DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] See also Figures 1 to 4 The utility model provides the following technical solutions: a construction engineering sand prevention device, comprising a sand prevention device body, the sand prevention device body comprising a reeling mechanism 1, a cleaning assembly 2, an auxiliary enclosure mechanism 3 and a filter membrane 4, a drive shaft 11 is built inside the reeling mechanism 1, one end of the filter membrane 4 is wound on the surface of the drive shaft 11, and a reeling box 17 is installed on the other end of the filter membrane 4, the two ends of the auxiliary enclosure mechanism 3 are respectively installed inside the reeling mechanism 1 and the reeling box 17, and a baffle 5 is connected in the middle of the auxiliary enclosure mechanism 3, the baffle 5 covers the bottom position of the filter membrane 4, and the bottom of the baffle 5 is in contact with the ground. The construction engineering sand prevention device is built in a vertical form in the construction site to prevent wind and sand.

[0024] When the utility model is used, the bottom of the reeling box 6 and the reeling box 17 in the reeling mechanism 1 are directly fixed on the ground, and after the two boxes are pulled apart as mentioned above, the middle filter membrane 4 is unfolded, and the wind and sand blown on one side can be enclosed by the unfolded filter membrane 4, so as to achieve the purpose of preventing wind and sand. In the process of long-term use, the removed filter membrane 4 can be controlled to be switched and updated by starting the motor 16, so as to quickly replace the filter membrane 4 part in the use state, thereby improving the effect of preventing wind and sand. In addition, the cleaning component 2 can be used to scrape and clean the reeled filter membrane 4 part. An additional auxiliary enclosure mechanism 3 is installed at the bottom of the device. Through the baffle 5 in the mechanism, the gap area between the bottom of the filter membrane 4 and the ground can be blocked, and the friction between the bottom of the filter membrane 4 and the ground can be avoided, thereby improving the protection effect of the filter membrane 4.

[0025] In this embodiment, the reeling mechanism 1 includes a reeling box 6 and a drive shaft 11. The top of the reeling box 6 is screwed with a motor 16. The output end of the motor 16 is plugged with a drive shaft 11. The end of the drive shaft 11 is keyed with a driving gear 12. The inside of the reeling box 17 is interspersed with a reeling rod 21. The filter membrane 4 passes through the inside of the reeling box 6 and the reeling box 17 respectively. The end of the filter membrane 4 is wound on the surface of the reeling rod 21. The two ends of the reeling rod 21 are embedded in the inner wall of the reeling box 17 through bearings. The bottom end of the drive shaft 11 is embedded in the inner wall of the reeling box 6 through bearings. The unfolding length of the middle filter membrane 4 can be regulated by the reeling mechanism 1 and the reeling box 17 at both ends, so the specific range of sand prevention can be adjusted, so that the device can be flexibly adjusted according to needs, expanding the scope of application, and the filter membrane 4 can be reeled in when not in use to avoid the phenomenon of surface clogging caused by long-term storage.

[0026] Specifically, after the reeling mechanism 1 is started, the motor 16 drives the driving shaft 11 to rotate, and the driving shaft 11 reels the filter membrane 4 part, that is, the filter membrane 4 part wound on the reeling rod 21 can be pulled out, and the pulled out filter membrane 4 part can be reeled onto the surface of the driving shaft 11, thereby realizing the renewal process of the external filter membrane 4 part, and this function can also be synchronously regulated as the distance between the reeling box 6 and the reeling box 17 changes, so that the range of sand prevention of the device can be flexibly regulated.

[0027] In this embodiment, the cleaning assembly 2 includes a dust box 7 and a roller brush 15. A driven shaft 14 is inserted into the interior of the dust box 7. The roller brush 15 is sleeved on the surface of the driven shaft 14. The bottom key of the driven shaft 14 is connected to a driven gear 13. The driving gear 12 and the driven gear 13 are meshed. A guide plate 8 is integrally formed on the inner wall of the dust box 7. A dust removal port 9 is provided on one side of the guide plate 8. An exhaust fan is installed inside the dust removal port 9. The side of the roller brush 15 is in contact with the surface of the filter membrane 4. During use, the filter membrane 4 can also be partially rolled up to achieve replacement of the filter membrane 4, ensuring that a high sand prevention effect can be maintained during long-term sand prevention use. In the process of switching, the filter membrane 4 is scraped and cleaned after use, reducing the difficulty of cleaning the filter membrane 4 later. Specifically, after starting the motor 16, the roller brush 15 is driven to rotate through the driving gear 12 and the driven gear 13, so that the part of the filter membrane 4 rolled into the reel box 6 can be wiped off with the help of the roller brush 15, and the impurities and dust attached to the surface of the filter membrane 4 during the sand prevention process can be brushed out to the outside, and the dust removal port 9 and the internal fan can be used to discharge the brushed dust to achieve the purpose of cleaning.

[0028] In this embodiment, the auxiliary enclosure mechanism 3 includes an adjustment box 18, a first rotating column 10, a second rotating column 19 and a baffle 5. The first rotating column 10 is embedded in the bottom of the inner side of the dust removal box 7, the second rotating column 19 is embedded in the bottom of the inner side of the adjustment box 18, and a hand wheel 20 is installed on the top of the second rotating column 19. The sides of the reeling box 6 and the unreeling box 17 are both provided with a first through-hole 22 and a second through-hole 23. The filter membrane 4 passes through the inside of the second through-hole 23, and the baffle 5 passes through the inside of the first through-hole 22. A baffle 5 structure is provided at the bottom. By providing the baffle 5 at the bottom of the filter membrane 4, the gap between the bottom of the filter membrane 4 and the ground can also provide a sand-proof effect, and the filter membrane 4 does not need to be directly in contact with the ground. The baffle 5 will not slide during the reeling process of the filter membrane 4, so that friction with the ground can be avoided. Specifically, the second rotating column 19 is driven to rotate by manually controlling the hand wheel 20, thereby changing the retracted length of the bottom baffle 5, so that the baffle 5 always covers the area at the bottom of the filter membrane 4, and the baffle 5 part will not move synchronously with the retracted process of the filter membrane 4, thereby avoiding contact and friction between the filter membrane 4 and the bottom ground, and avoiding a gap between the filter membrane 4 and the bottom ground.
