[0029] Such as Figure 1-7As shown in the figure, a heat dissipation structure for the carriage of an engineering vehicle according to the present utility model includes a carriage 1 fixed on the engineering vehicle. On one side inside the carriage 1, a support frame 2 for supporting two sewage pumps is slidably arranged. On the other side inside the carriage 1, a hydraulic power device 3 for driving the above two sewage pumps to operate is arranged. An opening is communicatively arranged on the air inlet surface of the hydraulic power device 3 and outside the carriage 1.

[0030] A filter assembly 4 is detachably arranged in the opening and is used to filter out dust in the air and enter the inside of the hydraulic power device 3. With such a design, through an opening machined on the outside of the carriage 1 and corresponding to the air inlet surface of the hydraulic power device 3, and a filter assembly 4 detachably assembled in the opening, during the drainage operation when the vehicle is parked, the filter assembly 4 can be used to adjust the amount of air entering the inside of the hydraulic power device 3, and the filter assembly 4 can also be used to filter out dust in the air and enter the inside of the hydraulic power device 3, preventing dust from entering and affecting the use performance.

[0031] In an embodiment, the filter assembly 4 includes a mesh plate one 41 arranged in the opening, a mesh plate two 42 arranged on the mesh plate one 41. A guide rod 43 is fixedly arranged at the upper end of the mesh plate two 42. An activity groove is arranged at the top of the mesh plate one 41 outside the guide rod 43. With such a design, by using the way that the guide rod 43 moves left and right in the activity groove on the rear vertical surface of the mesh plate one 41 to control the position of the mesh plate two 42, the effect of adjusting the air intake amount by the superposition size of the mesh holes on the mesh plate one 41 and the mesh plate two 42 can be achieved.

[0032] Preferably, a positioning plate 44 for cooperating with the end of the guide rod 43 is arranged on the end face of the activity groove. With such a design, on the one hand, the strip groove machined on the end face of the positioning plate 44 can support the lateral movement of the positioning plate 44 at the end of the guide rod 43, and on the other hand, it can support the rotation of the positioning plate 44 at the end of the guide rod 43. After the guide rod 43 is operated to drive the mesh plate two 42 to move to a specified position, after the sequential lateral movement and rotation operations of the positioning plate 44, the positioning plate 44 can be placed on the open end face of the activity groove to achieve the limiting effect and prevent movement.

[0033] It should be noted that when the mesh holes on the mesh plate one 41 and the mesh plate two 42 are completely misaligned and superimposed, a closed shielding plate structure will be formed, which can effectively block external dust from entering during the driving of the engineering vehicle or when the hydraulic power device 3 is not in use.

[0034] In an embodiment, assembly grooves 45 are symmetrically arranged at the lower ends on both sides of the mesh plate one 41;

[0035] The assembly block 5 is fitted and arranged in the assembly groove 45 for the convenient installation and removal of the filter assembly 4. With this design, through the assembly grooves 45 machined by turning at the lower ends on both sides of the first mesh plate 41, the filter assembly 4 can be fixed at the opening in cooperation with the assembly block 5, realizing the function of filtering dust in the air on the filter assembly 4.

[0036] It should be noted that the assembly groove 45 is in a fan-shaped groove structure.

[0037] In one embodiment, a support column 51 fixed to the inner side of the opening is rotatably arranged at one end of the assembly block 5. With this design, through the support column 51 welded to the inner side of the opening and the assembly block 5 rotatably sleeved on the end face of the support column 51, when the assembly blocks 5 on both sides rotate towards each other, the filter assembly 4 will be limited and assembled, and when the assembly blocks 5 on both sides rotate outwards synchronously, the filter assembly 4 will be separated for removal, enabling the regular cleaning of the dust accumulated on the filter assembly 4.

[0038] In one embodiment, a housing 6 for protecting the hydraulic power device 3 is arranged outside the hydraulic power device 3 and on one side inside the carriage 1, and heat dissipation fins 61 attached to the heat generating surface of the hydraulic power device 3 are arranged on the housing 6. With this design, through the housing 6 for protecting the hydraulic power device 3 welded on one side inside the carriage 1 and the heat dissipation fins 61 integrally formed on the housing 6, the surface area of contact between the air and the heat dissipation fins 61 is increased, improving the heat dissipation efficiency.

[0039] In one embodiment, two ventilation pipes are symmetrically arranged on the top surface of the housing 6. With this design, through the two symmetric ventilation pipes bolted to the top surface of the housing 6 and communicating with the heat generated by the hydraulic power device 3, an air flow path at the hydraulic power device 3 is formed to ensure that the heat can be discharged smoothly.

[0040] In one embodiment, a heat dissipation device 7 is arranged on one side of the carriage 1, and a cover plate 8 connected by a hydraulic rod is arranged on the carriage 1 at the air outlet of the heat dissipation device 7. With this design, through the heat dissipation device 7 fixed by screws in the groove machined on one side of the carriage 1 and the cover plate 8 connected by a hydraulic rod in the groove opened on the carriage 1 outside the heat dissipation device 7, during the parking and drainage operation, the cover plate 8 can be opened and the heat dissipation device 7 can be started to form a negative pressure air flow outwards, which can take away the heat generated during the operation of the hydraulic power device 3.

[0041] It should be noted that the heat dissipation device 7 includes but is not limited to two fan blades and a grille for protecting the two fan blade devices.

[0042] In one embodiment, a ventilation opening 9 is provided on the other side of the carriage 1 opposite to the heat dissipation device 7, and a second cover plate 10 connected by a hydraulic rod is provided at the ventilation opening 9. With such a design, by machining the ventilation opening 9 on the other side of the carriage 1 opposite to the heat dissipation device 7 and using the second cover plate 10 connected by a hydraulic rod at the ventilation opening 9, the second cover plate 10 can be opened during the drainage operation, and in cooperation with the use of the heat dissipation device 7, the air flow in the carriage 1 can be accelerated, the hot air can be discharged, and the heat dissipation efficiency can be further improved.

[0043] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above-described exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
