The position of the liquid supply pipe corresponding to each battery module is connected to a liquid supply branch pipe, and the end of the liquid supply branch pipe away from the liquid supply pipe is connected to the liquid cooling plate of the corresponding battery module. The position of the liquid return pipe corresponding to each battery module is connected to a liquid return branch pipe, and the end of the liquid return branch pipe away from the liquid return pipe is connected to the liquid cooling plate of the corresponding battery module. A liquid cooling unit is arranged on the top of the cabinet, and the top of the liquid supply pipe and the top of the liquid return pipe are both connected to the liquid cooling unit. The liquid-cooled energy storage cabinet in the above scheme is not perfect in terms of safety and intelligence.

[0003] We found that the above technology has the following problems: We know that the liquid supply main and the liquid return main may leak after long-term operation. Condensation water is also easily formed on the liquid cooler and drips from top to bottom. Water accumulates in the cabinet. If it is not discovered in time, it may easily cause accidents and pose a safety hazard.

[0004] Therefore, the technical problem that needs to be solved is how to improve the safety performance of the liquid-cooled energy storage cabinet. Utility Model Content

[0006] To achieve the above-mentioned purpose and other related purposes, the present application adopts the following technical scheme: a liquid-cooled energy storage cabinet, comprising a cabinet body, a refrigeration unit, an energy storage inverter, a high-voltage box and multiple battery pack modules, wherein the energy storage inverter, the high-voltage box and multiple battery pack modules are fixed in the cabinet body from bottom to top in sequence, and cabinet doors are arranged at the front and rear of the cabinet body. The refrigeration unit is located at the bottom of the cabinet body on one side of the energy storage inverter. A water immersion sensor is arranged at the bottom of the cabinet body, and the water immersion sensor is connected to a signal judgment module, which is connected to a controller, and the controller is connected to an alarm, wherein the water immersion sensor outputs a sensing signal when it detects that the water level reaches a detection warning value, and the signal judgment module receives the sensing signal and judges the duration of the sensing signal. If the duration of the sensing signal is greater than a preset duration threshold, a true signal is output; if the sensing signal is less than or equal to the preset duration threshold, a false signal is output, and when the controller receives a true signal, the alarm is controlled to sound an alarm, and when the controller receives a false signal, the alarm is controlled to standby.

[0007] Optionally, a scale bar is provided on the cabinet, and the water immersion sensor is installed next to the scale bar through a sliding structure and is used to adjust the installation height. The sliding structure includes a slide rail, a slider and a fastening bolt. The slider is slidably installed on the slide rail, the slide rail is fixed on one side of the scale bar, the slider is fixedly connected to the water immersion sensor, and the slider is provided with a fastening bolt, which fastens the slider to the slide rail.

If there is a lot of water accumulation, the water immersion sensor will detect it and output a sensing signal, thereby enabling an alarm to be realized through the sensing signal. In order to avoid false triggering, the cabinet shakes and causes the water level to change, which requires further identification through the signal judgment module. This avoids the possibility of false triggering, thereby improving the reliability of the alarm. In this way, maintenance personnel can discover problems in time, drain water or perform maintenance to avoid causing greater accidents. This improves the level of intelligence and safety.

[0021] The following describes the embodiments of the present application through specific examples, and those skilled in the art can easily understand other advantages and effects of the present application from the contents disclosed in this specification. The present application can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present application. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0022] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present application. The illustrations only show the components related to the present application rather than being drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the type, quantity and proportion of each component can be changed at will, and the component layout type may also be more complicated.

[0023] The specific implementation methods of the present application will be further described below in conjunction with the accompanying drawings. Example

[0024] The present application embodiment discloses a liquid-cooled energy storage cabinet, referring to Figure 1 As shown, it includes a cabinet 1, a refrigeration unit, an energy storage converter 2, a high-voltage box 3 and a plurality of battery pack modules 4. The above-mentioned spatial arrangement, in Figure 1As can be seen, the energy storage inverter 2, the high-voltage box 3, and multiple battery pack modules 4 are fixed in the cabinet 1 from bottom to top in sequence, cabinet doors 25 are set at the front and back of the cabinet 1, and the refrigeration unit is located at the bottom of the cabinet 1 on one side of the energy storage inverter 2.

[0025] exist Figure 3 As can be seen in the figure, a water sensor 24 is arranged at the bottom of the cabinet 1.

[0026] Specific, combined Figure 5 and Figure 6 The water sensor 24 is connected to the signal judgment module 26, the signal judgment module 26 is connected to the controller 27, and the controller 27 is connected to the alarm 28. The water sensor 24 outputs a sensing signal when it detects that the water level reaches the warning value of the detection. The signal judgment module 26 receives the sensing signal and judges the duration of the sensing signal. If the duration of the sensing signal is greater than the preset duration threshold (determined by the timing signal), a true signal is output; if the sensing signal is less than or equal to the preset duration threshold, a false signal is output. When the controller 27 receives the true signal, it controls the alarm 28 to sound an alarm. When the controller 27 receives the false signal, it controls the alarm 28 to standby.

[0027] The timing signal is controlled according to the existing timer, and the timing time can generally be set at 30 seconds. When the water level sensor 24 continuously senses that the water level is higher than the warning water level, the comparator LM1 outputs a true signal (high level), otherwise it is a false signal (low level). The controller 27 can be a processor module such as a PLC or a single-chip microcomputer. This simple signal processing can be achieved through the controller 27, and the alarm 28 can be controlled to alarm. The alarm 28 can be a buzzer 16, a speaker, etc.

[0028] It can be seen that the refrigeration unit is arranged at the bottom. In this way, if condensation water occurs in the refrigeration unit or there is water leakage at its interface, it can directly accumulate at the bottom of the cabinet 1. If there is a lot of water accumulation, the water immersion sensor 24 will detect and output a sensing signal, thereby realizing an alarm through the sensing signal. In order to avoid false triggering, the cabinet 1 shakes to cause the water level to change, and further identification is required through the signal judgment module 26. This avoids the possibility of false triggering, thereby improving the reliability of the alarm. In this way, maintenance personnel can discover problems in time, drain water or perform maintenance to avoid causing greater accidents. It can be seen that the level of intelligence and safety are improved.

[0029] Based on the above implementation, the following optimization can also be performed:

[0030] For example, a more specific solution can be selected, combined with Figure 4As shown, a scale bar 30 is provided on the cabinet 1, and the scale bar 30 is a sticker or ruler with scales. By adjusting the installation height position of the water immersion sensor 24, the installation height can be compared with the scale bar 30 to know the warning water level. The water immersion sensor 24 is installed on the scale bar 30 or installed next to the scale bar 30 through a sliding structure 29 and is used to adjust the installation height. The sliding structure 29 includes a slide rail 31, a slider 32 and a fastening bolt 33. The slider 32 is slidably installed on the slide rail 31. The slide rail 31 is fixed on one side of the scale bar 30. The slider 32 is fixedly connected to the water immersion sensor 24. The slider 32 is penetrated with a fastening bolt 33, and the fastening bolt 33 fastens the slider 32 to the slide rail 31. The fastening bolt 33 is on the side of the slider 32, so that the water immersion sensor 24 can be installed on the front of the slider 32.

[0031] exist Figure 3 In the embodiment, a drainage channel 34 is provided at the bottom of the cabinet 1, and a filter mesh 35 is fixed at the entrance of the drainage channel 34. Generally, the accumulated water can be discharged from here. In addition, in order to avoid clogging of the drainage channel 34, a filter mesh 35 is provided. If the filter mesh 35 is still blocked and the accumulated water cannot be discharged, it can be detected by the water immersion sensor 24. When an alarm is issued, the user can perform maintenance.

[0032] In addition to the above scheme, you can also refer to Figure 1 The installation positions of the touch panel 36 and the travel switch 12 are shown. The touch panel 36 is arranged on the top of the cabinet door 25 of the cabinet body 1, and the travel switch 12 is arranged inside the cabinet body 1. The travel switch 12 is used to sense the touch panel 36 to trigger a door closing signal when the cabinet door 25 is closed, and to trigger a door opening signal when the cabinet door 25 is opened. The travel switch 12 transmits the door opening signal or the door closing signal to the controller 27. Figure 5 and Figure 6 , this circuit can transmit the switch status of the cabinet door 25.

[0033] Optionally, the controller 27 is connected to a display (display screen 13), which displays a water level signal, a door opening signal or a door closing signal.

[0034] Finally, the travel switch 12 also passes through the relay module 37. The relay module 37 includes a coil control unit 38 and a switch contact unit 39. The switch contact unit 39 controls the power supply of the water immersion sensor 24. When the cabinet door 25 is in an open state, the water immersion sensor 24 is powered off and stops working; when the cabinet door 25 is in a closed state, the water immersion sensor 24 is powered on and works.

[0035] When the cabinet door 25 is in the open state, it means that someone is inspecting it. At this time, the travel switch 12 outputs a high level, so that the transistor is turned on, and then the coil part K1 of the relay is energized. The relay module 37 used at this time is a normally closed relay. After being energized, the switch contact part 39 (normally closed switch contact) is disconnected, thereby cutting off the power supply of the water immersion sensor 24, and the water immersion sensor 24 stops working. If no one is inspecting it, the cabinet door 25 is closed. At this time, the travel switch 12 outputs a low level, and the relay is not energized, so the normally closed switch contact is reset to the closed state, and the water immersion sensor 24 works normally.

[0036] Finally, in the above scheme, reference Figure 1 , Figure 2 As shown, other existing components installed in the cabinet 1 are as follows: fire gas pipeline 5, liquid cooling pipeline 6, fire cabinet 7, puncture valve 8, cluster detector 9, lighting lamp 10, uninterruptible power supply 11, display screen 13, distribution box 14, liquid cooling unit 15, buzzer 16, red indicator light 17, yellow indicator light 18, emergency stop button 19, explosion-proof ventilation valve 20, cooling fan 21, fire water pipe 22. By installing the above accessories, the safety performance can be further improved.

[0037] The above embodiments are only illustrative of the principles and effects of the present application, and are not intended to limit the present application. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application shall be included in the protection scope of the present application.
