Description

Technical Field

[0001] This utility model belongs to the technical field of power plant inspection devices, specifically relating to an inspection robot used in new energy power plants. Background Technology

[0002] As a core component of clean energy systems, the operational safety of new energy power plants directly impacts their stable power supply and economic benefits. Because new energy power plants contain a large number of electrical equipment such as inverters, switchgear, photovoltaic modules, wind turbine electrical cabinets, and transmission lines, their dense layout and highly concentrated energy make them prone to fires during long-term operation due to equipment aging, localized overheating, cable short circuits, or poor connections. If a fire is not controlled in time, it can lead to damage to electrical equipment, the spread of the fire, and in severe cases, paralysis of the power plant system, resulting in huge economic losses. Therefore, it is necessary to use inspection equipment to monitor the operating status of electrical equipment in real time to identify potential safety hazards and prevent accidents.

[0003] To meet the aforementioned inspection needs, existing technologies have developed inspection robots for new energy power plants. The mainstream technical solution is a land-based design: a mobile vehicle serves as the carrier, equipped with monitoring cameras or image acquisition devices. The robot moves along a preset trajectory (such as ground rails, magnetic strips, or planned paths) between or around electrical equipment, collecting data such as images of the equipment's operation to monitor its status. This type of land-based inspection robot can perform preliminary identification of surface defects and operational anomalies in electrical equipment, and has found some application in basic inspection scenarios for new energy power plants.

[0004] However, existing land-based inspection robots have significant technical shortcomings in practical applications, specifically:

[0005] Limited monitoring range and blind spots: Because the movement path of the land-based robot depends on the ground space, and the detection angle of its onboard monitoring equipment (such as cameras) is easily blocked by the main structure of the front electrical equipment (such as cabinets, brackets, component arrays), the effective monitoring range of a single working point is compressed; when the inspection robot is in the inspection area corresponding to the front electrical equipment, if the rear electrical equipment experiences an anomaly such as fire, local overheating, or component failure, the abnormal signals (such as flames, smoke) generated cannot be captured by the robot in time, forming a monitoring blind spot and causing a delay in anomaly detection;

[0006] Delayed emergency response exacerbates safety risks: Due to the existence of the aforementioned monitoring blind spots, abnormalities in the rear electrical equipment are often only detected after they have developed to a certain extent (such as a fire spreading to the front equipment and generating a large amount of smoke), by which time the best opportunity for emergency response has been missed; moreover, the existing land-based inspection robots only have data collection and status monitoring functions and do not have proactive emergency response capabilities. After an anomaly is detected, manual intervention is required to handle it on-site, further prolonging the emergency response time and easily leading to the escalation of accidents. This cannot meet the high requirements of new energy power plants for the timeliness and safety of inspections.

[0007] Based on the shortcomings of the existing technologies, there is an urgent need to develop new inspection robots for the operation and maintenance of new energy power plants. This is to overcome the monitoring blind spots of land-based inspection robots, improve the comprehensiveness of inspection coverage and the timeliness of anomaly detection, thereby ensuring the operational safety of new energy power plants and reducing accident risks and economic losses. Utility Model Content

[0014] Furthermore, the bottom of the receiving cavity is provided with a support ring for supporting the rotating unit, and the support ring is detachably connected to the bottom of the power station roof;

[0015] Furthermore, the rotating unit includes a rotating motor, which is embedded in the top of the receiving cavity and detachably connected to the power station roof via a motor mounting base. The power output shaft of the rotating motor is set vertically downward and connected to the rotating disk via a coupling. The rotating disk is mounted on a support ring and is rotatably connected to the support ring via several rollers.

[0016] Furthermore, the moving unit includes a transverse constraint guide rail for fixing to the bottom of the rotating disk. The transverse constraint guide rail is provided with a moving trolley that can move along the length extension direction of the transverse constraint guide rail. The bottom of the moving trolley is provided with a connecting post extending to the outside of the transverse constraint guide rail. The bottom end of the connecting post is fixed with a guide slider that can move along the length direction of the transverse constraint guide rail.

[0017] Furthermore, each end of the lateral constraint guide rail is provided with a limit contact for limiting the movement of the trolley;

[0018] Furthermore, the camera unit includes a side plate for fixing to the bottom of the guide slider, and a camera for monitoring the new energy power plant is provided on the lower outer side of the side plate;

[0020] Furthermore, the main body of the inspection robot also includes a fire extinguishing bomb auxiliary delivery unit, which includes an electric push rod. The electric push rod is fixed to the side wall of the guide slider through a mounting base. A flexible metal wire is fixed on the telescopic end of the electric push rod, and the bottom of the flexible metal wire is provided with a hook for engaging with the safety pull ring on the fire extinguishing bomb.

[0021] Furthermore, the main body of the inspection robot also includes a fire extinguishing bomb anti-drop unit, and a back plate is provided between the two side uprights, with the fire extinguishing bomb anti-drop unit installed on the back side of the back plate;

[0022] The fire extinguishing bomb anti-fall unit includes a power motor, which is fixed to the rear side of the back plate via a motor mounting plate. A swing arm is mounted on the power output shaft of the power motor, and a support plate for supporting the fire extinguishing bomb is fixed to the end of the swing arm.

[0023] The beneficial effects of this application compared to the prior art are:

[0024] This utility model addresses the technical shortcomings of existing land-based inspection robots, such as significant monitoring blind spots, delayed emergency response, and lack of proactive handling capabilities. By optimizing the installation position, motion structure, and functional module design of the inspection robot, it brings the following beneficial effects:

[0025] 1. This utility model integrates the inspection robot into the bottom of the power station roof, eliminating the dependence of existing land-based robots on ground paths and avoiding the problem of front-row electrical equipment obstructing the monitoring view from a spatial perspective. On one hand, the rotating unit can drive the inspection body to rotate circumferentially, covering electrical equipment in different locations within the power station; on the other hand, the lateral movement unit can drive the inspection body to move laterally, working in conjunction with the dual camera units positioned on either side of the fire extinguishing bomb deployment unit to provide comprehensive monitoring of front and rear inverters, switchgear, photovoltaic modules, and other electrical equipment. This effectively captures abnormal signals such as fires, localized overheating, and component failures in the rear equipment, completely solving the problems of limited single-point monitoring range and blind spots in the rear equipment in existing technologies, significantly improving the timeliness of anomaly detection.

[0026] 2. Based on the inspection function, this utility model adds a fire extinguishing bomb delivery unit, a fire extinguishing bomb auxiliary delivery unit, and a fire extinguishing bomb anti-drop unit, forming an integrated "monitoring-response" inspection system. When the camera unit detects an anomaly, the fire extinguishing bomb delivery unit can release the fire extinguishing bomb by de-energizing the electromagnet. The electric push rod of the auxiliary delivery unit can pull the fire extinguishing bomb safety ring to ensure reliable triggering. The support plate of the anti-drop unit can prevent the fire extinguishing bomb from accidentally falling when not in the delivery state. This design completely solves the defects of existing land-based robots that can only collect data and require manual on-site handling, realizing "instant detection and rapid handling" of anomalies such as fires, greatly shortening the emergency response time, effectively curbing the spread of accidents, and meeting the high requirements of new energy power plants for inspection safety and timeliness.

[0027] 3. This application proposes a fire extinguishing grenade delivery device for use in new energy power plants. Considering that some fire extinguishing grenades require active activation before use, such as pulling the safety ring on the grenade body before throwing, the grenade body will automatically explode after a 6-second reaction time. To address the working characteristics of such fire extinguishing grenades, an auxiliary delivery component is designed in the delivery device. This component consists of an electric push rod and a hook structure. During operation, the hook is attached to the safety ring on the grenade body. When the fire extinguishing grenades are clamped, the electric push rod pulls the hook structure in the opposite direction, causing the safety ring to detach from the grenade body under the pulling force. Once the safety ring is detached, the grenade body has entered the preparation stage for explosion. Then, it only needs to be thrown into the fire area within the reaction time (approximately 6 seconds). Compared to passive fire extinguishers, this type of active fire extinguisher can actively extinguish fires in the early stages, such as when there is smoke or small flames, which is more conducive to ensuring early fire suppression and protecting the safety of internal equipment in the power plant.

[0040] Specific implementation method one: Combining Figures 1 to 11This embodiment describes an inspection robot for use in a new energy power plant. The inspection robot includes a rotating unit for driving the main body of the inspection robot to rotate circumferentially. The rotating unit is installed at the bottom of the power plant roof 1.

[0041] The rotating part of the rotating unit is equipped with a lateral movement unit 5 for driving the main body of the inspection robot to move laterally;

[0042] The main body of the inspection robot is installed on the moving part of the lateral moving unit 5;

[0043] The main body of the inspection robot includes two camera units 6 for monitoring the new energy power plant and a fire extinguishing bomb delivery unit 7. The fire extinguishing bomb delivery unit 7 is installed at the bottom center of the moving part of the lateral moving unit 5. The two camera units 6 are arranged opposite each other on both sides of the fire extinguishing bomb delivery unit 7, and the top of each camera unit 6 is fixedly connected to the bottom of the moving part of the lateral moving unit 5.

[0044] The bottom of the power station roof 1 is machined with a receiving cavity 11 for accommodating the rotating unit;

[0045] The bottom of the receiving cavity 11 is provided with a support ring 2 for supporting the rotating unit, and the support ring 2 is detachably connected to the bottom of the power station roof 1;

[0046] The rotating unit includes a rotating motor 3, which is embedded in the top of the receiving cavity 11 and detachably connected to the power station roof 1 through a motor mounting base. The power output shaft of the rotating motor 3 is set vertically downward and connected to the rotating disk 4 through a coupling. The rotating disk 4 is mounted on the support ring 2 and is rotatably connected to the support ring 2 through several rollers.

[0047] The moving unit 5 includes a transverse constraint guide rail 51 for fixing to the bottom of the rotating disk 4. The transverse constraint guide rail 51 is provided with a moving trolley 52 that can move along the length extension direction of the transverse constraint guide rail 51. The bottom of the moving trolley 52 is provided with a connecting post extending to the outside of the transverse constraint guide rail 51. The bottom end of the connecting post is fixed with a guide slider 54 that can move along the length direction of the transverse constraint guide rail 51.

[0048] The transverse constraint guide rail 51 is provided with a limit contact 53 at each end for limiting the movement of the trolley 52;

[0049] The camera unit 6 includes a side plate 61 for fixing to the bottom of the guide slider 54, and a camera 64 for monitoring the new energy power station is provided on the lower outer side of the side plate 61.

[0050] The fire extinguishing bomb dispensing unit 7 includes a connecting cylinder 71 for fixing to the bottom of the guide slider 54. An electromagnet 72 is installed at the bottom of the connecting cylinder 71. A magnetic block 73 is attracted to the bottom of the electromagnet 72. A fire extinguishing bomb 74 is hung on the magnetic block 73.

[0051] The inspection robot provided in this embodiment abandons the traditional land-based design and instead places the inspection robot on the roof of the power station, thus getting rid of the dependence of existing land-based robots on ground paths. From a spatial perspective, it avoids the problem of front-row electrical equipment obstructing the monitoring view. In this application, the rotating motor 3 drives the rotating disk 4 to rotate. The rotating disk 4 is arranged on the support ring 2 and supported by the support ring 2. In order to reduce the rotational friction between the support ring 2 and the rotating disk 4, two sets of steel balls are added between the support ring 2 and the rotating disk 4. The steel balls optimize the sliding friction between the two into rolling friction. Two sets of annular grooves are machined opposite each other on the top of the support ring 2 and the bottom of the rotating disk 4, and each set of steel balls is set in one set of annular grooves. The passage structure formed by the two oppositely arranged annular grooves ensures the accuracy of the running trajectory of the two sets of steel balls.

[0052] The moving unit 5 is horizontally positioned at the bottom of the rotating disk 4, and its axis corresponds to a straight line with a diameter at the bottom of the rotating disk 4. The main moving device in the moving unit 5 is the moving trolley 52, which is driven by a motor to move back and forth. The top of the moving trolley 52 is equipped with a controller and a mobile power supply 521. The mobile power supply 521 is used to power the motor in the moving trolley 52. ​​To improve the battery life of the mobile power supply 521, an additional external power supply 101 can be mounted on the bottom of the rotating disk 4. At the same time, a wiring groove is machined on the upper part of the outer side of the horizontal constraint guide rail 51 to facilitate the connection between the mobile power supply 521 and the external power supply 101. The length of the connecting wire is 3 / 5 of the maximum travel of the mobile trolley 52. ​​In order to prevent the connecting wire between the mobile power supply 521 and the external power supply 101 from being exposed on the outside, a wire shell can be installed on the side of the external power supply 101 near the mobile unit 5. The connecting wire is contained in the wire shell. In this way, as the mobile trolley 52 moves, the connecting wire can also move freely inside the wire shell, avoiding the connecting wire from falling and getting caught on the inspection robot body at the bottom of the mobile trolley 52, causing an operational accident. The advantage of setting up the external power supply 101 is that the external power supply 101 is exposed, and the staff can replace and charge the external power supply 101 regularly to ensure the continuous operation of the device.

[0053] Each end of the transverse constraint guide rail 51 is provided with a limit contact 53. Simultaneously, a contact switch is provided at each of the front and rear ends of the moving trolley 52. ​​When the trolley reaches the end of the transverse constraint guide rail 51, the contact switch contacts the limit contact 53, controlling the rotation direction of the motor from forward to reverse, thereby changing the trolley's direction of movement. A guide slider 54 is located below the moving trolley 52 to connect to the main body of the inspection robot. To ensure the working stability of the guide slider 54, an auxiliary support guide rail is also provided on the outside of the transverse constraint guide rail 51. The guide slider 54 has a "U"-shaped design and a split structure. The guide slider 54 is fastened to the bottom of the transverse constraint guide rail 51. The horizontal plate portion of the slider 54 is fixedly connected to the connecting column at the bottom of the mobile trolley 52. ​​The two vertical portions of the guide slider 54 are arranged opposite each other on both sides of the horizontal plate portion, and both vertical portions are detachably connected to the horizontal plate portion by bolts. An auxiliary hanging wheel 541 is machined on the upper inner side of each vertical portion. Each vertical portion is hung on the corresponding auxiliary support guide rail by the auxiliary hanging wheel 541, and the auxiliary hanging wheel 541 can reciprocate along the length extension direction of the auxiliary support guide rail. Through the cooperation of the auxiliary hanging wheel 541 and the auxiliary support guide rail, part of the weight of the inspection robot body can be effectively transferred to the horizontal constraint guide rail 51, reducing the operating burden of the mobile trolley 52.

[0054] The main component of the camera unit 6 is a camera 64 used to monitor the new energy power station. The camera 64 is fixed to the lower part of the outside of the side plate 61 by the camera mounting base 63. At the same time, a side power supply 62 for powering the camera 64 is also provided on the upper part of the side plate 61. The staff can replace and charge the side power supply 62 regularly to ensure the stability of the camera 64.

[0055] As an emergency response structure of this application, the fire extinguishing bomb delivery unit 7 can directly deliver fire extinguishing bombs when the camera 64 detects flames or smoke to effectively prevent the spread of fire. The fire extinguishing bomb delivery unit 7 mainly uses magnetic attraction to fix the fire extinguishing bombs at high altitude. The connecting cylinder 71 is equipped with a mobile power supply and controller for supplying power to the electromagnet 72. By controlling whether voltage is applied to the electromagnet 72, the magnetism of the electromagnet 72 is controlled, thereby controlling the attraction state of the electromagnet 72 to the magnetic block 73. Under normal conditions, the electromagnet 72 is magnetic and is used to attract the magnetic block 73. The bottom of the magnetic block 73 is equipped with a fire extinguishing bomb 74, thus enabling the fire extinguishing bomb 74 to be hung at a high place in preparation for delivery. When delivery is required, the electromagnet 72 loses its magnetism, and the magnetic block 73, under the action of losing its attraction force, causes the fire extinguishing bomb 74 to fall freely, realizing the bomb delivery action.

[0056] Specific Implementation Method Two: Combining Figures 1 to 10This embodiment differs from the second specific embodiment in that the main body of the inspection robot also includes a fire extinguishing bomb anti-drop unit 9, and a back plate 10 is provided between the two side upright plates 61. The fire extinguishing bomb anti-drop unit 9 is installed on the back side of the back plate 10.

[0057] The fire extinguishing bomb anti-fall unit 9 includes a power motor 91, which is fixed to the rear side of the back plate 10 via a motor mounting plate. A swing arm 92 is mounted on the power output shaft of the power motor 91, and a support plate 93 for supporting the fire extinguishing bomb 74 is fixed to the end of the swing arm 92. Other components and connection methods are the same as in specific embodiment two.

[0058] In this embodiment, the main purpose of the fire extinguishing grenade anti-drop unit 9 is as a protective device to prevent the fire extinguishing grenade from falling and detonating when the fire extinguishing grenade delivery unit 7 fails. The support plate 93 in the fire extinguishing grenade anti-drop assembly is the main structure for supporting the fire extinguishing grenade. Under normal conditions, it is set at a 90° angle to the back plate 10, and its normal position is very close to the fire extinguishing grenade 74. Because of the close distance between it and the fire extinguishing grenade 74 under normal conditions, even if the fire extinguishing grenade falls onto the support plate 93, it will not explode, ensuring the safety of the fire extinguishing grenade 74. The limiting recess on the top of the 93 plate can circumferentially limit the fire extinguishing bomb 74 to prevent it from rolling or moving when it falls. The working angle of the support plate 93 is adjusted by the power motor 91. The power motor 91 is equipped with a remote controller, which allows the staff to remotely control the working status of the power motor 91. When the fire extinguishing bomb 74 needs to be deployed, the power motor 91 drives the swing arm 92 and the support plate 93 to rotate. After rotation, the support plate 93 is set parallel to the back plate 10. At this time, the support plate 93 will not block the falling path of the fire extinguishing bomb 74, ensuring the smoothness of its deployment action.

[0059] A pressure switch is provided at the center of the bottom of the limiting recess in the tray 93. The pressure switch is connected to a buzzer, which can sound an alarm when the fire extinguishing bomb 74 falls onto the tray 93, alerting the staff that the fire extinguishing bomb 74 has fallen off the fire extinguishing bomb delivery unit 7 and needs to be reset before work can resume.

[0060] The fire extinguishing bomb anti-fall unit 9 is also equipped with a first swing limit contact 94 and a second swing limit contact 95. The first swing limit contact 94 and the second swing limit contact 95 constrain two key working positions of the power motor 91. The first swing limit contact 94 is fixed to the back side of the back plate 10 and is used to limit the swing arm 92 when it is in the vertical downward position. The second swing limit contact 95 is fixed to the upper part of the power motor 91 housing through a connecting plate and is used to limit the swing arm 92 when it is in the horizontal position.

[0061] Specific implementation method three: Combining Figures 1 to 10This embodiment differs from specific embodiment one in that the main body of the inspection robot also includes a fire extinguishing grenade auxiliary delivery unit 8. The fire extinguishing grenade auxiliary delivery unit 8 includes an electric push rod 82, which is fixed to the side wall of the guide slider 54 via a push rod mounting base 81. A flexible metal wire 83 is fixed to the telescopic end of the electric push rod 82, and the bottom of the flexible metal wire 83 has a hook 84 for engaging with the safety pull ring on the fire extinguishing grenade 74. Other components and connection methods are the same as in specific embodiment one.

[0062] In this embodiment, the purpose of the electric actuator 82 is to serve the active-action fire extinguishing bomb. When using this type of fire extinguishing bomb, the safety ring on the bomb body needs to be pulled first. After a certain period of time (approximately 6 seconds), it will explode. After the explosion, the extinguishing dry powder released inside will rapidly spread to the surrounding environment with the impact force of the explosion. Its effective fire extinguishing range can reach 3-5 m³. The electric actuator 82 is equipped with a remote controller, allowing personnel to remotely control the working status of the electric actuator 82. The piston rod end of the electric actuator 82 is equipped with a flexible metal wire 83 and a hook 84. The hook 84 is attached to the safety ring in the active-action fire extinguishing bomb, and the tail end of the hook 84 is wrapped with the flexible metal wire 83. At the piston rod end of the electric push rod 82, the metal wire has high strength and its length is greater than the gap between the bottom of the fire extinguishing bomb 74 and the fire extinguishing bomb anti-drop support plate 93. This ensures that when the fire extinguishing bomb 74 falls onto the support plate 93 after the fire extinguishing bomb delivery unit 7 fails, the safety pull ring will not disengage, thus preventing the fire extinguishing bomb 74 from detonating. This ensures the safety of the fire extinguishing bomb 74 when it is not in operation. With the fire extinguishing bomb 74 fixed in place by the fire extinguishing bomb delivery unit 7, the electric push rod 82 drives the hook 84 to move upward, thereby pulling the safety pull ring. After the safety pull ring disengages from the fire extinguishing bomb 74, the fire extinguishing bomb delivery unit 7 can be controlled to deliver the fire extinguishing bomb 10 to the target area within the reaction time to achieve the purpose of suppressing the fire.

[0063] The present invention has been disclosed above with reference to preferred embodiments, but it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed structure and technical content to create equivalent embodiments without departing from the scope of the present invention. However, any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.

[0064] Working principle

[0065] In operation, this application first assembles the various components according to the connection relationships described in Specific Embodiments One to Three. This application has two working modes: inspection and deployment of fire extinguishing bombs.

[0066] Operating Condition 1: During the inspection, the rotating motor 3 drives the rotating disk 4 to rotate until the length of the transverse constraint guide rail 51 is in the same direction as the length of the power station. At this time, the moving trolley 52 moves along the length of the transverse constraint guide rail 51. With the moving trolley 52 driving the camera 64 to move, the inspection of multiple rows of electrical equipment from a high position can be achieved. If the travel of the transverse constraint guide rail 51 is too long, the wide angle of the camera 64 itself cannot completely cover all the electrical equipment in the front and rear rows. At this time, the rotating motor 3 can be driven to drive the rotating disk 4 to rotate slowly. With the rotation of the rotating disk 4 and the transverse movement of the moving trolley 52, the coupling of the two working actions can make the acquisition range of the camera 64 cover all the electrical equipment in the area, so as to achieve the comprehensiveness and accuracy of the inspection work.

[0067] Operating Condition 2: When the fire extinguishing bomb is being deployed, if the inspection robot discovers a potential fire hazard such as flames or smoke during its inspection work, the operator can control the rotating disk 4 and the moving trolley 52 to quickly move above the suspected fire point. At this time, the operator first controls the power motor 91 in the fire extinguishing bomb anti-fall unit 9 to rotate and drive the support plate 93 to be in a state parallel to the back plate 10. Then, the operator controls the fire extinguishing bomb auxiliary deployment unit 8 to work, and pulls off the safety ring on the fire extinguishing bomb 74 by retracting the electric push rod 82 in the opposite direction. Finally, the operator controls the electromagnet 72 in the fire extinguishing bomb deployment unit 7 to be de-energized and lose its magnetism. Under the action of losing the attraction force, the magnetic block 73 drives the fire extinguishing bomb 74 to fall freely, thus realizing the bomb deployment action.
