DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] See also Figure 1-6 The present invention provides a technical solution: a mine equipment safety early warning system, comprising a fixed plate 1 and a power module 4, the power module 4 is installed on the top of the fixed plate 1, an inner cavity 12 is provided inside the fixed plate 1, an adjusting cavity 15 is provided inside the fixed plate 1, a sealing block 13 is provided inside the inner cavity 12, the top of the sealing block 13 and the inner top surface of the inner cavity 12 are sealed to each other, an adjusting component for adjusting the sealing strength of the sealing block 13 is provided inside the adjusting cavity 15, and a flow block for limiting the flow size is provided on the inner side of the fixed plate 1 close to the inner cavity 12;

[0031] A flow guide tube 9 is provided on the other side of the interior of the fixing plate 1 near the inner cavity 12. Both ends of the flow guide tube 9 extend to the outside of the fixing plate 1. A through hole 32 is provided on the inner wall of one side of the inner cavity 12 and penetrates to the outside of the fixing plate 1. The through hole 32 is connected to the flow guide tube 9 (such as Figure 6 As shown in the figure, an opening and closing component for controlling the opening and closing of the flow guide tube 9 is arranged inside the through hole 32, an input pipe 2 is fixed on one side of the fixed plate 1, and one end of the input pipe 2 passes through the top of the inner cavity 12, an output pipe 3 is fixed on one side of the fixed plate 1, and one end of the output pipe 3 passes through the side wall of the inner cavity 12, a plurality of indicator lights 5 are fixed on the top of the power module 4, and a plurality of electrical connectors 6 are installed on the power module 4, a receiving groove 7 is provided on the front side of the fixed plate 1, the receiving groove 7 is communicated with the regulating cavity 15, a separating ring 27 is fixed between the receiving groove 7 and the regulating cavity 15, a probe rod 11 is fixed on the rear side of the fixed plate 1 and passes through the inner cavity 12, a plurality of drainage holes 24 passing through the two ends of the probe rod 11 are equidistantly provided inside the probe rod 11 along the circumferential direction, the top of the sealing block 13 is concave, and one end of the probe rod 11 extends to the concave interval at the top of the sealing block 13.

[0032] It should be noted that when using this device, it is first necessary to connect the input pipe 2 to the external hydraulic supply equipment, and then connect the output pipe 3 to the hydraulic power element of the mining equipment, so that the externally supplied hydraulic energy can enter the interior of the mining equipment after passing through this device.

[0033] The effect achieved is that the top of the sealing block 13 is sealed with the inner top surface of the inner cavity 12 so that the top of the sealing block 13 can be sealed with the outlet of the input pipe 2. The sealing strength between the sealing block 13 and the inner cavity 12 can be changed by adjusting the component, thereby changing the minimum pressure value of the hydraulic oil entering the inner cavity 12. When adjusting the adjusting component, the flow blocking member can also be driven to work to prevent the situation where the flow rate increases due to excessive hydraulic energy and a large pressure drop occurs. A guide tube 9 is arranged inside the fixed plate 1, so that one end of the guide tube 9 is connected to the external cooling gas, and the other end is passed into the interior of the equipment. At the same time, when a large pressure drop occurs, the opening and closing assembly will be triggered The device introduces external cooling gas into the device to cool down the inside of the device to prevent other accidents. A probe rod 11 is set on the fixed plate 1, and one end of the probe rod 11 is extended to the recessed area at the top of the sealing block 13, so that a seal can be formed between the probe rod 11 and the sealing block 13 located inside the inner cavity 12 to prevent liquid leakage inside the inner cavity 12. When the device produces a large pressure drop, it means that the flow rate flowing through the inner cavity 12 is large, and it can also be judged that the distance between the top of the sealing block 13 and the top of the inner cavity 12 is large. When the top of the sealing block 13 slides to separate from the bottom of the probe rod 11, the liquid inside the inner cavity 12 can flow out from the drainage hole 24 to alarm people.

[0034] like Figure 3 , Figure 4 and Figure 5 As shown, the adjustment assembly includes a threaded rod 28, which is threadedly connected between the inner walls of the separation ring 27, one end of the threaded rod 28 extends to the interior of the adjustment chamber 15, one end of the threaded rod 28 located in the adjustment chamber 15 is rotatably connected to a movable plate 29, and the other end of the threaded rod 28 is fixed with an adjustment block 8, a first spring 16 is fixed to the top of the movable plate 29, a lifting plate 17 is fixed to the top of the first spring 16, and the lifting plate 17 is located in the adjustment chamber 15, a connecting rod 14 is fixed to the bottom of the sealing block 13, the bottom of the connecting rod 14 slides through the interior of the adjustment chamber 15, and is fixed to the top of the lifting plate 17, guide grooves 30 are opened on both sides of the inner wall of the adjustment chamber 15, and guide blocks 31 slidably connected to the inside of the guide grooves 30 are fixed to the outer surfaces of both sides of the movable plate 29.

[0035] The effect achieved is that by arranging the separation ring 27 between the receiving groove 7 and the adjusting chamber 15, it is convenient to connect the threaded rod 28, so that people can adjust the adjusting assembly from the outside. By rotating the adjusting block 8 to drive the threaded rod 28 to rotate, the movable plate 29 can be pushed toward the lifting plate 17, thereby compressing the first spring 16 and changing the sealing force between the sealing block 13 and the inner cavity 12. When pushing the movable plate 29 to slide, the mutual engagement of the guide groove 30 and the guide block 31 makes the sliding of the movable plate 29 smoother. Fixing the connecting rod 14 between the bottom of the sealing block 13 and the top of the lifting plate 17 helps to transmit the elastic pressure generated by the first spring 16 to the sealing block 13, so that the elastic pressure is converted into the sealing strength between the sealing block 13 and the inner cavity 12, wherein the displacement of the movable plate 29 does not reach the middle of the adjusting chamber 15 When the movable plate 29 is in the middle position of the regulating chamber 15, it means that the minimum pressure limit entering the inner cavity 12 is low pressure. It is not easy to produce instantaneous pressure drop under low pressure, so the baffle is in a non-triggered state. When the movable plate 29 is displaced to reach the middle position of the regulating chamber 15, it means that the minimum pressure limit entering the inner cavity 12 is medium-high pressure. At this time, the baffle is in a triggered state. When an instantaneous pressure drop occurs, the baffle reduces the on-off area of ​​the output pipe 3, thereby reducing the flow rate per unit time, so as to achieve the purpose of buffering the instantaneous pressure drop. When in use, the position of the movable plate 29 is manually adjusted when the sealing clamping force of the sealing block 13 is changed. When the sealing clamping force of the sealing block 13 is low, the movable plate 29 is at the lowest position of the regulating chamber 15. When the sealing clamping force of the sealing block 13 is adjusted to a certain height, the movable plate 29 is in the middle position of the regulating chamber 15.

[0036] like Figure 3 , Figure 4 and Figure 5 As shown, the flow blocking member includes a cut-off plate 20, a side opening 19 is opened on the inner wall of the output pipe 3, the cut-off plate 20 is slidably sealed and connected inside the side opening 19, a reciprocating cavity 18 is opened on the side wall of the fixed plate 1, an adjusting rod 21 is slidably arranged inside the reciprocating cavity 18, the top of the adjusting rod 21 slides through the inside of the side opening 19 and is fixed to the bottom of the cut-off plate 20, an annular protrusion is provided on the outer surface of the adjusting rod 21, a second spring 25 is fixed between the top of the annular protrusion on the outer surface of the adjusting rod 21 and the inner top surface of the reciprocating cavity 18, and a through opening 22 (such as Figure 5 As shown in the figure, a contact block 23 is slidably provided inside the through-opening 22, a wedge-shaped opening 26 is provided on the top of the contact block 23, one end of the contact block 23 is triangularly inclined and extends to the inside of the guide groove 30, the bottom of the adjusting rod 21 slides through the inside of the through-opening 22, and the bottom of the adjusting rod 21 fits with the inclined surface of the wedge-shaped opening 26.

[0037] The effect achieved is that an adjusting rod 21 is slidably arranged inside the reciprocating chamber 18, so that the action of the cut-off plate 20 can be correlated with the contact block 23 through the adjusting rod 21, and a second spring 25 is fixed between the top of the annular protrusion on the outer surface of the adjusting rod 21 and the inner top surface of the reciprocating chamber 18. The elastic pressure of the second spring 25 drives the cut-off plate 20 to return to the inside of the side opening 19 when the contact block 23 is not squeezed. At the same time, when the flow blocking member is reset, the contact block 23 is reset by the elastic pressure of the second spring 25, and when the flow blocking member is triggered, the movable plate 29 is moved up to the adjusting position. After the contact block 23 reaches the middle part of the cavity 15, it squeezes the contact block 23 toward the inside of the through-port 22, and the adjusting rod 21 is lifted upward under the push of the inclined surface of the wedge-shaped port 26, thereby driving the cut-off plate 20 to reduce the opening of the output pipe 3, so that the flow rate flowing through per unit time is reduced to prevent the pressure drop from being too large. One end of the contact block 23 is triangularly inclined and extends to the inside of the guide groove 30, so as to facilitate contact with the guide block 31, and the bottom of the adjusting rod 21 is fitted with the inclined surface of the wedge-shaped port 26, and the adjusting rod 21 can be moved up and down through the inclined surface of the wedge-shaped port 26.

[0038] like Figure 3 and Figure 6 As shown, the opening and closing assembly includes an adjusting column 33, which is slidably arranged inside the through hole 32, and one end of the adjusting column 33 extends to the inside of the inner cavity 12, and a through hole 34 is opened on the outer surface of the adjusting column 33, and the through hole 34 can be connected with the guide tube 9 after moving in the direction of the hexagonal rod 36, and a fixing sleeve 10 is fixed to the outer surface of the fixing plate 1, and the inner wall of the fixing sleeve 10 is flush with the inner wall of the through hole 32, and a hexagonal rod 36 is fixed to one end of the adjusting column 33, and one end of the hexagonal rod 36 slides through the outside of the fixing sleeve 10, and a third spring 35 is fixed between one end of the adjusting column 33 and one side inner wall of the fixing sleeve 10.

[0039] The effect achieved is that when an instantaneous pressure drop occurs, the sealing block 13 will slide downward a large distance, and the adjusting column 33 will be squeezed into the through hole 32 under the contact of the inclined surface of the sealing block 13, so that the through hole 34 and the guide tube 9 are interconnected, thereby introducing the external cooling gas into the interior of the equipment, and the third spring 35 is used to reset the adjusting column 33 when resetting. At the same time, the hexagonal rod 36 is used to guide the adjusting column 33 when it slides, which can prevent the adjusting column 33 from rotating during the sliding process and twisting the third spring 35 off.

[0040] Working principle: When using this device, you first need to connect the input pipe 2 to the external hydraulic supply equipment, and then connect the output pipe 3 to the hydraulic power element of the mining equipment, so that the externally supplied hydraulic energy can enter the interior of the mining equipment after passing through this device. At the same time, connect one end of the guide pipe 9 to the external cooling gas supply source, and connect the other end of the guide pipe 9 to the hydraulic oil cooling system and transmission structure and electronic control components inside the mining equipment. During cooling, the cooling gas uses carbon dioxide dry ice to achieve the purpose of cooling and flame retardancy. At the same time, it is also necessary to connect one end of the probe rod 11 to the external alarm device. At this time, when the mining equipment is overloaded and works for a long time, the temperature of the hydraulic oil will rise, and the rise in hydraulic oil temperature will cause its viscosity. The degree decreases, thereby accelerating the flow rate of the hydraulic oil inside the pipeline. When the flow is faster, the sealing block 13 will be pressed downward. When the downward displacement is large, an instantaneous pressure drop will be generated. While the pressure drop is generated, the rate of pressure drop can be slowed down under the action of the baffle. At the same time, the opening and closing components are triggered to introduce external cooling gas into the interior of the mining equipment to cool the hydraulic oil while preventing other electronic devices from causing fires. When the top of the sealing block 13 slides to the bottom of the probe rod 11, the hydraulic oil inside the inner cavity 12 can flow from the drainage hole 24 to the external alarm facility, triggering the alarm facility to achieve the alarm effect. Before the alarm, the opening and closing components and the baffle have already dealt with the pressure drop in the first time, thereby eliminating hidden dangers.

[0041] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
