This invention discloses a method for dynamically detecting the morphology of a cavity based on interlayer fracture vibrations, belonging to the field of cavity construction and monitoring technology for salt cavern gas storage. The method involves drilling and trenching to locate the cavity center and mudstone interlayer, deploying monitoring points and burying distributed monitoring optical fibers in the outer region of the cavity wall to capture the vibration wave signals of the interlayer fracture, recording the time difference and fluctuation intensity differences; analyzing the signal data of the propagation path to establish a three-dimensional coordinate system; and establishing a system of equations based on the time difference between the primary fracture vibration and the secondary vibration from the rock impact to calculate the three-dimensional coordinates of the fracture point and characteristic points of the cavity wall; then reconstructing the real-time contour of the cavity based on the layered symmetrical fracture characteristics and signal energy characteristics, and verifying it with other signals from the fracture layer and correcting the accuracy of the monitoring equipment. This method does not require interruption of the cavity construction operation, has high spatiotemporal resolution, and can accurately invert the cavity morphology, providing a basis for dynamic adjustment of the flow velocity and direction in water-soluble cavity construction, effectively reducing the risk of cavity collapse and excessive lateral dissolution.

This utility model provides a C-type power battery housing for dump trucks, belonging to the field of dump truck battery technology. It includes a housing body, two discharge terminals, and two connecting pipes. The housing body has a receiving cavity, a cooling channel, and an installation spacing. The discharge terminals are fixedly installed at the ends of the housing body, corresponding to the installation spacing. One end of the discharge terminal is located inside the receiving cavity, and the other end is located outside the housing body. The two discharge terminals are used to input positive and negative currents to the battery assembly, respectively. The connecting pipes are installed at the ends of the housing body. Both connecting pipes are connected to the cooling channel and are used for the inflow and outflow of a low-temperature medium into and from the cooling channel. The C-type power battery housing for dump trucks provided by this utility model results in a neat and orderly wiring arrangement within the housing body and convenient charging operation of the battery assembly; it also improves the heat dissipation performance of the C-type housing.
