DETAILED DESCRIPTION
[0029] In order to make the technical scheme of the utility model or the prior art clearer, the following will briefly introduce the drawings needed to be used in the embodiment or the prior art description. Obviously, the drawings described in the following description are some embodiments of the utility model, and other drawings can be obtained by those skilled in the art without creative labor on the premise that they do not pay creative labor.
[0030] In winter, when the metal roof of each factory is troubled by accumulated snow, the traditional manual snow removal method is often difficult to effectively implement. Since the roof position is high, manual snow removal not only has great operation difficulty, but also has significant safety risks. In addition, relying on natural sunlight to melt the accumulated snow is extremely low in efficiency, especially under the condition of continuous snowfall or low temperature, the accumulated snow will continue to accumulate. This accumulated snow will cause continuous pressure on the roof structure, which may further cause serious accidents such as roof collapse, not only affecting the normal use of the building, but also posing a serious threat to personnel safety.
[0031] For example, Figure 1As shown, the metal roof snow melting system of the embodiment of the utility model, including: gas cylinder 1, storage tank 2 and snow melting assembly 3. Among them, gas cylinder 1 is suitable for being installed on roof through support, for storing gas;Storage tank 2 is used to store snow melting agent;Snow melting assembly 3 includes oscillator 31, snow melting agent delivery pipe 32, first gas delivery pipe 33 and second gas delivery pipe 34, oscillator 31 is communicated with gas cylinder 1 through first gas delivery pipe 33, pulse valve 35 is arranged on first gas delivery pipe 33, storage tank 2 is communicated with first gas delivery pipe 33 through snow melting agent delivery pipe 32, pneumatic check valve 36 is arranged on snow melting agent delivery pipe 32, one end of second gas delivery pipe 34 is connected to gas cylinder 1, the other end of second gas delivery pipe 34 is connected to snow melting agent delivery pipe 32, electromagnetic valve 37 is arranged on second gas delivery pipe 34;Among them, the connecting point of second gas delivery pipe 34 on snow melting agent delivery pipe 32 is located on the inlet side of pneumatic check valve 36. In addition, the connecting point of snow melting agent delivery pipe 32 on first gas delivery pipe 33 is located on the outlet side of pulse valve 35.
[0032] Specifically, oscillator 31 generates sweeping type oscillation jet flow by means of Coanda effect principle, and strengthens the cleaning efficiency of roof snow. Specifically, the oscillation airflow released by oscillator 31 can penetrate the snow and penetrate into the interior thereof, so that the structure of the snow becomes loose. Among them, oscillator 31 can adopt the oscillator 31 in the prior art, and the structure of the embodiment of the utility model is not further improved. Illustratively, oscillator 31 includes an oscillation cavity, two feedback channels respectively arranged on both sides of the oscillation cavity and communicated with the oscillation cavity, a nozzle and an inlet respectively arranged at both ends of the oscillation cavity, the feedback channel includes a feedback channel inlet close to the nozzle and communicated with the oscillation cavity and a feedback channel outlet close to the inlet and communicated with the oscillation cavity, the inlet and the oscillation cavity are connected to form an inlet throat, and a turbulence fluid for increasing fluid instability and affecting the thickness of the oscillation cavity side wall boundary layer is arranged in the middle of the oscillation cavity. Among them, the inlet throat satisfies: T≤0.7mm and A / T≤1.2, or 0.7mm≤T≤2m and A / T≤0.25;Wherein, T is the width of the inlet throat, and A is the height of the inlet throat.
[0033] It should be particularly pointed out that when the electromagnetic valve 37 is not started, the pneumatic check valve 36 can rely on its unique structural design to build a reliable barrier to effectively prevent the snow melting agent from flowing unexpectedly due to the influence of gravity or residual pressure in the pipeline, thereby ensuring the stability of the system in the static state and significantly reducing the potential risk. When the electromagnetic valve 37 is activated, the high-pressure gas in the gas cylinder 1 will quickly inject into the snow melting agent conveying pipe 32 through the second gas conveying pipe 34, forming a strong driving force. At this time, the pneumatic check valve 36 will quickly and accurately react, remove the previous blocking state, and guide the snow melting agent to pass through the pneumatic check valve 36 at a high speed and stable state driven by the high-pressure gas, and then enter the first gas conveying pipe 33. Subsequently, the snow melting agent will be conveyed to the oscillator 31 together with the high-pressure gas in the first gas conveying pipe 33.
[0034] In actual application scenarios, the metal roof snow melting system has two working modes. The first mode is to start the pulse valve 35 alone, at which time the high-pressure gas in the gas cylinder 1 will first be pressurized through the pulse valve 35, and then use the sweeping action generated by the oscillator 31 based on the Coanda effect to remove the snow on the roof. If the snowfall is large or the snow duration is long, the second mode can be switched to, that is, the electromagnetic valve 37 is opened at the same time. In this mode, the snow melting agent will pass through the pneumatic check valve 36 and be conveyed to the oscillator 31 together with the high-pressure gas in the first gas conveying pipe 33, so as to realize the synergistic effect of high-pressure gas and snow melting agent, and promote the melting of snow together.
[0035] The metal roof snow melting system of the embodiment of the utility model utilizes the Coanda effect principle to generate a sweeping oscillating jet, strengthens the cleaning efficiency of the snow on the roof, supports the synchronous conveying of high-pressure gas and snow melting agent, significantly improves the snow melting efficiency, ensures that the snow on the roof can be quickly and completely removed, and thereby reduces the pressure and damage risk of the snow on the building.
[0036] In optional embodiments, as shown in Figure 1 and Figure 2 , the metal roof snow melting system further comprises a gas storage tank 4 and an air compressor 5, and the air compressor 5 communicates with the gas cylinder 1 through the gas storage tank 4.
[0037] It should be noted that the air compressor 5 communicates with the gas cylinder 1 through the gas storage tank 4 to provide high-pressure gas for the gas cylinder 1. The gas storage tank 4 is used to buffer the output of the air compressor 5, ensure the stable supply of gas in the gas cylinder 1, and reduce the frequent start of the air compressor 5, thereby prolonging the service life of the equipment.
[0038] In optional embodiments, as shown in Figure 1 and Figure 2 , the metal roof snow melting system further comprises a pneumatic ball valve 6, and the gas storage tank 4 communicates with the gas cylinder 1 through the pneumatic ball valve 6.
[0039] It should be noted that the pneumatic ball valve 6 is installed on the connecting pipeline between the gas storage tank 4 and the gas cylinder 1, for controlling the gas flow between the gas storage tank 4 and the gas cylinder 1.
[0040] In addition, the metal roof snow melting system is additionally provided with a loose joint 10, and the pneumatic ball valve 6 is installed on the gas cylinder 1 by means of the loose joint 10. In this way, not only the installation and disassembly of the pneumatic ball valve 6 are facilitated, thereby facilitating the subsequent maintenance and replacement work, but also the loose joint 10 can effectively compensate for the displacement and deformation of the pipeline that may occur during operation. This greatly improves the flexibility and stability of the pipeline connection, while ensuring the sealing of the connection, which helps to prolong the service life of the entire system.
[0041] In optional embodiments, as shown in Figure 1 and Figure 2 , the metal roof snow melting system further comprises a control mainboard 7, and the pulse valve 35 and the electromagnetic valve 37 are electrically connected with the control mainboard 7.
[0042] It should be noted that the control mainboard 7 can issue control instructions according to the weather information sent by the server. The pulse valve 35 and the electromagnetic valve 37 are opened according to the instructions, and the high-pressure gas and the snow melting agent are delivered to the oscillator 31 according to the predetermined program. The oscillator 31 generates a sweeping air flow by using the Coanda effect to remove the snow on the roof. In addition, according to the snowfall situation, the control mainboard 7 can adjust the working frequency and time length of the pulse valve 35 and the electromagnetic valve 37 to achieve efficient snow melting.
[0043] It can be understood that the air compressor 5 and the pneumatic ball valve 6 can be electrically connected with the control mainboard 7, and the control mainboard 7 controls the opening and closing of the air compressor 5 and the pneumatic ball valve 6 according to the instructions.
[0044] In optional embodiments, as shown in Figure 1 and Figure 2 , the metal roof snow melting system further comprises an environmental information collector 8, the environmental information collector 8 is adapted to be installed on the roof, and the environmental information collector 8 is electrically connected with the control mainboard 7. The control mainboard 7 is configured to control the actions of the pulse valve 35 and the electromagnetic valve 37 according to the environmental information data sent by the environmental information collector 8. The environmental information collector 8 comprises at least one of a color recognition sensor, a temperature sensor, a humidity sensor, and a thickness sensor.
[0045] It should be noted that the control mainboard 7 receives the data sent by the environment information collector 8, and processes and analyzes it. According to the preset snow melting strategy, the control mainboard 7 judges whether the snow melting system needs to be started and the operating parameters of the snow melting system. When the control mainboard 7 judges that the snow melting system needs to be started, it sends a control instruction to the pulse valve 35 and the electromagnetic valve 37. The pulse valve 35 and the electromagnetic valve 37 are opened according to the instruction, and the high-pressure gas and the snow melting agent are transported to the oscillator 31 according to the predetermined program. The oscillator 31 generates a sweeping gas flow by using the Coanda effect to remove the snow on the roof. The control mainboard 7 dynamically adjusts the working frequency and duration of the pulse valve 35 and the electromagnetic valve 37 according to the real-time changes of the environmental information, so as to realize efficient and accurate snow melting.
[0046] For example, when the color recognition sensor detects that the roof area presents white, it will quickly transmit this signal to the control mainboard 7. After receiving the signal, the control mainboard 7 immediately starts the air compressor 5, the pneumatic ball valve 6 and the pulse valve 35, thereby starting the delivery process of high-pressure gas. The high-pressure gas first flows through the pulse valve 35, and under the pressure of the pulse valve 35, it is transported to the oscillator 31 and removed from the snow on the roof by the sweeping action generated by the oscillator 31 based on the Coanda effect. If the snowfall is large, the snow duration is long, or the snow depth is deep, the control mainboard 7 will send an instruction to start the electromagnetic valve 37 according to the preset logic judgment. After receiving the instruction, the electromagnetic valve 37 is quickly opened, and the snow melting agent will pass through the pneumatic check valve 36 and be transported to the oscillator 31 together with the high-pressure gas in the first gas delivery pipe 33, thereby realizing the synergistic effect of high-pressure gas and snow melting agent to promote the melting of snow and effectively improve the snow melting efficiency and effect.
[0047] In an optional embodiment, the metal roof snow melting system further comprises a heater installed on the gas cylinder 1. It should be noted that the heater is installed on the outside or inside of the gas cylinder 1, and the temperature of the gas in the gas cylinder 1 is increased by electric heating or gas heating, so as to further improve the snow melting efficiency.
[0048] In an optional embodiment, as shown in Figure 1 In an optional embodiment, as shown in
[0049] In an optional embodiment, as shown inFigure 1 As shown, the storage tank 2 is installed on the gas cylinder 1. Exemplarily, the storage tank 2 is fixedly installed on the top of the gas cylinder 1 by a support. In addition, the number of the snow melting assemblies 3 is multiple, and the multiple snow melting assemblies 3 are symmetrically arranged relative to the storage tank 2. That is, the multiple snow melting assemblies 3 are symmetrically arranged relative to the storage tank 2, which ensures uniform snow melting effect and improves snow melting efficiency.
