Technical Field
[0001] This utility model relates to the field of snowmaking machine technology, and in particular to a snowmaking machine with pipeline anti-icing function. Background Technology
[0002] A snowmaking machine is a device that uses artificial technology to convert water into simulated natural snowflakes under specific temperature and humidity conditions. It is widely used in ski resorts, snow parks, film and television set construction, and agricultural low-temperature preservation. Its core function is to break the time and space limitations of natural snowfall and provide stable artificial snow on demand.
[0003] Existing patents offer solutions to the above problems, but existing snowmaking machine water inlet pipes lack anti-icing structures, causing the water in the pipes to easily freeze in low-temperature environments, resulting in pipe blockage or localized frost heave.
[0004] Therefore, a snowmaking machine with anti-icing function for pipelines is proposed. Utility Model Content
[0005] The purpose of this invention is to provide a snowmaking machine with anti-icing function for pipes, which can solve the problem that the water inlet pipe of existing snowmaking machines lacks an anti-icing structure, causing the water in the pipe to easily freeze into ice in low-temperature environments, resulting in pipe blockage or local frost heave.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a snowmaking machine with anti-icing function for pipes, comprising a rotating snowmaking machine body, a water inlet pipe movably connected to the rear side of the rotating snowmaking machine body, a heating mechanism welded to the surface of the water inlet pipe, a heat insulation mechanism welded to the surface of the heating mechanism, the heating mechanism comprising a heating pipe, a heat-conducting pipe, a heating screw, a temperature sensor and a PLC controller, the heating pipe being welded to the surface of the water inlet pipe, the inner wall of the heating pipe being filled with heat-conducting oil, the heat-conducting pipe being welded to the surface of the heating pipe, the heating screw being installed inside the heat-conducting pipe, the temperature sensor being installed at the top of the heat-conducting pipe, the detection end at the bottom of the temperature sensor penetrating and extending to the inside of the heating pipe, and the PLC controller being installed on the left side of the rotating snowmaking machine body.
[0007] Preferably, the heat preservation mechanism includes two heat preservation shells, an electric heat tracing cable, several metal plates, and a protective shell, wherein the heat preservation shells are welded to both sides of the surface of the heat-conducting pipe.
[0008] Preferably, the electric heating cable is installed on the surface of the insulation pipe shell, and the metal plate is welded to the surface of the insulation pipe shell.
[0009] Preferably, the protective casing is welded to the surface of a metal plate, and the protective casing is made of polyurethane foam material.
[0010] Preferably, a mounting shell is welded to the left side of the rotating snowmaking machine body, and the PLC controller is installed inside the mounting shell.
[0011] Preferably, the surface of the heating screw is covered with an insulating protective sleeve, and the surface of the insulating protective sleeve is coated with an anti-corrosion coating.
[0012] Preferably, the bottom surface of the metal plate has several grooves, which are engaged with the surface of the electric heating tape.
[0013] Preferably, the inner wall of the protective tube shell is fitted with a cushioning pad, which is made of rubber and plastic sponge material.
[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. The heating element of this application is directly welded to the surface of the water inlet pipe, and its inner wall is filled with heat-conducting oil. With the heating effect of the heating screw inside the heat-conducting pipe, heat can be quickly transferred to the heat-conducting oil. The heat-conducting oil has good thermal stability and fluidity, and can evenly diffuse heat inside the heating element. This avoids the problems of overheating near the heat source and low temperature far from the heat source caused by traditional heating methods, such as local electric heating. It ensures that the overall temperature of the water inlet pipe is maintained above zero degrees Celsius, completely eliminates dead spots of local icing in the pipe, and ensures that the water supply channel is unobstructed throughout. The detection end of the temperature sensor extends to the inside of the heating element, which can monitor the temperature of the heat-conducting oil in real time and transmit the data to the PLC controller. When the temperature is lower than the set threshold, the PLC controller automatically starts the heating screw. When the temperature is higher than the safety threshold, it automatically stops heating to avoid energy waste caused by continuous heating. This intelligent control mode not only ensures the anti-icing effect of the pipe, but also reduces the energy consumption of the equipment. 2. The insulation mechanism of this application adopts a multi-layer structure of insulation shell, electric heating tape, and protective shell. The inner insulation shell is directly attached to the heat-conducting pipe, which can block the heat generated by the heating mechanism from diffusing to the outside. The middle electric heating tape is installed on the surface of the insulation shell, which can serve as a backup heat source to supplement heat in case of extreme low temperature or temporary failure of the heating mechanism, and prevent the pipe temperature from dropping suddenly. The outer protective shell is made of polyurethane foam material. Polyurethane foam has an extremely low thermal conductivity, which can further isolate the intrusion of cold air from the outside. The three-layer structure works together to significantly improve the insulation effect of the pipe, reduce the temperature control pressure of the heating mechanism, and indirectly extend the service life of the heating components.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Please see Figure 1-5 The present invention provides the following technical solution: A snowmaking machine with anti-icing function for pipes includes a rotating snowmaking machine body 1. A water inlet pipe 2 is movably connected to the rear side of the rotating snowmaking machine body 1. A heating mechanism 3 is welded to the surface of the water inlet pipe 2. A heat preservation mechanism 4 is welded to the surface of the heating mechanism 3. The heating mechanism 3 includes a heating pipe 31, a heat-conducting pipe 32, a heating screw 33, a temperature sensor 34, and a PLC controller 35. The heating pipe 31 is welded to the surface of the water inlet pipe 2. The inner wall of the heating pipe 31 is filled with heat-conducting oil. The heat-conducting pipe 32 is welded to the surface of the heating pipe 31. The heating screw 33 is installed inside the heat-conducting pipe 32. The temperature sensor 34 is installed at the top of the heat-conducting pipe 32. The detection end at the bottom of the temperature sensor 34 penetrates and extends to the inside of the heating pipe 31. The PLC controller 35 is installed on the left side of the rotating snowmaking machine body 1.
[0019] In this embodiment: the rotating snowmaking machine body 1 supports and limits the water inlet pipe 2, heating mechanism 3, and insulation mechanism 4. Simultaneously, the rotating snowmaking machine body 1 has a rotation function, enabling 360-degree horizontal rotation and elevation adjustment. The water inlet pipe 2 guides water flow to the high-pressure nozzle at the front of the rotating snowmaking machine body 1. The heat-conducting oil filling the inner wall of the heating pipe 31 has strong thermal stability and uniform heat conduction, ensuring even heat transfer to the entire area of the water inlet pipe 2, preventing localized freezing. The heat-conducting pipe 32 provides a stable installation space for the heating screw 33 and can simultaneously heat... The heat generated by the screw 33 is concentrated and conducted to the heating tube 31, reducing heat loss to the outside and improving heating efficiency. The heating screw 33 can continuously output heat, and its power can be adjusted by the PLC controller 35 to meet the heating needs under different low-temperature environments. The temperature sensor 34 is inserted into the inner side of the heating tube 31, which can monitor the temperature of the heat transfer oil in real time, providing data support for the PLC controller 35 and avoiding blind heating. The PLC controller 35 receives the signal from the temperature sensor 34 and automatically controls the start and stop of the heating screw 33 to achieve intelligent temperature control for low-temperature start and standard stop.
[0020] Specifically, such as Figure 4 As shown, the heat preservation mechanism 4 includes two heat preservation shells 41, an electric heat tracing cable 42, several metal plates 43 and a protective shell 44. The heat preservation shells 41 are welded to both sides of the surface of the heat-conducting pipe 32.
[0021] Specifically, such as Figure 4 As shown, the electric heating tape 42 is installed on the surface of the insulation pipe shell 41, and the metal plate 43 is welded to the surface of the insulation pipe shell 41.
[0022] Specifically, such as Figure 4 As shown, the protective shell 44 is welded to the surface of the metal plate 43, and the protective shell 44 is made of polyurethane foam material.
[0023] In this embodiment: by setting the insulation shell 41 to be directly attached to the heat conduction pipe 32, the heat of the heating mechanism 3 can be blocked from spreading outward, reducing heat loss and lowering the temperature control load of the heating mechanism 3. The electric heating tape 42 is installed on the surface of the insulation shell 41 and can serve as a backup heat source to supplement heat in case of extreme low temperature or temporary failure of the heating mechanism 3, thus preventing a sudden drop in pipe temperature and forming a double anti-icing guarantee. The metal plate 43 can press the insulation shell 41 tightly to ensure that it is tightly attached to the heat conduction pipe 32, reducing the heat insulation gap. The protective shell 44 can further isolate the intrusion of external cold air, while protecting the internal components from rain, snow and dust corrosion, and extending the service life of the insulation mechanism 4.
[0024] Specifically, such as Figure 3 As shown, a mounting shell 5 is welded to the left side of the rotating snowmaking machine body 1, and the PLC controller 35 is installed inside the mounting shell 5.
[0025] Specifically, such as Figure 2 As shown, an insulating protective sleeve 6 is fitted on the surface of the heating screw 33, and the surface of the insulating protective sleeve 6 is coated with an anti-corrosion coating.
[0026] In this embodiment: by setting the mounting shell 5, a closed protective space can be provided for the PLC controller 35, avoiding direct contact between the controller and outdoor low temperature, rain, snow, and dust, preventing the controller from being damaged or short-circuited due to moisture or low temperature. By setting the insulating protective sleeve 6, direct metal contact between the heating screw 33 and the heat conduction pipe 32 can be isolated, avoiding the risk of leakage caused by the contact between the two, ensuring the electrical safety of the equipment, and preventing the heating screw 33 from being damaged due to short circuit. By setting the anti-corrosion coating, it can resist the possible minor leakage of heat conduction oil in the heating pipe 31 and the corrosion of outdoor humid environment, preventing the heating screw 33 from rusting or being corroded, and extending the service life of the heating screw 33.
[0027] Specifically, such as Figure 4 As shown, the bottom surface of the metal plate 43 has several grooves 7, which are engaged with the surface of the electric heating tape 42.
[0028] Specifically, such as Figure 5 As shown, the inner wall of the protective tube shell 44 is fitted with a cushioning pad 8, which is made of rubber and plastic sponge material.
[0029] In this embodiment: by setting the groove 7, the snap-fit structure with the electric heating cable 42 can restrict the position of the electric heating cable 42, preventing the electric heating cable 42 from shifting or falling off due to equipment movement or vibration, and ensuring that the electric heating cable 42 always fits the heat insulation shell 41. By setting the buffer pad 8, the rubber and plastic sponge itself has a certain heat insulation performance, which can form an additional heat insulation layer between the protective shell 44 and the metal plate 43, further reducing heat loss to the outside and enhancing the overall heat insulation effect. By setting the buffer pad 8 to be made of rubber and plastic sponge material, the rubber and plastic sponge has good elasticity and can absorb the impact force when the protective shell 44 is subjected to external impact, such as wind and snow impact and equipment movement collision, to prevent the internal metal plate 43, electric heating cable 42 and heat insulation shell 41 from being deformed or damaged by impact.
[0030] Working principle: First, the operator guides external water to the high-pressure nozzle at the front of the rotating snowmaking machine body 1 through the water inlet pipe 2, providing a basic water flow for snowmaking. Simultaneously, the heating mechanism 3 is activated, and the heating screw 33 is energized inside the heat-conducting pipe 32, generating heat. The heat-conducting pipe 32 concentrates the heat generated by the heating screw 33 to the heating pipe 31 welded to the surface of the water inlet pipe 2. The heat-conducting oil filling the inner wall of the heating pipe 31 heats up rapidly and, due to its good fluidity and thermal stability, evenly diffuses heat within the heating pipe 31, efficiently transferring heat to the entire area of the water inlet pipe 2, preventing localized freezing due to low temperatures. Then, the electric heating tape 42 installed on the surface of the insulation shell 41 is activated simultaneously as a backup heat source to supplement the heat. If the ambient temperature is extremely low or the heating mechanism... 3. In the event of a brief power fluctuation, the electric heating tape 42 can promptly replenish heat to prevent a sudden drop in the temperature of the water inlet pipe 2. Subsequently, the temperature sensor 34 monitors the temperature of the heat transfer oil in the heating pipe 31 in real time and continuously transmits the temperature data to the PLC controller 35. The PLC controller 35 analyzes the data according to the preset temperature threshold. When the temperature is below two degrees, it automatically controls the heating screw 33 to increase the power and improve the heating efficiency. When the temperature is above eight degrees, it automatically controls the heating screw 33 to stop heating to avoid energy waste caused by continuous heating. Finally, under the dual protection of the heating mechanism 3 and the heat preservation mechanism 4, the water flow in the water inlet pipe 2 remains unobstructed and at a suitable temperature, and is smoothly delivered to the high-pressure nozzle, where it mixes with high-pressure air and atomizes into tiny water droplets. In the low-temperature environment, it solidifies into snow, completing the stable snowmaking operation.
[0031] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
