Description

Technical Field

[0001] This application relates to the field of construction site dust suppression technology, and in particular to a construction site dust suppression robot. Background Technology

[0002] Construction dust is a major source of particulate matter pollution in the atmosphere. This pollution is particularly severe during construction activities, accounting for 32% of urban dust. Dust has a significant impact on human health and the living environment, hence the use of spraying methods to suppress it.

[0003] During construction operations, the area requiring dust suppression varies in size. For example, in large-scale construction projects such as high-rise buildings, large commercial complexes, or infrastructure construction, the site area is vast, generating significant dust. Wide-area spraying is needed to effectively suppress dust, maintain clean air, and minimize the impact on workers and the surrounding environment. On the other hand, small-scale renovation or repair projects within cities, such as road repairs or pipeline maintenance, require precise, small-area spraying due to limited working space to avoid affecting the surrounding environment and pedestrians. However, existing dust suppression equipment has a fixed spray range and cannot be adjusted according to actual dust suppression needs. Utility Model Content

[0004] The purpose of this application is to address the aforementioned problems in the prior art by proposing a construction site dust suppression robot.

[0005] This application can be achieved through the following technical solution: a construction site dust suppression robot, including a frame, a walking module for moving the frame, a control module for controlling the walking module, a water tank on the frame, and a water outlet module for spraying. The water outlet module includes two sliding frames slidably connected to the frame, a movable spray head fixedly installed on the sliding frames, a water supply component for sending water from the water tank to the movable spray head, a rack on the sliding frames, a gear meshing with the racks on both sliding frames, and a gear driver for driving the gear to rotate. The rotation of the gear can drive the two sliding frames to slide, so that the movable spray heads on the two sliding frames move closer to each other or further away from each other.

[0006] In the above technical solution, the walking module can drive the frame to move as a whole, and the water supply component can supply water to the moving spray head. Since the sliding frame is slidably connected to the frame, the gear drive drives the gear to rotate, and the gear can drive the rack to slide so that the moving spray heads on the two sliding frames are closer to each other or further away from each other. The staff can adjust the position of the two sliding frames according to the site conditions to adapt to the dust suppression needs of different sites.

[0007] Furthermore, the frame includes a support bracket on which a water tank is mounted, a fixed frame on which a gear drive is fixedly mounted, and a fixed frame drive for driving the fixed frame to slide along the height direction of the support bracket. The fixed frame drive is mounted on the support bracket, and the sliding frame is slidably connected to the fixed frame.

[0008] In the above technical solution, the fixed frame driver can drive the mobile spray head to move up and down through the fixed frame, thereby changing the spray height of the mobile spray head and making it more widely applicable.

[0009] Furthermore, a fixed spray head is installed on the fixed frame, and the water supply assembly can supply water to the fixed spray head.

[0010] In the above technical solution, the fixed spray head can also be used for dust suppression. When the area to be sprayed is small, there is no need to adjust the relative position of the two sliding frames; the fixed spray head can be used directly for dust suppression.

[0011] Furthermore, a groove is provided on the frame, the groove is fitted with the water tank, and a screw cap is installed on the water tank. The screw cap is detachably connected to the water tank so that the inside and outside of the water tank can communicate.

[0012] In the above technical solution, the water tank is embedded in the groove, and the position of the water tank can be fixed. The staff can unscrew the cap to fill the water tank with water.

[0013] Furthermore, the bottom of the water tank is provided with a water inlet, and the inside of the water tank is provided with a sealing element that can block the water inlet. The water supply component includes a top block and a water delivery component for delivering water leaving the water tank to the movable spray head. When the water tank is embedded in the groove, the top block can lift the sealing element so that the water leaves the water tank through the water inlet.

[0014] In the above technical solution, when the water tank is not placed in the groove, the sealing element can block the water inlet. After the water tank is placed in the groove, the top block can lift the sealing element, and the water can leave the water tank through the water inlet.

[0015] Furthermore, the water delivery assembly includes a water funnel and a water pump. The water funnel is mounted on the frame and is used to collect water leaving the water tank. The water pump can deliver the water in the water funnel into the movable spray head.

[0016] In the above technical solution, water leaving the water tank through the water inlet can be pumped by the water pump into the movable spray head through the water funnel.

[0017] Furthermore, a water tank cover is hinged to the frame, and the water tank cover can abut against the surface of the water tank away from the bottom of the groove.

[0018] In the above technical solution, the water tank cover can apply force to the bottom of the groove through the water tank, so that the water tank is not easy to fall out of the groove when the frame encounters bumpy road sections.

[0019] Furthermore, the walking module includes a tire mounted on a frame and a tire drive for driving the tire to rotate; the tire is a honeycomb tire.

[0020] Among the above technical solutions, honeycomb tires have advantages such as durability, strong anti-roll performance, strong off-road performance, and strong shock resistance, making them more suitable for use on construction sites.

[0021] Furthermore, a bumper is installed on the frame.

[0022] In the above technical solution, by setting up a bumper, when the robot is involved in a collision, the bumper can absorb and mitigate the external impact force, thereby protecting the frame and the various devices on the frame.

[0023] Furthermore, the rack is equipped with a camera and a searchlight.

[0024] In the above technical solution, by setting up a camera, it is easy for staff to control the overall movement of the robot, and by setting up a searchlight, it is easy for the dust removal robot to work at night.

[0025] In summary, this application has the following technical effects: the walking module can drive the frame to move as a whole, the water supply component can supply water to the moving spray head, and since the sliding frame is slidably connected to the frame, the gear drive can drive the rack to slide during the rotation of the gear, so that the moving spray heads on the two sliding frames can move closer to each other or further away from each other. The staff can adjust the position of the two sliding frames according to the site conditions to adapt to the dust suppression needs of different sites. Attached Figure Description

[0033] Reference Figure 1 One embodiment of this application provides a construction site dust suppression robot, including a frame 1. The frame 1 includes a support frame 11, on which a groove 111 is formed. A water tank 4 is embedded in the groove 111. A screw cap 41 is threaded onto the water tank 4, allowing workers to unscrew the screw cap 41 to fill the water tank 4 with water. A fixed frame driver 13 is mounted on the support frame 11. The fixed frame driver 13 is an electric actuator. A fixed frame 12 is detachably mounted on the telescopic end of the fixed frame driver 13. The fixed frame driver 13 is used to drive the fixed frame 12 to slide along the height direction of the support frame 11.

[0034] Reference Figure 1 and Figure 2 The frame 1 is equipped with a water outlet module 5 for spraying. The water outlet module 5 includes two sliding frames 51 slidably connected to the fixed frame 12. A gear driver 56 is mounted on the fixed frame 12. The gear driver 56 is a motor, and a gear 55 is mounted on the output end of the gear driver 56. The gear driver 56 drives the gear 55 to rotate. Each sliding frame 51 is equipped with a rack 54, and the racks 54 on both sliding frames 51 mesh with the gears 55. Each sliding frame 51 is equipped with a movable spray head 52. The rotation of the gears 55 can drive the two sliding frames 51 to slide horizontally in a straight line, thereby changing the distance between the two movable spray heads 52.

[0035] Reference Figure 1Each of the two sliding blocks has a groove 511 along its length. The two grooves 511 are slidably connected to the fixed frame 12. The rotation of the gear 55 allows the sliding frame 51 to slide along the length of the groove 511. Multiple protective covers 14 are also installed on the sliding frame 51. The multiple protective covers 14 are evenly distributed at the upper and lower ends of the sliding frame 51. The protective covers 14 are connected to both sliding frames 51 by screws. This design can reduce the risk of damage to the rack 54 from impact when the robot is being transported as a whole.

[0036] Reference Figure 1 , Figure 3 and Figure 4 A fixed spray head 6 is installed on the fixed frame 12. The fixed spray head 6 and two movable spray heads 52 are all supplied with water through a water supply assembly 53. The bottom of the water tank 4 has several water inlets 42 arranged around the same circumference. A sealing element 7 is placed inside the water tank 4. The sealing element 7 includes a sealing block 71 with an opening and a sealing strip 72 installed at the opening of the sealing block 71. The sealing strip 72 can be made of rubber. The sealing strip 72 can fit against the inner bottom surface of the water tank 4, and the sealing element 7 can cover the several water inlets 42 to prevent water from leaving the water tank 4 from the water inlets 42. A through-hole is provided at the bottom of the water tank 4 at the center of the circumference of several water inlets 42. The water supply assembly 53 includes a top block 531. A water funnel 5321 is installed on the support frame 11. The water funnel 5321 is located below the water tank 4. The top block 531 includes a mounting bracket 5311 installed on the water funnel 5321. The mounting bracket 5311 has multiple water inlets 53111. Four vertically arranged springs 5312 are installed on the mounting bracket 5311. 5312 is a compression spring. A push-out block 5313 is installed at the top of the spring 5312. The outlet is used for the push-out block 5313 to extend into the water tank 4. The spring 5312 can force the push-out block 5313 to abut against the bottom of the water tank 4. When the water tank 4 is embedded in the groove 111, the top of the push-out block 5313 can lift the sealing block 71 so that the sealing block 71 slides away from the bottom surface of the water tank 4. The water in the water tank 4 can then enter the water funnel 5321 through the water inlet 42 and the water outlet 53111.

[0037] Reference Figure 5The water supply assembly 53 also includes a water delivery assembly 532 for delivering water entering the water funnel 5321 to the mobile spray head 52 and the fixed spray head 6. The water delivery assembly 532 includes a water funnel 5321 and a water pump 5322 connected to the bottom of the water funnel 5321. The water funnel 5321 is mounted on the support frame 11 and located at the bottom of the water tank 4. The outlet of the water pump 5322 is connected to two solenoid valves 15 through a pipe. The water pump 5322 is a diaphragm pump. The outlet of one solenoid valve 15 is connected to the fixed spray head 6 through a hose. The outlet of the other solenoid valve 15 is equipped with a main pipe. The main pipe is connected to two branch pipes through a pipe joint. The two branch pipes are respectively connected to the two mobile spray heads 52 through a hose.

[0038] Reference Figure 1 A walking module 2 is mounted on the support frame 11. The walking module 2 is used to move the entire frame 1. The walking module 2 includes six tires 21 mounted on the support frame 11 and tire actuators 22 for driving the rotation of the tires 21. The tire actuators 22 are motors. The tires 21 are honeycomb tires, which have advantages such as durability, strong anti-rolling performance, strong off-road performance, and strong shock resistance. When the robot needs to turn as a whole, the tires 21 on both sides of the frame 1 can be rotated in opposite directions.

[0039] Reference Figure 1 Two water tank covers 8 are hinged on the support frame 11. Both water tank covers 8 are "L" shaped and are set opposite to each other. The water tank covers 8 can abut against the surface of the water tank 4 away from the bottom of the groove 111. The water tank covers 8 can exert force on the bottom of the groove 111 through the water tank 4 so that the water tank 4 is not easy to fall out of the groove 111 when encountering bumpy road sections.

[0040] Reference Figure 1 A bumper 9 is installed at the end of the support frame 11 away from the fixed frame driver 13. By installing the bumper 9, when the robot collides, the bumper 9 can absorb and mitigate external impact forces, thereby protecting the frame 1 and the various devices on it. A camera 16 is installed at the end of the support frame 11 near the bumper 9. A searchlight 17 is installed on both sides of the camera 16. The camera 16 facilitates the operator's control of the robot's overall movement, and the searchlights 17 facilitate the dust-reducing robot's operation at night.

[0041] Reference Figure 5The support frame 11 has an internal power supply, and a control box 31 is mounted on the support frame 11. The walking module 2, solenoid valve 15, water pump 5322, fixed frame driver 13, gear driver 56, etc., can all be controlled by the control module 3. The control module 3 includes a remote control and a control box 31 mounted on the support frame 11. The control box 31 contains a signal receiver. The signal can be Bluetooth, infrared, WiFi, etc. The signal receiver converts the received signal into an electrical signal and decodes it to identify the operator's specific command, such as forward, backward, left turn, or right turn. The decoded signal is transmitted to the control unit, which can use a microcontroller. The control unit converts the received command into a corresponding control signal. For example, the control unit can send the processed signal to the tire driver 22. The tire driver 22 drives the tire 21 to rotate according to the received control signal, realizing the forward, backward, or turning movement of the vehicle. Workers can control the robot's overall forward, backward, and turning movements, as well as the opening and closing of the solenoid valve 15 and water pump 5322, and the operation of the gear drive 56 or the fixed frame drive 13 by pressing a button on the remote control to send a signal to the signal receiver.

[0042] The working principle of this embodiment is as follows: The walking module 2 can drive the frame 1 to move as a whole, thereby spraying different areas of the construction site. When it is necessary to adjust the distance between the two moving spray pipes, the control module 3 can control the gear driver 56 to drive the gear 55 to rotate, so that the two moving spray heads 52 can move closer or further away from each other, so that the position of the moving spray head 52 can be adapted to the actual spraying needs of the construction site.

[0043] 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.
