Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the temperature control device and the reaction chamber using the same provided by the present invention are described in detail below with reference to the accompanying drawings.

The electric controller generates a large amount of heat in the working process, the electric controller is provided with the electric cabinet 1, and the heat can increase the temperature of air in the electric cabinet 1 and around the electric cabinet 1. The hot air is less dense and will flow upward. In the prior art, the protection structure is fixed above the electrical cabinet 1 to block the flow of hot air. The blocking of the protective structure causes hot air to accumulate above the electrical cabinet 1, so that the electrical cabinet 1 is surrounded by the hot air, and heat dissipation is affected.

The electrical controller protection device provided by the application has the structure as shown in fig. 1 and fig. 2, and comprises an environment monitoring mechanism, a protection mechanism 6 and a control mechanism. The environment monitoring mechanism is used for detecting environmental influence parameters outside the electrical cabinet 1, such as illumination intensity and rainfall outside the electrical cabinet 1. After detection, the environmental monitoring mechanism sends the environmental impact parameters to the control mechanism. The control mechanism is used for receiving the environmental impact parameters and judging whether the environmental impact parameters meet preset conditions. The protection mechanism 6 can move from a non-shielding position to a shielding position to shield the electrical cabinet 1. When the environmental impact parameters satisfy the preset conditions, the control mechanism can control the protection mechanism 6 to move to the shielding position. The structure of the control mechanism can refer to an MCU microcontroller and the like in the prior art, and is not described in detail herein.

The shielding position is located above the electrical cabinet 1. After the protection mechanism 6 moves to the shielding position, the projection of the protection mechanism 6 in the horizontal plane completely covers the electrical cabinet 1, so that the protection mechanism 6 can prevent sunlight from directly irradiating the electrical cabinet 1 or rain and snow from falling on the electrical cabinet 1. When the protection mechanism 6 is located at the non-shielding position, the space above the electrical cabinet 1 is open, and hot air generated in the operation process of the electrical controller can flow away from the upper side of the electrical cabinet 1.

In this embodiment, the electrical controller protection device shields the electrical cabinet 1 through the protection mechanism 6 when the environmental impact parameter satisfies the preset condition. When the environmental influence parameters do not meet the preset conditions, the protection mechanism 6 is in a non-shielding position, so that air above the electrical cabinet 1 can smoothly flow, and the electrical controller can have good heat dissipation conditions. The electric controller protection device has a good protection effect on the electric controller, has small influence on heat dissipation of the electric controller, and reduces the risk of safety accidents caused by poor heat dissipation of the electric controller.

In some embodiments, the environmental impact parameter comprises illumination intensity and/or precipitation. In a specific embodiment of the present application, the environment monitoring mechanism includes a photosensitive sensor 61 and a rain sensor 62, as shown in fig. 1 and fig. 2, a groove is provided in the middle of the top surface of the electrical cabinet 1, and both the photosensitive sensor 61 and the rain sensor 62 are fixed in the groove.

The photosensitive sensor 61 can detect the illumination intensity outside the electrical cabinet 1 in real time, and the rainfall sensor 62 can detect the rainfall outside the electrical cabinet 1 in real time. The process of determining whether the environmental impact parameter satisfies the preset condition may specifically include determining whether the illumination intensity is greater than a light intensity threshold and the precipitation amount is greater than a precipitation threshold, and if one of the determination results is yes, determining that the preset condition is satisfied. The control mechanism controls the protection mechanism 6 to shield the electrical cabinet 1. The user can set the specific values of the light intensity threshold and the precipitation threshold as required. For a specific implementation of the environmental impact parameter being one of the illumination intensity and the precipitation amount, reference may be made to the above embodiments, which are not described herein again. Of course, the environmental impact parameters are not limited to the illumination intensity and precipitation amount, but may also include temperature and the like.

In the present embodiment, the environment monitoring mechanism includes a photosensor 61 and a rain sensor 62. And the control mechanism judges whether the environmental influence parameters meet preset conditions or not according to the illumination intensity and the precipitation amount. When light intensity is stronger or rainfall is great, control mechanism control protection machanism 6 shields regulator cubicle 1, avoids illumination to cause the high temperature in regulator cubicle 1 to cause the electrical components 2 of electrical controller to damage, also can avoid in the rainwater infiltration regulator cubicle 1, causes electrical components 2 impaired or regulator cubicle 1 to corrode.

In some embodiments, the shielding mechanism 6 includes two shield plates 610 and a drive assembly. The driving assembly is connected to the two shielding plates 610, and the driving assembly can drive the two shielding plates 610 through translation, swing, and the like, and can also drive the shielding plates 610 to turn over, so that the shielding plates 610 can move from the non-shielding position to the shielding position. The structure of the driving assembly can refer to the prior art, such as a swing link mechanism, a guide rail sliding block mechanism and the like. Of course, the user may also adopt a structure of one shielding plate 610 or more than three shielding plates 610, and the driving component may drive the shielding plate 610 to move from the non-shielding position to the shielding position through translation, swing, turning, and the like.

As shown in fig. 1, the two shielding plates 610 are opposite to each other in the shielding position and are located above the electrical cabinet 1. The area of the two butted shielding plates 610 is larger than the area of the top surface of the electrical cabinet 1. The projections of the two shielding plates 610 on the horizontal plane can completely cover the electrical cabinet 1, and the electrical cabinet 1 is located in the middle of the projections of the two butted shielding plates 610 on the horizontal plane. The two shield plates 610 that are butted can effectively shield sunlight or rainwater.

As shown in fig. 2, the two shielding plates 610 are separated from each other in the non-shielding position and are located on both sides of the electrical cabinet 1. At this time, the two shielding plates 610 are away from the upper side of the electrical cabinet 1, so that the air above the electrical cabinet 1 can freely flow. The control mechanism can automatically control the driving component to drive the two shielding plates 610 to move from the shielding position to the non-shielding position when the environmental influence parameters or the related parameters meet the unfolding conditions. For example, for the case that the illumination intensity satisfies the preset condition, the temperature in the cabinet is lower than the temperature threshold value as the opening condition. For the case that the precipitation amount satisfies the preset condition, the illumination threshold value may be set as the start condition. The user may also set other starting conditions according to needs, which is not limited herein. In addition, the driving assembly can also drive the two shielding plates 610 to move from the shielding position to the non-shielding position under the manual control of an operator.

In some embodiments, the two shielding plates 610 have two abutting surfaces opposite to each other, a first limiting structure is disposed at one of the two abutting surfaces, and a second limiting structure is disposed at the other of the two abutting surfaces, and the first limiting structure and the second limiting structure cooperate when the two shielding plates 610 are located at the shielding position to limit the relative positions of the two shielding plates 610.

Optionally, the first limiting structure is a limiting hole 611, and the second limiting structure is a limiting post 612 for being inserted into and matched with the limiting hole 611. In the specific embodiment shown in fig. 2, the first limiting structure includes three limiting holes 611, the second limiting structure includes three limiting posts 612, and the positions of the limiting holes 611 and the positions of the limiting posts 612 correspond to each other. When the two shielding plates 610 are in the shielding position, the limiting column 612 is in inserted fit with the limiting hole 611, so that the two shielding plates 610 are ensured to be aligned, and water leakage caused by a gap between the two shielding plates 610 due to dislocation is avoided.

Optionally, the upper surface of the shielding plate 610 is a cambered surface. As shown in fig. 1, when both of the shielding plates 610 are in the shielding position, the height of the arc surface gradually decreases in a direction away from the middle of the abutting surface. Thus, rainwater falling on the shielding plate 610 will slide down along the edge of the arc-shaped plate facing the arc-shaped plate, and the rainwater is prevented from accumulating on the shielding plate 610. Of course, the upper surface of the shielding plates 610 may also adopt other structures, for example, the upper surface is formed by one or more inclined planes, so that when two shielding plates 610 are separated, rainwater accumulated above the two shielding plates 610 may be prevented from falling onto the electrical cabinet 1, which is not limited herein.

Optionally, the upper surface of the shielding plate 610 is further sprayed with a waterproof paint. The waterproof coating can prevent rainwater from directly contacting the shielding plate 610, enhance the waterproof performance of the shielding plate 610, prevent the rainwater from corroding the shielding plate 610, and prolong the service life of the shielding plate 610.

Optionally, a reinforcing frame is disposed on the lower side of the shielding plate 610, as shown in fig. 3, the reinforcing frame includes a plurality of first reinforcing ribs disposed parallel to the moving direction of the shielding plate 610 and at least one second reinforcing rib disposed perpendicular to the moving direction of the shielding plate 610, and the second reinforcing ribs intersect with all the first reinforcing ribs. The reinforcing frame can improve the overall structural strength of the shielding plate 610, and avoid damage to the shielding plate 610 due to wind load, collision and the like. Of course, the user may also use other structures of the reinforcing frame, which is not limited herein.

Optionally, the shielding plate 610 and the reinforcing frame are made of light materials, such as carbon fiber, polypropylene, polystyrene, and the like. In some embodiments of the present application, the electrical controller protection device is mounted on the electrical cabinet 1. The shielding plate 610 and the reinforcing frame are made of light materials, so that the overall weight of the shielding plate 610 can be reduced, and the problem that the center of gravity of the electric controller moves upwards to cause instability when the shielding plate 610 is in a shielding position can be avoided.

In this embodiment, the protection device of the electrical controller has two shielding plates 610, and the driving component drives the two shielding plates 610 to butt against each other or separate from each other. The two shield plates 610 are engaged in such a manner that a single shield plate 610 occupies a smaller space and is more conveniently arranged.

In some embodiments, the protection mechanism 6 further includes a telescopic assembly, the telescopic assembly is connected between the two shielding plates 610 and the driving assembly, and the driving assembly drives the two shielding plates 610 to move and generally drives the telescopic assembly to move synchronously. The telescopic assembly telescopically adjusts the distance between each of the two shielding plates 610 and the electrical cabinet 1. The structure of the telescopic assembly can refer to an electric cylinder, an air cylinder, a screw pair and the like in the prior art. In other embodiments, a user may also set a driving assembly to be connected between the telescopic assembly and the two shielding plates 610, and the telescopic assembly drives the driving assembly and the two shielding plates 610 to ascend and descend by telescoping, so as to adjust a distance between the two shielding plates 610 and the electrical cabinet 1, which is not limited herein.

Optionally, when the two shielding plates 610 are located at the shielding position, the control mechanism controls the driving assembly to drive the telescopic assembly to drive the shielding plates 610 to ascend and descend, so as to adjust the distance between each of the two shielding plates 610 and the electrical cabinet 1. When the electric controller needs to be heated for heat dissipation, the distance between the shielding plate 610 and the electric cabinet 1 is increased; when heat dissipation needs to be weakened, the distance between the shielding plate 610 and the electrical cabinet 1 is reduced. The control mechanism may determine that heat dissipation needs to be enhanced or reduced according to the temperature within the electrical cabinet 1 or the temperature of the electrical component 2.

Optionally, when the two shielding plates 610 are located at the non-shielding position, the telescopic assembly may drive the two shielding plates 610 to move toward the electrical cabinet 1, so as to reduce a distance between the shielding plates 610 and the electrical cabinet 1, and further reduce a space occupied by the electrical controller protection device.

In some embodiments, the drive assembly includes a driver, a transmission structure, and two oscillating structures. As shown in fig. 3, the driver is in transmission connection with the two swing structures through the transmission structure, and is used for driving the two swing structures to swing. The two swing structures are respectively connected with the two shielding plates 610, and are used for driving the two shielding plates 610 to separate from each other or butt against each other when swinging. Specifically, the driver may drive the two swing structures to swing in the same longitudinal plane, which may be parallel to the rear side of the electrical cabinet 1. The two swing structures swing downwards to drive the two shielding plates 610 to separate from each other; the two swing structures swing upward to drive the two shielding plates 610 to move upward and finally butt-joint with each other.

In some embodiments, the transmission structure includes a double-sided rack 64 and two gears 65. As shown in fig. 3 and 4, the driver is connected to the double-sided rack gear 64 for driving the double-sided rack gear 64 to reciprocate linearly. The driver can adopt an electric cylinder, an air cylinder, a hydraulic cylinder or the like, and in one specific embodiment of the application, the driver is the first electric push rod 63.

The double-sided rack 64 is located between and in meshing engagement with two gears 65. When the double-sided rack 64 makes a linear reciprocating motion, the two gears 65 can be synchronously driven to rotate. The two gears 65 are respectively connected with the two swing structures, and the two gears 65 respectively drive the two swing structures to swing when rotating. Of course, the user may also adopt transmission structures with other structures according to needs, for example, a worm and gear mechanism, a link mechanism, and the like, and the corresponding driver may also adopt devices such as a motor and the like, which is not limited herein. Taking a worm and gear mechanism as an example, the driver is a motor connected with the worm, and the motor drives the worm to rotate through the rotation of the worm, so that the swing structure swings.

Optionally, as shown in fig. 4, the swing structure includes a rod-shaped connecting arm 66 and a U-shaped connector, the gear 65 is fixed inside the U-shaped connector, and the connecting arm 66 is fixedly connected to a side of the web of the U-shaped connector, which is far away from the gear 65. One end of the connecting arm 66, which is far away from the gear 65, is connected to the shielding plate 610, and the connecting arm 66 swings around the center thereof when the gear 65 rotates, thereby moving the shielding plate 610 between the shielding position and the non-shielding position. Of course, the user may set the specific structure of the swing structure according to the requirement, which is not limited herein.

Optionally, the two gears 65 and the two swing structures are symmetrically distributed on two sides of the double-sided rack 64, and the two gears 65 drive the two swing structures to swing synchronously when rotating synchronously. Acting forces applied to the double-sided rack 64 by the two gears 65 are approximately equal, and the resultant force of the two gears is distributed on the straight line of the reciprocating motion of the double-sided rack 64, so that the connecting part of the double-sided rack 64 and the first electric push rod 63 is prevented from bearing bending moment, and the risk of fracture between the double-sided rack 64 and the first electric push rod 63 is reduced. The user may set the positional relationship between the two gears 65 and the double-sided rack 64 according to the requirement, which is not limited herein.

Alternatively, in the embodiment shown in fig. 3 and 4, the telescoping assembly includes two second power rams 68. In particular, the swing structure further comprises a right-angle frame 67. The right-angle stand 67 comprises a connecting plate and a protective plate which are perpendicular to each other, wherein the connecting plate is used for connecting the second electric push rod 68 and the connecting arm 66, and the protective plate can protect the connecting part and avoid collision of the connecting part in the carrying or running process. As shown in fig. 3, a connecting plate having a through hole penetrating in the thickness direction is connected to an end of the connecting arm 66 remote from the gear 65. The cylinder of the second electric push rod 68 is fixedly connected with one side of the periphery of the through hole close to the gear 65, and the piston of the second electric push rod 68 passes through the through hole and is connected with the shielding plate 610 through the connecting piece 69. The second electric push rod 68 can be connected to the arm 66 in parallel, and an included angle between the second electric push rod 68 and the shielding plate 610 is greater than 0 degree and less than 180 degrees, preferably 90 degrees.

Alternatively, as shown in fig. 4, a transverse cylinder 5 is arranged on the periphery of the through hole of the connecting plate and on the side close to the gear 65, and the cylinder of the second electric push rod 68 is fixed in the transverse cylinder 5. The transverse cylinder 5 can protect the second electric push rod 68, and sealing filler can be arranged in the transverse cylinder 5, so that rainwater and the like can be prevented from entering the transverse cylinder 5 to corrode the second electric push rod 68.

Optionally, in an embodiment where the two shielding plates 610 are limited by the first limiting structure and the second limiting structure, the two second electric push rods 68 may be located at the same initial position before the two shielding plates 610 are butted, so as to ensure that the first limiting structure and the second limiting structure can be smoothly matched. After the two shielding plates 610 are butted with each other, the two second electric push rods 68 can be synchronously extended and retracted, so that the two shielding plates 610 can be synchronously lifted and lowered, and the purpose of adjusting the distance between the shielding plates 610 and the electrical cabinet 1 is achieved. The user can use any stroke length of the two second electric push rods 68 as an initial position as required to ensure that the two shielding plates 610 can be smoothly butted.

In this embodiment, the driving component drives the shielding plate 610 to move between the shielding position and the non-shielding position in a swinging manner, so that the electric controller protection device occupies a smaller space. In addition, a telescopic assembly is further arranged in the protection mechanism 6, and the telescopic assembly can adjust the distance between the shielding plate 610 and the electrical cabinet 1, so that the air flow between the shielding plate 610 and the electrical cabinet 1 is adjusted, and the purpose of adjusting the heat dissipation effect of the electrical cabinet 1 is achieved.

In some embodiments, the electrical controller protective device further includes a mounting box 3. The mounting box 3 is fixed on one side of the electrical cabinet 1, a mounting cavity is formed between the mounting box 3 and the side wall, and the double-sided rack 64 and the two gears 65 are located in the mounting cavity. The driver is fixedly connected with the mounting box 3, and the driving end of the driver extends into the mounting cavity to be connected with the double-sided rack 64. The mounting box 3 is provided with two swing abdicating holes, and the two swing structures respectively penetrate through the two swing abdicating holes to extend to the inside of the mounting box 3 and are respectively connected with the two gears 65. The two swing structures are further provided with water baffles for shielding the swing abdicating holes when the swing structures swing to the mutual butt joint position of the two shielding plates 610. Of course, the user may also mount the protection mechanism 6 through a structure such as a mounting seat, and the electrical controller protection device may also be fixed on the ground or the like, which is not limited herein.

Alternatively, as shown in fig. 5, the mounting box 3 is fixed to the rear side wall of the electrical cabinet 1, and the protection mechanism 6 is connected to the rear side wall of the electrical cabinet 1 through the mounting box 3. The moving track of the water baffle does not interfere with the electrical cabinet 1, and the water baffle is prevented from colliding with the electrical cabinet 1. The electric controller protection device installation position can not cause the influence to opening of cabinet door, still can protect when the cabinet door is opened. Of course, the fixed position of the mounting box 3 does not limit the rear side wall of the electrical cabinet 1.

Alternatively, as shown in fig. 5, the mounting box 3 is cylindrical, and the axis of the mounting box is perpendicular to the rear side wall of the electrical cabinet 1. The rotating shafts of the two gears 65 are fixedly connected with the inner wall of the rear side of the mounting box 3, and the gears 65 rotate around the rotating shafts, so that the swinging structure can be driven to swing in a longitudinal plane parallel to the rear side wall of the electrical cabinet 1. Two swing abdicating holes are arranged on the side wall of the mounting box 3 and correspond to the motion tracks of the two swing structures respectively. The lateral wall of 3 lower parts of mounting box is equipped with the through-hole, and the mounting box 3 outside is equipped with the vertical section of thick bamboo 4 with through-hole periphery fixed connection. The first electric push rod 63 is fixed in the vertical cylinder 4, and a piston of the first electric push rod 63 penetrates through the through hole to be fixedly connected with the double-sided rack 64. The vertical tube 4 can protect the first electric push rod 63 from being collided or corroded by rainwater. Of course, the shape of the mounting box 3 is not limited to the cylindrical shape. In addition, the user may fix the driver in other manners as required, or fix the driver inside the mounting box 3, which is not limited herein.

Optionally, as shown in fig. 3, the length of the water guard is greater than or equal to the length of the swing abdicating hole, and the width of the water guard is greater than the width of the swing abdicating hole. The water baffle is specifically an arc-shaped water baffle 8, and the arc-shaped water baffle 8 can extend along the circumference surrounding the mounting box 3. One end of the arc-shaped water baffle 8 is fixedly connected with a right-angle frame 67 of the swing structure, and the other end of the arc-shaped water baffle is suspended. When the swing structure swings to the mutual butt joint position of the two shielding plates 610, the end parts of the two water baffles can be mutually attached, and rainwater is prevented from falling into the swing yielding hole from the position between the two water baffles. Of course, the user may use other shapes of the water baffle, and the water baffle may also be fixedly connected to the connecting arm 66, which is not limited herein.
