Description

Technical Field

[0001] The invention relates to the technical field of measuring the liquid level in a tank, and is a sampling liquid level ruler. Background Art

[0002] Crude oil storage tanks need to be manually checked from time to time to measure the liquid level in the tank. At the end of the month and annual inventory, manual oil dipstick checks are also required for re-measurement. The oil tank is checked at the inspection port on the top of the tank. The inspection port is a guide column with a diameter of 150mm, and the lower part is connected to the liquid surface. When checking the oil tank, the employee puts the oil dipstick into the special inspection slot along the inspection port and reads the size of the tape to calculate the oil height in the tank. At present, automatic liquid level gauges are installed on oil tanks, but in order to prevent problems with the automatic liquid level gauge, manual re-measurement is still necessary. At present, manual inspection uses iron wire to pull and measure oil, which not only poses a safety hazard, but also has insufficient measurement accuracy and is inconvenient to use.

DETAILED DESCRIPTION

[0015] The present invention is not limited by the following embodiments, and specific implementation methods can be determined based on the technical solution of the present invention and actual conditions.

[0016] In the present invention, for the convenience of description, the relative position relationship of each component is described according to the attached Figure 1 The positional relationships such as front, back, top, bottom, left, and right are described according to the layout directions of the drawings in the specification.

[0017] The present invention will be further described below in conjunction with embodiments and drawings: Embodiment 1: As attached Figure 1 , 2 As shown in Figures 3 and 4, the sampling level gauge comprises a scale 1, a sampling tube 2, a reset spring 5, a connecting rod 6, an upper protective cap 3, a lower sealing plug 7 and a handle 11. The left side of the scale 1 is evenly distributed with scale marks that increase from bottom to top in the vertical direction. The sampling tube 2 is detachably installed on the right side of the scale 1, and the lower end of the sampling tube 2 is located above the lower end of the scale 1; an upper protective cap 3 is fixedly installed on the outer side of the upper end of the sampling tube 2, a connecting rod 6 is arranged in the sampling tube 2, a reset spring 5 installed in the protective cap is fixedly installed on the upper end of the connecting rod 6, a lower sealing plug 7 capable of blocking the lower end of the sampling tube 2 is fixedly installed on the lower end of the connecting rod 6, a guide vertical groove 12 that is connected inside and outside and can be connected to the guide vertical groove 12 is provided on the outer side of the sampling tube 2 corresponding to the upper position of the connecting rod 6, and a limiting transverse groove 13 that is connected inside and outside and can be connected to the guide vertical groove 12 is provided on the outer side of the sampling tube 2 corresponding to the lower end position of the guide vertical groove 12, and a handle 11 is fixedly installed at the inner end of the guide vertical groove 12 at the corresponding position of the outer side of the connecting rod 6. During use, the handle 11 is pulled down to move to the limiting horizontal groove 13 to release the blockage of the lower end of the sampling tube 2 by the lower sealing plug 7, so that the liquid in the liquid tank can enter the sampling tube 2 from the lower end of the sampling tube 2 to complete the sampling of the liquid; the handle 11 is moved to the guide vertical groove 12, so that the lower sealing plug 7 moves up under the action of the reset spring 5 to achieve the blockage of the lower end of the sampling tube 2 to prevent the liquid in the sampling tube 2 from leaking after the sampling is completed; the liquid level height of the oil, water and emulsion in the sampling tube 2 after sampling is read by the ruler 1, and the type of the sampled liquid can be clearly identified; the present invention is made entirely of materials that do not generate static electricity, sparks and explosion-proof, and is more convenient, safer and more accurate than the existing oil dipstick. It can not only accurately measure the liquid level height of each liquid in the liquid tank, but also clearly distinguish the type of liquid in the liquid tank, realizing the two-in-one function of sampling and measurement.

[0018] The specific use steps of the present invention are: (1) Pull down the handle 11 and move it from the guide vertical groove 12 to the limit horizontal groove 13. At this time, the downward movement of the handle 11 drives the connecting rod 6 and the lower sealing plug 7 to move downward relative to the sampling tube 2, thereby releasing the blockage of the lower end of the sampling tube 2 by the lower sealing plug 7; (2) Slowly place it into the liquid tank and wait for 5 to 20 seconds after the lower end of ruler 1 reaches the bottom of the liquid tank; (3) Move the handle 11 from the limit horizontal groove 13 to the guide vertical groove 12. At this time, the connecting rod 6 and the lower sealing plug 7 move upward relative to the sampling tube 2 under the action of the restoring force of the return spring 5, so that the lower sealing plug 7 blocks the lower end of the sampling tube 2, and the liquid in the liquid tank is sealed in the sampling tube 2; (4) Slowly lift it out of the liquid tank; (5) By reading the liquid level values ​​of oil, water and emulsion in the sampling tube 2 on the scale 1, the type of liquid in the sampling tube 2 can be clearly observed and identified from the sampling tube 2.

[0020] Embodiment 3: As attached Figure 1 , 2 , 3, and 4, it also includes a C-shaped buckle 10. A plurality of C-shaped buckles 10 are evenly spaced from top to bottom on the right side of the ruler 1. The sampling tube 2 is detachably mounted on the right side of the ruler 1 through the C-shaped buckle 10. In use, such an arrangement facilitates the detachable mounting of the ruler 1 and the sampling tube 2 together.
