Description

Technical Field

[0001] The utility model provides a water resource water level early warning device, belonging to the technical field of water resource monitoring. Background Art

[0002] With the development of social economy and population growth, the demand for water resources is increasing day by day, and the rational use and management of water resources has become crucial. Water level is one of the important indicators to measure the storage and management of water resources. By real-time monitoring of water level data, we can effectively prevent floods, protect the ecological environment and ensure people's living water.

[0003] In traditional water level monitoring and early warning devices, water level monitoring and early warning are often carried out by setting up a water level monitoring box; its principle is to make the water level monitoring structure in the water level monitoring box change synchronously with the change of the liquid level of the external water resources. Therefore, a water inlet hole connected to the external water resources needs to be set on the water level monitoring box. In order to ensure that external debris does not enter the monitoring box, the water inlet hole is usually set smaller, and the smaller water inlet hole plays the role of filtering debris while ensuring that the water inside and outside the monitoring box are connected. However, under the long-term use of the water level monitoring box, the water inlet hole is often blocked by impurities or pollutants, affecting the consistency of the liquid level in the monitoring box with the external liquid level, thereby affecting the monitoring and early warning of the water level. The water inlet hole is usually located in the water body, which is very troublesome to clean. In view of this, a water resource water level early warning device is needed, which can quickly and conveniently clean the water inlet hole to avoid the accuracy of water level monitoring and early warning.

[0018] The utility model is further described below in conjunction with the accompanying drawings.

[0019] according to Figure 1-4 As shown: the utility model provides a water resource water level warning device: comprising a mounting seat 1, the mounting seat 1 is fixedly connected with a support frame 2 and a water level monitoring box 3 in sequence upward; a water inlet hole 7 is provided at the bottom of the water level monitoring box 3, a vent hole 4 is provided at the top of the water level monitoring box 3, and a water level monitoring structure is arranged in the water level monitoring box 3; a dredging structure is arranged in the water level monitoring box 3 for sliding up and down, and the dredging structure corresponds to the water inlet hole 7; a chute 13 is provided in the wall of the water level monitoring box 3, and a sliding structure fixedly connected to the dredging structure is slidably arranged in the chute 13; a limit block 17 fixedly connected to the sliding structure is arranged above the water level monitoring box 3, and a spring 16 sleeved on the sliding structure is arranged below the limit block 17. It should be noted that when the water level monitoring box 3 is fixedly installed in the water body by using the mounting seat 1, there is a sufficient distance between the upper end of the water level monitoring box 3 and the water body to prevent the controller 5 and the alarm speaker 6 from being submerged by water, and it is convenient for the staff to operate and press the limit block 17 outside the water body.

[0020] The present application sets a sliding structure inside the wall of the water level monitoring box 3, which can control the sliding structure to slide outside the water body, and utilizes the sliding structure to drive the dredging structure to rise and fall, thereby clearing out impurities blocked in the water inlet hole 7, so that the liquid levels inside and outside the water level monitoring box 3 can be consistent in real time, thereby not affecting the accuracy of water level monitoring and early warning.

[0021] The water level monitoring structure includes a float 11, a protective cover 12, and a displacement sensor 18; the float 11 is located in the water level monitoring box 3, the protective cover 12 is fixedly arranged on the float 11, and the displacement sensor 18 is located in the protective cover 12, and the protective cover 12 can protect the displacement sensor 18. A controller 5 connected to the displacement sensor 18 circuit is arranged on one side of the water level monitoring box 3, and an alarm speaker 6 connected to the controller 5 circuit is arranged on the controller 5. The displacement sensor 18 can transmit the displacement data to the controller 5, so as to monitor the water level, and when the water level exceeds the set value, the controller 5 can control the alarm speaker 6 to work, so as to give an early warning.

[0022] The dredging structure includes a lifting plate 9 and a dredging rod 8; the dredging rod 8 is fixedly connected to the bottom of the lifting plate 9, and the number and position of the dredging rod 8 correspond to the water inlet holes 7. One movement of the lifting plate 9 can enable the dredging rod 8 to clean all the water inlet holes 7, greatly improving the cleaning efficiency; a dredging groove 10 is opened on the lifting plate 9, which will not affect the normal passage of water.

[0023] The sliding structure includes a slider 14 and a connecting rod 15. The slider 14 is slidably arranged in the slide groove 13, and the connecting rod 15 is fixedly connected to the top of the slider 14; the upper end of the connecting rod 15 is fixedly connected to the limit block 17, and the spring 16 is sleeved on the connecting rod 15. The setting of the spring 16 can provide a rebound force for the sliding structure to return to its original position, so as to perform the next operation. The limit block 17 can be pressed conveniently by the staff, and the limit block 17 can prevent the spring 16 from being separated from the connecting rod 15.

[0024] A guide groove 19 is provided in the water level monitoring box 3 to connect the slide 13 with the inside of the water level monitoring box 3; a connecting column is provided in the guide groove 19, and the connecting column fixes the slider 14 and the lifting plate 9, thereby connecting the sliding structure and the dredging structure.

[0025] Principle of the utility model

[0026] When using the utility model, if Figure 1-2 As shown, the mounting base 1 is fixedly mounted in the water body, and the water in the water body can enter the water level monitoring box 3 through the water inlet hole 7; due to the setting of the vent hole 4, the water level in the water level monitoring box 3 can be the same as the external water level. Figure 3 As shown, the float 11 floats on the liquid surface in the water level monitoring box 3, so the displacement sensor 18 can change accordingly with the height change of the external water level. When the water level gradually rises, the vertical displacement of the displacement sensor 18 will also become larger and larger. When the water level height alarm setting value is reached, the controller 5 controls the alarm speaker 6 to work and sound an alarm, thereby warning the water level of the water inflow.

[0027] like Figure 3-4 As shown, when the water inlet 7 needs to be cleared, it is only necessary to press the limit block 17 downward above the water level monitoring box 3, that is, outside the water body, and the limit block 17 compresses the spring 16. At the same time, the sliding structure drives the lifting plate 9 to move downward until the dredging rod 8 is inserted into the water inlet 7, thereby pushing the debris stuck in the water inlet 7 to the outside of the water level monitoring box 3 to clear the blockage. Release the limit block 17, and under the action of the spring 16 rebound force, the sliding structure and the dredging structure return to their original positions and wait for the next work.

[0028] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
