Problems solved by technology

"In the actual testing process, although impurities cannot enter the pipe body through the filter screen, due to the suction effect of the fan, the impurities will adhere to the outer wall of the filter screen, resulting in a greatly reduced ventilation volume in the pipe body, which greatly reduces the air flow rate of the fan. Air volume detection accuracy

Embodiment 1

[0022] refer to Figure 1-2 , a highway mechanical and electrical equipment detection device, comprising a tube body 1, the inner wall of the tube body 1 is provided with a fan embedded groove 2, a detection tube 5 is arranged in the tube body 1, and a digital micromanometer 6 is installed on the detection tube 5, It should be noted that the connection and installation methods of the detection tube 5 and the digital micromanometer 6 are the same as those of the existing fan air volume detection device. Since they have nothing to do with the design purpose of this solution, they will not be described in detail.

[0023] A dust filter 3 is installed at the air inlet of the pipe body 1, and a strip groove 31 is provided on the side wall of the dust filter 3, and a vibrating spring 4 is embedded in the strip groove 31, and both ends of the vibrating spring 4 are connected to the strip groove. The two inner walls of 31 are fixedly connected, and the side wall of the pipe body 1 is ...

Embodiment 2

[0030] refer to Figure 3-5 , different from Embodiment 1, the sleeve 10 is rotatably connected in the storage tank 9 through a damping shaft, a plurality of dust storage tanks 101 are provided at equal intervals on the circumferential side wall of the sleeve 10, and the inner bottom of the storage tank 9 is installed with Grounding post 14.

[0031] It should be noted that the sleeve 10 is rotationally connected in the storage slot 9 through a damping shaft, so that the sleeve 10 will not rotate when there is no external force or the external force is small. When the block 12 moves back and forth, the sleeve 10 will not be rotated to cause insufficient static electricity to absorb impurities. Can be gathered into a group, and the whole body is subjected to a stronger gravity effect, and will not reattach to the outer wall of the dust filter net 3 as the airflow rises.

[0032] Further, since the generated static electricity is always gathered above the sleeve 10, and the sl...

Abstract

The invention discloses a detection device for expressway electromechanical equipment. The detection device comprises a pipe body; a fan embedment groove is formed in the inner wall of the pipe body;a detection pipe is arranged in the pipe body, and a digital micromanometer is installed on the detection pipe; a dust filter screen is installed at an air inlet of the pipe body, a strip-shaped groove is formed in the side wall of the dust filter screen, vibrating reeds are embedded in the strip-shaped groove, and two ends of the vibrating reeds are fixedly connected with two inner walls of the strip-shaped groove; a containing groove is formed in the side wall of the pipe body, a sleeve is arranged in the containing groove, a power generation sheet is embedded in the sleeve, and the power generation sheet is made of a piezoceramic material and electrically connected with the vibrating reeds through a capacitor; and an arc-shaped groove is formed in the inner wall of the pipe body. According to the detection device, by making the vibrating reeds vibrate constantly and making the dust filter screen shake constantly, impurities adhering to the dust filter screen can be rapidly shaken off, good permeability of the dust filter screen is guaranteed, and the detection precision of the digital micromanometer for the air volume in the pipe body is greatly improved.

Description

technical field [0001] The invention relates to the related technical field of electromechanical equipment detection devices, in particular to a highway electromechanical equipment detection device. Background technique [0002] There are often a large number of electromechanical equipment on the expressway, including monitoring equipment, toll system related equipment and communication equipment. For road tunnels, ventilation equipment will also be provided. [0003] Before the electromechanical equipment on the road is put into use, it needs to pass the detection device. Wherein, the application number is that CN209557314U has proposed " a kind of expressway electromechanical equipment detection device ". In this scheme, in order to ensure the detection effect, "a filter screen is installed at the air inlet at the left end of the pipe body to filter out the impurities entering the air inlet." In the actual detection process, although impurities cannot enter the pipe body...
