Description

Technical Field

[0001] This utility model relates to the field of heat dissipation window technology, and in particular to an adjustable heat dissipation window and engineering equipment. Background Technology

[0002] In recent years, with the continuous improvement of the performance of large rock drilling rigs, the diameter and depth of drilling holes have increased rapidly. Furthermore, with the continuous expansion of overseas markets, these rigs need to adapt to various low and high temperature conditions during operation. This places higher demands on the overall heat dissipation and heat storage capabilities of the machine. The power system's heat dissipation is a crucial component of the overall heat dissipation. Currently, the power system's heat dissipation is mainly achieved through radiators. The radiator exhausts hot air through louvers, and the angle of the louver blades determines the amount of heat dissipation per area. The heat dissipation per area is greatest when the blades are horizontal. Currently, the construction machinery industry primarily considers large-area heat dissipation, so louvers are welded and fixed horizontally or at a certain angle. This results in louvers being in a fixed state, unable to be adjusted according to actual working conditions, lacking flexibility. Simultaneously, the industry lacks louvers that can completely close under extremely low temperature conditions, making it impossible to retain the heat generated by the engine for starting other components. This leads to equipment being unable to operate continuously in extremely low temperature conditions such as those in Russia, and only able to resume operation after the temperature rises. Common louvered windows on the market are generally used in normal temperature conditions and are mostly static in homes or offices. In the field of construction machinery, when the equipment is in operation, the vibration amplitude of the whole machine is quite large, so common louvered windows are not suitable for the field of construction machinery.

[0003] Therefore, there is an urgent need for an adjustable heat dissipation window and engineering equipment that can be applied to engineering equipment, and whose blade angle is flexibly adjustable to adapt to various low and high temperature weather conditions. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable heat dissipation window and engineering equipment, aiming to solve the technical problem that traditional louvers / heat dissipation window blades are not adjustable or their structure is unsuitable for use in engineering equipment.

[0005] To achieve the above objectives, in a first aspect, this utility model provides an adjustable heat dissipation window, including a fixed frame, a movable frame and several heat dissipation plates, as well as an adjustable locking mechanism;

[0006] Several heat dissipation plates are spaced apart from top to bottom between the fixed frame and the movable frame. Each heat dissipation plate is hinged to both sides of the fixed frame on one side and to both sides of the movable frame on the other side.

[0007] The adjustable locking mechanism includes a push rod, a rotating plate, and a thrust rod, as well as a sliding groove, several locking grooves, and several limiting blocks, all of which are provided at the bottom of one side of the fixed frame.

[0008] One end of the rotating plate is rotatably connected to one side of the fixed frame, one end of the push rod passes through the other end of the rotating plate and is fixedly connected to the movable frame, and the other end of the push rod is slidably disposed in the slide groove;

[0009] The thrust rod passes through the other end of the push rod, with one end operably locked in the corresponding locking groove and the other end operably touching the bottom of the corresponding limit block to achieve a limit.

[0010] As a further improvement to the above solution, a sealing strip is provided at one edge of the heat sink for sealing with the equipment frame or adjacent heat sinks.

[0011] As a further improvement to the above solution, the push rod includes a first straight rod body and first bent portions disposed at both ends of the first straight rod body. The first bent portion at one end is fixedly connected to the movable frame through the rotating plate, and the first bent portion at the other end is slidably disposed in the slide groove.

[0012] Furthermore, a through hole is provided on the bent portion at the other end, allowing the thrust rod to rotatably pass through.

[0013] As a further improvement to the above solution, the thrust rod includes a second straight rod body and a second bent portion disposed at one end of the second straight rod body; the second bent portion is used to be operably engaged in the locking groove of the heat sink at the corresponding rotation angle, and the end of the second straight rod body is used to operably abut against the bottom of the corresponding limiting block.

[0014] As a further improvement to the above solution, a number of the locking grooves are spaced apart on one side of the slide groove, and a number of the limiting blocks are arranged in pairs on the other side of the slide groove.

[0015] Each of the locking slots is provided with a pair of limit blocks so that the thrust rod can be engaged to lock the position of the heat sink at the corresponding rotation angle.

[0016] As a further improvement to the above solution, the locking groove is a U-shaped groove with the opening facing upward, so that the second bent part of the thrust rod can be engaged;

[0017] The pair of limiting blocks are staggered and spaced on one side of the outer wall of the fixed frame, and the gap between the two limiting blocks forms a limiting space for the second straight rod body of the thrust rod to be inserted.

[0018] As a further improvement to the above solution, the fixing frame includes a first fixing plate and a second fixing plate, which are arranged opposite to each other so that the two ends of one side of the heat sink can be hinged together.

[0019] The first fixing plate includes a first plate body and a first bent plate disposed at one end of the first plate body, the first bent plate being used for fixed installation with the equipment;

[0020] The second fixing plate includes a second plate body and a second bent plate disposed at one end of the second plate body. The second bent plate is used for fixed installation with the equipment. An extension is provided at the bottom of the second plate body facing the movable frame direction. The slide groove, several locking grooves and several limiting blocks are all disposed on the extension.

[0021] As a further improvement to the above solution, the movable frame includes two symmetrically arranged vertical plates for hinged connection at both ends of the other side of the heat sink.

[0022] Secondly, this utility model also provides an engineering device, including the adjustable heat dissipation window described in the first aspect.

[0023] Because this utility model adopts the above technical solutions, the beneficial effects of this application are as follows:

[0024] This utility model provides an adjustable heat dissipation window, including a fixed frame, a movable frame, and several heat dissipation plates, as well as an adjustable locking mechanism. The heat dissipation plates are spaced apart from top to bottom between the fixed frame and the movable frame. Each heat dissipation plate has two ends hinged to the two sides of the fixed frame on one side and two ends hinged to the two sides of the movable frame on the other side. This arrangement allows the movable frame to be pushed, causing the heat dissipation plates to rotate around their hinge points with the fixed frame. The heat dissipation plates can be rotated to be parallel to the horizontal plane (i.e., fully open), at a preset angle (preferably 45°), or perpendicular to the horizontal plane (i.e., fully closed). An adjustable locking mechanism is also provided, which can be configured with locking grooves and limiting blocks of corresponding positions according to actual needs, enabling the heat dissipation plates to be locked at the preset rotation angle. The adjustable heat dissipation window allows the heat dissipation plate to be adjusted to a fully open, half-open, or fully closed state according to the ambient temperature of the equipment. In the corresponding state, the adjustable locking mechanism uses a push rod to lock the heat dissipation plate to the corresponding locking groove and limit block. Compared to traditional fixed heat dissipation windows, this adjustable heat dissipation window allows for flexible adjustment of the heat dissipation plate's opening state according to the ambient temperature to meet the heat requirements of the engineering equipment. Compared to traditional adjustable louvers, this adjustable heat dissipation window has a simple and reliable structure. The push rod drives the movable frame to rotate the heat dissipation plate at different angles, achieving different opening states. The adjustable locking mechanism uses a mechanical locking groove and limit block to achieve adjustable locking, resisting high-frequency vibrations of the engineering equipment.

[0041] Example 1

[0042] See Figures 1-6 This utility model provides an adjustable heat dissipation window, including a fixed frame 1, a movable frame 2 and several heat dissipation plates 3, as well as an adjustable locking mechanism 4;

[0043] Several heat dissipation plates 3 are spaced apart from top to bottom between the fixed frame 1 and the movable frame 2. Each heat dissipation plate 3 has two ends on one side hinged to the two sides of the fixed frame 1, and two ends on the other side hinged to the two sides of the movable frame 2. Specifically, pushing the movable frame 2 can cause the heat dissipation plate 3 to rotate around the hinge point with the fixed frame 1, so that the heat dissipation plate 3 can rotate to be parallel to the horizontal plane (i.e., the heat dissipation plate 3 is in a fully open state), or to a preset angle (preferably the preset angle is 45°), or perpendicular to the horizontal plane (i.e., the heat dissipation plate 3 is in a fully closed state).

[0044] The adjustable locking mechanism 4 includes a push rod 41, a rotating plate 42 and a thrust rod 43, as well as a sliding groove 44, a number of locking grooves 45 and a number of limiting blocks 46, all of which are provided at the bottom of one side of the fixed frame 1.

[0045] One end of the rotating plate 42 is rotatably connected to one side of the fixed frame 1. Specifically, one end of the rotating plate 42 is rotatably connected to one side of the fixed frame 1 via a pin 6.

[0046] One end of the push rod 41 passes through the rotating plate 42, and the other end is fixedly connected to the movable frame 2. The other end of the push rod 41 is slidably disposed within the slide groove 44. Specifically, the slide groove 44 has an arc-shaped slide groove 44 with a preset curvature. The push rod 41 includes a first straight rod body 411 and first bent portions 412 disposed at both ends of the first straight rod body 411. The first bent portion 412 at one end passes through the rotating plate 42 and is fixedly connected to the movable frame 2. The first bend 412 at the other end is slidably disposed within the arc-shaped groove 44, and a through hole is provided on the bend 412 at the other end; when the push rod 41 is pushed, the first bend 412 at the other end, constrained by the arc-shaped groove 44, causes the movable frame 2 to rotate around the pin 6, thereby causing the heat sink 3 to rotate around the hinge point with the fixed frame 1, so that the heat sink 3 rotates to be parallel to the horizontal plane (i.e., the heat sink 3 is in a fully open state), or at a preset angle (preferably the preset angle is 45°, in a semi-closed state), or perpendicular to the horizontal plane (i.e., the heat sink 3 is in a fully closed state); and a through hole is provided on the bend 412 at the other end.

[0047] The thrust rod 43 passes through the through hole on the bent portion at the other end of the push rod 41, one end of which is operably locked in the corresponding locking groove 45, and the other end is operably pressed against the bottom of the corresponding limiting block 46 to achieve limiting.

[0048] Specifically, the thrust rod 43 includes a second straight rod body 431 and a second bent portion 432 disposed at one end of the second straight rod body 431. The second bent portion 432 is operably engaged in the locking groove 45 in the corresponding state, and the end of the second straight rod body 431 is operably abutted against the bottom of the limiting block 46 in the corresponding state.

[0049] In each corresponding state, a corresponding locking groove 45 and a limiting block 46 are provided on the bottom side of the fixed frame 1; in this embodiment, the heat sink 3 is provided in three states, and correspondingly, three locking grooves 45 are provided on the bottom side of the fixed frame 1, namely the first locking groove 45-1, the second locking groove 45-2 and the third locking groove 45-3.

[0050] See Figures 3-6 When the heat sink 3 is rotated to be parallel to the horizontal plane, that is, when the heat sink 3 is in a fully open state, the end of the second straight rod body 431 of the thrust rod 43 is pressed against the lower part of the corresponding limiting block 46, and then the thrust rod 43 is rotated so that its second bent part 432 is locked in the first locking groove 45-1, thereby locking the heat sink 3 in the fully open state.

[0051] See Figure 1When the heat sink 3 needs to be rotated to a 45° angle with the horizontal plane, that is, when the heat sink 3 is in a semi-closed state, first rotate the thrust rod 43 so that the second bent portion 432 of the thrust rod 43 rotates out of the first locking groove 45-1, releasing the constraint of the first locking groove 45-1 on the second bent portion 432; then pull the thrust rod 43 outward so that the end of the second straight rod body 431 disengages from the constraint of the corresponding limiting block 46; then push the push rod 41 to rotate the heat sink 3 to a semi-closed state, then bring the end of the second straight rod body 431 of the thrust rod 43 to the bottom of the corresponding limiting block 46, and then rotate the thrust rod 43 so that its second bent portion 432 is locked in the second locking groove 45-2, thereby locking the heat sink 3 in the semi-closed state; similarly, see Figure 2 When it is necessary to rotate the heat sink 3 to be perpendicular to the horizontal plane, that is, when the heat sink 3 is in a fully open state, first release the constraint of the push rod 43, then push the push rod 41 to drive the heat sink 3 to rotate to a fully closed state, and then operate the push rod 43 to lock the current state.

[0052] This design allows the adjustable heat dissipation window to adjust the heat dissipation plate 3 to a fully open, half-open, or fully closed state according to the ambient temperature of the equipment. In the corresponding state, the adjustable locking mechanism 4 locks the heat dissipation plate 3 to the corresponding locking groove 45 and the limiting block 46 via the push rod 43. Compared with traditional fixed heat dissipation windows, the adjustable heat dissipation window provided by this invention can flexibly adjust the opening state of the heat dissipation plate 3 according to the ambient temperature to meet the heat demand of the engineering equipment. Compared with adjustable louvers in traditional living scenarios, the adjustable heat dissipation window provided by this invention has a simple and reliable structure. By operating the push rod 41, the movable frame 2 is driven to rotate the heat dissipation plate 3 at different angles to achieve different opening states. The adjustable locking mechanism 4 achieves adjustable locking through the mechanical locking groove 45 and the limiting block 46, which can resist the high-frequency vibration of the engineering equipment.

[0053] In a preferred embodiment, a sealing strip 5 is provided at one edge of the heat sink 3 for sealing with the equipment frame or adjacent heat sink 3; the sealing strip 5, when the heat sink 3 is in a fully closed state, can prevent the heat generated by the equipment from dissipating from the gaps between the heat sink 3, thereby ensuring that the heat generated by the engineering equipment dissipates as little as possible in extremely cold environments.

[0054] In a preferred embodiment, a plurality of locking grooves 45 are spaced apart on one side of the slide groove 44, and a plurality of limiting blocks 46 are arranged in pairs on the other side of the slide groove 44.

[0055] Each of the locking grooves 45 is provided with a pair of limiting blocks 46, so that the thrust rod 43 can be inserted to lock the position of the heat sink 3 at the corresponding rotation angle.

[0056] Preferably, the locking groove 45 is a U-shaped groove with the opening facing upward, so that the second bent portion 432 of the thrust rod 43 can be engaged;

[0057] Pairs of limiting blocks 46 are staggered and spaced on one side of the outer wall of the fixed frame 1. The gap between the two limiting blocks 46 forms a limiting space for the second straight rod body 431 of the thrust rod 43 to be inserted.

[0058] The dual mechanical locking of the locking groove 45 and the limiting block 46 ensures the stability of the heat sink 3 in its current state, so that even high-frequency vibrations of the engineering equipment will not have an adverse effect on it.

[0059] In a preferred embodiment, the fixing frame 1 includes a first fixing plate 11 and a second fixing plate 12, with the two fixing plates arranged opposite to each other so that the two ends of one side of the heat sink 3 can be hinged together.

[0060] The first fixing plate 11 includes a first plate body and a first bent plate disposed at one end of the first plate body, the first bent plate being used for fixed installation with the equipment;

[0061] The second fixing plate 12 includes a second plate body and a second bent plate disposed at one end of the second plate body. The second bent plate is used for fixed installation with the equipment. An extension is provided at the bottom of the second plate body facing the movable frame 2. The sliding groove 44, a number of locking grooves 45 and a number of limiting blocks 46 are all disposed on the extension. The two fixing plates and the heat dissipation plate 3 disposed between the two fixing plates form a stable frame structure, so that the adjustable heat dissipation window can resist the high-frequency vibration of the equipment.

[0062] In a preferred embodiment, the movable frame 2 includes two symmetrically arranged vertical plates 21 for hinged connection at both ends of the other side of the heat sink 3.

[0063] Example 2

[0064] This utility model also provides an engineering device, including the adjustable heat dissipation window described in Embodiment 1; specifically, in this embodiment, a rock drilling rig is used as an example for illustration.

[0065] When the rock drilling rig is operating at high temperature, the engine will also generate a large amount of hot air. The combination of the two will cause the temperature of the whole machine to be very high, affecting the operation of other components. In order to reduce the temperature of the whole machine, the heat needs to be discharged outside the machine in time. At this time, the push rod 41 can be operated to make the heat sink 3 fully open, so that the hot air inside the rock drilling rig can be dissipated in time and fully.

[0066] When the rock drilling rig is operating at normal temperature, the engine will generate a lot of heat as it continues to work. However, considering that the external temperature is not high, the combination of the two will not cause the whole machine to get very hot in a short time. The push rod 41 can be operated to adjust the angle of the heat dissipation plate 3 to 45°. The heat dissipation plate 3 is in a semi-closed state. At this time, the space occupied by the heat dissipation plate 3 in the horizontal direction is reduced, which not only meets the heat dissipation needs of the whole machine, but also facilitates the movement of maintenance personnel.

[0067] When the rock drilling rig is operating at extremely low temperatures, the engine continuously generates a large amount of heat. However, due to the extremely low ambient temperature, some electrical and hydraulic components inside the machine do not work. At this time, it is necessary to retain the heat generated by the engine inside the machine to ensure normal operation. At this time, push rod 41 can be operated to make the heat dissipation plate 3 fully closed to prevent heat loss.

[0068] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
