Description

Technical Field

[0001] The utility model relates to the technical field of direct-through water tanks, and particularly relates to an expandable circulating direct-through water tank. Background Technique

[0002] Water tanks are usually used to store heated hot water to meet the hot water needs of daily life or commercial use. The water tank on a solar energy device is a device for storing solar thermal energy. It is usually used together with a solar hot water system to collect and store solar hot water. When the solar hot water system receives sunlight, the solar collector converts solar energy into heat energy and then transfers the heat energy to the water in the water tank. The water tank stores the heat energy for daily use. Using solar energy can reduce the dependence on traditional energy sources, reduce energy costs, and reduce the impact on the environment. They are a sustainable and environmentally friendly option that can help us make more effective use of solar energy resources.

[0003] Solar energy usually includes a water tank, a mounting bracket, vacuum heat pipes, etc. The internal structure of the water tank can vary according to specific designs and models, but usually includes a water tank body, an upper and lower water channel, a water pipe connection port, a temperature sensor, and a controller, etc. Each component cooperates with each other to meet the usage requirements of daily life or commercial use.

[0004] In view of the above related technologies, the existing water tank realizes water inlet and outlet by connecting double direct-through pipes. However, the double direct-through pipes may bend after long-term use, thereby slowing down the water flow rate and affecting the use of solar energy. Therefore, for the improvement of the existing direct-through water tank, it is particularly important to design a new type of expandable circulating direct-through water tank to solve the above technical defects and improve the practicability of the overall direct-through water tank. Content of the Utility Model

[0005] The purpose of the present utility model is to provide an expandable circulating direct-through water tank. The double direct-through pipes of the water tank body can achieve water inlet and outlet into the inner tank. When the upper and lower water channels are energized, water heating can be realized. A support frame is arranged inside the water tank body to support the double direct-through pipes, reducing the possibility of the double direct-through pipes bending. The smooth pipe has no threads and no corrugations, thus avoiding the influence of metal fatigue caused by the vibration of the heat exchange channel on the water flow velocity, increasing the stability and safety of the equipment. Two double direct-through pipes are provided, one for water inlet and the other for water outlet, thereby reducing the possibility of air resistance in the pipeline. The double-tube heat exchange is more stable than the single-tube heat exchange system and the equipment is not easily damaged. Multiple water tank bodies can be connected and the maintenance cost can be reduced; the positions of the inlet and outlet pipes not only do not affect the occupation of the space of the vacuum tubes, especially the heat pipes, inside the water tank body, but also can realize the continuous heat exchange function in the low water level state; the inlet water pipe is at the bottom and the outlet water pipe is at the top, making the heat exchange effect form a convective heat exchange with the water temperature stratification inside the water tank body, increasing the heat exchange effect, so as to solve the problems raised in the above background technology.

The moving block is rotatably connected to one end of the connection block extending outside the limit ring. The pulling rope is located outside the moving block.

[0024] Next, in combination with the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model. Embodiment

[0025] Please refer to Figures 1-5 , the present utility model provides a technical solution:

[0026] An expandable circulating straight-through water tank, including a water tank main body 1, an inner tank 2 is provided inside the water tank main body 1, and a water inlet and outlet channel 3 is provided inside the water tank main body 1. Below the water inlet and outlet channel 3 and inside the water tank main body 1, two groups of double straight-through pipes 4 are provided, and two groups of support frames 5 are provided outside the two groups of double straight-through pipes 4.

[0027] Furthermore, connection components 6 are provided at both ends of the support frame 5 close to the two groups of double straight-through pipes 4, and multiple support pieces 7 are provided inside the support frame 5. There is a cavity among several support pieces 7, which can play a certain buffering effect and can generate a certain deformation when stressed, thereby reducing the possibility of deformation of the double straight-through pipe 4.

[0028] Among them, the multiple support pieces 7 are designed in a rectangular structure, and the multiple support pieces 7 are evenly distributed inside the support frame 5. The support frame 5 is designed in an arc structure, and the support frame 5 is made of aluminum alloy material as a whole. Using aluminum alloy material for support can not only provide a good support effect but also ensure a good heat transfer effect.

[0029] Secondly, the positions of the two groups of double straight-through pipes 4 inside the water tank main body 1 are such that one is located on the left side of the horizontal center line of the water tank main body 1, and the other double straight-through pipe 4 is located on the lower right side of the vertical center line of the water tank main body 1. There are two double straight-through pipes 4 in the water tank. One of the two double straight-through pipes 4 can be used for water inlet, and the other can be used for water outlet, thereby reducing the possibility of air resistance in the pipeline. The double-pipe heat exchange is more stable than the single-pipe heat exchange system and the equipment is not easily damaged. It can realize the connection of multiple water tank main bodies 1 and can reduce the maintenance cost.

[0030] Furthermore, the material of the double straight-through pipe 4 is stainless steel 304, and the surface of the double straight-through pipe 4 is a smooth straight pipe without threaded corrugations. A one-way breathing valve 8 is provided at the top of the water tank main body 1, and a windproof ring 9 is provided outside the one-way breathing valve 8. The function of the one-way breathing valve 8 is to balance the air pressure inside and outside the water tank main body 1, prevent the water tank main body 1 from generating excessive negative pressure or positive pressure due to the air pressure difference, thereby protecting the structural safety of the water tank main body 1 and ensuring the normal flow of water inside the water tank main body 1. The function of the windproof ring 9 is to protect the one-way breathing valve 8 and prevent external air or pollutants from entering the inside of the one-way breathing valve 8. It is usually installed at the outlet of the one-way breathing valve 8 to prevent dust, particulate matter or other pollutants from entering the valve, thereby avoiding affecting the normal operation of the valve.

[0031] Furthermore, the connecting component 6 is composed of a limit ring 10, a limit block 11, a connecting block 12, a moving block 13, a pull rope 14, and a fixing block 15. The limit ring 10 is located outside the support frame 5, the limit block 11 is slidably connected to the inside of the limit ring 10, the connecting block 12 is located inside the limit ring 10, the moving block 13 is rotatably connected to one end of the connecting block 12 extending outside the limit ring 10, the pull rope 14 is located outside the moving block 13, and the fixing block 15 is located outside the limit block 11 and inside the limit ring 10. When the double straight-through pipe 4 is connected to the support frame 5, the double straight-through pipe 4 can be quickly connected to the support frame 5 through the connecting component 6.

[0032] Furthermore, the connecting block 12 is designed in an arc structure. One end of the pull rope 14 far from the moving block 13 is connected to the fixing block 15. A compression spring 16 is provided outside the fixing block 15 and outside the limit block 11, and the fixing block 15 is slidably connected to the limit ring 10. Connect the double straight-through pipe 4 to the limit ring 10 so that it can be connected to the connecting block 12, fit the surface of the connecting block 12, drive the connecting block 12 to displace, cause the moving block 13 to displace, pull the pull rope 14 to displace, cause the fixing block 15 to displace, drive the limit block 11 to displace, and displace the limit block 11 to the end of the limit ring 10 far from the fixing block 15, so that the double straight-through pipe 4 can be limited inside the limit ring 10, thereby enabling the double straight-through pipe 4 to be installed outside the support frame 5.

[0033] In this embodiment, the implementation scenario is specifically as follows: During actual use, the double straight-through pipe 4 is connected to the limit ring 10 so that it can be connected to the connection block 12, fit the surface of the connection block 12, drive the connection block 12 to displace, cause the moving block 13 to displace, pull the pull rope 14 to displace, cause the fixed block 15 to displace, drive the limit block 11 to displace, and displace the limit block 11 to the end of the limit ring 10 away from the fixed block 15, so that the double straight-through pipe 4 can be limited inside the limit ring 10, thereby enabling the double straight-through pipe 4 to be installed outside the support frame 5. There is a cavity among several support pieces 7, which can play a certain buffering effect and can deform to a certain extent when stressed, thereby reducing the possibility of deformation of the double straight-through pipe 4. One of the two double straight-through pipes 4 can be used for water inlet and the other for water outlet, thus reducing the possibility of air resistance in the pipeline. The double-tube heat exchange is more stable than the single-tube heat exchange system and the equipment is not easily damaged. It can connect multiple water tank bodies 1 and can reduce the maintenance cost. The function of the one-way breathing valve 8 is to balance the air pressure inside and outside the water tank body 1, prevent the water tank body 1 from generating excessive negative pressure or positive pressure due to the air pressure difference, thereby protecting the structural safety of the water tank body 1 and ensuring the normal flow of water in the water tank body 1. The function of the wind shield 9 is to protect the one-way breathing valve 8 and prevent external air or pollutants from entering the one-way breathing valve 8. It is usually installed at the outlet of the one-way breathing valve 8 to prevent dust, particulate matter or other pollutants from entering the valve, thereby avoiding affecting the normal operation of the valve. Compared with the existing straight-through water tank, the overall practicality of the straight-through water tank can be improved by the design of the present utility model.
