Description

Technical Field

[0001] The utility model relates to the technical field of hydrological gauges, in particular to an adjustable hydrological gauge. Background Art

[0002] A hydrographic ruler is a tool used to measure ground water level or depth, and is commonly used for the observation and monitoring of water bodies such as rivers, lakes or reservoirs. A hydrographic ruler is generally a graduated rod fixed vertically to the ground, with a series of equally spaced graduations engraved on the rod. The water level or depth can be determined by reading the graduations on the water surface or underwater.

[0003] In order to ensure long-term and stable use, the existing water level gauges are mostly of fixed length, and in order to ensure their measuring range, the water level gauges are large and bulky. However, in some places where water level changes need to be temporarily monitored, the water level gauge needs to be able to be quickly installed while facilitating the adjustment of the overall height of the hydrological gauge device. Existing water level gauges are difficult to meet these requirements.

[0004] Therefore, there is a need to design an adjustable hydrological gauge for use in temporary environments. Utility Model Content

[0005] In order to overcome the shortcomings of existing water level gauges that are difficult to meet the requirements in some places where temporary monitoring of water level changes is required, the water level gauge needs to be able to be quickly installed while facilitating the adjustment of the overall height of the hydrological gauge device. The technical problem is: to provide an adjustable hydrological gauge for temporary environments.

[0006] The technical solution is: an adjustable hydrological ruler, comprising: a first ruler and a slide groove, the first ruler has vertical slide grooves evenly opened on the circular arc surface; a first scale, the first ruler has a first scale opened on the surface between two slide grooves; a second ruler, the first ruler has a second scale slidably provided along the slide groove; a second scale, the second ruler has second scales alternately opened on two outer circular arc surfaces close to the first scale; a first ring, the first ring is fixedly provided on the outer surface of the lower end of the second ruler; a floating block, the first ring is fixedly provided with a floating block on the circular arc surface away from the first scale; a second ring, the second ring is fixedly provided on the outer surface of the upper end of the first ruler.

[0007] Furthermore, it also includes: a lifting thread, a lifting thread is opened on the outer surface of the arc at the lower end of the first ruler; a base and a sliding hole, a sliding hole of the same size as the projection of the bottom surface of the first ruler is opened at the center of the base, and the first ruler is slidably matched with the sliding hole; a sleeve block, a sliding hole is fixedly provided along the protruding outer edge of the sliding hole at the upper end of the base; a handwheel, a handwheel is rotatably provided in the sleeve block, a threaded hole is opened at the middle axis of the handwheel, and the threaded hole is matched with the lifting thread.

[0008] Furthermore, it also includes: through holes, which are vertically opened at the three corners of the base; anchor rods, which are slidably provided at the through holes of the base, and the upper ends of the anchor rods are threaded; adjusting nuts, an adjusting nut is provided on the upper and lower ends of the anchor rod, and the adjusting nut is threadedly matched with the anchor rod.

[0009] Furthermore, it also includes: an observation hole, and the front of the first ring is provided with an observation hole.

[0010] Furthermore, it also includes: a buzzer, which is fixedly provided at the uppermost end of the second scale; a switch, which is provided at the lower front end of the second ring; and a wire, which is connected between the buzzer and the switch.

[0011] The utility model has the following advantages: 1. In the utility model, the measuring range of the hydrological scale is expanded by the retractable second scale, the height of the second hydrological scale is controlled by the floating block, and the top of the first scale is set at the warning water level.

DETAILED DESCRIPTION

[0019] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0020] Example 1

[0021] like Figure 1-4 As shown, the utility model provides an adjustable hydrological ruler, which specifically includes: a first ruler 1, a first scale 3, a second ruler 4, a second scale 5, a first ring 6, a floating block 7 and a second ring 8;

[0022] The first scale 1 has vertical chute 2 evenly formed on its arc surface, a first scale 3 formed on the surface between two of the chute 2, a second scale 4 slidably disposed along the chute 2, and second scales 5 staggeredly formed on two outer arc surfaces of the second scale 4 near the first scale 3, for extending the water level monitoring range;

[0023] The lower outer surface of the second scale 4 is fixedly provided with a first ring 6 for accurately observing the specific scale of the water level;

[0024] Among them, a first ring 6 is fixedly provided with a floating block 7 on the arc surface away from the first scale 3, and a second ring 8 is fixedly provided on the outer surface of the upper end of the first scale 1 to drive the second scale 4 to rise as the water level changes.

[0025] In the utility model, the utility model has a self-adjusting function. When the water level at the set hydrological scale changes frequently, and the uppermost end of the first scale 1 is set as the warning water level, when the water level starts to rise from a lower safety water level, if the water level rises to less than or equal to the warning water level, the staff only needs to read the first scale 3 of the first scale 1 to meet the hydrological scale requirements. If the water level rises to greater than the warning water level, the floating block 7 rises with the rise of the water level, and the first ring 6 fixed thereto rises, and the second scale 4 fixed thereto rises along the slide groove 2 of the first scale 1, and the first ring 6 gradually approaches the second ring 8. When the two are in contact, due to the second ring 8 The ring 8 is fixed to the first scale 1, and the second ring 8 limits the rise of the first ring 6. Due to the buoyancy of the floating block 7 of the first ring 6, the second scale 4 is fixed to the upper end of the first scale 1, forming a hydrological scale with a longer measuring range. Since the first scale 3 cannot be read, the water level can be measured by reading the second scale 5. When the water level drops to a safe water level, the height of the second scale 4 decreases as the water level drops. At this time, the water level can be obtained by reading the first scale 1. Compared with a fixed long-pole water level scale, this scale can not only achieve the same measuring range, but is also less bulky and easier to install. It has the advantage of "one for two" over a water level scale of ordinary height.

[0026] Example 2

[0027] like Figure 3 and Figure 4 As shown, on the basis of Example 1, it specifically includes: a lifting thread 9, a base 10, a sleeve block 12 and a hand wheel 13. The lifting thread 9 is opened on the outer surface of the arc at the lower end of the first scale 1, and a sliding hole 11 with the same size as the bottom surface projection of the first scale 1 is opened at the center of the base 10. The first scale 1 is slidably matched with the sliding hole 11. The upper end of the base 10 is fixedly provided with the sliding hole 11 along the protruding outer edge of the sliding hole 11. A hand wheel 13 is rotatably provided in the sleeve block 12. A threaded hole is opened at the middle axis of the hand wheel 13, and the threaded hole is matched with the lifting thread 9.

[0028] After installing the water level gauge, the staff can turn the hand wheel 13 to control the rotation of the inner thread of the hand wheel 13 and the moving up and down of the lifting thread 9 matched therewith. In this way, when the staff finds that there is an error in the scale height of the water level gauge after installing the water level gauge, they can adjust the movement of the first scale 1 by turning the hand wheel 13 to make the first scale 3 of the first scale 1 reach the correct height. In addition, since there is a self-locking function between the threads, there is no need to worry about the subsequent deviation of the scale height.

[0029] like Figure 1 and Figure 4 As shown, on the basis of Example 1, it specifically also includes: an anchor rod 15 and an adjusting nut 16, through holes 14 are vertically opened at the three corners of the base 10, and the anchor rod 15 is slidably provided at the through hole 14 of the base 10. The upper end of the anchor rod 15 is threaded, and an adjusting nut 16 is respectively provided on the upper and lower ends of the anchor rod 15, and the adjusting nut 16 is threadedly matched with the anchor rod 15.

[0030] Before installing the water level gauge, the staff should nail the anchor rod 15 with the threaded end facing upwards, and put an adjusting nut 16 on each. Then, the base 10 and the anchor rod 15 should be placed according to the position of the through hole 14. The base 10 and the anchor rod 15 should be slidably matched and seated on the adjusting nut 16. The staff can adjust the inclined position of the base 10 by adjusting the adjusting nut 16 under the through hole 14 to ensure the verticality of the first scale 1 and the second scale 4 on the base 10. After adjusting the verticality, add adjusting nuts 16 on the anchor rod 15, that is, above the base 10, to fix the base 10. In this way, the verticality of the hydrological gauge can be adjusted after installation to make the measurement accuracy of the hydrological gauge higher.

[0031] like Figure 2 As shown, based on the embodiment 1, it further includes: an observation hole 17, and an observation hole 17 is opened in the front of the first ring 6.

[0032] When the water level is at a safe level, the water has not yet submerged the first ruler 1, and the observation hole 17 is opened in the first ring 6 near the first scale 3. Since the first ring 6 is fixedly matched with the floating block 7, the observation hole 17 can be flush with the water surface by setting the buoyancy of the floating block 7. At the same time, since there is a pointed protrusion next to the observation hole 17, the staff can rely on the pointed protrusion to read more accurately when reading the number through the observation hole 17.

[0033] like Figure 1 and Figure 3 As shown, based on Example 1, it specifically also includes: a buzzer 18, a buzzer 18 is fixedly provided at the uppermost end of the second scale 4; a switch 19, a switch 19 is provided at the lower front end of the second ring 8; a wire 20, a wire 20 is connected between the buzzer 18 and the switch 19.

[0034] When the water level exceeds the warning water level, the first ring 6 contacts the second ring 8, and the switch 19 located on the second ring 8 contacts the first ring 6 to trigger the switch 19, which sends a signal to the buzzer 18 at the top of the second scale 4 through the wire 20 connected thereto, causing the buzzer 18 to sound an alarm. In this way, when the staff cannot observe the water level in real time for some reason, the staff can quickly know that the water level exceeds the warning water level through the alarm sound of the buzzer 18.

[0035] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
