Its main function is to generate electricity to supply mining equipment, lighting fixtures and other mining electrical equipment. During use, when the cable is connected to the generator, the generator may leak electricity due to reasons such as loose core wire connection, loose blockage or loose pressure plate, or the joint may fall off or loosen during operation or movement. If the leakage is not discovered in time, it can easily cause power outages to equipment in the mine, affecting production progress, and easily causing fire or explosion accidents, increasing the risk of accidents and reducing the personal safety of workers.

A pressure sensor 2108 is fixedly connected to the inner wall of the slide 2105, one end of the extrusion rod 2107 contacts the detection end of the pressure sensor 2108, and an extrusion plate 2109 is slidably connected to the inner cavity of the slide 2105, one side of the extrusion plate 2109 contacts one side of the push block 2104, and the other side of the extrusion plate 2109 contacts one end of the extrusion rod 2107; by setting the magnetic field monitoring unit 21, the change of the current flow can be timely known according to the change of the magnetic field, and the leakage situation can be timely known, which is convenient for maintenance personnel to timely inspect and repair the generator body 1, reducing the risk of accidents and ensuring the personal safety of workers.

[0035] Two limiting grooves 2110 are relatively opened on the inner side of the slide groove 2105, and limiting blocks 2111 are fixedly connected on both sides of the extrusion plate 2109, and the surface of the limiting block 2111 is slidably connected to the inner cavity of the limiting groove 2110; by setting the limiting groove 2110 and the limiting block 2111 for coordinated use, the limiting block 2111 can slide in the limiting groove 2110 through the engagement, so as to guide the moving trajectory of the extrusion plate 2109 and ensure the stability of the extrusion plate 2109 during movement.

[0036] A spring 2112 is sleeved on the surface of the extrusion rod 2107, and the two ends of the spring 2112 are respectively fixedly connected to one side of the support plate 2106 and the surface of the extrusion rod 2107; by setting the spring 2112, an elastic connection between the extrusion rod 2107 and the support plate 2106 can be achieved, and the reaction force of the spring 2112 can achieve the resetting of the extrusion rod 2107.

[0037] One side of the concave block 2101 is fixedly connected to a limit rod 2113 , and the limit rod 2113 is used to limit the rotation angle of the push block 2104 .

[0038] The specific implementation of this embodiment is as follows: when the power generation component 12 operates normally, a magnetic field perpendicular to the direction of the current is generated around the cable, and the end of the magnetic block 2103 close to the cable is opposite to the magnetic pole of the magnetic field. According to the principle of opposite poles attracting each other, the magnetic field attracts the magnetic block 2103, causing the magnetic block 2103 to move. In the initial state, the extrusion rod 2107 contacts the detection end of the pressure sensor 2108, and the magnetic block 2103 is driven by the magnetic field through the connecting rod 2102 and the bearing to rotate. The rotation of the magnetic block 2103 drives the push block 2104 to rotate, and the push block The rotation of 2104 pushes the extrusion plate 2109, and the extrusion plate 2109 is guided by the limit groove 2110 and the limit block 2111. The movement of the extrusion plate 2109 pushes the extrusion rod 2107, and the movement of the extrusion rod 2107 compresses the spring 2112. The extrusion rod 2107 moves a distance on the inner wall of the support plate 2106, and squeezes the detection end of the pressure sensor 2108, so that the pressure sensor 2108 generates a value. This value will be in a stable state under the condition of a constant magnetic field. When the generator body 1 generates When leakage occurs, the amount of current passing through the cable changes, the magnetic field near the cable weakens, and the magnetic attraction to the magnetic block 2103 weakens. At this time, the reaction force of the spring 2112 drives the extrusion rod 2107 to move in the opposite direction, and the extrusion force on the pressure sensor 2108 is reduced, so that the value transmitted by the pressure sensor 2108 to the external warning device becomes smaller. When an irregular value is generated, the warning condition is triggered. Under normal circumstances, due to the stability of the magnetic field, the pressure transmitted to the pressure sensor 2108 is constant, and the pressure value is stable. The external warning device sets the warning trigger condition as irregular data fluctuation in advance. Therefore, when the pressure sensor 2108 transmits an irregular value, the signal is transmitted to the external controller through the pressure sensor 2108, so that the warning device is started through the external controller to remind the maintenance personnel that the generator body 1 at this location has a leakage fault. This is an existing mature technology, so it is not elaborated in detail, so that the leakage situation can be known in time, which is convenient for the maintenance personnel to timely inspect the generator body 1, reduce the risk of accidents, and ensure the personal safety of workers.

[0039] Example 2: Please refer to Figure 1 - Fig. 9 The present invention provides a technical solution: a safety performance detection device for a mining generator. The present invention makes corresponding improvements to the technical problems mentioned in the background technology.

[0040] As a further limitation of the leakage detection mechanism 2 of the present invention, the current detection unit 22 includes a plurality of support bars 2201, and the plurality of support bars 2201 are fixedly connected to one side of the base 11 by bolts. The tops of the plurality of support bars 2201 are commonly fixedly connected to a support plate 2202, and one side of the support plate 2202 is provided with a plurality of conductors 2203, and the conductors 2203 are made of copper. One end of the conductor 2203 is fixedly connected to a guide plate 2204, and the guide plate 2204 is made of copper. One side of the guide plate 2204 is tightly fitted with the surface of the power generation component 12, and one end of the conductor 2203 is fixedly connected to a micro rectifier 2205, and one end of the conductor 2203 is fixedly connected to the input end of the micro rectifier 2205. The top of the support plate 2202 is fixedly connected to a plurality of embedded cylinders 2213, and the embedded cylinders 2213 correspond to the conductors 2203 one by one, and the embedded cylinders 2 Two conductive sheets 2218 are fixedly connected to the inner wall of 213, the output end of the micro rectifier 2205 is electrically connected to one of the conductive sheets 2218 through a wire, and the other conductive sheet 2218 is electrically connected to the negative end of the generator body 1 through a wire, and a detection bottle 2206 is in contact between the two conductive sheets 2218; by setting the current detection unit 22, the current leaked from the generator body 1 can be introduced into the detection bottle 2206, and the oxygen in the baking soda aqueous solution in the detection bottle 2206 can be ionized, and the ionized oxygen oxidizes the vitamin C powder. By observing the color of the vitamin C powder, it can be known whether the shell of the generator body 1 is leaking, and by observing the oxidation degree of the vitamin C powder, the approximate location of the leakage can be known, so that the leakage situation can be known in time, which is convenient for maintenance personnel to inspect the generator body 1 in time, reduces the risk of accidents, and ensures the personal safety of workers.

[0041] The detection bottle 2206 includes a bottle body 2207, the inner wall of the bottle body 2207 is fixedly connected with a positive electrode rod 2208 and a negative electrode rod 2219, both of which are made of graphite material, and the positive electrode rod 2208 and the negative electrode rod 2219 are electrically connected to two conductive sheets 2218 respectively, the bottle body 2207 is made of transparent glass material, the inner cavity of the bottle body 2207 is fixedly connected with an observation bottle 2209, the observation bottle 2209 is made of brown glass material, and white vitamin C powder is placed in the inner cavity of the observation bottle 2209, the inner cavity of the observation bottle 2209 is fixedly connected with a ventilation pipe 2210, one end of the ventilation pipe 2210 is connected with the inner cavity of the bottle body 2207, the top of the observation bottle 2209 is fixedly connected with a one-way valve 2211, and the ventilation pipe 2210 is located at the observation bottle 220 The inner wall at one end of the bottle 2207 is fixedly connected with a breathable and hydrophobic membrane 2212, the inner cavity of the bottle body 2207 is perfused with a baking soda aqueous solution, and the inner cavities of the bottle body 2207 and the observation bottle 2209 are both perfused with carbon dioxide gas; by setting the bottle body 2207, the positive electrode rod 2208, the negative electrode rod 2219, the observation bottle 2209, the vent pipe 2210, the one-way valve 2211 and the breathable and hydrophobic membrane 2212, the current leaked from the generator body 1 can be diverted to the detection bottle 2206, and the baking soda aqueous solution in the bottle body 2207 is used to ionize oxygen, and the vitamin C powder in the observation bottle 2209 is oxidized by the ionized oxygen. According to the color of the vitamin C powder, it can be determined whether the generator body 1 has leakage, so that the maintenance personnel can know the leakage of the generator body 1 in time.

[0042] Two L-shaped grooves 2214 are provided on the inner wall of the embedding tube 2213, and two embedding blocks 2215 are fixedly connected to the surface of the bottle body 2207, and the surface of the embedding block 2215 is in contact with the inner cavity of the L-shaped groove 2214; by setting the L-shaped groove 2214 and the embedding block 2215 for use in coordination, it is possible to limit the detection bottle 2206 after it is embedded in the embedding tube 2213, thereby ensuring the stability of the detection bottle 2206 after installation.

[0043] A rotating column 2216 is fixedly connected to the top of the observation bottle 2209, and a light-shielding cover 2217 is rotatably connected to the surface of the rotating column 2216 via a damping bearing. A transparent glass area smaller than the light-shielding cover 2217 is provided on the top of the observation bottle 2209; by setting the rotating column 2216 and the light-shielding cover 2217 for use in conjunction, the transparent glass area on the top of the observation bottle 2209 can be shielded from light, and external light is prevented from directly shining on the vitamin C powder and causing the vitamin C powder to be oxidized, thereby ensuring the accuracy of the leakage detection result. The damping bearing can achieve temporary limiting of the rotation angle of the light-shielding cover 2217, and the light-shielding cover 2217 will not rotate when no external rotational force is involved.

[0044] The specific implementation of this embodiment is as follows: if the shell of the generator body 1 has leakage, when the leakage current is transmitted to the shell of the generator body 1, the leakage current will be transmitted to the conductor 2203 through the nearest guide plate 2204, and the conductor 2203 will transmit the current to the micro rectifier 2205. The micro rectifier 2205 here adopts an IGBT rectifier module to integrate the leakage current of the generator body 1 into direct current, and then enter the conductive sheet 2218 through the wire. The conductive sheet 2218 adopts a copper substrate layer and is made of a material with a nickel-plated steel composite on the surface. This material combines the good conductivity of copper and the strength of steel. By plating a layer of nickel on the copper substrate, it not only ensures good conductivity, but also improves the durability and resistance of the metal sheet. Corrosiveness. Under normal working conditions, the user embeds the detection bottle 2206 into the L-shaped groove 2214 through the embedding block 2215, and rotates the detection bottle 2206 horizontally to make the embedding block 2215 contact the inner wall of the L-shaped groove 2214. At this time, the positive rod 2208 and the negative rod 2219 are in close contact with the corresponding conductive sheet 2218 respectively. The conductive sheet 2218 is configured as an elastic sheet to facilitate a closer fit with the positive rod 2208 and the negative rod 2219 to increase conductivity. The current enters the positive rod 2208 through the conductive sheet 2218. According to the principle of electrolysis, an oxidation reaction occurs at the positive rod 2208 to electrolyze the oxygen in the baking soda aqueous solution, and a reduction reaction occurs at the negative rod 2219 to electrolyze hydrogen. The conductive sheet 2218 is attached to the negative rod 2219. The electric sheet 2218 is electrically connected to the negative terminal of the generator body 1 through a wire to ensure that the current forms a closed loop to drive the redox reaction. Since the bottle body 2207 and the observation bottle 2209 are already filled with carbon dioxide gas, when hydrogen and oxygen are produced, the air pressure in the detection bottle 2206 will increase, driving the carbon dioxide gas to be discharged to the outside through the one-way valve 2211. When enough oxygen enters the observation bottle 2209 through the ventilation tube 2210, the vitamin C powder in the observation bottle 2209 is oxidized to change color. The breathable and hydrophobic membrane 2212 in the ventilation tube 2210 can effectively isolate the baking soda solution from entering the observation bottle 2209. In the initial state, the vitamin C powder is white, and it will turn yellow after being oxidized. If it is oxidized too much, it will turn yellow. By observing the color of the vitamin C powder, the leakage situation can be known, and due to the principle of proximity of current conduction, the leakage frequency here can be known according to the oxidation degree of the vitamin C powder, so as to know the approximate leakage position. The observation bottle 2209 is made of brown glass, which can effectively block the direct ultraviolet radiation on the vitamin C powder, thereby avoiding the color change of the vitamin C powder due to light, and improving the accuracy of leakage detection. When the maintenance personnel receive the leakage fault warning and rush to the scene, they can rotate the light shielding cover 2217. The light shielding cover 2217 is rotated by the rotating column 2216 to expose the transparent glass area of ​​the observation bottle 2209. The maintenance personnel can observe the color of the vitamin C powder through the transparent glass area. The detection bottle 2206 is replaceable.During maintenance, maintenance personnel can bring a new test bottle 2206 for replacement, so as to continue to detect leakage.

[0045] A detection method for a safety performance detection device for a mining generator comprises the following steps:

[0046] S1: During installation, the detection bottle 2206 is inserted into the embedding tube 2213, so that the positive electrode rod 2208 contacts the conductive sheet 2218 at the output end of the micro rectifier 2205, the negative electrode rod 2219 contacts another conductive sheet 2218, and the pressure sensor 2108 is connected to the external early warning device;

[0047] S2: The generator body 1 works. When it works for the first time, the cables in the power generation assembly 12 are energized, which interferes with the magnetic field near the cables, causing the magnetic field monitoring unit 21 to generate data. After normal operation, the magnetic field is in a balanced state, and the magnetic field monitoring unit 21 generates constant data. If leakage occurs, the current passing through the cable will decrease, thereby destroying the magnetic field balance and changing the data of the magnetic field monitoring unit 21. The change in data will trigger an external early warning device;

[0048] S3: After receiving the leakage signal, the maintenance personnel inspect the faulty generator by observing the current detection unit 22. The current detection unit 22 conducts the leakage current into the detection bottle 2206, electrolyzes the baking soda aqueous solution in the detection bottle 2206, and produces hydrogen and oxygen. The oxygen oxidizes and discolors the vitamin C powder. If the vitamin C powder is found to turn yellow, it can be determined that there is leakage in the casing of the generator body 1, and by observing the oxidation degree of the vitamin C powder, that is, the color depth, the leakage area can be roughly located.
