Description

Technical Field

[0001] This utility model relates to the field of composite lightweight water meter boxes with high protection, specifically a composite lightweight water meter box with high protection. Background Technology

[0002] In water supply systems, water meter boxes play a crucial role in protecting metering equipment such as water meters and facilitating meter reading and maintenance. Traditional water meter boxes are often made of a single material, such as ordinary plastic water meter boxes, which have several shortcomings in terms of protective performance. For example, they have poor impact resistance and are easily damaged by external impacts, exposing internal components such as the water meter. This not only shortens the lifespan of the water meter but may also affect normal water supply metering functions due to water ingress. Considering the potential problems mentioned above, it is necessary to design water meter box products with better structural strength.

[0003] For example, a steel fiber reinforced water meter box disclosed in Chinese utility model patent application CN201721099350.3 includes a box body with a cover plate on the top. The box body is made of composite plastic material, and the side wall of the box body has a mesh plate. The bottom of the box body extends outward with a stepped mounting plate. The two ends of the box body have U-shaped pipe grooves. One end of the cover plate is movably hinged to one end of the box body, and the other end of the cover plate has a locking assembly. The inner side wall of the other end of the box body has a lock hole that cooperates with the locking assembly. The locking assembly includes an outer fixing plate, an inner fixing plate, and a pin. The outer fixing plate and the inner fixing plate are fixed to the bottom of the same end of the cover plate. One end of the pin has a lever, and the top of the lever passes through the lever groove on the cover plate to form a lever position. The other end of the pin passes through the inner fixing plate and the outer fixing plate in sequence and cooperates with the lock hole.

[0004] However, the applicant discovered that while water meter boxes like those described in the above proposal possess sufficient structural strength to resist external impacts, significant temperature differences between day and night are common in certain outdoor working environments. This is especially true in remote mountainous areas, plateau regions, or large outdoor industrial sites, where daytime temperatures are high due to direct sunlight, while nighttime temperatures drop sharply. These drastic temperature variations can adversely affect the water meter box and its internal components, such as the water meter itself. Traditional water meter boxes often fail to adequately consider these complex temperature environments, leading to problems such as deformation and cracking of the box material due to thermal expansion and contraction, reduced waterproofing and dustproofing performance, and decreased accuracy and damage to internal water meter components due to thermal stress caused by temperature changes. These issues ultimately affect normal water supply measurement and the lifespan of the equipment.

[0005] To address the aforementioned issues, this invention provides a highly protective composite lightweight water meter box that significantly reduces the heat exchange efficiency between the inner and outer sides of the box, allowing the water meter device to operate under a relatively constant temperature. This prevents detection errors or damage to more precise or multifunctional water meter products when operating in harsh environments. Utility Model Content

[0023] The following specific embodiments are merely explanations of this utility model and are not intended to limit it. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this utility model.

[0024] This solution is achieved through the following technical means:

[0025] Example: In this example, a composite lightweight water meter box with high protection is provided, which can significantly reduce the heat exchange efficiency between the inside and outside of the box, allowing the water meter device to work under a relatively constant temperature, and avoiding detection errors or damage to more precise or multifunctional water meter products when working in harsh environments.

[0026] For details, please refer to the instruction manual appendix. Figure 1The structural layout shown indicates that the water meter box device includes a water meter box body 1, which is hollow and forms a receiving cavity 101 for installing and fixing the water meter. A movable, openable door 102 is installed on the front side of the water meter box body 1. An insulation layer structure 2 is provided inside the plates surrounding the water meter box body 1 to reduce the heat exchange efficiency between the receiving cavity 101 and the outside environment. A guide rail connection structure 3 connects the movable, openable door 102 to the main box body, enabling the door to move back and forth horizontally and control the opening or closing of the water meter box. An opening for pipes to pass through is also provided on the water meter box body 1. To prevent heat exchange between the inside and outside of the water meter box at this opening, and to prevent external impurities and moisture from entering the interior of the water meter box, an insulation covering layer 4 is filled in the opening and covers the outside of the pipes. For example, the insulation covering layer 4 can be made of polyurethane foam or polystyrene foam.

[0027] The most significant technical improvement of this application compared to existing water meter box products lies in the design of a heat insulation layer structure 2 within the plate used to surround and form the water meter box body 1. Specifically, the concrete implementation of this heat insulation layer structure 2 can be found in the appendix to the specification. Figure 2 The structure is illustrated in the schematic diagram shown. First, the structure includes a hollow mounting layer 201 disposed inside the plate of the water meter box 1 and a heat insulation material layer 202 disposed inside the hollow mounting layer 201. A gap barrier space 203 is provided between the surface of the heat insulation material layer 202 and the inner surface of the hollow mounting layer 201.

[0028] Included in the instruction manual Figure 2 Taking the structure shown as an example, when connecting and setting up this structure, it is necessary to first open recessed, elongated mounting grooves 204 on both sides near the middle position of the hollow mounting layer 201 inside the single plate. Then, an aerogel insulation cotton material that can serve as a heat insulation layer 202 is embedded into the mounting grooves 204 on both sides, thereby achieving a preliminary connection and fixation between the heat insulation layer 202 and the internal space of the hollow mounting layer 201. At the same time, in this structure, the aerogel insulation cotton material serving as the heat insulation layer 202 divides the hollow mounting layer 201 into two independent gap barrier spaces 203.

[0029] It's important to note that aerogel insulation material was chosen because it's a highly efficient thermal insulation material composed of nano-aerogel and fiber materials. Its porous internal structure gives it an extremely low thermal conductivity (0.013 - 0.025 W / (m·K)), resulting in excellent insulation performance. It's widely used in high-temperature pipelines and cryogenic storage tanks. Its high porosity (80% - 99.8%) and low density make it lightweight, while also possessing good flexibility and tensile strength, facilitating processing and installation. It exhibits excellent high-temperature resistance, capable of withstanding extremely high external temperatures. Furthermore, its strong hydrophobicity and corrosion resistance ensure stability and reliability in humid and corrosive environments, making it a comprehensive insulation material. When aerogel insulation cotton is used as the aforementioned insulation material layer 202, on the one hand, the material layer itself can play a good heat blocking effect. On the other hand, since the insulation material layer 202 divides the hollow mounting layer 201 into two independent spaces, the heat will repeatedly collide and reflect between the surface of the insulation material layer 202 and the inner wall of the hollow mounting layer 201 during the heat transfer process through the gap barrier space 203 by radiation. This forms a separate constant temperature zone inside each independent gap barrier space 203 and further blocks the heat from passing through this zone space to the inside and outside of the water meter box.

[0030] Therefore, this structural design can greatly reduce the heat exchange efficiency between the inside and outside of the water meter box, ensuring that the water meter inside the box can maintain a stable operating temperature environment even when used in an environment with a large temperature difference between day and night, thereby achieving more accurate data recording and reading.

[0031] Furthermore, the inventors considered that due to the low strength of the internal material structure of aerogel insulation cotton, if the aforementioned structural layout is used, the aerogel insulation cotton material serving as the insulation layer 202 is prone to collapse in the middle and at the point where it contacts the box surface after a period of use, thereby damaging the aforementioned space and reducing the heat insulation effect. Considering this actual situation, a further preferred structural solution is adopted in the embodiments of this application, in which several supporting connecting columns 205 are provided between the inner wall of the hollow mounting layer 201 and the insulation material layer 202. For example, these supporting connecting columns 205 can be made of ceramic material, ensuring sufficient structural strength while also achieving a good heat insulation effect through their porous structure.

[0032] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
