[0001] The invention relates to the technical field of detection devices, in particular to a concrete quality detection device for water conservancy and hydropower engineering. Background Art

[0002] In water conservancy and hydropower projects, concrete is the main building material, and its quality is directly related to the safety, stability and durability of the project. Therefore, quality testing of concrete is a key link in ensuring the quality of the project. Among them, the compressive strength of concrete is one of the important indicators to measure its quality. It reflects the bearing capacity of concrete under compression. The concrete compressive strength testing device for water conservancy and hydropower projects is a device specially used to test the compressive strength of concrete. The device usually includes a machine, on which a fixture for placing concrete test blocks, a pressure applying mechanism and a data acquisition system are installed. During the test, the concrete test block is placed in the fixture, and a gradually increasing pressure is applied to the test block through the pressure applying mechanism until the test block is destroyed. The data acquisition system is responsible for recording the pressure changes during the entire process, thereby calculating the compressive strength of the concrete.

[0003] There are some problems with traditional concrete compressive strength testing devices. First, since the testing mechanism is usually installed on a machine platform, the overall size of the entire device is relatively large. This not only increases the manufacturing cost of the device, but also makes the device inconvenient during transportation, installation and use. Especially at the construction site of water conservancy and hydropower projects, where space is limited and the environment is complex, it is difficult to store large testing devices.
