[0029] In this embodiment, the detection unit includes four connection boxes 33, and a cavity 31 is provided at the bottom of the mounting column 3. The bottom of the cavity 31 is a concave structure with a low middle and high sides. Four connection holes 32 are provided on the cavity wall of the cavity 31 in a circular array. The four connection boxes 33 are installed on the mounting column 3, and the cavity 31 is connected to the connection box 33 through the four connection holes 32 respectively. A pair of conductive blocks 34 is provided on the inner wall of each connection box 33, and each pair of conductive blocks 34 is electrically connected to the control circuit of the motor 42 at the adjacent position.

[0030] In this embodiment, a liquid storage chamber 35 is provided at the top of the mounting column 3, and a sealing plate 351 is sealed and slidably connected in the liquid storage chamber 35. A liquid guide tube 36 is embedded in the wall of one side of the liquid storage chamber 35.

[0031] In this embodiment, electrorheological fluid is provided in the base 2 and all the fixed rods 21. Conductive coils are embedded in the base 2 and the fixed rods 21 to provide an electric field. Under the action of the electric field, the viscosity coefficient of the electrorheological fluid can be significantly enhanced, thereby transforming from liquid to solid. Two symmetrically distributed limit blocks 24 are provided at the upper end of each sliding rod 23.

[0032] In this embodiment, the conductive coil is connected in series with an electromagnetic switch through a wire, the control circuits of the four motors 42 are connected in parallel with each other and are commonly connected in series with an electromagnetic switch controller, and the electromagnetic switch and the electromagnetic switch controller are connected in parallel through a wire and are commonly connected to an external power supply.

[0033] A digital construction measurement method comprises the following steps:

[0034] S1. Place the measuring device at the measuring point;

[0035] S2, connect the measuring device to power and automatically adjust the level;

[0036] S3. Turn on the measuring instrument 1 to measure data.

[0037] The circuit diagram of the present invention is as follows Figure 6 As shown, four motors 42 and corresponding conductive blocks 34 are connected in parallel. When a pair of conductive blocks 34 are connected to power the motor 42, the electromagnetic switch controller in the circuit will also be powered to control the electromagnetic switch to disconnect, thereby de-energizing the circuit where the conductive coil is located.

[0038] The working process and principle of the present invention are as follows:

[0039] When in use, the entire device is first transported to the measuring point. When the device is placed, the multiple slide bars 23 at the bottom of the base 2 will first contact the ground. According to the terrain of the ground, the raised part will first contact and squeeze the slide bar 23. After the slide bar 23 is pressed, it slides up and pushes the electrorheological fluid in the fixed rod 21 into the base 2, and pushes the other slide bars 23 that are not in contact with the ground to slide out through hydraulic transmission. Finally, the multiple slide bars 23 are matched with the ground terrain and the placement is completed. At this time, the equipment is connected to electricity. The conductive liquid in the cavity 31 of the mounting column 3 will detect whether the base 2 is horizontal. If the base 2 is in a horizontal state, the conductive liquid will only be at the bottom of the cavity 31. If the base 2 is in a tilted state, the conductive liquid will flow into the connecting box 33 on the tilted side. The conductive liquid will serve as a conductive medium to connect the conductive block 34 in the connecting box 33, so that the motor 42 on the tilted side is energized and works, and the motor 42 will drive the missing gear 4 7 rotates, and the engagement of the missing gear 47 and the bevel gear 46 drives the rotating block 44 to rotate, and the threaded rod 45 is controlled by the thread to descend so that the support foot 49 touches the ground, so as to lift the base 2 on the inclined side, and gradually reduce the inclination of the base 2 by continuously descending the support foot 49. During the lifting process of the base 2, the conductive coil is in a power-off state, and the electrorheological fluid is in a liquid state. The slide bar 23 under the base 2 will automatically extend or retract with the lifting and match the ground terrain again. When the base 2 returns to a horizontal state, the conductive liquid will flow out of the connection box 33, the conductive block 34 will be disconnected, and the motor 42 will also stop working. At this time, the conductive coil will become energized, and the electrorheological fluid will become solid under the action of the electric field, limiting the extension and contraction of the slide bar 23, so that the base 2 maintains a horizontal and stable state, avoiding shaking during measurement of the measuring instrument 1. After the level adjustment is completed, the measuring instrument 1 can be opened to measure and collect data.

[0040] During use of the device, the control button 372 can be rotated to rotate the control rod 37 according to the required horizontal accuracy of the measuring instrument 1, and the sealing plate 351 can be pushed to slide through the thread, so that the conductive liquid in the liquid storage chamber 35 is squeezed into the cavity 31 through the liquid guide tube 36, thereby increasing the amount of conductive liquid in the cavity 31 and making it easier for the conductive liquid to enter the connection box 33 to connect the conductive block 34 to electricity, thereby increasing the sensitivity of tilt detection. Conversely, the amount of conductive liquid can be reduced.

[0041] Among them, the speed of the motor 42 is set to be slower (it can be matched with a reducer to drive the missing gear 47 to rotate) in order to reduce the descending speed of the support leg 49. The missing gear 47 is used for meshing transmission to make the descent of the support leg 49 pause, thereby leaving more reaction time for the self-adjustment of the slide bar 23 below the base 2, avoiding the support leg 49 from descending too quickly, resulting in over-calibration of the tilt adjustment.

[0042] It is understood from common technical knowledge that the present invention may be implemented by other embodiments that do not depart from its spirit or essential features. Therefore, the embodiments disclosed above are, in all respects, merely illustrative and not exclusive. All modifications within the scope of the present invention or equivalent to the scope of the present invention are intended to be encompassed by the present invention.
