[0031] Detailed Implementation

[0032] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0033] The automatic water injection device and aerial work platform according to the present invention are described below with reference to the accompanying drawings.

[0034] like Figure 1 As shown, the automatic water filling device in this application is used to fill the battery box with water. The battery box is divided into multiple storage spaces for placing batteries. The top of the battery box has multiple water inlets, each corresponding to a storage space. The automatic water filling device includes a water tank assembly, a water supply pipe 2, a first liquid level detection device, and a control unit. The water tank assembly has a liquid storage chamber 131 inside, which stores liquid for replenishing the storage spaces. One end of the water supply pipe 2 is connected to the liquid storage chamber 131, and the other end forms multiple water supply branches 21, the same number as the water inlets, each corresponding to a storage space. Each storage space is equipped with a first liquid level detection device, which is used to obtain the current liquid level information of the storage space. The control unit is electrically connected to each first liquid level detection device, and the control unit can control the water supply pipe 2 to connect or disconnect according to the current liquid level information. Specifically, when the current liquid level information in any storage space is detected to be insufficient, the control unit can automatically control the water supply pipe 2 to connect, so that the liquid in the storage chamber 131 can be replenished from the water supply branch 21 to the corresponding storage space lacking liquid, thereby realizing automatic liquid replenishment. After the liquid is replenished, the water supply pipe 2 can be disconnected, thus completing the automatic liquid replenishment of the storage space.

[0035] Furthermore, the automatic liquid filling device of this application can be applied to devices such as lead-acid batteries. This embodiment uses a lead-acid battery as an example for explanation. Lead-acid batteries are usually immersed in liquid. Since the lead-acid battery itself dissipates a large amount of heat during operation, it will evaporate the liquid. Therefore, it is necessary to replenish the lead-acid battery with liquid regularly to prevent the lead-acid battery from overheating and causing a safety accident after the liquid evaporates. In this embodiment, the liquid inside the liquid storage chamber 131 is water, which serves as the evaporating liquid for the lead-acid battery. Other liquids can be added if necessary, and the specific adjustments can be made according to actual needs.

[0036] This application proposes an automatic water filling device. When a lack of liquid is detected in any storage space, the control unit can control the water supply pipe 2 to connect, so that the liquid in the storage chamber 131 flows through the water supply pipe 2 and automatically replenishes the storage space lacking liquid along the water supply branch 21. After the liquid in the storage space is replenished, the water supply pipe 2 is automatically disconnected, realizing automatic liquid replenishment of the battery and solving the technical problem of inconvenient liquid replenishment of the battery box in the prior art.

[0037] In this embodiment, a water pump is also installed on the water supply pipeline 2. The control unit is connected to both the water pump and the first liquid level detection device. The control unit is used to drive the water pump to start or stop according to the current liquid level information transmitted by the first liquid level detection device. Specifically, there are multiple water pumps, each corresponding to a water supply branch 21, to ensure that when any of the first liquid level detection devices detects a lack of water in the storage space, the water pump on the corresponding water supply branch 21 can be activated to achieve precise liquid replenishment.

[0038] Furthermore, the control unit has preset first and second liquid level parameters. The control unit compares the received current liquid level information with the preset parameters. When the first liquid level detector detects that the current liquid level in the storage space is lower than the first liquid level parameter, it determines that the storage space is short of water and reports the current liquid level information to the control unit. At this time, the water supply branch 21 of the corresponding short-liquid storage space can be connected to replenish the liquid in a timely manner. When the first liquid level detector detects that the current liquid level in the storage space is higher than the second liquid level parameter, it determines that the liquid in the storage space has been replenished, and the water supply branch 21 of the replenished storage space can be disconnected to prevent overfilling. When the first liquid level detector detects that the current liquid level in the storage space is between the first and second liquid level parameters, it determines that the liquid in the storage space is in a normal state and no replenishment is needed. The values ​​of the first and second liquid level parameters can be adjusted according to actual needs.

[0039] In this embodiment, the automatic water filling device also includes an alarm module and a second liquid level detection element disposed in the liquid storage chamber 131. The control unit is electrically connected to both the alarm module and the second liquid level detection element. The control unit controls the alarm module to issue an alarm based on the current liquid level information transmitted by the first and second liquid level detection elements. The control unit has a preset third liquid level parameter. When the second liquid level detection element detects that the current liquid level is lower than the third liquid level parameter, it determines that there is a shortage of liquid in the liquid storage chamber 131 and sends feedback to the control unit. The control unit then controls the alarm module to issue an alarm, reminding staff to replenish the liquid in the liquid storage chamber 131. The value of the third liquid level parameter can be adjusted as needed. Additionally, when the first liquid level detection element detects that the current liquid level in the storage space is higher than the second liquid level parameter, the control unit controls the alarm module to issue an alarm, reminding staff that water filling is complete. Conversely, when the first liquid level detection element detects that the current liquid level in the storage space is lower than the first liquid level parameter, the control unit controls the alarm module to issue an alarm, reminding staff that some parts of the storage space are low on liquid, thus providing timely early warning. The first liquid level detection element and the second liquid level detection element are both liquid level sensors in the prior art.

[0040] like Figure 1 and Figure 2 As shown, in this embodiment, the automatic water injection device also includes a mounting bracket 3. The mounting bracket 3 includes a vertical plate 31 and a horizontal plate 32 integrally connected. A platform for placing the water tank assembly is formed on the horizontal plate 32 to support the water tank assembly. The vertical plate 31 is used for detachable connection with an external workpiece. Taking the external workpiece connected to the mounting bracket 3 in this embodiment as an example, by detachably connecting the vertical plate 31 to the boom lift chassis, it is ensured that the water tank assembly can be stably installed on the boom lift chassis.

[0041] like Figure 1 , Figure 2 and Figure 4 As shown, in this embodiment, the automatic water filling device further includes reinforcing plates 33 disposed on both sides of the horizontal plate 32 along its width direction. The water tank assembly is located between the two reinforcing plates 33. One side of the reinforcing plate 33 along its length direction is connected to the vertical plate 31, and the other side is connected to the horizontal plate 32. The width direction of the horizontal plate 32 is... Figure 1 In the left and right directions, the reinforcing plate 33 has a triangular structure, which provides good support stability and can further improve the structural strength of the mounting bracket 3.

[0042] like Figure 1 and Figure 2As shown, in this embodiment, the automatic water filling device also includes a locking fastener 4. An elongated hole 311 is provided on the vertical plate 31, extending along the height direction of the water tank assembly. The locking fastener 4 passes through the elongated hole 311 to lock the vertical plate 31 to the external workpiece. Specifically, in this embodiment, two elongated holes 311 are provided on the vertical plate 31, spaced apart along the width direction of the vertical plate 31. By inserting the locking fastener 4 into different positions within the elongated holes 311 and locking the vertical plate 31 to the external workpiece, the position of the water tank assembly in the height direction can be adjusted to better match the position of the battery box. The width direction of the vertical plate 31 is... Figure 1 The left and right directions of the water tank assembly, and the height direction of the water tank assembly are as follows: Figure 1 The up and down directions in the middle.

[0043] like Figure 4 As shown, in this embodiment, the water tank assembly includes a housing 11 with a top opening. The bottom of the housing 11 is detachably connected to a horizontal plate 32. A cover plate 12 is detachably connected to the housing 11 and used to close the top opening. A water tank 13 is disposed inside the housing 11 and has a liquid storage chamber 131. A water supply pipe 2 sequentially and sealingly penetrates the bottom of the horizontal plate 32, the housing 11, and the water tank 13 and is inserted into the liquid storage chamber 131 to prevent leakage from the bottom of the water tank 13. The housing 11 serves to protect the water tank 13 from impacts and damage that could lead to leakage.

[0044] like Figure 3 As shown, in this embodiment, the water tank assembly includes a water tank lid 14, and the water tank 13 includes a water tank body 132 and a liquid inlet 133 communicating with the top of the water tank body 132. The liquid inlet 133 extends away from the liquid storage chamber 131 and has a liquid inlet for communicating with an external water supply pipe. The water tank lid 14 is used to cover the liquid inlet. When it is necessary to add liquid to the liquid storage chamber 131, the cover plate 12 can be removed from the housing 11 first, and then the water tank lid 14 can be unscrewed. At this time, the external water supply pipe can be connected to the liquid inlet to replenish the liquid storage chamber 131. After the replenishment is completed, the external water supply pipe is removed, the liquid inlet is covered by the water tank lid 14, and then the cover plate 12 is detachably connected to the housing 11, thus completing the replenishment of the liquid storage chamber 131. Specifically, in this embodiment, the outer peripheral wall of the liquid inlet 133 is provided with an external thread, and the inner wall of the bucket lid 14 has an internal thread that matches the external thread. The bucket lid 14 covers the liquid inlet 133, which can prevent liquid from spilling out from the liquid inlet.

[0045] In this embodiment, the bottom of the water tank 13 has an outlet through which the water supply pipe 2 passes. The outer peripheral wall of the water supply pipe 2 near the end of the water tank assembly has an external thread that matches the internal thread on the inner wall of the outlet, so as to achieve a tight connection between the water supply pipe 2 and the water tank body 132, which facilitates assembly.

[0046] In this embodiment, an aerial work platform is also proposed, including the automatic water injection device described above. Since the aerial work platform adopts all embodiments of the automatic water injection device in this application, it also possesses all the beneficial effects of the automatic water injection device, which will not be elaborated upon here. Specifically, the aerial work platform can be a machine such as a boom lift; in this application, the automatic water injection device is described as being installed on the chassis of a boom lift.
