Description

Technical Field

[0001] The invention relates to the technical field of storage batteries, in particular to an integrated intelligent water-adding device for batch storage batteries. Background Art

[0002] Replenishing water for daily use of batteries in railway passenger cars is a job that requires a high frequency and workload. In the past, water addition and liquid level control could only rely on manual feeling or shaking the battery to observe the liquid level height of the outermost battery. It was difficult to accurately control the liquid level and ensure that the liquid level of the entire battery group remained consistent. The water level was often too high or insufficient. If the filling level is too high, it is easy to cause electrolyte leakage and poor insulation of the vehicle body. If the filling level is too low or insufficient, it is easy to cause a decrease in battery capacity and even cause serious consequences such as battery overcharge, cracking, and explosion. In recent years, there have been many battery explosion accidents in the entire railway passenger car system. The previous operation mode was time-consuming and labor-intensive, and the technical standards and equipment safety could not be guaranteed. In order to learn from the lessons of the accident, the liquid level control of distilled water added to the battery has become a more important technical standard. At the same time, accurately controlling the battery liquid level is also a difficult point to tackle;

[0003] At present, Wuchang Passenger Vehicle Depot has 1,650 alkaline battery buses that need to be filled with water. According to the operation requirements, the batteries need to be specially repaired and filled with water every two months. Each maintenance cycle can save 20×1650=33,000 minutes of operation time. It is estimated that 3,300 hours of maintenance time can be saved each year. Calculated based on 8 hours of work per day, it is equivalent to the annual workload of two passenger car inspectors.

[0004] For example, the automatic water-adding system for batteries disclosed in publication number CN204333102U includes a distilled water tank and an automatic water-adding device arranged between the battery body and the distilled water tank. The automatic water-adding device includes a pipe connecting the battery and the distilled water tank, a valve arranged on the pipe, a guide frame arranged on the inner side of the water inlet of the battery, and a buoyancy piston arranged in the guide frame. The middle part of the buoyancy piston is provided with a plunger boss corresponding to the water inlet of the battery. The prior art can automatically add water and can automatically stop, and can add water in batches, which greatly reduces the labor intensity of manual labor.

[0005] Although the existing technology can achieve the effect of adding water in batches, its water adding action still needs to connect pipes before the batch effect can be completed. Moreover, since it is still a pipe, if the middle pipe is not flowing, the subsequent pipes cannot complete the water adding. Since the train batteries are different from those in other fields, the train batteries are large in number and are installed in an array on the train. The batteries are generally unable to move, and one of the batteries cannot be skipped when adding water. Therefore, its use is still relatively troublesome. Summary of the invention

[0006] The purpose of the present invention is to provide an integrated intelligent water-adding device for batch batteries to solve the problems raised in the above-mentioned background technology. In this solution, multiple water-adding pipes are concentrated on one pipe, and synchronous detection and water-adding actions can be completed in one action without taking over the pipe. At the same time, the movable water-adding pipe can skip the batteries that do not need water-adding and continue to complete efficient water-adding.

[0007] To achieve the above object, the present invention provides the following technical solution: an integrated batch battery intelligent water adding device, comprising a mobile battery box and a plurality of water adding pipes, the mobile battery box is equipped with a limit plate for placing the plurality of water adding pipes, one end of the water adding pipe is connected to a water source pipe, and the water source pipe is provided with a control box;

[0008] A telescopic rod is movably connected between the two water-adding pipes to adjust the distance between the two water-adding pipes, so that the storage battery that does not need water-adding can be skipped;

[0009] A plurality of water adding pipes and the telescopic rod are connected together to form a straight pipe, and no less than five water adding pipes are provided, so that water can be added to a plurality of storage batteries at the same time.

[0010] Preferably, the outer wall of the water filling pipe is connected to a connector, one end of the connector is connected to an entry-type liquid level detection rod, an electromagnetic valve is installed between the entry-type liquid level detection rod and the connector, and is electrically connected to the controller in the control box.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Embodiment 1

[0026] See also Figure 1-Figure 2 The integrated batch battery intelligent water adding device comprises a mobile battery box and a plurality of water adding pipes 1, a limiting plate 104 for placing the plurality of water adding pipes 1 is installed on the mobile battery box, one end of the water adding pipe 1 is connected to a water source pipe 4, and a control box 3 is arranged on the water source pipe 4;

[0027] Several water supply pipes 1 and telescopic rods 2 are connected together to form a straight pipe, and at least five water supply pipes 1 and telescopic rods 2 are provided, so that water can be added to multiple batteries at the same time;

[0028] The outer wall of the water supply pipe 1 is connected to a connector 101, one end of which is connected to an entry-type liquid level detection rod 103. An electromagnetic valve 102 is installed between the entry-type liquid level detection rod 103 and the connector 101, and is electrically connected to the controller in the control box 3.

[0029] The lower section of the entry-type liquid level detection rod 103 is sleeved with an outer sleeve 105 and a limit plate 104 , and the outer sleeve 105 is connected to a surface of the limit plate 104 facing away from the electromagnetic valve 102 .

[0030] One side of the connector 101 is connected to a filling hose 106 that passes through the limit plate 104. The portion of the filling hose 106 that passes through the limit plate 104 is located in the outer sheath 105. The outer sheath 105 is provided to protect the filling hose 106 and the entry-type liquid level detection rod 103 to avoid contamination and corrosion of the outer wall.

[0031] Specifically, the integrated water-adding structure of the present solution can complete multiple battery detection and water-adding actions at the same time by placing them once, without the need to insert them one by one, thus improving efficiency and saving labor;

[0032] When in use, the water source pipe 4 is connected to a water source and an external power source or a mobile battery box, the water supply pipe 1 is placed on the train battery, and the connecting hose 204 is connected to the water source pipe 4;

[0033] The inlet type liquid level detection rod 103 detects the liquid level of the battery and reports the data, and transmits it to the electrically connected controller. The controller activates the electromagnetic valve 102 according to different battery liquid level conditions, allowing water to be poured into the battery through the connecting hose 204 and the pouring hose 106. Of course, the battery liquid level can be set to a certain value first. If it is less than the certain value, water is added. If it is equal to or greater than the certain value, no water is added.

[0034] The outer package 105 is made of Teflon.

[0035] Embodiment 2

[0036] See also Figure 3 -and Figure 4 A telescopic rod 2 is movably connected between the two water-adding pipes 1 for adjusting the distance between the two water-adding pipes 1, so that the battery that does not need to be watered can be skipped;

[0037] A movable frame 201 is arranged inside the water-adding pipe 1 and is sleeved on one end of the telescopic rod 2. A movable slider 202 is fixedly connected to the movable frame 201. A movable slide groove 203 cooperating with the movable slider 202 is provided on the water-adding pipe 1. The position of the water-adding pipe 1 can be adjusted by the sliding telescopic rod 2. In this way, when a certain section of the battery does not need to be watered, it can be skipped and multiple water-adding actions can be continued at the same time without affecting the water-adding efficiency.

[0038] Located in the water filling pipe 1, a connecting hose 204 is connected between the two telescopic rods 2, and a water filling hose 205 is connected to the end of the connecting hose 204 facing one of the telescopic rods 2, and the water filling hose 205 is connected to the filling hose 106; the connecting hose 204 of this solution is arranged inside the water filling pipe 1, which is equivalent to having a storage effect, avoiding the risk of the connecting hose 204 being exposed to the outside and being torn or damaged;

[0039] Specifically, when the device is in use, it can not only complete the action of adding water at the same time, but also, if it is found during detection that the water level of one of the batteries is within the range, there is no need to add water;

[0040] The water-adding pipe 1 that moves in position can move the water-adding pipe 1 at the front end to the battery again, that is, change the water-adding pipe 1 to detect the same battery again. If it still does not need to be watered, it is determined that the battery does not need to be watered, so the battery is skipped and other batteries are tested and watered;

[0041] The telescopic rod 2 is different from the water flowing directly between the telescopic rod 2 and the water supply pipe 1. Instead, the water is connected through the connecting hose 204, which solves the problem of water leakage caused by poor sealing between the water supply pipe 1 and the telescopic rod 2.

[0042] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
