Description

Technical Field

[0001] The present invention relates to the technical field of monitoring devices, and more specifically, to an environmental monitoring device for preventing and controlling surface water pollution. Background Art

[0002] Surface water refers to the general term for dynamic water and static water on the land surface, mainly including rivers, lakes, swamps, glaciers, ice sheets, etc. It is one of the important sources of water for human life and a major component of water resources in various countries. In order to understand the water quality of surface water, it is necessary to monitor surface water regularly.

[0003] Existing monitoring devices can only monitor water quality at a specified depth. Since the water quality components in the water body are unevenly distributed in space and time due to factors such as river flow, temperature, and depth, and certain substances in the water body will precipitate or stratify due to factors such as density and particle size, the reliability of the monitoring results is low.

[0004] In view of the above problems, some solutions are also provided in the prior art. For example, Chinese invention patent with publication number CN117554582B discloses a water quality monitoring device and monitoring method for water pollution prevention and control. The device is provided with a lifting component, and the lifting component is used to drive the adjusting rod to move up and down, so that the sampling tube is lowered to the corresponding depth. After the water pump is started to pump water into the monitoring box through the hose, the water quality sensor is used to detect the water sample in the monitoring box, thereby improving the reliability of the monitoring data. Although the prior art can improve the reliability of the monitoring data by monitoring the water quality at different depths, the prior art needs to detect the water quality multiple times, and the water quality data of a single depth cannot reflect the comprehensive water quality of the entire water area. Summary of the invention

[0005] In view of the problems existing in the prior art, the purpose of the present invention is to provide an environmental monitoring device for surface water pollution prevention and control, which can reflect the comprehensive water quality of the entire water area without multiple monitoring, thereby improving data reliability and convenience of monitoring.

[0006] To solve the above problems, the present invention adopts the following technical solutions.

[0007] An environmental monitoring device for surface water pollution prevention and control, comprising a mounting plate, a monitoring box is fixedly mounted on the top wall of the mounting plate, and a monitor for monitoring water quality is provided on the monitoring box;

[0008] It also includes a water intake component, which includes a reciprocating screw rotatably mounted on a mounting plate, an impeller fixedly mounted on the bottom end of the reciprocating screw, a disc threadedly mounted on the reciprocating screw, a telescopic tube fixedly mounted between the top wall of the disc and the bottom wall of the mounting plate, an air intake valve whose input end is connected to the outside is fixedly mounted on the mounting plate, a first air pipe connected to a monitoring box is inserted on the input end of the air intake valve, a first water pipe for supplying water to the monitoring box is provided on the bottom wall of the disc, and a water discharge component cooperating with the monitoring box is provided on the mounting plate.

[0009] Furthermore, the drain assembly includes a horizontal groove provided on the mounting plate, a horizontal rod is slidably installed in the horizontal groove, a first spring is fixedly installed between the horizontal rod and the horizontal groove, a magnet block is embedded in the horizontal rod, a coil electrically connected to the monitor is embedded in the mounting plate, a drain hole is provided on the monitoring box, a sealing plate which cooperates with the drain hole is vertically slidably installed on the mounting plate, a second spring is fixedly installed between the sealing plate and the mounting plate, and the end of the horizontal rod close to the sealing plate is an inclined surface, and a control assembly which cooperates with the mounting plate is provided on the horizontal rod.

[0010] Furthermore, the control component includes a slide groove opened on the horizontal rod, a fixed rod is slidably installed in the slide groove, a third spring is fixedly installed between the fixed rod and the slide groove, a vertical groove connected to the telescopic tube is opened on the bottom wall of the slide groove, a limiting rod cooperating with the vertical groove is fixedly installed on the disc, a fixing groove cooperating with the fixing rod is opened on the limiting rod, and the end of the fixing rod close to the limiting rod is an inclined surface.

[0011] Furthermore, an L-shaped mixing rod is fixedly installed at one end of the reciprocating screw in the monitoring box, a mixing chamber is provided on the mixing rod, mixing holes are evenly provided on the mixing chamber, an annular cavity connected to the first water pipe is provided on the mounting plate, and a connecting pipe connected to the annular cavity is inserted on the mixing chamber.

[0012] Furthermore, a filter cover for filtering solid particles is provided on the bottom wall of the disc, a telescopic rod extending to the bottom wall of the filter cover is rotatably mounted on the mounting plate, a scraper fitted with the outer wall of the filter cover is fixedly mounted on the telescopic rod, a first gear is fixedly mounted on the telescopic rod, and a second gear meshing with the first gear is fixedly mounted on the reciprocating screw.

[0013] Furthermore, an air supply rod that fits with the inner wall of the filter cover is fixedly installed on the telescopic rod, an air groove is opened on the air supply rod, a second air pipe is inserted in the air groove, and an exhaust valve connected to the input end and the telescopic tube is fixedly installed at one end of the second air pipe away from the air groove.

[0014] Furthermore, vertical rods are symmetrically fixedly mounted on the bottom wall of the mounting plate.

[0015] Furthermore, a solar panel for supplying power to the monitor is provided on the top wall of the monitoring box, and an indicator light electrically connected to the monitor is provided on the monitoring box.

[0016] Furthermore, the top wall of the limiting rod is an inclined surface.

[0017] Furthermore, the side wall of the drain hole forms an angle of seventy-five degrees with the vertical plane.

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

[0019] (1) This scheme sets a telescopic tube. When the water flows through the impeller and drives the reciprocating screw to rotate, the reciprocating screw drives the first water pipe to move downward through the disc and stretches the telescopic tube. Then the telescopic tube drives the monitoring box to absorb water through the first water pipe. Due to the movement of the first water pipe, the monitoring box can absorb water flows at different depths, thereby effectively preventing the stratification of certain substances in the water flow from affecting the reliability of the monitoring results, thereby improving the accuracy of the data.

[0020] (2) This scheme sets a horizontal rod. After the monitoring is completed and the monitor is powered off, the first spring drives the horizontal rod to disengage from the sealing plate. At this time, the second spring drives the sealing plate to disengage from the drain hole. Then the water in the monitoring box can flow to the outside through the drain hole. That is, the water in the monitoring box can be released immediately after the monitoring is completed. This can prevent the water from staying in the monitoring box for too long, causing impurities in the water to adhere to the monitoring box and affect the accuracy of the next monitoring data, thereby further improving the accuracy of the monitoring data.

[0021] (3) In this scheme, by setting a mixing rod, the water flow entering the monitoring box will first pass through the mixing hole on the mixing chamber and then enter the monitoring box, so that the water flow in the monitoring box can be evenly mixed, and the mixing rod can be driven to rotate during the rotation of the reciprocating screw. During the rotation of the mixing rod, the water flow in the monitoring box can be stirred, which further improves the mixing effect of the water flow, thereby improving the accuracy of the monitoring data. Then, when the water flows to the outside through the drain hole, the rotating mixing rod can clean the inner wall of the monitoring box, thereby preventing the inner wall of the monitoring box from remaining stains and affecting the accuracy of the next monitoring data, thereby further improving the accuracy of the monitoring data.

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0032] See also Figures 1 to 7 , an environmental monitoring device for surface water pollution prevention and control, comprising a mounting plate 1, a monitoring box 2 is fixedly mounted on the top wall of the mounting plate 1, and a monitor 3 for monitoring water quality is provided on the monitoring box 2;

[0033] It also includes a water intake component, which includes a reciprocating screw 401 rotatably mounted on the mounting plate 1, an impeller 402 fixedly mounted on the bottom end of the reciprocating screw 401, a disc 403 threadedly mounted on the reciprocating screw 401, a telescopic tube 404 fixedly mounted between the top wall of the disc 403 and the bottom wall of the mounting plate 1, an air intake valve 405 whose input end is connected to the outside is fixedly mounted on the mounting plate 1, a first air pipe 406 connected to the monitoring box 2 is inserted on the input end of the air intake valve 405, a first water pipe 407 for supplying water to the monitoring box 2 is provided on the bottom wall of the disc 403, and a water discharge component cooperating with the monitoring box 2 is provided on the mounting plate 1.

[0034] The water discharge component includes a horizontal groove provided on the mounting plate 1, a horizontal rod 501 is slidably installed in the horizontal groove, a first spring 502 is fixedly installed between the horizontal rod 501 and the horizontal groove, a magnet block 503 is embedded in the horizontal rod 501, a coil 504 electrically connected to the monitor 3 is embedded in the mounting plate 1, a water discharge hole 505 is provided on the monitoring box 2, a sealing plate 506 cooperating with the water discharge hole 505 is vertically slidably installed on the mounting plate 1, a second spring 507 is fixedly installed between the sealing plate 506 and the mounting plate 1, and the end of the horizontal rod 501 close to the sealing plate 506 is an inclined surface, and a control component cooperating with the mounting plate 1 is provided on the horizontal rod 501.

[0035] The control assembly includes a slide groove provided on the horizontal rod 501, a fixed rod 601 is slidably installed in the slide groove, a third spring 602 is fixedly installed between the fixed rod 601 and the slide groove, a vertical groove 603 connected to the telescopic tube 404 is provided on the bottom wall of the slide groove, a limiting rod 604 cooperating with the vertical groove 603 is fixedly installed on the disc 403, a fixing groove 605 cooperating with the fixing rod 601 is provided on the limiting rod 604, and the end of the fixing rod 601 close to the limiting rod 604 is an inclined surface.

[0036] When in use, the mounting plate 1 is placed in a flowing water area such as a river, and then the water flow will hit the impeller 402 and drive the impeller 402 to rotate. During the rotation of the impeller 402, the reciprocating screw rod 401 is driven to rotate. Since the disc 403 is fixedly connected to the mounting plate 1 through the telescopic tube 404, the disc 403 cannot rotate. Then, during the rotation of the reciprocating screw rod 401, the disc 403 is driven to move downward and stretch the telescopic tube 404. Then, during the downward movement of the disc 403, the first water pipe 407 is driven to move downward. At the same time, during the stretching of the telescopic tube 404, the telescopic tube 404 is pulled downward. 04 decreases, and air is sucked from the monitoring box 2 through the air inlet valve 405 and the first air pipe 406. Then the pressure in the monitoring box 2 decreases. Under the action of pressure, the monitoring box 2 draws water from the bottom wall of the disc 403 through the first water pipe 407, so that the monitoring box 2 can absorb water at different depths. Then, as the water level in the monitoring box 2 rises, the water gradually contacts the monitor 3. At this time, the monitor 3 can analyze the water quality of the water, thereby effectively preventing the stratification of certain substances in the water from affecting the reliability of the monitoring results, thereby improving the accuracy of the data.

[0037] In the initial state, the first spring 502 and the second spring 507 are both in a free extension state, and then the monitor 3 can be set to start automatically at a fixed time, so that the monitor 3 is regularly turned on to monitor the water flow. When the monitor 3 is started, the coil 504 is energized and generates a magnetic field. Then, under the action of the magnetic field, the magnet block 503 drives the horizontal rod 501 to move toward the direction of the coil 504. During the movement of the horizontal rod 501, the inclined surface of the horizontal rod 501 gradually contacts the sealing plate 506 and applies an upward thrust to the sealing plate 506. At this time, the first spring 502 is stretched and has a tendency to recover. Then, under the action of the thrust, the sealing plate 506 moves upward and blocks the drain hole 505. At this time, the second spring 507 is compressed and has a tendency to recover. The original trend is that when the monitoring is completed, the monitor 3 is automatically powered off, and the coil 504 is powered off at this time, and then the magnetic field of the coil 504 disappears, and then the first spring 502 contracts and drives the horizontal rod 501 to reset. During the resetting process of the horizontal rod 501, it gradually loses contact with the sealing plate 506. At this time, the second spring 507 extends and drives the sealing plate 506 to lose contact with the drain hole 505. At this time, the water flow in the monitoring box 2 can flow to the outside through the drain hole 505, that is, the water flow in the monitoring box 2 can be released immediately after the monitoring is completed, thereby avoiding the water flow staying in the monitoring box 2 for too long, causing impurities in the water flow to adhere to the monitoring box 2, and affecting the accuracy of the next monitoring data, thereby further improving the accuracy of the monitoring data.

[0038] When the coil 504 drives the horizontal rod 501 to move through the magnet, the horizontal rod 501 drives the fixed rod 601 to disengage from the fixed groove 605. That is, at this time, the impeller 402 can drive the limit rod 604 to move downward through the reciprocating screw rod 401 and the disc 403. When the monitor 3 is turned off, the first spring 502 drives the horizontal rod 501 to reset. When the disc 403 moves to the lowest point, the reciprocating screw rod 401 drives the disc 403 to move upward. In the process of the disc 403 moving upward, it drives the limit rod 604 to move upward. In the process of the limit rod 604 moving upward, it gradually inserts into the vertical groove 603 and contacts the inclined surface of the fixed rod 601. Then the limit rod 604 pushes the fixed rod 601 through the inclined surface The fixed rod 601 moves along the slide groove and squeezes the third spring 602. When the fixed rod 601 contacts the fixed groove 605, the third spring 602 stretches and drives the fixed rod 601 to insert into the fixed groove 605. Then, under the action of the fixed rod 601, the limit rod 604 is fixed and cannot move downward, that is, the disc 403 cannot move downward at this time, and the disc 403 is threadedly matched with the reciprocating screw 401, that is, the reciprocating screw 401 and the impeller 402 cannot rotate at this time, and then when no monitoring is needed, the water flow can be automatically stopped from being collected, thereby reducing the wear of the impeller 402 and the reciprocating screw 401, and at the same time, it can also prevent the water flow from repeatedly and frequently entering the monitoring box 2, resulting in residual impurities in the monitoring box 2 affecting the reliability of the data.

[0039] like Figure 3 , Figure 4 , Figure 6 As shown, the reciprocating screw rod 401 is fixedly installed with an L-shaped mixing rod 701 at one end of the monitoring box 2, the mixing rod 701 is provided with a mixing chamber 702, the mixing chamber 702 is evenly provided with mixing holes 703, the mounting plate 1 is provided with an annular chamber 704 connected with the first water pipe 407, and the mixing chamber 702 is provided with a connecting pipe 705 connected with the annular chamber 704.

[0040] By adopting the above technical solution, when the monitoring box 2 absorbs water through the first water pipe 407, the water flows into the mixing chamber 702 through the first water pipe 407, the annular chamber 704, and the connecting pipe 705, and flows evenly into the monitoring box 2 through the mixing hole 703 on the mixing chamber 702, so that the water in the monitoring box 2 can be evenly mixed, and the mixing rod 701 can be driven to rotate during the rotation of the reciprocating screw 401. During the rotation of the mixing rod 701, the water in the monitoring box 2 can be stirred, which further improves the mixing effect of the water flow, thereby improving the accuracy of the monitoring data, and then the rotating mixing rod 701 can clean the inner wall of the monitoring box 2 when the water flows to the outside through the drain hole 505, thereby preventing the inner wall of the monitoring box 2 from residual stains and affecting the accuracy of the next monitoring data, thereby further improving the accuracy of the monitoring data.

[0041] like Figure 3 , Figure 6 As shown, a filter cover 801 for filtering solid particles is provided on the bottom wall of the disc 403, a telescopic rod 802 extending to the bottom wall of the filter cover 801 is rotatably mounted on the mounting plate 1, a scraper 803 fitted to the outer wall of the filter cover 801 is fixedly mounted on the telescopic rod 802, a first gear 804 is fixedly mounted on the telescopic rod 802, and a second gear 805 meshing with the first gear 804 is fixedly mounted on the reciprocating screw 401.

[0042] An air supply rod 901 that fits the inner wall of the filter cover 801 is fixedly installed on the telescopic rod 802, an air groove 902 is opened on the air supply rod 901, a second air pipe 903 is inserted in the air groove 902, and an exhaust valve 904 that is connected to the input end and the telescopic tube 404 is fixedly installed on the end of the second air pipe 903 away from the air groove 902.

[0043] By adopting the above-mentioned technical scheme, during the process of the monitoring box 2 absorbing water through the first water pipe 407, the filter cover 801 can be set to filter the water flowing to the first water pipe 407, thereby effectively preventing water plants or large particles of dirt from entering the monitoring box 2 and affecting the accuracy of the monitoring data. During the rotation of the reciprocating screw 401, the first gear 804 is driven to rotate by the second gear 805, and then the scraper 803 is driven to rotate by the telescopic rod 802 during the rotation of the first gear 804. During the rotation of the scraper 803, the particles on the surface of the filter cover 801 can be cleaned, thereby effectively preventing the particles from clogging the filter cover 801, resulting in the monitoring box 2 being unable to evenly absorb water flows of different depths, thereby affecting the reliability of the monitoring data.

[0044] In the process of water flowing through the filter cover 801 to the first water pipe 407, it is inevitable that some impurities will be mixed in the gaps of the filter cover 801. Then, in the process of the threaded rod driving the disc 403 to move upward, the rotating telescopic rod 802 drives the air groove 902 to rotate through the air supply rod 901. Then, in the process of the disc 403 moving upward, the gas in the telescopic tube 404 is squeezed, and flows to the air groove 902 through the exhaust valve 904 and the second air pipe 903, and is blown to the gap of the filter cover 801 through the air groove 902. In the process of the air flow passing through the gap of the filter cover 801, the impurities in the gap of the filter cover 801 can be driven to break away from the filter cover 801, thereby further improving the cleaning effect of the filter cover 801.

[0045] like Figure 1 As shown, vertical rods 10 are symmetrically fixedly mounted on the bottom wall of the mounting plate 1 .

[0046] By adopting the above technical solution, before monitoring, the vertical rod 10 can be inserted into the bottom soil, and then the monitoring device is fixed under the action of the vertical rod 10, thereby preventing the monitor 3 from shaking through the mounting plate 1 and the monitoring box 2 and affecting the accuracy of the monitoring data.

[0047] like Figure 2 As shown, a solar panel 11 for supplying power to the monitor 3 is disposed on the top wall of the monitoring box 2 , and an indicator light 12 electrically connected to the monitor 3 is disposed on the monitoring box 2 .

[0048] By adopting the above technical solution, since the monitoring device is generally located outdoors, it is difficult to power the monitoring device. By setting up the solar panel 11, electricity can be stored for the monitoring device, thereby facilitating the monitoring device to monitor the water quality; when the monitoring is completed, if the water quality is unqualified, the monitor 3 will transmit a signal to the indicator light 12, and then the indicator light 12 will emit a red light, and remind nearby residents and monitoring personnel that there is a problem with the water quality.

[0049] like Figure 7 As shown, the top wall of the limiting rod 604 is an inclined surface.

[0050] By adopting the above technical solution, during the process of inserting the limiting rod 604 into the vertical groove 603 , by making the top wall of the limiting rod 604 an inclined surface, the initial contact area between the limiting rod 604 and the vertical groove 603 can be reduced, thereby facilitating the limiting rod 604 to be inserted into the vertical groove 603 .

[0051] like Figure 5 As shown, the side wall of the drain hole 505 forms an angle of seventy-five degrees with the vertical plane.

[0052] By adopting the above technical solution, by making the side wall of the drain hole 505 form a sixty-degree angle with the vertical plane, the possibility of airflow driving impurities into the monitoring box 2 when windy can be reduced, thereby reducing the impact of external factors on the monitoring data.

[0053] Instructions for use: When in use, place the mounting plate 1 in flowing waters such as rivers, and then the water flow will hit the impeller 402 and drive the impeller 402 to rotate, and during the rotation of the impeller 402, the reciprocating screw rod 401 will be driven to rotate. Since the disc 403 is fixedly connected to the mounting plate 1 through the telescopic tube 404, the disc 403 cannot rotate. Then, during the rotation of the reciprocating screw rod 401, the disc 403 is driven to move downward and stretch the telescopic tube 404. Then, during the downward movement of the disc 403, the first water pipe 407 is driven to move downward. At the same time, during the stretching of the telescopic tube 404, the pressure in the telescopic tube 404 is reduced, and air is sucked from the monitoring box 2 through the air inlet valve 405 and the first air pipe 406. Then, the pressure in the monitoring box 2 is increased. Lowered, under the action of pressure, the monitoring box 2 draws water from the bottom wall of the disc 403 through the first water pipe 407, so that the monitoring box 2 can draw water at different depths, and then as the water level in the monitoring box 2 rises, the water gradually contacts the monitor 3, and at this time the monitor 3 can analyze the water quality of the water; when the monitor 3 is started, the coil 504 is energized and generates a magnetic field, and then under the action of the magnetic field, the magnet block 503 drives the horizontal rod 501 to move toward the coil 504, and in the process of the horizontal rod 501 moving, the inclined surface of the horizontal rod 501 gradually contacts the sealing plate 506 and applies an upward thrust to the sealing plate 506, and at this time the first spring 502 is stretched and has a tendency to recover, and then under the action of the thrust The lower sealing plate 506 moves upward and blocks the drain hole 505. At this time, the second spring 507 is compressed and has a tendency to recover. When the monitoring is completed, the monitor 3 is automatically powered off. At this time, the coil 504 is powered off, and then the magnetic field of the coil 504 disappears. Then the first spring 502 contracts and drives the horizontal rod 501 to reset. During the reset process of the horizontal rod 501, it gradually loses contact with the sealing plate 506. At this time, the second spring 507 stretches and drives the sealing plate 506 to lose contact with the drain hole 505. At this time, the water in the monitoring box 2 can flow to the outside through the drain hole 505, that is, the water in the monitoring box 2 can be released immediately after the monitoring is completed, thereby preventing the water from staying in the monitoring box 2 for too long and causing impurities in the water flow The substance is attached to the monitoring box 2; when the monitoring box 2 absorbs water through the first water pipe 407, the water flows into the mixing chamber 702 through the first water pipe 407, the annular cavity 704, and the connecting pipe 705, and flows evenly into the monitoring box 2 through the mixing hole 703 on the mixing chamber 702, so that the water in the monitoring box 2 can be evenly mixed, and then the mixing rod 701 can be driven to rotate during the rotation of the reciprocating screw 401. During the rotation of the mixing rod 701, the water in the monitoring box 2 can be stirred, which further improves the mixing effect of the water flow, thereby improving the accuracy of the monitoring data, and the rotating mixing rod 701 can clean the inner wall of the monitoring box 2 during the process of the water flowing to the outside through the drain hole 505.

[0054] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
