[0002] With the continuous development of society, engineering vehicles have also developed rapidly. Engineering vehicles are mainly used in building construction. Among them, the water tank radiator is the most important component of the engineering vehicle. During the operation of the engineering vehicle, the water tank radiator is used to cool some components of the engineering vehicle.

[0004] The above-disclosed radiator hot air backflow prevention structure guides the hot air downward along the inclined surface through the guide plate at the air outlet. Although it can avoid the hot air flow gathering above the radiator and prevent the hot air backflow, we still found that the structure still has certain shortcomings during actual use. For example, the gap between the inclined guide plates is used for heat dissipation, but when the heat dissipation and exhaust are stopped, the residual temperature of the radiator will attract heat-loving flying insects, especially in summer. These flying insects enter the radiator to lay eggs and nests, or discharge liquid covering the heat sink or water pipes in the radiator, which will reduce the service life of the radiator and the heat dissipation effect.

[0021] The mounting mechanism 8 includes a groove 801, which is symmetrically arranged at the upper end of the assembly frame 6. A moving block 802 is slidably connected to the inner side of the groove 801. A spring 805 is fixedly installed on the opposite side of the moving block 802 and the groove 801. A first clamping block 803 is fixedly installed on the side of the moving block 802 away from the spring 805. The clamping end of the first clamping block 803 movably penetrates the groove wall of the groove 801 and is clamped with the clamping seat 12. A pull handle 804 is fixedly connected to the upper end of the moving block 802. When the insect-blocking net 10 needs to be maintained, it is only necessary to use the pull handle 804 to simultaneously pull the moving blocks 802 to slide close to each other, and the moving blocks 802 The spring 805 is compressed while sliding in the groove 801. When the first block 803 connected to the shift block 802 is separated from the holder 12, the pull handle 804 is directly used to lift it up, so that the assembly frame 6 can be conveniently and directly removed from the installation frame 5. During installation, the assembly frame 6 is directly inserted along the installation frame 5. During the insertion process, the inclined surface of the block on the assembly frame 6 is squeezed by the holder 12, so that the shift block 802 connected to the block slides in the groove 801 to compress the spring 805. When the position of the block insertion end and the slot 13 of the holder 12 corresponds, the spring 805 is reset to push the block into the holder 12 to be fixed.

[0022] refer to Figure 2The shape of the mounting frame 5 is U-shaped, and a slot 18 is provided at the upper end of the mounting frame 5. The lower end of the assembly frame 6 is plugged into the mounting frame 5 through the slot 18. A card slot 13 is provided on the opposite side of the card holder 12.

A guide rod 14 is symmetrically fixedly installed on the inner side of the groove 801. The moving block 802 is slidably connected to the outer side of the guide rod 14. One end of the guide rod 14 passes through the middle of the spring 805. The moving block 802 slides in the sliding groove 15 of the groove 801 to improve the stability of the moving block 802. The moving block 802 slides on the guide rod 14 to further ensure the sliding stability of the moving block 802. At the same time, the deformation stability of the spring 805 can be ensured by passing through the spring 805.

[0024] refer to Figure 4 The inner side of the assembly groove 16 is fixedly connected with a second clamping block 17, and the assembly groove 16 is clamped with the plastic soft frame 9 through the second clamping block 17. The outer side of the plastic soft frame 9 is symmetrically provided with a notch 11, and the notch of the notch 11 faces the inner wall side of the assembly groove 16. Through the second clamping block 17 on the inner side of the assembly groove 16, the plastic soft frame with the insect-blocking net 10 can be conveniently inserted into the assembly groove 16 step by step, and the notch 11 on the plastic soft frame can be buckled along the notch 11 when disassembling, so as to facilitate the quick removal and maintenance of the insect-blocking net 10 from the assembly groove 16 of the assembly frame 6; the slot position at the horizontal edge of the assembly groove 16 Four second blocks 17 are symmetrically installed, and the notch 11 of the plastic soft frame is between the second blocks 17 in the horizontal phase, and three second blocks 17 are symmetrically installed at the vertical edge slots of the assembly slot 16; although the insect repellent net 10 can block flying insects from entering the radiator body 1, they may be on the side of the insect repellent net 10 close to the wind guide plate 7. Although these blocked flying insects can be blown away by the wind direction, if the vehicle is out of use for too long, stubborn flying insects may produce mucus to block the mesh holes, which will also reduce the ventilation effect of the insect repellent net 10, so regular maintenance of it is also necessary.

[0025] Principle and advantages of use: During use, water is introduced into the upper water tank 2 through an external pipe, and the upper water tank 2 is discharged into the lower water tank 3 through a heat dissipation pipe, and the heat is dissipated through the external heat sink. At the same time, the fan 4 runs through the cooling airflow to quickly carry the heat on the heat sink, and the hot air flows out obliquely downward through the gap of the air guide plate 7 at the assembly frame 6. When the radiator body 1 stops running, the plastic soft frame 9 is clamped at the assembly groove 16 on the back of the assembly frame 6, and the insect-blocking net 10 on the plastic soft frame 9 can effectively prevent heat-loving flying insects from entering the radiator body 1;

[0026] When the insect repellent net 10 needs to be maintained, it is only necessary to use the pull handle 804 to pull the moving block 802 to slide close to each other, and the moving block 802 slides in the groove 801 and compresses the spring 805. When the first clamping block 803 connected to the moving block 802 is separated from the clamping seat 12, the pull handle 804 is directly lifted up, and the assembly frame 6 can be conveniently and directly disassembled and removed from the installation frame 5. When the assembly frame 6 is taken out, it is taken out from the assembly groove 16 along the notch 11 on the plastic soft frame 9 to disassemble the insect repellent net 10 at the plastic soft frame 9. During installation, the assembly frame 6 is directly inserted along the installation frame 5. During the insertion process, the inclined surface of the clamping block on the assembly frame 6 is squeezed by the clamping seat 12, so that the moving block 802 connected to the clamping block slides in the groove 801 and compresses the spring 805. When the clamping end of the clamping block corresponds to the position of the clamping slot 13 of the clamping seat 12, the spring 805 is reset and pushes the clamping block to be clamped into the clamping seat 12 to be fixed.
