Description

Technical Field

[0001] The utility model relates to the technical field of anti-collision of distribution cabinets, and specifically relates to an anti-collision distribution cabinet. Background Art

[0002] Distribution cabinets for power distribution, protecting electrical equipment, power monitoring and control can be used indoors and outdoors according to requirements, and various electrical components such as circuit breakers, contactors, relays, etc. are installed inside. The above components are relatively sensitive to collisions. In addition, when the distribution cabinet is installed outdoors, once it is strongly impacted, it may cause misalignment, loosening or even damage of the components. For example, the operating mechanism of the circuit breaker may be deformed due to impact, affecting its normal opening and closing functions; the contacts of the contactor may be poorly contacted due to vibration, resulting in circuit failures.

[0003] In order to solve the situation where various electrical components of the distribution cabinet are misaligned, loosened or even damaged due to collision, there are different types of anti-collision solutions in the publicly disclosed technologies of the distribution cabinet. For example, a high-strength anti-collision distribution cabinet disclosed in a Chinese patent with the publication number CN11118103A includes a housing assembly, a support assembly, a horizontal shock-absorbing assembly, and a vertical shock-absorbing assembly. The housing assembly is located on the outer side of the whole device. The bottom of the housing assembly is provided with a support assembly. A horizontal shock-absorbing assembly is arranged inside the housing assembly, and a vertical shock-absorbing assembly is arranged on one side of the horizontal shock-absorbing assembly. The distribution cabinet provided by the above patent is scientific and reasonable, safe and convenient to use. Based on spring shock absorption, it uses the method of slowly increasing the friction force between the friction shock-absorbing block and the horizontal shock-absorbing connecting column to avoid the secondary damage phenomenon caused by the spring elastic force to the distribution cabinet, and prevents the influence of the spring-induced jitter on the equipment during shock absorption. Moreover, the vertical shock-absorbing assembly is installed on the side of the inner installation cabinet, and the bottom support spring mainly plays a supporting role, and can also effectively avoid the secondary damage caused by the spring jitter to the distribution cabinet while providing anti-collision shock absorption.

[0004] It can be seen from the technology disclosed in the above patent that it mainly installs shock-absorbing components inside the housing, and offsets the impact force through the action of the shock-absorbing components. Although the method provided by the above patent can offset the impact force and avoid damage to electrical components, its protection measures can only be activated after the external force contacts the housing, that is, only when the distribution cabinet is directly impacted can the shock-absorbing components protect the electrical components inside. The final result is that the housing of the distribution cabinet is damaged, the anti-collision effect is not satisfactory, and it takes time to repair the distribution cabinet, affecting the operation of the distribution cabinet.

[0035] The following will be further described in conjunction with the accompanying drawings and specific embodiments:

[0036] Embodiment 1

[0037] In order to effectively achieve the anti-collision of the power distribution cabinet and change the current situation where the anti-collision function can only be activated after the power distribution cabinet is directly impacted internally, in this embodiment, an anti-collision component is provided on the outer side of the existing power distribution cabinet body. This anti-collision component effectively and fully protects the power distribution cabinet, that is, when there is an external object out of control, it first impacts the anti-collision component and then is intercepted, avoiding its direct impact on the cabinet body and causing damage to the electrical components inside the cabinet.

[0038] Such as Figure 1 , Figure 2 , Figure 3As shown, the reason for providing a distribution cabinet with anti-collision function is that there are various electrical components installed in the cabinet body of the existing distribution cabinet. Here is a brief introduction to the existing distribution cabinet. The distribution cabinet includes a housing, a circuit breaker, a contactor, a relay, a fuse, an instrument transformer, etc. There are multiple chambers separated inside the housing, such as an incoming line compartment, an outgoing line compartment, a busbar compartment, and a control compartment. The circuit breaker is one of the most important electrical components in the distribution cabinet, which is used to automatically cut off the circuit in case of faults such as overload and short circuit in the circuit to protect the safety of equipment and personnel. The contactor is used to control the on-off of the circuit to realize the start-stop control of loads such as motors. The relay is used to realize functions such as logic control and signal conversion. The fuse is used to cut off the circuit by fusing itself in case of short circuit or overload in the circuit to play a protective role. The instrument transformer is used to measure parameters such as current and voltage in the circuit, etc. In order to make the distribution cabinet have anti-collision function and protect the above-mentioned various electrical components, therefore, an anti-collision component is installed under the existing distribution cabinet to form a new distribution cabinet. In the following text, the existing distribution cabinet is called cabinet body 1.

[0039] As Figure 4 shown, in order to achieve the anti-collision of the distribution cabinet, the anti-collision component includes an inner frame 3, an outer frame 4, multiple connecting plates 6, multiple anti-collision bars 2, and multiple buried bars 5. The inner frame 3 is set in a rectangular structure with holes in the middle, and the length and width of the inner frame 3 are the same as those of the bottom of the cabinet body 1. Therefore, the inner frame 3 is installed under the cabinet body 1 by bolt connection and directly contacts the ground. Under the action of the inner frame 3, the cabinet body 1 can be stably installed relative to the ground. The outer frame 4 is set in a rectangular structure and is arranged outside the inner frame 3. In addition, multiple connecting plates 6 are distributed between the outer frame 4 and the inner frame 3, and under their action, the relative positions of the inner frame 3 and the outer frame 4 are restricted, which facilitates the realization of the anti-collision function of the cabinet body 1. Multiple anti-collision bars 2 are distributed and installed above the outer frame 4, that is, on the outside of the cabinet body 1. Therefore, when an external object moves rapidly towards the cabinet body 1 out of control, it first contacts the anti-collision bars 2, and the external object is stopped by the anti-collision bars 2, thereby realizing the protection of the cabinet body 1. In order to enhance the ability of the anti-collision bars 2 to resist the impact of external objects, multiple buried bars 5 are distributed and installed under the inner frame 3 and the outer frame 4 and inserted into the ground, and their action enhances the stability of the inner frame 3 and the outer frame 4. In order to facilitate the staff to open the cabinet door and minimize the area occupied by the anti-collision component as much as possible, the front space formed by the outer frame 4 and the cabinet body 1 is larger than the rear space. In this case, the anti-collision bars 2 located at the rear of the cabinet body 1 are close to the cabinet body 1, while the anti-collision bars 2 at the front are installed relatively far from the cabinet body 1 to avoid affecting the opening of the cabinet door due to the presence of the anti-collision bars 2.

[0040] As Figure 5 、 Figure 6 、 Figure 7As shown in the figure, in order to achieve the stable connection between the inner frame 3 and the outer frame 4, a plurality of slots 32 are provided on the outer side surface of the inner frame 3, and a plurality of end plates 42 are provided on the inner side surface of the outer frame 4. The end plates 42 are installed in the upper middle part of the outer frame 4. One end of the connecting plate 6 is provided with a plug plate 61, and the other end is provided with an end groove 62. The upper side surface and the end surface of the end groove 62 are both open. Therefore, when the connecting plate 6 is installed between the inner frame 3 and the outer frame 4, the plug plate 61 is inserted into the slot 32 through bolt connection, and the end plate 42 is installed in the end groove 62 through bolt connection. Under the action of the connecting plate 6, the stable connection between the inner frame 3 and the outer frame 4 is achieved. Specifically, when it is necessary to connect the inner frame 3 and the outer frame 4, first install the connecting plate 6 on the outer side of the inner frame 3, and then move the outer frame 4 downward from top to bottom so that the end plate 42 is installed in the end groove 62.

[0041] As Figure 5 , Figure 8 shown, in order to achieve the stable connection between the buried rod 5 and the inner frame 3 and the outer frame 4, the buried rod 5 is set as a T-shaped structure, and a plurality of counterbores 31 are provided on the upper side surfaces of the inner frame 3 and the outer frame 4. Therefore, after the inner frame 3 and the outer frame 4 are placed on the ground, the buried rod 5 passing through the counterbores 31 is hammered into the ground by means of hammering, and the end protruding from the ground is exactly located in the counterbores 31. By using the structural characteristics of the counterbores 31 and the top of the buried rod 5, the connection between the buried rod 5 and the inner frame 3 and the outer frame 4 is achieved.

[0042] As Figure 8 , Figure 9 , Figure 10 , Figure 11 shown, in order to increase the resistance of the buried rod 5 to rise relative to the ground, a cavity with an upward opening is provided on the inner side of the buried rod 5. A plurality of inclined holes 53 are provided on the side wall of the cavity, and a rotating shaft 51, a lifting disc 55 and a plurality of inverted plates 52 are provided on the inner side. The plurality of inverted plates 52 are evenly distributed on the outer side of the lifting disc 55 and penetrate through the inclined holes 53. A connecting groove 56 is provided on the outer side of the lifting disc 55, and the size of the connecting groove 56 is larger than the size of the inverted plate 52. Therefore, when the inverted plate 52 penetrates through the inclined hole 53, its bottom is located in the connecting groove 56, and the inverted plate 52 can be protruded and inserted into the soil by controlling the lifting of the lifting disc 55. In order to be able to control the lifting of the lifting disc 55, a threaded hole 57 is provided on the lifting disc 55, and a thread 58 is provided on the rotating shaft 51. The lifting disc 55 is threadedly sleeved at the thread 58 of the rotating shaft 51. Therefore, the lifting of the lifting disc 55 can be controlled by rotating the rotating shaft 51. In addition, a convex column is provided on the side wall of the cavity of the buried rod 5, and the convex column is arranged along the height direction of the buried rod 5. An annular top plate 54 is sleeved on the top of the rotating shaft 51. Grooves are provided on the outer side surfaces of the annular top plate 54 and the lifting disc 55, and the grooves are also arranged along the height direction of the buried rod 5, and the convex column is located in the groove. At the same time, the annular top plate 54 is fixedly connected to the buried rod 5. With the cooperation of the convex column and the groove, the rotation of the lifting disc 55 is restricted, and under the action of the annular top plate 54, the rotating shaft 51 is stably installed relative to the buried rod 5.

[0043] Embodiment 2

[0044] As Figure 6 、 Figure 12 、 Figure 13 、 Figure 14 shown, on the basis of Embodiment 1, in order to be able to disassemble and assemble the anti-collision bar 2 according to requirements, a plurality of limiting tubes 41 are arranged above the outer frame 4. The outer side surface of the limiting tube 41 is set as a frustum structure. In addition, the limiting tube 41 is fixedly connected to the outer frame 4 and is aligned with the counterbore 31, and at the same time, the inner diameter is larger than the diameter of the counterbore 31, which provides convenience for the installation of the buried rod 5. An external thread tube 59 is fixedly arranged at the top of the buried rod 5. The inner diameter of the external thread tube 59 is larger than or equal to the diameter of the cavity of the buried rod 5 to avoid affecting the installation of the rotating shaft 51 and the lifting disc 55 due to the existence of the external thread tube 59. The bottom of the anti-collision bar 2 extends into the limiting tube 41, and an internal thread groove 21 is arranged on the bottom surface. The external thread tube 59 is threadedly inserted into the internal thread groove 21. Therefore, the strength of the anti-collision bar 2 is enhanced under the cooperation of the limiting tube 41 and the buried rod 5, and it is convenient for the staff to disassemble the anti-collision bar 2 according to requirements.

[0045] The above is only the preferred embodiment of the present invention and is not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications.
