Description

Technical Field

[0001] The present invention belongs to the technical field of paint spraying and coating protection for distribution network transmission line poles, and in particular relates to a handheld intelligent working tool for insulation spraying of transmission line poles. Background Art

[0002] For the exposed points at the line connection positions of the distribution network transmission poles, the existing insulation spraying tools mainly include manual spraying tools and drone spraying tools. When spraying manually, the operator needs to climb to the top of the transmission pole, hold the insulating pole by hand to control the spray head for spraying. This spraying method has high labor intensity and low safety factor. In order to make the paint cover the entire target spraying object, the angle needs to be adjusted many times during the operation, and the paint spraying distance is far, which makes it difficult to ensure the spraying quality.

[0003] In order to improve the efficiency of manual spraying, patent application document CN117065956 A proposes an insulation spraying device for overhead distribution lines and equipment exposed points, which uses a shielding cover to wrap the distribution line or the target exposed point, and sprays the distribution line and equipment exposed point. Although the problem of spraying efficiency has been solved to a certain extent, due to the closed spraying space, it is difficult to monitor the spraying effect during operation, which can easily cause incomplete spraying or over-spraying, resulting in waste of paint. In addition, the size of the shielding cover is fixed, which is difficult to adapt to spraying objects with complex positions and shapes. For example, for targets such as metal crossarms, drop switches, and lightning arrester leads, in order to adapt to spraying targets of different shapes and sizes, the size of the shielding cover needs to be set very large. When approaching the spraying target, the shielding cover is in an open state, which occupies more space. Assuming that multiple crossarms are set up on the top of a certain electric pole, if the middle crossarm is to be sprayed, it may be difficult for the shielding cover to effectively approach and wrap the spraying target. In addition, the orientation of the insulation spray target is also variable. For example, a drop switch is an oblique spray target. Another example is the lead above the lightning arrester. If you want to wrap the target, the support rod needs to be almost horizontal. Obviously, the existing spray tools cannot meet these requirements. Summary of the invention

DETAILED DESCRIPTION

[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

They are relational words determined only for the convenience of describing the structural relationships of the various parts or elements of the present invention. They do not specifically refer to any part or element in the present invention and cannot be understood as limitations on the present invention.

[0023] In the present invention, terms such as "connection" should be understood in a broad sense, indicating that the connection can be fixed, integral or detachable; it can be directly connected or indirectly connected through an intermediate medium. Those skilled in the art can determine the specific meaning of the above terms in the present invention according to specific circumstances, and they should not be understood as limiting the present invention.

[0024] In the absence of conflict, the embodiments of the present invention and the features of the embodiments may be combined with each other.

[0025] One or more embodiments of the present invention provide a handheld intelligent working tool for insulation spraying of transmission line poles, comprising an insulating pole 1, a spraying assembly 2 arranged above the insulating pole 1, and a control module 3 arranged below the insulating pole 1; the spraying assembly 2 comprises a wind shield 4, and a plurality of spray heads 5 are evenly arranged on the inner surface of the wind shield 4; the wind shield 4 comprises a central bottom shield 31, and side shields 32 symmetrically arranged on both sides of the central bottom shield 31 and rotatably connected to the central bottom shield 31; the rotation drive motor of the side shield 32 is connected to the control module 3, and the control module 3 is configured to: control the rotation of the two side shields 32 in response to a control instruction for the rotation of the side shields 32 of the wind shield 4.

[0026] The design of multiple nozzles 5 ensures the uniformity of spraying and improves the spraying efficiency; the setting of the wind shield 4 can block the side wind during spraying to avoid paint pollution. At the same time, the wind shield 4 is set to a semi-enclosed design with adjustable size, which can be adjusted as needed according to the shape and size of the spraying target. Moreover, since the opening of the shielding cover is adjustable, the working tool can also adapt to a small working space. That is, the working tool can adapt to the needs of spraying targets of different shapes and sizes in different spaces, and is more practical.

[0027] The insulating rod 1 is provided with one or more sections. Specifically, both ends of the insulating rod 1 are threaded metal connecting pipes, which can be connected and lengthened section by section according to the on-site operation conditions.

[0028] To ensure the shielding effect, the central bottom cover 31 and the side cover 32 both have side guard plates extending in the direction of the opening of the wind shield 4. In addition, in order to allow the wind shield 4 to have a larger adjustment space, a certain angle is reserved between the side guard plates on the same side of the central bottom cover 31 and the side cover 32 of the wind shield 4, or a certain spacing is provided so that when the side cover 32 rotates inward relative to the central bottom cover 31, the adjacent side guard plates can be staggered, so that the side cover 32 can have a larger rotation space, making the minimum enclosed area smaller, and having better adaptability to narrow spraying operation spaces, and it is also conducive to avoiding obstacles when the spraying assembly 2 approaches the target spraying point, for example, approaching the spraying target with a smaller opening, and adjusting to a suitable opening to enclose the spraying target when it reaches the vicinity of the spraying target.

[0029] Since multiple nozzles 5 are arranged in the wind shield 4, when the side cover 32 of the wind shield 4 rotates with a large amplitude, it does not cause a significant impact on the spraying direction of the nozzle 5. Multiple nozzles 5 cannot point to a central point at the same time, which has a little impact on the spraying effect. For example, assuming that two nozzles 5 are respectively provided on the two side covers 32, as the rotation amplitude of the side covers 32 increases, the intersection of the spraying directions of the two nozzles 5 above the two side covers 32 and the intersection of the spraying directions of the two nozzles 5 below will gradually move away, resulting in the inability to effectively spray multiple angles of the same object at the same time. In order to solve the above problems, in some embodiments, the spraying angles of the multiple nozzles 5 are adjustable, and the angle adjustment motors of the multiple nozzles 5 are connected to the control module 3, and the direction of the nozzle 5 can be adjusted as needed via the control module 3. Therefore, after the opening size of the wind shield 4 is determined, the angle can be adjusted so that the spray direction of each nozzle 5 points to the target spraying part, all nozzles 5 are distributed in a circle about the target spraying part, and the combined spray angle is greater than or equal to 360 degrees, thereby improving the coverage of the spraying, reducing the blind spots of the spraying and the workload of the workers' arms to adjust during the spraying operation.

[0030] In addition, each of the nozzles 5 is also provided with a flow switch, which can adjust the spray amplitude. The adjustment switch can be manual or electric, and is controlled by a motor, so that the flow rate of the paint can be adjusted according to the exposure of the target spraying area to avoid paint waste.

[0031] In order to reduce the complexity of operation and avoid repeated adjustments due to lack of expertise or inaccurate alignment due to manual errors when adjusting the angle of the nozzle 5, in some embodiments, a method for adaptively adjusting the spray angles of the multiple nozzles 5 based on the opening size of the wind shield 4 is also provided. Specifically, the control module 3 is configured to: respond to the control instruction of the rotation of the side cover 32 of the wind shield 4, control the rotation of the two side covers 32; according to the rotation angle size, based on the preset corresponding relationship between the rotation angle of the side cover 32 of the wind shield 4 and the spray angles of the multiple nozzles 5, obtain the target angles of the multiple nozzles 5, and control the multiple nozzles 5 to rotate so that the spray directions of the multiple nozzles 5 are all toward the center of the wind shield 4. It can be understood by those skilled in the art that multiple adjustable angles of the wind shield 4 can be preset, such as -10°, -5°, 0°, 5°, and 10°, 0° represents the initial state, a negative number represents that the two side covers 32 rotate inward at the same time, and a positive number represents that the two side covers 32 rotate outward at the same time. At the same time, the angles of each nozzle 5 at each rotation angle are calibrated.

[0032] By associating the spray angles of multiple nozzles 5 with the opening size of the wind shield 4, the spray angles of the wind shield 4 and the nozzles 5 are linked and adjusted, so that the spray directions of the multiple nozzles 5 always converge at one point. Therefore, there is no need to adjust the position of the spraying component 2, and synchronous operation of various angles of the spraying target can be achieved, thereby improving working efficiency and spraying effect.

[0033] However, the above-mentioned working tool cannot adapt to inclined spraying targets. In order to overcome this defect, in some embodiments, a dual-axis rotation assembly 6 is arranged between the insulating rod 1 and the spray assembly 2, and the dual-axis rotation assembly 6 includes a first single-axis rotation mechanism 33 and a second single-axis rotation mechanism 34 connected up and down, and the rotation axes are respectively along the x-axis and the y-axis. As an example, one end of the first single-axis rotation mechanism 33 and the second single-axis rotation mechanism 34 that realize rotation is recorded as the active end, and the other end is recorded as the driven end. The upper end of the insulating rod 1 is rotationally connected to the active end of the first single-axis rotation mechanism 33, the driven end of the first single-axis rotation mechanism 33 is rotationally connected to the active end of the second single-axis rotation mechanism 34, and the driven end of the second single-axis rotation mechanism 34 is connected to the central bottom cover 31 of the wind shield 4. A motor is provided on the rotating shaft of the first single-axis rotating mechanism 33 and the second single-axis rotating mechanism 34, so that the dual-axis rotating component 6 can realize two axial rotational degrees of freedom. Combined with the rotational degrees of freedom of the construction worker's wrist (Z-axis), the spray component 2 can be omnidirectionally rotated and adjusted in three-dimensional space, and the spraying direction can be omnidirectionally adjusted, so that the spraying tool can not only adapt to spraying objects of different orientations and shapes, but also adapt to spraying objects of different angles, such as oblique drop switches, vertical lightning arrester leads, wire clamps, pole switches, PTs, jumpers, etc. The spray component 2 can be controlled to rotate relative to the insulating rod 1, thereby surrounding the spraying target.

[0034] The spraying operation of the spraying assembly 2 adopts the negative pressure siphon spraying principle: the nozzle 5 adopts a siphon nozzle 5, which has two interfaces, one connected to the air compressor 11, and the other connected to the paint box. During the spraying operation, a certain pressure of gas is supplied to the front end of the nozzle 5 based on one of the interfaces, and a negative pressure is generated in the front end area of ​​the nozzle 5. Then, through another interface, the paint in the paint bucket 12 is adsorbed to the nozzle 5 and sprayed out. At the same time, the paint will be atomized by the air, which can improve the atomization effect. Specifically, each of the nozzles 5 has two interfaces, which are connected to the air compressor 11 and the paint bucket 12 via the air pipe 7 and the paint pipe 8 respectively; the insulating rod 1 is hollow inside, and the air pipe 7 and the paint pipe 8 pass through the bottom of the insulating rod 1 from the inside. A connecting block 15 is provided at the bottom of the insulating rod 1, and a through hole adapted to the air pipe 7 and the paint pipe 8 is provided on the connecting block 15.

[0035] The control module 3 includes a housing, the back plate of which is connected to the insulating rod 1 through a connecting device; a first control board 29 is arranged in the housing, as well as a wireless communication module and a battery module 28 connected to the first control board 29. The first control board 29 is connected to the rotating mechanism of the side cover 32 of the wind shield 4, the two driving motors of the dual-axis rotating assembly 6, and the driving motors of the plurality of nozzles 5.

[0036] The first control panel 29 is connected to the ground remote controller via a wireless communication module. The ground remote controller can remotely control the size of the windshield 4 and the rotation angles of the two single-axis rotation mechanisms in the dual-axis rotation assembly 6. As an example, the ground remote controller is provided with X-axis and Y-axis rotation buttons, both of which are connected to the first control panel 29. Each time one of the rotation buttons is pressed, the device rotates by a certain angle.

[0037] The air compressor 11 and the paint bucket 12 are both arranged in the transfer device 10. The transfer device 10 includes a shell, and the paint pipe 8 section in the shell is provided with a first solenoid valve 16; the shell also includes a second control panel and a power module. A control panel 17 is provided on one side of the shell; the control panel 17 is provided with a main power switch, a main power socket, a status indicator light, an air pump switch and a main paint switch. The second control panel is respectively connected to the main power switch, the air pump switch, the main paint switch and the first solenoid valve 16, and is used to receive instructions such as power on, air compressor 11 on and off, and paint pipe 8 on and off issued by the user through the control panel 17. The main power socket is connected to the power module. When the air compressor 11 is working, if the air inlet solenoid valve is opened, the air inlet pipe is always inlet, providing the feed pipe with a siphon force for feeding. The air outlet of the air compressor 11 also has a flow regulating valve and a drying filter, which can set the pressure and flow of the outlet gas, and then the flow and spray amplitude of the spray can be manually adjusted, and the moisture in the air can be removed to ensure insulation safety. Traveling wheels 14 are provided under the shell body to facilitate transportation to the spraying location, filling of paint, etc.

[0038] By setting up a ground remote control, a transfer device 10, and setting an operation switch on the transfer device 10, the staff responsible for climbing the pole can hold the operation tool and focus on the spraying operation, and the cooperating staff on the ground assist in switching to control the posture of the spray component 2 of the operation tool, the size of the wind shield 4, etc.

[0039] The first control board 29 in the control module 3 is independently powered by a lithium battery and is not connected to the second control board in the transfer equipment 10 by any cable line. At the same time, the air pipe 7, the paint pipe 8 and the insulating medium (dry air, insulating paint) inside them are insulated. The monitoring video collected by the camera is transmitted via a cable and stored in the storage device of the control module 3. Insulation isolation is formed between the spray assembly 2 and the control module 3 and the transfer equipment 10 on the ground, ensuring the safety of the live spraying operation and preventing discharge to the ground. Since each pole climbing does not necessarily involve spraying only one target, the pole climbing staff needs to close the paint passage after completing the spraying of one target, and then open it again after aligning the next target. In order to facilitate the pole climbing staff to complete this work by themselves, in some embodiments, the insulating rod 1 is provided with openings above and below the control module 3, which are respectively recorded as the first opening 18 and the second opening 19. The paint tube 8 extends from the opening below the second opening 19, passes through the control module 3, and then connects to the insulating rod 1 through the first opening 18; the paint tube 8 section located in the control module 3 is also provided with a second solenoid valve 23, which is connected to the first control board 29, and the control module 3 is also provided with a manual control switch 24 of the second solenoid valve 23. In this way, after the ground staff helps to open the paint switch, the pole climbing staff can also perform on-off control as needed, which is more flexible. Of course, the second solenoid valve 23 can also be controlled via the ground remote controller, which is provided with a spray button, and sends a spray command to the first control board via the wireless communication module. After the first control board 29 receives the command to execute spraying, it controls the second solenoid valve 23 to open via the first control board 29. As an example, the second solenoid valve 23 can be a two-position three-way solenoid valve, which can be remotely controlled by the ground remote controller, or directly controlled from the near end via the control module 3, thereby realizing the on-off control of the paint pipe 8.

[0040] It can be understood that the main spray switch on the transfer equipment 10 is the main switch of the spray pipeline, which is used to control the first solenoid valve 16. The spray switch on the ground remote control and the manual control switch on the control module 3 are used to control the second solenoid valve 23. The three methods complement each other. Both the ground and the climbing pole staff can configure the on and off of the spraying of the paint. At the same time, when the ground staff is required to control the spraying, if the spray switch on the ground remote control fails, it can also be controlled by the main spray switch.

[0041] The upper and lower surfaces of the shell of the control module 3 are provided with pipeline inlet and outlet interfaces. Among them, the interface of the paint pipe 8 below the control module 3 is recorded as the inlet joint 26, and the interface of the paint pipe 8 above the control module 3 is set as a multi-way joint 25, which is used to connect with the multiple nozzles 5 respectively. Similarly, the air pipe 7 also extends from the second opening below the control module 3, passes through the control module 3, and then connects to the insulating rod 1 through the first opening 18. At the same time, the interface of the air pipe 7 above the control module 3 is set as a multi-way joint 25, which is used to connect with the multiple nozzles 5 respectively.

[0042] Since there will be splashed paint during the spraying process, and the wind shield 4 has a certain collection function, in order to avoid the waste of these excess paints, in some embodiments, a paint recovery function is also provided. As a specific implementation method, the bottom of the wind shield 4 is provided with an opening, and the transfer device 10 is also provided with a recovery bucket 13, and the opening and the recovery bucket 13 are connected via a recovery pipe 9. As an example, the insulating rod 1 is close to one end of the spray assembly 2, and an opening is provided on the side, which is recorded as a third opening 20, and a through hole adapted to the recovery pipe 9 is also provided on the connecting block 15 below the insulating rod 1; the recovery pipe 9 enters the insulating rod 1 through the third opening 20, passes through the connecting block 15 below the insulating rod 1, and is connected to the recovery barrel. During spraying, the recovery cover blocks the splashed excess paint, and flows into the recovery pipe 9 through the inclined surface of the recovery cover, and then reaches the recovery bucket 13 below through the recovery pipe 9. Based on the enclosing design of the wind shield 4 and the recovery device, the recovery of splashed paint is realized.

[0043] Since the recovery bucket 13 is stored in the transfer box, in order to timely know the overflow of the recovery bucket 13, a liquid level sensor is also provided in the recovery bucket 13, which is connected to the second control board. A recovery liquid level indicator light is also provided on the control panel 17 of the transfer device 10. The second control board controls the recovery liquid level indicator light to light up according to the signal detected by the liquid level sensor if the liquid level exceeds a set threshold, prompting the user to empty the paint collected in the recovery bucket 13.

[0044] In addition, the main materials of the protective cover and the rotating shaft joint are insulating materials, the rotating shaft motor is protected by an insulating shell on the outside, and the control module 3 and the spray assembly 2 are connected by insulated wires, and the cables pass through the inside of the insulating rod 1. There are only air pipelines and paint pipelines connected between the control module 3 and the transfer assembly, and there is no cable connection, which ensures the phase-to-phase insulation and ground insulation safety during the spraying operation, and meets the ground insulation requirements during 10KV and 35KV live operations.

[0045] In order to facilitate the quick connection between the insulating rod 1 and the transfer device 10, each through hole is provided with a quick connector on the connection block 15 below the insulating rod 1. When in use, the paint pipe 8, air pipe 7 and recovery pipe 9 connected to the transfer device 10 are connected to the corresponding quick connectors to complete the on-site assembly.

[0046] Since the target part of the spraying is blocked by the wind shield 4 during the spraying operation, it is difficult to judge the quality of the spraying, and thus it is difficult to determine the duration of the spraying. Moreover, since the insulating rod 1 has a certain length, if the angle of the rod held by the operator changes slightly, the position of the spraying tool above will be offset, and the wind shield 4 blocks it, making it difficult to detect whether the target part of the spraying deviates from the spraying center. In some embodiments, a camera 21 is arranged above the wind shield 4 via a bracket, and a display module 27 is provided on the control module 3, both of which are connected to the first control board 29. Specifically, the wiring harness of the camera 21 enters the insulating rod 1 through the third opening 20, passes through the first opening 18, and is connected to the control module 3 through the cable connector 30. The shooting direction of the camera 21 is toward the inside of the wind shield 4, and the field of view includes the multiple nozzles 5, which is used to shoot the spraying picture in real time during the spraying process, and assist the spraying operator to determine whether the target part of the spraying is always located at the injection center of the multiple nozzles 5; after the spraying is completed, the quality of the paint surface and the spraying effect can also be visually detected through the display screen.

[0047] During the spraying operation, the ground workers can use the ground remote control to assist the pole climbing workers to adjust the opening size of the wind shield 4 and the posture of the spraying component 2 according to the position and shape of the spraying target part; the pole climbing workers can fine-tune the position of the spraying component 2 in combination with the video images captured by the display screen, so that the spraying target part is located at the injection center of each nozzle 5.

[0048] Specifically, the spraying process includes the following processes: Preparation: (1) Connect the power supply to the conveying component, turn on the main switch of the conveying component, power on the spraying device, and the status indicator light shows normal; (2) After climbing the pole, the pole climbing worker holds the insulating part at the bottom of the insulating pole 1 and lifts the spray assembly 2 to the bottom of the part to be sprayed; (3) The ground staff visually inspects the direction and size of the spraying area, presses the X / Y axis rotation key of the remote control, controls the X / Y axis motor to rotate through the control module 3, adjusts the spraying assembly 2 to rotate to a suitable spraying angle, and adjusts the insulating rod 1 through the wrist so that the wind shield 4 covers the spraying area; (4) The pole climbing operator fine-tunes the position of the spray assembly 2 based on the video images captured by the display screen, so that the spray target area is located at the spray center of each nozzle 5.

[0049] To perform spraying operations: (1) The ground staff turns on the air pump switch on the transfer device 10, and the nozzle 5 of the spray assembly 2 starts to blow air to the spraying area to clean the dust on the spraying area; (2) After the dust is cleaned, turn on the paint switch on the transfer device 10, and the pole climbing operator manually presses the manual spray switch of the control module 3 or the ground staff presses the spray button of the remote control to start the spraying operation. After the spraying part is sprayed, press the paint switch on the transfer device 10 or the button on the remote control to stop spraying; After finishing spraying one part, repeat the above preparation and spraying operation to spray the next part.

[0050] The protection scope of the present invention is limited only by the claims. With the help of the teachings of the present invention, those skilled in the art will easily recognize that alternative structures of the structures disclosed in the present invention can be used as feasible alternative embodiments, and the embodiments disclosed in the present invention can be combined to generate new embodiments, which also fall within the scope of the appended claims.
