Description

Technical Field

During construction, the construction area needs to be enclosed with a wall, and sprinkler nozzles are installed on the wall. The sprinkler nozzles spray water mist. When the dust in the construction site spreads to the edge of the wall, the dust absorbs the water mist, and the weight increases, causing the dust to settle, thus ensuring the environment around the construction site.

[0003] For example, the patent with the national authorized patent announcement number CN218901274U discloses a construction dust reduction fence, including a main body, a water collection mechanism and a dust reduction mechanism, wherein the water collection mechanism is located at the upper end of the main body, and the dust reduction mechanism is located at the upper end of the front end of the main body.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. Through the design of the wall water tank, connecting frame, back plate, water collecting tank, splicing mechanism, atomizing dust reduction mechanism and reciprocating push-pull mechanism, when in use, the staff can splice and discharge multiple sets of wall water tanks through the splicing mechanism according to the site area. This flexibility makes the dust reduction work adaptable to construction sites of different sizes. Whether it is a small construction site or a large construction project site, the dust reduction needs can be met by adjusting the splicing number and arrangement of the wall water tank, which improves the versatility of the equipment. Then, the ball valve can be connected to the external water pipe and water can be injected into the wall water tank for the atomizing dust reduction mechanism to draw the water source in the wall water tank and spray it out in atomization. The water mist can cover the construction site more evenly, effectively absorb dust particles, and reduce the dust content in the air. While spraying the water mist, the reciprocating push-pull mechanism can be started to push and pull the atomizing dust reduction mechanism up and down and left and right to swing, which greatly increases the spraying range of the water mist, further improves the dust reduction effect, and reduces the dust pollution to the construction site and the surrounding environment. In addition, through atomizing dust reduction and spraying in a larger range, the water resources in the wall water tank can be more fully utilized. Compared with spraying in a fixed direction and a limited range, this method can make every drop of water play a greater role in dust reduction, avoid the waste of water resources, and meet the requirements of energy saving and environmental protection.

[0022] In daily use, the water collecting trough opened on the upper surface of the back panel can collect and store rainwater in the wall water tank, and can atomize and spray it out when in use. In the process of starting the reciprocating push-pull mechanism, the reciprocating push-pull mechanism will also rotate together in the water collecting trough to scrape out debris, which can prevent debris from accumulating in the water collecting trough and entering the wall water tank or affecting the rainwater collection function of the water collecting trough. Keeping the water collecting trough clean can ensure the normal operation of the entire dust reduction system and reduce equipment failures caused by problems such as blockage by debris.

[0023] 2. Through the design of the first arc clamp, the second arc clamp, the lock buckle, the C-shaped column and the lock tongue, when multiple sets of wall water tanks are spliced ​​together, the top of the C-shaped column at one end of the connecting frame of another set of wall water tanks can be inserted into the first arc clamp, and then the second arc clamp can be turned over and sleeved on the outer surface of the C-shaped column, and the lock buckle at one end of the second arc clamp can be buckled on the outer surface of the lock tongue at one end of the first arc clamp, thereby realizing the locking sleeve of the first arc clamp and the second arc clamp on the outer surface of the C-shaped column, that is, realizing the splicing operation between multiple wall water tanks, and this simple splicing method can make multiple sets of wall water tanks The splicing process is completed quickly. In construction sites, time is often tight. Quick splicing can reduce the time of equipment installation, so that dust reduction work can be put into use faster and the dust reduction function can be brought into play as soon as possible, so that staff can splice and discharge multiple sets of wall water tanks according to the site area. This flexibility allows dust reduction work to adapt to construction sites of different sizes. Whether it is a small construction site or a large construction project site, the dust reduction needs can be met by adjusting the number and arrangement of splicing water tanks, thereby improving the versatility of the equipment.

[0024] 3. Through the design of the first connecting pipe, the second connecting pipe, the first bevel gear, the second bevel gear, the submersible pump and the L-shaped pipe, after splicing multiple sets of wall water tanks, the submersible pump can be started, and the submersible pump can draw water from the wall water tank and discharge it into the second connecting pipe through the straight pipe and the bearing seat, and the second connecting pipe is connected to the first connecting pipe through the L-shaped pipe, so that the submersible pump injects water into the first connecting pipe and the second connecting pipe, and the first connecting pipe and the second connecting pipe spray water mist through the atomizing nozzles connected and installed on the surface, so as to achieve dust reduction operation;

[0025] While spraying water mist, the reciprocating push-pull mechanism can also be started to push and pull the docking rod fixedly installed at one end of the outer surface of the first connecting tube, driving the first connecting tube to rotate in an up and down swing shape between the two sets of connecting frames, and the swinging rotation of the first connecting tube will drive the first bevel gear to mesh with the second bevel gear, so that the second bevel gear drives the second connecting tube to swing left and right horizontally in the connecting frame. This up and down and left and right swinging rotation can greatly increase the coverage of the water mist and achieve all-round dust reduction, which can effectively avoid the dust reduction dead corners caused by spraying in a single direction, so that the dust on the construction site can be more thoroughly suppressed, and through the swinging and rotating operation, the water mist can be more evenly distributed in the construction area, and each drop of water mist can better play a dust reduction role. Compared with spraying in a fixed direction, the waste of water resources caused by local excessive spraying is reduced, and the utilization efficiency of water resources is improved.

[0026] 4. Through the design of the double-shaft motor, eccentric shaft, connecting arm and U-shaped scraper, when the first connecting pipe and the second connecting pipe spray water mist, the double-shaft motor can be started to drive the connecting arm at one end of the eccentric shaft to rotate, and the other end of the connecting arm is rotatably installed on the outer surface of the docking rod, so that the connecting arm pushes and pulls the docking rod up and down to drive the first connecting pipe to rotate between the two sets of connecting frames, and then the first connecting pipe can be driven by the first bevel gear to mesh with the second bevel gear on the upper surface of the second connecting pipe, so as to drive the first connecting pipe and the second connecting pipe to swing and rotate in the up and down and left and right directions to increase the coverage of the water mist and achieve all-round dust reduction;

[0027] In addition, the dual-axis motor drives the eccentric shaft to rotate while also driving the C-shaped scraper to rotate and scrape inside the water collection tank. This automatic scraping function reduces the workload of manual cleaning of the water collection tank, making equipment maintenance more convenient. There is no need to arrange special personnel to perform frequent cleaning work, which can ensure the normal operation of the water collection tank and the entire dust reduction equipment.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] See also Figure 1-Figure 7 , this embodiment provides the following technical solutions:

[0038] like Figure 1-Figure 2 As shown, a construction dust reduction fence comprises: a fence water tank 1, connecting frames 101 are fixedly installed on both sides of the fence water tank 1, and atomizing dust reduction mechanisms 3 are rotatably installed between two sets of connecting frames 101 and in the connecting frames 101;

[0039] Among them, the two sets of connecting frames 101 are fixedly installed with a splicing mechanism 2 at one end, so that the wall water tank 1 can be buckled on the outer surface of the splicing mechanism 2 of another set of wall water tanks 1 through the splicing mechanism 2, so as to realize the splicing of multiple sets of wall water tanks 1;

[0040] Among them, one end of the wall water tank 1 is connected to a back plate 102, and an installation groove 107 is sealed between the back plates 102. A reciprocating push-pull mechanism 4 is fixedly installed in the installation groove 107. The push-pull end of the reciprocating push-pull mechanism 4 is rotatably connected to one end of the atomizing dust reduction mechanism 3, so that the reciprocating push-pull mechanism 4 can reciprocately push and pull the atomizing dust reduction mechanism 3 to swing up and down and left and right within the two sets of connecting frames 101 and the connecting frames 101.

[0041] Water collecting grooves 105 are provided on both sides of the upper surface of the back plate 102. Filter holes are provided in the water collecting grooves 105, so that the water collecting grooves 105 are connected with the back plate 102 and the wall water tank 1 through the filter holes, so that the water collecting grooves 105 can receive rainwater and store it in the back plate 102 and the wall water tank 1.

[0042] One end of the back plate 102 is connected to a tee pipe 104 , and the other end of the tee pipe 104 is connected to a ball valve 103 , so that the ball valve 103 can be connected to a water pipe to fill water into the wall water tank 1 .

[0043] Through the design of the wall water tank 1, the connecting frame 101, the back plate 102, the water collecting trough 105, the splicing mechanism 2, the atomizing dust reduction mechanism 3 and the reciprocating push-pull mechanism 4, when in use, the staff can splice and discharge multiple sets of wall water tanks 1 through the splicing mechanism 2 according to the area of ​​the site. This flexibility allows the dust reduction work to adapt to construction sites of different sizes. Whether it is a small construction site or a large construction project site, the dust reduction needs can be met by adjusting the splicing number and arrangement of the wall water tank 1, thereby improving the versatility of the equipment. Subsequently, the ball valve 103 can be connected to the external water pipe and water can be injected into the wall water tank 1, so that the atomizing dust reduction mechanism 3 can draw the water source in the wall water tank 1 into the wall water tank 1 and inject the water into the wall water tank 1. The atomized water mist can cover the construction site more evenly, effectively absorb dust particles, and reduce the dust content in the air. While spraying the water mist, the reciprocating push-pull mechanism 4 can be started to reciprocate and push-pull the atomizing dust reduction mechanism 3 to perform up and down and left and right swing operations, which greatly increases the spraying range of the water mist, further improves the dust reduction effect, and reduces the dust pollution to the construction site and the surrounding environment. In addition, through atomizing dust reduction and spraying in a larger range, the water resources in the wall water tank 1 can be more fully utilized. Compared with spraying in a fixed direction and a limited range, this method can make every drop of water play a greater role in dust reduction, avoid waste of water resources, and meet the requirements of energy saving and environmental protection.

[0044] In the process of daily use, the water collecting trough 105 opened on the upper surface of the back plate 102 can collect and store rainwater in the wall water tank 1, and can spray it out in atomization when in use. In the process of starting the reciprocating push-pull mechanism 4, the reciprocating push-pull mechanism 4 will also rotate in the water collecting trough 105 to scrape out debris, which can prevent debris from accumulating in the water collecting trough 105, avoid debris from entering the wall water tank 1 or affecting the rainwater collection function of the water collecting trough 105, keep the water collecting trough 105 clean, and ensure the normal operation of the entire dust reduction system, and reduce equipment failures caused by problems such as blockage by debris.

[0045] like Figure 3 As shown, the splicing mechanism 2 includes a first arc clamp 201, which is fixedly mounted on one end of the connecting frame 101, and a second arc clamp 202 is rotatably mounted on one end of the first arc clamp 201, so that the first arc clamp 201 and the second arc clamp 202 can fit a C-shaped column 204 therein, and the C-shaped column 204 is fixedly mounted on one end of the connecting frame 101 on the other side, thereby realizing the splicing of multiple sets of wall water tanks 1.

[0046] A lock buckle 203 is rotatably installed at one end of the second arc clamp 202, and the lock buckle 203 can be buckled on the outer surface of the lock tongue 205. The lock tongue 205 is fixedly installed at one end of the first arc clamp 201, so that the pulling force of the first arc clamp 201 on the outer surface of the lock tongue 205 through the lock buckle 203 can pull the second arc clamp 202 to one end of the first arc clamp 201, so that the first arc clamp 201 and the second arc clamp 202 can be firmly mounted on the outer surface of the U-shaped column 204.

[0047] Through the design of the first arc clip 201, the second arc clip 202, the lock buckle 203, the C-shaped column 204 and the lock tongue 205, when multiple sets of wall water tanks 1 are spliced ​​together, the C-shaped column 204 at one end of the connecting frame 101 of another set of wall water tanks 1 can be inserted into the first arc clip 201, and then the second arc clip 202 can be turned over and sleeved on the outer surface of the C-shaped column 204, and the lock buckle 203 at one end of the second arc clip 202 can be buckled on the outer surface of the lock tongue 205 at one end of the first arc clip 201, thereby realizing the locking sleeve of the first arc clip 201 and the second arc clip 202 on the outer surface of the C-shaped column 204, that is, the splicing of multiple wall water tanks 1 is realized. The simple splicing method can quickly complete the splicing process between multiple sets of wall water tanks 1. At construction sites, time is often tight, and fast splicing can reduce the time for equipment installation, so that the dust reduction work can be put into use faster and the dust reduction function can be brought into play as soon as possible, so that the staff can splice and discharge multiple sets of wall water tanks 1 according to the site area. This flexibility allows the dust reduction work to adapt to construction sites of different sizes. Whether it is a small construction site or a large construction project site, the dust reduction needs can be met by adjusting the splicing quantity and arrangement of the water tanks, thereby improving the versatility of the equipment.

[0048] like Figure 4-Figure 5 As shown, the atomization dust reduction mechanism 3 includes a first connecting pipe 301 and two groups of second connecting pipes 305. The first connecting pipe 301 and the two groups of second connecting pipes 305 are rotatably installed between the two groups of connecting frames 101 and in the two groups of connecting frames 101 respectively. An L-shaped pipe 303 is rotatably connected between the first connecting pipe 301 and the second connecting pipe 305. The L-shaped pipe 303 is located in the connecting frame 101. The lower surface of the second connecting pipe 305 is rotatably installed in the bearing seat 106. The bearing seat 106 is fixedly installed on the lower surface of the connecting frame 101. One end of the bearing seat 106 is connected and installed with a straight pipe 307. The straight pipe 307 is sealed and penetrates into the wall water tank 1. The other end of the straight pipe 307 is connected and installed with the drain outlet of the submersible pump 306. The submersible pump 306 is fixedly installed on the lower surface of the wall water tank 1.

[0049] First bevel gears 302 are fixedly installed on both sides of the first connecting pipe 301. The first bevel gears 302 rotate in the connecting frame 101 and mesh with the second bevel gears 304. The second bevel gears 304 are fixedly installed on the upper surface of the second connecting pipe 305. One end of the first connecting pipe 301 and the second connecting pipe 305 are connected and multiple groups of atomizing nozzles are installed.

[0050] Through the design of the first connecting pipe 301, the second connecting pipe 305, the first bevel gear 302, the second bevel gear 304, the submersible pump 306 and the L-shaped pipe 303, after a plurality of sets of wall water tanks 1 are spliced ​​together, the submersible pump 306 can be started, and the submersible pump 306 can draw water from the wall water tank 1 and discharge it into the second connecting pipe 305 through the straight pipe 307 and the bearing seat 106, and the second connecting pipe 305 is connected to the first connecting pipe 301 through the L-shaped pipe 303, so that the submersible pump 306 injects water into the first connecting pipe 301 and the second connecting pipe 305, so that the first connecting pipe 301 and the second connecting pipe 305 spray water mist through the atomizing nozzles connected and installed on the surface, thereby realizing the dust reduction operation;

[0051] When spraying water mist, the reciprocating push-pull mechanism 4 can be started to push and pull the docking rod 308 fixedly installed at one end of the outer surface of the first connecting tube 301, driving the first connecting tube 301 to rotate in an up and down swinging shape between the two sets of connecting frames 101, and the swinging rotation of the first connecting tube 301 will drive the first bevel gear 302 to mesh with the second bevel gear 304, so that the second bevel gear 304 drives the second connecting tube 305 to rotate horizontally in the connecting frame 101. This up and down and left and right swinging rotation can greatly increase the coverage of the water mist and achieve all-round dust reduction. It can effectively avoid the dust reduction dead corners caused by spraying in a single direction, so that the dust on the construction site can be more thoroughly suppressed. Moreover, through the swinging and rotating operation, the water mist can be more evenly distributed in the construction area, and each drop of water mist can better play a dust reduction role. Compared with spraying in a fixed direction, the waste of water resources caused by local excessive spraying is reduced, and the utilization efficiency of water resources is improved.

[0052] like Figure 6-Figure 7 As shown, the reciprocating push-pull mechanism 4 includes a dual-axis motor 401, which is fixedly installed in the installation groove 107. The outer surfaces of the output shafts on both sides of the dual-axis motor 401 are fixedly installed with eccentric shafts 402. A connecting arm 403 is rotatably installed in the eccentric shaft 402. The other end of the connecting arm 403 is rotatably installed on the outer surface of the docking rod 308. The docking rod 308 is fixedly installed on one end of the outer surface of the first connecting tube 301.

[0053] The connecting arm 403 can be driven by the eccentric shaft 402 of the dual-axis motor 401 to rotate in a reciprocating push-pull state of the docking rod 308, so that the docking rod 308 can pull the first connecting tube 301 to swing up and down between the two groups of connecting frames 101, and the up and down swinging first connecting tube 301 will drive the first bevel gear 302 to mesh and transmit the two groups of second bevel gears 304, so that the second bevel gear 304 can drive the second connecting tube 305 to swing left and right in the connecting frame 101.

[0054] A C-shaped scraper 404 is fixedly installed at one end of the eccentric shaft 402. The C-shaped scraper 404 passes through the installation groove 107 and is rotatably installed in the water collection tank 105, so that the C-shaped scraper 404 is driven by the dual-axis motor 401 to rotate counterclockwise, so that the C-shaped scraper 404 can scrape and push out the debris in the water collection tank 105.

[0055] Through the design of the double-axis motor 401, the eccentric shaft 402, the connecting arm 403 and the U-shaped scraper 404, when the first connecting tube 301 and the second connecting tube 305 spray water mist, the double-axis motor 401 can be started to drive the connecting arm 403 at one end of the eccentric shaft 402 to rotate, and the other end of the connecting arm 403 is rotatably installed on the outer surface of the docking rod 308, so that the connecting arm 403 pushes and pulls the docking rod 308 up and down to drive the first connecting tube 301 to rotate between the two groups of connecting frames 101, and then the first connecting tube 301 can be driven by the first bevel gear 302 to mesh with the second bevel gear 304 on the upper surface of the second connecting tube 305, so as to drive the first connecting tube 301 and the second connecting tube 305 to swing and rotate in the up-down and left-right directions to increase the coverage of the water mist and realize all-round dust reduction;

[0056] When the dual-axis motor 401 drives the eccentric shaft 402 to rotate, it will also drive the U-shaped scraper 404 to rotate and scrape inside the water collection tank 105. This automatic scraping function reduces the workload of manual cleaning of the water collection tank 105, making the maintenance of the equipment more convenient. There is no need to arrange special personnel to perform frequent cleaning work, which can ensure the normal operation of the water collection tank 105 and the entire dust reduction equipment.

[0057] According to the above technical scheme, the working steps of this scheme are summarized and sorted out: when in use, the staff can splice and arrange multiple sets of wall water tanks 1 according to the area of ​​the site, and when splicing, the top of the U-shaped column 204 at one end of the connecting frame 101 of another set of wall water tanks 1 can be inserted into the first arc clamp 201, and then the second arc clamp 202 can be turned over and sleeved on the outer surface of the U-shaped column 204, and the lock buckle 203 at one end of the second arc clamp 202 can be buckled on the outer surface of the lock tongue 205 at one end of the first arc clamp 201. The first arc clamp 201 and the second arc clamp 202 are locked on the outer surface of the U-shaped column 204, that is, the splicing operation between multiple wall water tanks 1 is realized. After the multiple sets of wall water tanks 1 are spliced, the submersible pump 306 can be started, and the submersible pump 306 can draw water from the wall water tank 1 and discharge it into the second connecting pipe 305 through the straight pipe 307 and the bearing seat 106, and the second connecting pipe 305 is connected to the first connecting pipe 301 through the L-shaped pipe 303. , so that the submersible pump 306 injects water into the first connecting pipe 301 and the second connecting pipe 305, so that the first connecting pipe 301 and the second connecting pipe 305 spray water mist through the atomizing nozzle installed on the surface, so as to realize dust reduction operation, and while spraying water mist, the dual-axis motor 401 can also be started to drive the connecting arm 403 at one end of the eccentric shaft 402 to rotate, and the other end of the connecting arm 403 is rotatably installed on the outer surface of the docking rod 308, so that the connecting arm 403 pushes and pulls the docking rod 308 up and down to drive the first connecting pipe 301 to perform an up and down swinging rotation operation between the two sets of connecting frames 101, and the swinging rotation of the first connecting pipe 301 will drive the first bevel gear 302 to mesh with the second bevel gear 304, so that the second bevel gear 304 drives the second connecting pipe 305 to swing left and right horizontally in the connecting frame 101, and this swinging rotation in the up and down and left and right directions can greatly increase the coverage of the water mist and realize all-round dust reduction.

[0058] In summary: through the up and down and left and right swinging water mist spraying operation, the dust reduction dead corners caused by single-direction spraying can be effectively avoided, and the dust on the construction site can be more thoroughly suppressed. Through the swinging and rotating operation, the water mist can be more evenly distributed in the construction area, and each drop of water mist can better play a dust reduction role. Compared with spraying in a fixed direction, it reduces the waste of water resources caused by local excessive spraying and improves the utilization efficiency of water resources.
