Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a device for measuring the height of mud at the bottom of a well and the size of a pipe opening in the well. Background Art

[0002] As a crucial component of the drainage system, the functionality of inspection wells directly impacts the drainage network's ability to transport wastewater. Currently, the industry's most common method for measuring bottom sludge involves inserting a rigid rod into the well and measuring the height of the sludge adhering to the rod's surface with a tape measure. However, the depth of drainage inspection wells varies depending on the buried depth of the drainage pipeline. Previous methods for measuring bottom sludge are not universally applicable and suffer from low accuracy. Furthermore, the method of first draining and then measuring is costly and time-consuming, making it unsuitable for practical engineering applications.

[0003] Measuring existing pipeline dimensions at high water levels is an essential step in geophysical investigations, and the accuracy of the data significantly impacts design. Currently, the industry can employ instrumentation (such as sonar) to investigate existing pipelines at high water levels. However, this approach is costly and requires specialized personnel, making it unsuitable for universal use. Alternatively, manual inspection can be employed, where the existing pipeline is sectioned and then measured downhole to determine the existing pipe openings. However, this method is inefficient and poses safety risks. Utility Model Content

The handwheel group 1 rotates under the action of external force to drive the traction rope 3 to wind or unfold on the handwheel group 1 to adjust the movement of the outer tube 2.3 along the inner tube 2.2, thereby adjusting the distance between the telescopic plate 5 and the telescopic rod 10.

[0025] For further information, see Figure 3 、 5 The inner tube 2.2 is a polished rod, the outer tube 2.3 is a hollow tube, and the inner tube 2.2 and the outer tube 2.3 are coaxially arranged.

[0026] Preferably, a connection port 4 is provided between the inner tube 2.2 and the outer tube 2.3.

[0027] For further information, see Figure 2 The handwheel assembly 1 includes a connecting member 1.1 connected to the inner tube 2.2, a rotating shaft 1.2 rotatably arranged in the connecting member 1.1, a roller counter 1.3 arranged on the rotating shaft 1.2, a wire groove 1.4 is provided on the rotating shaft 1.2, and a hand wheel 1.5 is provided at the end of the rotating shaft 1.2 away from the fixing member 6.

[0034] In this embodiment, the device enters the inspection well vertically when the support assembly 2, telescopic plate 5, and telescopic rod 10 are in the retracted state.

Since the pulley group 8 is fixed on the outer tube 2.3 and remains relatively stationary with the outer tube 2.3, that is, the elongation length of the traction rope 3 is the height to which the outer tube 2.3 slides downward, the height of the sludge at the bottom of the inspection well can be measured.

[0035] When the support assembly 2, telescopic plate 5 and telescopic rod 10 are in the retracted state, the device enters the inspection well vertically. When the telescopic plate 5, telescopic rod 10 are in the same horizontal plane as the pipe opening in the well, the motor 11.6 is started, so that the telescopic plate 5 and telescopic rod 10 are extended outward along the rack 11.2 under the drive of the gear 11.4; the position of the device is adjusted so that the telescopic plate 5 and telescopic rod 10 enter the pipe opening in the inspection well and the upper surface of the telescopic plate 5 is close to the inner top of the pipe opening; the handwheel is turned and the pulley group 8 is adjusted to change the length of the traction rope 3 and control the outer tube 2.3 to slide downward so that the bottom of the telescopic rod 10 is close to the inner bottom of the pipe opening; the roller counter 1.3 can calculate the elongation length of the traction rope 3 according to the number of rotations of the handwheel. Since the pulley group 8 is fixed on the outer tube 2.3 and remains relatively stationary with the outer tube 2.3, that is, the elongation length of the traction rope 3 is the height of the outer tube 2.3 sliding downward, the size of the pipe opening in the inspection well can be measured.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
