Description

Technical Field

[0001] The utility model relates to the technical field of drainage systems, in particular to a drainage system based on the siphon principle. Background Art

[0002] Drainage system refers to the overall combination of drainage collection, transportation, water quality treatment and discharge facilities in a certain way. It is a general term for drainage ditches (pipes) and buildings at all levels for waterlogging, waterlogging and salt prevention.

[0003] For the discharge and flow monitoring of leachate, the original practice is to add a certain volume of ton barrels on the main pipe for leachate discharge. When the seepage is started, the leachate in the ton barrel is temporarily stored for a certain amount, and then the valve of the water outlet at the bottom of the ton barrel is controlled by the on-site workers. To ensure the correct reading of the electromagnetic flowmeter on the outlet pipe, an inverted U-shaped pipe is installed at an appropriate position on the downstream drainage pipe of the flowmeter to ensure that the water pipe is always full of pipe flow. The most obvious defect of this practice is that the accuracy of liquid flow monitoring data is difficult to control and requires manual supervision. The range ratio of high-precision electromagnetic flowmeters on the market is basically 1:10, and the range of the on-site flowmeter is set according to the estimate, such as 4 to 40 cubic meters per hour. In theory, only when the water level in the ton barrel is within a certain height range, opening or closing the drainage valve can ensure the accurate reading of the flowmeter. In actual operation, it is difficult for humans to grasp this point, and it is not practical enough. Therefore, it is necessary to redesign a drainage system based on the siphon principle to address the above problems. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a drainage system based on the siphon principle.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-4 A drainage system based on the siphon principle includes a ton barrel 1, a water inlet pipe 2 connected to the interior is fixedly installed on the outer wall of the ton barrel 1, an electromagnetic flowmeter 4 is fixedly connected to the end of the water inlet pipe 2 through a valve 3, a liquid level micro-control device 5 is fixedly installed on the outer wall of the water inlet pipe 2, an outer sleeve is slidably installed on the outer wall of the liquid level micro-control device 5, an inverted sleeve 6 is slidably installed on the outer wall of the outer sleeve, the water inlet pipe 2 is L-shaped, the water inlet pipe 2 and the inverted sleeve 6 are both PE pipes, the upper end surface of the inverted sleeve 6 is fixedly connected to an exhaust pipe 7 through a connecting mechanism, the connecting mechanism includes a connecting pipe fixedly installed on the upper end surface of the inverted sleeve 6, the connecting pipe is connected to the inside of the inverted sleeve 6, and the exhaust pipe 7 is fixedly installed on the outer wall of the connecting pipe.

[0022] A counterweight block 10 is fixedly installed on the inner bottom wall of the ton barrel 1, a positioning line 9 is fixedly installed between the counterweight block 10 and the ton barrel 1, a floating block 8 is fixedly installed on the outer wall of the positioning line 9, the exhaust pipe 7 passes through the floating block 8, a pendant 11 is fixedly installed on the end of the exhaust pipe 7, two obstacles 12 are fixedly installed on the outer wall of the positioning line 9, and a rubber hose 13 is installed on the outer wall of the outer sleeve. The rubber hose 13 is made of vulcanized rubber. Vulcanized rubber refers to vulcanized rubber, which has the characteristics of not being sticky and not easy to break. It also has high elasticity, heat resistance, tensile strength and insolubility in organic solvents. Two buoyancy counterweight tubes 14 are fixedly installed on the outer wall of the outer sleeve through elastic hoses. Both buoyancy counterweight tubes 14 are made of plastic. Thin hoses 15 are slidably installed on the outer walls of the two buoyancy counterweight tubes 14 through openings. Counterweight iron nails 16 are installed inside the two buoyancy counterweight tubes 14, and the counterweight iron nails 16 can increase the weight of the buoyancy counterweight tubes 14.

[0023] When the utility model is used, when the liquid level in the ton barrel 1 is low and the buoyancy of the entire liquid level micro-control device 5 is less than its gravity, the elastic hose directly bears the gravity (downward pull) of the entire fine-tuning device. As the liquid level rises, the buoyancy of the buoyancy counterweight tube 14 gradually increases. When the buoyancy is greater than the gravity of the entire system, the liquid level micro-control device 5 will rise along the vertical pipe of the water inlet pipe 2 with the liquid level, and gradually rise above a certain height (preferably not greater than the outer diameter of the pipe mouth of the water inlet pipe 2) at the mouth of the water inlet pipe. After the liquid level continues to rise, the liquid level micro-control device 5 is subjected to the buoyancy, gravity and downward pull of the elastic hose. After the elastic hose is subjected to the surrounding liquid pressure, it will have a certain radial deformation (the buoyancy counterweight tube 14 provides upward buoyancy). When the liquid level reaches the buoyancy, the liquid level micro-control device 5 will rise along the vertical pipe of the water inlet pipe 2 with the liquid level, and gradually rise above the mouth of the water inlet pipe 2 to a certain height (preferably not greater than the outer diameter of the mouth of the pipe). After the upper opening of the counterweight tube 14, the buoyancy counterweight tube 14 will gradually be filled with liquid and will fall along the vertical pipe of the water inlet pipe 2. At this time, the liquid in the inverted sleeve barrel 6 will quickly fill the vertical pipe of the water inlet pipe 2 and flow out from the final outlet at a certain speed. With this round of liquid discharge, the siphon effect of the drainage system will be triggered, and the flow rate of liquid discharge will be accelerated and reach a certain value. At the same time, the liquid level micro-control device 5 will be completely sunk into the water body. In theory, the thin hose 15 on the buoyancy counterweight tube 14 will be completely filled with liquid. When the amount of water entering the ton barrel 1 is less than the amount of the siphon drainage system, the liquid discharge will reach the preset minimum water level in the ton barrel 1, and the liquid level in the inverted sleeve barrel 6 will drop rapidly at the same time. At this time, the buoyancy counterweight tube 14 will be completely exposed to the liquid surface, and the liquid in it will be quickly emptied by the siphon effect of the thin hose 15 on it. The drainage system returns to the initial state and waits for the next round of drainage. The electromagnetic flowmeter 4 can monitor the size of the drainage volume.

[0024] During the drainage process, one end of the exhaust pipe 7 passes through the center of gravity of the float 8 and is immersed in the liquid to a certain depth. The gravity provided by the pendant 11 is less than the maximum buoyancy that the float 8 can provide. The float 8 will rise and fall within the set height range as the liquid level rises and falls. The float 8 can float up and down vertically through the positioning line 9. When the water pressure difference that may exist inside and outside the inverted barrel 6 prompts the gas inside it to be discharged from the exhaust pipe 7, when the liquid level of the ton barrel 1 reaches the water level where the siphon effect occurs, the exhaust pipe 7 is converted into a suction pipe under atmospheric pressure and discharges a certain amount of residual gas in the inverted barrel 6. When the height of the float 8 approaches the top position of the main body of the inverted barrel 6, the obstacle 12 on the positioning line 9 will limit its further rise. During the rise or fall of the float 8, the pendant 11 under the center of gravity provides downward traction and prevents the occurrence of adverse situations such as overturning of the float 8 due to swells.

[0025] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
