DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Embodiment 1 See also Figure 1-Figure 13The present invention provides a pollution source monitor, comprising a monitor body 1 with a flow hole and a filter residue screen cylinder 2 located in the monitor body 1 (an inner cavity is provided in the monitor body 1, and the size of the inner cavity is larger than the filter residue screen cylinder 2, so that the filter residue screen cylinder 2 can move in the inner cavity), a self-rotating rod 3 rotatably connected to the filter residue screen cylinder 2 is movably matched in the monitor body 1, a counterweight block 4 is movably matched on the self-rotating rod 3, a circulation plate 5 connected and fixed to the self-rotating rod 3 is movably matched on the inner wall of the filter residue screen cylinder 2, a pressure column 6 matched with the circulation plate 5 is provided on the counterweight block 4, and a wireless sensor for detecting water quality is provided below the filter residue screen cylinder 2. In the present application, the wireless sensor comprises a power supply module, a water quality detection module, a wireless transmission module, a control module, a PH probe for real-time detection, and a power switching module. The wireless transmission module sends the water quality detection data obtained by the water quality detection module to an external control center in real time, and the power supply module comprises a rechargeable battery, a charging management module, and a primary battery pack; It also includes a shaking assembly, which makes the filter residue screen cylinder 2 and the circulation plate 5 shake up and down through the self-rotating rotation rod 3 and the counterweight block 4, and the circulation plate 5 reciprocating along the direction of the self-rotating rod 3 is in gap with the filter residue screen cylinder 2; a matching assembly, which is used for the counterweight block 4 to move up and down, and cooperates with the pressure column 6 to synchronously act on the filter residue located in the circulation plate 5; The shaking assembly includes two fixed plates 7 connected and fixed to the monitoring instrument body 1, and a movable groove 8 is opened on the fixed plate 7. A slider 9 is slidably matched in the movable groove 8. A compression spring 10 is hung between the top and bottom of the slider 9 and the movable groove 8. The self-rotating rod 3 passes through the slider 9, and a limiting cylinder 11 rotatably connected to the filter residue screen cylinder 2 is fixedly connected to one of the sliders 9, and a power piece is provided at the end of the self-rotating rod 3; In the present application, the power member makes the self-rotating rod 3 rotate, and under the action of the counterweight block 4, the self-rotating self-rotating rod 3 drives the slider 9 to swing up and down along the movable groove 8 under the action of the compression spring 10, thereby driving the filter residue screen cylinder 2 and the circulation plate 5 to swing up and down, wherein the circulation plate 5 is connected and fixed to the self-rotating rod 3, so that the circulation plate 5 makes a continuous circular motion in the filter residue screen cylinder 2, thereby dispersing the solid debris, making the debris move along the circulation plate 5, and the liquid is removed through the through hole on the filter residue screen cylinder 2; It is worth noting that the limiting cylinder 11 does not rotate when the slider 9 moves up and down, so that the mixed liquid can enter the filter residue screen cylinder 2 easily.

[0022] The shaking assembly also includes a slide column 12 connected and fixed to the slider 9, an elliptical groove 13 is provided on the outer surface of the rotating rod 3 to slide with the slide column 12, rolling rings 14 are fixedly connected to both ends of the filter residue screen cylinder 2, and a rolling plate 15 rolling with the rolling ring 14 is fixedly installed on the monitoring instrument body 1. When the filter residue screen cylinder 2 moves up and down, the rolling ring 14 rolls along the rolling plate 15, so that the filter residue screen cylinder 2 moves up and down while reciprocating at a certain angle, so that the filter residue screen cylinder 2 swings back and forth to disperse the mixed liquid inside the filter residue screen cylinder 2, which is convenient for solid-liquid separation. Compared with the dispersion of the mixed liquid by the filter residue screen cylinder 2 that continuously performs a circular motion, the reciprocating dispersion method is more helpful to keep the solid and liquid away from each other, thereby increasing the separation effect; The slider 9 moves vertically up and down along the movable groove 8, and the horizontal position of the slider 9 does not change, while the self-rotating rod 3 rotates, and through the action of the inclined elliptical groove 13 and the sliding column 12, the self-rotating self-rotating rod 3 reciprocates through the slider 9 in the horizontal direction, thereby driving the circulation plate 5 to reciprocate. The circulation plate 5 reciprocates relative to the filter residue screen cylinder 2, changing the distance between the circulation plate 5 and the filter residue screen cylinder 2, so that the gap between the circulation plate 5 and the filter residue screen cylinder 2 is sometimes large and sometimes small, thereby facilitating the movement and dispersion of the crushed residue; When the self-rotating rod 3 reciprocates, the hinge plate 19 rotates, and the hinge plate 19 slides along the sliding groove 18 in an adaptive and adjustable manner, so that the self-rotating rod 3 reciprocates while ensuring the self-rotation and up and down shaking of the self-rotating rod 3.

[0023] The power part includes a motor 16 connected and fixed to the monitoring instrument body 1, the output shaft of the motor 16 is fixedly connected to a rotating plate 17, the rotating plate 17 is provided with a cross-shaped sliding groove 18, the end of the self-rotating rod 3 is hinged to two hinge plates 19 that are symmetrically distributed and penetrate into the sliding groove 18, and the end of the hinge plate 19 is fixedly connected to a sliding rod 20 that slides with the sliding groove 18; The motor 16 runs, driving the rotating plate 17 to rotate, and the rotating rod 3 rotates through the hinged plate 19. Under the action of the counterweight 4, the rotating rotating rod 3 swings up and down along the movable groove 8 at the same time. At this time, the axis of the rotating rod 3 does not coincide with the axis of the output shaft of the motor 16. The hinged plate 19 and the sliding rod 20 move adaptively along the sliding groove 18 at the same time to ensure the rotation movement.

[0024] The matching component includes a connecting plate 21, the two ends of which are respectively connected and fixed to the pressure column 6 and the counterweight block 4, and a sliding groove 22 that is slidably matched with the connecting plate 21 is provided on the rotation rod 3, and the pressure column 6 and the counterweight block 4 are pressed and matched; During the rotation of the rotating rod 3, the connecting plate 21 is driven to move up and down along the slide groove 22, and the pressure column 6 and the counterweight block 4 move up and down synchronously, and the pressure column 6 and the counterweight block 4 move synchronously in coordination with the rotating rod 3 that moves up and down, so that the pressure column 6 and the counterweight block 4 that move up and down are inserted into the debris located on the circulating plate 5 to disperse the debris.

[0025] The counterweight block 4 is fan-shaped, and is provided with a plurality of slots 23 (the slots 23 on both sides are obliquely distributed). The slots 23 cooperate with the circulation plate 5, and the mixed liquid on the circulation plate 5 is inserted through the plurality of slots 23, thereby dispersing the liquid and the solid, and separating the solid and the liquid. It is worth noting that in this solution, the movement of the counterweight block 4 and the pressure column 6 relative to the rotating rod 3, on the one hand, changes the up and down shaking amplitude of the rotating rod 3 to increase the effect of dispersing solids and liquids, and on the other hand, further disperses the moving debris on the circulating plate 5.

[0026] The inner cavity size of the monitoring instrument body 1 is larger than that of the filter residue screen cylinder 2, and the length of the chute 22 is larger than that of the counterweight block 4, so as to facilitate the movement of the filter residue screen cylinder 2 and the counterweight block 4; The circulation plate 5 is provided with evenly distributed water-permeable holes to avoid water accumulation and ensure that the debris moves away from the circulation plate 5 .

[0027] Embodiment 2 The second embodiment is a further supplement and explanation of the first embodiment. The limiting cylinder 11 is fixedly connected with an inclined plate 24 inside. The limiting cylinder 11 is fixedly connected with a conveying hose 25 passing through the monitoring instrument body 1 (one end of the conveying hose 25 is connected to the flow hole on one side of the monitoring body 1, and the other end is provided with a pumping device for sucking the mixed liquid). The mixed liquid is conveyed into the limiting cylinder 11 through the conveying hose 25. The limiting cylinder 11 does not rotate, but only moves up and down with the slider 9, and cooperates with the inclined plate 24 to allow the mixed liquid to enter the filter residue screen cylinder 2, and separate and remove the residue. A liquid collecting pipe 26 for collecting liquid is provided below the filter residue screen cylinder 2 (the liquid collecting pipe 26 is connected to the inner cavity), and the wireless sensor is located in the liquid collecting pipe 26. A slag collecting cylinder 27 for collecting broken slag is fixedly installed below the outlet end of the filter residue screen cylinder 2 and passes through the monitoring instrument body 1. The liquid collecting pipe 26 and the slag collecting cylinder 27 are located on the flow hole on the other side of the monitoring body 1. It is worth noting that the elliptical groove 13 corresponds to the position of the conveying hose 25, and the elliptical groove 13 on the self-rotating rotating rod 3 acts on the mixed liquid entering the limiting cylinder 11, wherein the sliding cooperation between the sliding column 12 and the elliptical groove 13, on the one hand, prevents the mixed liquid from overflowing therefrom, and on the other hand, mobilizes the mixed liquid and prevents the solid extraction debris from accumulating in the elliptical groove 13.

[0028] The outer surface of the filter residue screen cylinder 2 is fixedly connected with an inclined baffle 28 , which is located between the liquid collecting pipe 26 and the residue collecting cylinder 27 to prevent the liquid screened by the filter residue screen cylinder 2 from flowing from the outer surface of the filter residue screen cylinder 2 into the residue collecting cylinder 27 .

[0029] The horizontal cross-sectional shapes of the slider 9 and the movable groove 8 are in a mutually adapted "+" shape, ensuring that the slider moves up and down along the movable groove 8, thereby driving the filter residue screen drum 2 to move.

[0030] The length of the connecting plate 21 close to the limiting cylinder 11 is greater than the length of the connecting plate 21 far from the limiting cylinder 11 , so as to ensure that the counterweight 4 acts reciprocatingly in the circulating plate 5 .

[0031] Embodiment 3 See also Fig.14 The matching component includes a connecting plate 21, one end of the connecting plate 21 is connected to the pressure column 6, and the other end is hingedly matched with the counterweight block 4. A sliding groove 22 that slides with the connecting plate 21 is penetrated on the rotating rod 3, and the pressure column 6 and the counterweight block 4 are pressed and matched.

[0032] In this embodiment, compared with the first embodiment, the connection relationship between the counterweight block 4 and the connecting plate 21 is adjusted from a fixed connection to a hinged connection, so that when the pressure column 6 and the counterweight block 4 move up and down, the pressure column 6 and the counterweight block 4 are hingedly matched with the connecting plate 21, so that the inclination angle and position of the counterweight block 4 and the pressure column 6 (relative to the angle and position of the rotating rod 3) are adjusted, thereby further flexibly acting on the debris located on the circulating plate 5.

[0033] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
