Description

Technical Field

[0001] This utility model belongs to the technical field of coal mine equipment, specifically a cleaning device for the maintenance of coal mine electromechanical equipment. Background Technology

[0002] Axial flow impellers for mining are a type of electromechanical equipment in coal mines. When cleaning them, a spray cleaning system is usually set up, including a water tank, water pump, nozzles and related pipelines. The water pump pressurizes the cleaning fluid in the water tank and sprays it out through the nozzles. The nozzles are generally arranged according to the structure and shape of the impeller to achieve a comprehensive spraying of the impeller surface.

[0003] However, due to the harsh working environment and uneven airflow distribution in coal mines, the distribution of dirt on different blade surfaces and different parts of the same blade of the mining axial flow impeller is significantly different. Some areas have thick dirt accumulation, while other areas have thin dirt. Existing spray cleaning technology is difficult to treat the dirt in a targeted manner based on the uneven characteristics of the dirt, which easily leads to problems such as thick dirt residue and inconsistent cleaning results. Summary of the Invention

[0004] The purpose of this utility model is to provide a cleaning device for the maintenance of coal mine electromechanical equipment, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cleaning device for the maintenance of coal mine electromechanical equipment, comprising a cleaning box, an inner cavity of which is provided with a spray plate, a box cover hinged to the cleaning box, the spray plate being fixedly installed at the bottom of the box cover, a placement plate for placing an impeller being rotatably connected to the inner cavity of the cleaning box, two inclined plates with the same inclination being symmetrically fixedly installed on the placement plate, the distance between the two inclined plates being the same as the diameter of the impeller hub, a first arc-shaped protrusion with the same number of impeller blades being fixedly installed on the outer peripheral wall of the placement plate, a second arc-shaped protrusion abutting against the first arc-shaped protrusion being slidably connected to the inner wall of the cleaning box, and a cleaning roller for cleaning dirt from the blades being provided on the second arc-shaped protrusion, the inclination of the cleaning roller being the same as that of the inclined plate.

[0006] Preferably, a pneumatic motor is fixedly installed at the bottom of the cleaning tank, and the output end of the pneumatic motor is fixedly connected to the placement plate.

[0007] Preferably, the cleaning roller includes a pneumatic motor fixedly connected to the second arc-shaped protrusion, and a rotating drum is fixedly installed at the output end of the pneumatic motor. The outer peripheral wall of the rotating drum is fitted with annular cleaning brushes of the same number as the impellers, and the arrangement angle of the annular cleaning brushes is consistent with the inclination of the inclined plate.

[0008] Preferably, a pair of compression springs are fixedly installed on the inner wall of the cleaning tank, and the side of the compression spring away from the inner wall of the cleaning tank is fixedly connected to the second arc-shaped protrusion.

[0009] Preferably, the front of the cleaning tank is provided with a viewing window.

[0010] Preferably, a discharge pipe is provided at the bottom of one side of the cleaning tank.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. This utility model adopts a technical means of combining a placement plate and a cleaning roller. By rotating the placement plate, the cleaning roller slides intermittently. Workers can observe through the viewing window on the front of the cleaning box whether the impeller has rotated to the area with more serious dirt on the blades. This allows the equipment to selectively clean the impeller according to the specific distribution of dirt, thereby making the impeller cleaner more uniform and improving the overall cleaning efficiency of the equipment.

[0013] 2. This utility model adopts a technical means of combining two inclined plates and a cleaning roller. By stacking at least two mining axial flow impellers between two inclined plates, the two inclined plates not only facilitate the tilting of the impellers, but also facilitate the relative positioning of the impellers when they rotate, so that multiple impellers can be kept in a staggered position during cleaning, thereby improving the overall cleaning efficiency of the equipment and making it convenient to use.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1 to 6 As shown in the figure, this utility model embodiment provides a cleaning device for the maintenance of coal mine electromechanical equipment, including a cleaning box 1. A pair of movable wheels are fixedly installed on both sides of the bottom end of the cleaning box 1. The movable wheels are brake swivel wheels. The movable wheels facilitate the overall movement of the cleaning box 1.

[0026] The front of the cleaning box 1 is equipped with a viewing window made of transparent acrylic, which allows workers to easily observe the cleaning status of the impeller.

[0027] The inner cavity of the cleaning box 1 is equipped with an impeller dirt treatment mechanism. The impeller dirt treatment mechanism includes a placement plate 31 for placing the impeller, which is rotatably connected to the bottom of the inner wall of the cleaning box 1. Two inclined plates 32 with the same inclination are fixedly installed on the placement plate 31. The two inclined plates 32 are arranged in a circular array with the center of the placement plate 31 as the center. The distance between the two inclined plates 32 is the same as the diameter of the impeller hub, so that the impeller hub can be precisely locked between the two inclined plates 32, which plays a role in precise positioning and ensures that the mining axial flow impeller will not shake or deviate on the placement plate 31.

[0028] The inclined plate 32 enables adjacent impellers to be stacked tightly and stably in the vertical direction. Furthermore, by matching the hub with the distance between the two inclined plates 32, the hub of the lower impeller can accurately support the upper impeller, ensuring the stability of the staggered stack and improving space utilization.

[0029] More specifically, the inclination range of the inclined plate 32 is 30°-60°. The specific inclination angle of the inclined plate 32 should be selected according to the actual use requirements. The inclination angle setting should not only ensure the stability of the impeller placement, but also facilitate the installation and removal of the impeller.

[0030] A pneumatic motor 3 is fixedly installed at the bottom of the cleaning tank 1, and the output end of the pneumatic motor 3 is fixedly connected to the placement plate 31.

[0031] A rectangular frame 33 is fixedly installed on the inner wall of the cleaning tank 1. A square through slot for the placement plate 31 to rotate is opened through the inner cavity of the rectangular frame 33. A first arc-shaped protrusion 36 with the same number of impeller blades is fixedly installed on the outer peripheral wall of the placement plate 31. An inner groove 37 is opened in the inner cavity of the rectangular frame 33. A pair of compression springs 38 are fixedly installed on the inner wall of the inner groove 37. A second arc-shaped protrusion 39 that abuts against the first arc-shaped protrusion 36 is slidably connected between the two inner side walls of the inner groove 37. The side of the compression spring 38 away from the inner wall of the inner groove 37 is fixedly connected to the second arc-shaped protrusion 39.

[0032] A cleaning roller is slidably connected to the rectangular frame 33. The cleaning roller includes a pneumatic motor 310 fixedly connected to the second arc-shaped protrusion 39. A rotating drum 34 is fixedly installed at the output end of the pneumatic motor 310. The outer peripheral wall of the rotating drum 34 is fitted with annular cleaning brushes 35, the same number as the impeller. The arrangement angle of the annular cleaning brushes 35 is consistent with the inclination of the inclined plate 32. The height of the annular cleaning brushes 35 is consistent with the height of the blades in the impeller. This not only facilitates cleaning multiple impeller dirt areas, but also facilitates staggering the impeller blades, thereby further ensuring the uniformity of subsequent cleaning of the equipment.

[0033] More specifically, the circular cleaning brush 35 is made of soft and flexible bristles, which helps to reduce the rotational resistance of the cleaning roller.

[0034] Furthermore, the pneumatic motor 310 uses compressed air as its power source and does not generate electrical sparks during operation, thus making it easier for the equipment to adapt to complex working environments.

[0035] A cover 2 is hinged to the top of the cleaning tank 1. A spraying mechanism is provided at the bottom of the cover 2. The spraying mechanism includes a spray plate 21 for cleaning the impeller, which is fixedly installed at the bottom of the cover 2. The spray plate 21 is adapted to the structure and shape of the impeller. A water pipe 22 is fixedly connected to the top of the spray plate 21. The end of the water pipe 22 away from the spray plate 21 passes through the cover 2 and extends to the top of the cover 2. The water pipe 22 is connected to the water tank through an external water pump. The cleaning liquid in the water tank is pressurized by driving the water pump and then sprayed out through the spray plate 21.

[0036] A discharge pipe 311 is provided at the bottom of one side of the cleaning tank 1. The discharge pipe 311 includes a control valve. The control valve is used to control the flow of water in the pipe, the flow rate, the flow direction, and the pressure regulation. After the impeller is cleaned, the worker can operate the control valve to facilitate the recycling of the waste liquid after cleaning.

[0037] Working principle: Move the entire equipment to the designated working location. After arriving at the working location, rotate the cover 2 to expose the opening of the cleaning tank 1. Place at least two impellers on the placement plate 31. The two inclined plates 32 fixedly installed on the placement plate 31 not only facilitate the tilting and stacking of the impellers, but also facilitate the relative positioning of the impellers. After stacking, rotate the cover 2 again to reset it. The closing of the cover 2 prevents secondary contamination of the impellers. Finally, drive the water pump and pneumatic motor 3. The water pump pressurizes the cleaning liquid in the water tank and sprays it out through the spray plate 21, thereby facilitating a comprehensive spraying of the impeller surface. The pneumatic motor 3 drives the impellers on the placement plate 31 to rotate synchronously.

[0038] Since the number of the first arc-shaped protrusions 36 fixed on the outer peripheral wall of the placement plate 31 is the same as the number of impeller blades, the first arc-shaped protrusions 36 intermittently squeeze the second arc-shaped protrusions 39 that are slidably connected to the inner cavity of the rectangular frame 33 by the external rotation of the placement plate 31. The intermittent sliding of the second arc-shaped protrusions 39 drives the cleaning roller to move synchronously. The worker can observe the areas of the impeller blades with more serious dirt through the viewing window on the front of the cleaning box 1. When the placement plate 31 rotates to the area of ​​the blades with more serious dirt, the pneumatic motor 310 is driven. The pneumatic motor 310 facilitates the rotation of the rotating drum 34 during the impeller cleaning process, which drives the annular cleaning brush 35 to further clean the areas of the blades with more serious dirt, thereby ensuring the uniformity of the cleaning of the equipment and making it convenient to use.

[0039] The cleaned liquid enters the bottom of the inner wall of the cleaning tank 1, and the worker can operate the control valve to facilitate the recycling of the cleaned waste liquid through the discharge pipe 311.

[0040] Remove it after cleaning.
