Abstract
Description
Technical Field
[0001] The utility model relates to the technical field, and in particular refers to a drainage pipeline connection port with an air pressure regulating device. Background Art
[0002] With the increase in the number of deep foundation pit construction projects, the difficulties in drainage pipeline engineering are becoming more and more prominent. The primary problem is how to ensure that the water in the pipeline that is hundreds of meters long can flow freely and unimpeded. The conventional practice is to weld a "breathing port" on the main pipeline, but the height and number of the "breathing port" can still cause the water flow rate to be too slow. Utility Model Content
[0003] In order to solve the above-mentioned problems, the utility model proposes a drainage pipeline connection port with an air pressure regulating device, in which the positive and negative air pressures in the drainage pipeline can be freely adjusted to prevent the water flow speed from being too slow.
[0004] In order to solve the above-mentioned technical problems, the technical solution proposed in the utility model is: a drainage pipeline connection port with an air pressure regulating device, including an artificial air pressure regulating device, an air intake device, a gas check valve, an exhaust device, and an outward-expanding trumpet outlet, which are arranged in sequence along the direction of water flow, the artificial air pressure regulating device is connected to the very end of the straight drainage pipe, the exhaust device is connected to the very end of the straight drainage pipe, the air intake device is arranged between the artificial air pressure regulating device and the exhaust device, and the gas check valve is arranged in the straight drainage pipe between the air intake device and the exhaust device.
[0005] Furthermore, the exhaust device is composed of an organized drainage port, an exhaust device head cover, a wave curve spring coil 1, a hemispherical piston, and a telescopic sleeve rod. The organized drainage port is connected and arranged at the lower end of one side of the exhaust device head cover. The wave curve spring coil 1 and the hemispherical piston are arranged in the exhaust device head cover. The telescopic sleeve rod is arranged between the hemispherical piston and the exhaust device head cover, and is arranged outside the wave curve spring coil 1. The gas in the tube pushes the hemispherical piston outward, and the hemispherical piston compresses the telescopic sleeve rod and squeezes the wave curve spring coil 1 at the same time, so that the upper plane of the hemispherical piston and the lower opening end of the exhaust device head cover form an airway, and the gas can be freely discharged from the pipeline.
[0006] Furthermore, the air intake device is composed of a cloud top cap, a second wave curve spring coil, a flower eye air intake disk, an air intake device helmet and an air intake sleeve rod. The air intake device helmet is arranged at the outermost side, the second wave curve spring coil connects the cloud top cap and the flower eye air intake disk, and the air intake sleeve rod is arranged between the cloud top cap and the flower eye air intake disk, and is arranged outside the second wave curve spring coil. The external atmospheric pressure presses down the cloud top cap, and at the same time drives the second wave curve spring coil to change in the axial direction, and finally enters the drainage pipe through the hole of the flower eye air intake disk, so that the water in the pipe can flow freely and ensure the appearance of the pipe wall is intact. The air intake device helmet has a cylindrical appearance, and the upper part is an arc-shaped opening device, which is mainly provided to allow the cloud top cap to move freely up and down under the action of external air pressure.
[0007] Furthermore, the gas check valve is composed of a movable fan clamp, a movable fan connecting main rod and a movable fan leaf. The movable fan clamp and the movable fan connecting main rod support two movable fan leaves so that they can be opened and closed freely. The length of the movable fan connecting main rod is the same as the diameter length of the movable fan leaf. It is made of metal and plays a role in supporting the movable fan leaf, so that the movable fan leaf can be opened and closed freely without deformation under the action of water flow.
[0008] Furthermore, the artificial air pressure regulating device is composed of a barometer and an artificial gas connection port. When the pointer of the barometer changes greatly in the clockwise direction, it indicates that the positive atmospheric pressure in the pipeline increases, and the artificial gas connection port is activated to perform artificial "air extraction" to ensure the normal operation of the water flow in the pipeline.
[0009] Furthermore, a horizontal outward-expanding trumpet outlet is connected to the end of the vertical drainage pipe. The top of the trumpet outlet needs to be buried within a certain depth range below the water flow surface to ensure smooth drainage without gas entering, especially in the dry season, the upper end of the trumpet outlet does not overflow to the river or lake surface.
[0010] Compared with the prior art, the utility model has the following advantages:
[0011] The exhaust device can timely discharge the excess gas in the pipeline, preventing the end gas in the pipeline from entering the pipe. The air intake device allows the gas to freely enter the pipeline from the outside, so that the pressure difference between the inside and outside of the pipeline reaches a relative balance, so that there will be no depression, pits, pressure loss and other phenomena on the outer wall of the pipeline. The top of the outward-expanding trumpet outlet needs to be buried within a certain depth range below the water surface. Ensure smooth drainage without gas entering, especially in the dry season, the upper end of the trumpet does not overflow to the surface of rivers and lakes. The artificial gas connection port is a T-shaped structural device. After it is removed, an external gas pump can be connected to meet the intake and exhaust of the artificial air pressure regulating device, and a barometer needs to be combined to determine the required amount of gas.

[0020] The utility model is further described in detail below in conjunction with the accompanying drawings.
[0021] Combined with Figure 1 To Attachment Figure 7 :
[0022] The following sequence is arranged along the water flow direction: an artificial air pressure regulating device 4, an air intake device 2, a gas check valve 3, an exhaust device 1, and an outward-expanding trumpet outlet 5, which are respectively placed at the straight section of the external drainage pipe and the end water inlet of the pipe.
[0023] The exhaust device 1 is placed on the outer water pipe and at the end of the straight drain pipe, that is, at the transition from the straight section to the "bend neck" section. The main function is to discharge the excess gas in the pipe in time and prevent the end gas in the pipe from entering the pipe.
[0024] The air intake device 2 is located upstream of the gas check valve 3, and mainly provides gas to freely enter the pipeline from the outside, so that the pressure difference inside and outside the pipeline reaches a relative balance, and the outer wall of the pipeline does not have depressions, pits, pressure loss, etc.
[0025] The gas check valve 3 is placed in the drainage pipe, located in the middle of the air intake device 1 and the exhaust device 2. In the normal working state of drainage, the movable fan leaf 33 is closed, and the water flow can pass freely. When the external gas enters the drainage pipe from the outward expansion trumpet outlet 5, the gas will be partially discharged through the exhaust device 1. However, when the gas is not completely discharged, the movable fan leaf 33 in the gas check valve 3 is activated, and the movable fan leaf 33 opens its "wings" to block the entry of external gas. Especially when there is a sudden power outage at the construction site, the water pump stops working, the water flow in the pipeline is reduced, and it is easier for gas to enter the pipe body. At this time, the important role of the gas check valve 3 is reflected.
[0026] The artificial air pressure regulating device 4 is placed on the drainage pipe, at the end of the straight section. The air pressure in the pipe can be known more accurately through the barometer 41. The function is to balance the air pressure in the pipe in terms of "size, positive and negative" so that the water in the drainage pipe can flow smoothly and unobstructed. When the pointer of the barometer 41 fluctuates greatly, the artificial air pressure regulating device 4 is turned on. By connecting an external air pump, the effect of extracting the gas in the pipe when the positive pressure is large and injecting gas when the negative pressure is large is achieved.
[0027] The outward expansion bell outlet 5 is placed at the end of the drainage pipe, i.e., the water outlet. The top of the bell outlet needs to be buried within a certain depth range below the water flow surface. It is ensured that the drainage is smooth and no gas enters, especially in the dry season, the upper end of the bell outlet does not overflow the river or lake water surface.
[0028] When the air pressure in the pipeline increases, it is necessary to discharge the excess gas in the pipe to ensure the normal operation of the drainage construction. The working principle is that the gas in the pipe pushes the hemispherical piston 14 outward, and the hemispherical piston 14 compresses the telescopic sleeve 15, and squeezes the wave curve spring coil 13 at the same time, so that the upper plane of the hemispherical piston 14 and the lower open end of the exhaust device head cover 12 form an airway, and the gas will be freely discharged from the pipeline. When exhausting in flowing water, it is inevitable that there will be a "splashing" phenomenon. Then the utility model needs to arrange an organized drain port 11 at the bottom of the exhaust device head cover 12. The organized drain port 11 is composed of a straight section and a downward inclined section of a water pipe, and the exhausted gas and the water carried in the gas are discharged out of the pipe together, and the water flows into the river and lake water along the inclined section of the water pipe. Such a structure reflects the purpose of civilized construction.
[0029] The exhaust device head cover 12 is the entire outer cover of the exhaust device 1, and its shape is rectangular, with a sealed upper portion and an opening at the lower portion. The length of the opening is smaller than the length of the flat surface of the hemispherical piston 14, and its function is to hinder the descent of the hemispherical piston 14. A drainage tube with an organized drainage port 11 needs to extend outward from the outer side of the lower opening. The height of the exhaust device head cover 12 is the same as the length of the free extension of the shrink sleeve rod 15. The width requirement is that it does not hinder the free extension of the wave curve spring coil 13.
[0030] The wave curve spring ring 13, the hemispherical piston 14, and the telescopic sleeve 15 are integrated as a whole. The gas in the drain pipe lifts the hemispherical piston 14, and at the same time compresses the wave curve spring ring 13 and the telescopic sleeve 15 to deform in the axial direction, so that the hemispherical piston 14 and the lower part of the exhaust device head cover 12 form an air passage, and finally discharge the excess gas. The hemispherical piston 14 is made of rubber, mainly to meet the fitting effect at the lower opening of the exhaust device head cover 12. The hemispherical piston 14 has a hemispherical appearance, with a flat surface on the upper part and an arc curve on the lower half, which is convenient for driving the wave curve spring ring 13 and the telescopic sleeve 15 to sink to the lower opening of the exhaust device head cover 12 under the action of its own weight. The telescopic sleeve 15 is arranged inside the curve spring ring 13, and the telescopic sleeve 15 plays the role of fixing and supporting the curve spring ring 13. The telescopic sleeve rod 15 is composed of two rods, the outer diameter of the upper rod is smaller than the outer diameter of the lower rod, and the upper rod can freely shuttle inside the lower rod under pressure. The material strength is greater than the deadweight requirement of the hemispherical piston 14.
[0031] When the negative pressure in the drainage pipe is so large that the pipe wall cannot resist the negative pressure in the pipe, the pipe wall will naturally deform, pit and dent. The utility model is designed to automatically open the air intake device 2. The external atmospheric pressure presses down the cloud top cap 21, and at the same time drives the wave curve spring coil 22 to change in the axial direction, and finally enters the drainage pipe through the hole of the flower eye air intake disc 23, so that the water in the pipe can flow freely and ensure the appearance of the pipe wall is intact. The air intake device helmet 24 has a cylindrical appearance, and the upper part is an arc-shaped opening device, which is mainly used to provide the cloud top cap 21 to move up and down freely under the action of external air pressure. The width and height of the air intake device helmet 24 can be the same as the height and width of the exhaust device hood 12. The air intake device helmet 24 is mainly used to cover the wave curve spring coil 22, the flower eye air intake disc 23, and the air intake sleeve rod 25. The flower eye air intake disc 23 is a disc, and a number of flower eye holes are punched in the disc, which mainly form a channel for gas to enter the drainage line. The material of the disc must meet certain strength and rigidity, and its diameter must be larger than the lower opening of the air intake helmet 24, that is, it can be supported at the lower opening of the air intake helmet 24. The air intake sleeve rod 25 is two metal rods, the diameter of the upper rod is larger than the diameter of the lower rod, and under the action of external air pressure, it can freely expand and contract and fall along the lower rod.
[0032] The main function of the movable fan clamp 31 and the movable fan connecting main rod 32 is to support the two movable fan leaves 33 to open and close freely. The movable fan leaf 33 is made of hard plastic sheet, composed of two pieces, and has a semicircular shape. Its diameter length should be just smaller than the diameter of the inner wall of the pipe, and the length that does not hinder the free opening and closing under the action of drainage is sufficient. The movable fan clamp 31 is made of square metal material, and its main function is to connect the movable fan clamp 31 and the movable fan connecting main rod 32. The length of the movable fan connecting main rod 32 is the same as the diameter length of the movable fan leaf 33. It is made of metal material, which plays the role of supporting the movable fan leaf 33, and satisfies the movable fan leaf 33 to open and close freely under the action of water flow without deformation.
[0033] When the pointer of the barometer changes greatly in the clockwise direction, it indicates that the positive atmospheric pressure in the pipeline increases, and the artificial gas connection port 42 is started to artificially "pump air" to ensure the normal operation of the water flow in the pipeline. When the pointer of the barometer changes greatly in the counterclockwise direction, it indicates that the negative pressure in the pipeline increases, and the artificial gas connection port 42 is started to artificially "fill air" to meet the occurrence of the lossless phenomenon of the outer wall of the pipeline. The artificial gas connection port 42 is a T-shaped structural device. After being unplugged, an external gas pump can be connected to meet the intake and exhaust of the artificial air pressure regulating device 4, and the required amount of gas needs to be determined in combination with the barometer 41.
[0034] Specific implementation of the utility model: When the utility model is in use, the outward expansion trumpet outlet 5 is placed at the very end of the drainage pipe, that is, the water outlet, to ensure that the drainage is smooth and no gas enters, especially in the dry season, the upper end of the trumpet outlet does not overflow the river and lake water surface. When the pointer of the barometer 41 changes greatly in the clockwise direction, it indicates that the positive atmospheric pressure in the pipeline increases, and the artificial gas connection port 42 is started to perform artificial "air extraction" to ensure the normal operation of the water flow in the pipeline. When the pointer of the barometer changes greatly in the counterclockwise direction, it indicates that the negative pressure in the pipeline increases, and the artificial gas connection port 42 is started to perform artificial "air filling". The eyelet air intake disk 23 is a disk, and several eyelet holes are punched in the disk, mainly to form a channel for gas to enter the drainage pipeline. The material of the disk must meet certain strength and rigidity, and its diameter must be larger than the lower opening of the air intake device helmet 24, that is, it can be supported at the lower opening of the air intake device helmet 24. The air intake sleeve 25 is composed of two metal rods. The diameter of the upper rod is larger than that of the lower rod. Under the action of external air pressure, it can freely extend and contract along the lower rod to be deformed. The length of the main rod 32 connected to the movable fan is the same as the diameter length of the movable fan leaf 33. It is made of metal and plays the role of supporting the movable fan leaf 33, so that the movable fan leaf 33 can be opened and closed freely under the action of water flow without deformation. The three devices of the wave curve spring ring 13, the hemispherical piston 14, and the telescopic sleeve 15 are integrated as a whole. The gas in the drain pipe lifts the hemispherical piston 14, and at the same time compresses the wave curve spring ring 13 and the telescopic sleeve 15 to deform in the axial direction, so that the hemispherical piston 14 and the lower part of the exhaust device head cover 12 form an air passage, and finally discharge the excess gas.
[0035] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0036] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
