The invention belongs to the technical field of electromechanical monitoring, in particular to an efficient electromechanical monitoring device for expressway tunnel. The device comprises a camera, acentral controller and a fixed plate, the fixed plate is installed on the top face of the tunnel and extends in the longitudinal direction of the tunnel, an inverted-T-shaped sliding rail is welded tothe lower surface of the fixed plate, travelling wheels are connected to the two sides of the T-shaped sliding rail in a rolling mode, a U-shaped shell is arranged below the T-shaped sliding rail, adustproof cover is fixedly connected to the lower surface of the U-shaped shell, the camera is installed in the dustproof cover, a double-shaft motor is installed on the inner bottom face of the U-shaped shell, and worms are coaxially and fixedly connected to output shafts at the two ends of the double-shaft motor. The monitoring device can patrol back and forth in the tunnel, dead-corner-free monitoring in the tunnel can be achieved without arranging a plurality of monitoring devices, the cost is reduced, the monitoring efficiency is greatly improved, accident rescue and traffic organizationin the tunnel are facilitated, and safe and stable operation of the tunnel is facilitated.

The invention belongs to the field of environment monitoring, and particularly relates to a hydraulic ring geological environment monitoring equipment mounting structure which comprises a placement device, a protection device is arranged at the top of the placement device, the top of the placement device is fixedly connected with the bottom of the protection device, and a shielding device is arranged at the top of the protection device. The top of the protection device is fixedly connected with the bottom of the shielding device, gravity devices are uniformly arranged at the bottom of the placement device, the bottom of the placement device is fixedly connected with the tops of the gravity devices, a filter plate is arranged on the outer surface of the placement device, and the inner wall of the filter plate is fixedly connected with the outer surface of the placement device. The shielding device comprises a shielding plate, and a positioning ring is arranged at the bottom of the shielding plate, aiming at the defects in the prior art, the invention provides the equipment mounting structure for hydraulic environment geological environment monitoring, and the problems that a traditional mounting structure is poor in sealing performance and difficult to find during use are solved.

The invention discloses a 4K ultra-high-definition display spliced screen, which comprises a plurality of shells installed on a wall body and a display screen arranged in front of the shells, throughholes are formed in the centers of the surfaces of the shells, moving plates are arranged in the shells, and more than one spring is installed between the outer ring of each moving plate and the innerwall face of the corresponding shell. The shaft rods are installed at the positions, right opposite to the installation grooves, of the back faces of the display screens, bases are installed at one ends of the shaft rods, one ends of the bases are installed on the movable plate, and adjusting mechanisms for adjusting the distance between the display screens are arranged outside the display screens. The device is simple in structure, the distance between the display screens can be effectively adjusted through the adjusting mechanism, the display screens can be effectively separated during independent display, picture overlapping caused by excessive contact is avoided, the monitoring effect of each display screen is prevented from being affected, the display screens can completely abut against each other, and the display effect is improved, so that a plurality of display screens are spliced into a whole, and the display area is increased.

The invention discloses a monitoring device for urban domestic sewage discharge, which relates to the technical field of sewage discharge. The urban domestic sewage discharge monitoring device includes a fixed cylinder. A fixed ring is fixedly installed on the inner wall of the fixed cylinder near the left end. Mechanism, the inside of the fixed cylinder near the right end is fixed with a monitoring piece through a fixed column, the filter mechanism includes an elastic ring, an annular cavity, an elastic filter piece and a movable part, and the elastic ring is fixedly installed on the left side of the fixed ring , the outer surface of the elastic ring is in contact with the inner wall of the fixing cylinder. The urban domestic sewage discharge monitoring device is equipped with a filter mechanism and a deceleration mechanism to shake off the sundries on one side of the elastic filter, avoiding the accumulation of sundries affecting the sewage discharge efficiency, and slowing down the water flow speed outside the monitoring piece, so that the monitoring components work normally.

The invention discloses a monitoring device with a camera lens protection film capable of being automatically pasted and replaced and a film pasting method of the monitoring device. The monitoring device comprises a device body and a monitoring camera lens arranged at the bottom of the device body. First slide grooves are formed in the two sides of the monitoring camera lens correspondingly and located in the device body. The two first slide grooves are symmetrically formed. First slide rods are installed in the first slide grooves in a sliding manner. A film replacement head is arranged at the end, close to the opening of the corresponding first slide groove, of each first slide rod. First containing cavities are formed in the two sides of the device body correspondingly. First drive motors are arranged in the first containing cavities. Output shafts of the first drive motors are connected with fixing columns. The two fixing columns are located on the two sides of the device body correspondingly. Second slide grooves are formed in the fixing columns. By means of the monitoring device and the film pasting method, the camera lens protection film can be automatically pasted and replaced, the automation degree is high, it is avoided that monitoring pictures are fuzzy after long-time use and consequently the monitoring effect is influenced, the structure is simple, use is convenient, and cost is low.
