As shown in fig. 1, a liquid level detection device for a bio-oil tank comprises a limiting pipe 2, a communicating pipe 3, a marking pipe 4, a floater 5, a counterweight ball 6 and an indicating ball 7, wherein a liquid inlet is formed in the bottom of the limiting pipe 2, a balance hole is formed in the upper part of the limiting pipe 2, one end of the communicating pipe 3 is communicated with the top of the limiting pipe 2, and the other end of the communicating pipe 3 is communicated with the top of the marking pipe 4; a partition plate 13 which divides the identification tube 4 into a left cavity and a right cavity is arranged in the identification tube 4, the floater 5 is movably arranged in the limiting tube 2, the counterweight ball 6 is movably arranged in the left cavity of the identification tube 4, the indicating ball 7 is movably arranged in the right cavity of the identification tube 4, the counterweight ball 6 is connected with the floater 5 through a first silk thread 11, and the counterweight ball 6 is connected with the indicating ball 7 through a second silk thread 12; the lateral wall of the mark tube 4 corresponding to the indication ball 7 is provided with scale marks, and the lateral wall of the mark tube 4 corresponding to the indication ball 7 is a transparent lateral wall.
When in use, the limiting pipe 2 is arranged in the oil tank 1, and the marking pipe 4 is arranged outside the tank. In this embodiment, the weight of the float 5 is greater than the weight of the weight ball 6, and the weight of the weight ball 6 is greater than the weight of the indicating ball 7. A medium enters the limiting pipe 2 from the liquid inlet, when the liquid level rises, the floater 5 rises along with the liquid level, the counterweight ball 6 descends, and the indicator ball 7 rises under the action of the second silk thread 12; when the liquid level drops, the floater 5 drops along with the liquid level because the weight of the floater 5 is larger than that of the counterweight ball 6, and the counterweight ball 6 rises under the action of the first wire 11, so that the indicating ball 7 drops. In practice, the indicating ball 7 is provided with marked lines corresponding to the scale lines, and the liquid level position can be read through the scale lines corresponding to the marked lines on the indicating ball 7. The pipe diameter of the limiting pipe 2 is 1.5-2 times of the diameter of the floater 5, and the influence of media or impurities on the pipe wall on the floater 5 is fully avoided. In this embodiment, limitThe cross section area of the position tube 2 is 10mm2～10000mm2. The balance hole enables the mark pipe 4, the limiting pipe 2 and the oil tank 1 to be communicated with each other, air pressure in the limiting pipe 2 and the mark pipe 4 is balanced, and influence of the air pressure on the floater 5 and the indicating ball 7 is avoided. In this embodiment, the hole area of the balance hole is 2mm2～1000mm2. In practice, taking a horizontal palm oil storage tank as an example, the gauge of the floater 5 is 50 × 50mm, the diameter of the limiting pipe 2 is 80mm, the diameter of the balance hole is 10mm, the weight of the floater 5 is 50g, the weight of the counterweight ball 6 is 30g, and the weight of the indicator ball 7 is 25 g.

The counterweight ball 6 is connected with the floater 5 and the indicating ball 7 through the pulley, so that the friction force between the pipe wall and the silk thread is fully reduced, the influence of the friction force on reading is reduced, and the reading precision is improved.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof.
