Description

Technical Field

[0001] This utility model relates to the field of energy conservation and environmental protection technology, and more specifically, to a water hammer pump system. Background Technology

[0002] The water hammer pump body includes components such as a drain valve, a delivery valve, a pressure tank, and main pipelines. Both the drain valve and the delivery valve are check valves. The main pipelines have an inlet, a first interface, and a second interface. The pressure tank has a third interface and a discharge port. The drain valve is installed at the first interface, and the delivery valve connects the second interface and the third interface. The second interface has an air inlet on its wall.

[0003] A water hammer pump is an automatic water pumping machine that utilizes the power of flowing water to generate a water hammer effect through the mechanical action of two check valves (a drain valve and a supply valve), lifting water from a lower level to a higher level. Water hammer pumps do not consume energy sources such as coal, oil, or electricity, making them economical, practical, and offering significant environmental benefits. Specific engineering procedures include:

[0004] Initially, the drain valve is open due to the weight of its valve assembly, while the supply valve is closed. Due to the water level difference, water from the upper tank is supplied to the main pipeline through the power water pipe from the inlet and then discharged into the tailrace tank via the drain valve. When the water flow in the power water pipe accelerates to a velocity exceeding a certain critical value, causing the thrust of the water flow to exceed the weight of the drain valve's valve assembly, the thrust pushes the drain valve's valve assembly to close. The sudden closure of the drain valve causes a severe water hammer effect inside the main pipeline, resulting in a rapid increase in pressure. This causes the supply valve's valve assembly to open, allowing water from the main pipeline to flow into the pressure tank. At this point, the air inside the pressure tank is compressed, increasing the pressure, while the water in the main pipeline decreases, reducing the pressure. This causes the valve disc assembly of the water supply valve to reset, closing the water supply valve again. Conversely, the valve disc assembly of the drain valve resets, reopening the drain valve, and the water hammer pump enters the next working cycle. This cycle repeats, ensuring continuous water output from the pumping station.

[0005] In the previous cycle, water from the main pipeline enters the pressure tank, creating a negative pressure at the second interface of the main pipeline. As a result, outside air is drawn into the main pipeline through the air inlet and flows into the pressure tank along with the water in the main pipeline in the next cycle, replenishing the air dissolved and discharged by the water in the pressure tank.

[0006] Existing water hammer pumps only have the function of lifting water, which is relatively simple. Utility Model Content

[0019] In some exemplary embodiments, the third branch pipe is erected vertically, the third interface is located at the top of the third branch pipe, and the water hammer pump system further includes: an elastic element, one end of which is connected to the base frame and the other end of which is connected to the second transmission element, the elastic element being configured to lift the piston assembly to the maximum speed of downward linear motion.

[0026] The water hammer pump system provided in this embodiment of the utility model continuously supplies water from the upper tank into the main pipe through the inlet. A drain valve discharges water. When the thrust of the water flow in the main pipe pushes the valve disc assembly of the drain valve to close it, the drain valve stops discharging water. A severe water hammer effect occurs inside the main pipe, causing a rapid increase in pressure. This pressure not only causes the valve disc assembly of the delivery valve to open, allowing water from inside the main pipe to flow into the pressure tank, but also causes the piston assembly to move linearly. After the water hammer effect ends, the valve disc assembly of the drain valve resets, reopening the drain valve and allowing it to continue discharging water. The valve disc assembly of the delivery valve resets, closing the delivery valve. Furthermore, the piston assembly moves in the opposite direction and resets. Therefore, during continuous operation of the water hammer pump, the piston assembly periodically reciprocates linearly. The transmission conversion device converts the reciprocating linear movement of the piston assembly into unidirectional rotation of the rotary transmission device. This unidirectional rotation drives the rotor of the power generation device to rotate in one direction, thereby generating electricity.

[0027] Furthermore, the water pump is electrically connected to the power generation device, which supplies power to the water pump. The water pump operates under power to supply water from the tailrace pool to the upper pool. This scheme can effectively improve the pumping capacity of the water hammer pump and the utilization rate of water in the upper pool under the same hydraulic performance.

Detailed Implementation

[0035] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be arbitrarily combined with each other.

[0036] The water hammer pump system provided in this embodiment of the utility model, such as Figures 1 to 3 As shown, it includes: a water hammer pump body 100, which includes a main pipeline, a drain valve 120, a water supply valve 110, and a pressure tank 140. The main pipeline includes a main pipe and a third branch pipe 133 connected to each other. The main pipe has an inlet 134, a first interface 135, and a second interface 136. The third branch pipe 133 has a third interface 137. The drain valve 120 is located at the first interface 135, and the pressure tank 140 and the water supply valve 110 are located at the second interface 136. A piston assembly 200 is connected to the third... Interface 137 is reciprocally and movably sealed and installed on the third branch pipe 133; the generator 300, transmission conversion device 400 and rotation transmission device 500, piston assembly 200, transmission conversion device 400, rotation transmission device 500 and the rotor of generator 300 are sequentially connected in transmission. The transmission conversion device 400 is configured to convert the reciprocating linear movement of piston assembly 200 into unidirectional rotation of rotation transmission device 500. The rotation transmission device 500 is configured to drive the rotor of generator 300 to rotate unidirectionally.

[0037] In this water hammer pump system, water from the upper tank 900 is continuously supplied into the main pipe through the inlet 134. The drain valve 120 discharges water. When the thrust of the water flow in the main pipe pushes the valve disc assembly of the drain valve 120 to close it, the drain valve 120 stops discharging. A severe water hammer effect occurs inside the main pipe, causing a rapid increase in pressure. This pressure not only causes the valve disc assembly of the delivery valve 110 to open (allowing water from the main pipe to flow into the pressure tank 140 from the delivery valve 110), but also causes the piston assembly 200 to move linearly. After the water hammer effect ends, not only the drain valve 120... The valve assembly resets, reopening the drain valve 120 (allowing the drain valve 120 to continue draining water), the valve assembly of the water supply valve 110 resets, closing the water supply valve 110, and the piston assembly 200 also moves in the opposite direction and resets. Therefore, when the water hammer pump body 100 runs continuously, the piston assembly 200 will periodically reciprocate linearly. The transmission conversion device 400 will convert the reciprocating linear movement of the piston assembly 200 into unidirectional rotation of the rotary transmission device 500. During the unidirectional rotation, the rotary transmission device 500 will drive the rotor of the power generation device 300 to rotate unidirectionally, thereby enabling the power generation device 300 to generate electricity. Among them, the third interface 137 is higher than or slightly lower than the water level in the upper pool 900 (under the action of the gravity of the piston assembly 200, the water level inside the third branch pipe 133 will be slightly lower than the water level in the upper pool 900).

[0038] The components of the third branch pipe 133, piston assembly 200, power generation device 300, transmission conversion device 400, and rotational transmission device 500 may be a single set; or the components of the third branch pipe 133, piston assembly 200, power generation device 300, transmission conversion device 400, and rotational transmission device 500 may be multiple sets, which may be two, three, or four sets, etc.; the third branch pipe 133 may be a straight pipe, or it may be a bent pipe including a horizontal section and a vertical section, with the vertical section located on one side of the main pipe and the lower end of the vertical section connected to the main pipe through the horizontal section, etc.; all of the above can achieve the purpose of this application, and their purpose has not departed from the design concept of this utility model, and will not be elaborated here, and should all fall within the protection scope of this application.

[0039] In some examples, such as Figures 1 to 3As shown, the main pipe includes a horizontal pipe, a first branch pipe 131, and a second branch pipe 132. Both the first and second branch pipes 131 and 132 are located above the horizontal pipe and are connected to it at their lower ends. An inlet 134 is located at one end of the horizontal pipe. A first interface 135 is located at the top of the first branch pipe 131, a second interface 136 is located at the top of the second branch pipe 132, and a third branch pipe 133 is also located above the horizontal pipe and is connected to it at its lower end. A third interface 137 is located at the top of the third branch pipe 133. The first, second, and third branch pipes 131, 132, and 133 are all vertically arranged in the vertical direction. The piston assembly 200 reciprocates periodically in the vertical direction, as do the valve disc assembly of the drain valve 120 and the valve disc assembly of the supply valve 110.

[0040] It could be that the third branch pipe 133 is located between the first branch pipe 131 and the second branch pipe 132; or it could be, as... Figures 1 to 3 As shown, the second branch pipe 132 is located between the first branch pipe 131 and the third branch pipe 133; or the first branch pipe 131 is located between the second branch pipe 132 and the third branch pipe 133, etc.; all of the above can achieve the purpose of this application, and their purpose has not departed from the design concept of this utility model, so they will not be described in detail here, and all should fall within the protection scope of this application.

[0041] In some embodiments, such as Figure 3 As shown, the horizontal pipe includes a first pipe 138 and a power pipe 139 that are connected. The axes of the first pipe 138 and the power pipe 139 intersect perpendicularly or obliquely. For example, the power pipe 139 extends obliquely upward from one end adjacent to the first pipe 138 to the end away from the first pipe 138 (i.e., the axes of the first pipe 138 and the power pipe 139 intersect obliquely). The inlet 134 is located at the end of the power pipe 139 away from the first pipe 138. The second branch pipe 132 is located between the first branch pipe 131 and the third branch pipe 133. Both the first branch pipe 131 and the second branch pipe 132 are connected to the first pipe 138. Alternatively, the first branch pipe 131 may be configured as an elbow, and the elbow may be connected to the end of the first pipe 138 away from the power pipe 139. Alternatively, the third branch pipe 133 may be connected to the first pipe 138; or it may be as follows: Figure 3 As shown, the third branch pipe 133 is connected to the power pipe 139 in various ways; for example, Figure 1 and Figure 2 As shown, the horizontal pipe only includes the first pipe 138 and does not include the power pipe 139. In this scheme, the third branch pipe 133 is connected to the first pipe 138. All of the above can achieve the purpose of this application. Their purpose has not deviated from the design concept of this utility model, and will not be repeated here. They should all fall within the protection scope of this application.

[0042] Water from the upper tank 900 is continuously supplied into the main pipe through the inlet 134. The drain valve 120 drains water. When the thrust of the water flow in the main pipe pushes the valve disc assembly of the drain valve 120 upwards, closing the drain valve 120, the drain valve 120 stops draining. A severe water hammer effect occurs inside the main pipe, causing a rapid increase in pressure. This pressure not only causes the valve disc assembly of the water supply valve 110 to move upwards, opening the water supply valve 110 (allowing water from the main pipe to flow into the pressure tank 140 from the water supply valve 110), but also causes the piston assembly 200 to move upwards (driving the transmission conversion device 400). After the water hammer effect ends, the valve disc assembly of the drain valve 120 moves downwards to reset, reopening the drain valve 120 (allowing water to drain again). (Valve 120 continues to discharge water), the valve disc assembly of the water supply valve 110 moves downward to reset and close the water supply valve 110. Simultaneously, the piston assembly 200 (under its own weight and the downward suction force of the water inside the third branch pipe 133) also moves downward to reset (allowing the piston assembly 200 to continue driving the transmission conversion device 400). Therefore, when the water hammer pump body 100 is running continuously, the piston assembly 200 will periodically reciprocate linearly to drive the transmission conversion device 400. The transmission conversion device 400 converts the reciprocating linear movement of the piston assembly 200 into unidirectional rotation of the rotary transmission device 500. During this unidirectional rotation, the rotary transmission device 500 drives the rotor of the power generation device 300 to rotate unidirectionally, enabling the power generation device 300 to generate electricity. Thus, when the water hammer pump body 100 is running continuously, it can not only continuously pump water from the pressure tank 140 but also continuously generate electricity from the power generation device 300.

[0043] In some examples, such as Figures 1 to 3As shown, the water hammer pump system also includes a base frame 610 and a mounting shaft 620. The mounting shaft 620 is rotatably mounted on the base frame 610. The transmission conversion device 400 is fixedly connected to the mounting shaft 620 and is configured to convert the reciprocating linear movement of the piston assembly 200 into the rotational movement of the mounting shaft 620. The rotational transmission device 500 includes a drive wheel 510, which is mounted on the mounting shaft 620. The mounting shaft 620 is configured to drive the drive wheel 510 to rotate in one direction. The drive wheel 510 is configured to drive the rotor of the generator 300 to rotate in one direction (either the rotation direction of the drive wheel 510 is the same as the rotation direction of the rotor of the generator 300; or the rotation direction of the drive wheel 510 is opposite to the rotation direction of the rotor of the generator 300). Alternatively, a ratchet mechanism can be provided between the mounting shaft 620 and the drive wheel 510 (allowing the drive wheel 510 to rotate unidirectionally relative to the mounting shaft 620). The ratchet mechanism is configured to enable the mounting shaft 620 to drive the drive wheel 510 to rotate unidirectionally in the forward direction (or unidirectionally in the reverse direction). Specifically, the mounting shaft 620 can be configured to drive the drive wheel 510 to rotate unidirectionally in the forward direction, thus allowing the drive wheel 510 to rotate unidirectionally relative to the mounting shaft 620; or the mounting shaft 620 can be configured to drive the drive wheel 510 to rotate unidirectionally in the reverse direction, thus allowing the drive wheel 510 to rotate unidirectionally relative to the mounting shaft 620. The ratchet mechanism has advantages such as mature technology, low purchase cost, and long service life.

[0044] When the water hammer pump operates, the transmission conversion device 400 converts the reciprocating linear movement of the piston assembly 200 into the rotational motion of the mounting shaft 620 (the rotation of the mounting shaft 620 can be unidirectional or reciprocating). The following example illustrates this: the mounting shaft 620 drives the drive wheel 510 to rotate unidirectionally, and during this forward rotation, the drive wheel 510 drives the rotor of the generator 300 to rotate forward.

[0045] The transmission conversion device 400 converts the reciprocating linear movement of the piston assembly 200 into the unidirectional forward rotation of the mounting shaft 620 (in this scheme, a ratchet mechanism can be omitted between the mounting shaft 620 and the drive wheel 510). During the unidirectional forward rotation of the mounting shaft 620, the mounting shaft 620 will drive the drive wheel 510 to rotate in the forward direction. The forward rotation of the drive wheel 510 will drive the rotor of the power generation device 300 to rotate in the forward direction, thereby enabling the power generation device 300 to generate electricity. In this design, the piston assembly 200 performs one reciprocating linear movement, and the rotation angle of the mounting shaft 620 is 360 degrees. (If a ratchet mechanism is provided between the mounting shaft 620 and the drive wheel 510, the drive wheel 510 will rotate relative to the mounting shaft 620 under inertia, and the rotation angle of the drive wheel 510 is generally greater than 360 degrees. If no ratchet mechanism is provided between the mounting shaft 620 and the drive wheel 510, and the mounting shaft 620 and the drive wheel 510 are fixedly connected, the rotation angle of the drive wheel 510 is 360 degrees.) This design is not shown in the figure.

[0046] The transmission conversion device 400 converts the reciprocating linear movement of the piston assembly 200 into the reciprocating rotation of the mounting shaft 620 (this scheme requires a ratchet mechanism between the mounting shaft 620 and the drive wheel 510), such as Figures 1 to 3 As shown, during the forward rotation of the mounting shaft 620, the mounting shaft 620 will drive the drive wheel 510 to rotate forward under the action of the ratchet mechanism. The forward rotation of the drive wheel 510 will drive the rotor of the power generation device 300 to rotate forward, thus realizing the power generation device 300 generating electricity. During the reverse rotation of the mounting shaft 620, the drive wheel 510 will continue to rotate forward under the action of inertia (that is, the drive wheel 510 does not rotate backward with the mounting shaft 620), and the rotor of the power generation device 300 will also continue to rotate forward under the drive of the drive wheel 510. In this scheme, the piston assembly 200 performs one reciprocating linear movement, and the rotation angle of the mounting shaft 620 in both the forward and reverse directions is less than 180 degrees.

[0047] In some embodiments, such as Figures 1 to 3As shown, the transmission conversion device 400 includes an inclined first transmission member 410 and an inclined second transmission member 420. The mounting shaft 620 is horizontally arranged above the piston assembly 200. The piston assembly 200 reciprocates linearly in the vertical direction (adjacent reciprocating linear movements can be continuous, i.e., with a zero interval, or they can be intermittent, such as with an interval of 0.2s, 0.5s, or 1 second). The first transmission member 410 has a first hinge portion and a second hinge portion. The second transmission member 420 has a third hinge portion and a mounting portion. The first hinge portion is hinged to the piston assembly 200. The second hinge portion is located obliquely above the first hinge portion and hinged to the third hinge portion. The mounting portion is located obliquely above the third hinge portion and fixedly connected to the mounting shaft 620. In the horizontal direction, the mounting portion and the first hinge portion are located on the same side of the second and third hinge portions. Alternatively, the first transmission member 410 and the second transmission member 420 may be a linkage mechanism; or the first transmission member 410 and the second transmission member 420 may be a cam mechanism, etc.; all of the above can achieve the purpose of this application, and their purpose has not deviated from the design concept of this utility model, so they will not be elaborated here, and all should fall within the protection scope of this application.

[0048] The transmission conversion device 400 converts the reciprocating linear movement of the piston assembly 200 into the reciprocating rotation of the mounting shaft 620, such as... Figures 1 to 3 As shown, then:

[0049] Alternatively, if the piston assembly 200 moves upward in a linear motion, the transmission conversion device 400 drives the mounting shaft 620 to rotate in one direction. The mounting shaft 620, through a ratchet mechanism, drives the drive wheel 510 to rotate in one direction as well. The rotor of the generator 300 rotates in one direction along with the drive wheel 510. During this process, the rotation angle of the mounting shaft 620 is less than 180 degrees. If the piston assembly 200 moves downward in a linear motion, the transmission conversion device 400 drives the mounting shaft 620 to rotate in one direction in the opposite direction. The drive wheel 510 continues to rotate in one direction due to inertia. The rotor of the generator 300 rotates in one direction along with the drive wheel 510. During this process, the rotation angle of the mounting shaft 620 is less than 180 degrees. In this scheme, the drive wheel 510 can be mounted on the mounting shaft 620 in a unidirectional forward rotation.

[0050] Alternatively, based on the downward linear movement of the piston assembly 200, the transmission conversion device 400 drives the mounting shaft 620 to rotate in one direction in the opposite direction. The mounting shaft 620 drives the drive wheel 510 to rotate in one direction in the opposite direction via a ratchet mechanism. The rotor of the generator 300 rotates in one direction along with the drive wheel 510 under its drive. During this process, the rotation angle of the mounting shaft 620 is less than 180 degrees. Based on the upward linear movement of the piston assembly 200, the transmission conversion device 400 drives the mounting shaft 620 to rotate in one direction in the forward direction. The drive wheel 510 continues to rotate in one direction in the opposite direction under the action of inertia. The rotor of the generator 300 rotates in one direction along with the drive wheel 510 under its drive. During this process, the rotation angle of the mounting shaft 620 is less than 180 degrees. In this scheme, the drive wheel 510 can be mounted on the mounting shaft 620 in a unidirectionally reverse rotational manner.

[0051] The rotation angle of the mounting shaft 620 in one unidirectional rotation can be set to 30 degrees; or it can be set to 60 degrees; or it can be set to 90 degrees; or it can be set to 120 degrees; or it can be set to 150 degrees, etc.

[0052] All of the above can achieve the purpose of this application, and their purpose has not deviated from the design concept of this utility model. They will not be repeated here, and should all fall within the protection scope of this application.

[0053] The transmission conversion device 400 converts the reciprocating linear movement of the piston assembly 200 into the unidirectional forward rotation of the mounting shaft 620 (not shown in this schematic diagram). Therefore:

[0054] The mounting shaft 620 is horizontally arranged directly above the piston assembly 200. The second hinge and the third hinge are hinged together (not shown in this schematic diagram). When the piston assembly 200 is in the initial state (the piston assembly 200 is in the lower limit displacement position), the first transmission member 410 and the second transmission member 420 are both vertically arranged in the vertical direction, and the first transmission member 410 is directly below the second transmission member 420. The vertical dimension of the first transmission member 410 minus the vertical dimension of the second transmission member 420 equals the absolute value of the maximum displacement of the piston assembly 200. The absolute value of the maximum displacement of the piston assembly 200 equals the value of the maximum upward stroke of the piston assembly 200 equals the value of the maximum downward stroke of the piston assembly 200. When the piston assembly 200 moves upward in a linear motion, the transmission conversion device 400 drives the mounting shaft 620 to rotate in one direction. The mounting shaft 620 drives the drive wheel 510 to rotate in one direction, which in turn drives the rotor of the generator 300 to rotate in one direction. During this process, the rotation angle of the mounting shaft 620 is 180 degrees. When the piston assembly 200 moves downward in a linear motion, the transmission conversion device 400 drives the mounting shaft 620 to continue rotating in one direction. The mounting shaft 620 drives the drive wheel 510 to continue rotating in one direction, which in turn drives the rotor of the generator 300 to rotate in one direction. During this process, the rotation angle of the mounting shaft 620 is 180 degrees. That is, the piston assembly 200 performs one up-and-down reciprocating movement. The mounting shaft 620 drives the drive wheel 510 to complete a unidirectional rotation of 360 degrees. (If a ratchet mechanism is provided between the mounting shaft 620 and the drive wheel 510, the drive wheel 510 will rotate relative to the mounting shaft 620 under inertia. At this time, the rotation angle of the mounting shaft 620 is 360 degrees, and the rotation angle of the drive wheel 510 is generally greater than 360 degrees. If no ratchet mechanism is provided between the mounting shaft 620 and the drive wheel 510, and the mounting shaft 620 and the drive wheel 510 are fixedly connected, then the mounting shaft 620 and the drive wheel 510 rotate synchronously and both rotate at 360 degrees.) This solution can also achieve the purpose of this application. Its purpose has not departed from the design concept of this utility model, and will not be elaborated here. It should also fall within the protection scope of this application.

[0055] In some embodiments, such as Figures 1 to 3 As shown, the rotational transmission device 500 also includes a driven wheel 520, which is mounted on the rotor of the power generation device 300 and is connected to the driving wheel 510 in a transmission manner. Based on the rotation of the driving wheel 510, the driving wheel 510 drives the driven wheel 520 to rotate, and the driven wheel 520 drives the rotor of the power generation device 300 to rotate.

[0056] It could be that the driving gear 510 is the driving gear and the driven gear 520 is the driven gear, with the teeth of the driving gear meshing with the teeth of the driven gear for transmission. If the driving gear rotates in the forward direction, the driven gear rotates in the reverse direction, and the rotor of the generator 300 rotates in the reverse direction; or it could be, as... Figures 1 to 3 As shown, the driving pulley 510 is a driving pulley, and the driven pulley 520 is a driven pulley. The driving pulley and the driven pulley are connected by a conveyor belt. When the driving pulley rotates in the forward direction, the driven pulley rotates in the forward direction, and the rotor of the power generation device 300 rotates in the forward direction. Alternatively, the driving pulley 510 can be a driving sprocket, and the driven pulley 520 can be a driven sprocket. The driving sprocket and the driven sprocket are connected by a conveyor chain. When the driving sprocket rotates in the forward direction, the driven sprocket rotates in the forward direction, and the rotor of the power generation device 300 rotates in the forward direction. All of the above can achieve the purpose of this application, and their purpose has not departed from the design concept of this utility model. They will not be elaborated here, and all should fall within the protection scope of this application.

[0057] In some embodiments, such as Figure 1 As shown, the water hammer pump body 100 also includes a cover 700, which is installed on the third interface 137 and has a through hole. The piston assembly 200 includes a piston and a piston rod connected to each other. The piston is located inside the third branch pipe 133 and is sealed to the inner circumferential surface of the third branch pipe 133. The piston rod passes upward through the through hole and is hinged to the first hinge part. The cover 700 prevents the piston from coming out of the third branch pipe 133 from the third interface 137.

[0058] In some embodiments, such as Figure 1 As shown, the water hammer pump system also includes: an elastic element 800 (such as a helical spring), the upper end of which is connected to the base frame 610 and the lower end of which is connected to the second transmission element 420. The elastic element 800 is set to lift the piston assembly 200 to move downward at the maximum speed, so that the piston assembly 200 has a larger stroke and the power generation efficiency of the power generation device 300 is higher.

[0059] In other examples, the transmission conversion device 400 includes a rack, the rotational transmission device 500 includes a gear, the rack is erected and fixed on the piston assembly 200, and the gear (such as by a ratchet mechanism) is unidirectionally rotatable on the rotor of the power generation device 300 and meshes with the rack (not shown in this embodiment).

[0060] Alternatively, the piston assembly 200 can move upwards along with the rack, causing the rack to drive the gear to rotate in the forward direction. The gear, through a ratchet mechanism, drives the rotor of the power generation device 300 to rotate in the forward direction. Conversely, if the piston assembly 200 moves downwards along with the rack, the rack drives the gear to rotate in the reverse direction. The gear, unable to drive the rotor of the power generation device 300 in the reverse direction through the ratchet mechanism, will continue to rotate in the forward direction due to inertia. In this way, the water hammer pump body 100 operates continuously, enabling the power generation device 300 to generate electricity continuously.

[0061] Alternatively, the piston assembly 200 can move downwards along with the rack, causing the rack to drive the gear to rotate in the opposite direction. The gear, through a ratchet mechanism, drives the rotor of the power generation device 300 to rotate in the opposite direction. The piston assembly 200 can also move upwards along with the rack, causing the rack to drive the gear to rotate in the forward direction. Since the gear cannot drive the rotor of the power generation device 300 to rotate in the forward direction through the ratchet mechanism, the rotor of the power generation device 300 will continue to rotate in the opposite direction due to inertia. In this way, the water hammer pump body 100 operates continuously, enabling the power generation device 300 to generate electricity continuously.

[0062] All of the above can achieve the purpose of this application, and their purpose has not deviated from the design concept of this utility model. They will not be repeated here, and should all fall within the protection scope of this application.

[0063] In some other examples, the transmission conversion device 400 includes a rack and a drive gear, and the rotational transmission device 500 includes a drive wheel 510 and a driven wheel 520. The driven wheel 520 is mounted on the rotor of the power generation device 300. The drive gear (e.g., via a ratchet mechanism) is unidirectionally rotatable on the mounting shaft 620 of the base frame 610. The drive wheel 510 is fixedly mounted on the mounting shaft 620 of the base frame 610 and is connected to the driven wheel 520 in a transmission manner. The rack is erected and fixed on the piston assembly 200 and meshes with the drive gear (not shown in this embodiment). This can also achieve the purpose of this application. Its purpose has not departed from the design concept of this utility model, and will not be elaborated here. It should also fall within the protection scope of this application.

[0064] In some other examples, the piston rod has a guide groove on its side (the guide groove includes a first vertical section at the top, an inclined section in the middle, and a second vertical section at the bottom). The eccentric wheel is fixed on the mounting shaft 620, and the eccentric shaft on the eccentric wheel is in transmission engagement with the guide groove. Each time the piston assembly 200 drives the guide groove to move up and down, the guide groove drives the eccentric shaft to rotate the eccentric wheel 360 degrees. The eccentric wheel drives the mounting shaft 620 to rotate 360 ​​degrees. The mounting shaft 620 drives the rotor of the power generation device 300 to rotate through the rotation transmission device 500 (for technical solutions with a ratchet mechanism between the mounting shaft 620 and the rotation transmission device 500, the rotation angle between the rotation transmission device 500 and the rotor of the power generation device 300 is generally greater than 360 degrees due to the inertia of the rotation transmission device 500), thus enabling the power generation device 300 to generate electricity. The transmission conversion device 400 includes the guide groove, the eccentric wheel, and the eccentric shaft on the eccentric wheel (not shown in this diagram). This solution can also achieve the purpose of this application. Its purpose has not deviated from the design concept of this utility model, so it will not be repeated here. It should also fall within the protection scope of this application.

[0065] In some examples, the water hammer pump system also includes: a water pump (not shown in the figure), and the water pump, a power generation unit 300, an energy storage unit, and a control unit electrically connected. Under the control of the control unit, the power generation unit 300 is configured to supply power to the energy storage unit, which is configured to store electrical energy and supply power to the water pump. The energized water pump operates to supply water from the tailrace pool to the upper pool 900. This scheme can effectively improve the pumping capacity of the water hammer pump body 100 and the utilization rate of water in the upper pool 900 under the same hydraulic performance.

[0066] It is possible that the forward direction in this application is clockwise and the reverse direction is counterclockwise; or it is possible that the forward direction in this application is counterclockwise and the reverse direction is clockwise; both of the above can achieve the purpose of this application, and their purpose has not deviated from the design concept of this utility model, so they will not be elaborated here, and all should fall within the protection scope of this application.

[0067] In summary, the water hammer pump system provided by this utility model embodiment continuously supplies water from the upper tank into the main pipe through the inlet. The drain valve discharges water. When the thrust of the water flow within the main pipe pushes the valve disc assembly of the drain valve to close it, the drain valve stops discharging water. A severe water hammer effect occurs inside the main pipe, causing a rapid increase in pressure. This pressure not only causes the valve disc assembly of the delivery valve to open, allowing water from inside the main pipe to flow into the pressure tank from the delivery valve, but also causes the piston assembly to move linearly. Once the water hammer effect ends... Subsequently, not only does the valve disc assembly of the drain valve reset and reopen the drain valve, allowing it to continue draining water, but the valve disc assembly of the delivery valve also resets and closes the delivery valve. Furthermore, the piston assembly also moves in the opposite direction and resets. Therefore, when the water hammer pump is running continuously, the piston assembly will periodically reciprocate linearly. The transmission conversion device will convert the reciprocating linear movement of the piston assembly into unidirectional rotation of the rotary transmission device. During the unidirectional rotation, the rotary transmission device will drive the rotor of the power generation device to rotate in one direction, thereby enabling the power generation device to generate electricity.

[0068] Furthermore, the water pump is electrically connected to the power generation device, which supplies power to the water pump. The water pump operates under power to supply water from the tailrace pool to the upper pool. This scheme can effectively improve the pumping capacity of the water hammer pump and the utilization rate of water in the upper pool under the same hydraulic performance.
