Description

Technical Field

[0001] The utility model relates to the technical field of water supply network water affairs inspection, in particular to a valve split-type intelligent circle counter under special working conditions. Background Art

[0002] In the management of urban infrastructure, the inspection of water supply networks is crucial because it is directly related to the safety and operational efficiency of urban water supply. In routine water inspections, water inspectors are required to perform specific operations on the inspection targets to detect the targets and collect the target data. Specifically, the valve of the detection target is rotated to a certain rotation angle and number of turns, and the data of the detection target is collected. Since this operation is related to the data collected during the detection, there are certain process requirements for the measurement of the valve rotation angle. At present, conventional angle measuring equipment is of two types: roller type and encoder type. Among them, encoders have higher accuracy and are commonly used in motors and other equipment. However, these two types of equipment are not suitable for the existing working conditions of water supply pipelines and cannot be used in underwater environments. In addition, there are problems with the waterproofness and recognition reliability of these two types of metering equipment in long-term water immersion environments. Utility Model Content

[0004] In order to achieve the above-mentioned purpose, a split-type intelligent valve circle counter for special working conditions is designed, comprising a movable module, which is connected to the valve adapter and rotates with the valve, and a plurality of permanent magnets are provided on the movable module at equal intervals along the circumferential direction; a fixed module, which is fixedly mounted on the valve body, and an induction probe is provided on the fixed module, and the induction probe is used to obtain a pulse signal when a permanent magnet passes directly above it.

[0007] An L-shaped connecting plate is provided on one side of the fixing module. One side of the L-shaped connecting plate is connected to the valve body, and the other side of the L-shaped connecting plate is provided with a sensing probe.

[0008] Compared with the prior art, the utility model has the following technical effects:

BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 The schematic diagram of the structure of the valve split-type intelligent circle counter of the utility model is shown.

[0013] In the figure: 1 movable module; 1.1 connecting base; 1.2 rotating body; 1.3 permanent magnet; 2 fixed module; 2.1 L-shaped connecting plate; 2.2 induction probe; 2.3 valve body. DETAILED DESCRIPTION

[0014] As shown in the figure, this embodiment provides a valve split-type intelligent circle counter under special working conditions, which mainly includes a movable module 1 and a fixed module 2.

[0015] The movable module 1 includes a connection base 1.1, wherein a sleeve structure is provided in the middle of the connection base 1.1 for matching the connection valve adapter, and the connection base 1.1 rotates together with the valve when the valve rotates. A rotating body 1.2 fixed to the connection base 1.1 is sleeved on the outside of the connection base 1.1, and the rotating body 1.2 rotates together with the valve adapter. Six permanent magnets 1.3 are provided in the circumferential direction of the rotating body, and the six permanent magnets 1.3 are evenly and symmetrically distributed on the rotating body 1.2 with the sleeve in a circular shape.

[0016] The fixing module 2 has an L-shaped connecting plate 2.1 on one side, one side of the L-shaped connecting plate 2.1 is connected to the valve body 2.3, and the other side thereof is provided with a sensing probe 2.2, and the sensing probe 2.2 is used to obtain a pulse signal when the permanent magnet 1.3 passes directly above.

[0017] When the maintenance personnel rotate the valve, the valve adapter rotates accordingly, and the connection base 1.1 connected to the valve adapter and the rotating body 1.2 fixedly connected to the outside of the sleeve of the connection base 1.1 also rotate with the valve adapter. The six permanent magnets 1.3 on the rotating body 1.2 can be numbered 1-6 respectively. When the rotating body 1.2 rotates, the corresponding permanent magnets 1.3 No. 1-6 pass through the induction probe 2.2 connected to one side of the fixed module 2 in sequence. The induction probe 2.2 measures the pulse signal generated by the permanent magnet 1.3 as it rotates, and identifies the serial number of the permanent magnet 1.3.

[0018] When the induction probe 2.2 detects that the serial numbers of the permanent magnets 1.3 are arranged in positive order, the valve rotates clockwise at this time; conversely, when the induction probe 2.2 detects that the serial numbers of the permanent magnets 1.3 are arranged in reverse order, the valve rotates counterclockwise at this time.

[0019] When the induction probe 2.2 detects a pulse signal from a permanent magnet 1.3, it indicates that the valve has rotated 60 degrees; when the induction probe 2.2 detects pulse signals from two permanent magnets 1.3, it indicates that the valve has rotated 120 degrees; and so on, when the induction probe 2.2 detects pulse signals from six permanent magnets 1.3, it indicates that the valve has rotated 360 degrees, that is, the valve has rotated one circle.

[0020] Therefore, the direction of valve rotation, the angle of valve rotation, and the number of valve rotations can be calculated through the pulse signal data obtained by the sensing probe 2.2, so as to monitor whether the inspection personnel have performed compliant operating behaviors. At the same time, there is no need to set up another supervisor to monitor whether the inspection personnel's operating behaviors are compliant. Example

[0021] In this embodiment, when a maintenance task occurs, the staff arrives at the maintenance target and starts to rotate the valve according to the maintenance requirements. The valve rotates, driving the valve adapter to rotate, the valve adapter drives the movable module 1 to rotate, and the movable module 1 drives the rotating body 1.2 to rotate. The permanent magnet 1.3 passes over the induction probe 2.2 in sequence, and the induction probe 2.2 receives the pulse signal generated by the permanent magnet 1.3. Based on the pulse signal, the information that the staff rotates the valve can be read.

[0022] When the induction probe 2.2 detects that the serial numbers of the permanent magnets 1.3 are arranged in positive order, the valve rotates clockwise at this time; conversely, when the induction probe 2.2 detects that the serial numbers of the permanent magnets 1.3 are arranged in reverse order, the valve rotates counterclockwise at this time.

[0023] When the induction probe 2.2 detects a pulse signal from a permanent magnet 1.3, it indicates that the valve has rotated 60 degrees; when the induction probe 2.2 detects pulse signals from two permanent magnets 1.3, it indicates that the valve has rotated 120 degrees; and so on, when the induction probe 2.2 detects pulse signals from six permanent magnets 1.3, it indicates that the valve has rotated 360 degrees, that is, the valve has rotated one circle.

[0024] If the number of valve rotations, direction, and angle in the read valve information are consistent with the required operation, the inspection personnel have completed the inspection work; if the read information is inconsistent with the required operation, the inspection personnel have not completed the inspection work.

[0025] The above is only a specific implementation method of this utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field within the technical scope disclosed by the utility model, according to the technical solution and new concept of the utility model, shall be covered by the protection scope of the utility model.
