Description

Technical Field

[0001] This application relates to the technical field of water meters, and in particular to a water meter glass cover and a water meter head. Background Technology

[0002] Water meters are key devices for measuring water consumption and are widely used in daily life and industrial production. In northern regions, most water meters are installed in meter wells. To cope with the pressure generated by the water accumulated in the well, the meter head uses a copper cover to lock, seal, and fix the meter glass. Usually, the copper cover presses down on the surface and periphery of the meter glass, and the copper cover and the base of the water meter create a recessed groove between the meter glass and the copper cover.

[0003] In environments with water accumulation in the meter well, water stains and dirt easily accumulate in the groove formed by the meter glass and the copper cover. Moreover, the structure of the groove makes it inconvenient to remove dirt from the outside. Over time, this dirt will obstruct the meter glass, making it difficult to read the meter readings and affecting the accuracy and convenience of water meter readings. Utility Model Content

[0004] To improve the accuracy and convenience of meter reading, this application provides a water meter glass cover and a water meter head.

[0005] In a first aspect, this application provides a water meter glass cover, which adopts the following technical solution: A water meter glass cover includes a glass body, the glass body including a central protrusion and an outer edge surrounding the protrusion; The upper surface of the outer edge is lower than the upper surface of the protrusion to form a stepped structure, and the outer edge is used for pressing and fixing the copper cover. The upper surface of the protrusion is configured such that its lowest point is flush with or higher than the upper surface of the copper cover of the water meter.

[0006] By adopting the above technical solution, the upper surface of the protrusion of the glass body is configured to be flush with or higher than the upper surface of the copper cover at the lowest point, avoiding the sunken groove formed between the glass and the copper cover in the traditional structure, thereby reducing the deposition of dirt on the glass surface and improving the accuracy and convenience of reading the watch.

[0007] Optionally, the bottom of the glass body is recessed inward to form an inner groove for inserting a pointer.

[0008] By adopting the above technical solution, the inner groove at the bottom of the glass body provides a space for the pointer, allowing the pointer to extend into the glass body and shortening the distance between the pointer and the external sensor.

[0009] Optionally, the bottom of the glass body is provided with at least one positioning part to restrict the rotation of the glass body after installation.

[0010] By adopting the above technical solution, the glass body cooperates with other structures of the water meter through the positioning part to restrict the rotation of the glass body, thereby improving the stability of the glass body.

[0011] Optionally, the positioning part is a recess or a protrusion.

[0012] Secondly, this application provides a water meter head, which adopts the following technical solution: A water meter head includes a water meter glass cover, a copper cover, a pointer, and a base, as described above. The copper cover is locked to the base, and the copper cover and the base together clamp the outer edge of the glass body. The pointer is opposite to the protrusion. By adopting the above technical solution, the water meter head is clamped by the copper cover and the base to hold the outer edge of the glass body, thus achieving a stable fixation of the glass cover.

[0013] Optionally, a sealing element is provided between the base and the outer edge, and / or between the copper cover and the outer edge.

[0014] Optionally, it also includes an outer casing, which surrounds the copper cover and is detachably connected to the base, and a slag discharge channel is formed between the outer casing, the copper cover, and the base, which communicates from the upper surface of the protrusion to the external environment.

[0015] By adopting the above technical solution, the slag discharge channel formed between the outer casing, the copper cover, and the base can smoothly guide the dirt or water accumulated on the upper surface of the protrusion to the external environment. This reduces the amount of dirt remaining on the glass surface, improves the self-draining capacity of the meter head, thereby reducing the frequency of manual cleaning and lowering maintenance costs.

[0016] Optionally, the outer casing has a sensor that senses the pointer, and the sensor is used to realize the automatic collection and remote transmission of water meter data.

[0017] Optionally, the base is provided with a display screen located below the protrusion, and the outer casing has an observation port for exposing the display screen.

[0018] By adopting the above technical solution, the display screen installed on the base is located below the protrusion, which can protect the display screen from the influence of the external environment, and the visibility of the display screen is achieved through the observation port.

[0019] In summary, this application includes at least one of the following beneficial effects: 1. By setting the protrusions higher than or flush with the upper surface of the copper cover, dirt is less likely to accumulate, improving the user experience of the water meter in waterlogged and dirty environments; 2. When there is an outer casing, the slag discharge channel can help to discharge water and reduce the accumulation of water and dirt on the surface of the glass body. Attached Figure Description

Detailed Implementation

[0022] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0023] Example 1: This application discloses a glass cover for a water meter. (Refer to...) Figure 1 and Figure 2 The water meter glass cover includes a glass body 1, wherein the glass body 1 is pressed tightly by a copper cover 4 during installation.

[0024] Specifically, the glass body 1 includes a central protrusion 101 and an outer edge 102 surrounding the protrusion 101.

[0025] The protrusion 101 is convex upwards and its structure can be hemispherical, frustum, etc. The material can be high-strength glass, plexiglass, etc. In this embodiment, high-strength glass is preferred because it has good transparency and wear resistance.

[0026] The upper surface of the protrusion 101 is configured such that its lowest point is flush with or higher than the upper surface of the copper cover 4 of the water meter, making it less likely for dirt to accumulate on the upper surface of the protrusion 101 in environments such as water accumulation in the meter well. In this embodiment, the protrusion 101 is a frustum-shaped cone with a flat upper surface. In other embodiments, the protrusion 101 is a hemispherical shape that gradually bulges towards the center along the outer periphery, making it easier for dirt to slide off when it falls on the protrusion 101.

[0027] The outer edge 102 surrounds the protrusion 101 and its shape is adapted to the protrusion 101, usually being annular. The lower surface of the outer edge 102 is flush with the lower surface of the protrusion 101, and the upper surface of the outer edge 102 is lower than the upper surface of the protrusion 101 to form a stepped structure. This stepped structure facilitates the copper cover 4 to press and fix the glass body 1.

[0028] The outer edge 102 is made of the same high-strength glass as the protrusion 101. Furthermore, the outer edge 102 and the protrusion 101 are integrally molded to improve the overall strength and sealing of the glass body 1. The combination logic of the outer edge 102 and the protrusion 101 is that the outer edge 102 provides a mounting and fixing point for the glass body 1, while the protrusion 101 makes the water meter reading clearly visible.

[0029] Furthermore, the bottom of the protrusion 101 is recessed inward to form an inner groove 2 for the pointer 5 to insert into. The inner groove 2 is typically circular in shape, and its size is adapted to the size of the pointer 5, allowing the pointer 5 to rotate freely within the inner groove 2. In this embodiment, the depth of the inner groove 2 is less than the thickness of the outer edge 102. By entering the inner groove 2, the distance between the pointer 5 and the external sensor can be shortened, reducing the likelihood of the sensor affecting the sensing of the pointer 5 due to the excessive thickness of the glass body 1.

[0030] Furthermore, at least one positioning part 3 is provided at the bottom of the glass body 1 to restrict the rotation of the glass body 1 after installation. The positioning part 3 can be a recess or a protrusion. If the positioning part 3 is a recess, its shape can be circular, square, etc., and the size and depth of the recess should be determined according to the actual installation requirements, and the water meter has a protrusion for insertion into the recess. If the positioning part 3 is a protrusion, the water meter has a recess for insertion into the protrusion, so as to indicate the installation position of the glass body 1 and make the glass body 1 less prone to rotation after installation, thereby improving the accuracy and stability of the installation of the glass body 1, enabling the glass body 1 to accurately cooperate with other components of the water meter, and improving the overall performance of the water meter.

[0031] The implementation principle of a water meter glass cover in this application embodiment is as follows: by cooperating with the copper cover 4 through the outer edge 102, water impurities are less likely to be deposited between the glass body 1 and the copper cover 4, thereby improving the accuracy and stability of the reading.

[0032] Example 2: This application discloses a water meter head. (Refer to...) Figure 3 and Figure 4The system includes a water meter glass cover, a copper cover 4, a pointer 5, a base 6, and an outer casing 8. The copper cover 4 is threaded onto the base 6 to lock it in place, and the copper cover 4 and the base 6 together clamp the outer edge 102 of the glass body 1. The outer casing 8 is fitted around the copper cover 4 and is detachably connected to the base 6. The pointer 5 is located in the base 6 and is opposite to the protrusion 101.

[0033] Reference Figure 1 and Figure 2 Specifically, the water meter glass cover is the same as that in Embodiment 1, having a protrusion 101, an outer edge 102, an inner groove 2, and a positioning part 3. In this embodiment, the protrusion 101 is frustum-shaped, and the positioning part 3 is a concave hole.

[0034] Reference Figure 4 and Figure 5 The copper cover 4 is typically made of copper, which has good corrosion resistance and strength. The copper cover 4 is a round cap with its opening facing downwards, and the top of the copper cover 4 has a relief opening 12 that runs through the copper cover 4. The inner diameter of the copper cover 4 is slightly larger than the outer diameter of the outer edge 102, and the size of the relief opening 12 of the copper cover 4 is adapted to the size of the protruding part of the protrusion 101 relative to the outer edge 102.

[0035] The base 6 is the basic component of the water meter head, usually made of plastic or metal, possessing a certain strength and stability. The base 6 has a support portion 13 for supporting the bottom of the outer edge 102, the support portion 13 being annular and adapted to the outer edge 102. The base 6 also has a protruding post 14 that cooperates with the positioning portion 3 of the glass body 1, and the protruding post 14 has a tapered structure with its cross-sectional dimensions gradually decreasing upwards. The pointer 5, as the output display component of the water meter movement, is installed in the base 6. In this embodiment, there are two positioning portions 3, each protruding and corresponding to a positioning portion 3. Furthermore, a display screen 10 is installed in the base 6 to display the water meter reading.

[0036] The outer casing 8 is made of plastic and has a cavity for housing the copper cover 4. The top of the outer casing 8 also has an observation port 11 communicating with the cavity. A sensor (not shown in the figure) for sensing the pointer 5 is installed inside the outer casing 8. The sensor can monitor the rotation of the pointer 5 in real time and transmit the data to external devices, facilitating remote monitoring and management of the water meter. The sensor and pointer 5 sensing interaction is a conventional method and will not be described in detail here.

[0037] Reference Figure 3 and Figure 4During the assembly of the water meter head, the glass body 1 is coaxially placed on the base 6, so that the protrusion 14 abuts into the corresponding positioning part 3, the support part 13 is coaxially supported on the bottom of the outer edge part 102, and the pointer 5 enters the inner groove 2. The display screen 10 is located below the protrusion 101. Then, the copper cover 4 is coaxially threaded onto the base 6, so that the copper cover 4 coaxially surrounds the support part 13 and the outer edge part 102, and the copper cover 4 and the support part 13 together clamp the outer edge part 102 to realize the installation of the glass body 1; at the same time, the protrusion 101 abuts into the relief opening 12, the outer peripheral surface of the protrusion 101 abuts against the inner peripheral surface of the copper cover 4 at the relief opening 12, and the upper surface of the protrusion 101 is flush with the upper surface of the copper cover 4. Then, the outer casing 8 covers the copper cover 4 through the cover cavity and is detachably connected to the base 6 by bolts, so that the part of the outer casing 8 with the sensor is attached to the upper surface of the protrusion 101 and located directly above the inner groove 2, so that the sensor in the outer casing 8 can properly sense the pointer 5; at the same time, the observation port 11 on the outer casing 8 is opposite to the display screen 10.

[0038] Reference Figure 4 and Figure 6 Furthermore, in this embodiment, a gasket 15 is placed between the copper cover 4 and the upper surface of the outer edge 102 of the glass body 1, and a sealing element 7 is provided between the support part 13 and the lower surface of the outer edge 102. The sealing element 7 can be a rubber sealing ring. In other embodiments, the sealing element 7 may be provided only between the copper cover 4 and the upper surface of the outer edge 102, or only between the support part 13 and the lower surface of the outer edge 102.

[0039] Reference Figure 3 and Figure 6 Furthermore, a slag discharge channel 9 is formed between the outer casing 8, the copper cover 4, and the base 6, connecting the upper surface of the protrusion 101 to the external environment. The direction of slag discharge is indicated by a red arrow in the figure. The slag discharge channel 9 allows accumulated water and dirt between the protrusion 101 and the outer casing 8 to leave the protrusion 101 through the slag discharge channel 9 and be discharged into the external environment. Moreover, since the outer casing 8 and the base 6 can be quickly disassembled and assembled using bolts, even if there is dirt on the glass body 1, the operator can quickly remove the outer casing 8 for cleaning.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
