Description

Technical Field

[0001] The utility model relates to the technical field of tire inflators, in particular to a water discharging device for a tire inflator of a transport vehicle. Background Art

[0002] When the tire of a transport vehicle is damaged, whether it is out of air or the tire is broken, it ultimately needs to be repaired and then a tire inflator is used to inflate the tire until the tire reaches the standard for being able to hit the road again.

[0003] In the past, for a tire inflator, air in the atmosphere was pressed into the air pump and then into the tire through the air pump. However, due to the certain humidity in the air, after the air was pressed into the air pump, over time, the humid air became water droplets after being under high pressure, and a lot of water would form inside the inflator and accumulate at the bottom of the inflator. If the pressure is not reduced to drain the water at the bottom of the inflator, the gas pressure will be too high and the water will be quickly pressed out. The water with pressure is somewhat dangerous. Therefore, when draining this water, first the pressure of the whole tank of gas in the inflator needs to be reduced to be equal to the atmospheric pressure, and then the water discharge port below the inflator is opened. However, in this way, when using the inflator again, more electrical energy is consumed to pressurize the air pump again. Summary of the Utility Model

[0004] In order to effectively drain the water in the air pump while maintaining the air pressure in the air pump and not consuming too much electrical energy, the utility model provides a water discharging device for a tire inflator of a transport vehicle.

[0005] The water discharging device for a tire inflator of a transport vehicle provided by the utility model adopts the following technical scheme:

[0006] A water discharging device for a tire inflator of a transport vehicle includes an air pump and a liquid pump;

[0007] A flow guide pipe is connected between the air pump and the liquid pump. One end of the flow guide pipe is installed at the lowermost end of the air pump, and the other end is connected to the liquid pump. A first switch valve is arranged on the flow guide pipe, and the liquid pump is detachably connected to the flow guide pipe.

[0008] By adopting the above technical scheme, a liquid pump is connected. After the first switch valve is opened, the liquid flows into the liquid pump. The spaces of the air pump and the liquid pump are still closed. Most of the liquid pump is filled with liquid and there is very little air. Only a small part of the pressure in the air pump is lost and enters the liquid pump. When the first switch valve is closed, the pressure in the air pump is still higher than the atmospheric pressure. At this time, only the liquid pump needs to be removed, held upward, a small amount of gas inside is released, and then the liquid is poured out. After the pressure of the liquid pump is reduced, the danger of pouring water is avoided, and there is no need to reduce the pressure in the air pump before draining the water, effectively avoiding excessive consumption of electrical energy for subsequent inflation of the air pump.

[0009] Preferably, one end of the air pump is connected with an air duct, the air duct is connected with the liquid pump, a pressure balance pipe is arranged on one side of the air duct, the pressure balance pipe is communicated with the outside atmosphere, a second switch valve is arranged on the air duct, and a third switch valve is arranged on the pressure balance pipe.

[0010] By adopting the above technical solution, to avoid the liquid in the air pump flowing into the liquid pump instantaneously with too large an impact force, an air duct is connected between the air pump and the liquid pump. First, the second switch valve is opened to allow part of the gas to flow into the liquid pump, and then the first switch valve is opened, and the liquid flows in, squeezing the gas in the liquid pump back into the air pump. At this time, when the liquid flows in, since the pressure between the liquid pump and the air pump is the same, the liquid will not have too large an impact when flowing downward, effectively avoiding the danger caused by too large an impact. In addition, if the pressure in the air pump is too high, the third switch valve can be opened to release a little gas and then the operation can be carried out, effectively ensuring the safety of the staff.

[0011] Preferably, a compression motor is installed on the air pump, and a power protector is installed on one side of the compression motor.

[0012] By adopting the above technical solution, the compression motor compresses the gas, and a power protector is additionally provided to prevent the compression motor from being damaged due to unstable power supply.

[0013] Preferably, an air filter is installed on the air pump, and multiple filter elements are arranged inside the air filter.

[0014] By adopting the above technical solution, there will be a lot of dust in the air. By setting an air filter, the dust entering the air pump can be effectively reduced, and only air can enter.

[0015] Preferably, a fixed installation net is arranged on the air pump, and both the compression motor and the air filter are installed on the fixed installation net.

[0016] By adopting the above technical solution, the compression motor and the air filter need to be fixed, and the air pump needs to ensure the integrity of its shell as much as possible. Therefore, as few bolts and welded parts as possible are set for fixing too many devices. By setting a fixed installation net, the number of devices installed on the air pump can be effectively reduced.

[0017] Preferably, a pressure gauge is arranged on the air pump, and the pressure gauge is used to detect the pressure value inside the air pump.

[0018] By adopting the above technical solution, by installing a pressure gauge and checking the pressure value at any time, the pressure value in the air pump can be effectively prevented from being too high.

[0019] Preferably, a pneumatic pressure controller is provided on the air pump. One end of the pneumatic pressure controller is provided with an air outlet, and the pneumatic pressure controller is connected to a pressure dashboard. The pneumatic pressure controller controls the opening and closing of the air outlet according to the pressure value.

[0020] By adopting the above technical solution, according to the pressure value, the opening and closing of the air outlet are automatically controlled, effectively avoiding dangerous situations when the staff cannot see.

[0021] Preferably, a moving component is provided at the lower end of the air pump. The moving component includes two moving rear wheels and one moving front wheel. The two moving rear wheels are installed in parallel, and a locking component is provided on the moving front wheel.

[0022] By adopting the above technical solution, the air pump is used to inflate the transport vehicle. When the transport vehicle breaks down halfway and needs on-site repair, the air pump needs to be moved at this time. The moving component is set to effectively move the air pump.

[0023] Preferably, the locking component includes a pushing member and a friction block. The friction block is installed on the pushing member. The friction block semi-surrounds the moving front wheel, and the pushing member drives the friction block to move closer to or away from the moving front wheel.

[0024] By adopting the above technical solution, the friction block is set to effectively fix the moved air pump and prevent the air pump from shifting during the working process.

[0025] Preferably, the pushing member includes a rotating piece and a connecting rod. The rotating piece is installed on the central axis of the moving front wheel. The rotating piece can rotate relative to the moving front wheel. The friction block is connected to the rotating piece through the connecting rod, and the rotating piece is provided with a hole for installing the connecting rod.

[0026] By adopting the above technical solution, during the rotation of the rotating piece, the connecting rod is driven to rotate, so that the friction block approaches the moving front wheel, achieving the effect of fixing the air pump.

[0027] In summary, the utility model has the following beneficial technical effects:

[0028] 1. Connect a liquid pump. After opening the first switch valve, the liquid flows into the liquid pump. The spaces of the air pump and the liquid pump are still closed. Most of the liquid pump is filled with liquid and there is very little air. Only a small part of the pressure in the air pump is lost and enters the liquid pump. Close the first switch valve. The pressure in the air pump is still higher than the atmospheric pressure. At this time, only need to remove the liquid pump, turn it upward, release a small amount of gas inside, and then pour out the liquid. After reducing the pressure of the liquid pump, the danger of pouring water is avoided, and there is no need to reduce the pressure in the air pump and then drain the water, effectively avoiding excessive power consumption for subsequent inflation of the air pump;

[0029] 2. If the pressure in the air pump is too high, the third switch valve can be opened to release some gas and then operate, effectively ensuring the safety of the staff;

[0030] 3. First, open the second switch valve to allow some gas to flow into the liquid pump, and then open the first switch valve. The liquid flows in, and the gas in the liquid pump is squeezed into the air pump again. At this time, the liquid flows in. Since the pressure between the liquid pump and the air pump is the same, there will be no excessive impact when the liquid flows down, effectively avoiding the danger caused by excessive impact.

[0037] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0038] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation to the present utility model.

[0039] An embodiment of the present utility model discloses a water discharging device for a tire inflator of a transport vehicle. Referring to Figure 1 , it includes an air pump 1 and a liquid pump 2;

[0040] A diversion pipe 3 is connected between the air pump 1 and the liquid pump 2. One end of the diversion pipe 3 is installed at the lowermost end of the air pump 1, and the other end is connected to the liquid pump 2. A first switch valve 4 is arranged on the diversion pipe 3, and the connection between the liquid pump 2 and the diversion pipe 3 is detachable.

[0041] After opening the first switch valve 4, the liquid will flow into the liquid pump 2 from the diversion pipe 3. The spaces of the air pump 1 and the liquid pump 2 are still closed. Most of the liquid pump 2 is liquid, and a small amount of air will also enter. The pressure in the air pump 1 is evenly dispersed to a part in the liquid pump 2, but only a small part of the loss enters the liquid pump 2. After closing the first switch valve 4, the pressure in the air pump 1 is still higher than the atmospheric pressure. At this time, only the liquid pump 2 needs to be removed, turned upward, and a small amount of gas inside is released, and then the liquid is poured out. After reducing the pressure of the liquid pump 2, the danger of pouring water is avoided, and there is no need to reduce the pressure in the air pump 1 before draining water, effectively avoiding excessive power consumption for subsequent inflation of the air pump 1.

[0042] One end of the air pump 1 is also connected to an air guide pipe 5. The air guide pipe 5 is connected to the liquid pump 2. A pressure balance pipe 6 is arranged on one side of the air guide pipe 5, and the pressure balance pipe 6 is communicated with the outside atmosphere. A second switch valve 7 is arranged on the air guide pipe 5, and a third switch valve 8 is arranged on the pressure balance pipe 6.

[0043] Since the pressure in the air pump 1 is relatively high, when the air pressure is too high, the liquid in the air pump 1 will instantaneously flow into the liquid pump 2. To avoid the excessive impact of the liquid in the air pump 1 instantaneously flowing into the liquid pump 2, an air guide pipe 5 is connected between the air pump 1 and the liquid pump 2. First, the second switch valve 7 is opened to allow part of the gas to flow into the liquid pump 2. After the pressure in the air pump 1 and the liquid pump 2 is balanced, the first switch valve 4 is opened, and the liquid flows into the liquid pump 2, squeezing the gas in the liquid pump 2 into the air pump 1. At this time, when the liquid flows in, since the pressure between the liquid pump 2 and the air pump 1 is the same, the downward flow of the liquid will not have too much impact, effectively avoiding the danger caused by excessive impact.

[0044] In addition, if the pressure in the air pump 1 is too high, the third switch valve 8 can be opened to release some gas before proceeding with the operation, effectively ensuring the safety of the staff.

[0045] A compression motor 9 is installed on the air pump 1, and a power protector 10 is installed on one side of the compression motor 9. The compression motor 9 compresses the gas. Additionally, the power protector 10 is provided to prevent the compression motor 9 from being damaged due to unstable power supply.

[0046] An air filter 11 is installed on the air pump 1, and multiple filter elements are arranged inside the air filter 11. There is a lot of dust in the air. By setting the air filter 11, the dust entering the air pump 1 is effectively reduced, and only air enters.

[0047] A fixed installation net 12 is provided on the air pump 1, and both the compression motor 9 and the air filter 11 are installed on the fixed installation net 12. Both the compression motor 9 and the air filter 11 need to be fixed, while the air pump 1 needs to ensure the integrity of its shell as much as possible. Therefore, as few bolts and welded parts are set as possible. By setting the fixed installation net 12, it can effectively ensure that as few parts as possible are installed on the air pump 1.

[0048] Refer to Figure 2 and Figure 3 A pressure gauge panel 13 is provided on the air pump 1, and the pressure gauge panel 13 is used to detect the pressure value inside the air pump 1. By installing the pressure gauge panel 13, the pressure value can be checked at any time, effectively avoiding the pressure value in the air pump 1 from being too high.

[0049] An air pressure controller 14 is provided on the air pump 1. One end of the air pressure controller 14 is provided with an air outlet 15. The air pressure controller 14 is connected to the pressure gauge panel 13. The air pressure controller 14 controls the opening and closing of the air outlet 15 according to the pressure value. Automatically controlling the opening and closing of the air outlet 15 according to the pressure value effectively avoids dangerous situations when the staff cannot see.

[0050] A moving component is provided at the lower end of the air pump 1. The moving component includes two moving rear wheels 16 and one moving front wheel 17. The two moving rear wheels 16 are installed in parallel, and a locking component is provided on the moving front wheel 17. The air pump 1 is used to inflate the transport vehicle. When the transport vehicle breaks down halfway and needs on-site repair, the air pump 1 needs to be moved at this time. By setting the moving component, the air pump 1 can be effectively moved.

[0051] Refer to Figure 4 and Figure 5, the locking assembly includes a pushing member and a friction block 19. The friction block 19 is mounted on the pushing member. The friction block 19 semi-surrounds the moving front wheel 17, and the pushing member drives the friction block 19 to move closer to or away from the moving front wheel 17. The pushing member includes a rotating plate 20 and a connecting rod 18. The rotating plate 20 is mounted on the axis of the moving front wheel 17. The rotating plate 20 is rotatable relative to the moving front wheel 17. The friction block 19 is connected to the rotating plate 20 through the connecting rod 18. The rotating plate 20 is provided with a hole for mounting the connecting rod 18.

[0052] The friction block 19 is provided to effectively fix the air pump 1 after movement and prevent the air pump 1 from shifting during operation. During the rotation of the rotating plate 20, the connecting rod 18 is driven to rotate, so that the friction block 19 approaches the moving front wheel 17, achieving the function of fixing the air pump 1.

[0053] The implementation principle of the water discharge device of the tire inflator 1 for a transport vehicle in an embodiment of the present invention is as follows: After opening the first switching valve 4, the liquid will flow into the liquid pump 2 from the diversion pipe 3. The spaces of the air pump 1 and the liquid pump 2 are still closed. Most of the liquid pump 2 is filled with liquid, and a small amount of air also enters. The pressure in the air pump 1 is evenly distributed to a part of the liquid pump 2, but only a small part is lost and enters the liquid pump 2. After closing the first switching valve 4, the pressure in the air pump 1 is still higher than the atmospheric pressure. At this time, only the liquid pump 2 needs to be removed, turned upward, a small amount of gas inside is released, and then the liquid is poured out. After reducing the pressure of the liquid pump 2, the danger of pouring water is avoided, and there is no need to reduce the pressure in the air pump 1 before discharging water, effectively avoiding excessive power consumption for subsequent inflation of the air pump 1.

[0054] The above are all the preferred embodiments of the present invention, and the protection scope of the present invention is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
