Abstract
Description
Technical Field
[0001] The present application relates to the technical field of electrical equipment, and in particular to an incoming line cabinet. Background Art
[0002] The incoming line cabinet is a switch cabinet that introduces power from the outside, also called a power receiving cabinet. It is a device used to receive power from the power grid (from the incoming line to the busbar). It is generally equipped with circuit breakers, CTs, PTs, isolating switches and other components. Taking the 6kV incoming line cabinet as an example, it generally introduces 6kV power from the power supply network, and the 6kV power is sent to the 6kV busbar through the switch cabinet.
[0003] At present, the internal space of some commonly used central trolley-type incoming cabinets consists of four parts, namely the busbar room, circuit breaker trolley room, cable room and instrument room. Each functional room and the unit functional room of each circuit are separated by grounded steel plates without interfering with each other. The busbar room is located in the incoming cabinet near its back panel. The front side of the incoming cabinet is the instrument room and trolley room from top to bottom. The bottom of the incoming cabinet is all cable room along the cabinet depth direction, and the components in the cable room are mostly installed in the position of the incoming cabinet near the back panel. Therefore, part of the cable room below the trolley room is mostly vacant.
[0004] The transfer cart used for handcarts is a commonly used tool for central electrical cabinets. Since the handcart room is at a certain height from the ground, when the technician needs to inspect and maintain some electrical components on the handcart in the incoming cabinet, the handcart will be moved to a position close to the cabinet door through the screw mechanism first, and then the transfer cart will be moved from the warehouse or tool room, and then the height of the top of the transfer cart will be adjusted to be close to the height of the bottom of the handcart, and then the handcart will be dragged from the incoming cabinet to the transfer cart, so that the transfer cart can be used to transfer the handcart between the inside and outside of the cabinet, so that the technician can inspect and maintain the parts on the handcart or the parts in the handcart room. However, the storage point of the transfer cart is usually at a certain distance from the incoming cabinet, and the technician will spend a certain amount of time in the process of moving the transfer cart to the incoming cabinet, which will affect the efficiency of the inspection and maintenance of related parts, and the temporary storage of the transfer cart will also occupy a certain production site, which will reduce the space available to the production enterprise. Utility Model Content
[0005] The present application provides an incoming line cabinet, which can effectively utilize part of the space in the cable room at the lower side of the incoming line cabinet to store equipment used by the trolleys in the trolley room. This can not only effectively solve the space problem of the production site, but also improve the efficiency of repairing and maintaining the parts on the trolley or in the trolley room.
[0006] The above-mentioned purpose of the present application is achieved through the following technical solutions:
[0007] An incoming line cabinet comprises an incoming line cabinet body, an outer protection box is provided on the top of a cable chamber at the lower side of the incoming line cabinet body, the outer protection box is slidably connected to the inner side wall of the cable chamber via a slide rail, and the sliding direction is perpendicular to the plane where the back plate of the incoming line cabinet body is located;
[0008] An adjustable platform is provided inside the outer protection box, and the adjustable platform can adjust its height in the vertical direction;
[0009] A plurality of folding legs are provided on the lower side of the outer protection box. When the outer protection box is located in the cable room of the incoming line cabinet body, the folding legs are in a stored state on the lower side of the outer protection box; when the outer protection box is located outside the incoming line cabinet body, the folding legs can be adjusted to an unfolded state to support the outer protection box on the ground.
[0010] Furthermore, the number of the folding legs is four, and the tops of the four folding legs are hinged to the lower side of the outer protective box.
[0011] Furthermore, the connection positions of two of the folding legs and the outer protective box are respectively located at two corners of one end of the bottom of the outer protective box, and there is a distance between the connection positions of the other two folding legs and the outer protective box and the other end of the bottom of the outer protective box.
[0012] Furthermore, the swinging direction of the four folding legs below the outer protection box is along the width direction of the incoming line cabinet body, and a limit hole is provided on the folding legs. When the folding legs are in a horizontal state below the outer protection box, the opening end of the limit hole faces upward.
[0013] Furthermore, two columns are provided on one side of the two folding legs at each end of the lower side of the outer protection box; the upper end of the column is fixedly connected to the lower side of the outer protection box, and the lower end of the column is rotatably connected to one end of the baffle.
[0014] Furthermore, the adjustable platform is a hand-cranked lifting platform.
[0015] Furthermore, a downwardly bent handle is provided at one end of the back plate of the outer protection box away from the incoming cabinet body.
[0016] In summary, the present application includes at least one of the following beneficial technical effects:
[0017] When it is necessary to transfer the trolley in the trolley room of the incoming cabinet body, the technician opens the cable room under the incoming cabinet body, slides the outer protection box out from the upper space of the cable room, and then adjusts the folding legs under it to the unfolded state. At this time, the folding legs can support the outer protection box on the ground, and then adjust the height of the adjustable platform in the vertical direction until the top height of the adjustable platform is consistent with the lower height of the trolley. The trolley can be moved to the adjustable platform, and then the transfer equipment is used to transfer the trolley. After the subsequent maintenance of the parts on the trolley or in the trolley room is completed, the transfer equipment can be used to put the trolley back into the trolley room, and then the folding legs under the outer protection box are retracted, and the adjustable platform is also retracted into the outer protection box. At this time, the outer protection box can be stored in the top of the cable room again. The present application effectively utilizes the excess space in the cable room to place the transfer equipment of the trolley, so that the transfer equipment of the trolley does not need to occupy other production sites outside the incoming cabinet body, thereby increasing the available space on the production site of the production enterprise. And the trolley transfer equipment is arranged in the incoming line cabinet body, so when the trolley needs to be transferred, the time of moving the transfer equipment to the front of the trolley can be greatly reduced, thereby effectively improving the inspection and maintenance efficiency of the trolley or the parts in the trolley room.

[0024] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application is clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work also fall within the scope of protection of the present application.
[0025] like Figure 1-Figure 3 As shown, a line incoming cabinet disclosed in the present application comprises a line incoming cabinet body 1, an outer protection box 3 is provided on the top of a cable chamber 2 at the lower side of the line incoming cabinet body 1, the outer protection box 3 is slidably connected to the inner side wall of the cable chamber 2 via a slide rail 4, and the sliding direction is perpendicular to the plane where the back plate of the line incoming cabinet body 1 is located; an adjustable platform 5 is provided in the outer protection box 3, and the adjustable platform 5 can adjust its own height in the vertical direction;
[0026] A plurality of folding legs 6 are provided on the lower side of the outer protection box 3. When the outer protection box 3 is located in the cable chamber 2 of the incoming line cabinet body 1, the folding legs 6 are in a stored state at the lower side of the outer protection box 3; when the outer protection box 3 is located outside the incoming line cabinet body 1, the folding legs 6 can be adjusted to an unfolded state to support the outer protection box 3 on the ground.
[0027] In the above embodiments, the outer protection box 3 is arranged in the upper position of the cable chamber 2 in the main body 1 of the incoming cabinet of the present application, so that the free space above the cable chamber 2 can be utilized, and after the outer protection box 3 is pulled out of the main body of the incoming cabinet, the adjustable platform 5 in the outer protection box 3 moves a relatively small distance when it is adjusted to the lower side of the trolley in the vertical direction, which can improve the efficiency of the height adjustment of the adjustable platform 5. The slide rail 4 with a sliding connection effect between the outer protection box 3 and the inner side wall of the cable chamber 2 can be a drawer slide rail 4, so that the outer protection box 3 has a small resistance during the pulling process and is very convenient to operate.
[0028] When the outer protection box 3 of the present application is located in the cable chamber 2 in the incoming cabinet body 1, the multiple folding legs 6 are in a horizontal state at the bottom of the outer protection box 3, so that the folding legs 6 will not occupy too much space in the cable chamber 2. And a universal wheel with a self-locking function is installed at the bottom of each folding leg 6, so that it is convenient to move the outer protection box 3 and use the adjustable platform 5 thereon to achieve the transportation effect of the opponent's car.
[0029] When the trolley needs to be transferred, the technician can pull out the outer protection box 3 from the incoming cabinet body 1, and in the process of pulling out the outer protection box 3, timely adjust the folding legs 6 below it so that the folding legs 6 located outside the incoming cabinet body 1 can be unfolded in time. After the outer protection box 3 is completely pulled out of the incoming cabinet body 1, all the folding legs 6 are in the unfolded state, that is, all the folding legs 6 are perpendicular to the ground. At this time, the outer protection box 3 can be supported at a certain height above the ground by multiple folding legs 6. Then the technician adjusts the adjustable platform 5 so that the upper side of the adjustable platform 5 is flush with the lower side of the trolley, so that it will be smoother when the trolley is moved to the adjustable platform 5. After moving the trolley to the adjustable platform 5, the technician can start to transfer the trolley, and then inspect and maintain the corresponding parts on the trolley or in the trolley room. After the inspection and maintenance work is completed, the trolley can be sent back to the trolley room of the incoming cabinet body 1 through the universal wheels on the folding legs 6. Then the technician can reset the adjustable platform 5 and the folding legs 6 and put the outer protection box 3 back into the cable room 2.
[0030] Since the present application effectively utilizes the extra space in the cable room 2 to place the transfer equipment of the trolley (equipment composed of components such as the outer protection box 3, folding legs 6 and adjustable platform 5), the transfer equipment of the trolley does not need to occupy other production sites outside the incoming cabinet body 1. Compared with the prior art that separately sets up space for storing transfer equipment in other production areas outside the incoming cabinet body 1, the present application effectively increases the available space of the production enterprise at the production site. And the trolley transfer equipment is set in the incoming cabinet body 1, so that when the trolley needs to be transferred, the time to move the transfer equipment to the front of the trolley can be greatly reduced, thereby effectively improving the inspection and maintenance efficiency of the trolley or parts in the trolley room.
[0031] Furthermore, if Figure 2-Figure 4 As shown, there are four folding legs 6 , and the tops of the four folding legs 6 are hinged to the lower side of the outer protective box 3 .
[0032] In the above embodiments, the four folding legs 6 of the present application are hinged to the lower side of the outer protective box 3, so that no matter when the outer protective box 3 is in use or stored, the folding legs 6 can be quickly unfolded or folded back to the lower side of the outer protective box 3 as needed.
[0033] Furthermore, if Figure 2 and Figure 3 As shown, the connection positions of two folding legs 6 and the outer protective box 3 are respectively located at two corners at one end of the bottom of the outer protective box 3, and there is a distance between the connection positions of the other two folding legs 6 and the outer protective box 3 and the other end of the bottom of the outer protective box 3.
[0034] In the above embodiment, the four folding legs 6 of the present application are arranged in the above manner. When one end of the outer protection box 3 close to the door of the incoming cabinet body 1 is pulled out of the cable chamber 2, the folding legs 6 at the two corners below the end are also located outside the cabinet body. At this time, the technician can open the two folding legs 6 in time, thereby providing timely support to the suspended part of the outer protection box 3 located outside the incoming cabinet body 1 through the ground. As the outer protection box 3 continues to be pulled outward, one end of it is supported on the ground by two folding legs 6, and the other end is still connected to the cable chamber 2 through the slide rail 4. The other two folding legs 6 that have not been opened in the present application are at a certain distance from one end of the back panel of the outer protection box 3 close to the incoming cabinet body 1. In this way, before the outer protection box 3 is completely separated from the slide rail 4, the technician has enough reaction time to unfold the remaining two folding legs 6, and use the four folding legs 6 to provide stable support for the outer protection box 3.
[0035] The two folding legs 6 at each end of the outer protection box 3 of the present application are offset to a certain extent, so that the two folding legs 6 will not interfere with each other during the folding and unfolding process. In addition, a limit stopper is provided on the outside of the hinge point between the folding legs 6 and the outer protection box 3, or the folding legs 6 and the outer protection box 3 are connected by a 90-degree hinge, so that during the unfolding process of the folding legs 6, the folding rotation angle can be prevented from exceeding 90 degrees to affect the supporting effect of the outer protection box 3.
[0036] Furthermore, if Figure 2 and Figure 3 As shown, the swinging direction of the four folding legs 6 below the outer protection box 3 is along the width direction of the incoming cabinet body 1, and a limit hole 7 is provided on the folding legs 6. When the folding legs 6 are in a horizontal state below the outer protection box 3, the opening end of the limit hole 7 faces upward.
[0037] In the above embodiment, after the folding legs 6 of the present application are unfolded, the limit holes 7 on the two folding legs 6 at the same end of the bottom of the outer protection box 3 will be at the same height, and the two limit holes 7 are both facing the middle position of the space below the outer protection box 3. Figure 4As shown, the technician can limit the two unfolded folding legs 6 at the same end below the external protection box 3 through the threaded telescopic rod 11, so that the two unfolded folding legs 6 will not shake during use. The structure and working principle of the threaded telescopic rod 11 are similar to the structure and working principle of the punch-free clothes drying rod in the prior art. The threaded telescopic rod 11 is composed of two pipe sections, one end of which is inserted into the other pipe section and the two are threadedly connected. The technician changes the length of one pipe section in the other pipe section by twisting it, so that the overall length of the two pipe sections can be changed. When it is necessary to limit the two folding legs 6, the technician first inserts one end of one of the pipe sections into the limiting plug hole 7 of one of the folding legs 6, and then adjusts the total length of the two pipe sections until one end of the other pipe section is inserted into the other folding leg 6.
[0038] Furthermore, if Figure 2 and Figure 3 As shown, two columns 8 are provided on one side of the two folding legs 6 at each end of the lower side of the outer protection box 3; the upper end of the column 8 is fixedly connected to the lower side of the outer protection box 3, and the lower end of the column 8 is rotatably connected to one end of the baffle 9.
[0039] In the above embodiment, when the folding legs 6 on the lower side of the outer protective box 3 are in a horizontal state, the technician rotates the baffle 9 under the column 8 to rotate it to the bottom of the two folding legs 6 on the same side, so that the baffle 9 can limit the folded folding legs 6 to prevent the folded folding legs 6 from accidentally opening in the incoming cabinet body 1.
[0040] Furthermore, if Figure 3 and Figure 4 As shown, the adjustable platform 5 is a hand-cranked lifting platform.
[0041] In the above embodiment, the technician can adjust the height of the hand-cranked lifting platform by turning the crank at the end of the hand-cranked lifting platform, and after the height is adjusted and the crank is released, the hand-cranked lifting platform also has a self-locking function, which can improve the stability of the transfer process of the trolley. The hand-cranked lifting platform is a prior art, and the specific working principle will not be described in detail here.
[0042] Furthermore, if Figure 3 and Figure 4 As shown, a downwardly bent handle 10 is provided at one end of the back plate of the outer protection box 3 away from the incoming cabinet body 1.
[0043] In the above embodiments, the handle 10 provided on the outer protection box 3 facilitates the technician to quickly pull out the outer protection box 3 and its accessory components from the cable chamber 2 .
[0044] The implementation principle of this embodiment is: when the outer protection box 3 of the present application is located in the cable chamber 2 in the incoming cabinet body 1, the multiple folding legs 6 are in a horizontal state at the bottom of the outer protection box 3.
[0045] When a transfer trolley is needed, the technician can pull out the outer protection box 3 from the incoming cabinet body 1, and in the process of pulling out the outer protection box 3, timely adjust the folding legs 6 below it, so that the folding legs 6 located outside the incoming cabinet body 1 can be unfolded in time and be in a vertical state. After the outer protection box 3 is completely pulled out of the incoming cabinet body 1, all the folding legs 6 are perpendicular to the ground. In order to increase the stability of the folding legs 6, a threaded telescopic rod 11 can be installed between the two folding legs 6 at the same end, so that the folding legs 6 are always kept in a vertical state when in use.
[0046] At this time, the outer protection box 3 can be stably supported at a certain height above the ground by multiple folding legs 6. Then the technician screws the crank at the end of the adjustable platform 5 so that the upper side of the adjustable platform 5 is flush with the lower side of the trolley, so that it will be smoother when the trolley is moved to the adjustable platform 5. After moving the trolley to the adjustable platform 5, the technician can start to transfer the trolley, and then inspect and maintain the corresponding parts on the trolley or in the trolley room. After completing the inspection and maintenance work, the trolley can be sent back to the trolley room of the incoming cabinet body 1 through the universal wheels on the folding legs 6, and then the technician can reset the adjustable platform 5 and the folding legs 6 and put the outer protection box 3 back into the cable room 2.
[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
