Description

Technical Field

[0001] This utility model relates to the field of groundwater detection technology, specifically a waterproof battery pack for groundwater detection. Background Technology

[0002] Lithium iron phosphate (LFP) batteries are a type of lithium-ion battery. Their positive electrode material is lithium iron phosphate, the negative electrode is typically graphite, the electrolyte is an organic solvent containing lithium salts, and the separator prevents direct contact between the positive and negative electrodes. With the increasing popularity of LFP batteries, they are found in more and more applications, such as groundwater detection. Traditional battery packs often have a sealed outer shell to achieve waterproofing. However, batteries generate high temperatures during use, and the sealed shell traps these temperatures inside, affecting battery performance. To address this issue, a waterproof battery pack for groundwater detection has been proposed.

[0003] A waterproof battery pack, as disclosed in authorization announcement number CN220491984U, includes a battery pack body, a mounting box, and a cover. The battery pack body is located inside the mounting box. The lower side of the cover and the upper side of the mounting box are both L-shaped structures, and the L-shaped structure on the lower side of the cover can be engaged with the L-shaped structure on the upper side of the mounting box. A sealing strip is fixed to the end of the L-shaped structure on the lower side of the cover that contacts the mounting box. A sealing groove adapted to the sealing strip is provided at the L-shaped structure on the upper side of the mounting box. Water-absorbing cotton is fixed to the inner side of the top of the mounting box. A cooling fan is provided at the center of the top of the cover and at the bottom of one side of the mounting box. A drying chamber is installed inside the cooling fan on the mounting box, and a drying structure is provided inside the drying chamber.

[0004] Although it achieves sealing at the connection point through the sealing strip and sealing groove at the junction of the cover and the mounting box to prevent moisture from entering, the cooling fan can dissipate heat from the battery pack body to prevent the internal temperature of the mounting box from being too high and affecting the operation of the battery pack body.

[0005] However, this does not solve the problem that existing waterproof battery packs are not conducive to convenient and stable battery installation, nor to comprehensive heat conduction and cooling, thus affecting the battery's heat dissipation effect. Utility Model Content

[0006] The purpose of this invention is to provide a waterproof battery pack for groundwater detection, in order to solve the problems mentioned in the background art, such as the inconvenience of convenient and easy positioning of the battery to provide stable support, the difficulty in conducting heat and cooling the battery in all directions, and the impact on the battery's heat dissipation effect.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a waterproof battery pack for groundwater detection, comprising a sealing shell and a shell cover. The top of the sealing shell is provided with a shell cover, which is connected to the sealing shell by a sealant. A base is provided inside the sealing shell. Multiple sets of lithium iron phosphate batteries are provided at equal intervals on the top of the base. A top plate is provided above the base. Two sets of connecting buckles are symmetrically provided at the bottom of the top plate. Two sets of insertion ports are symmetrically provided on the side wall of the base. The connecting buckles are slidably connected to the insertion ports and can be snapped into the interior of the insertion ports. Multiple sets of connecting pieces are provided on the top of the top plate, and the lithium iron phosphate batteries are connected in series through the connecting pieces.

[0008] Preferably, heat dissipation fins are symmetrically arranged at the top of the base on both sides of the lithium iron phosphate battery, and heat dissipation copper plates are symmetrically installed on the side walls of the heat dissipation fins.

[0009] Preferably, the sidewalls of the heat dissipation copper plate are provided with multiple sets of protrusions at equal intervals, and the heat dissipation copper plate is connected to the sealing shell by sealant.

[0010] Preferably, a side plate is provided at the top of the base on one side of the heat dissipation fins, and multiple sets of spacers with equal spacing are provided between the two sets of heat dissipation fins. The spacers are attached to the lithium iron phosphate battery and separate the lithium iron phosphate battery.

[0011] Preferably, the inner walls of the heat dissipation fins are symmetrically provided with first T-shaped grooves, and the two sides of the side plate are provided with second T-shaped strips, and the second T-shaped strips are slidably connected to the first T-shaped grooves.

[0012] Preferably, a first T-shaped strip is provided on both sides of the partition plate, and multiple sets of second T-shaped grooves with equal spacing are provided on the inner wall of the side plate. The first T-shaped strips and the second T-shaped grooves are slidably connected, and the partition plate, heat dissipation fins and side plates are all made of aluminum.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the waterproof battery pack not only realizes convenient and fixed installation of the battery to provide stable support for the battery, but also facilitates all-round heat conduction and cooling of the battery, and ensures normal operation of the battery and improves the heat dissipation effect of the battery.

[0014] Install the base inside the sealed shell. Remove the side plate, align the second T-shaped strip with the first T-shaped groove, and move the side plate. The side plate will move the second T-shaped strip inside the first T-shaped groove, connecting the two sets of heat dissipation fins to form a frame. Then, remove the spacer plate, which will move the first T-shaped strip inside the second T-shaped groove. Install the spacer plate inside the frame to form a spaced heat dissipation frame. Then, install the frame on the base and stack multiple sets of lithium iron phosphate batteries in the frame spacing. Remove the top plate, which will move the connecting buckle and lock it inside the socket to connect the top plate to the base, thus fixing the lithium iron phosphate batteries between the top plate and the base. Then, connect the connecting pieces to the terminals of the lithium iron phosphate batteries in sequence, forming a series connection between the multiple sets of lithium iron phosphate batteries. At the same time, place the heat dissipation copper plate from the outside of the sealed shell. The copper heat sink is inserted into the sealed shell and connected to the heat dissipation fins. It is then connected to the sealed shell via sealant. After applying sealant to the edges of the shell cover, it is placed on top of the sealed shell to complete the seal, creating a sealed environment to prevent water ingress and damage when the battery pack operates in groundwater. The lithium iron phosphate battery generates heat during operation. This heat is transferred to the surface of the copper heat sink through the spacer and heat dissipation fins. The copper heat sink has multiple sets of protrusions on its surface, increasing the contact area between the copper heat sink and the groundwater, thus transferring internal heat to the groundwater. This provides thermal conductivity and cooling for the lithium iron phosphate battery, ensuring its normal operation. The design allows for convenient and stable battery installation, facilitating comprehensive thermal conductivity and cooling, ensuring normal battery operation, and improving battery heat dissipation.

[0023] Example 1

[0024] Please see Figure 1-4 This utility model provides an embodiment of a waterproof battery pack for groundwater detection, including a sealing shell 1 and a shell cover 2. The top of the sealing shell 1 is provided with the shell cover 2, and the shell cover 2 is connected to the sealing shell 1 by sealant. The interior of the sealing shell 1 is provided with a base 7. The top of the base 7 is provided with multiple sets of lithium iron phosphate batteries 6 at equal intervals. The top of the base 7 is provided with a top plate 10. The bottom of the top plate 10 is symmetrically provided with two sets of connecting buckles 9. The side wall of the base 7 is symmetrically provided with two sets of sockets 8, and the connecting buckles 9 are slidably connected to the sockets 8. The connecting buckles 9 can be inserted into the interior of the sockets 8. The top of the top plate 10 is provided with multiple sets of connecting pieces 5, and the lithium iron phosphate batteries 6 are connected in series through the connecting pieces 5.

[0025] The top of the base 7 on both sides of the lithium iron phosphate battery 6 is symmetrically provided with heat dissipation fins 4, and heat dissipation copper plates 3 are symmetrically installed on the side walls of the heat dissipation fins 4.

[0026] The sidewalls of the heat dissipation copper plate 3 are provided with multiple sets of protrusions 17 at equal intervals, and the heat dissipation copper plate 3 is connected to the sealing shell 1 by sealant. The top of the base 7 on one side of the heat dissipation fin 4 is provided with a side plate 15, and multiple sets of spacers 12 at equal intervals are provided between the two sets of heat dissipation fins 4. The spacers 12 are attached to the lithium iron phosphate battery 6 and separate the lithium iron phosphate battery 6.

[0027] The inner wall of the heat dissipation fins 4 is symmetrically provided with first T-shaped grooves 11, and the two sides of the side plate 15 are provided with second T-shaped strips 16, and the second T-shaped strips 16 are slidably connected to the first T-shaped grooves 11.

[0028] Both sides of the partition plate 12 are provided with first T-shaped strips 13, and the inner wall of the side plate 15 is provided with multiple sets of second T-shaped grooves 14 at equal intervals. The first T-shaped strips 13 and the second T-shaped grooves 14 are slidably connected. The partition plate 12, the heat dissipation fins 4, and the side plate 15 are all made of aluminum.

[0029] Install the base 7 inside the sealed shell 1. Remove the side plate 15, align the second T-shaped strip 16 with the first T-shaped groove 11, and move the side plate 15. The side plate 15 will drive the second T-shaped strip 16 to move inside the first T-shaped groove 11, connecting the two sets of heat dissipation fins 4 to form a frame. Then, remove the spacer plate 12, which will drive the first T-shaped strip 13 to move inside the second T-shaped groove 14. Install the spacer plate 12 inside the frame to form a heat dissipation frame with intervals. Then, install the frame on the base 7 and stack multiple sets of lithium iron phosphate batteries 6 in the intervals of the frame. Remove the top plate 10, which will drive the connecting buckle 9 to move and lock the connecting buckle 9 inside the socket 8, connecting the top plate 10 to the base 7. This will fix the lithium iron phosphate batteries 6 between the top plate 10 and the base 7. Then, connect the connecting piece 5 to the terminals of the lithium iron phosphate batteries 6 in sequence, forming a series connection between the multiple sets of lithium iron phosphate batteries 6. Simultaneously, the heat dissipation copper plate 3 is inserted from the outside of the sealing shell 1 into the interior of the sealing shell 1 and connected to the heat dissipation fins 4. The heat dissipation copper plate 3 is connected to the sealing shell 1 through sealant. After applying sealant to the edge of the shell cover 2, the shell cover 2 is placed on the sealing shell 1 to complete the seal, creating a sealed environment inside to prevent water ingress and damage when the battery pack is working in groundwater. The lithium iron phosphate battery 6 generates heat during operation. This heat is transferred to the surface of the heat dissipation copper plate 3 through the heat conduction of the spacer plate 12 and the heat dissipation fins 4. Because the surface of the heat dissipation copper plate 3 is provided with multiple sets of protrusions 17, the contact area between the heat dissipation copper plate 3 and the groundwater can be increased to transfer the internal heat to the groundwater, thereby conducting heat and cooling the lithium iron phosphate battery 6 to ensure the normal operation of the battery. This achieves convenient and limited installation of the battery, provides stable support for the battery, facilitates all-round heat conduction and cooling of the battery, ensures the normal operation of the battery, and improves the heat dissipation effect of the battery.

[0030] Working principle: Install the base 7 inside the sealed shell 1. Remove the side plate 15, align the second T-shaped strip 16 with the first T-shaped groove 11, and move the side plate 15. The side plate 15 drives the second T-shaped strip 16 to move inside the first T-shaped groove 11, connecting the two sets of heat dissipation fins 4 to form a frame. Then, remove the spacer plate 12, which drives the first T-shaped strip 13 to move inside the second T-shaped groove 14. Install the spacer plate 12 inside the frame to form a heat dissipation frame with intervals. Then, install the frame on the base 7 and place multiple sets of lithium iron phosphate batteries 6 in the intervals of the frame. Remove the top plate 10, which drives the connecting buckle 9 to move and lock the connecting buckle 9 inside the socket 8, connecting the top plate 10 to the base 7. This fixes the lithium iron phosphate batteries 6 between the top plate 10 and the base 7. Finally, connect the connecting piece 5... The terminals of the lithium iron phosphate batteries 6 are connected sequentially to form a series connection between multiple lithium iron phosphate batteries 6. At the same time, the heat dissipation copper plate 3 is inserted from the outside of the sealing shell 1 into the inside of the sealing shell 1 and connected to the heat dissipation fins 4. The heat dissipation copper plate 3 is connected to the sealing shell 1 by sealant. After applying sealant to the edge of the shell cover 2, the shell cover 2 is placed on the sealing shell 1 to complete the seal and form a sealed environment inside, so as to prevent water ingress and damage when the battery pack is working in groundwater. The lithium iron phosphate batteries 6 generate heat when working. This heat is transferred to the surface of the heat dissipation copper plate 3 through the heat conduction of the spacer plate 12 and the heat dissipation fins 4. Since the surface of the heat dissipation copper plate 3 is provided with multiple sets of protrusions 17, the contact area between the heat dissipation copper plate 3 and the groundwater can be increased to transfer the internal heat to the groundwater, thereby conducting heat to cool down the lithium iron phosphate batteries 6 and ensuring the normal operation of the batteries.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
