Description

Technical Field

[0001] The present invention relates to the technical field of water pollution monitoring instrument structures, in particular to a pollution source monitoring instrument. Background Art

[0002] Water quality testing is an important means of assessing the health of water bodies. However, prior to testing, separation and pretreatment of water samples is a crucial step. Pretreatment first removes impurities and interferences. Water samples may contain various impurities and interferences, such as sediment, suspended matter, and chlorophyll. These impurities and interferences can directly affect the accuracy of water quality test results. If the water sample contains a large amount of impurities and particulate matter, these impurities and particulates may clog the instrument pipes or damage instrument components.

[0003] For example, a water quality monitoring device with Chinese patent publication number CN218382734U includes a water quality monitor and a cylinder, on which a liquid inlet pipe, a dosing pipe, and a drain pipe are installed. A stirring mechanism is installed on the cylinder, and a screen cylinder is fixedly connected to the lower end of the liquid inlet pipe. A slag discharge pipe is fixedly connected to the lower end of the screen cylinder. The left end of the slag discharge pipe extends outside the cylinder, and a sealing plug is inserted on the left end of the slag discharge pipe.

[0004] This solution facilitates filtering of sewage entering the cylinder by setting a sieve cylinder, preventing larger particles and debris in the sewage from clogging the water inlet pipe of the water quality monitor and affecting the normal operation of the water quality monitor; and facilitates removal of larger particles and debris collected in the sieve cylinder by setting a slag discharge pipe and a sealing plug.

[0005] Although a screen drum device is provided to separate the solid waste, the rotation trajectory of the screen drum is fixed and the movement trajectory cannot be changed, which cannot further improve the separation effect;

[0006] To this end, we propose a pollution source monitor. Summary of the Invention

[0008] To achieve the above-mentioned purpose, the present invention provides a pollution source monitor, comprising a monitor body with a circulation hole and a filter residue screen cylinder located in the monitor body, wherein the monitor body is equipped with a self-rotating rod rotatably connected to the filter residue screen cylinder, the self-rotating rod is movably equipped with a counterweight block, the inner wall of the filter residue screen cylinder is movably equipped with a circulation plate fixedly connected to the self-rotating rod, the counterweight block is provided with a pressure column equipped with the circulation plate, and a wireless sensor for detecting water quality is provided under the filter residue screen cylinder; it also includes a shaking component, which causes the filter residue screen cylinder and the circulation plate to shake up and down through the self-rotating rotating rod and the counterweight block, and at the same time, the circulation plate moving back and forth along the direction of the self-rotating rod is gap-matched with the filter residue screen cylinder; and a matching component, which is used for the counterweight block to move up and down, and cooperate with the pressure column to synchronously act on the filter residue located in the circulation plate.

[0010] Preferably, the shaking assembly also includes a sliding column fixedly connected to the slider, an elliptical groove slidingly matched with the sliding column is provided on the outer surface of the rotating rod, rolling rings are fixedly connected at both ends of the filter screen cylinder, and a rolling plate rollingly matched with the rolling ring is fixedly installed on the monitoring instrument body.

[0011] Preferably, the power part includes a motor fixedly connected to the monitor body, the output shaft of the motor is fixedly connected to a rotating plate, a cross-shaped sliding groove is provided on the rotating plate, the end of the rotating rod is hinged to two symmetrically distributed hinged plates that penetrate into the sliding groove, and the end of the hinged plate is fixedly connected to a sliding rod that slides with the sliding groove.

[0012] Preferably, the mating component includes a connecting plate, the two ends of which are respectively connected to the pressure column and the counterweight block, and the rotating rod is provided with a sliding groove that slides with the connecting plate. The pressure column and the counterweight block are pressed and fitted, and the pressure column and the counterweight block move up and down, and the debris on the movable circulating plate.

[0013] Preferably, the counterweight block is fan-shaped and has a plurality of slots formed thereon. The slots cooperate with the circulating plate, and the debris on the circulating plate is inserted through the movable slots to flexibly disperse the debris on the circulating plate.

[0014] Preferably, the inner cavity size of the monitoring instrument body is larger than the size of the filter residue screen cylinder, and the length of the chute is larger than the length of the counterweight block.

[0015] Preferably, the circulating plate is provided with evenly distributed water-permeable holes to avoid water accumulation on the circulating plate.

[0016] Preferably, the horizontal cross-sections of the slider and the movable groove are in a "+" shape that adapts to each other, so as to ensure that the slider moves up and down smoothly.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The rotating rod rotates, and under the action of the counterweight, the rotating rod drives the slider to swing up and down along the movable groove under the action of the compression spring, thereby driving the filter screen drum and the circulation plate to swing up and down. Since the circulation plate is fixed to the rotating rod, the circulation plate makes continuous circular motion in the filter screen drum, and the filter screen drum makes reciprocating rotation at a certain angle, thereby dispersing the mixed liquid and making the debris move along the circulation plate to complete the slag removal process. In this way, the activity amplitude of the slider increases the dispersion effect of the filter screen drum and the circulation plate on the debris, changes the activity trajectory of the filter screen drum, and thus improves the separation effect.

[0020] The slider moves vertically up and down along the movable groove, and the horizontal position of the slider does not change. The rotating rod rotates, and through the action of the inclined elliptical groove and the sliding column, the rotating rotating rod is made to reciprocate along the horizontal direction through the slider, thereby driving the circulation plate to move back and forth. The circulation plate reciprocates relative to the filter screen drum, changing the distance between the circulation plate and the filter screen drum, making the gap between the circulation plate and the filter screen drum larger and smaller, thereby facilitating the dispersion of the crushed slag and better entering the slag collecting drum.

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0037] Example 1

[0038] See also Figures 1-13 The present invention provides a pollution source monitor, comprising a monitor body 1 with a flow hole and a filter sieve drum 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 sieve drum 2, so that the filter sieve drum 2 can move in the inner cavity), a self-rotating rod 3 rotatably connected to the filter sieve drum 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 sieve drum 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 under the filter sieve drum 2. The wireless sensor in this application includes 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. The power supply module includes a rechargeable battery, a charging management module and a primary battery pack;

[0039] The invention also includes a shaking assembly, which causes the filter residue screen drum 2 and the circulation plate 5 to shake up and down through the self-rotating rotation rod 3 and the counterweight block 4. At the same time, the circulation plate 5 that reciprocates along the direction of the self-rotating rotation rod 3 is in clearance with the filter residue screen drum 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;

[0040] 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 fitted 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 rotating rod 3 passes through the slider 9. A limiting cylinder 11 that is rotatably connected to the filter screen cylinder 2 is fixedly connected to one of the sliders 9. A power piece is provided at the end of the rotating rod 3;

[0041] In the present application, the power member causes the self-rotating rod 3 to rotate. Under the action of the counterweight 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 screen drum 2 and the circulation plate 5 to swing up and down. Since the circulation plate 5 is fixedly connected to the self-rotating rod 3, the circulation plate 5 makes a continuous circular motion in the filter screen drum 2, thereby dispersing the solid debris and causing the debris to move along the circulation plate 5, while the liquid is removed through the through holes on the filter screen drum 2.

[0042] It is worth noting that the limiting cylinder 11 does not rotate when it moves up and down with the slider 9, so that the mixed liquid can enter the filter residue screen cylinder 2.

[0043] The shaking assembly also includes a sliding column 12 connected and fixed to the slider 9, and an elliptical groove 13 is provided on the outer surface of the rotating rod 3 to slide with the sliding column 12. Rolling rings 14 are fixedly connected to both ends of the filter residue screen drum 2, and a rolling plate 15 that rolls with the rolling ring 14 is fixedly installed on the monitoring instrument body 1. When the filter residue screen drum 2 moves up and down, the rolling ring 14 rolls along the rolling plate 15, so that the filter residue screen drum 2 moves up and down while making a reciprocating rotation at a certain angle, so that the filter residue screen drum 2 swings back and forth in the mixed liquid inside the filter residue screen drum 2, which is convenient for solid-liquid separation. Compared with the dispersion of the mixed liquid by the filter residue screen drum 2 that continuously makes a circular motion, the reciprocating rotation dispersion method is more conducive to keeping the solid and liquid away from each other, thereby increasing the separation effect;

[0044] 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 rotating rod 3 rotates. Through the action of the inclined elliptical groove 13 and the sliding column 12, the rotating rotating rod 3 is made to reciprocate along the horizontal direction through the slider 9, thereby driving the circulation plate 5 to move back and forth. The circulation plate 5 reciprocates relative to the filter screen drum 2, changing the distance between the circulation plate 5 and the filter screen drum 2, so that the gap between the circulation plate 5 and the filter screen drum 2 is sometimes larger and sometimes smaller, thereby facilitating the movement and dispersion of the crushed slag;

[0045] When the rotating rod 3 reciprocates, the hinge plate 19 rotates, and the hinge plate 19 slides along the sliding groove 18 to adjust the self-rotating rod 3 so that the self-rotating rod 3 can rotate and shake up and down while reciprocating.

[0046] The power part includes a motor 16 connected to the monitor 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 rotating rod 3 is hinged to two symmetrically distributed hinge plates 19 that penetrate into the sliding groove 18. The end of the hinge plate 19 is fixedly connected to a slide rod 20 that slides with the sliding groove 18.

[0047] 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 block 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.

[0048] The matching assembly 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. The rotation rod 3 is penetrated by a sliding groove 22 that slides with the connecting plate 21, and the pressure column 6 and the counterweight block 4 are pressed and matched;

[0049] 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 rotating rod 3 that moves up and down makes the pressure column 6 and the counterweight block 4 move synchronously, so that the pressure column 6 and the counterweight block 4 that move up and down are inserted into the debris located on the circulation plate 5 to disperse the debris.

[0050] The counterweight 4 is fan-shaped and has multiple slots 23 (the slots 23 on both sides are obliquely distributed). The slots 23 cooperate with the circulation plate 5. The mixed liquid on the circulation plate 5 is inserted through the multiple slots 23 to disperse the liquid and solid, thereby separating the solid and liquid.

[0051] 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 swing amplitude of the rotating rod 3, thereby increasing the effect of dispersing solids and liquids, and on the other hand, further disperses the moving debris on the circulating plate 5.

[0052] The inner cavity size of the monitoring instrument body 1 is larger than that of the filter sieve drum 2, and the length of the chute 22 is larger than that of the counterweight 4, so as to facilitate the movement of the filter sieve drum 2 and the counterweight 4;

[0053] 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 .

[0054] Example 2

[0055] The second embodiment is a further supplement and explanation of the first embodiment. The limiting cylinder 11 is fixedly connected to an inclined plate 24 inside, and the limiting cylinder 11 is fixedly connected to a delivery hose 25 that passes through the monitoring instrument body 1 (one end of the delivery 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 transported into the limiting cylinder 11 through the delivery 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 for separation and slag removal. 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 debris is fixedly installed below the outlet end of the filter residue screen cylinder 2, and 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;

[0056] 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 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.

[0057] The outer surface of the filter residue screen cylinder 2 is fixedly connected to a baffle 28 with an inclined distribution. The baffle 28 is located between the liquid collecting pipe 26 and the residue collecting cylinder 27 to prevent the liquid screened from 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.

[0058] The horizontal cross-sections 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.

[0059] 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 , ensuring that the counterweight 4 acts reciprocatingly in the circulating plate 5 .

[0060] Example 3

[0061] See also Figure 14 The mating 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 4. A sliding groove 22 that slides with the connecting plate 21 is provided on the rotating rod 3, and the pressure column 6 and the counterweight 4 are pressed together.

[0062] 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 further flexibly affected by the debris located on the circulating plate 5.

[0064] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
