Description

Technical Field

[0001] This invention relates to the field of building engineering technology, and in particular to building engineering environmental monitoring devices. Background Technology

[0002] During the construction process, it is necessary to monitor the environment of the construction site to ensure the safety of construction workers. However, during the construction process, a lot of dust often floats in the air at the construction site. Dust can easily adhere to the lens surface of the monitoring device and obstruct the view of the monitoring device.

[0003] Existing construction engineering environmental monitoring devices can only monitor the construction environment and cannot reduce dust. Dust in the air can not only block the camera lens of the monitoring device, but also endanger the health of workers. Summary of the Invention

[0004] This application provides an environmental monitoring device for construction projects, which can reduce dust in the construction environment, reduce the possibility of dust obscuring the monitoring device lens, and enable the monitoring device to work better.

[0005] The building engineering environmental monitoring device provided in this application adopts the following technical solution:

[0006] A building construction environmental monitoring device includes a housing; the top of the housing has an opening, and a pad is fixedly connected to the inner wall of the housing; a support plate is provided on the top of the pad; the support plate is slidably engaged with the inner wall of the housing, and a support frame is fixedly connected to the top of the support plate; a monitoring camera body is fixedly connected to the top of the support frame; a water pipe is rotatably connected to the top of the support plate; the end of the water pipe away from the support plate passes through the support frame and extends to the outside of the support frame, and a disc is fixedly connected to the end of the water pipe extending out of the support frame; the disc has a cavity inside, and a disc is fixedly connected to the outer wall of the disc. It has an atomizing nozzle; the cavity is connected to the inside of the water pipe; the atomizing nozzle is connected to the inside of the cavity; a water tank and a water pump are fixedly connected to the inner side wall of the bottom end of the housing; an inlet pipe is fixedly connected to the input end of the water pump, and an outlet pipe is fixedly connected to the output end of the water pump; the end of the inlet pipe away from the water pump is connected to the water tank; the end of the outlet pipe away from the water pump extends through the support plate into the inside of the water pipe, and the outlet pipe is connected to the inside of the water pipe; the housing is equipped with a power mechanism that pushes the support plate to slide up and down; the support frame is equipped with a jet spray mechanism to expand the spray coverage area.

[0007] By adopting the above technical solution, when it is necessary to monitor the building environment, the power mechanism pushes the support plate to slide up, causing the support plate to drive the support frame and the monitoring camera body to slide up and extend outside the shell. The monitoring camera body monitors the external environment. To reduce the interference of building dust on the monitoring camera body, the water pump is started to transport clean water from the water tank to the water outlet pipe through the water inlet pipe. The water outlet pipe then transports the clean water to the water pipe and the interior of the disc cavity. Finally, the clean water is sprayed to the outside by the atomizing nozzle, thereby spraying the external environment to reduce dust. Then, the jetting mechanism sprays the water vapor sprayed from the atomizing nozzle to make the water vapor spread to a greater distance, improving the dust reduction effect.

[0008] Preferably, the jetting mechanism includes a first motor, a placement box, and an air vent; the first motor is mounted on the outer wall of the support frame, and a first rotating shaft is fixedly connected to the output end of the first motor; a cam is fixedly connected to the outer wall of the first rotating shaft; the placement box is fixedly connected to the top of the support plate, and a pressure plate is slidably connected to the inner wall of the placement box; the top of the pressure plate has an arc surface that cooperates with the cam, and a pair of first springs are fixedly connected to the bottom of the pressure plate; the ends of the pair of first springs away from the pressure plate are fixedly connected to the inner wall of the bottom end of the placement box; an airbag is provided inside the placement box; the airbag is in contact with the bottom of the pressure plate; the air vent is fixedly connected to the top of the support frame, and the air vent communicates with the inside of the airbag; multiple jet nozzles are fixedly connected to the outer wall of the air vent; the multiple jet nozzles communicate with the inside of the air vent.

[0009] By adopting the above technical solution, the first motor is started to drive the first rotating shaft and cam to rotate. During the rotation of the cam, it contacts the rounded corner at the top of the pressure plate. Through the cooperation between the cam and the rounded corner, the pressure plate slides down along the placement box and squeezes the air bag. The gas inside the air bag enters the ventilation pipe and is sprayed out by the jet nozzle. The gas sprayed out by the jet nozzle blows the water vapor, allowing the water vapor to spread to a farther position and improving the dust reduction effect on the external environment. When the cam loses contact with the rounded corner, the pressure plate slides up and resets under the elastic force of the first spring, so that the cam can squeeze the pressure plate again, and the jet nozzle can perform reciprocating blowing work on the water vapor.

[0010] Preferably, a first bevel gear is fixedly connected to the end of the first rotating shaft away from the first motor; a second bevel gear is fixedly connected to the outer wall of the water pipe near the first bevel gear; the second bevel gear meshes with the first bevel gear.

[0011] By adopting the above technical solution, when the first motor drives the first rotating shaft to rotate, the first rotating shaft drives the first bevel gear to rotate, and the first bevel gear drives the second bevel gear and the water pipe to rotate, thereby driving the disc and the atomizing nozzle to rotate, making the water vapor spray more uniform.

[0012] Preferably, the power mechanism includes a second motor; the second motor is mounted on the inner side wall of the bottom end of the housing, and a lead screw is fixedly connected to the output end of the second motor; the lead screw passes through the support plate, and the lead screw and the inner side wall of the support plate are connected by a ball screw thread pair; a pair of first sliding grooves are provided on the outer side wall of the housing; a limiting member is provided inside the pair of first sliding grooves to prevent the support plate from sliding down.

[0013] By adopting the above technical solution, when the support plate slides upward, the second motor is started to drive the lead screw to rotate. The lead screw is connected to the inner wall of the support plate by a ball screw nut pair, so that the support plate slides upward along the inner wall of the housing. When the support plate slides to the designated position, the support plate is fixed by the limiting component, so that the support plate remains stable.

[0014] Preferably, the limiting member includes a pull plate and an insert plate; the insert plate is slidably connected inside the first slide groove, and the side wall of the insert plate near the support plate is provided with an inclined surface; the top of the support plate near the side wall of the insert plate is provided with a rounded corner that cooperates with the inclined surface; the pull plate is fixedly connected to the side wall of the insert plate extending out of the housing, and a pair of second springs are fixedly connected to the side wall of the pull plate near the housing; the ends of the pair of second springs away from the pull plate are fixedly connected to the outer side wall of the housing; the support plate is provided with a slot on the side wall of the surface where the insert plate is located that cooperates with the insert plate.

[0015] By adopting the above technical solution, when the support plate slides down, the side wall of the support plate gradually approaches and contacts the insert plate. Through the cooperation of the rounded corners and the inclined surface, the support plate pushes the insert plate to slide along the first slide groove and stretches the second spring. As the support plate continues to rise, the end of the insert plate with the inclined surface is inserted into the slot on the side wall of the support plate, thereby fixing the support plate and keeping it stable. When the support plate needs to return to the initial position, the pull plate is pulled to pull the insert plate out of the slot, and then the first motor drives the support plate to slide down to the initial position.

[0016] Preferably, the housing sidewall is provided with a clearance groove; a cover plate is slidably connected to the inner sidewall of the opening; a handle is fixedly connected to the top of the cover plate, and a rack plate is fixedly connected to the bottom of the cover plate; a cleaning mechanism for cleaning the lens of the monitoring camera body is provided on the inner sidewall of the housing; the cleaning mechanism is driven by the rack plate.

[0017] By adopting the above technical solution, when monitoring is not required, both the support frame and the monitoring camera body are located inside the housing. The cover plate seals the opening to protect the monitoring camera body and reduce the possibility of accidental damage. When monitoring is required, pulling the handle causes the cover plate to slide, opening the opening and allowing the monitoring camera body to extend out of the housing for monitoring. During the sliding process of the cover plate, the rack plate also slides, and the groove design facilitates the rack plate to extend out of the housing. The rack plate drives the cleaning mechanism to clean the lens of the monitoring camera body, reducing the possibility of dust adhering to the lens and enabling the monitoring camera body to perform better monitoring work.

[0018] Preferably, the cleaning mechanism includes a second rotating shaft, a third rotating shaft, and a cleaning brush; the second rotating shaft is rotatably connected to the inner wall of the housing, a spur gear is fixedly connected to the side wall of the second rotating shaft near the rack plate, and a third bevel gear is fixedly connected to the end of the second rotating shaft away from the inner wall of the housing; the spur gear meshes with the rack plate; the third rotating shaft is fixedly connected to the inner wall of the housing, and a fourth bevel gear is fixedly connected to the outer wall of the third rotating shaft near the third bevel gear; the fourth bevel gear meshes with the third bevel gear; the cleaning brush is fixedly connected to the end of the third rotating shaft near the monitoring camera body, and the cleaning brush contacts the monitoring camera body.

[0019] By adopting the above technical solution, when the push handle 19 is pulled to slide the cover plate, the rack plate drives the spur gear to rotate, which in turn drives the second shaft and the third bevel gear to rotate. Under the meshing of the third and fourth bevel gears, the third shaft rotates, thereby driving the cleaning brush to rotate and clean the dust and impurities adhering to the lens of the surveillance camera body, ensuring the cleanliness of the lens of the surveillance camera body.

[0020] Preferably, a pair of second sliding grooves are provided on the side wall of the opening; a pair of limiting blocks are fixedly connected to the side wall of the cover plate; the pair of limiting blocks slide in cooperation with the inner side wall of the pair of second sliding grooves.

[0021] By adopting the above technical solution, when the cover plate slides, the limiting block slides along the second sliding groove. The cooperation between the limiting block and the second sliding groove limits the cover plate, making it difficult for the cover plate to slide off the top of the housing.

[0022] Preferably, a receiving box is fixedly connected to the inner sidewall of the housing; the receiving box is located at the bottom of the cleaning brush.

[0023] By adopting the above technical solution, a receiving box is set up to collect dust and impurities that fall from the lens of the monitoring camera, which facilitates centralized treatment of dust and impurities and reduces the difficulty for staff to handle scattered dust.

[0024] Preferably, a water supply pipe is fixedly connected to the top of the water tank; the end of the water supply pipe away from the water tank extends through the shell and out of the shell; a roller is installed at the bottom of the shell, and a push handle is fixedly connected to the outer side wall of the shell.

[0025] By adopting the above technical solution, the staff pushes the handle to drive the roller to roll, which facilitates the overall movement of the device and improves the overall flexibility of the device. The water supply pipe is used to replenish clean water into the water tank.

[0026] In summary, this application has the following beneficial effects:

[0027] 1. By starting the water pump, clean water inside the water tank is transported from the inlet pipe to the outlet pipe, and then sprayed to the outside through the atomizing nozzle to achieve dust suppression in the external environment. When performing dust suppression, the first motor is started to drive the first rotating shaft and cam to rotate. During the rotation of the cam, it contacts the rounded corner on the top of the pressure plate. Through the cooperation of the cam and the rounded corner, the pressure plate slides down the placement box and squeezes the air bag. The gas inside the air bag enters the ventilation pipe and is sprayed out through the air nozzle. The gas sprayed out by the air nozzle blows the water vapor sprayed by the atomizing nozzle, so that the water vapor is diffused to a farther position, improving the dust suppression effect on the external environment.

[0028] 2. When monitoring is required, the second motor is started to drive the lead screw to rotate, causing the support plate to slide down. During the sliding process, the support plate gradually approaches the insertion plate. Through the cooperation of the rounded corners and the inclined surface, the support plate pushes the insertion plate to slide along the first sliding groove. As the support plate continues to rise, the insertion plate slides back under the action of the second spring, causing the end of the insertion plate to slide into the slot, thus supporting and limiting the support plate. This allows the monitoring camera body to extend out of the housing for monitoring. When monitoring is not required, the pull plate is pulled to slide the insertion plate out of the slot. The insertion plate loses its supporting and limiting effect on the support plate. The first motor is then started to drive the support plate down to the top of the pad, so that the monitoring camera body is inside the housing, and the housing protects the monitoring camera body.

[0029] 3. When the surveillance camera body comes into contact with the cleaning brush, the cover plate is pushed to drive the rack plate to slide, so that the rack plate drives the spur gear and the third bevel gear to rotate. Under the meshing of the third bevel gear and the fourth bevel gear, the third rotating shaft and the cleaning brush rotate. The cleaning brush cleans the dust and impurities adhering to the lens of the surveillance camera body, ensuring the cleanliness of the lens of the surveillance camera body. The dust and impurities cleaned by the cleaning brush 63 fall into the receiving box and are collected, which facilitates the centralized treatment of dust by the staff. Attached Figure Description

[0037] The present invention will be further described in detail below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," "lower," "bottom," and "top" used in the following description refer to directions in the drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0038] This invention discloses an environmental monitoring device for building engineering, such as... Figure 1 and Figure 2As shown, the device includes a housing 1; the top of the housing 1 has an opening 11, a pad 12 is fixedly connected to the inner wall of the housing 1, a roller 18 is installed at the bottom of the housing 1, a push handle 19 is fixedly connected to the outer wall of the housing 1, and a support plate 2 is provided on the top of the pad 12; the support plate 2 slides with the inner wall of the housing 1, and a support frame 3 is fixedly connected to the top of the support plate 2; a monitoring camera body 31 is fixedly connected to the top of the support frame 3; a power mechanism 4 for pushing the support plate 2 upward is provided inside the housing 1; the power mechanism 4 includes a second motor 41; the second motor 41 is installed on the inner wall of the bottom end of the housing 1, and a lead screw 42 is fixedly connected to the output end of the second motor 41; the lead screw 42 passes through the support plate 2, and the lead screw 42 is connected to the inner wall of the support plate 2 by a ball screw thread pair; the outer wall of the housing 1 has a... A pair of first sliding grooves 15; the pair of first sliding grooves 15 are provided with limiting members 16 to prevent the support plate 2 from sliding upward; the limiting members 16 include a pull plate 161 and an insert plate 162; the insert plate 162 is slidably connected inside the first sliding groove 15, and the side wall of the insert plate 162 near the support plate 2 is provided with an inclined surface 163; the top of the support plate 2 is provided with a rounded corner 23 that cooperates with the inclined surface 163 on the side wall near the insert plate 162; the pull plate 161 is fixedly connected to the side wall of the insert plate 162 extending out of the housing 1, and a pair of second springs 164 are fixedly connected to the side wall of the pull plate 161 near the housing 1; the ends of the pair of second springs 164 away from the pull plate 161 are fixedly connected to the outer side wall of the housing 1; the support plate 2 is provided with a slot 24 that cooperates with the insert plate 162 on the side wall of the side where the insert plate 162 is located.

[0039] Pushing the handle 19 causes the roller 18 to roll, moving the device to the designated position. Then, the second motor 41 is started to drive the lead screw 42 to rotate. During the rotation of the lead screw 42, the support plate 2 slides up along the inner wall of the housing 1. As the support plate 2 slides up, the side wall of the support plate 2 gradually approaches and contacts the insertion plate 162. Through the cooperation of the rounded corner 23 and the inclined surface 163, the support plate 2 pushes the insertion plate 162 to slide along the first slide groove 15 and stretches the second spring 164. As the support plate 2 continues to rise, the end of the insertion plate 162 where the inclined surface 163 is located is inserted into the slot 24 on the side wall of the support plate 2, thereby fixing the support plate 2 and keeping it stable. At this time, the support frame 3 and the monitoring camera body 31 extend to the outside of the housing 1, and the monitoring camera body 31 monitors the external environment.

[0040] like Figure 2 and Figure 3As shown, a water pipe 21 is rotatably connected to the top of the support plate 2; the end of the water pipe 21 away from the support plate 2 passes through the support frame 3 and extends to the outside of the support frame 3, and a disc 22 is fixedly connected to the end of the water pipe 21 extending out of the support frame 3; a cavity 221 is provided inside the disc 22, and an atomizing nozzle 222 is fixedly connected to the outer wall of the disc 22; the cavity 221 communicates with the inside of the water pipe 21; the atomizing nozzle 222 communicates with the inside of the cavity 221; a water tank 13 and a water pump 14 are fixedly connected to the inner wall of the bottom end of the housing 1; the top of the water tank 13... A water supply pipe 131 is fixedly connected to the water tank 13; the end of the water supply pipe 131 away from the water tank 13 passes through the housing 1 and extends to the outside of the housing 1; the input end of the water pump 14 is fixedly connected to the water inlet pipe 141, and the output end of the water pump 14 is fixedly connected to the water outlet pipe 142; the end of the water inlet pipe 141 away from the water pump 14 is connected to the water tank 13; the end of the water outlet pipe 142 away from the water pump 14 passes through the support plate 2 and extends into the water pipe 21, and the water outlet pipe 142 is sealed and fixedly connected to the inner wall of the support plate 2, and the water outlet pipe 142 is connected to the inside of the water pipe 21.

[0041] The water pump 14 is activated to transport clean water from the water tank 13 to the water outlet pipe 142 via the inlet pipe 141. The water outlet pipe 142 then transports the clean water to the water pipe 21 and the cavity 221 of the disc 22. Finally, the clean water is sprayed to the outside via the atomizing nozzle 222. The water vapor sprayed by the atomizing nozzle 222 reduces dust in the external environment, thereby reducing the possibility of dust in the external environment interfering with the monitoring camera body 31 and enabling the monitoring camera body 31 to perform monitoring work better. The water replenishment pipe 131 is used to replenish clean water into the water tank 13.

[0042] like Figure 2 and Figure 4 As shown, a jetting mechanism 5 for expanding the spray coverage area is provided on the support frame 3. The jetting mechanism 5 includes a first motor 51, a placement box 52, and an air pipe 53. The first motor 51 is mounted on the outer wall of the support frame 3, and a first rotating shaft 511 is fixedly connected to the output end of the first motor 51. A cam 512 is fixedly connected to the outer wall of the first rotating shaft 511. The placement box 52 is fixedly connected to the top of the support plate 2, and a pressure plate 54 is slidably connected to the inner wall of the placement box 52. The top of the pressure plate 54 is provided with an arc surface 541 that cooperates with the cam 512, and a pair of first springs 542 are fixedly connected to the bottom of the pressure plate 54. The ends of the pair of first springs 542 away from the pressure plate 54 are connected to the placement box 53. The inner side wall of the bottom end of the placement box 52 is fixedly connected; an airbag 55 is provided inside the placement box 52; the airbag 55 is in contact with the bottom of the pressure plate 54; the air pipe 53 is fixedly connected to the top of the support frame 3, and the air pipe 53 is connected to the inside of the airbag 55. Multiple air nozzles 531 are fixedly connected to the outer side wall of the air pipe 53; the multiple air nozzles 531 are connected to the inside of the air pipe 53, and the air nozzles 531 are inclined; a first bevel gear 513 is fixedly connected to the end of the first rotating shaft 511 away from the first motor 51; a second bevel gear 211 is fixedly connected to the outer side wall of the water pipe 21 near the first bevel gear 513; the second bevel gear 211 meshes with the first bevel gear 513.

[0043] When the first motor 51 drives the first rotating shaft 511 to rotate, the first rotating shaft 511 drives the first bevel gear 513 to rotate, and the first bevel gear 513 drives the second bevel gear 211 and the water pipe 21 to rotate, thereby causing the disc 22 and the atomizing nozzle 222 to rotate, thus making the water vapor spray more even. During the rotation of the first rotating shaft 511, the cam 512 is driven to rotate. Through the cooperation of the cam 512 and the rounded corner 23, the pressure plate 54 slides down along the placement box 52 and squeezes the air bag 55. The gas inside the air bag 55 enters the ventilation pipe 53 and is sprayed out by the air nozzle 531. The gas sprayed out by the air nozzle 531 blows the water vapor, making the water vapor diffuse to a farther position and improving the dust reduction effect on the external environment. When the cam 512 loses contact with the rounded corner 23, the pressure plate 54 slides up and resets under the elastic force of the first spring 542, so that the cam 512 can squeeze the pressure plate 54 again, so that the air nozzle 531 can perform reciprocating blowing work on the water vapor.

[0044] like Figure 2 and Figure 5 As shown, a clearance groove 17 is provided on the side wall of the housing 1; a cover plate 111 is slidably connected to the inner side wall of the opening 11; a handle 112 is fixedly connected to the top of the cover plate 111, and a rack plate 113 is fixedly connected to the bottom of the cover plate 111; a cleaning mechanism 6 for cleaning the lens of the monitoring camera body 31 is provided on the inner side wall of the housing 1; the cleaning mechanism 6 includes a second rotating shaft 61, a third rotating shaft 62, and a cleaning brush 63; the second rotating shaft 61 is rotatably connected to the inner side wall of the housing 1, and a spur gear 611 is fixedly connected to the side wall of the second rotating shaft 61 near the rack plate 113; the second rotating shaft 61 is away from the housing 1. A third bevel gear 612 is fixedly connected to the end of the inner sidewall of body 1; a spur gear 611 meshes with a rack plate 113; a third rotating shaft 62 is fixedly connected to the inner sidewall of housing 1, and a fourth bevel gear 621 is fixedly connected to the outer sidewall of the third rotating shaft 62 near the third bevel gear 612; the fourth bevel gear 621 meshes with the third bevel gear 612; a cleaning brush 63 is fixedly connected to the end of the third rotating shaft 62 near the monitoring camera body 31, and the cleaning brush 63 contacts the monitoring camera body 31; a receiving box 64 is fixedly connected to the inner sidewall of housing 1; the receiving box 64 is located at the bottom of the cleaning brush 63.

[0045] Initially, the surveillance camera body 31 is located inside the housing 1. Before moving the surveillance camera body 31 to the outside of the housing 1, pull the handle 112 to slide the cover plate 111, opening the opening 11. During the sliding process of the cover plate 111, the rack plate 113 slides, allowing the slot 17 to facilitate the rack plate 113 to extend outside the housing 1. The rack plate 113 drives the spur gear 611 to rotate, which in turn drives the second shaft 61 and the third bevel gear 612 to rotate. Under the meshing of the third bevel gear 612 and the fourth bevel gear 621, the third shaft 62 rotates, thereby driving the cleaning brush 63 to rotate and clean the dust and impurities adhering to the lens of the surveillance camera body 31, reducing the possibility of dust adhering to the lens and enabling the surveillance camera body 31 to perform better monitoring work. A receiving box 64 is provided to collect the dust and impurities that fall from the lens of the surveillance camera body 31, facilitating centralized treatment of dust and impurities and reducing the difficulty for staff to handle scattered dust.

[0046] like Figure 5 and Figure 6 As shown, a pair of second sliding grooves 114 are provided on the side wall of the opening 11; a pair of limiting blocks 115 are fixedly connected to the side wall of the cover plate 111; the pair of limiting blocks 115 slide in cooperation with the inner side wall of the pair of second sliding grooves 114; when the cover plate 111 slides, the limiting blocks 115 slide along the second sliding grooves 114, and the cover plate 111 is limited by the cooperation between the limiting blocks 115 and the second sliding grooves 114, so that the cover plate 111 is not easy to slide off the top of the housing 1.

[0047] Working principle: Pushing the push handle 19 moves the device to the designated position. In the initial state, the cover plate 111 covers the opening 11, and the monitoring camera body 31 is located inside the housing 1 and in contact with the cleaning brush 63. Pulling the push handle 19 causes the cover plate 111 to slide. When the cover plate 111 slides, the rack plate 113 drives the spur gear 611 and the third bevel gear 612 to rotate. Under the meshing of the third bevel gear 612 and the fourth bevel gear 621, the third rotating shaft 62 and the cleaning brush 63 rotate. The cleaning brush 63 cleans the dust and impurities adhering to the lens of the monitoring camera body 31, ensuring the cleanliness of the lens of the monitoring camera body 31. The dust and impurities cleaned by the cleaning brush 63 fall into the receiving box 64 and are collected, making it convenient for staff to clean the dust. Dust is centrally processed. During the sliding of the cover plate 111, the limiting block 115 slides along the second slide groove 114. The cooperation between the limiting block 115 and the second slide groove 114 limits the cover plate 111, making it difficult for the cover plate 111 to slide off the top of the housing 1. The second motor 41 is started to drive the lead screw 42 to rotate. During the rotation of the lead screw 42, the support plate 2, support frame 3 and monitoring camera body 31 slide upward. During the upward sliding of the support plate 2, the top of the support plate 2 gradually approaches and contacts the insertion plate 162. Through the cooperation between the rounded corner 23 and the inclined surface 163, the support plate 2 pushes the insertion plate 162 to slide along the first slide groove 15 and stretches the second spring 164. As the support plate 2 continues to rise, the insertion plate 162 in the second slide groove 164... Under the elastic force of spring 164, the end of insert plate 162 slides into slot 24 on the side wall of support plate 2, thereby supporting and limiting support plate 2. This allows the monitoring camera body 31 to extend outside the housing 1, facilitating monitoring of the external environment. To reduce the interference of external dust on the monitoring camera body 31, water pump 14 is activated to transport clean water from water tank 13 through inlet pipe 141 to outlet pipe 142. The outlet pipe 142 then transports the clean water to water pipe 21 and the cavity 221 of disc 22. Finally, the clean water is sprayed to the outside by atomizing nozzle 222, achieving dust suppression by spraying. During dust suppression, the first motor 51 is activated to drive the first rotation... Shaft 511 and cam 512 rotate. During the rotation of cam 512, it contacts the rounded corner 23 on the top of pressure plate 54. Through the cooperation of cam 512 and rounded corner 23, pressure plate 54 slides down along placement box 52 and squeezes air bag 55. The gas inside air bag 55 enters ventilation pipe 53 and is sprayed out by jet nozzle 531. The gas sprayed out by jet nozzle 531 blows the water vapor sprayed by atomizing nozzle 222, so that the water vapor spreads to a farther position and improves the dust reduction effect on the external environment. When cam 512 loses contact with rounded corner 23, pressure plate 54 slides up and resets under the elastic force of first spring 542, so that cam 512 can squeeze pressure plate 54 again, so that jet nozzle 531 can reciprocate to spray the sprayed water vapor.The water supply pipe 131 is used to replenish clean water into the water tank 13 to ensure the normal operation of the dust suppression spraying. During the rotation of the first shaft 511 driven by the first motor 511, the first shaft 511 drives the first bevel gear 513 to rotate, which in turn drives the second bevel gear 211 and the water pipe 21 to rotate, thereby rotating the disc 22 and the atomizing nozzle 222, resulting in more even water vapor spraying. When monitoring is not required, pulling the pull plate 161 causes the insert plate 162 to slide out of the slot 24, and the insert plate 162 loses its supporting and limiting function on the support plate 2. Then, the first motor 51 is restarted to drive the support plate 2 down to the pad 12. At the top, the support plate 2 is supported by the pad 12. At this time, the support frame 3 and the monitoring camera body 31 are inside the housing 1. The lens of the monitoring camera body 31 is in contact with the cleaning brush 63. Then, the cover plate 111 is pushed to slide and close the opening 11, thus protecting the monitoring camera body 31 and preventing accidental damage. During the sliding process of the cover plate 111, the rack plate 113 drives the spur gear 611 to rotate again, which causes the cleaning brush 63 in contact with the monitoring camera body 31 to clean the lens of the monitoring camera body 31 again, thereby ensuring the cleanliness of the lens of the monitoring camera body 31.

[0048] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
