Specific embodiments

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] As Figure 1 and Figure 2 shown, the present utility model provides a technical solution for a remote off-site bid evaluation audio and video supervision terminal, including a processor housing 2, a remote communication module 1 is fixedly installed at the upper end of the processor housing 2, a microphone 3 and a camera module 4 are provided below the processor housing 2, a bracket assembly 5 is provided below the processor housing 2, a positioning mechanism 6 is provided at the lower end of the positioning pillar 501. During the bid evaluation process, the microphone 3 and the camera module 4 can record the bid evaluation site. After being processed by the processor in the processor housing 2, the on-site information of the bid evaluation can be transmitted to off-site personnel through the remote communication module 1 to achieve remote off-site bid evaluation.

[0022] As Figure 2 and Figure 3 shown, the bracket assembly 5 includes a positioning pillar 501 provided below the processor housing 2, a positioning base 507 is fixedly installed at the bottom of the positioning pillar 501, a telescopic pillar 505 is fixedly installed on the positioning pillar 501, an installation notch 504 is opened at the upper end edge of the telescopic pillar 505, a storage housing 502 is fixedly installed at the upper end of the positioning pillar 501, a sealing end cover 503 is movably installed at the upper end of the storage housing 502, movable chutes 506 are opened on both sides of the positioning pillar 501, and the lifting cross beam 601 extends out of the positioning pillar 501 through the movable chutes 506.

[0023] Specifically, after rotating the telescopic support 505, the camera module 4 can be driven to move up and down, thereby adjusting the shooting height of the camera module 4, and the microphone 3 and the camera module 4 can be retracted into the storage shell 502. After the microphone 3 and the camera module 4 are retracted into the storage shell 502, the sealing end cover 503 can be covered to prevent the microphone 3 and the camera module 4 from being damaged.

[0024] like Figure 2 and Figure 4 As shown, the positioning mechanism 6 includes a positioning suction cup 607 fixedly mounted on the bottom of the positioning base 507, a vacuum cylinder 605 fixedly mounted in the positioning pillar 501, a piston 604 movably mounted in the vacuum cylinder 605, a driving connecting rod 603 fixedly mounted on the piston 604, a lifting beam 601 fixedly mounted on the upper end of the driving connecting rod 603, a threaded ring 602 mounted on the positioning pillar 501, and a connecting pipe 606 is provided between the vacuum cylinder 605 and the positioning suction cup 607.

[0025] Specifically, after the threaded ring 602 is rotated upward, it will drive the lifting beam 601 to move upward. After the lifting beam 601 moves upward, it will drive the driving connecting rod 603 to move upward, thereby driving the piston 604 to move upward. When the piston 604 moves upward, it will suck the air in the positioning suction cup 607 into the suction cylinder 605, so that the positioning suction cup 607 is firmly adsorbed on the floor, so that the entire device remains stable on the floor, preventing the device from being knocked over and reducing the risk of the device being damaged.

[0026] Working principle: When in use, the sealing end cover 503 can be opened, and after opening the sealing end cover 503, the telescopic support 505 can be rotated. After rotating the telescopic support 505, the camera module 4 can be driven to move up and down, thereby adjusting the shooting height of the camera module 4. After the shooting height of the camera module 4 is adjusted, the positioning base 507 can be pressed on the floor. After the positioning base 507 is pressed on the floor, the threaded ring 602 can be rotated upward. After rotating the threaded ring 602 upward, it will drive the lifting beam 601 to move upward. After the lifting beam 601 moves upward, it will drive the driving connecting rod 603 to move upward. After the driving connecting rod 603 moves upward, it will drive the piston 604 to move upward. When the piston 604 moves upward, it will suck the air in the positioning suction cup 607 into the suction cylinder 605. When the air in the positioning suction cup 607 is sucked into the suction cylinder 605, it will be firmly adsorbed on the floor, so that the entire device remains stable on the floor. To reduce the risk of equipment damage, the microphone 3 and the camera module 4 can record the bid evaluation site during the bid evaluation process. After being processed by the processor in the processor housing 2, the on-site information of the bid evaluation can be transmitted to remote personnel through the remote communication module 1 to realize remote and off-site bid evaluation. After the bid evaluation is completed, the telescopic support 505 can be rotated in the opposite direction to retract the microphone 3 and the camera module 4 into the storage housing 502. After the microphone 3 and the camera module 4 are retracted into the storage housing 502, the sealing end cover 503 can be covered to prevent the microphone 3 and the camera module 4 from being damaged. The user can turn the threaded ring 602 downward. After turning the threaded ring 602 downward, the lifting beam 601 will lose its obstruction. After the lifting beam 601 loses its obstruction, the lifting beam 601 can be pressed down to make the piston 604 move downward, squeezing the air in the vacuum cylinder 605 into the positioning suction cup 607, so that the positioning suction cup 607 is off the floor, making it easier for the user to remove the entire device.
