Description

Technical Field

[0001] The utility model relates to the technical field of water depth measuring devices, and more specifically, to a water depth measuring device. Background Art

[0002] There are some key limitations in the existing resistive water depth measurement technology, which affect the accuracy of the measurement and the applicability of the equipment. First, the existing resistive water depth measurement device is difficult to maintain effective parallelism with the water surface during the measurement process, which leads to deviations in the measurement results.

[0003] First of all, the measurement principle of the resistance-type water depth measuring device depends on the parallelism between the device and the water surface. However, in practical applications, it is difficult to ensure that the device is always parallel to the water surface due to factors such as the installation method of the device, the influence of water flow, and the movement of the hull. This non-parallelism will cause errors in the measurement of the resistance value, which in turn affects the accuracy of the water depth data. Existing equipment often lacks an effective adjustment mechanism, making it difficult for operators to keep the device parallel to the water surface under complex hydrological conditions, thereby limiting the reliability and wide applicability of the measurement.

[0004] Secondly, the terrain and material of the bottom of the water are different, requiring the use of different shapes and sizes of the contact plate to adapt to different measurement environments. However, the existing resistance type water depth measurement device has the inconvenience of replacing the contact plate.

[0005] The diversity of underwater terrain requires that the measuring device can quickly adapt to different measuring conditions, which requires frequent replacement of the friction disc to optimize the measurement effect. However, existing equipment is often complex in design, and the process of replacing the friction disc is cumbersome and requires professional knowledge and tools, which not only increases the difficulty of operation, but also prolongs the replacement time and reduces work efficiency. In addition, the frequent replacement process may affect the stability and durability of the device, further increasing maintenance costs and equipment failure rates. Utility Model Content

[0017] (III) Beneficial effects

[0018] Compared with the prior art, the utility model provides a water depth measuring device, which has the following beneficial effects:

[0019] 1. The design of the detection mechanism enables the water depth measuring device to accurately measure the water level and maintain effective parallelism with the water surface. Through the cooperation of the outer sleeve, internal mechanism, sliding sleeve, expansion spring, horizontal plate, air bag, fixed sleeve, clamping mechanism, insertion rod and contact plate, the detection mechanism can measure the water level by the change of resistance value at different immersion positions. The coaxial setting of the outer sleeve and the inner sleeve, as well as the design of the sliding sleeve and the vertical groove, ensure the smooth flow of water, and the role of the air bag ensures the straightening of the sliding sleeve, thereby ensuring the verticality of the outer sleeve. This design improves the accuracy of measurement and adapts to the measurement needs under different hydrological conditions.

[0021] 3. The design of the clamping mechanism enables the water depth measuring device to easily replace the contact disc according to different bottom conditions. Through the cooperation of the contact ring, the insertion rod, the annular groove, the friction disc, the extension plate, the spring and the contact strip, the clamping mechanism can fix the insertion rod through the action of the fillet and the spring. In addition, by changing the position of the friction disc, the position between the spring and the contact strip can be adjusted, thereby changing the elastic force of the spring to adapt to the measurement requirements under different bottom conditions. This design simplifies the replacement process, improves the convenience of operation, and enhances the adaptability of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] In this embodiment, since the water level is measured by the difference in resistance values ​​at different immersed positions between the inner sleeve 10 and the outer sleeve 2 during use, the outer sleeve 2 needs to be vertical. Water can be passed into the outer sleeve 2 and the inner sleeve 10 through the through groove 11. Since the sliding sleeve 3 is slidably connected to the outer sleeve 2, the water flow can be guaranteed through the vertical groove 12. Then, the sliding sleeve 3 is straightened by the action of the airbag 6, thereby ensuring the verticality of the outer sleeve 2 and further ensuring the measurement effect.

[0033] See also Figures 3 to 5 As an implementation method of the clamping mechanism: the clamping mechanism includes a contact ring 13, a plurality of contact rings 13 are provided, and the plurality of contact rings 13 are respectively slidably connected to the fixed sleeve 7, an annular groove 14 is provided on the side wall of the insertion rod 8, and the plurality of contact rings 13 are respectively pressed in the annular groove 14, a rounded corner 15 is provided on the insertion rod 8, a friction disk 16 is slidably provided on the fixed sleeve 7, a plurality of protruding plates 17 are provided on the friction disk 16, a plurality of springs 18 are provided on each protruding plate 17, and bottom strips 19 are respectively provided on the lower end surfaces of the plurality of springs 18, a contact strip 20 is provided on the contact ring 13, and the contact strip 20 is in contact with the spring 18.

[0034] More specifically, when it is necessary to replace different resistance discs 9 according to different underwater conditions, first insert the corresponding insertion rod 8 into the fixing sleeve 7, and then push open the resistance ring 13 through the fillet 15. At this time, the resistance strip 20 fits on the spring 18, so the spring 18 will exert a moving elastic force, ensuring that the resistance ring 13 has a force toward the axis, and then when the resistance ring 13 is pressed against the annular groove 14, the fixation of the insertion rod 8 can be ensured, thereby completing the fixing process. When it is necessary to adjust the elastic force of the spring 18, it is only necessary to change the position of the friction disc 16 to change the position between the spring 18 and the resistance strip 20, thereby changing the elastic force. Therefore, the fixing force can be adjusted to adapt to the underwater conditions.

[0035] In summary, the overall device is in use or running: when in use, the water level is measured by the difference in resistance values ​​at different immersed positions between the inner sleeve 10 and the outer sleeve 2, so the outer sleeve 2 needs to be vertical, and water can be passed into the outer sleeve 2 and the inner sleeve 10 through the through groove 11. Since the sliding sleeve 3 is slidably connected to the outer sleeve 2, the water flow can be guaranteed through the vertical groove 12, and then the sliding sleeve 3 is straightened by the action of the airbag 6, thereby ensuring the verticality of the outer sleeve 2 and then ensuring the measurement effect.

[0036] When it is necessary to replace different resistance discs 9 according to different underwater conditions, first insert the corresponding insertion rod 8 into the fixing sleeve 7, and then push open the resistance ring 13 through the fillet 15. At this time, the resistance strip 20 fits on the spring 18, so the spring 18 will exert a moving elastic force, ensuring that the resistance ring 13 has a force toward the axis. Then, when the resistance ring 13 is pressed against the annular groove 14, the fixation of the insertion rod 8 can be ensured, thereby completing the fixing process. When it is necessary to adjust the elastic force of the spring 18, it is only necessary to change the position of the friction disc 16 to change the position between the spring 18 and the resistance strip 20, thereby changing the elastic force. Therefore, the fixing force can be adjusted to adapt to the underwater conditions.

[0037] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which are not described here one by one. In the above, all fixed connections are preferably welded.
