Water tank leak-proof structure

Abstract

This utility model discloses a water tank leak-proof structure, including a tank body. The tank body is equipped with an injection pipe, an outlet pipe, and a return pipe. The injection pipe is located at the upper part of the tank body. A partition is fixed inside the tank body below the injection pipe, dividing the interior of the tank body into an upper space and a lower space. The partition consists of a baffle near the injection pipe and an upper clamping plate away from the injection pipe. A through hole is provided on the upper clamping plate connecting the upper and lower spaces, and a vertically placed mesh plate is provided at the through hole. By setting a partition below the injection pipe, the interior of the tank body is divided into an upper and lower space, effectively preventing coolant in the lower space from splashing into the upper space and the injection pipe. Furthermore, the mesh plate at the through hole of the upper clamping plate can disperse coolant that sloshes due to inertia, thereby suppressing the upward trend of the coolant.

Description

Technical Field

[0001] This utility model relates to the field of rail locomotive technology, and in particular to a water tank leak-proof structure. Background Technology

[0002] During operation, railway locomotives require coolant tanks to cool their power units. Conventional tanks are simply covered with a plate and sealed with sealant for protection. However, during actual locomotive operation, the average impact force during coupling and uncoupling can reach 6G, with a maximum of 19G. This instantaneous impact far exceeds the impact requirements of the IEC 61373 standard. Under this high-level instantaneous impact acceleration, the breather valve on the tank's injection pipe cannot promptly regulate the pressure inside the tank, causing the sealant on the tank cover to fail and leak air. Since the water pump connected to the tank is not running when the coupling is uncoupling, the coolant level is close to the injection pipe and the tank cover. The instantaneous impact causes the liquid to surge, leading to coolant leakage. Summary of the Invention

[0003] This utility model provides a water tank leak-proof structure to overcome the above-mentioned technical problems.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] A leak-proof structure for a water tank includes a tank body. The tank body is provided with an injection pipe, an outlet pipe, and a return pipe. The injection pipe is located at the upper part of the tank body. A partition is fixedly installed inside the tank body below the injection pipe. The partition divides the interior of the tank body into an upper space and a lower space. The partition is composed of a baffle near the injection pipe and an upper clamping plate away from the injection pipe. The upper clamping plate has a through hole connecting the upper space and the lower space. A vertically placed mesh plate is provided at the through hole.

[0006] Furthermore, it also includes a flow guide plate, which is vertically disposed on the upper clamping plate, with the top of the flow guide plate inclined toward the end of the upper clamping plate away from the injection tube.

[0007] Furthermore, the end of the baffle away from the upper clamping plate is inclined upward relative to the upper clamping plate.

[0008] Furthermore, the mesh plate is inclinedly disposed within the through hole.

[0009] Furthermore, a breather valve is provided on the injection tube.

[0010] Furthermore, it also includes a liquid level observation window, which is connected to the tank body.

[0011] Furthermore, a lower clamping plate is fixed inside the box, which is located below the upper clamping plate, and the lower clamping plate is provided with a through hole.

[0012] Furthermore, a nut is fixed to the top of the box.

[0013] Furthermore, it also includes a base, on which the housing is fixed, and bolt holes are provided.

[0014] Furthermore, the top of the mesh plate is provided with a connecting plate, the connecting plate has an elongated hole, and the connecting plate is fixed to the upper clamping plate by bolts in the elongated hole.

[0015] Beneficial effects: This utility model provides a leak-proof structure for a water tank. By installing a partition below the injection pipe, the interior of the tank is divided into an upper space and a lower space. The partition can effectively prevent coolant in the lower space from splashing into the upper space and the injection pipe. In addition, the mesh plate installed at the through hole of the upper clamping plate can disperse the coolant that shakes due to inertia, thereby suppressing the upward trend of the coolant.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0033] This embodiment provides a leak-proof structure for a water tank, such as Figures 1 to 4 As shown, the device includes a housing 1, on which an injection pipe 11, an outlet pipe 12, and a return pipe 13 are welded. The injection pipe 11 is located at the top of the housing 1 and is equipped with a breather valve. A partition is fixed inside the housing 1, located below the injection pipe 11, dividing the interior of the housing 1 into an upper space and a lower space. The partition consists of a baffle 2 near the injection pipe 11 and an upper clamping plate 3 away from the injection pipe 11. Figure 1 and Figure 2 As shown, the upper clamping plate 3 has a through hole connecting the upper space and the lower space, and a vertically placed mesh plate 4 is provided at the through hole.

[0034] This embodiment provides a water tank leak-proof structure. By installing a baffle below the injection pipe 11, the interior of the tank 1 is divided into an upper space and a lower space. The baffle can effectively prevent coolant in the lower space from splashing into the upper space and the injection pipe 11. In addition, the mesh plate 4 provided at the through hole of the upper clamping plate 3 can disperse the coolant that shakes due to inertia, thereby suppressing the upward trend of the coolant.

[0035] Preferably, such as Figures 1 to 3 As shown, it also includes a deflector plate 8, such as Figure 3As shown, the guide plate 8 is vertically arranged on the upper clamping plate 3. The top of the guide plate 8 is inclined towards the end of the upper clamping plate 3 away from the injection pipe 11. Even if a small amount of coolant enters the upper space from the through hole of the upper clamping plate 3, it will be blocked by the guide plate 8 and return to the lower space.

[0036] Preferably, such as Figure 3 As shown, the end of the baffle 2 away from the upper clamping plate 3 is inclined upward relative to the upper clamping plate 3. The resulting slope allows a small amount of coolant splashed onto the baffle to quickly flow into the through hole. At the same time, the slope allows coolant added from the injection pipe 11 to quickly flow into the lower space.

[0037] Preferably, such as Figure 4 As shown, the mesh plate 4 is inclinedly disposed in the through hole, so that the mesh plate 4 can function in two mutually perpendicular directions in the horizontal direction.

[0038] Specifically, a lower clamping plate 6 is also fixed inside the box body 1. The lower clamping plate 6 is located below the upper clamping plate 3, and the lower clamping plate 6 is provided with a through hole.

[0039] Preferably, such as Figures 1 to 3 As shown, it also includes a liquid level observation window 7. The two ends of the liquid level observation window 7 are respectively connected to the low liquid level end and the high liquid level end of the tank 1 to facilitate observation of the liquid level. When adding coolant from the injection pipe 11, the liquid level of the coolant should be higher than the lower clamping plate 6 and lower than the upper clamping plate 3.

[0040] Specifically, a nut is fixed to the top of the tank body 1, and the cover plate of the water tank is connected to the nut on the top of the tank body 1 by bolts. The gaps created after the connection are sealed with sealant.

[0041] Specifically, such as Figures 1 to 4 As shown, it also includes a base 5, the box 1 is fixed on the base 5, and the base 5 has bolt holes, which are used to fix it to the locomotive.

[0042] Preferably, the top of the mesh plate 4 is provided with a connecting plate 41, the connecting plate 41 is provided with an elongated hole, the connecting plate 41 is fixed to the upper clamping plate 3 by bolts in the elongated hole, and nuts for installing bolts are welded on the upper clamping plate 3. By providing the elongated hole, the angle of the mesh plate 4 can be adjusted.

[0043] Specifically, such as Figure 3 As shown, both the outlet pipe 12 and the return pipe 13 are equipped with flange plates to facilitate the connection of the outlet pipe 12 to the water pump and the return pipe 13 to the cooling pipeline.

[0044] Preferably, a pressure balance pipe 9 is welded onto the housing 1, and an angle valve is provided on the pressure balance pipe 9. By unscrewing the angle valve, the inside of the water tank is connected to the outside atmosphere, so that the coolant can be smoothly injected into the water tank.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
