Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1 to 3 , in the embodiment of the present invention, an antenna connection structure for water meter signal transmission with high stability includes a housing assembly installed on the water meter main body 1. The housing assembly is installed on the water meter main body 1. The water meter main body 1 is a casting and is similar to the main body structure of the current mechanical water meter casting. Openings with the same axis are provided on both the top and bottom of the water meter main body 1 on a partition plate A that separates the water inlet and outlet in the middle. The housing assembly includes a rotating plate 3, a housing mounting seat 4 and a housing 5. The housing mounting seat 4 is fixedly connected to the opening at the top of the water meter main body 1 by bolts. A rubber ring is provided between the housing mounting seat 4 and the water meter main body 1 and is pressed tightly at the contact position between the two. The housing mounting seat 4 is a cylindrical structure and is integrally formed with a bottom plate at the bottom. The opening at the top of the water meter main body 1 is sealed by the housing mounting seat 4 to facilitate the installation of electronic components in the housing assembly. The outer surface of the housing mounting seat 4 is rotatably connected to the rotating plate 3 through a bearing. The housing 5 is fixedly connected to the rotating plate 3 by screws. An existing intelligent water meter electronic system is installed in the housing assembly.

[0024] A threaded hole is formed on the surface of the position where the rotating plate 3 is rotatably connected to the housing mounting seat 4, and a setscrew 15 is threadedly connected thereto. The head of the setscrew is used to abut against the housing mounting seat 4. During use, rotate the setscrew and adjust the orientation of the antenna structure on the housing 5 according to the installation environment, and then tighten the setscrew.

[0025] The upper surface of the housing 5 is provided with a display hole for installing a display and an antenna hole for installing an antenna structure. The surface of the housing where the antenna hole is located is an inclined surface facing downwards. By moving the antenna to the housing surface, the signal receiving area is increased, the use effect is improved, and the signal stability is increased. The antenna structure includes an antenna fixing bracket 7, a motor 8, a cam 9, an antenna 10, an antenna fixing plate 11, a screw 12, a baffle 13, a positioning slot 14, a spring 27 and a metal gasket 28. The antenna fixing bracket 7 is a stainless steel metal plate. One end of the antenna fixing bracket 7 is inserted into the positioning slot 14 formed on the inner wall of the housing 5, and the other end of the antenna fixing bracket 7 is fixedly connected to the inner wall of the housing by screws. A surface of the antenna fixing bracket 7 facing the antenna hole is provided with an antenna fixing plate 11. An antenna 10 is adhered to an outer side surface of the antenna fixing plate 11 (a wire inlet and outlet hole is provided on the antenna fixing plate 11, and the antenna is connected to the signal transceiver end of the wireless module in the intelligent water meter electronic system through a wire). The antenna fixing plate 11 and the antenna can both be manufactured in an arc shape. Threaded holes are provided at four corner positions on another side surface of the antenna fixing plate 11. Four through holes corresponding to the threaded holes are provided on the antenna fixing bracket 7. The head of the screw 12 passes through the through hole and is threadedly connected to the corresponding threaded hole. At the same time, the tail of the screw 12 is connected with a baffle 13, and a spring 27 is arranged between the baffle 13 and the antenna fixing bracket 7. The diameter of the through hole on the antenna fixing bracket 7 is larger than the diameter of the screw 12. A metal gasket 28 is arranged between the surface of the antenna fixing bracket 7 and the spring. The outer diameter of the metal gasket 28 is larger than the diameter of the through hole. The inner diameter of the metal gasket 28 is larger than the diameter of the screw 12 and at the same time smaller than the diameter of the spring. The function of this gasket is to enable the screw 12 to move in the through hole and also ensure that the diameter of the through hole can be increased as much as possible to improve the moving effect. The antenna fixing bracket 7 is connected to the motor 8 through a motor bracket on a surface facing the antenna fixing plate 11. The output end of the motor 8 faces the antenna fixing plate 11 and is connected to the cam 9. The main body of the cam 9 is a cylindrical structure, and a surface facing the antenna fixing plate 11 is an inclined surface, that is, the end of the cam 9 with the inclined surface contacts the antenna fixing plate 11. When the convex point on the inclined surface of the cam 9 is located at the geometric center point of the antenna fixing plate 11, the antenna fixing bracket 7 is parallel to the antenna fixing plate 11. When the convex point on the inclined surface of the cam 9 is far from the geometric center point of the antenna fixing plate 11, the bolts at the four corners of the antenna fixing plate 11 pull the four corners of the antenna fixing plate 11 under the restoring force of the spring, and the angle of the antenna fixing plate 11 is inclined according to the position of the convex point on the inclined surface of the cam 9 to form a structure for adjusting the antenna angle. During actual use, the motor can be powered to drive the cam to rotate for periodic angle adjustment of the antenna. When the maximum signal is determined, the power supply to the motor is stopped, and a better signal reception effect can be obtained.

[0026] During the actual adjustment process, the screw rod tilts and moves under the action of the spring restoring force and the pulling of the antenna fixing plate 11. Since the through hole is relatively large, there is room for movement. At the same time, applying grease between the metal gasket and the antenna fixing bracket 7 can also promote the relative movement of the gasket.

[0027] That is, the usage method of the antenna connection structure for water meter signal transmission with high stability:

[0028] (1) During installation, manually rotate the outer shell 5 to orient the antenna structure on the water meter towards an open area, and then lock the position of the outer shell 5 with a setscrew.

[0029] (2) Use the current wireless signal detection software to monitor the water meter signal, and control the motor to rotate through the controller. When the detected signal reaches the optimal value, the motor stops rotating.

[0030] The metal gasket is made of stainless steel. On the surface of the metal gasket for contacting the antenna fixing bracket 7, 2 - 3 circles of annular protrusions are formed to reduce the area, and at the same time, a part of the grease can be stored between the annular protrusions to improve the effect of movement.

[0031] Such as Figure 1 and 4 , the remotely controlled valves are centralized in the water meter main body 1 to adapt to the redesigned outer shell assembly, which also includes an internal support 2, an impeller 16, a cover plate 17, a lead screw 18, a valve motor 19, a driving bevel gear 20, an internal thread sleeve 21, a valve plate 22, a guide rod 23, a limit switch 24, a hollow 25, and a power structure installation chamber 26. The main body shape of the internal support 2 is cylindrical and the material is food - grade 304 stainless steel. The upper end of the internal support 2 is fixedly connected to the lower surface of the outer shell mounting seat 4 by screws; a hollow 25 is opened in the middle of the internal support 2. On the outer surface of the internal support 2 above the hollow 25, an annular baffle is formed and pressed on the partition A (a rubber ring is squeezed between the baffle and the partition A). Inside the internal support 2 and at the positions above and below the hollow 25, partition Bs are welded. On the partition B above the hollow, a number of water inlet holes are opened and form an impeller accommodation chamber with the area above the internal support 2. An impeller 16 is arranged in the impeller accommodation chamber, and the rotating shaft of the impeller 16 is fixedly connected to a rotational speed sensor 6. The rotational speed sensor 6 is installed in the installation hole opened in the middle of the outer shell mounting seat 4, and a rubber ring is filled between the rotational speed sensor 6 and the inner wall of the installation hole; on the surface of the internal support 2 corresponding to the upper part of the impeller 16, a water outlet hole is opened. The water surges from below to drive the impeller to rotate, and finally the rotational speed is obtained, and the water consumption is measured in cooperation with the metering system.

[0032] The partition B located below the hollow and a part of the internal support below it form a power structure installation chamber 26. The middle of the partition B in the power structure installation chamber 26 is rotatably connected to the outer surface of the internal thread sleeve 21 through a bearing. Sealing rubber rings are filled between the two ends of the bearing corresponding to the internal thread sleeve 21 and its installation holes; the lower end of the internal thread sleeve 21 and the part located in the power structure installation chamber 26 are fixedly connected to a driven bevel gear, which meshes with a driving bevel gear 20. The driving bevel gear is fixedly installed on the output shaft of the valve motor 19, and the valve motor 19 is fixedly connected to the partition B; one end of the internal thread sleeve 21 located in the hollow area is open and threadedly connected to a lead screw 18. The top of the lead screw 18 is fixedly connected to a valve plate 22, which is used to cover the water inlet hole. The lead screw 18, the internal thread sleeve 21, and the valve plate 22 can all be made of plastic material, so as to avoid the rust problem caused by electrochemical corrosion inside, and at the same time, the water pressure from bottom to top can assist in providing the pressure for pressing.

[0033] A threaded blind hole is opened on the lower surface of the valve plate 22 and threadedly connected to a threaded post formed at one end of a guide rod 23. The guide rod 23 is slidably connected to a sliding hole correspondingly opened on the lower partition B. One end of the guide rod 23 located in the power structure installation chamber 26 is fixedly connected to a toggle rod through a screw. Limit switches 24 are arranged in the up-and-down movement direction of the toggle rod. The limit switches 24 are fixedly connected to the corresponding metal brackets. The maximum positions of the lifting of the valve plate 22 are controlled by the limit switches 24, and the limit control of the valve motor is realized through the existing circuit. This control method and circuit are prior arts and will not be elaborated here.

[0034] In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components.
