DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] See also Figures 1 to 3 The utility model provides a technical solution: a van-type maintenance vehicle with a power generation device, including a body 1, which can be a four-wheeled vehicle, and a closed compartment 2 is arranged at the rear of the body 1, that is, the maintenance vehicle can be a van, and a tailgate 3 is arranged at the rear of the closed compartment 2 and a side door 4 is arranged on one side, and the closed compartment 2 is used to load maintenance tools.

[0022] In this technical solution, a machine base 5 is arranged near the front end in the closed compartment 2, and a diesel generator set 6 is arranged on the machine base 5. The closed compartment 2 can protect the diesel generator set 6, such as from dust and rain, and can also reduce the power generation noise and reduce noise pollution.

[0023] Furthermore, a vent 7 located above the diesel generator set 6 is provided on the top of the closed compartment 2. The function of the vent 7 is to discharge the heat generated by the operation of the diesel generator set 6 to the outside. The top of the closed compartment 2 is connected to a cover 8 that slides up and down. The cover 8 can control the opening and closing of the vent 7 when it moves up and down. A cooling fan 9 opposite to the vent 7 is hung below the cover 8. When the vent 7 is opened, the cooling fan 9 can fill the vent 7. When the cooling fan 9 is started, it can extract the heat generated by the diesel generator set 6 to the outside. The side door 4 or the tailgate 3 can be opened to facilitate the entry of fresh air into the closed compartment 2. Therefore, it has the advantages of ventilation and heat dissipation, and the noise will be transmitted upward with the airflow, greatly reducing the noise generated by power generation.

[0024] Specifically, the bottom of the cover 8 is fixedly connected with a slot frame 81 that penetrates the closed compartment 2, a crossbeam 811 on the slot frame 81 is located in the closed compartment 2 and a positioning ring 8111 is fixedly connected in the middle thereof, and the cooling fan 9 is sleeved in the positioning ring 8111 and is detachably connected, that is, when the slot frame 81 moves up and down, the cooling fan 9 can be driven to move up and down through the positioning ring 8111. The detachable connection feature of the cooling fan 9 has the advantage of convenient maintenance of the cooling fan 9.

[0025] Furthermore, a positioning air hood 91 is provided on the outside of the cooling fan 9 and is gap-mounted on the outside of the positioning ring 8111. A locking bolt 102 is screwed through the outer wall of the positioning ring 8111. One end of the locking bolt 102 is opposite to the outer wall of the positioning air hood 91. When the locking bolt 102 is tightened, the outer wall of the positioning air hood 91 will be squeezed and fixed. When the locking bolt 102 is loosened, the positioning air hood 91 and the positioning ring 8111 can be easily separated.

[0026] In this embodiment, the two vertical poles 82 on the groove frame 81 are slidably connected to the top of the closed compartment 2. In specific implementation, a limit sleeve arranged on the outside of the vertical pole 82 can be welded on the top of the closed compartment 2. The vertical pole 82 and the limit sleeve are slidably matched. The crossbeam 811 and the top of the closed compartment 2 are connected through a lifting control rod 101. The function of the lifting control rod 101 is to control the up and down movement of the groove frame 81. The lifting control rod 101 can be a cylinder or an electric telescopic rod.

[0027] Furthermore, connecting rods 821 are welded on both sides of the vertical rod 82, and a ventilation pipe 103 with a blind top is welded on one end of the connecting rod 821. A guide sleeve 21 is welded through the top of the closed compartment 2 and is sleeved on the outside of the ventilation pipe 103. The guide sleeve 21 and the ventilation pipe 103 are sealed and slidably matched. In specific implementation, a sealing rubber sleeve can be nested in the guide sleeve 21 to achieve the sealed match between the ventilation pipe 103 and the guide sleeve 21. The outer peripheral wall of the ventilation pipe 103 is provided with a ventilation hole 1031 near the top. The function of the ventilation pipe 103 is to introduce the fresh air outside the top of the closed compartment 2 into the closed compartment 2. When the vent 7 is opened, the above ventilation hole 1031 will be located outside the closed compartment 2, and when the vent 7 is closed, the ventilation hole 1031 will be located inside the closed compartment 2. There is no need to open the tailgate 3 and the side door 4 to add fresh air to the closed compartment 2, which is convenient for the maintenance vehicle to move and generate electricity.

[0028] Furthermore, a rain cover 1032 is welded to the top of the ventilation pipe 103 , and the function of the rain cover 1032 is to prevent rainwater from entering the ventilation hole 1031 .

[0029] In this embodiment, a rainproof ring 22 is welded to the outside of the top of the closed compartment 2, and the vent 7 is located inside the rainproof ring 22. The top of the rainproof ring 22 is sleeved with a sealing ring 221 that cooperates with the lower surface wall of the cover 8. That is to say, when the cover 8 moves downward to fit with the sealing ring 221, the cover 8 and the rainproof ring 22 are in a sealed cooperation state, thereby improving the reliability of dust and rain protection.

[0030] Working principle: When power generation is needed for maintenance on rainy days, the groove frame 81 is driven to move upward by the lifting control rod 101. At this time, the cover 8 moves up, the vent 7 is opened, and the cooling fan 9 enters the vent 7. At the same time, the ventilation pipe 103 moves upward, and the ventilation hole 1031 is located outside the closed compartment 2. Then the diesel generator set 6 and the cooling fan 9 are started, and the fresh air from the outside will enter the closed compartment 2 through the ventilation hole 1031, and the hot air in the closed compartment 2 will be discharged outward through the vent 7. Due to the shielding effect of the rain cover 1032 and the cover 8, rainwater is prevented from entering the closed compartment 2.

[0031] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
