The top wall of the adjusting shell is upwards connected with an upper ear seat which is connected with an upper steel wire rope; the bottom wall of the adjusting shell is downwards connected with a lower ear seat which is connected with a lower steel wire rope.
The invention has the following advantages:
The invention establishes the association between the water level of the main water tank and the opening degree of the butterfly valve, and the opening degree of the butterfly valve is smaller and is closed as the water level of the main water tank is higher; conversely, the higher the main tank level, the greater the butterfly valve opening and up to full opening. Thus, the flow of the water replenishing gradually changes along with the change of the water level of the main water tank, and the lower the water level of the main water tank is, the larger the water replenishing amount is.
In the prior art, the water level of the water tank is controlled by setting an upper water level and a lower water level, and when the water level in the water tank is reduced to the lower water level, water supplementing is started, the water level is directly supplemented to the upper water level once the water supplementing process is started, and then water supplementing is stopped. And along with continuous water outlet of the water tank, when the water level drops to the lower water level again, the next water supplementing process is started again. Thus, the water replenishing related components can frequently act, and the service life of the water replenishing components (such as a valve or a water replenishing pump) is shortened.
The invention can achieve dynamic balance between the water outlet and the water supplementing of the main water tank, and when the opening degree of the butterfly valve enables the water outlet and the water supplementing of the main water tank to achieve dynamic balance, the stable water level can be formed in the main water tank. As long as the water output of the main water tank does not change, the water level of the main water tank can be kept unchanged through dynamic water supplementing. After the water yield of the main water tank changes, the opening degree of the butterfly valve on the water supplementing pipe is automatically increased or reduced, so that the water supplementing amount and the water yield of the main water tank keep dynamic balance, the water level in the main water tank does not need to continuously oscillate between the upper water level and the lower water level as in the prior art, the water supplementing part does not need to frequently act, the water supplementing operation is simplified, and the service life of the water supplementing part such as the butterfly valve is prolonged.
The water yield of the main water tank represents the downstream water load, and the invention can achieve dynamic balance between the main water tank and the downstream water load, so that the water supplementing quantity (water supplementing speed) of the water tank is automatically adapted to the downstream water load.
The pulley transmission device is simple in structure, and can convert the up-and-down floating of the regulating box into the swing of the turntable, and then into the swing of the valve rod of the butterfly valve, so that the opening degree of the butterfly valve is controlled.
The structure of the adjusting device has the advantage of being very convenient for transportation. In principle, the whole density of the adjusting device is smaller than that of water, so that the adjusting device can float in the water. In addition, the adjusting device has certain weight to pull the upper steel wire rope to move downwards under the action of gravity. If the weight of the adjusting device is heavy, the adjusting device is laborious, energy-consuming and consumes more materials during manufacture, transportation, handling and assembly. The invention sets the adjusting device as a hollow box body, which has the advantages of greatly reduced weight, less consumption of materials, and labor and energy saving during manufacture, transportation, carrying and assembly.
After the invention is assembled, when the invention is used, water in the regulating box enters the water chamber through the water inlet hole, thereby increasing the weight of the regulating device, and when the water level of the main water tank is lowered (the water level in the regulating box is lowered synchronously), the regulating device can pull the upper steel wire rope downwards more forcefully under the action of gravity.
The regulating box is a newly added structure, the smaller the volume is, the smaller the influence on the original equipment of the water treatment system is, the more convenient the installation is, and the equipment cost is lower. The split structure of the adjusting box is convenient to install and can be stably supported on the ground when a smaller section is adopted.

The water level regulating mechanism comprises a regulating box, a regulating device with overall density smaller than that of water is arranged in the regulating box, and the regulating device floats on the water surface in the regulating box; the cross-sectional area of the regulating tank is smaller than that of the main water tank 1;
The bottom of the regulating box is connected with the main water tank 1 through a communicating pipe 6, and the regulating box is as high as the main water tank 1; the top end of the adjusting device is connected with an upper steel wire rope 18, the bottom end of the adjusting device is connected with a lower steel wire rope 19, the upper steel wire rope 18 and the lower steel wire rope 19 are in transmission connection with the valve rod 5 through a pulley transmission device, and when the adjusting device rises along with the water level in the adjusting box, the upper steel wire rope 18 and the lower steel wire rope 19 drive the valve rod 5 to rotate through the pulley transmission device and reduce the opening degree of the butterfly valve 3 until the butterfly valve 3 is closed; when the adjusting device descends along with the water level in the adjusting box, the upper steel wire rope 18 and the lower steel wire rope 19 drive the valve rod 5 to rotate through the pulley transmission device, and the opening degree of the butterfly valve 3 is increased until the butterfly valve 3 is completely opened.
The pulley transmission device comprises an upper fixing frame 20, a lower fixing frame 21, a turntable 22, a large pulley 23, a small pulley 24 and a bottom pulley 25; the top of the side wall of the adjusting box is fixedly connected with the upper fixing frame 20 upwards, the small pulley 24 is arranged in the middle of the upper fixing frame 20, and the small pulley 24 is higher than the adjusting box; the top of the upper fixing frame 20 is provided with a large pulley 23, and the axes of the large pulley 23, a small pulley 24 and the turntable 22 are parallel to each other;
The rotary table 22 is arranged on the lower fixing frame 21, and the lower fixing frame 21 is positioned on the ground at one side of the adjusting box and is adjacent to the water supplementing pipe 2; the water supplementing pipe 2 is provided with a butterfly valve 3, the butterfly valve 3 is provided with a valve rod 5, the valve rod 5 is provided with a rotation center, and the valve rod 5 is rotated to control the opening and closing and the opening degree of the butterfly valve 3; the turntable 22 is provided with a valve rod clamping groove 27, the valve rod 5 is clamped in the valve rod clamping groove 27, and the axis of the turntable 22 passes through the rotation center of the valve rod 5;
The bottom pulley 25 is arranged at the bottom position in the adjusting box through the bottom fixing frame 26, and the lower steel wire rope 19 downwards bypasses the bottom pulley 25, upwards extends along a gap between the adjusting device and the inner wall of the adjusting box, and downwards is connected with the left side of the turntable 22 after bypassing the small pulley 24; the other side, right side, of the turntable 22 is connected with an upper steel wire rope 18, and the upper steel wire rope 18 upwards bypasses a large pulley 23, then downwards extends into the adjusting box and is connected with the top end of the adjusting device.
The adjusting device comprises a hollow adjusting shell 13, a horizontal partition plate 14 is arranged in the middle of the adjusting shell 13, the partition plate 14 and the adjusting shell 13 below the partition plate enclose a water chamber 15, the partition plate 14 and the adjusting shell 13 above the partition plate enclose a cavity 17, and a row of water inlet holes 16 are formed in the side wall of the top of the water chamber 15 along the circumferential direction; the bottom of the water chamber 15 is connected with the communicating pipe 6. The cavity 17 has the function of increasing the buoyancy, and can conveniently ensure that the buoyancy force suffered by the invention in water is larger than the static friction force of the valve rod 5 of the butterfly valve.
The structure of the adjusting device has the advantage of being very convenient for transportation. In principle, the whole density of the adjusting device is smaller than that of water, so that the adjusting device can float in the water. In addition, the adjusting device has a certain weight to pull the upper wire rope 18 to move downwards under the action of gravity. If the weight of the adjusting device is heavy, the adjusting device is laborious, energy-consuming and consumes more materials during manufacture, transportation, handling and assembly. The invention sets the adjusting device as a hollow box body, which has the advantages of greatly reduced weight, less consumption of materials, and labor and energy saving during manufacture, transportation, carrying and assembly.
After the invention is assembled, in use, water in the regulating tank enters the water chamber 15 through the water inlet hole 16, so that the weight of the regulating device is increased, and when the water level of the main water tank 1 is lowered (the water level in the regulating tank is synchronously lowered), the regulating device can pull the upper steel wire rope 18 downwards more forcefully under the action of gravity.
The adjusting box is divided into a main box section 7 positioned at the upper part and a supporting box section 8 positioned at the lower part, and the supporting box section 8 is arranged on the ground through a supporting seat 9; the supporting box section 8 is fixedly connected with the main box section 7 in a sealing way through a flange structure 10.
The top wall of the adjusting shell 13 is upwards connected with an upper ear seat 11, and the upper ear seat 11 is connected with an upper steel wire rope 18; the bottom wall of the adjusting shell 13 is downwards connected with a lower ear seat 12, and the lower ear seat 12 is connected with a lower steel wire rope 19.
The regulating box is a newly added structure, the smaller the volume is, the smaller the influence on the original equipment of the water treatment system is, the more convenient the installation is, and the equipment cost is lower. The split structure of the adjusting box is convenient to install and can be stably supported on the ground when a smaller section is adopted.
In operation, the main tank 1 continuously supplies water to downstream water units through the water outlet pipe 4, and the downstream water load changes along with the actual situation. When the water consumption of the downstream increases and the water output of the water outlet pipe 4 increases, the water level in the main water tank 1 decreases. Since the regulating tank and the main water tank 1 are communicated with each other, the water level in the regulating tank is also lowered synchronously, so that the regulating device floating in the regulating tank is lowered with the water level. The weight of the adjusting device is greater than the static friction of the valve stem 5 of the butterfly valve 3, so that when the adjusting device moves downwards, the upper wire rope 18 pulls the turntable 22 upwards on the right side of the drawing, so that the turntable 22 rotates anticlockwise. The force pulling the turntable 22 to rotate at this time is actually the weight of the regulating device and the water contained therein. When the turntable 22 rotates anticlockwise, the lower wire rope 19 is driven, so that the lower wire rope 19 moves along the bottom pulley 25 and the small pulley 24 and maintains a tensioning state.
When the turntable 22 rotates anticlockwise, the valve rod 5 of the butterfly valve 3 is driven to rotate, and the opening degree of the butterfly valve 3 is increased. If the main tank 1 level drops continuously, the butterfly valve 3 will eventually be fully opened. If the water level of the main water tank 1 is not lowered after the opening degree of the butterfly valve 3 is increased to a certain degree, the water supplementing and water discharging reach dynamic balance, the water level is not changed, and the opening degree of the butterfly valve 3 is correspondingly stabilized.
When the water load in the downstream is reduced, the water level in the main tank 1 and the regulating tank rises, and when the regulating device moves upward, the lower wire 19 pulls the illustrated left side of the turntable 22 upward, so that the turntable 22 rotates clockwise. The force pulling the turntable 22 to rotate at this time is actually the upward buoyancy force to which the adjusting means is subjected due to the rise of the water level. The buoyancy force experienced by the regulator when immersed in water is greater than the static friction force of the valve stem 5 of the butterfly valve 3. When the turntable 22 rotates clockwise, the upper wire rope 18 is driven, so that the upper wire rope 18 moves along the large pulley 23 and maintains a tensioned state.
When the turntable 22 rotates clockwise, the valve rod 5 of the butterfly valve 3 is driven to rotate and the opening degree of the butterfly valve 3 is reduced. If the main tank 1 level is rising continuously (i.e. the downstream load is decreasing continuously), the butterfly valve 3 will eventually close completely. If the water level of the main water tank 1 does not rise after the opening degree of the butterfly valve 3 is reduced to a certain degree, the water supplementing and water discharging reach dynamic balance, the water level is not changed, and the opening degree of the butterfly valve 3 is correspondingly stabilized.
The water level of the main water tank 1 is the lower limit water level when the butterfly valve 3 is fully opened, the water level of the main water tank 1 is the upper limit water level when the butterfly valve 3 is fully closed, the dynamic balance of water outlet and water supplementing can be achieved at any point between the upper limit water level and the lower limit water level, the water supplementing is not required to be started when the water level is lowered to the lower limit water level as in the prior art, the water supplementing is completely stopped when the water level is raised to the upper limit water level, and compared with the prior art, the water supplementing process is more uniform and stable, and the water supplementing device can automatically adapt to downstream water loads.
The above embodiments are only for illustrating the technical solution of the present invention, and it should be understood by those skilled in the art that although the present invention has been described in detail with reference to the above embodiments: modifications and equivalents may be made thereto without departing from the spirit and scope of the invention, which is intended to be encompassed by the claims.
