Description

Technical Field

[0001] The invention relates to the technical field of roof snow melting, and in particular to a roof snow melting line mechanism which is convenient for retracting and releasing the line. Background Art

[0002] In rainy and snowy weather in winter, large areas of snow and even ice often accumulate on the roof. Due to the low temperature, the ice and snow on the roof are not easy to melt and accumulate on the roof for a long time. When the ice and snow accumulated on the roof exceeds the load-bearing capacity of the roof, it is easy for large pieces of ice and snow to slide from the roof. If pedestrians pass under the eaves of the roof, it is easy to cause injuries to pedestrians.

[0003] Nowadays, in some areas with lower temperatures, electric snow melters are often installed on roofs to accelerate the melting of ice and snow and prevent excessive accumulation of ice and snow on the roofs. However, existing electric snow melters are mostly single snow melting cables laid on the roofs, which are heated by electricity to melt snow. However, the cables are exposed to the air for a long time, and the accumulated water when the ice and snow melt will accelerate the aging of the cable sheath and reduce the service life of the snow melting cable. In addition, in windy weather, the cable is easily blown by the wind, and then rubbed against the fixed bracket or bent at a large angle, thereby damaging the cable sheath and causing short circuits when the electric snow melter is heating to melt snow. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides the following technical solutions: a roof snow melting line mechanism which is convenient for retracting and releasing the line, comprising a roof, and an installation frame fixedly installed on the top of the roof, a retracting and releasing assembly is arranged on one side of the installation frame, a screw rod is rotatably connected to the inner wall of the installation frame, a threaded block is screwed on the screw rod, a fixing seat is fixedly connected to the bottom of the threaded block, a reeling net is installed inside the fixing seat, and a plurality of heating cables are inserted and installed inside the reeling net.

[0010] Preferably, a support rod is fixedly connected to the inner wall of the installation frame, a connecting block is sleeved on the support rod, and the bottom of the connecting block is fixedly connected to one side of the top of the fixing seat.

The reeling net 7 is installed, and then the mounting frame 2 is fixedly installed on the roof 1, thereby improving the stability of the heating cable. After the snow melts, the reeling net 7 is reeled in by the reeling assembly 3, and the screw rod 4 is driven to rotate. The rotation of the screw rod 4 drives the threaded block 5 to move, and the threaded block 5 drives the fixing seat 6 to move, thereby putting the reeling net 7 into the reeling assembly 3, protecting the heating cable on the reeling net 7, and facilitating the release and retraction of the heating cable, which has the effect of quickly installing and disassembling the heating cable.

[0030] In the specific implementation process, Figure 2 As shown, the retractable assembly 3 includes a cylinder 31 connected to one side of the mounting frame 2, a motor 32 is fixedly connected to one side of the cylinder 31, a first bevel gear 33 is fixedly connected to the output end of the motor 32, a rotating shaft 34 is fixedly connected to the axis of the first bevel gear 33, a second bevel gear 35 is meshingly connected to the outer side of the first bevel gear 33, and a limiting disk 36 is fixedly connected to one end of the rotating shaft 34.

The bottom of the connecting block 16 is fixedly connected to one side of the top of the fixed seat 6. When the fixed seat 6 moves in the installation frame 2, the connecting block 16 slides on the support rod 15 to guide and limit one side of the fixed seat 6, thereby improving the stability of the fixed seat 6 when moving.

[0038] The bottom of the threaded block 5 and the connecting block 16 are fixedly connected with a slider 17, and the inner wall of the mounting frame 2 is provided with a slide groove 18 used in conjunction with the slider 17.
