Description

Technical Field

[0001] This utility model relates to the field of explosion-proof safety protection equipment technology, and in particular to an explosion-proof safety protection device for chemical battery energy storage. Background Technology

[0002] A chemical battery is a device that converts chemical energy into electrical energy. Its main components include an electrolyte solution and two electrodes immersed in the solution, one positive and one negative. In use, a wire is connected to the two electrodes, allowing current to flow (discharge), thus generating electrical energy. After discharging to a certain extent, the electrical energy decreases. Some batteries can be recharged and reused; these are called storage batteries, such as lead-acid batteries and nickel-iron batteries. Others cannot be recharged and are called primary batteries, such as dry cell batteries, Denier batteries, and fuel cells.

[0003] For example, the explosion-proof safety protection device for chemical battery energy storage disclosed in Chinese Patent No. CN217334271U works on the principle that "through the cooperation of the support drawer, fastening limiting component and explosion-proof box, the chemical battery can be fixed and stored in the explosion-proof box, thereby avoiding damage to the chemical battery caused by external impacts, which may lead to spontaneous combustion and explosion." However, in actual use, the hollow pressure plate and hollow rubber pad in the fastening limiting component of this patent fasten the battery. Because the battery generates a certain amount of heat during energy storage, the hollow pressure plate and hollow rubber pad are close to the two ends of the battery, which makes it impossible for the heat at the two ends of the battery to be dissipated in time. Although the hollow pressure plate and hollow rubber pad have a hollow design, it is a passive heat dissipation, so some heat still cannot be dissipated in time, which will affect the performance of the chemical battery.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the following provides a more detailed description of the utility model. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the utility model.

[0028] Please see Figures 1-5 This utility model provides a technical solution: an explosion-proof safety protection device for chemical battery energy storage, including a protective box 1, a fan 3 fixedly installed at the bottom of the protective box 1, the exhaust end of the fan 3 communicating with the inner cavity of the protective box 1; a horizontal support frame 2 fixedly installed in the inner cavity of the protective box 1, the bottom end face and the top end face of the support frame 2 respectively having an air inlet and an air outlet; multiple cooling pipes 6 are installed side by side inside the support frame 2; a liquid distribution channel 5 is provided on the side of the support frame 2, which is connected to the water inlet of each of the cooling pipes 6, and the liquid distribution channel 5 is connected to a cooling water inlet interface;

[0029] The inner cavity of the protective housing 1, located above the supporting frame 2, is provided with a fixed heat dissipation mechanism 7 for clamping and fixing the chemical battery.

[0030] An external water pump draws cooling water into the distribution channel 5, which then flows into each cooling pipe 6, cooling the air inside the support frame 2. The fan 3 then draws external air into the protective housing 1 and the support frame 2. After being cooled by the cooling pipes 6 inside the support frame 2, the air enters the fixed heat dissipation mechanism 7, dissipating heat at the points in contact with the battery. This ensures timely heat dissipation from the battery, guaranteeing its performance.

[0031] Specifically, the fixed heat dissipation mechanism 7 includes a lifting plate 71, a clamping and fixing frame 73, an air supply pipe 75, a lifting plate drive mechanism, and a clamping and fixing frame drive mechanism; the fixed heat dissipation mechanism 7 is engaged with the inner wall of the inner cavity of the protective box 1.

[0032] A horizontally oriented lifting plate 71 is disposed above the support frame 2. The ends of the lifting plates 71 that are far apart from each other are engaged with the inner wall of the inner cavity of the protective housing 1. The lifting plates 71 move up and down under the drive of the lifting plate driving mechanism. Two clamping and fixing frames 73 are disposed on the top surface of the lifting plate 71. The lower ends of the clamping and fixing frames 73 are engaged with the outer wall of the lifting plate 71. The two clamping and fixing frames 73 move towards or away from each other under the drive of the clamping and fixing frame driving mechanism. A chemical battery is installed between the two clamping and fixing frames 73. The bottom of each clamping and fixing frame 73 is connected to the inner cavity of the support frame 2 through a gas supply pipe 75. Heat dissipation holes 76 are provided on the sides of the two clamping and fixing frames 73 that are close to each other. Protective pads are installed on the sides of the two clamping and fixing frames 73 that are close to each other.

[0033] like Figure 4 As shown, the battery is secured by the two clamping and fixing frames 73 approaching each other. Then, the fan 3 is activated to allow air to enter the support frame 2, which is then cooled by the cooling pipe 6 inside the support frame 2. The cooled air then enters the air supply pipe 75 and then enters the clamping and fixing frame 73, dissipating heat at the contact point between the clamping and fixing frame 73 and the battery. This ensures that the battery's heat is dissipated in a timely manner, thus guaranteeing the battery's performance.

[0034] As a specific implementation structure, the lifting plate driving mechanism is a first screw 72; the first screw 72 is vertically arranged, and the upper and lower ends of the first screw 72 are rotatably connected to the inner wall of the inner cavity of the protective box 1, and the outer wall of the first screw 72 is threadedly connected to the inner wall of the lifting plate 71, and a knob for easy rotation by personnel is installed on the upper end of the first screw 72.

[0035] like Figure 4 As shown, the first screw 72 is rotated by rotating the knob installed on the upper end of the first screw 72. The rotation of the first screw 72 causes the lifting plate 71 to move up and down, so that the battery installed on the upper end of the lifting plate 71 can be discharged into the protective box 1, so that personnel can easily take out the battery.

[0036] As a specific implementation structure, the clamping and fixing frame driving mechanism is a second screw 74; the second screw 74 is horizontally arranged, the outer walls of the left and right ends of the second screw 74 are rotatably connected to the inner wall of the lifting plate 71, and the outer wall of the second screw 74 is threadedly connected to the inner wall of the lower end of the two clamping and fixing frames 73, and a knob with a limit position is fixedly connected to one end of the second screw 74 that is far away from each other.

[0037] By rotating the knob with a limit switch, the second screw 74 is driven to rotate, causing the clamping and fixing frame 73 to move closer together and fix the battery. Then, the second screw 74 is limited by the knob with a limit switch to prevent the second screw 74 from reversing, thereby indirectly ensuring the stability of the clamping and fixing frame 73 for the battery.

[0038] The top of the protective housing 1 is fixedly connected to an air outlet pipe 4, and a dust cover is installed on the outer wall of the air outlet pipe 4. A removable filter screen is installed at the bottom of the protective housing 1.

[0039] like Figure 5 As shown, the exhaust duct 4 allows for the convenient discharge of cooled air. A dust cover is installed at the upper end of the exhaust duct 4 to prevent dust from entering the interior of the protective housing 1. A removable filter is installed at the lower end of the protective housing 1 to filter impurities in the air and prevent dust from entering the interior of the protective housing 1. The filter is removable, allowing personnel to remove and clean it.

[0040] The explosion-proof safety protection device for chemical battery energy storage provided by this utility model has the following advantages:

[0041] An external water pump draws cooling water into the distribution channel, which then flows into the cooling pipes to cool the air inside the support frame. A fan then draws external air into the protective enclosure and support frame, where it is cooled by the cooling pipes and enters the fixed heat dissipation mechanism. This heat dissipates heat from the points in contact with the battery, ensuring timely heat dissipation and maintaining battery performance.

[0042] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
