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.

[0005] Existing water hammer pumps only have a water lifting function, and their functions are relatively simple. Summary of the invention

DETAILED DESCRIPTION

[0027] 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.

[0028] The water hammer pump system provided by the embodiment of the present invention is as follows: Figure 1 and Figure 2As shown, it includes: a water hammer pump body, the water hammer pump body includes a main pipeline 110, a drain valve 120 and a water delivery valve 130, the main pipeline 110 has a water inlet 111, a first interface 112 and a second interface 113, the drain valve 120 is arranged at the first interface 112, and the water delivery valve 130 is arranged at the second interface 113; a power generation device 200 (which can be a generator), a transmission conversion device 300 and a rotation transmission device 400, the valve flap 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 in transmission, the transmission conversion device 300 is configured to convert the reciprocating linear movement of the valve flap assembly 140 into a unidirectional rotation of the rotation transmission device 400, and the rotation transmission device 400 is configured to drive the rotor of the power generation device 200 to rotate unidirectionally.

[0029] In the water hammer pump system, water from the upper pool is continuously supplied to the main pipeline 110 from the water inlet 111. When the water hammer pump body is running, the valve flap assembly 140 continuously or intermittently performs reciprocating linear movement. During the reciprocating linear movement of the valve flap assembly 140, the transmission conversion device 300 converts the reciprocating linear movement of the valve flap assembly 140 into a unidirectional rotation of the rotating transmission device 400. During the unidirectional rotation, the rotating transmission device 400 drives the rotor of the power generation device 200 to rotate unidirectionally, thereby enabling the power generation device 200 to generate electricity.

[0030] Among them, Figure 2 As shown, the main pipeline 110 has a transverse 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 on the upper side of the transverse pipe 114 and are connected to the transverse pipe 114 at their lower ends. The first interface 112 is located at the upper end of the first branch pipe 115, the second interface 113 is located at the upper end of the second branch pipe 116, and the water inlet is located at one end of the transverse pipe 114. The first branch pipe 115 of the present application is an elbow, which is connected to the other end of the transverse pipe 114.

[0031] Furthermore, if Figure 1 and Figure 2 As shown, the water hammer pump body further includes a pressure tank 600, which is arranged at the second interface 113. The valve flap assembly 140 of the drain valve 120 and the valve flap assembly of the water delivery valve 130 both perform periodic reciprocating movements in the up-down direction. When the valve flap assembly of the water delivery valve 130 moves upward to open the water delivery valve 130, the water in the main pipeline 110 flows into the pressure tank through the water delivery valve 130, and then the valve flap assembly of the water delivery valve 130 moves downward (resets) under the pressure difference between the upper and lower sides and the action of gravity to close the water delivery valve 130, so that the water hammer pump body continuously operates, and the pressure tank 600 continuously pumps water from the water pumping port 610 of the pressure tank 600.

[0032] 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 flap assembly 140 into the rotational movement of the mounting shaft 520; the rotation transmission device 400 includes: a driving wheel 410, the driving wheel 410 is mounted on the mounting shaft 520, the mounting shaft 520 is configured to be able to drive the driving wheel 410 to rotate unidirectionally, and the driving wheel 410 is configured to drive the rotor of the power generation device 200 to rotate unidirectionally (the rotation direction of the driving wheel 410 is the same as the rotation direction of the rotor of the power generation device 200; or the rotation direction of the driving wheel 410 is opposite to the rotation direction of the rotor of the power generation device 200). It can be that a ratchet mechanism is provided between the installation shaft 520 and the driving wheel 410 (so that the driving wheel 410 can rotate unidirectionally relative to the installation shaft 520), and the ratchet mechanism is configured to enable the installation shaft 520 to drive the driving wheel 410 to rotate unidirectionally (or to rotate unidirectionally). It can be that the installation shaft 620 is configured to drive the driving wheel 510 to rotate unidirectionally, so that the driving wheel 510 can rotate unidirectionally relative to the installation shaft 620; or it can be that the installation shaft 620 is configured to drive the driving wheel 510 to rotate unidirectionally, so that the driving wheel 510 can rotate unidirectionally relative to the installation shaft 620. The ratchet mechanism has the advantages of mature technology, low purchase cost, and long service life.

[0033] 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 installation shaft 520 (the rotation of the installation shaft 520 can be a unidirectional rotation of the installation shaft 520, or a reciprocating rotation of the installation shaft 520). Take the installation shaft 520 driving the driving wheel 410 to rotate forward in a unidirectional manner, and the driving wheel 410 drives the rotor of the power generation device 200 to rotate forward during the forward rotation as an example for explanation: The transmission conversion device 300 converts the reciprocating linear movement of the valve flap assembly 140 into a unidirectional positive rotation of the mounting shaft 520 (in this solution, a ratchet mechanism may not be provided between the mounting shaft 520 and the driving wheel 410). Then: during the unidirectional positive rotation of the mounting shaft 520, the mounting shaft 520 will drive the driving wheel 410 to rotate forward under the action of the ratchet mechanism, and the positive rotation of the driving wheel 410 will drive the rotor of the power generation device 200 to rotate forward, thereby realizing power generation by the power generation device 200. In this scheme, the valve flap assembly 140 performs a 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 driving wheel 410, the driving wheel 410 will rotate relative to the mounting shaft 520 under the action of inertia, and the rotation angle of the driving wheel 410 is generally greater than 360 degrees; if no ratchet mechanism is provided between the mounting shaft 520 and the driving wheel 410, and the mounting shaft 520 and the driving wheel 410 are fixedly connected, the rotation angle of the driving wheel 410 is 360 degrees).

[0034] The transmission conversion device 300 converts the reciprocating linear movement of the valve flap assembly 140 into the reciprocating rotation of the installation shaft 520 (a ratchet mechanism needs to be set between the installation shaft 520 and the driving wheel 410 in this solution), then: during the forward rotation of the installation shaft 520, the installation shaft 520 will drive the driving wheel 410 to rotate forward under the action of the ratchet mechanism, and the forward rotation of the driving wheel 410 will drive the rotor of the power generation device 200 to rotate forward, so that the power generation device 200 generates electricity; during the reverse rotation of the installation shaft 520, the driving wheel 410 will continue to rotate forward under the action of inertia (that is, the driving wheel 410 will not rotate in the reverse direction with the installation shaft 520), and the corresponding rotor of the power generation device 200 will also continue to rotate forward under the drive of the driving wheel 410. In this solution, the valve flap assembly 140 performs a reciprocating linear movement, and the rotation angle of the forward rotation of the installation shaft 520 is less than 180 degrees, and the rotation angle of the reverse rotation of the installation shaft 520 is also less than 180 degrees.

[0035] In some embodiments, Figure 1 and Figure 2As shown, the transmission conversion device 300 includes an inclined first transmission member 310 and an inclined second transmission member 320, the mounting shaft 520 is horizontally arranged obliquely above the valve flap assembly 140, and the valve flap assembly 140 performs reciprocating linear movement in the up and down directions (two adjacent reciprocating linear movement processes can be performed continuously, that is, the interval is 0, and two adjacent reciprocating linear movement processes can also be performed at intervals, such as an interval of 0.2s or 0.5s or 1 second, etc.), the first transmission member 310 has a first hinge part and a second hinge part, the second transmission member 320 has a third hinge part and a mounting part 321, the first hinge part is hingedly connected to the valve flap assembly 140, the second hinge part is located obliquely above the first hinge part and is hingedly connected to the third hinge part, the mounting part 321 is located obliquely above the third hinge part and is fixedly connected to the mounting shaft 520, wherein in the horizontal direction, the mounting part 321 and the first hinge part are located on the same side of the second hinge part and the third hinge part. The first transmission member 310 and the second transmission member 320 may be a connecting rod 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 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.

[0036] The transmission conversion device 300 converts the reciprocating linear movement of the valve flap assembly 140 into the reciprocating rotation of the mounting shaft 520, then: It can be that, based on the valve flap assembly 140 moving linearly upward, the transmission conversion device 300 drives the installation shaft 520 to rotate in a one-way positive direction, and the installation shaft 520 drives the driving wheel 410 to rotate in a one-way positive direction through the ratchet mechanism, and the driving wheel 410 drives the rotor of the power generation device 200 to rotate. In this process, the rotation angle of the installation shaft 520 is less than 180 degrees; based on the valve flap assembly 140 moving linearly downward, the transmission conversion device 300 drives the installation shaft 520 to rotate in a one-way reverse direction, and the installation shaft 520 cannot drive the driving wheel 410 to rotate in a one-way reverse direction. The driving wheel 410 will continue to rotate in a one-way positive direction under the action of inertia, and the rotor of the power generation device 200 will continue to rotate under the drive of the driving wheel 410. In this process, the rotation angle of the installation shaft 520 is less than 180 degrees; in this scheme, the driving wheel 410 can be installed on the installation shaft 520 in a one-way positive rotation; Alternatively, based on the downward linear movement of the valve flap assembly 140, the transmission conversion device 300 drives the installation shaft 520 to rotate in a one-way reverse direction, and the installation shaft 520 drives the driving wheel 410 to rotate in a one-way reverse direction through the ratchet mechanism, and the driving wheel 410 drives the rotor of the power generation device 200 to rotate. In this process, the rotation angle of the installation shaft 520 is less than 180 degrees; based on the upward linear movement of the valve flap assembly 140, the transmission conversion device 300 drives the installation shaft 520 to rotate in a one-way forward direction, and the installation shaft 520 cannot drive the driving wheel 410 to rotate in a one-way forward direction. The driving wheel 410 will continue to rotate in a one-way reverse direction under the action of inertia, and the rotor of the power generation device 200 will continue to rotate under the drive of the driving wheel 410. In this process, the rotation angle of the installation shaft 520 is less than 180 degrees; in this scheme, the driving wheel 410 can be installed on the installation shaft 520 in a one-way reverse rotation; The rotation angle of the installation shaft 520 for one-way rotation may be set to 30 degrees; or the rotation angle of the installation shaft 520 for one-way rotation may be set to 60 degrees; or the rotation angle of the installation shaft 520 for one-way rotation may be set to 90 degrees; or the rotation angle of the installation shaft 520 for one-way rotation may be set to 120 degrees; or the rotation angle of the installation shaft 520 for one-way rotation may be set to 150 degrees, etc.; The above can all achieve the purpose of this application, and its purpose does not deviate from the design concept of the present invention, which will not be repeated here, and should all fall within the protection scope of this application.

[0037] The transmission conversion device 300 converts the reciprocating linear movement of the valve flap assembly 140 into a unidirectional positive rotation of the mounting shaft 520, then: The mounting shaft 520 is horizontally arranged directly above the valve flap assembly 140, and the second hinge part is hingedly connected to the third hinge part (not shown in this scheme diagram, when the valve flap assembly 140 is in the initial state, the first transmission member 310 and the second transmission member 320 are both vertically arranged in the up and down directions, and the first transmission member 310 is located directly below the second transmission member 320; wherein, the size of the first transmission member 310 in the up and down directions - the size of the second transmission member in the up and down directions = the absolute value of the maximum displacement of the valve flap assembly 140, the absolute value of the maximum displacement of the valve flap assembly 140 = the value of the maximum stroke of the valve flap assembly moving upward = the value of the maximum stroke of the valve flap assembly moving downward). Based on the upward linear movement of the valve flap assembly 140, the transmission conversion device 300 drives the installation shaft 520 to perform a one-way positive rotation, the installation shaft 520 drives the driving wheel 410 to perform a one-way positive rotation, and the driving wheel 410 drives the rotor of the power generation device 200 to rotate. In this process, the rotation angle of the installation shaft 520 is 180 degrees; based on the downward linear movement of the valve flap assembly 140, the transmission conversion device 300 drives the installation shaft 520 to continue to perform a one-way positive rotation, the installation shaft 520 drives the driving wheel 410 to continue to perform a one-way positive rotation, and the driving wheel 410 drives the rotor of the power generation device 200 to rotate. In this process, the rotation angle of the installation shaft 520 is 180 degrees; that is, the valve flap assembly 140 performs an up and down reciprocating movement. The mounting shaft 520 drives the driving wheel 410 to complete a unidirectional rotation with a rotation angle of 360 degrees (a ratchet mechanism is provided between the mounting shaft 520 and the driving wheel 410, then the driving wheel 410 will rotate relative to the mounting shaft 520 under the action of inertia, and the rotation angle of the mounting shaft 520 is 360 degrees, and the rotation angle of the driving wheel 410 is generally greater than 360 degrees; if there is no ratchet mechanism between the mounting shaft 520 and the driving wheel 410, and the mounting shaft 520 and the driving wheel 410 are fixedly connected, then the mounting shaft 520 and the driving wheel 410 rotate synchronously and the rotation angle is 360 degrees). This scheme can also 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 also belong to the protection scope of the present application.

[0038] In some embodiments, Figure 1 and Figure 2 As shown, the rotating transmission device 400 also includes: a driven wheel 420, which is arranged on the rotor of the power generation device 200 and is connected to the driving wheel 410.

When the driving gear rotates forward, the driven gear rotates in the reverse direction, and the rotor of the power generation device 200 rotates in the reverse direction. Alternatively, the driving wheel 410 may be a driving gear, and the driven gear 420 may be a driven gear. Figure 1 and Figure 2 As shown, the driving wheel 410 is a driving pulley, and the driven wheel 420 is a driven pulley, and the driving pulley and the driven pulley are connected by a transmission belt. When the driving pulley rotates forward, the driven pulley rotates forward, and the rotor of the generator 200 rotates forward; or the driving wheel 410 may be a driving sprocket, and the driven wheel 420 may be a driven sprocket, and the driving sprocket and the driven sprocket are connected by a transmission chain. When the driving sprocket rotates forward, the driven sprocket rotates forward, and the rotor of the generator 200 rotates forward; all of the above can 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 belong to the protection scope of the present application.

[0040] In some embodiments, Figure 1 and Figure 2 As shown, a connecting member 141 (such as a connecting rod) is protruded from the top of the valve flap assembly 140, and the first hinged portion is hingedly connected to the connecting member 141.

Among them, the transmission conversion device 300 includes a guide rail groove, an eccentric wheel, and an eccentric shaft on the eccentric wheel. This solution can also achieve the purpose of this application. Its purpose does not deviate from the design concept of the present invention and will not be repeated here. It should also fall within the protection scope of this application.
