Description

Technical Field

[0001] This application relates to the field of road maintenance machinery technology, specifically to a heat dissipation device for road maintenance machinery and the road maintenance machinery itself. Background Technology

[0002] Large road maintenance machinery primarily uses internal combustion engines. During high-speed operation, components such as the engine, hydraulic transmission, and braking system generate significant heat. Failure to dissipate this heat in time can lead to engine overheating, increased fuel consumption, shortened lifespan, and reduced power, thus affecting normal engine operation. Excessive engine temperature can also cause traffic accidents and fires. The radiator, as a critical cooling system, is essential for normal engine operation and even driving safety. Radiators on large road maintenance machinery typically use electric motors as their power source. However, if the motor fails, an emergency cooling device is needed to ensure proper cooling and maintain the normal operation and driving safety of the machinery. Current emergency cooling devices often rely on independent power supplies to drive cooling fans or complex water-cooling systems, such as… Figure 1 As shown, 01 is a grille and 02 is a radiator. These devices have problems such as high cost, complex structure and need for additional energy supply. Summary of the Invention

[0035] This invention discloses a heat dissipation device and a road maintenance machine for road maintenance machinery, in order to solve the problems of existing emergency heat dissipation devices that rely on independent power supply, have high cost and complex structure.

[0036] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0037] Please see Figure 2-5 , Figure 2 This is a schematic diagram of the structure of a heat dissipation device for road maintenance machinery provided in an embodiment of this application; Figure 3 This is a schematic diagram of the structure of the heat dissipation device frame 1 provided in the embodiments of this application; Figure 4 This is a schematic diagram of the structure of the louvered grille assembly 2 provided in the embodiments of this application; Figure 5 This is a schematic diagram of the structure of the louvered grille assembly 2 provided in the embodiment of this application when it is in the open state.

[0038] In one specific embodiment, the present application provides a heat dissipation device for road maintenance machinery, comprising:

[0039] The heat dissipation device frame 1 is used to be installed along the longitudinal direction of the road maintenance machinery and equipment. A grille installation position is provided on each side of the longitudinal center line of the heat dissipation device frame 1, and any grille installation position is set outward and downward from the longitudinal center line.

[0040] Two louvered grille assemblies 2 are located in two grille mounting positions, and each louvered grille assembly 2 includes a number of angle-adjustable blades.

[0041] The heat dissipation device frame 1 extends longitudinally along the road maintenance machinery and equipment. At the same time, the longitudinal direction of the heat dissipation device frame 1 is the same as the longitudinal direction of the road maintenance machinery and equipment. A grille mounting position is provided on both sides of the longitudinal center line of the heat dissipation device frame 1. Each grille mounting position is set outward and downward from the longitudinal center line. It can be understood that with the location of the longitudinal center line as the center, the direction away from the longitudinal center line is the outside, and the grille mounting position is set outward and downward from the longitudinal center line, thereby providing more heat dissipation area and improving heat dissipation effect.

[0042] The louvered grille assemblies 2 are respectively installed in their corresponding grille mounting positions. Each louvered grille assembly 2 includes several angle-adjustable blades, so that after the radiator 3 dissipates heat, it can be discharged through the louvered grille assemblies 2 on both sides, ensuring smooth airflow. At the same time, when the road maintenance machinery has components that are not resistant to high temperatures, the blades can be changed to adjust the airflow direction, preventing the exhaust air from blowing directly onto the relevant components. The louvered grille assemblies 2 are preferably detachably fixed to the grille mounting positions, such as by using screws or other threaded fasteners, which facilitates regular maintenance and inspection of the radiator. The blade angle of the louvered grille assembly 2 is adjustable, so that the blades can be opened at the required angle as needed to ensure smooth airflow.

[0043] The heat dissipation device and road maintenance machinery provided in this application have the following technical advantages compared to the prior art:

[0044] In this application, the heat dissipation device is arranged longitudinally along the road maintenance machinery. Grille mounting positions are provided on both sides of the longitudinal centerline of the heat dissipation device frame 1, and louvered grille assemblies 2 are respectively installed at the grille mounting positions. Each louvered grille assembly 2 has several angle-adjustable blades. Based on the longitudinal arrangement of the heat dissipation device, it utilizes the passive airflow from high-speed traffic to achieve heat dissipation for the emergency devices on the road maintenance machinery. Its structure is simple, low-cost, and requires no additional high-power energy supply. It effectively utilizes the airflow during high-speed traffic for heat dissipation and can be widely applied to various large-scale road maintenance machinery requiring emergency heat dissipation, improving the reliability and stability of the equipment under special working conditions. Simultaneously, for road maintenance machinery with components that are not resistant to high temperatures, the angle-adjustable blades of the louvered grille assembly 2 can adjust the airflow direction, preventing exhaust air from directly blowing onto the relevant components. Furthermore, when the radiator 3 on the road maintenance machinery malfunctions and cannot be used, the windward grille blades can be opened and the opposing grille blades closed according to the traffic direction, using the heat dissipation device frame 1 to guide the high-speed traffic airflow into the radiator 3 for passive cooling.

[0045] In one embodiment, the heat dissipation device frame 1 includes two oppositely arranged air guide side plates 11, which extend longitudinally along the road maintenance machinery. Connectors 12 are provided at the middle and both ends of the air guide side plates 11, and the connectors 12 and the air guide side plates 11 form a grille mounting position.

[0046] Two air guide side plates 11 are arranged opposite each other along the transverse direction of the road maintenance machinery, while each air guide side plate 11 extends longitudinally along the road maintenance machinery to guide airflow according to the driving direction of the road maintenance machinery. The two air guide side plates 11 are relatively fixed and can be fixedly connected by connectors 12. Specifically, connectors 12 are provided in the middle and at both ends of the air guide side plates 11, and the two air guide side plates 11 are connected in the middle and at both longitudinal ends by the connectors 12. Specifically, there are three connectors 12, which are respectively arranged in the middle and at both ends of the air guide side plates 11 to fix the two air guide side plates 11. The connectors 12 are preferably fixed to the air guide side plates 11 by welding or threaded connection. The connectors 12 can be set as connecting rods or connecting pipes, specifically rectangular tubes. It can be understood that the two oppositely arranged air guide side plates 11 and the three connectors 12 located in the middle and at both ends form two grille mounting positions for installing the louver grille assembly 2.

[0047] Therefore, the air guide side plate 11 is set to quickly guide the airflow, form an efficient heat dissipation channel, help the air flow quickly through the radiator, accelerate the heat dissipation process, and ensure the stability of vehicle operation.

[0048] The air guide side plate 11 can be configured as a rectangular plate, an arc plate, or other plate structure. Preferably, the air guide side plate 11 is a triangular air guide side plate 11, specifically an isosceles triangle structure, to facilitate the installation of the connector 12 and the grille mounting position, so that the grille mounting position forms a structure that is obliquely downward from the longitudinal center line. Specifically, a connector 12 is provided at the top of the side of the two triangular air guide side plates 11, and a connector 12 is provided at the bottom of the side of the two triangular air guide side plates 11, thereby forming two grille mounting positions respectively.

[0049] In this embodiment, any one hundred-blade grille assembly 2 includes:

[0050] Mounting bracket 21;

[0051] At least one louver 22, the first end of any 100 louvers 22 is rotatably connected to the mounting bracket 21, and the second end is a free end;

[0052] A connecting rod is connected to the louver 22, and the connection point between the connecting rod and the louver 22 is spaced from the first end of the louver 22.

[0053] The central shaft connecting rod 24 is rotatably connected to one end of the connecting rod principle louver 22;

[0054] The power component 23 is fixed on the mounting bracket 21, and the drive end of the power component 23 is rotatably connected to the central shaft connecting rod 24.

[0055] Mounting bracket 21 is a rectangular mounting bracket. A reinforcing plate is located in the middle of the mounting bracket 21, and a power component 23 is mounted on the reinforcing plate. The power component 23 is rotatably connected to the reinforcing plate. A connecting rod is connected to louvers 22, and the connection point between the connecting rod and the louver 22 is spaced from the first end of the louver 22. A central shaft connecting rod 24 is rotatably connected to the end of the connecting rod away from the louver 22. The power component 23 is rotatably connected to the central shaft connecting rod 24, which extends longitudinally. The driving end of the power component 23 is connected to the middle of the central shaft connecting rod 24 along its length. The power component 23 drives the central shaft connecting rod 24 to move longitudinally, thereby driving the connecting rod to drive the louver 22 to rotate around the mounting bracket 21, thus achieving angle adjustment of the louver 22. Specifically, the connecting rod has an arc-shaped structure.

[0056] The power component 23 is preferably a cylinder or a hydraulic cylinder. The cylinder includes a cylinder body and a piston rod. One end of the cylinder body is connected to the top of the reinforcing plate. The cylinder body has an inner cavity. One end of the piston rod is movably connected to the inner cavity, and the other end passes through the cylinder body and extends outward. The piston rod can extend or retract relative to the cylinder body to form the driving end of the cylinder. The end of the piston rod located outside the cylinder body is connected to the central shaft connecting rod 24. When the piston rod is in the retracted state, the louvers 22 are in the closed state.

[0057] Furthermore, the edges of the louvers 22 are provided with sealing gaskets. When the louvers 22 are in the closed state, the sealing gaskets press against adjacent louvers 22. Simultaneously, sealing gaskets are provided on the mounting bracket 21 so that when the louvers 22 are closed, the louvers 22 at the ends can press against the sealing gaskets of the mounting bracket 21, improving sealing performance. Specifically, the louvers 22 are configured as multiple pieces, equidistantly arranged, so that when the louvers 22 are closed, they cover the grille mounting position. The sealing gaskets ensure that liquid does not leak through the louver grille assembly 2 when the louvers are closed.

[0058] In one specific embodiment, the heat dissipation device for road maintenance machinery provided in this application opens the left and right movable louver grilles when the radiator fan is working normally, and the air outlet after the radiator dissipates heat is directly discharged through the left and right movable louver grilles; when the radiator fan cannot work, the front grille can be opened and the opposite grille closed according to the driving direction and the equipment's heat dissipation needs, thereby adjusting the size and angle of the air inlet, optimizing the air intake volume and air intake direction, and using the air guide shroud to guide the driving air into the radiator core for heat dissipation and cooling of the heat-generating components, so as to solve the problems of high cost, complex structure and additional energy required by existing emergency heat dissipation devices.

[0059] The louver 22 can be completely closed when the vehicle is stopped, which can effectively prevent rain and snow from entering the engine compartment, while also protecting against external debris such as leaves and branches, keeping the inside of the radiator clean and extending its service life.

[0060] This application also provides a road maintenance machinery equipment, which includes a heat dissipation device for road maintenance machinery equipment as described in any of the above embodiments. The heat dissipation device frame 1 is fixed on the roof of the road maintenance machinery equipment and is located above the radiator 3 of the road maintenance machinery equipment.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of this application.
