[0001] This disclosure relates to the field of engineering measurement technology, and in particular to a water level detection device. Background Technology

[0002] Construction quotas are one of the important bases for cost consulting work. Earthwork excavation and backfilling are important components of construction quotas issued by local government housing and urban-rural development authorities. Most construction quotas specify quotas for excavation of both dry and wet soil.

[0003] The chapter on earthwork engineering in the Comprehensive Quota for Housing Construction and Decoration Engineering in Guangdong Province stipulates the classification of dry soil and wet soil. First, it should be based on the geological survey data, with a moisture content of <25% being dry soil and a water content of ≥25% being wet soil; or it can be based on the groundwater level, with soil above the normal groundwater level being dry soil and soil below it being wet soil.

[0004] The classification of dry and wet soil is based on a stable groundwater level. The engineering cost is calculated using groundwater level detection devices. However, the existing water level detection devices are labor-intensive and the process of obtaining a stable groundwater level is complicated. Utility Model Content

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the embodiments of this disclosure will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the embodiments of this disclosure and are not intended to limit the embodiments of this disclosure.

[0035] like Figure 1 and Figure 3 As shown in the figure, this disclosure proposes a water level detection device, which includes: a measuring ruler 100 with a scale, wherein a water level sensor 110 is provided inside the measuring ruler 100; a leveling assembly 200 with an opening 211 through which the measuring ruler 100 is movably inserted, and the leveling assembly 200 is also provided with a spirit level to level the measuring ruler; and a straightener 300 with a through limiting groove 310 connected to the opening 211, wherein the straightener 300 is detachably disposed on the leveling assembly 200, and the limiting groove 310 can slidably pass through the measuring ruler 100 and fix the measuring ruler to straighten the measuring ruler.

[0036] The groundwater level measuring device of this disclosure is used for groundwater level detection in engineering cost estimation. A measuring ruler is fixed to an operating platform with a level, i.e., a leveling assembly. The leveling assembly has an opening for the measuring ruler to move up and down. The opening is relatively large, and the measuring ruler may shift, requiring a straightener for further straightening. The straightener's limiting groove matches the size of the measuring ruler to achieve this purpose. The straightener is detachably mounted on the leveling assembly, facilitating the disassembly, assembly, and transport of the groundwater level detection device.

[0037] The measuring ruler is equipped with a water level sensor. A stable reading from the sensor indicates that the measuring ruler has detected a stable groundwater level, which helps in obtaining an accurate water level. In practice, multiple measurements are needed to obtain an accurate groundwater level. The purpose of the detection device in this embodiment is to fix the measuring ruler and take readings at different times. Once the readings stabilize, a stable groundwater level can be obtained.

[0038] like Figure 2 As shown, the indicator 110 includes an indicator light; a wire 120 and a power supply 130 are provided inside the measuring ruler 100, the power supply 130 and the indicator light are connected in series in the wire 120, and both ends of the wire 120 are exposed at one end of the measuring ruler 100 that measures the water level; the indicator light is located at the other end of the measuring ruler 100.

[0039] In other words, both ends of the wire protrude from the end of the measuring ruler that measures the water level. Specifically, both ends of the wire protrude from the bottom of the measuring ruler, and the indicator light is located at the top of the measuring ruler. The measuring ruler is equipped with insulated conductive wires. When the bottom of the measuring ruler contacts the water body, both wires simultaneously contact the groundwater. The groundwater conducts electricity, causing the wires, groundwater, battery, and light bulb to form a closed loop, which drives the light bulb to light up. This process is repeated several times until the reading stabilizes.

[0040] like Figure 3 As shown, the leveling assembly 200 includes: a leveling plate 210, with threaded holes (not shown) at each of its four corners; and bolt feet 270, the threads of which are threaded into the threaded holes (not shown) to level the leveling plate. Alternatively, as... Figure 1 As shown, the adjusting plate 210 has through holes (not shown in the figure) at its four corners; a screw 220, one end of which is provided with a pad 230, and the other end of which passes through the through hole, with an elastic element 250 abutting between the pad 230 and the adjusting plate 210; and a nut 240, which can be threaded to the other end of the screw 220.

[0041] The adjusting plate of this embodiment is provided with a level 260, such as a long level or a circular level; for example... Figure 1As shown, the elastic element can be a spring, which is sleeved on the screw, with its two ends abutting against the pad and the adjusting plate, respectively. The adjusting plate can be leveled by rotating the nuts according to a long or circular level. Figure 3 As shown, the leveling plate can be leveled by turning the bolt feet.

[0042] like Figure 4 As shown, the opening 211 is provided on the adjusting plate 210, and fixing grooves 212 are respectively provided around the opening 211; as Figure 5 As shown, the centering device 300 has insert blocks 320 around its side limiting groove 310 that cooperate with the fixing groove 212.

[0043] The straightener in this embodiment can be a cubic structure. The insert of the straightener is interference-fitted with the corresponding fixing groove. The fixing groove can also be provided with a protrusion. The insert can be inserted into the fixing groove to fix the straightener.

[0044] The limiting groove matches the size of the measuring ruler and is slightly larger than the size of the measuring ruler, thus limiting the measuring ruler and ensuring that the measuring ruler does not deviate in the vertical direction.

[0045] like Figure 6 As shown, the stabilizer 300 has a through hole on the side away from the scale of the measuring ruler 100. A fastening screw 330 is provided in the through hole. The fastening screw 330 passes through the stabilizer 300, and one end of it abuts against the measuring ruler 100.

[0046] In this embodiment, the measuring scale is inserted into the limiting groove of the stabilizer and can be tightened with a fastening screw, so that one end of the fastening screw abuts against the measuring scale. A rubber buffer pad or similar material can be provided at one end of the fastening screw to increase the friction at the contact point. When taking the reading, the water level can be obtained by subtracting the thickness of the stabilizer from the junction of the upper surface of the stabilizer and the measuring scale.

[0047] like Figure 1 and Figure 7 As shown, a transparent observation window 350 is provided on the side of the stabilizer opposite to the through hole. The reading of the measuring scale can be read through the observation window. The materials of the stabilizer and the observation window can be set according to the actual situation.

[0048] When measuring groundwater level in engineering, first install the stabilizer on the leveling plate, place the leveling plate on the support platform above the groundwater level to be measured, and roughly level the leveling plate; then, vertically insert the measuring ruler through the stabilizer and the leveling plate, tighten the fixing screw so that one end abuts against the measuring ruler, and fix the measuring ruler; then fine-tune the leveling plate again; then, loosen the fixing screw, slowly slide the measuring ruler down, and observe the indication of the indicator. If the light bulb lights up and stabilizes, a stable water level is detected. Read the reading of the measuring ruler, repeat the measurement at intervals, and when the measurement data stabilizes, a stable groundwater level is obtained.

[0049] like Figure 1 and Figure 7 As shown, a blocking block 140 is provided at the other end of the measuring ruler 100.

[0050] That is, a blocking block is set at the top of the measuring ruler to prevent the measuring ruler from falling off the opening and the limiting groove.

[0051] like Figure 7 As shown, the straightener 300 can extend and retract along the length of the measuring ruler 100.

[0052] When the stabilizer is in the extended state, it provides better limiting and stabilizing effect on the measuring scale.

[0053] The above description is only a preferred embodiment of the present disclosure. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present disclosure, and these improvements and modifications should also be considered within the protection scope of the present disclosure.
