Description

Technical Field

[0001] The present invention relates to the technical field of energy conservation and environmental protection, and more specifically, to a water hammer pump system. Background Art

[0002] The water hammer pump body includes a water discharge valve, a water delivery valve, a pressure tank and a main pipeline. The water discharge valve and the water delivery valve are both check valves. The main pipeline has a water inlet, a first interface and a second interface. The pressure tank has a third interface and a water lifting port. The water discharge valve is installed at the first interface, and the water delivery valve connects the second interface and the third interface. The wall of the second interface has an air inlet.

[0003] The water hammer pump is an automatic water pumping machine that uses the power of flowing water to produce a water hammer effect under the mechanical action of two check valves (the two check valves are the drain valve and the water delivery valve), lifting water from a low place to a high place. The water hammer pump does not consume energy such as coal, oil and electricity, is economical and practical, and has good ecological and environmental benefits. Specific work projects include: In the initial state, the drain valve is in an open state due to the gravity of its valve disc assembly, and the water delivery valve is in a closed state due to the gravity of its valve disc assembly. Under the action of the water level difference, the water in the upper pool is supplied into the main pipeline from the water inlet through the power water pipe, and is discharged through the drain valve and falls into the tailwater pool. When the water flow in the power water pipe is accelerated to a flow rate exceeding a certain critical value, so that the thrust of the water flow in the power water pipe is greater than the gravity of the valve disc assembly of the drain valve, the thrust of the water flow in the power water pipe pushes the valve disc assembly of the drain valve to operate and close the drain valve. Due to the sudden closure of the drain valve, a violent water hammer effect occurs inside the main pipeline and the pressure increases rapidly, causing the valve disc assembly of the water delivery valve to operate and open the water delivery valve, and the water in the main pipeline flows into the pressure tank through the water delivery valve. At this time, the air in the pressure tank is compressed and the pressure increases, the water in the main pipeline decreases and the pressure decreases, so that the valve flap assembly of the water supply valve is reset and the water supply valve is closed again, and the valve flap assembly of the water discharge valve is reset and the water discharge valve is opened again, and the water hammer pump body enters the next working cycle. This cycle is repeated to achieve continuous water discharge from the water lift port.

[0004] Among them, the water in the main pipeline in the previous cycle enters the pressure tank, and negative pressure is formed at the second interface in the main pipeline. The outside air is sucked into the main pipeline from the air inlet, and in the next cycle, it flows into the pressure tank together with the water in the main pipeline to replenish the air in the pressure tank that is dissolved and discharged by the water in the pressure tank.

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other arbitrarily without conflict.

[0026] The water hammer pump system provided by the embodiment of the present invention is as follows: Figure 1 , Figure 2 and Figure 5 As shown, it includes: a water hammer pump body 100, the water hammer pump body 100 includes a main pipeline, a drain valve 120, a water delivery valve 130 and a pressure tank 140, the main pipeline includes a main pipe 111 and a third branch pipe 112 connected to each other, the main pipe 111 has a water inlet, a first interface and a second interface, the third branch pipe 112 has a third interface and a fourth interface, the drain valve 120 is arranged at the first interface, and the pressure tank 140 and the water delivery valve 130 are arranged at the second interface; a first check valve 200, the first check valve 200 is arranged at the third interface and is arranged to be conducted from the outside to the inside of the third branch pipe 112; an air pressure drive device 400 and a second check valve 300, the air pressure drive device 400 is connected to the fourth interface through the second check valve 300, and the second check valve 300 is arranged to be conducted from the inside of the third branch pipe 112 to the air pressure drive device 400; When the drain valve 120 is closed, the liquid level inside the third branch pipe 112 rises, the first one-way valve 200 is closed, and the second one-way valve 300 is opened to supply air from the inside of the third branch pipe 112 to the air pressure driving device 400 (such as Figure 4 shown); When the drain valve 120 is opened, the liquid level inside the third branch pipe 112 drops, the first one-way valve 200 is turned on and air is supplied from the outside to the inside of the third branch pipe 112, and the second one-way valve 300 is turned off (such as Figure 3 as shown).

[0027] When the water hammer pump system is in use, the upper end of the third branch pipe 112, the third interface and the fourth interface are all located above the liquid level of the water in the upper pool 700. The water of the upper pool 700 is continuously supplied to the main pipe 111 from the water inlet, and the drain valve 120 is used to drain water. When the thrust of the water flow in the main pipe 111 drives the valve flap assembly of the drain valve 120 to operate and close the drain valve 120, the drain valve 120 will stop draining water, and a severe water hammer effect will occur inside the main pipeline and the pressure will increase rapidly. This pressure not only causes the valve flap assembly of the water delivery valve 130 to operate and open the water delivery valve 130, so that the water inside the main pipeline flows from the water delivery valve 130 into the pressure tank 140, but also causes the liquid level in the third branch pipe 112 to rise, so that the gas above the liquid level in the third branch pipe 112 is supplied from the second one-way valve 300 to the air pressure drive device 400. In this process, the first one-way valve 20 0 is cut off; after the water hammer effect ends, not only the valve flap assembly of the water discharge valve 120 is reset and the water discharge valve 120 is opened again, so that the water discharge valve 120 continues to discharge water, the valve flap assembly of the water delivery valve 130 is reset and the water delivery valve 130 is closed, but also the liquid level in the third branch pipe 112 is lowered, so that the external gas is replenished from the first one-way valve 200 to the liquid level above the third branch pipe 112, and the second one-way valve 300 is cut off during this process; therefore, when the water hammer pump body 100 is continuously running, the liquid level in the third branch pipe 112 will rise and fall periodically, the first one-way valve 200 will replenish gas periodically to the liquid level above the third branch pipe 112, and the second one-way valve 300 will supply gas periodically to the air pressure drive device 400, so that not only the pressure tank 140 can continuously lift water, but also the air pressure drive device 400 can continuously operate. Among them, the number 800 is a high-level water tank.

[0028] The third branch pipe 112, the first one-way valve 200, the air pressure drive device 400 and the second one-way valve 300 may comprise a group; or the third branch pipe 112, the first one-way valve 200, the air pressure drive device 400 and the second one-way valve 300 may comprise a plurality of groups, which may be two groups, three groups, four groups, etc.; the third branch pipe 112 may be a straight pipe, or the third branch pipe 112 may be a folded pipe comprising a horizontal section and a vertical section, the vertical section being located on one side of the main pipe 111, and the lower end of the vertical section being connected to the main pipe 111 through the horizontal section), etc.; all of the above may achieve the purpose of the present application, and the purpose thereof does not deviate from the design concept of the present invention, and will not be repeated here, and all shall fall within the protection scope of the present application.

[0029] In some examples, such as Figures 1 to 5As shown, the main pipe 111 includes a transverse pipe, a first branch pipe and a second branch pipe, the first branch pipe and the second branch pipe are both located on the upper side of the transverse pipe and are both connected to the transverse pipe at their lower ends, the water inlet is located at one end of the transverse pipe, the first interface is located at the top of the first branch pipe, the second interface is located at the top of the second branch pipe, the third branch pipe 112 is also located on the upper side of the transverse pipe and is connected to the transverse pipe at its lower end, and the third interface and the fourth interface are both located on the upper side wall (or top wall) of the third branch pipe 112. Among them, the first branch pipe, the second branch pipe and the third branch pipe 112 are all vertically arranged in the up-down direction, the valve flap assembly of the drain valve 120 performs periodic reciprocating movements in the up-down direction, and the valve flap assembly of the water delivery valve 130 also performs periodic reciprocating movements in the up-down direction.

[0030] The third branch 112 may be located between the first branch and the second branch; or the second branch may be located between the first branch and the third branch 112; or the first branch may be located between the second branch and the third branch 112, etc.; all of the above can achieve the purpose of the present application, and their purpose does not deviate from the design concept of the present invention, and will not be repeated here, and all should fall within the protection scope of the present application.

[0031] In some embodiments, Figure 1 , Figure 2 and Figure 5 As shown, the transverse pipe includes a first pipe and a power pipe that are connected, and the axes of the first pipe and the power pipe intersect vertically or obliquely, such as the power pipe extends obliquely upward from an end adjacent to the first pipe to an end away from the first pipe (that is, the axes of the first pipe and the power pipe intersect obliquely), the water inlet is located at the end of the power pipe away from the first pipe, the second branch pipe is located between the first branch pipe and the third branch pipe 112, and the first branch pipe and the second branch pipe are both connected to the first pipe. It can be that the first branch pipe is set as an elbow, and the elbow is connected to the end of the first pipe away from the power pipe. It can be that the third branch pipe 112 is connected to the first pipe; or it can be that Figure 1 , Figure 2 and Figure 5 As shown, the third branch pipe 112 is connected to the power pipeline, etc.; or it may be that the cross pipe only includes the first pipeline, excluding the power pipeline, and in this scheme the third branch pipe 112 is connected to the first pipeline; the above can all achieve the purpose of the present application, and its purpose does not deviate from the design concept of the present invention, and will not be repeated here, and should all fall within the protection scope of the present application.

[0032] The water of the upper pool 700 is continuously supplied to the main pipe 111 from the water inlet, and the drain valve 120 is used to drain water. When the thrust of the water flow in the main pipe 111 pushes the valve flap assembly of the drain valve 120 to move upward and close the drain valve 120, the drain valve 120 will stop draining water, and a severe water hammer effect will occur inside the main pipeline and the pressure will increase rapidly. This pressure not only causes the valve flap assembly of the water delivery valve 130 to move upward and open the water delivery valve 130 (realizing that the water inside the main pipeline will flow into the pressure tank 140 from the water delivery valve 130), but also causes the liquid level in the third branch pipe 112 to rise (realizing that the gas above the liquid level in the third branch pipe 112 is supplied from the second one-way valve 300 to the air pressure driving device 400, and the first one-way valve 200 is cut off in this process); after the water hammer effect ends, not only the drain valve 130 is opened, but also the pressure in the third branch pipe 112 is increased. The valve flap assembly of 120 is reset to open the drain valve 120 again (to enable the drain valve 120 to continue to drain water), the valve flap assembly of the water delivery valve 130 is reset to close the water delivery valve 130, and the liquid level in the third branch pipe 112 is also lowered (to enable the external gas to replenish air from the first one-way valve 200 to the liquid level in the third branch pipe 112, and the second one-way valve 300 is cut off during this process); therefore, when the water hammer pump body 100 is continuously running, the liquid level in the third branch pipe 112 will rise and fall periodically, the first one-way valve 200 will periodically replenish air to the liquid level in the third branch pipe 112, and the second one-way valve 300 will periodically supply air to the air pressure driving device 400, which can not only realize the continuous water lifting of the pressure tank 140, but also realize the continuous operation of the air pressure driving device 400.

[0033] In some examples, such as Figure 1 , Figure 2 and Figure 5 As shown, the water hammer pump system also includes: an air tank 500, the second one-way valve 300 is connected to the air pressure driving device 400 through the air tank 500, the air tank 500 stores the gas supplied by the second one-way valve 300, and supplies this part of the gas to the air pressure driving device 400 when the gas reaches the set pressure F, so that the air pressure driving device 400 is driven by the pressure gas of the set pressure F, so that the operation stability of the air pressure driving device 400 is better.

[0034] In some examples, such as Figure 2 and Figure 5As shown, the water hammer pump system also includes: a second piston 900, which is sealed and arranged in the third branch pipe 112 so as to be movable up and down, and the third interface and the fourth interface are both located above the second piston 900. The liquid level of water in the third branch pipe 112 is located below the second piston 900, and the second piston 900 performs periodic lifting and lowering actions together with the liquid level of water in the third branch pipe 112, so as to prevent the water in the third branch pipe 112 from flowing to the gas tank 500 and the air pressure drive device 400 along the second one-way valve 300. Among them, the second piston 900 has a guide column protruding upward, and the top wall of the third branch pipe 112 is provided with a guide hole, and the guide column is sealed and arranged in the guide hole so as to be movable up and down, so as to realize that the second piston 900 is tilted in the third branch pipe 112.

[0035] In some examples, such as Figure 1 and Figure 2 As shown, the pneumatic drive device 400 includes a pneumatic pump (ie, a pneumatic liquid pump).

[0036] The liquid inlet of the pneumatic pump is connected to the tailwater pool 600, and the water outlet of the pneumatic pump is connected to the upper pool 700. The second one-way valve 300 periodically supplies air to the air tank 500, and the air tank 500 continuously supplies air to the pneumatic pump, so that the pneumatic pump runs continuously, and the pneumatic pump supplies water from the tailwater pool 600 to the upper pool 700. This solution can effectively improve the water pumping volume of the water hammer pump body 100 and the utilization rate of the water in the upper pool 700 under the same hydraulic performance.

[0037] The pneumatic pump may be a pneumatic diaphragm pump; or the pneumatic pump may be a pneumatic plunger pump, etc.; all of the above can achieve the purpose of this application, and their purpose does not deviate from the design concept of the present invention, and will not be repeated here, and should all fall within the protection scope of this application.

[0039] The liquid inlet of the liquid pump is connected to the tailwater pool 600, and the water outlet of the liquid pump is connected to the upper pool 700. The second one-way valve 300 periodically supplies air to the gas tank 500, and the gas tank 500 continuously supplies air to the pneumatic motor, so that the pneumatic motor runs continuously, and the pneumatic motor drives the liquid pump to run continuously, and the liquid pump supplies water from the tailwater pool 600 to the upper pool 700. This solution can effectively improve the water pumping volume of the water hammer pump body 100 and the utilization rate of the water in the upper pool 700 under the same hydraulic performance.

[0040] The pneumatic motor may be a piston motor, or a vane motor, or a gear motor, or a turbine motor, etc. All of the above can achieve the purpose of the present application, and their purpose does not deviate from the design concept of the present invention, and will not be repeated here, and all should fall within the protection scope of the present application.

[0041] Of course, it is also possible that the pneumatic motor is transmission-connected to the generator, the generator, the energy storage device and the control device are electrically connected, the control device and the drive motor are electrically connected, the drive motor is transmission-connected to the liquid pump, and under the control of the control device, the generator supplies power to the energy storage device, the energy storage device stores electrical energy and supplies power to the drive motor, the drive motor drives the liquid pump to operate, and the liquid pump operates to supply water from the tailwater tank 600 to the upper tank 700. This scheme can effectively improve the water pumping volume of the water hammer pump body 100 and the utilization rate of the water in the upper tank 700 under the same hydraulic performance.

[0046] In some embodiments, Figure 6 As shown, the transmission conversion device includes a base 441, an eccentric wheel 442 and a driving rod 443. The rotating shaft of the eccentric wheel 442 is rotatably mounted on the base 441. One end of the driving rod 443 is hingedly connected to the piston assembly, and the other end is hingedly connected to the eccentric shaft of the eccentric wheel 442. Figure 6 As shown, the rotary transmission device includes an inertia wheel 451 and an output wheel 452, and the inertia wheel 451 and the output wheel 452 are both fixed on the rotating shaft of the eccentric wheel 442, and the eccentric wheel 442, the inertia wheel 451 and the output wheel 452 rotate synchronously. Under the rotation inertia of the inertia wheel 451, the output wheel 452 and the eccentric wheel 442 can better realize continuous non-stop rotation, and the piston assembly can better realize continuous reciprocating linear movement. In this scheme, in one movement cycle of the piston assembly, the rotation angle of the eccentric wheel 442, the inertia wheel 451 and the output wheel 452 is 360 degrees. The eccentric wheel 442 includes two, and the two eccentric wheels 442 are connected by an eccentric shaft, and two rotating shafts are set on the opposite sides of the two eccentric wheels.

[0047] In some embodiments, the water hammer pump system further includes: a liquid pump, which is drivingly connected to the output wheel 452, and the output wheel 452 is configured to drive the liquid pump to operate (not shown in the diagram of this solution).

[0048] The liquid inlet of the liquid pump is connected to the tailwater tank 600, and the water outlet of the liquid pump is connected to the upper tank 700. The output wheel 452 drives the liquid pump to rotate continuously, and the liquid pump supplies water from the tailwater tank 600 to the upper tank 700. This solution can effectively improve the water pumping volume of the water hammer pump body 100 and the utilization rate of the water in the upper tank 700 under the same hydraulic performance.

[0049] In other embodiments, Figure 5As shown, the water hammer pump system also includes: an electrically connected generator 910, an energy storage device and a control device, the generator 910 is drivingly connected to the output wheel 452, the output wheel 452 is configured to drive the generator 910 to operate, the energy storage device is configured to store the electric energy generated by the generator 910 and supply power to the drive motor; the drive motor is electrically connected to the control device; the liquid pump 920, the liquid pump 920 is drivingly connected to the drive motor, and the drive motor is configured to drive the liquid pump 920 to operate.

[0050] The output wheel 452 drives the generator 910 to run continuously. Under the control of the control device, the generator 910 supplies power to the energy storage device, the energy storage device stores electrical energy and supplies power to the drive motor, and the drive motor drives the liquid pump 920 to run. The liquid pump 920 runs to supply water from the tailwater tank 600 to the upper tank 700. This solution can effectively improve the water pumping volume of the water hammer pump body 100 and the utilization rate of the water in the upper tank 700 under the same hydraulic performance.

[0051] In summary, according to the technical solution provided by the embodiment of the present invention, when the water hammer pump system is in use, the upper end of the third branch pipe, the third interface and the fourth interface are all located above the liquid level of the water in the upper pool, the water in the upper pool is continuously supplied to the main pipe from the water inlet, the drain valve discharges water, and when the thrust of the water flow in the main pipe pushes the valve flap assembly of the drain valve to operate and close the drain valve, the drain valve will stop draining water, and a severe water hammer effect will occur inside the main pipeline and the pressure will increase rapidly. This pressure not only causes the valve flap assembly of the water delivery valve to operate and open the water delivery valve, so that the water inside the main pipeline flows from the water delivery valve into the pressure tank, but also causes the liquid level in the third branch pipe to rise, so that the gas above the liquid level in the third branch pipe is supplied from the second one-way valve to the air pressure drive device. , during this process, the first one-way valve is cut off; after the water hammer effect ends, not only the valve flap assembly of the drain valve is reset and the drain valve is opened again, so that the drain valve continues to drain water, the valve flap assembly of the water supply valve is reset and the water supply valve is closed, but also the liquid level in the third branch pipe is lowered, so that the external gas is replenished from the first one-way valve to the liquid level above the third branch pipe, and the second one-way valve is cut off in this process; therefore, when the water hammer pump body is continuously running, the liquid level in the third branch pipe will rise and fall periodically, the first one-way valve will periodically replenish air to the liquid level above the third branch pipe, and the second one-way valve will periodically supply air to the air pressure drive device, so that not only the pressure tank can continuously lift water, but also the air pressure drive device can continuously operate.

[0052] Furthermore, the pneumatic drive device directly or indirectly drives the liquid pump to operate, and the liquid pump supplies water from the tailwater tank to the upper tank. This solution can effectively improve the pumping volume of the water hammer pump body and the utilization rate of the water in the upper tank under the same hydraulic performance.
