The sliding portion 13 includes a sliding cavity 130 provided with a sliding bolt 132, the strong magnetic slider 125 drives the sliding bolt 132 to slide left and right when sliding up and down, and the sliding bolt 132 drives the cleaning assembly 11 to slide up and down.

In this embodiment, the control portion 12 controls the strong magnetic slider 125 to slide up and down through the magnetic repulsion or attraction, so as to drive the valve rod 122 to slide up and down, and control the fluid passing through the stop valve portion 102 through the plug portion 1220.

The shut-off valve portion 102 is provided with a fluid hole, and the hole and the plug portion 1220 can be closed when contacting. By controlling the magnitude and direction of the current acting on the electromagnet 123 and combining the action of repulsion or attraction with the magnetism of the strong magnetic slider 125, the sliding of the strong magnetic slider 125 is controlled, and the blocking head 1220 slides up and down to control the opening or closing of the cut-off valve part 102 under the driving of the valve supporting rod 122, so as to control the passing or stopping of the water flow.

When the strong magnetic slider 125 slides up and down, the sliding bolt 132 is triggered to synchronously slide left and right, and the cleaning component 11 synchronously slides up and down due to the fall area arranged on the outer shell of the sliding bolt 132.

As shown in fig. 2, an embodiment of the present invention includes controlling the magnitude and direction of the current applied to the electromagnet 123, so that the electromagnet 123 and the strong magnetic slider 125 generate magnetic repulsion, the strong magnetic slider 125 slides downward in the valve control cavity 121, the valve rod 122 slides downward under the driving of the strong magnetic slider 125, the plug portion 1220 is separated from the cut-off valve portion 102, and the fluid can pass through the hole on the cut-off valve portion 102.

Meanwhile, when the strong magnetic slider 125 slides downwards, the sliding bolt 132 is touched, so that the sliding bolt 132 slides rightwards in the sliding cavity 130, the sliding bolt 132 drives the cleaning component 11 to push upwards in the sliding process, and the cleaning component 11 is close to and contacts the measuring area of the sensor 2. When liquid passes through the pipeline, the liquid impacts and drives the cleaning component 11 to clean and brush the sensor 2.

Referring to the enlarged partial views of figures 3 and 4,

in this embodiment, one or both ends of the strong magnetic slider 125 are in a semicircular, elliptical or arc structure. Two ends of the strong magnetic slider 125 contact the inner wall of the valve control cavity 121 and can slide up and down along the inner wall of the valve control cavity 121.

A sliding stop block is further arranged in the valve control cavity 121 and used for preventing the downward sliding track of the strong magnetic slider 125 from being too long.

In this embodiment, a first spring 124 is further disposed in the valve control chamber 121, one end of the first spring 124 is connected to the bottom of the inner side of the valve control chamber 121, and the other end is connected to the strong magnetic slider 125. The valve supporting rod 122 passes through the first spring 124 from the middle, when the valve control chamber 121 slides downwards, pressure acts on the first spring 124, the first spring 124 is compressed to play a role in buffering, and when the electromagnet 123 and the strong magnetic slider 125 instantaneously generate magnetic repulsion action, the impact force of the strong magnetic slider 125 is reduced through the first spring 124.

In one embodiment of this embodiment, when the electromagnet 123 is not energized and the electromagnet 123 is not magnetic, the first spring 124 presses upward against the strong magnetic slider 125 by its own elastic force, so that the plug portion 1220 of the valve rod 122 also presses against the hole of the shut-off valve portion 102, and the hole is closed to prevent the liquid from passing through.

In the present embodiment, when no control is applied, that is, when no external force control is applied, the water inlet passage 101 is automatically in the cutoff state, and the fluid such as water flow is prohibited from passing through the cutoff valve portion 102.

In this embodiment, the valve control chamber 121 communicates with the sliding chamber 130, and one end of the sliding bolt 132 may partially extend into the valve control chamber 121. One end of the sliding bolt 132 is a semicircular, oval or arc structure, and the other end is an arc structure having an up-down fall area. A second spring 131 is further disposed in the sliding cavity 130, one end of the second spring 131 is connected to the inner side of the sliding cavity 130, and the other end is connected to the sliding bolt 132. The sliding pin 132 is moved leftward by the elastic force of the second spring 131, and one end portion of the sliding pin 132 is inserted into the sliding chamber 130.

When the strong magnetic slider 125 slides downward, wherein one end of the semicircular, oval or arc structure has an arc surface, against one end of the sliding bolt 132 also having an arc surface, the sliding bolt 132 slides rightward, compressing the second spring 131, and the second spring 131 is the same as the first spring 124, until the impact force is buffered.

At this time, the other end of the sliding bolt 132 acts on the cleaning shaft 110 of the cleaning assembly 11 through an arc structure having an upper and lower drop height area, the cleaning shaft 110 moves upward along the end surface of the arc structure moving to the right side synchronously, and the cleaning assembly 11 also approaches the sensor 2 gradually. When the cut-off valve portion 102 enters the fully opened state, the cleaning assembly 11 contacts the sensor 2, and when fluid such as water flows in the pipeline, the cleaning assembly 11 is driven to rotate and brush.

As shown in fig. 5 and 6, the cleaning assembly 11 includes a rotatable cleaning impeller 111, the cleaning impeller 111 is fixedly connected to a cleaning shaft 110, and a lower end of the cleaning shaft 110 abuts against the sliding bolt 132. The pipeline main body 1 is provided with a hole, the hole is communicated with the sliding cavity 130, the cleaning shaft 110 is arranged in the hole, the cleaning shaft 110 can move up and down, and the lower end of the cleaning shaft is provided with an arc structure for sliding along the arc structure of the sliding bolt 132 with an upper and lower fall area. The connection of the holes is provided with a sealing portion 100 for installing a seal to prevent fluid from overflowing.

Referring to fig. 7, the upper end of the cleaning shaft 110 is connected to a cleaning sheet assembly 112, the cleaning sheet assembly 112 includes a brush rod, and a plurality of soft bristles are arranged on the brush rod. The cleaning impeller 111 is a multi-bladed rotatable impeller. When fluid such as water flow passes through the channel, the fluid impacts the cleaning impeller 111, the cleaning impeller 111 rotates around the cleaning shaft 110, and the cleaning shaft 110 drives the cleaning blade assembly 112 to rotate. As shown in fig. 6, when the cleaning shaft 110 is pushed up against the sensor 2 by the sliding bolt 132, the rotating cleaning blade assembly 112 brushes the sensor measuring part 201 of the sensor 2 by the soft bristles arranged thereon, and is washed by a fluid such as water flow.

Referring to fig. 3 or 4, a buffer pad 126 is further disposed between the electromagnet 123 and the strong magnetic slider 125.

As shown in fig. 8, the lengths or heights of the water inlet passage 101, the valve control chamber 121, the valve support rod 122, the sliding bolt 132 and the partial region of the cleaning assembly 11 are implemented according to one or more of the following rules:

rule 1: the a1 length of the valve strut 122 coincides with the a2 or A3 length of the valving cavity 121;

rule 2: the height B1 of the water inlet channel 101 is consistent with the height B2 of the sliding bolt 132;

rule 3: the C1 length of the sliding pin 132 corresponds to the C2 length.

In this embodiment, when the choke plug portion 1220 and the stop valve portion 102 are closed, the length a1 of the portion of the valve supporting rod 122 extending therefrom, corresponding to the distance A3 between the valve supporting rod 122 and the bottom of the valve control chamber 121, is the same, and is used for limiting the position of the strong magnetic slider 125 and the valve supporting rod 122 when they slide downward, so as to prevent the choke plug portion 1220 from being damaged.

At the same time, the a1 also coincides with the a2 length of the valve control chamber 121, and a slide stop is provided to stop the strong magnetic slider 125 from continuing to slide downward, also until the function of a limit. On the other hand, when the ferromagnetic slider 125 slides upward from the slide stopper, the longest sliding distance is also a2, which is the same as a1, and thus the function of protecting the shut-off valve portion 102 is achieved, and the shut-off valve portion 102 is prevented from being damaged by the shut-off head portion 1220. Meanwhile, the first spring 124, the cushion pad 126 and the second spring 131 also play a certain role in buffering.

When the cleaning assembly 11 is at the bottom, that is, when the cleaning shaft 110 is at the lowest position of the arc structure in the drop height area of the sliding bolt 132, the length C1 of the portion of the sliding bolt 132 extending into the valve control chamber 121 may be the same as the length C2 of the arc vertical projection of the arc structure in the drop height area of the sliding bolt 132, or C1 may be longer than C2.

When the sliding bolt 132 is pushed by the strong magnetic slider 125 to move rightwards, the cleaning shaft 110 follows the arc-shaped structure and pushes upwards, and when the part of the sliding bolt 132 extending into the valve control cavity 121 is completely moved back to the inside of the sliding cavity 130, the cleaning shaft 110 is also at the highest position of the arc-shaped structure of the sliding bolt 132, and the cleaning assembly 11 contacts the bottom measuring area of the sensor 2.

The invention also comprises an electric part or an intelligent control part.

According to the fluid measuring pipeline device provided by the invention, when the fluid is not required to be measured or no fluid passes through the measuring pipeline, the cleaning assembly is automatically separated from the sensor and keeps a certain distance, so that the phenomenon that dirt is attached to the sensor due to long-time contact to influence the measuring result is avoided.
