Description

Technical Field

[0001] The present invention relates to the technical field of building measurement, and in particular to a construction engineering actual measurement and quantity management system based on BIM technology. Background Art

[0002] BIM technology is a digital tool used in engineering design, construction, and management. By integrating the digital and information models of buildings, it is shared and transmitted throughout the entire life cycle of project planning, operation, and maintenance, enabling engineering and technical personnel to correctly understand and efficiently respond to various building information, providing a basis for collaborative work for the design team and all construction entities including construction and operation units, and playing an important role in improving production efficiency, saving costs, and shortening construction periods. The core of BIM is to establish a virtual three-dimensional model of the building project and use digital technology to provide this model with a complete and actual building project information database. This database not only contains geometric information, professional attributes, and status information describing the building components, but also contains status information of non-component objects, such as space and motion behavior. With the help of this three-dimensional model containing building project information, the degree of information integration of the building project is greatly improved, thereby providing a platform for engineering information exchange and sharing for the relevant stakeholders of the building project. In BIM technology, various relevant information data of the building project are collected by various information collection and surveying devices.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] (1) The construction engineering actual measurement and quantity management system based on BIM technology automatically cleans the lens of the telescopic observation mirror by setting a cleaning device to avoid manual wiping of the lens and scratching the lens due to operational errors, thereby affecting the accuracy of measurement. During cleaning, water first enters the water tank through the water pipe, and then enters the cleaning pipe through the spoiler ring. The water tank is blown into the water tank by setting a connection between the air pump and the air pipe to make the water agitated in the water tank to avoid the water entering the water tank directly flowing out from the bottom and being unable to clean the lens inside the cleaning pipe. When the lens is cleaned, the air pump is used to blow air into the water tank to dry the residual moisture on the lens and the water in the water tank and the cleaning pipe to make it flow out from the leaking pipe. After cleaning the residual moisture inside, the spoiler ring is set to rotate the water entering the water tank to disrupt the original flow direction of the water flow, so that the water rolls in the water tank and the cleaning pipe, thereby achieving the cleaning effect on the lens.

[0015] (2) The construction engineering actual measurement and quantity management system based on BIM technology provides a rotational force to the spoiler ring by setting a motor and a transmission gear, fixes the position and configuration of the spoiler ring by setting a rotating drum, drives the rotating drum to rotate by setting a gear tooth and a transmission gear, disturbs the water inside the water tank by setting an outer wave plate, disturbs the water entering the cleaning pipe through the water spray hole by setting an inner wave plate, allows the water inside the water tank to enter the cleaning pipe by setting a water permeable hole, allows the water after cleaning the lens to flow to the outside of the lower part of the box through the water leakage pipe, and blocks the split rubber sheet when the air pump is not turned on, thereby preventing water from flowing back into the air pump through the air pipe and damaging the air pump.

[0016] (3) The construction engineering actual measurement and quantity management system based on BIM technology supports the air pump by setting a storage plate, stores clean water by setting a water tank device, so that the cleaning device can be used to clean the lens at any time during measurement, adds water to the inside of the water tank by setting a water tank port, and prevents dust from entering the inside of the water tank, blocks the water inlet by setting a plugging plate, and controls the closing of the plugging plate by setting a pull rod and a handle. When in use, hold the handle and lift it up, and transmit the upward lifting force to the plugging plate through the pull rod, pull the plugging plate upward to make the plugging plate leave the water inlet, and finally the water flows into the water tank to clean the lens.

[0017] (4) The construction engineering actual measurement and quantity management system based on BIM technology adjusts the observation box by setting an adjustment device to achieve the measurement height, and isolates the internal structure of the adjustment device by setting a shell to prevent workers from being injured due to accidental touch. The internal structure is fixed by setting a bottom plate. When in use, start the second motor to drive the second transmission gear to rotate, and drive the shaft column to rotate through the gear plate, so that the shaft column and the threaded hole rotate on the outer surface of the threaded rod, so that the threaded rod drives the observation box to rotate, thereby adjusting the height of the observation box, avoiding the unstable contact between the fixed frame and the ground due to repeated movement of the connection between the fixed frame and the ground, and fixing the position of the observation box by setting a support rod. By setting a fixed plate, I increase the contact with the ground, and by setting a telescopic observation mirror, the lens can be telescoped into the cleaning tube, which is convenient for cleaning and protecting the lens.
