Description

Technical Field

[0001] This utility model relates to the field of water meter box technology, specifically to an antifreeze and heat-insulating water meter box. Background Technology

[0002] A water meter box is a housing device used to install, protect, and manage water meters and related equipment. Water meters can be installed inside the box to accurately measure the water consumption of households, businesses, or other places, providing a basis for water bill calculation. It can also protect water meters from external impacts, vibrations, corrosion, and other factors.

[0003] A search revealed that Chinese patent application CN202420649688.5 discloses an antifreeze and heat-insulating water meter box, comprising a box body. Several water valves are symmetrically arranged on the upper and lower sides of the box body. An inlet pipe and an outlet pipe are fixed to opposite sides of each water valve. A power supply unit is fixedly connected to the center of the top of the box body. The power supply unit has electrical terminals on its left, right, and bottom sides, each with wiring. The wiring at the bottom of the power supply unit extends downwards into the box body, and a warm light lamp is fixedly connected to its end. A heat-conducting layer is attached to the outside of each inlet pipe, and a heating cylinder is installed on the outside of the heat-conducting layer. This prior art primarily uses a power supply unit mounted on the top of the box body, combined with warm light lamps, to heat the inside of the box. Then, a heating cylinder is used to provide constant-temperature heating to the inlet pipe, ensuring smooth water flow inside the water meter box and at its external inlet, thus improving its antifreeze strength in cold weather.

[0004] The aforementioned existing technology mainly utilizes a warm light lamp in conjunction with a heating cylinder to heat the liquid entering the upper inlet pipe. The flow of the heated liquid allows the heat-conducting layer to absorb and conduct heat, thereby raising and maintaining the temperature inside the water meter box. This improves the antifreeze effect on the electronic components inside the water meter box in extremely cold temperatures. While this antifreeze method can provide some protection, the heating temperature of the warm light lamp is relatively low. As the heated liquid continues to flow, the heat dissipates rapidly at the outlet, making it prone to freezing in extremely cold temperatures. This ice blockage at the outlet prevents further liquid flow and affects subsequent use. Utility Model Content

[0005] The purpose of this utility model is to provide a freeze-proof and heat-insulating water meter box, which solves the problem that in the existing water meter box, the heating effect of the warm light lamp on the liquid is poor, and the temperature dissipates quickly as the liquid flows, causing the liquid at the outlet to freeze easily.

[0006] This utility model provides the following technical solution: a freeze-proof and heat-insulating water meter box, including a box body, a cabinet door at one end of the box body, a protective component at the outer end of the box body, and the protective component including a shell fitted on the outer end of the box body, a liquid inlet fixedly connected to the upper end of the shell, and a liquid outlet fixedly connected to the lower end of the shell, a sealing component at the outer end of the liquid inlet and the liquid outlet, and a heat-insulating component on the inner side of the shell, which can improve the protective effect of the shell and the box body, a heating component on the inner side of both ends of the box body, which can heat the added liquid, and one end of the cabinet door is rotatably connected to the shell.

[0007] The above technical solution allows for the storage of liquids within the space formed by the outer shell and the container, enabling subsequent heating and use.

[0008] As a preferred embodiment of the above technical solution, a pressure valve is fixedly connected to the upper side of one end of the outer shell, and a groove is provided at the lower end of the pressure valve.

[0009] As a preferred embodiment of the above technical solution, the sealing assembly includes a cover plate with threaded engagement between the outer ends of the liquid inlet and the liquid outlet, and a connecting rod is fixedly connected to the inner side of the cover plate, with a sealing plug fixedly connected to the end of the connecting rod away from the cover plate.

[0010] The above technical solution improves the sealing effect by sealing the inside of the inlet and outlet with a sealing plug.

[0011] As a preferred embodiment of the above technical solution, the heat insulation component includes a heat insulation plate fixedly connected to the inner side of the outer shell, and the heat insulation plate and the outer side of the box are fixedly connected with corrosion-resistant paint.

[0012] The above technical solutions improve the insulation effect by using heat insulation boards and enhance the protective effect by using corrosion-resistant paint.

[0013] As a preferred embodiment of the above technical solution, the corrosion-resistant paint is applied to the insulation board and the housing using a spraying process.

[0014] As a preferred embodiment of the above technical solution, the heating assembly includes a power supply fixedly connected to the inner sides of both ends of the housing, and a heating plate electrically connected to one end of the power supply, the heating plate being fixedly connected to the outer side of the housing.

[0015] The above technical solution utilizes a heating plate to heat the liquid.

[0016] As a preferred embodiment of the above technical solution, the outer shell and the lower end of the box are fixedly connected by a connecting column, and a sealed space is formed between the outer shell and the box.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This type of antifreeze and heat-insulating water meter box can improve the heating effect of liquids through the combination of protective components and sealing components, thereby improving the antifreeze and heat-insulating effects and preventing the outlet from freezing and blocking due to rapid heat dissipation caused by water flow.

Detailed Implementation

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] like Figures 1-4 As shown, this utility model provides a technical solution: a freeze-proof and heat-insulating water meter box, including a box body 1, a cabinet door 11 at one end of the box body 1, a protective component 2 at the outer end of the box body 1, and the protective component 2 including an outer shell 21 fitted on the outer end of the box body 1, an inlet 22 fixedly connected to the upper end of the outer shell 21, and an outlet 23 fixedly connected to the lower end of the outer shell 21, a sealing component 3 at the outer ends of the inlet 22 and the outlet 23, and a heat-insulating component 4 on the inner side of the outer shell 21, which can improve the protective effect of the outer shell 21 and the box body 1. A heating component 5 is provided on the inner side of both ends of the box body 1, which can heat the added liquid, and one end of the cabinet door 11 is rotatably connected to the outer shell 21. Through the cooperation of the protective component 2 and the sealing component 3, the heating effect of the liquid can be improved, thereby improving the freeze-proof and heat-insulating effect, and avoiding the situation where the heat is dissipated too quickly due to the flow of water, resulting in freezing and blockage at the outlet.

[0026] like Figure 2 As shown, a pressure valve 24 is fixedly connected to the upper side of one end of the outer casing 21, and a slot is provided at the lower end of the pressure valve 24.

[0027] like Figure 2 As shown, the sealing assembly 3 includes a cover plate 31 with threaded engagement between the outer ends of the liquid inlet 22 and the liquid outlet 23. A connecting rod 32 is fixedly connected to the inner side of the cover plate 31. A sealing plug 33 is fixedly connected to the end of the connecting rod 32 away from the cover plate 31. The connecting rod 32 and the sealing plug 33 can be installed on the outer side of the liquid inlet 22 and the liquid outlet 23 through the cover plate 31. At the same time, the cover plate 31 and the sealing plug 33 are used to seal and insulate the liquid inlet 22 and the liquid outlet 23.

[0028] like Figure 4 As shown, the insulation component 4 includes a heat insulation plate 41 fixedly connected to the inner side of the outer shell 21, and a corrosion-resistant paint 42 fixedly connected to the outer side of the heat insulation plate 41 and the outer side of the box 1, thereby improving the heat insulation and protection effect.

[0029] like Figure 4 As shown, corrosion-resistant paint 42 is applied to the insulation board 41 and the housing 1 using a spraying process.

[0030] like Figure 2 As shown, the heating assembly 5 includes a power supply 51 fixedly connected to the inner sides of both ends of the housing 1, and a heating plate 52 electrically connected to one end of the power supply 51. The heating plate 52 is fixedly connected to the outer side of the housing 1. The power supply 51 controls the operation of the heating plate 52 to generate heat, thereby using the heat generated by the heating plate 52 to heat the liquid.

[0031] like Figure 2 As shown, the outer shell 21 is fixedly connected to the lower end of the box 1 by a connecting column, and a sealed space is formed between the outer shell 21 and the box 1. The liquid is stored in the space formed between the outer shell 21 and the box 1 for subsequent heating.

[0032] Working principle: When the water meter box is in use, liquid can be injected into the tank body 1 and the outer shell 21 through the liquid inlet 22 for storage. Then, the cover plate 31, along with the connecting rod 32 and the sealing plug 33, is inserted into the liquid inlet 22. The cover plate 31 is then screwed onto the outside of the liquid inlet 22 for installation. Subsequently, the heating plate 52 is controlled by the power supply 51 to operate. After the heating plate 52 operates, it generates heat to heat the liquid in the tank body 1 and the outer shell 21. The heated liquid heats the electronic components inside the tank body 1, thereby preventing the intrusion of external cold air. Later, the liquid in the tank body 1 and the outer shell 21 can be replaced by screwing on the cover plate 31 on the outside of the liquid outlet 23. At the same time, the heat insulation effect is improved by the heat insulation plate 41 and the corrosion-resistant paint 42 during use. When the liquid in the tank body 1 and the outer shell 21 is heated and generates high pressure, the high pressure is discharged through the pressure valve 24 to release the pressure.

[0033] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
