Technical Field
The invention relates to the field of pipelines, in particular to a water pipe system.
Background
For water pipe systems, the tap water it supplies is typically used for drinking or washing; in the aspect of washing, the existing water pipe system completely depends on the washing capacity of the water body, so that the washing capacity of the existing water pipe system is limited for the scale on the surface of an object.
On the other hand, in the aspect of removing the scale, at present, many ultrasonic cleaning devices are provided, but all the ultrasonic cleaning devices belong to independent devices, are difficult to transfer and use flexibly and have high cost.
Disclosure of Invention
In view of the above problems, an object of the present invention is to provide an ultrasonic pipe system, which can significantly improve the scale removal capability by washing with ultrasonic auxiliary tap water; and in addition, tap water containing ultrasonic waves can be formed at each water supply end in the system, so that the system is extremely convenient to use and very low in cost.
The technical scheme adopted by the invention for solving the technical problems is as follows: the ultrasonic pipeline system comprises a water pipe network, wherein an ultrasonic joint is connected in series in a water inlet main pipe of the water pipe network, the ultrasonic joint comprises a connecting pipe, an annular ultrasonic transducer is arranged in the connecting pipe, a central through hole of the ultrasonic transducer can enable water in the water inlet main pipe to freely flow through, and the ultrasonic emission direction of the ultrasonic transducer is consistent with the water flow direction; and a water flow sensor is also arranged in the connecting pipe, and when the water flow sensor detects that the water body flows, the ultrasonic transducer is triggered to work, otherwise, the ultrasonic transducer stops working.
Preferably, an electrical box is arranged outside the ultrasonic joint, the electrical box comprises a power module and a control module, the control module is electrically coupled with the water flow sensor and the ultrasonic transducer, the control module enables the ultrasonic transducer to keep a working state when receiving a water flow signal of the water flow sensor, and otherwise, the ultrasonic transducer stops working.
Preferably, the aperture of the central through hole of the ultrasonic transducer is smaller than the inner diameter of the water inlet main pipe; the water flow sensor comprises a first electronic pressure gauge and a second electronic pressure gauge which are arranged on two sides of the ultrasonic transducer; when the first electronic pressure gauge and the second electronic pressure gauge generate pressure difference, water flow is judged to exist in the water inlet main pipe, and otherwise, no water flow is judged; the design principle of the water flow sensor is as follows: under the condition of no water flow, the water pressure in the water inlet main pipe is equal everywhere, and under the condition of water flow, the water pressure at the downstream of the ultrasonic transducer is lower than the water pressure at the upstream due to the throttling effect of the central through hole of the ultrasonic transducer on the water flow, so that a pressure difference is formed; the water flow sensor is simple in structure, stable in performance and not easy to damage.
Preferably, a cover is covered on the upstream side of the central through hole of the ultrasonic transducer, the bottom surface of the cover is formed by a hard plate, and water through holes are uniformly distributed on the side surface of the cover in the circumferential direction, so that water in the upstream direction of the ultrasonic transducer enters the cover from the side wall of the cover and then passes through the central through hole of the ultrasonic transducer; according to the scheme, after the ultrasonic waves reflected from the downstream pass through the central through hole of the ultrasonic transducer, the ultrasonic waves are reflected by the bottom surface of the cover and then are emitted to the downstream again due to high frequency, short wavelength and weak diffraction capability, so that the ultrasonic wave intensity of the downstream water end is enhanced.
Preferably, in the ultrasonic pipeline system, the nodes of each branch are connected by a special three-way pipe; the special three-way pipe comprises a circular cavity, a main pipe, a first branch pipe and a second branch pipe, wherein the main pipe, the first branch pipe and the second branch pipe are connected to the side surface of the circular cavity in a T shape; a rotating plate which extends along the diameter direction and takes the circle center of the circular cavity as the rotating center is arranged in the circular cavity; when the rotating plate rotates to a first limit position in the circular cavity, the main pipe is communicated with the first branch pipe, and a passage between the main pipe and the second branch pipe is blocked by the rotating plate; when the rotating plate rotates to a second limit position in the circular cavity, the main pipe is communicated with the second branch pipe, and a passage between the main pipe and the first branch pipe is blocked by the rotating plate.
The invention has the beneficial effects that: when the ultrasonic pipeline system is used, when a tap of any water terminal in a water pipe network is opened, water flow is generated in a water inlet main pipe, so that the ultrasonic transducer works, ultrasonic waves generated by the ultrasonic transducer are transmitted to the downstream in the water pipe, and the wall of the water pipe forms a reflecting wall, so that the ultrasonic waves are always constrained in the water pipe; when the water pipe turns, the ultrasonic waves are reflected together with the water flow on the arc-shaped inner wall of the elbow and flow to the water using terminal together with the water flow, so that the ultrasonic waves directly act on the water flow washing surface of the water using terminal, and the scale is favorably eliminated; the system only connects an ultrasonic joint in series in the water inlet main pipe, so that any water terminal in the whole water pipe network can obtain the ultrasonic flushing effect, the cost is extremely low, and the use is extremely convenient.

Detailed Description
The invention is further illustrated with reference to the following figures and examples:
the first embodiment is as follows:
the ultrasonic pipeline system comprises a water pipe network, wherein an ultrasonic joint is connected in series in a water inlet main pipe of the water pipe network, the embodiment of the ultrasonic joint is shown in figure 1, the ultrasonic joint 2 comprises a connecting pipe 21, an annular ultrasonic transducer 22 is clamped in the connecting pipe 21, a central through hole 220 of the ultrasonic transducer 22 can enable water in the water inlet main pipe 1 to freely flow through, the ultrasonic emission direction of the ultrasonic transducer 22 is consistent with the water flow direction, and the ultrasonic emission direction and the water flow direction are towards the downstream of the water inlet main pipe 1 as shown by arrows in figure 1; a water flow sensor is further arranged in the connecting pipe 21, and when the water flow sensor detects that the water body flows, the ultrasonic transducer 22 is triggered to work, otherwise, the ultrasonic transducer 22 stops working.
In the first embodiment, the aperture of the central through hole 220 of the ultrasonic transducer 22 is smaller than the inner diameter of the water inlet main 1; the water flow sensor comprises a first electronic pressure gauge 31 and a second electronic pressure gauge 32 which are arranged on two sides of the ultrasonic transducer 22; when the first and second electronic pressure gauges 31 and 32 generate pressure difference, it is determined that water flows in the water inlet main pipe 1, otherwise, it is determined that no water flows; the design principle of the water flow sensor is as follows: in the state of no water flow, the water pressure in the water inlet manifold 1 is equal everywhere, and in the state of water flow, the water pressure at the downstream of the ultrasonic transducer 22 is lower than the water pressure at the upstream due to the throttling effect of the central through hole 220 of the ultrasonic transducer 22 on the water flow, so that a pressure difference is formed; the water flow sensor is simple in structure, stable in performance and not easy to damage.
An electrical box 4 is arranged outside the ultrasonic joint 2, a power module and a control module are arranged in the electrical box 4, the control module is electrically coupled with the first and second electronic pressure gauges 31 and 32 and the ultrasonic transducer 22, the control module performs difference operation on the pressure intensities output by the first and second electronic pressure gauges 31 and 32, and if the difference value is greater than a set value (considering normal circuit deviation, neglecting the deviation, the set value is zero), it is determined that water flow exists in the water inlet main pipe 1, and the ultrasonic transducer 22 works; if the difference is smaller than the set value, determining that no water flow exists in the water inlet main pipe 1, and stopping the ultrasonic transducer 22; the power module supplies power to each electronic component.
When the water tap of any water terminal in the water pipe network is opened in the use process of the ultrasonic pipeline system, water flow is generated in the water inlet main pipe 1, so that the ultrasonic transducer 22 works, the generated ultrasonic waves are transmitted to the downstream in the water pipe, and the wall of the water pipe forms a reflecting wall, so that the ultrasonic waves are always restricted in the water pipe; when the water pipe turns, the ultrasonic waves are reflected together with the water flow on the arc-shaped inner wall of the elbow and flow to the water using terminal together with the water flow, so that the ultrasonic waves directly act on the water flow washing surface of the water using terminal, and the scale is favorably eliminated; the system only connects one ultrasonic joint 2 in series in the water inlet main pipe 1, so that any water terminal in the whole water pipe network can obtain the ultrasonic flushing effect, the cost is extremely low, and the use is extremely convenient.
In addition, a switch can be associated with the ultrasonic transducer 22, which can be arranged on the electrical box 4; when people who are sensitive to ultrasonic waves, such as pregnant women, do not want to contact any ultrasonic waves, the ultrasonic transducer 22 can be directly turned off.
Example two:
fig. 2 shows a second embodiment of the ultrasonic joint 2, which is different from the first embodiment in that the upstream side of the central through hole 220 of the ultrasonic transducer 22 is covered with a cover 5, the bottom surface of the cover 5 is made of a hard plate, and the lateral surface is circumferentially and uniformly distributed with water through holes 50, so that water in the upstream direction of the ultrasonic transducer 22 enters the cover from the lateral wall of the cover 5 and then passes through the central through hole 220 of the ultrasonic transducer; for the ultrasonic waves reflected from the downstream, after passing through the central through hole 220 of the ultrasonic transducer, the ultrasonic waves are reflected by the bottom surface of the cover 5 and then emitted to the downstream again until being emitted along with water flow from a water tap at the water using end due to high frequency, short wavelength and weak diffraction capability; thereby inhibiting the ultrasonic wave from reflecting upstream and enhancing the ultrasonic wave intensity at the downstream water end.
In addition, for the ultrasonic pipeline system, the nodes of each branch can be connected by adopting a special three-way pipe; one embodiment of the special tee is shown in fig. 3 and 4, and comprises a circular cavity 600, a header pipe 60, a first branch pipe 61 and a second branch pipe 62 which are connected to the side surface of the circular cavity in a T shape; a rotating plate 63 which extends along the diameter direction and takes the circle center of the circular cavity 600 as the rotating center is arranged in the circular cavity 600; in the circular cavity 600, a first limiting block 641 and a second limiting block 642 are respectively arranged at the joints of the main pipe 60, the first branch pipe 61 and the second branch pipe 62; when the rotating plate 63 rotates to the first limit position in the circular cavity 600, the main pipe 60 is communicated with the first branch pipe 61, and the passage between the main pipe 60 and the second branch pipe 62 is blocked by the rotating plate 63, namely, the state shown in fig. 3; when the rotating plate 63 rotates to the second limit position in the circular cavity, the main pipe 60 communicates with the second branch pipe 62, and the passage between the main pipe 60 and the first branch pipe 61 is blocked by the rotating plate 63, that is, as shown in fig. 4. As for the special three-way pipe, as is apparent from fig. 3 and 4, if there is water flow at the water using end corresponding to the first branch pipe 61 and there is no water flow at the water using end corresponding to the second branch pipe 62, the pressure in the first branch pipe 61 is reduced, so that the water in the main pipe 60 pushes the rotating plate 63 to rotate to the first limit position, i.e. the position shown in fig. 3, thereby blocking the passage between the main pipe 60 and the second branch pipe 62, which causes the ultrasonic waves to be directly reflected on the rotating plate 63 to the first branch pipe 61 without entering the second branch pipe 62, and greatly reduces the midway loss of the ultrasonic waves; when there is water flow at the water using end corresponding to the second branch pipe 62 and there is no water flow at the water using end corresponding to the first branch pipe 61, the ultrasonic waves are directly transmitted to the water using end corresponding to the second branch pipe 62 in the same manner.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, but rather as the subject matter of the invention is intended to cover all modifications, equivalents and alternatives falling within the spirit and scope of the present invention.
