Large floating pump station for Yizimen Dam and its operation mode

Abstract

The present invention relates to the field of water conservancy projects, specifically to a large floating ship-type pump station for a Yizimen river dam, comprising a foundation, a station body, a stern hinge, a propulsion system, a ballast system, a measurement and control system, and a main pump system. At the same time, an operating mode applied to the present invention is provided. The present invention connects the station body to a U-shaped foundation fixedly installed in a waterway through a stern hinge. When the waterway is blocked, the measurement and control system controls the operation of the propulsion system and the ballast system, and controls the station body to rotate around the axis of the stern hinge, so that the station body intercepts the waterway. Therefore, the structural strength of the present invention is high. Compared with the currently commonly designed small water pump installed on the gate to transport water, the scale of the gate hole and the scale of the water pump that can be applied to the present invention are both increased, and the present invention can be adapted for large-span gate holes and medium and large pump stations.

Description

Technical Field

[0001] The invention relates to the field of water conservancy projects, in particular to a large floating ship type pump station with a straight gate dam and an operation mode thereof. Background Art

[0002] Traditional pump-and-sluice water conservancy hubs generally include at least two components: sluice gates and pumping stations. Sluice gates and pumping stations are generally arranged side by side, and both require width perpendicular to the direction of water flow. When the hub is relatively large, in addition to occupying the area of ​​the waterway, it is often necessary to occupy additional land outside the waterway. When it is necessary to build medium- and large-scale water conservancy hubs in cities, there is often insufficient land area because other facilities are already occupied nearby, which poses great construction difficulties. At the same time, traditional water conservancy hubs all use fixed reinforced concrete structures, requiring the construction of various functional structures such as racks, pump houses, and switch stations. When it is necessary to build medium- and large-scale water conservancy projects in cities, various functional structures are often difficult to match with the city's existing buildings and scenery, affecting the urban landscape.

[0003] In the prior art, in order to solve the above-mentioned problems of large construction area, high construction difficulty and poor aesthetics, small water pumps are often designed to be installed on the gates to transport water, thereby reducing the width and land area occupied by the hub in the direction perpendicular to the water flow.

[0004] However, this technology is still only applicable to small and micro water pump devices so far. The scale of the gate holes and water pumps it can be applied to are very limited, and it is not suitable for use in large-span gate holes and medium and large pumping stations.

[0067] The technical solution of the present invention will be further described in detail below in conjunction with specific implementation methods.

[0068] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 7 As shown, in an embodiment of the present invention, a large floating pump station with a Yizimen dam includes:

[0069] The foundation 1 is installed in the waterway and has a U-shaped structure. Specifically, the foundation 1 used in the present invention adopts a reinforced concrete structure, and is distributed on the riverbed, left bank, and right bank to form a U-shaped structure, which is connected to the natural riverway. When the waterway is opened, water flows through. The foundation 1 supports the station body 2 when the station body 2 is in a sunken state, and also supports the horizontal water pressure transmitted from the station body 2 when the station body 2 is in a water-retaining state.

[0070] The station body 2 is installed on the foundation 1 and is used to block the connection between the water bodies on both sides when closing the waterway. Specifically, the station body 2 is the direct bearing structure of the present invention. When closing the waterway, the station body 2 is located between the left bank structure and the right bank structure of the foundation 1, closing the middle part of the U-shaped structure of the station body 2, and blocking the connection between the water bodies on both sides.

[0071] a stern hinge 3, provided on the outer side of the stern of the stand 2, connecting the stand to the base 1 via the stern hinge 3, and constraining the stand 2 when it moves;

[0072] A propulsion system 5 is provided inside the station body 2 and is used to realize the rotational movement of the station body 2 around the axis of the stern hinge 3;

[0073] The ballast system 4 is provided inside the station body 2 and is used to control the ballast water in the cabin, thereby achieving the vertical lifting of the station body 2;

[0074] The measurement and control system 7 includes sensors and a navigation computer for monitoring and controlling the movement of the station 2 to ensure smooth movement;

[0075] The main pump system 6 is arranged in the main pump flow channel 22 on the station body 2, and is used to drain water from the water body on one side of the station body 2 through the main pump flow channel 22 to the water body on the other side. Water retaining components and water filtering components are respectively installed on both sides of the main pump flow channel 22.

[0076] See Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, in this embodiment of the present invention, the standing body 2 includes:

[0077] The hull structure 21 includes a bottom plate, a port plate, a starboard plate, a bow plate, a transom, a first deck, and a second deck. Beams, longitudinals, and stiffeners are provided behind each of the above structural plates. Multiple transverse and longitudinal partitions are provided within the space enclosed by the above structural plates to separate the interior space of the station 2 into multiple independent, enclosed compartments.

[0078] The main pump flow channel 22 is provided in the lower compartment of the hull structure 21, penetrates the side plate and the partition plate, and is used to form the water inlet and outlet channels of the main pump 61 system;

[0079] The propulsion channel 23 is provided in the lower compartment of the hull structure 21, penetrates the side plate and the bulkhead, and is used to form the water inlet and outlet channels of the propulsion system 5;

[0080] A water-stopping component 24 is provided on the bottom plate and side of the hull structure 21 and is used to seal the gap between the foundation 1 and the hull structure 21 when closing the waterway;

[0081] Furthermore, the various compartments of the hull structure 21 are generally classified into the following types according to their locations and functions:

[0082] The ballast water tanks are located at the lower part of the hull structure 21 and are used to store ballast water. Each ballast water tank is independent of each other and is connected to the outside world and each other through the ballast system 4;

[0083] The engine room, located in the upper part of the hull structure 21, is where various components of various systems, circuit pipelines, water pipelines, oil pipelines, gas pipelines, cabinets and other components are installed. It is also the inspection and maintenance space for operators and maintenance personnel;

[0084] The propeller valve compartment is located near the bow of the hull structure 21 and runs vertically from the first deck to the bottom plate. It is the installation location of the propulsion system 5.

[0085] The main pump 61 compartment is provided with multiple ones and is located on the longitudinal axis of the hull structure 21, vertically passing from the first deck to the bottom plate, and is the installation location of the main pump system 6;

[0086] For further information, see Figure 1 and Figure 6 As shown, the stern hinge 3 includes a hinge seat 31, a hinge shaft 32, a hinge head 33 and a bearing 34, wherein the hinge seat 31 and the hinge shaft 32 are fixedly connected to the base 1, the hinge head 33 is fixedly connected to the stand 2, the hinge shaft 32 has sufficient length in the vertical direction to allow the stand 2 to move in the vertical direction, and the bearing 34 and the hinge shaft 32 are not tightly fitted, but there is a certain gap between them to allow slight deviation of the stand 2 in movement.

[0087] like Figure 5 As shown, in the embodiment of the present invention, the main pump system 6 includes:

[0088] The main pump 61 is installed in the lower compartment of the station body 2, horizontally positioned on the longitudinal axis of the station body 2 and aligned with the main pump flow channel 22. The main pump 61 is detachably connected to the station body 2. The main pump 61 can slide up and down along a track and can be hoisted into and out of position using a lifting device. It uses a wet stator, full-flow submersible pump, which reduces the length and width of the pump, thereby reducing the size of the station body 2.

[0089] The water-blocking component is a flap door assembly 63, which is fixedly mounted on the outside of the station body 2 facing the water inlet side of the waterway, aligned with the main pump flow channel 22, and is used to control the opening and closing of the main pump flow channel 22;

[0090] The water filtering component is a gate assembly 62 , which is fixedly mounted on the outside of the side plate of the station body 2 which is different from the side plate where the flap gate assembly 63 is mounted, and is aligned with the main pump flow channel 22 .

[0091] like Figure 10 As shown, in the embodiment of the present invention, the flap door assembly 63 includes:

[0092] The door frame I 631 is fixedly connected to the station body 2;

[0093] The flap door seat 632 is connected to the door frame I 631 in an up-and-down sliding manner and can be lifted into and out of the original position by a lifting device;

[0094] The flap door leaf 633 is hingedly connected to the flap door seat 632 and is installed in pairs on a flap door seat 632. The flap door leaf 633 is opened in a split-type manner, and the main pump flow channel 22 is opened and closed by rotating a pair of flap door leaves 633.

[0095] like Figure 8 and Figure 9 As shown, in the embodiment of the present invention, the gate assembly 62 includes:

[0096] Door frame II 621 is fixedly connected to the station body 2;

[0097] Trash rack 622, fixedly connected to door frame II 621, is used to block debris in the water when the main pump 61 is pumping water;

[0098] The emergency door 623 is connected to the door frame II 621 in an upward and downward sliding manner, can be hoisted into and out of the original position by a hoisting device, and is fixedly connected to the station body 2 by an upper lock 624;

[0099] When the main pump 61 starts, water flows from one side of the station body 2, through the gate assembly 62, the main pump 61, and the flap door assembly 63, to the other side of the station body 2. The trash rack 622 filters out debris from the water, allowing clean water to flow through the main pump 61 to prevent damage. The main pump 61 provides power for drainage, and the flap door assembly 63 acts as a one-way valve to prevent water from flowing in the opposite direction. When the main pump 61 starts, the flap door assembly 63 will only activate when the pressure behind the pump exceeds the external water pressure, preventing the main pump 61 from starting under pressure. When the main pump 61 stops, the flap door assembly 63 will promptly close the flow channel to prevent the main pump 61 from reversing. If the main pump 61 fails and the flap door assembly 63 also fails and cannot close the flow channel, the emergency door 623 will immediately drop, cutting off the water flow, effectively preventing further escalation of the accident.

[0100] like Figure 1 As shown, in the embodiment of the present invention, the foundation 1 is further provided with a gate structure on one side of the waterway, which is used to accommodate the stand 2 when the waterway is opened. The stand 2 is located in the gate of the foundation 1 when the waterway is opened, and is located between the left bank structure and the right bank structure of the foundation 1 when the waterway is closed, closing the middle part of the U-shaped structure and blocking the connection between the water bodies on both sides.

[0101] like Figure 7 As shown, in the embodiment of the present invention, see Figure 7As shown, the ballast system 4 is located in the upper compartment of the station body 2 and is used to transport ballast water to the lower compartment of the station body 2. The ballast system 4 includes main components such as a ballast water pump, a valve 52, and pipes, as well as other necessary components. The main components are installed in the upper compartment of the station body 2, and the water body controlled by the ballast system is located in the lower compartment of the station body 2. The compartments storing ballast water are independently controlled to accurately control the total mass and mass distribution of the station body 2 when it moves in the water, thereby achieving the sinking and floating movement of the station body 2 and the posture control during movement.

[0102] like Figure 2 、 Figure 3 as well as Figure 4 As shown, in the embodiment of the present invention, the propulsion system 5 is installed in the propulsion flow channel 23 on the side of the station body 2 away from the stern hinge 3, and includes a propeller 51 and a valve 52, which are installed inside the station body 2 near the bow and aligned with the propulsion flow channel 23. The propeller 51 adopts a bidirectional blade, which can propel both forward and reverse, thereby allowing the station body 2 to rotate both clockwise and counterclockwise. The valve 52 is connected in series with the propeller 51 and is used to close the propulsion flow channel 23 when the station body 2 blocks water;

[0103] Further, such as Figure 11 As shown, instead of using a propeller 51 and valve 52 in the propulsion system 5, a winch 8 can be used instead. In this embodiment, a fixed winch 8 is installed on each side of the river bank. The winch 8 outputs a horizontal rope, and the lifting head is connected to the bow of the station body 2. When the waterway needs to be closed, the winch 8 on the opposite bank of the gate is activated, pulling the station body 2 toward itself, and the winch 8 on the same bank of the gate is driven. When the waterway needs to be opened, the winch 8 on the same bank of the gate is activated, pulling the station body 2 toward itself, and the winch 8 on the opposite bank of the gate is driven.

[0104] Further, if Figure 12 As shown, a hydraulic cylinder 9 is used to replace the propeller 51 and valve 52 structure. In this embodiment, two sets of hydraulic cylinders 9 are provided on the foundation 1 near the stern hinge 3. The hydraulic cylinders 9 swing greatly in the horizontal position and can swing slightly in the vertical position. The cylinder heads are connected to the station body 2. When the waterway needs to be closed, one cylinder generates thrust and the other generates pulling force, which jointly push the station body 2; when the waterway needs to be opened, the pushing and pulling of the two cylinders are opposite. Compared with using only one cylinder, using two cylinders can avoid the situation where the force arm is too small at a certain movement position, which makes it difficult to push or even leads to a dead point in movement.

[0105] Further, if Figure 13As shown, a retractable propeller 10 is used. If the design conditions are slightly different, the body 2 will need to float higher during rotation, causing the original design's propulsion channel to be too close to the water surface or even above it, making it difficult for the propeller 51 to generate power. Using a retractable propeller 51 can solve this problem.

[0106] See Figure 14 As shown, the main pump 61 of the main pump system 6 does not adopt a wet stator full-flow submersible pump, but a vertical submersible submersible pump 11. At the same time, the design of the main pump flow channel 22 is slightly different from that of the first embodiment.

[0107] See Figure 15 As shown, the main pump system 6 does not utilize a combination of a main pump 61, a gate assembly 62, and a flapper assembly 63. Instead, it utilizes a full-flow pump and a rapid valve 52. The main pump 61 and valve 52 are integrated into a single unit, known as a pump-valve assembly, which performs both drainage and water retention functions. By eliminating the gate assembly 62 and flapper assembly 63, the sides of the hull 2 ​​are free of attachments, reducing obstruction and disruption to the water flow. This benefits the hull structure 21 and enhances its stability.

[0108] At the same time, the present invention also provides an operation method of a large floating pump station with a straight gate dam;

[0109] 1. When the waterway is intercepted by station 2 to control water transportation, the operation steps are as follows:

[0110] In the stopped state, the floating pump station is docked in the bank gate. Upon receiving the command, the ballast system 4 discharges the ballast water in the cabin into the river, the total mass of the station body 2 is reduced, and the station body 2 floats up and enters the floating state.

[0111] Step S2: The station 2 is in a floating state and begins to perform attitude control. The monitoring and control system monitors the water level, water flow velocity, water flow pressure, water flow state, spatial position of the station 2, spatial attitude of the station 2, movement speed of the station 2, movement acceleration of the station 2, total mass of the station 2, and mass distribution of the station 2 in real time. The monitoring and control system continuously sends adjustment instructions to the propulsion system 5 and the ballast system 4 to continuously change the thrust size, thrust direction, total ballast water amount, and ballast water distribution.

[0112] Step S3: The station body 2 begins to rotate around the axis of the stern hinge 3. Under the combined action of the water flow and the propulsion system 5, the station moves from the shore position to the water retaining position. During this process, the posture control is continuously in effect.

[0113] Step S4: After reaching the water retaining position, the ballast system 4 draws the river water into the cabin, the total mass of the station body 2 increases, and the station body 2 sinks until it reaches the river bottom, and the posture control ends;

[0114] Step S5: the main pump 61 is started and enters the running state, pumping the water on one side of the station body 2 to the other side, and the floating pump station enters the pumping state.

[0115] 2. When the drive station 2 is reset and the waterway is restored to normal operation, the operation steps are as follows:

[0116] Step S1: Under the pumping condition, the floating pump station is located at the water blocking position, the main pump 61 is in operation, and upon receiving a command, the main pump 61 stops running;

[0117] Step S2: The ballast system 4 discharges the ballast water in the cabin into the river, the total mass of the station body 2 is reduced, and the station body 2 floats up and enters a floating state;

[0118] Step S3: The station 2 is in a floating state and begins to perform attitude control. The monitoring and control system monitors the water level, water flow velocity, water flow pressure, water flow state, spatial position of the station 2, spatial attitude of the station 2, movement speed of the station 2, movement acceleration of the station 2, total mass of the station 2, and mass distribution of the station 2 in real time. The monitoring and control system continuously sends adjustment instructions to the propulsion system 5 and the ballast system 4 to continuously change the thrust size, thrust direction, total ballast water amount, and ballast water distribution.

[0119] Step S4: the station body 2 begins to rotate around the axis of the stern hinge 3, and under the combined action of the water flow and the propulsion system 5, it moves from the water-blocking position to the shore position; during this process, the posture control continues to function;

[0120] Step S5: After reaching the gate position, the ballast system 4 sucks the river water into the cabin, the total mass of the station body 2 increases, the station body 2 sinks until it reaches the river bottom, the posture control ends, and the floating pump station enters the stop state.

[0121] In summary, the present invention provides a complete solution for building a pump station type water conservancy hub that effectively adapts to the urban environment, and the subsystems can be adjusted according to different actual conditions to adapt.

[0122] Compared with traditional water conservancy hubs, the station body 2 of the present invention is usually docked in the gate warehouse, which reduces the floor space required for the water conservancy hub and solves the biggest difficulty in the construction of large-scale water conservancy projects in cities;

[0123] Compared with traditional water conservancy hubs, the present invention requires less civil engineering and less demolition, thus reducing the project cost.

[0124] During construction, the station body 2 and all supporting systems of the present invention can be built in the dock and then floated to the construction site, which greatly shortens the on-site working hours.

[0125] During maintenance, the station of the present invention can be floated to the dock for inspection and repair, eliminating the need to construct additional cofferdams or inspection gates at the project site to create a dry land environment, thereby reducing maintenance costs and preserving the landscape during the maintenance period.

[0126] The pump station of the present invention has no buildings above the ground, and has a good landscape effect, and is particularly suitable for use in scenes with high requirements on appearance, such as cities;

[0127] When the present invention is used in a comprehensive water conservancy hub, the station body 2 can also serve as a sluice, achieving multiple functions with one facility;

[0128] Compared with the existing gate pump technology, the present invention has a wider scope of application and is suitable for large-span waterways and gate holes, and for medium and large pump station-type water conservancy hubs.

[0129] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0130] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in this field without departing from the purpose of the present invention.
