Description

Technical Field

[0001] The invention belongs to the technical field of construction site monitoring equipment maintenance, and in particular relates to a cleaning device for a spherical monitoring probe at a construction site. Background Art

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

[0003] Earthwork, demolition, material cutting, and vehicle traffic generate large amounts of dust, sand, and cement powder, which are major sources of probe contamination. Rainfall, dust suppression with sprinklers, and concrete operations can easily create mud splashes or mist that adhere to the probe surface. Contaminants (especially dust, mud, and water stains) adhere to the outer surface of the dome (usually made of transparent acrylic or glass) and severely scatter and absorb light, resulting in blurred surveillance images, reduced contrast, color distortion, and even complete obstruction of view in critical areas. Probes are typically mounted on high poles, making manual cleaning inconvenient. Summary of the Invention

[0004] The present invention aims to solve the problem that monitoring probes in construction sites need to be frequently cleaned and manual wiping is inconvenient.

[0005] The present invention provides the following technical solutions: a spherical monitoring probe cleaning device for a construction site, comprising a column, a spherical monitoring probe, a lifting mechanism, and a cleaning mechanism; 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. The cleaning mechanism includes a cleaning bowl group aligned one by one with the spherical monitoring probe. Each cleaning bowl group includes a first lobe with bristles, a second lobe with a nozzle and a third lobe with a wiper. The cleaning bowl group cover rotates relative to the spherical monitoring probe. The first lobe, the second lobe and the third lobe respectively clean, spray and wipe the spherical monitoring probe.

[0006] Furthermore, the cleaning mechanism also includes a sewage collection bowl, a ring frame and a lower support leg. The sewage collection bowl is located below the cleaning bowl group and is used to collect dirt generated by scrubbing the spherical monitoring probe; the lower support leg supports the ring frame, and the bowl mouth of the sewage collection bowl is detachably connected to the ring frame, and the first petal, the second petal and the third petal are each connected to the ring frame through the upper support leg.

[0007] Furthermore, the nozzle on the second petal is connected to the cleaning liquid extrusion assembly, and the cleaning liquid extrusion assembly includes a vertically installed liquid storage cylinder, the piston in the liquid storage cylinder is connected to the injection rod, the suction port at the bottom of the liquid storage cylinder is connected to the first pipe port of the three-way pipe, the second pipe port of the three-way pipe is connected to the cleaning liquid tank through the liquid suction pipe, and the third pipe port is connected to the nozzle through the liquid injection pipe. A No. 1 check valve is installed at the second pipe port of the three-way pipe, and a No. 2 check valve is installed at the third pipe port; a reaction frame is provided on the column, which can apply a reverse thrust to the injection rod so that the piston squeezes the liquid in the liquid storage cylinder.

[0008] Furthermore, a spherical monitoring probe is installed on the swivel seat of the column, and 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, and a belt is connected between the driving pulley and the driven pulley; the start-stop control component of the servo motor is linked to the lifting mechanism, and when the lifting mechanism lifts the cleaning mechanism to the set height, the start-stop control component connects the circuit of the servo motor.

[0009] Furthermore, the start-stop control assembly includes a control switch, a trigger block, a boom, an elastic telescopic rod and a shift rod; the boom is fixed on the column, the trigger block is slidably sleeved on the boom through a horizontal through slot, the elastic telescopic rod is supported between the trigger block and the boom in the horizontal through slot, the shift rod is fixedly connected to the trigger block, and the sliding cap at the end of the shift rod is hinged to the shift piece of the control switch; a collision block is provided on the working end of the lifting mechanism, and chamfers are provided on the colliding sides of the collision block and the trigger block. When the collision block rises, it pushes the trigger block away, thereby pushing the control switch to open. After the collision block drops, the elastic telescopic rod pushes the trigger block to reset, and the control switch is closed.

[0010] Furthermore, the lifting mechanism includes a screw rod, a screw rod nut and a supporting bracket; the screw rod is rotatably installed in the axial hole in the center of the column, and a set of slides are opened on the column in front and behind the screw rod, the slides are connected to the axial hole, and the screw rod nut is screwed with the screw rod in the axial hole. A slider corresponding to the slide is fixed on the screw rod nut, and the slider slides in engagement with the slide. The supporting bracket is connected to the slider, and the rotation of the screw rod drives the screw rod nut to move up and down with the supporting bracket, and the cleaning mechanism is mounted on the supporting bracket.

[0011] Furthermore, the screw rod inputs torque from the hand-cranked turntable at the bottom of the column, the bottom end of the screw rod is installed with a driven bevel gear, and the driving bevel gear is installed on the rotating shaft of the hand-cranked turntable, and the driven bevel gear and the driving bevel gear are meshed.

[0012] Furthermore, the bearing bracket includes a bearing beam and a bearing platform. A vertical socket is opened on the slider. The bearing beam is hung on the slider through a pin and the socket. The bearing platform is placed on the bearing beam in front and behind the column. The cleaning mechanism is arranged on the top surface of the bearing platform.

[0013] Furthermore, the first petal and the third petal are elastic. When the cleaning bowl group does not contact the spherical monitoring probe, the lower ends of the first petal and the third petal are retracted toward the middle. When the cleaning bowl group contacts the spherical monitoring probe, the spherical monitoring probe stretches the first petal and the third petal apart, and a distance is always reserved between the second petal and the spherical monitoring probe.

[0014] Furthermore, slots are opened on the opposite surfaces of the two supporting beams, and the slots include an entrance section, a limiting section and an installation section; two wing plates are provided on the cleaning liquid tank, which respectively engage with the slots on the supporting beams on both sides. The wing plates are pushed into the entrance section of the slots, pass through the limiting section, and fall into the installation section. The steps between the limiting section and the installation section prevent the wing plates from falling out.

[0015] Compared with the prior art, the advantages of the present invention are: Through the coordinated work of the lifting mechanism and the cleaning mechanism, the cleaning bowl group can be accurately transported to each spherical monitoring probe position without manual climbing and wiping; the cleaning bowl group (first petal, second petal, third petal) completes the cleaning, spraying and scraping operations in sequence with the cooperation of the spherical monitoring probe rotation (driven by the torque output mechanism). The entire process is automated, greatly reducing the frequency and intensity of manual operations; and avoiding the safety risks of workers performing cleaning operations at high altitudes and in complex construction environments.

[0016] The cleaning bowl completely covers the probe and rotates relative to it when the probe rotates, ensuring that the bristles, cleaning fluid, and wiper strips can contact and clean all areas of the sphere surface without blind spots; the elastically designed first and third petals can automatically adapt to the size of the sphere, ensuring that the bristles and wiper strips fit tightly to the spherical surface, improving the cleaning effect; the spraying (second petal) and wiping (third petal) operate continuously, effectively removing stubborn stains and quickly clearing residual water stains to keep the lens clear.

[0017] A specially designed wastewater collection bowl, located directly below the cleaning bowl assembly, effectively collects wastewater and dirt generated during scrubbing and spraying, preventing dripping and contaminating equipment or the floor below. The wastewater collection bowl is detachably connected to the ring stand for easy, regular cleaning of collected wastewater and dirt.

[0018] Through innovative mechanical structure and linkage control, the device successfully achieves automatic, efficient and no-dead-angle cleaning of spherical monitoring probes at construction sites, effectively solving the problems of inconvenience, low efficiency and high risk of manual cleaning. At the same time, it has the advantages of energy saving, sewage collection and convenient maintenance, which significantly improves the maintenance efficiency and operational reliability of monitoring equipment.

DETAILED DESCRIPTION

[0021] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the following briefly introduces the drawings required for use in the embodiments or the description of the prior art. Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative work.

[0022] like Figure 1 、 Figure 2 、 Figure 10 As shown: A spherical monitoring probe cleaning device for a construction site, comprising a column 1, a spherical monitoring probe 2, a lifting mechanism 3 and a cleaning mechanism 4; 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; The cleaning mechanism 4 includes a cleaning bowl assembly aligned vertically with the spherical monitoring probe 2. Each cleaning bowl assembly includes a first flap 4.1 with bristles, a second flap 4.2 with a nozzle, and a third flap 4.3 with a wiper. The cleaning bowl assembly cover rotates relative to the spherical monitoring probe 2. The first flap 4.1, the second flap 4.2, and the third flap 4.3 respectively clean, spray, and wipe the spherical monitoring probe 2. The cleaning mechanism 4 is lifted to the position of the spherical monitoring probe 2 by the lifting mechanism 3, and the cleaning bowl group of the cleaning mechanism 4 covers the outside of the spherical monitoring probe 2. When the spherical monitoring probe 2 and the cleaning bowl group rotate relative to each other, the bristles on the first petal 4.1 brush the surface of the spherical monitoring probe 2 in a circle, the nozzle on the second petal 4.2 sprays cleaning liquid to spray the surface of the spherical monitoring probe 2 in a circle, and the wiper strip on the third petal 4.3 scrapes away the water droplets remaining on the surface of the spherical monitoring probe 2; the entire process is automated, which greatly reduces the frequency and intensity of manual operation.

[0023] Specifically, a top plate 16 is installed on the top of the column 1, a swivel seat 5 is provided on the top plate 16, the spherical monitoring probe 2 is connected to the swivel seat 5, and the spherical monitoring probe 2 is connected to the torque output mechanism, which drives the spherical monitoring probe 2 to rotate.

[0024] The first flap 4.1 and the third flap 4.3 are elastic. When the cleaning bowl group does not touch the spherical monitoring probe 2, the lower ends of the first flap 4.1 and the third flap 4.3 are retracted toward the middle. When the cleaning bowl group touches the spherical monitoring probe 2, the spherical monitoring probe 2 stretches the first flap 4.1 and the third flap 4.3. The elastic design of the first flap 4.1 and the third flap 4.3 can automatically adapt to the size of the sphere, ensuring that the bristles and the scraper strip fit closely to the spherical surface, thereby improving the cleaning effect; the second flap 4.2 always reserves a distance from the spherical monitoring probe 2 so that the cleaning fluid sprayed from the nozzle can spread.

[0025] like Figure 7 、 Figure 8 、 Figure 9 As shown, the cleaning mechanism 4 also includes a sewage collection bowl 4.4, a ring frame 4.5, and a lower support leg 4.6. The sewage collection bowl 4.4 is located below the cleaning bowl assembly and is used to collect dirt generated by scrubbing the spherical monitoring probe 2. The lower support leg 4.6 supports the ring frame 4.5. The bowl mouth of the sewage collection bowl 4.4 is detachably connected to the ring frame 4.5. The first flap 4.1, the second flap 4.2, and the third flap 4.3 are each connected to the ring frame 4.5 via an upper support leg 4.7. The sewage collection bowl 4.4 effectively collects sewage and dirt generated during scrubbing and spraying, preventing dirty water from dripping and contaminating the equipment or ground below. The sewage collection bowl 4.4 is screwed to the ring frame 4.5, facilitating regular cleaning of the collected sewage and dirt.

[0026] The nozzle on the second petal 4.2 is connected to the cleaning liquid extrusion assembly, which includes a vertically mounted liquid storage cylinder 4.8. The piston in the liquid storage cylinder 4.8 is connected to the injection rod 4.9. The suction port at the bottom of the liquid storage cylinder 4.8 is connected to the first pipe port of the three-way pipe 4.10. The second pipe port of the three-way pipe 4.10 is connected to the cleaning liquid tank 4.12 through the liquid extraction pipe 4.11, and the third pipe port is connected to the nozzle through the injection pipe 4.13. A No. 1 check valve is installed at the second pipe port of the three-way pipe 4.10 4.14. A No. 2 check valve 4.15 is installed at the third pipe outlet. A reaction frame is provided on the column 1, which can apply a reverse thrust to the injection rod 4.9, thereby squeezing the liquid in the liquid storage cylinder 4.8 with the piston. The top plate 16 serves as the reaction frame. When the lifting mechanism 3 rises with the cleaning liquid extrusion assembly as a whole, the injection rod 4.9 first touches the top plate 16, and the cleaning liquid extrusion assembly continues to rise. The injection rod 4.9 pushes the piston to squeeze the cleaning liquid in the liquid storage cylinder 4.8, and the cleaning liquid flows through the injection pipe 4.13 and is sprayed out from the nozzle.

[0027] The three-way pipe 4.10 cooperates with the No. 1 check valve 4.14 and the No. 2 check valve 4.15 to ensure that the cleaning liquid can only flow from the liquid reservoir 4.8 to the nozzle and can only be replenished to the liquid reservoir 4.8 from the cleaning liquid tank 4.12, thereby realizing a one-way and reliable liquid supply circulation. When the cleaning mechanism 4 is located at the lower end of the column 1, the injection rod 4.9 is manually lifted, and the negative pressure draws the cleaning liquid in the cleaning liquid tank 4.12 into the liquid reservoir 4.8. When the cleaning liquid flows through the three-way pipe 4.10, due to the negative pressure in the liquid reservoir 4.8, the cleaning liquid will not flow to the injection pipe 4.13. Because of the one-way sealing effect of the No. 2 check valve 4.15, the third pipe opening of the three-way pipe 4.10 will not be depressurized. During the cleaning liquid extrusion process, due to the one-way sealing effect of the No. 1 check valve 4.14, the cleaning liquid cannot flow out from the second pipe opening of the three-way pipe 4.10.

[0028] The cleaning fluid extrusion assembly is cleverly designed. When the lifting mechanism (3) reaches the top, the reverse thrust generated by the ejector rod (4.9) contacting the top plate (16) pushes the piston, 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.

[0029] like Figure 8 、 Figure 11 As shown: the torque output mechanism of the spherical monitoring probe 2 includes a driving pulley 6, a driven pulley 7, a belt 8 and a servo motor 9; the driving pulley 6 is installed on the output shaft of the servo motor 9, and the driven pulley 7 is installed on the spherical monitoring probe 2. The belt 8 is connected between the driving pulley 6 and the driven pulley 7. After the servo motor 9 is started, the spherical monitoring probe 2 is driven to rotate as a whole through the driving pulley 6, the driven pulley 7 and the belt 8. After the servo motor 9 is started, it is set to rotate forward one circle and reverse one circle to prevent the circuit of the spherical monitoring probe 2 from being tangled; the start-stop control component of the servo motor 9 is linked to 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.

[0030] like Figure 12 、 Figure 13As shown: the start-stop control assembly includes a control switch 10, a trigger block 11, a suspension rod 12, an elastic telescopic rod 13 and a toggle rod 14; the suspension rod 12 is fixed to the column 1, the trigger block 11 is slidably sleeved on the suspension rod 12 through a horizontal through slot 11.1, the trigger block 11 is fixed vertically and can slide freely horizontally, the elastic telescopic rod 13 is supported between the trigger block 11 and the suspension rod 12 in the horizontal through slot 11.1, the toggle rod 14 is fixedly connected to the trigger block 11, the sliding cap 14.1 at the end of the toggle rod 14 is hinged to the paddle 10.1 of the control switch 10, and the sliding cap 14.1 is slidably sleeved on the end of the toggle rod 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, and the collision sides of the collision block 15 and the trigger block 11 are both chamfered. When the collision block 15 rises, it pushes the trigger block 11 away, and 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 turn on. After the collision block 15 drops, the elastic telescopic rod 13 pushes the trigger block 11 to reset, and 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 turned off.

[0031] The start-stop control assembly links the cleaning mechanism 4's elevation with the probe's rotation. When the cleaning mechanism 4 reaches the set height (cleaning position), the collision block 15 triggers the control switch 10, activating the servo motor 9 and rotating the probe. When the cleaning mechanism 4 is lowered after cleaning, the servo motor 9 automatically shuts off. This design ensures that the cleaning action (rotation) is initiated only when needed, avoiding inefficient operation, saving energy, and reducing wear. The chamfered corners of the collision block 15 and the trigger block 11 ensure a smooth and reliable triggering and resetting process.

[0032] like Figure 3 、 Figure 4 As shown, the lifting mechanism 3 includes a screw 3.1, a screw nut 3.2, and a supporting bracket. The screw 3.1 is rotatably mounted in the central axial hole 1.1 of the column 1. A pair of slideways 1.2 are provided on the column 1, one in front of and one behind the screw 3.1. The slideways 1.2 are connected to the axial hole 1.1, and the screw nut 3.2 screws into the screw 3.1 within the axial hole 1.1. A slider 3.3 is fixed to the screw nut 3.2, corresponding to each slideway 1.2. The slider 3.3 slides in contact with the slideway 1.2. The supporting bracket is connected to the slider 3.3. Rotation of the screw 3.1 drives the screw nut 3.2, which moves the supporting bracket up and down. The cleaning mechanism 4 is mounted on the supporting bracket. The lifting mechanism 3 is driven by the screw nut 3.2, which cooperates with the slideway 1.2 and slider 3.3 in the column 1. This ensures precise guidance, strong load-bearing capacity, and smooth operation, capable of withstanding the vibration and load of the construction environment. The overall structure relies on the existing column 1 of the monitoring probe, ensuring a stable installation and saving space.

[0033] like Figure 5As shown: the screw rod 3.1 receives torque from the hand-cranked turntable 3.6 at the bottom of the column 1, a driven bevel gear 3.7 is mounted on the bottom end of the screw rod 3.1, a driving bevel gear 3.8 is mounted on the rotating shaft of the hand-cranked turntable 3.6, and the driven bevel gear 3.7 and the driving bevel gear 3.8 are engaged; when the hand-cranked turntable 3.6 rotates, the driving bevel gear 3.8 and the driven bevel gear 3.7 are transmitted, thereby driving the screw rod 3.1 to rotate.

[0034] like Figure 6 、 Figure 7 、 Figure 8 As shown: the load-bearing bracket includes a load-bearing beam 3.4 and a load-bearing platform 3.5, a vertical socket 3.3.1 is opened on the slider 3.3, the load-bearing beam 3.4 is hung on the slider 3.3 through a pin 3.4.1 and the socket 3.3.1, the load-bearing platform 3.5 is placed on the load-bearing beam 3.4 in front and behind the column 1, and the bottom surface of the load-bearing platform 3.5 is provided with a baffle to stop the load-bearing beam 3.4. The two baffles sandwich the two load-bearing beams 3.4 in the middle to prevent the load-bearing platform 3.5 from moving forward and backward, and the end of the load-bearing beam 3.4 is provided with a baffle, which cooperates with the column surface of the column 1 to prevent the load-bearing platform 3.5 from moving forward and backward. The cleaning mechanism 4 is arranged on the top surface of the load-bearing platform 3.5; the load-bearing bracket and the slider 3.3 are connected by a pin, which is convenient for installation and disassembly and maintenance.

[0035] Slots 3.4.2 are defined on opposing surfaces of the two load-bearing beams 3.4. These slots 3.4.2 include an entry section 3.4.2.1, a stopper section 3.4.2.2, and an installation section 3.4.2.3. The cleaning liquid reservoir 4.12 is provided with two flaps 4.12.1, each engaging with the slots 3.4.2 on the load-bearing beams 3.4. The flaps 4.12.1 are pushed through the entry section 3.4.2.1 of the slots 3.4.2, pass through the stopper sections 3.4.2.2, and fall into the installation sections 3.4.2.3. A step between the stopper sections 3.4.2.2 and the installation sections 3.4.2.3 prevents the flaps 4.12.1 from being dislodged. The flaps 4.12.1 engage the slots 3.4.2 of the load-bearing beams 3.4, enabling quick installation and locking, and conveniently changing the cleaning liquid.

Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
