Technical Field

[0001] The utility model belongs to the field of commercial vehicles, and in particular relates to an air storage cylinder assembly capable of automatically discharging sewage. Background Art

[0002] At present, most of the common gas tanks in commercial vehicles on the market use manual drain valves, such as Figure 1 As shown, the manual drain valve is set in the air cylinder interface. By lifting the manual drain valve upward, the sealing gasket of the manual drain valve is separated from the air cylinder interface, leaking a gap, and then the air cylinder interface can be opened. However, this method requires the driver to manually drain the accumulated water and oil in the air cylinder regularly, which not only has the risk of omission, but also causes the gas circuit parts to rust and clog if manual drainage is not performed for a long time, resulting in various parts failures, which may delay the transportation efficiency at the least and cause serious traffic accidents at the worst.

[0025] The present invention will be further described in detail below in conjunction with specific embodiments so that those skilled in the art can understand the present invention more clearly.

[0026] It should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrally formed structure. For ordinary technicians in this field, the specific meanings of such terms in this patent can be understood according to specific circumstances.

[0027] Example 1

[0028] like Figure 2-3 As shown, this embodiment provides an air storage cylinder assembly capable of automatically draining sewage, including a drain valve 4, a humidity sensor 3, a controller, a magnetic attraction unit 2, and a coil 6.

[0029] The drain valve 4 is arranged at the lowest interface of the air cylinder 1. Specifically, the drain valve 4 is a columnar structure. The drain valve 4 passes through the interface of the air cylinder 1. A pull ring is fixed to the outer end of the drain valve 4. A sealing gasket 7 is fixed on the outer side of the drain valve 4. The sealing gasket 7 is located in the air cylinder 1. Under the action of the internal pressure of the air cylinder 1, the sealing gasket 7 abuts against the inner wall of the interface of the air cylinder 1, thereby closing the interface of the air cylinder 1.

[0030] The humidity sensor 3 is arranged inside the gas cylinder 1, and the humidity sensor 3 can detect in real time the water accumulation inside the gas cylinder 1. The humidity sensor 3 is electrically connected to the controller, and the humidity sensor 3 can transmit the detected humidity information to the controller in real time.

[0031] The coil 6 is sleeved on the inner end of the drain valve 4, and the coil 6 is fixedly connected to the drain valve 4, similar to an electromagnet. The coil 6 is electrically connected to the controller, and the controller can automatically control the power on and off of the coil 6.

[0032] The magnetic unit 2 is arranged at the interface of the gas cylinder 1 , and the magnetic unit 2 is located inside the coil 6 .

[0033] Based on the above structure, when the driver needs to manually discharge sewage, such as Figure 4 As shown, the drain valve 4 is lifted up to leave a gap for sewage discharge.

[0034] If the driver forgets to manually drain the waste, when the humidity inside the air cylinder 1 reaches the set value, the resistance and capacitance of the humidity sensor 3 change, and transmit the signal to the controller, and the controller controls the coil 6 to be energized. After the current flows through the coil 6, it has magnetism and generates mutual attraction with the magnetic unit 2. Since the magnetic unit 2 is fixed, it will generate an inward suction force on the drain valve 4, causing the drain valve 4 to move inward and leak out a gap, such as Figure 5As shown, the interface of the gas cylinder 1 is opened, and the interior is connected to the atmosphere, realizing the automatic sewage discharge function. When the humidity inside the gas cylinder 1 drops below the set value, the humidity sensor 3 transmits a signal to the controller, and the controller controls the coil 6 to be powered off, the magnetism disappears, and the drain valve 4 is reset under the action of the internal pressure, automatically closing the interface of the gas cylinder 1.

[0035] Therefore, the air cylinder assembly with automatic sewage discharge provided in this embodiment retains the original manual sewage discharge function and adds an automatic sewage discharge function, which can discharge sewage reliably and accurately, effectively prevent the failure of air circuit components due to the failure of the air cylinder to discharge sewage in time, and can also perform manual sewage discharge in maintenance and disassembly environments.

[0036] Please refer again Figure 2 The humidity sensor 3 is installed at the inner end of the drain valve 4, so that the humidity sensor 3 can detect the humidity at the bottom of the gas cylinder 1, and at the same time can reduce the impact of the humidity sensor 3 on the internal environment of the gas cylinder 1.

[0037] The magnetic unit 2 is a magnet and has an annular structure. The magnetic unit 2 is installed at the inner end of the interface of the gas cylinder 1, and the probe of the humidity sensor 3 passes through the magnetic unit 2. Interference between the humidity sensor 3 and the magnetic unit 2 can be avoided.

[0038] The inner end of the drain valve 4 is made of ferromagnetic material, which is easier to be magnetized under the action of a magnetic field, thereby increasing the magnetic strength of the electromagnet.

[0039] Please refer again Figure 3 The side wall of the drain valve 4 is provided with a through hole for the wire harness to pass through. For example, the humidity sensor and the coil wire harness 5 can pass through the through hole of the drain valve 4, avoiding the need for the wire harness to come out from the gap between the drain valve 4 and the gas cylinder 1, ensuring the sealing of the interface between the drain valve 4 and the gas cylinder 1, and preventing the wire harness from being clamped.

[0040] Example 2

[0041] like Figure 6 As shown, on the basis of Example 1, this embodiment further includes a limiting sleeve 8, which is a concave structure, and the limiting sleeve 8 is adapted to the interface of the air cylinder 1. The limiting sleeve 8 clamps the interface of the air cylinder 1 inside, and the limiting sleeve 8 is fixed to the interface of the air cylinder 1 by bolts.

[0042] The bottom plate of the limiting sleeve 8 is penetrated with a sliding hole adapted to the drain valve 4, and the drain valve 4 is slidably inserted in the sliding hole, so that the drain valve 4 is more stable during the inward and outward movement. When manual sewage discharge is required, the limiting sleeve 8 can be removed first to facilitate subsequent operations. After the operation is completed, the limiting sleeve 8 can be installed again, which is simple and convenient. In addition, the bolt holes for fixing are located on the two side plates of the limiting sleeve 8, which can prevent the inner end of the bolt from affecting the sealing gasket 7.

[0043] The limiting sliding sleeve 8 may be a hollow structure to facilitate the flow of accumulated water and oil.

[0044] The mechanisms, components and parts not specifically described in the present invention are all existing structures in the prior art and can be directly purchased from the market.
