Description

Technical Field

[0001] The present invention relates to the technical field of water level early warning, and more particularly to a hydrological and water resource water level early warning device. Background Art

[0002] Hydrological resources refer to various phenomena such as the changes and movements of water in nature, including the formation, circulation, spatiotemporal distribution, chemical and physical properties of water, and the relationship between water and the environment. Therefore, when monitoring the water level of relevant areas, it is necessary to combine the water level early warning device at the relevant height for real-time monitoring. The early warning device can make real-time height adjustments according to the changes in the water level, so as to directly detect the water level of the water resource area and ensure the stability of water level monitoring and early warning of water resources. In summary, the inventors have found that the existing water level warning device has the following main defects: since the monitoring buoy of the current water level warning device is very easy to swing left and right when moving according to the water level changes, and its small changes in water level after slight floating are difficult to be monitored, it will reflect that the current water level warning device is difficult to judge the water level data with small changes, which will make it difficult to adjust the accuracy of flood control projects in water resource areas in the later stage, and indirectly reduce the construction accuracy of flood control projects.

[0033] Among them, the measuring rod 63 of the monitoring structure 6 is vertically installed through the vertical rail 5 of the sedimentation column 2 and electrically connected to the alarm module 3 and the solar panel 4. The buoy 61 will drive the light horizontal column 62 to slide on the measuring rod 63 as the water level rises or falls, so that the contact ring 628 of the light horizontal column 62 can monitor the water level data through the monitoring pulley 627 and the monitoring module 626, and at the same time, the bottom trigger module 65 is used to alarm the low water level through the alarm module 3.

[0034] The positioning body 1 and the sedimentation column 2 are perpendicular to each other, and the vertical rail 5 on the side of the sedimentation column 2 is rectangular in shape and matches the shape of the monitoring structure 6 .

[0035] Among them, the buoy 61 is circular in shape and is arranged at the front end of the light transverse column 62 to form a cross-splicing, so that the other end of the light transverse column 62 is stably installed in the measuring rod 63 area, and the connecting plate 64 and the measuring rod 63 are buried with power lines to supply power to the trigger module 65 and the light transverse column 62 through the power module 66.

[0036] Among them, the balance block 621 is provided with two blocks on the edge of the upper part of the column 622, which are in parallel contact with the inside of the sedimentation column 2. The adsorption block 623 is arranged at the edge of the splicing ring 624 and the shape of the splicing ring 624 is consistent with the shape of the buoy 61. The positioning column 625 limits the position of the monitoring module 626 and the monitoring pulley 627 to the edge of the contact ring 628 and contacts the measuring rod 63.

[0037] The buoy 61 is provided with a rubber disc 611 , a solid rod 612 is provided in the upper center area of ​​the rubber disc 611 , and a threaded rod 613 is welded to the upper end of the solid rod 612 , the threaded rod 613 and the locking sleeve 614 are matched with each other, and a control body 615 is installed on the top of the locking sleeve 614 .

[0040] The central protrusion 6111 is a solid circular shape and the restraining blocks 6113 on the edge of the disk body 6112 are solid trapezoidal shapes and are provided with four blocks for installation in four directions.

[0041] Specific functions and operation procedures of this embodiment: In the present invention, the hydrological and water resource water level warning device sets the vertical rail 5 in the water resource environment through the positioning body 1 and the sedimentation column 2, and then the monitoring structure 6 floats on the surface of the water resource according to the water level height. At the same time, the alarm module 3 and the solar panel 4 at the upper end of the sedimentation column 2 are also above the water resource. Then the measuring rod 63 of the monitoring structure 6 will be vertically installed inside the vertical rail 5, and at the same time, the electrical connection with the alarm module 3 will be completed through the power module 66, and then one end of the light horizontal rod 62 will be embedded in the measuring rod 63, and the other end can be connected to the floating rod 63 through the adsorption block 623 and the splicing ring 624 of the column 622. The buoy 61 is fixedly connected, so when the water level changes, the buoy 61 can carry the light horizontal column 62 to slide on the measuring rod 63, so that the column 622 of the light horizontal column 62 can slide in a balanced manner in the vertical rail 5 area through the balance blocks 621 on both sides. During the process, the monitoring module 626 and the monitoring pulley 627 and the contact ring 628 on the positioning column 625 are used to displace on the surface of the measuring rod 63, so that the displaced height data can be input into the alarm module 3 area through the power module 66 at the upper end of the measuring rod 63. Then, the current data can be compared according to the alarm module 3. If it meets the stable state, no alarm will be issued. At the same time, according to the effects of stable sliding and contrast, the accuracy of monitoring and early warning of water resource water level height can be effectively improved. Then, if the water level drops abnormally, the light horizontal column 62 will drop rapidly with the buoy 61, so that the lower layer of the column 622 will collide with the upper end of the trigger module 65. Therefore, after the trigger module 65 is hit, it will immediately trigger the alarm module 3 to alarm through the internal power circuit, thereby achieving a rapid early warning effect. The rubber disk 611 of the buoy 61 can maintain a parallel state through the mutual restraint and pulling of the central protrusion 6111 of the lower disk 6112 and the four restraint blocks 6113 on the edge. It floats on the surface of the water resources, preventing the occurrence of rollover instability. The solid rod 612 at the upper end of the rubber disc 611 can push the threaded rod 613 from under the splicing ring 624, so that the threaded rod 613 can cross the splicing ring 624. Then the control body 615 carries the locking sleeve 614 and is inserted from above the splicing ring 624. The rubber disc 611 can be positioned in the front end area of ​​the light horizontal column 62 by using rotary locking, achieving a stable cross-fixing effect and avoiding monitoring instability caused by excessive looseness. At the same time, the detachable effect can improve the convenience of subsequent disassembly, replacement and maintenance of the buoy 61 as a whole. Example

[0042] Figures 6 and 7 As shown: The present invention provides a hydrological and water resource water level early warning device. Its structure includes: the positioning body 1 is provided with a fixed block 15, the fixed block 15 passes through the corners of the parallel plate 13 through the through groove 14, and the central area of ​​the parallel plate 13 is connected with an adsorption plate 12 and a card block 11, and the card block 11 and the adsorption plate 12 are perpendicular to each other and are adsorbed and engaged at the lower end of the sedimentation column 2.

[0043] The number of the fixing blocks 15 and the number of the through slots 14 are the same and four groups are provided respectively. The through slots 14 are arranged one by one at the four corners of the parallel plate 13 . The adsorption plate 12 is a square shape with an area smaller than that of the parallel plate 13 .

[0044] Among them, the fixed block 15 is provided with an insertion body 151, the upper end of the insertion body 151 is connected to an overlapping plate 152, and the thread groove 153 is opened at the top center of the insertion body 151 through the overlapping plate 152, the thread groove 153 is connected to the locking rod 154 and the top of the locking rod 154 is connected to a rotating block 155.

[0045] Among them, the insertion body 151 is a solid rectangular strip and the surface of the top overlapping plate 152 is flattened to allow the thread groove 153 to be opened in a vertical direction. The shape of the rotating block 155 matches the shape of the insertion body 151 and can fit on the surface of the overlapping plate 152.

[0046] Specific functions and operation procedures of this embodiment: In the present invention, the parallel plates 13 of the positioning body 1 can be fixedly engaged with the lower end surface of the sedimentation column 2 by the adsorption plate 12 and the vertical block 11 in the center. At the same time, the parallel plates 13 can be combined with the weight of the sedimentation column 2 to vertically fall to the bottom area of ​​the water resource, and then the four through grooves 14 in the corner area are used to allow the four groups of fixed blocks 15 to penetrate and insert the interpenetrating bodies 151. After the four corners of the interpenetrating bodies 151 are inserted into the inner layer of the bottom of the water, a mutual restraint effect can be achieved, ensuring that the sedimentation column 2 can be used in a vertical and stable state to prevent the water waves from affecting the production. The overlapping plate 152 at the upper end of the insertion body 151 allows the thread groove 153 to be opened in the central area of ​​itself in a vertical direction, and then the locking rod 154 is vertically locked in. During the process, the cooperation of the rotating block 155 is used to achieve the effect of easy disassembly and assembly. At the same time, the rotating block 155 can use the cooperation of the locking rod 154 and the thread groove 153 to pull and push the insertion body 151 up and down, thereby improving the control stability of the insertion body 151. For this reason, the monitoring and early warning stability of the water level height of the water resources of the overall early warning device can be further improved.
