It should be understood that the described embodiments are only some embodiments of the invention, and not all embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.

The groove is fixedly arranged above the guide rail mounting groove, and the length direction of the groove is parallel to the length direction of the guide rail 2.
The power supply unit 4 can realize the dual functions of traction and braking, so that the moving object has the capabilities of acceleration and deceleration. In the whole process that the rotor 402 moves on the rotor motion track formed by the stator 401, the relative positions of the rotor 402 and the stator 401 are continuously adjusted according to information fed back by the power control module 405, the positions of the stator 401 and the rotor 402 are opened in the required trending direction according to needs, excitation current is supplied, the stator 401 and the rotor 402 are closed in the unnecessary trending direction, and the excitation current is reduced or stopped so as to achieve the aim of controlling the sliding speed of the whole water pressure measuring device by matching with the speed measuring unit 8.
