On-site monitoring device for bidding and tendering

Abstract

The invention provides an on-site monitoring device for bidding and tendering, and relates to the technical field of monitoring devices. A supporting plate is fixedly connected to the middle of the front end face of the L-shaped fixing plate, and a reciprocating driving piece is arranged on the upper portion of the L-shaped fixing plate. A reciprocating motion part is arranged on the upper end face of the supporting plate, and a monitoring camera body is installed on the upper portion of the reciprocating motion part. Through the cooperation of the reciprocating driving part and the reciprocating moving part, the visual blind area of the monitoring camera main body can be reduced, and the monitoring effect of the monitoring device is improved; and through cooperation of a water absorption mechanism, a cooling pipe fitting, a driving disc and a fixed rack, the interior of the monitoring camera main body is effectively cooled without power loss, so that the energy-saving performance is improved, and the problems that an existing monitoring device is installed at a fixed position, so that a visual blind area exists, and the monitoring effect is poor are solved. And a heat dissipation fan in an existing monitoring device needs to consume a power supply, so that the energy-saving performance is reduced.

Description

technical field [0001] The invention relates to the technical field of monitoring devices, in particular to a monitoring device for bidding on-site. Background technique [0002] Bidding is a form of comprehensive economic responsibility system that promotes competition in the field of capital construction. At the bidding site, in order to ensure the fairness of the bidding environment, real-time monitoring is generally carried out through monitoring devices. [0003] However, when the existing monitoring device is in use, it is usually installed in a fixed position on the bidding site, so that the monitoring device has some blind spots, thus reducing the monitoring effect of the monitoring device, and although the internal A cooling fan is installed, and the inside of the surveillance camera is cooled by the fan, but the cooling fan needs to lose power when cooling down, thus reducing the energy saving of the surveillance camera. SUMMARY OF THE INVENTION [0004] In view...

Problems solved by technology

[0003] However, when the existing monitoring device is in use, it is usually installed in a fixed position on the bidding site, so that there are some blind spots in the monitoring device, thereby reducing the monitoring effect of the monitoring device, and although the existing monitoring device inside A cooling fan is installed to cool down the inside of the surveillance camera by distributing the fan, but the cooling fan needs to lose power when cooling down, thus reducing the energy saving performance of the surveillance camera
