Description

Technical Field

[0001] The present invention relates to the technical field of electromagnetic water meters, and in particular to an electromagnetic water meter detection device. Background Art

[0002] With global freshwater resources becoming increasingly scarce, accurate water consumption measurement and management are becoming increasingly important. As a key water meter, the accuracy, measurement range, reliability, lifespan, functionality, and manufacturing cost of a water meter are crucial to water metering and billing, as well as water control, conservation, and management.

[0003] Currently, electromagnetic water meters based on the electromagnetic Faraday induction principle are becoming the preferred water metering instrument for water supply companies due to their accurate, reliable measurement and long service life. Electromagnetic water meter quality inspection devices are used to perform final quality inspections on the mechanical assembly and circuit welding quality of electromagnetic water meters before the entire meter is glued. Existing electromagnetic water meter quality inspection devices require that the electromagnetic water meter pipe section be filled with water before evaluating the proper function of the circuit in the full pipe state. However, when testing electromagnetic water meters with water in the pipe section without gluing and sealing, the circuitry can easily become damp or even splashed, affecting quality. Summary of the Invention

[0004] The present invention provides an electromagnetic water meter detection device, which can complete the detection of the electromagnetic water meter before the measuring pipe section of the electromagnetic water meter is glued.

[0005] In order to solve the above technical problems, the present invention provides an electromagnetic water meter detection device, comprising:

[0006] A positioning bracket, used for inserting into the measuring pipe section of the electromagnetic water meter;

[0007] A conductive O-ring is tensioned and arranged on the positioning bracket, wherein the conductivity of the conductive O-ring is consistent with the conductivity of tap water;

[0008] When the positioning bracket is inserted into the measuring pipe section, the conductive O-ring contacts the first electrode and the second electrode of the electromagnetic water meter so that the first electrode and the second electrode are electrically connected to the conductive O-ring.

[0009] As a preferred embodiment of the above technical solution, a positioning O-ring is further provided on the positioning bracket.

[0010] As a preferred embodiment of the above technical solution, the positioning O-ring is tensioned on the outer wall of the positioning bracket.

[0011] As a preferred embodiment of the above technical solution, there are multiple positioning O-rings.

[0012] As a preferred embodiment of the above technical solution, a plurality of mounting grooves are provided on the outer wall of the positioning bracket along its length direction, and the positioning O-ring is tensioned and arranged in the mounting grooves.

[0013] As a preferred embodiment of the above technical solution, the positioning bracket includes a first supporting portion and a second supporting portion, and the first supporting portion and the second supporting portion intersect each other perpendicularly so that the cross section of the positioning bracket is in a cross shape.

[0014] As a preferred embodiment of the above technical solution, both sides of the first support portion are provided with accommodating openings extending to the surfaces of both sides of the second support portion. The conductive O-ring is tensioned on the second support portion and the conductive O-ring is opened in the accommodating opening. When the conductive O-ring is tensioned on the second support portion, the conductive O-ring is in a runway shape.

[0015] As a preferred embodiment of the above technical solution, a positioning groove is provided on the second supporting portion, and the conductive O-ring is tensioned and arranged in the positioning groove.

[0016] As a preferred embodiment of the above technical solution, a positioning plate is provided at one end of the positioning bracket, and the positioning plate is perpendicular to the positioning bracket.

[0017] As a preferred embodiment of the above technical solution, a positioning column is provided on the surface of the positioning plate close to the positioning bracket.

[0018] The present invention provides an electromagnetic water meter detection device, which includes a positioning bracket and a conductive O-ring. The conductive O-ring is tensioned on the positioning bracket. When in use, the positioning bracket is inserted into the measuring pipe section of the electromagnetic water meter so that the conductive O-ring contacts the first electrode and the second electrode extending into the measuring pipe section. Since the conductive O-ring contacts the first electrode and the second electrode, the first electrode and the second electrode are in an electrically conductive state. Since the conductivity of the conductive O-ring is consistent with the conductivity of tap water, it can be used to replace the tap water required in the detection process. In the existing detection process, the electromagnetic water meter needs to be glued before tap water can be passed into the measuring pipe section to achieve detection. The electromagnetic water meter detection device provided by the present invention can complete the detection of the electromagnetic water meter before the electromagnetic water meter is glued.

DETAILED DESCRIPTION

[0024] In order to make the purposes, features, and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0025] See also Figures 1 to 3 As shown, an embodiment of the present invention provides an electromagnetic water meter detection device, comprising:

[0026] A positioning bracket 10 is used to be inserted into the measuring pipe section 60 of the electromagnetic water meter;

[0027] A conductive O-ring 20 is tensioned and arranged on the positioning bracket 10. The conductivity of the conductive O-ring 20 is consistent with the conductivity of tap water;

[0028] When the positioning bracket 10 is inserted into the measuring pipe section 60 , the conductive O-ring 20 contacts the first electrode 70 and the second electrode 80 of the electromagnetic water meter so that the first electrode 70 and the second electrode 80 are electrically connected to the conductive O-ring 20 .

[0029] The present embodiment provides an electromagnetic water meter detection device, which includes a positioning bracket 10 and a conductive O-ring 20. The conductive O-ring 20 is tensioned on the positioning bracket 10. When in use, the positioning bracket 10 is inserted into the measuring pipe section 60 of the electromagnetic water meter so that the conductive O-ring 20 contacts the first electrode 70 and the second electrode 80 extending into the measuring pipe section 60. Since the conductive O-ring 20 contacts the first electrode 70 and the second electrode 80, the first electrode 70 and the second electrode 80 are electrically conductive. Since the conductivity of the conductive O-ring 20 is consistent with the conductivity of tap water, it can be used to replace the tap water required in the detection process. In the existing detection process, the electromagnetic water meter needs to be glued before tap water can be passed into the measuring pipe section 60 to achieve detection. The electromagnetic water meter detection device provided in the present embodiment can complete the detection of the electromagnetic water meter before the electromagnetic water meter is glued.

[0030] In a further embodiment of the present invention, a positioning O-ring 30 is further provided on the positioning bracket 10 .

[0031] The positioning O-ring 30 in this embodiment is used to contact and cooperate with the inner wall of the measuring pipe section 60 of the electromagnetic water meter, which can enable the positioning bracket 10 to be coaxially positioned with the measuring pipe section 60, so that the conductive O-ring 20 can be evenly contacted with the first electrode 70 and the second electrode 80.

[0032] In addition, in this embodiment, the positioning bracket 10 is positioned by the positioning O-ring 30, and the positioning is simpler and more convenient.

[0033] In a further embodiment of the present invention, the positioning O-ring 30 is tightened on the outer wall of the positioning bracket 10 .

[0034] Specifically, the positioning O-ring 30 in this embodiment is made of soft elastic material.

[0035] In a further embodiment of the present invention, there are multiple positioning O-rings 30 .

[0036] In this embodiment, a plurality of positioning O-rings 30 are used, which can make the positioning bracket 10 more stable during positioning.

[0037] In this embodiment, there are two positioning O-rings 30 , and there is a distance between the two positioning O-rings 30 .

[0038] In a further embodiment of the present invention, a plurality of mounting grooves 103 are provided on the outer wall of the positioning bracket 10 along its length direction, and the positioning O-rings 30 are tensionedly disposed in the mounting grooves 103 .

[0039] The mounting groove 103 can be used to install and position the positioning O-ring 30 , which can prevent the positioning O-ring 30 from being displaced.

The first support portion 101 and the second support portion 102 are perpendicular to each other so that the cross section of the positioning bracket 10 is in a cross shape.

[0041] In this embodiment, the first support portion 101 and the second support portion 102 cross each other perpendicularly. When the positioning O-ring 30 contacts the inner wall of the measuring tube section 60, only the positioning O-ring 30 located between the first support portion 101 and the second support portion 102 is in contact, which can further improve the accuracy and stability of coaxial positioning.

[0042] In a further embodiment of the present invention, both sides of the first support portion 101 are provided with receiving openings 104 extending to the surfaces of both sides of the second support portion 102. The conductive O-ring 20 is tensioned on the second support portion 102 and the conductive O-ring 20 is opened in the receiving openings 104. When the conductive O-ring 20 is tensioned on the second support portion 102, the conductive O-ring 20 is in a runway shape.

[0043] The conductive O-ring 20 in this embodiment is located in the accommodating opening 104 , and the portions of the conductive O-ring 20 stretched on both sides of the second support portion 102 are in contact with the first electrode 70 and the second electrode 80 , respectively, which can prevent the conductive O-ring 20 from contacting other conductors and affecting the detection accuracy.

[0044] In addition, the conductive O-ring 20 in this embodiment is located in the accommodating opening 104, which can also ensure that the conductive O-ring 20 is in full contact with the first electrode 70 and the second electrode 80. Specifically, it can prevent the conductive O-ring 20 from being displaced when the positioning bracket 10 is inserted into the measuring tube section 60, especially when the conductive O-ring 20 is in contact with the first electrode 70 and the second electrode 80, thereby ensuring that the first electrode 70 and the second electrode 80 are in contact with the outer ends of the conductive O-ring 20.

[0045] In a further embodiment of the present invention, a positioning groove 105 is provided on the second supporting portion 102 , and the conductive O-ring 20 is tensionedly disposed in the positioning groove 105 .

[0046] In a further embodiment of the present invention, a positioning plate 40 is provided at one end of the positioning bracket 10 , and the positioning plate 40 is perpendicular to the positioning bracket 10 .

[0047] The positioning plate 40 in this embodiment contacts the end surface of the flange 90 of the measuring pipe section 60 to play a positioning role.

[0048] In a further embodiment of the present invention, a positioning post 50 is provided on a surface of the positioning plate 40 close to the positioning bracket 10 .

[0049] The positioning column 50 in this embodiment is used to be inserted into the mounting hole 100 on the flange 90 , so as to play a role in installation and positioning when the positioning bracket 10 is inserted into the measuring pipe section 60 .

[0050] In this embodiment, both side surfaces of the first support portion 101 and the second support portion 102 are arc-shaped surfaces, and the arc surfaces on both sides of the first support portion 101 and the second support portion 102 are located on the same circumferential surface.
