Description

Technical Field

[0001] The utility model belongs to the technical field of water level monitoring equipment, and in particular relates to an antifreeze electronic water gauge. Background Art

[0002] Electronic water gauge is an instrument used to monitor water level. It obtains data by measuring the water level of the electrode. It is used to monitor water level in water conservancy projects such as rivers, lakes, reservoirs, hydropower stations, irrigation areas and water transfer. It is also suitable for monitoring water level in municipal projects such as tap water, urban sewage treatment, and urban road waterlogging.

[0003] At present, most of the water level monitoring adopts upright water gauge, whose structure is to fix the water gauge plate on the water gauge pile. In winter, due to the lack of good preventive measures, the water level cannot be manually observed due to ice around the water gauge. In this case, the observers usually use ice hammers, ice shovels, ice spoons and other tools to manually break and remove ice around the water gauge before observing the water level.

[0004] Some hydrological stations use radar water level meters or electronic water gauges to observe water levels. However, electronic water gauges are prone to electronic components freezing and malfunctioning. Testers still need to break the ice before they can conduct manual observations.

[0005] Breaking the ice can easily damage the water gauge, is time-consuming, affects the real-time acquisition of water level information, is labor-intensive, and causes great inconvenience to water level testing work.

[0006] Therefore, an antifreeze electronic water gauge is provided, which is suitable for rivers and lakes with frozen water surfaces. Utility Model Content

[0007] The technical problem to be solved by the utility model is to provide an antifreeze electronic water gauge in view of the deficiencies of the above-mentioned prior art. The antifreeze electronic water gauge has a simple structure, is easy to use, can work normally during the winter freezing period, and is suitable for rivers and lakes where the temperature drops and the water surface freezes.

[0008] In order to solve the above technical problems, the technical solution adopted by the utility model is: an antifreeze electronic water gauge, characterized in that it includes an outer cylinder, a lower end cover is fixedly connected to the bottom end of the outer cylinder, and water inlets are arranged on both sides of the lower end cover. The water inlets are not drawn in the accompanying drawings, and the water inlets are used to connect to an external water source.

[0009] An upper end cover is fixedly connected to the top of the outer cylinder, and an electronic water gauge is arranged inside the outer cylinder. The electronic water gauge can be equipped by different manufacturers. To ensure the safety of personnel, a 36-volt low-voltage power supply is adopted, which is converted from a 220-volt power supply into a 36-volt DC power supply via a high-power switching power supply 2000W.

[0010] The electronic water gauge is fixedly connected to the lower end cover and the upper end cover, an electric heating rod is fixedly installed on the lower end cover, an anti-dry burning temperature controller is fixedly installed on the inner wall of the outer tube, and the anti-dry burning temperature controller is electrically connected to the electric heating rod.

[0011] After the stable freezing period, the anti-dry-burn temperature controller determines whether the electric heating rod needs to work based on the water temperature in the outer cylinder.

[0012] When the water temperature is less than or equal to degrees Celsius, the anti-dry-burning temperature controller controls the electric heating rod to start working.

[0013] When the water temperature is greater than or equal to degrees Celsius, the anti-dry-burning temperature controller controls the electric heating rod to stop working.

[0014] When the water level is lower than the electric heating rod and dry-burning occurs, the anti-dry-burning temperature controller controls the electric heating rod to not perform heating work.

[0015] In this embodiment, the bottom end of the lower end cover is sleeved in the base, and the outer cylinder is installed through the base.

[0016] Preferably, a column is vertically fixedly installed on the side end of the base, and a clamp is fixedly installed on the column. The clamp is used to fix the outer cylinder. The outer cylinder is fixed to the column by using the clamp, so as to stabilize the outer cylinder.

[0017] Preferably, the column is made of No. 1 channel steel, and a guide groove is provided on the column to facilitate disassembly and assembly.

[0018] Preferably, a connecting groove is provided at the bottom end of the lower end cover, and a connecting block is fixedly installed in the base, and the connecting block cooperates with the connecting groove, so that the connection is more stable.

[0019] Preferably, the outer cylinder and the upper end cover are made of PE material, which has low thermal conductivity and can achieve a certain thermal insulation effect.

[0020] Compared with the prior art, the utility model has the following advantages:

[0021] The utility model installs the electronic water gauge in the outer cylinder through the upper end cover and the lower end cover, and an electric heating rod is arranged on the lower end cover. When the outside temperature is too low, the electric heating rod heats the water in the outer cylinder to prevent the water inside and outside the outer cylinder from cooling down and freezing, which would cause the electronic water gauge to be damaged and malfunction. The utility model ensures that the electronic water gauge can be used normally, and the water level information can be obtained in real time during the freezing period in winter, which reduces the labor intensity of the staff and improves the work efficiency.
