Composite generation device based on direct-current water flow pulse vibration

Abstract

A composite generating device based on direct-current water flow pulse vibration relates to the technical field of fluid power machinery and comprises a tee joint, a first port of the tee joint is connected with a water outlet pipe, a second port of the tee joint is sleeved with a sealed elastic telescopic structure, and a third port of the tee joint is connected with a water inlet component; the inner top of the sealed elastic telescopic structure is connected with a plugging structure connecting rod, and the lower end of the plugging structure connecting rod is connected with a plugging structure used for plugging a water inlet port of the water outlet pipe. During intermittent and regular acceleration or deceleration of water flow in the plugging structure and the sealed elastic telescopic structure, the internal average water pressure is larger than the water pressure of straight-flow water due to the action of the water hammer, so that the water flow speed of discharged water is larger than the water outlet speed of the straight-flow water; due to the fact that the water flow of the pulse water is discontinuous, and the water flow of the straight-flow water is continuous, the flow of the pulse water flow is smaller than that of the straight-flow water under the conditions of the same water pressure, the same water outlet caliber and the same water outlet time, and the purpose of saving water is achieved.

Description

Technical Field

[0001] The invention relates to the technical field of fluid power machinery, and in particular to a composite generating device based on direct current water flow pulse vibration. Background Art

[0002] Existing pulse water flow devices mostly rely on external energy solenoid valves. For example, the existing patent CN202221444406.5 discloses a pulse water flow driven vibration device, whose motor drives a water pump or an electronic control module, and has problems such as high energy consumption, complex structure, and high cost.

[0003] In traditional technology, vibration requires additional devices (such as eccentric rotors or piezoelectric ceramics) to achieve, which is a vibration and pulse separation structure, resulting in system redundancy. Summary of the invention

[0004] The purpose of the present invention is to address the defects and shortcomings of the prior art and provide a composite generating device based on direct current water flow pulse vibration, which can directly convert direct current water into pulse water flow and generate vibration without external energy input and combined with the water hammer effect; when the water flow inside the blocking structure and the sealed elastic telescopic structure is accelerating or decelerating with an intermittent regularity, the internal average water pressure is greater than the water pressure of the direct current water due to the effect of the water hammer, so that the water flow rate of the outlet water is greater than the water flow rate of the direct current water; since the water flow of the pulse water is discontinuous, while the water flow of the direct current water is continuous, therefore, under the same water pressure, water outlet diameter and the same water outlet time, the flow rate of the pulse water flow is less than the flow rate of the direct current water, thereby achieving the purpose of saving water.

[0005] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: it comprises a tee, port one of the tee is connected to a water outlet pipe, port two is sleeved with a sealed elastic telescopic structure, and port three is connected to a water inlet component; the inner top of the sealed elastic telescopic structure is connected to a blocking structure connecting rod, and the lower end of the blocking structure connecting rod is connected to a blocking structure for blocking the water inlet port of the water outlet pipe.

[0006] Direct current water enters from port three of the tee and continuously moves toward the sealed elastic telescopic structure. The sealed elastic telescopic structure continuously expands and gradually pulls up the plugging structure through the connecting rod of the plugging structure. The water inlet port of the outlet pipe is gradually opened, and part of the water is diverted to the direction of the outlet pipe. As the degree of opening of the water inlet port of the outlet pipe gradually increases, the water flow velocity continues to increase, and the static pressure of the water inlet port of the outlet pipe continues to decrease. According to the Bernoulli principle, the plugging structure moves downward and recloses the water inlet port of the outlet pipe. The flowing water is instantly stopped, and the pressure inside the tee and the sealed elastic telescopic structure increases rapidly due to the water hammer effect. The sealed elastic telescopic structure is instantly lifted up and expanded to store pressure. When the pressure increases to a certain extent, the plugging structure is pulled up, and the water inlet port of the outlet pipe is reopened, entering the above cycle again, continuously interrupting the water flow, generating water hammer, creating water hammer pressure waves, forming pulsed water flow and generating vibration.

[0007] Preferably, the blocking structure may be a ball valve, a valve plate, etc.

[0008] Preferably, the sealed elastic telescopic structure may be an elastic bag or the like.

[0009] Preferably, the contact position between the water inlet port of the water outlet pipe and the blocking structure is an arc-shaped structure matched with the spherical surface of the blocking structure.

[0010] Preferably, the sealed elastic telescopic structure is sealed and fixed to the three-way sleeve joint by a clamp.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention provides a composite generating device based on direct current water flow pulse vibration, which can directly convert direct current water into pulse water flow and generate vibration without external energy input, combined with the water hammer effect; in the intermittent regular acceleration or deceleration of the water flow inside the blocking structure and the sealed elastic telescopic structure, the internal average water pressure is greater than the water pressure of the direct current water due to the effect of the water hammer, so that the water flow rate of the outlet water is greater than the water flow rate of the direct current water; since the water flow of the pulse water is discontinuous, while the water flow of the direct current water is continuous, therefore, under the same water pressure, water outlet diameter and the same water outlet time, the flow rate of the pulse water flow is less than the flow rate of the direct current water, thereby achieving the purpose of saving water.

[0018] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. The preferred embodiments in the description are only used as examples, and all other embodiments obtained by those skilled in the art without making any creative work are within the scope of protection of the present invention.

[0019] like Figure 1-Figure 3 As shown, this specific embodiment adopts the following technical scheme: it comprises a tee 1, port one of the tee 1 is connected to a water outlet pipe 3; port two is sleeved with a sealed elastic telescopic structure 2, and the sleeved position is sealed and fixed by a clamp, and the sealed elastic telescopic structure is an elastic bag; port three is connected to a water inlet component; the inner top of the sealed elastic telescopic structure 2 is connected with a blocking structure connecting rod 5, and the lower end of the blocking structure connecting rod 5 is connected to a blocking structure 4 for blocking the water inlet port of the water outlet pipe 3, and the blocking structure 4 is a ball valve. When it is a ball valve, the contact position between the water inlet port of the water outlet pipe 3 and the blocking structure 4 is an arc structure adapted to the spherical surface of the blocking structure 4.

[0020] When the present invention is used, direct current water enters from port three of the tee 1 and continuously moves toward the sealed elastic telescopic structure 2. The sealed elastic telescopic structure 2 continuously expands and gradually pulls up the plugging structure 4 through the plugging structure connecting rod 5. The water inlet port of the water outlet pipe 3 is gradually opened, and a part of the water is diverted to the water outlet pipe 3. As the degree to which the water inlet port of the water outlet pipe 3 is opened gradually increases, the water flow velocity continuously increases, and the static pressure at the water inlet port of the water outlet pipe 3 continuously decreases. According to the Bernoulli principle, the plugging structure 4 moves downward and recloses the water inlet port of the water outlet pipe 3. The flowing water flow is instantly stopped. The pressure inside the tee 1 and the sealed elastic telescopic structure 2 increases rapidly due to the water hammer effect. The sealed elastic telescopic structure 2 is instantly lifted up and expanded to store pressure. When the pressure increases to a certain extent, the plugging structure 4 is pulled up, and the water inlet port of the water outlet pipe 3 is reopened, and the above cycle is entered again, continuously interrupting the water flow, generating water hammer, creating water hammer pressure waves, forming pulsed water flow and generating vibration.

[0021] Compared with the prior art, the present invention has the following beneficial effects: Efficient use of energy: Direct current water can be directly converted into pulsed water flow and generate vibration without external energy input.

[0022] Significant pressure increase: By utilizing the water hammer effect and the continuous pressure of the sealed elastic telescopic structure, the outlet peak pressure can be significantly increased.

[0023] Water saving: When the water flow inside the blocking structure and the sealed elastic telescopic structure accelerates or decelerates intermittently, the internal average water pressure is greater than that of direct current water due to the effect of water hammer, making the water flow rate of the outlet water greater than that of direct current water; since the flow of pulse water is discontinuous, while the flow of direct current water is continuous, therefore, under the same water pressure, outlet diameter and water outlet time, the flow rate of pulse water flow is smaller than that of direct current water, thus achieving the purpose of water saving.

[0024] Strong environmental adaptability: The circuit-free design can work stably in harsh environments such as humidity and high temperature.

[0025] Example 1: See Figure 4 In this embodiment, the composite generating device is installed on the spray gun pipeline. Figure 4 As shown, the port three of the tee 1 is connected to the water inlet pipe 7 of the spray gun, and the spray gun head 6 is connected to the water outlet pipe 3. At this time, the direct water can be converted into a pulsed high-pressure water flow, which is flushed out from the spray gun head 6, while saving water and generating vibration.

[0026] Example 2: See Figure 5 In this embodiment, the composite generating device is installed on the shower pipe. Figure 5 As shown, the port three of the tee 1 is connected to the shower water pipe 8, and the shower head 9 is connected to the water outlet pipe 3. At this time, the direct water can be converted into a pulsed high-pressure water flow, which is flushed out from the shower head 9, while saving water and generating vibration.

[0027] For those skilled in the art, they can modify the technical solutions described in the aforementioned embodiments and make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
