Description

Technical Field

[0001] This invention relates to the field of pipeline leak detection equipment technology, and in particular to an intelligent alarm device for water supply and drainage pipelines. Background Technology

[0002] Water supply and drainage pipeline engineering is a pipeline (channel) system engineering for transporting and distributing industrial water supply and domestic drinking water, as well as collecting, transporting and discharging industrial wastewater, domestic sewage and rainwater. Indoor pipelines used for transporting water resources are prone to leakage at pipeline valves or outlet pipes after long-term use, which leads to the waste of water resources. Moreover, pipeline leaks are not easily detected by people, which often results in a large amount of water seeping into the room, causing more serious property damage.

[0003] An existing patent (publication number: CN110388571B) discloses an indoor pipe leak prevention device, including a valve, the valve having a rotatable rotating handle inside, a screw fixed at the bottom end of the rotating handle, the screw being connected to the valve by a thread, and a water inlet pipe opening to the left inside the valve;

[0004] In the process of realizing this invention, the inventors discovered the following problems with the prior art: 1. The existing device uses a lot of internal integrated electronic circuits, which results in slow control and processing speed and insensitivity; 2. The device has a relatively simple control over the flow of water in the pipeline, which leads to the inability to effectively cut off the flow in the outlet pipe. Summary of the Invention

[0005] The purpose of this invention is to solve the problems of slow leak detection and low interception effect in the prior art, and to propose an intelligent alarm device for water supply and drainage pipelines.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0011] The above technical solution further includes:

[0012] A drive rod is fixedly provided at the upper middle part of the baffle plate. Two water-stop plates are fixedly provided inside the water-stop shell. The upper end face of the uppermost water-stop plate is in contact with the upper part of the inside of the water-stop shell, and the lower end face of the lowermost water-stop plate is in contact with the bottom of the water-stop shell.

[0013] An L-shaped hinge seat is fixedly provided at the upper end of the drive rod and outside the water-stop shell. The flow guiding assembly also includes connecting rings symmetrically fixed at both ends of the control box, and the two connecting rings are respectively connected to the interior of the two control cylinders.

[0014] The above technical solution further includes:

[0015] The drive assembly includes a bidirectional lead screw rotatably disposed on one side inside the control box. A worm gear is fixedly disposed in the middle of the bidirectional lead screw. Two threaded seats are also symmetrically disposed in the middle of the bidirectional lead screw via a threaded connection. Two limiting sliders are symmetrically slidably disposed on the inner wall of the control box. A fixing rod is fixed between the limiting slider and the threaded seat on the same side. A rotating rod is rotatably disposed in the middle of the fixing rod. The other end of the rotating rod is hinged to the middle of the L-shaped hinge seat.

[0016] The drive assembly also includes a housing fixedly disposed in the middle of the upper part of the control box. A worm gear is rotatably disposed inside the housing, and the worm gear meshes with a worm wheel. A drive motor is fixedly disposed at one end of the housing, and the output end of the drive motor is fixedly connected to one end of the worm gear. An operating turntable is fixedly disposed at the other end of the worm gear outside the housing.

[0017] The above technical solution further includes:

[0018] The detection assembly includes a connecting pipe fixedly disposed between two control cylinders, the connecting pipe being interconnected with the two control cylinders, a throttling plate fixedly disposed inside the connecting pipe, a U-shaped throttling element fixedly disposed at the upper middle part of the connecting pipe, two metal sliders symmetrically sliding inside the U-shaped throttling element, the metal sliders being cylindrical in shape, and a liquid working medium being filled inside the U-shaped throttling element and located between the two metal sliders.

Due to the worm gear and worm wheel configuration of the drive component, the entire drive structure has a large self-locking property, effectively preventing the water flow from impacting the baffles and causing them to shake. This solves the problem of unsatisfactory flow interception effect in traditional methods. At the same time, multiple eddy current sensors inside the detection component can quickly detect the position of the two metal sliders. The height difference between the two metal sliders in the vertical plane is used to calculate whether a leak has occurred. The entire detection component has a simple structure, strong practicality, and high reliability. Attached Figure Description

[0040] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0041] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0042] like Figure 1-9As shown, the present invention proposes an intelligent alarm device for water supply and drainage pipelines, including a control box 1, an inlet pipe 6, and an outlet pipe 7. The control box 1 is provided with a communication mechanism 2 for connecting the inlet pipe 6 and the outlet pipe 7. The control box 1 is also provided with a detection component 3 for detecting pipeline leaks.

[0043] The connecting mechanism 2 includes a flow guiding component 5 disposed at the bottom of the control box 1 and a drive component 4 that drives the flow guiding component 5 to work;

[0044] The flow guiding assembly 5 includes two control cylinders 501 symmetrically fixed at the bottom of the control box 1. A water-stop shell 505 is fixedly provided at the middle of the upper end of the control cylinder 501. An inner limiting ring 502 is fixedly provided on one side of the inside of the control cylinder 501. A bevel is opened on the inner side of one end of the inner limiting ring 502. A baffle plate 503 is slidably provided inside the control cylinder 501. Multiple sliding blocks 5031 are fixedly provided on the outer side of the middle part of the baffle plate 503. A sliding groove for use with the sliding block 5031 is opened on the inner wall of the control cylinder 501 and the middle part of the inner limiting ring 502.

[0045] A drive rod 504 is fixedly installed at the upper middle part of the baffle plate 503. Two water-stop plates 506 are fixedly installed inside the water-stop shell 505. The upper end face of the uppermost water-stop plate 506 contacts the upper part of the inside of the water-stop shell 505, and the lower end face of the lowermost water-stop plate 506 contacts the bottom of the water-stop shell 505.

[0046] An L-shaped hinge seat 507 is fixedly provided at the upper end of the drive rod 504 and outside the water-stop shell 505. The flow guiding assembly 5 also includes connecting rings 508 symmetrically fixed at both ends of the control box 1. The two connecting rings 508 are respectively connected to the interior of the two control cylinders 501.

[0047] The drive assembly 4 includes a bidirectional lead screw 401 rotatably disposed on one side inside the control box 1. A worm gear 402 is fixedly disposed in the middle of the bidirectional lead screw 401. Two threaded seats 403 are also symmetrically disposed in the middle of the bidirectional lead screw 401 via threaded connection. Two limiting sliders 404 are symmetrically slidably disposed on the inner wall of the control box 1. A fixing rod 405 is fixed between the limiting slider 404 and the threaded seat 403 on the same side. A rotating rod 406 is rotatably disposed in the middle of the fixing rod 405. The other end of the rotating rod 406 is hinged to the middle of the L-shaped hinge seat 507.

[0048] The drive assembly 4 also includes a housing 407 fixedly disposed in the middle of the upper part of the control box 1. A worm gear 408 is rotatably disposed inside the housing 407. The worm gear 408 meshes with a worm wheel 402. A drive motor 409 is fixedly disposed at one end of the housing 407. The output end of the drive motor 409 is fixedly connected to one end of the worm gear 408. An operating turntable 410 is fixedly disposed at the other end of the worm gear 408 outside the housing 407.

[0049] As can be seen from the above, when it is necessary to separate the inlet pipe 6 and the outlet pipe 7, manual or electric control can be used. Electric control means that the drive motor 409 works, which in turn drives the worm gear 408 to rotate. The rotation of the worm gear 408 can drive the worm wheel 402 to rotate, which in turn causes the bidirectional lead screw 401 to rotate, which in turn causes the two threaded seats 403 to move in opposite directions. Since the lower end of the threaded seat 403 is fixedly provided with a fixing rod 405, and the middle part of the fixing rod 405 is rotatably provided with a rotating rod 406, the two L-shaped hinge seats 507 are driven to move to both sides. That is, the drive rod 504 drives the baffle plate 503 to move into the inner limit ring 502, so that the baffle plate 503 is slidably set in the middle of the inner limit ring 502. The baffle plate 503 blocks the water flow from the inlet pipe 6, and the baffle plate 503 on the right side blocks the outlet, thus effectively intercepting the flow.

[0050] Furthermore, the detection component 3 includes a connecting pipe 301 fixedly disposed between two control cylinders 501. The connecting pipe 301 is interconnected with the two control cylinders 501. A throttling plate 302 is fixedly disposed inside the connecting pipe 301. A U-shaped throttling element 303 is fixedly disposed in the middle of the upper end of the connecting pipe 301. Two metal sliders 304 are symmetrically slidably disposed inside the U-shaped throttling element 303. The metal sliders 304 are cylindrical in shape. A liquid working medium is filled inside the U-shaped throttling element 303 and located between the two metal sliders 304.

[0051] Two mounting brackets 305 are symmetrically fixed at the upper end of the connecting pipe 301, and multiple eddy current sensors 306 are fixed in the middle of the mounting brackets 305.

[0052] As can be seen from the above, the greater the relative distance between the two metal sliders 304 inside the U-shaped throttling device 303, the faster the flow velocity in the connecting pipe 301, which may lead to leakage. When the maximum displacement exists for a time that meets the set time inside the data processing controller, the data processing controller sends a control signal to the drive motor 409 and the alarm indicator light to cut off the water flow. If there is no leakage, personnel can rotate the operating turntable 410 to reset.

[0053] Furthermore, the control box 1 is also equipped with a data processing controller. The signal output terminals of multiple eddy current sensors 306 are electrically connected to the signal input terminals of the data processing controller, and the signal output terminals of the data processing controller are electrically connected to the signal input terminals of the drive motor 409.

[0054] Furthermore, the middle part of the control cylinder 501 and the water-stop shell 505 is also provided with a rectangular through groove that slides with the drive rod 504, and the length of the water-stop plate 506 is greater than the length of the rectangular through groove.

[0055] Furthermore, the lower end face of the bottom waterstop plate 506 is arc-shaped, and the inner wall of the control box 1 is provided with a limiting strip 101 that slides in conjunction with the limiting slider 404.

[0056] Furthermore, the upper part of the control box 1 is equipped with multiple alarm indicator lights, and the signal output terminal of the data processing controller is electrically connected to the input terminal of the alarm indicator light controller.

[0057] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
