Description

Technical Field

[0001] The invention belongs to the technical field of water environment treatment, and in particular relates to an automatic liquid level control system for a horizontal flow artificial wetland. Background Art

[0002] Horizontal flow artificial wetland technology is a water environment treatment technology that simulates the natural wetland system and purifies the tailwater of rivers and sewage treatment plants under the synergistic effect of specific substrates, plants and microorganisms. It has the characteristics of low investment, short construction period, low operating cost, good sewage treatment effect, and beautification of the landscape environment. It is applied to the treatment of black and smelly rivers and the ecological restoration of water environment, and has great promotion value.

[0003] In the cold northwest region, due to the alternation of seasons, it is necessary to increase the liquid level of artificial wetlands in winter to form an ice cover insulation layer on the surface of artificial wetlands to ensure the insulation performance of artificial wetland systems and improve the sewage purification effect. However, at present, most artificial wetlands are regulated in a relatively extensive manner, and the liquid level of artificial wetlands cannot be adjusted in time, resulting in the inability to stably form an ice cover insulation layer.

[0004] The horizontal flow artificial wetland system needs to adjust the artificial wetland liquid level in time according to the upstream water situation to achieve the effect of root control and seedling cultivation. However, most artificial wetlands are currently regulated in a relatively extensive manner, and the artificial wetland liquid level cannot be adjusted accurately in time. When the liquid level is too high, the artificial wetland produces a too thick aerated zone. When the liquid level is too low, the treatment effect cannot be achieved. If the liquid level is adjusted too slowly, the wetland plants cannot be controlled for root control and seedling cultivation. Summary of the invention

[0005] In order to solve the deficiencies in the liquid level control of the above-mentioned horizontal flow wetland system, the present invention provides a horizontal flow artificial wetland automatic liquid level control system to solve the real-time and precision of the liquid level control of the horizontal flow artificial wetland.

[0006] The present invention provides a horizontal flow artificial wetland automatic control liquid level system, comprising: a water storage tank, which is connected with the artificial wetland and is used to store the discharged water of the artificial wetland and is equal to the liquid level of the artificial wetland; a liquid level regulating mechanism, comprising a liquid separation component which is arranged in the water storage tank and divides the water storage tank into two horizontal parts, and a control unit which controls the height change of the liquid separation component; a drain pipe which is arranged on the side wall of the water storage tank and is located on the side of the liquid separation component away from the artificial wetland.

[0007] Furthermore, the liquid separation component includes a plurality of rotating liquid plates connected end to end from bottom to top; the control unit is connected to the rotating liquid plates to drive the deflection of the rotating liquid plates.

[0008] Furthermore, the rotating liquid plate includes a liquid plate body, an upper fold edge arranged on the upper side of the liquid plate body, and a lower fold edge arranged on the lower side of the liquid plate body, the upper fold edge and the lower fold edge have opposite bending directions, and the lower side of the upper fold edge of the rotating liquid plate is connected to the upper side of the lower fold edge of the adjacent rotating liquid plate.

[0009] Furthermore, the rotating liquid plate also includes a rotating central shaft which is arranged on the liquid plate body and can drive the rotating liquid plate to deflect, and gear teeth which are sleeved on the rotating central shaft.

[0010] Furthermore, the control unit includes a transmission rod meshed with the gear teeth of the rotating liquid plate and a driving assembly controlling the transmission rod to move up and down to drive the rotating liquid plate to deflect.

[0011] Furthermore, the liquid separation component also includes a base arranged at the bottom of the water storage tank, and the base is connected to the lower folded edge of the adjacent rotating liquid plate.

[0012] Furthermore, the rotating liquid plate includes two gear teeth arranged on both sides of the liquid plate body; the driving mechanism includes two transmission rods respectively meshed with the two gear teeth, and the two transmission rods are respectively in contact with the inner wall of the water storage tank.

[0013] Furthermore, a tooth groove meshing with the gear teeth is provided at the lower end of the transmission rod. When the transmission rod moves up and down to drive the rotating liquid plate meshing with it to deflect, the rotating liquid plate can drive the rotating liquid plate adjacent to it to deflect to change the height of the liquid separation assembly.

[0014] Furthermore, the rotating liquid plate also includes a sealing strip arranged on the lower side of the upper folding edge and a sealing strip arranged on the upper side of the lower folding edge.

[0015] Furthermore, it also includes an outlet pipe arranged on the side wall of the water storage tank and used to communicate with the artificial wetland; the outlet pipe and the drain pipe are both arranged at the lower end of the water storage tank.

The water tank is divided into two independent parts by a liquid separation component. The water outlet pipe is arranged on the side of the liquid separation component away from the artificial wetland. The liquid level of the water tank is adjusted by changing the height of the liquid separation component. Since the liquid levels of the water tank and the artificial wetland are equal, the precise adjustment of the liquid level of the artificial wetland is finally achieved. The liquid level control system of the present invention has the characteristics of simple operation, convenient use, high liquid level adjustment accuracy, etc., and is suitable for popularization and application.

DETAILED DESCRIPTION

[0024] The following embodiments of the technical solution of the present invention are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples, and cannot be used to limit the protection scope of the present invention.

[0025] like Figures 1 to 5 As shown, this embodiment provides a horizontal flow artificial wetland automatic liquid level control system, including: a water storage tank 1, which is connected to the artificial wetland and is used to store the discharged water of the artificial wetland and is equal to the liquid level of the artificial wetland; a liquid level regulating mechanism 2, including a liquid separation component 201 arranged in the water storage tank 1 and dividing the water storage tank 1 into two horizontal parts, and a control unit 202 for controlling the height change of the liquid separation component 201; a drain pipe 3, which is arranged on the side wall of the water storage tank 1 and is located on the side of the liquid separation component 201 away from the artificial wetland.

[0026] In this embodiment, the water discharged from the artificial wetland is stored in the water storage tank 1, and the water storage tank 1 is divided into two independent parts by the liquid separation component 201, namely, the first water storage area 101 close to the artificial wetland side and the second water storage area 102 away from the artificial wetland side. The outlet pipe 4 is arranged in the second water storage area 102 on the side of the liquid separation component 201 away from the artificial wetland. The first water storage area 101 is connected to the artificial wetland to ensure the level of the liquid level. Therefore, when the liquid level of the artificial wetland needs to be adjusted, the height of the liquid separation component 201, that is, the liquid level of the first water storage area 101, is changed to achieve precise adjustment of the liquid level of the artificial wetland. Specifically, when the liquid level of the artificial wetland is too high, the height of the liquid separation component 201 is lowered to the ideal target value. At this time, the water in the first water storage area 101 flows to the second water storage area 102, and the water in the artificial wetland flows to the first water storage area 101 until the liquid level drops to the height of the liquid separation component 201. Similarly, when the liquid level of the artificial wetland is too low, the height of the liquid separation component 201 is raised to the ideal target value. As the upstream water is replenished into the artificial wetland to gradually increase the liquid level, the liquid level of the first water storage area 101 also gradually rises to the target liquid level.

[0027] The horizontal flow artificial wetland automatic liquid level control system provided in this embodiment also includes an outlet pipe 4 arranged on the side wall of the water storage tank 1 and used to connect the artificial wetland; the outlet pipe 4 and the drain pipe 3 are both arranged at the lower end of the water storage tank 1. The outlet pipe 4 is arranged at the lower end of the water storage tank 1, and the liquid level of the artificial wetland and the first water storage area 101 is equal under the same atmospheric pressure by using the U-shaped pipe principle; the drain pipe 3 is arranged at the lower end of the water storage tank 1, which is conducive to the discharge of water in the second water storage area 102.

[0028] In this embodiment, the liquid separation component 201 includes a plurality of rotating liquid plates 211 connected end to end from bottom to top; the control unit 202 is connected to the rotating liquid plates 211 to drive the deflection of the rotating liquid plates 211. The height of the liquid separation component 201 is adjusted by driving the deflection of the rotating liquid plates 211 by the control unit 202, which has the characteristics of simple operation, convenient use, high height adjustment accuracy, etc.

[0029] In a specific embodiment, the rotating liquid plate 211 includes a liquid plate body 2111, an upper fold 2112 disposed on the upper side of the liquid plate body 2111, and a lower fold 2113 disposed on the lower side of the liquid plate body 2111. The upper fold 2112 and the lower fold 2113 are bent in opposite directions, and the lower side of the upper fold 2112 of the rotating liquid plate 211 is connected to the upper side of the lower fold 2113 of the adjacent rotating liquid plate 211. The upper fold 2112 of the rotating liquid plate 211 is connected to the lower fold 2113 of the adjacent rotating liquid plate 211 by buckling, thereby ensuring the sealing between the adjacent rotating liquid plates.

[0030] In a preferred embodiment, the rotating liquid plate 211 also includes a sealing strip 2116 disposed on the lower side of the upper fold 2112 and a sealing strip 2116 disposed on the upper side of the lower fold 2113. By respectively disposing the sealing strips 2116 on the upper fold 2112 and the lower fold 2113, the sealing performance of the upper fold 2112 of the rotating liquid plate 211 and the lower fold 2113 of the adjacent rotating liquid plate 211 is effectively guaranteed, and the rotating liquid plate is guaranteed to be watertight, thereby ensuring the sealing performance of the first liquid storage area, and avoiding the problem that the water in the first liquid storage area flows into the second liquid storage area through the gap of the liquid separation component 201. In a preferred embodiment, the sealing strip is a waterproof sealing strip, such as a rubber sealing ring.

[0031] In this embodiment, the liquid separation component 201 further includes a base 212 disposed at the bottom of the water storage tank 1, and the base 212 is connected to the lower fold 2113 of the adjacent rotating liquid plate 211. By providing the base 212, the rotating liquid plate 211 is fixedly installed, which effectively ensures the installation stability of the liquid separation component 201.

[0032] In this embodiment, the rotating liquid plate 211 also includes a rotating central axis 2114 disposed on the liquid plate body 2111 and capable of driving the rotating liquid plate 211 to deflect, and a gear 2115 sleeved on the rotating central axis 2114. The control unit 202 includes a transmission rod 221 meshed with the gear 2115 of the rotating liquid plate 211 and a driving assembly 222 that controls the transmission rod 221 to move up and down to drive the rotating liquid plate 211 to deflect. In this embodiment, the driving assembly 222 drives the transmission rod 221 to move up and down, and the up and down movement of the transmission rod 221 drives the rotation of the gear 2115 and then drives the deflection of the rotating liquid plate 211, thereby realizing the regulation of the liquid level of the horizontal flow artificial wetland.

[0033] Specifically, when the transmission rod moves from top to bottom, with the help of the meshing connection between the transmission rod and the rotating liquid plate, each rotating liquid plate is driven to deflect in turn. When the top rotating liquid plate deflects, a gap is generated between the first rotating liquid plate and the second rotating liquid plate. At this time, the height of the second rotating liquid plate determines the liquid level; similarly, when the transmission rod drives the second rotating liquid plate to deflect, the first rotating liquid plate is sealed and connected to the second rotating liquid plate, and there is a gap between the second rotating liquid plate and the third rotating liquid plate. At this time, the height of the third rotating liquid plate determines the liquid level. , as the transmission rod moves from top to bottom, the liquid level gradually decreases; when the transmission rod moves from bottom to top, with the meshing connection between the transmission rod and the rotating liquid plate, each rotating liquid plate is driven to deflect in turn. When the lowest rotating liquid plate (non-fixed rotating liquid plate) deflects, a gap is generated between the rotating liquid plate and its adjacent upper rotating liquid plate. At this time, the height of the rotating liquid plate determines the liquid level. When the transmission rod continues to move upward and drives the adjacent upper rotating liquid plate to deflect, the liquid level rises by the height of a rotating liquid plate. As the transmission rod continues to move upward, the liquid level gradually rises. The meshing connection mode between the transmission rod 221 and the rotating liquid plate 211 effectively ensures the accuracy of the height adjustment of the liquid separation component 201, which helps to improve the water purification treatment effect of the horizontal flow artificial wetland.

[0034] In a preferred embodiment, the rotating liquid plate 211 includes two gear teeth 2115 disposed on both sides of the liquid plate body 2111; the driving mechanism includes two transmission rods 221 respectively meshed with the two gear teeth 2115, and the two transmission rods 221 are respectively fitted with the inner wall of the water storage tank 1. By respectively arranging two gear teeth 2115 on both sides of the rotating liquid plate 211, and the two transmission rods 221 are respectively meshed with the two gears, the balance of the deflection of the rotating liquid plate 211 is effectively ensured.

[0035] In a preferred embodiment, the lower end of the transmission rod 221 is provided with a tooth groove 223 meshing with the gear teeth 2115. When the transmission rod 221 moves up and down to drive the rotating liquid plate 211 meshing therewith to deflect, the rotating liquid plate 211 can drive the rotating liquid plate 211 adjacent thereto to deflect, so as to change the height of the liquid separation component 201. In this embodiment, the tooth groove 223 meshing with the gear teeth 2115 is provided at the lower end of the transmission rod 221, so that the rotating liquid plate 211 at the lower end of the liquid separation component 201 is meshed with the transmission rod 221, thereby driving all the rotating liquid plates 211 to deflect.

[0036] In a specific embodiment, the effluent from the horizontal flow artificial wetland enters the water storage tank 1 through the wetland outlet pipe 4, and the driving component 222 controls the transmission rod 221 to descend. When the transmission rod 221 descends, the tooth groove 223 on the transmission rod 221 drives the rotating central axis 2114 to rotate, and the rotation of the rotating central axis 2114 drives the rotating liquid plate 211 to flip, and the liquid level of the wetland water storage tank 1 drops. Finally, the effluent from the horizontal flow artificial wetland is discharged through the drain pipe 3.

[0037] The horizontal flow artificial wetland effluent enters the wetland water storage tank 1 through the wetland outlet pipe 4, and the driving component 222 controls the transmission rod 221 to rise. When the transmission rod 221 rises, the tooth grooves 223 on the transmission rod 221 drive the rotating central axis 2114 to rotate from bottom to top in sequence. The rotation of the rotating central axis 2114 drives the rotating liquid plate 211 to flip, and the liquid level of the wetland water storage tank 1 rises. Finally, the horizontal flow artificial wetland effluent is discharged through the drain pipe 3.

[0038] The horizontal flow artificial wetland automatic liquid level control system in this embodiment can realize the regulation of the artificial wetland winter ice cover insulation layer and the root control and seedling cultivation of wetland plants. The thickness of the winter ice cover insulation layer can be adjusted by raising the winter wetland operating liquid level. Since the plant roots grow at the top, the wetland operating liquid level is lowered by the automatic liquid level control system, and the wetland operating liquid level is maintained in the middle and lower parts, inducing the growth of plant roots, thereby accelerating the formation of lateral roots.

[0039] The horizontal flow artificial wetland automatic liquid level system in this embodiment has obvious advantages over the prior art: by regulating the liquid level of the horizontal flow artificial wetland, the problem of heat preservation operation of the horizontal flow artificial wetland system in cold winter and low temperature areas is solved, and the artificial wetland system's ability to purify pollutants in water in winter is improved; by accurately regulating the liquid level of the artificial wetland through the automatic liquid level system, the problems of wetland plant root control and seedling cultivation and wetland liquid level control that are not timely and accurate are solved, the growth of plant roots is accelerated, and the absorption of pollutants in water by plant roots is improved, thereby improving the artificial wetland's ability to purify pollutants in water.
