Description

Technical Field

[0001] The present invention relates to the technical field of water meter boxes, and particularly to an expandable water meter box. Background Art

[0002] In the civil infrastructure construction of modern cities and rural areas, water meter boxes, as key equipment for maintaining and managing water meters and valves, play a crucial role. Currently, there are various types of water meter boxes on the market, including iron water meter boxes, plastic water meter boxes, and fiberglass water meter boxes, etc. They each have their own characteristics in terms of corrosion resistance, impact resistance, and service life. However, in terms of water meter anti-freezing, due to reasons such as materials and structural design, factors such as non-sealing and ventilation exist, and there are still some deficiencies in the existing water meter box technology.

[0003] Traditional water meter boxes are relatively single in design and function and are difficult to meet the diverse needs of modern water supply systems. For example, it is required that the water meters and valve pipelines in the water meter box be horizontal and vertical, which is necessary for the metering accuracy of the water meters. However, because of the welded pipelines and the uneven levels, it is very difficult to achieve a unified standard. In addition, during the cold wave period, the water meter box lacks heat preservation measures, which easily leads to the freezing and cracking of the water meters and affects the normal water supply.

[0004] Therefore, an expandable water meter box is proposed to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to provide an expandable water meter box to solve the above problems existing in the prior art, prevent the water meters from freezing and cracking, and at the same time make the water meters and valves in the water meter box horizontal and vertical, ensuring performance and being beautiful and generous.

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0017] In order to make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the drawings and specific embodiments.

[0018] Refer to Figure 1-2, the present invention provides an expandable water meter box, comprising:

[0019] A box body 1, a heat preservation layer 2 is filled inside the side wall of the box body 1, a box cover 3 is rotatably connected to the box body 1, a heat preservation layer 2 is filled inside the box cover 3, a first through hole and a plurality of second through holes are opened inside the box body 1, a water inlet joint 4 is fixedly connected inside the first through hole, a water outlet joint 5 is fixedly connected inside the second through hole, a water distributor 6 and a plurality of first water outlet pipes 7 are arranged inside the box body 1, the water distributor 6 is connected to the water inlet joint 4, one end of the water inlet joint 4 far away from the water distributor 6 is connected with a water inlet pipe, one end of the first water outlet pipe 7 is communicated with the water distributor 6, the other end of the first water outlet pipe 7 is communicated with the water outlet joint 5, one end of the water outlet joint 5 far away from the first water outlet pipe 7 is communicated with a second water outlet pipe, a lock valve 8, a water meter 9 and a gate valve 10 are installed on the first water outlet pipe 7, and the water meter 9 is located between the lock valve 8 and the gate valve 10.

[0020] In this device, the heat preservation layer 2 can improve the anti-freezing ability of protecting the box body 1, prevent the water meter 9 from being frozen, the water inlet joint 4 and the water outlet joint 5 are connected with the box body 1 together, which can prevent cold air from entering the box body 1 and improve the heat preservation performance, the water distributor 6 is used for installing a plurality of first water outlet pipes 7, and the water distributor 6 can divide the inlet water into multiple outlet waters.

[0021] As a further optimized solution, the box body 1 comprises an outer shell 11 and an inner shell 12, the heat preservation layer 2 is filled between the outer shell 11 and the inner shell 12, the first through hole and the second through holes are opened on the outer shell 11 and the inner shell 12, and the box cover 3 is rotatably connected to the outer shell 11.

[0022] As a further optimized solution, the heat preservation layer 2 is a rigid polyurethane heat preservation material.

[0023] As a further optimized solution, the box cover 3 and the box body 1 are rotatably connected through a hinge.

[0024] The traditional heat preservation water meter box is a single box body pasted with heat preservation materials, with holes opened on the box body, and the hole diameter is larger than the diameter of the inlet and outlet water pipes to facilitate the passage of the inlet and outlet water pipes. In this way, when the box door is closed and sealed, it is necessary to seal and plug the hole of the inlet and outlet water pipes. In this case, the whole water meter box is in a sealed state. Due to the reasons of the plugging material and the construction plugging technology, the sealing at the hole may not be in place or the plugging material shrinks to cause unsealing, resulting in cold air entering the meter box and failing to achieve the effect of preventing the water meter from freezing.

[0025] It is very difficult to make the inlet and outlet water pipes and the water meter horizontal and vertical during the on-site connection of the traditional water meter box, and the installation efficiency is not high.

[0026] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention.

[0027] The embodiments described above are only descriptions of the preferred embodiments of the present invention, and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present invention shall fall within the protection scope determined by the claims of the present invention.
