Description
Technical Field
[0001] The utility model relates to a flood control gate for water conservancy projects, belonging to the technical field of water conservancy and flood control. Background Art
[0002] Flood gates are an important type of water conservancy engineering facility whose main function is to control water flow during floods to prevent flooding from causing damage to surrounding areas.
[0003] There are two types of flood gates: vertical flood gates and flap gates. The vertical flood gate controls the gate up and down through a drive device to open and close the gate. However, since the vertical flood gate needs to be controlled to lift and lower, the compressive strength between the lifting shaft and the gate connection point is low. When the water volume is large, the gate may bend and be damaged at the connection point. Utility Model Content
[0004] The technical problem to be solved by the utility model is to provide a flood control gate for water conservancy projects, which solves the problem in the prior art that the connection point between the gate and the lifting shaft of the vertical gate cannot withstand greater pressure.
[0005] The technical problem to be solved by the present invention is achieved by adopting the following technical solutions: A flood control gate for water conservancy projects, comprising: a gate body, slidably arranged in the center of a waterway; a lifting shaft, one end of which is connected to the gate body and the other end is connected to a driver, the lifting shaft being used to control the lifting of the gate; a hinged disc, coaxially arranged at the bottom position of the gate body with the lifting shaft, a first connecting rod hinged on the hinged disc, the other end of the first connecting rod hinged to a pushing block, the pushing block being slidably arranged at the bottom of the waterway and sliding with the lifting and lowering of the gate body, a pushed block being further provided at the bottom of the waterway, the pushed block sliding coaxially with the pushing block; a second connecting rod, one end of which is hinged to the upper position of the gate body and the other end is hinged to the pushed block.
[0006] By adopting the above technical solution, the compressive strength of the gate body can be greatly improved, so that the pressure-bearing capacity of the connection point between the gate plate and the lifting shaft is improved during the descent and ascent of the gate body, thereby reducing the risk of damage to the gate plate due to excessive water pressure.
[0007] The utility model is further configured as follows: a deep hole is provided at the bottom of the gate body, a reinforcement rod is slidably provided in the deep hole, and the reinforcement rod is coaxially arranged with the lifting shaft.
[0008] By adopting the above technical solution, the reinforcement rod can improve the overall strength of the gate body. When water impacts the gate plate, the reinforcement rod can serve as a support point for the gate plate to prevent the lifting shaft connected to the gate plate from bending when the gate plate is impacted.
[0009] The utility model is further configured as follows: the gate body is formed by two gate plates connected at an angle less than one hundred and eighty degrees, the lifting shaft is fixed at the middle upper position of the connection point of the two gate plates, and the gate plates are connected at an angle less than one hundred and eighty degrees toward the other side of the water body.
[0010] By adopting the above technical solution,
[0011] The utility model is further configured as follows: a clamping plate is extended outward from the side of the gate plate, and a clamping groove for slidingly clamping the clamping plate is provided on the wall surfaces on both sides of the waterway.
[0012] By adopting the above technical solution, the clamping plates are arranged on both sides of the gate plate, and are slidably clamped in the clamping grooves on the walls on both sides of the waterway, thereby improving the compressive strength on the edge lines of the gate plate.
[0013] The utility model is further configured as follows: a groove is provided on the waterway surface below the hinged disc, and the groove is used to clamp the hinged disc. When the gate body is in a closed state, the bottom of the gate plate is in contact with the bottom surface of the waterway, and the hinged disc is clamped in the groove.
[0014] By adopting the above technical solution, the groove below the hinged disc can accommodate the hinged disc after the gate falls and closes, so that the bottom of the gate and the bottom surface of the waterway fit together without leaving any gaps, thereby improving the flood prevention capacity of the entire gate and making the entire device more tightly connected.
[0015] The utility model is further configured as follows: a slide groove is provided on the bottom surface of the water channel for slidingly engaging the pushing member and the pushed member, and the slide groove is communicated with the groove.
[0016] By adopting the above technical solution, the slide groove can guide the pushing block and the pushed block to prevent the pushing block and the pushed block from offsetting during the sliding process. At the same time, after the gate plate falls, the slide groove can be used to accommodate the first connecting rod to prevent interference between the connecting rod and the hinged disc.
[0017] The utility model is further configured as follows: the water inlets on both sides of the water channel are provided with diversion angles.
[0018] By adopting the above technical solution, the direction of water flow can be effectively controlled, thereby guiding the water flow in the waterway.
[0019] The beneficial effect of the utility model is that through the arrangement of the first connecting rod and the second connecting rod, the entire flood control gate can cooperate with each other through the first connecting rod and the second connecting rod when it is raised and lowered, thereby playing an impact-resistant role for the gate body and preventing the gate plate from being damaged due to the high pressure at the bottom of the gate body.
[0020] By setting the gate body into a bent shape, with the bending line in the middle corresponding to the centerline of the entire waterway, and coordinating with the diversion angles set on the water inlets on both sides of the waterway, the water body can be diverted into two parts, reducing the compressive strength of the transmission position in the middle of the gate body, and ensuring that the entire flood gate can be raised and lowered normally.
[0021] The clamping plates on both sides of the gate can effectively improve the compressive strength of both sides of the gate, so that the gate will not bend when under pressure. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention is further described below with reference to specific illustrations.
[0026] like Figure 1 and Figure 2 As shown, a flood gate for water conservancy projects includes: a gate body 1, which is slidably arranged in the center of a waterway 16; a lifting shaft 2, one end of which is connected to the gate body 1, and the other end is connected to a driver 3, and the lifting shaft 2 is used to control the lifting of the gate body 1; when the flood gate needs to be closed or opened, the lifting shaft 2 is controlled by the driver 3 to be lifted and lowered, thereby driving the gate body 1 to be lifted and lowered, and the driver 3 is specifically a hydraulic cylinder.
[0027] Furthermore, a hinged disc 4 is provided at the bottom of the gate body 1, and the hinged disc 4 is coaxially arranged with the lifting shaft 2. A first connecting rod 5 is hinged on the hinged disc 4, and the other end of the first connecting rod 5 is hinged to a pushing block 6. The pushing block 6 is slidably provided at the bottom of the waterway 16 and slides as the gate body 1 is raised and lowered. A pushed block 7 is also provided at the bottom of the waterway 16, and the pushed block 7 slides coaxially with the pushing block 6. A second connecting rod 8 is hinged at one end to the upper position of the gate body 1 and at the other end to the pushed block 7. The movement of the pushing block 6 is controlled by the first connecting rod 5, so that the pushing block 6 can slide as the gate body 1 is raised and lowered, thereby pushing the pushed block 7 to slide, so that the second connecting rod 8 used to reinforce the upper part of the gate body 1 can also deflect synchronously with the movement of the gate body 1.
[0028] The second connecting rod 8 can reinforce the connection point between the gate body 1 and the lifting shaft 2 to a certain extent, so that the impact force of the water flow on the connection point can be transmitted to the second connecting rod 8, thereby improving the supporting strength of the entire flood gate when opening and closing.
[0029] Furthermore, a deep hole is provided at the bottom of the gate body 1 , and a reinforcement rod 9 is slidably provided in the deep hole. The reinforcement rod 9 is coaxially provided with the lifting shaft 2 .
[0030] During the lifting and lowering process of the gate body 1, when the gate body 1 descends, the first connecting rod 5, which is hingedly connected to the hinged disc 4 at the bottom of the gate body 1, can control the pushing block 6 to slide at the bottom of the waterway 16, thereby pushing the pushed block 7 to slide, allowing the second connecting rod 8 to smoothly deflect with the sliding of the pushed block 7. The reinforcement rod 9 reinforces the gate body 1, and the pressure exerted on the gate body 1 can be transmitted to the reinforcement rod 9, thereby preventing the gate body 1 from being damaged when subjected to large water pressure.
[0031] When the gate is rising, since the bottom of the gate plate 10 is separated from the bottom surface of the waterway 16, a large amount of water flows out through the gap at the bottom of the gate plate 10 at this time, causing a large impact on the gate plate 10. The bottom of the gate plate 10 is hinged to the first connecting rod 5 through the hinged disc 4, and the reinforcement rod 9 is inserted into the middle of the gate body 1, so that most of the pressure on the gate body 1 can be transmitted to the reinforcement rod 9. At the same time, the second connecting rod 8 is hinged at the connection point between the gate body 1 and the lifting shaft 2, and the upper part of the gate body 1 is connected through the second connecting rod 8, so that the upper part of the gate body 1 can be reinforced by the second connecting rod 8.
[0032] Furthermore, the gate body 1 is formed by two gate plates 10 connected at an angle less than one hundred and eighty degrees, and the lifting shaft 2 is fixed at the middle upper position of the connection point of the two gate plates 10. After the gate plates 10 are connected, the angle less than one hundred and eighty degrees is directed toward the other side of the water body.
[0033] Since most of the transmission components are arranged in the middle part of the gate body 1, the compressive strength of the middle part of the gate body 1 is the lowest. The bent gate body 1 can divide the water flow into two parts, left and right, so that most of the impact force of the water body is transmitted to both sides of the gate body 1, so that the impact force of the water flow in the middle position of the waterway 16 is minimized.
[0034] Furthermore, the water inlets on both sides of the waterway 16 are provided with diversion angles 15. They can play a diversion role on the water body, and when the gate is opened, the water can flow out quickly through the gate.
[0035] Furthermore, a clamping plate 11 extends outward from the side of the gate plate 10 , and a clamping groove 12 for slidingly clamping the clamping plate 11 is provided on the wall surfaces on both sides of the water channel 16 .
[0036] Since the water flow pressure is transferred to the two sides of the gate body 1, by arranging the clamping plates 11 on both sides of the gate plate 10 and clamping the clamping plates 11 into the clamping grooves 12 on the walls on both sides of the waterway 16, the compressive strength of the side of the gate plate 10 can be increased, and the gate plate 10 can be prevented from bending due to excessive pressure on the side.
[0037] A groove 13 is provided on the surface of the waterway 16 below the hinged disc 4. The groove 13 is used to engage the hinged disc 4. When the gate body 1 is in the closed state, the bottom of the gate plate 10 is in contact with the bottom surface of the waterway 16, and the hinged disc 4 is engaged with the groove 13. The groove 13 below the hinged disc 4 can accommodate the hinged disc 4 after the gate plate 10 falls and closes, so that the bottom of the gate plate 10 and the bottom surface of the waterway 16 are in contact with each other without leaving any gaps, thereby improving the flood prevention capability of the entire gate plate 10 and also making the entire device more tightly connected.
[0038] Furthermore, a chute 14 is provided on the bottom surface of the water channel 16 for slidingly engaging the pushing member and the pushed member, and the chute 14 is connected to the groove 13. The chute 14 can guide the pushing block 6 and the pushed block 7 to prevent the pushing block 6 and the pushed block 7 from deviating during the sliding process.
[0039] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art will appreciate that the present invention is not limited to the above embodiments and that various modifications and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such modifications and improvements fall within the scope of protection claimed by the present invention. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
