Description

Technical Field

[0002] The inflatable membrane structure is a new type of building structure and an important branch of lightweight space structure. It has rich and colorful shapes and excellent architectural and structural properties. It is mainly divided into tensile membrane structure, skeleton membrane structure, inflatable membrane structure, cable truss membrane structure, etc.

[0003] In the prior art, there is a snow melting device for air-film building roofs, such as the Chinese patent number CN219491519U, which includes an electric heating cable fitted with an air-film membrane material, an installation assembly, a snow depth sensor for monitoring the depth of snow on the surface of the air-film membrane material, and a controller for adjusting the heating temperature of the electric heating cable.

The snow depth sensor of the present application monitors the depth of snow accumulated on the air-film membrane material, and feeds back the monitoring data to the controller in real time. The controller supplies power to the electric heating cable, controls the temperature of the electric heating cable, and melts the snow, so that the snow melts into liquid water and flows to the ground along the outer wall of the air-film membrane material, thereby reducing the damage to the air film caused by snow accumulation on the surface of the air-film membrane material, reducing the load formed on the surface of the air-film membrane material by snow accumulation, and improving the problem that snow accumulation may cause damage to the air-film membrane material.

[0004] However, in the prior art, although the above patent has the above technical advantages, it has the disadvantage that when installing or repairing the snow-melting cable, the worker needs to tighten multiple bolts to remove the snow-melting cable. The bolts may be lost due to their small size, thereby increasing the construction cost, and repeatedly tightening the bolts may increase the workload of the workers. Utility Model Content

[0011] The beneficial effects of the utility model are as follows:

[0012] 1. The utility model provides a mounting plate. Since the pressure plate is rotatably connected to the mounting plate by a hinge, the staff can put the snow-melting cable into the arc groove of the pressure plate, and then rotate the fastening bolts threadedly connected to the mounting plate to make the fastening bolts descend a certain distance in the mounting plate, and the fastening bolts are stuck in the pressure plate. When the fastening bolts descend, the pressure plate is driven down to press the snow-melting cable. Before inspecting the snow-melting cable, the staff can rotate the fastening bolts to disengage them from the mounting plate, and then rotate the pressure plate to take out the snow-melting cable, which solves the problem that more bolts may be used in traditional devices, thereby increasing costs and increasing the work intensity of the staff.

[0013] 2. The utility model provides a dispersion device. When the staff adds the snow-melting agent into the fixed box, the driving motor can drive the rotating shaft to rotate. Then, as the rotating shaft rotates, the spiral blade can transport the snow-melting agent from the hollow tube upward to the space formed by the dispersion plate and the top cover. At this time, the plug rod and the fixed tube rotate with the top cover to break up the snow around the dispersion device. Then, the staff controls the driving motor to increase the speed. Then, the snow-melting agent instantly shakes violently on the dispersion plate and spills out from the small holes on the dispersion plate. At the same time, the slider on the fixed tube extends out of the fixed tube due to the centrifugal force generated by the rotation of the top cover. The connecting block slides on the fixed tube to prevent the slider from falling off the dispersion device. Then, the snow-melting agent on the dispersion plate can also be thrown out of the dispersion device from the fixed tube due to the centrifugal force. The scattered snow-melting agent melts the upper layer of snow, and the snow-melting cable melts the lower layer of snow. After the driving motor stops working, the contraction spring on the fixed block retracts the slider into the fixed tube through the connecting block, thereby solving the problem that when the lower layer of snow melts, large pieces of snow on the upper layer may fall from the roof and cause injuries to personnel.

[0026] Working principle:

[0027] When in use, the pressing plate 6 is rotatably connected to the mounting plate 5 by the hinge 7. The staff can put the snow-melting cable 4 into the arc groove of the pressing plate 6, and then rotate the fastening bolt 8 threadedly connected to the mounting plate 5 to make the fastening bolt 8 descend a certain distance in the mounting plate 5, and the fastening bolt 8 is stuck in the pressing plate 6. When the fastening bolt 8 descends, it drives the pressing plate 6 to descend, so that the pressing plate 6 presses the snow-melting cable 4; before inspecting the snow-melting cable 4, the staff can rotate the fastening bolt 8 to make it separate from the mounting plate 5, and then rotate the pressing plate 6 to take out the snow-melting cable 4.

[0028] The staff adds the snow-melting agent into the fixed box 10 on the top inner shell 3. When melting snow, the snow-melting cable 4 and the driving motor 11 work. The driving motor 11 can drive the rotating shaft 12 to rotate.

The connecting block 19 slides on the fixed tube 17 to prevent the slider 18 from falling off from the dispersing device 2. The deicing agent on the dispersing plate 15 can also be thrown out of the dispersing device 2 from the fixed tube 17 due to the centrifugal force. The scattered deicing agent melts the upper snow layer, and the snow-melting cable 4 melts the lower snow layer. This can prevent the upper large snow from falling off the top shell 1 after the lower snow layer melts. After the driving motor 11 stops working, the contraction spring 20 on the fixed block 21 retracts the slider 18 into the fixed tube 17 through the connecting block 19.
