AI Technical Summary
The prior art has inaccurate problems when measuring the thickness of sludge in horizontal oil tanks, especially when there is less sludge. The positioning plate is blocked due to the arc shape of the tank body, and it takes a lot of time to perform each measurement. Clean up.
A multi-functional measuring tool for easy use is designed, including components such as fixtures, sliders, sleeves, measuring rods and sponges. By moving the sleeve down to its bottom to contact the lower wall of the oil tank, the measuring rod gradually slides down by gravity when measuring the thickness of the sludge. The first sponge absorbs oil to ensure accurate measurement. After the measurement is completed, the sludge is pushed out by pushing the measuring rod and cleaned with a second sponge and oil scraping ring.
Accurate measurement of the sludge thickness in the horizontal oil tank is achieved, avoiding the inaccurate measurement problems caused by arc-shaped tank bodies, and greatly reducing the preparation time before subsequent measurements through the cleaning mechanism.

Abstract
Description
Technical Field
[0001] The invention relates to the technical field of measuring tools, and in particular to a multifunctional measuring tool that is easy to use. Background Art
[0002] Storage tanks for various types of waste oil in oil fields will deposit a thick layer of semi-solid sludge at the bottom of the tanks after long-term use. The thickness of the deposited sludge needs to be measured regularly so that emptying and desilting measures can be taken in time.
[0003] According to the Chinese patent with patent publication number CN105423858A: A sludge thickness measuring device at the bottom of a waste oil tank, this patent uses the sludge resistance when the unfolded long rod component is inserted into the tank bottom to push the positioning plate of the measuring device to slide on the insertion rod and self-lock, so as to accurately measure the sludge thickness at the bottom of the tank. However, when measuring the sludge in a horizontal oil tank, since the tank body of the horizontal oil tank is in an arc shape, when the sludge in the horizontal oil tank is less, the positioning plate will be blocked by the arc shape of the tank body of the horizontal oil tank and move down, resulting in inaccurate measurement results.
[0004] Furthermore, when multiple oil tanks need to be measured continuously, a large amount of oil sludge will adhere to the positioning plate after each measurement. In order to ensure the accuracy of the next measurement result, a lot of time is needed to clean it. Summary of the invention
[0005] In order to overcome the shortcomings that the existing device cannot measure the horizontal oil tank and a large amount of sludge will adhere to the detection component after each measurement, which requires a lot of time to clean, the present invention provides a multifunctional measuring tool that is easy to use.
[0006] The technical solution is: a multifunctional measuring tool that is easy to use, including a fixed frame and a slider; the fixed frame is connected to the slider in a damping sliding manner; it also includes a sleeve, a measuring rod and a first sponge; the slider is connected to the sleeve in a sliding manner; a strip-shaped through groove is provided on the upper side of the sleeve, and a notch is provided at the upper end of the strip-shaped through groove; a scale line is provided on the upper side of the sleeve; a measuring rod for measuring the thickness of sludge in the oil tank is provided in the sleeve, and the measuring rod can slide and rotate freely in the sleeve; an indicating rod is provided at the upper end of the measuring rod; a strip-shaped accommodating groove is provided on the lower side of the measuring rod, and a first sponge for absorbing oil is provided in the strip-shaped accommodating groove, and the lower end of the first sponge is fixedly connected to the lower wall of the strip-shaped accommodating groove; a first strip-shaped groove is provided on the lower side of the measuring rod; a second strip-shaped groove matching the shape of the first strip-shaped groove is provided on the first sponge, and the first strip-shaped groove is connected to the second strip-shaped groove.
[0007] Furthermore, it also includes an extrusion block and an extrusion rod; the extrusion block is fixedly connected to the upper end of the first sponge; the extrusion block is located in the strip-shaped receiving groove; the extrusion rod is detachably plugged into the measuring rod, and the extrusion rod passes through the sleeve.
[0008] Furthermore, a filter screen is arranged in the first strip groove.
[0009] Furthermore, the opening edge of the bottom of the sleeve is configured to be sharp.
[0010] Furthermore, it also includes a second sponge and an oil scraper ring; the second sponge is fixedly connected to the lower side of the slider; the oil scraper ring is fixedly connected to the lower side of the slider through a connecting rod, and the oil scraper ring is located at the lower side of the second sponge; the second sponge and the oil scraper ring are both in a fit state with the sleeve.
[0011] Furthermore, a plurality of rubber convex strips are arranged on the contact surface between the fixing frame and the oil tank opening.
[0012] Furthermore, a collection groove is provided at the bottom of the measuring rod.
[0013] Furthermore, the bottom of the strip-shaped through groove is five to ten centimeters below the zero mark of the scale line.
[0014] Furthermore, the collecting groove is hemispherical.
[0015] Furthermore, the sleeve is configured as a multi-section assembly structure.
[0016] The present invention has the following advantages: First, the sleeve is moved downward until its bottom contacts the lower wall of the oil tank. During this process, the oil first enters the sleeve from the bottom opening of the sleeve. Then, when the bottom of the sleeve contacts the upper surface of the sludge, the sludge begins to enter the sleeve from the bottom opening of the sleeve. When the bottom of the sleeve fits the lower wall of the oil tank, the thickness of the sludge at that location in the oil tank can be known by measuring the distance between the upper surface of the sludge inside the sleeve and the bottom of the sleeve. Then, due to the action of gravity, the measuring rod and the parts connected thereto gradually slide downward. During this process, the oil entering the strip-shaped receiving groove is quickly absorbed by the first sponge, so that the oil in the sleeve is quickly reduced, so that the measuring rod can move downward smoothly. When the measuring rod moves downward to its bottom and contacts the upper surface of the sludge in the sleeve, the measuring rod is blocked by the sludge in the sleeve, so that it cannot move downward further. At this time, by checking which scale of the scale line the indicating rod is aligned with, the thickness of the sludge at that location in the oil tank can be known.
[0017] 2. After the measurement is completed, the sludge in the sleeve is pushed downward out of the sleeve by pushing the measuring rod, and the sleeve is driven to move upward. The oil scraper ring on the lower side of the second sponge is used to scrape the oil and sludge on the outside of the sleeve, and most of the oil and sludge on the outside of the sleeve are scraped off. The second sponge is then used to further clean the outside of the sleeve, thereby effectively ensuring the cleaning effect of the outside of the sleeve for the next measurement operation;
[0018] 3. After each measurement is completed, the slider is pushed to slide a specified distance in the fixed frame, and then the above operation is repeated to achieve multiple measurements of the sludge thickness at different positions to ensure the accuracy of the measurement. Since the diameter of the sleeve and the pipe wall are small, the sludge will not be squeezed in a large range during each measurement, thereby avoiding pushing the sludge to cause changes in the sludge thickness, effectively ensuring the accuracy of the measurement;
[0019] The present invention also has the following beneficial effects:
[0020] The measuring rod is moved until the collection groove is outside the sleeve, and then the sludge at the bottom of the oil tank enters the collection groove. The indicating rod is then pushed upward to drive the sludge in the collection groove into the sleeve, thereby sampling the sludge in the oil tank, making the present invention rich in functions and convenient to operate.

[0037] It also includes an extrusion block 101 and an extrusion rod 102; the extrusion block 101 is fixedly connected to the upper end of the first sponge 5; the extrusion block 101 is located in the strip-shaped receiving groove 4003; the extrusion rod 102 is detachably plugged into the measuring rod 4, and the extrusion rod 102 passes through the sleeve 3.
[0038] A filter is disposed in the first strip groove 4002 .
[0039] The bottom opening edge of the sleeve 3 is sharp.
[0040] It also includes a second sponge 201 and an oil scraper ring 202; the second sponge 201 is fixedly connected to the lower side of the slider 2; the oil scraper ring 202 is fixedly connected to the lower side of the slider 2 through a connecting rod, and the oil scraper ring 202 is located at the lower side of the second sponge 201; the second sponge 201 and the oil scraper ring 202 are both in a fit state with the sleeve 3.
[0041] A plurality of rubber convex strips are arranged on the contact surface between the fixing frame 1 and the oil tank opening to enhance the stability of the fixing frame 1 fixed on the oil tank opening.
[0042] The working principle of the above embodiment is as follows:
[0043] When working, if the thickness of sludge in the oil tank needs to be measured, Figure 2 As shown, the device is placed vertically at the opening of the oil tank, and the fixing frame 1 is clamped and fixed at the opening of the oil tank. In the initial state, the indicator rod 4001 is located in the gap of the strip-shaped through groove 3001, as shown in FIG. Figure 3 As shown, the measuring rod 4 is limited so that it cannot move downward. Figure 5 As shown, the lower inner side of the sleeve 3 now contains a cavity.
[0044] Then, by manually holding the handle, the sleeve 3 and the parts connected to it are driven to move downward on the slider 2 until the bottom of the sleeve 3 contacts the lower wall of the oil tank. In this process, since the oil tank contains a small amount of oil and sludge, and due to the effect of gravity, the oil is located above the sludge, so that when the sleeve 3 gradually moves downward, the oil in the upper layer first enters the interior of the sleeve 3 from the bottom opening of the sleeve 3, and then when the bottom of the sleeve 3 contacts the upper surface of the sludge, the sludge begins to enter the interior of the sleeve 3 from the bottom opening of the sleeve 3. When the bottom of the sleeve 3 fits the lower wall of the oil tank, at this time, it is only necessary to measure the distance between the upper surface of the sludge inside the sleeve 3 and the bottom of the sleeve 3 to know the sludge thickness at that location in the oil tank. It should be noted that when the oil and sludge enter the cavity on the lower side of the sleeve 3, because the measuring rod 4 can slide and rotate freely in the sleeve 3, the air can move through the gap between the two, and then the air in the sleeve 3 is discharged from the through hole above the sleeve 3 for inserting the extrusion rod 102.
[0045] Then the indicating rod 4001 is separated from the notch of the strip through groove 3001, so that the indicating rod 4001 can slide freely downward in the strip through groove 3001. Due to the effect of gravity, the measuring rod 4 and the parts connected thereto gradually slide downward. During this process, the bottom of the measuring rod 4 first contacts the oil located in the upper layer, and then the oil enters the strip receiving groove 4003 from the first strip groove 4002. Then, the oil entering the strip receiving groove 4003 is quickly absorbed by the first sponge 5, so that the oil in the sleeve 3 is quickly reduced, so that the measuring rod 4 can continue to move downward smoothly. When the oil content of the lower part of the first sponge 5 is high, When the oil absorption capacity decreases, the oil that is not absorbed by the lower part of the first sponge 5 can flow upward along the second strip groove 5001, thereby absorbing this part of the oil through the upper part of the first sponge 5, effectively ensuring the oil absorption speed of the first sponge 5, and then ensuring the downward movement speed of the measuring rod 4. When the measuring rod 4 moves down to its bottom and contacts the upper surface of the sludge in the sleeve 3, the measuring rod 4 contacts the sludge over a large area and is blocked by the sludge in the sleeve 3, making it unable to move further downward. At this time, by checking which scale of the indicator rod 4001 is aligned with the scale line 3002, the sludge thickness at that location in the oil tank can be known.
[0046] Then, after measuring the sludge thickness at the location, the sleeve 3 is manually driven to move upward, and the indicating rod 4001 is pushed downward, thereby pushing the measuring rod 4 to push the sludge adhered to the inner wall of the sleeve 3 downward out of the sleeve 3, and in the process of the sleeve 3 moving upward, the second sponge 201 slides relatively with the sleeve 3, so that the oil adhered to the outer side of the sleeve 3 is wiped and absorbed by the second sponge 201, so as to clean the outer side of the sleeve 3 for the next use. Furthermore, since there is still sludge adhered to the outer side of the sleeve 3, Moreover, the oil absorption capacity of the second sponge 201 is limited, so if the outer side of the sleeve 3 is directly wiped by the second sponge 201, the second sponge 201 will soon lose its cleaning effect due to a large amount of oil and sludge adhering to it, so the oil scraper ring 202 on the lower side of the second sponge 201 is used to scrape the oil and sludge on the outer side of the sleeve 3, and most of the oil and sludge on the outer side of the sleeve 3 are scraped off, and then the outer side of the sleeve 3 is further cleaned by the second sponge 201, thereby effectively ensuring the cleaning effect of the outer side of the sleeve 3.
[0047] After the outer side of the sleeve 3 is cleaned, the indicator rod 4001 is driven to reset upward, and the measuring rod 4 is moved upward. When the indicator rod 4001 moves upward to be flush with the notch of the bar groove 3001, the indicator rod 4001 is driven to rotate counterclockwise from top to bottom, so that the indicator rod 4001 is stuck in the notch of the bar groove 3001, and then the measuring rod 4 is fixed. Fig. 9As shown, the squeezing rod 102 is inserted downward into the measuring rod 4, and the squeezing rod 102 is pushed downward by the squeezing rod 102, and then the first sponge 5 is squeezed downward by the squeezing block 101, and the first sponge 5 is compressed, so that the oil in the first sponge 5 is squeezed out, and after flowing through the first strip groove 4002, it flows downward out of the sleeve 3 from the lower side opening of the sleeve 3, thereby removing the oil in the first sponge 5 for the next measurement.
[0048] It should be noted that in order to ensure the accuracy of the measurement, after completing a measurement, the slider 2 can be pushed to slide a specified distance in a fixed direction in the fixed frame 1, and then the above operation can be repeated to measure the sludge thickness below the location. The above operation can be repeated to measure the sludge thickness at different locations to ensure the accuracy of the measurement. In addition, since the diameter and pipe wall of the sleeve 3 are small, the sludge will not be squeezed on a large scale during each measurement, thereby avoiding pushing the sludge when inserted into the sludge for measurement, causing the sludge thickness to change, and effectively ensuring the accuracy of the measurement.
[0049] According to the above working principle, we know that the present invention has the following effects:
[0050] The sleeve 3 is moved downward until its bottom contacts the lower wall of the oil tank. During this process, the oil first enters the sleeve 3 from the bottom opening. Then, when the bottom of the sleeve 3 contacts the upper surface of the sludge, the sludge begins to enter the sleeve 3 from the bottom opening. When the bottom of the sleeve 3 fits the lower wall of the oil tank, the distance between the upper surface of the sludge inside the sleeve 3 and the bottom of the sleeve 3 is only needed to measure the distance, so as to know the sludge thickness at that place in the oil tank. Then, due to the effect of gravity, the measuring rod 4 and its connected The connected parts gradually slide downward, and in this process, the oil entering the strip receiving groove 4003 is quickly absorbed by the first sponge 5, so that the oil in the sleeve 3 is quickly reduced, so that the measuring rod 4 can move downward smoothly. When the measuring rod 4 moves down to its bottom and contacts the upper surface of the sludge in the sleeve 3, the measuring rod 4 is blocked by the sludge in the sleeve 3 and cannot move further downward. At this time, by checking which scale of the indicator rod 4001 fits with the scale line 3002, the sludge thickness at that location in the oil tank can be known.
[0051] After the measurement is completed, the sludge in the sleeve 3 is pushed downward out of the sleeve 3 by pushing the measuring rod 4, and the sleeve 3 is driven to move upward, and the oil scraper ring 202 on the lower side of the second sponge 201 is used to scrape the oil and sludge on the outside of the sleeve 3, so that most of the oil and sludge on the outside of the sleeve 3 are scraped off, and then the outside of the sleeve 3 is further cleaned by the second sponge 201, thereby effectively ensuring the cleaning effect of the outside of the sleeve 3.
[0052] After each measurement is completed, the slider 2 is pushed to slide a specified distance in the fixed frame 1, and then the above operation is repeated to achieve multiple measurements of the sludge thickness at different positions to ensure the accuracy of the measurement. Since the diameter of the sleeve 3 and the pipe wall are small, the sludge will not be squeezed on a large scale during each measurement, thereby avoiding pushing the sludge to cause changes in the sludge thickness, effectively ensuring the accuracy of the measurement.
[0053] On the basis of the above technical effects, the present invention also has the following advantages:
[0054] A filter screen is disposed in the first strip groove 4002 , thereby effectively preventing suspended particles in the oil from entering the first strip groove 4002 and causing the first strip groove 4002 to be blocked.
[0055] The bottom opening of the sleeve 3 is provided with a sharp edge, thereby effectively reducing the difficulty of inserting the sleeve 3 into the mud.
[0056] The rubber convex strips provided on the contact surface between the fixing frame 1 and the oil tank opening effectively increase the friction between the fixing frame 1 and the oil tank opening, thereby enhancing the stability of the fixing frame 1 fixed on the oil tank opening.
[0057] Example 2
[0058] On the basis of Example 1, Figure 6 , Fig.10 and Fig.11 As shown, a collection groove 4004 is provided at the bottom of the measuring rod 4.
[0059] The bottom of the strip-shaped through groove 3001 is five to ten centimeters below the zero mark of the scale line 3002 .
[0060] The collecting groove 4004 is hemispherical and easy to clean.
[0061] The sleeve 3 is configured as a multi-section assembly structure, and internal components are easy to disassemble.
[0062] The working principle of the above embodiment is as follows:
[0063] After the measurement of the sludge thickness in the oil tank described in Example 1 is completed:
[0064] The existing method also samples and analyzes the sludge in the oil tank to evaluate the quality of the stored oil. If the sludge in the oil tank needs to be sampled, the indicator rod 4001 is pushed downward to the bottom of the L-shaped vertical side. Fig.11 As shown, the measuring rod 4 moves to the collecting groove 4004 outside the sleeve 3, so that the sludge at the bottom of the oil tank enters the collecting groove 4004, and then pushes the indicating rod 4001 upward, thereby driving the sludge in the collecting groove 4004 to enter the sleeve 3, and then the device is removed from the oil tank, thereby realizing sampling of the sludge in the oil tank.
[0065] According to the above working principle, we know that the present invention has the following effects:
[0066] The measuring rod 4 is moved to the collecting groove 4004 outside the sleeve 3, and then the sludge at the bottom of the oil tank enters the collecting groove 4004, and then the indicating rod 4001 is pushed upward to drive the sludge in the collecting groove 4004 to enter the sleeve 3, thereby sampling the sludge in the oil tank, making the present invention rich in functions and convenient to operate.
