Description

Technical Field

[0001] This utility model relates to the field of lighting signal maintenance technology, specifically to a mine explosion-proof safety integrated protection device for lighting signals. Background Technology

[0002] The explosion-proof safety integrated lighting and signal protection device for mines is an electrical device specifically designed for the underground environment of coal mines. It is primarily used to provide power control and protection for 127V lighting and signal loads in mines containing explosive gases (such as methane) and coal dust. This device possesses multiple protection functions to ensure safe use in underground coal mines.

[0003] During maintenance of existing mine explosion-proof safety integrated lighting and signal protection devices, personnel can open the door inside the integrated lighting and signal protection housing and then turn off the switch of the lighting and signal unit inside the protection housing to repair the components of the integrated lighting and signal protection.

[0004] Although the above equipment can protect the lighting signal unit, when personnel are inspecting the lighting signal unit underground, dust from the mine can enter the housing when the protective housing door is opened. This indirectly prevents personnel from turning off the power switch in advance, which can cause the lighting signal unit to short-circuit. Utility Model Content

[0005] In view of this, the present invention provides a mine explosion-proof safety integrated protection device for lighting signals. The present invention can quickly cut off the power to the lighting signal components, thereby facilitating personnel to inspect and maintain the lighting signal components.

[0006] To address the aforementioned technical problems, this utility model provides a mine explosion-proof safety integrated protection device for lighting signals, comprising a protective housing, a support frame fixed inside the protective housing by bolts, a lighting signal element mounted on the support frame, a control switch on the upper surface of the support frame, the control switch being electrically connected to the lighting signal element, an explosion-proof door hinged to the side of the protective housing, and a power protection component inside the protective housing, the power protection component including a sliding frame inside the protective housing, a sliding block inside the sliding frame, and a top contact block on the side of the sliding block, the top contact block contacting the upper surface of the control switch; that is, when personnel open the explosion-proof door, the power protection component is triggered, causing the sliding block to move, thereby disengaging the sliding block from the control switch, thus de-energizing the lighting signal element and providing protection for the lighting signal element.

[0007] The power protection component also includes a spring installed inside the slide rail, with both ends of the spring fixed to one side of the slide rail and the side of the sliding block, respectively; that is, the spring provides elastic support for the sliding block.

[0008] The power protection assembly also includes multiple guide grooves provided on the inner wall of the protective housing and the side of the explosion-proof door. A tension rope is provided inside the protective housing. The tension rope passes through the perforations in the multiple guide grooves and the perforation on one side of the slide block and is fixed to the side of the sliding block; that is, the guide grooves facilitate the guidance of the tension rope.

[0009] The power protection assembly also includes a fixing block disposed at the end of the tension rope, the fixing block being located at the side end of the guide groove on the explosion-proof door; that is, the fixing block provides a limit for the tension rope, thereby preventing the tension rope from dislodging from the guide groove.

[0010] The power protection component also includes a threaded rod disposed on one side of the guide groove, which is in contact with one side of the sliding block; that is, the threaded rod can limit the sliding block by contact.

[0011] The power protection assembly also includes a drive button located at the end of the threaded rod; that is, the drive button can drive the threaded rod.

[0012] The top contact block has an arc-shaped end, and a groove is provided in the middle of the upper surface of the control switch. The top contact block is located inside the groove, which facilitates the top contact block entering the upper surface of the control switch.

[0013] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0014] 1. By setting up a power protection component, when personnel open the explosion-proof door, the tension rope will be triggered, which will pull the sliding block in the slide rail. This will cause the sliding block to move the top contact block away from the button on the control switch. This will turn off the lighting signal element inside the explosion-proof door during the opening process, preventing dust from entering the explosion-proof door and causing a short circuit in the lighting signal element.

[0015] 2. By setting the threaded rod on the side of the slide rail, the threaded rod will contact the sliding block during the rotation of the threaded rod, causing the sliding block to drive the contact block away from the button on the control switch, thereby facilitating the closing of the explosion-proof door and stopping the operation of the lighting signal element.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-4 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0024] like Figure 1-4As shown: This embodiment provides a mine explosion-proof safety integrated protection device for lighting and signals, including a protective housing 100. A support frame 103 is bolted inside the protective housing 100, and a lighting signal element 102 is mounted on the support frame 103. The support frame 103 provides support for the lighting signal element 102. A control switch 104 is provided on the upper surface of the support frame 103, and the control switch 104 is electrically connected to the lighting signal element 102. The control switch 104 is used to control the operation of the lighting signal element 102 by pressing a button. An explosion-proof door 101 is hinged to the side of the protective housing 100 to prevent dust and other contaminants from entering the protective housing 100. A power protection component 200 is provided inside the protective housing 100, including a sliding frame 201 installed inside the protective housing 100. The sliding frame 201 is fixed to the protective housing by welding or bolts. Inside the protective housing 100, the housing 100 provides support for the slide rail 201. A sliding block 209 is provided inside the slide rail 201, which can slide within the slide rail 201, thus providing guidance for the sliding block 209. A top contact block 207 is provided on the side end of the sliding block 209, which is fixed to the sliding block 209 by welding. The top contact block 207 contacts the upper surface of the control switch 104. When the top contact block 207 contacts the upper surface of the control switch 104, the lighting signal element 102 inside the protective housing 100 is activated. When the top contact block 207 leaves the control switch 104, the control switch 104 quickly shuts off the power to the lighting signal element 102 inside the protective housing 100, thus quickly disconnecting the power to the lighting signal element 102, facilitating personnel to inspect and maintain the lighting signal element 102.

[0025] When personnel need to maintain the lighting signal element 102 inside the protective housing 100, opening the explosion-proof door 101 triggers the operation of other parts in the power protection assembly 200, which in turn moves the top contact block 207 away from the control switch 104. This causes the control switch 104 to quickly de-energize the lighting signal element 102, facilitating maintenance. When the explosion-proof door 101 is closed, it triggers the operation of other parts in the power protection assembly 200 again, causing the top contact block to re-energize the control switch 104, which then energizes the lighting signal element 102.

[0026] Power protection component 200 Figure 2 Enlarged view of point A in the image is as follows Figure 3 As shown,

[0027] The power protection assembly 200 also includes a spring 202 disposed in the slide frame 201. The two ends of the spring 202 are fixedly disposed to one side of the slide frame 201 and the side of the sliding block 209, respectively, so that the spring 202 provides elastic support for the sliding block 209.

[0028] The power protection assembly 200 also includes multiple guide grooves 203 disposed on the inner wall of the protective housing 100 and the side of the explosion-proof door 101. The guide grooves 203 are fixed to the inner wall of the protective housing 100 by welding. A tension rope 204 is disposed inside the protective housing 100. The tension rope 204 passes through the perforations in the multiple guide grooves 203 and the perforation on one side of the slide frame 201 and is fixed to the side of the sliding block 209. The guide grooves 203 provide guidance for the tension rope 204, thereby facilitating personnel to pull the sliding block 209 and move the sliding block 209 within the slide frame 201.

[0029] The power protection assembly 200 also includes a fixing block 208 disposed on the end of the tension rope 204. The fixing block 208 is fixedly installed on the end of the tension rope 204 and is located on the side of the guide groove 203 on the explosion-proof door 101, thereby preventing the tension rope 204 from coming out of the guide groove 203.

[0030] When the explosion-proof door 101 is opened, the tension rope 204 moves within the guide groove 203, causing the tension rope 204 to move the sliding block 209. This indirectly causes the sliding block 209 to move the top contact block 207 away from the control switch 104. When the top contact block 207 moves away from the upper surface of the control switch 104, the control switch 104 de-energizes the lighting signal element 102, thus quickly de-energizing the lighting signal element 102. If the lighting signal element 102 is energized, closing the explosion-proof door 101 causes the spring 202 to rebound, moving the top contact block 207 so that it contacts the control switch 104, thus energizing the device.

[0031] Threaded rod 206 Figure 3 As shown,

[0032] The power protection assembly 200 also includes a threaded rod 206 disposed on one side of the guide groove 203, which is in contact with one side of the sliding block 209. If the lighting signal element 102 inside the protective housing 100 is not powered on by personnel, the threaded rod 206 is moved by the operation of the threaded rod 206, which then contacts the sliding block 209. This causes the sliding block 209 to slide the top contact block 207, which then moves away from the control switch 104. This allows the control switch 104 to de-energize the lighting signal element 102 for an extended period. To power the lighting signal element 102 again, the threaded rod 206 is rotated again to close the explosion-proof door 101, thus powering on the lighting signal element 102.

[0033] The power protection assembly 200 also includes a drive button 205 disposed on the end of the threaded rod 206, so as to facilitate the rotation of the drive button 205 by personnel;

[0034] Control switch 104, etc. Figure 2 As shown,

[0035] The top contact 207 has an arc-shaped end, and a groove is provided in the middle of the upper surface of the control switch 104. The top contact 207 is located inside the groove, which makes it easy for the top contact 207 to quickly slide into the upper surface of the control switch 104.

[0036] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0037] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
