Description

Technical Field

[0001] The utility model relates to the technical field of water environment management, in particular to a device which can adjust the height and intercept river garbage by using bubbles. Background Art

[0002] Rivers and lakes that are closely related to human life often have the problem of floating garbage polluting the environment. A large amount of floating garbage gathers on the water surface, which has an adverse impact on the water quality, water landscape, aquatic life, navigation capacity and power generation capacity of the river. How to solve this problem efficiently and reasonably is the key to improving the water environment and improving people's well-being.

[0003] In recent years, bubble barriers have been widely used as a new type of technology to intercept floating objects on the surface of water bodies. The core principle of this technology is to generate bubble plumes in the water to form a belt-shaped barrier to intercept floating objects, making them easier to collect and treat.

[0004] However, the traditional bubble barrier has a single effect. For example, the application number is 202210357943.4, and the name is "A hydrodynamic bubble barrier device", which includes a column seat, a semi-turn assembly, a bubble assembly, a pull rod I, a pull rod II and a cross bar. The hydrodynamic bubble barrier device is novel in conception, reasonable in structure, energy-saving and environmentally friendly, and uses the power of flowing water to generate bubbles. The bubbles form a barrier to block and guide the flow of garbage in the water. It can only provide a fixed barrier to intercept floating objects on the water surface by fixing the air pipe on the riverbed, and its bubble parameters are usually fixed. When the water depth of the river changes, this method has problems such as low efficiency, rigid model, and high energy consumption.

[0005] Therefore, it is of practical significance to design an optimization scheme that can change the height of bubble generation according to the water depth of the river, so that the device has flexibility and adaptability, so as to better cope with the situation of floating objects in different waters and more efficiently intercept floating garbage in the river.

The base 11 is made of a material with a density of 4.51×10 3 kg / m 3 The titanium alloy material is used to prevent the river water from corroding it. The base 11 is fixedly installed on the riverbed by bolts 12. The bottom of the lifting device is connected to the fixing device 10. The lifting device is vertically arranged and the top is higher than the water surface of the river. Assuming the highest historical water depth of the river is H, the height of the lifting device is L, and the unit is m, then L≥1.2H. The lifting device includes a screw rod 22 and a guide rod 21 installed between the fixing device 10 and the limit switch 42; the screw rod 22 is a cylindrical threaded rod, and a thread is provided at the connection between the trachea support rod 31 and the screw rod 22. The screw rod 22 is threadedly engaged with the trachea support rod 31, and the trachea support rod 31 is fixed on the screw rod 22. The trachea support rod 31 moves up and down with the rotation of the screw rod 22. There are two guide rods 21, which are located on both sides of the screw rod 22. The screw rod 22 is the same length as the two guide rods 21. The guide rod 21 has a strip groove on the side close to the screw rod 22. The sliding connection between the trachea support rod 31 and the guide rod 21 has a protrusion matching the size of the strip groove. The guide rod 21 can make the trachea support rod 31 slide up and down but not rotate with the screw rod 22, and also guide the movement of the trachea support rod 31.

[0030] The bubble generator 30 includes an air pipe support rod 31, an air pump 33 and an air pipe 32; the air pipe support rod 31 is perpendicular to the lifting device and arranged along the width of the river channel, and the air pipe support rod 31 is slidably connected to the lifting device; the air pump 33 is installed on the river bank; the air pipe 32 includes a top section, a bottom section and a middle section; the top section is connected to the air pump 33, and the air pump 33 can inject air into the air pipe 32; the bottom section is laid on the air pipe support rod 31, and there is a strip groove in the middle of the air pipe support rod 31 for placing the air pipe 32.

The bubble barrier takes air as the origin, and the air pump 33 injects air into the air pipe 32, transmits it underwater, and sprays it out at the nozzle of the air pipe 32. The gas appears as a bubble plume in the water, forming a bubble barrier that runs through the river channel, blocking floating objects in the river channel that flow downstream. Preferably, the distance between adjacent holes on the air pipe 32 is 0.2~0.3m, and the diameter of the hole is 0.03~0.06m, and the specific size depends on the river channel conditions; the middle section is telescopically connected between the top section and the bottom section; the bottom section of the air pipe 32 bypasses the screw rod and is connected to the middle section, and the middle section of the air pipe 32 is located on the other side of the air pipe support rod 31. Assuming that the width of the river channel is B, the unit is m, then the length and width of the fixing device 10 is 0.3B, and the actual application size can support the entire device. The length of the air pipe support rod 31 is 0.95~0.97B, so that the bubble barrier can cover the entire river channel and intercept the garbage in the entire river channel. The total length of the air pipe 32 is not less than B+1.2L, so that the air pipe 32 can move up and down with the air pipe support rod 31 without length restrictions, and can be better connected to the air pump 33. Preferably, the length of the bottom section of the trachea 32 is consistent with the length of the trachea support rod 31, the width of the trachea support rod 31 is equal to the distance between the two guide rods 21, and the guide rods 21 can fit with the trachea support rod 31 so that the trachea support rod 31 can move up and down smoothly under the guidance of the guide rods 21.

[0031] The power box 60 is installed on the top of the lifting device, located above the water surface and exposed to the air. The top of the power box 60 can be opened for easy maintenance by the staff. The shell is made of a 7.93×10 3 kg / m 3It is made of 301 stainless steel to ensure its normal service life. The height of the power box 60 is 0.5~0.7m, which can be set according to actual conditions, including a transmission device 40 and a control device 50; the transmission device 40 includes a motor 41 and a limit switch 42; the motor 41 is arranged inside the box body of the power box 60, the motor 41 is connected to the air pump 33, and the motor 41 is connected to the lifting device, specifically, the motor 41 controls the rotation of the screw rod 22; the limit switch 42 is arranged at the bottom of the power box 60, connected to the top of the lifting device, specifically connected to the top of the screw rod 22, and its function is that when the air pipe support rod 31 rises to a suitable height, the limit switch 42 receives an electrical signal and immediately stops the rotation of the screw rod 22. The control device 50 includes a liquid level sensor 51, a processor 53 and a controller 52 installed inside the power box 60; the liquid level sensor 51 is connected to the processor 53 by electrical signals, and the liquid level sensor 51 measures the deepest water level of the river, and can measure the deepest water level of the river at time t in real time, and convert the pressure signal of the water level information into an electrical signal through the circuit and transmit it to the processor 53; the processor 53 is connected to the controller 52 by electrical signals, and the processor 53 compares the water level at time t with the water level information at the time when the height of the air pipe support rod 31 was last adjusted. If the water level difference between the deepest water level at time t and the water level at the time when the height of the air pipe support rod 31 was last adjusted reaches 0.5m, the air pipe 32 in the bubble generator 30 rises 0.5m, and the processor 53 transmits the electrical signal to the controller 52; the controller 52 is connected to the motor 41 and the limit switch 42 by electrical signals, and the controller 52 controls the transmission device 40 to make the air pipe support rod 31 rise to a suitable height. The wires used by each device in the power box 60 are all routed inside the power box 60.

[0032] The method of using the height-adjustable bubble-based river garbage interception device is as follows:

[0033] In the first step, the liquid level sensor 51 measures the water depth: when the water level of the river rises, the liquid level sensor 51 measures the deepest water level of the river at time t, and converts the pressure signal of the water level information into an electrical signal through a circuit and transmits it to the processor 53.

[0034] In the second step, the processor 53 compares the water level information and can transmit a signal to the controller 52: the processor 53 compares the water level at time t with the water level information at the time when the height of the air pipe support rod 31 was last adjusted. If the difference between the deepest water level at time t and the water level at the time when the height of the air pipe support rod 31 was last adjusted reaches 0.5m, the air pipe 32 in the bubble generator 30 rises by 0.5m, and the processor 53 transmits an electrical signal to the controller 52.

[0035] In the third step, the controller 52 controls the transmission device 40 to raise the trachea support rod 31 to an appropriate height: when the water level difference between the deepest water level at time t and the time when the height of the trachea support rod 31 was last adjusted reaches 0.5m or more, the motor 41 drives the screw rod 22 to rise according to the height that needs to be raised transmitted by the processor 53, and the distance between the trachea 32 hosting and the river surface becomes smaller. When the trachea support rod 31 reaches the corresponding height, the limit switch 42 stops the operation of the motor 41 and stops the rotation of the screw rod 22.

[0036] During the first step to the third step, the air pump 33 is always in working state, transmitting gas to the air pipe 32, and the nozzle of the air pipe 32 always creates bubbles underwater to form a bubble barrier. Compared with the previous technology, the utility model is a more efficient, more economical and more environmentally friendly river garbage interception method.

[0037] The preferred embodiments of the present invention are described in detail above. However, the present invention is not limited to the specific details in the above embodiments.
