Description

Technical Field

[0001] The invention relates to the technical field of battery storage boxes, and in particular to a colloidal battery storage box for an off-grid solar energy storage power generation system. Background Art

[0002] The solar off-grid energy storage power generation system uses solar panels to convert solar energy into electrical energy under sunlight, and supplies power to the load through a solar charge and discharge controller while charging the battery. In rainy weather or when there is no sunlight, the solar charge and discharge controller supplies power to the DC load through the battery pack. At the same time, the battery also directly supplies power to the independent inverter, which is then converted into AC power to supply power to the AC load.

[0003] However, the colloidal batteries stored in the storage box will generate heat during the cyclic charge and discharge process, so the colloidal batteries in the storage box need to be ventilated and cooled. In the prior art, in order to prevent moisture in the air from entering the storage box, hygroscopic materials are usually installed in the air inlet to absorb moisture in the air. However, long-term use of the hygroscopic material will cause moisture accumulation and easily form a saturated state. This situation will cause the hygroscopic material to be airtight and in a sealed state, making it impossible to ventilate the storage box well and cool the batteries in the storage box. Since the air cannot circulate, the temperature inside the storage box will increase, thereby shortening the life of the colloidal battery. For this reason, a colloidal battery storage box for a solar off-grid energy storage power generation system is proposed. Summary of the invention

DETAILED DESCRIPTION

[0016] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] Please refer to Figure 1-Figure 8 The present invention provides a technical solution: a colloidal battery storage box for a solar off-grid energy storage power generation system, comprising a box body 1, side panels 11 are provided on both sides of the box body 1, a plurality of storage racks 2 distributed at equal intervals are fixedly installed on the inner wall of the box body 1, a battery body 3 is installed on the top of the plurality of storage racks 2, an air intake mechanism 4, a circulation drying mechanism 5 and an exhaust mechanism 6 are fixedly installed on one side of the side panel 11 close to the storage rack 2, a connecting pipe 8 is connected between the circulation drying mechanism 5 and the exhaust mechanism 6, a driving mechanism 7 is provided between the air intake mechanism 4 and the exhaust mechanism 6, the driving mechanism 7 is used to draw external cold air into the circulation drying mechanism 5 through the air intake mechanism 4, and then transport it to the inside of the box body 1 after drying to cool the battery body 3, and discharge the hot air inside the box body 1 through the exhaust mechanism 6 and the connecting pipe 8, and the hot air discharged through the connecting pipe 8 dries the moisture in the circulation drying mechanism 5.

[0018] The air intake mechanism 4 includes a round tube 2 43 that passes through the side plate 11 and is fixedly connected to the side plate 11, and a cross frame 41 fixedly installed on the side plate 11 near the storage rack 2. A round tube 1 42 is fixedly installed through the cross frame 41. An elbow 44 is fixedly sleeved on the round tube 2 43. A round tube 3 45 is fixedly installed on the end of the elbow 44 away from the round tube 2 43. A fixed plate 1 48 is fixedly installed in the round tube 3 45. A piston plate 1 46 is slidably installed in the round tube 1 42. A plurality of one-way valves 2 49 distributed in a circular array are fixedly installed through the fixed plate 1 48. A plurality of one-way valves 1 47 distributed in a circular array are fixedly installed through the piston plate 1 46.

[0019] The circulating drying mechanism 5 includes a baffle plate 1 51 and a baffle plate 2 52 fixedly mounted on the side plate 11 close to the storage rack 2. The top end of the connecting pipe 8 passes through the baffle plate 2 52 and is fixedly connected to the baffle plate 2 52. A motor 1 59 is fixedly mounted on the top of the cross frame 41. A connecting plate 54 is fixedly mounted on the output shaft of the motor 1 59. A fixed pipe 1 55 and a fixed pipe 2 56 are fixedly mounted on both sides of the connecting plate 54. A dehumidifier 1 57 and a dehumidifier 2 58 are fixedly mounted in the fixed pipe 1 55 and the fixed pipe 2 56. An air outlet pipe 53 is fixedly mounted on the baffle plate 1 51. The air outlet pipe 53 passes through the side plate 11 and is fixedly connected to the side plate 11.

[0020] Furthermore, by starting the motor 1 59, the connecting plate 54 can be driven to rotate, and the rotation of the connecting plate 54 will cause the fixed tube 1 55 and the fixed tube 2 56 to exchange positions. When the fixed tube 2 56 and the round tube 1 42 and the round tube 3 45 are coaxial, the dehumidifying element 2 58 can adsorb and dehumidify the cold air entering the box body 1. At this time, the hot air inside the box body 1 discharged from the connecting pipe 8 will flow through the fixed tube 1 55 and dry the dehumidifying element 1 57. The dehumidifying element 1 57 and the dehumidifying element 2 58 are made of recyclable materials. When the fixed tube 1 55 and the circular tubes 1 42 and 3 45 are coaxial, the dehumidifying element 1 57 can adsorb and dehumidify the cold air entering into the box body 1. At this time, the hot air inside the box body 1 discharged from the connecting tube 8 will flow through the fixed tube 2 56 and dry the dehumidifying element 2 58. Therefore, it is only necessary to start the motor 1 59 regularly to replace the positions of the fixed tube 1 55 and the fixed tube 2 56, so that the dehumidifying element 1 57 and the dehumidifying element 2 58 can always have better adsorption and dehumidification capabilities.

[0021] The driving mechanism 7 includes a transverse seat 71 fixedly mounted on the side of the side plate 11 close to the storage rack 2, a vertical seat 72 fixedly mounted on the side of the transverse seat 71 away from the side plate 11, and two limit blocks 73 fixedly mounted on the side of the vertical seat 72 away from the transverse seat 71, and a round rod 1 74 and a round rod 2 75 are respectively slidably mounted on the two limit blocks 73, the top of the round rod 2 75 is fixedly connected to the bottom of the piston plate 1 46, and the ends of the round rods 1 74 and 2 75 close to each other are fixedly mounted with the same rectangular frame 76, a rotating shaft 77 is rotatably mounted on the vertical seat 72, a rotating plate 78 is fixedly mounted on the end of the rotating shaft 77 close to the rectangular frame 76, a rotating column 79 is rotatably mounted on the side of the rotating plate 78 away from the rotating shaft 77, and the rotating column 79 is rollingly mounted in the rectangular frame 76, and a motor 2 710 is fixedly mounted on the top of the transverse seat 71, and the output shaft of the motor 2 710 is fixedly connected to the end of the rotating shaft 77.

[0022] The exhaust mechanism 6 includes a horizontal plate 61 fixedly installed on the side of the side plate 11 close to the storage rack 2, a circular tube 4 62 is fixedly installed on the top of the horizontal plate 61, a fixed plate 2 65 and a piston plate 2 63 are fixedly installed in the circular tube 4 62, the bottom end of the round rod 1 74 is fixedly connected to the top of the piston plate 2 63, a plurality of one-way valves 3 64 distributed in a circular array are fixedly installed through the piston plate 2 63, a plurality of one-way valves 4 66 distributed in a circular array are fixedly installed through the fixed plate 2 65, the bottom end of the connecting pipe 8 passes through the horizontal plate 61 and is fixedly connected to the horizontal plate 61, and the bottom end of the connecting pipe 8 is connected to the circular tube 4 62.

[0023] One-way valve 1 47 , one-way valve 2 49 , one-way valve 3 64 and one-way valve 4 66 are arranged in the same direction.

[0024] Furthermore, one-way valve one 47, one-way valve two 49, one-way valve three 64 and one-way valve four 66 are arranged in the same direction so that the airflow can only flow from top to bottom in the one-way valve one 47, one-way valve two 49, one-way valve three 64 and one-way valve four 66.

[0025] A filter plate 431 is fixedly installed in the circular tube 43, a scraper 432 is rotatably installed on the side of the filter plate 431 away from the elbow 44, a circular shaft 433 is rotatably installed through the filter plate 431, one end of the circular shaft 433 is fixedly connected to the scraper 432, and an impeller 434 is fixedly installed on the other end of the circular shaft 433.

[0026] Furthermore, when the external cold air flows through the circular tube 43 and enters the interior of the box 1, it will drive the impeller 434 to rotate. The impeller 434 rotates and drives the scraper 432 to rotate through the circular shaft 433. The rotation of the scraper 432 can clean the dust attached to the filter plate 431.

[0027] The top and bottom ends of the fixed tube 1 55 and the fixed tube 2 56 are both embedded with sealing rings, and the cross section of the sealing rings is circular or trapezoidal.

[0028] Furthermore, the sealing ring with a circular or trapezoidal cross-section can make it easier for the fixed tube 1 55 and the fixed tube 2 56 to be inserted between the circular tube 1 42 and the circular tube 3 45 and the baffle 1 51 and the baffle 2 52 and maintain the seal.

[0029] In this embodiment, when in use, the second motor 710 is started to drive the rotating shaft 77 to rotate, and the rotating shaft 77 then drives the rotating column 79 to rotate through the rotating plate 78. As the rotating column 79 rotates with the rotating shaft 77 as the center, it will drive the rectangular frame 76 to move up and down. When the rectangular frame 76 drives the second round rod 75 to move downward, the second round rod 75 will drive the piston plate 1 46 to move downward. At this time, the external cold air will enter the elbow 44 through the second round tube 43 and pass through multiple one-way valves 2 49 to enter between the fixed plate 1 48 and the piston plate 1 46. In this process, Figure 5 As shown, the dehumidifying element 2 58 can absorb the moisture in the cold air entering between the fixed plate 1 48 and the piston plate 1 46; As mentioned above, when the rectangular frame 76 drives the round rod 2 75 to move upward, the round rod 2 75 will drive the piston plate 1 46 to move upward. During the upward movement of the piston plate 1 46 , the dry cold air between the fixed plate 1 48 and the piston plate 1 46 will pass through the multiple one-way valves 1 47 and enter the interior of the box body 1; When the rectangular frame 76 drives the round rod 1 74 to move upward, the round rod 1 74 will drive the piston plate 2 63 to move upward. At this time, the hot air inside the box body 1 will pass through multiple one-way valves 3 64 and enter between the piston plate 2 63 and the fixed plate 2 65. Then, when the rectangular frame 76 drives the round rod 1 74 to move downward, the round rod 1 74 will drive the piston plate 2 63 to move downward, and the hot air between the piston plate 2 63 and the fixed plate 2 65 will pass through multiple one-way valves 4 66 and enter the connecting pipe 8. After the hot air flows through the connecting pipe 8, Figure 5 As shown, the hot air will flow into the fixed pipe 55 and finally be discharged from the outlet pipe 53 during the process of being discharged through the connecting pipe 8. The hot air will heat the dehumidification element 57 during the process of flowing through the fixed pipe 55, so that the dehumidification element 57 adsorbed with moisture can be dried.
