The current water hammer pump is composed of water pipe, water delivery valve, water discharge valve and air cylinder. Water flows into the water pipe from the inlet pipe, and the water discharge valve is closed under the impact of water. Water continuously flows in, the pressure in the water pipe rises, the water outlet valve is opened by the water flow, and part of the water enters the air cylinder.

[0035] Please refer to Figures 1 to 4 The utility model embodiment provides a water hammer generating device of adjustable water pressure, comprising:

[0036] Water inlet pipe 10 and water outlet pipe 15;

[0037] Energy storage tank 11, energy storage tank 11 with the first end communication of water inlet pipe 10;

[0038] Water wheel 12, including shell 121 and rotation installation in shell 121 water wheel 122, the lower part of shell 121 is equipped with with water inlet pipe 10 communication import 123, the water that flows into import 123 can drive water wheel 122 rotation, the upper part of shell 121 is equipped with with water outlet pipe 15 communication export 124;

[0039] Regulating valve 16, between import 123 and water inlet pipe 10, or water wheel 12 export 124 and water outlet pipe 15 between;

[0040] Rotor cavity 13, rotor cavity 13 is equipped with oppositely arranged first connecting port 131 and second connecting port 132, first connecting port 131 with the second end communication of water inlet pipe 10, second connecting port 132 with the first end communication of water outlet pipe 15;

[0041] Driven rotor 14, in rotor cavity 13, the outer periphery of driven rotor 14 and the inner wall of rotor cavity 13 slide and abut, the shaft core of driven rotor 14 and the shaft core of water wheel 122 fixed connection, driven rotor 14 is provided with the water channel 141 of the first connecting port 131 and the second connecting port 132 can be communicated and the entity part 143 of the first connecting port 131 and the second connecting port 132 can be cut off.

[0042] Please refer to Figure 2Specifically, the water inlet pipe 10 is in a straight tube shape, the first end of the water inlet pipe 10 is used as the water inlet 101, and the end of the second end of the water inlet pipe 10 is communicated with the first connecting port 131 of the rotor cavity 13, so that the flow channel of the energy storage tank 11 to the first connecting port 131 of the rotor cavity 13 is straight, which helps the water to quickly flow into the water outlet channel 141.

[0043] The water outlet pipe 15 is in a straight tube shape, the end of the first end of the water outlet pipe 15 is communicated with the second connecting port 132 of the rotor cavity 13, and the other end is used as the water outlet 152. The flow channel of the second connecting port 132 to the water outlet 152 is straight, which helps the water to smoothly flow from the second connecting port 132 to the water outlet 152.

[0044] The shell 121 of the embodiment is in a substantially cylindrical shape, the end face of one end of the shell 121 is in abutment with the rotor cavity 13, the inlet 123 and the outlet 124 are arranged on the outer periphery of the shell 121, and the inlet 123 and the outlet 124 are oppositely arranged. When the water flow flows from the inlet 123 of the water wheel 12, the water flow impacts the paddle 1222 of the water wheel 122, so that the water wheel 122 rotates in the shell 121, and the water flow is transmitted to the outlet 124 of the water wheel 12 through the paddle 1222. Since the water flow is continuous, the water wheel 122 can rotate all the time.

[0045] The shaft core of the water wheel 122 is located in the middle of the water wheel 122, and the water wheel 122 rotates in the shell 121 through the shaft core.

[0046] Please refer to Figure 3 The shaft core of the driven rotor 14 is fixedly connected with the shaft core of the water wheel 122, which means that the driven rotor 14 is provided with the shaft 142 at both ends, the shaft 142 close to one end of the shell 121 penetrates the rotor cavity 13 and extends into the shell 121, and is fixedly connected with the middle part of the water wheel 122, so that the driven rotor 14 and the water wheel 122 can rotate synchronously.

[0047] The driven rotor 14 is in a substantially cylindrical shape, and the shaft 142 is arranged at both ends of the cylinder. Preferably, the shaft 142 at both ends is located on the axis of the driven rotor 14, the water outlet channel 141 is open through both sides of the outer periphery of the driven rotor 14, one end of the water outlet channel 141 is communicated with the first connecting port 131, and the other end is communicated with the second connecting port 132. Preferably, the extension direction of the water outlet channel 141 at both ends is parallel to the radial line of the driven rotor 14.

[0048] Specifically, the solid part 143 is the part of the driven rotor 14 without the water outlet channel 141.

[0049] Specifically, the water wheel 122 comprises a runner 1221 and a plurality of paddles 1222 fixed to the outer periphery of the runner 1221, and the end of the paddle 1222 away from the runner 1221 and the two side walls of the paddle 1222 are in sliding abutment with the inner wall of the shell 121, so that after the water flow enters the shell 121, it can only push the paddle 1222 to rotate, thereby being transmitted to the outlet 124 of the shell 121. The runner 1221 in this embodiment is the shaft core of the water wheel 122.

[0050] One end of the plurality of paddles 1222 is fixed to the outer periphery of the runner 1221, and the other end extends outward, and preferably, the plurality of paddles 1222 can be arranged at equal intervals in the circumferential direction.

[0051] Specifically, the middle part of the runner 1221 is provided with a mounting hole 12211 for mounting the rotating shaft 142. The rotating shaft 142 of the driven rotor 14 extends into the shell 121 and is inserted into the mounting hole 12211. The shape of the mounting hole 12211 matches the cross-sectional shape of the rotating shaft 142. In this embodiment, the mounting hole 12211 is a circular hole, and the cross-sectional shape of the rotating shaft 142 is also circular. More specifically, the hole diameter of the mounting hole 12211 can be slightly smaller than the outer diameter of the rotating shaft 142, so that the rotating shaft 142 can be in interference fit with the mounting hole 12211, and the rotating shaft 142 can be driven to rotate synchronously only when the water wheel 122 rotates. In other embodiments, the cross-sectional shape of the rotating shaft 142 can also be shaped, specifically square, rectangular, trapezoidal, prismatic, triangular, pentagonal, hexagonal, or irregular rectangular, polygonal, etc. If the cross-sectional shape of the rotating shaft 142 is square, the mounting hole 12211 can also be square to match the cross-sectional shape of the rotating shaft 142. Since the rotating shaft 142 is not easy to slip when rotating in the square hole, the rotating shaft 142 can be in clearance fit with the mounting hole 12211.

[0052] Specifically, the rotor cavity 13 abuts one side of the shell 121, and the first opening 133 for mounting the driven rotor 14 is provided on the side of the rotor cavity 13 close to the shell 121. The diameter of the first opening 133 can be greater than or equal to the outer diameter of the driven rotor 14, so that the driven rotor 14 can be easily mounted into the rotor cavity 13 from the first opening 133, and a through hole does not need to be separately provided on the side wall of the rotor cavity 13 for the one end of the rotating shaft 142 to extend into the shell 121.

[0053] In this embodiment, the combination of the rotor cavity 13 and the driven rotor 14 forms a valve, and the valve switches between opening and closing to achieve the water hammer effect. As shown in Figure 5 Specifically, when the driven rotor 14 rotates to the two ends of the water passage 141 and is in abutment with the first connecting port 131 and the second connecting port 132 respectively, the first connecting port 131 is in communication with the second connecting port 132 through the water passage 141, which is equivalent to the valve being opened; as shown in Figure 6As shown, when the driven rotor 14 rotates to the two ends of the water passage 141 staggered with the first connecting port 131 and the second connecting port 132, the first connecting port 131 is blocked by the solid part 143, so that the first connecting port 131 is not communicated with the second connecting port 132, which is equivalent to the valve being closed.

[0054] Specifically, the energy storage tank 11 has a second opening 111, which is vertically arranged and downwardly directed, and is communicated with the first end of the water inlet pipe 10. When the valve at the rear end of the energy storage tank 11 is closed, the water inlet pipe 10 supplies water, and the energy storage tank 11 starts to fill with water, the original air in the energy storage tank 11 is compressed, and the kinetic energy of the water is stored. When the valve is quickly opened, the kinetic energy stored in the energy storage tank 11 is released, forcing the water to flow out at a high speed. Through repeated cycles, a pulsed high-pressure water flow can be formed at the water outlet 152 of the water outlet pipe 15.

[0055] The adjusting valve 16 of the present embodiment is arranged between the inlet 123 of the water wheel 12 and the water inlet pipe 10, or between the outlet 124 of the water wheel 12 and the water outlet pipe 15. The water inlet pipe 10 of the present embodiment is communicated with the water outlet pipe 15 through the water passage 141, serving as a main pipeline. The water inlet pipe 10 is communicated with the water outlet pipe 15 through the water wheel 12, serving as a bypass pipeline. The adjusting valve 16 is arranged on the bypass pipeline, and the rotating speed of the water wheel 12 is controlled through the adjusting valve 16. The rotating speed of the water wheel 12 determines the rotating speed of the driven rotor 14, which determines the time ratio of the water flow being cut off and communicated in the main pipeline, so as to infinitely adjust the pressure and flow rate of the water outlet 152.

[0056] When it is necessary to increase the pressure of the water outlet 152, the water flow of the water wheel 12 is reduced through the adjusting valve 16, the rotating speed of the water wheel 12 is slowed down, the energy storage time of the water inlet pipe 10 and the energy storage tank 11 is lengthened, the water kinetic energy is increased, and when the water outlet 152 is released, the pressure of the water outlet 152 is increased, and the water flow rate of the water outlet 152 is fast. According to the characteristics of fluid motion, the water wheel 12 and the water outlet pipe 15 have a vacuum pumping effect, which promotes the instantaneous speed of the water wheel 12 to be faster, so as to close the rotor water passage 141 faster. Conversely, when it is necessary to increase the water flow pulse frequency, the water flow of the water wheel 12 is increased through the adjusting valve 16, the rotating speed of the water wheel 12 is increased, the water flow rate in the water inlet pipe 10 is low, and there is no vacuum pumping effect, which does not affect the rotating speed of the water wheel 12, so as to increase the flow rate of the water outlet 152.

[0057] The utility model discloses a water hammer generating device, which comprises a water inlet pipe 10, a water storage tank 11, a water wheel 12, a driven rotor 14, a rotor cavity 13, a first connecting port 131, a second connecting port 132, a water outlet pipe 15, a water outlet 152 and a water channel 141.

[0058] The water hammer effect is formed by the conduction or interruption of the water channel 141 and the first connecting port 131 and the second connecting port 132. When the driven rotor 14 rotates to the state that the two ends of the water channel 141 are staggered with the first connecting port 131 and the second connecting port 132, the first connecting port 131 is blocked by the solid part 143, so that the first connecting port 131 and the second connecting port 132 are not connected, the water flow in the water storage tank 11 is more and more, the air in the water storage tank 11 is compressed, and the kinetic energy of the water is stored. When the driven rotor 14 rotates to the state that the two ends of the water channel 141 are connected with the first connecting port 131 and the second connecting port 132, the kinetic energy stored in the water storage tank 11 is released, so that the water flow is forced to flow out at high speed, the water flow in the water inlet pipe 10 can flow through the water channel 141 and enter the water outlet pipe 15, and then flow out from the water outlet 152. The water hammer generating device of the utility model does not discharge water, can be applied to the working condition that cannot discharge water, makes the water flow be fully utilized, has high transmission efficiency, and does not waste water source.

[0059] The water hammer generating device of the utility model adopts the adjusting valve 16 arranged at the inlet 123 or the outlet 124 of the water wheel 12 to control the rotation speed of the driven rotor 14, and then control the time ratio of the water flow conduction and interruption of the water channel 141, so as to control the pressure and flow of the water outlet 152, so that the pressure of the water outlet 152 can reach several times of the pressure of the water inlet 101 without increasing the power of the water pump and reducing the flow, and the pressure of the water outlet 152 can be infinitely adjusted according to the requirement.

[0060] Specifically, the first butt joint 102 for connecting the inlet 123 of the water wheel 12 is arranged on the side wall of the water inlet pipe 10, and the caliber of the first butt joint 102 is smaller than the caliber of the second end of the water inlet pipe 10; the second butt joint 151 for connecting the outlet 124 of the water wheel 12 is arranged on the side wall of the water outlet pipe 15, and the caliber of the second butt joint 151 is smaller than the caliber of the first end of the water outlet pipe 15, so that the pipe diameter of the water wheel inlet pipe 17 is smaller than the pipe diameter of the water inlet pipe 10, and the pipe diameter of the water wheel outlet pipe 18 is smaller than the pipe diameter of the water outlet pipe 15.

[0061] The water hammer generating device also includes a water turbine inlet pipe 17 and a water turbine outlet pipe 18. The inlet 123 of the water turbine 12 is connected to the second end of the inlet pipe 10 through the water turbine inlet pipe 17, and the outlet 124 of the water turbine 12 is connected to the first end of the outlet pipe 15 through the water turbine outlet pipe 18. A regulating valve 16 is provided on the water turbine inlet pipe 17 or the water turbine outlet pipe 18. Specifically, one end of the water turbine inlet pipe 17 is fixedly connected to the first pair of interfaces 102, and the other end is fixedly connected to the inlet 123 of the water turbine 12; one end of the water turbine outlet pipe 18 is fixedly connected to the outlet 124 of the water turbine 12, and the other end is fixedly connected to the second pair of interfaces 151.

[0062] like Figure 4 As shown, in this embodiment, the diameter of the first connection port 131 matches the opening of the water channel 141, and the opening area of ​​the water channel 141 is larger than the cross-sectional area of ​​the inlet pipe 10. The first connection port 131 is connected to the inlet pipe 10 through the first reducing sleeve 134. The diameter of the second connection port 132 is larger than the diameter of the outlet pipe 15. The second connection port 132 is connected to the outlet pipe 15 through the second reducing sleeve 135. The diameter of the first reducing sleeve 134 gradually narrows from one end near the first connection port 131 to the other end, and the diameter of the second reducing sleeve 135 gradually narrows from one end near the second connection port 132 to the other end.

[0063] The outer diameters of the first connecting port 131 and the second connecting port 132 can be equal, making the structures of the first reducing sleeve 134 and the second reducing sleeve 135 identical, thus unifying the structural type and reducing costs. The first reducing sleeve 134 is fitted over the first connecting port 131, with the diameter of the first reducing sleeve 134 near the first connecting port 131 being larger than the diameter of the other end. The larger diameters of the first reducing sleeve 134 near the first connecting port 131 and the second reducing sleeve 135 near the second connecting port 132 allow water to flow through more quickly.

[0064] Specifically, the cross-sectional shape of the water passage 141 is flat. The cross-sectional shape of the water passage 141 can be rectangular, elliptical, or oblong, etc. In this embodiment, the cross-sectional shape of the water passage 141 is rectangular. The opening area of ​​the water passage 141 is the cross-sectional area of ​​the water passage 141. The cross-sectional area of ​​the water passage 141 is larger than the cross-sectional area of ​​the inlet pipe 10 to ensure that when the inlet pipe 10 and the outlet pipe 15 are connected, the water in the inlet pipe 10 can quickly pass through the water passage 141. In this embodiment, the opening of the water passage 141 is rectangular. The length direction of the opening of the water passage 141 is parallel to the axial direction of the driven rotor 14. The water passage 141 is radially continuous. When the water passage 141 rotates to be horizontal with the inlet pipe 10 and the outlet pipe 15, the two ends of the water passage 141 are connected to the first connection port 131 and the second connection port 132, respectively.

[0065] More specifically, the height of the water passage 141 is less than or equal to one sixth of the outer diameter of the driven rotor 14 to ensure that the water hammer pressure is formed within 1 second, that is, the water outlet time is 6 seconds or more.

[0066] The working principle of the utility model is:

[0067] When the water flows through the water inlet pipe 10, part of the water flows to the energy storage tank 11, part of the water flows to the first connecting port 131, and the other part of the water flows to the water wheel 12. The rotation of the water wheel 12 can drive the synchronous rotation of the driven rotor 14. The driven rotor 14 is provided with a radial flat water passage 141. When the water passage 141 is rotated to be horizontal with the water inlet pipe 10 and the water outlet pipe 15, the water inlet pipe 10 is connected with the water outlet pipe 15 through the water passage 141. When the water passage 141 is rotated to be staggered with the water inlet pipe 10 and the water outlet pipe 15, the first connecting port 131 of the water inlet pipe 10 is blocked by the solid part 143.

[0068] When the water passage 141 is staggered with the first connecting port 131 and the second connecting port 132 at both ends, the water flow into the energy storage tank 11 is more and more, the air in the energy storage tank 11 is compressed, and the kinetic energy of the water is stored. Since the water wheel 12 continues to rotate, the water wheel 12 continues to drive the rotation of the driven rotor 14. When the water passage 141 is rotated to be connected with the water inlet pipe 10 and the water outlet pipe 15, the kinetic energy stored in the energy storage tank 11 is released, forcing the water to flow out at high speed. The water flow in the water inlet pipe 10 can flow through the water passage 141 into the water outlet pipe 15 and flow out from the water outlet 152. The cycle is repeated, and a pulse high pressure water flow can be formed at the water outlet 152 of the water outlet pipe 15. And the rotation speed of the water wheel 12 is adjusted by the regulating valve 16, and then the water quantity stored in the energy storage tank 11 is controlled, so as to control the pressure and flow of the water outlet 152.
