DETAILED DESCRIPTION

[0023] In order to further explain the technical solution of the present utility model, it is described in detail through specific embodiments below.

[0024] See also Figure 1The utility model provides a large-scale photovoltaic power station intelligent inspection vehicle, including a track 1, an inspection vehicle body 2, a monitoring camera 3 and a temporary charging device 4. The inspection vehicle body 2 is installed on the upper part of the track 1, and the inspection vehicle body 2 can move along the track 1. A monitoring camera 3 is arranged above the inspection vehicle body 2, and a temporary charging device 4 is arranged on the track 1.

[0025] See also Figure 2-3 In the utility model, the temporary charging device 4 includes a protective frame 41, a first charging seat 42, a power cord 43, a second charging seat 44 and a retractable protection mechanism 45. The protective frame 41 is sleeved on the outside of the track 1, and the bottom of the protective frame 41 is bolted to the track 1. The first charging seat 42 is installed on the side of the protective frame 41, and the bottom of the first charging seat 42 is connected to the power cord 43. The second charging seat 44 is installed on the side of the inspection vehicle body 2, wherein the first charging seat 42 and the second charging seat 44 are at the same height, and the first charging seat 42 can transmit power to the second charging seat 44. The retractable protection mechanism 45 is provided on the protective frame 41 and the inspection vehicle body 2.

[0026] To further explain, when the first charging seat 42 establishes an electrical connection with the second charging seat 44 , the inspection vehicle body 2 will be completely parked inside the protection frame 41 , allowing the protection frame 41 to provide good shielding and protection for the inspection vehicle body 2 .

[0027] To further explain, the first charging seat 42 and the second charging seat 44 use wireless charging technology to transmit power. The wireless charging technology transmits energy through a magnetic field, so that the first charging seat 42 and the second charging seat 44 will not have actual contact, and there is no need for a plug and a socket to dock. The charging operation is simpler and smarter, and will not hinder the passage of the inspection vehicle body 2. In addition, since wireless charging is achieved through magnetic resonance, there are no exposed contacts and it has excellent waterproof performance to adapt to the outdoor working environment of the inspection vehicle body 2.

[0028] See also Figure 4-6The retraction protection mechanism 45 of the utility model includes a telescopic sleeve 451, a reset spring 452, a video line 453, a guide wheel 454, a guide frame 455 and a guide slope 456. The telescopic sleeve 451 is screwed on the top surface of the inspection vehicle body 2. The top telescopic end of the telescopic sleeve 451 is screwed to the monitoring camera 3. The monitoring camera 3 is connected to the inspection vehicle body 2 through the telescopic sleeve 451. A reset spring 452 is arranged between the internal pipe sections of the telescopic sleeve 451. The reset spring 452 supports the weight of the monitoring camera 3 to keep the telescopic sleeve 451 in the extended state. The bottom of the monitoring camera 3 is connected to the monitoring camera 3. A video line 453 is connected, and the video line 453 passes through the hollow telescopic tube sleeve 451 to connect with the inspection vehicle body 2, so as to establish a data connection between the monitoring camera 3 and the inspection vehicle body 2. Guide wheels 454 are installed on both sides of the telescopic end of the top of the telescopic tube sleeve 451, and guide frames 455 are screwed on the left and right side walls inside the protective frame 41. The guide wheel 454 can slide along the bottom of the guide frame 455. A guide slope 456 is set at the end of the guide frame 455. The guide frame 455 controls the lifting and lowering of the guide wheel 454 through the guide slope 456, thereby controlling the lifting and retracting action of the telescopic tube sleeve 451.

[0029] To further explain, two sections of guide slopes 456 are provided on the guide frame 455 , and the two sections of guide slopes 456 are symmetrically arranged at the front and rear sections of the guide frame 455 , allowing the inspection vehicle body 2 to travel back and forth.

[0030] It is further explained that the inclination angle of the guide slope 456 is not greater than 30 degrees, so as to slow down the telescopic movement speed of the telescopic tube sleeve 451 and avoid damaging the monitoring camera 3 thereon.

[0031] To further explain, the video cable 453 adopts a spring cable, so that the video cable 453 has good elasticity and can better adapt to the telescopic action of the telescopic tube sleeve 451.

[0032] Here’s how it works:

[0033] First, before use, first connect the power cord 43 to an external power source to power on the temporary charging device 4 .

[0034] Second, when in use, the inspection vehicle body 2 can move along the track 1 autonomously or by remote control to conduct inspections around the photovoltaic power station. During the inspection, the monitoring camera 3 transmits image information to the inspection vehicle body 2 via the video line 453, which is then transmitted back to the monitoring room by the inspection vehicle body 2, helping staff to promptly discover equipment failures, defects and other equipment abnormalities, thereby improving the efficiency of operation and maintenance of the photovoltaic power station.

[0035] Third, during use, since the photovoltaic power station occupies a large area and the inspection cycle is long, the inspection vehicle body 2 is prone to return due to insufficient power during the inspection work, resulting in the failure to complete the inspection task smoothly. By setting a temporary charging device 4 on the track 1, when the inspection vehicle body 2 is low in power, it can be docked in the nearby protective frame 41, allowing the first charging seat 42 and the second charging seat 44 to establish an electrical connection to charge the inspection vehicle body 2 to meet the endurance requirements of the inspection vehicle body 2, and the first charging seat 42 and the second charging seat 44 use wireless charging technology to transmit power, so that the first charging seat 42 and the second charging seat 44 will not have actual contact, and will not hinder the passage of the inspection vehicle body 2. In addition, since wireless charging is achieved through magnetic resonance, there are no exposed contacts and it has excellent waterproof performance to adapt to the outdoor working environment of the inspection vehicle body 2.

[0036] Fourth, when the inspection vehicle body 2 enters the protective frame 41, the guide wheel 454 on the telescopic tube sleeve 451 will first dock with the guide frame 455. At this time, the guide wheel 454 moves along the bottom of the guide frame 455. When the guide wheel 454 moves down through the guide slope 456, it will drive the telescopic tube sleeve 451 to retract downward, thereby lowering the height of the monitoring camera 3 to ensure that the monitoring camera 3 and the inspection vehicle body 2 can smoothly enter the protective frame 41. During the charging process, the protective frame 41 can provide shielding protection for the inspection vehicle body 2 and the monitoring camera 3.

[0037] Fifth, when the inspection vehicle body 2 leaves the protection frame 41, when the guide wheel 454 moves upward through the guide slope 456, the telescopic sleeve 451 will stretch and reset under the elastic force of the reset spring 452, so that the monitoring camera 3 returns to its original height to obtain a better field of view.

[0038] The utility model provides an intelligent inspection vehicle for a large photovoltaic power station. A temporary charging device 4 is arranged on a track 1. When the inspection vehicle body 2 is in low power, it can be parked in a nearby protective frame 41, so that the first charging seat 42 and the second charging seat 44 establish an electrical connection to charge the inspection vehicle body 2 to meet the endurance requirement of the inspection vehicle body 2. The first charging seat 42 and the second charging seat 44 use wireless charging technology to transmit power, and have excellent waterproof performance to adapt to the outdoor working environment of the inspection vehicle body 2. A retractable protection mechanism 45 is arranged on the protective frame 41 and the inspection vehicle body 2. When the inspection vehicle body 2 enters the protective frame 41, when the guide wheel 454 moves downward through the guide slope 456, the telescopic sleeve 451 will be driven to retract downward, so that the height of the monitoring camera 3 is reduced, so as to ensure that the monitoring camera 3 and the inspection vehicle body 2 can smoothly enter the protective frame 41. During the charging process, the protective frame 41 can provide shielding protection for the inspection vehicle body 2 and the monitoring camera 3.
