Description

Technical Field

[0001] The utility model belongs to the technical field of drain valves, and in particular relates to an automatic siphon device which controls large-flow liquid discharge by controlling small-flow liquid intake. Background Art

[0002] A common method for draining wastewater in land-based aquaculture involves manually removing pipes or manually activating valves. These methods, however, require significant effort and carry a high risk of error. A second method utilizes a pneumatic automatic drain device, which requires compressed air to power the drain valve and is controlled by a control circuit. This system is relatively complex and prone to failure. A third method is a simple siphon drain, which automatically drains when the external liquid level reaches a certain level and stops automatically when the set discharge volume is reached. However, this device has high requirements for the inlet flow rate at the external liquid level; the inlet flow rate must essentially match the discharge flow rate to trigger siphoning. In practice, if the inlet and discharge flows are roughly equal, draining is unnecessary. Therefore, this type of siphon drain device is not suitable for draining wastewater from fish ponds. The advantage of this device is that it can use a small inlet flow rate, then achieve a sudden, large discharge rate upon reaching the set level. Discharge automatically stops at this level, and then resumes as the external liquid level rises to reach the set level, repeating this cycle. Utility Model Content

[0003] The purpose of this utility model is to address the problem that existing siphon drainage devices require a high inlet flow rate to start drainage, making them unsuitable for land-based fish pond drainage. This utility model proposes an automatic siphon device that uses a small inlet flow to control a large discharge flow. The device can achieve a large discharge flow using a small inlet flow, automatically stops discharging when the set liquid level is reached, and resumes discharging as the external liquid level rises to the set level, repeating this cycle continuously. It is very suitable for draining sewage from land-based aquaculture ponds.

[0004] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions:

[0005] An automatic siphon device for controlling large-flow liquid discharge by small-flow liquid intake comprises a siphon tube; the upper portion of the siphon tube is bent and extends below the surface of liquid to be discharged; a liquid outlet is provided on the side surface of the lower portion of the siphon tube; a piston is provided in the siphon tube; a magnet is provided in the piston; an armature that engages with the magnet is also provided in the siphon tube; an exhaust pipe is provided on the piston; the exhaust pipe passes through the lower portion of the piston and extends into the upper portion of the siphon tube.

[0006] The upper part of the siphon tube is bent and passed into the liquid level below the fish pond. When the liquid level in the fish pond exceeds the lowest point of the bent part of the siphon tube, water enters the siphon tube and the air in the tube is discharged from the exhaust pipe. The water in the siphon tube continues to accumulate. When the gravity of the water in the siphon tube is greater than the sum of the suction force of the armature and the magnet and the friction force on the piston inside the siphon tube, the piston moves downward until the piston reaches below the liquid outlet. At this time, the water in the siphon tube is discharged from the liquid outlet, and the pressure in the siphon tube is instantly reduced. The water in the pool is pressed into the siphon tube under atmospheric pressure, so that a small amount of liquid is triggered to drain a large amount of water. When the water level in the pool to be drained is lower than the siphon tube orifice, air enters the siphon tube, destroying the siphon effect, stopping the siphon, and the piston returns to the top of the liquid outlet to close the drainage.

[0007] As a further technical improvement, the armature is connected to a fixing bracket, which is connected to the inner wall of the siphon tube. The fixing bracket is provided with a through-channel for water flow. The fixing bracket is used to mount the armature; water in the siphon tube can flow out through the through-channel. The fixing bracket can be a thin bracket, ensuring stability while ensuring that the gap between the fixing bracket and the inner wall of the siphon tube, i.e., the through-channel, is large enough to not affect water flow.

[0008] As a further technical improvement, the invention further comprises a piston force adjustment shaft; the lower end of the piston force adjustment shaft is connected to the piston, and the middle portion passes through the armature and the fixing frame; the upper portion of the piston force adjustment shaft is provided with an adjustment nut; an adjustment spring is sleeved on the piston force adjustment shaft between the adjustment nut and the fixing frame. The piston force adjustment shaft can move with the piston; the adjustment nut is rotated to change the compression of the adjustment spring. The greater the compression of the adjustment spring, the greater the force exerted upward on the adjustment nut, the piston force adjustment shaft, and the piston, thereby adjusting the pressure exerted on the piston when pressed downward by water, that is, adjusting the amount of liquid required to start drainage of the siphon; at this time, the piston can only be pushed open when the pressure exerted on the piston by the water in the siphon is greater than the sum of the suction force of the armature and the magnet, the friction force exerted on the piston, and the upward elastic force of the spring.

[0009] As a further technical improvement, the device further includes a siphon liquid level control tube; one end of the siphon liquid level control tube is connected to the top of the curved portion of the siphon tube, and the other end bends and extends below the surface of the liquid to be drained. The siphon liquid level control tube is used to control the liquid level at which the siphon starts and stops. Specifically, only when the liquid level in the fish pond is higher than the orifice of the siphon liquid level control tube will outside air prevent it from entering the siphon tube, allowing siphoning to occur. Conversely, when the liquid level in the fish pond is lower than the orifice of the siphon liquid level control tube, air will enter the siphon tube, destroying the siphon effect and stopping siphoning. Therefore, adjusting the position of the orifice of the siphon liquid level control tube adjusts the liquid level in the fish pond at which siphonic drainage ends.

[0010] As a further technical improvement, the lower portion of the siphon tube is provided with a detachable bottom tube; the connection point between the bottom tube and the siphon tube body is higher than the fixed position of the armature. The bottom tube can be connected to the siphon tube by a threaded connection or other means and is sealed with a sealing ring. The connection point between the bottom tube and the siphon tube is on the fixed frame, so that the fixed frame, armature, piston, magnet, and piston force adjustment shaft are all located on the bottom tube. After removing the bottom tube, the adjusting nut can be rotated to control the amount of water in the siphon tube that pushes the piston open. The liquid outlet is located at the lower portion of the bottom tube.

[0011] As a further technical improvement, the exhaust pipe extends into the curved portion of the upper portion of the siphon pipe. The inlet of the exhaust pipe exceeds the lowest point of the curved portion of the upper portion of the siphon pipe. This ensures that the water level in the siphon pipe is sufficient to push open the piston, rather than entering the exhaust pipe before pushing open the piston.

[0012] As a further technical improvement, the siphon liquid level control tube is a movable tube with an adjustable opening position. The siphon liquid level control tube can be a telescopic tube or a bendable gooseneck tube, etc., as long as the opening position can be adjusted.

[0013] As a further technical improvement, the piston force adjustment shaft is provided with threads on its upper portion; the adjustment nut is movably mounted on the piston force adjustment shaft via the threads. The adjustment nut can be moved to different positions on the piston force adjustment shaft via the threads, and as the adjustment nut moves, the adjustment spring can be compressed to different lengths by the adjustment nut.

[0014] Method for using the above-mentioned automatic siphon device for controlling large-flow liquid discharge by small-flow liquid inlet:

[0015] When in use, the curved part of the siphon tube is extended below the liquid surface of the pool to be drained; as the water level in the pool to be drained continues to rise, when the liquid level in the pool reaches and exceeds the lowest position of the curved section of the siphon tube, water will enter the siphon tube, and the air in the siphon tube will be discharged from the exhaust pipe; because the piston is blocked in the position above the liquid outlet below the siphon tube, the liquid level in the siphon tube continues to rise, and the more water there is, the greater the pressure of the water in the siphon tube on the piston; when the amount of water in the siphon tube is large enough, the downward pressure of the water on the piston is greater than the sum of the suction force of the armature and the magnet, the friction force of the piston on the pipe wall, and the elastic force of the adjusting spring pushing upward, at this time the magnet and the armature suddenly separate, the piston is pushed downward, and the piston exceeds the position of the liquid outlet, causing the water in the siphon tube to instantly flow out of the liquid outlet in large quantities; resulting in a sharp drop in the pressure in the siphon tube, and the water in the pool to be drained is pressed into the siphon tube under atmospheric pressure and discharged from the liquid outlet, reaching a small flow rate in the siphon tube The function of the device is to start large-flow drainage by inlet liquid; adjust the position of the siphon liquid level control pipe orifice. When the water level of the pool to be drained drops below the position of the siphon liquid level control pipe orifice, air enters the siphon pipe, destroying the vacuum in the pipe and stopping the siphon drainage, thereby controlling the siphon drainage stop liquid level; at this time, there is no water flow impacting the piston. Under the action of the adjusting spring force and the suction force of the magnet and the armature, the piston moves upward until the magnet and the armature are completely attracted, and the lower part of the siphon pipe is sealed again; since the pool to be drained no longer siphons drainage, the liquid level begins to rise again under the continuous increase of the liquid inlet flow rate until the liquid level exceeds the lowest position of the curved section of the siphon pipe and a new siphon drainage process begins, and so on; before the above-mentioned use process, the upward elastic force of the adjusting spring on the piston can be changed by rotating the adjusting nut, thereby changing the siphon starting water volume accumulated in the siphon pipe; adjust the position of the siphon liquid level control pipe orifice to adjust the siphon water level depth.

[0016] The technical solution of this utility model has the following beneficial effects:

[0017] 1. This device can achieve sealing in the siphon tube through components such as a piston, a magnet, an armature, and an adjusting spring. When there is enough water in the siphon tube, the piston is pushed open and siphon drainage begins, thereby realizing a small flow of liquid inlet to start a large flow of liquid discharge, making it easier to start the siphon drainage and water exchange in land-based fish ponds and simple and convenient to use.

[0018] 2. This device can change the force required for the piston to be flushed open by water by adjusting the spring and the adjusting nut, thereby controlling the start of the siphon effect of the siphon tube, making the entire siphon drainage adjustable, which is beneficial for users to adjust the use according to actual conditions.

[0019] 3. This device can control the stop liquid level of the siphon action through the siphon liquid level control tube, thereby controlling the liquid level in the pool to be drained, so that the siphon drainage action of the siphon tube is automatically reciprocated.

[0020] 4. This device uses a simple mechanical structure to control small flow and drain large flow. It has a simple and ingenious structure, does not require electricity, has low cost and low failure rate, and is very suitable for sewage discharge and water exchange in fish ponds.
