

[0028] A fixing rod 12 is suspended on the top of the tunnel body 1; a flow meter 13 is fixed to the bottom end of the fixing rod 12; a detection probe 14 is fixedly installed on the lower surface of the flow meter 13; wherein, there are two fixing rods 12, and the two fixing rods 12 are symmetrically arranged on both sides of the top wall of the inner wall of the tunnel body 1 with the vertical center line of the front of the tunnel body 1 as the axis of symmetry, and by setting two fixing rods 12, a stable installation of the detection probe 14 is achieved.

[0029] The cylinder 6 is sleeved on the outside of the flow meter 13 and the detection probe 14; a through hole is opened on the surface of the cylinder 6; the surface of the cylinder 6 and the outside of the through hole are covered and installed with a filter screen 8; the specific installation method of the filter screen 8 is as follows: the inner wall of the cylinder 6 is threaded with a bolt 4, and the bolt 4 is passed through the filter screen 8 to achieve the connection and fixation of the filter screen 8 and the surface of the cylinder 6.

[0030] Therefore, in the utility model, by setting a filter net 8, when the flow rate is too large and carries large pieces of garbage and impurities, the impurities are blocked by the filter net 8, and at the same time, water flows into the detection probe 14 from the gap of the filter net 8, and the detection probe 14 performs detection, which to a certain extent reduces the problem of excessive water flow colliding with the detection probe 14 and causing damage to the detection probe 14.

[0031] As a specific structure, the top surface of the cylinder 6 is connected to the top surface of the tunnel body 1 through a top suspension assembly; the side surface of the cylinder 6 is connected to the side wall of the tunnel body 1 through a side support assembly.

[0032] By providing the top suspension assembly and the side support assembly, a stable support function for the cylinder 6 can be achieved. In addition, the top suspension assembly and the side support assembly provided by the present application have the advantage of being easy to install.

[0035] In the present application, due to the sliding connection between the slide rod 15 and the threaded fixing cylinder 16, the top suspension assembly and the tunnel top wall are not rigidly connected by hardware, but have a margin for up and down movement. When the cylinder 6 is impacted by water flow, the cylinder 6 has a certain margin of movement, which buffers the force of the water flow impacting the cylinder 6 and extends the service life of the device.

[0039] Among them, the specific connection method between the fixed plate 2 and the connecting plate 5 is: an installation groove 10 is opened on the lower surface of the other end of the fixed plate 2, and the inner wall of the installation groove 10 overlaps with the other end of the connecting plate 5; the other end of the connecting plate 5 is threadedly installed with a first threaded rod 11, the first threaded rod 11 is screwed into the inner wall of the installation groove 10, and is connected with a nut 3.

[0040] Similarly, in the present application, due to the action of the slider 7, the side support assembly and the tunnel side wall are not connected by rigid hardware, but have a margin for up and down sliding movement. When the cylinder 6 is impacted by the water flow, the cylinder 6 has a certain movement margin, which buffers the force of the water flow impacting the cylinder 6 and extends the service life of the device.
