Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of depth measuring instruments; more specifically, it relates to a depth measuring instrument. Background Technology
[0002] A depth gauge is a device used to measure the depth of water bodies. It is widely used in various fields. In meteorology, it can infer the regional precipitation intensity by measuring the changes in the depth of lakes and reservoirs, and help verify the accuracy of rainfall estimation by weather radar. At the same time, water depth data can reveal changes in water evaporation, reflect the dry and wet trends of the climate, and provide hydrological evidence for climate change research.
[0003] Currently, existing depth measuring instruments have several drawbacks. Firstly, they typically require manual handling, which can increase the workload for operators over extended periods. Secondly, their instability can affect measurement results, reducing their practicality. Thirdly, existing instruments generally use a rope method, requiring operators to hold a rope and a weight, place the weight in the water, and observe the markings on the rope to determine the depth. However, this method has a limited measurement range and requires operators to be near the measurement area, potentially posing safety hazards and further reducing the instrument's usability. Therefore, a new depth measuring instrument is urgently needed to address these issues. Utility Model Content
[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a water depth measuring instrument to solve the problems existing in the background art.
[0005] This utility model provides the following technical solution: a water depth measuring instrument, comprising:
[0006] The main cylinder has a positioning structure on its lower outer surface and an adjustment structure inside.
[0007] The positioning structure includes a connecting plate, and the connecting plate is hinged to the outer surface of one end of the lower part of the main cylinder;
[0008] The adjustment structure includes a first sleeve rod, which is fixedly connected to the inside of the main cylinder.
[0009] Preferably, the positioning structure further includes a support plate, which is hinged to the outer surface of the lower end of the connecting plate. A ground nail is threadedly connected to the inner surface of the outer surface at the middle position of the support plate. A connecting block is hingedly connected to the outer surface of the other end of the lower end of the main cylinder. A first bolt is threadedly connected to the inner surface of the outer surface of the upper side of the connecting block. A hinge rod is hingedly connected to the outer surfaces of both sides of the lower end of the connecting block. A second bolt is hingedly connected to the inner surface of the outer surfaces of both sides of the lower end of the connecting block. This design allows the support plate to be positioned by rotating the ground nail downwards into the ground.
[0010] Preferably, the lower end of the ground nail is conical in shape. The outer surface of one inner end of the first bolt is attached to the outer surface of the main cylinder at the hinge connection between the main cylinder and the connecting block. The outer surface of one inner end of the second bolt is attached to the outer surface of the hinge rod at the hinge connection between the hinge rod and the connecting block. This design, by pressing the first bolt against the outer surface of the main cylinder, can position the connecting block.
[0011] Preferably, the adjustment structure further includes a second sleeve rod, which is inserted inside the first sleeve rod, and a third sleeve rod is inserted inside the second sleeve rod. A guide ring is fixedly connected to the outer surface of the upper end of each of the first, second, and third sleeve rods. A wire frame is fixedly connected to the outer surface of the upper end of the main cylinder, and a spool is connected to the internal bearing of the wire frame. A crank handle is fixedly connected to the outer surface of one end of the spool. A measuring line is sleeved on the outer surface of the spool, and a depth measuring plumb line is fixedly connected to one end of the measuring line. This design allows the spool to rotate by rotating the crank handle.
[0012] Preferably, the outer surface of one end of the second and third sleeve rods is provided with a limiting ring, and the outer dimensions of the limiting rings are adapted to the inner dimensions of the first and second sleeve rods, respectively. The outer surfaces of both ends of the wire frame are provided with rotating grooves, and the outer surfaces of both ends of the spool are provided with rotating rings, and the inner dimensions of the rotating grooves are adapted to the outer dimensions of the rotating rings. This design allows the second and third sleeve rods to move inside the first and second sleeve rods, respectively, and the second and third sleeve rods will not detach from the inside of the first and second sleeve rods.
[0013] Preferably, the outer surface of the measuring line is marked with graduations, and the sounding plumb line is designed in a conical shape, which helps staff to have a more intuitive observation of the water depth.
[0014] The technical effects and advantages of this utility model are as follows: This utility model uses a downward hinged rotating connecting block and hinged rotating connecting rods to both sides. After adjusting to a suitable direction, the first bolt and the second bolt are rotated to tighten the main cylinder and the hinge rod respectively, which can position the connecting block and the hinge rod. The downward hinged rotating connecting plate and the support plate make the support plate fit against the ground. The downward threaded rotation of the ground nail makes it penetrate into the ground, which can position the support plate. In this way, the equipment can be positioned more stably on the ground, avoiding the situation where the handheld equipment is not stable enough and affects the measurement results, thus improving the practicality of the equipment to a certain extent.
[0015] By moving the second and third rods inside the first and second rod sets, the measurable distance of the device can be adjusted. Rotating the crank handle drives the spool to rotate, which allows the measuring line on the outer surface of the spool to be extended or retracted. The position of the depth measuring rod in the water can be adjusted, and the water depth can be observed by looking at the scale on the outer surface of the measuring line. This allows water depth to be measured without being near the water depth measurement area, which improves the practicality of the device to a certain extent. Moreover, its overall structure is simple and reasonable in design, highly practical, and easy to promote and apply. Attached Figure Description

[0023] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The water depth measuring instrument involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0024] Example 1
[0025] like Figures 1-3 As shown, this embodiment proposes a water depth measuring instrument, including:
[0026] The main cylinder 1 has a positioning structure 2 on its lower outer surface and an adjustment structure 3 inside.
[0027] The positioning structure 2 includes a connecting plate 21, which is hinged to the outer surface of one lower end of the main cylinder 1. The positioning structure 2 also includes a support plate 22, which is hinged to the outer surface of the lower end of the connecting plate 21. A ground nail 23 is connected to the inner thread of the outer surface of the middle position of the support plate 22. A connecting block 24 is hinged to the outer surface of the other lower end of the main cylinder 1. A first bolt 25 is connected to the inner thread of the outer surface of one upper side of the connecting block 24. A hinge rod 26 is hinged to the outer surfaces of both lower sides of the connecting block 24. A second bolt 27 is hinged to the inner thread of the outer surfaces of both lower sides of the connecting block 24. The lower end of the ground nail 23 is conical. The outer surface of one inner end of the first bolt 25 is attached to the outer surface of the main cylinder 1 at the hinged connection between the main cylinder 1 and the connecting block 24. The outer surface of one inner end of the second bolt 27 is attached to the outer surface of the hinge rod 26 at the hinged connection between the hinge rod 26 and the connecting block 24.
[0028] In this embodiment, the conical design of the ground nail 23 improves the efficiency of the ground nail 23 when it is driven into the ground, allowing the ground nail 23 to penetrate deeper into the ground and making the position of the support plate 22 more stable. By rotating the first bolt 25 inside the thread of the connecting block 24 to make it abut against the outer surface of the main cylinder 1, the position of the connecting block 24 relative to the main cylinder 1 can be positioned. By rotating the second bolt 27 inside the thread of the connecting block 24 to make it abut against the outer surface of the hinge rod 26, the position of the hinge rod 26 relative to the connecting block 24 can be positioned. With the support of the support plate 22 and the two sets of hinge rods 26, the position of the equipment can be positioned.
[0029] Example 2
[0030] like Figures 4-6 As shown, based on the same concept as the above embodiments, this embodiment also proposes:
[0031] The adjusting structure 3 includes a first sleeve rod 31, which is fixedly connected to the inside of the main cylinder 1. The adjusting structure 3 also includes a second sleeve rod 32, which is inserted into the first sleeve rod 31. A third sleeve rod 33 is inserted into the second sleeve rod 32. A guide ring 34 is fixedly connected to the outer surface of one end of each of the first, second, and third sleeve rods 33. A wire frame 35 is fixedly connected to the outer surface of one end of the main cylinder 1, and a spool 36 is connected to the internal bearing of the wire frame 35. A limiting ring is provided on the outer surface of one end of each of the second and third sleeve rods 33, and the external dimensions of the limiting rings are respectively related to the internal dimensions of the first and second sleeve rods 31 and 32. The inner surfaces of the outer surfaces at both ends of the wire frame 35 are provided with rotating grooves, and the outer surfaces at both ends of the spool 36 are provided with rotating rings. The inner dimensions of the rotating grooves are matched with the outer dimensions of the rotating rings. This design allows the second sleeve rod 32 and the third sleeve rod 33 to move inside the first sleeve rod 31 and the second sleeve rod 32 respectively. The movement of the second sleeve rod 32 and the third sleeve rod 33 is more stable, and the second sleeve rod 32 and the third sleeve rod 33 will not detach from the interior of the first sleeve rod 31 and the second sleeve rod 32. By rotating the crank handle 37, the spool 36 can be driven to rotate inside the wire frame 35. The rotation of the spool 36 is more stable, and the spool 36 will not detach from the interior of the wire frame 35.
[0032] Furthermore, a crank 37 is fixedly connected to the outer surface of one end of the spool 36, and a measuring line 38 is sleeved on the outer surface of the spool 36. One end of the measuring line 38 is fixedly connected to a sounding plumb line 39. The outer surface of the measuring line 38 is marked with a scale. The sounding plumb line 39 has a conical design. This design can more effectively maintain the center of gravity, making the measuring line 38 more stable when moving downward or upward. This can ensure the accuracy of the measurement data to a certain extent. At the same time, by observing the scale on the outer surface of the measuring line 38, the water depth can be observed more intuitively.
[0033] Working principle: When using the equipment, first, place the equipment in a suitable position according to the required water depth. Then, hinge the rotating connecting block 24 downwards and position it by rotating the first bolt 25. Next, hinge and rotate the two sets of hinge rods 26 to both sides. After adjusting to the appropriate direction, position the hinge rods 26 by rotating the second bolt 27. Then, hinge the rotating connecting plate 21 and the support plate 22 downwards so that the support plate 22 is in contact with the ground. Then, drive the ground nail 23 into the ground to position the support plate 22. This positions the equipment. Next, pull the third set of rods 33 and the second set of rods 32 outwards so that the position of the sounding plumb bob 39 is at the position where the water depth needs to be measured. At this time, rotate the crank handle 37 to drive the spool 36 to rotate, so that the measuring line 38 on the outer surface of the spool 36 can be released, allowing the sounding plumb bob 39 to slowly descend into the water. At this time, the water depth can be measured by observing the scale on the outer surface of the measuring line 38. The above is the complete working principle of this utility model.
[0034] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
