Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of water quality monitoring and early warning, and in particular to a water quality intelligent analysis and early warning device. Background Art
[0002] Rivers are often polluted due to illegal discharge from industries along the way. Several water quality monitoring points are set up in important rivers, but current water quality monitoring generally involves sampling and then analyzing the samples to determine pollution. In order to prevent pollutants from being missed, each monitoring point must take multiple samples on the river section, increasing the workload of analysis.
[0003] Moreover, after multi-point sampling and analysis, the distribution range of pollutants in the river cannot be immediately determined. It is necessary to re-determine several sampling locations based on the sampling locations to further analyze and determine the location of the maximum pollutant concentration on the river section to assist in determining the source of pollutant emissions.
[0004] Moreover, such an early warning system cannot respond to pollution in rivers in real time. The longer the sampling and analysis cycle is, the less timely the response to pollution will be. Summary of the invention
[0005] The purpose of the present invention is to provide a water quality intelligent analysis and early warning device to solve the problems raised in the above background technology.
[0006] In order to solve the above technical problems, the present invention provides the following technical solutions:
[0007] A water quality intelligent analysis and early warning device, the early warning device comprises two early warning floats, each early warning float comprises a shell, a deformation part, and a deformation drive, the deformation parts are respectively arranged on both horizontal sides of the shell, the deformation drive is arranged in the shell, and the deformation drive changes the protrusion degree of the deformation part according to the fluid conductivity on both sides of the shell,
[0008] When looking down from the air at the warning float installed in the river, the direction of the water flow is upward:
[0009] In the early warning float located on the left, when the conductivity of the left side of the early warning float is less than that of the right side, the protrusion degree of the left deformation part of the early warning float is higher than that of the right side.
[0010] In the early warning float located on the right, when the conductivity of the left side of the early warning float is less than that of the right side, the protrusion degree of the left side deformation part of the early warning float is lower than that of the right side.
[0011] Two early warning floats are set in the river channel and float above the water surface. They can be anchored to the river bottom by pulling ropes. The early warning floats can swing left and right within the range of the ropes. The two floats are respectively provided with deformation parts. When the deformation degrees of the deformation parts on both sides of the shell are different, the flow speed of water from both sides of the shell is different, so that the shell can be affected by the force of the water flow and move horizontally perpendicular to the direction of the water flow. The deformation logic of the deformation parts of the two floats is opposite. The early warning float on the right will move to the right toward the high concentration area in the river, while the early warning float on the left will move to the left toward the river. In the low-concentration area in the river, the final staying positions of the two floats are: the float on the left stays at the left boundary of the pollution area on the river section, and the float on the right stays on the maximum concentration trace of the pollution area. The left boundary and center line of the pollution area are determined by the two floats, showing the scope of pollution. If there is no pollution in the river, the float will not displace perpendicular to the river channel, and the early warning float will remain in this position. The movement of the float is carried out in real time in the river. When there is pollution, it will cause a difference in conductivity on both sides of the float, and the float will migrate, which can provide timely early warning of water quality changes.
[0012] The deformation drive includes a permanent magnet, an electromagnet, and a resistance measuring electrode. Deformation cavities for accommodating the deformation drive are arranged on both sides of the shell. The deformation part separates the deformation cavity and the external water body.
[0013] One end of the permanent magnet pole is fixed to the deformation part, and the other end of the permanent magnet is directly facing the electromagnet. The electromagnet is energized and generates repulsion with the permanent magnet. The resistance measuring electrode is exposed outside the shell to detect the conductivity of the water body between the resistance measuring electrodes at the measuring point. During the deformation drive on the same side of the shell, the greater the conductivity measured by the resistance measuring electrode, the larger the current passed into the electromagnet.
[0014] The deformation drive on both sides of the shell uses the same voltage source.
[0015] The same voltage source powers the electromagnet. As long as there is a slight difference in the conductivity of the water on both sides of the shell, the repulsive forces of the electromagnets on the permanent magnets on both sides are different, and the deformation of the deformation parts is different, resulting in a slight difference in flow velocity on both sides. The early warning float begins to migrate perpendicular to the water flow. Most pollution sources will slightly increase the conductivity of the water. Therefore, as long as the resistance measuring electrode recognizes a slight resistance difference, a migration force will be generated, and the displacement will continue to accumulate, showing the pollution range under the long-term action of low-concentration pollutants.
[0016] The deformation part comprises a reed and a diaphragm. The diaphragm surrounds the deformation cavity along the outside of the shell. The reed is closely attached to the inner surface of the diaphragm. The permanent magnet is fixed to the reed.
[0017] The reed opens the diaphragm from the inside to prevent the permanent magnet from directly pressing against the diaphragm to deform, which would cause the deformation to be too local and fail to achieve the purpose of adjusting the lateral water flow velocity.
[0018] A water flow channel is also provided in the shell, a drainage sharp corner is provided in the water-facing section of the shell, the water flow channel is connected to the tail of the shell from the drainage sharp corner, a runner with an axis offset and perpendicular to the water flow channel is provided in the water flow channel, a rotor magnet is directly or indirectly driven by the rotating shaft of the runner, a stator coil is provided outside the rotor magnet, and the wire end position of the stator coil is used as a voltage output head, and the voltage output head is a voltage source for deformation drive.
[0019] A flow channel is constructed inside the shell to divert a stream of water into the shell. When the water in the river flows through the impeller, it pushes it to rotate. The rotating impeller drives the rotor magnet to rotate, generates an induced current in the stator coil, and outputs a voltage V at the voltage output head. This voltage V serves as the power supply in the deformation drive.
[0020] The deformation drive also includes a transistor, the base of the transistor is connected to the positive pole of the voltage output head through a resistance measuring electrode, the collector of the transistor is connected to the positive pole of the voltage output head through an electromagnet, and the emitter of the transistor is connected to the negative pole of the voltage output head.
[0021] The transistor amplifies the current on the resistance measuring electrode branch. When the resistance measuring electrode on one side senses that the water conductivity on this side is higher than that on the other side, the base current on the transistor on this side is greater than that on the other side, so that the electromagnet on the collector on this side can operate with a larger current, which is reflected in the deformation part as a larger deformation, thereby ensuring that the shell can recognize the slight difference in conductivity between the left and right sides and deform. The difference in flow rate on both sides drives the shell to move left and right.
[0022] A reverse speed transmission component is also provided between the impeller and the rotor magnet, and the reverse speed transmission component reduces the transmission ratio when the impeller speed increases.
[0023] The counter-speed transmission component arranged between the impeller and the rotor magnet is used for variable transmission ratio transmission. When the impeller speed increases, the corresponding water flow speed in the river channel becomes faster. At this time, if it is still converted to the voltage output head at an unchanged conversion rate, the deformation of the corresponding deformation part will be larger, and the water flow will push the shell in the vertical direction more. When the position of the warning float changes too quickly or violently, there will be a larger inertia force. The position change of the warning float will not be entirely due to the slight difference in the conductivity of the water on both sides of the shell, but because of some external factors. This is not expected for the position change of the warning float. Therefore, a counter-speed transmission component is added between the impeller and the rotor magnet. When the water flow velocity increases, the transmission ratio is reduced to provide a smaller voltage V for the deformation drive, thereby reducing the deformation of the deformation part. The smaller deformation of the deformation part cooperates with the water flow with increased speed, which can provide the shell with migration power perpendicular to the water flow.
[0024] The reverse speed transmission assembly includes a centrifugal swing arm, a speed matching sleeve, a transfer gear set, a rotor gear, and a central shaft. One end of the centrifugal swing arm is hinged to the end of the runner output shaft. The hinged rotation center line of the centrifugal swing arm and the runner output shaft is perpendicular to the runner output shaft. The end ball hinge of the centrifugal swing arm away from the runner is provided with an embedded rolling ball. The central shaft is colinear with the runner output shaft and fixed to the wall surface inside the shell.
[0025] There are several speed matching sleeves which are arranged concentrically. Bearings are arranged between the speed matching sleeves and they are all rotatably mounted on the central shaft. The speed matching sleeve is axially extended at one end close to the centrifugal pendulum and is provided with a fitting concave groove on the end face of the end circular ring. The speed matching sleeve is radially provided with a speed selection gear at one end away from the centrifugal pendulum. On the same speed matching sleeve: the larger the radial position of the fitting concave groove, the smaller the radius of the center circle of the speed selection gear.
[0026] The chimeric pass is located on the spherical surface of the space formed by the chimeric rolling ball movement.
[0027] The intermediate gear set is arranged beside the speed matching sleeve, and the axis of the intermediate gear set is parallel to the axis of the central shaft. The intermediate gear set has the same number of input gears and one output gear as the speed matching sleeve, and the input gears are respectively meshed with the speed selection gears. The rotor gear is fixed to one end of the rotor magnet, and the rotor gear is rotatably installed on the central shaft, and the rotor gear is meshed with the output gear.
[0028] The centrifugal pendulum rotates with the impeller. The faster the speed, the more the chimeric ball hopes to be in a larger radial position. The chimeric ball selects the chimeric gap that matches its centrifugal force and embeds it into the speed matching sleeve. If the centrifugal force becomes larger, the chimeric ball has a larger centrifugal force and passes over the chimeric gap and embeds into the chimeric gap at a larger radial position. The larger the radial position of the chimeric gap on the speed matching sleeve, the smaller the radius of the speed selection gear at the other end, and the transmission is carried out backward with a smaller transmission ratio.
[0029] An elastic member with constant elastic force is arranged between the two early warning floats.
[0030] The early warning float can identify the boundary of the pollution area. After the pollution is eliminated, the water conductivity on both sides of each early warning float is exactly the same, and the early warning float will no longer migrate. The early warning float that maintains its position can be used as a historical record of the pollution area. Of course, an elastic part can also be set to give it a reset tendency. As long as the pollution is eliminated, the two early warning floats will be pulled close together by the elastic force to promptly respond to the removal of the pollution. The elastic force of the elastic part cannot be too large and cannot cover the water pressure migration power on both sides of the shell caused by the deformation of the deformation part. The constant elastic force can be constructed using, for example, a clockwork spring. The clockwork spring is set in a warning float, and one end of the clockwork spring is pulled to connect to another early warning float.
[0031] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: the present invention detects the scope of pollutants by setting up double floats in the river channel. It does not directly detect whether the water body has reached the pollution boundary, but detects the difference in water conductivity on both sides of the warning float and amplifies it, adjusts the deformation of the deformation part, thereby obtaining a float tending to the boundary trace of the pollution area and a float tending to the center trace of the pollution area, providing monitoring personnel with early warning demarcation of the pollution range, and the early warning is carried out in real time without being limited by the sampling and analysis cycle.
[0032] The horizontal migration force of the floating body comes from the water pressure difference on both sides, which is related to the water flow velocity, and the energy supply of the internal components comes from the induced electricity caused by the flowing water pushing the impeller to rotate. Therefore, after adding the reverse speed transmission component, the increase in the impeller speed will reduce its transmission ratio to the rotor magnet and reduce the output voltage of the voltage output head, thereby reducing the deformation degree of the deformation part. Combined with the increase in water flow velocity, the horizontal migration force of the floating body is stabilized after the conductivity difference on both sides is identified.

DETAILED DESCRIPTION
[0043] 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.
[0044] See also Figure 1-Figure 8 , the present invention provides a technical solution:
[0045] A water quality intelligent analysis and early warning device, the early warning device comprises two early warning floats, each early warning float comprises a shell 1, a deformation part 2, and a deformation drive 3, the deformation parts 2 are respectively arranged on both sides of the shell 1, the deformation drive 3 is arranged in the shell 1, and the deformation drive 3 changes the protrusion degree of the deformation part 2 according to the fluid conductivity on both sides of the shell 1.
[0046] When looking down from the air at the warning float installed in the river, the direction of the water flow is upward:
[0047] In the early warning float located on the left, when the conductivity of the left side of the early warning float is less than that of the right side, the protrusion degree of the left deformation part 2 of the early warning float is higher than that of the right side.
[0048] In the early warning float located on the right, when the conductivity of the left side of the early warning float is smaller than that of the right side, the protrusion degree of the left side deformation part 2 of the early warning float is lower than that of the right side.
[0049] like Figure 1 , 2As shown, two early warning floats are set to float in the river channel and float above the water surface. They can be anchored to the river bottom by pulling ropes. The early warning floats can swing left and right within the range of the ropes. The two floats are respectively provided with deformation parts 2. When the deformation degrees of the deformation parts 2 on both sides of the shell 1 are different, the flow speed of the water from the two sides of the shell 1 is different, so that the shell 1 can be subjected to the force of the water flow and perform horizontal movement perpendicular to the direction of the water flow. The deformation logic of the deformation parts 2 of the two floats is opposite. The early warning float on the right will move to the right toward the high concentration area in the river, and the early warning float on the left will move to the left toward the low concentration area in the river. Finally, the stop positions of the two floats are: the float on the left stays at the left boundary of the pollution area on the cross section of the river, and the float on the right stays on the maximum concentration trace of the pollution area. Thus, the left boundary and center line of the pollution area are determined by the two floats, and the pollution range is displayed. If there is no pollution in the river, the float will not be displaced perpendicular to the river channel, and the early warning float will remain in this position.
[0050] The deformation driver 3 includes a permanent magnet 31, an electromagnet 32, and a resistance measuring electrode 34. The deformation chambers 12 for accommodating the deformation driver 3 are arranged on both sides of the shell 1. The deformation part 2 separates the deformation chamber 12 from the external water body.
[0051] One end of the permanent magnet 31 is fixed to the deformation part 2, and the other end of the permanent magnet 31 is directly facing the electromagnet 32. The electromagnet 32 is energized and generates repulsion with the permanent magnet 31. The resistance measuring electrode 34 is exposed outside the shell 1 to detect the conductivity of the water body between the resistance measuring electrodes 34 at the measuring point. In the deformation drive 3 on the same side of the shell 1, the larger the conductivity measured by the resistance measuring electrode 34, the larger the current passed into the electromagnet 32.
[0052] The deformation drivers 3 on both sides of the housing 1 use the same voltage source.
[0053] The same voltage source powers the electromagnet 32. As long as there is a slight difference in the conductivity of the water on both sides of the shell 1, the repulsive forces of the electromagnets 32 on the permanent magnet 31 on both sides are different, and the deformation sizes of the deformation part 2 are different, thereby forming a slight difference in flow velocity on both sides. The early warning float begins to migrate perpendicular to the water flow. Most of the pollution sources will slightly increase the conductivity of the water. Therefore, as long as the resistance measuring electrode 34 recognizes a slight resistance difference, a migration force will be generated, and the displacement will be continuously accumulated, showing the pollution range under the long-term action of low-concentration pollutants.
[0054] The deformation portion 2 includes a reed 21 and a diaphragm 22 . The diaphragm 22 surrounds the deformation cavity 12 along the outside of the housing 1 . The reed 21 is in close contact with the inner surface of the diaphragm 22 . The permanent magnet 31 is fixed to the reed 21 .
[0055] like Figure 3As shown, the reed 21 opens the diaphragm 22 from the inside to prevent the permanent magnet 31 from directly pressing against the diaphragm 22 to deform, which would cause the deformation to be too local and fail to achieve the purpose of adjusting the lateral water flow velocity.
[0056] A water flow channel 11 is also provided in the shell 1. A drainage corner is provided in the water-facing section of the shell 1. The water flow channel 11 is connected to the tail of the shell 1 from the drainage corner. A wheel 13 with an axis offset and perpendicular to the water flow channel 11 is provided in the water flow channel 11. The rotating shaft of the wheel 13 directly or indirectly drives a rotor magnet 14. A stator coil 15 is provided outside the rotor magnet 14. The wire end position of the stator coil 15 serves as a voltage output head 16, and the voltage output head 16 is the voltage source of the deformation drive 3.
[0057] like Figures 2 to 5 As shown, a flow channel is constructed in the shell 1 to guide a stream of water into the shell 1. When the water in the river flows through the impeller 13, it will push it to rotate. The rotating impeller 13 drives the rotor magnet 14 to rotate, generates an induced current in the stator coil 15, and outputs a voltage V at the voltage output head 16. This voltage V is used as the power supply in the deformation drive 3.
[0058] The deformation driver 3 also includes a transistor 33 , the base of the transistor 33 is connected to the positive pole of the voltage output head 16 through the resistance measuring electrode 34 , the collector of the transistor 33 is connected to the positive pole of the voltage output head 16 through the electromagnet 32 , and the emitter of the transistor 33 is connected to the negative pole of the voltage output head 16 .
[0059] like Figure 6 As shown, the transistor 33 amplifies the current on the branch of the resistance measuring electrode 34. When the resistance measuring electrode 34 on one side senses that the water conductivity on this side is higher than that on the other side, the base current on the transistor 33 on this side is greater than that on the other side, so that the electromagnet 32 on the collector on this side can operate with a larger current, which is reflected in the deformation part 2 as a larger deformation, thereby ensuring that the shell 1 can recognize the slight difference in conductivity between the left and right sides and deform, and the difference in flow rate on both sides drives the shell 1 to move left and right.
[0060] A reverse speed transmission assembly 4 is also provided between the rotating wheel 13 and the rotor magnet 14. The reverse speed transmission assembly 4 reduces the transmission ratio when the rotating speed of the rotating wheel 13 increases.
[0061] like Figure 7As shown, the reverse speed transmission component 4 arranged between the impeller 13 and the rotor magnet 14 is used for variable transmission ratio transmission. When the rotation speed of the impeller 13 increases, the water flow speed in the corresponding river channel becomes faster. At this time, if it is still converted to the voltage output head 16 at an unchanged conversion rate, the deformation of the corresponding deformation part 2 will be greater, and the water flow will push the shell 1 in the vertical direction more. After the position of the warning float changes too quickly or violently, there will be a larger inertial force. The position change of the warning float will not be entirely due to the slight difference in the conductivity of the water on both sides of the shell 1, but because of some external factors. This is not expected for the position change of the warning float, so a reverse speed transmission component 4 is added between the impeller 13 and the rotor magnet 14. When the water flow speed increases, the transmission ratio is reduced to provide a smaller voltage V for the deformation drive 3, so that the deformation of the deformation part 2 is reduced. The smaller deformation of the deformation part 2 cooperates with the water flow with a faster speed, which can provide the shell with migration power perpendicular to the water flow.
[0062] The reverse speed transmission assembly 4 includes a centrifugal swing rod 41, a speed matching sleeve 42, a transfer gear set 43, a rotor gear 44, and a central shaft 45. One end of the centrifugal swing rod 41 is hinged to the end of the output shaft of the runner 13. The hinged rotation center line of the centrifugal swing rod 41 and the output shaft of the runner 13 is perpendicular to the output shaft of the runner 13. The end ball hinge of the centrifugal swing rod 41 away from the runner 13 is provided with an engaging ball 411. The central shaft 45 is colinear with the output shaft of the runner 13 and is fixed to the wall surface inside the housing 1.
[0063] There are several speed matching sleeves 42 which are arranged concentrically. Bearings are set between the speed matching sleeves 42 and they are all rotatably mounted on the central shaft 45. The end of the speed matching sleeve 42 close to the centrifugal pendulum 41 extends axially and is provided with a fitting neck 421 on the end ring end surface. The end of the speed matching sleeve 42 away from the centrifugal pendulum 41 is radially provided with a speed selection gear 422. On the same speed matching sleeve 42: the larger the radial position of the fitting neck 421, the smaller the central circle radius of the speed selection gear 422.
[0064] The chimeric pass 421 is located on the spherical surface of the space formed by the movement of the chimeric rolling ball 411.
[0065] The transfer gear set 43 is arranged beside the speed matching sleeve 42, and the axis of the transfer gear set 43 is parallel to the axis of the central shaft 45. The transfer gear set 43 has the same number of input gears 431 and an output gear 432 as the speed matching sleeve 42. The input gears 431 are respectively engaged with the speed selection gears 422. The rotor gear 44 is fixed to one end of the rotor magnet 14, and the rotor gear 44 is rotatably installed on the central shaft 45. The rotor gear 44 is engaged with the output gear 432.
[0066] like Figure 7 , 8As shown, the centrifugal swing rod 41 rotates with the impeller 13. The faster the rotation speed, the more the chimeric ball 411 is expected to be in a larger radial position. The chimeric ball 411 selects the chimeric constriction 421 that matches its centrifugal force to be embedded in and then drives the speed matching sleeve 42 to rotate. If the centrifugal force becomes larger, the chimeric ball 411 has a larger centrifugal force and passes over the chimeric constriction 421 to be embedded in a chimeric constriction 421 at a larger radial position. The larger the radial position of the chimeric constriction 421 on the speed matching sleeve 42, the smaller the radius of the speed selection gear 422 at the other end thereof, and the transmission is performed backward with a smaller transmission ratio.
[0067] An elastic member with constant elastic force is arranged between the two early warning floats.
[0068] like Figure 1 As shown, the early warning float can identify the boundary of the pollution area. After the pollution is eliminated, the water conductivity on both sides of each early warning float is exactly the same, and the early warning float no longer migrates. The early warning float that maintains its position can be used as a historical record of the pollution area. Of course, an elastic member can also be provided to give it a reset tendency. As long as the pollution is eliminated, the two early warning floats will be pulled close together by the elastic force to promptly respond to the removal of the pollution. The elastic force of the elastic member cannot be too large and cannot cover the water pressure migration power on both sides of the shell 1 caused by the deformation of the deformation part 2. The constant elastic force can be constructed using, for example, a clockwork spring. The clockwork spring is provided in a warning float, and one end of the clockwork spring is pulled to connect to another early warning float.
