Description

Technical Field

[0001] This utility model relates to the technical field of mining power supply equipment, and in particular to a mining explosion-proof and intrinsically safe DC regulated power supply. Background Technology

[0002] Mining explosion-proof and intrinsically safe DC regulated power supplies are special power supply equipment designed specifically for environments with explosion risks, such as coal mines. They not only need to meet the performance requirements of ordinary power supplies, such as providing stable voltage output, but also need to have explosion-proof and intrinsically safe characteristics to ensure safety in flammable and explosive environments.

[0003] The existing announcement number CN217445239U, entitled "A Mining Explosion-proof and Intrinsically Safe DC Voltage Regulator," includes an explosion-proof housing, an explosion-proof cover on the top of the housing, an outer shock-absorbing component on the bottom outer side of the housing, and an inner shock-absorbing component on the bottom inner side of the housing. The outer shock-absorbing component includes a shock-absorbing base, with the explosion-proof housing placed inside the base. The shock-absorbing base contains a first shock-absorbing airbag, and the outer side of the housing has a buffer groove with a buffer pad on its inner side. The buffer groove matches the first shock-absorbing airbag. The inner shock-absorbing component includes a second shock-absorbing airbag. This invention, by setting up an inner and outer two-layer shock-absorbing structure, can effectively prevent the internal power supply body from being damaged by external impacts.

[0004] However, the explosion-proof enclosure and top plate of the aforementioned intrinsically safe and explosion-proof DC power supply for mining are fixed together by multiple bolts. During daily maintenance and use, it is necessary to disassemble and reassemble each of the multiple bolts on the explosion-proof enclosure and top plate. The disassembly and reassembly of multiple bolts is cumbersome and affects the convenience of maintenance and disassembly of the explosion-proof enclosure and top plate of the intrinsically safe and explosion-proof DC power supply for mining. Utility Model Content

[0005] This invention solves the problems in related technologies and proposes a mine-use explosion-proof and intrinsically safe DC regulated power supply.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: a mining explosion-proof and intrinsically safe DC voltage regulator, including an explosion-proof shell and a top plate. The top surface of the explosion-proof shell is open, and the top plate is horizontally arranged above the explosion-proof shell. An isolation slot is horizontally fixed on the top surface of the explosion-proof shell, and an isolation frame is horizontally fixed on the bottom surface of the top plate. The isolation frame on the top plate is assembled and inserted with the isolation slot on the top surface of the explosion-proof shell. Pressure frames are vertically fixed on the top of the vertical ends on both sides of the explosion-proof shell, and reinforcing screws are vertically threaded through the top surface of the pressure frames. Pressure columns are vertically fixed on both sides of the top surface of the top plate, and the bottom end of the reinforcing screw presses against the top surface of the pressure column.

[0007] As a preferred embodiment, two brackets are vertically and symmetrically inserted on the outside of the explosion-proof enclosure, and the bottom surfaces of the two brackets are fixed to the bottom surface of the explosion-proof enclosure.

[0008] As a preferred embodiment, multiple mounting bolts are vertically threaded through the bottom surface of the bracket, and an anchoring hole is horizontally opened through the upper part of the vertical end face of the bracket.

[0009] As a preferred embodiment, both sides of the top plate are vertically fixed with hole seats, and anchor rods are horizontally slidably inserted through the hole seats. The ends of the anchor rods are inserted into the anchoring holes of the bracket. Both sides of the top plate are horizontally fixed with guide frames, and the guide frames are inserted into the vertical ends of the bracket.

[0010] As a preferred embodiment, a compression spring is horizontally sleeved on the outside of the anchor rod, and the two ends of the compression spring are fixed to the hole seat and the end of the anchor rod, respectively.

[0011] As a preferred option, an assembly frame is vertically fixed on the top surface of the explosion-proof enclosure, and an assembly slot is vertically provided on the inner wall of the top plate, with the assembly slot and the assembly frame being slidably inserted into each other.

[0012] As a preferred option, assembly joints are fixedly connected to both vertical end faces of the explosion-proof enclosure.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, the top plate is set at the opening on the top surface of the explosion-proof enclosure. The isolation frame strip on the bottom surface of the top plate and the isolation slot on the top surface of the explosion-proof enclosure are assembled and inserted. Then, the vertical threads on the top pressure frame on both sides of the vertical end face of the explosion-proof enclosure are rotated to install the reinforcing screws. The rotating reinforcing screws move vertically downward and press against the top surface of the pressure column of the top plate, thereby ensuring the assembly stability of the top plate and the explosion-proof enclosure. At the same time, the pressing of the reinforcing screws ensures the assembly of the top plate and the explosion-proof enclosure, which facilitates the quick disassembly and assembly of the top plate and the explosion-proof enclosure in the later stage, and improves the convenience of maintenance and disassembly of the explosion-proof enclosure and top plate of the intrinsically safe DC voltage regulator for mining.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0017] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0018] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0019] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0020] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0021] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0022] like Figures 1 to 5As shown, a mine-use explosion-proof and intrinsically safe DC regulated power supply includes an explosion-proof housing 1 and a top plate 2. The top surface of the explosion-proof housing 1 is open, and the top plate 2 is horizontally positioned above the explosion-proof housing 1. An isolation slot 15 is horizontally fixed on the top surface of the explosion-proof housing 1, and an isolation frame strip 21 is horizontally fixed on the bottom surface of the top plate 2. The isolation frame strip 21 on the top plate 2 is assembled and inserted into the isolation slot 15 on the top surface of the explosion-proof housing 1. Pressure frames 17 are vertically fixed at the top of the vertical ends on both sides of the explosion-proof housing 1, and reinforcing screws 18 are vertically threaded through the top surface of the pressure frames 17. Pressure columns 26 are vertically fixed on both sides of the top surface of the top plate 2, and the bottom ends of the reinforcing screws 18 press against the top surface of the pressure columns 26. A reinforcing screw 18 is threaded through the top surface of the vertical ends on both sides of the explosion-proof housing 1. The assembly joint 16 is fixed. During use, the top plate 2 is set at the opening on the top surface of the explosion-proof housing 1. The isolation frame strip 21 on the bottom surface of the top plate 2 and the isolation slot 15 on the top surface of the explosion-proof housing 1 are assembled and inserted. Then, the vertical threads on the top pressure frame 17 on both sides of the vertical end face of the explosion-proof housing 1 are rotated to install the reinforcing screw 18. The rotating reinforcing screw 18 moves vertically downward and presses against the top surface of the pressure column 26 of the top plate 2, thereby ensuring the assembly stability of the top plate 2 and the explosion-proof housing 1. At the same time, the reinforcing screw 18 is used to press and ensure the assembly of the top plate 2 and the explosion-proof housing 1, which facilitates the quick disassembly and assembly of the top plate 2 and the explosion-proof housing 1 in the later stage, and improves the convenience of maintenance and disassembly of the explosion-proof housing and top plate of the intrinsically safe DC voltage regulator for mining.

[0023] In one embodiment, such as Figure 2 and 3 As shown, two brackets 11 are vertically and symmetrically inserted on the outside of the explosion-proof enclosure 1, and the bottom surfaces of the two brackets 11 are fixed to the bottom surface of the explosion-proof enclosure 1. Multiple mounting bolts 13 are vertically threaded through the bottom surface of the brackets 11, and an anchoring hole 12 is horizontally opened through the upper part of the vertical end face of the brackets 11. In use, the two brackets 11 vertically fixed on the outside of the explosion-proof enclosure 1 are fixed by multiple mounting bolts 13 to maintain the stability of the explosion-proof enclosure 1. Then, the anchoring hole 12 opened through the top of the vertical end face of the brackets 11 facilitates the stability of the subsequent assembly of the explosion-proof enclosure 1 and the top plate 2.

[0024] In one embodiment, such as Figure 3 and 5As shown, both sides of the top plate 2 are vertically fixed with hole seats 22, and anchor rods 23 are horizontally slidably inserted through the hole seats 22. The ends of the anchor rods 23 are inserted into the anchoring holes 12 of the bracket 11. Both sides of the top plate 2 are horizontally fixed with guide frames 24, and the guide frames 24 are inserted into the vertical ends of the bracket 11. A compression spring 25 is horizontally sleeved on the outside of the anchor rods 23, and the two ends of the compression spring 25 are respectively fixed to the hole seats 22 and the ends of the anchor rods 23. In order to anchor and ensure the assembly stability of the explosion-proof shell 1 and the top plate 2, the anchor rods 23 on the hole seats 22 are pulled to deform the compression springs 25. Then, the brackets 11 on the explosion-proof shell 1 and the frames 24 on the top plate 2 are slidably inserted. When the anchor rods 23 are released, they are pushed into the anchoring holes 12 of the brackets 11 under the deformation force of the compression springs 25. This anchoring ensures the assembly stability of the explosion-proof shell 1 and the top plate 2.

[0025] In one embodiment, such as Figure 4 and 5 As shown, an assembly frame 14 is vertically fixed on the top surface of the explosion-proof enclosure 1, and an assembly slot 27 is vertically provided on the inner wall of the top plate 2. The assembly slot 27 and the assembly frame 14 are slidably inserted into each other. When the explosion-proof enclosure 1 and the top plate 2 are assembled in use, the assembly slot 27 and the assembly frame 14 are slidably inserted into each other, which limits the stability of the assembly of the explosion-proof enclosure 1 and the top plate 2.

[0026] In this embodiment, the top plate 2 is placed at the opening on the top surface of the explosion-proof enclosure 1. The isolation frame strip 21 on the bottom surface of the top plate 2 and the isolation slot 15 on the top surface of the explosion-proof enclosure 1 are assembled and inserted. Then, the vertical threads on the top pressure frame 17 on both sides of the vertical end face of the explosion-proof enclosure 1 are rotated to install the reinforcing screw 18. The rotating reinforcing screw 18 moves vertically downward and presses against the top surface of the pressure column 26 of the top plate 2, thereby ensuring the assembly stability of the top plate 2 and the explosion-proof enclosure 1. At the same time, the reinforcing screw 18 is used to press against and protect the top plate 2. The assembly of the top plate 2 and the explosion-proof housing 1 is confirmed, which facilitates the rapid disassembly and assembly of the top plate 2 and the explosion-proof housing 1 in the later stage. In order to anchor and ensure the assembly stability of the explosion-proof housing 1 and the top plate 2, the anchor rod 23 on the hole seat 22 is pulled to drive the compression spring 25 to deform. Then, the bracket 11 on the explosion-proof housing 1 and the insertion frame 24 on the top plate 2 are slidably inserted. The anchor rod 23 is released and pushed into the anchor insertion hole 12 of the bracket 11 under the deformation force of the compression spring 25, thus anchoring and ensuring the assembly stability of the explosion-proof housing 1 and the top plate 2.

[0027] The above are preferred embodiments of this utility model. Those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments described above. Any obvious improvements, substitutions or modifications made by those skilled in the art based on this utility model shall fall within the protection scope of this utility model.
