[0021] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0022] As Figures 1 to 4 shown, an energy storage liquid cooling pipe test tooling of the present utility model includes a tooling frame 1, a lifting motor 2, a pulley frame 3, a branch component 4, and a test component 5. At least one branch component 4 is slidably connected to the tooling frame 1. The pulley frame 3 is connected to the tooling frame 1 and is located above the branch component 4. At least one lifting motor 2 is fixedly connected to the tooling frame 1. Each lifting motor 2 is connected to a branch component 4 through a rope 6. The rope 6 bypasses the pulley frame 3. A test component 5 is connected to each branch component 4. When the lifting motor 2 drives the branch component 4 to move to the same height as the branch inlet and outlet of the liquid cooling pipe 7 of the energy storage cabinet, the test component 5 is docked with the branch inlet and outlet of the liquid cooling pipe 7.

[0023] The tooling frame 1 is built by aluminum profiles. The overall equipment is very high, which is convenient for disassembly, installation and transportation. There is a guide groove 13 on the frame for the operation of the branch component 4. The branch component 4 slides up and down along the guide groove 13 and completes the lifting movement under the drive of the lifting motor 2. The test component 5 is used to dock with the branch of the liquid cooling pipe 7 in the energy storage cabinet and conduct tests. A test component 5 is installed on each branch component 4. Each lifting motor 2 individually controls a branch component 4 to move to the position of a branch of the liquid cooling pipe 7, and then docks the test component 5 with the branch of the liquid cooling pipe 7, without relying on manual adjustment of the connection between each branch component 4 and the branch of the liquid cooling pipe 7, improving the test efficiency and reducing the test labor intensity.

[0024] A plurality of pulleys 31 are provided on the pulley frame 3, and each pulley 31 corresponds to a rope 6. The pulley frame 3 is used to install the pulleys 31. The rope 6 is a steel wire rope 6, which is used to connect the motor and the branch component 4. The pulley 31 changes the running direction of the steel wire rope 6, converts the rope 6 direction of the lifting motor 2 into the vertical direction connected to the branch component 4, so as to realize the lifting control of the branch component 4 by the lifting motor 2.

[0025] The tooling frame 1 is provided with a motor mounting plate 11, and at least one lifting motor 2 is connected to the motor mounting plate 11. Each lifting motor 2 is composed of a reduction motor 21 and a speed governor 22. The motor mounting plate 11 is used to mount the reduction motor 21, the speed governor 22, etc. The reduction motor 21 is composed of a motor and a reducer, and controls the forward and reverse rotation of the motor to realize the rise and fall of the branch component 4; the speed governor 22 is used to adjust the lifting speed of the motor. The reduction motor 21 and the speed governor 22 corresponding to every five layers of branch components 4 are integrally installed, and a protective cover 12 is installed to protect the speed governor 22.

[0026] As Figure 5 shown, the branch component 4 includes a branch bottom plate 41 and a guide wheel module 42. The tooling frame 1 is provided with a guide groove 13. Multiple groups of guide wheel modules 42 are connected to the side of the branch bottom plate 41, and each group of guide wheel modules 42 is slidably connected to the guide groove 13. The multiple groups of guide wheel modules 42 are distributed around the branch bottom plate 41, which can ensure that the branch bottom plate 41 smoothly rises and falls along the guide groove 13 and makes the sliding of the branch bottom plate 41 smoother.

[0027] As Figure 6 shown, the guide wheel module 42 includes a bearing bracket 43, a bearing 44, and a retaining ring 45. The bearing bracket 43 is connected to the branch bottom plate 41. The bearing bracket 43 is provided with a bearing bracket support column 46. The inner ring of the bearing 44 is connected to the bearing bracket support column 46, and the outer ring of the bearing 44 is slidably connected to the guide groove 13. The retaining ring 45 is connected to the bearing bracket support column 46 and blocks the outside of the bearing 44. The guide wheel module 42 uses a ball bearing 44 as a sliding part to make the branch component 4 run smoothly. Multiple bearings 44 are evenly distributed on each bearing bracket 43, making the support of the bearing bracket 43 more balanced and ensuring the stability of sliding. The retaining ring 45 restricts the position of the bearing 44 on the bearing bracket support column 46 to prevent the bearing 44 from falling off the bearing bracket support column 46.

[0028] The branch component 4 further includes a travel pointer 47. The travel pointer 47 is connected to the branch bottom plate 41. The tooling frame 1 is provided with a scale 14, and the travel pointer 47 aligns with the position of the scale 14. The scales 14 are installed on both sides of the tooling frame 1, and the scale 14 is selected as a steel ruler. When the branch component 4 slides on the tooling frame 1, the travel pointer 47 will slide up and down, thus corresponding to the scales at different positions on the steel ruler, and is used to indicate the travel of the branch component 4.

[0029] The branch component 4 further includes a photoelectric switch 48. The photoelectric switch 48 is connected to the branch bottom plate 41. The photoelectric switch 48 is used to detect the distance between the upper and lower branch bottom plates 41. When the branch bottom plate 41 rises and falls, if the two branch bottom plates 41 are relatively close, the photoelectric switch 48 will be triggered, thereby stopping the drive of the corresponding lifting motor 2 to avoid the collision of the two branch components 4.

[0030] The test assembly 5 includes a flow regulating valve 51, a flow meter 52, a hose 55, and an adapter 54. The flow regulating valve 51 and the flow meter 52 are installed on the branch bottom plate 41. The adapter 54 at the fluid inlet end, the flow regulating valve 51, the flow meter 52, and the adapter 54 at the fluid outlet end are sequentially connected by the hose 55. The adapter 54 at the fluid inlet end and the adapter 54 at the fluid outlet end are respectively docked with the branch inlet and outlet of the liquid cooling pipe 7 of the energy storage cabinet.

[0031] The test assembly 5 further includes a differential pressure sensor 53. The differential pressure sensor 53 is connected to the branch bottom plate 41. Both ends of the differential pressure sensor 53 are respectively connected to the adapter 54 at the fluid inlet end and the adapter 54 at the fluid outlet end by the hose 55.

[0032] The branch bottom plate 41 is a place for installing test systems such as the flow regulating valve 51, the flow meter 52, and the differential pressure sensor 53. Among them, the flow regulating valve 51 is used to adjust the pipe diameter; the flow meter 52 is used to measure the flow rate of the fluid medium passing through each branch; the differential pressure sensor 53 is used to measure the differential pressure value between the front end of the flow regulating valve 51 and the rear end of the flow meter 52. The hose 55 uses a silicone hose 55, and the adapter 54 is used to dock with the inlet and outlet of the liquid cooling pipe 7.

[0033] A rope bracket 49 is provided on the branch bottom plate 41. One end of the rope 6 is connected to the rope bracket 49, and the other end of the rope 6 is connected to the output end of the lifting motor 2. The rope bracket 49 is an L-shaped bracket, which is used to connect the branch bottom plate 41 and the wire rope 6 and serves as the support point for the lifting motor 2 to drive the branch assembly 4.

[0034] Function of the branch assembly 4: Compare the entire branch assembly 4 to the liquid cooling plate in the actual energy storage battery cabinet. By adjusting the opening degree of the valve core of the flow regulating valve 51, simulate the flow rate and flow resistance parameters of the coolant passing through the battery liquid cooling plate in the energy storage cabinet, and verify the performance of the energy storage liquid cooling pipe 7.

[0035] Operating steps of this energy storage liquid cooling pipe test tooling:

[0036] Fix the energy storage liquid cooling pipe 7 on both sides of the tooling frame 1; operate the lifting motor 2 to rotate through the upward control button, and the wire rope 6 drives the branch assembly 4 to rise. According to the rising speed, adjust the speed regulator 22 to make the rising speed slow and stable. When the height of the adapter 54 on the branch assembly 4 is the same as the height of the branch inlet and outlet of the liquid cooling pipe 7, stop operating the motor button and insert the branch of the liquid cooling pipe 7 into the adapter 54; operate each lifting motor 2 according to the above process, and sequentially adjust the height of each branch assembly 4 from top to bottom, so that each branch of the liquid cooling pipe 7 is connected to a branch assembly 4, and then a fluid medium is introduced into the liquid cooling pipe 7 for testing.

It cannot be determined that the specific implementation of the present utility model is only limited to these descriptions. For those of ordinary skill in the technical field to which the present utility model pertains, without departing from the concept of the present utility model, several simple deductions or substitutions can still be made, and all should be regarded as belonging to the protection scope of the present utility model.
