Description

Technical Field

[0001] This utility model relates to the field of water conservancy technology, and in particular to a water diversion flow regulation device. Background Technology

[0002] Hydraulic diversion and flow regulation devices are key equipment in water conservancy projects used to control and distribute water flow. Their core function is to precisely regulate water flow according to actual needs to meet the application requirements of various scenarios such as irrigation, flood control, water supply, and power generation. In water conservancy facilities such as small and medium-sized reservoirs and irrigation canals, planar gates are used to control the flow of water, regulate water level and flow rate.

[0003] A planar gate is driven by a screw to move the gate plate, thereby controlling the water flow. The screw of the planar gate is usually installed on the back of the gate plate (the back side of the water), which can effectively avoid the direct impact of high-speed water flow on the front side and reduce the erosion and wear of the screw surface by silt particles; at the same time, the relatively stable water flow environment on the back side also reduces the risk of debris entanglement.

[0004] However, even when positioned on the backwater side, the screw cannot completely avoid contact with the water flow during long-term operation. The underwater environment is complex and variable, and problems such as sediment deposition, scale buildup, rust corrosion, oil pollution, and the attachment of aquatic plants and animals can gradually form a layer of dirt on the screw surface. This leads to increased surface roughness, reduced thread clearance, and consequently, accelerated wear, jamming, or a significant decrease in transmission efficiency. In severe cases, it can even affect the normal opening and closing of the gate and the safe operation of the hydraulic system. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where screws are prone to accelerated wear in complex underwater environments over long periods of time, and to propose a hydraulic diversion flow regulation device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A hydraulic diversion flow regulation device is designed, comprising a gate frame, a power box fixedly installed at the top of the gate frame, a screw connected to the lower end of the power box, a movable seat threaded on the outer side of the screw, a gate plate fixedly installed at one end of the movable seat, the gate plate being slidably disposed within the gate frame, a bottom sill fixedly installed at the bottom of the gate frame, an upper support plate and a lower support plate fixedly installed on the back of the top and bottom of the gate frame respectively, the lower end of the screw penetrating through the upper support plate and rotatably connected to the lower support plate, a first protective sleeve fixedly installed on the lower surface of the upper support plate and the upper surface of the movable seat, and a second protective sleeve fixedly installed on the lower surface of the movable seat and the upper surface of the lower support plate.

[0008] Preferably, a fixing ring is fixedly installed on the lower surface of the upper support plate, the upper surface of the lower support plate, and the upper and lower side surfaces of the movable seat. The first protective sleeve is separated from the lower surface of the upper support plate and the upper surface of the movable seat, and the second protective sleeve is separated from the lower surface of the movable seat and the upper surface of the lower support plate. The ends of the first protective sleeve and the second protective sleeve are respectively fixedly installed inside the fixing ring by the first bolt.

[0009] Preferably, the central axis of the first protective sleeve and the second protective sleeve coincides with the central axis of the screw.

[0010] Preferably, the interior of the first and second protective sleeves is made of polyurethane.

[0011] Preferably, a protective plate is fixedly installed on the inner side of the top of the door frame, the protective plate is disposed through the movable seat, and the bottom of the protective plate is in contact with the bottom sill.

[0012] Preferably, the protective plate has an arc-shaped cross-section and the opening faces the screw.

[0013] Preferably, the length direction of the protective plate is parallel to the length direction of the screw.

[0014] Preferably, the bottom sill is separate from the door frame and is fixedly connected by a second bolt.

[0015] The water diversion flow regulation device proposed in this utility model has the following advantages: When the water diversion flow regulation device is working, the first protective sleeve and the second protective sleeve wrap around the screw. When the screw rotates and drives the movable seat to move up and down, the first protective sleeve and the second protective sleeve will also expand or contract synchronously, which isolates the influence of impurities in the water on the screw and can prevent the screw from wearing or getting stuck.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example 1: Refer to Figure 1-3 A water diversion flow regulation device includes a gate frame 1, a power box 2 fixedly installed on the top of the gate frame 1, a screw 3 connected to the lower end of the power box 2, and the screw 3 set on the backwater surface of the gate plate 5. The power box 2 is a driving device in the prior art, including an electric motor and a detection device. The electric motor can drive the screw 3 to rotate through a reduction device. A movable seat 4 is threaded on the outside of the screw 3. The rotation of the screw 3 can drive the movable seat 4 to move up and down. A gate plate 5 is fixedly installed at one end of the movable seat 4. The up and down movement of the movable seat 4 can drive the gate plate 5 to move up and down. The gate plate 5 is slidably set in the gate frame 1. The gate frame 1 can keep the gate plate 5 stable when it moves up and down.

[0026] A bottom sill 12 is fixedly installed at the bottom of the door frame 1. When the gate 5 is fully closed, the bottom of the gate 5 abuts against the bottom sill 12. An upper support plate 6 and a lower support plate 7 are fixedly installed on the back of the top and bottom of the door frame 1, respectively. The lower end of the screw 3 passes through the upper support plate 6 and is rotatably connected to the lower support plate 7. A first protective sleeve 9 is fixedly installed on the lower surface of the upper support plate 6 and the upper surface of the movable seat 4. A second protective sleeve 10 is fixedly installed on the lower surface of the movable seat 4 and the upper surface of the lower support plate 7. The central axes of the first protective sleeve 9 and the second protective sleeve 10 coincide with the central axis of the screw 3. The first protective sleeve 9 and the second protective sleeve 10 are both sleeved on the outside of the screw 3 and do not affect the rotation of the screw 3.

[0027] The first protective sleeve 9 and the second protective sleeve 10 are made of polyurethane and are expandable / contractable. When the power box 2 drives the screw 3 to rotate, the screw 3 drives the movable seat 4 to move downwards, at which point the first protective sleeve 9 is stretched and the second protective sleeve 10 is compressed. When the movable seat 4 moves upwards, the first protective sleeve 9 is compressed and the second protective sleeve 10 is stretched and expanded. The protective sleeves on both the upper and lower sides can always cover the screw 3 without hindering its rotation. The protective sleeves expand or contract synchronously with the screw 3 as it rises and falls, isolating mud, sand, weeds, and other debris in the water flow and preventing wear or jamming of the screw 3.

[0028] Working principle: When the water diversion flow regulating device is working, the power box 2 drives the screw 2 to rotate. The rotation of the screw 2 drives the movable seat 4 to move upward. The movable seat 4 drives the gate plate 6 to move upward, and the gate is in the open state. When the screw 2 drives the movable seat 4 to move downward, the gate plate 6 moves downward and abuts against the bottom sill 12, and the gate is in the closed state. When the movable seat 4 moves up and down, the first protective sleeve 9 and the second protective sleeve 10 expand or contract synchronously to isolate the screw 3 from the influence of debris in the water and prevent the screw 3 from wearing or jamming.

[0029] Example 2: In Example 1, after prolonged stretching and contraction, the first protective sleeve 9 and the second protective sleeve 10 will experience wear and tear, potentially leading to damage and affecting the protective effect. Therefore, this example is proposed. (Refer to...) Figure 4-5 In another preferred embodiment of this utility model, the difference from Embodiment 1 is that fixing rings 8 are fixedly installed on the lower surface of the upper support plate 6, the upper surface of the lower support plate 7, and the upper and lower side surfaces of the movable seat 4. The first protective sleeve 9 is separated from the lower surface of the upper support plate 6 and the upper surface of the movable seat 4, and the second protective sleeve 10 is separated from the lower surface of the movable seat 4 and the upper surface of the lower support plate 7. Unlike Embodiment 1, the ends of the two protective sleeves are not fixed and can be disassembled. The ends of the first protective sleeve 9 and the second protective sleeve 10 are respectively fixedly installed inside the fixing rings 8 by the first bolts 14. The ends of the protective sleeves need to be made of high-hardness plastic so that they can be squeezed and tightened by the first bolts 14. A crack is provided through one side of the protective sleeve, which makes it easy to put the protective sleeve on the screw 7 and also easy to remove and replace the protective sleeve. At the same time, the crack can be sealed with glue. When the protective cover is damaged, cut off the old protective cover with scissors and remove it. Then put the new protective cover on the outside of the screw 3, seal the crack with glue, and finally fix the end of the protective cover with the first bolt 14.

[0030] Example 3: In Example 1, the protective sleeve is retractable. If the water flow is too rapid, the water will impact the protective sleeve, causing the water-facing surface of the sleeve to come into contact with the screw 3. In this case, the rotation of the screw 3 will cause wear to the protective sleeve. If there are sharp objects in the water that come into contact with the protective sleeve, they may puncture it, all of which will affect the service life of the protective sleeve. Therefore, this example is proposed. (Refer to...) Figure 6-7 As another preferred embodiment of this utility model, the difference from embodiment 1 or embodiment 2 is that a protective plate 13 is fixedly installed on the inner side of the top of the door frame 1. The protective plate 13 is set through the movable seat 4. The bottom of the protective plate 13 is in contact with the bottom sill 12. The cross section of the protective plate 13 is arc-shaped and the opening faces the screw 3. The length direction of the protective plate 13 is parallel to the length direction of the screw 3. The protective plate 13 can protect the protective sleeve.

[0031] The protective plate 13 is installed on the water-facing side of the protective sleeve 9. When water flows towards the protective sleeve, the protective plate 13 can prevent the water flow from directly impacting the protective sleeve and avoid deformation caused by the water flow. The protective plate 13 can also block sharp debris in the water flow, preventing the debris from damaging the protective sleeve.

[0032] Example 4: In Example 1, the sill 12 is relatively low and, being submerged in water for extended periods, is susceptible to corrosion. Damage to the sill 12 necessitates extensive repair of the entire door frame 1, which is quite troublesome. Therefore, this example is proposed. (Refer to...) Figure 1-3 As another preferred embodiment of this utility model, the difference from Embodiment 1, Embodiment 2 or Embodiment 3 is that the bottom sill 12 is separated from the door frame 1 and fixedly connected by the second bolt 11. The bottom sill 12 can be removed from the door frame 1, and the corroded bottom sill 12 can be replaced with a new bottom sill 12, avoiding overall drainage maintenance.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
