Description

Technical Field

[0001] The utility model relates to the technical field of explosion-proof controllers, in particular to an explosion-proof controller for mining. Background Art

[0002] Mineral resources are the product of the long-term formation, development, and evolution of the Earth's crust. They are formed by the aggregation of natural minerals under certain geological conditions and through certain geological processes. Different geological processes can form different types of minerals.

[0003] Mining requires the use of electronic control components, which require controllers to control them. The controllers release heat when operating, but heat dissipation is difficult in mines. The dust in mines is high, which can easily clog the dust screens in the heat dissipation devices, preventing the heat from dissipating. If heat dissipation is not promptly addressed, it can easily cause controller failure. In severe cases, the controller can overheat, catch fire, and explode, shortening the lifespan of the equipment and potentially causing mine collapse and casualties. Therefore, we propose a new explosion-proof controller for mining. Utility Model Content

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is as follows: a mining explosion-proof controller, comprising a box body, symmetrical ventilation slots are provided on both sides of the box body, a dustproof net is fixedly connected to the inner cavity of the ventilation slots, a heat dissipation and dust removal assembly is symmetrically fixedly connected to the inner cavity of the box body, and the ventilation slots and the heat dissipation and dust removal assembly are on the same horizontal line, the side walls of the inner cavity of the box body are fixedly connected to the controller body, the top of the inner cavity of the box body is provided with a fire extinguishing assembly, the side walls of the inner cavity of the box body are provided with several temperature detectors, a box door is provided on one side of the box body, and a sealing assembly is provided on the box body and the box door, the sealing assembly includes an electromagnet, a baffle, a fixing rod, an iron block, a spring, and a fixing slot, the electromagnet is fixedly connected to the middle part of one side of the box door, two fixing slots are symmetrically fixedly connected to the edges of the two side walls of the box body, two baffles are symmetrically fixedly connected to one side of the box door, the fixing rod slides through the baffle, one side of the fixing rod is fixedly connected to the iron block, the iron block is magnetically connected to the electromagnet, the spring is slidably sleeved on the fixing rod and is located between the iron block and the baffle, and a door handle is provided on one side of the box door.

[0006] As a further description of the above technical solution, the heat dissipation and dust removal assembly includes a mounting bracket, a heat dissipation fan, and a cleaning brush. The mounting bracket is fixedly connected to the side wall of the inner cavity of the box, the heat dissipation fan is fixedly connected to one side of the mounting bracket, and several cleaning brushes are fixedly connected to the fan blades on the side of the heat dissipation fan close to the dustproof net, and the cleaning brushes are in contact with the dustproof net.

[0007] As a further description of the above technical solution, slide grooves are symmetrically fixedly connected to the top of the inner cavity of the box, and the fire extinguishing assembly is slidably connected to the two slide grooves.

[0008] As a further description of the above technical solution, the fire extinguishing assembly includes a storage box, a fire extinguishing groove, a low-temperature hot melt adhesive, a dry powder fire extinguishing agent, and a slider. The slider is slidably connected to the inner cavity of the slide groove, and the storage box is fixedly connected between the two sliders. The inner cavity of the storage box is sequentially provided with low-temperature hot melt adhesive and dry powder fire extinguishing agent from bottom to top, and a number of through fire extinguishing grooves are evenly opened at the bottom of the inner cavity of the storage box.

[0009] As a further description of the above technical solution, the electromagnet, baffle and fixing groove are on the same vertical line, and the two ends of the spring are fixedly connected to the iron block and the side wall of the baffle respectively.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. By setting up heat dissipation and dust removal components, dustproof nets, etc., in daily use, when the controller body needs to be cooled, the cooling fan can be started to discharge the heat in the inner cavity of the box to the external space. At the same time, several cleaning brushes are fixedly connected to the blades of the cooling fan, which can brush off the dust blocked on the dustproof net when the cooling fan rotates, effectively preventing the dustproof net mesh from being blocked by dust, resulting in heat unable to dissipate and accumulating on the controller body to cause damage.

[0012] 2. By providing fire extinguishing components and chutes, when the controller body overheats, causing the temperature of the box cavity to rise, the low-temperature hot melt adhesive will melt at temperatures above 60°C, allowing the dry powder fire extinguishing agent to be evenly sprayed from the fire extinguishing chute, thereby extinguishing the fire on the controller body. This can prevent the controller body from overheating and exploding, resulting in financial and personal casualties. At the same time, by sliding the slider out of the chute cavity, the low-temperature hot melt adhesive and dry powder fire extinguishing agent in the container cavity can be regularly inspected and replaced.

[0013] 3. By setting up temperature detectors, sealing components, etc., when the temperature detector in the inner cavity of the box detects that the temperature is higher than the set threshold, the controller body will first cut off the power to the inside to prevent the internal parts from continuing to heat up and causing a fire. At the same time, the electromagnet is powered off, and the electromagnet and the iron block are no longer magnetically attracted. Since the spring has been in a stretched state, the spring retracts at this time, driving the iron block and the fixing rod to move toward the fixing slot, so that the fixing rod is inserted into the inner cavity of the fixing slot, thereby fixing the box body and the box door, completing the locking and fixing of the box body. This can effectively avoid the situation where the controller body explodes and causes injuries to personnel due to the failure to cool down the controller body in time and the fire extinguishing component cannot extinguish the flame.

[0021] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "provided with," "connected," etc., should be understood in a broad sense. For example, "connected" may refer to a fixed connection, a detachable connection, or an integral connection; it may refer to a mechanical connection or an electrical connection; it may refer to a direct connection or an indirect connection through an intermediate medium; it may refer to internal communication between two components. Those skilled in the art will be able to understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0022] See also Figure 1-4 The present utility model provides a technical solution: a mining explosion-proof controller, comprising a housing 1, with ventilation slots 2 symmetrically formed on both sides of the housing 1. Dust screens 3 are fixedly connected to the inner cavity of the ventilation slots 2. Heat dissipation and dust removal assemblies 4 are symmetrically fixedly connected to the inner cavity of the housing 1, with the ventilation slots 2 and heat dissipation and dust removal assemblies 4 being on the same horizontal line. A controller body 7 is fixedly connected to the side walls of the inner cavity of the housing 1. A fire extinguishing assembly 5 is provided at the top of the inner cavity of the housing 1, and is located above the controller body 7. Several temperature sensors 6 are provided on the side walls of the inner cavity of the housing 1. A door 8 is provided on one side of the housing 1. A sealing assembly 9 is provided on the housing 1 and the door 8. The sealing assembly 9 includes an electromagnet 9.1, a baffle 9.2, and a fixing rod 9. 3. Iron block 9.4, spring 9.5, fixed groove 9.6, electromagnet 9.1 is fixedly connected to the middle of one side of the box door 8, and is located on the side where the box door 8 is opened. Two fixed grooves 9.6 are symmetrically fixedly connected to the edges of the two side walls of the box body 1, and two baffles 9.2 are symmetrically fixedly connected to one side of the box door 8. The fixed rod 9.3 slides through the baffle 9.2, and the baffle 9.2 plays a good limiting and guiding role on the fixed rod 9.3. An iron block 9.4 is fixedly connected to one side of the fixed rod 9.3. The iron block 9.4 is magnetically connected to the electromagnet 9.1. The spring 9.5 is slidably sleeved on the fixed rod 9.3 and is located between the iron block 9.4 and the baffle 9.2. A door handle 11 is provided on one side of the box door 8, and the box door 8 can be opened and closed by the door handle.

[0023] Specifically, such as Figure 2 As shown, the electromagnet 9.1, the baffle 9.2, and the fixing groove 9.6 are on the same vertical line, and the two ends of the spring 9.5 are fixedly connected to the iron block 9.4 and the side wall of the baffle 9.2 respectively. When the electromagnet 9.1 is started to absorb the iron block 9.4, the spring 9.5 is in a stretched state. When the temperature detector 6 in the inner cavity of the box body 1 detects that the temperature is higher than the set threshold, the controller body 7 first cuts off the power to the inside to prevent the internal parts from continuing to heat up and causing a fire. At the same time, the electromagnet 9.1 is powered off, and the electromagnet 9.1 and the iron block 9.4 are no longer magnetically attracted to each other. Since the spring 9.5 has been in a stretched state, the spring 9.5 retracts at this time, driving the iron block 9.4 and the fixing rod 9.3 to move toward the fixing groove 9.6, so that the fixing rod 9.3 is inserted into the inner cavity of the fixing groove 9.6, thereby fixing the box body 1 and the box door 8, completing the locking and fixing of the box body 1. This can effectively avoid the situation where the controller body 7 explodes and causes injuries to personnel due to the controller body 7 not cooling down in time and the fire extinguishing component 5 failing to extinguish the flame.

[0024] Specifically, such as Figure 4As shown, the heat dissipation and dust removal assembly 4 includes a mounting frame 4.1, a heat dissipation fan 4.2, and a cleaning brush 4.3. The mounting frame 4.1 is fixedly connected to the side wall of the inner cavity of the housing 1, and the heat dissipation fan 4.2 is fixedly connected to the side of the mounting frame 4.1 close to the dustproof net 3. A plurality of cleaning brushes 4.3 are fixedly connected to the blades of the heat dissipation fan 4.2 close to the dustproof net 3, and the blades with the cleaning brushes 4.3 are arranged at intervals, and the cleaning brushes 4.3 fit the dustproof net 3. In daily use, when it is necessary to dissipate heat from the controller body 7, the heat dissipation fan 4.2 can be started to discharge the heat from the inner cavity of the housing 1 to the external space. At the same time, a plurality of cleaning brushes 4.3 are fixedly connected to the blades of the heat dissipation fan 4.2, so that the dust blocked on the dustproof net 3 can be brushed off when the heat dissipation fan 4.2 rotates, effectively preventing the mesh of the dustproof net 3 from being clogged with dust, resulting in heat being unable to dissipate and accumulating on the controller body 7 and causing damage.

[0025] Specifically, such as Figure 4 As shown, slide grooves 10 are symmetrically fixedly connected to the top of the inner cavity of the box body 1, and the fire extinguishing component 5 is slidably connected to the two slide grooves 10.

[0026] The fire extinguishing assembly 5 includes a container 5.1, a fire extinguishing trough 5.2, a low-temperature hot-melt adhesive 5.3, a dry powder fire extinguishing agent 5.4, and a slider 5.5. The slider 5.5 is slidably connected to the inner cavity of the trough 10. The container 5.1 is fixedly connected between the two sliders 5.5. The inner cavity of the container 5.1 is provided with low-temperature hot-melt adhesive 5.3 and dry powder fire extinguishing agent 5.4 in sequence from bottom to top. A plurality of fire extinguishing troughs 5.2 are evenly distributed at the bottom of the inner cavity of the container 5.1. The low-temperature hot-melt adhesive 5.3 will melt at a temperature above 60°C and flow out of the fire extinguishing troughs 5.2, allowing the dry powder fire extinguishing agent 5.4 in the upper layer to be sprayed evenly. When the controller body 7 overheats, causing the temperature of the interior of the housing 1 to rise, the low-temperature hot melt adhesive 5.3 melts at temperatures above 60°C, allowing the dry powder fire extinguishing agent 5.4 to be evenly sprayed from the fire extinguishing trough 5.2, thereby extinguishing the fire in the controller body 7 and preventing the controller body 7 from overheating and exploding, which could cause financial and personal casualties. Furthermore, by sliding the slider 5.5 out of the chute 10, the low-temperature hot melt adhesive 5.3 and dry powder fire extinguishing agent 5.4 in the interior of the housing 5.1 can be regularly inspected and replaced.

[0027] It should be noted that the present invention is an explosion-proof controller for mining. In daily use, when the controller body 7 needs to be cooled, the cooling fan 4.2 can be started to discharge the heat in the inner cavity of the box 1 to the external space. At the same time, a number of cleaning brushes 4.3 are fixedly connected to the blades of the cooling fan 4.2, which can brush off the dust blocked on the dust net 3 when the cooling fan 4.2 rotates, effectively preventing the mesh of the dust net 3 from being clogged with dust, resulting in the inability to dissipate heat and accumulating on the controller body 7 to cause damage.

[0028] When the temperature of the controller body 7 is too high, causing the temperature of the inner cavity of the box 1 to rise, the low-temperature hot melt adhesive 5.3 will melt when the temperature is higher than 60°, so that the dry powder fire extinguishing agent 5.4 can be evenly sprayed from the fire extinguishing trough 5.2, thereby extinguishing the fire in the controller body 7, thereby preventing the controller body 7 from overheating and exploding, causing financial and personal casualties.

[0029] When the temperature detector 6 in the inner cavity of the box body 1 detects that the temperature is higher than the set threshold, the controller body 7 first cuts off the power to the inside to prevent the internal parts from continuing to heat up and causing a fire. At the same time, the electromagnet 9.1 is powered off, and the electromagnet 9.1 and the iron block 9.4 are no longer magnetically attracted to each other. Since the spring 9.5 has been in a stretched state, the spring 9.5 retracts at this time, driving the iron block 9.4 and the fixing rod 9.3 to move toward the fixing groove 9.6, so that the fixing rod 9.3 is inserted into the inner cavity of the fixing groove 9.6, thereby fixing the box body 1 and the box door 8, completing the locking and fixing of the box body 1. This can effectively avoid the situation where the controller body 7 explodes and causes injuries to personnel due to the controller body 7 not cooling down in time and the fire extinguishing component 5 failing to extinguish the flame.
