Description

Technical Field

[0001] The utility model relates to the technical field of roof snow cleaning, and particularly relates to a high-rise roof snow cleaning device. Background Technique

[0002] Steel structure large flat roofs are widely popular at present. The large-area roofs of steel structure houses generally range from 5 to 15 meters above the ground, and have a gentle slope, which causes the snow to be not easily discharged. In areas such as Heilongjiang and Jilin, the snow on the roof can reach 1 meter thick. Especially continuous snowfall combined with low temperature will bring huge pressure to the roof load and is prone to cause collapse accidents.

[0003] The existing roof snow cleaning devices are usually installed on the roof. The linear module of the roof snow cleaning device drives the snow cleaning plate to push the snow away from the roof. Due to the volume limitation of the roof snow cleaning device itself, it can only clean the snow on a section of the roof targeted and cannot adapt to the large-area roofs of steel structure houses. During continuous snowfall, the snow cleaning device is also easily buried under the snow, resulting in the snow cleaning device being unable to work normally. And the bottom of the snow is easy to freeze, hindering the movement of the snow cleaning device on the roof. The conventional linear module cooperating with the scraper cannot remove the ice, thus resulting in the snow not being able to be cleaned in time.

[0004] To solve the above problems, a high-rise roof snow cleaning device is proposed. Summary of the Invention

[0013] Preferably, the ice removal component includes a fixing plate fixedly connected to the bottom of the housing, spring telescopic rods are symmetrically and fixedly connected to both sides of the bottom of the fixing plate respectively, a protection plate is fixedly connected to the bottom of the spring telescopic rods, a protruding groove is formed in the middle of the protection plate, a second sliding groove is formed in the fixing plate, a sliding seat is slidably connected inside the second sliding groove, a shoveling plate is fixedly connected to the bottom of the sliding seat, and a vibration motor is fixedly installed on the side of the shoveling plate.

[0014] As described above, the characteristics and advantages of a snow cleaning device for high-rise roofs in the present invention are:

[0015] By driving the telescopic rod to move left and right through the cooperation of the driving gear and the rack, the telescopic rod can drive the snow removal component and the ice removal component to move left and right, gradually moving from the middle of the roof to the edge of the roof, so as to realize the comprehensive cleaning of the snow on the roof, so that there will be no small-area residues on the roof after the snow removal component cleans, avoiding the situation that the roof is more likely to be damaged when the weight of the roof is uneven when snow accumulates again, and improving the safety of the steel structure house after snow cleaning.

[0016] It is extended through the cooperation of the telescopic rod and the bolt, enabling the telescopic rod to be connected in multiple sections to form different lengths. Thus, in the case of different specifications of steel structure houses, according to the moving stroke of the telescopic rod required for snow clearing work on the roof, the length formed by the telescopic rod can be adjusted, thereby better adapting to steel structure houses with different roof widths and improving the applicability of the device.

[0017] Through the transmission connection between the rotary brush and the reciprocating lead screw, when the rotary brush rotates to clean the snow, the driving pulley, belt, and driven pulley on one side of the housing drive the reciprocating lead screw to rotate. Thus, under the action of the connecting block, the scraper is driven to reciprocate on the inner wall of the housing. During the moving process, the scraper scrapes off the snow adhering to the inner wall of the housing, preventing excessive snow accumulation inside the housing from affecting the rotation of the rotary brush and ensuring the stable operation of the device.

[0018] Through the cooperation of the pop-up groove and the shovel plate, when encountering frozen snow surface, while the protective plate is blocked and stops moving, it squeezes the spring telescopic rod, causing the shovel plate to extend out of the groove. Under the cooperation of the vibration motor and the second sliding groove, the teeth at the bottom of the shovel plate break the frozen part, and it can also have a certain effect of dispersing the initially solidified snow, contributing to the snow clearing efficiency of the snow clearing component and avoiding the situation where the elastic rotary brush cannot clean the ice, improving the cleaning effect of the device.

Support rubber wheels 510 are fixedly installed on both sides of the housing 501. The support height of the support rubber wheels 510 is higher than the roof, so that there is a certain distance between the snow removal component and the roof, preventing damage to the roof when the rotary brush 502 rotates.

[0038] Further, as Figure 1 、 Figures 8 to 10As shown in the figure, an ice removal component is provided at the bottom of the snow removal component. The ice removal component includes a fixing plate 601 fixedly connected to the bottom of the housing 501. On both sides of the bottom of the fixing plate 601, spring telescopic rods 602 are symmetrically and fixedly connected respectively. The bottom end of the spring telescopic rod 602 is fixedly connected to a protection plate 603. A protruding groove 604 is formed in the middle of the protection plate 603. A second sliding groove 605 is formed inside the fixing plate 601. A sliding seat 606 is slidably connected inside the second sliding groove 605. The width of the second sliding groove 605 is slightly larger than that of the sliding seat 606, so that the sliding seat 606 has a certain moving space when vibrating. A shovel plate 607 is fixedly connected to the bottom of the sliding seat 606, and the shovel plate 607 is inclined. A vibration motor 608 is fixedly installed on the side of the shovel plate 607.

[0039] Combined with the above preferred embodiments, the following is the entire working process and working principle of the above embodiments:

[0040] The initial state is:

[0041] The middle part of the telescopic rod 4 is located at the inner center of the base 2. The lengths of the telescopic rods 4 on both sides of the base 2 are equal. The second pneumatic motor 511 is not started. The slider 505 and the scraping plate 506 are located at one end of the reciprocating lead screw 504 inside the fixed cover 503. The snow removal component and the ice removal component are located above the roof and above the surface of the accumulated snow. The protection plate 603 is not in contact with the snow surface or the ice surface. The spring telescopic rod 602 is in an extended state without being squeezed by the protection plate 603. The bottom of the shovel plate 607 is located inside the protruding groove 604 and does not exceed the bottom opening of the protruding groove 604. The vibration motor 608 is not powered on, so that the sliding seat 606 is stationary inside the second sliding groove 605, and the sliding seat 606 makes the shovel plate 607 stationary inside the protruding groove 604.

[0042] The working state is:

[0043] The snow removal personnel adjust the telescopic rod:

[0044] Both ends of the telescopic rod 4 can be connected and assembled by bolts. The snow removal personnel can initially measure the width of the roof to be cleared of snow, and then adjust the length formed by multiple telescopic rods 4 by disassembling and assembling the bolts, so that its length is greater than the width of the roof. Thus, when the telescopic rod 4 moves left and right, the moving range of the snow removal component and the ice removal component can cover the roof, so as to achieve the snow removal effect on the entire roof, avoid the situation that there is still residual snow in some positions of the roof, and there is no need for secondary cleaning after snow removal, improving the efficiency of roof snow removal work and being more convenient at the same time;

[0045] The snow removal component sweeps the large-area snow on the roof:

[0046] When performing snow clearing work, the second pneumatic motor 511 is started, so that the second pneumatic motor 511 drives the roller brush 502 to rotate. When the roller brush 502 rotates, the accumulated snow is scattered and brought into the housing 501. The snow discharge pipe 509 and the fan inside the snow discharge pipe 509 cooperate to discharge the scattered snow, so that the snow is discharged outside the roof to prevent the scattered snow from accumulating with the uncleaned snow. When the roller brush 502 rotates, it drives the driving pulley 512 on the other side to rotate, and the driving pulley 512 drives the driven pulley 51 through the belt 513. 4 rotates, the driven pulley 514 drives the reciprocating screw 504 inside the fixed cover 503 to rotate, the reciprocating screw 504 drives the slider 505 to move back and forth inside the fixed cover 503 through the thread, the slider 505 drives the connecting block 508 to move synchronously in the first sliding groove 507, and synchronously drives the scraper 506 to move back and forth on the inner wall of the shell 501, and the scraper 506 scrapes off the snow adhering to the inner wall of the shell 501 when reciprocating, so as to prevent the snow inside the shell 501 from solidifying and affecting the rotation of the roller brush 502.

[0047] The de-icing kit removes frozen snow:

[0048] When the lifting vehicle at the bottom of the device drives the column 1 to descend, it will drive the snow-clearing components on both sides of the device to descend. When the snow-clearing components come into contact with the snow surface, the de-icing components at the bottom of the snow-clearing components will first come into contact with the snow surface. When the snow is frozen, the protective plate 603 at the bottom of the de-icing components will first come into contact with the ice surface. Since the ice surface has a certain hardness, when the protective plate 603 comes into contact with the ice surface, the protective plate 603 will move upward, squeezing the spring telescopic rod 602 while making the bottom of the shovel plate 607 extend out of the protruding groove 604, so that the protective plate 603 03 contacts the ice, and the vibration motor 608 is started. The sliding seat 606 on the top of the shovel plate 607 has a certain movable space inside the second sliding groove 605, so that the shovel plate 607 can vibrate in the protruding groove 604, and cooperate with the teeth at the bottom of the shovel plate 607 to break the ice, and can also preliminarily break up the slightly solidified snow. At the same time, the vibration can resonate with the roof, which can weaken the adhesion of the snow on the roof, and can make part of the snow slide off the roof by itself, so as to facilitate the subsequent snow clearing operation of the snow clearing assembly, such as Figure 8 As shown, the surface of the bottom teeth of the shovel plate 607 is provided with rubber wrapping to prevent damage to the roof;

[0049] The telescopic rod drive assembly drives the snow removal assembly to move snow on the roof:

[0050] When the first pneumatic motor 302 starts to drive the worm 303 to rotate, the worm 303 drives the worm wheel 304 to rotate. The worm wheel 304 drives the driving gear 305 coaxial with it to rotate. The driving gear 305 cooperates with the rack 307 inside the telescopic rod 4 to drive the telescopic rod 4 to move left and right. When the first pneumatic motor 302 drives the telescopic rod 4 to extend to one side of the roof and synchronously moves the snow clearing assembly to the side of the roof far from the device, at this time, the snow clearing assembly is higher than the snow surface of the snow accumulation. After the lifting vehicle descends and the snow clearing assembly contacts the snow surface and starts to clear the snow, the first pneumatic motor 302 drives the worm wheel 304 to rotate in the direction opposite to that when driving the telescopic rod 4 to extend, so that the telescopic rod 4 drives the snow clearing assembly to move towards the side of the roof, thereby achieving the snow clearing effect of covering the roof.

[0051] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
