Description

Technical Field

[0001] This utility model relates to the field of measuring instrument technology, and in particular to a portable measuring tool used in oily wastewater storage facilities. Background Technology

[0002] In the process of oil extraction and chemical processing, a storage facility is dug near the work site to collect and temporarily store materials that may be accidentally leaked during operations, as well as normal operational waste liquids, in order to prevent them from seeping into the soil and groundwater and causing environmental pollution. These storage facilities mainly contain oil-water mixtures. In order to assess the operating status of extraction or production equipment during the extraction or production process, identify the source of problems, and guide adjustments, it is necessary to measure the distribution ratio of oil and water in the storage facility.

[0003] The current method for measuring the oil and water distribution ratio in storage facilities involves applying oil and water testing paste to a dipstick. This requires first inserting the dipstick into the liquid to check the approximate position, then removing it, applying the testing paste, and measuring again. Furthermore, the testing paste must be wiped off after each measurement, which is quite cumbersome. Utility Model Content

[0004] To overcome the cumbersome technical problem of measuring oil-water mixtures using a dipstick, which requires submerging the dipstick in the liquid to determine the approximate position, then removing it, applying testing paste, and measuring again, and then wiping off the testing paste after each measurement, this invention provides a portable measuring tool for use in oily wastewater storage facilities.

[0005] The technical solution of this utility model is: a portable measuring tool for use in oily wastewater storage facilities, including a fixed sleeve, a multi-stage telescopic tube installed inside the fixed sleeve, a connecting plate installed on the lowest tube of the multi-stage telescopic tube, and two fixing grooves opened on the connecting plate, with test paper adhered to both fixing grooves by adhesive strips.

[0006] Furthermore, the two test strips are used to detect oil and water, respectively.

[0007] Furthermore, a rotating shaft is rotatably connected inside the fixed sleeve. The rotating shaft is located inside the multi-stage telescopic tube. A connecting ring is installed at the upper end of each section of the multi-stage telescopic tube. A spline rod is rotatably connected to the connecting ring. The upper and lower adjacent spline rods are splined together. A lead screw is installed at the lower end of the lowest spline rod. The lead screw is threadedly connected to the pipe thread of the connecting plate installed inside the multi-stage telescopic tube.

[0008] Furthermore, a connecting box is installed on the upper part of the fixed sleeve. A rotating rod is rotatably connected inside the connecting box. A worm gear is installed on the rotating rod. A worm that meshes with the worm gear is rotatably connected inside the connecting box. A hand crank that is fixed to the worm is rotatably connected to the connecting box. Both the rotating shaft and the rotating rod are equipped with pulleys. A belt is sleeved between the two pulleys, and this belt passes through the connecting box and the fixed sleeve.

[0009] Furthermore, a foot pedal bracket is rotatably connected to the outer side of the fixed sleeve. The foot pedal bracket is located below the connecting box. A limit block is installed on the outer side of the fixed sleeve. The limit block is located below the rotatable connection between the fixed sleeve and the foot pedal bracket.

[0010] Furthermore, a connecting shell is installed on the side of the foot pedal bracket away from the fixed sleeve. A sliding rod and a limiting rod one are slidably connected inside the connecting shell. The sliding rod is located on the side of the limiting rod one away from the fixed sleeve. The sliding rod and the limiting rod one are rotatably connected. A spring is connected between the limiting rod one and the connecting shell. A connecting block is installed at the upper end of the fixed sleeve. The connecting block is in a limiting fit with the limiting rod one. A limiting rod two is installed on the sliding rod. The connecting shell is provided with a limiting groove. The limiting rod two slides in the limiting groove.

[0011] Compared with the prior art, the present invention has the following advantages: The present invention uses test paper that is adhered by adhesive strips, which can be peeled off directly after use, making it easy to clean and enabling a quick second measurement. At the same time, the foot pedal bracket forms a stable T-shaped structure, allowing the multi-stage telescopic tube to enter the storage facility to be tested vertically, ensuring the accuracy of the test.

Detailed Implementation

[0022] The technical solution will be further described below with reference to specific embodiments. It should be noted that the terms "up," "down," "left," and "right" used in this document refer only to the position of the structure shown in the corresponding drawings. The serial numbers assigned to components in this document, such as "first," "second," etc., are only used to distinguish the described objects and have no sequential or technical meaning. Unless otherwise specified, terms such as "connection" and "linkage" in this application include both direct and indirect connections (linkages).

[0023] A portable measuring tool for use in oily wastewater storage facilities, such as Figures 1-4 As shown, it includes a fixed sleeve 1, inside which a multi-stage telescopic tube 101 is installed. The tube at the bottom of the multi-stage telescopic tube 101 is equipped with an arc-shaped connecting plate 102. Two fixing grooves 103 are opened on the connecting plate 102. Test strips 104 are attached to the two fixing grooves 103 by adhesive strips. The two test strips 104 are used to detect water and oil respectively. Taking the detection of oil as an example, when it comes into contact with oil, it will change color to determine whether there is oil in the storage facility.

[0024] like Figure 5 and Figure 6 As shown, a rotating shaft 2 is rotatably connected inside the fixed sleeve 1. The rotating shaft 2 is located inside the multi-stage telescopic tube 101. A connecting ring 201 is installed at the upper end of each section of the multi-stage telescopic tube 101. A spline rod 202 is rotatably connected to the connecting ring 201. The upper and lower adjacent spline rods 202 are splined together. A lead screw 203 is installed at the lower end of the lowest spline rod 202. The lead screw 203 is threadedly connected to the connecting plate 102 installed inside the multi-stage telescopic tube 101.

[0025] like Figure 2 and Figure 7 As shown, a connecting box 3 is installed on the upper part of the fixed sleeve 1. A rotating rod 301 is rotatably connected inside the connecting box 3. A worm gear 302 is installed on the rotating rod 301. A worm 303 that meshes with the worm gear 302 is rotatably connected inside the connecting box 3. A hand crank 304 that is fixed to the worm 303 is rotatably connected to the connecting box 3. Both the rotating shaft 2 and the rotating rod 301 are equipped with pulleys 305. A belt is sleeved between the two pulleys 305, and this belt passes through the connecting box 3 and the fixed sleeve 1.

[0026] like Figure 8 As shown, a foot support 4 is rotatably connected to the outer side of the fixed sleeve 1. The foot support 4 is located below the connecting box 3. A limit block 401 is installed on the outer side of the fixed sleeve 1. The limit block 401 is located below the rotatable connection between the fixed sleeve 1 and the foot support 4. The foot support 4 is limited by the limit block 401, so that the foot support 4 and the fixed sleeve 1 form a stable T-shaped structure. This allows the multi-stage telescopic tube 101 to enter the storage facility vertically, avoiding tilting or shaking that may occur when lowered by hand, thus ensuring the test results.

[0027] like Figure 2 , Figure 8 and Figure 9 As shown, a connecting shell 5 is installed on the side of the foot pedal bracket 4 away from the fixed sleeve 1. A sliding rod 501 and a limiting rod 502 are slidably connected inside the connecting shell 5. The sliding rod 501 is located on the side of the limiting rod 502 away from the fixed sleeve 1. The sliding rod 501 and the limiting rod 502 are rotatably connected. A spring is connected between the limiting rod 502 and the connecting shell 5. A connecting block 503 is installed at the upper end of the fixed sleeve 1. The connecting block 503 is in a limiting fit with the limiting rod 502. A limiting rod 504 is installed on the sliding rod 501. The connecting shell 5 is provided with a limiting groove 505. The limiting rod 504 slides within the limiting groove 505.

[0028] Specifically, after the measuring personnel arrive at the location to be tested next to the storage facility, they first adjust the number of extended sections according to the approximate measurement depth. During this process, each extended section of pipe moves the adjacent spline rod 202 via the adjacent connecting ring 201. Then, the measuring personnel rotate the slide rod 501, causing the second limiting rod 504 to disengage from the transverse groove of the limiting groove 505. Under the action of the spring between the first limiting rod 502 and the connecting shell 5, the first limiting rod 502 moves towards the slide rod 501 and away from the limiting hole on the connecting block 503. At this time, the measuring personnel rotate the foot pedal bracket 4, so that the side of the foot pedal bracket 4 contacts the upper side of the limiting block 401. Then, the measuring personnel gradually insert the multi-stage telescopic tube 101 into the storage facility to be tested, and make the foot pedal bracket 4 contact the ground. Then, the personnel rotate the hand crank. Crank 304, a hand crank 304, drives shaft 2 to rotate via worm 303, worm wheel 302, rotating rod 301 and two pulleys 305. Shaft 2 drives spline rod 202 to rotate via spline. The lowermost spline rod 202 drives screw 203 to rotate, thereby driving the lowermost section of multi-stage telescopic tube 101 to move downward. This precisely adjusts the position of test paper 104. After measurement, the above steps are repeated in reverse to retract multi-stage telescopic tube 101. Then, observe whether the two test papers 104 change color to determine whether the storage facility contains oil and water. Based on the color change position of the water test paper 104 and the extension length of the lowermost section of multi-stage telescopic tube 101, the color change depth of the test paper 104 is obtained, thus determining the distribution ratio of oil and water in the storage facility.
