Description

Technical Field

[0001] This utility model relates to the technical field of mining, and in particular to an explosion-proof underground power isolation box for mining. Background Technology

[0002] Explosion-proof underground power isolation boxes for mining are safety devices specifically designed for high-risk mining environments, focusing on improving the safety and reliability of power systems. These devices possess superior explosion-proof performance, effectively resisting explosive impacts in mining environments containing flammable gases and protecting internal electrical components from damage.

[0003] In existing power isolation boxes, the internal circuitry is completely exposed when the end cover is opened for maintenance or inspection, without any effective shielding. This design flaw allows dust from underground mines to easily enter the power isolation box, leading to the following problems:

[0004] Decreased electrical performance: Dust accumulation may cause short circuits or poor contact between electronic components on the circuit board, seriously affecting the normal operation of the power isolation box; Reduced heat dissipation efficiency: Dust covering the heat sink or other heat dissipation components will hinder the effective dissipation of heat, thereby causing the equipment to overheat and shorten its service life; Increased safety hazards: Especially in the mining environment containing flammable gases, the explosive substances formed by the mixture of dust and air may cause serious safety accidents if they come into contact with an electric spark. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an explosion-proof underground power isolation box for mining. It has a simple structure and a dustproof mechanism is set between the end cover and the box body. When the end cover is opened, it still protects the exposed box body and reduces the entry of dust.

[0006] This utility model discloses an explosion-proof underground power isolation box for mining, which includes a box body and an end cover; it also includes a dustproof mechanism.

[0007] The dustproof mechanism is installed on the opening side of the enclosure to isolate the internal space of the enclosure from the outside.

[0008] The dustproof mechanism is made of transparent material.

[0009] As a preferred embodiment of the present invention, the dustproof mechanism includes at least one dustproof component;

[0010] One end of the dustproof component is rotatably mounted on the enclosure or at least partially connected to the enclosure.

[0011] As a preferred embodiment of this utility model, the dustproof component includes:

[0012] The support is ring-shaped and is installed on the opening side of the housing.

[0013] The shielding part is used to cover the gaps in the support part, and the shielding part is made of transparent material.

[0014] As a preferred embodiment of this utility model, a recessed groove is provided on the open side of the box body; the support part is installed in the recessed groove.

[0015] As a preferred embodiment of this utility model, the support is installed on the inner wall of the box opening side.

[0016] As a preferred embodiment of this utility model, the shielding part has at least one through hole;

[0017] The dustproof components also include:

[0019] As a preferred embodiment of this utility model, a flexible strip connects the shielding sheet and the shielding part.

[0020] As a preferred embodiment of this utility model, the shielding sheet is made of transparent material.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows: the box and the end cover constitute the entire explosion-proof mine underground power isolation. Necessary electrical components are installed inside the box. When the end cover is opened, the dustproof mechanism is set on the opening side of the box to isolate the internal space of the box from the outside world, and the inside of the box still maintains a relatively closed environment, reducing the risk of dust intrusion. When more detailed maintenance or inspection is required, maintenance personnel can first observe the internal condition of the box through the transparent part to assess whether it is necessary to fully open the end cover for further operation. This design reduces unnecessary physical contact, thereby reducing the risk of dust intrusion. Attached Figure Description

[0028] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. Example

[0031] Reference Figure 1 This embodiment provides an explosion-proof underground power isolation box for mining, including a box body 3 and an end cover 4; it also includes a dustproof mechanism 1;

[0032] The dustproof mechanism 1 is installed on the opening side of the box 3 to isolate the internal space of the box 3 from the outside.

[0033] Part 1 of the dustproof mechanism is made of transparent material;

[0034] The specific usage process of this device is as follows: The housing 3 and the end cover 4 constitute the entire explosion-proof mine underground power isolation system. Necessary electrical components are installed inside the housing 3. When the end cover 4 is opened, the dustproof mechanism 1, located on the opening side of the housing 3, isolates the internal space of the housing 3 from the outside world, maintaining a relatively closed environment inside the housing 3 and reducing the risk of dust intrusion. When more detailed maintenance or inspection is required, maintenance personnel can first observe the internal condition of the housing 3 through the transparent part to assess whether it is indeed necessary to fully open the end cover 4 for further operation. This design reduces unnecessary physical contact, thereby reducing the risk of dust intrusion. Once the fault location is located, the dustproof mechanism 1 can be opened for maintenance.

[0035] As a preferred embodiment of the present invention, the dustproof mechanism 1 includes at least one dustproof component 11;

[0036] One end of the dustproof component 11 is rotatably mounted on the housing 3 or at least partially connected to the housing 3;

[0037] More specifically, the structure in which the dustproof assembly 11 is rotatably mounted on the housing 3 is a hinged connection (not shown), similar to a door switch. If this method is used, seals need to be installed around the dustproof assembly 11 to improve sealing; see reference... Figure 1 The dustproof component 11 is at least partially connected to the housing 3 by means of Velcro or magnetic attachment;

[0038] The dustproof component 11 can be a single unit arranged on the opening side of the housing 3, or two or more dustproof components 11 can be arranged on the opening side of the housing 3. Furthermore, the installation configuration of the dustproof components 11 can be freely combined. In this embodiment, refer to... Figure 1 There are two dustproof components 11, both of which are partially connected. If they are installed on the housing 3 by rotating connection, the dustproof component 11 can be rotated around the hinge when it is opened. If they are installed by Velcro or magnetic attraction, the dustproof component 11 can be pulled when it is opened.

[0039] As a preferred embodiment of this utility model, refer to Figure 3 The dustproof component 11 includes:

[0040] The support part 1101 is ring-shaped and is installed on the opening side of the housing 3. More specifically, when the dustproof component 11 is installed on the housing 3 by rotation, the material of the support part 1101 is rigid; when the dustproof component 11 is installed on the housing 3 by attachment, the material of the support part 1101 is flexible, such as cloth.

[0041] The shielding part 1102 is used to cover the gap in the support part 1101, which is the middle position of the annular support part 1101. The shielding part 1102 is made of transparent material. More specifically, the transparent material can be glass or plastic, and the specific type to be selected needs to be determined according to the material of the support part 1101.

[0042] As a preferred embodiment of this utility model, the box body 3 has a recessed groove 2 on its open side; the support part 1101 is installed in the recessed groove 2, more specifically, as shown in... Figure 2 As shown, the sink 2 is located on the plane of the opening side of the box 3. By reasonably designing the size and shape of the sink 2, the space occupied by the dustproof mechanism 1 can be reduced as much as possible without affecting the function, making the entire power isolation box 3 more compact and adaptable to the limited space conditions in the mine.

[0043] As a preferred embodiment of this utility model, the support part 1101 is installed on the inner wall of the opening side of the box 3 (not shown). This method has a simple structure and does not require much processing of the structure of the box 3.

[0044] As a preferred embodiment of this utility model, refer to Figure 5 The shielding part 1102 shall have at least one through hole. The position of the through hole shall be close to the electrical components inside the box 3 so that it is easy to reach into the box 3 for maintenance. The number and position of the through holes shall be adjusted according to the position and number of electrical components inside the box 3.

[0045] Dustproof component 11 also includes:

[0046] Reference Figure 3 The shielding piece 1103 is detachably installed at the through hole. More specifically, the shielding piece 1103 can be fixed at the through hole using a snap-on, screw, magnetic, sliding, or Velcro structure to achieve quick assembly and disassembly. In this embodiment, it is fixed at the through hole using Velcro.

[0047] The specific usage method of the shield 1103 is as follows: When it is necessary to maintain the electrical components inside the box 3, first determine the area to be worked on, and find the through hole on the shield 1102 near the area. Remove the shield 1103, and the staff can directly put their hands into the box 3 to perform necessary maintenance work, such as replacing parts, adjusting settings, or cleaning.

[0048] As a preferred embodiment of this utility model, refer to Figure 4 A flexible strip 1104 connects the shielding plate 1103 and the shielding part 1102. More specifically, the flexible strip 1104 is made of a deformable material, such as plastic. The flexible strip 1104 connects the shielding plate 1103 and the shielding part 1102, so that even if the shielding plate 1103 is removed for maintenance, it will not be easily lost, which is especially important for complex working environments such as mines.

[0049] As a preferred embodiment of this utility model, the shielding sheet 1103 is made of transparent material. More specifically, using a transparent shielding sheet 1103 can reduce blind spots and make it easier to determine faults.
