Description

Technical Field

[0001] The utility model belongs to the technical field of liquid level measurement and relates to a liquid level measuring device for a horizontal storage tank. Background Art

[0002] Most of the existing on-site liquid level gauges for horizontal storage tanks are magnetic flap level gauges, which are generally composed of a float, a guide rod, an external sleeve and a magnetic flap panel. The measurement of the liquid level of this magnetic flap level gauge is through the float driving the guide rod to move, and the guide rod driving the magnetic sheet to flip. When the liquid in the horizontal storage tank rises, the float rises, and the liquid level count value rises. When the liquid in the horizontal storage tank drops, the float drops, and the liquid level count value drops. However, this magnetic flap level gauge has a disadvantage, that is, when the liquid in the tank is transported by a pump, the float will drive the guide rod to move in the direction of the pump. During this process, the guide rod may bend. After the guide rod is bent, the upper limit movement is blocked, resulting in inaccurate subsequent on-site liquid level gauge measurements. The existing patent number is CN218724504U, which is a horizontal tank liquid level measuring device. The device consists of a liquid level gauge and an oil dipstick; the liquid level gauge includes a guide rod, a fastener, a liquid level transmitter and a sheath; the upper end of the guide rod is connected to a handle, and the lower end is connected to the top of the liquid level gauge through a limiter and a temperature transmitter; the fastener is used to adjust the liquid level gauge to a vertical state and fasten the guide rod to the tank mouth of the horizontal tank; the liquid level transmitter is connected to a display controller; the sheath is arranged on the periphery of the guide rod, and small holes with uniform intervals are opened on the wall of the bottom section of the sheath to introduce the liquid in the tank into the sheath.

[0003] The prior art has the following technical defects:

[0004] In the above technical solution, the problem that the float guide rod may bend is solved by using a sheath. However, when the float moves in the sheath, the liquid in the sheath only enters through the small circular hole at the bottom and the gas in the sheath is discharged through the air pressure balance hole at the top. When the liquid in the tank body decreases or increases sharply, the liquid in the sheath cannot be synchronized with the liquid level in the tank body in real time, which can easily cause the information transmitted by the float to lag, resulting in too much or too little liquid in the tank. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a horizontal storage tank liquid level measuring device.

[0006] The utility model discloses a horizontal tank liquid level measuring device, comprising a tank, a guide rod slidably connected in the tank, a float fixedly connected at the bottom of the guide rod, and a fence corresponding to the float arranged in the tank; the fence comprises a plurality of guide posts fixed on the upper and lower inner walls of the tank, and each guide post is evenly arranged circumferentially with the float as the center; the float is in a flower-shaped shape with multiple protruding blocks; and the gaps between the guide posts are matched with the protruding blocks of the float.

[0007] Working process or working principle:

[0008] During operation, when liquid flows in or out through the liquid inlet or outlet pipe, the float can move up and down with the liquid level, and the liquid reserve in the tank can be judged by the external guide rod. The enclosure can prevent the float and the guide rod from swinging when the liquid flows, thereby causing the guide rod to bend. The float is arranged in a flower shape, and multiple guide columns are used to guide and protect the float. There are large gaps between the guide columns. When the liquid surges or decreases suddenly, the liquid between the guide columns can also change in time, which is more sensitive than the existing sheath and hole coordination.

[0009] The upper and lower ends of the enclosure are respectively provided with an upper end cover and a lower end cover, a rotating lock plate is provided on the bottom surface of the lower end cover, a lock groove corresponding to the rotating lock plate is provided on the lower inner wall of the storage tank, and the upper end cover is provided with a seal adapted to the storage tank. The integrity of the guide column can be maintained through the upper end cover and the lower end cover, and loading, unloading and maintenance are convenient.

[0010] The upper end cover is provided with a locking block, and the top of the storage tank is provided with a groove corresponding to the locking block and a fixing assembly. During installation, the locking block on the upper end cover is dropped into the groove, and then the rotating lock plate on the lower end cover is rotated to lock the locking groove at the bottom of the storage tank to complete the installation, and finally the locking block is restricted to the groove by the fixing assembly to achieve fixation.

[0011] The fixing assembly includes a rotating column fixed on the top of the storage tank, a baffle is rotatably connected to the rotating column, an elastic pin is provided on the baffle, and a pin hole corresponding to the elastic pin is provided on the storage tank. The baffle is fixed by rotating the baffle so that the elastic pin on the baffle is automatically inserted into the pin hole, so that the baffle is covered just above the groove, thereby blocking the locking block and preventing it from falling out during work.

[0012] A handle is provided on the top of the upper end cover, which can be convenient for workers to load and unload it, can be easily rotated, and can also be hoisted using tools such as a crane.

[0013] The guide rod is provided with a scale, and the height of the liquid in the storage tank can be accurately judged by the scale on the guide rod.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] Compared with the traditional liquid level meter, the utility model has a fluctuation protection effect on the guide rod, and through multiple guide pillars, the liquid level between the guide pillars can be synchronized with the liquid level in the storage tank at all times, so that the data is more accurate and sensitive.
