Description

Technical Field

[0001] The invention belongs to the technical field of radiation cooling paint spraying, and in particular relates to a device for spraying a cooling layer on the outside of an energy storage cabinet. Background Art

[0002] Radiative cooling materials are special functional materials that have both high reflectivity and selective high emissivity in the atmospheric window infrared band of 8-13μm wavelength. They mainly achieve cooling by emitting infrared rays with a wavelength of 8-13 microns. Infrared rays in this band are difficult to be absorbed by the atmosphere, so that the heat of surface objects is transferred to the low-temperature outer space in the form of infrared electromagnetic wave radiation, thereby achieving the purpose of radiative cooling.

[0003] Energy storage cabinets are currently widely used in outdoor charging stations and are usually directly exposed to the outdoors. A large number of capacitors are installed inside the energy storage cabinets. Therefore, it is necessary to control the temperature inside the energy storage cabinet within a reasonable range to avoid excessive temperature inside the energy storage cabinet to prevent capacitor damage and safety accidents. At present, the energy storage cabinet is mainly cooled by the air conditioning system, but the air conditioning refrigeration method alone has the problem of high energy consumption. Therefore, if the radiation refrigeration material can be applied to the energy storage cabinet, the energy storage cabinet itself can have a certain cooling function, so that the energy consumption of the air conditioner can be reduced. Radiative refrigeration materials are currently mainly in the form of radiation refrigeration film and radiation refrigeration coating. Among them, the combination of radiation refrigeration coating and energy storage cabinet is better and more durable, and the coating can adapt to various shapes and structural features of the outside of the energy storage cabinet. Because the radiation refrigeration coating only achieves the purpose of refrigeration mainly by reflection, it is usually only necessary to spray the radiation refrigeration coating on the side and top of the energy storage cabinet to form a refrigeration layer, and the cabinet body and cabinet door of the energy storage cabinet are usually sprayed separately and then assembled.

[0004] Currently, the refrigeration layer is mostly sprayed manually, but since manual spraying has high requirements for operators, there are problems such as uneven spraying, spraying omissions, and too thick a refrigeration layer, which affect the refrigeration effect of the energy storage cabinet. Summary of the invention

[0005] In order to solve the deficiencies of the prior art, the present invention provides a device for spraying an external refrigeration layer of an energy storage cabinet, which can automatically spray the cabinet body of the energy storage cabinet, thereby helping to improve the spraying quality and efficiency.

[0006] In order to achieve the purpose of the present invention, the following scheme is proposed: A device for spraying a refrigeration layer on the outside of an energy storage cabinet comprises a support component, a track and a spraying component.

[0007] The support assembly is used to place the cabinet body of the energy storage cabinet; The track includes a vertical section and a horizontal section arranged on the top of the vertical section, and an arc transition structure is formed between the vertical section and the horizontal section; The spray assembly includes a horizontally arranged main pipeline, and a plurality of fixed nozzles are connected along the length direction of the side of the main pipeline facing the support assembly; connecting pipes are coaxially passed through both ends of the main pipeline, and the connecting pipes are arranged movably along the axis, and branch pipes are arranged at the ends of the connecting pipes. The main pipeline and the two branch pipes are surrounded by a U-shaped structure, and the main pipeline is connected with the connecting pipe and the inside of the branch pipes; A plurality of countersunk holes are provided along the length direction on the opposite sides of the two branch pipes, a liquid outlet hole connected to the inside of the branch pipe is provided at the bottom of the countersunk hole, and a rotating nozzle is coaxially provided in the countersunk hole; a connecting hole connected to the inside of the rotating nozzle is provided at the rear end thereof, a counterweight block is provided on one side of the outer wall of the rotating nozzle, and the rotating nozzle is arranged to rotate around the axis in the countersunk hole; The spray assembly is arranged to move along the track. When the spray assembly moves along the vertical section of the track, the main pipe and the two branch pipes are in a horizontal state, the rotating nozzles on the two branch pipes are respectively facing the two sides of the cabinet, and the counterweight block is located below the rotating nozzle. At this time, the connecting hole is connected with the liquid outlet, and the fixed nozzle faces the back of the cabinet; when the spray assembly moves along the horizontal section of the track, the fixed nozzle faces the top surface of the cabinet, the rotating nozzles on the two branch pipes are respectively facing the two sides of the cabinet, and the counterweight block is located below the rotating nozzle. At this time, the connecting hole and the liquid outlet are staggered.

[0008] The beneficial effect of the present invention is that: this scheme sprays the two sides and the top surface of the energy storage cabinet by automated spraying, which has higher spraying efficiency than manual spraying, and can effectively ensure the spraying quality and improve the uniformity of the spraying thickness of the cooling layer, thereby ensuring the radiation cooling effect of the energy storage cabinet itself.

DETAILED DESCRIPTION

[0023] To make the objectives, technical solutions and advantages of the embodiments of the present invention more clear, the implementation modes of the present invention are described in detail below with reference to the accompanying drawings. However, the embodiments described in the present invention are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] like Figure 2 , Figure 5 As shown, a device for spraying a cooling layer on the outside of an energy storage cabinet comprises: a support component 1, a track 2 and a spraying component.

[0025] Specifically, the support assembly 1 is used to place the cabinet body of the energy storage cabinet. Since the bottom of the cabinet body does not need to be sprayed, as a common placement method, the cabinet body is placed in a use state, with the bottom surface of the cabinet body in contact with the support assembly 1, thereby exposing the side and top surfaces of the cabinet body.

[0026] Specifically, the track 2 includes a vertical section and a horizontal section arranged on the top of the vertical section. There is an arc transition structure between the vertical section and the horizontal section. As a preferred solution, only one track 2 can be provided, and its vertical section is arranged behind the support component 1, so that the horizontal section of the track 2 is located above the cabinet placed on the support component 1.

[0027] Specifically, Figure 7 , Figure 8 As shown, the spraying assembly includes a horizontally arranged main pipe 3, and a plurality of fixed nozzles 31 are connected along the length direction on one side of the main pipe 1 facing the supporting assembly 1, which are used to spray the back and top surfaces of the cabinet; connecting pipes 32 are coaxially penetrated at both ends of the main pipe 3, and the connecting pipes 32 are movably arranged along the axis, and branch pipes 4 are provided at the ends of the connecting pipes 32, and the branch pipes 4 are perpendicular to the main pipe 3, and the main pipe 3 and the two branch pipes 4 are combined to form a U-shaped structure, and the main pipe 3 is connected to the connecting pipe 32 and the branch pipes 4. In specific implementation, the main pipe 3, the connecting pipe 32 or the branch pipe 4 can be connected to the delivery pipeline of the refrigeration paint according to the pipeline layout.

[0028] Specifically, Figures 9 to 11 As shown, a plurality of countersunk holes 401 are provided along the length direction on the opposite sides of the two branch pipes 4, and a liquid outlet hole 402 connected to the inside of the branch pipe 4 is provided at the bottom of the countersunk hole 401. A rotating nozzle 41 is coaxially provided in the countersunk hole 401, and the front ends of the rotating nozzle 41 and the fixed nozzle 31 are both oriented toward the middle of the U-shaped structure. Specifically, the specific orientations of the fixed nozzle 31 and the rotating nozzle 41 can be horizontally set, or can be tilted upward or tilted downward; a connecting hole 411 connected to the inside of the rotating nozzle 41 is provided at the rear end of the rotating nozzle 41, and a counterweight block 42 is provided on one side of the outer wall of the rotating nozzle 41, and the rotating nozzle 41 is rotatably set around the axis in the countersunk hole 401.

[0029] The spraying assembly is arranged to move along the track 2, and when the spraying assembly moves on the vertical section and the horizontal section of the track 2, the spraying assembly sprays the cooling paint on the cabinet, thereby forming a cooling layer on the surface of the cabinet. Figure 2 , Figure 4 and Fig.10 As shown, when the spray assembly moves along the vertical section of the track, the U-shaped structure formed by the main pipe 3 and the two branch pipes 4 is in a horizontal state, and the rotating nozzles 41 on the two branch pipes 4 are respectively facing the two sides of the cabinet. Under the action of gravity, the counterweight block 42 will automatically be located below the rotating nozzle 41. At this time, the connecting hole 411 is connected to the liquid outlet 402, and the fixed nozzle 31 faces the back of the cabinet. In this state, the fixed nozzle 31 is used to spray the refrigeration paint on the back of the cabinet, and the rotating nozzles 41 on both sides of the cabinet are used to spray the side of the cabinet. Figure 5 , Figure 6 and Fig.11As shown, when the spray assembly moves along the horizontal section of the track, the main pipe 3 is located above the cabinet, the fixed nozzle 31 is facing the top surface of the cabinet, the U-shaped structure formed by the main pipe 3 and the two branch pipes 4 is in a vertical state, the two branch pipes 4 are respectively located on both sides of the cabinet, and the rotating nozzles 41 on the branch pipes 4 are respectively facing the two sides of the cabinet. Similarly, under the action of gravity, the counterweight block 42 will automatically be located below the rotating nozzle 41. At this time, the connecting hole 411 and the liquid outlet hole 402 are staggered, and the refrigeration paint inside the branch pipe 4 will not be able to be sprayed out through the rotating nozzle 41. In this state, only the fixed nozzle 31 is used to spray the top surface of the cabinet. This solution does not require a separate control mechanism to control the rotation of the rotating nozzle 41. When the spray assembly moves to the vertical section or horizontal section of the track 2, the rotating nozzle 41 will adaptively rotate under the action of the counterweight block 42, which can effectively simplify the structure of the spray assembly.

[0030] As a preferred movable setting structure, a circular ring can be set on the outer wall of the main pipe 3, and the track 2 can be designed to have a circular cross-section. The circular ring can be slidably mounted on the track 2 to achieve the connection between the spray assembly and the track 2, and a convex strip can be set on the outer wall of the track 2 along the track, and a key slot can be opened on the inner wall of the circular ring, and the convex strip and the key slot are used to form a connection to prevent the main pipe 3 from rotating around the axis of the track 2; the movement of the spray assembly can adopt the following scheme: the main pipe 3 is connected to a certain link of an annular chain, the annular chain is laid along the track of the track 2, and sprockets are set at the ends and arc corners of the track 2 for supporting and installing the annular chain, and a motor is connected to one of the sprockets, and the annular chain is driven by the motor to reciprocate along the track of the track 2, so as to drive the main pipe 3 to move back and forth along the track 2, thereby ultimately achieving the purpose of moving the spray assembly along the track 2. Preferably, the motor is connected to a sprocket disposed at the end of the track 2; and as common sense, in the specific design, a transition wheel or a tensioning wheel should be provided at the corner of the circular chain or at a location with a large overhang length to guide the circular chain to be arranged and moved along a predetermined trajectory and to achieve the purpose of tightening the chain.

[0031] As a preferred structure, when the connecting pipe 32 moves along the axis in the main pipe 3, the moving position of the connecting pipe 32 can be controlled by manual adjustment, and a screw is passed through the side of the end of the main pipe 3 to tighten the connecting pipe 32; in this scheme, the purpose of adjusting the connecting pipe 32 along the axis is to adjust the distance between the rotating nozzle 41 and the side of the cabinet and to make the spray device adapt to cabinets of different widths.

[0032] Preferably, in order to achieve the purpose of sealing, a plurality of sealing rings can be provided on the outer wall of the connecting pipe 32, and the sealing rings are used to seal the gap between the outer wall of the connecting pipe 32 and the inner hole of the main pipe 3. Because the rotating nozzle 41 is made of a large amount of plastic, it is impossible to set a rotating cylinder or motor for each rotating nozzle 41. In order to simplify the installation and control structure of the rotating nozzle 41, a counterweight block 42 is provided on the outer wall of the rotating nozzle 41 in this scheme. When the branch pipe 4 is in a horizontal or vertical state, the weight of the counterweight block 42 is used to drive the rotating nozzle 41 to rotate, thereby achieving the purpose of connecting or cutting off the connection between the counterbore 401 and the connecting hole 411; and the sealing ring is usually made of rubber, which will increase the friction between the sealing pairs, thereby affecting the rotation effect of the counterweight block 42 on the rotating nozzle 41. Therefore, it is not suitable to use a sealing ring to seal between the rotating nozzle 41 and the counterbore 401. In order to solve the above problems, Fig.10 , Fig.11 As shown, in this solution, a plurality of annular grooves 412 are opened on the outer wall of the end of the rotating nozzle 41, and the annular grooves 412 are used to form a sealed sealing structure between the rotating nozzle 41 and the counterbore 401. This structure not only plays a sealing role, but also avoids affecting the rotation of the rotating nozzle 41 by the counterweight block 42.

[0033] Preferably, when the rotating nozzle 41 is installed in the countersunk hole 401, in order to prevent the rotating nozzle 41 from falling off, a mounting retaining ring can be provided on one side of the branch pipe 4 where the countersunk hole 401 is provided for each rotating nozzle 41 to limit the position of each rotating nozzle 41 respectively, or a retaining bar 43 is provided on each branch pipe 4 to limit the rotating nozzle 41 on the branch pipe 4 at the same time.

[0034] Preferably, Figure 7 , Figure 8 As shown, the connecting pipe 32 is a U-shaped elbow structure, one end of the U-shaped elbow structure is inserted into the main pipe 3, and the other end is connected to the end of the branch pipe 4. There is a gap between the end of the branch pipe 4 and the front end of the fixed nozzle 31. This structure allows the two branch pipes 4 to have a smaller gap after they are close to the middle, so as to adapt to a smaller cabinet width. Fig.12 As shown, if the connecting pipe 32 is designed as a single straight pipe structure and the branch pipe 4 is connected to the end of the connecting pipe 32, then the minimum distance between the two branch pipes 4 after closing will be greater than or equal to the length of the main pipe 3, which cannot adapt to a cabinet with a smaller width.

[0035] Preferably, the distance between the front end of the rotating nozzle 41 and the root of the U-shaped elbow is equal to the length of the U-shaped elbow passing through one end of the main pipe 3, and the outer wall of the U-shaped elbow used to connect one end of the main pipe 3 is provided with a sealing structure. Preferably, the sealing structure is a rubber layer evenly arranged on the outer wall of the connecting pipe 32; the sealing structure can also be a sealing ring arranged on the outer wall of one end of the U-shaped elbow connected to the main pipe 3, and the sealing ring is close to the end of the U-shaped elbow; the connecting pipe 32 provided with a sealing structure can close the connecting structure between the fixed nozzle 31 corresponding to the side wall of the connecting pipe 32 and the main pipe 3 after being inserted into the main pipe 3, and the position of the closed fixed nozzle 31 is also just within the range between the front end of the rotating nozzle 41 and the root of the U-shaped elbow, so that this part of the fixed nozzle 31 can be prevented from spraying the refrigeration paint to the rotating nozzle 41, the U-shaped elbow and the end of the branch pipe 4, effectively avoiding the waste of refrigeration paint and keeping the various parts of the spraying assembly, especially the branch pipe 4, clean.

[0036] Further preferably, the length of the U-shaped elbow passing through one end of the main pipe 3 is greater than or equal to one quarter of the length of the main pipe 3 and less than or equal to one half of the length of the main pipe 3, so that the branch pipe 4 has a larger adjustment range.

[0037] Preferably, in order to prevent the connecting pipe 32 from rotating in the main pipe 3 and to ensure the stability of the relative position between the branch pipe 4 and the main pipe 3, the connecting pipe 32 and the main pipe 3 may be made of rectangular pipes.

[0038] As another preferred solution, Figure 3 , Figure 6 and Figure 7 As shown, the main pipe 3 has a rectangular tube structure, and the connecting pipe 32 has a circular tube structure to facilitate sealing with the inner wall of the main pipe 3. A U-shaped connecting plate 44 is provided at the end of the branch pipe 4. The two side plates of the U-shaped connecting plate 44 are connected to the side of the end of the branch pipe 4. The bottom of the U-shaped connecting plate 44 is slidably sleeved on the outer wall of the main pipe 3. In this way, the U-shaped connecting plate 44 can be used to increase the connection stability between the branch pipe 4 and the main pipe 3 and prevent the connecting pipe 32 from rotating around the axis of the main pipe 3.

[0039] Preferably, Figure 2 , Figure 6 , Figure 7As shown, a bidirectional screw 33 is provided in parallel on one side of the main pipe 3, and both ends of the bidirectional screw 33 have threads with opposite rotation directions. The two ends of the bidirectional screw 33 are respectively used to connect two branch pipes 4, so that the distance between the two branch pipes 4 can be adjusted by rotating the bidirectional screw 33 to adapt to cabinets of different widths and to adjust the distance between the rotating nozzle 41 and the side of the cabinet. In addition, by adopting this adjustment structure, not only can the branch pipes 4 be moved at the same time to improve the adjustment efficiency, but also after the adjustment, the position of the branch pipe 4 can be locked by the bidirectional screw 33 to prevent the branch pipe 4 from moving at will. The connection between the bidirectional screw 33 and the branch pipe 4 can be achieved in the following manner: the bidirectional screw 33 is set on the side of the main pipe 3 adjacent to the fixed nozzle 31, and an extension plate is set to the main pipe 3 at the end of the branch pipe 4, so that the bidirectional screw 33 passes through the extension plate by threaded connection, thereby realizing the connection between the bidirectional screw 33 and the branch pipe 4. As another preferred structure, such as Figure 6 As shown, the bidirectional screw 33 can be threaded through the U-shaped connecting plate 44, and the connection between the bidirectional screw 33 and the branch pipe 4 can also be achieved. Further preferably, a worm gear is coaxially arranged in the middle of the bidirectional screw 33, a driving motor 34 is arranged in the middle of the main pipe 3, and a worm gear meshing with the worm gear is coaxially arranged on the main shaft of the driving motor 34, so that the bidirectional screw 33 can be driven to rotate by the transmission structure of the worm gear, and the locking function of the worm gear can be used to prevent the bidirectional screw 33 from moving automatically, thereby further improving the position stability of the two branch pipes 4.

[0040] Preferably, Figure 1 , Figure 2 and Figure 5 As shown, a pair of rails 2 are provided in parallel, respectively located on both sides of the support assembly 1, and the opposite sides of the two rails 2 are provided with strip grooves 21 along their own tracks, and a pair of guide wheels 35 are provided at both ends of the main pipe 3, respectively. The connection line between the two guide wheels 35 at the same end of the main pipe 3 is perpendicular to the main pipe 3 and the two branch pipes 4, and the guide wheels 35 are all rolled in the strip grooves 21. This structural design can effectively improve the stability of the spray assembly when moving along the rail 2. The movement of the spray assembly can still adopt the following scheme: the main pipe 3 is connected to a certain link of an annular chain, the annular chain is laid along the track of the rail 2, and sprockets are set at the ends and arc corners of the rail 2 to support and install the annular chain, and a motor is connected to one of the sprockets, and the annular chain is driven by the motor to reciprocate along the track of the rail 2, which is used to drive the main pipe 3 to reciprocate along the track 2, thereby finally achieving the purpose of moving the spray assembly along the track 2.

[0041] Preferably, Figure 2 , Figure 3 , Figure 5 and Figure 6As shown, the outer wall of the track 2 is provided with teeth, and the length direction of the teeth is consistent with the length direction of the main pipe 3. Climbing motors 36 are provided on the outer sides of both ends of the main pipe 3. The main shaft of the climbing motor 36 is coaxially provided with an anti-skid wheel with a gear structure. The anti-skid wheel matches the teeth of the outer wall of the track 2. By driving the two anti-skid wheels to roll on the teeth of the two tracks 2 at the same time by two climbing motors 36, the spray assembly can be moved along the track 2, and it has a good anti-skid function, which helps the spray assembly to move smoothly.

[0042] Further preferably, Figure 3 and Figure 6 As shown, the climbing motor 36 is arranged on a mounting plate 361, and the mounting plate 361 is connected to the main pipeline 3 by at least two bolts 362, or is connected to a bracket arranged on the main pipeline 3. As a preferred solution, in order to avoid mutual interference between the collars, the layout between the guide wheel 35, the bidirectional screw 33 and the climbing motor 36 is more reasonable, or, in this embodiment, both ends of the main pipeline 3 are provided with a U-shaped bracket, and the two guide wheels 35 at the same end of the main pipeline 3 are respectively arranged at the intersection of the two side rods and the bottom of the bracket, and the two bolts 362 connecting the mounting plate 361 are respectively connected to the top of the two side rods of the bracket, and the bidirectional screw 33 is located between the climbing motor 36 and the main pipeline 3. The bolt 362 is provided with a pressure spring 36 3. The pressure spring 363 is located between the head of the bolt 362 and the top surface of the mounting plate 361. The pressure generated by the pressure spring 363 is used to press the anti-skid wheel against the outer wall of the track 2. The reason why this type of structure is used to install the climbing motor 36 is that when the guide wheel 35 moves to the arc transition structure position between the horizontal section and the vertical section of the track 2, the distance between the midpoint of the line connecting the two guide wheels 35 at the same end of the main pipeline 3 and the outer wall of the track 2 will increase, which will cause the anti-skid wheel to get stuck and affect the smooth movement of the spraying assembly. After the pressure spring 363 is set, the distance between the anti-skid wheel and the outer wall of the track 2 has a certain movable space to adapt to the change in the distance between the guide wheel 35 and the outer wall of the track 2 and prevent the anti-skid wheel from getting stuck.

[0043] like Figure 1 As shown, the external refrigeration layer spraying device of the energy storage cabinet also includes a spraying room, the support assembly 1, the track 2 and the spraying assembly are all arranged in the spraying room, and a pair of horizontally arranged slide rails 11 are arranged at the bottom of the spraying room, and the support assembly 1 is slidably arranged on the slide rails 11 to facilitate the transfer of the cabinet. Figure 1 , Figure 2 and Figure 5 As shown, the support assembly 1 is provided with a lifting platform 12 for placing the cabinet. When spraying the top surface of the cabinet, the distance between the top surface of the cabinet and the fixed nozzle 31 can be adjusted by controlling the lifting platform 12. The lifting platform 12 is controlled by a hydraulic cylinder or a pneumatic cylinder.

[0044] The above description is only a preferred embodiment of the present invention, and is not intended to be the only one or to limit the present invention. Those skilled in the art should understand that various changes or equivalent substitutions made to the present invention without departing from the scope of the present invention are within the scope of protection of the present invention.
