Description

Technical Field

[0001] The invention relates to the technical field of liquid tank depth measurement for ships and offshore platforms, and in particular to a real-time measurement depth gauge. Background Art

[0002] Ships and offshore platforms generally require the use of multiple tanks. In order to conduct tilt tests and calibrate tank level sensors and other processes, the liquid level height of the tank needs to be measured. The measuring tool used in the prior art is a manual depth gauge, including a tape measure with a handle, and a small weight is connected to the end of the tape measure. During measurement, the small weight is acted upon by gravity, driving the tape measure down along the depth tube to the bottom of the cabin, and then the depth value is obtained by observing the reading of the depth tube by recovering the lifting distance of the tape measure. This measurement method requires wiping the liquid marks on the tape measure before the next measurement. If the tank is loaded with a color-developing liquid such as fuel oil, the liquid level depth is determined and recorded by the marks on the tape measure; if the tank is loaded with a transparent liquid such as fresh water, the approximate water depth is determined by the water marks, and then the relevant chemicals that change color when exposed to water are applied for a second measurement, and the liquid level depth is determined and recorded by the marks on the tape measure.

[0003] The measurement methods in the prior art have the following disadvantages:

[0004] 1. There are many measurement steps and the measurement time is long. For example, when measuring a water tank, it is necessary to go through the steps of lowering the ruler, retracting the ruler, wiping, applying chemicals, and measuring again. When measuring an oil tank, it is troublesome to wipe off the oil stains on the measuring tape, and the deeper the liquid level, the longer it takes.

[0005] 2. Measurement is prone to oil stains. Every time the whole ship is measured, the oil and water tanks need to be measured, and a rag is needed to wipe them. During the measurement process, the body and clothes are easily stained with oil.

[0006] 3. The life of the tape measure is short. After multiple measurements, the oil stains on the tape measure are difficult to clean and the scale becomes blurred, affecting its use.

[0007] 4. Poor measurement accuracy. After the small weight hits the bottom of the bilge, the measuring tape may bend slightly, causing the oil and water marks to be higher than the actual water depth, and the top of the oil and water marks to be blurred, resulting in obvious inaccuracy in the height reading.

[0008] 5. It cannot measure in real time. When the tilt test uses ballast water to adjust the tilt angle of the ship, it is often the case that too much or too little ballast water is adjusted, and the pump needs to be turned on and off many times, which is time-consuming and labor-intensive. Summary of the invention

DETAILED DESCRIPTION

[0032] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

It should be understood that the terms "first", "second", etc. are used in the present invention to describe various information, but such information should not be limited to these terms, which are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present invention, the "first" information may also be referred to as the "second" information, and similarly, the "second" information may also be referred to as the "first" information.

[0034] The preferred embodiment of the real-time depth measuring ruler of the present invention is specifically referred to Figures 1 to 4As shown, it includes a shell 1 and a floating block 2 arranged at the lower part of the shell 1. The shell 1 can be made of transparent material. The upper part of the shell 1 is provided with a left tape measure structure 3 and a right tape measure structure 4 in rows and intervals. The left tape measure structure 3 is provided with a left tape measure 31, and the right tape measure structure 4 is provided with a right tape measure 41. The left tape measure structure 3 and the right tape measure structure 4 are relatively and independently arranged. A left handle 5 for driving the left tape measure structure 3 to rotate to retract the left tape measure 31 is provided on the left side of the shell 1, and a right handle 6 for driving the right tape measure structure 4 to rotate to retract the right tape measure 41 is provided on the right side of the shell 1. The left handle 5 and the right handle 6 both extend to the outside of the shell 1 for easy manual operation; the free end of the left tape measure 31 is connected to the free end of the right tape measure 41 to form a tape measure ring, so that when the left tape measure structure 3 or the right tape measure structure 4 is rotated, the tape measure ring can be driven to increase or decrease, and a rolling member 7 for the tape measure ring to pass through is provided on the upper part of the floating block 2. The housing 1 is used to protect the internal structure from being damaged or contaminated by external forces. When measuring, it can be placed on the plane of the top of the sounding tube 9 and fixed to it. Turning the left handle 31 or the right handle 41 can drive the tape ring to drive the float 2 to move downward. When the float 2 moves down to the liquid level of the liquid tank and is suspended, the liquid level value of the liquid tank can be calculated.

[0035] The real-time measurement depth gauge of the present invention has few measurement steps and short time consumption. The left handle 31 and the right handle 41 are driven to drive the floating block 2 to move so as to perform real-time measurement. The whole process only needs three steps of releasing the ruler, reading and retracting the ruler. Moreover, the higher the liquid level in the liquid tank, the shorter the distance of releasing the ruler and the shorter the time consumption. The tape measure is not easy to be stained with oil and the depth gauge has a long service life. Even after multiple measurements, the depth gauge will not be stained with oil to affect its use, and at the same time, it can avoid the adhesion of oil to hands, clothes and the like. The measurement accuracy is high, and the problem of the original tape measure scale being blurred is avoided. With the plane and density calibration of the shell 1, the liquid surface distance of liquids with different densities can be accurately calibrated. The real-time measurement function is provided. The real-time measurement only needs to add three intermediate steps of retracting the ruler slightly again, releasing the ruler and reading again. It is simple and fast. When the ballast water is used to adjust the tilt angle of the ship in the ship tilt test, the adjustment can be successful at one time, avoiding multiple opening and closing operations of the water pump, saving labor and time costs.

[0036] The rolling element 7 is a roller rotatably arranged on the floating block 2, and the tape measure goes around the roller, and the friction between the roller and the tape measure is used to drive the roller to rotate. When the tape measure ring contracts, the tape measure ring drives the roller to move upward. In other embodiments of the present application, the rolling element 7 can also be a rotating shaft or other structures.

[0037] In order to make the depth dimension measurement more accurate, a density calibration piece 8 is fixed on the inner wall of the shell 1, and the tape ring passes through the density calibration piece 8. When the float 2 is suspended in different liquids, the density calibration piece 8 is used to calibrate the depth error caused by different liquid densities.

[0038] Furthermore, the density calibration part 8 in the present application specifically includes a bracket 81 fixed on the inner wall of the shell 1 and a density calibration scale 82 arranged on the bracket 81. A vertical through-gap is reserved between the bracket 81 and the density calibration scale 82. The tape measure ring passes through the gap up and down. There are scales on the tape measure. The density calibration scale can be used to calibrate a specific depth dimension to further improve the measurement accuracy.

[0039] Wherein, a 1.0 standard scale line is provided on the float block 2 for liquid density calculation.

[0040] The housing 1 in the present application includes an upper housing 11 and a lower housing 12, and a through hole is provided between the upper housing 11 and the lower housing 12; the left tape measure 31 and the right tape measure 41 both extend through the through hole into the lower housing 12, and the size of the lower housing 12 is smaller than that of the upper housing 11, and can be used for hand gripping. The size of the lower housing 12 can specifically match the size of the floating block, and is used as a channel for the floating block to move up and down.

[0041] In the embodiment of the present application, the left handle 5 and the right handle 6 each include a grip section, a connecting section and a mating section which are connected in sequence. The grip section and the mating section are parallel and extend in opposite directions, and the connecting section is perpendicular to the grip section and the mating section. The mating section of the left handle 5 is matched and installed at the center of the left tape measure structure 3, and the mating section of the right handle 6 is matched and installed at the center of the right tape measure structure 4. Rotating the grip section can drive the mating section to rotate, so as to rotate the left tape measure structure 3 and the right tape measure structure 4.

[0042] Furthermore, the matching section of the left handle 5 has an avoidance hole, and the end of the matching section of the right handle 6 is inserted into the avoidance hole to avoid interference between the left handle 5 and the right handle 6.

[0043] Among them, a tape measure tightening structure is provided on the left handle 5 or the right handle 6, which is used to position the left handle 5 and the right handle 6 after the left tape measure structure 3 or the right tape measure structure 4 is rotated to the target position to prevent the left tape measure structure 3 and the right tape measure structure 4 from rotating.

[0044] Further, such as Figure 5 As shown, the tape measure tightening structure is arranged on the left handle 5, the left tape measure 31 is installed on the left handle 2, the left handle 2 has a left handle fitting section 52, the tape measure tightening structure includes a left handle tightening bolt 53 arranged at the end of the left handle fitting section 52 and extending in the left and right directions, the side of the left handle fitting section 52 is provided with a left handle tightening column 54 arranged in a vertical direction, and the end of the left handle tightening bolt 53 is a cone shape with a gradually increasing diameter from right to left. Tightening the left handle tightening bolt 53 will push the left handle tightening column 54 outwards and clamp the upper shell 11 to achieve a tightening effect. If the tape measure tightening structure is arranged on the right handle 6, the right handle 6 has a right handle connecting section 62, and the tape measure tightening structure is arranged in the opposite direction to achieve tightening the handle.

[0045] In the present application, the scale of the tape measure ring is 0.5 times the actual spacing, for example, the actual length is 2m, but the scale mark is only 1m.

[0046] When measuring specifically, the vertex base height value of the sounding tube 9 is set as follows: the 1.0 standard density line of the floating block 2 is aligned with the base surface of the shell 1, and the left handle 5 is turned. When the reading of the tape measure at the density calibration scale is the vertex base height value of the sounding tube 9, the tape measure tightening structure is used to tighten the left handle 5. Then, measure, place the base surface of the sounding scale flat on the vertex base surface of the sounding tube 9, turn the right handle 6, and when the floating block 2 falls to the liquid level height of the liquid tank and suspends, the reading is calibrated according to the density of the liquid tank, which is the liquid level height value of the liquid tank.

[0047] 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 substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
