Description

Technical Field

[0001] The invention relates to the technical field of dust reduction in building construction, and in particular to a dust reduction device for intelligent building engineering construction. Background Art

[0002] With the continuous development of urban construction, the scale and number of intelligent building projects are increasing. Some construction sites are located around urban residential areas, and the construction of construction sites is inseparable from sand, cement and soil. In the process of use, a large amount of dust and pollutants will inevitably be generated. These fine dusts will drift in the air with the wind, thus threatening the health of construction workers. If they spread outward, they will pollute the city's environment and affect the lives of surrounding residents. Therefore, dust and other dusts need to be treated through dust suppression devices.

[0003] Dust suppression devices cannot do without water. Currently, most dust suppression devices are supplied with tap water, circulating water, etc. When the tap water, circulating water, etc. are in short supply and the water source is not clear enough, it is easy to cause the spray head in the dust suppression device to be blocked, causing the dust suppression device to fail to work properly. In addition, the position of the spray head in the existing dust suppression device is mostly fixed and cannot be adjusted according to the actual usage scenario. As a result, during the spray dust removal process, all areas that need to be sprayed cannot be covered. The spray position often needs to be adjusted multiple times. At the same time, the spray direction is fixed and cannot be adjusted according to actual needs, resulting in poor spraying effect. Summary of the invention

[0017] The beneficial effects of the present invention are:

[0018] 1. Adjust the position of the spray pipe as needed. The inclination angles of multiple spray pipes can be the same or different as needed, thereby expanding the spray range of the water mist and improving the dust reduction effect. The lifting mechanism drives the annular upper cover to move up and down, and the annular upper cover drives the filter box, water inlet box, filter mechanism, rotary transmission mechanism and spray mechanism to move up and down synchronously, thereby adjusting the height of the spray mechanism, so that the spray mechanism can reduce dust at different positions, thereby improving the application range of the dust reduction device.

[0019] 2 When dust suppression is working, multiple L-shaped blocks are driven to rotate through the rotating transmission mechanism, and the L-shaped blocks drive the rotating ring to rotate, thereby causing multiple spray pipes to rotate, and the spray pipes drive the spray head to rotate, expanding the spraying range of the spray head, thereby improving the dust suppression effect.

[0020] 3. The filter mechanism is driven to rotate synchronously through the rotating transmission mechanism. The filter frame and filter net in the filter mechanism can shake up and down while rotating. The filter frame drives the cleaning mechanism to move up and down when it moves up and down, so that the cleaning end of the cleaning brush in the cleaning mechanism is always in contact with the filter net. At this time, the filter frame drives the filter net to rotate while the impurities filtered out from the side of the filter net are cleaned by the cleaning brush. At the same time, the filter net shakes up and down to further prevent the filtered impurities from clogging the mesh of the filter net, so that the filter net can continue to filter impurities in the water.

[0021] 4. During dust reduction work, adjust the filter in the circular groove at the upper end of the sphere to filter the water. At this time, the lower end of the sphere is in the cleaning tank, and the cleaning tank is filled with cleaning liquid, so that the filter in the circular groove at the lower end of the adjusting sphere is in the cleaning liquid in the cleaning tank; at this time, the filter shakes up and down, and then is swept by the cleaning mechanism to clean the impurities on the filter, so that the impurities fall from the filter into the cleaning liquid, completing the cleaning of the impurities on the filter and in the circular groove. It is only necessary to replace the cleaning liquid in the cleaning tank regularly.

[0022] 5. While adjusting the filter in the circular groove at the upper end of the sphere to filter the water, adjust the filter in the circular groove at the lower end of the sphere to self-clean. By turning the crank, the rotating shaft is driven to rotate 180 degrees, so that the adjusting sphere is rotated 180 degrees, and the positions of the two circular grooves on the adjusting sphere are interchanged. The circular groove drives the rotating frame and the filter therein to rotate synchronously, and this reciprocating cycle is repeated, so that the filter after each adjustment can continuously and efficiently filter impurities in the water. The operation is simple and convenient, which greatly improves work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] Both sides of the upper extrusion block 62 close to the support ring 63 and both sides of the lower extrusion block 64 close to the filter frame 6 are sloped.

[0050] The first regular polygon rod 52 is driven to rotate through the connecting head 54, and the first regular polygon rod 52 drives the first regular polygon rod 52 below it to rotate synchronously through the cylinder 5. When the first regular polygon rod 52 rotates, it drives the lifting sleeve 56 to rotate synchronously, and the lifting sleeve 56 drives the filter frame 6 to rotate synchronously. When the filter frame 6 rotates, it drives the filter screen 61 and the upper extrusion block 62 to rotate. When the upper extrusion block 62 rotates, it slides along the lower extrusion block 64. At this time, the slope of the upper extrusion block 62 is in sliding contact with the slope of the lower extrusion block 64 until the end of the upper extrusion block 62 is in contact with the end of the lower extrusion block 64.

At this time, the filter frame 6 drives the filter screen 61 to rotate, and the impurities filtered out from the side of the filter screen 61 are cleaned by the cleaning mechanism.

[0053] At this time, the filter screen 61 in the circular groove 41 at the upper end of the sphere 4 is adjusted to filter the water. The filter screen 61 is shaken up and down to prevent impurities from clogging the filter screen 61. At the same time, the impurities on the filter screen 61 are further cleaned by the cleaning mechanism, which can effectively prevent impurities from clogging the mesh of the filter screen 61. The impurities in the water are filtered out by the filter screen 61 to prevent the impurities from entering the spraying mechanism.

The filter screen 61 in the circular groove 41 at the lower end of the regulating sphere 4 is in the cleaning liquid in the cleaning tank 31. At this time, the filter screen 61 shakes up and down, and then is swept by the cleaning mechanism to clean the impurities on the filter screen 61, so that the impurities fall from the filter screen 61 into the cleaning liquid, completing the cleaning of the impurities on the filter screen 61 and in the circular groove 41. It is only necessary to regularly replace the cleaning liquid in the cleaning tank 31.

[0055] While adjusting the filter net 61 in the circular groove 41 at the upper end of the sphere 4 to filter the water, adjust the filter net 61 in the circular groove 41 at the lower end of the sphere 4 to self-clean, and repeat this process alternately, so that the filter net 61 after each adjustment can continuously and efficiently filter impurities in the water.

[0056] See also Figure 8 and Fig. 9 The locking mechanism includes an internal threaded sleeve 45 inserted into the side of the crank 44, the internal threaded sleeve 45 is connected to a locking screw 46, the end of the locking screw 46 is fixedly connected to a plug rod 47, and the plug rod 47 can move along the inner cavity of the internal threaded sleeve 45. The side of the filter box 3 is symmetrically provided with holes 32, and the two holes 32 are symmetrically distributed near the rotating shaft 43, and the plug rod 47 is plugged into the hole 32.

[0057] When the crank 44 needs to be rotated, the plug rod 47 is separated from the socket 32, and the crank 44 is rotated 180 degrees, and the crank 44 drives the adjusting ball 4 to rotate 180 degrees through the rotating shaft 43, so that the positions of the two circular grooves 41 of the adjusting ball 4 are interchanged, and this reciprocating process is repeated, so that the filter screens 61 in the two circular grooves 41 filter the water alternately;

[0058] After the adjustment is completed, the locking screw 46 is screwed in along the internal threaded sleeve 45, and the locking screw 46 drives the insertion rod 47 to be inserted into the insertion hole 32, thereby locking the crank 44, making the crank 44 unable to continue to rotate, and at the same time making the rotating shaft 43 and the adjusting ball 4 unable to rotate.

[0059] See also Figures 10 to 12 The cleaning mechanism includes a transverse plate 65 symmetrically fixedly connected to the end of the circular groove 41, and a cleaning brush 66 is arranged on the side of the transverse plate 65 close to the filter frame 6.

The two sides of the spring piece 69 are respectively in contact with the cleaning brush 66 and the transverse plate 65, and the spring piece 69 applies an elastic force to the cleaning brush 66.

[0060] When the filter frame 6 moves toward the end of the circular groove 41, the filter frame 6 pushes the resistance block 67 to move synchronously, and the resistance block 67 drives the cleaning brush 66 to move synchronously. When the filter frame 6 returns to its original position, the cleaning brush 66 and the resistance block 67 move back under the action of the elastic force of the spring piece 69, so that the cleaning part of the cleaning brush 66 is always in contact with the filter frame 6 and the filter net 61.

[0064] The output shaft drives the driving gear 7 to rotate, the driving gear 7 drives the transmission gear 71 to rotate, the transmission gear 71 drives the second regular polygon rod 8 to rotate through the transmission column 72, the second regular polygon rod 8 drives the clamping block 84 to rotate through the docking block 83, and the clamping block 84 drives the connecting head 54 to rotate.

[0065] When the adjusting ball 4 needs to be rotated, the handle 81 is first pulled upward, and the handle 81 drives the second regular polygon rod 8 to slide upward along the regular polygon groove 73. The second regular polygon rod 8 drives the clamping block 84 to move upward through the docking block 83, so that the clamping block 84 is separated from the clamping groove 55, and at the same time, the docking block 83 and the clamping block 84 are moved away from the adjusting ball 4, so that the clamping block 84 does not affect the normal rotation of the adjusting ball 4. When the docking block 83 moves upward, it squeezes the docking spring 82;

[0066] When the adjustment of the adjusting ball 4 is completed, the handle 81 is released, and the docking block 83 moves downward under the action of the elastic force of the docking spring 82, and the docking block 83 drives the clamping block 84 to move downward, so that the clamping block 84 is clamped with the clamping groove 55;

[0068] When the docking block 83 rotates, the docking block 83 drives the clamping block 84 to rotate. When the clamping block 84 rotates to the top of the clamping slot 55, the clamping block 84 is clamped with the clamping slot 55 under the action of the elastic force of the docking spring 82. At this time, the docking block 83 continues to rotate, and drives the connector 54 to rotate synchronously through the clamping block 84.

[0070] The locking mechanism includes a circular block 96 arranged on the side of the L-shaped block 91, and a fan-shaped support block 961 is symmetrically fixedly connected to one side of the circular block 96 close to the L-shaped block 91. Guide grooves 962 are provided on the inner sides of the two fan-shaped support blocks 961. A locking screw 97 is inserted through the side of the circular block 96. The locking screw 97 is threadedly connected to the circular block 96. The end of the locking screw 97 extends between the two fan-shaped support blocks 961. The end of the locking screw 97 is rotatably connected to a locking crown gear 971 through a pin shaft. The locking crown gear 971 is clamped with the rotating crown gear 941. The side of the locking crown gear 971 is symmetrically fixedly connected with a guide block 972, and the guide block 972 is slidably connected to the guide groove 962.

[0071] When the driving gear 7 rotates, the annular plate 701 is driven to rotate, the annular plate 701 drives the multiple L-shaped blocks 91 to rotate, the L-shaped blocks 91 drive the rotating ring 9 to rotate, thereby causing the multiple spray pipes 92 to rotate, and the spray pipes 92 drive the spray head 93 to rotate, thereby expanding the spraying range of the spray head 93.

[0072] The locking screw 97 is fixedly connected to the pin shaft, and the pin shaft is rotatably connected to the locking crown gear 971. By rotating the locking screw 97 along the circular block 96, the locking screw 97 is screwed in or out along the circular block 96, so that the locking screw 97 drives the locking crown gear 971 to move through the pin shaft, so that the locking crown gear 971 is engaged or separated from the rotating crown gear 941. When the rotating crown gear 941 moves, it drives the guide block 972 to slide along the guide groove 962, so that the locking crown gear 971 can only move along the guide block 972 and cannot rotate.

[0073] The rotating crown gear 941 can be locked by the locking mechanism so that the circular shaft 94 cannot rotate. The circular shaft 94 is fixed to the spray pipe 92. After the circular shaft 94 is locked, the spray pipe 92 also cannot rotate. The spray pipe 92 can be locked by the locking mechanism. Multiple spray pipes 92 can be adjusted to multiple inclination angles as needed, so that the spray head 93 of each spray pipe 92 sprays in a different direction, thereby expanding the spraying range of water and improving the dust reduction efficiency.

[0074] Working principle: the position of the spray pipe 92 can be adjusted as needed. The inclination angles of the multiple spray pipes 92 can be the same, or the inclination angles of the multiple spray pipes 92 can be different as needed, thereby expanding the spraying range of the water mist and improving the dust reduction effect.

[0075] When adjusting, first unscrew the locking screw 97 along the circular block 96 to separate the locking crown gear 971 from the rotating crown gear 941. At this time, the spray pipe 92 can be rotated upward or downward at will. When the spray pipe 92 rotates, it rotates around the axis of the circular shaft 94. After the position of the spray pipe 92 is adjusted, screw the locking screw 97 along the circular block 96 to engage the locking crown gear 971 with the rotating crown gear 941, thereby locking the spray pipe 92.

[0076] The lifting mechanism then drives the annular upper cover 38 to move up and down, and the annular upper cover 38 drives the filter box 3, the water inlet box 36, the filter mechanism, the rotary transmission mechanism and the spray mechanism to move up and down synchronously, thereby adjusting the height of the spray mechanism, so that the spray mechanism can reduce dust at different positions, thereby improving the application range of the dust reduction device.

[0077] During dust suppression operation, the water in the water storage tank 11 is pumped out through the water pump 12, so that the water flows into the water inlet box 36 along the connecting hose 371 and the water inlet pipe 37, and the water flows along the water inlet box 36 to the circular groove 41, and the water flows downward through the filter screen 61 in the circular groove 41, and the impurities in the water can be filtered through the filter screen 61, and the filtered water flows along the water outlet groove 42 and the connecting groove 35 to the upper end of the filter box 3, that is, it is collected in the annular cavity, and at this time, the filtered water flows along the water outlet hose 95 to the spray pipe 92, and finally the water is sprayed along the spray head 93 to form water mist, and the sprayed water mist is used to suppress dust in the air;

[0078] At this time, the rotating transmission mechanism drives multiple L-shaped blocks 91 to rotate, and the L-shaped blocks 91 drive the rotating ring 9 to rotate, so that multiple spray pipes 92 rotate, and the spray pipes 92 drive the spray head 93 to rotate, expanding the spraying range of the spray head 93, thereby improving the dust reduction effect.

[0079] At this time, the output shaft of the motor drives the driving gear 7 to rotate, the driving gear 7 drives the transmission gear 71 to rotate, the transmission gear 71 drives the second regular polygonal rod 8 to rotate through the transmission column 72, the second regular polygonal rod 8 drives the clamping block 84 to rotate through the docking block 83, the clamping block 84 drives the connecting head 54 to rotate, the connecting head 54 drives the first regular polygonal rod 52 to rotate, the first regular polygonal rod 52 drives the first regular polygonal rod 52 below it to rotate synchronously through the cylinder 5, so that the two first regular polygonal rods 52 both drive the lifting sleeves 56 thereon to rotate synchronously, and the lifting sleeve 56 drives the filter frame 6, the filter screen 61, and the upper extrusion block 62 to rotate;

[0080] The upper extrusion block 62 is made to rotate along the plurality of lower extrusion blocks 64 in a circular motion. With the cooperation of the upper extrusion block 62, the lower extrusion block 64 and the return spring 53, the upper extrusion block 62 is made to vibrate up and down, and the upper extrusion block 62 drives the filter frame 6 and the filter screen 61 to vibrate up and down.

[0081] When the filter frame 6 moves up and down, it drives the cleaning mechanism to move up and down, so that the cleaning end of the cleaning brush 66 in the cleaning mechanism is always in contact with the filter screen 61. At this time, the filter frame 6 drives the filter screen 61 to rotate, and the impurities filtered out from the side of the filter screen 61 are cleaned by the cleaning brush 66. At the same time, the filter screen 61 shakes up and down to further prevent the filtered impurities from clogging the mesh of the filter screen 61, so that the filter screen 61 can continue to filter impurities in the water.

[0082] At this time, the filter screen 61 in the circular groove 41 at the upper end of the sphere 4 is adjusted to filter the water to prevent impurities from entering the spray mechanism, and the filtered impurities are accumulated in the circular groove 41 and above the filter screen 61.

[0083] When it is necessary to clean the impurities in the filter screen 61 and the circular groove 41, the crank handle 44 is rotated one hundred and eighty degrees, and the crank handle 44 drives the adjusting ball 4 to rotate one hundred and eighty degrees through the rotating shaft 43, so that the positions of the two circular grooves 41 of the adjusting ball 4 are interchanged. At this time, the circular groove 41 and the filter screen 61 containing impurities are rotated to the lower end of the filter box 3, and are now above the inner cavity of the cleaning tank 31. At the same time, the cleaned filter screen 61 is rotated to the upper side, so that the positions of the two circular grooves 41 are interchanged. After the adjustment is completed, the insertion rod 47 in the locking mechanism is inserted into the socket 32, thereby locking the crank handle 44, and the adjusting ball 4 cannot rotate.

[0084] Continue the dust reduction work, adjust the filter screen 61 in the circular groove 41 at the upper end of the sphere 4 to filter the water, and at the same time adjust the rotating frame 6 and the filter screen 61 in the two circular grooves 41 at the upper and lower ends of the sphere 4 to shake up and down. At this time, the lower end of the sphere 4 is in the cleaning tank 31, and the cleaning tank 31 is filled with cleaning liquid, so that the filter screen 61 in the circular groove 41 at the lower end of the sphere 4 is in the cleaning liquid in the cleaning tank 31;

[0085] At this time, the filter screen 61 shakes up and down, and then is swept by the cleaning mechanism, thereby cleaning away the impurities on the filter screen 61, causing the impurities to fall from the filter screen 61 into the cleaning liquid, completing the cleaning of the impurities on the filter screen 61 and in the circular groove 41. It is only necessary to regularly replace the cleaning liquid in the cleaning tank 31.

[0086] While adjusting the filter net 61 in the circular groove 41 at the upper end of the sphere 4 to filter the water, adjust the filter net 61 in the circular groove 41 at the lower end of the sphere 4 to self-clean, and repeat this process alternately, so that the filter net 61 after each adjustment can continuously and efficiently filter impurities in the water. The operation is simple and convenient, which greatly improves work efficiency.
