Description

Technical Field

[0001] The utility model relates to the technical field of heating equipment, in particular to a gate anti-freezing device. Background Art

[0002] In cold regions, rivers tend to freeze in winter, posing a serious threat to the normal operation of hydraulic structures, especially gates. Once gates are stuck or frozen by ice, water level regulation may fail, affecting functions such as flood control and drainage, navigation, and water resource management, and even causing structural damage. To meet this challenge, existing anti-icing measures for gates mainly include physical deicing, chemical ice melting, and local heating.

[0003] The local heating method uses electric heating wires to heat the key areas in a targeted manner. However, in actual applications, the heating wires are directly immersed in water and are prone to moisture and short circuits. In addition, most heating wires are fixed at a certain height. As the water level changes, the heating wires cannot accurately heat the surface water that is most prone to freezing, resulting in energy waste. In addition, the installation and fixing method is single and difficult to adapt to gates of different sizes and types. Therefore, a gate anti-freezing device is used to solve the above problems. Utility Model Content

[0009] As a preferred gate anti-freezing device of the utility model, a heat conducting plate is provided at the bottom of the buoy.

[0010] As a preferred gate anti-freezing device of the utility model, the suspension mechanism includes a mounting plate, a suspension arm and a fastening bolt, the suspension arm is fixedly mounted on the upper end of the mounting plate, the suspension arm is an "n"-shaped rod structure, and the fastening bolt is mounted on the suspension arm and threadedly connected thereto.

DETAILED DESCRIPTION

[0023] See also Figure 1-Figure 5 , a gate anti-freezing device, comprising a heating wire 1, the outer end of which is provided with a floating mechanism 2 and a suspension mechanism 3;

[0024] The heating wire 1 is installed in the floating mechanism 2, and the floating mechanism 2 is slidably installed at the front end of the suspension mechanism 3. The floating mechanism 2 includes a buoy 201, a sealing cover 202, a fixed pressure strip 203 and a fixed screw rod 204. An inspection port 2015 is provided on the top of the buoy 201. The sealing cover 202 is detachably installed in the inspection port 2015. The fixed pressure strip 203 is installed at the upper end of the sealing port and is rotatably connected to the buoy 201. A first ear plate 2013 is provided on the buoy 201, a second ear plate 2032 is provided on the pressure strip, a slide groove 2033 is provided on the second ear plate 2032, a screw hole 2014 is provided on the first ear plate 2013, and the fixed screw rod 204 passes through the slide groove 2033 and the screw hole 2014 in sequence and is threadedly connected to the buoy 201.

[0025] Furthermore, a sealing ring 2021 is provided on the lower end surface of the sealing cover 202 , and a fixing protrusion 2031 is provided on the top lower end surface of the fixing pressure strip 203 .

[0026] The squeezing effect of the fixed pressure strip 203 on the fixed protrusion 2031 is improved by the fixed protrusion 2031, thereby increasing the pressure of the sealing cover 202 on the float 201. In combination with the sealing ring 2021 structure, the sealing performance of the inspection port 2015 is improved to prevent water from entering the inspection port 2015 and causing damage to internal circuit equipment.

[0027] Furthermore, a heat-conducting interlayer 2016 is provided in the float 201, heat-conducting oil is provided in the heat-conducting interlayer 2016, the heating wire 1 is immersed in the heat-conducting oil, an oil temperature sensor 2017 is provided in the heat-conducting interlayer 2016, a water temperature sensor 2018 is provided on the heat-conducting plate 205, and a controller 2019 electrically connected to the heating wire 1, the oil temperature sensor 2017 and the water temperature sensor 2018 is provided in the float 201.

[0028] When the water temperature sensor 2018 detects that the water temperature is too low and close to zero degrees, it is transmitted to the controller 2019. The controller 2019 starts the heating wire 1 for heating. The heating wire 1 is heat-conducted by the heat-conducting oil, so that the heating wire 1 evenly heats the buoy 201 and heats the upper river water near the gate to prevent the water from freezing. When the oil temperature sensor 2017 transmits the heat-conducting oil temperature to the controller 2019 and the temperature reaches the preset temperature, the heating wire 1 is turned off to avoid energy waste.

[0029] Furthermore, a heat conducting plate 205 is provided at the bottom of the buoy 201 .

[0030] The contact area and depth between the buoy 201 and the water flow are increased by the heat conducting plate 205, thereby increasing the heating area of ​​the river water, thereby increasing the antifreeze area and improving the antifreeze effect.

[0031] Furthermore, the suspension mechanism 3 includes a mounting plate 301, a suspension arm 302 and a fastening bolt 303. The suspension arm 302 is fixedly mounted on the upper end of the mounting plate 301. The suspension arm 302 is an "n"-shaped rod-like structure. The fastening bolt 303 is mounted on the suspension arm 302 and is threadedly connected thereto.

[0032] The mounting plate 301 is suspended above the gate plate of the gate through the suspension arm 302, so that the suspension arm 302 is clamped on the front and rear end surfaces of the gate plate, and then the fastening bolts 303 are tightened to squeeze the gate plate, thereby fixing the suspension mechanism 3 to the gate plate, facilitating rapid installation between equipment, and the structure of the fastening bolts 303 enables the equipment to adapt to gate plates of different thicknesses, thereby improving the scope of application of the equipment.

[0033] Furthermore, a slide rail 3011 is disposed on the front end surface of the mounting plate 301 , a slider 2011 is disposed on the back side of the buoy 201 , and the buoy 201 and the mounting plate 301 are slidably connected through the slider 2011 and the slide rail 3011 .

[0034] The buoy 201 can slide up and down along the slide rail 3011, so that the buoy 201 always floats on the surface of the water area, thereby continuously heating the surface of the river, preventing the river from freezing near the gate, and maximizing the utilization rate of thermal energy.

[0035] Furthermore, a ceramic roller 2012 is provided on the inner end surface of the slider 2011 .

[0036] The friction between the slider 2011 and the slide rail 3011 is reduced by the ceramic roller 2012, thereby improving the smoothness of the sliding of the float 201. The ceramic roller prevents the ceramic from rusting and corroding due to long-term immersion in water, thereby improving the service life of the equipment.

[0037] When the device is in use, first, hang the mounting plate 301 above the gate of the gate, ensure that the two ends of the suspension arm 302 can be firmly stuck in the front and rear ends of the gate, then, tighten all the fastening bolts 303 evenly until the suspension arm 302 is firmly fixed on the gate, align the slide rail 3011 at the front end of the mounting plate 301 with the slide groove 2033 on the back of the buoy 201, slowly slide the buoy 201 onto the slide rail 3011, ensure smooth sliding, then turn on the power, observe whether the heating wire 1 is working normally, whether the buoy 201 can maintain the expected floating state, and whether the heating effect reaches the expected, especially the heating condition and antifreeze effect of the surface water area, regularly check the fastening condition of the suspension mechanism 3, the sealing property of the sealing ring 2021, the working condition of the heating wire 1 and the floating condition of the buoy 201 to ensure that the device is in good working condition.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
