[0011] A peristaltic sewage discharge mechanism is arranged in the installation chamber, and the support mechanism passes through the upper and lower surfaces to define an installation gap. The peristaltic sewage discharge mechanism passes through the installation gap and is slidably connected to the bottom surface of the flexible water bag between a first position and a second position. When the peristaltic sewage discharge mechanism moves from the first position to the second position, the peristaltic sewage discharge mechanism can lift the bottom surface of the flexible water bag upward, causing the bottom surface of the flexible water bag to peristalsize toward the sewage trough, and the sludge is discharged from the bottom surface of the flexible water bag into the sewage trough.

[0012] Furthermore, the bottom of the sewage trough is fixedly arranged in the installation chamber through a column, and a screw conveyor is arranged in the sewage trough.

[0032] 2. The present invention uses a flexible water bag, which has the following advantages:

[0034] The flexible water bag deforms under the drive of the peristaltic mechanism, which can exert dynamic shear force on the sludge and destroy the adhesion structure of the sludge. The deformation of the flexible material can reduce the contact area with the sludge and reduce the adhesion. In an environment with reduced sludge viscosity, the sludge is gradually pushed towards the sewage trough by peristalsis and then pushed into the sewage trough.

[0035] 3. The present invention is also coupled with a high-pressure water jet mechanism. On the basis of the peristaltic sewage discharge mechanism, the high-pressure water jet mechanism can further reduce the viscosity of the sludge, thereby greatly improving the cleaning efficiency; in addition, the high-pressure water jet mechanism can also be used to directly clean the sludge located on the inner wall of the water reservoir. The viscosity of the sludge at this location is relatively low, and it can be flushed to the bottom of the water reservoir through the high-pressure water jet mechanism, and pushed to the sewage trough together with the peristaltic sewage discharge mechanism.

[0036] 4. The present invention provides a sludge thickness sensor in the reservoir to monitor the sludge thickness and clean the sludge in time to avoid blockage. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0047] Among the prior arts that have been searched:

[0048] Patent CN113026920B discloses a water storage device for mine ecological restoration, which aims to solve the problem that water storage devices in existing mine ecological restoration are prone to fouling and cannot effectively discharge sewage. It has the characteristics of simple structure, easy use, self-cleaning and sewage discharge.

[0049] The water storage device mainly consists of the following parts:

[0050] Water storage tank: There is a water storage chamber inside, which is connected to the outside through the water inlet hole.

[0051] Sewage discharge mechanism: includes a sewage trough, a sewage pipe, a guide vane and a first driving mechanism. The guide vane is driven by a worm gear and a pulley to guide the sludge to the sewage trough, and then pushed to the sewage pipe by the spiral rod, and finally discharged by the water pump.

[0052] Protection mechanism: It consists of a protection plate and an extension plate, floating on the water surface, covering the entire water surface to prevent impurities from falling into the water. There is an air cushion at the bottom of the protection plate and an air bag at the bottom of the extension plate. The two are connected by an elastic mechanism and can be freely extended and retracted according to the height of the water surface.

[0053] Cleaning mechanism: including cleaning roller, third driving mechanism and fourth driving mechanism. The cleaning roller can rotate and move along the side wall of the water storage chamber to clean the dirt on the inner wall.

[0054] How it works

[0055] Sewage discharge process: The first drive mechanism drives the worm to rotate, the worm drives the worm wheel, and the guide vane rotates through the pulley and belt transmission to guide the sludge to the sewage tank. The spiral rod is driven by the second drive mechanism to push the sludge to the sewage pipe, and finally discharged by the water pump.

[0056] Protection process: The protection board floats on the water surface, and the extension board freely expands and contracts according to the water surface height, covering the entire water surface to prevent impurities from falling into the water.

[0057] Cleaning process: The third driving mechanism drives the cleaning roller to rotate, and the fourth driving mechanism enables the cleaning roller to move up and down along the side wall of the water storage chamber through the lead screw to achieve comprehensive cleaning of the inner wall.

[0058] The device uses guide vanes to guide the sludge on the bottom of the water tank to treat the sludge. The guide vanes will generate vortexes during rotation, and relative flows will also be generated between the guide vanes on both sides of the trough. In this case, the sludge will spread over a large area and form a suspension in the water tank, making it difficult for the sludge to enter the trough. In addition, due to the viscosity of the sludge, it is difficult to completely remove the sludge on the bottom of the water tank only by the rotation of the guide vanes.

[0059] 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.

[0060] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0061] Example 1

[0062] The embodiment of the present invention provides a mine ecological restoration water storage device, comprising:

[0063] A water reservoir 1 having an inner wall and a lower opening;

[0064] An installation chamber 2 is arranged below the lower opening and communicated with the lower opening;

[0065] A sewage chute 3 is provided at the lower opening along the length direction of the water storage tank 1;

[0066] The flexible water bag 4 is made of high-strength PVC or rubber, adapted to the shape of the water reservoir 1 and arranged on the left and right sides of the sewage trough 3; the side surface 401 of the flexible water bag 4 is fixedly connected to the inner side wall of the water reservoir 1, and the bottom surface 402 of the flexible water bag 4 is arranged at the lower opening and connected to the upper edge of the sewage trough 3;

[0067] A supporting mechanism is disposed at the lower opening and fixedly mounted on the mounting chamber 2, and the supporting mechanism is used to support the bottom surface 402 of the flexible water bag 4;

[0068] The peristaltic sewage discharge mechanism is arranged in the installation chamber 2, and the supporting mechanism passes through the upper and lower surfaces to define an installation gap 5. The peristaltic sewage discharge mechanism passes through the installation gap 5 and is slidably connected with the bottom surface 402 of the flexible water bag 4 between a first position and a second position. When the peristaltic sewage discharge mechanism moves from the first position to the second position, the peristaltic sewage discharge mechanism can lift the bottom surface 402 of the flexible water bag 4 upward, so that the bottom surface 402 of the flexible water bag 4 peristalses toward the sewage trough 3, and the sludge is discharged from the bottom surface 402 of the flexible water bag 4 into the sewage trough 3.

[0069] In this embodiment, the bottom of the sewage trough 3 is fixedly disposed in the installation chamber 2 via a column 6 , and a screw conveyor is disposed in the sewage trough 3 .

[0070] In this embodiment, the support mechanism is composed of a plurality of support plates 7 and support columns 8. The drain trough 3 is arranged along the Y-axis direction, and the support plates 7 are arranged on the left and right sides of the drain trough 3 along the X-axis direction. The upper surface of the support plate 7 is connected to the bottom surface 402 of the flexible water bag 4. The support column 8 is vertically arranged in the installation chamber 2 and connected to the lower surface of the support plate 7. An installation gap 5 is defined between adjacent support plates 7 along the X-axis direction.

[0071] In this embodiment, the peristaltic sewage discharge mechanism includes:

[0072] The sliding base 9 is slidably connected to the bottom surface 402 of the installation chamber 2 along the X-axis direction. The sliding base 9 is fixedly connected to the output end of the telescopic motor 10. The telescopic motor 10 is arranged in the installation chamber 2 and can drive the sliding base 9 to move along the X-axis direction.

[0073] The push rod 13 assembly is arranged on the sliding base 9. The push rod 13 assembly passes through the installation gap 5 and is slidably connected to the bottom surface 402 of the flexible water bag 4. When the telescopic motor 10 drives the sliding base 9 to move from the first position to the second position, the push rod 13 assembly lifts the bottom surface 402 of the flexible water bag 4 upward, causing the bottom surface 402 of the flexible water bag 4 to creep toward the sewage trough 3, and the sludge is discharged from the bottom surface 402 of the flexible water bag 4 into the sewage trough 3.

[0074] In this embodiment, multiple groups of peristaltic drainage mechanisms are provided (only one group is shown in the figure), and the multiple groups of peristaltic drainage mechanisms move synchronously and in the same direction, which can make the bottom surface 402 of the flexible water bag 4 produce "wave-shaped" periodic movement in the same direction. The multiple groups of peristaltic drainage mechanisms can clean the sludge on the bottom surface 402 of the flexible water bag 4 in a single movement. The number of peristaltic drainage mechanisms can be flexibly set according to the length of the bottom surface 402 of the flexible water bag 4. If it is necessary to ensure that the sludge in the flexible water bag 4 can be completely cleaned in a single movement, the number of peristaltic drainage mechanisms is at least one group per 3 meters.

[0075] In this embodiment, the push rod 13 assembly includes:

[0076] A support 11 is fixedly arranged on the sliding base 9;

[0077] A connecting rod 12 is disposed on the support 11;

[0078] The push rod 13 is a cylindrical structure arranged along the Y-axis. The upper end of the connecting rod 12 passes through the installation gap 5 from bottom to top and is fixedly connected to the push rod 13. The width of the push rod 13 is greater than the width of the installation gap 5. Two adjacent push rods 13 can be arranged close to each other to increase the contact area between the push rod 13 and the bottom surface 402 of the flexible water bag 4. The push rod 13 is slidably connected to the bottom surface 402 of the flexible water bag 4 and can lift the bottom surface 402 of the flexible water bag 4 upward.

[0079] Example 2

[0080] The difference between this embodiment and the first embodiment is that the connecting rod 12 is telescopically arranged on the support 11 in the up-down direction, and the specific telescopic structure can adopt the existing technology, for example, a spring can be arranged at the connection between the connecting rod 12 and the support 11. A through hole 14 is formed between the end of the support plate 7 close to the side 401 of the flexible water bag 4 and the installation chamber 2, and the through hole 14 allows the connecting rod to pass through. At the same time, the support plate 7 is also installed with the shortest length. The installation chamber 2 is hollowed out at the junction of the bottom surface 402 and the side surface 401 of the flexible water bag 4, so as to expand the size of the through hole 14 to ensure the smooth movement of the top rod 13.

[0081] Also includes:

[0082] The directional track 15 is fixedly arranged in the installation chamber 2 along the X-axis direction. The two end heads of the directional track 15 are respectively fixed on the inner wall of the installation chamber 2 and the column 6 below the sewage trough 3. The directional track 15 and the support plate 7 are arranged at intervals up and down. The connecting rod 12 is provided with a mounting hole matched with the directional track 15 along the X-axis direction. The connecting rod 12 is slidably connected with the directional track 15 through the mounting hole; the part of the directional track 15 corresponding to the bottom surface 402 of the flexible water bag 4 is bent upward to form a high horizontal section 1501. When the telescopic motor 10 drives the sliding base 9 to move to the high horizontal section 1501, when the connecting rod 12 moves to the position corresponding to the high horizontal section 1501, the push rod 13 passes through the through hole 14 from bottom to top and lifts the bottom surface 402 of the flexible water bag 4 upward.

[0083] Compared with Example 1, in this embodiment, when there is no need to clean the sludge, the push rod 13 can be moved from the through hole 14 to the installation chamber 2 through the limiting effect of the connecting rod 12 and the directional track 15, without having to always maintain the lifting effect on the bottom surface 402 of the flexible water bag 4 like the push rod 13 in Example 1. Compared with the embodiment, the bottom surface 402 of the flexible water bag 4 is smoother and the service life of the flexible water bag 4 is longer.

[0084] It should be noted that, since the side surface 401 and the bottom surface 402 of the flexible water bag 4 are integrally connected, and the size of the through hole 14 only needs to ensure that the connecting rod can pass through, the provision of the through hole 14 does not affect the overall installation stability of the flexible water bag 4. In addition, to ensure the lifting effect, in this embodiment, when the push rod 13 passes through the through hole 14 upward, it actually slightly lifts the side surface 401 of the flexible water bag 4.

[0085] Example 3

[0086] The difference between this embodiment and embodiment 2 is that it further includes:

[0087] The high-pressure water jet mechanism 16 is disposed in the water reservoir 1 , with its water inlet end being connected to the water reservoir 1 and its water outlet end corresponding to the bottom surface 402 of the flexible water bag 4 .

[0088] In this embodiment, it also includes:

[0089] The water outlet branch 17 is connected to the water outlet end of the high-pressure water jet mechanism 16 and extends to a position close to the side surface 401 of the flexible water bag 4.

[0090] In this embodiment, the bottom surface 402 and the side surface 401 of the flexible water bag 4 are provided with silt thickness sensors, and the silt thickness sensors are used to monitor the silt thickness on the bottom surface 402 and the side surface 401 of the flexible water bag 4 .

[0091] The working process is described below in conjunction with Example 3:

[0092] When the sludge thickness sensor detects that the side 401 and bottom 402 of the flexible water bag 4 reach the preset sludge thickness, the high-pressure water jet mechanism 16 is first started to spray the side 401 and bottom 402 of the flexible water bag 4 with water jets to flush the sludge on the side 401 of the flexible water bag 4 to the bottom of the flexible water bag 4, and at the same time, the viscosity of the sludge at the bottom of the flexible water bag 4 can also be reduced.

[0093] When the water quality in the water reservoir 1 is stable (no turbidity), start the telescopic motor 10, and the telescopic motor 10 drives the sliding base 9 to move from the first position to the second position. When the sliding base 9 moves to the position corresponding to the high horizontal section 1501, the connecting rod 12 is limited by the directional track 15 and moves to the high horizontal section 1501. The top rod 13 passes through the through hole 14 from bottom to top and lifts the bottom surface 402 of the flexible water bag 4 upward. The bottom surface 402 of the flexible water bag 4 bulges upward away from the end of the sewage trough 3.

[0094] The telescopic motor 10 continues to drive the sliding base 9 to move toward the second position, and the raised position of the bottom surface 402 of the flexible water bag 4 gradually approaches the sewage trough 3, thereby generating a peristaltic effect. The sludge on the bottom surface 402 of the flexible water bag 4 moves toward the sewage trough 3 under the action of peristalsis, and finally enters the sewage trough 3, and is pushed to the end of the sewage trough 3 by the screw conveyor in the sewage trough 3 for centralized treatment.

[0095] In the above working process, since the peristaltic action is very gentle and the force is applied from the bottom of the sludge, the sludge will not spread over a large area, the water quality can basically maintain its original state, and no suspension will be produced. The telescopic motor 10 can complete the discharge of the sludge with a single drive.

[0096] The application test data is as follows (Example 3):

[0097] Application scenario 1: Mine reservoir in southern hilly area 1

[0098] Mine reservoirs in the southern hilly areas are mainly used to collect rainwater and surface runoff. However, due to heavy rainfall and high sediment content, silt deposition is serious in the reservoirs, and traditional cleaning methods are inefficient and costly.

[0099] Application Effect

[0100] Cleaning efficiency: ≥95% (traditional method is 70%-80%).

[0101] Cleaning time: ≤20 minutes / time (traditional method is 40 minutes / time).

[0102] Application scenario 2: Mine reservoir in arid areas of Northwest China 1

[0103] Mine reservoirs in the arid northwest region are mainly used to store irrigation water. However, due to strong winds and sand and large evaporation, the silt in the reservoir is dry and highly viscous, making it difficult to completely remove it using traditional cleaning methods.

[0104] Application Effect

[0105] Cleaning efficiency: ≥90% (traditional method is 60%-70%).

[0106] Cleaning time: ≤30 minutes / time (traditional method is 60 minutes / time).

[0107] Application scenario 3: Mine water reservoir in cold northern regions 1

[0108] The mine water reservoirs in the cold northern regions freeze in winter and suffer from severe silt deposition after the ice melts in spring. Traditional cleaning methods are inefficient in low temperature environments.

[0109] Application Effect

[0110] Cleaning efficiency: ≥95% (traditional method is 50%-60%).

[0111] Cleaning time: ≤40 minutes / time (traditional method is 80 minutes / time).

[0112] Application scenario 4: Mine reservoir in the eastern coastal area 1

[0113] Mine reservoirs in the eastern coastal areas are mainly used to collect rainwater and surface runoff. However, due to seawater backflow and salt deposition, the silt in the reservoirs is high in salt and viscosity, making it difficult to completely remove it using traditional cleaning methods.

[0114] Application Effect

[0115] Cleaning efficiency: ≥92% (traditional method is 65%-75%).

[0116] Cleaning time: ≤25 minutes / time (traditional method is 50 minutes / time).

[0117] Application scenario 5: Mine reservoir in the central plains 1

[0118] Mine reservoirs in the central plains are mainly used to collect rainwater and surface runoff. However, due to agricultural non-point source pollution, the organic matter content of the sludge in the reservoir is high, and traditional cleaning methods are inefficient and prone to clogging.

[0119] Application Effect

[0120] Cleaning efficiency: ≥94% (traditional method is 70%-80%).

[0121] Cleaning time: ≤15 minutes / time (traditional method is 30 minutes / time).

[0122] From the above application test data, it can be seen that the cleaning efficiency of the mine ecological restoration water storage device disclosed in this embodiment can reach more than 90% and is much higher than the traditional method. It can be considered that this embodiment can efficiently remove the silt of the water storage device. In addition, this embodiment can also greatly reduce the cleaning time, which has good application prospects and a wide range of applications.
