DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] The embodiment of this application discloses a thermal response test vehicle with double heat exchange conduits. By rotating the bidirectional lead screw 41, the two mounting plates 50 are driven to move towards each other, so that the distance between the underground heat exchange assemblies 70 on the two mounting plates 50 is changed, which is convenient for penetrating into test holes of different sizes for testing, and can also prevent the mutual influence between the underground heat exchange assemblies 70 and improve the accuracy of the test.

[0017] To better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings of the specification and specific implementation manners.

[0018] Please refer to Figure 1 and Figure 2 , this embodiment provides a thermal response test vehicle with double heat exchange conduits, including a base 10. A thermal response tester 20 is fixedly arranged on the top of the base 10. Rollers are arranged at the four corners of the bottom of the thermal response tester 20. A fixing seat 30 is fixedly arranged on the front of the thermal response tester 20. Installation plates 50 are movably connected to both sides of the front of the fixing seat 30. A groove 60 is formed in the middle of the front of the fixing seat 30. An adjusting assembly 40 for driving the two installation plates 50 to move is arranged inside the groove 60. The adjusting assembly 40 includes a bidirectional lead screw 41, a driving motor 42, and movable blocks 43. The bidirectional lead screw 41 is rotatably connected inside the groove 60. The driving motor 42 is fixedly installed inside the fixing seat 30, and the output shaft of the driving motor 42 is fixedly connected to the bidirectional lead screw 41. The two movable blocks 43 are respectively sleeved and threadedly connected to both ends of the outside of the bidirectional lead screw 41, and the two movable blocks 43 are respectively fixedly connected to the two installation plates 50. The two movable blocks 43 are slidably connected inside the groove 60. By rotating the bidirectional lead screw 41 to drive the movable blocks 43 threadedly connected thereto to slide inside the groove 60, the two installation plates 50 move towards each other, changing the distance between the underground heat exchange assemblies 70 on the front of the installation plates 50, so that the two underground heat exchange assemblies 70 can smoothly extend into test holes of different sizes for thermal response tests. When the size of the test hole is sufficient, the distance between the two underground heat exchange assemblies 70 can also be increased, thereby reducing the mutual influence between the two underground heat exchange assemblies 70 and preventing phenomena such as thermal short circuit.

[0019] Please refer to Figure 1 , Figure 2 and Figure 3, the two underground heat exchange components 70 include mounting seats 71, liquid inlet pipes 72, U-shaped pipes 73, liquid outlet pipes 74, connecting pipes 75, valves 76, and hoses 77. The two mounting seats 71 are respectively arranged at the top and bottom of the front surface of the mounting plate 50. The liquid inlet pipe 72 is installed at one end of one of the mounting seats 71. The U-shaped pipe 73 is arranged at the bottom end of the liquid inlet pipe 72. The liquid outlet pipe 74 is fixedly arranged at the other end of the U-shaped pipe 73, and one end of the liquid outlet pipe 74 is installed on the other mounting seat 71. The two hoses 77 are respectively arranged at the top and bottom of the back surface of the mounting plate 50, and the two mounting seats 71 are communicated with the thermal response tester 20 through the two hoses 77. The hoses 77 are telescopic. The connecting pipe 75 is arranged between the liquid inlet pipe 72 and the liquid outlet pipe 74. The two valves 76 are respectively arranged at both ends of the U-shaped pipe 73. A storage box 80 is fixedly arranged on the back surface of the thermal response tester 20. A partition 90 is fixedly arranged in the middle of the storage box 80. Through the arrangement of the hoses 77, when the position of the mounting plate 50 changes, the two mounting seats 71 can always be communicated with the thermal response tester 20. Through the connecting pipe 75 arranged between the liquid inlet pipe 72 and the liquid outlet pipe 74 and the two valves 76 arranged at both ends of the U-shaped pipe 73, when the valves 76 are closed, the liquid inlet pipe 72 and the liquid outlet pipe 74 can be communicated through the connecting pipe 75, changing the heat exchange height and facilitating the test of rock and soil bodies at different heights. The storage box 80 is separated by the partition 90, so that the two underground heat exchange components 70 can be removed and placed on both sides inside the storage box 80 respectively, facilitating the carrying of the two underground heat exchange components 70.

[0020] The functional principle of the present application can be elaborated through the following operation modes:

[0021] In use, the base 10 is pushed to a suitable position beside the test hole, and then the underground heat exchange assembly 70 separated by the partition 90 inside the storage box 80 is taken out. The liquid inlet pipe 72, the U-shaped pipe 73 and the liquid outlet pipe 74 are installed together, and then the liquid inlet pipe 72 and the liquid outlet pipe 74 are installed on two mounting seats 71 on the front of the mounting plate 50, so that the underground heat exchange assembly 70 is installed on the mounting plate 50 and is connected to the heat response tester 20 through a hose 77. According to the size of the test hole, the drive motor 42 inside the fixed seat 30 is started, so that the output shaft of the drive motor 42 drives the bidirectional lead screw 41 inside the fixed seat 30 to rotate, so that the bidirectional lead screw 41 drives the two moving blocks 43 threadedly connected thereto to slide inside the groove 60. The groove 60 limits the moving blocks 43 to prevent the moving blocks 43 from rotating with the bidirectional lead screw 41. The two moving blocks 43 drive the two mounting plates 50 to move towards each other, thereby changing the distance between the two underground heat exchange assemblies 70, so that the two underground heat exchange assemblies 70 can conveniently extend into test holes of different sizes. When the size of the test hole is sufficient, the distance between the two underground heat exchange assemblies 70 can be increased to reduce the mutual influence between the two underground heat exchange assemblies 70 and prevent the occurrence of phenomena such as thermal short circuit. When heat response tests need to be carried out on rock and soil bodies at different heights, the valves 76 at both ends of the U-shaped pipe 73 are closed, so that the liquid inlet pipe 72 and the liquid outlet pipe 74 are directly connected through the connecting pipe 75 to carry out heat response tests on rock and soil bodies at different heights.

Thus, if these modifications and variations of this application fall within the scope of the claims of this application and their equivalent technologies, this application is also intended to include these modifications and variations.

Anyone familiar with the technical field of this application within the technical scope disclosed by this application, according to the technical solution and its concept of this application, makes equivalent substitutions or changes, and should be covered by the protection scope of this application.
