Description

Technical Field

[0001] This utility model relates to the technical field of water tank supply equipment, and in particular to an automatic ventilation device for water tanks. Background Technology

[0002] The mainstream existing urban secondary water supply system adopts the secondary water supply method of water tank. This method involves installing water storage tanks in the areas to be supplied with water, and using tap water provided by the municipal water supply network to fill the water storage tanks. The water in the storage tanks can make up for the insufficient water consumption during peak hours.

[0003] However, municipal tap water generally contains a certain amount of dissolved chlorine. During the process of replenishing water to the water tank through the municipal pipe, the dissolved chlorine will continuously evaporate. If the ventilation opening at the top of the water tank is insufficient to remove the evaporated chlorine, it will easily lead to the continuous accumulation of chlorine in the waterless cavity at the top of the water tank, thereby accelerating the corrosion of the water tank and greatly reducing its service life. Therefore, improvements are urgently needed. Utility Model Content

[0004] The main purpose of this invention is to propose an automatic ventilation device for water tanks, which solves the problem of reduced service life of water tanks in secondary water supply systems due to the inability of chlorine to evaporate in a timely manner.

[0005] To achieve the above objectives, this utility model proposes an automatic ventilation device for a water tank. The device includes: a ventilation duct, one end of which is connected to the water tank body, and the other end of which is connected to the external environment; an installation section with an inlet and an outlet, the inlet and outlet being coaxially arranged and located on opposite sides of the installation section; an exhaust fan installed within the installation section, the fan's rotation axis extending parallel to the extension direction of the installation section; a water inlet pipe, one end of which is connected to a municipal water supply pipe, and the other end of which is connected to the inlet; and a water outlet pipe, one end of which is connected to the outlet, and the other end of which is connected to the water tank. Water enters through the inlet pipe, flows into the outlet via the water pressure-driven exhaust fan, and then flows through the outlet pipe into the water tank.

[0006] In some embodiments, the exhaust fan includes a drive water wheel and a fan impeller. The drive water wheel is rotatably mounted in the mounting section and is located between the water inlet and the water outlet. The fan impeller and the drive water wheel are detachably connected.

[0007] In some embodiments, the mounting section is provided with a fixing frame, the fixing frame including a plurality of brackets extending radially along the mounting section, the brackets being provided with a fixing shaft at the axis of the mounting section, and the drive water wheel being rotatably mounted on the fixing shaft.

[0008] In some embodiments, the outer diameter of the fan impeller is clearance-fitted with the inner diameter of the mounting section.

[0009] In some embodiments, the impeller has a plurality of spaced through holes in its middle portion, and the drive turbine has a threaded hole corresponding to each of the through holes in its middle portion.

[0010] In some embodiments, one end of the water inlet pipe extends from the water inlet into the mounting section, and the end of the water inlet pipe extending into the mounting section is located adjacent to the drive water turbine.

[0011] In some embodiments, the inlet pipe is located on one side of the rotation center of the drive water wheel, so that the water flowing through the drive water wheel impacts the wheel plate of the drive water wheel.

[0012] In some embodiments, one end of the water outlet pipe extends from the water outlet into the installation section, and the end of the water outlet pipe extending into the installation section is provided with a water receiving part.

[0013] In some embodiments, both the drive turbine and the fan impeller are made of aluminum alloy.

[0014] This utility model also provides a water tank supply system, which includes a water tank body, an inlet pipe, a supply pipe, and an automatic ventilation device for the water tank as described above. One end of the inlet pipe is connected to the municipal water supply pipe, and the water tank body is also connected to the supply pipe to supply water to each household. The other end of the inlet pipe is connected to the water tank body, and one end of the ventilation pipe is connected to the top of the water tank body, while the other end of the ventilation pipe is connected to the external environment.

[0015] The beneficial effects of this utility model's technical solution are as follows:

[0016] This utility model's automatic water tank ventilation device connects to the water tank via a ventilation duct, and an exhaust fan is installed inside the duct. The exhaust fan is driven by the water pressure from the municipal water supply inlet pipe, and an outlet pipe supplies the water used to drive the exhaust fan into the water tank. This design utilizes the municipal water supply pressure to drive the exhaust fan, removing chlorine gas from the upper part of the water tank and preventing corrosion from prolonged chlorine accumulation. Furthermore, the exhaust fan in this automatic ventilation device requires no external power supply, consuming neither water nor electricity, making it energy-efficient and environmentally friendly. The larger the water inlet, the faster the exhaust fan operates; the smaller the water inlet, the slower the fan operates. When the water inlet stops, the exhaust fan also stops rotating, extending its service life. Attached Figure Description

Detailed Implementation

[0023] The solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model. In addition, the descriptions involving "first," "second," etc., in this utility model are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated.

[0024] To address the technical deficiencies in related technologies, this utility model provides an automatic ventilation device 10 for water tanks. Please refer to [link / reference]. Figures 1 to 3The automatic ventilation device 10 for the water tank includes: an exhaust duct 100, an exhaust fan 200, a water inlet pipe 300, and a water outlet pipe 400. One end of the exhaust duct 100 is connected to the water tank body 20, and the other end is connected to the external environment. The exhaust duct can be a square pipe, a cylindrical pipe, or other types of pipe, which are not limited here. Specifically, the exhaust duct 100 is provided with an installation section 110, which is provided with an inlet 111 and an outlet 112. The inlet 111 and the outlet 112 are coaxially arranged and respectively located on two opposite sides of the installation section 110. In this way, the water flowing through the inlet 111 can flow from the inlet 111 to the outlet 112 under its own water pressure and be discharged.

[0025] Furthermore, the exhaust fan 200 is installed inside the mounting section 110, and the direction of the rotation axis of the exhaust fan 200 is parallel to the direction of the extension of the mounting section 110. In this way, when the exhaust fan 200 is operating, it can extract the chlorine gas in the water tank from the water tank and discharge it to the external environment through the exhaust pipe 100.

[0026] In addition, one end of the inlet pipe 300 is connected to the municipal water supply pipe, and the other end is connected to the inlet 111. One end of the outlet pipe 400 is connected to the outlet 112, and the other end is connected to the water tank. Water enters through the inlet pipe 300, flows through the inlet 111, and is driven by water pressure to rotate the exhaust fan 200 before flowing into the outlet 112 and then through the outlet pipe 400 into the water tank. With this configuration, while relying on the municipal water supply to the water tank, the exhaust fan can be driven by the inlet pipe 300 to rotate, thus ventilating the water tank at the same time.

[0027] Through the above-mentioned technical effects, the automatic ventilation device 10 for water tanks of this utility model is provided with a ventilation duct 100 connected to the water tank, and an exhaust fan 200 is installed in the ventilation duct 100. The exhaust fan 200 is driven by the water pressure from the municipal water supply inlet pipe 300, and an outlet pipe 400 is also provided to transport the water used to drive the exhaust fan 200 to the water tank. With this configuration, the water pressure of the municipal water supply can be used to drive the exhaust fan 200 to extract air, thereby removing the chlorine gas present in the upper part of the water tank from the water tank, thus preventing the chlorine gas from remaining in the water tank for a long time and corroding the water tank. In addition, the exhaust fan 200 of the automatic ventilation device 10 for water tanks does not require an external power supply, does not consume water or electricity, and is energy-saving and environmentally friendly.

[0028] Furthermore, to ensure that the water flowing from the inlet 111 can drive the exhaust fan 200 to rotate and flow to the outlet 112, in this embodiment, the exhaust fan 200 includes a drive impeller 210 and a fan blade 220. The drive impeller 210 is rotatably installed within the installation section 110, located between the inlet 111 and the outlet 112. The fan blade 220 is detachably connected to the drive impeller 210. With this configuration, when the municipal water supply enters the installation section 110 through the inlet 111, its own water pressure will drive the drive impeller 210 to rotate, thereby driving the fan blade 220 to rotate and provide ventilation.

[0029] In addition, to facilitate the rotation of the water turbine 210 within the mounting section 110, in this embodiment, the mounting section 110 is provided with a fixing frame. The fixing frame includes multiple brackets 120 extending radially along the mounting section 110. A fixing shaft 130 is provided at the axis of the mounting section 110, and the water turbine 210 is rotated and mounted on the fixing shaft 130. It should be noted that the fixing frame can be installed inside the mounting section 110 in a detachable manner, such as by screw fastening or snap-fitting, or it can be installed in a non-detachable manner, such as by welding or riveting. The specific installation method of the fixing frame inside the mounting section 110 is not limited here.

[0030] In this embodiment, the installation section 110 is set up as a cylindrical pipe, and the outer diameter of the fan impeller 220 is clearance-fitted with the inner diameter of the installation section 110. With this setting, the fan impeller 220 rotates under the drive of the water wheel 210, which can better drive the air in the exhaust pipe 100, thereby allowing the air in the water tank to flow from the exhaust pipe 100 to the external environment more quickly.

[0031] Furthermore, to facilitate the connection between the impeller 220 and the drive impeller 210, in this embodiment, the impeller 220 has multiple spaced through holes 230 in its center, and the drive impeller 210 has threaded holes corresponding to each through hole 230 in its center. This allows the impeller 220 and the drive impeller 210 to be connected by screw fastening, which also facilitates subsequent disassembly, cleaning, maintenance, or replacement of the impeller 220.

[0032] Considering that the distance between the water inlet pipe 300 and the water inlet 111 for impacting the wheel plates of the drive impeller 210 is relatively long, potentially resulting in insufficient water pressure, in this embodiment, one end of the water inlet pipe 300 extends from the water inlet 111 into the mounting section 110. This end of the water inlet pipe 300 is positioned adjacent to the drive impeller 210. Furthermore, the water inlet pipe 300 is located on one side of the rotation center of the drive impeller 210, so that the water flowing through the drive impeller 210 impacts the wheel plates of the drive impeller 210. This proximity of the water inlet pipe 300 to the drive impeller 210 facilitates the impact of water from the water inlet 111 onto the wheel plates of the drive impeller 210, thereby driving the drive impeller 210 to rotate. It should be noted that the outlet position of the water inlet pipe 300 can be located to the left or right of the rotation center of the drive impeller 210; this is not limited here.

[0033] In some embodiments, one end of the outlet pipe 400 extends from the outlet 112 into the installation section 110, and the end of the outlet pipe 400 extending into the installation section 110 is provided with a water receiving part 410. By providing the water receiving part 410, the water that flows out of the inlet 111 and drives the water turbine 210 to rotate can flow through the water receiving part 410 into the outlet pipe 400, and then into the water tank, ensuring that water does not stagnate in the installation section 110.

[0034] Considering the long-term presence of humid air, chlorine, and water within the installation section 110, both the drive impeller 210 and the fan impeller 220 are made of aluminum alloy. Aluminum alloy has good corrosion resistance, can work in humid environments for extended periods, and is lightweight, making it easy to rotate under water pressure.

[0035] Please see Figure 4 This utility model also provides a water tank supply system, which includes a water tank body 20, an inlet pipe 30, a supply pipe 40, and an automatic ventilation device 10. One end of the inlet pipe 30 is connected to the municipal water supply pipe, and the water tank body 20 is also connected to the supply pipe 40 to supply water to each household. The other end of the inlet pipe 30 is connected to the water tank body 20. One end of the ventilation pipe 100 is connected to the top of the water tank body 20, and the other end of the ventilation pipe 100 is connected to the external environment. In this way, the inlet pipe 300 can be set with a relatively thin pipe, which has a higher water pressure and makes it easier to drive the exhaust fan 200 to rotate. The inlet pipe 30 is a larger pipe, which provides rapid water supply and avoids insufficient water supply from the water tank.

[0036] In addition, it should be noted that the water inlet pipe 300 of the water tank supply system can also control the rotation speed of the exhaust fan 200 according to the flow rate of water entering the water tank. When the water inlet is large, the water pressure is large, which can increase the speed of the exhaust fan 200 and the exhaust volume is large. When the water inlet is small, the water pressure is small, the speed of the exhaust fan 200 decreases, and the exhaust volume also decreases. The speed of the exhaust fan 200 can be automatically adjusted according to the amount of water inlet.

[0037] The above description is only a part or preferred embodiment of this utility model. Neither the text nor the drawings should limit the scope of protection of this utility model. All equivalent structural transformations made using the content of this utility model specification and drawings under the overall concept of this utility model, or direct / indirect applications in other related technical fields, are included within the scope of protection of this utility model.
