Abstract
Description
Technical Field
[0001] The utility model relates to a power cord disconnection device, belonging to the technical field of safety protection. Background Art
[0002] With the rapid development of new energy technologies, high-density and large-capacity storage batteries are not only widely used in new energy vehicles to supply power to the vehicles, but also widely applied in the fields of wind power generation and photovoltaic power generation technologies to temporarily store the electric energy that cannot be absorbed by the grid in time during the peak power generation period.
[0003] At the current technical level, high-density and large-capacity batteries still have not completely solved the problem of combustion and explosion. We can often see reports of various safety accidents caused by battery combustion and explosion.
[0004] Before various batteries are formally put into production and during the experimental process, strict tests on various performances of the batteries are required. And when such batteries are being tested, the possibility of combustion and explosion is even greater.
[0005] The testing laboratories for batteries are equipped with various expensive instruments and equipment, and even the laboratories themselves are built with expensive special materials. If a battery combustion and explosion occurs during the test and there is no immediate and effective treatment method, the entire laboratory together with the instruments and equipment can be burned down within a very short time. And fire extinguishing measures such as using fire extinguishers and watering have almost no effect on the combustion and explosion of the battery itself. Since large-capacity batteries weigh several hundred kilograms or even several tons (the weight of large-scale wind and photovoltaic power energy storage batteries), and there are thick power cords connecting them to the experimental equipment, it is very difficult for people in a hurry to move them out of the laboratory within a short period of several seconds when a combustion and explosion occurs. Summary of the Utility Model
[0006] To solve the above problems, the applicant has developed a system for preventing the combustion and explosion of large-capacity storage batteries from burning down the testing equipment during testing (patent protection is applied for on the same day). The system includes a van-type cabinet for placing the storage battery and a traction mechanism. When a combustion and explosion occurs, the traction mechanism drags the van-type cabinet out of the laboratory door to an open space, so that the storage battery in the van-type cabinet burns in the open space to protect the laboratory and the experimental equipment, and minimize the losses caused by the combustion and explosion of the large-capacity storage battery. This system requires that the power cord between the storage battery and the testing equipment must be quickly disconnected before the van-type cabinet is towed.
[0007] The technical problem to be solved by the utility model is: to solve the problem of quickly disconnecting the power cord between the storage battery and the testing equipment for the above system.
[0008] In view of the above problems, the technical solution proposed by the utility model is:
[0009] A power cord disconnection device includes a pile body, a pressing member capable of quickly relieving pressure, an output integrated block and an input integrated block having a plurality of circuit blocks. The upper part of the pile body has a lap cavity penetrating from front to back. The pressing member is arranged in the lap cavity. Each circuit block of the output integrated block and the input integrated block is separated by an insulator. The rear end of the output integrated block and the front end of the input integrated block are lapped in the lap cavity and are pressed by the pressing member. Each circuit block of the output integrated block is respectively lapped and communicated with each circuit block of the input integrated block. The front end of the output integrated block and the rear end of the input integrated block are respectively connected to a storage battery and a detection device. By relieving the pressure applied by the pressing member, the output integrated block can be disengaged from the pile body.
[0010] Each circuit block of the output integrated block has at least an exposed output lap surface in the same plane in the lap area where the output integrated block and the input integrated block are lapped. Each circuit block of the input integrated block has at least an exposed input lap surface in the same plane in the lap area where the input integrated block and the output integrated block are lapped.
[0011] The pressing member includes a convex rib shaft with a convex rib on one side. The convex rib shaft is arranged at the lower part of the lap cavity of the pile body. One end of the convex rib shaft is provided with a turning arm. The output integrated block and the input integrated block are lapped up and down above the convex rib shaft. By rotating the convex rib shaft, the output integrated block and the input integrated block are pressed by the convex rib. Rotating the convex rib shaft by 30 - 60° can relieve the pressure on the output integrated block and the input integrated block.
[0012] A force balance cushion block is added between the lapped output integrated block and input integrated block and the convex rib shaft. The force balance cushion block includes two hard blocks up and down and a rubber layer located between the two hard blocks.
[0013] The turning arm includes a manual turning arm, and the manual turning arm is arranged at one end of the convex rib shaft exposed outside the pile body.
[0014] The turning arm further includes a linkage turning arm connected to the linkage traction mechanism of the system traction device. The linkage turning arm under working conditions inclines downward and backward, and has a notch with an opening backward at the lower end.
[0015] A notch communicating from front to back is opened on the pile body in the middle below the lap cavity. The upper end of the linkage turning arm is fixed in the middle of the convex rib shaft, and the whole convex rib shaft can swing back and forth in the notch. Beneficial effects
[0016] 1. When an explosion occurs, the power cord can be quickly disconnected, avoiding the power cord connected to the detection device from forming an entanglement when the van cabinet is dragged out.
[0017] 2. The operation is simple and the response is timely. Just rotate the turning arm by 30 - 60° to relieve the pressure on the output integrated block and the input integrated block. Description of the drawings

Specific embodiments
[0025] The following further describes the present invention in conjunction with the embodiments and the drawings: Embodiment 1
[0026] As Figure 1As shown in FIG. 4, a power cord disconnection device 100 includes a pile body 1, a pressing member capable of quickly relieving pressure, an output integrated block 2 having a plurality of circuit blocks 201, and an input integrated block 3. The upper part of the pile body 1 has a lap cavity 11 that penetrates from front to back. The pressing member is arranged in the lap cavity 11. The circuit blocks 201 of the output integrated block 2 and the input integrated block 3 are separated by insulators 203. The rear end of the output integrated block 2 and the front end of the input integrated block 3 are lapped in the lap cavity 11 and are pressed by the pressing member. The circuit blocks 201 of the output integrated block 2 are respectively lapped and communicated with the circuit blocks 201 of the input integrated block. The front end of the output integrated block 2 and the rear end of the input integrated block 3 are respectively connected to a storage battery 400 and a detection device through rubber power cords 202. When an explosion occurs, quickly relieve the pressure applied by the pressing member, so that the output integrated block 2 can be disengaged from the pile body 1, and the output integrated block 2 can be towed out of the laboratory door by a towing device together with the van-type cabinet 300 where the storage battery is placed. In this way, the power cord 200 connected to the detection device is prevented from hindering the towing of the van-type cabinet.
[0027] Here, the rear end of the output integrated block 2 and the front end of the input integrated block 3 are lapped. The circuit blocks 201 of the output integrated block 2 are respectively lapped and communicated with the circuit blocks 201 of the input integrated block. The front end of the output integrated block 2 and the rear end of the input integrated block 3 are respectively connected to the storage battery 400 and the detection device through rubber power cords 202, thereby forming the power cord 200 from the storage battery 400 to the detection device.
[0028] Each of the circuit blocks 201 of the output integrated block 2 has an exposed output lap surface 21 in the same plane at least in the lap area where the output integrated block 2 and the input integrated block 3 are lapped. Each of the circuit blocks 201 of the input integrated block 3 has an exposed input lap surface 31 in the same plane at least in the lap area where the input integrated block 3 and the output integrated block 2 are lapped, which is conducive to the lap and communication between the circuit blocks 201 of the output integrated block 2 and the circuit blocks 201 of the input integrated block respectively.
[0029] As Figure 1 、 5 As shown in FIGS. 5 and 6, the pressing member includes a convex rib shaft 4 with a convex rib 41 on one side. The convex rib shaft 4 is arranged at the lower part of the lap cavity 11 of the pile body 1. One end of it is provided with a turning arm 5. The output integrated block 2 and the input integrated block 3 are lapped up and down above the convex rib shaft 4. By rotating the convex rib shaft 4, the output integrated block 2 and the input integrated block 3 are pressed by the convex rib 41. Rotating the convex rib shaft 4 by 30 - 60° can relieve the pressure on the output integrated block 2 and the input integrated block 3. In this way, only by rotating the convex rib shaft 4 by an angle can the pressure between the output integrated block 2 and the input integrated block 3 be relieved, which can meet the rapid response requirements when an explosion occurs.
[0030] As Figure 2As shown, a force balance cushion block 6 is provided between the lapped output integrated circuit block 2 and input integrated circuit block 3 and the rib shaft 4. The force balance cushion block 6 includes two upper and lower hard blocks 61 and a rubber layer 62 located between the two hard blocks 61. Since the rib 41 only provides a single force-bearing pressing line, after using the force balance cushion block 6, the entire lapped portion of the output integrated circuit block 2 and input integrated circuit block 3 can be stressed through the force balance block. At the same time, the rubber layer 62 is provided to not only play an insulating role but also use its elasticity to keep a constant pressure on the output integrated circuit block 2 and input integrated circuit block 3.
[0031] As Figure 2 , 5 , 6 shows that the 5 - arm 5 includes a manual arm 51. The manual arm 51 is provided at one end of the rib shaft 4 exposed outside the pile body 1. When necessary, the manual arm 51 can be pushed by hand to rotate by an angle, thus relieving the pressure exerted by the rib shaft 4 on the output integrated circuit block 2 and input integrated circuit block 3, meeting the requirement of quickly separating the output integrated circuit block 2 and input integrated circuit block 3.
[0032] Embodiment 2
[0033] As Figure 1 , 2 , 5, 6 show that the arm 5 further includes a linkage arm 52 connected to the linkage traction mechanism of the system traction device. The linkage arm 52 under working conditions is inclined downward and backward, and the lower end has a notch 521 with an opening facing backward. Additionally, a linkage cable 7 is provided in the traction device, such that the linkage cable 7 is hung in the notch 521 at the lower end of the linkage arm 52 and can automatically slip off when the linkage arm 52 rotates to be inclined forward. When an explosion occurs, the traction device first pulls the linkage arm 52 through the linkage cable 7 to rotate until the rib shaft 4 relieves the pressure on the output integrated circuit block 2, causing the output integrated circuit block 2 to become loose and then dragging the van cabinet 300, which is very beneficial for a quick response in the event of an explosion.
[0034] Further, a notch 12 communicating front and back is provided on the pile body 1 in the middle below the lapping cavity 11. The upper end of the linkage arm 52 is fixed in the middle of the rib shaft 4, and the entire rib shaft 4 can swing back and forth in the notch 12.
[0035] The above embodiments are only used to describe the present invention more clearly and should not be regarded as limiting the protection scope covered by the present invention. Any equivalent form of modification should be regarded as falling within the protection scope covered by the present invention.
