Description

Technical Field

[0001] The utility model relates to the technical field of water level measurement, and particularly relates to an Internet of Things type water level measurement device. Background Technique

[0002] The Internet of Things plays an important role in water level monitoring. Through the Internet of Things technology, real-time, remote and automatic monitoring of water levels can be achieved. Sensors are deployed at monitoring points, capable of continuously collecting water level data and transmitting the data to a cloud platform or a monitoring center through a wireless network, which brings many benefits: First, it improves the timeliness and accuracy of monitoring, can quickly detect abnormal changes in water levels, and provides key information for flood prevention early warning, water resource management, etc.; Second, it reduces the cost and risk of manual monitoring, eliminating the need for personnel to frequently visit dangerous or inaccessible monitoring points; Moreover, a large amount of real-time data helps with data analysis and prediction, providing a scientific basis for water conservancy planning and decision-making.

[0003] A Chinese patent with the authorization announcement number CN216770720U discloses a water level monitoring device based on the Internet of Things, including a fixed seat. A bolt is threadedly connected inside the fixed seat. A column is fixedly connected to the top of the fixed seat. A rope winding seat is fixedly connected to the side wall of the column. A crank is rotatably connected inside the rope winding seat. The column is fixedly connected to a cross bar through a set flange. A chute is opened inside the cross bar. A rectangular hole is opened at one end of the cross bar away from the column. By rotating the crank, the lifting rope drives the slider to slide on the sliding rod. The movement of the slider drives the position of the bottom of the adjusting rod to rise, driving the extension of the extension rod. After the water level sensor installed at the bottom of the extension rod measures the water level information, the information is transmitted to the information box, thereby realizing real-time monitoring of the water level. According to the change of the river water level surface, the extension of the extension rod is adjusted. The structure is simple, easy to use, and has high practicability.

[0004] During the actual use process of this device, the installation position is relatively fixed. Whenever a flood occurs and the water level is too high and submerges the highest end of the installed column, the water level sensor under the column will be submerged, resulting in its inability to work properly, or even the water level sensor being damaged.

Detailed implementation mode

[0025] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with the specific implementation mode.

[0026] As Figure 1-6 shown, an Internet of Things type water level measuring device includes a floating seat 1. A sealed cavity is provided inside the floating seat 1. The floating seat 1 is triangular. Mounting plates 11 are fixedly installed at the corners of the floating seat 1 away from its axis. Water level sensors 2 are fixedly installed at the bottoms of the plurality of mounting plates 11. A counterweight seat 3 is arranged at the bottom of the water level sensor 2. A connecting plate 4 is arranged at the back of the floating seat 1. Winding mechanisms 6 are symmetrically fixedly connected to the left and right of the upper end of the connecting plate 4. And a transmission mechanism 5 is located between the two winding mechanisms 6. The two winding mechanisms 6 are respectively bound to the counterweight seat 3 and the floating seat 1 through ropes.

[0027] In the present utility model, the floating seat 1 is set to achieve the purpose of floating. Water level sensors 2 for detecting the water level are installed at the corners of the top of the floating seat 1. In this way, the water level sensors 2 always float on the water surface through the floating seat 1, avoiding the water level sensors 2 being flooded when there is a flood. At the same time, the counterweight seat 3 is set to maintain the stability of the floating seat 1 in the water area and reduce the risk of the floating seat 1 tipping over. The connecting plate 4 is set to limit the floating seat 1 to prevent the floating seat 1 from being washed away by the water flow in the water area. At the same time, two winding mechanisms 6 are arranged on the connecting plate 4. One of the winding mechanisms 6 is used to automatically collect the floating seat 1 floating in the water area, and the other winding mechanism 6 is used to control the settlement of the counterweight seat 3.

[0028] Specifically, a connecting cylinder 12 is fixedly installed in the middle of the inner cavity of the floating seat 1. The head and tail ends of the connecting cylinder 12 both extend out of the inner cavity of the floating seat 1. A through first jack 121 is opened at the top end of the connecting cylinder 12. An inserting rod 31 adapted to the first jack 121 is fixedly installed in the middle of the top end of the counterweight seat 3. A second connection ring 311 is fixedly installed at the top end of the inserting rod 31. A first connection 13 is fixedly installed at a position near the middle of the top end of the floating seat 1. A first connection ring 131 is fixedly installed at the top end of the first connection 13.

[0029] The floating seat 1 is sleeved on the insertion rod 31 at the top of the counterweight seat 3 through 121. A second connecting ring 311 is fixedly installed on the insertion rod 31 and is bound to the rope on the winding mechanism 6. In this way, after the floating seat 1 enters the water, the settlement of the counterweight seat 3 can be controlled by the winding mechanism 6 on one side. At the same time, a first connection 13 is installed near the middle of the top end of the floating seat 1, and a first connecting ring 131 is fixedly installed at the top end of the first connection 13 and is bound to the rope of the winding mechanism 6 on the other side. In this way, the floating seat 1 can be controlled and retrieved by the winding mechanism 6 on the other side, which is convenient for retrieving the floating seat 1 from the water area later.

[0030] Specifically, installation grooves 32 are provided in the middle of the three end faces of the counterweight seat 3 away from its axis. Pin rods 321 are fixedly installed on the three installation grooves 32. Three hinge seats 14 are annularly arranged at the bottom end of the floating seat 1 away from its axis. Hooks 141 are rotatably installed on the three hinge seats 14. One ends of the three hooks 141 away from the three hinge seats 14 are respectively hooked to the three pin rods 321. A plurality of pulleys 33 are annularly arranged at the bottom end of the counterweight seat 3 away from its axis;

[0031] After the floating seat 1 enters the water, rotate the plurality of hooks 141 respectively to release the limit of the plurality of hooks 141 from the pin rods 321. Then, control the settlement of the counterweight seat 3 through the winding mechanism 6 on one side. After the counterweight seat 3 sinks to the bottom of the water, it is equivalent to an anchor, which can increase the stability of the floating seat 1 and reduce the risk of the floating seat 1 being overturned by water waves. At the same time, through the pulleys 33 annularly arranged at the bottom end of the counterweight seat 3, when the floating seat 1 has not entered the water, the setting of the pulleys 33 facilitates the transportation of the entire device.

[0032] Specifically, two sockets 15 are symmetrically installed at the back end of the floating seat 1. Through holes two 151 are provided at the top ends of the two sockets 15. Two nail rods 41 are symmetrically installed at the bottom end of the connecting plate 4. The connecting plate 4 is inserted into the two through holes two 151 through the two nail rods 41;

[0033] By setting the connecting plate 4, when not in use, the connecting plate 4 is inserted into the two sockets 15 behind the floating seat 1 through the nail rods 41. During use, the connecting plate 4 is removed and inserted into the specified fixed area to prevent the floating seat 1 from being washed away by the water flow in the water area. At the same time, two winding mechanisms 6 are provided on the connecting plate 4. One of the winding mechanisms 6 is used to automatically retrieve the floating seat 1 floating in the water area, and the other winding mechanism 6 is used to control the settlement of the counterweight seat 3.

[0034] Specifically, the transmission mechanism 5 includes a servo motor 51. The servo motor 51 is fixedly installed in the middle of the top end of the connecting plate 4. The output shaft of the servo motor 51 is fixedly installed with a first bevel gear 52 through a coupling. On both sides of the two fixed seats 61 along their height directions, winding rollers 62 are respectively rotatably installed. On the end faces of the two winding rollers 62 close to each other, second bevel gears 53 are fixedly installed. The two second bevel gears 53 are respectively meshed with the first bevel gear 52. The two winding rollers 62 are respectively tied to the first connecting ring 131 and the second connecting ring 311 through ropes.

[0035] By setting the servo motor 51, the output shaft of the servo motor 51 rotates the first bevel gear 52, so as to respectively rotate the ropes on the two winding rollers 62 through the two second bevel gears 53 for winding.

[0036] Furthermore, the winding mechanism 6 includes two fixed seats 61 and four threaded rods 63. The four threaded rods 63 are symmetrically installed in pairs on both sides of the top end of the connecting plate 4 away from its middle. On both sides of the two fixed seats 61 along their height directions, sliding rings 64 are symmetrically installed. The two fixed seats 61 respectively slide on the threaded rods 63 through a plurality of sliding rings 64. Threaded knobs 65 are threadedly installed on the four threaded rods 63. The top ends of the four threaded knobs 65 are respectively in contact with the bottom ends of the four sliding rings 64.

[0037] Turn the two threaded knobs 65 on one side. The two threaded knobs 65 on one side push up the two sliding rings 64 on one side to make the fixed seat 61 on one side move upward, so that the second bevel gear 53 on the fixed seat 61 on one side is disengaged from the first bevel gear 52. On the contrary, turn the two threaded knobs 65 on one side downward to make the second bevel gear 53 on the fixed seat 61 on one side descend and mesh with the first bevel gear 52. In this way, the servo motor 51 drives the winding roller 62 on one side to rotate, respectively controlling the winding of the ropes on the winding roller 62.

[0038] It should be particularly noted that the specific installation methods, circuit connection methods and control methods of the multiple water level sensors 2 and the servo motor 51 adopted in the present invention are all conventional designs, and the present invention will not elaborate in detail.
