本发明涉及水位测量仪器技术，属于自动化领域，尤其涉及一种投入式水位计通用防坠器，能够对投入式水位计起到保护作用。The invention relates to water level measuring instrument technology and belongs to the field of automation. In particular, it relates to a universal anti-falling device for a submersible water level gauge, which can protect the submersible water level gauge.
背景技术Background technique
目前，水位测量中所使用的水位计多为投入式水位计、激光式水位计、浮球水位计等。其中投入式水位计由于使用方便，原理简单在模拟量水位测量中使用最多。现有的投入式水位计一般用一个紧固螺母将测量电缆固定在法兰盘上，使用时水位计全部重量集中于固定螺母。平时由于重力作用或者冬季低温电缆冷缩，固定螺母会承受较大的拉力，如果发生脱落，会直接拉扯内部二次接线，甚至整个线缆脱离法兰，掉入水轮机流道等危及其他重要设备的区域。At present, most of the water level gauges used in water level measurement are input water level gauges, laser water level gauges, float water level gauges, etc. Among them, the input water level meter is the most used in analog water level measurement due to its ease of use and simple principle. Existing submersible water level meters generally use a fastening nut to fix the measurement cable on the flange. When in use, the entire weight of the water level meter is concentrated on the fixing nut. Normally due to the effect of gravity or the cold shrinkage of the cable at low temperatures in winter, the fixing nut will bear a large pulling force. If it falls off, it will directly pull the internal secondary wiring, or even the entire cable will detach from the flange and fall into the turbine flow channel, endangering other important equipment. Area.
