DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in combination with the specific embodiments of the utility model and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] The technical solutions provided by various embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0028] Reference Figures 1 to 7 As shown, an embodiment of the utility model provides a tunnel electromechanical equipment dust removal robot for removing dust from the surface of parts to be dusted, including a bridge 1 distributed along the direction of the tunnel, and a robot body 2 driven to walk along the bridge 1, the robot body 2 includes a self-driving mechanism (the movement of the robot body 2 is achieved by the self-driving mechanism, and the self-driving mechanism is a prior art, not shown in the figure) and a connecting seat 21 arranged on the outside of the self-driving mechanism, the robot obtains driving power through the power supply and communication cables laid in the bridge 1, the bridge 1 provides power supply and communication support for the robot on the one hand, and can also provide power and communication for other electromechanical equipment.

[0029] like Figure 1 As shown, a multi-axis robot arm 22 is installed on the connecting seat 21, and a dust removal mechanism 3 is installed at the execution end of the multi-axis robot arm 22. The multi-axis robot arm 22 cooperates with the self-driving mechanism to adjust the spatial position of the dust removal mechanism 3 so that the dust removal mechanism 3 moves to the surface of the part to be dusted (such as the light-emitting surface of the lamp and the lens of the tunnel camera);

[0030] like Figure 2 and Figure 4 As shown, the dust removal mechanism 3 includes a blowing assembly 31 and at least one brush 32 that is driven to rotate by power. According to investigations, the dust components on the surface of equipment in the tunnel are mainly soil particles and fine carbon particles, of which soil particles account for about 95%. Therefore, cleaning of dust does not require cleaning solvents, and the purpose of removing dust can be achieved by using only mechanical force. The brush 32 contacts the surface of the dust-removed part or the electromechanical equipment to be dust-removed, and the brush 32 rotates to wipe the dust on the surface of the dust-removed part, and cooperates with the blowing assembly 31 to blow off the dust, thereby improving the dust removal effect.

[0031] The robot can remove dust from the surface of electromechanical equipment in the tunnel without interfering with normal traffic, reducing the impact of dust on equipment performance. The robot can greatly improve the efficiency of dust removal from equipment in the tunnel, realize the automation of equipment dust removal, and complete the operation automatically without human intervention, completely avoiding the impact of equipment cleaning on tunnel traffic and improving the safety of maintenance operations.

[0032] In some practical applications, a force sensor may be configured so that the contact between the brush 32 and the surface of the device can meet the requirement of removing dust without causing mechanical impact on the device.

[0033] In one embodiment:

[0034] like Figures 2 to 7 As shown, the dust removal mechanism 3 also includes a base 33, a cavity 331 is provided inside the base 33, and at least one group of air outlets 332 are formed at one end of the base 33 having a brush 32; the blowing assembly 31 includes an air pump 311, and a plurality of high-pressure air nozzles 312 installed at the air outlets 332, the air pump 311 is installed in the cavity 331, and the exhaust end of the air pump 311 is connected to the plurality of high-pressure air nozzles 312 through an air pipe, and the air flow is ejected by the high-pressure air nozzle 312 and directed to the brush 32 through the air outlet 332.

[0035] The air pump 311 exhausts air to a plurality of high-pressure air nozzles 312 so that the high-pressure air nozzles 312 can spray out high-pressure airflow, which can blow off the floating dust remaining on the surface of the equipment after the brush 32 scrubs the surface of the equipment, thereby improving the dust removal effect of the electromechanical equipment in the tunnel.

[0036] In another embodiment:

[0037] The air outlet 332 is configured as an inverted cone (such as Figure 3 As shown in the figure, the end of the air outlet 332 close to the base 33 with the brush 32 is an open end, and a plurality of high-pressure air nozzles 312 are installed at the inner bottom end of the air outlet 332; since the air outlet 332 is configured as an inverted cone with two inclined side walls, when the air flow is ejected from the high-pressure air nozzle 312, the air flow can diffuse outward along the inclined side walls of the air outlet 332, thereby expanding the range of the air flow impact on the surface of the equipment and improving the dust removal effect of the high-pressure air flow.

[0038] Specifically, the brush 32 includes a rotating disk 321 and a plurality of soft bristles 322 located at the outer end of the rotating disk 321. The inner end of the rotating disk 321 is coaxially connected with a rotating shaft 323. The rotating shaft 323 passes through the base 33 to the cavity 331 and rotates with the base 33. In this case, the bristles 322 will bend and expand after contacting the surface of the device. When the brush 32 rotates, the area of ​​the bristles 322 contacting the surface of the device can be expanded, so that the dust on the surface of the device can be completely brushed away by the bristles 322, avoiding dust residue in dead corners.

[0039] In another preferred embodiment:

[0040] like Figure 4 and Figure 6 As shown, the several bristles 322 on each brush 32 are distributed obliquely toward the outer side of the circumference of the rotating disk 321, so that the brush 32 can contact the device over a large area when it just contacts the surface of the device. Compared with straight bristles 322, there is no need to give the bristles 322 an additional pressure to deform and bend the bristles 322, which can improve the dust removal effect of the bristles 322 while avoiding excessive pressure of the bristles 322 on the device surface, thereby causing wear on the device surface.

[0041] Specifically, in some practical applications, six brushes 32 are configured and are evenly spaced on the base 33. The six brushes 32 correspond to each other in pairs to form three groups of brush groups 34. The air outlets 332 are configured in a plurality and one air outlet 332 is arranged between each adjacent brush group 34. A sub-gear 35 is fixedly sleeved on the two rotating shafts 323 in each group of brush groups 34, and a main gear 36 is arranged between the two sub-gears 35 to drive the rotation. A rotation driving source 37 is also provided in the cavity 331, and a pulley 38 is fixedly sleeved on the end of the gear shaft 361 of each main gear 36. Two adjacent pulleys 38 are connected for transmission by a transmission belt 39, and the output shaft of the rotation driving source 37 is coaxially fixedly connected with one of the gear shafts 361.

[0042] In this embodiment, by operating the rotating drive source 37, through the transmission of multiple pulleys 38, main gears 36 and sub gears 35, multiple brushes 32 can be driven to rotate synchronously, which can reduce the cost of the drive source and the energy consumption during the driving process.

[0043] In addition, based on the above-mentioned embodiments, a camera and a laser rangefinder may be provided on the base 33 to locate the spatial coordinates of the surface of the device through intelligent image analysis technology, thereby improving the dust removal accuracy of the device.

[0044] During non-dust removal periods, the base 33 can be installed with other monitoring equipment (such as high-definition cameras) to conduct intelligent inspections on the tunnel operation status. In the event of a fire, the base 33 can be installed with a thermal camera to remotely view the situation at the fire scene and provide information support for rescue work. The function of the dust removal robot can be expanded, and the base 33 can be installed with different monitoring equipment to conduct intelligent inspections on the tunnel operation status.

[0045] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
