Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of distribution cabinet, especially distribution box base and distribution box assembly. BACKGROUND

[0002] Intelligence is an important direction of the development of distribution box. The traditional distribution box assembly does not consider the needs of data communication and remote monitoring. Today, in order to realize the intelligent management of the distribution box, the communication module needs to be integrated in the assembly, such as ZigBee, LoRa or Ethernet interface, etc. At the same time, there also needs to be a corresponding sensor to monitor the electrical parameters (such as voltage, current, temperature, etc.), and these sensors and communication modules need to be well compatible with other components of the distribution box, and the structure design needs to be convenient for installation and maintenance.

[0003] However, in the existing technology, there are the following deficiencies. The traditional fixing method may be to directly connect the bottom of the distribution box with the installation plane through bolts. This requires that during installation, the bolt needs to be passed through the mounting hole of the bottom of the distribution box and the corresponding hole on the installation plane, and then the nut is tightened. However, due to the heavy weight of the distribution box, multiple people need to cooperate to lift the distribution box during the installation process, and the installation and tightening operation of the bolt is carried out at the same time, which makes the installation process complicated and labor-intensive. Moreover, when installing the distribution box in a narrow space or at a high place, this traditional installation method is more inconvenient, and requires higher operation skills and physical strength of the installer.

[0004] And due to the lack of effective automatic cleaning mechanism, dust will gradually accumulate on the surface of electrical components and near the ventilation opening after entering the distribution box. With the passage of time, the dust will accumulate more and more, not only blocking the ventilation opening, further affecting heat dissipation, but also possibly causing damage to electrical components due to conductivity and other issues, such as causing short circuits, reducing insulation performance, etc. Therefore, the distribution box base and distribution box assembly are provided by the skilled person in the art to solve the problems in the above-mentioned prior art. SUMMARY

[0005] The utility model discloses a distribution box base and distribution box assembly are provided to solve the problems in the prior art. To achieve the above purpose, the utility model provides the following technical scheme: a gas cylinder is installed in the middle of the bottom of the inner side wall of the mounting base, the output end of the gas cylinder is connected to a jacking plate, lifting positioning blocks are installed near the four corner positions on the top of the jacking plate, positioning grooves are provided near the four corner positions on the top of the mounting groove, and the lifting positioning blocks can move up and down in the positioning grooves through the extension and retraction of the gas cylinder, thereby accurately jacking, positioning and fixing the distribution cabinet.

[0006] Preferably, the bottom of the two side walls of the mounting base is provided with a mounting plate, and a threaded groove is formed in the top of the mounting plate, so that the mounting base can be fixed at a predetermined position by bolts.

[0007] Preferably, a bottom dust prevention filter screen is installed in the middle of the bottom of the mounting groove, which can effectively prevent dust from entering while ensuring the heat dissipation of the bottom of the power distribution cabinet.

[0008] Preferably, a cleaning assembly is fixedly installed in the middle of the rear side wall and the middle of the two side walls of the mounting base. A double-shaft motor is installed in the middle of the inner side wall of the cleaning assembly. The two output ends of the double-shaft motor are connected to transmission rods, and the other end of the transmission rod is provided with a driving bevel gear. The front side wall of the driving bevel gear is engaged with a driven bevel gear.

[0009] Preferably, a fixed recess block is installed in the middle of the front side wall of the cleaning assembly. A screw rod is rotatably connected to the middle of the inner side wall of the fixed recess block. One end of the screw rod is connected to the middle of the front side wall of the driven bevel gear through a connecting shaft. The sliding end of the screw rod is provided with a sliding block. The middle of the two side walls of the sliding block is provided with a cleaning plate. An active slot is formed in the connection between the fixed recess block and the two side walls of the mounting base. Through the driving of the double-shaft motor, the cleaning plate can move in the active slot to clean the heat dissipation grilles on the two side walls of the power distribution cabinet.

[0010] Preferably, universal wheels are rotatably connected to the middle of the bottom of the power distribution cabinet body near the four corners, which facilitates the movement of the power distribution cabinet when it is not installed on the mounting base. Limiting grooves corresponding to the lifting positioning blocks on the mounting base are also formed in the middle of the bottom near the four corners, which are used for precise installation and positioning in cooperation with the mounting base.

[0011] Preferably, side plate heat dissipation grilles are installed in the middle of the two side walls of the power distribution cabinet body near the lower end, which are used for side heat dissipation of the power distribution cabinet and matched with the cleaning plate in the cleaning assembly of the mounting base, so as to facilitate the cleaning of dust on the grilles. A top cover heat dissipation mechanism is installed in the middle of the top, which further enhances the overall heat dissipation capacity of the power distribution cabinet.

[0012] The utility model has the following beneficial effects:

[0013] 1、In the utility model, the mounting base can be conveniently and quickly fixed at a predetermined position by the two side mounting plates and threaded grooves. At the same time, the power distribution cabinet body can be easily pushed above the mounting groove and accurately lifted and positioned by the use of the slope, the jacking plate driven by the air cylinder and the lifting positioning block, which greatly simplifies the installation process of the power distribution cabinet and reduces the installation time and labor cost.

[0014] 2、The bottom heat dissipation dust filter screen of the mounting groove bottom can effectively dissipate heat and block dust at the bottom of the power distribution cabinet, the double-shaft motor drives the transmission rod, the driving bevel gear and the driven bevel gear, and then drives the lead screw and the sliding block, so that the cleaning plate moves in the movable groove, and the side plate heat dissipation grille can be automatically cleaned. This not only ensures that the heat dissipation efficiency of the heat dissipation grille is always at a high level, but also reduces the frequency and workload of manual cleaning, and reduces the possibility of affecting the heat dissipation effect due to manual cleaning not in time or not completely.

[0015] 3、The universal wheel at the bottom of the power distribution cabinet body can freely move when the power distribution cabinet is not installed on the base, facilitating transfer and layout adjustment between different working areas, improving the mobility and adaptability of the power distribution box assembly, and being especially suitable for places where the position of the power distribution box needs to be frequently changed or temporary power supply scenes.

[0025] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0026] With reference to Figure 1 — Figure 5 , the power distribution box base and the power distribution box assembly, first, the installation position of the installation base 2 is determined, the installation base 2 is carried to the position, through the threaded groove on the installation plate 201 at the bottom of the two side walls of the installation base 2, the installation base 2 is firmly fixed on the ground or other predetermined installation plane by using appropriate bolts, at this time, the air cylinder 204 inside the installation base 2 is in the retracted state, the lifting positioning block 207 on the jacking plate 205 is located at the lower position, which does not affect the subsequent operation, the power distribution cabinet assembly 1 is pushed to the vicinity of the installation base 2, since the universal wheels 104 are installed at the bottom of the four corners of the power distribution cabinet body 101, the power distribution cabinet body 101 can be moved relatively easily, the power distribution cabinet body 101 is pushed along the ramp 203 in the middle of the front side wall of the installation base 2 to above the installation slot at the top of the installation base 2, so that the power distribution cabinet body 101 is located in the position directly above the installation slot.

[0027] The air cylinder 204 in the middle of the inner side wall at the bottom of the installation base 2 is started, the output end of the air cylinder 204 starts to expand and push the jacking plate 205 to move upward, along with the rising of the jacking plate 205, the lifting positioning blocks 207 near the four corner positions at the top of the jacking plate 205 slide upward along the corresponding positioning grooves 206 at the top of the four corners respectively, when the lifting positioning blocks 207 completely pass through the positioning grooves 206, they will be inserted into the limiting grooves corresponding to the lifting positioning blocks 207 opened near the four corner positions at the bottom of the power distribution cabinet body 101, so as to accurately jacking and positioning the power distribution cabinet body 101 on the installation base 2, completing the installation and fixation of the power distribution cabinet, at the same time, the bottom dustproof heat dissipation filter screen 202 at the bottom of the installation slot starts to play a role, which performs heat dissipation and ventilation for the bottom of the power distribution cabinet body 101, and prevents impurities such as dust from entering the inside of the power distribution cabinet from the bottom.

[0028] When the power distribution cabinet runs for a period of time, the side plate heat dissipation grille 103 on the two side walls needs to be cleaned to ensure the heat dissipation effect. At this time, the double-shaft motor 301 in the cleaning assembly 3 in the middle of the rear side wall and the middle of the two side walls is started. The two output ends of the double-shaft motor 301 drive the transmission rod 302 to rotate. The driving bevel gear 303 at the other end of the transmission rod 302 rotates, the driving bevel gear 303 meshes with the driven bevel gear 304 to drive the driven bevel gear 304 to rotate. The lead screw 306 connected to the front side wall of the driven bevel gear 304 rotates synchronously with the driven bevel gear 304 through the connecting shaft. Since the lead screw 306 is rotatably connected to the fixed recess block 305 at both ends, when the lead screw 306 rotates, the sliding block 307 sleeved on the sliding end of the lead screw 306 will move linearly along the lead screw 306. The cleaning plate 308 installed in the middle of the two side walls of the sliding block 307 will move together with the sliding block 307. Through the movable groove 309 connecting the fixed recess block 305 and the connecting position of the two side walls of the mounting base 2, the cleaning plate 308 moves back and forth in the movable groove 309. The side plate heat dissipation grille 103 on the two side walls of the power distribution cabinet body 101 is wiped and cleaned to remove dust and debris on the grille surface, ensuring that the heat dissipation channel of the side plate heat dissipation grille 103 is unobstructed, effectively improving the heat dissipation efficiency of the power distribution cabinet, and ensuring that the electrical elements inside the power distribution cabinet can operate stably in a good temperature environment.

[0029] During the entire implementation process, the power distribution box base and the power distribution box assembly realize convenient and fast installation, precise positioning, and effective heat dissipation and heat dissipation grille cleaning function through the cooperation between the components, greatly improving the practicality, reliability and maintenance convenience of the power distribution box, and meeting the use requirements of various power distribution places.

[0030] Working principle: when the power distribution cabinet assembly 1 needs to be installed, the power distribution cabinet body 101 can be pushed onto the installation groove on the top of the installation base 2 by using the slope 203 in the middle of the front side wall of the installation base 2. At this time, the air cylinder 204 is in the initial state, and the lifting positioning block 207 on the lifting plate 205 is in the lower position.

[0031] Then, cylinder 204 is activated, and the output end of cylinder 204 pushes the lifting plate 205 upward. The four lifting positioning blocks 207 on the top of the lifting plate 205 pass through the positioning slots 206 at the four corners of the top of the mounting slot. The limiting slot at the bottom of the distribution cabinet body 101 corresponds to the lifting positioning block 207. As the lifting positioning block 207 rises, the distribution cabinet body 101 is lifted and precisely positioned. At the same time, the bottom heat dissipation and dustproof filter 202 in the middle of the bottom of the mounting slot can dissipate heat from the bottom of the distribution cabinet body 101 and prevent dust from entering. The cleaning component 3 in the middle of the rear side wall and the middle of the side walls of the mounting base 2 is used to clean the side plate heat dissipation grilles 103 on both sides of the distribution cabinet body 101. After the dual-axis motor 301 in the cleaning component 3 is started, its two output ends drive the transmission rod 302 to rotate. The active bevel gear 303 at the other end of the transmission rod 302 rotates accordingly. The active bevel gear 303 meshes with the driven bevel gear 304, driving the driven bevel gear 304 to rotate.

[0032] The lead screw 306 connected to the front side wall of the driven bevel gear 304 rotates synchronously with the driven bevel gear 304 via a connecting shaft. Since both ends of the lead screw 306 are rotatably connected to the fixed recess 305, when the lead screw 306 rotates, the slider 307 sleeved on the sliding end of the lead screw 306 will move along the lead screw 306. The cleaning plate 308 installed in the middle of the two side walls of the slider 307 will move with the slider 307. Through the movable groove 309 at the connection between the fixed recess 305 and the two side walls of the mounting base 2, the cleaning plate 308 can move in the movable groove 309 and clean the side plate heat dissipation grille 103, removing dust and other debris from the grille to ensure heat dissipation effect. At the same time, the cleaning component 3 can periodically clean the side plate heat dissipation grille 103 to prevent dust accumulation from affecting the heat dissipation effect, and the top cover heat dissipation mechanism 102 further ensures the heat dissipation effect.

[0033] The bottom center of the power distribution cabinet body 101 is rotatably connected to four corners. When not installed on the mounting base 2, the power distribution cabinet body 101 can be easily moved using the casters 104, allowing it to be moved between different positions for easy transportation and temporary position adjustment.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
