Description
Technical Field
[0001] The present invention relates to the technical field of seepage heat transfer in fractured rock masses, and particularly to a seepage heat transfer device and system for fractured rock masses. Background Art
[0002] Due to the extremely complex in-situ environmental conditions of engineering rock masses, it is very difficult to reveal the hydrothermal migration law of fractured rock masses at the engineering scale. Therefore, indoor experimental research on the hydrothermal migration of fractured rock masses plays an irreplaceable role in revealing the seepage and heat transfer laws of rock mass fractures, mastering the hydrothermal migration mechanism of fractured rock masses under the action of fluid-solid coupling, and understanding the influencing factors of seepage heat transfer in fractured rock masses under high temperature and high pressure. On this basis, scholars at home and abroad have developed a large number of experimental devices for hydrothermal migration of fractured rock masses. In order to restore the hydrothermal migration situation in deep rock mass fractures, high-pressure, high-temperature, and high-water-pressure experimental conditions need to be provided during the experiment. Most of the existing experimental devices are realized by transforming the pressure chamber of a triaxial testing machine, and the rock samples used are mostly cylindrical. In this case, in order to provide uniform and constant temperature and axial pressure to the samples, the rock samples need to be in a completely enclosed state throughout the experiment. The existing experimental devices have the following problems: poor water sealing performance, and there is generally a water leakage problem during the experiment, resulting in inaccurate measurement of the inlet and outlet water temperature and flow rate, which affects the experimental accuracy.
[0003] A seepage heat transfer device and system for fractured rock masses with the publication number CN114184533A includes a support mechanism, a first water sealing mechanism, a second water sealing mechanism, a water inlet mechanism, a water outlet mechanism, and a heating mechanism. The first water sealing mechanism includes a top plate and a movable plate oppositely arranged along a first direction and a first driving component for driving the movable plate to move along the first direction. The second water sealing mechanism includes two pressing plates oppositely arranged along a second direction and a second driving component for driving the two pressing plates to move towards or away from each other. The water inlet mechanism includes a first sealing baffle, a water inlet groove provided on the first sealing baffle, and a water inlet pipe communicated with the water inlet groove; the water outlet mechanism includes a second sealing baffle, a water outlet groove provided on the first sealing baffle, and a water outlet pipe communicated with the water outlet groove. This experimental device improves the water sealing effect, effectively avoids the problem of water leakage during the experiment, thereby obtaining accurate inlet and outlet water temperature and flow rate data, and improving the experimental accuracy.
[0004] In the above technical solution, the fractured rock sample cannot be clamped and sealed quickly, and at the same time, the pressure cannot be controlled as needed, which is not convenient for studying the seepage heat transfer of fractured rock masses in different situations, so improvement is needed.
