Description

Technical Field

[0001] This application relates to the field of battery fluid replenishment technology, and in particular to a fluid injection device for train batteries. Background Technology

[0002] Railway batteries are an important component of trains, and the quality of battery maintenance and repair plays a crucial role in the safe operation of trains. Therefore, it is important to focus on optimizing battery maintenance and personnel management to improve battery life and safety, reduce the maintenance cost of battery packs, and at the same time reduce the risks and labor intensity caused by manual operation.

[0003] Most commonly used storage batteries employ vent plugs, requiring manual disassembly and measurement of the water level during battery maintenance before adding water. Controlling the amount of water added necessitates visual observation, which is particularly problematic during centralized water addition of battery banks. Inconsistent water levels inevitably lead to variations in individual battery performance, and the uncertainty of water addition cycles after a period of battery use further complicates the maintenance process. This results in unclear fluid level observation, difficult operation, and is time-consuming and labor-intensive, increasing maintenance costs. The inconvenience of observation is a primary issue that needs to be addressed. Furthermore, given that this involves adding water to railway batteries, safety must be paramount. Therefore, highly electrified equipment should be avoided as much as possible, as it can generate electrical sparks and pose safety hazards. Consequently, non-electrified technical solutions are widely favored in this field.

[0004] Therefore, existing technologies still need to be improved and enhanced.

[0005] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solutions of this application and facilitating understanding by those skilled in the art. It should not be assumed that these technical solutions are known to those skilled in the art simply because they have been described in the background section of this application. Utility Model Content

[0006] In order to solve one or more of the above-mentioned technical problems, such as the complexity of the battery pack water replenishment and maintenance process, especially the unclear, inconvenient or unsafe liquid level observation, this disclosure provides a liquid injection device for train batteries, which aims to effectively and safely solve the above-mentioned problems.

[0007] In a first aspect of this disclosure, a liquid injection device for a train battery is provided, comprising a device body and a connecting rod. The upper part of the device body is provided with a liquid inlet, and the interior of the device body is provided with a vertically penetrating guide groove. The lower part of the device body is provided with a bottom opening of the guide groove. The connecting rod is disposed within the guide groove, and its lower end extends from the bottom opening of the guide groove. The upper part of the device body is also provided with a main body cover covering the entire top of the device body. A liquid level monitoring mechanism is provided on the upper surface of the main body cover. The main body cover and the liquid level monitoring mechanism are made of a light-transmitting material. A liquid level determining mechanism is provided at the lower end of the connecting rod, and the upper end of the connecting rod is positioned facing the liquid level monitoring mechanism. The lower part of the liquid level monitoring mechanism is configured as a downward-opening cavity structure, the edge of the opening of the cavity structure being sealed to the upper surface of the main body cover. The cavity structure of the liquid level monitoring mechanism communicates with the guide groove and is configured to accommodate the upper end of the connecting rod extending into it.

[0008] Furthermore, in some embodiments, a reflective prism structure is provided between the inner and outer surfaces of the sidewall of the cavity structure and at the lower part of the liquid level monitoring mechanism near the opening of the cavity structure. The reflective surface of the reflective prism structure is arranged to face the central axis of the cavity structure and at a 45-degree angle to the horizontal plane.

[0009] Furthermore, in some embodiments, the liquid level monitoring mechanism is also provided with a monitoring cover, which is configured to cover the top of the cavity structure of the liquid level monitoring mechanism.

[0010] Furthermore, in some embodiments, the monitoring cover is coated with an opaque coating that covers the central portion of the cavity structure, the central portion of which refers to the area from the central axis of the cavity structure to the sidewall.

[0011] Furthermore, in some embodiments, the side of the monitoring cover facing the cavity structure is provided with an inverted conical structure, and the tip of the inverted conical structure faces the interior of the cavity structure.

[0012] Furthermore, in some embodiments, the axis through which the tip of the inverted cone structure passes coincides with the central axis of the monitoring cover, and the bottom of the inverted cone structure covers the central portion of the monitoring cover, wherein the central portion of the monitoring cover refers to the area from the central axis of the monitoring cover to the sidewall of the cavity structure.

[0013] Furthermore, in some embodiments, a color-developing segment is provided at the end of the connecting rod facing the liquid level monitoring mechanism.

[0014] Furthermore, in some embodiments, the liquid level determining mechanism described above is configured as a float.

[0015] Furthermore, in some embodiments, the aforementioned inlet nozzle is configured to be fixed to the upper part of the device body via a connecting ring.

[0016] Furthermore, in some embodiments, the main body of the device is provided with a lower chamber and an upper chamber, the lower chamber is configured to communicate with the liquid inlet, the lower chamber is configured to communicate with the upper chamber through a connecting rod stop valve, and the upper chamber is configured to communicate with the guide groove.

[0017] The beneficial effects of this disclosure are at least as follows:

[0018] 1) In some embodiments, by providing a liquid level monitoring mechanism on the upper surface of the main body cover, and by making the main body cover and the liquid level monitoring mechanism made of light-transmitting material, it is convenient to observe the rise of the internal connecting rod of the liquid injection device from the top surface of the main body, so as to promptly confirm whether the liquid level has reached the preset height. Furthermore, in a preferred embodiment, a reflective prism structure is provided between the inner and outer surfaces of the sidewall of the cavity structure of the liquid level monitoring mechanism, and at the lower part of the liquid level monitoring mechanism near the opening of the cavity structure. The reflective surface of the reflective prism structure is positioned facing the central axis of the cavity structure and at a 45-degree angle to the horizontal plane. Thus, when the connecting rod enters the cavity structure and reaches or exceeds the preset bottom position (horizontal position) of the reflective prism structure, the connecting rod can transmit light to the top monitoring cover via the reflective surface of the reflective prism structure, and this light can be transmitted to the operator monitoring from directly above via the light-transmitting monitoring cover. Conversely, if the connecting rod does not enter the preset position (horizontal position) of the cavity structure, then the connecting rod cannot be seen from directly above the monitoring cover. Therefore, by means of light refraction and reflection, rather than electromagnetic means, it is safe and reliable to know whether the liquid level has reached the preset horizontal height position.

[0019] 2) Further, in some embodiments, an inverted conical structure is provided on the side of the monitoring cover facing the cavity structure, with the tip of the inverted conical structure facing the interior of the cavity structure; thus, since the light from the top of the connecting rod pointing vertically upward will be reflected or refracted by the conical surface of the inverted conical structure and cannot reach vertically upward and be seen by the observer directly above; under this setting, the connecting rod cannot be observed directly above when it has not reached the preset height, and can only be observed from directly above the side wall when the connecting rod rises to the horizontal height position of the aforementioned preset reflecting prism structure in the side wall (presenting a ring, rather than an enlarged circle), avoiding visual fatigue or differences in vision among different personnel that prevent the monitoring of the connecting rod position from being completed. Preferably, in some embodiments, the axis through which the tip of the inverted conical structure passes coincides with the central axis of the monitoring cover, and generally also coincides with the central axis of the connecting rod. Furthermore, the bottom of the inverted conical structure covers the central portion of the monitoring cover, which refers to the area from the central axis of the monitoring cover to the side wall of the cavity structure. This ensures that the top of the connecting rod cannot be observed directly from above, but can only be observed (i.e., appearing as a ring) from the area from the central axis of the monitoring cover to the side wall of the cavity structure when the connecting rod reaches a preset height (the horizontal height of the reflective mirror surface of the reflective prism structure entering the cavity structure).

[0033] In order to solve at least one of the above-mentioned problems, as well as one or more other potential problems, an exemplary embodiment of this disclosure provides a liquid injection device for a train battery, which generally injects or adds distilled water or purified water.

[0034] The following description, in conjunction with the accompanying drawings and embodiments, provides further explanation.

[0035] Figure 1A diagram is shown of a liquid injection device for a train battery according to an embodiment of the present disclosure. In the illustrated embodiment, the liquid injection device 100 for a train battery includes a device body 30, an inlet 60 provided on the upper part of the device body 30, a body cover 40 covering the entire top of the device body 30, a liquid level monitoring mechanism 50 provided on the upper surface of the body cover 40, and both the body cover 40 and the liquid level monitoring mechanism 50 being made of a light-transmitting material; a liquid level determining mechanism 90 is provided at the lower end of a connecting rod 20, and the upper end of the connecting rod 20 is positioned facing the liquid level monitoring mechanism 50. It should be understood that providing a liquid level monitoring mechanism on the upper surface of the body cover, and making the body cover and the liquid level monitoring mechanism made of a light-transmitting material, facilitates observation of the rising of the connecting rod inside the liquid injection device from the top surface of the body, so as to promptly confirm whether the liquid level has reached a preset height.

[0036] Furthermore, in order to illustrate in more detail the interior of the liquid injection device for train batteries in the embodiments of this disclosure, the following description is provided in conjunction with the accompanying drawings.

[0037] Figure 2 A cross-sectional view of a liquid injection device for a train battery according to an embodiment of the present disclosure is shown. In the illustrated embodiment, the liquid injection device 100 for a train battery includes a device body 30 and a connecting rod 20; a vertically penetrating guide groove 10 is provided inside the device body 30, and a bottom opening of the guide groove 10 is provided at the lower part of the device body 30; the connecting rod 20 is disposed within the guide groove 10, and its lower end extends out from the bottom opening of the guide groove 10; the lower part of the liquid level monitoring mechanism 50 is provided as a downward-opening cavity structure 50-1, the edge of the opening of the cavity structure 50-1 is sealed to the upper surface of the main body cover 40, the cavity structure 50-1 of the liquid level monitoring mechanism 50 communicates with the guide groove 10 and is configured to accommodate the upper end of the connecting rod 20 extending into it. Further, the liquid level monitoring mechanism 50 is also provided with a monitoring cover, which is configured to cover the top of the cavity structure of the liquid level monitoring mechanism. Alternatively, in some embodiments, the monitoring cover is coated with an opaque coating that covers the central portion of the cavity structure 50-1, which refers to the area from the central axis of the cavity structure 50-1 to the sidewall. It should be understood that, to facilitate observation of the connecting rod from the level monitoring mechanism 50, a color-developing section is provided at the end of the connecting rod 20 facing the level monitoring mechanism 50, so that the position of the connecting rod can be roughly observed from the light-transmitting main cover 40 and the level monitoring mechanism 50.

[0038] Furthermore, to further illustrate the internal structure of the liquid injection device, the following explanation will be provided in conjunction with the accompanying drawings.

[0039] Figure 3aAnother cross-sectional view of a liquid injection device for a train battery according to an embodiment of the present disclosure is shown. In the illustrated embodiment, the device body 30 is provided with a lower chamber 30-2 and an upper chamber 30-4. The lower chamber 30-2 is configured to communicate with a liquid inlet (not shown) and is configured to communicate with the upper chamber 30-4 via a connecting rod stop valve 30-5. The upper chamber 30-4 is configured to communicate with a guide groove 10. It should be understood that the inlet nozzle (not shown) is preferably configured as a three-way pipe, wherein the two horizontal pipes shown in the figure can connect multiple liquid injection devices in series, thereby simultaneously replenishing water to multiple liquid injection devices (corresponding batteries) in series; and the lower path of the three-way pipe is connected to the lower chamber 30-2 of the device body 30 for replenishing water (or other liquids that can replace water). In the illustrated embodiment, a crossbeam section is cleverly provided on the connecting rod to fix and connect the illustrated connecting rod stop valve 30-5, and the lower end of the connecting rod stop valve 30-5 is provided with With a water-stop spherical structure, it can be understood that as the liquid level rises, the liquid level determining mechanism (not shown) actuates the connecting rod 20, lifting it up. Consequently, the connecting rod water-stop valve 30-5 is also lifted. When a preset height (horizontal liquid level) is reached, the water-stop spherical structure of the connecting rod water-stop valve 30-5 precisely seals the communication channel between the lower chamber 30-2 and the upper chamber 30-4, thus preventing water from entering the upper chamber 30-4 from the lower chamber 30-2. Due to the structure of the connecting rod water-stop valve 30-5, external water replenishment first enters the lower chamber 30-2, not the upper chamber 30-4. After water enters the upper chamber 30-4, it can flow downwards through the gap between the connecting rod 20 and the device body 30 (or through a special opening on the device body 30), specifically, it can flow downwards along the surface of the connecting rod 20 and enter the battery being replenished. The liquid level determining mechanism (not shown) is preferably a float that can move up and down with the battery liquid level. Furthermore, Figure 3b It shows Figure 3a A magnified view of the indicator section.

[0040] Furthermore, the following section provides a detailed explanation of liquid level monitoring institutions.

[0041] Figure 4a , 4b Figures 5a and 5b show views of the liquid level monitoring mechanism as seen from above the top according to an embodiment of the present disclosure. Figure 4a In the middle, the connecting rod 20 has not yet entered the preset height and is still below the cavity structure 50-1 of the liquid level monitoring mechanism 50. From the right half of the schematic diagram (that is, from the top view of the liquid level monitoring mechanism 50), the connecting rod 20 cannot be seen. Generally, it may appear as a completely dark circle (see...). Figure 4b (As shown). And... Figure 5aIn the diagram, connecting rod 20 has reached the preset height and is positioned within the cavity structure 50-1 of the liquid level monitoring mechanism 50, exceeding the height of the reflective mirror surface of the reflective prism structure 50-3. From the right half of the schematic diagram (i.e., from a top-down view of the top of the liquid level monitoring mechanism 50), a circular image, typically colored like the connecting rod, can be seen (see...). Figure 5b(As shown). In some embodiments, a reflective prism structure 50-3 is provided between the inner and outer surfaces of the sidewall of the cavity structure 50-1, and at the lower part of the liquid level monitoring mechanism 50 near the opening of the cavity structure 50-1. The reflective surface of the reflective prism structure 50-3 is positioned facing the central axis of the cavity structure 50-1 and at a 45-degree angle to the horizontal plane. Thus, when the connecting rod enters the cavity structure and reaches and exceeds the preset bottom position (horizontal position) of the reflective prism structure, the connecting rod can transmit light to the top monitoring cover through the reflective surface of the reflective prism structure, and the light can be transmitted to the operator monitoring from directly above via the light-transmitting monitoring cover. Conversely, if the connecting rod does not enter the preset position (horizontal position) of the cavity structure, then the connecting rod cannot be seen from the sidewall of the cavity structure when viewed from directly above the monitoring cover. Thus, by means of light refraction and reflection, rather than electromagnetic means, it is safe and reliable to know whether the liquid level has reached the preset horizontal height position. In other embodiments, the monitoring cover is coated with an opaque coating that covers the central portion of the cavity structure 50-1, which refers to the area from the central axis of the cavity structure 50-1 to the sidewall. Further, in some embodiments, the monitoring cover has an inverted conical structure on the side facing the cavity structure 50-1, with the tip of the inverted conical structure facing the interior of the cavity structure 50-1. Therefore, since light rays from the top of the connecting rod pointing vertically upwards will be reflected or refracted by the conical surface of the inverted conical structure and cannot reach vertically upwards to be seen by the observer directly above, this arrangement prevents the connecting rod from being observed directly above when it has not reached a preset height. It only becomes visible from directly above the sidewall (presenting a ring shape, not an enlarged circle) when the connecting rod rises to the horizontal height of the aforementioned preset reflecting prism structure in the sidewall, thus avoiding visual fatigue or differences in vision among different personnel that could prevent the monitoring of the connecting rod's position. More preferably, the axis through which the tip of the inverted conical structure passes coincides with the central axis of the monitoring cover, and the bottom of the inverted conical structure covers the central portion of the monitoring cover, which refers to the area from the central axis of the monitoring cover to the side wall of the cavity structure 50-1. This ensures that the top of the connecting rod cannot be directly observed from above, but only when the connecting rod reaches a preset height (the horizontal height of the reflecting mirror surface of the reflecting prism structure entering the cavity structure) can the connecting rod be observed from the area from the central axis of the monitoring cover to the side wall of the cavity structure (i.e., appearing as a ring). Of course, to make the connecting rod 20 more clearly visible, a color-developing section is provided at the end of the connecting rod 20 facing the liquid level monitoring mechanism 50. Furthermore, it should be understood that when the liquid level drops again, as the connecting rod 20 descends, the attached... Figure 5b The situation will also revert to the attached Figure 4b The situation, subsequently, attached Figure 5b The circular image in the image will disappear and will revert to its original state. Figure 4b The image in the image.

Additionally, in this illustrated embodiment, a connecting rod 20, a connecting rod stop valve 30-5, a body seat washer 30-8-1, a lower cover 30-9, a body upper cover 40, a liquid level monitoring mechanism 50, and a liquid level determination mechanism 90 are also shown; the illustration of these components is intended to more fully disclose the liquid injection device 100 for a train battery and to suggest an easy assembly approach for those skilled in the art.
