Description

Technical Field

[0001] The utility model belongs to the technical field of roof snow melting, in particular to a roof anti-icing and snow melting device. Background Art

[0002] The roof blocks rain and snow and protects the indoor environment. In cold areas in winter, especially in the northern areas with severe cold climates, there are usually several heavy snowfalls in winter. In addition, the external ambient temperature is low in winter, and the natural melting effect of snow is poor, resulting in snow accumulation for a long time, and even snowfall again before the snow melts. As the snow accumulates, the weight of the snow will increase the load on the roof. If the amount of snow exceeds the load limit of the building, it will cause the structure of the building roof to change, and even cause the building to collapse.

[0003] At present, snow on building roofs is mainly cleared manually. However, due to the particularity of the shape and roof structure of some large buildings, such as the sloping roof structure, climbing onto the roof to clear snow is not only difficult but also poses a great safety hazard.

DETAILED DESCRIPTION

[0032] The roof anti-icing and snow-melting device of the utility model is further described in detail below in conjunction with the accompanying drawings and specific embodiments:

[0033] like Figure 1As shown, the roof anti-icing and snow-melting device of the utility model includes a concrete base 3, which is located below the roof structure. The concrete base 3 forms an inclined slope roof with a high middle and low front and back. The high middle part forms a ridge 1, and the low front and back parts form an eaves 2. A mounting plate 4 is relatively fixed above the concrete base 3. The size of the mounting plate 4 corresponds to the concrete base 3, and a heating pipe network is fixed on the mounting plate 4. A heat-conducting layer 12 is fixed above the heating pipe network. The heat-conducting layer 12 is used to conduct the heat of the heating pipe network so that the heat on the heating pipe network can be more evenly dispersed. A concrete layer 13 is laid above the heat-conducting layer 12, and a roof decoration layer 14 is laid above the concrete layer 13 to ensure the aesthetics of the roof structure. In the utility model, the heating pipe network is located in the roof structure, and the heat emitted by the heating pipe network can diffuse upward to the roof to melt the snow on the roof. In this embodiment, the structure and heat-conducting principle of the heat-conducting layer 12 belong to the prior art and will not be repeated here.

[0034] In this embodiment, in order to prevent the heat of the heating pipe network from spreading to the bottom of the roof structure, a heat insulation layer 9 is fixed above the concrete base 3, and the heat insulation layer 9 forms a heat insulation barrier in the middle of the roof structure to prevent the heat of the heating pipe network in the roof structure from spreading up and down; in this embodiment, the structure and heat insulation principle of the heat insulation layer 9 belong to the prior art and will not be repeated here. The heat insulation layer 9 is located below the mounting plate 4 and has a size corresponding to the mounting plate 4.

[0035] Specifically, the heating pipe network includes an inlet pipe 5 arranged at the eaves 2 of the inclined slope roof, an outlet pipe 6 arranged at the ridge 1 of the inclined slope roof, and a plurality of connecting pipes 7 connecting the inlet pipe 5 and the outlet pipe 6. The inlet pipe 5 is arranged horizontally in the left-right direction, the outlet pipe 6 is extended in the left-right direction, and the connecting pipe 7 is an inclined pipe arranged from the ridge 1 to the eaves 2 and from top to bottom. The circulating medium in the heating pipe network is hot water heated by an electric heater.

[0036] The left end of the water inlet pipe 5 is connected to the electric heater, that is, the left end of the water inlet pipe 5 forms the water inlet end of the water inlet pipe 5, and the right end of the water inlet pipe 5 is blocked; the right end of the water outlet pipe 6 is connected to the electric heater, that is, the right end of the water outlet pipe 6 forms the water outlet end of the water outlet pipe 6, and the left end of the water outlet pipe 6 is blocked. In this embodiment, the structure and heating principle of the electric heater are prior art and will not be described in detail here. In this embodiment, the electric heater is connected to the water supply network (not shown in the figure).

[0037] In this embodiment, the hot water in the heating pipe network gradually flows from the lower eaves 2 of the sloping roof to the higher ridge 1. The hot water flows slowly, which increases the heat exchange time between the hot water in the heating pipe network and the ice and snow on the ridge 1, so that the hot water in the heating pipe network can fully exchange heat with the ice and snow on the roof. In addition, the temperature near the eaves 2 in the heating pipe network is relatively high, and the temperature near the ridge 1 is relatively low, so that the ice and snow at the eaves 2 melt first, and the melted snow water can be smoothly discharged from the roof, which is convenient for the flow of snow water after the subsequent snow melting on the roof. Therefore, the snow melting device has a better snow melting effect.

[0038] In order to facilitate the fixed installation of the heating pipe network, in this embodiment, a mounting hole is opened on the mounting plate 4, and the heating pipe network is fixed on the mounting plate 4 through a connector 8 connected to the mounting hole. In this embodiment, the connector 8 is in a "F" shape, including a first ear plate 15, a second ear plate 16, and a clamping portion connected between the first ear plate 15 and the second ear plate 16, and the connecting pipe 7 is located in the clamping portion, so as to limit the connecting pipe 7 through the clamping portion. Specifically, the clamping portion includes a first vertical plate 17 fixedly connected to the first ear plate 15, a second vertical plate 18 fixedly connected to the second ear plate 16, and a horizontal support plate 19 fixed between the first vertical plate 17 and the second vertical plate 18. The distance between the first vertical plate 17 and the second vertical plate 18 is equal to the diameter of the connecting pipe 7, and the height of the horizontal support plate 19 from the ear plate is equal to the diameter of the connecting pipe 7. After the connector 8 is fixed on the mounting plate 4, the connector 8 limits the connecting pipe 7 of the heating pipe network in the left and right directions and the up and down directions. The first ear plate 15 and the second ear plate 16 are respectively provided with through holes corresponding to the mounting holes on the mounting plate 4 , so as to facilitate the connection and fixation of the connecting member 8 and the mounting plate 4 .

[0039] In order to prevent the structure above the heating pipe network from squeezing the heating pipe network, in this embodiment, a support network 10 is fixed above the heating pipe network, the horizontal support plate 19 of the connecting member 8 provides a fulcrum for the support network 10, and the heat conductive layer 12 is arranged above the support network 10. In this way, the multiple connecting members 8 provide a plurality of support points for the support network 10, thereby ensuring the stability of the support network 10 and enabling the support network 10 to withstand a large load.

[0040] Specifically, the support mesh 10 includes steel bars that intersect vertically and horizontally, and the connector 8 is arranged corresponding to the intersection of the steel bars of the support mesh 10. A connecting hole is provided on the horizontal support plate 19, and a connecting plate 11 is provided above the intersection of the steel bars corresponding to the support mesh 10 and the connector 8. A through hole is provided on the connecting plate 11 corresponding to the connecting hole, and the connecting plate 11 is connected to the horizontal support plate 19 through a fastener adapted to the connecting hole. In this embodiment, the connecting hole is a blind hole with an internal thread and an opening facing upward, and the fastener is a screw. The support mesh 10 can be fixed relative to the connector 8 by the connecting plate 11, the screw, and the connector 8 to prevent the support mesh 10 from being displaced. The setting of the support mesh 10 transforms the point support of the roof structure by the connector 8 on the fixed installation plate 4 into the surface support of the connector 8 to the support mesh 10, and the support stability is better.

[0041] In the above embodiment, the clamping portion includes a first vertical plate fixedly connected to the first ear plate, a second vertical plate fixedly connected to the second ear plate, and a horizontal support plate fixed between the first vertical plate and the second vertical plate; in other embodiments, the clamping portion includes a first vertical plate fixedly connected to the first ear plate, a second vertical plate fixedly connected to the second ear plate, and an arc-shaped connecting plate fixed between the first vertical plate and the second vertical plate.

[0042] In the above embodiment, a support net is fixedly arranged above the heating pipe net, the horizontal support plate of the connecting member provides a fulcrum for the support net, and the heat conductive layer is arranged above the support net. In other embodiments, the support net may not be arranged.

[0043] In the above embodiments, a heat insulating layer is provided between the concrete base and the mounting plate; in other embodiments, the heat insulating layer may not be provided.

[0044] In the above embodiment, the left end of the water inlet pipe is connected to the electric heater, and the right end of the water outlet pipe is connected to the electric heater; in other embodiments, the right end of the water inlet pipe is connected to the electric heater, and the left end of the water outlet pipe is connected to the electric heater.
