Description

TECHNICAL FIELD

[0001] The present application mainly relates to the technical field of water body detection, in particular to a river pollution detection equipment for ecological gardens. BACKGROUND

[0002] As an important part of urban ecological system, ecological garden river not only bears important functions such as climate regulation, water conservation and environment beautification, but also provides habitats for numerous organisms. However, with the acceleration of urbanization and the increase of human activities, ecological garden rivers are facing increasingly serious pollution problems, such as industrial wastewater discharge, direct discharge of domestic sewage, agricultural non-point source pollution, etc., which have caused great damage to the water quality and ecological environment of the river.

[0003] A garden river pollution detection system described in the prior art comprises a detection device, an analysis device, a communication device and a display device connected in sequence; the detection device comprises a water quality sensor with data acquisition function; the analysis device comprises an embedded microprocessor with data encoding and decoding and data analysis function; the communication device comprises a communication interface with line network and / or wireless network; and the display device comprises an intelligent device with water quality pollution data management control software platform.

[0004] Although the above-mentioned technology can realize real-time monitoring of pollutants, the sensor is exposed to river water containing algae, humus and silt for a long time, and impurities are easily attached to the outer surface. The accumulation of impurities will gradually interfere with the sensor signal collection, causing the detection data to deviate from the true water quality situation. When lifting through the cable, the heat is easily accumulated locally when winding the cable, and after long-term operation, the insulation performance and service life of the cable may be affected due to overheating, and even there is a hidden danger of causing safety accidents.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0030] The embodiments of the present invention will now be described.

[0031] It should be noted that the floating box 1 is moved on the garden waterway using existing technology, such as by cable or pontoon. Furthermore, a control module is installed inside the floating box 1, which can be installed near the detector 103. This module includes a wireless communication unit (such as a 4G / 5G module) and a data processing unit. One end of the module is electrically connected to the detector 103 via a wire to receive water quality test data (such as pH value, dissolved oxygen content, etc.) collected by the detector 103 in real time and remotely transmit the data to the river management backend. The other end is electrically connected to the electrical control components (such as drive motor 501, water pump 602, electromagnet 705) of the drive component 5 and water supply component 6, and can receive control commands sent by the backend to realize remote control and status monitoring of the equipment.

[0032] In this embodiment, please refer to Figures 1-8As shown, a river pollution detection device for ecological gardens includes a float box 1, a winding tube 102 penetrating both sides of the float box 1, a detection probe 105 retracted into the float box 1, and an operating mechanism. The detection probe 105 is equipped with a counterweight to prevent swaying due to water flow when submerged in the river. A strip-shaped through-slot 101 is formed on the lower surface of the float box 1. The detection probe 105 is raised and lowered via a cable 104. Both ends of the winding tube 102 penetrate the float box 1 and are rotatably connected by bearings. Baffles 1021 are fixed to both ends of the outer wall of the winding tube 102. The cable 104 is wound around the outer wall of the winding tube 102 between the two baffles 1021. A detector 103 is installed at another corner of the inner top of the float box 1. A guide rod 2 is fixed inside the float box 1 between the winding tube 102 and the detector 103. The cable 104... The two ends of 4 are connected to the detector 103 and the detector probe 105 respectively via the guide rod 2. The detector probe 105 is located above the strip channel 101. The cleaning block 4 is installed inside the float box 1 at one end of the strip channel 101. The bottom of the cleaning block 4 is provided with a storage groove 401 for storing the detector probe 105. A water storage cavity 402 is provided in the wall of the cleaning block 4. The groove wall of the storage groove 401 is evenly equipped with nozzles 403 that communicate with the water storage cavity 402. A through hole 404 communicating with the storage groove 401 is provided at the center of the top of the cleaning block 4. A through groove 405 communicating with the storage groove 401 and the through hole 404 is provided on one side of the cleaning block 4. A first pair of connecting pipes 406 is provided on the side of the cleaning block 4 near a push component 7. The insertion connecting pipe 604 matches the first pair of connecting pipes 406.

[0033] An arc-shaped sleeve plate 8 for auxiliary cooling is provided above the winding tube 102. A heat exchange chamber 803 is opened inside the arc-shaped sleeve plate 8. Several vertical conveying pipes 802 are connected to one side of the bottom wall of the arc-shaped sleeve plate 8. An L-shaped main pipe 801 is installed in the bottom of the float box 1 below the winding tube 102 through a bracket. The bottom ends of several heat exchange chambers 803 are connected to the L-shaped main pipe 801. The inlet of the L-shaped main pipe 801 is connected to the second pair of connecting pipes 8011. The insertion pipe 604 is matched with the second pair of connecting pipes 8011. A vertical return water pipe 804 is connected to the other side of the bottom wall of the arc-shaped sleeve plate 8. The bottom end of the return water pipe 804 is connected to the L-shaped water tank 106. Spring-type one-way valves are embedded in the first pair of connecting pipes 406 and the second pair of connecting pipes 8011. The valves only allow water to flow from the insertion pipe 604 to the inside of the connecting pipe. They close automatically in the opposite direction to prevent water from flowing back into the pipe when the insertion pipe 604 is removed later.

[0034] An L-shaped water tank 106 is fixed to the inner bottom of the float box 1 on the side away from the detector 103. The operating mechanism consists of a drive component 5, a water supply component 6, and a push component 7. The water supply component 6 is used to draw water from the L-shaped water tank 106 for transportation. The water supply component 6 includes a mounting block 601. A water pump 602 is installed in the inner cavity of the mounting block 601. The output end of the water pump 602 is connected to a plug pipe 604 that extends out of the cavity wall. The suction end of the water pump 602 is connected to a telescopic pipe 603. The other end of the telescopic pipe 603 extends through the wall of the L-shaped water tank 106 and into the interior. A slider 606 is installed on the lower surface of the mounting block 601 by screws. A wide slide rail 3 is installed on the inner bottom wall of the float box 1 on the side away from the winding tube 102 by screws. Narrow slide rails 301 are integrally connected to both ends of the wide slide rail 3 at the two push components 7. The sliding groove at the bottom of the slider 606 matches the wide slide rail 3. Positioning blocks 605 are fixed on both outer walls of the mounting block 601.

[0035] The drive assembly 5 is used to control the rotation of the winding tube 102 and drive the water supply assembly 6 to move laterally. There are two push assemblies 7, which are symmetrically arranged on both sides of the float box 1. The push assemblies 7 are used to push the water supply assembly 6, which has been moved into place, to move forward, so that the water supply assembly 6 is connected to the cleaning block 4 and the arc-shaped sleeve plate 8 respectively, so as to cool down the cable 104 and clean the outer surface of the detection probe 105 after it is put into the box during river pollution detection.

[0036] When conducting pollution detection on the garden's waterways, the pontoon 1 is moved to a pre-set monitoring point on the waterway via a cable or pontoon. Staff send a start signal through the management backend. Upon receiving the start signal, the control module sends start signals to the drive motor 501 of the drive assembly 5, the detector 103, and the push assembly 7 (electromagnet 705) located at the cleaning block 4. First, the electromagnet 705 of the push assembly 7 is energized, generating magnetic attraction, which moves the mounting block 601 in the water supply assembly 6 backward, causing the insertion pipe 604 to separate from the first pair of pipes 406. Then, the drive motor 501, via the main... The gear meshing of the driving wheel 502 and the driven wheel 503 drives the winding tube 102 to rotate. The cable 104 is gradually lowered under the rotation of the winding tube 102. The detection probe 105 then passes through the strip groove 101 and approaches the river surface until it is fully immersed in the preset detection depth of the river water (such as 0.5-1m, controlled by the number of rotations of the winding tube 102). The detection probe 105 collects water quality data (such as COD and ammonia nitrogen content) in the water and transmits it to the detector 103 through the cable 104. After the detector 103 performs preliminary processing on the data, it sends it to the external monitoring terminal in real time through the control module.

[0037] At the same time, the output of the drive motor 501 will also drive the lead screw 508 to rotate through the magnetic coupler 506, so that the two side push plates 509 move laterally along the slide bar 507, driving the mounting block 601 between them to move. The mounting block 601 slides into the wide slide rail 3 along the narrow slide rail 301 through the slider 606 until it moves to another narrow slide rail 301 and connects with another push component 7. Then the electromagnet 705 of the push component 7 is de-energized, and the elasticity of the return spring 702 pushes the mounting block 601 and the slider 606 forward, so that the insertion pipe 604 accurately aligns with the second pair of pipes 8011 of the arc-shaped sleeve plate 8.

[0038] Then, the water pump 602 starts, drawing clean water from the L-shaped water tank 106 into the water pump 602 through the telescopic pipe 603 (which can move and extend with the mounting block 601 to avoid pipe pulling). After being pressurized by the water pump 602, the water is delivered from the plug pipe 604 to the second pair of pipes 8011, enters the L-shaped main pipe 801, and is then delivered by several delivery pipes 802 to the heat exchange chamber 803 inside the arc-shaped sleeve plate 8. The water absorbs the heat conducted by the cable 104 on the winding tube 102 in the heat exchange chamber 803, and then flows back to the L-shaped water tank 106 through the return water pipe 804, forming a water circulation cooling system. At the same time, the external airflow passes through the winding tube 102 and forms an axial airflow along the tube cavity. It penetrates into the gap of the cable 104 through the ventilation holes opened on the winding tube 102, forming a coordinated internal and external heat dissipation with the water flow cooling of the arc-shaped sleeve plate 8.

[0039] After the test is completed, the management backend sends a recovery signal, the water pump 602 stops working, the electromagnet 705 of the corresponding push component 7 is energized and generates magnetism, controlling the mounting block 601 to move backward, canceling the connection between the insertion pipe 604 and the second pair of pipes 8011, and driving the motor 501 to rotate in the reverse direction, causing the winding tube 102 to rotate in the reverse direction, the cable 104 gradually winds around the winding tube 102, the detection probe 105 rises accordingly, and the mounting block 601 also resets and moves back to the cleaning block 4, and the electromagnet 705 in the push component 7 at that location... 05 When the power is cut off, the elasticity of the reset spring 702 pushes the mounting block 601 forward, reconnecting it to the first pair of connecting pipes 406. At this time, the detection probe 105 will be stored in the storage groove 401 of the cleaning block 4. The water pump 602 starts, and water flows through the insertion pipe 604 and the first pair of connecting pipes 406 into the water storage chamber 402 of the cleaning block 4. The water is then sprayed out through the nozzles 403 evenly distributed on the wall of the storage groove 401 to wash away algae, mud and other impurities on the outer surface of the detection probe 105. The wastewater from the washing will be discharged from the float box 1 through the strip channel 101.

[0040] Through the coordinated operation of mechanical components, the cleaning of the detection probe 105 and the cooling of the cable 104 can be completed as needed, effectively ensuring the accuracy and continuity of river pollution detection. After the detection probe 105 is retrieved to the float box 1, the water supply component 6 docks with the cleaning block 4 to rinse the impurities on the outer surface of the probe and avoid impurities interfering with the detection sensor signal. During the detection operation, the water supply component 6 moves to dock with the arc-shaped sleeve plate 8, and the water flows through the heat exchange chamber 803 to cool the cable 104 on the winding tube 102, preventing the cable 104 from having transmission problems due to high temperature.

[0041] Please see Figure 3 and Figure 6 As shown, the drive assembly 5 includes a drive motor 501 and a driven wheel 503. The driven wheel 503 is fixedly sleeved on the outer wall of the winding tube 102. The lower tooth surface of the driven wheel 503 is meshed with the driving wheel 502. The driving wheel 502 is fixedly sleeved on the output end of the drive motor 501. The inner side wall of the float box 1 is rotatably mounted with a rotating shaft 504 located below the detector 103. The outer wall of the rotating shaft 504 and the outer wall of the output end of the drive motor 501 are both fixedly sleeved with transmission wheels 505. The two transmission wheels 505 are connected by a transmission chain 5051. The end of the rotating shaft 504 is connected to the lead screw 508 via the magnetic coupler 506. Two side push plates 509 are installed on the actuating end of the lead screw 508. Both side push plates 509 are in contact with the two side walls of the mounting block 601 and are slidably connected. The drive motor 501 is fixed to the inner wall of the float box 1 by screws. A slide rod 507 is provided parallel above the lead screw 508. The two ends of the slide rod 507 are fixedly connected to the outer wall of the magnetic coupler 506 and the inner wall of the float box 1, respectively. The tops of the two side push plates 509 are fitted onto the slide rod 507 and are slidably connected.

[0042] After the drive motor 501 starts, its output end drives the drive wheel 502 and the installed transmission wheel 505 to rotate. The drive wheel 502 drives the driven wheel 503 to rotate through tooth meshing, thereby driving the winding tube 102 to rotate around its own axis, releasing (drive motor 501 rotates forward) or winding (drive motor 501 rotates in reverse) the wound cable 104. At the same time, the rotating transmission wheel 505 drives another transmission wheel 505 to rotate through the transmission chain 5051, thereby controlling the rotation of the rotating shaft 504. The power is transmitted to the lead screw 508 through the magnetic coupler 506 at the end. The rotation of the lead screw 508 causes the two side push plates 509 to move laterally along the slide bar 507. The side push plates 509 push the mounting block 601 of the water supply component 6 to move.

[0043] Please see Figure 3 , Figure 5 , Figure 7 and Figure 8As shown, both pushing components 7 include a telescopic rod 701, which is fixedly connected to the inner wall of the float box 1 by screws. A push block 703 is connected to the telescopic end of the telescopic rod 701 by screws. A return spring 702 is sleeved on the outside of the telescopic rod 701. The two ends of the return spring 702 are fixedly connected to the outer wall of the push block 703 and the inner wall of the float box 1, respectively. An annular iron plate 704 and an electromagnet 705 are fixed to the outer wall of the push block 703 and the inner wall of the float box 1, respectively, outside the return spring 702. The push block 703 is magnetically connected to the iron sheet 704. A loop-shaped positioning plate 7031 is fixed on the outer wall of the push block 703 away from the telescopic rod 701. The positioning block 605 in the water supply component 6 matches the loop-shaped positioning plate 7031. A pressure sensor is also embedded in the surface of the loop-shaped positioning plate 7031 to monitor the contact between the installation block 601 and the loop-shaped positioning plate 7031. Several balls are embedded in the lower surface of the push block 703, which roll in contact with the bottom wall of the float box 1. The balls can reduce friction and ensure movement efficiency.

[0044] Before the drive motor 501 starts, the electromagnet 705 is energized to generate magnetism, attracting the iron plate 704 on the outer wall of the push block 703, causing the push block 703 to move backward against the elastic force of the return spring 702. The U-shaped positioning plate 7031 on the push block 703 drives the mounting block 601 to move synchronously through the inserted positioning block 605. The mounting block 601 drives the slider 606 and the insertion pipe 604 to move, so that the insertion pipe 604 is separated from the connected connecting pipe. Then, the movement of the two side push plates 509 drives the mounting block 601 to move, so that the slider 606 moves from the narrow slide rail 301 to the wide slide rail 3 and moves to the other side of the float box 1.

[0045] The working principle of this invention is as follows:

[0046] When conducting pollution detection on the garden's waterways, the pontoon 1 is moved to the preset monitoring point on the waterway via a cable or pontoon. Staff send a start signal through the management backend. After receiving the start signal, the control module sends start signals to the drive motor 501 of the drive component 5, the detector 103, and the push component 7 (electromagnet 705) located at the cleaning block 4. First, the electromagnet 705 of the push component 7 is energized, generating a magnetic attraction force that attracts the iron plate 704 on the outer wall of the push block 703, causing the push block 703 to move backward against the elastic force of the return spring 702. The U-shaped positioning plate 7031 on the push block 703 drives the mounting block 601 to move synchronously through the inserted positioning block 605. The mounting block 601 moves between the two side push plates 509, and drives the slider 606 and the insertion pipe 604 to move, causing the insertion pipe 604 to separate from the connected connecting pipe.

[0047] Next, the drive motor 501 starts (rotates forward), and its output drives the drive wheel 502 and the installed transmission wheel 505 to rotate. The drive wheel 502 drives the driven wheel 503 to rotate through tooth meshing, which in turn drives the winding tube 102 to rotate around its own axis, releasing the wound cable 104. The detection probe 105 then passes through the strip groove 101 and approaches the river surface until it is completely immersed in the preset detection depth of the river water. The detection probe 105 collects water quality data in the water and transmits it to the detector 103 through the cable 104. After the detector 103 performs preliminary processing on the data, it sends it to the external monitoring terminal in real time through the control module.

[0048] Meanwhile, the rotating transmission wheel 505 drives another transmission wheel 505 to rotate through the transmission chain 5051, thereby controlling the rotation of the rotating shaft 504. The power is transmitted to the lead screw 508 through the magnetic coupler 506 at the end. The rotation of the lead screw 508 causes the two side push plates 509 to move laterally along the slide bar 507. The side push plates 509 push the mounting block 601 to move, causing the slider 606 to slide along the narrow slide rail 301 into the wide slide rail 3 until it moves to another narrow slide rail 301. The positioning block 605 of the mounting block 601 is inserted into the loop positioning plate 7031 in another push assembly 7. After the pressure sensor detects the pressure, it sends a signal to the control module to de-energize the electromagnet 705 of the push assembly 7. The elasticity of the return spring 702 pushes the mounting block 601 and the slider 606 forward, so that the insertion pipe 604 accurately aligns with the second pair of pipes 8011 of the arc-shaped sleeve plate 8.

[0049] Then, the water pump 602 starts, drawing clean water from the L-shaped water tank 106 into the water pump 602 through the telescopic pipe 603. After being pressurized by the water pump 602, the water is transported from the plug pipe 604 to the second pair of pipes 8011, enters the L-shaped main pipe 801, and is then transported by several delivery pipes 802 to the heat exchange chamber 803 inside the arc-shaped sleeve plate 8. The water absorbs the heat conducted by the cable 104 on the winding tube 102 in the heat exchange chamber 803, and then flows back to the L-shaped water tank 106 through the return water pipe 804, forming a water circulation cooling system. At the same time, the external airflow passes through the winding tube 102 and forms an axial airflow along the tube cavity. It penetrates into the gap of the cable 104 through the ventilation holes opened on the winding tube 102, forming a coordinated internal and external heat dissipation with the water flow cooling of the arc-shaped sleeve plate 8.

[0050] After the test is completed, the management backend sends a recovery signal, the water pump 602 stops working, and the electromagnet 705 of the corresponding drive component 7 is energized to generate magnetism, controlling the mounting block 601 to move backward, canceling the connection between the insertion pipe 604 and the second pair of pipes 8011, and driving the motor 501 to rotate in the reverse direction, causing the winding tube 102 to rotate in the reverse direction, and the cable 104 gradually winds around the winding tube 102. The detection probe 105 rises accordingly, and the mounting block 601 also resets and moves back to the cleaning block 4, where the electromagnet 705 in the drive component 7 is activated. 5. When the power is cut off, the elasticity of the reset spring 702 pushes the mounting block 601 forward, reconnecting it to the first pair of connecting pipes 406. At this time, the detection probe 105 will be stored in the storage groove 401 of the cleaning block 4. The water pump 602 starts, and water flows through the insertion pipe 604 and the first pair of connecting pipes 406 into the water storage chamber 402 of the cleaning block 4. The water is then sprayed out through the nozzles 403 evenly distributed on the wall of the storage groove 401 to wash away algae, mud and other impurities on the outer surface of the detection probe 105. The wastewater from the washing will be discharged from the float box 1 through the strip channel 101.
