Description

Technical Field

[0001] This utility model relates to the field of water level measurement technology, and in particular to a water level indicator. Background Technology

[0002] A water level gauge is a tool used to measure water levels in real time in bodies of water such as rivers, lakes, reservoirs, and oceans. Based on an intuitive scale measurement method, it involves setting up a precisely graduated gauge at the edge of the water body or on a fixed structure, and then manually reading the water level. This provides crucial data for hydrological observation, flood warning, and water conservancy project scheduling.

[0003] Currently, water level markers typically require fixing the lower mounting plate to the underwater surface during installation. However, in practice, the unevenness of the underwater surface is difficult to guarantee, often resulting in the fixed mounting plate being tilted, causing the water level marker to also tilt and affecting the water level measurement results.

An adjusting component for adjusting the angle between the movable column and the beam seat is connected inside the beam seat. A fixing plate is fixedly connected to the side of the movable column away from the telescopic column via a transverse connecting rod. The movable column and the transverse connecting rod are arranged perpendicularly. The fixing plate and the movable column are arranged parallel to each other.

The upper half of the short column is a threaded part, and a fixing nut for limiting the rotation of the fixing seat is threaded on the outside.

[0010] Optionally, the crossbeam seat is fixedly connected to the lower surface of the sub-crossbeam, the upper end of the movable column is fixedly connected to an ear plate, and an ear seat is rotatably connected to the outer side of the ear plate, the ear seat being fixedly connected to the lower surface of the crossbeam seat.

[0011] Optionally, the crossbeam seat has an internal movable groove extending through its bottom. Symmetrical sliding grooves are formed on both sides of the movable groove. A guide groove extending through the sidewall of the crossbeam seat is formed on the side of the sliding groove away from the movable groove. The adjusting assembly includes a diagonal brace and a movable block. The diagonal brace is hinged to the lower end of the movable column on the side away from the transverse connecting rod. A second lug is hinged to the end of the diagonal brace away from the movable column. The movable block is fixedly connected to the upper end of the second lug. The movable block is slidably connected inside the movable groove. Sliding blocks are symmetrically fixed on both sides of the movable block. The sliding blocks are slidably connected inside the corresponding sliding groove. A threaded column is fixedly connected to the side of the sliding block away from the movable block.

[0015] The beneficial effects of this utility model through the above solution are as follows:

[0016] In this invention, if the telescopic column is tilted during installation, the verticality of the marker pole can be adjusted without adjusting the column itself, ensuring the marker pole remains relatively perpendicular to the water surface and thus improving measurement accuracy. Specifically, the operator first rotates the telescopic beam to the side of the tilting direction of the telescopic column or the opposite side. Then, by adjusting the components and using a level, the angle between the movable column and the beam seat is flexibly adjusted, ensuring the adjusted movable column is relatively perpendicular to the water surface, thereby indirectly ensuring the installed marker pole is also vertical.

[0026] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0027] Please see Figure 1-7 This utility model provides a water level indicator, including an indicator body 1 and a fixing bracket for fixing the indicator body 1. A base plate 11 is fixedly connected to the lower end of the indicator body 1. When installing the indicator body 1, it is necessary to ensure that the base plate 11 is in contact with the bottom surface. Secondly, the design of the base plate 11 increases the contact area. When the bottom surface is relatively soft or contains a lot of mud and sand, the increased contact area of ​​the base plate 11 can effectively prevent the indicator body 1 from being directly inserted into the bottom, thereby reducing the measurement error caused by the indicator body 1 sinking too deep.

[0028] The outer side of the marker body 1 is engraved with water level markings. After the marker body 1 is installed, the current water level can be visually determined by observing the water level markings on the outer side of the marker body 1. Secondly, a vertically sliding float can be installed on the outer side of the marker body 1. The float floats on the water surface, and its movement changes with the rise and fall of the water level. The relative position of the float on the outer side of the marker body 1 indicates the current water level (it should be noted that this water level monitoring method based on the relative position of the float is a conventional technical solution in this field, and its specific structure and working principle have been well-established and will not be elaborated upon here).

[0029] The fixed support includes a telescopic column 2, a telescopic crossbeam 3, and a movable column 5. One end of the telescopic crossbeam 3 is rotatably connected to the top of the telescopic column 2, and the two are perpendicular to each other. A crossbeam seat 4 is connected to the lower surface of the telescopic crossbeam 3. The movable column 5 is hinged to the lower surface of the end of the crossbeam seat 4 away from the telescopic column 2. An adjustment component 6 for adjusting the angle between the movable column 5 and the crossbeam seat 4 is connected inside the crossbeam seat 4. A fixing plate 8 is fixedly connected to the side of the movable column 5 away from the telescopic column 2 through a transverse connecting rod 51. The movable column 5 and the transverse connecting rod 51 are arranged perpendicularly, and the fixing plate 8 and the movable column 5 are arranged parallel to each other. A level 7 is fixedly installed on the transverse connecting rod 51. A fixing tube buckle 9 for fixing the marker body 1 is detachably installed on the side of the fixing plate 8 away from the transverse connecting rod 51.

[0030] Operators can flexibly adjust the actual height of the telescopic column 2 according to the actual water level, thereby fixing the body 1 of different lengths of the marker, and thus realizing water level measurement at different water depths, improving practicality.

[0031] When the telescopic column 2 is relatively perpendicular to the water surface, the water level measurement position of the marker body 1 can be flexibly adjusted by rotating the telescopic beam 3. Specifically, the telescopic beam 3 and the telescopic column 2 are in a rotating state. After the telescopic column 2 is fixed, the operator can select a suitable position within a circle with the length of the telescopic beam 3 as the radius, centered on the telescopic column 2, to measure the water level. Furthermore, by adjusting the length of the telescopic beam 3, the measurement radius can be changed, thereby covering a larger measurement area.

[0032] Working Principle: Before installation, the telescopic column 2 and the movable column 5 are relatively parallel. After the operator fixes the telescopic column 2 to the underwater surface, the operator can visually determine whether the movable column 5 or the telescopic column 2 is vertical or tilted using the level 7 on the horizontal connecting rod 51. If the movable column 5 or the telescopic column 2 is tilted, the operator can rotate the telescopic beam 3 to the side of the tilt direction of the telescopic column 2 or the opposite side. Then, the angle between the movable column 5 and the beam seat 4 is adjusted using the adjusting component 6 until the movable column 5 is adjusted to be relatively perpendicular to the water surface. Throughout the adjustment process, the operator can adjust the position by observing the level indication on the level 7. After adjustment, the fixing plate 8 will also remain perpendicular to the water surface. Finally, the marker body 1 is fixed to one side of the fixing plate 8 using the fixing tube buckle 9.

[0033] It should be noted that the level 7 can be a bubble level or other device that can be used for level calibration.

[0034] Furthermore, the telescopic column 2 includes a hollow main column 21 and a secondary column 22. The secondary column 22 is slidably connected to the upper part of the main column 21 and the two are fixed together by fixing bolts 23. The lower end of the main column 21 is fixedly connected to an installation plate 24. The installation plate 24 is fixedly connected to the underwater ground by ground nails. The upper end of the main column 21 has symmetrical threaded holes 211 on both sides. The outer wall of the secondary column 22 has multiple sets of longitudinally equidistant positioning holes 221 on both sides. The fixing bolts 23 are threaded through the threaded holes 211 and abut against the corresponding positioning holes 221. The outer wall of the secondary column 22 has multiple sets of longitudinally equidistant positioning lines 222. When the positioning lines 222 are level with the upper end of the main column 21, the threaded holes 211 are aligned with the corresponding positioning holes 221.

[0035] Specifically, when adjusting the overall height of the telescopic column 2, simply loosen the fixing bolt 23 so that its end disengages from the positioning hole 221. At this point, the auxiliary column 22 can slide up and down relative to the main column 21. Then, the operator can adjust the extension length of the auxiliary column 22 relative to the main column 21 according to the required height. During the adjustment process, the operator can visually determine whether the positioning hole 221 and the threaded hole 211 are aligned through the positioning line 222, greatly improving positioning efficiency. After adjustment, tighten the fixing bolt 23 again so that its end abuts against the corresponding positioning hole 221.

[0036] Furthermore, the telescopic beam 3 includes a main beam 31 and a secondary beam 32. The secondary beam 32 is slidably sleeved on the outer side of the right end of the main beam 31 and the two are fixed together by a locking bolt 33.

[0037] Specifically, when adjusting the overall length of the telescopic crossbeam 3, simply loosen the locking bolt 33. At this time, the secondary crossbeam 32 can slide left and right relative to the main crossbeam 31. After adjustment, tighten the locking bolt 33 so that its end abuts against the surface of the main crossbeam 31.

[0038] Furthermore, a fixing seat 311 is fixedly connected to one end of the main crossbeam 31 near the secondary column 22, and a short column 223 is fixedly connected to the center of the top of the secondary column 22. The lower half of the short column 223 is a smooth part, and the fixing seat 311 is rotatably sleeved on the outside of the smooth part of the short column 223. The upper half of the short column 223 is a threaded part, and a fixing nut 224 for limiting the rotation of the fixing seat 311 is threaded on the outside.

[0039] Specifically, the main crossbeam 31 can rotate freely around the short column 223 via the fixed seat 311, thereby achieving angle adjustment. After the rotation position is adjusted, the fixing nut 224 is tightened so that its lower surface abuts against the upper surface of the fixed seat 311, at which point the fixed seat 311 will be unable to rotate.

[0040] Furthermore, the crossbeam seat 4 is fixedly connected to the lower surface of the secondary crossbeam 32, and the upper end of the movable column 5 is fixedly connected to the ear plate 52. The outer side of the ear plate 52 is rotatably connected to the ear seat 53, and the ear seat 53 is fixedly connected to the lower surface of the crossbeam seat 4.

[0041] Specifically, the movable column 5 and the crossbeam seat 4 are in a hinged state. The upper end of the movable column 5 can rotate around the hinge point between the ear plate 52 and the ear seat 53 to adapt to different adjustment needs.

[0042] Furthermore, the interior of the crossbeam seat 4 is provided with a movable groove 41 that runs through its bottom. Sliding grooves 42 are symmetrically provided on both sides of the movable groove 41. A guide groove 43 that runs through the side wall of the crossbeam seat 4 is provided on the side of the sliding groove 42 away from the movable groove 41. The adjusting assembly 6 includes a diagonal brace 61 and a movable block 63. The diagonal brace 61 is hinged to the lower end of the movable column 5 on the side away from the transverse connecting rod 51. A second ear seat 62 is hinged to the end of the diagonal brace 61 away from the movable column 5. The movable block 63 is fixedly connected to the upper end of the second ear seat 62. The movable block 63 is slidably connected inside the movable groove 41. Sliding blocks 65 are symmetrically fixed on both sides of the movable block 63. The sliding blocks 65 are slidably connected inside the corresponding sliding groove 42. A threaded post 66 is fixedly connected to the side of the sliding block 65 away from the movable block 63. The threaded post 66 is slidably connected inside the corresponding guide groove 43. A limiting nut 67 for restricting the movement of the movable block 63 is threaded onto the outer side of the threaded post 66.

[0043] Specifically, when it is necessary to adjust the angle between the movable column 5 and the crossbeam seat 4, the movable block 63 is moved within the movable groove 41. Since the movable column 5, the diagonal brace 61, and a portion of the effective length of the crossbeam seat 4 form a triangular structure and are hinged together, moving the movable block 63 within the movable groove 41 changes a portion of the effective length of the crossbeam seat 4, thus altering the angle between the movable column 5 and the crossbeam seat 4. During the movement of the movable block 63, it drives the sliders 65 on both sides to slide within the corresponding grooves 42, which position and guide the sliders 65. After the position of the movable block 63 is adjusted, the limiting nut 67 on the outside of the threaded column 66 is tightened, causing the limiting nut 67 to abut against the side wall of the crossbeam seat 4. At this point, the position of the movable block 63 is fixed, indirectly fixing the angle between the movable column 5 and the crossbeam seat 4.

[0044] Furthermore, side plates 44 are fixedly connected to both ends of the crossbeam seat 4, and a lead screw 64 is rotatably connected between the two sets of side plates 44. The movable block 63 is threaded on the outside of the lead screw 64, and one end of the lead screw 64 passes through the corresponding side plate 44 and is fixedly connected to a knob 641.

[0045] Specifically, by rotating the lead screw 64 through the knob 641, the movable block 63 can be moved within the movable groove 41.

[0046] Furthermore, the surface of the fixing plate 8 is provided with multiple sets of fixing holes 81. The fixing tube buckle 9 includes a main arc buckle 91 and a secondary arc buckle 92. The main arc buckle 91 and the secondary arc buckle 92 are interlocked and fixed together by bolts, which are bolts and nuts. Two sets of threaded rods 93 are fixedly connected to the side of the main arc buckle 91 near the fixing plate 8. The threaded rods 93 pass through the fixing holes 81 at the corresponding positions and are fixed by the main nut 94.

[0047] Specifically, the fixing tube buckle 9 and the fixing plate 8 are detachable, and a suitable fixing tube buckle 9 can be selected for fixing according to the thickness of the marker body 1. When installing the fixing tube buckle 9, simply pass the threaded rod 93 through the corresponding fixing hole 81, and then thread the main nut 94 onto the outside of the threaded rod 93 to fix the threaded rod 93 to the fixing plate 8. When installing the marker body 1, simply place the marker body 1 on one side of the main arc buckle 91, and then fasten the secondary arc buckle 92 on one side of the main arc buckle 91. At this time, the marker body 1 is located inside the main arc buckle 91 and the secondary arc buckle 92, and finally fix it with bolts.

[0048] The above are merely preferred embodiments of this utility model and are not intended to limit this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
