Description

Technical Field

[0001] The utility model belongs to the technical field of water conservancy projects, and in particular relates to a water conservancy project gate. Background Art

[0002] Water conservancy projects are projects built to control and allocate natural surface water and groundwater in order to achieve the purpose of eliminating harm and promoting benefits. Water is a precious resource that is indispensable to human production and life, but its natural state does not fully meet human needs. Only by building water conservancy projects can we control water flows, prevent floods and waterlogging disasters, and regulate and distribute water to meet people's needs for water resources in life and production.

[0003] A hydraulic gate is a control facility used for storing and releasing water in rivers or dams. It is an important component of hydraulic engineering buildings and can be used to intercept water flow, control water level, regulate flow, discharge silt and floating objects, etc. When the gate is in use, if there are large stones on the water inlet side of the gate, it is easy for the gate to be hit by the water flow. Long-term impact will greatly reduce the service life of the gate. When the gate is opened, the water flow pressure at the bottom increases instantly, which will cause a certain impact on the gate plate. Such impact force for a long time will cause the gate to deform to a certain extent, thus affecting the overall use effect.

[0004] Therefore, a water conservancy project gate is needed to solve the problems in the prior art that larger stones in the water flow easily hit the gate and cause damage to the gate, and the larger water flow impact when the gate is opened easily causes the gate to deform and affect normal use. Utility Model Content

[0005] The purpose of the utility model is to provide a water conservancy project gate to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a water conservancy project gate, including a gate frame, a top plate fixedly connected to the top surface of the gate frame, installation grooves are provided on the inner walls on both sides of the gate frame, and the same gate plate is slidably connected between the inner walls of the two installation grooves, a vertically arranged driving motor is fixedly connected to the center of the top surface of the top plate, a screw is coaxially fixedly connected to the output end of the driving motor, mounting rods are fixedly connected to both sides of the outer wall of one end of the gate frame, a protective mechanism is provided on the end of the mounting rod away from the gate frame, and a flow reducing mechanism is provided between the outer walls on the opposite side of the mounting rod.

[0007] It should be noted in the scheme that the protection mechanism includes four slots respectively opened on the outer walls of one end of the two mounting rods, and the two slots located on the same mounting rod are symmetrically distributed. A guide rod is fixedly connected between the top and bottom surfaces inside each slot, and a slider is slidably connected to the outer surface of the guide rod. A first spring is sleeved on the outer surface of the guide rod, and the top end of the first spring is fixedly connected to the top surface of the slot, and the bottom end of the first spring is fixedly connected to the top surface of the slider. A connecting rod is hinged on the outer wall of one end of the slider, and the four connecting rods are hinged to the same baffle at one end away from the slider.

[0008] It is further worth explaining that the flow reducing mechanism comprises two mounting shells respectively fixedly connected to the bottom of the outer wall on the opposite side of the mounting rod, a rotating shaft is rotatably connected between the inner walls of the two mounting shells close to the mounting rod, a plurality of circumferentially distributed blades are fixedly connected to the outer surface of the rotating shaft located outside the mounting shell, a buffer ring is fastened to the outer surface of the rotating shaft located inside the mounting shell, a second spring is fixedly connected to the center of the inner walls at both ends of the two mounting shells, and a damping block is fixedly connected to the end of the second spring away from the mounting shell.

[0009] It should be further explained that the bottom end of the screw rod passes through the top plate and is threadedly connected to the gate plate, and a plurality of evenly distributed through holes are formed on the outer wall of one end of the baffle plate.

[0010] As a preferred implementation, the area of ​​the baffle is larger than the area of ​​the gate plate, and the length of the buffer ring is equal to that of the damping block and is smaller than the inner diameter of the mounting shell.

[0011] As a preferred implementation, the damping block is an arc-shaped structure and its inner diameter is the same as the outer diameter of the buffer ring, and the inner wall of the damping block is in conflict with the outer wall of the buffer ring.

[0012] Compared with the prior art, the utility model provides a water conservancy engineering gate, which at least includes the following

[0013] Beneficial effects:

[0014] (1) Through the action of the protective mechanism, the baffle intercepts larger stones in the water flow. After the baffle is impacted by the stone, the impact force is transmitted to the slider through the connecting rod, so that the slider moves on the guide rod. At the same time, the impact force is buffered under the action of the first spring to prevent the baffle from being damaged, thereby increasing the service life of the gate and the baffle, and effectively avoiding the problem that larger stones in the water flow easily hit the gate and cause damage to the gate.

[0015] (2) Through the adjustment of the flow reduction mechanism, when the gate is opened, the water flow velocity at the bottom of the gate accelerates to drive the blade to rotate, thereby driving the buffer rings on both sides of the shaft to rotate. The outer wall of the buffer ring abuts against the inner wall of the damping block to generate friction, thereby generating a reaction force on the rotating blade, slowing down the flow velocity of the water flow, and effectively avoiding the problem that the large water flow impact when the gate is opened easily causes the gate to deform and affect normal use.

DETAILED DESCRIPTION

[0020] The present invention will be further described below in conjunction with the embodiments.

[0021] See also Figure 1-3 The utility model provides a water conservancy project gate, including a gate frame 1, a top plate 2 is fixedly connected to the top surface of the gate frame 1, mounting grooves 3 are opened on the inner walls on both sides of the gate frame 1, and the same gate plate 4 is slidably connected between the inner walls of the two mounting grooves 3, a vertically arranged driving motor 5 is fixedly connected to the center of the top surface of the top plate 2, a screw 6 is coaxially fixedly connected to the output end of the driving motor 5, mounting rods 7 are fixedly connected to both sides of the outer wall of one end of the gate frame 1, a protection mechanism 8 is arranged on the end of the mounting rod 7 away from the gate frame 1, and a flow reduction mechanism 9 is arranged between the outer walls on the opposite side of the mounting rod 7.

[0022] Further Figure 1 and Figure 2As shown, it is worth explaining in detail that the protection mechanism 8 includes four slot holes 81 respectively opened on the outer wall of one end of the two mounting rods 7, the two slot holes 81 located on the same mounting rod 7 are symmetrically distributed, a guide rod 82 is fixedly connected between the top and bottom surfaces inside each slot hole 81, a slider 83 is slidably connected to the outer surface of the guide rod 82, a first spring 84 is sleeved on the outer surface of the guide rod 82, the top end of the first spring 84 is fixedly connected to the top surface of the slot hole 81, the bottom end of the first spring 84 is fixedly connected to the top surface of the slider 83, a connecting rod 85 is hinged on the outer wall of one end of the slider 83, and the four connecting rods 85 are hinged on the same baffle 86 at one end away from the slider 83.

[0023] Further Figure 1 and Figure 3 As shown, it is worth explaining in detail that the flow reducing mechanism 9 includes two mounting shells 91 respectively fixedly connected to the bottom of the outer wall on the opposite side of the mounting rod 7, a rotating shaft 92 is rotatably connected between the inner walls of the two mounting shells 91 close to the mounting rod 7, the outer surface of the rotating shaft 92 located outside the mounting shell 91 is fixedly connected with a plurality of circumferentially distributed blades 93, the outer surface of the rotating shaft 92 located inside the mounting shell 91 is fastened with a buffer ring 94, the center of the inner walls at both ends of the two mounting shells 91 are fixedly connected with a second spring 95, and the end of the second spring 95 away from the mounting shell 91 is fixedly connected with a damping block 96.

[0024] Further Figure 1 As shown, it is worth explaining in detail that the bottom end of the screw rod 6 passes through the top plate 2 and is threadedly connected to the gate plate 4, and a plurality of evenly distributed through holes 10 are opened on the outer wall of one end of the baffle plate 86.

[0025] This solution has the following working process: when the gate is in use, the multiple through holes 10 on the baffle 86 can block the passage of larger stones in the water, so that the baffle 86 can achieve the purpose of anti-collision for the gate plate 4, preventing larger stones from continuously impacting and damaging the gate plate 4. When the baffle 86 intercepts larger stones, the baffle 86 moves under force, and transmits the impact force to the slider 83 through the connecting rod 85, so that the slider 83 moves on the guide rod 82, and the impact force received is buffered under the action of the first spring 84, thereby extending the service life of the baffle 86.

[0026] When the gate is opened, the drive motor 5 is turned on first, and the drive motor 5 drives the screw 6 to rotate, and the gate plate 4 is driven to move upward in the mounting groove 3 under the action of the thread. At this time, the water flow at the bottom of the gate plate 4 is accelerated, and the water flow drives the vane 93 to rotate. While the vane 93 rotates, the buffer rings 94 on both sides of the outer surface of the rotating shaft 92 rotate synchronously, and the outer wall of the buffer ring 94 abuts against the inner wall of the damping block 96 to generate friction, which gives the rotating vane 93 a reaction force, effectively slowing down the flow rate of the bottom water flow when the gate plate 4 is opened, and further reducing the impact of the water flow on the gate plate 4 when it is opened.

[0027] According to the above working process, it can be known that: through the action of the protection mechanism 8, the baffle 86 intercepts larger stones in the water flow. After the baffle 86 is impacted by the stone, the impact force is transmitted to the slider 83 through the connecting rod 85, so that the slider 83 moves on the guide rod 82. At the same time, under the action of the first spring 84, the impact force is buffered to prevent the baffle 86 from being damaged, thereby improving the service life of the gate 4 and the baffle 86, and effectively avoiding the problem that larger stones in the water flow easily hit the gate and cause damage to the gate.

[0028] Through the adjustment of the flow reduction mechanism 9, when the gate is opened, the water flow velocity at the bottom of the gate plate 4 accelerates to push the vane 93 to rotate, thereby driving the buffer rings 94 on both sides of the rotating shaft 92 to rotate. The outer wall of the buffer ring 94 abuts against the inner wall of the damping block 96 to generate friction, thereby generating a reaction force on the rotating vane 93, slowing down the flow velocity of the water flow, and effectively avoiding the problem that the large water flow impact when the gate is opened easily causes the gate to deform and affect normal use.

[0029] Further Figure 1 and Figure 3 As shown, it is worth explaining in detail that the area of ​​the baffle 86 is larger than the area of ​​the gate plate 4, which is convenient for better intercepting larger stones in the water and better protecting the gate plate 4. The buffer ring 94 is equal to the damping block 96 in length and is smaller than the inner diameter of the mounting shell 91, ensuring that the buffer ring 94 rotates normally in the mounting shell 91.

[0030] Further Figure 3 As shown, it is worth explaining in detail that the damping block 96 is an arc-shaped structure and its inner diameter is the same as the outer diameter of the buffer ring 94 . The inner wall of the damping block 96 abuts against the outer wall of the buffer ring 94 , so that the damping block 96 can better act on the buffer ring 94 .

[0031] In summary: when the gate is in use, the multiple through holes 10 on the baffle 86 can block the passage of larger stones in the water, so that the baffle 86 can achieve the purpose of anti-collision for the gate 4, and prevent the larger stones from continuously impacting and damaging the gate 4. When the baffle 86 intercepts the larger stones, the baffle 86 is forced to move, and the impact force received is transmitted to the slider 83 through the connecting rod 85, so that the slider 83 moves on the guide rod 82, and the impact force received is buffered under the action of the first spring 84, thereby extending the service life of the baffle 86, and effectively avoiding the problem that larger stones in the water flow easily hit the gate and cause damage to the gate.

[0032] When the gate is opened, the driving motor 5 is turned on first, and the driving motor 5 drives the screw 6 to rotate, and the gate plate 4 is driven to move upward in the mounting groove 3 under the action of the thread. At this time, the water flow at the bottom of the gate plate 4 is accelerated, and the water flow drives the vane 93 to rotate. While the vane 93 rotates, the buffer rings 94 on both sides of the outer surface of the rotating shaft 92 rotate synchronously, and the outer wall of the buffer ring 94 abuts against the inner wall of the damping block 96 to generate friction, which gives a reaction force to the rotating vane 93, effectively slowing down the flow rate of the bottom water flow when the gate plate 4 is opened, and further reducing the impact of the water flow on the gate plate 4 when it is opened, effectively avoiding the problem that the large water flow impact when the gate is opened easily causes the gate to deform and affect normal use.

[0033] The drive motor 5 can be purchased on the market. The drive motor 5 is equipped with a power supply, which is a mature technology in this field and has been fully disclosed, so it will not be repeated in the specification.
