Abstract
Description
Technical Field
[0001] This utility model relates to the field of farmland irrigation equipment technology, specifically to a low-cost water depth monitoring mechanism. Background Technology
[0002] Water depth measurement is the process of determining the height of a point from the bottom to the surface and the planar position of that point. By measuring water depth, important data can be obtained regarding water structure, water resource reserves, landforms, the location of underwater obstacles, and the aquatic ecological environment. This provides important information for scientific research, surveying, and engineering design, promotes a scientific understanding and effective management of the water environment, and allows for the assessment of current water volume and appropriate actions in various water environments based on water depth values.
[0003] In farmland irrigation facilities, irrigation canals are usually set up. These canals guide and store water, playing a vital role in farmland irrigation. Water depth monitoring devices can effectively read the current water storage volume and obtain water consumption data over a period of time through real-time monitoring, making them crucial in farmland irrigation.
[0004] Currently, most water depth monitoring devices on the market use radar or ultrasound for detection. The installation height is first measured, and then the radar or ultrasound signal is emitted towards the water surface. The signal is reflected back to obtain the height value above the water surface. The controller subtracts the installation height from the height value above the water surface to obtain the current water level value. Although existing water depth monitoring devices can monitor water depth, their production cost is high, which is not conducive to their widespread promotion in the field of farmland water conservancy and is not conducive to improving the competitiveness of enterprises.

The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0018] In this invention, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment to other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this invention can be combined with other embodiments.
[0019] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
[0020] like Figure 1 and Figure 2 As shown, this utility model discloses a low-cost water depth monitoring mechanism, including an external controller, a heat source emitting column 1, and a heat source receiving column 2. The heat source emitting column 1 and the heat source receiving column 2 are arranged in parallel and are electrically connected to the external controller. The lower end of both the heat source emitting column 1 and the heat source receiving column 2 is provided with a mounting part, which is located at the bottom of the water. Multiple electric heating elements 11 are evenly spaced from top to bottom on the heat source emitting column 1, and multiple thermal sensing elements 21 that cooperate with the electric heating elements 11 are evenly spaced from top to bottom on the heat source receiving column 2. The thermal sensing elements 21 and the electric heating elements 11 are in one-to-one correspondence. At least the uppermost electric heating element 11 of the heat source emitting column 1 is located above the water surface, and at least the uppermost thermal sensing element 21 of the heat source receiving column 2 is located above the water surface.
[0021] By setting up the heat source emitting column 1 and the heat source receiving column 2, and taking advantage of the fact that heat conduction in water is slower than in air, the data measured by the heat sensing element 21 in the water is different from the data measured by the heat sensing element 21 above the water surface. Based on the set error range, it is determined whether the heat sensing element 21 at that position is exposed above the water surface. The change in heat energy within a certain unit of time can be measured. Using this change value, the change in water depth can be measured.
[0022] By combining the electric heating element 11 and the thermal sensing element 21, the traditional measurement methods using radar or ultrasound can be effectively replaced, thus reducing production costs and facilitating the promotion and application of the water depth monitoring device, thereby enhancing the product's competitiveness.
[0023] When in use, the mounting part is first covered and fixed by silt. At this time, the middle part will be submerged in water, and the top will be exposed to the air.
[0024] During the measurement process, the external controller controls multiple electric heating elements 11 on the heat source emission column 1 to emit heat one by one from top to bottom.
[0025] While emitting heat, the external controller controls multiple thermal sensing elements 21 on the heat source receiving column 2 to detect heat one by one from top to bottom. The electric heating element 11 and the thermal sensing element 21 work together to release heat layer by layer, and the thermal sensing element 21 of each layer records the measurement value of each layer.
[0026] This process is repeated from top to bottom.
[0027] The measured value is compared with a preset value to determine whether the point is in the air. If the value is equal to or close to the preset value, the point is in the water; if the value is greater, the point is in the air.
[0028] After judging each of the above measurements, we know which points are in the water, and then, based on the location and distance information of each point, we obtain the water depth at that measurement location.
[0029] The mounting part is the mounting plate 3, which is integrally formed with the mounting plate 3 of the heat source emitting column 1 and the mounting plate 3 of the heat source receiving column 2.
[0030] This structural design makes the relationship between the heat source emitting column 1 and the heat source receiving column 2 more stable, ensuring the stability of their relative positions.
[0031] The distance between the heat source emitting column 1 and the heat source receiving column 2 is between 0.5 cm and 2 cm.
[0032] By setting this range, the heat source emitting column 1 and the heat source receiving column 2 can be efficiently sensed, preferably within 1 cm.
[0033] The heat source emitting column 1 includes an emitting column housing, inside which is an emitting main control board. Multiple electric heating elements 11 are mounted on the emitting main control board. The emitting column housing has emitting holes that mate with the electric heating elements 11. The electric heating elements 11 are placed in the emitting holes and sealed around them with adhesive. Waterproof adhesive is applied to the electric heating elements 11. The heat source receiving column 2 includes a receiving column housing, inside which is a receiving main control board. Multiple thermal sensing elements 21 are mounted on the receiving main control board. The receiving column housing has receiving holes that mate with the thermal sensing elements 21. The thermal sensing elements 21 are placed in the receiving holes and sealed around them with adhesive. Waterproof adhesive is applied to the thermal sensing elements 21.
[0034] The use of waterproof adhesive can effectively prevent the electric heating element 11 and the thermal sensing element 21 from being affected by water in water, thus reducing the product's service life. Furthermore, the adhesive sealing prevents water from entering the outer shell of the transmitting column and the outer shell of the receiving column.
[0035] The receiver control board is also equipped with a wireless communication module, which enables the measurement data to be transmitted to a remote cloud service or remote terminal for real-time viewing by other personnel.
[0036] Both the heat source emitting column 1 and the heat source receiving column 2 are cylindrical in shape. The cylindrical design reduces the resistance of the product in flowing water.
[0037] The thermal sensing element 21 is a thermistor, and the electric heating element 11 is a heating wire or heating plate.
[0038] As can be seen from the above, the beneficial effects of this utility model are: by adopting its mechanism, it can effectively solve the problem that the existing water depth monitoring mechanism has high production costs and is not conducive to its widespread promotion in the field of farmland water conservancy. By using this product structure, the cooperation of the electric heating element 11 and the thermal sensing element 21 can effectively replace the traditional measurement method of radar or ultrasound, ensuring that water depth data can be measured while effectively reducing production costs, facilitating promotion and application, and helping to improve the competitiveness of the product.

The scope of this utility model includes but is not limited to the specific embodiments described above. All equivalent changes made in accordance with this utility model are within the protection scope of this utility model.
