[0022] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0023] The utility model provides a water tank cover, such as Figure 1-3 As shown, a water tank cover of an embodiment includes a water tank cover body 10 and a water tank cover front cover 20, the water tank cover front cover 20 is connected to the water tank cover body 10, the water tank cover front cover 20 includes a grille body 21 and a grille plate 22, the grille body 21 includes a support plate 211 and a frame 212, both ends of the support plate 211 are respectively fixedly connected to the frame 212, the grille plate 22 is provided with a card slot 221, the card slot 221 is for the support plate 211 to be placed, the grille plate 22 is plugged in at a specific angle through the card slot 221, the specific angle is the angle between the grille plate 22 and the plane where the grille body 21 is located, and the specific angle can be adjusted ( Figure 3The direction of the middle arrow represents the direction in which the grille plate 22 is adjusted to a specific angle), and two side walls of the slot 221 in the second direction partially abut against the support plate 211 .

[0024] Specifically, in this embodiment, the radiator cover front cover 20 is detachably connected to the radiator cover body 10. The support plate 211 has a length extending along a first direction, and the grille plate 22 has a length extending along a second direction, and the first length is perpendicular to the second length. Of course, the length direction of the grille plate 22 may not be perpendicular to the length direction of the support plate 211, and those skilled in the art may set the grille plate 22 to intersect with the support plate 211 according to actual conditions, which is not limited here.

[0025] In the water tank cover of the utility model, the installation and disassembly of the grille plate 22 are more convenient through the snap connection between the grille plate 22 and the support plate 211, and it is easy to maintain during the later use without replacing the overall structure, and the maintenance cost is low; after the grille plate 22 is connected to the support plate 211, it can have a specific angle with the plane where the grille body is located, while ensuring the exhaust volume of the heat sink and eliminating the safety hazard of the heat sink stopping working due to excessive temperature, it can prevent gravel particles from entering the water tank cover and damaging the heat sink.

[0026] For ease of description and understanding, refer to Figure 1 In the coordinate system, the first direction is defined as the Z-axis direction, that is, the up-down direction, where the positive direction of the Z-axis is upward and the negative direction of the Z-axis is downward; the second direction is defined as the X-axis direction, that is, the left-right direction, where the positive direction of the X-axis is right and the negative direction of the X-axis is left; the third direction is defined as the Y-axis direction, that is, the front-back direction, where the positive direction of the Y-axis is front and the negative direction of the Y-axis is back.

[0027] It should be noted that in this embodiment, the length direction of the grid plate 22 is the left-right direction, the length direction of the support plate 211 is the up-down direction, and the plane where the grid body 21 is located described herein is a plane perpendicular to the horizontal plane. It can be understood that the specific angle can be the angle between the grid plate 22 and the horizontal plane.

[0028] In this embodiment, please refer to Figure 4-5There are multiple grille plates 22, and the multiple grille plates 22 are parallel and spaced in the up-down direction. Each grille plate 22 is plugged and matched with the support plate 211 at a specific angle through the slot 221. Specifically, the matching connection between the slot 221 and the support plate 211 is an interference fit, and the slot width of the slot 221 in the left-right direction is less than or equal to the width of the support plate 211 in the left-right direction. When the slot width of the slot 221 is equal to the width of the support plate 211, the minimum interference is equal to 0, and the side wall of the slot 221 contacts the support plate 211 with friction to prevent the grille plate 22 from sliding down; when the slot width of the slot 221 is less than the width of the support plate 211, the slot 221 is inserted into the support plate 211, and the two side walls of the slot 221 abut against the support plate 211 and exert pressure to squeeze the support plate 211 to prevent the grille plate 22 from sliding down. The grille plate 22 is mounted on the support plate 211, that is, the grille plate 22 is engaged with the support plate 211 through the slot 221, and the grille plate 22 moves toward the support plate 211 until the support plate 211 is engaged with the slot 221, at which time the movement of the grille plate 22 in the left and right directions is restricted, and at the same time, the movement of the grille plate 22 in the up and down directions is also restricted because of the interference fit between the support plate 211 and the slot 221. The grille plate 22 is plugged and matched with the support plate 211 forward in a direction perpendicular to the plane where the grille body 21 is located, and at this time, the specific angle between the grille plate 22 and the plane where the grille body 21 is located is 90°. When a specific angle less than 90° is required, the grille plate 22 is pulled backward so that the bottom of the slot 221 is a certain distance away from the support plate, that is, the side of the support plate 211 close to the grille plate 22 is not in contact with the bottom of the slot 221, giving the grille plate 22 an escape space to adjust the specific angle. The grille plate 22 can be rotated upward or downward so that the grille plate 22 and the plane where the grille body 21 is located have a specific angle less than 90°.

[0029] It can be understood that before the grille plate 22 is installed on the support plate 211, the specific angle between it and the plane where the grille body 21 is located can be adjusted in advance, and the support plate 211 can be approached along the direction of the specific angle so that the support plate 211 is engaged with the slot 221, and the support plate 211 abuts against the bottom of the slot 221 to achieve the installation of the grille plate 22.

[0030] The overall integrated front cover requires more time and labor in the preparation process. In this embodiment, the grille plate 22 is connected to the support plate 211 by opening a slot 221, so that the installation and disassembly of the grille plate 22 is more convenient. The assembly process requires explanation and is easy to maintain during later use. There is no need to replace the overall structure, and the maintenance cost is low.

[0031] In this embodiment, there are multiple support plates 211, and there are multiple slots 221 on each grille plate 22. The number of support plates 211 corresponds to the number of slots 221 on a single grille plate 22, and multiple slots 221 are distributed on the grille plate 22 at intervals along the left-right direction. Specifically, there are 9 support plates 211 in this embodiment, and the number of corresponding slots 221 on a single grille plate 22 is 9. Each slot 221 is correspondingly engaged and connected to a support plate 211, which increases the friction area between the grille plate 22 and the support plate 211, and the friction force is greater. After the grille plate 22 is plugged into the support plate 211, it is not easy to slide down due to its own gravity. Of course, the number of support plates 211 and the number of slots 221 do not necessarily have to be completely corresponding and equal. Those skilled in the art can set the number of support plates 211 to 3, 4, 5, 6, 7, 8, 10, 11, etc. according to actual conditions, and no unique limitation is made here; those skilled in the art can set the number of slots 221 on a single grille plate 22 to 3, 4, 5, 6, 7, 8, 10, 11, etc. according to actual conditions, and no unique limitation is made here.

[0032] In this embodiment, the ratio of the depth of the card slot 221 in the front-to-back direction to the width of the grille plate 22 extending in the front-to-back direction is 1:5 to 1:3. Those skilled in the art can set the ratio of the two to 1:5, 1:4, 1:3, etc. according to actual conditions, and this is not the only limitation. It should be noted that if the depth of the card slot 221 is too deep, it may reduce the stability during plug-in matching, increase the difficulty of assembly, and even affect the function of the parts and the strength of the overall structure. In this embodiment, the depth of the card slot 221 opened on the grille plate 22 is set without affecting the connection stability, function and overall structural strength of the grille plate 22.

[0033] In this embodiment, please refer to Figure 6-7 The specific angle φ is preferably 45° to 90°. The grille plate 22 is close to and installed on the support plate 211 along the front-rear direction, and the grille plate 22 is kept parallel to the horizontal plane (the angle between the grille body plane is 90°, the angle between the grille body plane and the horizontal plane is 0, and the specific angle is 90°). Figure 7The direction of the middle arrow represents the direction of rotation of the grille plate 22. In this embodiment, the grille plate 22 after being plugged in with the support plate 211 is tilted downward relative to the horizontal plane. This arrangement can protect the device in the water tank cover to the greatest extent while ensuring the normal exhaust and heat dissipation of the heat dissipation device in the water tank cover. During the work in the mining environment, gravel particles are not easy to enter the water tank cover. When the gravel particles contact the grille plate 22 in this state, they automatically fall due to the downward tilt of the grille plate 22, which plays a certain protective role. When the angle between the grille plate 22 and the horizontal plane is 0, the grille plate 22 is in a fully open state. At this time, the ventilation is good. It is used in construction to maximize the air inlet and outlet of the power system and increase the heat dissipation capacity of the system. It should be noted that the grille plate 22 after being plugged in with the support plate 211 can also be tilted upward relative to the horizontal plane. It can be understood that technicians in this field can set the value of the specific angle to 45°, 48°, 50°, 52°, 55°, 57°, 60°, 65°, 67°, 69°, 70°, 75°, 78°, 80°, 86°, 90°, etc. according to actual conditions, and no sole limitation is made here.

[0034] In this embodiment, the frame 212 includes a first bending plate 2121, a second bending plate 2122 and a connecting plate. The first bending plate 2121, the connecting plate and the second bending plate 2122 are fixedly connected in sequence to form a frame shape. Specifically, the first bending plate 2121 includes a first plate segment and a second plate segment connected in sequence, the second bending plate 2122 includes a third plate segment and a fourth plate segment connected in sequence, the first bending plate 2121 and the second bending plate 2122 are mirror-distributed on both sides of the up-down direction, the connecting plate includes a first connecting plate 2123, a second connecting plate 2124, a third connecting plate 2125 and a fourth connecting plate 2126, the length direction of the first connecting plate 2123 and the length direction of the third connecting plate 2125 are both parallel to the left-right direction, The length direction of the second connecting plate 2124 and the length direction of the fourth connecting plate 2126 are both parallel to the up and down directions, one end of the first plate segment and one end of the third plate segment are fixedly connected through the first connecting plate 2123, the second connecting plate 2124, the third connecting plate 2125 and the fourth connecting plate 2126 are fixedly connected in sequence, one end of the second connecting plate 2124 away from the third connecting plate 2125 is fixedly connected to the second plate segment, and one end of the fourth connecting plate 2126 away from the third connecting plate 2125 is fixedly connected to the fourth plate segment.

[0035] In this embodiment, the multiple grid plates 22 include short grid plates and long grid plates, the short grid plates are located between the first plate segment and the third plate segment, and the two ends of the short grid plates are fixedly connected to the first plate segment and the third plate segment, the long grid plates are located between the second connecting plate 2124 and the fourth connecting plate 2126, and the two ends of the long grid plates are fixedly connected to the second connecting plate 2124 and the fourth connecting plate 2126.

[0036] In this embodiment, the water tank cover body 10 includes a connecting bracket 11, a fixed block 23 is fixedly connected to the grille plate 22, and the fixed block 23 is detachably connected to the connecting bracket 11. Specifically, a connecting through hole is provided on the fixed block 23, and a threaded seat is installed on the connecting bracket 11. The fastener passes through the connecting through hole and the threaded seat to fix the fixed block 23 and the connecting bracket 11.

[0037] Specifically, there are multiple connecting brackets 11, and the multiple connecting brackets 11 are distributed along the frame 212 and close to the frame 212, and the grid plate 22 is fixedly connected with a fixed block 23 that cooperates with the connecting bracket 11. It should be noted that only some of the multiple grid plates 22 need to be fixedly connected with the fixed block 23 and cooperate with the connecting bracket, and the grid plate 22 fixed with the fixed block 23 can no longer be adjusted to a specific angle after being fixedly linked with the connecting bracket 11, and the grid plate 22 fixed with the fixed block 23 can be adjusted to a specific angle.

[0038] It is understandable that the fixed block 23 can also be fixed on the frame 212, and each connecting bracket 11 corresponds to a fixed block 23 and is detachably connected thereto. The fixed block 23 is installed on the frame 212, which will not affect the adjustment of some grid plates 22 to a specific angle, so that each grid plate 22 can be freely adjusted.
