Description

Technical Field

[0001] This utility model relates to the field of electrochemical energy storage technology, specifically to a cooling fluid treatment device for an energy storage converter. Background Technology

[0002] Electrochemical energy storage systems use electrochemical cells as energy storage carriers and store and release cyclic electrical energy through energy storage converters. The heat dissipation methods of these energy storage converters include water cooling, forced air cooling, and air-water cooling. Water-cooled energy storage converters use ethylene glycol aqueous solution as the coolant, which has the characteristics of high heat carrying capacity, low flow resistance, and high heat exchange efficiency.

[0003] Currently, adding coolant to energy storage converters is generally done manually. Common energy storage converter cabinets are about 2.5 meters high, and the liquid cooling system is usually located at the highest point of the converter. Therefore, workers need to carry coolant tanks using ladders or scaffolding to reach the coolant storage device, drain the waste coolant from the storage device, and then pour in new coolant. This process requires workers to climb high, is difficult, and carries the risk of foreign objects such as metal shavings, oil, and water entering the circuit board surface, causing equipment malfunctions. Furthermore, working at heights is inherently dangerous, and the voltage between the positive and negative terminals of the energy storage battery pack is very high; accidental contact during operation could also cause safety issues. Utility Model Content

[0049] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0050] A typical water-cooled energy storage converter cabinet consists of, from top to bottom, a liquid cooling system, a PCS (Power Conversion System), an EMS (Energy Management System), a high-voltage box, and battery packs. Commercially available energy storage converter cabinets are typically about 2.5 meters high. The liquid cooling system is located at the highest point of the cabinet, so the working height for adding coolant to the coolant storage device is also approximately 2.5 meters. Currently, when adding coolant, operators rely on ladders or scaffolding to carry heavy coolant tanks to the storage device. After opening the top cover, the waste coolant (the old coolant remaining in the storage device) must first be collected. This is because during high-frequency charging and discharging at the power plant, and prolonged operation, the coolant gradually decomposes, becoming cloudy or forming sediment, reducing its heat transfer efficiency and affecting the heat dissipation of the liquid cooling system. Only after the waste coolant is collected can new coolant be added to the storage device.

[0051] This operation requires operators to work at heights, which poses a risk of instability, falls, slips, and injuries. Furthermore, working at heights is difficult and time-consuming. Secondly, there is a risk of foreign objects such as metal shavings, oil, and water entering the circuit board surface, causing equipment malfunctions. Additionally, the voltage between the positive and negative terminals of the energy storage battery pack in the single cabinet of the energy storage converter is extremely high; accidental contact during refueling could result in electric shock and personal injury, posing a significant safety hazard.

[0052] To address the aforementioned issues, this embodiment provides a coolant treatment device for an energy storage converter, which can assist operators in performing process removal work, bringing convenience to operators and ensuring personal safety.

[0053] The following is combined Figures 1 to 9 This document describes embodiments of the present invention. According to one embodiment of the present invention, a coolant treatment device for an energy storage converter is provided, comprising: a moving component 1, a lifting component 2, a coolant filling component 3, and a waste liquid recovery component 4. The moving component 1 includes: a trolley 11 and moving wheel mechanisms 12, with two sets of moving wheel mechanisms 12 symmetrically arranged on both sides of the trolley 11. The lifting component 2 includes: a support platform 21 and a lifting mechanism 22, the lifting mechanism 22 being mounted on the trolley 11, with its drive end connected to the support platform 21. The coolant filling component 3 is mounted on the support platform 21 and includes: a first storage tank 31, a filling pipe 32, and a filling power mechanism 33. The first storage tank 31 stores coolant, the inlet end of the filling power mechanism 33 is connected to the first storage tank 31, and its outlet end is connected to the filling pipe 32, the filling pipe 32 being adapted to connect to the coolant storage device of the energy storage converter. Waste liquid recovery assembly 4 is installed on the first liquid storage tank 31, and includes: a second liquid storage tank 41, a liquid extraction pipe 42 and a liquid extraction power mechanism 43. The liquid extraction power mechanism 43 is connected to the liquid extraction pipe 42. The liquid outlet end of the liquid extraction pipe 42 is connected to the second liquid storage tank 41, and its liquid inlet end is adapted to be connected to a coolant storage device.

[0054] like Figure 1 , Figure 2 As shown, the trolley 11 is the main load-bearing component. Moving wheel mechanisms 12 are provided on both sides of the trolley 11 to allow it to move. In this embodiment, the trolley 11 is a handcart, comprising a flatbed body and handles mounted on the body, which can be moved manually. Of course, in other embodiments, the trolley 11 can also be an electric trolley 11, i.e., moved by electricity. The lifting assembly 2 is mainly used to change the working height of the coolant treatment device. Its support platform 21 is equipped with a coolant filling assembly 3 and a waste liquid recovery assembly 4. The lifting mechanism 22 is mounted on the trolley 11 and can drive the support platform 21, coolant filling assembly 3, and waste liquid recovery assembly 4 to rise and fall as a whole.

[0055] The coolant filling assembly 3 includes a first reservoir 31, a filling pipe 32, and a filling power mechanism 33. The first reservoir 31 stores coolant, which is an ethylene glycol aqueous solution. Coolant can be added through the filling hole 311 on the first reservoir. The first reservoir 31 can be a cylindrical tank, on which a level gauge 312 can be installed to observe the coolant level. Of course, in other embodiments, the first reservoir 31 can also be of other shapes, and this embodiment does not impose specific limitations. The filling power mechanism 33 is generally connected to the first reservoir 31 at the bottom of the first reservoir 31. The filling power mechanism 33 provides power to transport the coolant in the first reservoir 31 to the filling pipe 32. When the filling pipe 32 is connected to the coolant storage device, coolant can be smoothly added to the coolant storage device.

[0056] The waste liquid recovery assembly 4 is mounted on the first storage tank 31 to save space. Furthermore, the waste liquid recovery assembly 4 includes a second storage tank 41, a suction pipe 42, and a suction power mechanism 43. The second storage tank 41 can be directly mounted on the top surface of the first storage tank 31, and its shape is similar to that of the first storage tank 31. However, since the amount of waste liquid to be extracted is less than the amount of new coolant to be added, the volume of the second storage tank 41 is smaller than that of the first storage tank 31. The suction power mechanism 43 is connected to the suction pipe 42 to provide power for extracting the waste liquid. The outlet end of the suction pipe 42 is connected to the second storage tank 41. When the inlet end of the suction pipe 42 is connected to a coolant storage device, the waste liquid can be extracted into the second storage tank 41 via the suction pipe 42.

[0057] This energy storage converter coolant treatment device has three functions: lifting, adding coolant, and extracting waste liquid. It can assist operators in completing the entire process, reduce the workload of operators, reduce the difficulty and risk of operation, and bring convenience to operators.

[0058] In one embodiment, the moving wheel mechanism 12 includes: a connecting shaft 121, a connecting plate 122, and wheels 123. One end of the connecting shaft 121 is connected to the trolley 11, the connecting plate 122 is rotatably disposed at the other end of the connecting shaft 121, and three wheels 123 are rotatably disposed on the outer periphery of the connecting plate 122, and the included angle of any two adjacent wheels 123 is equal.

[0059] like Figures 1 to 5As shown, the moving wheel mechanism 12 is a three-wheeled planetary gear system. Specifically, three wheels 123 are arranged in an equilateral triangle at the three ends of the connecting plate 122 and are rotatably connected to the connecting plate 122. The center of the connecting plate 122 is rotatably connected to the connecting shaft 121. When traveling on flat ground, two of the wheels 123 are in contact with the ground, and the rotation of the wheels 123 drives the trolley 11 to move. When there are steps or stairs, the connecting plate 122 rotates around the connecting shaft 121, causing the trolley 11 to climb. This moving wheel mechanism 12 allows the coolant handling device to adapt to more application environments and has a wider range of applications.

[0060] In another embodiment, the moving wheel mechanism 12 can also be a regular wheel 123, which is directly mounted on the connecting shaft 121 and can drive the trolley 11 to walk on flat ground.

[0061] In one embodiment, the lifting mechanism 22 includes a hydraulic cylinder 221, the fixed end of which is disposed on the trolley 11, and the driving end of which is connected to the support platform 21.

[0062] Hydraulic cylinder 221 is a conventional piston cylinder 432. One end of the cylinder body (i.e., the fixed end of hydraulic cylinder 221) is fixedly connected to trolley 11, and one end of piston rod 432 (i.e., the driving end of hydraulic cylinder 221) is connected to support platform 21. Of course, a corresponding hydraulic system is also required on trolley 11, such as hydraulic oil tank, hydraulic pump, hydraulic pipeline and valve group, etc. The hydraulic pump pumps the oil in the hydraulic oil tank into hydraulic cylinder 221 to drive hydraulic cylinder 221 to rise and fall, thereby driving support platform 21 and the coolant filling assembly 3 and waste liquid recovery assembly 4 set on it to rise and fall as a whole to a suitable working height.

[0063] In one embodiment, the lifting assembly 2 further includes a scissor bracket 222, one end of which is connected to the trolley 11 and the other end is connected to the support platform 21, and the drive end of the hydraulic cylinder 221 is connected to the scissor bracket 222.

[0064] Specifically, such as Figure 1 , Figure 2 As shown, each scissor lift bracket 222 includes two support frames, left and right. The bottom end of each support frame is connected to the trolley 11, and the top end is connected to the support platform 21. The two support frames are connected by multiple crossbars. The drive end of the hydraulic cylinder 221 is connected to the highest crossbar. The lifting and lowering of the hydraulic cylinder 221 can drive the scissor lift bracket 222 to lift and lower, synchronously driving the support platform 21 to lift and lower. The scissor lift bracket 222 improves the stability of the lifting assembly 2 during the lifting process.

[0065] In one embodiment, the energy storage converter coolant treatment device further includes a rotating assembly 5, which includes an upper turntable 51, a lower turntable 52 and a rotating shaft. A first liquid storage tank 31 is disposed on the upper turntable 51, and the lower turntable 52 is disposed on the support platform 21. The upper turntable 51 and the lower turntable 52 are disposed opposite to each other and connected by the rotating shaft.

[0066] The rotating shaft can be positioned at the center of the upper turntable 51 and the lower turntable 52. Rotating the upper turntable 51 changes the working position of the suction tube 42. To improve the support stability of the upper turntable 51, multiple support rods can be spaced along the edges between the upper and lower turntables 51 and 52. To avoid affecting the rotation of the upper turntable 51, a groove can be provided on the surface of the upper turntable 51, allowing the upper ends of the support rods to slide within the groove when the upper turntable 51 is rotated.

[0067] Of course, in other embodiments, the rotating component 5 may not be provided, and the first liquid storage tank 31 may be directly placed on the support platform 21.

[0068] In one embodiment, the liquid filling power mechanism 33 includes a power unit 331 and a tap 332. The liquid inlet end of the power unit 331 is connected to the first liquid storage tank 31. The tap 332 has a liquid inlet head and multiple liquid outlet heads communicating with it. The liquid inlet head is connected to the liquid outlet end of the power unit 331, and each liquid outlet head is connected to a liquid filling pipe 32.

[0069] Specifically, such as Figure 7 As shown, the power unit 331 is a liquid pump, which is connected to the first liquid storage tank 31 via a pipeline to pump the internal coolant to the filling pipe 32. The tap 332 is connected to the outlet of the liquid pump and can be branched into multiple paths through multiple outlets. Each outlet is connected to a filling pipe 32, allowing coolant to be added to multiple coolant storage devices simultaneously. The filling pipe 32 is preferably a flexible hose for easy operation of adding coolant.

[0070] In one embodiment, each outlet head is equipped with a first regulating valve 333. For example... Figure 7 As shown, the first regulating valve 333 is used to regulate the flow rate of the corresponding outlet head in order to meet the liquid inlet requirements of different coolant storage devices.

[0071] In one embodiment, the extraction pipe 42 is a retractable hose. Since extracting waste liquid requires reaching into the bottom of the coolant storage device, while adding coolant only requires adding it through the opening of the coolant storage device, the required length of the extraction pipe 42 is relatively long. Choosing a retractable hose meets the usage requirements and allows it to be retracted when not in use, resulting in a shorter overall length for easy handling.

[0072] In one embodiment, the pumping power mechanism 43 includes: an air guide pipe 431, a piston 432, and a driving member 433. One end of the air guide pipe 431 is connected to the second liquid storage tank 41, and the other end is connected to the piston 432. The piston 432 includes: a housing, an exhaust valve 4321, and a movable body. The exhaust valve 4321 is disposed on the housing, the movable body is disposed inside the housing, and the driving member 433 is connected to the movable body.

[0073] The second liquid storage tank 41 is sealed inside. One end of the vent pipe 431 is connected to the second liquid storage tank 41 and thus to the extraction pipe 42. A negative pressure is generated by the piston 432 and the drive component 433 to extract waste liquid from the coolant storage device. Specifically, the piston 432 includes a shell, an exhaust valve 4321, and a movable body. The other end of the vent pipe 431 is connected to the interior of the piston 432. When the drive component 433 drives the movable body to reciprocate within the shell, a negative pressure environment is gradually formed inside the second liquid storage tank 41, allowing waste liquid to be extracted into the second liquid storage tank 41 via the extraction pipe 42.

[0074] Furthermore, the driving component 433 is a crank-connecting rod mechanism, which includes: a flywheel 4331, a crank handle 4332, a first connecting rod 4333, a second connecting rod 4334, a third connecting rod 4335, and a limiting clamp 4336. The crank handle 4332 is located at the center of the flywheel 4331, driving the flywheel 4331 to rotate. The first connecting rod 4333, the second connecting rod 4334, and the third connecting rod 4335 are connected in sequence via a pulley 4337. The first connecting rod 4333 is also connected to the flywheel 4331, and the third connecting rod 4335 is also connected to the moving body. The limiting clamp 4336 is located outside the third connecting rod 4335. When the crank handle 4332 is turned, through the transmission of the three connecting rods, the third connecting rod 4335 can slide back and forth in the limiting clamp 4336 to ensure linear movement of the third connecting rod 4335, thereby driving the moving body to reciprocate within the outer shell.

[0075] In another embodiment, the pumping power mechanism 43 can also be a liquid pump.

[0076] In one embodiment, the waste liquid recovery assembly 4 further includes a drain mechanism 44, which includes a drain pipe 441 and a second regulating valve 442. The drain pipe 441 is connected to the second storage tank 41, and the second regulating valve 442 is disposed on the drain pipe 441.

[0077] like Figure 8 As shown, the connection between the drain pipe 441 and the second storage tank 41 is located at the bottom of the second storage tank 41, so that the waste liquid inside can be smoothly discharged from the drain pipe 441 under the action of gravity. The second regulating valve 442 is installed on the drain pipe 441 to control the opening and closing of the drain pipe 441 and the flow rate. With the drain mechanism 44 installed, the waste liquid inside the second storage tank 41 can be discharged in a timely manner when it is full.

[0078] In another embodiment, the draining mechanism 44 may not be provided. Instead, an opening is provided on the second liquid storage tank 41 and a cover is installed. Waste liquid can be discharged from the second liquid storage tank 41 by pouring.

[0079] The working process of the energy storage converter coolant treatment device provided in this embodiment is described below:

[0080] First, push the trolley 11 to the water-cooled energy storage converter cabinet, then activate the hydraulic cylinder 221 to lift the support platform 21 to a suitable working height. Next, connect the suction pipe 42 to the coolant storage device, and drive the piston 432 via the drive component 433 to gradually create negative pressure in the second storage tank 41, drawing the waste coolant from the coolant storage device into the second storage tank 41. After the waste coolant is drawn out, connect the filling pipe 32 to the coolant storage device, and then activate the power unit 331 (liquid pump) to add new coolant from the first storage tank 31 into the coolant storage device. After the coolant filling is completed, lower the support platform 21 via the hydraulic cylinder 221, and then move the trolley 11 to the next working location.

[0081] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
