Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy equipment, in particular to a water conservancy detection alarm instrument. Background Art

[0002] In water conservancy equipment, a water flow velocity alarm is usually required. However, due to debris and floating objects in the water, it is easy for the water flow velocity to be detected incorrectly.

[0003] In order to deal with such problems, Chinese patent CN218956608U, a water conservancy detection alarm, points out that by installing a filter net on the water hole, it is possible to prevent debris in the water flow from covering the water flow sensor. At the same time, the water fluctuation in the water area drives the float to float up and down, driving the second shaft to rotate and the connecting shaft to rotate at the same time. The cleaning rod rotates around the connecting shaft to remove foreign matter on the filter net, thereby preventing the water flow sensor from being unable to monitor the flow rate due to obstruction by debris.

[0004] Although the above method has played a certain role, there are still some problems. Figure 1 , Figure 2 , Figure 5 As shown in FIG6 , the device does not consider the problem of water pressure. The device may not be able to achieve the problem of driving the float ball to float up and down through the fluctuation of water in the water area, driving the second shaft to rotate and driving the connecting shaft to rotate at the same time, and removing the foreign matter on the filter screen by rotating the cleaning rod around the connecting shaft.

[0005] Therefore, in order to solve the problem of accumulation of debris and floating objects on the filter net, a water conservancy detection alarm is proposed. Utility Model Content

[0008] An opening is provided in the middle of the surface of the column;

[0009] A cleaning driving structure for cleaning the surface of the filter screen is installed in the column, wherein the cleaning driving structure extends outwards along the opening and fits against the outer surface of the column.

[0010] Through the above technical solution, further, the cleaning drive structure includes a motor, and the motor is fixed by a mounting plate fixedly installed in the column;

[0011] A lead screw is arranged at the output end of the motor, a movable block is arranged on the surface of the lead screw, an L-shaped scraper is arranged on the surface of the movable block, the L-shaped scraper extends outward along the opening, and a scraper pad is installed on one side of the end of the L-shaped scraper.

[0012] Furthermore, the scraper pad has an arc-shaped cross section that is consistent with the curvature of the column.

[0013] As a preferred technical solution, the scraper pad has protrusions evenly distributed on one side of the column, and a through hole is opened on the top of the protrusion, and the through hole passes through the L-shaped scraper.

[0014] Furthermore, a battery is installed on the inner top of the column.
