By setting the protective cover 201, the fuel cell is directly wrapped, which plays a basic protective and heat insulation role. By setting the spiral cavity 202, gas can be circulated. The airflow can block heat conduction and improve the heat insulation effect. By setting the connecting pipe 203, the air pump 204 is connected to the spiral cavity 202, providing a channel for gas inflow. By setting the air pump 204, gas is injected into the spiral cavity 202, driving the airflow circulation. By setting the connecting pipe 205, the spiral cavity 202 is connected to the exhaust valve 206, providing a channel for gas outflow. By setting the exhaust valve 206, the gas discharge in the spiral cavity 202 is controlled, and the air pressure and airflow circulation speed in the cavity are adjusted.

[0020] Specifically, such as Figure 3 As shown, the base assembly 1 includes a base plate 101. Two adjustment slots 102 are provided on the top of the base plate 101. Threaded rods 103 are rotatably connected to the inner walls of the two adjustment slots 102. Adjustment blocks 104 are threadedly connected to the surfaces of the two threaded rods 103. Limiting blocks 105 that cooperate with the protective cover 201 are fixedly connected to the opposite side of the two adjustment blocks 104.

[0021] Specifically, such as Figure 3 As shown, a sealing groove 106 is provided on the top of the base plate 101, and a sealing block 107 is snapped into the inner wall of the sealing groove 106. The sealing block 107 is fixedly connected to the bottom of the protective cover 201.

[0022] Specifically, such as Figure 3 As shown, adjusting nuts 108 are fixedly connected to opposite sides of the two threaded rods 103, and both adjusting nuts 108 are made of stainless steel.

[0023] In this embodiment: A base plate 101 is set as the installation foundation for the entire heat insulation cover, supporting all components above it. An adjustment groove 102 is set to provide rotational installation space for the threaded rod 103 and limit the movement trajectory of the adjustment block 104. The threaded rod 103 is set to rotate and drive the adjustment block 104 to move, thereby adjusting the position of the limit block 105. The adjustment block 104, in conjunction with the threaded rod 103, drives the limit block 105 to move closer to or away from the protective cover 201. The limit block 105 is set to clamp and fix the protective cover 201 to prevent it from shifting. A sealing groove 106 and a sealing block 107 are set, with the inner walls of the sealing block 107 and the sealing groove 106 spliced ​​together to enhance the sealing effect between the protective cover 201 and the base plate 101. An adjustment nut 108 is set to facilitate the operator to rotate the threaded rod 103. The stainless steel material improves corrosion resistance and durability.

[0024] Specifically, such as Figure 4 As shown, a corrosion-resistant cover 3 is fitted on the surface of the protective cover 201, and a protective sleeve 4 is fixedly connected to the inner wall of the protective cover 201.

[0025] Specifically, such as Figure 5 As shown, the protective cover 201 has adjustment handles 5 fixedly connected to both the left and right sides, and anti-slip plates 6 are fixedly connected to the surfaces of both adjustment handles 5.

[0026] In this embodiment: by setting a corrosion-resistant cover 3, which is fitted onto the surface of the protective cover 201, the protective cover 201 is protected from corrosive environments such as marine salt spray. By setting a protective sleeve 4, which is fixed to the inner wall of the protective cover 201, the heat insulation effect is further enhanced, while avoiding direct friction between the inner wall of the protective cover 201 and the fuel cell. By setting an adjustment handle 5, the protective cover 201 is easily moved, installed, or disassembled by the operator, improving the ease of operation. By setting an anti-slip plate 6, which is fixed to the surface of the adjustment handle 5, the friction between the hand and the handle is increased, preventing slippage during operation.

[0027] Specifically, such as Figure 1 As shown, a protective shell 7 is fixedly connected to the top of the protective cover 201. The protective shell 7 is made of stainless steel.

[0028] Specifically, such as Figure 1 As shown, a frame 8 is fixedly connected to the inner wall of the protective shell 7, and a protective net 9 is fixedly connected inside the frame 8.

[0029] In this embodiment: by setting a protective shell 7, which is fixed to the top of the protective cover 201, the stainless steel material increases the strength and protects the top of the protective cover 201 from impact damage. By setting a frame 8, which is installed on the inner wall of the protective shell 7, a supporting and fixing structure is provided for the protective net 9. By setting a protective net 9, which is fixed inside the frame 8, it blocks debris or external forces from impacting the protective shell 7, while not affecting the gas flow.

[0030] Working principle: Using the base plate 101 as the installation foundation, rotating the adjusting nut 108 drives the threaded rod 103 to rotate, causing the adjusting block 104 to drive the limiting block 105 to clamp the protective cover 201 and complete the fixation. At the same time, the sealing block 107 at the bottom of the protective cover 201 engages with the sealing groove 106 of the base plate 101 to enhance the sealing performance. After starting the air pump 204, the gas enters the spiral cavity 202 on the inner wall of the protective cover 201 through the connecting pipe 203, forming a circulating airflow to block heat conduction. Then, the gas is discharged through the connecting pipe 205 by the exhaust valve 206, adjusting the air pressure and airflow speed in the cavity to ensure the heat insulation effect. The corrosion-resistant cover 3 on the surface of the protective cover 201 resists marine salt spray corrosion, the inner wall protective sleeve 4 strengthens heat insulation and avoids friction with the battery, the top stainless steel protective shell 7 works with the frame 8 and protective net 9 to block external impacts, and the adjusting handles 5 on both sides facilitate the overall installation and disassembly, together achieving multi-dimensional protection and efficient heat insulation for the fuel cell.

[0031] The above are merely preferred embodiments of the present utility model and are 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.
