Description

Technical Field

[0001] The invention relates to the technical field of electrical equipment protection, and in particular to an embedded multifunctional mining electrical equipment protection device. Background Art

[0002] Mining electrical equipment is a variety of electrical equipment designed for underground conditions in coal mines. Their main function is to meet the electrical needs of coal mining and ensure that the equipment operates safely and efficiently in complex and potentially dangerous environments. Specifically, mining electrical equipment includes two categories: general mining electrical equipment and explosion-proof mining electrical equipment. General mining electrical equipment is mainly used in places without gas and coal dust explosion hazards. They have a sturdy casing to prevent personnel from directly contacting live parts from the outside, and have good sealing, moisture resistance and cable entry devices to ensure the safe operation of the equipment. Mining explosion-proof electrical equipment is suitable for places where explosive mixtures such as gas and coal dust exist. They have taken special explosion-proof measures in design and manufacturing to prevent explosion accidents caused by electric sparks, arcs, etc.

[0003] Existing general electrical equipment for mining, such as oil-immersed power transformers, are generally provided with protective or explosion-proof casings after installation. Although the oil-immersed power transformer can be well protected when installed inside, the oil-immersed power transformer generally conducts heat by itself or by setting up heat dissipation fins. However, the heat will accumulate in the protective box and is difficult to dissipate quickly, which can easily lead to the temperature rise and heat accumulation of the oil-immersed power transformer, resulting in the performance degradation, safety reduction, shortened service life and instability of the power grid. Therefore, we propose an embedded multifunctional protection device for mining electrical equipment. Summary of the invention

[0004] The main purpose of the present invention is to provide an embedded multifunctional mining electrical equipment protection device, which can effectively solve the problem of poor heat dissipation after the transformer is installed.

[0005] To achieve the above object, the technical solution adopted by the present invention is:

The water pump is started by a controller, and the water pump extracts the coolant in the water tank and transports it to the circulating water pipe through the No. 1 connecting pipe. After passing through the circulating water pipe, the coolant flows back to the water tank through the No. 2 connecting pipe, and the circulating water pipe is installed in two groups of heat dissipation fins through the opening, so that the heat on the power transformer and the heat dissipation fins can be quickly taken away, and a cooling plate is also provided on the lower inner wall of the water tank, which can cool the coolant to prevent the coolant from being too high when the temperature is continuously circulated, thereby effectively dissipating the heat of the power transformer.

[0008] Preferably, a door is installed at the front end of the installation box, two installation plates are fixedly installed at the lower left and right ends of the installation box, four No. 1 screws are installed at the upper ends of the installation plates, two installation slots are opened at the left and right ends of the installation box, and filters are fixedly installed in the four installation slots. When the heat emitted by the power transformer through the heat dissipation fins thereon accumulates in the installation box, the temperature sensor can transmit the temperature information to the controller.

[0009] Preferably, a group of heat dissipation fins are installed at the front and rear ends of the power transformer, and through holes are opened at the right ends of the two groups of heat dissipation fins. The left and right parts of the lower end of the power transformer are fixedly installed with mounting frames, and the front and rear parts of the lower ends of the two mounting frames are equipped with universal wheels, and the front and rear parts of the upper ends of the two mounting frames are equipped with No. 2 screws. The design of the universal wheels at the lower ends of the two mounting frames facilitates the short-distance pushing of the power transformer.

[0010] Preferably, the blowing device comprises a connecting plate, a first connecting frame and a second connecting frame are fixedly mounted at the front and rear ends of the connecting plate, respectively, fans are inserted and fixedly mounted at the right ends of the first connecting frame and the second connecting frame, and the connecting plate is fixedly mounted at the middle of the right end of the installation box.

The power transformer pushes the support block into the fixing groove through the universal wheel, and then the No. 2 screw on the mounting frame is screwed into the screw hole, thereby completing the fixing of the power transformer, which is convenient for the rapid installation of the power transformer.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The design of the universal wheels at the lower ends of the two mounting frames facilitates the short-distance pushing of the power transformer. When the power transformer needs to be installed, the power transformer is pushed onto the support block into the fixing groove through the universal wheels, and then the No. 2 screws on the mounting frame are screwed into the screw holes to complete the fixing of the power transformer, which is convenient for the rapid installation of the power transformer. Then, the corresponding installation openings are opened in the mine or on the mine field, and the installation base and the power transformer thereon are embedded and installed in the installation groove to complete the installation of the device.

[0016] 2. The controller is electrically connected to the temperature sensor, water pump, cooling plate and two fans. Therefore, the temperature sensor can detect the temperature in the installation box. When the heat emitted by the power transformer through the heat dissipation fins thereon accumulates in the installation box, the temperature sensor can transmit the temperature information to the controller. When the temperature exceeds the set value, the water pump is started by the controller, and the water pump extracts the coolant in the water tank and transports it to the circulating water pipe through the No. 1 connecting pipe. After passing through the circulating water pipe, the coolant flows back to the water tank through the No. 2 connecting pipe. The circulating water pipe is installed in two sets of heat dissipation fins through the through-hole, so that the heat on the power transformer and the heat dissipation fins can be quickly taken away. In addition, a cooling plate is provided on the lower inner wall of the water tank, which can cool the coolant to prevent the coolant from being too high when the temperature is continuously circulated, thereby effectively dissipating the heat of the power transformer.

[0017] 3. The fan is started through the controller, and the fan blows air into the installation box. The wind blows in through the filter on one side and blows out from the filter on the other side, thereby dissipating the heat of the power transformer. In combination with the water cooling device and the heat dissipation fins of the power transformer, the heat dissipation effect of the device is improved. BRIEF DESCRIPTION OF THE DRAWINGS
