Description

Technical Field

[0001] The utility model relates to the technical field of sinking and floating flow-making devices, in particular to a sinking and floating flow-making device. Background Art

[0002] The process of restoring dissolved oxygen content in river ecosystems through biological and non-biological processes under natural conditions is called river purification and reoxygenation, which is used to maintain the health of river ecosystems and biodiversity. Traditional rivers usually adopt planting on both sides of the river bank and installing some filters to filter water quality and equipment to generate water flow in the river to maintain the health of river ecosystems. The filters cooperate with the flow of water to filter algae in the river, and the river flow generates reoxygenation. The effect of river management and maintenance is poor, and the effect of river management needs to be improved.

[0003] Therefore, the utility model provides a sinking and floating flow-making device that can quickly and effectively achieve river reoxygenation through vertical and horizontal water mixing. Utility Model Content

[0004] The purpose of the present invention is to provide a sinking and floating flow-generating device to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A sinking and floating flow-generating device, comprising a flow-generating structure body and an air intake system cooperating with the flow-generating structure body to intake air;

[0007] The main body of the flow-making structure includes a fixed anchor base arranged on the riverbed at the bottom of the river, a limiting bracket arranged on the fixed anchor base, and a hybrid lifting unit arranged in the limiting bracket;

[0008] The mixing and lifting unit includes a flow-generating shell arranged in a limiting bracket, an air-water mixing chamber arranged in the flow-generating shell, a power end seat arranged in the air-water mixing chamber, and an air diffuser is provided at the bottom of the power end seat, and the air diffuser is connected to the air pipe at the air outlet end of the air intake system;

[0009] The upper part of the flow-generating shell is provided with a flow-generating channel connected with the air-water mixing chamber.

[0010] Furthermore, the flow-generating structure body is arranged in the river and the height of the flow-generating structure body is lower than the water surface of the river, and the purpose of generating circulating output air masses to the river is achieved by the air masses generated by the flow-generating structure body on the water flow.

[0011] Furthermore, the air intake system includes a control cabinet located on the river bank and a fan connected to the control cabinet, and the air pipe at the output end of the fan is connected to the air diffuser.

[0012] Furthermore, a lifting sleeve is installed on the top of the limiting bracket, and the floating plate on the outer edge of the top of the flow-making shell is connected to the top of the lifting sleeve by screws. The lifting sleeve cooperates with the flow-making shell to rise upward due to the rising pressure of the air mass, and the floating plate is used to limit the flow-making shell at the limiting bracket to cooperate with the purpose of vertical lifting.

[0013] Furthermore, the flow-making channel is flared and is provided with a closing device for controlling the output of water flow. The closing device closes the flow-making channel when the air pressure in the air-water mixing chamber decreases. When the air pressure of the air mass in the air-water mixing chamber increases, the water in the flow-making shell is driven to rise, thereby outputting the water through the flow-making channel, forming a stronger vertical mixed water body and a horizontal mixed water body, thereby achieving the purpose of natural reoxygenation of the water in the river.

[0014] Furthermore, a counterweight block is provided at the bottom end of the flow-making shell for cooperating with the rising and falling of the flow-making shell, and a balance plate is provided at the outer edge of the counterweight block. The counterweight block is used to cause the flow-making channel to move downward due to the weight of the counterweight block when the air pressure in the air-water mixing chamber becomes smaller, and then the closing device is closed as the flow-making channel moves downward. The closing device is a plurality of arc-shaped plates fixed in a trumpet shape on the top of the flow-making channel. When the flow-making shell moves downward, the middle part of the arc-shaped plate is straightened as the flow-making shell moves downward, and the outer side walls of the arc-shaped plate are fitted to close the flow-making channel. When the flow-making shell moves upward, the arc-shaped plate is subjected to the rising pressure of the flow-making shell to expand outward, and then the outer walls of the arc-shaped plates are separated to form a channel for water output, thereby achieving the purpose of cooperating with the flow-making channel to output water.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] The sinking and floating flow-making device fixes a flow-making shell with a built-in air-water mixing chamber in the river by fixing an anchor base, and the air-water mixing chamber in the flow-making shell is connected to an air intake system, so that gas is injected into the air-water mixing chamber through the air intake system. Since the flow-making channel at the top of the flow-making shell is closed by a closing device, the gas stays in the air-water mixing chamber. When there is more gas in the air-water mixing chamber, the air pressure formed by the gas in the air-water mixing chamber collides with the other device, and the gas in the air-water mixing chamber and the water in the flow-making shell form an air mass that overflows from the flow-making channel. After the air mass overflows, the air pressure in the air-water mixing chamber decreases, and the closing device closes the flow-making channel again. The gas input by the air intake system forms air pressure in the air-water mixing chamber again, starting a new cycle. When the air mass is output through the flow-making channel, it will cause stronger vertical and horizontal mixing of the water in the air mass, and promote the natural reoxygenation process of the water, so as to achieve the effect of fast and effective vertical and horizontal water mixing. It has good air-water mixing effect, high unit efficiency, extremely low failure rate of main equipment, low noise, corrosion resistance, long service life, and low cost for river treatment. It can be widely used in lake eutrophication control, water source ecological algae control, river management, aquaculture, marine ecological restoration and other water ecological management.

[0019] 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 embodiments described 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 creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1 , the utility model provides a technical solution:

[0021] A sinking and floating flow-generating device comprises a flow-generating structure main body 1 and an air intake system 2 for cooperating with the flow-generating structure main body 1 to intake air. The input end of the air intake system 2 can be connected to a mains electricity supply, a solar power generation device or a wind power generation device according to the environment.

[0022] The flow-generating structure body 1 includes a fixed anchor base 3 provided on the riverbed at the bottom of the river, a limiting bracket 4 provided on the fixed anchor base 3, and a mixing lifting unit 5 provided in the limiting bracket 4;

[0023] The mixing and lifting unit 5 includes a flow-making shell 6 arranged in the limiting bracket 4, an air-water mixing chamber 7 arranged in the flow-making shell 6, a power end seat 8 arranged in the air-water mixing chamber 7, and an air diffuser 9 is provided at the bottom of the power end seat 8. The air diffuser 9 is connected to the air pipe 18 at the air outlet end of the air intake system 2. The air diffuser 9 is used to uniformly flow the gas output by the air intake system 2 into the air-water mixing chamber 7. The power end seat 8 is used to generate an upward lifting force on the flow-making shell 6 due to the lifting force generated by the rising air mass when the air mass rises;

[0024] A flow-generating channel 10 connected to the air-water mixing chamber 7 is provided on the upper portion of the flow-generating housing 6 .

[0025] The flow-generating structure body 1 is arranged in the river and the height of the flow-generating structure body 1 is lower than the water surface of the river. The flow-generating structure body 1 generates air masses for the water flow to achieve the purpose of generating circulating output air masses for the river.

[0026] The air intake system 2 includes a control cabinet 12 located on the river bank and a fan 11 connected to the control cabinet 12. The air pipe at the output end of the fan 11 is connected to the air diffuser 9. The control cabinet 12 is connected to the electronic components for monitoring the flow direction in the flow-generating structure body 1 through a line 17.

[0027] A lifting sleeve 13 is installed on the top of the limiting bracket 4, and the floating plate on the outer edge of the top of the flow-making shell 6 is connected to the top of the lifting sleeve 13 by screws. The lifting sleeve 13 cooperates with the flow-making shell 6 to rise upward due to the rising pressure of the air mass. The floating plate is used to limit the flow-making shell 6 at the limiting bracket 4 to cooperate with the purpose of vertical lifting.

[0028] The flow-making channel 10 is in an enlarged shape and is provided with a closing device 14 for controlling the output of water flow. The closing device 14 closes the flow-making channel 10 when the air pressure in the air-water mixing chamber 7 becomes smaller. When the air pressure of the air mass in the air-water mixing chamber 7 increases, the water in the flow-making shell 6 is driven to rise, thereby outputting the water through the flow-making channel 10, forming a stronger vertical mixed water body and a horizontal mixed water body, thereby achieving the purpose of natural reoxygenation of the water in the river.

[0029] The bottom end of the flow-making shell 6 is provided with a counterweight block 15 for cooperating with the rising and falling of the flow-making shell 6, and a balance plate 16 is provided on the outer edge of the counterweight block 15. The counterweight block 15 is used to cause the flow-making channel 10 to move downward due to the weight of the counterweight block 15 when the air pressure in the air-water mixing chamber 7 becomes smaller, and then the closing device 14 closes as the flow-making channel 10 moves downward. The closing device 14 is a plurality of arc-shaped plates fixed to the top of the flow-making channel 10 in a trumpet shape. When the flow-making shell 6 moves downward, the middle part of the arc-shaped plate is straightened as the flow-making shell 6 moves downward, and the outer side walls of the arc-shaped plate are fitted to close the flow-making channel 10. When the flow-making shell 6 moves upward, the arc-shaped plate is subjected to the rising pressure of the flow-making shell 6 and expands outward, and then the outer walls of the arc-shaped plates are separated to form a channel for water output, thereby achieving the purpose of cooperating with the flow-making channel 10 to output water.

[0030] The sinking and floating flow-making device fixes a flow-making shell 6 with a built-in air-water mixing chamber 7 in the river by fixing an anchor base 3, and the air-water mixing chamber 7 in the flow-making shell 6 is connected to the air intake system 2, so that gas is injected into the air-water mixing chamber 7 through the air intake system 2. Since the flow-making channel 10 at the top of the flow-making shell 6 is closed by the closing device 14, the gas stays in the air-water mixing chamber 7. When there is more gas in the air-water mixing chamber 7, the air pressure formed by the gas in the air-water mixing chamber 7 hits the separation device, and the gas in the air-water mixing chamber 7 and the water in the flow-making shell 6 form an air mass that overflows from the position of the flow-making channel 10. After the air mass overflows, the air pressure in the air-water mixing chamber 7 decreases, and the closing device 14 The flow-making channel 10 is closed again, and the gas input by the air intake system 2 forms air pressure in the air-water mixing chamber 7 again, starting a new cycle. When the air mass is output through the flow-making channel 10, it will cause relatively strong vertical and horizontal mixing of the water in the air mass, and promote the natural reoxygenation process of the water body, so as to achieve the effect of quickly and effectively mixing the water in the vertical and horizontal directions. It has the effects of good air-water mixing effect, high unit efficiency, extremely low failure rate of the main equipment, low noise, corrosion resistance, long service life, and low cost for river treatment. It can be widely used in lake eutrophication control, ecological algae control in water source areas, river management, aquaculture, marine ecological restoration and other water ecological management;

[0031] In actual application, the underwater position of the device is automatically adjusted according to the lake water level (for example, when the lake water level rises, the device also rises synchronously, and when the water level drops, the device also drops). Through aeration and internal flow-pushing devices, ripples appear on the lake surface and oxygen is increased. According to the different surface areas of the lake, corresponding equipment is added in proportion. The model of the fan 11 in the air intake system and the size parameters of the flow-making structure are the main equipment parameters. Other supporting facilities are equipped according to the main equipment parameters and can be customized according to actual needs.

[0032] When using the sinking and floating flow-making device, the parameters of the mixed flow-making system are as follows:

[0034] Wherein L represents the height of the sinking and floating flow-making device on the riverbed, and DN represents the water output of the flow-making channel 10.

[0035] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
