Description

Technical Field

[0001] The present invention relates to the technical field of roof gutters, and particularly relates to an ice removal module applicable to a siphon drainage system of a roof gutter. Background Art

[0002] With the development of the economy, more and more steel structure projects are applied to industrial production. In light steel structure industrial factory buildings, with the increase in building area, when the snowfall is large in winter, a large amount of accumulated snow on the steel structure roof greatly increases the load on the steel structure roof, causing problems such as deformation, water seepage, cracks, and even collapse of the steel structure roof. For the problem of ice and snow cleaning on the steel structure roof, the currently common snow melting methods include manual snow removal, mechanical snow removal, installation of air blowers for snow removal, etc., and there are also cases where heating cables or electric tracing tapes are arranged on the outer surface of the steel structure roof for melting ice and snow on the roof. As the building area of the steel structure increases day by day, the size of the gutter on the steel structure roof is also getting larger and larger. For roof snow melting, the snow melting on the surface of the gutter cannot be ignored either. In the severe winter, if the ice and snow on the roof accumulate in the gutter and are not melted and drained in time, it is not only easy to block the gutter outlet, but also easy to generate a large load on the roof, affecting structural safety, and it is also easy to form backflow, which will also cause damage to the internal machinery and equipment, etc. Therefore, the technical requirements for gutter ice and snow melting are becoming more and more strict.

[0003] However, there are still some deficiencies in the current treatment technologies for snow melting and ice thawing in gutters. For example, whether it is a roof snow melting system or a gutter snow melting system, only the snow melting electric tracing system is considered to be arranged on the roof surface and the gutter surface, while the melting ice and snow at the gutter eaves on the roof are ignored. For example, the existing patent technology with the publication number CN107859251A and the patent name of an electric tracing system for gutter snow melting specifically discloses that "it includes a gutter, heating tape A, drain outlet A, drain outlet B, downspout A, downspout B, end junction box, special rain and snow measurement and control device, temperature sensor, humidity sensor, intelligent temperature control distribution box, power connection box, insulation layer, power cable, signal cable, wire mesh, snow melting clip, fixing device, heating tape B and heating tape C. The electric tracing system for gutter snow melting of the present invention sets multiple electric tracings to suit various gutter structures and sets multiple electric heating tape fixing devices to ensure the stability of the heating tape in various usage environments". However, in the above patent, only the heating tape is horizontally laid inside the gutter, and the snow or ice cubes at the gutter eaves on the roof cannot be processed. With the improvement of people's pursuit of building aesthetics and the requirements for building functions, large-span special-shaped steel structure roofs are becoming more and more common. In winter, the upper eaves of the special-shaped roof gutters are prone to icing, forming "ice cones" and other shapes that block the upper eaves of the gutter. Firstly, it makes it difficult for the rainwater on the roof to drain during the ice and rain weather, resulting in water accumulation at the upper eaves of the gutter. Secondly, the "ice cones" and other shapes formed at the eaves will suddenly fall when melting, which may cause a certain degree of damage to structures such as the gutter surface, thus damaging the structure of the gutter and causing the gutter to leak.

[0004] Regarding the problem of snow melting and ice thawing inside the gutter, like the above-mentioned disclosed patent technology, most of the current solutions are to arrange multiple electric heating tapes or heating cables inside the gutter, using the temperature difference to play the role of snow melting and ice thawing. However, precisely because of the temperature difference, it will cause a temperature effect inside the metal gutter. In the long run, the thermal expansion and contraction phenomenon may lead to the relaxation and looseness of some rod connection parts inside the gutter, etc., resulting in rainwater and the like seeping into the internal structure of the roof during rainy or snowy weather. Invention Summary of the Invention

Secondly, it also solves the problems of poor snow melting coverage area, unobvious snow melting effect and energy saving of the gutter; thirdly, it avoids the phenomenon of thermal expansion and contraction of the siphon drainage gutter water inlet due to the temperature effect, and further causes the separation of the siphon rainwater hopper from the bottom of the gutter, resulting in the problem of water leakage.

The top of the inclined spiral part is provided with a conical drainage part. The gasket is located outside the inclined spiral part, and the inclined spiral part is communicated with the water outlet at the bottom.

[0010] As a further solution of the present invention: the water outlet is communicated with a rainwater pipe provided at the bottom of the gutter. An electric heating tape is further provided inside the rainwater pipe. A junction box is provided on the inner wall of the gutter, and the electric heating tape is connected to the junction box.

[0011] As a further solution of the present invention: the inner gutter snow melting and ice melting component includes a gutter heating tape and a groove opened on the heat conducting plate. The heat conducting plate is provided with a groove in a "snake" shape. The gutter heating tape is laid in the groove, and the gutter heating tape is connected to the solar component on the roof.

[0012] As a further solution of the present invention: the gutter snow melting and ice melting component includes an intelligent spraying member, and the intelligent spraying member further includes a pipeline, a high-pressure nozzle, an automatic spraying control module and a snowfall sensor. Among them, a plurality of high-pressure nozzles are provided and evenly laid on the side wall of the gutter.

Among them, the eaves plug is located at the end of the roof, the heat conduction pad and the heat insulation layer are sequentially laid at the end of the roof, the heating cable is located on the heat conduction pad, and the heating cable is connected to the solar component on the roof.

[0015] As a further solution of the present invention: the eaves snow melting and ice melting component further includes a flashing plate, and the flashing plate is arranged below the eaves plug.

[0016] As a further solution of the present invention: the solar component includes a support beam, a roof panel and a solar panel. The top of the roof is connected to the roof panel through the support beam, and a solar panel is detachably installed on the top of the roof panel.

[0017] As a further solution of the present invention: a roof machine box is arranged inside the roof. The interior of the roof machine box includes an inverter, an energy storage module, a load, a water pressure signal transmission module and a heating control module connected in sequence from top to bottom. Among them, the inverter is connected to the solar component, and the water pressure signal transmission module is connected to the water pressure monitor.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. In this application, a coping snow melting and deicing component is provided at the upper coping of the gutter, and a gutter snow melting and deicing component is also provided inside the gutter. At the same time, a solar component is provided on the roof to supply electrical energy to the two snow melting and deicing components, realizing snow melting and deicing for the upper coping and the interior of the gutter. Meanwhile, a siphonic rainwater hopper is provided at the rainwater outlet in the gutter, and an electric heating tape is installed inside the siphonic rainwater hopper, and a gasket is installed on the siphonic rainwater hopper. Firstly, this setting of the application avoids the sudden fall of the "icicle" and other shapes formed by the icing at the upper coping of the gutter in winter during melting, which may cause a certain degree of damage to the gutter structure, resulting in the problem of gutter water seepage, ensuring all-round snow melting and deicing treatment of the gutter. Secondly, it also solves the problems of poor snow melting coverage area, unobvious snow melting effect and energy conservation of the gutter. Thirdly, it avoids the thermal expansion and contraction phenomenon of the siphonic drainage gutter rainwater hopper under the temperature effect, and further avoids the separation of the siphonic rainwater hopper from the bottom of the gutter, resulting in the problem of water leakage.

[0020] 2. By setting a heating cable (i.e., an electric heating tape) at the upper coping of the gutter, the upper coping of the gutter can melt snow and ice in time in snowy and icy weather, making it not easy to form "icicles" and other shapes and block the upper coping of the gutter, so that the roof is not easy to drain water in rainy and snowy weather. It also avoids the sudden fall of the "icicle" and other shapes during melting, which may cause a certain degree of damage to the gutter structure, resulting in gutter water seepage. At the same time, this device connects the heating cable to the solar photovoltaic panel on the roof, sets a heat conduction cushion layer on the heating cable, and also sets a heat conduction cushion layer for the distance from the lower contact part of the heating cable to the coping, strengthening the heat and area generated by the heating cable. An insulating layer is arranged for the distance from the coping plug to the heating cable below the heat conduction cushion layer to avoid the temperature effect caused by the heat transferred by the heat conduction pad from affecting the lower structure. At the same time, a coping plug is set at the upper coping of the gutter, and a flashing is set below the coping plug to prevent water droplets from seeping into the roof.

[0021] 3. A heat conduction plate with a "snake-shaped" groove is set on the surface of the gutter body, and an electric heating tape is laid in the "snake-shaped" groove of the heat conduction plate, increasing the coverage area of the heating tape in the gutter and solving the problems of small heat generation area and energy conservation of the electric heating tape on the surface of the gutter. The material of the heat conduction plate can preferably be materials with good heat conduction performance such as metal and ceramic. Using less electric heating tape can evenly generate a large area of heat to cover the entire gutter, and melt snow and ice in time in snowy and icy weather. If the area of the gutter is small, the area ratio of the "snake-shaped" groove heat conduction plate can be appropriately reduced, and a "snake-shaped" groove is set inside. The purpose of this device is to generate a large area of heat on the surface of the gutter with less electric heating tape, achieving the effect of timely melting of snow and ice on the basis of energy conservation.

[0022] 4. Intelligent spraying parts are installed on the inner wall of the gutter, which can remove snow from the gutter in winter and cool the gutter in summer. The intelligent spraying parts are composed of pipes, high-pressure nozzles, snowfall sensors and automatic spraying control modules. The pipes are installed on the inner walls on both sides 0.1-0.3m away from the bottom of the gutter. Multiple high-pressure nozzles are designed and installed on the pipes. The spacing between the high-pressure nozzles makes them evenly distributed on the inner wall of the gutter. The pipes are also connected to snowfall sensors and automatic spraying systems. The snowfall sensors can sense the amount of snowfall and temperature. When it snows in winter, when the temperature is below 0℃, After receiving the signal, the snowfall sensor controls the automatic spraying control module to spray snow removal materials (the snow removal materials can be salt water or snow melting agents, etc.). The amount of water sprayed can also be controlled according to the amount of snowfall. Especially when it snows suddenly in the middle of the night, the system will work immediately to prevent the snow from freezing in the gutter. In hot summer weather, the automatic spraying system can be set within a certain temperature range to spray water to cool down, protect components, and extend service life. While melting snow and ice in the gutter, this equipment will not cause temperature differences on the metal roof, which can effectively prevent the metal roof from leaking and becoming loose due to temperature effects.

[0023] 5. A siphon rainwater bucket is set at the rainwater outlet of the gutter body. The lower part of the siphon rainwater bucket is an inclined spiral part. The inclined bolt part can reduce the contact area of ​​heat, thereby reducing the thermal expansion and contraction phenomenon of the siphon rainwater bucket under the temperature effect environment. An integrated siphon rainwater bucket gasket is set at the spiral of the inclined spiral siphon rainwater bucket. The outermost layer of the integrated siphon rainwater bucket gasket is an expansion layer. The expansion layer can enhance the heat dissipation effect of the siphon rainwater bucket. At the same time, the test shows that with the increase of the thickness of the expansion layer, its heat dissipation capacity is increasingly improved; a honeycomb layer is set at the connection with the expansion layer. The honeycomb layer can prevent the gasket from being broken and extended when a certain part is damaged. The honeycomb structure can block the extension of the gasket when it is broken, prevent the gasket from being damaged in a large area, and increase its service life. The combination of the gasket and the siphon rainwater bucket can solve the problem that the contact part between the gutter and the siphon rainwater bucket is affected by the thermal expansion and contraction effect, which affects the waterproof effect of the siphon rainwater bucket gasket;

[0024] 6. A roof machine box is set inside the roof. The roof machine box includes an inverter, an energy storage module, a load, a water pressure signal transmission module and a heating control module which are connected in sequence from top to bottom. The inverter is used to convert the direct current generated by the solar panel into alternating current. The energy storage module is used to store the electric energy converted by the inverter and transmit the electric energy to the power load. The heating control module controls the working status, heating time and temperature adjustment of the electric heating belts in various places. The water pressure signal transmission module is connected to the water pressure monitor. The water pressure signal transmission module is used to transmit the water pressure value in the gutter detected by the water pressure detection system. When the gutter water pressure value is detected to be abnormal, timely inspection and maintenance shall be carried out. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0037] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Apparently, the described embodiments are part of the embodiments of the present invention, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the scope of protection of the present invention.

[0038] Refer to Figure 1 and Figure 7 , an ice removal module applicable to a roof gutter siphon drainage system, comprising a gutter 1, a siphon rainwater hopper 2, an eave snow melting and ice melting assembly 3, a water pressure monitor 4, a solar energy assembly 5, a roof 6, a gutter snow melting and ice melting assembly, a junction box 8, a rainwater pipe 9, an electric heating tape 10 and a heat conducting plate 12, wherein the heat conducting plate 12 is laid on the inner bottom wall of the gutter 1.

[0039] Refer to Figure 1 and Figure 7 , the gutter 1 is arranged at the eave part of the roof 6, a rainwater outlet is opened on the inner bottom wall of the gutter 1, and the siphon rainwater hopper 2 is installed at the rainwater outlet. The bottom of the rainwater outlet is communicated with the rainwater pipe 9, the rainwater pipe 9 is installed at the bottom of the gutter 1, the electric heating tape 10 is arranged inside the rainwater pipe 9 and is connected to the junction box 8 arranged on the inner wall of the gutter 1. An eave snow melting and ice melting assembly 3 is arranged at the upper eave of the gutter 1 to perform snow melting and ice melting treatment at the roof eave to prevent ice cones from forming at the eave and falling into the gutter 1, causing damage to the gutter; a water pressure monitor 4 is arranged on the side wall of the gutter 1 to detect the water pressure inside the gutter 1. A solar energy assembly 5 is also arranged on the roof, and a gutter snow melting and ice melting assembly is arranged inside the gutter 1, which can perform snow melting and ice melting treatment on the inside of the gutter.

[0040] Refer to Figure 3 , the siphon rainwater hopper 2 includes a conical drainage part 21, a gasket 22, an inclined spiral part 23 and a water outlet 24. The conical drainage part 21 is arranged at the top of the inclined spiral part 23, the gasket 22 is located outside the inclined spiral part 23, and the inclined spiral part 23 is communicated with the water outlet 24 at the bottom. During installation, the inclined spiral part 23 is connected to the rainwater outlet pipe, and the gasket 22 is closely attached to the rainwater outlet to ensure the seal between the inclined spiral part 23 and the rainwater outlet pipe. The water outlet 24 is connected to the rainwater pipe 9. During use, rainwater flows from the conical drainage part 21 into the inclined spiral part 23 and then is discharged into the rainwater pipe 9 through the water outlet 24. The electric heating tape 10 can be used to heat the inside of the rainwater pipe 9 to prevent the temperature inside the rainwater pipe 9 from being too low and freezing, causing pipe blockage; it should be noted that by arranging threads on the outside of the inclined spiral part 23, not only the stability during installation is ensured, but also the heat generated by the electric heating tape 10 inside the rainwater pipe 9 can be prevented from generating a temperature effect at the water inlet, strengthening the heat dissipation effect of the siphon rainwater hopper 2.

[0041] Furthermore, referring to Figure 4 , Figure 5 and Figure 6 , the gasket 22 further includes an expansion layer 221 and a honeycomb waterproof layer 222. The expansion layer 221 and the honeycomb waterproof layer 222 are integrally formed to form an integrated gasket. The expansion layer 221 is located on the outer ring of the honeycomb waterproof layer 222. The outermost layer of the gasket 22 is the expansion layer 221, which has the function of enhancing heat dissipation, and the heat dissipation effect becomes stronger as the thickness of the expansion layer increases; the inner layer is the honeycomb waterproof layer, and a honeycomb layer is provided at the connection with the expansion layer. The honeycomb layer can prevent the breakage from spreading when a certain part is damaged, and can ensure the service life of the gasket. It should be noted that the material of the expansion layer is preferably a mixture of expanded graphite, polyvinyl chloride plasticizer, polyvinyl chloride heat stabilizer and filler.

[0042] A further description of the integrated siphonic rainwater bucket gasket is as follows:

[0043] Comparative Example 1: The total diameter of the integrated siphonic rainwater bucket gasket is 100 mm, and the diameter of the honeycomb layer is about 30 mm.

[0044] Example 2: The total diameter of the integrated siphonic rainwater bucket gasket is 100 mm, the diameter of the outermost expansion layer is about 10 mm, and the diameter of the honeycomb layer is about 20 mm.

[0045] Example 3: Similarly, the total diameter of the integrated siphonic rainwater bucket gasket is 100 mm, the diameter of the honeycomb layer is 18 mm, and the diameter of the outermost expansion layer is 12 mm.

[0046] Example 4: Similarly, the total diameter of the integrated siphonic rainwater bucket gasket is 100 mm, the diameter of the honeycomb layer is 16 mm, and the diameter of the outermost expansion layer is 14 mm.

[0047] Example 5: Similarly, the total diameter of the integrated siphonic rainwater bucket gasket is 100 mm, the diameter of the honeycomb layer is 14 mm, and the diameter of the outermost expansion layer is 16 mm.

[0048] Example 6: Similarly, the total diameter of the integrated siphonic rainwater bucket gasket is 100 mm, the diameter of the honeycomb layer is 12 mm, and the diameter of the outermost expansion layer is 18 mm.

[0049] Heat dissipation capacity test: Examples 1-5 in Table 1 are the test results of the integrated gasket;

[0050]

[0051] It can be seen from Table 1 that the surface temperature change of the gaskets in Examples 2-5 is less than 5 °C, while the temperature rise of Comparative Example 1 without the expansion layer is higher than 10 °C, indicating that the new gasket has better heat dissipation capacity, and the heat dissipation capacity is better as the area of the expansion layer increases.

[0052] Referring to Figure 1 and Figure 2 ,the eaves snow melting and ice melting assembly 3 is arranged at the top of the roof and at the upper eaves position of the gutter 1. The eaves snow melting and ice melting assembly 3 includes an eaves plug 31, a heat insulation layer 32, a heat conduction pad 33, a heating cable 34 and a flashing 35. Among them, the eaves plug 31 is located at the end of the roof, the heat conduction pad 33 and the heat insulation layer 32 are sequentially laid at the end of the roof, the heating cable 34 is located on the heat conduction pad 33, and the heating cable 34 is connected to the solar module 5 on the roof; among them, the flashing 35 is arranged below the eaves plug 31.

[0053] It should be noted that by setting the heating cable 34, i.e., the electric tracing band, at the upper eaves of the gutter, the melting of ice and snow at the upper eaves of the gutter in snowy and icy weather is realized, making it not easy to freeze and form "icicles" blocking the upper eaves of the gutter, resulting in the problem that the roof is not easy to drain water in rainy and snowy weather in time. At the same time, it can also avoid the sudden fall of the "icicles" and other shapes during melting, causing damage to the inside of the gutter. At the same time, in this device, the heating cable 34 is connected to the solar module 5 on the roof, a heat conduction pad 33 is arranged on the heating cable 34, and the heat conduction pad 33 is also arranged at the distance from the lower contact part of the heating cable 34 to the eaves, strengthening the heat and area generated by the heating cable 34. An insulation layer 32 is arranged at the distance from the eaves plug to the heating cable below the heat conduction pad 33 to avoid the temperature effect caused by the heat transferred by the heat conduction pad 33 affecting the lower structure. At the same time, the eaves plug 31 can prevent water droplets from seeping into the roof.

[0054] Referring to Figure 1 ,the solar module 5 includes a support beam 51, a roof panel 52 and a solar panel 53. The top of the roof 6 is connected to the roof panel 52 through the support beam 51. The support beam 51 can also be made of metal materials. The roof panel 52 can be made of aluminum-magnesium-manganese plate. Among them, the solar panel 53 is detachably installed on the top of the roof panel 52, and the solar panel 53 can provide energy for the heating cable 34 in the eaves snow melting and ice melting assembly 3, the tracing band in the gutter snow melting and ice melting assembly and the water pressure monitor 4.

[0055] Referring to Figure 7 and Figure 8 ,the gutter snow melting and ice melting assembly includes a gutter tracing band 71 and a "snake-shaped" groove opened on the heat conduction plate 12. The gutter tracing band 71 is laid in this "snake-shaped" groove, and the gutter tracing band 71 is connected to the solar module 5 on the roof. This method is to install a tracing band in the gutter for snow melting and ice melting by heating.

[0056] It should be noted that by opening a "snake-shaped" groove on the heat conduction plate and laying the gutter tracing cable 71 in the groove, the gutter tracing cable 71 also presents a "snake-shaped" structure, which can increase the coverage area of the tracing cable in the gutter 1 and solve problems such as small heat generation area coverage on the surface of the electric tracing cable in the gutter 1 and energy conservation. The heat conduction plate material can preferably be materials with good heat conduction performance such as metal and ceramic. This application can use fewer electric tracing cables to evenly generate a large area of heat to cover the entire gutter 1, and timely melt snow and ice in snowy and icy weather. If the area of the gutter 1 is small, the area ratio of the "snake-shaped" heat conduction plate can be appropriately reduced, and a "snake-shaped" groove can be arranged inside (as Figure 8 shown, what is given is a schematic diagram of opening a groove in the gutter and laying a tracing cable; and Figure 7 what is given is the situation of opening two grooves in the gutter and laying two tracing cables), specifically how many grooves are opened and how many tracing cables are set depend on the actual size of the gutter and the requirements on site. This application does not make a limitation here, and only two implementation methods are given. The purpose of this device is to use fewer electric tracing cables to generate a large area of heat on the gutter surface and achieve the effect of timely melting snow and ice on the basis of energy conservation.

[0057] Referring to Figure 9 , in another embodiment, the others are the same as above, the difference is that: the gutter snow melting and ice melting assembly includes an intelligent spraying part 72, and the intelligent spraying part 72 further includes a pipeline 721, a high-pressure nozzle 722, an automatic spraying control module 723 and a snowfall sensor 724. Among them, several high-pressure nozzles 722 are provided and are evenly laid on the side wall of the gutter 1. Several high-pressure nozzles 722 are connected through the pipeline 721. It should be noted that the specific number of high-pressure nozzles 722 is determined according to the size of the gutter and the actual installation situation. This application does not make a limitation here; the automatic spraying control module 723 and the snowfall sensor 724 are arranged at the end of the side wall of the gutter 1. One end of the pipeline 721 is connected to the deicing agent box body. The deicing agent is brine or snow melting agent. Under the control of the automatic spraying control module 723, the deicing agent in the deicing agent box body can be automatically transported into the pipeline 721, and then sprayed into the gutter by the high-pressure nozzle 722 to realize snow melting and ice melting in the gutter. This method is to install brine spraying or snow melting agent spraying in the gutter to realize snow melting and ice melting treatment. It should be noted here that the intelligent spraying scheme here is a reinforcement based on the heat conduction plate 12. The gutter tracing cable 71 can emit a large amount of heat on the heat conduction plate 12 to melt snow and ice, and the substances such as brine and snow melting agent sprayed by the intelligent spraying can also melt snow and ice, so as to enhance the snow melting effect in the gutter.

[0058] It should be noted that by setting the intelligent spraying member 72, it can remove snow in the gutter in winter and cool the gutter in summer. The pipeline 721 is installed on the inner walls on both sides at a distance of 0.1 - 0.3 m from the bottom of the gutter. The specific installation height depends on the on-site installation situation or the actual size of the gutter. This application does not make a limitation, and only gives a preferred range value for reference. The pipeline 721 of this application is also connected to a snowfall sensor 724 and an automatic spraying control module 723. The snowfall sensor 724 can sense the snowfall amount and temperature. When it snows in winter and the temperature is below 0°C, after the snowfall sensor 724 receives the signal, it controls the automatic spraying control module to spray snow melting agents, etc., and can also control the water spraying amount according to the snowfall amount. Especially when it suddenly snows in the middle of the night, the system will work immediately to prevent the snow from freezing in the gutter. In hot summer weather, it can be set to control the automatic spraying control module 723 within a certain temperature range to spray clean water for cooling, protect the components, and extend the service life. When this device melts and de-ices the gutter, it will not cause a temperature difference on the metal roof, and can effectively prevent the connection parts of the metal roof from leaking and becoming loose due to the temperature effect.

[0059] Refer to Figure 10 and Figure 11 , there is a roof machine box 11 inside the roof 6. The inside of the roof machine box 11 includes an inverter 111, an energy storage module 112, a load 113, a water pressure signal transmission module 114, and a heating control module 115 that are connected in sequence from top to bottom. Among them, the inverter 111 is connected to the solar panel 53. The inverter 111 converts the direct current generated by the solar panel 53 into alternating current. The energy storage module 112 is used for storing the electric energy converted by the inverter 111 and delivering the electric energy to the electrical load 113. The heating control module 115 controls the working state, heating time, and adjusts the temperature of each electric heating tape. The water pressure signal transmission module 114 is connected to the water pressure monitor 4, and the water pressure signal transmission module 114 is used to transmit the water pressure value in the gutter detected by the water pressure monitor 4. When the detected gutter water pressure value is abnormal, it is necessary to check and maintain in time.

[0060] The specific operation principle of this application is as follows: When encountering rainy or snowy weather, the rain and snow will flow along the roof and into the gutter 1 at the roof eave. Since the gutter 1 is concave, there is a certain height difference between its interior and the gutter eave. Therefore, ice cones may be formed at the upper eave during rainy or snowy weather. Therefore, an eave snow melting and de-icing assembly 3 is set to remove the ice cones. During the removal process, through the setting of the heating cable 34 and the heat conduction pad 33, snow melting and de-icing treatment at high temperature can be realized. The melted rainwater can flow into the gutter 1 from the flashing 35 under the action of the eave plug 31, thereby preventing ice cones from forming at the upper eave of the gutter;

[0061] However, the rainwater that falls into the gutter 1 still has a risk of freezing due to the low outdoor temperature environment, and the snow that falls into the gutter may accumulate. Since the gutter is at a high place and it is not easy for humans to remove it, a gutter snow melting and ice melting component is set in the gutter 1 to realize the snow melting and ice melting treatment inside the gutter 1. When specifically dealing with it, there are two optional methods. One is to realize snow melting and ice melting by setting a heating tape inside the gutter, and the other is to realize snow melting and ice melting by setting a snow melting agent spraying on the inner wall of the gutter;

[0062] When choosing to use a heating tape to realize snow melting and ice melting in the gutter, one gutter heating tape 71 (as shown in Figure 8 Figure) or two gutter heating tapes 71 (as shown in Figure 7 Figure) can be selected according to the size of the gutter 1 and the actual situation on site. The area ratio of the "snake-shaped" groove heat conducting plate can be appropriately reduced according to the size of the gutter 1 and the actual situation on site. A "snake-shaped" groove is set inside. In rainy and snowy weather, the gutter heating tape 71 diffuses heat through the "snake-shaped" groove heat conducting plate to cover the entire inside of the gutter 1 for heating, so as to be able to realize the snow melting and ice melting treatment of the snow or ice inside the gutter. After the snow and ice turn into rainwater, it can flow out from the siphonic rainwater hopper 2. When entering the siphonic rainwater hopper 2, the electric heating tape 10 in the rainwater pipe 9 also starts to work. The electric heating tape 10 is also controlled by the roof machine box 11. The electric heating tape 10 can prevent rainwater from freezing in the rainwater pipe 9 in a low temperature environment, and finally it can fall into the ground through the rainwater pipe 9. Among them, the electric heating tape 10 and the gutter heating tape 71 are powered by the solar panel 53;

[0063] When choosing to use the method of spraying snow melting agent to realize snow melting and ice melting, high-pressure nozzles 722 can be laid inside the gutter 1 according to the size of the gutter 1 and the actual situation on site. A plurality of high-pressure nozzles 722 are connected through a pipeline 721, and are connected to an automatic spraying control module 723 and a snowfall sensor 724. The inlet of the pipeline 721 is connected to an external snow melting agent box body. When in use, the automatic spraying control module 723 is controlled to work by the roof machine box 11. The automatic spraying control module 723 controls the snow melting agent in the snow melting agent box body to be input into the pipeline 721, and then sprays out from a plurality of high-pressure nozzles 722 into the inside of the gutter 1 and acts on the ice or snow inside the gutter 1, so as to realize the snow melting and ice melting treatment. After the snow and ice turn into rainwater, it can fall from the siphonic rainwater hopper 2. When entering the siphonic rainwater hopper 2, the electric heating tape 10 in the rainwater pipe 9 also starts to work. The electric heating tape 10 is also controlled by the roof machine box 11. The electric heating tape 10 can prevent rainwater from freezing in the rainwater pipe 9 in a low temperature environment, and finally it can fall into the ground through the rainwater pipe 9. Among them, the electric heating tape 10, the automatic spraying control module 723 and the snowfall sensor 724 are powered by the solar panel 53.
