Description

Technical Field

[0001] This invention belongs to the field of construction site monitoring equipment maintenance technology, specifically relating to a cleaning device for a globe-shaped monitoring probe at a construction site. Background Technology

[0002] In modern large-scale construction projects, safety monitoring, progress management, quality control, and remote collaboration all heavily rely on video surveillance systems deployed throughout the site. Among these, spherical surveillance cameras, with their 360° horizontal and large-angle vertical rotation and zoom capabilities, provide a wide, flexible, and directional monitoring field of view, making them a core component of construction site monitoring networks. However, the highly dynamic, complex, and heavily polluted environment of construction sites poses a significant challenge to the reliable operation of spherical cameras.

[0003] Earthwork operations, demolition, material cutting, and vehicle traffic generate large amounts of dust, sand, and cement powder, which are the main sources of probe contamination. Rainfall, dust suppression watering, and concrete work can easily generate mud splashes or water mist, which adhere to the probe surface. Contaminants (especially dust, mud spots, and water stains) adhere to the outer surface of the spherical protective cover (usually made of transparent acrylic or glass), which severely scatters and absorbs light, resulting in blurred monitoring images, reduced contrast, color distortion, and even completely obscuring the view of critical areas. Probes are usually installed on high poles, making manual cleaning inconvenient. Summary of the Invention

[0004] This invention addresses the problem of frequent cleaning of monitoring probes in construction sites, which is inconvenient due to manual wiping.

[0005] This invention provides the following technical solution: a cleaning device for a spherical monitoring probe at a construction site, comprising a column, a spherical monitoring probe, a lifting mechanism, and a cleaning mechanism;

[0006] The spherical monitoring probe is installed off the ground on the column, and the cleaning mechanism is mounted on the working end of the lifting mechanism. The lifting mechanism is attached to the column and is used to vertically transport the cleaning mechanism.

[0007] The cleaning mechanism includes cleaning bowls that are aligned vertically with the spherical monitoring probes. Each cleaning bowl includes a first plate with bristles, a second plate with a spray nozzle, and a third plate with a squeegee. The cleaning bowls rotate relative to each other over the spherical monitoring probes, and the first, second, and third plates respectively perform sweeping, spraying, and squeegeeing operations on the spherical monitoring probes.

[0008] Furthermore, the cleaning mechanism also includes a wastewater collection bowl, a ring frame, and lower support legs. The wastewater collection bowl is located below the cleaning bowl assembly and is used to collect dirt generated by brushing the spherical monitoring probe. The lower support legs support the ring frame, and the opening of the wastewater collection bowl is detachably connected to the ring frame. The first, second, and third lobes are each connected to the ring frame via upper support legs.

[0009] Furthermore, the nozzle on the second flap is connected to a cleaning fluid extrusion assembly, which includes a vertically installed storage tank. A push rod is connected to the piston inside the storage tank. The suction port at the bottom of the storage tank is connected to the first port of a three-way pipe. The second port of the three-way pipe is connected to the cleaning fluid tank through a suction pipe, and the third port is connected to the nozzle through an injection pipe. A first check valve is installed at the second port of the three-way pipe, and a second check valve is installed at the third port. A reaction frame is provided on the column to apply a counter-thrust to the push rod, thereby squeezing the liquid in the storage tank by the piston.

[0010] Furthermore, the spherical monitoring probe is installed on the swivel base of the column. The spherical monitoring probe is connected to the torque output mechanism, which includes a driving pulley, a driven pulley, a belt, and a servo motor. The driving pulley is installed on the output shaft of the servo motor, and the driven pulley is installed on the spherical monitoring probe. A belt connects the driving pulley and the driven pulley. The start-stop control component of the servo motor is linked with the lifting mechanism. When the lifting mechanism raises the cleaning mechanism to the set height, the start-stop control component connects the circuit of the servo motor.

[0011] Furthermore, the start / stop control assembly includes a control switch, a trigger block, a boom, a spring-loaded telescopic rod, and a lever. The boom is fixed to the column, the trigger block is slidably sleeved on the boom through a horizontal through slot, the spring-loaded telescopic rod supports the trigger block and the boom within the horizontal through slot, the lever is fixedly connected to the trigger block, and the sliding cap at the end of the lever is hinged to the lever plate of the control switch. A collision block is provided on the working end of the lifting mechanism. Both the collision block and the trigger block have chamfered edges on their collision sides. When the collision block rises, it pushes the trigger block away, thereby pushing the control switch open. After the collision block descends, the spring-loaded telescopic rod pushes the trigger block back to its original position, and the control switch closes.

[0012] Furthermore, the lifting mechanism includes a lead screw, a lead screw nut, and a support bracket; the lead screw is rotatably installed in the shaft hole at the center of the column, and a set of slide rails are opened on the column before and after the lead screw, the slide rails are connected to the shaft hole, the lead screw nut is screwed into the shaft hole and engaged with the lead screw, and a slider corresponding to each slide rail is fixed on the lead screw nut, the slider and the slide rail are slidably engaged, the support bracket is connected to the slider, the rotation of the lead screw drives the lead screw nut to move the support bracket up and down, and the cleaning mechanism is mounted on the support bracket.

[0013] Furthermore, the lead screw receives torque from a hand-cranked turntable at the base of the column. A driven bevel gear is mounted at the bottom of the lead screw, and a driving bevel gear is mounted on the shaft of the hand-cranked turntable. The driven bevel gear and the driving bevel gear mesh.

[0014] Furthermore, the support frame includes a support beam and a support platform. The slider has a vertical slot. The support beam is hung on the slider by a pin engaging with the slot. The support platform rests on the support beams in front of and behind the column. The cleaning mechanism is located on the top surface of the support platform.

[0015] Furthermore, the first and third lobes are elastic. When the cleaning bowl assembly is not in contact with the spherical monitoring probe, the lower ends of the first and third lobes converge towards the middle. When the cleaning bowl assembly is in contact with the spherical monitoring probe, the spherical monitoring probe pushes the first and third lobes apart, and the second lobe always maintains a pre-reserved distance from the spherical monitoring probe.

[0016] Furthermore, slots are provided on the opposite sides of the two load-bearing beams. The slots include an inlet section, a limiting section, and an installation section. The cleaning fluid tank is provided with two wing plates that engage with the slots on the load-bearing beams on both sides. The wing plates are pushed in from the inlet section of the slot, pass through the limiting section, and fall into the installation section. The step between the limiting section and the installation section prevents the wing plates from coming out.

[0017] Compared with the prior art, the advantages of the present invention are:

[0018] Through the coordinated operation of the lifting and cleaning mechanisms, the cleaning trays can be precisely delivered to each spherical monitoring probe position without the need for manual climbing and wiping. With the cooperation of the rotation of the spherical monitoring probes (driven by the torque output mechanism), the cleaning trays (first, second, and third segments) sequentially complete the sweeping, spraying, and wiping operations. The entire process is automated, greatly reducing the frequency and intensity of manual operation and avoiding the safety risks of workers performing cleaning operations at heights or in complex construction environments.

[0019] The cleaning bowl completely covers the probe and rotates relative to it as the probe rotates, ensuring that the bristles, cleaning solution, and squeegee can contact and clean all areas of the sphere's surface, leaving no blind spots. The flexible first and third lobes automatically adapt to the sphere's size, ensuring that the bristles and squeegee fit tightly against the sphere's surface, improving cleaning effectiveness. Spray washing (second lobe) and squeegee washing (third lobe) work continuously to effectively remove stubborn stains and quickly remove residual water stains, keeping the lens clear.

[0020] The specially designed wastewater collection bowl is located directly below the cleaning bowl assembly, effectively collecting wastewater and dirt generated during scrubbing and spraying, preventing dirty water from dripping and contaminating the equipment or floor below. The wastewater collection bowl is detachably connected to the ring frame, facilitating regular cleaning of the collected wastewater and dirt.

[0021] Through innovative mechanical structures and linkage control, the device has successfully achieved automatic, efficient, and non-blind-spot cleaning of spherical monitoring probes at the construction site, effectively solving the problems of inconvenient manual cleaning, low efficiency, and high risk. At the same time, it has the advantages of energy conservation, sewage collection, and convenient maintenance, significantly improving the maintenance efficiency and operation reliability of monitoring equipment.

[0039] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0040] like Figure 1 , Figure 2 , Figure 10 As shown: A cleaning device for a spherical monitoring probe at a construction site includes a column 1, a spherical monitoring probe 2, a lifting mechanism 3, and a cleaning mechanism 4;

[0041] The spherical monitoring probe 2 is installed off the ground on the column 1, and the cleaning mechanism 4 is mounted on the working end of the lifting mechanism 3. The lifting mechanism 3 is attached to the column 1 and is used to vertically transport the cleaning mechanism 4.

[0042] The cleaning mechanism 4 includes cleaning bowls that are aligned vertically with the spherical monitoring probe 2. Each cleaning bowl includes a first petal 4.1 with bristles, a second petal 4.2 with a spray nozzle, and a third petal 4.3 with a squeegee. The cleaning bowls rotate relative to each other over the spherical monitoring probe 2. The first petal 4.1, the second petal 4.2, and the third petal 4.3 respectively perform sweeping, spraying, and squeegeeing operations on the spherical monitoring probe 2.

[0043] The cleaning mechanism 4 is lifted to the position of the spherical monitoring probe 2 by the lifting mechanism 3. The cleaning bowl of the cleaning mechanism 4 covers the spherical monitoring probe 2. When the spherical monitoring probe 2 and the cleaning bowl rotate relative to each other, the bristles on the first petal 4.1 brush the surface of the spherical monitoring probe 2, the nozzle on the second petal 4.2 sprays cleaning liquid to spray the surface of the spherical monitoring probe 2, and the squeegee on the third petal 4.3 scrapes off the water droplets remaining on the surface of the spherical monitoring probe 2. The whole process is automated, which greatly reduces the frequency and intensity of manual operation.

[0044] Specifically, a top plate 16 is installed at the top of the column 1, and a rotary seat 5 is provided on the top plate 16. The spherical monitoring probe 2 is connected to the rotary seat 5, and the spherical monitoring probe 2 is connected to the torque output mechanism. The torque output mechanism drives the spherical monitoring probe 2 to rotate.

[0045] The first and third lobes 4.1 and 4.3 are elastic. When the cleaning bowl assembly is not in contact with the spherical monitoring probe 2, the lower ends of the first and third lobes 4.1 and 4.3 converge towards the middle. When the cleaning bowl assembly is in contact with the spherical monitoring probe 2, the spherical monitoring probe 2 opens the first and third lobes 4.1 and 4.3. The elastic design of the first and third lobes 4.1 and 4.3 can automatically adapt to the size of the sphere, ensuring that the bristles and squeegee fit tightly against the spherical surface and improve the cleaning effect. The second lobe 4.2 always maintains a distance from the spherical monitoring probe 2 so that the cleaning liquid sprayed from the nozzle can spread.

[0046] like Figure 7 , Figure 8 , Figure 9 As shown: The cleaning mechanism 4 also includes a wastewater collection bowl 4.4, a ring frame 4.5, and a lower support leg 4.6. The wastewater collection bowl 4.4 is located below the cleaning bowl assembly and is used to collect dirt generated during the scrubbing of the spherical monitoring probe 2. The lower support leg 4.6 supports the ring frame 4.5. The opening of the wastewater collection bowl 4.4 is detachably connected to the ring frame 4.5. The first petal 4.1, the second petal 4.2, and the third petal 4.3 are each connected to the ring frame 4.5 via an upper support leg 4.7. The wastewater collection bowl 4.4 can effectively collect wastewater and dirt generated during the scrubbing and spraying process, preventing dirty water from dripping and contaminating the equipment below or the ground. The wastewater collection bowl 4.4 is connected to the ring frame 4.5 by a threaded connection, which facilitates the regular cleaning of the collected wastewater and dirt.

[0047] The nozzle on the second flap 4.2 is connected to a cleaning fluid extrusion assembly, which includes a vertically installed reservoir 4.8. A push rod 4.9 is connected to a piston inside the reservoir 4.8. The suction port at the bottom of the reservoir 4.8 is connected to the first port of a three-way pipe 4.10. The second port of the three-way pipe 4.10 is connected to the cleaning fluid tank 4.12 via a suction pipe 4.11, and the third port is connected to the nozzle via an injection pipe 4.13. A check valve is installed at the second port of the three-way pipe 4.10. 4.14 A second check valve 4.15 is installed at the third pipe opening; a reaction frame is installed on the column 1 to apply a counter-force to the injection rod 4.9, thereby squeezing the liquid in the storage cylinder 4.8 by the piston. The top plate 16 serves as the reaction frame. When the lifting mechanism 3 raises the cleaning fluid extrusion assembly as a whole, the injection rod 4.9 touches the top plate 16 first. The cleaning fluid extrusion assembly continues to rise, and the injection rod 4.9 pushes the piston to squeeze the cleaning fluid in the storage cylinder 4.8. The cleaning fluid flows through the injection pipe 4.13 and is sprayed out from the nozzle.

[0048] The three-way pipe 4.10, in conjunction with check valve 4.14 and check valve 4.15, ensures that the cleaning fluid can only flow from the reservoir 4.8 to the nozzle, and can only be replenished from the cleaning fluid tank 4.12 to the reservoir 4.8, achieving a one-way and reliable fluid supply cycle. When the cleaning mechanism 4 is located at the lower end of the column 1, the push rod 4.9 is manually lifted, and the negative pressure draws the cleaning fluid in the cleaning fluid tank 4.12 into the reservoir 4.8. When the cleaning fluid flows through the three-way pipe 4.10, due to the negative pressure in the reservoir 4.8, the cleaning fluid will not flow to the injection pipe 4.13. Furthermore, due to the one-way sealing effect of check valve 4.15, there will be no pressure relief at the third port of the three-way pipe 4.10. During the cleaning fluid extrusion process, due to the one-way sealing effect of check valve 4.14, the cleaning fluid cannot flow out from the second port of the three-way pipe 4.10.

[0049] The cleaning fluid extrusion assembly is ingeniously designed. When the lifting mechanism 3 reaches the top, the push rod 4.9 contacts the top plate 16, generating a counterforce that drives the piston, thus achieving pressurized extrusion of the cleaning fluid. This process requires no additional power source (such as an electric pump), utilizing the device's own kinetic energy, resulting in a simple and energy-efficient structure.

[0050] like Figure 8 , Figure 11As shown: The torque output mechanism of the spherical monitoring probe 2 includes a drive pulley 6, a driven pulley 7, a belt 8, and a servo motor 9. The drive pulley 6 is mounted on the output shaft of the servo motor 9, and the driven pulley 7 is mounted on the spherical monitoring probe 2. The belt 8 connects the drive pulley 6 and the driven pulley 7. After the servo motor 9 starts, it drives the spherical monitoring probe 2 to rotate as a whole through the drive pulley 6, the driven pulley 7, and the belt 8. After the servo motor 9 starts, it is set to rotate one revolution forward and one revolution backward in a cycle to prevent the wiring of the spherical monitoring probe 2 from getting tangled. The start-stop control component of the servo motor 9 is linked with the lifting mechanism 3. When the lifting mechanism 3 lifts the cleaning mechanism 4 to the set height, the start-stop control component connects the circuit of the servo motor 9.

[0051] like Figure 12 , Figure 13 As shown: The start / stop control assembly includes a control switch 10, a trigger block 11, a boom 12, a spring-loaded telescopic rod 13, and a lever 14. The boom 12 is fixed to the column 1. The trigger block 11 is slidably sleeved on the boom 12 through a horizontal through groove 11.1. The trigger block 11 is fixed vertically but can slide freely horizontally. The spring-loaded telescopic rod 13 supports the trigger block 11 and the boom 12 within the horizontal through groove 11.1. The lever 14 is fixedly connected to the trigger block 11. The sliding cap 14.1 at the end of the lever 14 is hinged to the lever 10.1 of the control switch 10. The sliding cap 14.1 is slidably sleeved on the end of the lever 14. The head is used to compensate for the distance difference between the paddle 10.1 and the lever 14 when the paddle 10.1 moves; a collision block 15 is provided on the working end of the lifting mechanism 3. Both the collision block 15 and the trigger block 11 have chamfers on their collision sides. When the collision block 15 rises, it pushes the trigger block 11 away. The trigger block 11 pushes the paddle 10.1 through the lever 14 and the sliding cap 14.1, thereby pushing the control switch 10 to open. After the collision block 15 falls, the elastic telescopic rod 13 pushes the trigger block 11 to reset. The trigger block 11 pushes the paddle 10.1 in the opposite direction through the lever 14 and the sliding cap 14.1, and the control switch 10 is closed.

[0052] The start / stop control assembly links the lifting of the cleaning mechanism 4 with the rotation of the probe: when the cleaning mechanism 4 is raised to the set height (cleaning position), the collision block 15 triggers the control switch 10, and the servo motor 9 starts to drive the probe to rotate; when the cleaning ends and the probe descends, the servo motor 9 is automatically turned off. This design ensures that the cleaning action (rotation) is initiated only when needed, avoiding ineffective operation, saving energy and reducing wear. The chamfered design of the collision block 15 and the trigger block 11 makes the trigger / reset process smooth and reliable.

[0053] like Figure 3 , Figure 4As shown: The lifting mechanism 3 includes a lead screw 3.1, a lead screw nut 3.2, and a support bracket. The lead screw 3.1 is rotatably installed in the shaft hole 1.1 at the center of the column 1. A set of slide rails 1.2 are provided on the column 1 before and after the lead screw 3.1, communicating with the shaft hole 1.1. The lead screw nut 3.2 is screwed into the shaft hole 1.1 and engages with the lead screw 3.1. A slider 3.3, corresponding to each slide rail 1.2, is fixed to the lead screw nut 3.2, and the slider 3.3 slides and engages with the slide rail 1.2. The support bracket is connected to the slider 3.3. Rotation of the lead screw 3.1 drives the lead screw nut 3.2 to move the support bracket up and down. The cleaning mechanism 4 is mounted on the support bracket. The lifting mechanism 3 uses the lead screw nut 3.2 for transmission, and in conjunction with the slide rails 1.2 and sliders 3.3 within the column 1, it provides precise guidance, strong load-bearing capacity, and stable operation, capable of withstanding vibrations and loads from the construction environment. The overall structure relies on the existing column 1 of the monitoring probe, ensuring stable installation and saving space.

[0054] like Figure 5 As shown: The lead screw 3.1 receives torque from the hand-cranked turntable 3.6 at the base of column 1. A driven bevel gear 3.7 is installed at the bottom of the lead screw 3.1, and a driving bevel gear 3.8 is installed on the shaft of the hand-cranked turntable 3.6. The driven bevel gear 3.7 and the driving bevel gear 3.8 mesh. When the hand-cranked turntable 3.6 rotates, it drives the lead screw 3.1 to rotate through the driving bevel gear 3.8 and the driven bevel gear 3.7.

[0055] like Figure 6 , Figure 7 , Figure 8 As shown: The support bracket includes a support beam 3.4 and a support platform 3.5. A vertical slot 3.3.1 is opened on the slider 3.3. The support beam 3.4 is hung on the slider 3.3 through a pin 3.4.1 that engages with the slot 3.3.1. The support platform 3.5 rests on the support beams 3.4 in front of and behind the column 1. The bottom surface of the support platform 3.5 is provided with a stop bar to prevent the support beams 3.4 from moving. The two stop bars sandwich the two support beams 3.4 in the middle, preventing the support platform 3.5 from moving back and forth. A baffle is provided at the end of the support beam 3.4. The baffle engages with the column surface of the column 1 to prevent the support platform 3.5 from moving back and forth. The cleaning mechanism 4 is set on the top surface of the support platform 3.5. The support bracket and the slider 3.3 are connected by a pin, which facilitates installation, disassembly and maintenance.

[0056] Slots 3.4.2 are formed on the opposite surfaces of the two supporting beams 3.4. Each slot 3.4.2 includes an inlet section 3.4.2.1, a limiting section 3.4.2.2, and an installation section 3.4.2.3. The cleaning fluid tank 4.12 is equipped with two wing plates 4.12.1 that engage with the slots 3.4.2 on the two supporting beams 3.4. The wing plates 4.12.1 are pushed into the slots 3.4.2.1, pass through the limiting section 3.4.2.2, and then fall into the installation section 3.4.2.3. A step between the limiting section 3.4.2.2 and the installation section 3.4.2.3 prevents the wing plates 4.12.1 from dislodging. The cleaning fluid tank 4.12, through the engagement of the wing plates 4.12.1 with the slots 3.4.2 on the supporting beams 3.4.4, achieves quick installation and locking, making cleaning fluid replacement convenient and fast.
