[0074] The air film 50 snow removal device and the air film 50 building according to the embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0075] Reference Figures 1 to 3 As shown, the air film 50 snow removal device provided according to an embodiment of the present invention is suitable for scraping off the snow on the top of the air film 50, and includes a snow scraping rod assembly 10, a sliding mechanism 20, a first traction device 30 and a second traction device 31.

[0076] Specifically, the snow scraper rod assembly 10 extends in the longitudinal direction of the air film 50 . For example, the length direction of the air film 50 may be the longitudinal direction, and the width direction of the air film 50 may be the transverse direction.

[0077] The sliding mechanism 20 includes a plurality of sliding vehicles 201 and a plurality of groups of pull ropes. The plurality of sliding vehicles 201 are arranged on the snow scraper rod assembly 10 at longitudinal intervals along the air film 50. The bottom of each sliding vehicle 201 has rolling wheels. The contact between the rolling wheels and the surface of the air film 50 can reduce the wear on the air film 50 and facilitate the movement of the sliding vehicle 201 on the surface of the air film 50. The sliding vehicle 201 then drives the snow scraper rod assembly 10 to move on the surface of the air film 50 to scrape off the snow on the surface of the air film 50.

[0078] The plurality of pull ropes correspond to the plurality of sliding vehicles 201 one by one, and each pull rope comprises a first pull rope 202 and a second pull rope 203, wherein the upper end of the first pull rope 202 is connected to the sliding vehicle 201, and the other end of the first pull rope 202 extends to one side along the lateral direction of the air film 50, and the upper end of the second pull rope 203 is connected to the sliding vehicle 201, and the other end of the second pull rope 203 extends to the other side along the lateral direction of the air film 50. In other words, the first pull rope 202 and the second pull rope 203 are respectively located on both sides of the lateral direction of the sliding vehicle 201, and the upper ends of the first pull rope 202 and the second pull rope 203 are both connected to the sliding vehicle 201.

[0079] The first traction device 30 is arranged on one lateral side of the air membrane 50 and is connected to the other end of each of the first pull ropes 202. The second traction device 31 is arranged on the other lateral side of the air membrane 50 and is connected to the other end of each of the second pull ropes 203, so as to release or shorten the first pull rope 202 and the second pull rope 203 through the first traction device 30 and the second traction device 31, thereby driving the snow scraper rod assembly 10 to reciprocate laterally along the air membrane 50.

[0080] During the specific working process, when the first traction device 30 shortens the first pull rope 202 and the second traction device 31 releases the second pull rope 203, the sliding vehicle 201 slides to one side under the pulling force of the first pull rope 202, thereby driving the snow scraper rod assembly 10 to slide to one side. When the second traction rope shortens the second pull rope 203 and the first traction device 30 releases the first pull rope 202, the sliding vehicle 201 slides to the other side under the pulling force of the second pull rope 203, thereby driving the snow scraper rod assembly 10 to slide to the other side. In this way, the first traction device 30 and the second traction device 31 work alternately to drive the snow scraper rod assembly 10 to reciprocate laterally along the air film 50, thereby scraping off the snow on the top of the air film 50.

[0081] According to the air membrane 50 snow removal device and air membrane 50 building provided in the embodiment of the present invention, the first traction device 30 and the second traction device 31 can release or shorten the first pull rope 202 and the second pull rope 203, thereby driving the snow scraper rod assembly 10 to reciprocate along the lateral direction of the air membrane 50. The snow scraper rod assembly 10 reciprocates on the top of the air membrane 50 to remove the accumulated snow on the top of the air membrane 50, and the snow removal effect is good and the efficiency is higher.

[0082] Optionally, there are multiple snow scraper rod assemblies 10 , which are sequentially arranged along the longitudinal direction of the air film 50 , and adjacent ends of two adjacent snow scraper rod assemblies 10 are fixedly mounted on the same sliding vehicle 201 .

[0083] That is to say, the two ends of each snow scraper rod assembly 10 are respectively connected to two sliding carts 201, and the adjacent ends of two adjacent snow scraper rod assemblies 10 are fixed to one sliding cart 201. In this way, multiple sliding carts 201 can be used to support each snow scraper rod assembly 10, ensuring that the snow scraper rod assembly 10 is installed reliably and slides more smoothly on the surface of the air film 50.

[0084] In some embodiments of the present invention, the snow scraper bar assembly 10 includes a scraper bar seat 101, a floating scraper bar 102 and an elastic member 103, wherein the scraper bar seat 101 extends in the longitudinal direction of the air film 50, and the two ends of the scraper bar seat 101 are respectively fixed on the two sliding vehicles 201. The floating scraper bar 102 is slidably mounted on the bottom of the scraper bar seat 101 in the up and down directions. The elastic member 103 is arranged between the scraper bar seat 101 and the floating scraper bar 102, and when the floating scraper bar 102 moves upward, the elastic member 103 is compressed.

[0085] That is, the snow scraper bar assembly 10 is mainly composed of a scraper bar seat 101, a floating scraper bar 102 and an elastic member 103. The two ends of the scraper bar seat 101 are fixedly mounted on the sliding vehicle 201, and the floating scraper bar 102 is mounted on the bottom of the scraper bar seat 101 and can slide up and down. The elastic member 103 is located between the scraper bar seat 101 and the floating scraper bar 102. In some cases, the snow on the surface of the air film 50 may freeze to form hard blocks with high hardness and unevenness. In this case, the snow scraper bar assembly 10 is easy to be damaged or even stuck when it contacts these hard blocks. In this embodiment, the snow scraper rod assembly 10 with the above-mentioned structure is adopted. When the floating scraper bar 102 contacts a protruding block with high hardness, the floating scraper bar 102 is acted upon by the block and floats upward, thereby ensuring that the floating scraper bar 102 can scrape over the block without getting stuck or damaging the floating scraper bar 102. After scraping over the block, the elastic member 103 forces the floating scraper bar 102 to quickly reset. In this way, the snow scraper assembly is not easily damaged and will not get stuck easily, and the snow scraping operation is more stable and reliable. In addition, the blocks can be gradually scraped off by reciprocating motion multiple times, and the snow removal effect is good.

[0086] In one embodiment of the present invention, the scraper seat 101 includes a fixing seat 101a and a cover plate 101b, wherein the fixing seat 101a has a mounting groove penetrating in the up and down directions, and the inner wall of the mounting groove has a step surface S101, and the cover plate 101b can be detachably installed on the top of the fixing seat 101a to close the mounting groove.

[0087] The floating scraper 102 includes a floating seat 102a and a scraper 102b. The floating seat 102a can be slidably inserted into the mounting groove, and the two ends of the floating seat 102a are provided with stop shoulders 1021, and the stop shoulders 1021 stop above the step surface S101. The scraper 102b is detachably installed at the bottom of the floating seat 102a and extends along the longitudinal direction of the air film 50. The two ends of the fixed seat 101a or the cover plate 101b are respectively fixed on the two sliding vehicles 201. When the scraper 102b contacts the block, the scraper 102b moves upward under the action of the block, and the floating seat 102a slides upward in the fixed seat 101a, thereby compressing the elastic member 103.

[0088] In this embodiment, the scraper seat 101 and the floating scraper 102 of the above-mentioned structure are adopted, which is convenient for assembly, and the floating seat 102a and the fixed seat 101a are matched through the step surface S101 and the stop shoulder 1021, so that the floating seat 102a and the fixed seat 101a can slide between them without falling off. In addition, the scraper 102b and the floating seat 102a are detachably connected, which is convenient for the replacement of the scraper 102b.

[0089] Advantageously, the elastic member 103 includes a plurality of compression springs, a plurality of guide posts 1011 are provided at the bottom of the cover plate 101b, a plurality of guide holes H102 are provided at the top of the floating seat 102a, the plurality of guide posts 1011 correspond one-to-one to the plurality of guide holes H102, each of the guide posts 1011 is slidably fitted with the corresponding guide hole H102, the plurality of compression springs correspond one-to-one to the plurality of guide posts 1011, each of the compression springs is sleeved on the corresponding guide post 1011, and the upper end of the compression spring abuts against the cover plate 101b, and the lower end of the compression spring abuts against the floating seat 102a.

[0090] In this way, the elastic action of multiple compression springs can ensure that the elastic action force received by the floating seat 102a is more uniform, and then the floating is reliable. In addition, the cooperation of the guide column 1011 and the guide hole H102 can make the floating seat 102a move up and down more smoothly.

[0091] In one embodiment of the present invention, the sliding vehicle 201 has a hanging ring 201a and 201b at both ends of the air film 50 in the lateral direction; the upper end of the first pull rope 202 has a first locking hook 2021, and the upper end of the second pull rope has a second locking hook 2031. The first locking hook 2021 is hung on the hanging ring 201a at one end of the sliding vehicle 201, and the second locking hook 2031 is hung on the hanging ring 201b at the other end of the sliding vehicle 201. During the construction and installation process, the first locking hook 2021 on the first pull rope 202 can be hung on the hanging ring 201a at one end of the sliding vehicle 201, and the second locking hook 2031 on the second pull rope 203 can be hung on the hanging ring 201b at the other end of the sliding vehicle 201. In this way, the installation is simpler and more convenient, and it is easy to maintain.

[0092] In one embodiment of the present invention, the first traction device 30 includes a first reel 302 and a first drive motor 301. The first reel 302 is pivotally arranged on one side of the lateral direction of the air film 50 around its own axis. The first drive motor 301 is connected to the first reel 302 to drive the first reel 302 to rotate. The second traction device 31 includes a second reel 312 and a second drive motor 311. The second reel 312 is pivotally arranged on one side of the lateral direction of the air film 50 around its own axis. The second drive motor 311 is connected to the second reel 312 to drive the second reel 312 to rotate. The other ends of the plurality of first pull ropes 202 are fixedly connected to the first reel 302, and the other ends of the plurality of second pull ropes 203 are fixedly connected to the second reel 312.

[0093] In this embodiment, the first drive motor 301 drives the first reel 302 to wind up the first pull rope 202 to shorten it, or releases the first pull rope 202 to lengthen it, and the second drive motor 311 drives the second reel 312 to wind up the second pull rope 203 to shorten it, or releases the second pull rope 203 to lengthen it. In this way, the reciprocating motion of the snow scraper rod assembly 10 can be achieved, and its structure is simple and the driving is reliable and stable.

[0094] In some embodiments of the present invention, a detection sensor and a controller are also included. The detection sensor is used to detect snow accumulation on the air film 50. The controller is connected to the detection sensor and the first traction device 30 and the second traction device 31 to control the operation of the first traction device 30 and the second traction device 31 according to the signal of the detection sensor. For example, when the detection sensor detects snow accumulation, for example, the thickness of the snow reaches a predetermined value, the controller controls the operation of the first traction device 30 and the second traction device 31 to realize automatic snow removal.

[0095] In one embodiment of the present invention, two centering positioning mechanisms are further included, and the two centering positioning mechanisms are respectively located at two ends of the longitudinal direction of the air film.

[0096] Each of the centering positioning mechanisms includes a cable reel 71, a fixed cable 70 and a rotating elastic member. The cable reel is arranged on one side of the longitudinal direction of the air membrane and can pivot around its own axis. One end of the fixed cable 70 is connected to one of the sliding vehicles at one end of the sliding mechanism, and the other end of the fixed cable 70 is fixed to the cable reel 71 so that the fixed cable 70 can be wound around the cable reel 71. The rotating elastic member is connected to the cable reel 71 to provide an elastic rotating force so that the cable reel 71 rotates in one direction to tighten the fixed cable 70.

[0097] In this embodiment, a centering positioning mechanism is respectively arranged on both sides of the longitudinal direction of the air membrane, and the centering positioning mechanism is mainly composed of a cable reel 71, a fixing cable 70 and a rotating elastic member, wherein the cable reel 71 can be installed on the bottom surface or building foundation of one side of the longitudinal direction of the air membrane, and the cable reel 71 can rotate around its own axis, and the fixing cable 70 is connected between the sliding vehicle and the cable reel 71. In addition, the rotating elastic member can provide a rotational elastic force for the cable reel 71. When there is no other external force involved, the rotational elastic force provided by the rotating elastic member can force the cable reel 71 to rotate in one direction, thereby winding the fixing cable 70 on the cable reel 71, so that the fixing cable 70 remains taut.

[0098] Since the sliding mechanism slides back and forth laterally along the air film during the snow-clearing process, at this time, the fixed rope 70 is stretched by the pulling force of the sliding mechanism, and the rope wheel rotates in the other direction (opposite direction), thereby releasing the fixed rope 70, so that the fixed rope 70 can freely stretch or shorten with the sliding of the sliding mechanism. Finally, when the snow-clearing stops, under the action of the rotational elastic force, the rope wheel 71 winds up the fixed rope, so that the fixed rope pulls the sliding mechanism to the laterally centered position on the top of the air film. In this way, the rotational elastic force can be used to make the reciprocating sliding of the sliding mechanism smoother and more reliable, and the sliding mechanism can also be reset and kept centered after use.

[0099] Reference Figure 1 As shown, the air film 50 building according to the embodiment of the present invention has the air film 50 snow removal device as described above.

[0100] It can be understood that the air membrane 50 building of the embodiment of the present invention also includes a building foundation 60, an air membrane 50, etc. The lower edge of the air membrane 50 is fixed and sealed on the building foundation 60.
