Description

Technical Field

[0001] The present invention relates to the field of ecological management, and in particular to an automatic river channel defoaming device and method for ecological management. Background Art

[0002] Ecological governance refers to the governance of ecological environment protection, especially in the governance of rivers. Due to the discharge of various water uses, it is very easy to generate a large number of bubbles in the river. There are many reasons for the generation of bubbles, as follows:

[0003] 1. Use of detergents: Detergents in daily life or industrial detergents are discharged into rivers. These detergents increase the surface tension of the water and lead to the formation of foam.

[0004] 2. Improper sewage treatment: When the rainwater and sewage diversion system is not complete, some industrial and domestic sewage is directly discharged into the river. The detergents contained in these sewage cause white foam.

[0005] 3. Activated sludge treatment issues: During the sewage treatment process, if the activated sludge load is too high or aeration is excessive, white foam will also be produced.

[0006] 4. Influx of external substances: Non-hazardous chemicals such as laundry detergent flowing into the river can also cause the formation of foam.

[0007] These foams may have a certain impact on the environment. When dealing with such problems, appropriate measures must be taken to reduce or eliminate foam and protect the water environment.

[0008] A search disclosed an eco-friendly river channel automatic defoaming device and method thereof, CN117899532A, which is used to eliminate bubbles in the river channel by spraying disinfectant water or defoaming agent into the river channel. This method has the following shortcomings:

[0009] 1. Defoaming treatment is carried out by directly spraying chemicals into the river. The basic principle is to directly apply chemical agents to the water body through the spraying device to achieve the purpose of eliminating foam;

[0010] However, in the implementation of this method, the agents often contain some ingredients that have potential impacts on organisms. When these ingredients act on the river aquatic ecosystem, they may have adverse effects on plants, fish and other organisms, or even cause harm;

[0011] Therefore, when using this method, the possible environmental risks are not fully considered.

[0012] Second, the device is installed on the hull, which means that relevant personnel are required to operate the defoaming process, which results in relatively high labor costs and many challenges for operators. The high temperature not only tests their physical strength and endurance, but also has a direct impact on their work efficiency and safety. Summary of the invention

DETAILED DESCRIPTION

[0063] 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.

[0064] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0065] For example, see Figures 1 to 15 , an automatic defoaming device for river channel for ecological management, comprising a carrying box 1, the carrying box 1 is installed on the river channel through a lifting assembly, and the carrying box 1 is open on one side:

[0066] Mounting slots 26 are provided on both sides of the carrying box 1;

[0067] The shunt box 2 and the discharge pipe 10 are fixed to one side of the carrying box 1, and the discharge pipe 10 is fixed to the other side of the carrying box 1. The shunt box 2 and the discharge pipe 10 are both connected to the carrying box 1 through the mounting groove 26. The carrying box 1 is equipped with a pump air assembly, which is connected to the shunt box 2. The discharge pipe 10 cooperates with the collection assembly installed on one side of the river channel;

[0068] A plurality of nozzles 24 are fixed on the diverter box 2, and the nozzles 24 are arranged at an angle;

[0069] The inclined member 29 is fixed to the inner side of the carrying box 1 and is located at the open side of the carrying box 1. The carrying box 1 is divided into a foam inlet 32 ​​and a separation chamber 31 by the inclined member 29. The bottom of the separation chamber 31 is provided with a discharge hole 25;

[0070] A top groove is connected with a box cover 3.

[0071] In the embodiment of the present invention, please refer to Fig.13 and Fig.14 The flow of river water drives the foam in the river to flow along the flow direction, and the water flow drives the foam to move into the sub-carrying box 1 and the foam moves into the separation chamber 31 along with the movement of the water flow;

[0072] The water level in the figure is a specific requirement of the present invention after installation, and in order to meet this state, the lifting assembly can be adjusted in real time;

[0073] The foam moves along the water level line, and the inclined member 29 plays a role similar to a "dam". The water level line of the river will not change without external interference, that is, the water level heights on the left and right sides of the inclined member 29 are the same. The reason why water and foam move into the separation chamber 31 is that the inclined member 29 is set in an oblique shape, and the force of the water flow makes it flow into the separation chamber 31. In this process, a water level difference is formed, so that the foam and the flowing water move into the separation chamber 31 at the same time, and the water continues to flow through the discharge hole 25 at the bottom of the separation chamber 31, while the foam will remain in the separation chamber 31, and the foam is limited by the water level difference;

[0074] When the water flows, it also drives the pump air component to work, pumping air into the diverter box 2 through the pump air component, and after diversion through the diverter box 2, it is sprayed into the separation chamber 31 through the nozzle 24, and the foam is blown into the discharge pipe 10 through the airflow, and then transported to the collection component through the discharge pipe 10 for collection / collection processing.

[0075] Embodiment 2: The technical solution of the embodiment of the present invention is different from that of embodiment 1 in that: two inclined plates 12 are fixed to the open side of the carrying box 1, and the two inclined plates 12 are respectively located at two ends of the carrying box 1, and the two inclined plates 12 are both inclined.

[0076] In the embodiment of the present invention, considering that there may be bends on both sides of the river channel, so that the carrying box 1 cannot be installed close to the edge of the river channel, inclined plates 12 can be installed on both sides of the carrying box 1 to guide the position not covered by the carrying box 1, so that the water flow and foam at the position not covered by the carrying box 1 move toward the carrying box 1;

[0077] Of course, the present invention only illustrates the structure and principle. In actual production and use, the length of the inclined plate 12 may change to a certain extent and may be adjusted according to actual conditions. The present invention does not make specific limitations and can meet the needs.

[0078] The pump air assembly comprises a piston cylinder 5 fixed on the carrying box 1, a piston rod 6 is sealed and slidably mounted in the piston cylinder 5, and the piston rod 6 is connected to a driving assembly mounted on the carrying box 1;

[0079] Among them, a piston is coaxially fixed to the end of the piston rod 6, and the piston rod 6 is sealed and slidably connected with the piston cylinder 5 through the piston;

[0080] A delivery pipe 4 connected to the piston cylinder 5 is fixed at one end away from the piston rod 6 , and the delivery pipe 4 is connected to the diverter box 2 .

[0081] In the embodiment of the present invention, the piston rod 6 and the piston cylinder 5 in the present invention are the same as the distance between the "gas cylinder" in the prior art. When the driving assembly is working, the piston rod 6 is driven to reciprocate, and then the gas is pumped into the diverter box 2 through the delivery pipe 4;

[0082] The reason why the present invention does not use an air pump is that the device needs to be installed in water all year round, and the device needs to pump air almost continuously. Therefore, the air pump needs to deal with various unreliable problems outdoors, and the possibility of damage is relatively high. The air pump needs a steady supply of electricity for power supply. Here, relevant technicians may think of photovoltaic panels for power supply. For example, in rainy weather, the photovoltaic panels cannot generate enough electricity. The pumping of air in the present invention directly affects whether it can operate normally. Here, the present application does not use an air pump to directly pump air, and the cost of the air pump is also relatively high.

[0083] The driving assembly includes a worm wheel 15 rotatably mounted on the carrying box 1, a transmission disc 8 is coaxially fixed on the worm wheel 15, a transmission plate 7 is rotatably mounted on the end of the transmission disc 8, the transmission plate 7 is rotatably connected to the piston rod 6, and a worm 22 meshing with the worm wheel 15 is rotatably mounted on one side of the worm wheel 15;

[0084] A transmission rod 23 is installed on the carrier box 1, which penetrates the carrier box 1 and is rotatably connected to the carrier box 1. One end of the transmission rod 23 is connected to the worm gear 15 through the bevel gear set 14. The other end of the bevel gear set 14 is coaxially fixed with an impeller 19.

[0085] A diverter plate 18 is also fixed to the bottom of the carrying box 1 .

[0086] In the embodiment of the present invention, when the water flows toward the impeller 19, the water flow on one side of the impeller 19 is blocked by the diverter plate 18 from directly impacting the impeller 19, so that the water flow can only impact one side of the impeller 19 when flowing toward the impeller 19, thereby causing the impeller 19 to rotate;

[0087] When the impeller 19 rotates, the transmission rod 23 is driven to rotate, and the transmission rod 23 drives the worm 22 to rotate through the transmission chain 13, and then drives the transmission plate 8 to rotate through the meshing of the worm 22 and the worm wheel 15. When the transmission plate 8 rotates, the piston rod 6 is driven to reciprocate through the transmission plate 7;

[0088] The reason why the present invention adopts the worm 22 and the worm wheel 15 is that the water flow speed in the river channel where the bubbles need to be removed is usually not very fast. Although the impeller 19 can be driven to rotate during the flow, the torque generated by the impeller 19 is not enough to drive the transmission plate 8 to rotate, because the transmission plate 8 needs to push the piston rod 6 through the transmission plate 7 when rotating, and thus the transmission plate 8 needs a relatively large force when rotating. As is known to all, when the worm wheel 15 is driven to rotate by the worm 22, it has the characteristics of deceleration and torque increase, that is, the worm 22 can be driven to rotate by the force generated by the rotation of the impeller 19, and the worm wheel 15 can be driven to rotate by the worm 22 to increase the torque, so as to meet the torque required for the rotation of the transmission plate 8;

[0089] It should be noted that the transmission disc 8 in the present invention rotates as a disc in the initial design stage, and the transmission plate 7 rotates at the eccentric position of the disc. In order to reduce the volume and weight of the transmission disc 8, the redundant part thereof is cut off to obtain the shape of the transmission disc 8 shown in the figure;

[0090] Furthermore, following the description of the air pump not used in the above invention, the power source of this embodiment is the impact force of the river flow, which drives the transmission plate 8 to rotate in a purely mechanical way. Compared with the air pump, it is simpler and more direct, and will not be affected by the weather. It is relatively more practical and has a low cost.

[0091] It should also be noted that the bevel gear set 14 in the present invention includes two bevel gears meshing with each other, and the two bevel gears are coaxially fixed to the rotating shaft of the worm 22 and the transmission rod 23 respectively.

[0092] Embodiment 3, the technical solution of the embodiment of the present invention is different from that of embodiment 2 in that: the lifting assembly includes at least two screw rods 16 rotatably mounted on both sides of the carrying box 1, and the outer side of the screw rods 16 is sleeved with an internal threaded tube 17 threadedly matched therewith, and the internal threaded tube 17 is fixed in the river channel;

[0093] The two screw rods 16 are connected via a transmission chain 13 , and a plurality of limiting rollers 11 for limiting the transmission chain 13 are rotatably mounted on the carrying box 1 , wherein one of the limiting rollers 11 is connected to a driving member mounted on the carrying box 1 .

[0094] In the embodiment of the present invention, when the driving member is working, one of the limiting rollers 11 is driven to rotate, and the limiting roller 11 drives the transmission chain 13 to convey, so as to drive the two screw rods 16 to rotate synchronously. When the screw rod 16 rotates, the threaded engagement with the internal threaded tube 17 drives the carrying box 1 to rise / fall vertically;

[0095] The screw transmission method is used to drive the carrying box 1 to move up and down, which requires a small driving force and has a high lifting accuracy.

[0096] The driving member includes a protective box 9 fixed on the carrying box 1, a motor 20 is fixed in the protective box 9, an output shaft of the motor 20 passes through the bottom of the protective box 9 and is coaxially fixed with one of the limiting rollers 11, and a processing device 21 electrically connected to the motor 20 is also fixed in the protective box 9;

[0097] A first water level sensor 27 is fixed to the top of the inner wall of the carrying box 1, and a second water level sensor 28 is also fixed to the tilting member 29. Both the first water level sensor 27 and the second water level sensor 28 are electrically connected to the processing device 21;

[0098] A photovoltaic panel cover 901 is detachably mounted on the top of the protection box 9. Two inclined surfaces are arranged on the top of the photovoltaic panel cover 901, and photovoltaic panels are embedded in both inclined surfaces.

[0099] In the embodiment of the present invention, when the water level of the river channel decreases, the second water level sensor 28 is exposed to the water surface, and then the second water level sensor 28 generates driving data to the processing device 21, and then the processing device 21 drives one of the limiting rollers 11 to rotate, so as to drive the carrying box 1 to descend vertically;

[0100] When the water level rises, the first water level sensor 27 will be submerged, so that a driving signal is sent to the processing device 21 through the first water level sensor 27, and then the limiting roller 11 is driven to rotate through the processing device 21 to drive the carrying box 1 to be vertically lowered;

[0101] The distance between the first water level sensor 27 and the second water level sensor 28 is the value at which the water level drops or rises without affecting the operation of the device. If the water level drops or rises a little below or above this value, the device will be quickly adjusted.

[0102] It should be noted that the photovoltaic panel on the photovoltaic panel cover 901 of the present invention is electrically connected to the battery installed in the protective box 9, and the battery is used to supply power to the motor 20, the processing device 21, the first water level sensor 27, and the second water level sensor 28. The photovoltaic panel can charge the battery in normal weather and store the battery through the battery. The battery is not shown in the figure;

[0103] The battery in the present invention is a storage battery that can be charged and discharged, and the photovoltaic panel is connected to the storage battery through an inverter. This method is also the most common method of connecting the storage battery and the photovoltaic panel, and will not be elaborated on in detail;

[0104] The area of ​​the photovoltaic panel cover 901 is larger than the protective box 9 to prevent rain, and the photovoltaic panel cover 901 and the protective box 9 are also commonly used in the "umbrella" configuration for rain protection;

[0105] It should also be noted that since the present invention adopts thread-driven lifting, the power required is relatively small, so a smaller and less energy-efficient motor can be used, and the motor does not work continuously, but only works when the water level fluctuates greatly. The electric energy stored in the battery is sufficient for its use for several months or even years, and the battery can be charged through the protective plate. Although there will be rainy weather, the electric energy stored in the battery is sufficient for use, and rainy weather will not occur all year round.

[0106] The collection assembly includes a foam collecting box 34, in which a porous plate 37 is fixed;

[0107] A top cover 36 is fixed on the top of the foam collecting box 34, and a through hole is opened on the top cover 36;

[0108] A reflux pipe 35 communicating with the foam collecting box 34 is fixed on one side thereof, and the reflux pipe 35 is connected with the river channel.

[0109] In the embodiment of the present invention, after the foam is blown into the discharge pipe 10 by the air flow, the foam will move into the foam collecting box 34 under the guidance of the discharge pipe 10 and fall onto the porous plate 37, and a small amount of water mixed in the foam will flow to the bottom of the foam collecting box 34 through the plug hole on the porous plate 37, and be discharged to the river through the return pipe 35;

[0110] Among them, after filtering through the porous plate 37, the foam will be on the porous plate 37, and after accumulation, the foam can be eliminated by destroying the structure to make it burst;

[0111] The porous plate 37 in this embodiment is set to the current shape with a reserved installation position for the destruction structure. The core component of the destruction group structure is an igniter, through which the flammable gas sprayed by the destruction structure is ignited to cause the foam to burst through the generated flame. The destruction structure is not shown in the accompanying drawings.

[0112] A protective tube 33 is fixed in the carrying box 1, and the protective tube 33 is sleeved on the outside of the transmission rod 23;

[0113] The tilting member 29 is also provided with a weight-reducing groove 30 .

[0114] In the embodiment of the present invention, untreated water in general rivers is corrosive to a certain extent. In order to ensure the service life of the transmission rod 23, the bearing of the transmission rod 23 is installed in the protective tube 33 so that the bearing is not in contact with water, thereby improving the service life of the transmission rod 23 to a certain extent and improving its stability to a certain extent.

[0115] The present invention also provides an automatic defoaming method for a river channel for ecological management. The automatic defoaming method for a river channel for ecological management adopts an automatic defoaming device for a river channel for ecological management, and comprises the following steps:

[0116] Step 1: Install the carrying box 1 on the river channel through the lifting assembly;

[0117] Step 2: The water flow through the river channel drives the foam to move to the foam inlet 32 ​​in the carrying box 1, and at the same time, the water flow through the river channel drives the impeller 19 to rotate;

[0118] Step three, when the impeller 19 rotates, the transmission disc 8 is driven to rotate through the transmission rod 23, and when the transmission disc 8 rotates, the piston rod 6 is driven to reciprocate through the transmission plate 7 to pump gas into the diverter box 2. The gas is diverted by the diverter box 2 and then sprayed out through the nozzle 24 to blow the foam in the foam inlet 32 ​​into the discharge pipe 10, and moves to the foam collection box 34 under the guidance of the discharge pipe 10, so that the foam is collected or processed by the foam collection box 34.

[0119] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention.
