[0034] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0035] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0036] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0037] Example 1

[0038] Reference Figure 1 to Figure 4 , which is the first embodiment of the present invention, provides a hydraulic excavator fire protection device, including a main body component 100, including an equipment chassis 101, an inspection window 102 arranged on the equipment chassis 101, a heat dissipation window 103 arranged on the equipment chassis 101, and heat dissipation fins 104 arranged on the heat dissipation window 103; and a fire protection component 200, including a fire protection frame 201 arranged on the heat dissipation window 103, a fire protection cloth 202 arranged on the fire protection frame 201, an installation component 203 arranged on the fire protection frame 201, a cleaning component 204 arranged on the fire protection frame 201, and a discharge component 205 arranged on the cleaning component 204.

[0039] Among them, the equipment chassis 101 is the core part of the hydraulic excavator, which is used to accommodate various equipment systems to ensure effective protection of its internal electronic control unit, hydraulic pump, motor and other key systems. Its internal space layout is reasonable, which is convenient for various system integration and maintenance. In order to prevent the equipment motor from overheating during long-term operation, it is often equipped with special heat dissipation equipment inside, and the setting of the heat dissipation window 103 is to ensure the normal operation of its internal heat dissipation system. There are two heat dissipation windows 103, which are symmetrically arranged on both sides of the equipment chassis 101, so that the gas circulation inside the equipment chassis 101 can be ensured. The heat dissipation fins 104 are installed on the inner side of the heat dissipation window 103 and are made of high-efficiency heat-conducting materials, such as aluminum fins. The heat dissipation efficiency is improved by increasing the surface area to ensure that the temperature of the equipment is controllable when working under high load. The fireproof frame 201 is located inside the heat dissipation window 103, and the fireproof cloth 202 used for installation and fixing is usually made of high-temperature resistant and flame-retardant materials. It is installed close to the internal contour of the heat dissipation window 103 to provide a stable support for the fireproof cloth 202 while ensuring that the heat dissipation efficiency is not affected.

[0040] Furthermore, the fireproof cloth 202 is located inside the heat dissipation window 103. The fireproof cloth 202 is made of a multi-layer composite material. The outer layer is a high-temperature resistant and flame-retardant fabric, and the inner layer contains a high-efficiency filter medium. This can not only prevent large particles of coal powder from passing through, but also reduce the risk of fire spread caused by high temperature. On the one hand, it can filter and isolate coal powder from entering the turbocharger system. On the other hand, the fireproof cloth 202 can reduce the heat dissipation system from blowing coal powder to the vicinity of the turbocharger system, thereby preventing fire from occurring.

[0041] The mounting assembly 203 includes a mounting frame 203a arranged on the heat dissipation window 103, a mounting groove 203b opened on the mounting frame 203a, a mounting slider 203c arranged on the fireproof frame 201, and a reinforcement 203d arranged on the fireproof frame 201; the mounting frame 203a is located at the upper and lower ends of the heat dissipation window 103, the mounting groove 203b is opened on the mounting frame 203a, and the mounting slider 203c and the mounting groove 203b are slidably connected.

[0042] Among them, the mounting frame 203a is located at the upper and lower ends of the heat dissipation window 103, and its cross-section is L-shaped, which is used to cover the upper and lower edges of the heat dissipation window 103 to ensure the stability of the mounting structure. The mounting frame 203a and the heat dissipation window 103 are fixedly connected, and the mounting slide 203b is located on the mounting frame 203a. The mounting slide 203b is a straight-line slide, which cooperates with the mounting slider 203c to position and guide the fireproof frame 201 during installation to ensure that the sliding cooperation between the two is both tight and flexible. The mounting slider 203c is located at the upper and lower ends of the fireproof frame 201, and the mounting slider 203c and the fireproof frame 201 are fixedly connected. The reinforcement 203d can be used to reinforce the fireproof frame 201 after it slides into place, thereby increasing the tightness between the fireproof frame 201 and the mounting frame 203a.

[0043] The reinforcing member 203d includes a reinforcing connecting rod 203d-1 arranged on the heat dissipation window 103, a reinforcing locking buckle 203d-2 arranged on the reinforcing connecting rod 203d-1, and a reinforcing card slot 203d-3 arranged on the fireproof frame 201; the reinforcing connecting rod 203d-1 is located on the left and right sides of the heat dissipation window 103, the reinforcing connecting rod 203d-1 and the heat dissipation window 103 are slidably connected, the reinforcing locking buckle 203d-2 and the reinforcing card slot 203d-3 are adapted to each other, an elastic spring plate 203d-4 is arranged below the reinforcing connecting rod 203d-1, a reinforcing slide groove 203d-5 is opened on the heat dissipation window 103, the elastic spring plate 203d-4 is located in the reinforcing slide groove 203d-5, and an extrusion block 203d-6 is arranged on the upper end of the reinforcing locking buckle 203d-2.

[0044] Among them, the number of reinforcement connecting rods 203d-1 is two and they are symmetrically arranged. The reinforcement connecting rod 203d-1 and the heat dissipation window 103 are slidably connected. The part of the reinforcement connecting rod 203d-1 extending into the heat dissipation window 103 is made of hard material. The upper end of the reinforcement connecting rod 203d-1 is made of elastic metal material. The reinforcement lock buckle 203d-2 is located at the upper end of the reinforcement connecting rod 203d-1. The reinforcement lock buckle 203d-2 and the reinforcement connecting rod 203d-1 are fixedly connected. The reinforcement lock buckle 203d-2 is engaged with both sides of the fireproof frame 201, and a reinforcement card slot 203d-3 corresponding to the reinforcement lock buckle 203d-2 is opened on the fireproof frame 201. The cross-section of the reinforcement slot 203d-3 is a radial triangle, and the diameter of the end close to the fireproof lock buckle is smaller than the end away from the fireproof lock buckle. The elastic spring plate 203d-4 is located in the reinforcement slide groove 203d-5. The elastic spring plate 203d-4 is made of metal material with elasticity and can be restored. It is used to push the reinforcement connecting rod 203d-1 to reset. The elastic spring plate 203d-4 is designed as a wavy structure, which can not only provide restoring force, but also evenly disperse the pressure when under pressure to increase the service life. The extrusion block 203d-6 set at the upper end of the reinforcement lock buckle 203d-2 is parabolic, which makes it convenient for the fireproof frame 201 to slide in the installation slide groove 203b without causing obstruction.

[0045] Operation process: When performing fire prevention work on a hydraulic excavator, first confirm that the hydraulic excavator is in a stopped state, disconnect the power supply, ensure safe operation, check whether there are foreign objects inside and outside the equipment chassis 101, ensure that there are no obstacles around the inspection window 102 and the heat dissipation window 103, insert the installation slider 203c on the fireproof frame 201 into the installation slide groove 203b, and then slide along the travel direction of the reinforcement slide groove 203d-5. During this period, observe the cooperation between the installation slider 203c and the reinforcement slide groove 203d-5 to ensure that there is no jamming. During the sliding process, the fireproof frame 201 first contacts The extrusion block 203d-6 on the reinforcement lock buckle 203d-2 extrudes the reinforcement lock buckle 203d-2 along the movement of the fireproof frame 201, so that the reinforcement lock buckle 203d-2 is squeezed and contracted into the reinforcement slide groove 203d-5, which does not affect the sliding of the fireproof frame 201, thereby facilitating the sliding of the fireproof frame 201. After the fireproof frame 201 slides into place, one end of it is stuck on the reinforcement lock buckle 203d-2, and the fireproof frame 201 is pushed again along the force, so that the other end of the fireproof frame 201 is also stuck on the reinforcement lock buckle 203d-2, thereby realizing the installation of the fireproof frame 201.

[0046] Example 2

[0047] Reference Figure 5 and Figure 6, which is the second embodiment of the present invention, is based on the previous embodiment, and the difference is that the cleaning component 204 includes a vibration connecting plate 204a arranged on the mounting frame 203a, a vibration member 204b arranged on the vibration connecting plate 204a, a reset member 204c arranged on the vibration member 204b, and a locking member 204d arranged on the vibration member 204b.

[0048] The vibration connecting plate 204a is installed on the upper end of the mounting frame 203a, and the vibration connecting plate 204a and the mounting frame 203a are fixedly connected. The vibration connecting plate 204a is used to fix the vibration member 204b and the mounting reset member 204c.

[0049] The vibration member 204b includes a vibration groove 204b-1 opened on the vibration connecting plate 204a, a guide slide bar 204b-2 arranged in the vibration groove 204b-1, and a swing slide bar 204b-3 arranged on the guide slide bar 204b-2; the guide slide bar 204b-2 and the swing slide bar 204b-3 are slidably connected.

[0050] Among them, the vibration groove 204b-1 is opened on the side of the vibration connecting plate 204a, and the vibration groove 204b-1 is used to accommodate the guide slide bar 204b-2. The guide slide bar 204b-2 is arranged in an array along the parallel direction of the vibration groove 204b-1. The guide slide bar 204b-2 and the vibration groove 204b-1 are fixedly connected. The arrangement design of the guide slide bar 204b-2 is staggered to balance the force generated during vibration and reduce resonance. A swing slide bar 204b-3 is sleeved on two adjacent guide slide bars 204b-2. The swing slide bar 204b -3 is slidably connected with the guide slide bar 204b-2, and the swing slide bar 204b-3 is slidably connected with the vibration groove 204b-1, and a magnetic block is arranged under the swing slide bar 204b-3, and a magnetic block corresponding to the magnetic block on the swing slide bar 204b-3 is also fixedly connected to the fireproof cloth 202. In this way, during the swinging process of the swing slide bar 204b-3, the two magnetic blocks can be attracted to each other, so that the swing slide bar 204b-3 drives the fireproof cloth 202 to shake, thereby increasing the shaking frequency of the fireproof cloth 202 and achieving the cleaning effect.

[0051] The reset member 204c includes a reset ring 204c-1 sleeved on the guide slide bar 204b-2, and a reset spring 204c-2 sleeved on the guide slide bar 204b-2; the reset ring 204c-1 and the guide slide bar 204b-2 are slidably connected, the reset ring 204c-1 and the rocking slide bar 204b-3 are in conflict with each other, and the reset spring 204c-2 is located between the vibration groove 204b-1 and the rocking slide bar 204b-3.

[0052] Among them, a plurality of reset rings 204c-1 are sleeved on the guide slide bar 204b-2, the reset rings 204c-1 have a certain weight, and the reset rings 204c-1 and the guide slide bar 204b-2 are slidably connected. The reset spring 204c-2 is sleeved on the guide slide bar 204b-2, and cooperates with the reset rings 204c-1 to increase the vibration effect of the swing slide bar 204b-3.

[0053] The locking member 204d includes a locking frame 204d-1 arranged on the mounting frame 203a, a locking rod 204d-2 arranged on the locking frame 204d-1, and a locking protrusion 204d-3 arranged on the locking frame 204d-1; a magnetic block is arranged at the lower end of the locking protrusion 204d-3, and a magnetic block is arranged at the upper end of the swing slide bar 204b-3.

[0054] Among them, the positioning bracket 204d-1 is located on the left and right sides of the installation frame 203a, the positioning bracket 204d-1 and the installation frame 203a are rotatably connected, and a torsion spring is provided at the rotational connection between the positioning bracket 204d-1 and the installation, the positioning rod 204d-2 is located between the two positioning brackets 204d-1, the positioning rod 204d-2 and the two positioning brackets 204d-1 are fixedly connected, the positioning protrusions 204d-3 on the positioning rod 204d-2 are equal in number to the swing slide bar 204b-3, and the positioning rod 204d-2 is fixedly connected to the two positioning brackets 204d-1, and ... protrusions 204d-3 on the positioning rod 204d-2 are fixedly connected to the two positioning brackets 204d-1, and the positioning protrusions 204d-3 on the positioning protrusions 204d-3 on the swing slide bar 204b-3 are fixedly connected to the two positioning brackets 204d-1, and the positioning protrusions 204d-3 on the positioning protrusions 204d-3 on the swing slide bar 204b-3 are fixedly connected to the two positioning brackets 204d-1, and the positioning protrusions 204d-3 on the positioning protrusions 204d-3 on the A magnetic block is arranged at a position corresponding to the lower end of the positioning protrusion 204d-3 and the swing slide 204b-3, and a magnetic block corresponding to it is arranged at the upper end of the swing slide 204b-3. In this way, when the swing slide 204b-3 is not in use, the positioning protrusion 204d-3 on the positioning rod 204d-2 can be used to absorb the swing slide 204b-3 to limit the swing slide 204b-3. In this way, the swing slide 204b-3 can be limited when it is not in use, thereby extending the service life of the swing slide 204b-3.

[0055] The rest of the structure is the same as that of Example 1.

[0056] Operation process: When a large amount of dust and impurities are attached to the surface of the fireproof cloth 202, in order to ensure the filtering effect and air permeability of the fireproof cloth 202, the surface of the fireproof cloth 202 needs to be cleaned. At this time, the positioning bracket 204d-1 is flipped, so that the positioning bracket 204d-1 and the positioning rod 204d-2 are flipped along the axis, and the positioning protrusion 204d-3 on the positioning rod 204d-2 is separated from the swing slide bar 204b-3. After separation, as the equipment in the equipment chassis 101 vibrates during operation, the swing slide bar 204b-3 is driven to swing up and down. During the swinging process, the fireproof cloth 202 also swings accordingly, and the magnetic block on the swing slide bar 204b-3 is close to the fireproof cloth 202. The magnetic block makes the two absorb each other, so that the swing slide bar 204b-3 can drive the fireproof wrapping cloth 202 to shake greatly. During the shaking process, the impurities attached to the fireproof wrapping cloth 202 are detached, and the fireproof wrapping cloth 202 is cleaned. After the cleaning is completed, when the equipment is turned off, the shaking of the swing slide bar 204b-3 disappears. By flipping the positioning bracket 204d-1, the positioning protrusion 204d-3 on the positioning rod 204d-2 is absorbed onto the swing slide bar 204b-3. After limiting the swing slide bar 204b-3, the magnetic block on the swing slide bar 204b-3 and the magnetic block on the fireproof wrapping cloth 202 are manually separated, thereby completing the cleaning of the fireproof wrapping cloth 202.

[0057] Example 3

[0058] Reference Figure 1 to Figure 7 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: the exhaust component 205 includes an exhaust air box 205a arranged on the mounting frame 203a, an exhaust air duct 205b arranged in the exhaust air box 205a, and a driving member 205c arranged on the exhaust air duct 205b.

[0059] The exhaust air box 205a is located at the lower end of the mounting bracket 203a, and the outer surface of the exhaust air box 205a is coated with a heat dissipation and cooling material, which can effectively isolate the external temperature, prevent the exhaust air duct 205b from overheating and melting due to excessive temperature, and protect the exhaust air duct 205b. The two ends of the exhaust air box 205a are rotatably connected to the mounting bracket 203a, and a torsion spring is provided at the connection between the mounting bracket 203a and the exhaust air box 205a. The exhaust air duct 205b is located on the inner wall of the exhaust air box 205a, and an air outlet is provided on the exhaust air duct 205b. The exhaust air duct 205b is made of rubber. The material has a certain elasticity. Through the drive of the driving member 205c, the exhaust air duct 205b expands and pushes the exhaust air box 205a, until the exhaust air duct 205b expands to a certain extent, the air outlet at its upper end opens to spray out gas, and the gas blows the dust and impurities on the surface of the fireproof wrap 202 along the direction of movement. Cooperating with the vibrating member 204b, the cleaning effect can be improved. The air outlet retracts after spraying gas, so that the exhaust air box 205a is reset. During the resetting process, the gas path direction can be guided, so that the gas can be sprayed in a semi-arc shape, thereby increasing its spraying range and further improving the cleaning effect.

[0060] The driving member 205c includes an extrusion airbag 205c-1 arranged in the vibration container 204b-1, a connecting pipe 205c-2 arranged on the extrusion airbag 205c-1, and an airflow pipe 205c-3 arranged on the connecting pipe 205c-2; the airflow pipe 205c-3 is located between the connecting pipe 205c-2 and the exhaust air duct 205b.

[0061] Furthermore, the extrusion airbag 205c-1 is located at the lower end of the rocking slide bar 204b-3 in the vibration groove 204b-1. The rocking slide bar 204b-3 slides on the guide slide bar 204b-2, and the extrusion airbag 205c-1 is pressed back and forth, so that the gas in the extrusion airbag 205c-1 enters the airflow pipe 205c-3 along the connecting pipe 205c-2, and then enters the exhaust air duct 205b from the airflow pipe 205c-3, thereby realizing gas pressurization in the exhaust air duct 205b. The number of connecting pipes 205c-2 corresponds to the extrusion airbag 205c-1, and a one-way valve is provided on the connecting pipe, which can effectively control the flow path of the gas and realize the transmission and storage of gas. The airflow pipe 205c-3 is located between the connecting pipe 205c-2 and the exhaust air duct 205b, and is used for gas transmission and pressurization.

[0062] The rest of the structure is the same as that of Example 2.

[0063] Operation process: When cleaning the fireproof wrapping 202, during the cleaning process, the swing slide bar 204b-3 slides up and down to resist the squeezing air bag 205c-1, so that the gas in the squeezing air bag 205c-1 enters the exhaust air duct 205b along the connecting pipe 205c-2. The exhaust air duct 205b expands under the action of the gas pressure, and its air outlet opens. The rapidly ejected gas carries the loose dust and impurities on the surface of the fireproof wrapping 202, thereby achieving efficient cleaning. After the cleaning is completed, the air flow weakens, and the exhaust air duct 205b is reset under the action of the torsion spring, and the air outlet is closed. The cleaning effect is checked, and if necessary, the cleaning cycle can be repeated.
