Description

Technical Field

[0001] The present invention relates to the technical field of water quality monitoring, and in particular to a water quality monitoring device and a monitoring method thereof. Background Art

[0002] Water quality monitoring mainly monitors the quality of water areas and is used to reflect comprehensive indicators of water quality conditions. Generally, water samples such as temperature, color, turbidity, pH value, conductivity, suspended solids, dissolved oxygen, chemical oxygen demand and biochemical oxygen demand are collected for comprehensive judgment. When monitoring a large area of water, the water quality conditions at different locations will be different, so it is necessary to monitor different locations of the water area and conduct a comprehensive evaluation.

[0003] Chinese patent application number CN221802970U discloses a cruise-type water quality monitoring station, comprising a floating platform, below which are arranged an equipment layer, a counterweight layer, and a drive layer. The equipment layer houses an automatic cable reel with a cable wound around it. The cable runs through the bottom wall of the equipment layer and is connected to a first sensor. A counterweight is provided at the lower end of the first sensor. The drive layer houses a drive mechanism. The drive layer drives the entire monitoring station to different locations within the water. When collecting data, the automatic cable reel is controlled to rotate, paying out the cable, causing the first sensor at the end of the cable to descend.

[0004] The shortcomings of the above-mentioned existing technical solutions are: although the above-mentioned solution can be moved in the water area and monitor the water quality at different positions by retracting and extending the cable, the first sensor for collecting water quality data is not effectively cleaned each time after the first sensor is retracted by reeling in the cable. After the sensor contacts the water source, especially in the presence of polluted water, impurities and pollutants in the water are easily attached to the surface of the sensor probe. When the position is changed for monitoring, the accuracy and reliability of the monitoring results will be greatly affected. Moreover, the sensor is directly sunk into the water for monitoring, and is easily damaged by floating objects. Summary of the Invention

[0018] A monitoring method for a water quality monitoring device, the specific steps are as follows:

[0023] Beneficial effects of the present invention:

[0024] 1. The water quality monitoring device adopted in the present invention can float on the water surface by means of a buoyancy mechanism and be driven by a driving paddle to move in the water area, so as to facilitate monitoring the water quality at different positions and monitor a variety of water quality data by means of a multi-parameter sensor group. During each monitoring, the installation tube installed with the multi-parameter sensor group is first lowered and immersed in the water. After the monitoring is completed, the installation tube is controlled to rise. During the rising process of the installation tube, the swing tube arranged at the bottom thereof relies on the one-way movable baffles arranged on both sides to alternately squeeze the fixed baffles longitudinally staggered on both sides to realize the reciprocating swing of the swing tube. The swinging swing tube relies on a linkage mechanism to rotate the top plate to squeeze the piston block in the piston liquid feeding tube, so that the cleaning liquid is flushed to the multi-parameter sensor group through the nozzle. At the same time, the soft brush is also linked to move up and down to wipe the sensor to achieve cleaning, thereby reducing the impact on the accuracy of the next water quality data collection.

[0025] 2. The swing cylinder of the present invention swings as the mounting cylinder rises, and the swinging facilitates the removal of attachments attached to the filter element, thereby avoiding blockage and affecting subsequent monitoring. It also facilitates the accelerated discharge of water entering the mounting cylinder and the swing cylinder. At the same time, the swing cylinder also links the elastic metal frame to drive the impact ball to impact the mounting cylinder made of elastic metal, causing it to vibrate and transmit it to the sensor, thereby shaking off the attachments and improving the cleaning effect.

[0026] 3. The present invention relies on the combination of the mounting cylinder, the swing cylinder and the filter element to protect the multi-parameter sensor group, preventing the multi-parameter sensor group from colliding with floating objects and causing damage during the movement of the device in the water, thereby affecting its use.

DETAILED DESCRIPTION

[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 any creative efforts shall fall within the scope of protection of the present invention.

[0037] like Figure 1-Figure 7As shown, a water quality monitoring device can be remotely controlled and moved on the water surface, which is convenient for water quality monitoring at different locations of a wide range of water sources. It includes a support plate 1, a buoyancy mechanism and a drive paddle 6. The buoyancy mechanism is arranged below the support plate 1. The buoyancy mechanism is used to float on the water surface, thereby supporting the support plate 1. The drive paddle 6 is installed on one side of the buoyancy mechanism. The drive paddle 6 includes a steering drive motor and a propulsion drive motor. The propulsion drive motor is used to drive the paddle 6 to rotate and generate propulsion force. The two are integrated. The steering drive motor is used to adjust the angle of the integrated propulsion drive motor and the drive paddle 6, thereby adjusting the monitoring device to turn on the water surface; the device also includes a multi-parameter lifting water quality monitoring mechanism and a self-cleaning mechanism. The multi-parameter lifting water quality monitoring mechanism includes a multi-parameter sensor group 22 and a swinging filtering mechanism for protecting the multi-parameter sensor group 22. The multi-parameter sensor group 22 includes a pH value acquisition The multi-parameter sensor group 22 is provided with a data processing unit 5, which is used to collect and store different data collected by the multi-parameter sensor group 22, and can be remotely transmitted to the control terminal. At the same time, the data processing unit 5 also includes a remote instruction receiving module and a control module, which is convenient for receiving the control instructions sent by the terminal, and then controlling the driving paddle 6 to drive the operation. At the same time, it can also control the multi-parameter lifting water quality monitoring mechanism to lift and lower, which is convenient for water quality monitoring; relying on the swinging filter mechanism to filter larger garbage and debris in the water to prevent the multi-parameter sensor group 22 from being damaged by impact; in the process of the multi-parameter lifting water quality monitoring mechanism rising, the swinging filter mechanism swings back and forth to facilitate the removal of attached garbage and debris;

[0038] The self-cleaning mechanism includes a flushing mechanism and a linkage mechanism. The flushing mechanism is used to flush and clean the multi-parameter sensor group 22. The linkage mechanism is arranged between the flushing mechanism and the swinging filter mechanism. During the reciprocating swinging process of the swinging filter mechanism, the linkage mechanism drives the flushing mechanism to clean the multi-parameter sensor group 22.

[0039] In some embodiments, combined Figures 2 to 4 As shown, the multi-parameter lifting water quality monitoring mechanism also includes an electric telescopic rod 4 and a mounting cylinder 7. The electric telescopic rod 4 is fixedly connected to the support plate 1, and the telescopic end of the electric telescopic rod 4 is vertically downward. It is best to set two electric telescopic rods 4. The telescopic end of the electric telescopic rod 4 is fixedly connected to the lifting horizontal plate 8. The mounting cylinder 7 is fixedly set at the bottom of the lifting horizontal plate 8, and the multi-parameter sensor group 22 is circumferentially distributed on the inner side of the mounting cylinder 7 near the top, and exists by being embedded in the inner wall of the mounting cylinder 7. The cable passes upward to the location of the data processing unit 5, and the cable retains a certain length to ensure the lifting and lowering movement of the multi-parameter sensor group 22; the swinging filtering mechanism is arranged below the mounting cylinder 7, and the self-cleaning mechanism is arranged above the mounting cylinder 7.

[0040] When water quality monitoring is required, the electric telescopic rod 4 is started to extend downward, and the electric telescopic rod 4 drives the installation tube 7 to descend through the lifting horizontal plate 8 until the installation tube 7 is immersed in water. The multi-parameter sensor group 22 distributed in this way is in contact with the water, which is convenient for collecting different data through different types of sensors. In addition, one side of the probe of the multi-parameter sensor group 22 is distributed on the inner side of the installation tube 7 and can be effectively protected.

[0041] In some embodiments, combined Figure 2 and Figure 4 As shown, the swing-type filtering mechanism includes a swing cylinder 16, a connecting shaft 25, a filter element 20 and an alternating extrusion mechanism. The swing cylinder 16 is arranged below the mounting cylinder 7. An elastic corrugated sleeve 17 is connected between the top of the swing cylinder 16 and the mounting cylinder 7. The elastic corrugated sleeve 17 is a rubber body and can be bent and deformed. Both sides of the bottom of the mounting cylinder 7 are fixedly connected with a hanger 24. The swing cylinder 16 is rotatably connected to the hanger 24 through the connecting shaft 25. The relative positions of the swing cylinder 16 and the connecting shaft 25 are fixed. The connecting shaft 25 can rotate around its own axis relative to the hanger 24. The filter element 20 is fixedly arranged at the bottom of the swing cylinder 16, and the alternating extrusion mechanism is arranged on the outside of the swing cylinder 16.

[0042] Among them, the alternating extrusion mechanism includes a one-way movable baffle 21, a vertical plate 9 and a fixed baffle 11. There are two one-way movable baffles 21, which are distributed on both sides of the swing cylinder 16. One side of each one-way movable baffle 21 is movably connected to the swing cylinder 16 through a rebound hinge. It should be noted that the rebound hinge is installed at the upper position of the connection side of the one-way movable baffle 21, and the end face of the connection side of the one-way movable baffle 21 is in contact with the outer wall of the swing cylinder 16, so that the one-way movable baffle 21 can be deflected unidirectionally upward from the horizontal position and can return to the horizontal position, but cannot be deflected downward from the horizontal position; there are two vertical plates 9, which are distributed on both sides of the swing cylinder 16. The vertical plates 9 are fixedly connected to the support plate 1, and each vertical plate 9 is longitudinally equidistantly distributed with multiple fixed baffles 11 that cooperate with the one-way movable baffle 21, and the one-way movable baffles 21 distributed on the two vertical plates 9 are longitudinally staggered, not horizontally aligned.

[0043] When the mounting tube 7 with the multi-parameter sensor group 22 is lowered and immersed in water, the one-way movable baffle 21 can be deflected upward relative to the swing tube 16 from the horizontal position. Therefore, during the descending process, the swing tube 16 and the one-way movable baffles 21 on both sides squeeze through the fixed baffles 11 distributed on both sides. Only the one-way movable baffle 21 is deflected, and the swing tube 16 is not deflected. When the mounting tube 7 needs to be raised with the multi-parameter sensor group 22, at this time, the one-way movable baffle 21 cannot be deflected downward relative to the swing tube 16 from the horizontal position. Therefore, during the raising process, when the one-way movable baffle 21 contacts and squeezes the fixed baffle 11, it will drive the swing tube 16 to move. Since the fixed baffles 11 distributed longitudinally on both sides are longitudinally misaligned, each time the swing tube 16 only has the one-way movable baffle 21 on one side squeeze and contact the corresponding fixed baffle 11. Due to the unilateral squeezing effect, the swing tube 16 will rely on the connecting shaft 25 to deflect to one side. Figure 7 As shown, during this process, the elastic bellows sleeve 17 is deformed to generate a rebound force. When the contacting one-way movable baffle 21 separates from the corresponding fixed baffle 11, the pendulum cylinder 16 swings back by relying on its own weight and the rebound force of the elastic bellows sleeve 17, and then continues to rise. The one-way movable baffle 21 on the other side of the pendulum cylinder 16 is squeezed by the corresponding fixed baffle 11, and this process is repeated, and the pendulum cylinder 16 realizes reciprocating swing.

[0044] It should be noted that the above-mentioned filter element 20 is a spherical structure, and filter holes are evenly distributed on the spherical structure. The filter element 20 facilitates water to pass through and contact the multi-parameter sensor group 22, while preventing large floating objects in the water from passing through and colliding with the multi-parameter sensor group 22, thereby achieving protection. Moreover, it is a spherical structure, and during the reciprocating swing of the pendulum tube 16, it is convenient to throw out attached floating objects or debris that penetrates the filter holes, and it is also convenient to accelerate the rapid outflow of water entering the pendulum tube 16 and the installation tube 7.

[0045] In some specific embodiments, elastic metal frames 18 are fixedly connected to both sides of the swing cylinder 16, and an impact ball 19 is fixedly connected to the top of the elastic metal frame 18. The mounting cylinder 7 is a cylinder made of elastic metal. During the swinging process of the swing cylinder 16, the elastic metal frame 18 on one side will move away from the mounting cylinder 7, and the elastic metal frame 18 on the other side will bend and deform to generate a rebound force. When the swing is reset, the elastic metal frame 18 that is away will rebound and hit the mounting cylinder 7 through the impact ball 19, thereby causing the mounting cylinder 7 to vibrate, and the vibration is transmitted to the multi-parameter sensor group 22, which facilitates the shaking off of attached impurities and further improves the cleaning effect.

[0046] In some specific embodiments, such as Figures 4 to 6As shown, the flushing mechanism includes a linkage shaft 12, a piston liquid-feeding cylinder 14 and an annular brush member. The linkage shaft 12 is rotatably arranged on the lifting horizontal plate 8. Specifically, a support block is vertically welded on the lifting horizontal plate 8, and the linkage shaft 12 passes through the support block horizontally and is rotatably connected to the support block through a bearing; one end of the linkage shaft 12 is connected to the connecting shaft 25 through a linkage mechanism, and the other end of the linkage shaft 12 is fixedly connected to the top plate 13, and the top plate 13 is symmetrically provided with two, and the bottom of the piston liquid-feeding cylinder 14 is fixedly connected to the output slide 15, the output The bottom of the slide tube 15 passes through the lifting horizontal plate 8 and extends to the inside of the mounting tube 7. The output slide tube 15 can slide longitudinally with the piston liquid feeding tube 14 relative to the lifting horizontal plate 8. A first supporting spring 30 is connected between the output slide tube 15 and the lifting horizontal plate 8. The bottom of the output slide tube 15 is also connected to an annular spray brush integral part for cleaning the multi-parameter sensor group 22. The initial height of the annular spray brush integral part is higher than the position of the multi-parameter sensor group 22. The piston liquid feeding tube 14 is internally connected with a piston block 27 in a sliding manner. The piston block 27 is connected to the piston block 27. A second support spring 28 is connected between the bottom of the piston liquid feeding cylinder 14. The specifications of the second support spring 28 are smaller than those of the first support spring 30. Under the same force conditions, the second support spring 28 is deformed before the first support spring 30. The top plate 13 is used to cooperate with the extrusion piston block 27. A limit block 29 that cooperates with the piston block 27 is fixedly connected to the inner wall of the piston liquid feeding cylinder 14. A clean water tank 37 is installed on the lifting horizontal plate 8. The clean water tank 37 stores distilled water for cleaning the multi-parameter sensor group 22. Or clean water, a one-way infusion valve component 31 is connected between the bottom of the clean water tank 37 and the bottom of the piston liquid feeding cylinder 14, the one-way infusion valve component 31 includes a hose and a one-way valve, the hose is connected to the clean water tank 37 and the piston liquid feeding cylinder 14, the one-way valve is used to allow the cleaning liquid to flow only from the clean water tank 37 to the piston liquid feeding cylinder 14, and cannot flow in the opposite direction; a one-way liquid outlet valve 32 is installed on the output slide pipe 15, the one-way liquid outlet valve 32 can only allow the liquid to flow from the inside of the piston liquid feeding cylinder 14 to the annular spray brush integrated part, and cannot flow in the opposite direction.

[0047] Among them, the annular spray brush integrated part includes an annular frame 33, a soft brush 34 and a nozzle 35. The annular frame 33 is fixedly arranged at the bottom of the output slide 15, and the soft brush 34 is circumferentially distributed on the outer ring of the annular frame 33. When the annular frame 33 rises and falls with the output slide 15, the soft brush 34 can wipe the multi-parameter sensor group 22. There are multiple nozzles 35, which are circumferentially distributed at the bottom of the annular frame 33. Each nozzle 35 corresponds to flushing a sensor or collector of the multi-parameter sensor group 22. When the annular frame 33 is in the initial position, the distributed nozzles 35 are just facing the multi-parameter sensor group 22; each nozzle 35 is connected to the bottom of the output slide 15 through the tube body, and the diameter of the tube body between the nozzle 35 and the output slide 15 is relatively thin to prevent the liquid in the piston liquid feeding cylinder 14 from flowing out at will.

[0048] In addition, the linkage mechanism includes a transmission wheel 23 and a transmission belt 26 . The transmission wheels 23 are coaxially fixedly connected to the connecting shaft 25 and the linkage shaft 12 , and the two transmission wheels 23 are connected by a transmission belt 26 .

[0049] During the reciprocating swing of the pendulum cylinder 16, the connecting shaft 25 continuously rotates forward and reverse. During this process, the connecting shaft 25 drives the linkage shaft 12 to rotate synchronously through the transmission wheel 23 and the transmission belt 26. During the forward and reverse rotation of the linkage shaft 12, the top plate 13 on one side squeezes the piston block 27. Since the specification of the second support spring 28 is smaller than that of the first support spring 30, under the same force conditions, the second support spring 28 is deformed before the first support spring 30, so the piston block 27 slides downward relative to the piston liquid feeding cylinder 14. During this process, the internal cleaning liquid is squeezed out and output through the output slide pipe 15, and then sprayed through each nozzle 35 to rinse the distributed multi-parameter sensor group 22. In this process, the second support spring 28 is compressed and deformed, and the first support spring 30 has not yet deformed. When the piston block 27 drops to the position of the limit block 29 and cannot continue to drop, the top plate 13 continues to deflect and pushes the piston block 27 downward. At this time, the piston block 27 is blocked by the limit block 29, which will drive the entire piston liquid feeding cylinder 14 to descend, and the piston liquid feeding cylinder 14 will drive the output slide 15 to slide downward, and the output slide 15 will drive the annular frame 33 to descend, and the annular frame 33 will descend with the distributed soft brushes 34, which is convenient for brushing the multi-parameter sensor group 22, and convenient for cleaning the used multi-parameter sensor group 22 to a certain extent each time, reducing the impact on the next monitoring result, and during the descending process of the output slide 15, the first support spring 30 is stretched to generate a rebound force. When the top plate 13 is reset, the piston block 27 is reset by the second support spring 28, thereby facilitating the suction of cleaning liquid from the clean water tank 37 through the one-way infusion valve 31 for replenishment. At the same time, the output slide 15 rises and resets by relying on the rebound force of the first support spring 30, and so on. It is convenient to realize multiple cleaning of the multi-parameter sensor group 22 during the process of the lifting cross plate 8 and the swing cylinder 16 rising.

[0050] In some specific embodiments, a V-shaped baffle 3 is fixedly connected to the side of the support plate 1 away from the driving paddle 6. The V-shaped baffle 3 is on the forward side of the entire device to facilitate pushing away floating objects in the water during the forward process.

[0051] In some specific embodiments, such as Figure 2As shown, the buoyancy mechanism includes a float plate 2 and a floating airbag 10. The float plate 2 is fixedly connected to the bottom of the support plate 1 through a bracket. The float plate 2 is made of buoyancy material. The floating airbag 10 is fixedly arranged at the bottom of the float plate 2. The floating airbag 10 and the float plate 2 cooperate to make the entire device float on the water surface while preventing the raised installation tube 7 and the multi-parameter sensor group 22 from contacting the water. In order to ensure that the installation tube 7 can be raised and lowered to contact the water, a through hole 36 is opened on the float plate 2.

[0052] A monitoring method for a water quality monitoring device, the specific steps are as follows:

[0053] The first step is to make the entire water quality monitoring device float on the water surface by relying on the buoyancy mechanism, and then control the driving paddle 6 to operate and drive the entire water quality monitoring device to move to different positions on the water surface;

[0054] Step 2: Control the multi-parameter lifting water quality monitoring mechanism to descend, so that the multi-parameter sensor group 22 descends and is immersed in the water. The multi-parameter sensor group 22 collects various water quality values. During the collection process, the swing filter mechanism protects the multi-parameter sensor group 22.

[0055] Step 3: After data collection is completed at one location, the multi-parameter lifting water quality monitoring mechanism is controlled to rise; during the lifting process of the multi-parameter lifting water quality monitoring mechanism, the swing filter mechanism swings back and forth to throw off the attached garbage and debris;

[0056] Step 4: During the reciprocating swing of the swing filter mechanism, the swing filter mechanism drives the flushing mechanism through the linkage mechanism to clean the multi-parameter sensor group 22, thereby reducing the impact on the next water quality monitoring result.

[0057] In order to facilitate the understanding of the embodiments of this solution by those skilled in the art, the working principle of the water quality monitoring device of this solution is briefly described in combination with specific application scenarios:

[0058] When water quality monitoring is required, the electric telescopic rod 4 is activated to extend downward, and the electric telescopic rod 4 drives the mounting tube 7 to descend through the lifting horizontal plate 8 until the mounting tube 7 is immersed in the water. The multi-parameter sensor group 22 thus distributed is in contact with the water, making it convenient to collect different data through different types of sensors; and the swing tube 16 and the filter element 20 are used to filter the water that contacts the multi-parameter sensor group 22 to prevent floating debris from damaging the sensors.

[0059] When the acquisition of a position data is completed, the electric telescopic rod 4 is controlled to retract, and the installation cylinder 7 and the distributed multi-parameter sensor group 22 are driven to rise through the lifting cross plate 8. It should be noted that in the process of the installation cylinder 7 carrying the multi-parameter sensor group 22 descending and being immersed in the water, since the one-way movable baffle 21 can deflect upward from the horizontal position relative to the swing cylinder 16, during the descent process, the swing cylinder 16 carries the one-way movable baffles 21 on both sides to squeeze through the fixed baffles 11 distributed on both sides, and only the one-way movable baffle 21 is deflected, and the swing cylinder 16 is not deflected. When the installation cylinder 7 needs to be lifted with the multi-parameter sensor group 22, at this time, since the one-way movable baffle 21 cannot deflect downward from the horizontal position relative to the swing cylinder 16, when the one-way movable baffle 21 contacts and squeezes the fixed baffle 11 during the lifting process, it will drive the swing cylinder 16 to move. The distributed fixed baffles 11 are longitudinally staggered. Each time, only the one-way movable baffle 21 on one side of the pendulum drum 16 squeezes and contacts the corresponding fixed baffle 11. Due to the one-sided squeezing effect, the pendulum drum 16 will rely on the connecting shaft 25 to deflect to one side. During this process, the elastic bellows sleeve 17 deforms and generates a rebound force. When the contacting one-way movable baffle 21 is separated from the corresponding fixed baffle 11, the pendulum drum 16 relies on its own weight and the rebound force of the elastic bellows sleeve 17 to swing back, and then continues to rise. The one-way movable baffle 21 on the other side of the pendulum drum 16 is squeezed with the corresponding fixed baffle 11. This is repeated, and the pendulum drum 16 realizes reciprocating swing. During the reciprocating swing of the pendulum drum 16, it is convenient to throw out attached floating objects or debris that penetrates the filter holes. At the same time, it is also convenient to accelerate the rapid outflow of water entering the pendulum drum 16 and the installation cylinder 7, so as to facilitate rapid water quality monitoring at the next position.

[0060] During the reciprocating swing of the pendulum cylinder 16, the connecting shaft 25 continuously rotates forward and reverse. During this process, the connecting shaft 25 drives the linkage shaft 12 to rotate synchronously through the transmission wheel 23 and the transmission belt 26. During the forward and reverse rotation, the linkage shaft 12 squeezes the piston block 27 through the top plate 13 on one side. Since the specifications of the second support spring 28 are smaller than those of the first support spring 30, under the same force conditions, the second support spring 28 is deformed before the first support spring 30, and the piston block 27 slides downward relative to the piston liquid feeding cylinder 14. During this process, the internal cleaning liquid is squeezed out and output through the output slide pipe 15, and then sprayed out through each nozzle 35 to flush the distributed multi-parameter sensor group 22. In this process, the second support spring 28 is compressed and deformed, and the first support spring 30 has not yet deformed. When the piston block 27 drops to the position of the limit block 29 and cannot continue to drop, the top plate 13 continues to deflect and pushes the piston block 27 downward. At this time, the piston block 27 is blocked by the limit block 29, and the entire piston liquid feeding cylinder 14 is driven to descend, and the piston liquid feeding cylinder 14 drives the output slide 15 to slide downward, and the output slide 15 drives the annular frame 33 to descend, and the annular frame 33 is lowered with the distributed soft brushes 34, which is convenient for brushing the multi-parameter sensor group 22, and is convenient for cleaning the used multi-parameter sensor group 22 to a certain extent each time, reducing the impact on the next monitoring result. In the process of the output slide 15 descending, the first support spring 30 is stretched to generate a rebound force. When the top plate 13 is reset, the piston block 27 is reset by the second support spring 28, thereby facilitating the suction of cleaning liquid from the clean water tank 37 through the one-way infusion valve 31 for replenishment. At the same time, the output slide 15 rises and resets by relying on the rebound force of the first support spring 30, and so on. It is convenient to realize multiple cleaning of the multi-parameter sensor group 22 during the process of the lifting cross plate 8 and the swing cylinder 16 rising.

All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
