This utility model provides an adjustable base for a billboard column, belonging to the field of billboard technology. It includes an advertising mechanism comprising a base for support, a column fixedly installed on top of the base, and a billboard fixedly installed on top of the column; and a wind-resistant mechanism including a counterweight component for balancing the base and a friction component for increasing friction at the bottom of the base. The counterweight component includes several mounting grooves formed on the top of the base and counterweight blocks disposed within the mounting grooves for balancing the base. Several indicator cards are provided on the top of the base to indicate the placement position of the counterweight blocks. This utility model, through the cooperation between the counterweight component and the friction component, increases the counterweight and bottom friction of the base, solving the problem of insufficient wind resistance caused by fixed counterweights in traditional bases. It prevents instability of the billboard in windy weather, improves its wind resistance, and ensures the billboard remains stable and reliable during use.

The utility model provides a water conservancy project pipe -in -place wire -laying device relates to pipe -in -place wire -laying technical field, the utility model discloses a measurement casing, one side outer wall of measurement casing is fixedly connected with the swivel plate along the horizontal direction, the output of swivel plate is fixedly connected with the tape roll along the horizontal axis direction, the outer circumferential surface of tape roll is wound with the measurement scale band, one end of measurement scale band is fixedly connected with the end of tape roll. The utility model discloses, through setting up detachable main counter weight and vice counter weight, the flexible adjustment of counter weight is realized with cooperation connecting device. When outdoor wind power is bigger, can install vice counter weight through the cooperation of rectangular connecting block and rectangular slot fast, utilize the clamping structure of wedge -shaped clamping block and clamping groove to ensure that the connection is stable, significantly increase the overall counter weight, effectively offset the impact of wind power to the scale band, avoid the scale band to shake, ensure that the measurement scale band always keeps vertical straight state in the wire -laying process, improve the accuracy of pipe -in -place path measurement.

The utility model discloses a water conservancy monitoring equipment for water conservancy engineering relates to water conservancy engineering technical field, including monitoring box, the monitoring box bottom fixedly connected with the buoy, the buoy inside fixedly connected with the baffle, the baffle divides the buoy and is distributed with the high pressure gas cavity and the counterweight chamber of high and low, the baffle top fixedly connected with the multisection electric push rod, multisection electric push rod piston rod end fixedly connected with the push board, through installing the buoy on the monitoring box bottom, when needing equipment to sink to the water bottom, just can be in the water suction into the counterweight chamber when lowering equipment buoyancy also increase counterweight, make it can sink to the water bottom quickly, when needing to float the salvage equipment, just need to discharge the water in the counterweight chamber, and the high pressure air in the high pressure gas cavity is introduced into the counterweight chamber inside and annular airbag inside can make the equipment whole buoyancy increase quickly, and then make the equipment can float quickly and be convenient for salvage, overall use is very convenient.

The utility model provides an overhead line anti-dancing counterweight device relates to anti -dancing counterweight device technical field. Including three mounting blocks and cable, every two mounting blocks are provided with adjusting buffer structure, adjusting buffer structure includes the wire slot, the wire slot opens in the one side of mounting block, the inside of wire slot is provided with rubber ring frame, through setting adjusting buffer structure, under the action of screw rod and screw hole cylinder, can adjust the distance between two sides mounting block and the mounting block of middle position, and then can adjust installation according to actual cable distance between, and there is sliding cylinder and fixed link etc. component connection between two adjacent cables, will not collide and entangle in the process of dancing, and can under the action of sliding cylinder and fixed link, cooperation buffer spring makes, when the mounting block of two sides can drive buffer spring stretching and extrusion, and then can buffer.
