An embodiment of the present invention provides a water diversion regulation and control device, as shown in fig. 1 or fig. 2, the device includes:
the water flow control device 1 and the water flow drainage device 2;
the water flow control device 1 includes: a control unit 11 and a guide unit 12;
the control unit 11 includes: a box-type frame 111, a water level control module 112 and a water quantity control module 113;
the water level control module 112 is positioned in the box-type frame 111, and the water quantity control module 113 is connected with the box-type frame 111;
the guide unit 12 is communicated with the box-type frame body 111;
the box-type frame body 111 is provided with a water outlet, and the water flow guiding device 2 is communicated with the box-type frame body 111 through the water outlet.
The device provided by the embodiment of the invention at least has the following technical effects:
according to the device provided by the embodiment of the invention, the water flow guiding device 2 is used for guiding the flood water in the drainage channel into the pond weir through the water outlet on the box-type frame body 111. The water level of the flood water entering the pond weir is controlled by the water level control module 112, and the water amount of the flood water entering the pond weir is controlled by the water amount control module 113, so that the flood water in the drainage channel is treated. When the water in the pond weir is fully stored and does not need to be stored or the drainage channel does not need to be drained, whether flood water enters the pond weir or not or the quantity of the water entering the pond weir can be controlled by the water level control module 112 and the water quantity control module 113. The dynamic distribution and regulation of the water quantity of the drainage channel and the small reservoir are realized, and the flooding phenomenon of the small reservoir can be avoided. Through the dual control to water level and water yield, can effectively subdue the flood control and the pressure of removing the waterlogging of escape canal, realized according to the automatic function to the pond weir reposition of redundant personnel flood waterlogging of escape canal water level and velocity of flow variation.
The water diversion regulating device provided by the embodiment of the invention is further described by the optional embodiment.
Alternatively, the flow control module 1 may be located in a drain channel and the flow diversion apparatus 2 may be located in an impoundment weir. The embodiment of the invention provides an example, a water flow control module 1 is placed in a drainage channel, a water flow guiding device 2 is placed in an pond weir, and water quantity in the drainage channel and the pond weir is controlled by the water quantity diversion and control device provided by the embodiment of the invention.
Optionally, the water diversion regulation and control device provided by the embodiment of the invention can also be used for water quantity regulation and control in other places, and the embodiment of the invention is not limited.
Alternatively, as shown in fig. 3, the water level control module 112 includes: the control plate 1121 includes a control groove in the box-type housing 111, and the control plate 1121 is positioned in the control groove.
Considering that the control plate 1121 is inserted into the control groove to realize different water inlet level control, when the height of the control plate 1121 needs to be adjusted, the control plate 1121 is pulled out from the control groove to replace the control plate 1121 with a new one. By providing the inner diameter of the control groove slightly larger than the thickness of the control plate 1121, it is avoided that the control plate 1121 is difficult to be pulled out because the gap of the control groove is too small when the control plate 1121 is pulled out.
In use, the water level in the drainage channel may change due to the intensity of rainfall or the change in conditions of the bottom of the drainage channel, and the control water level at which the drainage channel drains the flooded water into the weir needs to be adjusted.
It is understood that the height of the control plate 1121 cannot exceed the height of the box frame 111 at the highest.
As an example, when the water level of the drainage channel for draining the flood water into the weir is reset, the height of the control plate 1121 may be selected according to the required water level. For example, the height of the box frame 111 is 1m, the height of the water level to be discharged into the pond is 0.2m, and the height of the control plate 1121 may be selected to be 0.8 m. The newly selected control plate 1121 is inserted into the control slot, and the control plate 1121 and the box-type frame 111 are fixed by the locking mechanism.
Considering that the control plate 1121 controls the water level, when the content of the flood water is large, the flood water generates a large impact force, and therefore, the control plate 1121 needs to be a plate having a certain strength. For example, the control plate 1121 may be a plate made of stainless steel, or a plate with a certain strength. The stainless steel plate is selected, so that the weight of the box-type frame body 111 can be reduced, and the box-type frame body 111 can be mounted and placed in a drainage channel conveniently. In addition, the stainless steel plate can avoid long-term soaking in water, corrosion, rusting and the like. When the control plate 1121 needs to be replaced due to rainfall or other factors, the control plate 1121 can be better pulled out from the control slot for replacement.
Optionally, the control panel 1121 has a handle thereon. By providing a handle on the top of the control plate 1121, the control plate 1121 can be lifted out of the control slot by lifting up the handle when the control plate 1121 is replaced.
Optionally, the water level control module 112 further comprises: and one end of the locking mechanism is connected with the box-type frame 111, and the other end of the locking mechanism is connected with the control plate 1121.
Considering that when the control plate 1121 is located in the control groove, the control plate 1121 may loosen or collapse in the control groove due to the limited depth of the control groove, and the control plate 1121 is further fixed and limited by the locking mechanism.
For example, the locking mechanism may be a buckle, one end of which is connected to the box-type frame 111, and the other end of which is connected to the control plate 1121. The number of the fasteners may be multiple, and the two ends of the control plate 1121 are connected to the box-type frame 111 through the multiple fasteners, so as to prevent the control plate 1121 from moving or collapsing in the control slot.
Optionally, the water level control module 112 further comprises: and the sealing piece is positioned in the control groove and used for sealing between the control plate 1121 and the control groove.
Considering that the control plate 1121 is inserted into the control groove, flood water may leak through the gap of the control groove, resulting in inaccurate water level control. The sealing element is arranged to seal between the control panel 1121 and the control groove, so that water leakage caused by flood water passing through a gap between the control panel 1121 and the control groove is avoided.
The sealing element may be a sealing ring or a sealing gasket, for example.
Alternatively, as shown in fig. 4, the water amount control module 113 includes: the gate 1131, the elastic connecting piece 1132, the first pulley 1133, the weighting piece 1134, the rotary paddle 1135, the first connecting rope 1136, the second connecting rope 1137, the support bar 1138 and the second pulley 1139;
one end of the elastic connecting piece 1132 is connected with the gate 1131, and the other end is connected with two ends of the end cover of the box-type frame body 111; the first pulley 1133 is connected with the top of the end cover of the box-type frame 111, one end of the first connecting rope 1136 passing through the first pulley 1133 is connected with the gate 1131, and the other end is connected with the weighting piece 1134;

The water quantity control module 113 works as follows:
as shown in fig. 5, during the application, because revolve thick liquid 1135 and be located the flood water in the drainage canal, when rainfall increase, or when the discharge of water in the drainage canal is great, rivers will promote to revolve thick liquid 1135 and rotate, revolve thick liquid 1135 when rotating, connect rope 1137 through the second of winding on revolving thick liquid 1135 thick liquid hub, the mechanical energy when will revolve thick liquid 1135 and rotate transmits gate 1131, second is connected rope 1137 and is driven gate 1131 upward movement, gate 1131 is opened, the flood water is discharged through the delivery port after second region gets into the third region. When the water drainage is not required, the shutter 1131 moves downward by the elastic coupling member 1132 and its own weight, and stops when it moves to a position equal to the weight of the weight 1134.
Considering that the gate 1131 has its own weight, the embodiment of the present invention balances the weight of the valve 1131 by providing the weighting member 1134 at the other end of the first connecting rope 1136, so as to prevent the mechanical energy generated by the rotation of the propeller 1135 from pulling up the gate 1131 when the water flow rate is not large enough, and thus the purpose of draining water is not achieved.
It will be appreciated that the weight of the weight 1134 is comparable to the weight of the gate 1131, i.e., the weight of the weight 1134 may be equal to the weight of the gate 1131, or may be slightly greater than or less than the weight of the gate 1131. Illustratively, the weight 1134 may be an iron block or the like having the same weight as the shutter 1131. As long as the gravity balance with the gate 1131 can be achieved.
The resilient coupling 1132 may be a snap-fit or hinged connection to the gate 1131.
Considering that there is no connection place on the gate 1131 when the first connection string 1136 is connected to the gate 1131, a connection hole is formed on the connection member by providing the connection member on the gate 1131, and the first connection string 1136 passes through the connection hole to be connected to the gate 1131. For example, the connecting member may be a connecting rod having a ring-shaped connecting hole at an upper end thereof, and the connecting rod may be welded to the gate 1131, or may be screwed to the gate.
The connecting member may be provided at any position of the gate 1131, but is provided at an intermediate position of the gate 1131, which is more labor-saving in lifting the gate 1131. The first pulley 1133 may be provided at any position of the cover plate of the box-shaped housing 111 above the third area, but is provided at the middle of the cover plate of the box-shaped housing 111 above the third area, that is, at a position facing the connector, and is provided at another position, so that the force for lifting up the shutter 1131 is smaller.
Optionally, the water level control module 112 and the gate 1131 sequentially divide the box-type frame 111 into a first area, a second area and a third area;
the flow guide unit 12 is communicated with the first area; the water outlet is positioned in the third area of the box-type frame body 111.
The box-type frame body 111 provided by the embodiment of the invention is a frame body with a certain volume, the frame body is provided with an upper end cover, flood water enters the box-type frame body 111 through the flow guide unit 12, and the water level of the flood water flowing into the pond weir is controlled through the water level control module 112 in the box-type frame body 111.
The water level control module 112 and the gate 1131 sequentially divide the box-type frame 111 into a first region, a second region and a third region. The water conservancy diversion unit 12 communicates with the first region, and in the flood water in the drainage channel got into the first region through water conservancy diversion unit 12 promptly, through the water level in the water level control module 112 control entering second region, through the water yield of gate 1131 control entering third region, flood water in the third region flows out through the delivery port on the box framework 111.
Alternatively, the box-type frame 111 provided by the embodiment of the present invention may be a square frame or a rectangular frame. When the box-type frame 111 is a rectangular parallelepiped or square frame, the water level control module 112 and the gate 1131 are adapted to the size and structure of the box-type frame 111.
When the box frame 111 is a square frame, the size of the square box frame 111 may be a frame having a length, width and height of 1 m. When the box frame 111 is a rectangular parallelepiped frame, the rectangular parallelepiped frame may have a length of 1m, a width of 0.5m, and a height of 1 m. The size of the box-type frame 111 is not limited, and may be determined according to the size of the on-site drainage channel or the size of the weir in actual use.
The box-type frame 111 can be made of stainless steel, and the frame made of the stainless steel frame can avoid corrosion in water and influence on the service life of equipment.
The box-type frame body 111 can be installed in a drainage channel in a detachable connection mode, and is convenient to detach and replace when equipment breaks down or is damaged. For example, the device may be bolted to the inner slope of the drain channel.
Optionally, a gate slot is provided in the box frame 111, and the gate 1131 is located in the gate slot.
Optionally, the support rods include a horizontal connecting rod and a vertical connecting rod connected in sequence, the vertical connecting rod is connected to the rotary paddle 1135, and the horizontal connecting rod is connected to the frame edge of the box-type frame 111. A second pulley 1139 is located at the junction of the horizontal connecting bar and the vertical connecting bar. The second connecting rope 1137 is wound around the second pulley 1139, and has one end wound around the hub of the rotary paddle 1135 and the other end connected to the gate 1131. When the blades of the propeller 1135 rotate, the blades transmit mechanical energy to the hub of the propeller, and the second connecting rope 1137 wound on the hub is driven to move by the rotation of the hub, so that the gate 1131 is pulled up.
Optionally, the elastic connection element 1132 is selected according to an elastic coefficient; the elastic coefficient of the elastic coupling member 1132 is obtained by the following equation:
wherein K is the elastic coefficient of the elastic connecting member 1132, Δ L is the maximum opening distance of the gate 1131, and VmaxIs the minimum flow velocity of channel water flow at the maximum opening distance of the gate, VminThe flow velocity of channel water flow is started when the gate is just opened, and theta is a velocity coefficient.
When the rainfall amount is increased or decreased, the water amount can be controlled by changing the elastic connecting piece 1132, and then controlling the rising or falling opening degree of the gate 1131.
For example, the minimum flow velocity V of water flow in the water channel at the maximum opening distance of the gate 1131 can be determined according to the actual requirements of the application areamaxChannel water flow starting flow velocity V just after the gate 1131 is openedminThe speed coefficient is obtained from empirical parameters in actual operation.
Illustratively, the maximum opening distance of the gate 1131 is to lift the gate 1131 to the top of the box frame 111, i.e., the presence of the gate 1131 does not affect the water flow rate in the box frame 111.
Minimum flow velocity V of channel water flow at maximum opening distance of gate 1131maxCan be obtained by opening the gate 1131 a maximum distanceThe minimum flow rate of the channel water flow when the gate 1131 is opened for the maximum distance is obtained by averaging the channel water flow rates close to the minimum flow rate, for example, 2, 3, 4, etc.
The flow velocity of the channel water flow close to the minimum flow velocity may be selected according to the terrain or the environmental factors, and the specific situation is determined according to the actual environment and situation during operation, which is not limited in the embodiment of the present invention.
Channel water flow starting velocity V when gate 1131 is just openedminThis is the flow rate at which channel water begins to pass through the gate 1131 when the gate 1131 is opened from a closed position until a maximum opening distance is reached. For example, when the gate 1131 is opened from the closed state and reaches the maximum opening distance at the time of 12:00:01, the flow rate at which the channel water flow starts to pass through the gate 1131 at the time of 12:00:01 is taken as the channel water flow starting speed at the time when the gate 1131 is just opened.
For example, the elastic modulus of each of the selectable elastic connectors is obtained in a manner that the elastic modulus of the elastic connector 1132 is obtained as above, and then one elastic connector is selected for use in the opening or lifting process of the shutter 1131 according to the elastic modulus of each of the selectable elastic connectors.
Alternatively, as shown in fig. 1 or 2, the water flow diversion device 2 comprises: a draft tube 21 and a float 22; one end of the draft tube 21 is communicated with the water outlet, the other end is positioned in the pond weir, the floating piece 22 is connected with the draft tube 21, and the floating piece 22 is used for preventing the draft tube 21 from sinking into the bottom of the pond weir and floating on the surface of the pond weir.
The device provided by the embodiment of the invention needs to drain the redundant flood water in the drainage channel to a nearby pond weir, and the drainage tube 21 is arranged to be connected with the water outlet on the box-type frame 111, so that the flood water is led to the pond weir.
Considering that the draft tube 21 is always located at the bottom of the pond weir, the sludge at the bottom of the weir blocks the draft tube 21 with the lapse of time, resulting in the failure of the apparatus to discharge water normally. Therefore, draft tube 21 provided in the embodiment of the present invention is a soft tube, and does not sink to the bottom of the weir because the soft tube is light in weight. Considering that the drainage tube 21 is frequently exposed to the water surface, the floating materials on the water surface block the drainage tube 21, resulting in abnormal drainage of the apparatus. By providing the floating member 22 connected to the draft tube 21, the floating member 22 can float on the water surface, so that the floating member 22 can bring the draft tube 21 above the bottom of the weir by its own buoyancy without being completely exposed to the water surface.
For example, the drainage tube 21 may be a tube made of rubber. The float 22 may be a floating plate or the like.
The length of the draft tube 21 is determined according to the distance between the drain channel and the weir when applied. The present embodiment is not limited.
Alternatively, as shown in fig. 2, the guide unit 12 includes: a first flow guide frame body 121 and a second flow guide frame body 122 which are sequentially communicated;
the first diversion frame body 121 is positioned at the bottom of the drainage channel, and the second diversion frame body 122 is communicated with the box-type frame body 111;
the first diversion frame 121 has a water inlet.
Optionally, the number of the water inlet holes is determined according to the size of the first diversion frame body 121, and the number of the water inlet holes may be multiple.
The first flow guiding frame body 121 and the second flow guiding frame body 122 may be box-shaped frame bodies, the first flow guiding frame body 121 is provided with water inlet holes, when the flood water level in the drainage channel is too high, the first flow guiding frame body 121 and the second flow guiding frame body 122 are submerged in water, and the water enters the first flow guiding frame body 121 through the water inlet holes and enters the box-shaped frame body 111 through the second flow guiding frame body 122. Through setting up first water conservancy diversion framework 121 to set up the inlet opening on first water conservancy diversion framework 121, can avoid in debris entering first water conservancy diversion framework 121 of aquatic, and then block up the water conservancy diversion passageway, influence the emission of flood waterlogging.
For example, the first flow guiding frame body 121 may be a rectangular parallelepiped or a rectangular parallelepiped, and when the first flow guiding frame body 121 is a rectangular parallelepiped or a rectangular parallelepiped, the second flow guiding frame 122 is a frame body adapted to the first flow guiding frame body 121.
Considering that the water in the drainage channel enters the box-type frame 111 through the water inlet holes of the first diversion frame 121, the water inlet rate is increased and the drainage efficiency is improved by setting a plurality of water inlet holes. Considering that a part of impurities can be prevented from entering the box-type frame body 111 through the water inlet hole, the impurities are prevented from blocking the flow guide channel. The diameter of the water inlet hole cannot be too large, the water inlet hole cannot be too large to achieve the purpose of blocking sundries, and the water inlet hole cannot be too small, so that the water discharging efficiency can be reduced. Illustratively, the diameter of the water inlet opening may be 10-20 mm. For example, it may be 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, 19mm, 20mm, or the like.
Alternatively, as shown in fig. 2, the second baffle frame body 122 is connected to the first baffle frame body 121 in an upward inclined slope.
In consideration of the fact that the drainage is not required when the amount of water in the drainage channel is small, the embodiment of the present invention provides an example that the second flow guiding frame body 122 is connected to the second flow guiding frame body 121 in an upward slope manner by forming an included angle between the second flow guiding frame body 122 and the second flow guiding frame body 121, and only when the flood level in the drainage channel is higher than that of the second flow guiding frame body 122, the flood can be drained from the drainage channel to the weir.
As an example, the slope between the second pick-up frame body 122 and the first pick-up frame body 121 may be 90 ° -120 °. Illustratively, it may be 90 °, 95 °, 100 °, 105 °, 110 °, 115 °, 120 °, etc.
Optionally, the first diversion frame 121 and the second diversion frame 122 are connected in a downhill manner, and the amount of water entering the box-type frame 111 is controlled by the height of the first diversion frame 121. For example, when the water level in the drain channel exceeds the height of the first baffle frame 121, water may enter the box frame 111 through the second baffle frame 122. Thus, the water level in the drain channel can be controlled to be lower than the height of the first guide frame body 121, and the water in the drain channel can be prevented from being discharged. And partial sundries in the drainage channel can be prevented from entering the box-type frame body 111 to block the flow guide channel, so that long-term effective operation of the equipment is ensured.
All the above optional technical solutions may be combined arbitrarily to form the optional embodiments of the present disclosure, and are not described herein again.
The above description is only an illustrative embodiment of the present invention, and should not be taken as limiting the scope of the invention, and any modifications, equivalents, improvements and the like that are within the spirit and principle of the present invention should be included in the scope of the present invention.
