The top end of the measuring rod is welded and fixed with a liquid level meter top flange. The bottom end of the measuring rod is elastically connected with an oil tank bottom mounting member. When the ship is repaired, the following problems are faced when reloading or replacing the soft cable type measuring rod and the float: most of the existing installation methods are installed and fixed by multiple bolts. It is not convenient to quickly disassemble during maintenance, thereby affecting work efficiency. CONTENT OF THE UTILITY MODEL

[0003] To achieve the above purpose, the following technical solutions are used.

[0004] A liquid level measuring device for ship oil tank includes a base and a soft cable type measuring rod. The soft cable type measuring rod is sleeved with a float. The bottom of the soft cable type measuring rod is fixedly provided with a fixed seat. The fixed seat is located inside the base. The base is symmetrically provided with cavities inside. Each cavity is slidably provided with a stop block. The stop block is fixedly connected with the inner wall of the cavity through a spring. The top of the base is symmetrically connected with a screw rod through threads. The bottom of the screw rod is in abutment with the top of the stop block.

[0005] The bottom of the stop block is in abutment with the fixed seat. The top of the stop block is obliquely arranged. The stop block is symmetrically provided with a sliding block on both sides. The inner wall of the cavity is symmetrically provided with a sliding groove. The sliding block moves along the sliding groove.

[0006] The bottom of the screw rod is fixedly provided with a protrusion. The bottom of the protrusion is obliquely arranged. The inclined surface of the bottom of the protrusion is in abutment with the top of the stop block. The top of the screw rod is provided with a hexagonal recess.

[0007] Compared with the prior art, the utility model has the following beneficial effects:

[0008] The utility model has the advantages of simple structure, convenient installation and use, convenient assembly and disassembly, convenient quick disassembly during maintenance, improved work efficiency, limiting the fixed seat through the stop block, moving the stop block outward by rotating the screw rod during disassembly, and disassembling the fixed seat. The overall device has simple structure, convenient operation and higher practicality. BRIEF DESCRIPTION OF DRAWINGS

[0013] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0014] Referring to the accompanying drawings, a liquid level measuring device for a ship's oil tank includes a base 1 and a flexible cable measuring rod 2. A float 3 is fitted around the outer ring of the flexible cable measuring rod 2, and a fixing seat 4 is fixedly installed at the bottom of the flexible cable measuring rod 2. The fixing seat 4 is located inside the base 1. The base 1 has symmetrically opened cavities, and a stop 5 is slidably installed inside each cavity. The stop 5 is fixedly connected to the inner wall of the cavity by a spring 6. The top of the base 1 is symmetrically threaded with screws 7, and the bottom of the screws 7 abuts against the top of the stop 5.

[0015] The bottom of the stop block 5 abuts against the fixed base 4, and the top of the stop block 5 is inclined. This structural design facilitates the installation of the fixed base 4. Slider blocks 8 are symmetrically fixed on both sides of the stop block 5, and sliding grooves are symmetrically opened on the inner wall of the cavity. The sliders 8 move along the sliding grooves.

[0016] A protrusion is fixedly provided at the bottom of the screw 7. The bottom of the protrusion is inclined and the inclined surface of the bottom of the protrusion abuts against the top of the stop block 5. A hexagonal groove is provided at the top of the screw 7.

[0017] When using this device, the base 1 is fixed to the bottom of the oil tank. The flexible cable measuring rod 2 is fixed to the fixed seat 4. The fixed seat 4 is placed into the base 1 and abuts against the stop block 5. Then the fixed seat 4 is locked in place. When disassembling the fixed seat 4, the screw 7 is rotated to drive the protrusion to move downward and squeeze the top of the stop block 5, so that the stop block 5 moves outward and releases the restriction on the fixed seat 4, thereby allowing the fixed seat 4 to be removed and replaced.

[0018] It should be pointed out finally that the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit the same; and although the present application has been described in detail with reference to the foregoing embodiments, it should be appreciated by those skilled in the art that the technical solutions recorded in the foregoing embodiments can be modified, or some technical features thereof can be replaced equivalently; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
