The invention relates to a detection device for a low-temperature geothermal sleeve. The device comprises a water tank, a heating mechanism, a circulating pump, a PID controller, a test pipe section,a first temperature sensor, a second temperature sensor and a third temperature sensor group. The heating mechanism is fixed inside the water tank, an outlet of the water tank is connected to an inletof the circulating pump through a first conveying pipeline, an outlet of the circulating pump is connected to an inlet of the test pipe section through a second conveying pipeline, and an outlet of the test pipe section is connected to an inlet of the water tank through a third conveying pipeline. The first temperature sensor is fixed at the inlet position of the test pipe section, and the outputend of the first temperature sensor is connected with the interface of the set end of the PID controller. The second temperature sensor is fixed in the water tank, and the output end of the second temperature sensor is connect
