DETAILED DESCRIPTION

[0035] In the following description, a large number of specific details are given to provide a more thorough understanding of the present application. However, it is apparent to those skilled in the art that the present application can be implemented without one or more of these details. In other examples, some technical features known in the art are not described in order not to obscure the present application with unnecessary detail.

[0036] In order to thoroughly understand the present application, detailed structures will be presented in the following description. It is obvious that the implementation of the present application is not limited to the special details familiar to those skilled in the art.

[0037] As Figures 1 to 6As shown, the utility model provides a kind of liquid level early warning detection system, the liquid level early warning detection system of the utility model is arranged in the floor 200 of energy storage integrated cabin, floor 200 has leakage hole 201 on it.Energy storage integrated cabin is often installed with more electrical components, after electrical component works for a period of time, it can lead to the temperature rise in energy storage integrated cabin, to avoid the security risk due to temperature being too high, then the electrical component in energy storage integrated cabin needs to be cooled, i.e., electrical component can be cooled by the mode that water or ethylene glycol etc. are installed in pipeline, after pipeline works for a period of time, it is easy to be loosened due to vibration or aging at connecting portion, to lead to the situation that the connecting portion of pipeline is easy to leak, to avoid liquid in pipeline drop on the floor 200 of energy storage integrated cabin, then leakage hole 201 set on the floor 200 can flow into the liquid storage tank 110 of the utility model, liquid is collected by liquid storage tank 110.

[0038] As Figure 1 And Figure 2 As shown, the liquid level early warning detection system according to the utility model includes liquid storage tank 110, electromagnetic valve 119 and controller 113.

[0039] In an embodiment of the utility model, liquid storage tank 110 is used to be set below floor 200, and the upper end of liquid storage tank 110 has opening (not shown in the drawing), opening is towards leakage hole 201, and the bottom wall of liquid storage tank 110 has drainage hole 111.

[0040] Electromagnetic valve 119 is arranged in drainage hole 111.

[0041] First water liquid detector 112 is arranged in the area close to leakage hole 201, and first water liquid detector 112 is configured to emit leakage electric signal when contacting the liquid that flows from liquid storage tank 110 through leakage hole 201.

[0042] The controller 113 is electrically connected to the electromagnetic valve 119 and the first water liquid detector 112 respectively, and the controller 113 is configured to control the electromagnetic valve 119 to open to discharge the accumulated liquid in the liquid storage tank 110 when receiving the liquid leakage electric signal. The liquid level early warning detection system in the utility model can be used for collecting the liquid in the energy storage integrated cabin through the additional liquid storage tank 110, so as to avoid that the liquid directly drips to the outside of the energy storage integrated cabin through the liquid leakage hole 201, avoid that the liquid causes certain pollution to the environment, and achieve the purpose of environmental protection. Meanwhile, the liquid can also be effectively prevented from dripping on the floor 200 in the energy storage integrated cabin, so as to avoid that the electric elements are short-circuited. In addition, in order to prevent that the liquid in the liquid storage tank 110 is accumulated too much and flows back to the floor 200 of the energy storage integrated cabin through the liquid leakage hole 201, and causes a safety hazard to other electric elements, the utility model additionally provides the electromagnetic valve 119, the first water liquid detector 112 and the controller 113, the controller 113 is electrically connected to the electromagnetic valve 119 and the first water liquid detector 112 respectively, when the first water liquid detector 112 detects the liquid flowing out from the liquid storage tank 110 through the liquid leakage hole 201, the first water liquid detector 112 will send a liquid leakage electric signal, and the controller 113 will control the electromagnetic valve 119 to open after receiving the liquid leakage electric signal, so that the accumulated liquid in the liquid storage tank 110 is discharged, so that the problem that the liquid storage tank 110 is leaked due to too much accumulated liquid is effectively avoided, and further, the accumulated liquid in the liquid storage tank 110 is prevented from flowing back, so that the circuit safety hazard in the energy storage integrated cabin is avoided.

[0043] It should be noted that when the electromagnetic valve 119 is opened, the liquid discharge hole 111 will be communicated with a specific collection device, so as to avoid that the liquid is directly discharged, and ensure that the purpose of environmental protection is achieved.

[0044] In a specific embodiment of the utility model, the first water liquid detector 112 can be a water immersion rope or a water immersion sensor. It should be noted that the working principle of the water immersion rope or the water immersion sensor is known to those skilled in the art, and for the sake of saving space, it will not be repeated here.

[0045] In addition, it should be noted that the structure and working principle of the controller 113 are known to those skilled in the art, and for the sake of saving space, it will not be repeated here.

[0046] As shown in the figure, Figure 5 In some preferred embodiments of the utility model, the floor 200 of the energy storage integrated cabin has an open mouth (not shown in the figure), the open mouth is in butt joint communication with the opening of the liquid storage tank 110, and the cover plate 202 is sealed and covered at the open mouth.

[0047] The top surface of the cover plate 202 has an inclined surface (not shown in the figure), and the leakage hole 201 is provided on the inclined surface. The first water detector 112 is provided on the cover plate 202, and the first water detector 112 is located at the bottom of the inclined surface. By providing an inclined surface on the top surface of the cover plate 202 and placing the first water detector 112 at the bottom of the inclined surface, when the first water detector 112 detects water, it will immediately send a leakage electrical signal to the controller 113. The controller 113 will then control the solenoid valve 119 provided in the drain hole 111 to open, so that the accumulated liquid in the storage tank 110 can be discharged in a timely manner.

[0048] like Figure 5 As shown, in some preferred embodiments of this utility model, the cover plate 202 is a transparent cover plate. This allows operators to visually observe changes in the liquid level within the storage tank 110. Simultaneously, it facilitates timely monitoring of the liquid level changes in the storage tank 110 using the second liquid detector 114 or color-changing adhesive strip 115, preventing excessive liquid in the storage tank 110 from flowing back up to the floor 200 of the energy storage integrated compartment via the leakage hole 201. Furthermore, this effectively avoids potential safety hazards within the energy storage integrated compartment.

[0049] It should be noted that, in order to ensure a sealed connection between the cover plate 202 and the opening, sealing strips or silicone strips may be provided around the cover plate 202 or the opening to enhance the sealed connection between the cover plate 202 and the opening.

[0050] In some preferred embodiments of this utility model, the liquid level early warning detection system further includes:

[0051] Multiple second water level detectors 114 are installed inside the storage tank 110 and spaced apart along the height direction DH of the storage tank 110. Each second water level detector 114 is electrically connected to the controller 113. By installing multiple second water level detectors 114 at intervals along the height direction DH of the storage tank 110, the liquid level information in the storage tank 110 can be effectively monitored. When liquid at different levels comes into contact with the second water level detector 114 installed at different levels, the corresponding second water level detector 114 will send an electrical signal to the controller 113 to remind staff or maintenance personnel to confirm on-site and perform drainage, so as to more accurately judge the liquid level change in the storage tank 110. At the same time, it can also effectively prevent the liquid in the storage tank 110 from overflowing onto the floor 200 of the energy storage integrated compartment due to excessive accumulation, effectively avoiding potential safety hazards to electrical components.

[0052] It should be noted that the structure and working principle of the second water liquid detector 114 are the same as those of the first water liquid detector 112 described above, and for the sake of brevity, they will not be repeated here.

[0053] It should also be noted that, in order to reduce signal interference and have the effect of corrosion prevention, a shielding layer can be provided on the outer surface of the first water liquid detector 112 and the second water liquid detector 114.

[0054] As shown in Figure 1 and Figure 3 In some preferred embodiments of the present application, the liquid level early warning detection system further comprises a plurality of color-changing adhesive test papers 115, which are arranged in the liquid storage tank 110 and are spaced apart along the height direction DH of the liquid storage tank 110. By arranging the color-changing adhesive test papers 115 at multiple points in the liquid storage tank 110, the color-changing adhesive test papers 115 will change color when they come into contact with water, and will automatically return to their original color when the water dries. By observing the color of the color-changing adhesive test papers 115, it is possible to more directly observe whether water has entered the liquid storage tank 110, which facilitates daily inspection by on-site maintenance personnel.

[0055] In some preferred embodiments of the present application, the liquid level early warning detection system further comprises a monitoring probe 116, which is arranged above the first water liquid detector 112 and is electrically connected to the controller 113. By arranging the monitoring probe 116 above the first water liquid detector 112, it is possible to more accurately and comprehensively detect whether there is liquid returning from the liquid storage tank 110 on the floor 200 of the energy storage integrated cabin, so that in the event of a liquid leak in an area that cannot be detected by the first water liquid detector 112, the arrangement of the monitoring probe 116 effectively improves the reliability of liquid monitoring.

[0056] As shown in Figures 1 to 3 In some preferred embodiments of the present application, the liquid level early warning detection system further comprises a drainage pipeline 117, which is sealingly connected to the liquid discharge hole 111. The arrangement of the drainage pipeline 117 facilitates communication with a specific collection device, so that the accumulated liquid in the liquid storage tank 110 can be smoothly discharged into the specific collection device, thereby avoiding direct discharge and causing environmental pollution.

[0057] In some preferred embodiments of the present application, the liquid level early warning detection system further comprises a corrosion-resistant coating (not shown in the figure), which is sprayed on the inner surface of the liquid storage tank 110. By spraying the corrosion-resistant coating on the inner surface of the liquid storage tank 110, it is possible to effectively prevent the accumulated liquid in the liquid storage tank 110 from corroding or rusting.

[0058] Preferably, the corrosion-resistant coating can be a galvanized layer or a stainless steel layer, both of which have the characteristic of preventing rusting.

[0059] As Figure 2 shown, in some preferred embodiments of the present application, the liquid level early warning detection system further comprises a plurality of partitions 118, which are vertically arranged on the bottom wall of the liquid storage tank 110, and the two sides of each partition 118 are sealingly connected with the side wall of the corresponding liquid storage tank 110, and the top end surface of each partition 118 is lower than the top end surface of the side wall of the liquid storage tank 110. By arranging a plurality of partitions 118 inside the liquid storage tank 110, the interior of the liquid storage tank 110 is divided into different storage areas. When the liquid storage in a certain storage area is full, in order to prevent the liquid in this area from overflowing, since the top end surface of the partition 118 is lower than the top end surface of the side wall of the liquid storage tank 110, the liquid can flow into the adjacent storage area through the partition 118.

[0060] According to the second aspect of the present application, a storage energy integrated cabin is also provided, which comprises the liquid level early warning detection system described in the above embodiments.

[0061] As Figure 4 shown, in some preferred embodiments of the present application, the floor 200 has a groove 203, the bottom wall of the groove 203 has a plurality of through holes (not shown in the figure), the through holes are directed towards the liquid storage tank 110, and the first water liquid detector 112 is arranged in the groove 203. Specifically, the groove 203 is arranged in the floor 200 to provide a fixed mounting space for the first water liquid detector 112. In addition, a plurality of through holes are arranged on the bottom wall of the groove 203, so that when the liquid storage tank 110 is full of liquid, the liquid will return to the groove 203 through the through holes. In this way, when the first water liquid detector 112 encounters liquid, it will send a liquid leakage electrical signal to the controller 113, and the controller 113 will control the electromagnetic valve 119 to open, so as to timely drain the liquid in the liquid storage tank 110, avoiding the short circuit of the electrical components in the storage energy integrated cabin caused by the overflow of the liquid. It should be noted that when the liquid in the liquid storage tank 110 fills the entire tank, before the electromagnetic valve 119 is opened, a specific device connected by the drain pipe 117 will be used to collect the liquid in the liquid storage tank 110, avoiding environmental pollution caused by direct discharge.

[0062] In summary, the liquid level early warning detection system in the utility model can be used for collecting the liquid in the energy storage integrated cabin through the additional liquid storage tank 110, avoiding the liquid directly dropping to the outside of the energy storage integrated cabin through the liquid leakage hole 201, avoiding causing certain pollution to the environment, achieving the purpose of environmental protection. At the same time, liquid dropping to the floor 200 in the energy storage integrated cabin can also be effectively prevented, avoiding the short circuit of the electrical components. In addition, in order to prevent the liquid in the liquid storage tank 110 from being accumulated too much and flowing back to the floor 200 of the energy storage integrated cabin through the liquid leakage hole 201, causing safety hazards to other electrical components, the utility model adds the electromagnetic valve 119, the first water liquid detector 112 and the controller 113, so that the controller 113 is electrically connected with the electromagnetic valve 119 and the first water liquid detector 112 respectively, when the first water liquid detector 112 detects the liquid flowing out of the liquid storage tank 110 through the liquid leakage hole 201, the first water liquid detector 112 will send a liquid leakage electric signal, and the controller 113 will control the electromagnetic valve 119 to open after receiving the liquid leakage electric signal, so as to discharge the accumulated liquid in the liquid storage tank 110, thereby effectively avoiding the problem of liquid leakage of the liquid storage tank 110 due to excessive accumulation of liquid, and further avoiding the problem of liquid accumulation in the liquid storage tank 110 returning to the energy storage integrated cabin, causing safety hazards of the circuit in the energy storage integrated cabin.
