Abstract
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

[0012] In some exemplary embodiments, the first interface is oriented upwards, and the transmission conversion device is configured to convert the reciprocating linear movement of the valve assembly into unidirectional forward rotation of the mounting shaft.

[0019] In some exemplary embodiments, the first interface is arranged facing upwards, 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.

Detailed Implementation
[0030] 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.
[0031] The water hammer pump system provided in this embodiment of the utility model, such as Figure 1 and Figure 2As shown, it includes: a water hammer pump body, which includes a main pipeline 110, a drain valve 120, and a water supply valve 130. The main pipeline 110 has an inlet 111, a first interface 112, and a second interface 113. The drain valve 120 is located at the first interface 112, and the water supply valve 130 is located at the second interface 113. A power generation device 200 (which may be a generator), a transmission conversion device 300, and a rotation transmission device 400 are also included. The valve disc assembly 140 of the drain valve 120, the transmission conversion device 300, the rotation transmission device 400, and the rotor of the power generation device 200 are sequentially connected. The transmission conversion device 300 is configured to convert the reciprocating linear movement of the valve disc assembly 140 into the unidirectional rotation of the rotation transmission device 400. The rotation transmission device 400 is configured to drive the rotor of the power generation device 200 to rotate unidirectionally.
[0032] In this water hammer pump system, water from the upper pool is continuously supplied into the main pipeline 110 through the inlet 111. When the water hammer pump is running, the valve assembly 140 moves in a reciprocating linear motion continuously or intermittently. During the reciprocating linear motion of the valve assembly 140, the transmission conversion device 300 converts the reciprocating linear motion of the valve assembly 140 into the unidirectional rotation of the rotary transmission device 400. During the unidirectional rotation, the rotary transmission device 400 drives the rotor of the power generation device 200 to rotate in a unidirectional direction, thereby enabling the power generation device 200 to generate electricity.
[0033] Among them, such as Figure 2 As shown, the main pipeline 110 includes a horizontal pipe 114, a first branch pipe 115, and a second branch pipe 116. The first branch pipe 115 and the second branch pipe 116 are located above the horizontal pipe 114 and connected to it at their lower ends. A first interface 112 is located at the upper end of the first branch pipe 115, and a second interface 113 is located at the upper end of the second branch pipe 116. The water inlet is located at one end of the horizontal pipe 114. In this application, the first branch pipe 115 is an elbow, which is connected to the other end of the horizontal pipe 114.
[0034] Furthermore, such as Figure 1 and Figure 2 As shown, the water hammer pump body also includes a pressure tank 600, which is located at the second interface 113. The valve disc assembly 140 of the drain valve 120 and the valve disc assembly of the water supply valve 130 both reciprocate periodically in the up-down direction. When the valve disc assembly of the water supply valve 130 moves upward to open the water supply valve 130, water in the main pipeline 110 flows into the pressure tank through the water supply valve 130. Then, under the pressure difference between the upper and lower sides and the action of gravity, the valve disc assembly of the water supply valve 130 moves downward (resets) to close the water supply valve 130. In this way, the water hammer pump body operates continuously, and the pressure tank 600 continuously pumps water from its outlet 610.
[0035] In some examples, such as Figure 1 and Figure 2As shown, the water hammer pump system also includes a base frame 510 and a mounting shaft 520. The mounting shaft 520 is rotatably mounted on the base frame 510. The transmission conversion device 300 is fixedly connected to the mounting shaft 520 and is configured to convert the reciprocating linear movement of the valve disc assembly 140 into the rotational movement of the mounting shaft 520. The rotational transmission device 400 includes a drive wheel 410, which is mounted on the mounting shaft 520. The mounting shaft 520 is configured to drive the drive wheel 410 to rotate in one direction. The drive wheel 410 is configured to drive the rotor of the generator 200 to rotate in one direction (either the rotation direction of the drive wheel 410 is the same as the rotation direction of the rotor of the generator 200; or the rotation direction of the drive wheel 410 is opposite to the rotation direction of the rotor of the generator 200). Alternatively, a ratchet mechanism can be provided between the mounting shaft 520 and the drive wheel 410 (allowing the drive wheel 410 to rotate unidirectionally relative to the mounting shaft 520). The ratchet mechanism is configured to enable the mounting shaft 520 to drive the drive wheel 410 to rotate unidirectionally in the forward direction (or unidirectionally in the reverse direction). Alternatively, the mounting shaft 620 can be configured to drive the drive wheel 510 to rotate unidirectionally in the forward direction, 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, 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.
[0036] When the water hammer pump is running, the transmission conversion device 300 converts the reciprocating linear movement of the valve disc assembly 140 into the rotational movement of the mounting shaft 520 (the rotation of the mounting shaft 520 can be unidirectional or reciprocating). Taking the example of the mounting shaft 520 driving the drive wheel 410 to rotate unidirectionally in the forward direction, and the drive wheel 410 driving the rotor of the generator 200 to rotate in the forward direction during this rotation, the following explanation will be provided:
[0037] The transmission conversion device 300 converts the reciprocating linear movement of the valve assembly 140 into the unidirectional forward rotation of the mounting shaft 520 (in this scheme, a ratchet mechanism can be omitted between the mounting shaft 520 and the drive wheel 410). During the unidirectional forward rotation of the mounting shaft 520, the mounting shaft 520 will drive the drive wheel 410 to rotate in the forward direction under the action of the ratchet mechanism. The forward rotation of the drive wheel 410 will drive the rotor of the power generation device 200 to rotate in the forward direction, thereby enabling the power generation device 200 to generate electricity. In this scheme, the valve assembly 140 performs one reciprocating linear movement, and the rotation angle of the mounting shaft 520 is 360 degrees (if a ratchet mechanism is provided between the mounting shaft 520 and the drive wheel 410, the drive wheel 410 will rotate relative to the mounting shaft 520 under the action of inertia, and the rotation angle of the drive wheel 410 is generally greater than 360 degrees; if no ratchet mechanism is provided between the mounting shaft 520 and the drive wheel 410, and the mounting shaft 520 and the drive wheel 410 are fixedly connected, then the rotation angle of the drive wheel 410 is 360 degrees).
[0038] The transmission conversion device 300 converts the reciprocating linear movement of the valve disc assembly 140 into the reciprocating rotation of the mounting shaft 520 (a ratchet mechanism is required between the mounting shaft 520 and the drive wheel 410 in this scheme). Therefore: during the forward rotation of the mounting shaft 520, the mounting shaft 520 will drive the drive wheel 410 to rotate forward under the action of the ratchet mechanism. The forward rotation of the drive wheel 410 will drive the rotor of the power generation device 200 to rotate forward, thus generating electricity. During the reverse rotation of the mounting shaft 520, the drive wheel 410 continues to rotate forward under inertia (i.e., the drive wheel 410 does not rotate backward with the mounting shaft 520), and the rotor of the power generation device 200 will also continue to rotate forward under the drive of the drive wheel 410. In this scheme, the rotation angle of the mounting shaft 520 during one reciprocating linear movement of the valve disc assembly 140 is less than 180 degrees, and the rotation angle of the mounting shaft 520 during reverse rotation is also less than 180 degrees.
[0039] In some embodiments, such as Figure 1 and Figure 2As shown, the transmission conversion device 300 includes a first transmission member 310 and a second transmission member 320 arranged at an angle. The mounting shaft 520 is horizontally arranged above the valve disc assembly 140. The valve disc assembly 140 reciprocates linearly in the up-down direction (two adjacent reciprocating linear movements can be continuous, i.e., the interval is 0, or two adjacent reciprocating linear movements can be spaced out, such as the interval is 0.2s, 0.5s, or 1 second). The first transmission member 310 has a first hinge portion and a second hinge portion. The second transmission member 320 has a third hinge portion and a mounting portion 321. The first hinge portion is hinged to the valve disc assembly 140. The second hinge portion is located above the first hinge portion and is hinged to the third hinge portion. The mounting portion 321 is located above the third hinge portion and is fixedly connected to the mounting shaft 520. In the horizontal direction, the mounting portion 321 and the first hinge portion are located on the same side of the second and third hinge portions. Alternatively, the first transmission member 310 and the second transmission member 320 may be a linkage mechanism; or the first transmission member 310 and the second transmission member 320 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.
[0040] The transmission conversion device 300 converts the reciprocating linear movement of the valve disc assembly 140 into the reciprocating rotation of the mounting shaft 520, then:
[0041] Alternatively, if the valve assembly 140 moves upward in a straight line, the transmission conversion device 300 drives the mounting shaft 520 to rotate in one direction. The mounting shaft 520 then drives the drive wheel 410 to rotate in one direction via a ratchet mechanism. The drive wheel 410 then drives the rotor of the generator 200 to rotate. In this process, the rotation angle of the mounting shaft 520 is less than 180 degrees. Alternatively, if the valve assembly 140 moves downward in a straight line, the transmission conversion device 300 drives the mounting shaft 520 to rotate in one direction in the opposite direction. The mounting shaft 520 cannot drive the drive wheel 410 to rotate in the opposite direction. The drive wheel 410 will continue to rotate in one direction due to inertia, and the rotor of the generator 200 will continue to rotate under the drive of the drive wheel 410. In this process, the rotation angle of the mounting shaft 520 is less than 180 degrees. In this configuration, the drive wheel 410 can be mounted on the mounting shaft 520 in a unidirectional forward rotation.
[0042] Alternatively, based on the downward linear movement of the valve assembly 140, the transmission conversion device 300 drives the mounting shaft 520 to rotate in one direction in the reverse direction. The mounting shaft 520 drives the drive wheel 410 to rotate in one direction in the reverse direction via a ratchet mechanism. The drive wheel 410 drives the rotor of the generator 200 to rotate. In this process, the rotation angle of the mounting shaft 520 is less than 180 degrees. Based on the upward linear movement of the valve assembly 140, the transmission conversion device 300 drives the mounting shaft 520 to rotate in one direction in the forward direction. The mounting shaft 520 cannot drive the drive wheel 410 to rotate in one direction in the forward direction. Under the action of inertia, the drive wheel 410 will continue to rotate in one direction in the reverse direction. The rotor of the generator 200 will continue to rotate under the drive of the drive wheel 410. In this process, the rotation angle of the mounting shaft 520 is less than 180 degrees. In this scheme, the drive wheel 410 can be mounted on the mounting shaft 520 in one direction in the reverse direction.
[0043] The rotation angle of the mounting shaft 520 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.
[0044] 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.
[0045] The transmission conversion device 300 converts the reciprocating linear movement of the valve disc assembly 140 into unidirectional forward rotation of the mounting shaft 520. Therefore:
[0046] The mounting shaft 520 is horizontally arranged directly above the valve disc assembly 140. The second hinge part and the third hinge part are hinged together (not shown in this schematic diagram). When the valve disc assembly 140 is in the initial state, the first transmission member 310 and the second transmission member 320 are both erected in the vertical direction, and the first transmission member 310 is located directly below the second transmission member 320. The vertical dimension of the first transmission member 310 minus the vertical dimension of the second transmission member equals the absolute value of the maximum displacement of the valve disc assembly 140. The absolute value of the maximum displacement of the valve disc assembly 140 equals the value of the maximum upward stroke of the valve disc assembly equals the value of the maximum downward stroke of the valve disc assembly. When the valve disc assembly 140 moves upward in a linear motion, the transmission conversion device 300 drives the mounting shaft 520 to rotate in one direction in a positive direction. The mounting shaft 520 drives the drive wheel 410 to rotate in one direction in a positive direction, which in turn drives the rotor of the generator 200 to rotate. During this process, the rotation angle of the mounting shaft 520 is 180 degrees. When the valve disc assembly 140 moves downward in a linear motion, the transmission conversion device 300 drives the mounting shaft 520 to continue rotating in one direction in a positive direction. The mounting shaft 520 drives the drive wheel 410 to continue rotating in one direction in a positive direction, which in turn drives the rotor of the generator 200 to rotate. During this process, the rotation angle of the mounting shaft 520 is 180 degrees. That is, the valve disc assembly 140 performs one up-and-down reciprocating movement. The mounting shaft 520 drives the drive wheel 410 to complete a unidirectional rotation of 360 degrees. (If a ratchet mechanism is provided between the mounting shaft 520 and the drive wheel 410, the drive wheel 410 will rotate relative to the mounting shaft 520 under inertia. The rotation angle of the mounting shaft 520 is 360 degrees, and the rotation angle of the drive wheel 410 is generally greater than 360 degrees. If no ratchet mechanism is provided between the mounting shaft 520 and the drive wheel 410, and the mounting shaft 520 and the drive wheel 410 are fixedly connected, the mounting shaft 520 and the drive wheel 410 will rotate synchronously with a rotation angle of 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.
[0047] In some embodiments, such as Figure 1 and Figure 2 As shown, the rotational transmission device 400 also includes a driven wheel 420, which is mounted on the rotor of the power generation device 200 and is connected to the driving wheel 410 in a transmission manner. Based on the rotation of the driving wheel 410, the driving wheel 410 drives the driven wheel 420 to rotate, and the driven wheel 420 drives the rotor of the power generation device 200 to rotate.
[0048] It could be that the driving gear 410 is the driving gear and the driven gear 420 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 200 rotates in the reverse direction; or it could be, as... Figure 1 and Figure 2 As shown, the driving pulley 410 is a driving pulley, and the driven pulley 420 is a driven pulley. The driving pulley and the driven pulley are connected by a transmission 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 200 rotates in the forward direction. Alternatively, the driving pulley 410 can be a driving sprocket, and the driven pulley 420 can be a driven sprocket. The driving sprocket and the driven sprocket are connected by a transmission 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 200 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.
[0049] In some embodiments, such as Figure 1 and Figure 2 As shown, a connector 141 (such as a connecting rod) protrudes from the top of the valve disc assembly 140, and the first hinge portion is hinged to the connector 141. The valve disc assembly includes a valve disc and a valve stem, with the valve disc mounted on the valve stem. For the valve disc assembly 140 of the drain valve 120, the valve disc is located at the lower part of the valve stem, and the connector 141 is located at the upper part of the valve stem; for the valve disc assembly of the supply valve 130, the valve disc is located at the upper part of the valve stem.
[0050] In some embodiments, such as Figure 1 and Figure 2 As shown, the water hammer pump system also includes: an elastic element 530 (such as a helical spring). The upper end of the elastic element 530 is connected to the base frame 510, and the lower end is connected to the second transmission element 320. The elastic element 530 is configured to extend the action time of the valve disc assembly 140 moving upward in a linear motion and shorten the action time of the valve disc assembly 140 moving downward in a linear motion, so as to quickly reset the valve disc assembly 140. The shorter the reset time of the valve disc assembly 140, the greater the water hammer effect formed by the water hammer pump body (the greater the better).
[0051] In other examples, the transmission conversion device 300 includes a rack, and the rotational transmission device 400 includes a gear. The rack is erected and fixed on the valve assembly 140, and the gear (e.g., via a ratchet mechanism) is unidirectionally rotatable on the rotor of the generator 200 and meshes with the rack.
[0052] Alternatively, the valve assembly 140 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 200 to rotate in the forward direction. Conversely, the valve assembly 140 can move downwards along with the rack, causing the rack to drive the gear to rotate in the reverse direction. The gear, unable to drive the rotor of the power generation device 200 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 operates continuously, enabling the power generation device 200 to generate electricity continuously.
[0053] Alternatively, the valve assembly 140 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 200 to rotate in the opposite direction. The valve assembly 140 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 200 to rotate in the forward direction through the ratchet mechanism, the rotor of the power generation device 200 will continue to rotate in the opposite direction due to inertia. In this way, the water hammer pump operates continuously, enabling the power generation device 200 to generate electricity continuously.
[0054] 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.
[0055] In some other examples, the transmission conversion device 300 includes a rack and a drive gear, and the rotational transmission device 400 includes a drive wheel 410 and a driven wheel 420. The driven wheel 420 is mounted on the rotor of the power generation device 200. The drive gear (e.g., via a ratchet mechanism) is unidirectionally rotatable on the mounting shaft 520 of the base frame 510. The drive wheel 410 is fixedly mounted on the mounting shaft 520 of the base frame 510 and is connected to the driven wheel in a transmission manner. The rack is erected and fixed on the valve assembly 140 and meshes with the drive gear. 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.
[0056] In some examples, the side of the connector 141 (such as a connecting plate) is provided with a guide groove (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 520, and the eccentric shaft on the eccentric wheel is in transmission engagement with the guide groove. Each time the valve disc assembly 140 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 520 to rotate 360 degrees together. The mounting shaft 520 drives the rotor of the power generation device 200 to rotate through the rotation transmission device 400 (for technical solutions where a ratchet mechanism is provided between the mounting shaft 520 and the rotation transmission device 400, the rotation angle between the rotation transmission device 400 and the rotor of the power generation device 200 is generally greater than 360 degrees under the inertia of the rotation transmission device 400), thus enabling the power generation device 200 to generate electricity. The transmission conversion device 300 includes the guide groove, the eccentric wheel, and the eccentric shaft on the eccentric wheel. 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.
[0057] 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 200, an energy storage unit, and a control unit electrically connected. Under the control of the control unit, the power generation unit 200 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. 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.
[0058] 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.
[0059] In summary, the water hammer pump system provided by this utility model embodiment continuously supplies water from the upper pool into the main pipeline through the inlet. When the water hammer pump body is running, the valve disc assembly continuously or intermittently reciprocates linearly. During the reciprocating linear movement of the valve disc assembly, the transmission conversion device converts the reciprocating linear movement of the valve disc assembly into unidirectional rotation of the rotary transmission device. During the unidirectional rotation of the rotary transmission device, the rotor of the power generation device is driven to rotate unidirectionally, thereby enabling the power generation device to generate electricity.
[0060] 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.
