AI Technical Summary
In extremely cold winter weather, the water surface in the water level well is prone to freezing, causing the water level gauge to malfunction and making it impossible to monitor the water level.
The system adopts an inner and outer sleeve structure, with foam glue filling the space between the inner and outer sleeves. A heating cable is laid on the inner sleeve wall, and the operation of the heating cable is controlled by a temperature sensor and a control module to keep the water surface temperature in the well above 0℃ and prevent freezing.
It effectively prevents the water surface in the water level well from freezing, ensures the water level gauge works normally around the clock, and realizes all-weather monitoring of the water level.

[0014] The embodiment comprises a water level logging body 1, which is formed by sleeving an inner sleeve 2 and an outer sleeve 3, the inner sleeve 2 and the outer sleeve 3 are filled with foam glue 4, the inner sleeve 2 is provided with a heating cable 5 on the wall, the heating cable 5 is connected with a control module 6, and the control module 6 is connected with a temperature sensor 7. The inner sleeve 2 is provided with a water level gauge supporting plate 8 on the top. A plurality of water inlet holes 9 are formed in the side wall of the inner sleeve 2. The outer sleeve 3 is provided with a logging cover 10 on the top.
[0015] The water level logging heat preservation system of the utility model, the water level logging body 1 utilizes the form of inner and outer sleeves, fills the heat preservation material-foam glue 4 between the inner sleeve 2 and the outer sleeve 3, and prevents water seepage by using sealing glue at both ends. The inner sleeve 2 and the outer sleeve 3 are filled in the form of all filling, so that the water in the water level logging body 1 does not freeze and the water level gauge works normally under the condition of low temperature in winter. The heating cable 5 with a length of 1 meter and a power of 300 W is laid on the wall of the inner sleeve 2 of the water level logging body 1, and the temperature sensor 7 is installed in the inner sleeve 2. The F400-PLC automatic control module 6 is used to detect the logging water surface temperature and control the working of the heating cable 5. When the logging water surface temperature is lower than 2 DEG C, the automatic control module 6 supplies power to the heating cable 5, and the heating cable 5 works. When the logging water surface temperature is higher than 5 DEG C, the automatic control module 6 stops supplying power, and the heating cable 5 stops working. In this way, the logging water surface temperature can be kept above 0 DEG C at all times, and the water surface is prevented from freezing. Even in extremely cold weather, the water surface in the water level logging body will not freeze, and the water level gauge can work normally all day long. If the water level logging body 1 is close to the central control room or workstation, the automatic control cabinet can be connected, and the temperature in the water level logging body 1 and the working condition of the heating cable 5 can be displayed in real time on the computer monitoring platform. The heat preservation system reflects the concept of digital water conservancy and smart water conservancy, has a wide application prospect and high popularization value.
