Description

Technical Field

[0001] The present invention belongs to the technical field of water treatment, and particularly relates to an underwater multi-directional unfolding structure for a deep-water reoxygenation and film-forming device. Background Art

[0002] Membrane Aerated Biofilm Reactor technology (academic name MABR, commercial name EHBR) is a new type of sewage treatment technology that organically combines gas separation membrane technology and biofilm water treatment technology. The microbial film adheres and grows on the surface of the oxygen-permeable hollow fiber membrane. When the sewage flows around the hollow fiber membrane, the pollutants in the water body enter the biofilm under the action of concentration difference driving and microbial adsorption. Through biological metabolism and proliferation, they are utilized by the microorganisms, so that the pollutants in the water body are assimilated into microbial cells and fixed on the biofilm or decomposed into inorganic metabolites, thereby realizing the purification of the water body. It is an artificially enhanced ecological water treatment technology that can form a self-purifying water ecosystem with self-repair function in river and lake water bodies. MABR has technical advantages, engineering advantages, cost advantages and operation management advantages that cannot be compared with conventional water treatment technologies. During the operation of the MABR system, oxygen directly passes through the membrane wall and is utilized by the biofilm without passing through the liquid phase boundary layer, greatly reducing the mass transfer resistance of oxygen and being conducive to the improvement of the oxygen supply rate and oxygen utilization rate. In the biofilm, oxygen and the substrate are transferred in opposite directions. By controlling the oxygen supply amount, obvious stratification can be generated in the biofilm, so as to achieve the effects of simultaneous nitrification and denitrification and removal of organic matter. Many microorganisms with very different habits and large differences in living environments can coexist in the MABR biofilm and simultaneously play the roles of removing organic matter and removing phosphorus and nitrogen.

[0003] However, at present, most of the traditional MABR technologies adopt a method of fixedly laying the membrane rack on the bottom of the water. In actual use, the above method has large consumption of membrane components, low utilization rate, and requires a large number of pipeline connections. At the same time, the membrane rack is fixedly arranged at the bottom of the water, and the laying depth of the membrane rack cannot be changed according to the water depth, making it difficult to achieve multi-level water resource restoration at different water depths. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide an underwater multi-directional unfolding structure for a deep-water reoxygenation and film-forming device, so as to solve the problem that the membrane rack in the prior art is fixedly arranged at the bottom of the water, resulting in difficulty in realizing multi-level water resource restoration at different water depths.

[0009] Furthermore, gantry sliding frames are provided on the inner side of each edge of the hanging plate.

[0028] As Figures 1 to 6As shown, an underwater multi-directional expansion structure for a deep-water reoxygenation film hanging device comprises a mounting base plate, a winch is arranged on the mounting base plate, the movable end of the hoisting rope 2 on the winch passes through the mounting base plate, a hanging plate 3 is arranged below the mounting base plate, the movable end of the hoisting rope 2 on the winch is fixedly connected to the middle part of the hanging plate 3, and a plurality of groups of expansion structures are evenly distributed on the side circumference of the hanging plate 3, one group of expansion structures comprises a hollow mounting seat 4, one side of the mounting seat 4 is fixed on the hanging plate 3, and no end cover is arranged on the side surface of the mounting seat 4 away from the hanging plate 3, that is, this side is connected with the interior, which can also be understood as a through slide 6 arranged, a plurality of first connecting rods 7 and second connecting rods 8 are arranged on the mounting seat 4, the head and tail of the plurality of first connecting rods 7 are rotatably connected with each other, the head and tail of the plurality of second connecting rods 8 are rotatably connected with each other, the middle parts of the plurality of first connecting rods 7 and the middle parts of the plurality of second connecting rods 8 are rotatably connected one by one, and the end of the first connecting rod 7 arranged near the mounting seat 4 is rotatably connected to the inner part of the side of the mounting seat 4 connected with the interior. The cam 9 is provided with a plurality of springs, each of which is connected to the inner wall of the mounting seat 4. The cam 9 is provided with a plurality of springs, each of which is connected to the inner wall of the mounting seat 4. The cam 9 is provided with a plurality of springs, each of which is connected to the inner wall of the mounting seat 4. The cam 9 is provided with a plurality of springs, each of which is connected to the inner wall of the mounting seat 4. The cam 9 is provided with a plurality of springs, each of which is connected to the inner wall of the mounting seat 4. The cam 9 is provided with a plurality of springs, each of which is connected to the inner wall of the mounting seat 4. The cam 9 is provided with a plurality of springs, each of which is connected to the inner wall of the mounting seat 4.

[0029] It should be noted that when treating pollutants in water by hanging MABR membranes on this unfolded structure, an aeration function should also be provided, that is, a compressor and other components need to be provided. Therefore, a mounting shell 23 is provided on the mounting plate 1, one end of the mounting shell 23 is fixed to the edge of the mounting plate 1, and a winch is provided inside the mounting shell 23. A compressor is also provided inside the mounting shell 23, and the other end of the air supply pipe 14 is connected to the compressor. A float or the like can be provided on the mounting shell 23 to make it float on the water surface. At the same time, driving elements such as blades can also be provided to drive the entire device to move on the water surface, thereby realizing mobile repair on the water surface.

[0030] Then the working principle of the above technical solution is:

[0031] When the unfolding structure moves to the designated water area, by controlling the winch, its lifting rope 2 is elongated. That is, under the action of gravity, the unfolding structure will descend to the designated underwater depth. At this time, due to the setting of the spring 10, the included angle between the first connecting rod 7 and the second connecting rod 8 on the mounting seat 4 is at the maximum value. At this time, several first connecting rods 7 and second connecting rods 8 are in a contracted state. When the designated depth is reached, only by controlling the compressor to inject gas into the air duct, the airbag 13 will continuously expand at this time. The expanding airbag will receive an upward buoyancy force. That is, the increase in buoyancy will overcome the deformation torque of the spring 10, causing the spring 10 to deform, and then driving the slider 9 to move upward. While the slider 9 moves upward, it will drive the second connecting rod 8 to move upward. As a result, the included angle between the first connecting rod 7 and the second connecting rod 8 becomes smaller. Thus, the included angles between several first connecting rods 7 and second connecting rods 8 can be reduced, and the unfolding structure can be unfolded outward (the movement mode of the scissor link in the prior art can be referred to), and then drive the MABR membrane hung thereon to unfold for water treatment operations. After the water treatment in one area is completed, only the air inside the airbag 13 needs to be discharged (the control and implementation method of the air intake and exhaust of the airbag 13 are the prior art). That is, the spring 10 loses the action of the buoyancy force and then resets. That is, when resetting, it drives the second connecting rod 8 to reset, that is, drives the entire unfolding structure to retract. Then, by using the winch to lift the hanging plate 3 upward, the unfolding structure can be lifted close to the water surface, which is convenient for the movement of the entire device on the water surface. When water treatment is not carried out, the unfolding structure is in a contracted state, which can reduce the volume of the entire device.

[0032] It should be noted that the size of the airbag 13 can be set according to the actual situation. Because the magnitude of the buoyancy force F = ρgV_drain, the magnitude of the buoyancy force can be changed by controlling the inflated volume of the airbag 13. Thus, the compression amount of the spring 10 can be changed, and the unfolding degree of the unfolding structure can be changed. Further, different lengths of each unfolding structure can be unfolded underwater to adapt to different underwater environments. At the same time, each unfolding structure is independently controlled by the air supply pipe 14, so that multiple groups of unfolding structures can be controlled to unfold in different directions underwater.

[0033] At the same time, this unfolding method using buoyancy does not require using electric drive components to drive the first connecting rod 7 and the second connecting rod 8 underwater to make the unfolding structure perform unfolding and contracting operations. Such a setting method is safer to use and can improve the overall service life. Because if electric drive components are used, it is extremely easy to cause water ingress and damage due to sealing problems.

[0034] In one practicable manner, the hanging plate 3 is rectangular, and two groups of unfolding structures are arranged on one side of the rectangular hanging plate 3. Through grooves 5 are provided on the oppositely arranged sides of the two mounting seats 4 of the two groups of unfolding structures on one side of the hanging plate 3. A connecting rod 11 is arranged in the through groove 5. The two ends of the connecting rod 11 are respectively fixedly connected to the sliders 9 inside the two groups of unfolding structures. One end of the connecting rope 12 is fixedly arranged in the middle of the connecting rod 11, and the other end of the connecting rope 12 is fixed on the airbag 13. In this arrangement, the two groups of unfolding structures on one side of the hanging plate 3 are controlled in linkage, so that the movement heights of the sliders 9 in the two groups of unfolding structures are consistent, that is, the unfolding lengths of the two groups of unfolding structures are consistent, thereby improving the unfolding effect of the MABR membrane arranged thereon (if the unfolding lengths of the two groups of unfolding structures are inconsistent, the MABR membrane arranged on the two groups of unfolding structures will be subjected to shear force, resulting in the MABR membrane being torn and damaged).

[0035] In one feasible manner, a membrane overlap rod 22 is provided between a plurality of second connecting rods 8 provided on the same side of the hanging plate 3, and both ends of the plurality of membrane overlap rods 22 are rotatably connected to the positions where the head and tail of a plurality of second connecting rods 11 are rotatably connected respectively. The setting of the overlap rod further enhances the overlapping and setting effect of the MABR membrane on the two sets of unfolded structures.

[0036] In one feasible manner, a gantry slide 19 is provided on the inner side of each edge of the hanger plate 3, and both ends of the gantry slide 19 pass through the hanger plate 3 and are slidably connected to the hanger plate 3. Both ends of the gantry slide 19 are provided with vertically spaced baffles 20, and the connecting rod 11 is located between the two vertically spaced baffles 20. When the winch retracts the suspension rope 2 thereon and drives the hanger plate 3 to move upward, the closed end 21 of the gantry slide 19 abuts against the bottom surface of the mounting plate 1, so that the gantry slide 19 has a downward movement torque, which is transmitted to the connecting rod 11 through the baffle 20, that is, the connecting rod 11 will be pressed against the lower end of the mounting seat 4, thereby ensuring the contraction effect of the unfolding structure, and avoiding the problem that the spring 10 is subjected to torque due to water surface fluctuations, resulting in continuous sliding and resetting of the slider 9 in the mounting seat 4, causing the unfolding structure to continuously expand and contract, and causing the stability of the entire device moving on the water surface to be affected.

[0037] In one feasible manner, a telescopic rod 24 is provided between the mounting plate 1 and the hanging plate 3, and the two ends of the telescopic rod 24 are respectively fixed to the middle of the hanging plate 3 and the mounting plate 1, and the sling 2 is located inside the telescopic rod 24. The setting of the telescopic rod 24 can connect the hanging plate 3 and the mounting plate 1 as a whole, thereby improving the stability of the unfolding mechanism working underwater. With the setting of the telescopic rod 24, the hanging plate 3 and the mounting plate 1 move as a whole. If the telescopic rod 24 is not provided and only the sling 2 is used for connection, the hanging plate 3 is very likely to swing underwater, thereby affecting the underwater cleaning work.

[0038] In an implementable manner, the telescopic rod 24 includes a number of telescopically sleeved telescopic rod 24 units, which can be understood as the setting method of a fishing rod, that is, the telescopic rod 24 can be composed of a number of sleeved sliding rods. In order to prevent the sliding rods from rotating relative to each other, two adjacent sliding rods are defined as a telescopic unit. That is, the telescopic rod 24 unit includes an outer sliding rod 16 and an inner sliding rod 15 that are telescopically sleeved. A rectangular slideway 17 is provided in the length direction of the outer sliding rod 16, and a stop block 18 is provided on the outer side surface of the inner sliding rod 15. The stop block 18 is located within the rectangular slideway 17. The advantage of this setting method is that the adjacent sliding rods will not rotate relative to each other, and thus the suspension plate 3 and the mounting plate 1 will not rotate relative to each other, thereby avoiding the problem that the suspension plate 3 rotates and causes components such as the air supply pipe 14 provided thereon to become entangled. It is not difficult to understand that in this telescopic setting method, the more the number of sliding rods provided, the closer the distance between the suspension plate 3 and the mounting plate 1 when the suspension plate 3 rises, and the overall height can be further reduced, improving the convenience of the overall movement on the water surface.

[0039] In an implementable manner, a ranging sensor is provided on the lower surface of the suspension plate 3. The ranging sensor is used to detect the distance between the suspension plate 3 and the riverbed. The ranging sensor is electrically connected to the hoist. Through the ranging sensor, the distance between the end of the suspension plate 3 and the riverbed is measured. When the measured distance is less than a preset threshold, the ranging sensor sends a signal to the hoist to control the suspension rope 2 to retract a certain length, thereby driving the entire suspension plate 3 to rise a certain distance, avoiding the situation where the deployment structure touches the bottom mud of the riverbed. Of course, when the measured distance is greater than the preset threshold, the hoist controls the suspension plate 3 to descend to a specified height. It is not difficult to understand that the working premise of the ranging sensor is that this deployment structure is used to act on the bottom mud of the water body, because if the depth of the river channel is large and the upper layer of the water body is acted on and processed, there will be no situation of touching the bottom. The setting of the ranging sensor can avoid the problem that when the hoist lowers the deployment structure, it touches the bottom mud and affects the MABR membrane.

[0040] It is not difficult to understand that the model, working principle, and setting method of the ranging sensor are prior arts, and how to control the operation of the hoist through the ranging sensor is also prior art, and will not be elaborated here too much.

[0041] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
