Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water conservancy engineering, in particular to a water conservancy engineering flow control gate with dredging function. BACKGROUND

[0002] In the field of water conservancy engineering, the flow control gate is a key device for regulating water flow, flood control and drainage, and water resource allocation. Its performance directly affects the operation efficiency and safety of the water conservancy system. At present, the mainstream water conservancy gate on the market adopts an electric or hydraulic driving mode. The electrically driven gate relies on the power system for opening and closing operation. In remote areas or in the event of power failure, the gate may not operate normally, which seriously affects the emergency response capability of the water conservancy project. The hydraulic drive gate has a large driving force, but the hydraulic system has the risk of oil leakage, which not only causes environmental pollution, but also requires frequent maintenance, resulting in a substantial increase in operating costs.

[0003] To realize the monitoring and control of water level and water flow state, the existing gate system generally uses sensor technology. For example, the water level sensor monitors the change of water level, and then transmits the signal to the control system to control the opening and closing of the gate. However, the sensor is easily affected by factors such as water flow impact, silt erosion, and water corrosion in complex water conservancy environment, resulting in problems such as decreased sensitivity, data deviation, and even failure, which reduces the stability and reliability of the system. In addition, the sensor and its supporting electronic control equipment are costly, further increasing the construction and maintenance cost of the water conservancy project. Therefore, the existing water conservancy gate relies on electricity, hydraulic pressure and sensors in terms of working principle, which has obvious deficiencies in reliability, maintainability and economy. There is an urgent need for a water conservancy gate that breaks through the traditional technical path and adopts a new working principle to meet the efficient, stable and low-cost operation requirements of water conservancy projects.

[0028] In this embodiment, referring to Figures 1-6 The inner wall of the channel 110b is provided with a mounting groove 110b-1 on both sides, which is used to facilitate the installation of the water storage cylinder 210a and to hide the water storage cylinder 210a, so as to avoid occupying the area in the channel 110b and affecting the drainage; Referring to Figures 1-6 The water level sensing mechanism 200 includes a water level sensing assembly 210 located in the mounting groove 110b-1 and used to sense the water level in the channel 110b in real time, and a first transmission assembly 220 having one end connected with the water level sensing mechanism and the other end connected with the gate body 120, the water level sensing assembly 210 is used to sense the water level in the channel 110b in real time, and the first transmission assembly 220 is used to automatically drive the two gate bodies 120 to move away from each other when the water level sensing assembly 210 senses that the water level in the channel 110b reaches a certain depth.

[0030] In the embodiment, referring to Figures 1-6 , the first transmission assembly 220 comprises a force amplification driving assembly 220a at one end of which the transmission connection with the buoy 210b and a linkage assembly 220b at one end of which the transmission connection with the force amplification driving assembly 220a and at the other end of which the transmission connection with the gate body 120, the force amplification driving assembly 220a is used to drive the linkage assembly 220b to work when the buoy 210b rises, and the linkage assembly 220b is used to drive the two gate bodies 120 to approach or move away from each other when working.

[0031] In the embodiment, referring to Figures 1-6 , the top of the buoy 210b is provided with a limiting sliding groove 210b-1 for facilitating the sliding installation of the hinged seat 220a-2; Referring to Figures 1-6 , the two sides of the chimney 110b are provided with first through grooves 110b-2 in communication with the installation grooves 110b-1 for facilitating the connection of the two ends of the connecting plate 220a-3 with the rotating rod 220a-11 and the hinged seat 220a-2, respectively; Referring to Figures 1-6 , the force amplification driving assembly 220a comprises a mounting bracket 220a-1 located at the side wall of the chimney 110b and having a rotating rod 220a-11 at the top, a hinged seat 220a-2 located in the limiting sliding groove 210b-1, and a connecting plate 220a-3 sleeved at one end on the rotating rod 220a-11 and hinged at the other end with the hinged seat 220a-2, the mounting bracket 220a-1 is used to facilitate the connection of the connecting plate 220a-3 and the linkage assembly 220b, the rotating rod 220a-11 is used to facilitate the connection of one end of the connecting plate 220a-3, the connecting seat is used to drive the linkage assembly 220b to work when the connecting plate 220a-3 is flipped with the rotating rod 220a-11 as the axis, the connecting plate 220a-3 passes through the first through groove 110b-2, and the axis position of the connecting plate 220a-3 connected with the rotating rod 220a-11 is located at the end of the connecting plate 220a-3 away from the hinged seat 220a-2, so that the connecting plate 220a-3 becomes a lever with the rotating rod 220a-11 as the axis, and thus when the buoy 210b rises to drive the hinged seat 220a-2 to rise and the connecting plate 220a-3 is flipped, the force output by the connecting plate 220a-3 is increased, thereby avoiding the indirect driving of the movement of the gate body 120 due to the insufficient buoyancy of the buoy 210b.

[0032] In the embodiment, referring to Figures 1-6 , the end of the connecting plate 220a-3 close to the rotating rod 220a-11 is provided with an arc sawtooth block, which is used to drive the rotating disc 220b-1 to rotate when the connecting plate 220a-3 is flipped through the cooperation of the arc sawtooth block and the arc sawtooth plate 220b-11; Referring to Figures 1-6The sidewall of the dam 110a has a second through slot 110a-2 communicating with the gate slot 110a-1, for facilitating the first sawtooth to extend out to engage with the first gear 220b-3; Referring to Figures 1-6 The sidewall of the dam body 120 extending out of the second through slot 110a-2 has the first sawtooth plate 120b, for driving the first sawtooth plate 120b and the dam body 120 to move in the gate slot 110a-1 when the first gear 220b-3 rotates; Referring to Figures 1-6 The linkage assembly 220b includes a rotating disc 220b-1 on the sidewall of the mounting frame 220a-1, a differential gear 220b-2 on the sidewall of the rotating disc 220b-1, and a first gear 220b-3 on the other end of the differential gear 220b-2 and engaging with the first sawtooth plate 120b, the rotating disc 220b-1 is used to rotate to drive the differential gear 220b-2 to rotate, the differential gear 220b-2 is used to rotate to drive the first gear 220b-3 to accelerate rotation, the first gear 220b-3 is used to rotate to drive the dam body 120 to move under the cooperation of the first sawtooth plate 120b, the sidewall of the rotating disc 220b-1 has an arc sawtooth plate 220b-11 engaging with the arc sawtooth block, since the arc sawtooth block, the arc sawtooth plate 220b-11 and the axis of the rotating disc 220b-1 are on the same axis, when the connecting plate 220a-3 is flipped with the rotating rod 220a-11 as the axis, the rotating disc 220b-1 is driven to rotate under the flipping of the arc sawtooth block.

[0033] In the embodiment, the specific working process is as follows: when the water level in the duct 110b increases, the water in the duct 110b enters the water storage cylinder 210a through the water inlet slot 210a-1, when the water level in the water storage cylinder 210a exceeds the limit ring, it is necessary to drain water, the buoyancy cylinder 210b is synchronously raised with the water level under the action of its own buoyancy, when the buoyancy cylinder 210b rises, the connecting plate 220a-3 is flipped with the rotating rod 220a-11 as the axis, thereby indirectly driving the rotating disc 220b-1 to rotate and at the same time enhancing the driving force of the rotating disc 220b-1, when the rotating disc 220b-1 rotates, the differential gear 220b-2 is driven to rotate, when the differential gear 220b-2 rotates, the first gear 220b-3 is driven to accelerate rotation, when the first gear 220b-3 rotates, the two dam bodies 120 are driven to move away from each other under the meshing action of the first sawtooth plate 120b, thereby opening the gate slot 110a-1, and then timely draining water, in this process, the water level is sensed in real time through the physical properties of the buoyancy cylinder 210b; In order to, in the case that the buoyancy of the buoyancy cylinder 210b is too small, the gate body 120 and the dredging mechanism 300 cannot be driven to work, therefore, a driving member is arranged in the water storage cylinder 210a, water level meters are arranged inside and outside the water storage cylinder 210a, when the water level difference inside and outside the water storage cylinder 210a is large, sensed by the water level meters, the buoyancy cylinder 210b can be driven to move up and down by the driving member, so as to make the water level difference inside and outside the water storage cylinder 210a consistent, thereby ensuring that the gate body 120 can drain according to the real-time water level, wherein the driving member can be a hydraulic rod or other driving member with telescopic function, the base of the hydraulic rod is fixedly arranged in the water storage cylinder 210a, and the telescopic end is connected with the bottom of the buoyancy cylinder 210b. In addition, through the mechanical linkage between the water level self-sensing mechanism 200 and the gate body 120, since the water level in the channel 110b changes, after the water levels in the channel 110b and the water storage cylinder 210a change synchronously, the height of the buoyancy cylinder 210b also changes synchronously, which indirectly drives the gap between the two gate bodies 120 to change synchronously, thereby the water level self-sensing mechanism 200 not only senses the water level to drive the gate body 120 to drain in time, but also controls the size of the opening of the gate body 120 according to the water level, that is, controls the flow of the drainage according to the drainage needs, thereby indirectly reducing the work pressure of the staff on monitoring the water level.

[0034] Embodiment 3 On the basis of Embodiment 2, with reference to Figures 1-7 The dredging mechanism 300 comprises a bearing frame 310 located at the bottom of the inner wall of the channel 110b and close to the water, a dredging assembly 320 installed on the bearing frame 310, and a second transmission assembly 330 having one end in transmission connection with the dredging assembly 320 and the other end in transmission connection with the gate body 120, the bearing frame 310 is used for conveniently installing the dredging assembly 320 and the second transmission assembly 330, and bearing the deposited sludge and impurities in the channel 110b.

[0035] In this embodiment, with reference to Figures 1-7The dredging assembly 320 comprises a reciprocating wire rod 320a located on the inner wall of the bearing frame 310, a limiting sliding rod 320b located on the inner wall of the bearing frame 310, and a dredging plate 320c which is sleeved on the limiting sliding rod 320b at one end and is threaded on the reciprocating wire rod 320a at the other end. The reciprocating wire rod 320a is used to drive the dredging plate 320c to move back and forth along the reciprocating wire rod 320a under the limiting action of the limiting sliding rod 320b when the reciprocating wire rod 320a rotates. The limiting sliding rod 320b is used to limit the dredging plate 320c, so as to avoid the synchronous rotation of the dredging plate 320c when the reciprocating wire rod 320a rotates, and thus the dredging plate 320c cannot move linearly. The dredging plate 320c is used to lift the silt and impurities deposited in the bearing frame 310 when the reciprocating wire rod 320a rotates to drive the dredging plate 320c to move reciprocally, so as to cooperate with the flowing water flow, and then the lifted silt and impurities are synchronously discharged with the water flow. The bottom sides of the dredging plate 320c are inclined surfaces, which are used to facilitate the dredging plate 320c to shovel the silt and impurities at the bottom of the bearing frame 310 when the dredging plate 320c moves, so as to avoid the silt and impurities from being unable to be cleaned in time after being agglomerated at the bottom of the bearing frame 310; With reference to Figures 1-7 The top end of the mounting frame 220a-1 has a bearing groove 310a for conveniently mounting the track wheel. The sidewall of the gate body 120 has a second sawtooth plate 120c below. When the gate body 120 moves to drive the second sawtooth plate 120c to move, the track wheel is driven to roll. The second transmission assembly 330 is a track wheel located in the bearing groove 310a and the surface sawtooth is engaged with the second sawtooth plate 120c. The drive roller of the track wheel is connected with the reciprocating wire rod 320a through the rotating shaft. When the gate body 120 moves to drive the second sawtooth plate 120c to move, the track wheel is driven to roll, and the drive roller of the track wheel rotates to drive the reciprocating wire rod 320a to rotate, and then the dredging assembly 320 is driven to work.

[0036] In this embodiment, the specific working process is as follows: when the gate body 120 moves to open, the track wheel is driven to roll along with the movement of the second sawtooth plate 120c. The drive roller of the track wheel rotates to drive the reciprocating wire rod 320a to rotate. The reciprocating wire rod 320a rotates to drive the dredging plate 320c to move reciprocally along the reciprocating wire rod 320a and the limiting sliding rod 320b under the limiting action of the limiting sliding rod 320b, so as to scrape the deposited silt and impurities in the bearing frame 310. The scraped silt and impurities are synchronously washed away with the water flow, so as to clean the deposited silt and impurities in time during the drainage process, and thus the normal drainage is not affected; In addition, after the gate body 120 moves to drive the dredging mechanism 300 to work to timely remove the deposited silt and other impurities, the deposited silt and other impurities in the channel 110b are prevented from forcing the water level in the channel 110b to be uneven, thereby preventing the water level self-induction mechanism 200 from misjudging the water level in the reservoir, and further preventing the drainage control system from being disorderly.

[0037] Embodiment 4 Based on embodiment 3, with reference to Figures 1-7 The dredging mechanism 300 further comprises an anti-blocking assembly 340 for preventing long strip impurities such as branches from being blocked between the two gate bodies 120, thereby affecting normal drainage. The top middle position of the mounting frame 220a-1 is provided with a hidden groove 310b for conveniently storing the knocking rod 340a. The anti-blocking assembly 340 comprises the knocking rod 340a installed in the hidden groove 310b through a rotating shaft and the second gear 340b located at both ends of the rotating shaft. The knocking rod 340a is used for intermittent overturning once, so as to break or squeeze out the impurities blocked between the two gate bodies 120 when overturning. With reference to Figures 1-7 The side wall of the dredging plate 320c has a third sawtooth plate 320c-1 corresponding to the second gear 340b. When the dredging plate 320c moves in the reciprocating movement, the third sawtooth plate 320c-1 is engaged with the second gear 340b at a position, thereby driving the knocking rod 340a to overturn and hit once, so as to intermittently make the knocking rod 340a overturn once to dredge between the two gate bodies 120.

[0038] In this embodiment, the specific working process is as follows: when the dredging mechanism 300 works, along with the movement of the dredging plate 320c along the reciprocating wire rod 320a and the limiting slide rod 320b, the third sawtooth plate 320c-1 is engaged with the second gear 340b at a position, thereby driving the second gear 340b to reciprocate once, so as to drive the knocking rod 340a to overturn once. The knocking rod 340a breaks or squeezes out the long strip impurities such as branches blocked between the two gate bodies 120 when overturning, thereby preventing the long strip impurities from being blocked between the gate bodies 120 to cause drainage obstruction.
