Description

Technical Field

[0001] The utility model relates to the field of automatic drainage, in particular to a tidal drainage pipe. Background Art

[0002] With the improvement of people's living standards, ornamental fish as an elegant pet has gradually entered thousands of households. In order to provide a comfortable living environment for ornamental fish, various fish tank equipment has emerged. Among them, the drain pipe of the fish tank, as an important part of the fish tank, plays a vital role in maintaining the water quality of the fish tank, reducing the burden of the water pump, and facilitating user cleaning.

[0003] However, in actual use, many users reported that the tidal drain pipe of the fish tank would make abnormal noises at the water inlet when it was working. This abnormal noise not only affects the user experience, but may also scare the creatures in the fish tank and even have a negative impact on the overall structure of the fish tank. Therefore, solving this problem has become a difficult problem that needs to be solved urgently in the industry.

[0004] When the liquid level of a traditional tidal drain pipe reaches the height of the water inlet during drainage, air will be sucked in during the drainage process, causing the water flow to have a greater impact force and turbulence when entering the pipe, thus generating noise. In addition, due to the influence of factors such as pipe materials and installation technology, the water inlet of the tidal drain pipe may also generate noise.

[0005] In order to solve the noise problem of the water inlet of tidal drain pipes, some technical means have been studied and applied. For example, the noise can be reduced by changing the structural design of the pipe, optimizing the flow pattern of the water flow, using noise-absorbing materials, etc. However, these methods often have certain limitations and shortcomings, such as unclear effects, high costs or complex operations. Therefore, further research and development of noise reduction technology for the water inlet of tidal drain pipes has important practical significance and market demand. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model provides a tidal drainage pipe. In order to reduce the noise generated when the tidal drainage pipe is working, a mode in which a through hole is separated from a water inlet is adopted. The height of the through hole is higher than the height of the water inlet. The through hole is opened in advance when the liquid level drops, thereby preventing the noise caused by the inhalation of air when the height of the pool drops to the height of the liquid level at the water inlet during the drainage process.

[0007] The technical problem to be solved by the utility model is achieved through the following technical solutions:

[0008] A tidal drain pipe comprises a guide pipe for assisting in draining liquid, a through hole for communicating with air and a buoyancy device for controlling the opening or closing of the through hole. The guide pipe is provided with a water inlet and a water outlet, the water outlet is lower in height than the water inlet, and the through hole is higher than the water inlet.

[0009] In the above scheme, preferably, the buoyancy device also includes a ball valve, a connecting rod and a float, and the float and the ball valve are fixedly connected to the connecting rod, and the position of the ball valve is controlled to rise and fall by changing the height of the float.

[0010] In the above solution, preferably, the guide tube is overall H-shaped.

[0011] In the above solution, preferably, the float is arranged outside the flow guide pipe, and the ball valve is arranged inside the flow guide pipe.

[0012] In the above scheme, preferably, the diameter of the ball valve is larger than the through hole, and the float is located above the water inlet.

[0013] In the above solution, preferably, the ball valve slides up and down in the flow guide tube.

[0014] In the above solution, preferably, a limiting hole and a vent hole are provided on the top of the guide tube, and the connecting rod slides up and down in the limiting hole.

[0015] Compared with the prior art, the beneficial effects of the utility model are: this scheme provides a tidal drain pipe, adopts a mode in which the through hole is separated from the water inlet, the through hole is located above the water inlet, and a float is used to control the opening or closing of the through hole. During the drainage process, when the liquid level drops to a height close to the water inlet, the through hole is controlled to open, so that air enters the guide pipe to interrupt the siphon and realize flow interruption, avoiding the gas-liquid reverberation generated when the liquid level drops to the level of the water inlet, and at the same time reducing noise to meet the design requirements.

[0024] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions of the various embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments described in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] The embodiment of the utility model provides a tidal drain pipe.

[0026] Embodiment 1, as Figures 1 to 5 As shown, the utility model provides a tidal drainage pipe, whose main structure includes a guide pipe 1 for assisting drainage of liquid, a through hole 2 for circulating with external air and a buoyancy device 3, the buoyancy device 3 is used to control the opening and closing of the through hole 2, the top of the guide pipe 1 is provided with an air hole 10 and a limit hole 9, the overall shape of this scheme is "h"-shaped, the guide pipe 1 is provided with a water inlet 4 and a water outlet 5, the through hole 2 is higher than the water inlet 4, and the siphon principle is adopted, the water flow is introduced into the guide pipe 1 from the water inlet 4, and then discharged from the water outlet 5 The buoyancy device 3 includes a ball valve 6, a connecting rod 7 and a float 8. The connecting rod 7 slides up and down in the limiting hole 9. The ball valve 6 and the float 8 are fixedly connected to the connecting rod 7. The relative positions of the float 8 and the ball valve 6 remain unchanged. During use, the float 8 changes its height according to the size of the buoyancy, driving the ball valve 6 to rise and fall. The ball valve 6 is sealed and connected to the through hole 2. When the float 8 rises, it drives the ball valve 6 to move up and against the through hole 2 to form a closed space to isolate the air.

[0027] The tidal drain pipe designed in the present scheme is installed at the bottom of the water tank, and the water outlet 5 is connected to the outside. When in use, water is poured into the water tank. As the liquid level gradually rises, the float 8 begins to float up, driving the ball valve 6 to rise and seal the through hole 2, so that a sealed space is formed in the guide tube 1. The water in the water tank enters the guide tube 1 through the water inlet 4, and the liquid level gradually rises until the guide tube 1 is filled with liquid and siphon diversion begins. After the drainage work starts, the drainage speed is greater than the water filling speed, and the liquid level in the water tank drops. The buoyancy of the float 8 decreases and the height drops accordingly. When the liquid level has not reached the height of the water inlet 4, the ball valve 6 drops and disengages from the through hole 2, and the outside air enters the guide tube 1 through the air vent 10, cutting off the siphon diversion and terminating the drainage work in advance, thereby avoiding the noise caused by the gas-liquid reverberation when the liquid level drops to the height of the water inlet 4. The automatic regulation and discharge of the water flow are achieved through the design of the drain pipe.

[0028] Working principle: When the tidal water level rises, the water in the water tank flows into the pipe through the inlet of the tidal drainage pipe. Due to the sealing design of the ball valve and the through hole in the drainage pipe, the water flow rate slows down, the kinetic energy is reduced, and the water accumulates in the drainage pipe. When the water level rises to the height of the pipe, the air inside the guide pipe is squeezed out, forming a siphon, and the water begins to flow out. After the water flows out, the ball valve in the guide pipe separates from the through hole, and the air enters the air hole set at the top, the siphon ends, and then the water pump adds water again to form a siphon again. In this process, the flow rate of the water pump must be less than the water outflow of the siphon pipe to produce the effect of tidal drainage.

[0029] The utility model provides a tidal drain pipe, the main structure of which includes a guide pipe for assisting the drainage of liquid, a through hole for air circulation, and a buoyancy device for controlling the opening or closing of the through hole, the guide pipe is provided with a water inlet and a water outlet, the through hole is higher than the water inlet. The buoyancy device also includes a ball valve, a connecting rod and a float, the float is fixedly connected to the ball valve on the connecting rod, the relative position of the float to the ball valve remains unchanged, and the position of the ball valve is controlled to rise and fall by changing the height of the float.

[0030] The buoyancy device is installed in the ventilation pipe, and the ventilation pipe is connected to the guide pipe. The buoyancy device slides up and down in the ventilation pipe with the buoyancy. The diameter of the ball valve is larger than the diameter of the through hole. When the float rises, it drives the ball valve to rise, and the ball valve presses against the through hole to achieve sealing.

[0031] During drainage, the through hole is closed, and liquid enters the guide tube from the water inlet and is discharged through the water outlet. When the liquid level drops to a height close to the water inlet during drainage, the float drops in height due to reduced buoyancy, and the ball valve drops accordingly, so that the through hole opens, allowing air to enter the guide tube to interrupt the siphon and cut off the flow, thereby avoiding noise generated during drainage and achieving the design purpose.
