[0037] The utility model discloses a drainage box structure, which saves space waste and facilitates layout.
[0038] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0039] like Figure 1 As shown, the embodiment of the utility model provides a drainage box structure, including a box body 1, a first connecting pipe 2, a second connecting pipe 3, a drainage pipe 4 and an exhaust assembly. The box body 1 has an inner cavity; the first end of the first connecting pipe 2 is connected to the inner cavity of the box body 1, and the second end of the first connecting pipe 2 is used to communicate with the drainage outlet of the air conditioner; the first end of the second connecting pipe 3 is connected to the inner cavity of the box body 1, and the second end of the second connecting pipe 3 is used to communicate with the drainage outlet of the fuel cell; the drainage pipe 4 is connected to the inner cavity of the box body 1 and is used to discharge the drainage in the inner cavity; the exhaust assembly is connected to the inner cavity of the box body 1 and is used to discharge the gas in the inner cavity.
[0040] The drainage box structure provided by the embodiment of the utility model introduces the drainage discharged from the drainage outlet of the air conditioner into the inner cavity of the box body 1 through the first connecting pipe 2, and introduces the water vapor discharged from the drainage outlet of the fuel cell into the inner cavity of the box body 1 through the second connecting pipe 3, and discharges the drainage in the inner cavity of the box body 1 through the drainage pipe 4, and discharges the gas in the inner cavity of the box body 1 through the exhaust assembly. Through the above arrangement, the air conditioner and the fuel cell can share the same drainage box structure, avoiding the need to set up a drainage box for the air conditioner and a drainage box for the fuel cell separately, thereby reducing the number of components, thereby achieving the effect of saving space and facilitating the overall layout.
[0041] In addition, the water vapor at the drainage outlet of the fuel cell enters the inner cavity of the box body 1 and is diverted. The drainage of the fuel cell flows out through the drainage pipe 4, and the gas exhausted by the fuel cell is discharged by the exhaust assembly, so as to avoid setting up a thicker drainage pipe to discharge the water vapor exhausted by the fuel cell together, reduce the size of a single pipe, and facilitate layout.
[0042] It should be noted that the size of the box body 1 and its inner cavity can be determined according to actual needs. In the present embodiment, the box body 1 is a square box body, and its length, width and height are all greater than the diameter of the pipe (including the first connecting pipe 2, the second connecting pipe 3 and the drainage pipe 4). The size of the box body 1 and its inner cavity can also be reduced to only meet the drainage and exhaust requirements. For example, the first connecting pipe 2, the second connecting pipe 3 and the drainage pipe 4 intersect, and the intersection is the box body 1. The size of the box body 1 is not greater than the diameter of the pipe, and the connecting area at the intersection is the inner cavity of the box body 1.
[0043] It can be understood that the gas exhausted by the fuel cell may include gas generated by the fuel cell power generation and gas that has not been completely reacted.
[0044] In order to reduce the mutual interference between the air conditioning drainage and the fuel cell drainage, the box body 1 has two relatively independent inlets connected to the inner cavity, and the two inlets are respectively connected to the first connecting pipe 2 and the second connecting pipe 3. That is, the drainage discharged from the drainage outlet of the air conditioner passes through the first connecting pipe 2 and enters the inner cavity of the box body 1 through one inlet of the box body 1, and the water vapor discharged from the drainage outlet of the fuel cell passes through the second connecting pipe 3 and enters the inner cavity of the box body 1 through the other inlet of the box body 1. Since the two inlets are relatively independent, the drainage of the air conditioner and the drainage of the fuel cell flowing into the inner cavity of the box body 1 will not interfere with each other, so that they can flow smoothly into the inner cavity of the box body 1.
[0045] Of course, only one inlet may be provided, and the first connecting pipe 2 and the second connecting pipe 3 are both connected to the same inlet.
[0046] For the convenience of arrangement, the first connecting pipe 2 and the second connecting pipe 3 are symmetrically arranged on both sides of the box body 1. That is, the first connecting pipe 2, the box body 1 and the second connecting pipe 3 can also be arranged in one direction, so that the operator can operate the connection of the first connecting pipe 2 and the second connecting pipe 3 facing the side perpendicular to the direction, so as to complete the connection between the first connecting pipe 2 and the drainage outlet of the air conditioner and the connection between the second connecting pipe 3 and the drainage outlet of the fuel cell without changing the direction of the operator.
[0047] In this embodiment, the box body 1 is a rectangular structure, and the first connecting pipe 2 and the second connecting pipe 3 are respectively arranged on two symmetrical surfaces of the box body 1 .
[0048] The first connecting pipe 2 and the second connecting pipe 3 may also be symmetrically arranged on the same surface or two adjacent surfaces of the box body 1 .
[0049] In order to facilitate drainage, the box body 1 has an outlet penetrating its bottom surface and communicating with the inner cavity, the first end of the drainage pipe 4 is connected to the outlet, and the second end of the drainage pipe 4 is a drainage outlet end for draining drainage; during the use of the drainage box structure, the horizontal position of the first end of the drainage pipe 4 is higher than the horizontal position of the second end of the drainage pipe 4. That is, during the correct installation and use of the drainage box structure, the drainage in the inner cavity of the box body 1 can flow from the first end of the drainage pipe 4 to the second end (drainage outlet end) of the drainage pipe 4, and be discharged from the drainage box structure by the second end (drainage outlet end) of the drainage pipe 4.
[0050] Since the outlet is located at the bottom surface of the box body 1, it can ensure that the drainage in the inner cavity of the box body 1 can be discharged in time and completely. Of course, the outlet can also be arranged on the side of the box body 1.
[0051] The second end of the drainage pipe 4 may also be made higher than the first end of the drainage pipe 4 , and drainage in the inner cavity of the box body 1 may be discharged through the drainage pipe 4 by providing drainage power equipment (such as a water pump, etc.).
[0052] In order to further simplify the structure, the second end of the drainage pipe 4 is connected to the outside. When the drainage box structure provided in this embodiment is applied to a vehicle, the second end of the drainage pipe 4 can be arranged under the vehicle so that the drainage can be discharged to the ground through the second end (drainage outlet end) of the drainage pipe 4.
[0053] In this embodiment, the exhaust assembly includes an exhaust pipe 5, the first end of the exhaust pipe 5 is connected to the inner cavity of the box body 1, and the second end of the exhaust pipe 5 is a gas outlet end for exhausting gas; when the drainage box structure is in use, the horizontal position of the first end of the exhaust pipe 5 is lower than the horizontal position of the second end of the exhaust pipe 5. Through the above arrangement, the gas can flow in the exhaust pipe 5 along the arrangement direction from the first end of the exhaust pipe 5 to the second end of the exhaust pipe 5, and finally be discharged from the second end of the exhaust pipe 5 (gas outlet end).
[0054] Furthermore, by adjusting the structure of the exhaust pipe 5 and thus adjusting the position of the second end (gas outlet end) of the exhaust pipe 5, the exhaust of the drainage box structure will not interfere with other components. Of course, the exhaust assembly can also be provided with exhaust holes on the top or side of the box body 1, which can also achieve the exhaust effect.
[0055] Furthermore, the gas outlet is arranged upward. In order to prevent external impurities from entering the inner cavity of the box body 1 from the gas outlet, the drainage box structure further includes a cover body 6 which is arranged on the gas outlet, and the positive projection of the cover body 6 to the gas outlet covers the gas outlet, and an exhaust structure 51 for gas exhaust is formed between the cover body 6 and the gas outlet. Through the above arrangement, dust and foreign matter are effectively prevented from entering the inner cavity of the box body 1, and the workload of inspection and maintenance is reduced.
[0056] In the embodiment of the utility model, the exhaust structure 51 can be a hollow structure arranged near the second end (gas outlet end) of the exhaust pipe 5. When the second end of the exhaust pipe 5 is directly connected to the cover body 6, the gas flowing to the second end of the exhaust pipe 5 can be discharged by the exhaust structure 51.
[0057] The exhaust structure 51 may be an exhaust hole.
[0058] The second end (gas outlet end) of the exhaust pipe 5 and the cover body 6 can also be connected by a connecting support. Under the supporting action of the connecting support, a circumferential gap is formed between the second end of the exhaust pipe 5 and the cover body 6, and the area of the circumferential gap that is not blocked by the connecting support is the exhaust structure 51, so that the gas can be discharged from the exhaust structure 51.
[0059] Preferably, the cover body 6 is a conical cover body. A fan-shaped sheet structure can be used to connect the edges of two radii to form a conical shell, that is, the cover body 6; or a plurality of identical isosceles trapezoids can be sequentially spliced to form a pyramid shell, that is, the cover body 6. That is, the structure of the conical cover body is that its small end is a closed tip, and its large end is a circular or polygonal opening structure. That is, the cover body 6 can be an umbrella cap structure.
[0060] The small end of the conical cover faces away from the gas outlet, and the large end of the conical cover faces the gas outlet. External dust and impurities can slide along the outer side of the conical cover and fall from the edge of its large end, effectively preventing external impurities from falling into the gas outlet.
[0061] Specifically, the box body 1 can be made of stainless steel, and the first connecting pipe 2, the second connecting pipe 3 and the drainage pipe 4 can be steel pipes. The position where the first connecting pipe 2, the second connecting pipe 3 and the drainage pipe 4 are connected to the box body 1 can adopt a stainless steel welding structure, and then be transferred to the hard pipe (outlet pipe of the drainage outlet) on the equipment (air conditioner and fuel cell) through a hose.
[0062] During the assembly process of the exhaust component and the box body 1, the exhaust pipe 5 (steel pipe) is first welded to the upper part of the box body 1, and the second end of the exhaust pipe 5 is welded to the connecting support (such as a stainless steel column, etc.), and then the cover body 6 is welded to the connecting support. Under the support of the connecting support, an exhaust structure 51 is formed between the exhaust pipe 5 and the cover body 6.
[0063] The sizes of the inlet of the box body 1 (the interface connected to the first connecting pipe 2 and the second connecting pipe 3) and the outlet of the box body 1 (the interface connected to the drainage pipe 4) can be calculated based on the maximum drainage volume of the air conditioner and the fuel cell that need to be connected to the drainage box structure, and pipes of suitable diameters (the first connecting pipe 2, the second connecting pipe 3 and the drainage pipe 4) are selected to avoid the situation where the drainage in the inner cavity of the box body 1 overflows due to excessive drainage volume and cannot be discharged in time.
[0064] The embodiment of the utility model provides a vehicle, including an air conditioner and a fuel cell, and also includes any of the above-mentioned drainage box structures, wherein the drainage outlet of the air conditioner is connected to the first end of the first connecting pipe 2 of the drainage box structure; the drainage outlet of the fuel cell is connected to the first end of the second connecting pipe 3 of the drainage box structure.
[0065] Since the above-mentioned drainage box structure has the above-mentioned technical effects, the vehicle having the above-mentioned drainage box structure should also have the same technical effects, which will not be described in detail here.
[0066] Among them, the above-mentioned vehicles can be automobiles (including fuel vehicles, gas vehicles and electric vehicles, etc.), and the above-mentioned vehicles can also be rail vehicles (such as hydrogen energy rail vehicles, etc.). No specific restrictions are made here and they are all within the scope of protection.
[0067] Furthermore, the drainage box structure is located between the air conditioner and the fuel cell. Through the above arrangement, the total amount of the connecting pipes connecting the drainage outlet of the air conditioner to the drainage box structure and the connecting pipes connecting the drainage outlet of the fuel cell to the drainage box structure is effectively shortened, and the travel of the drainage of the air conditioner from the drainage outlet of the air conditioner to the drainage box structure and the travel of the drainage and exhaust of the fuel cell from the drainage outlet of the fuel cell to the drainage box structure are optimized, which facilitates the smooth flow of fluid (drainage and exhaust).
[0068] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
[0069] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
