DETAILED DESCRIPTION

[0018] The present invention will be further described below with reference to specific embodiments. It should be understood that these embodiments are intended only to illustrate the present invention and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the contents of this invention, those skilled in the art may make various changes or modifications to the present invention, and that these equivalent forms also fall within the scope defined in this application.

[0019] Example: As shown in the attached Figure 1-4As shown, the utility model is a construction measurement device, including a base 1, the bottom of the base 1 is provided with a universal wheel, one end of the base 1 is provided with a handrail, the top of the base 1 is provided with a mounting plate 2, and the mounting plate 2 is provided with a hoisting device 4 for retracting and releasing a measuring ruler 3. The hoisting device 4 includes a motor and a rotating rod connected to the motor, and supports are provided on both sides of the rotating rod. The rotating rod is rotatably connected to the supports, and the supports are fixed to the mounting plate 2 by screws. One end of the measuring ruler 3 is fixed to the rotating rod by a U-bolt. When the motor is started, it can drive the rotating rod to rotate, thereby retracting or releasing the measuring ruler 3.

[0020] A through hole 5 adapted to the measuring ruler 3 is vertically provided on the mounting plate 2, and a cleaning cylinder 6 is provided on the lower side of the through hole 5. The top end of the cleaning cylinder 6 is fixed to the bottom of the mounting plate 2. The cleaning cylinder 6 can be directly welded to the bottom of the mounting plate 2, or a flange can be welded on the top of the cleaning cylinder 6, and the flange is fixed to the bottom of the mounting plate 2 by screws. The axis of the cleaning cylinder 6 coincides with the axis of the through hole 5, and the measuring ruler 3 passes through the through hole 5 and the cleaning cylinder 6 from top to bottom.

[0021] An annular tube 7 and bristles 8 are provided on the inner wall of the cleaning cylinder 6 from top to bottom. The annular tube 7 can be directly welded to the inner wall of the cleaning cylinder 6. The bristles 8 can be fixed on the circular ring, and the circular ring is fixed to the inner wall of the cleaning cylinder 6 by screws. Several nozzles 71 connected to the annular tube 7 are installed on the inner wall of the annular tube 7. The measuring ruler 3 passes through the cleaning cylinder 6, and the bristles 8 fit the measuring ruler 3. The annular tube 7 is connected to the water pump 9 through a first pipeline 72. The water pump 9 is connected to the water tank 10 through a second pipeline 91. The end of the second pipeline 91 away from the water pump 9 is located at the bottom of the water tank 10.

[0022] The weight of the plumb bob 11 is used to keep the measuring ruler 3 in a vertical position. Preferably, a detachable plumb bob 11 is provided at one end of the measuring ruler 3 away from the hoisting device 4 , and the plumb bob 11 can be removed.

[0023] Furthermore, in order to facilitate the disassembly and assembly of the plumb bob, a mounting seat 12 is provided at the end of the measuring ruler 3 away from the hoisting device 4, and a mounting groove is provided at the bottom of the mounting seat 12. A fixing block 13 adapted to the mounting groove is provided on the top of the plumb bob 11, and mounting holes adapted to the bolt 14 are provided on the fixing block 13 and the mounting seat 12. After the fixing block 13 is inserted into the mounting groove, the fixing block 13 is locked in the mounting groove by the bolt 14, the nut is loosened and removed, and then the bolt 14 is removed from the mounting hole on the fixing block 13, thereby releasing the limit on the fixing block 13, and then the plumb bob 11 can be removed, thereby realizing the detachable function of the plumb bob 11.

[0024] Preferably, a water inlet 15 is provided on one side of the top of the water tank 10, and a removable sealing cap 16 is provided on top of the water inlet 15. The water inlet 15 allows water or cleaning fluid to be injected into the interior of the water tank 10 through the water inlet 15. The inner wall of the sealing cap 16 is internally threaded, while the outer wall of the water inlet 15 is externally threaded. The water inlet 15 and the sealing cap 16 are connected by a threaded connection. By providing the sealing cap 16, after water or cleaning fluid is injected, the sealing cap 16 is installed within the water inlet 15, thereby preventing foreign matter from falling into the interior of the water tank 10.

[0025] When the utility model is in use, the entire device is first moved so that the plumb bob 11 corresponds to the position of the drill hole, and then the motor is started. The motor can drive the rotating rod to rotate, and the rotating rotating rod can release the rope of the measuring ruler 3, so that the plumb bob 11 moves vertically downward. When the plumb bob 11 reaches the end point, the motor stops releasing the rope, and then the measured data can be recorded.

[0026] When the measuring ruler 3 is being retracted, the brush 8 can clean off debris such as dust and soil particles attached to the surface of the measuring ruler 3. In order to further enhance the cleaning effect, the water pump 9 transports the water or cleaning liquid in the water tank 10 to the inside of the annular tube 7, and then the nozzle 71 sprays the water or cleaning liquid on the brush 8 and the measuring ruler 3, so that more stubborn debris can be easily cleaned off.

[0027] When disassembling the plumb bob 11 , the nut is loosened and removed, and the bolt 14 is then removed from the mounting hole on the fixing block 13 , thereby releasing the position restriction on the fixing block 13 , and the plumb bob 11 can then be disassembled.
