Description

Technical Field

[0001] This invention belongs to the technical field of diesel generator set supporting equipment, specifically a diesel generator set descaling device. Background Technology

[0002] Diesel generator sets serve as core power sources in mining, construction sites, and emergency power supply scenarios. The cleanliness of their fuel tanks directly determines the stability of fuel supply and the lifespan of the generator set. During long-term use, the gum and asphaltenes in the diesel fuel oxidize and polymerize under high temperatures. These mix with metal shavings from engine wear, dust from the air, and moisture that seeps in during fuel storage, forming sludge of varying viscosity. Specifically, this manifests as a mixture of particulate deposits at the bottom, a gelatinous sludge adhering to the inner walls, and emulsified sludge formed by moisture and impurities. If this sludge is not cleaned regularly, it will clog the fuel filter and fuel injectors, leading to decreased fuel pressure and poor atomization. This not only reduces generator power and increases fuel consumption but also accelerates fuel pump wear. In extreme cases, it can cause generator shutdown or component failure, increasing maintenance costs and safety risks.

[0003] Currently, the mainstream descaling method mainly involves using descaling machines for cleaning. However, during operation, it is necessary to manually insert the cleaning head into the oil tank. While cleaning, the hand needs to hold the cleaning head and constantly change its position and height to change the position of the cleaning head inside the oil tank in order to achieve the cleaning purpose. The descaling equipment lacks a fixed measure to the oil tank, making the operation quite laborious. Summary of the Invention

[0004] This invention provides a descaling device for diesel generator sets, which can solve the technical problem that existing descaling devices for diesel generator sets require manual hand-held operation, which is quite laborious.

[0005] A descaling device for a diesel generator set includes a positioning mechanism, wherein a fixing mechanism is fixedly connected to both sides of the positioning mechanism, and a descaling mechanism is engaged inside the positioning mechanism. The positioning mechanism includes a fixed base, a ball seat is snapped onto the top of the fixed base, and a universal ball is rotatably installed inside the ball seat. The descaling mechanism is snapped into the universal ball, and several snapping components are fixedly connected between the outside of the ball seat and the top wall of the fixed base.

[0006] As a further technical solution of the present invention, the snap-fit ​​assembly includes a snap-fit ​​cylinder, a sleeve rod snap-fitted inside the snap-fit ​​cylinder, a horizontal plate fixedly connected to the top end of the sleeve rod, an extension plate fixedly connected to the outside of the snap-fit ​​cylinder, and a fixing bolt threadedly connected through the extension plate and the outer wall of the snap-fit ​​cylinder and the sleeve rod.

[0007] As a further technical solution of the present invention, the bottom wall of the snap-fit ​​cylinder is fixedly connected to the top surface of the fixed seat, the end of the horizontal plate away from the sleeve rod is fixedly connected to the outer wall of the ball seat, and threaded holes adapted to the fixing bolts are opened through the outer walls of the snap-fit ​​cylinder and the sleeve rod.

[0008] As a further technical solution of the present invention, the bottom of the fixed base is provided with two storage grooves, and both ends of the storage grooves are rotatably mounted with stable feet. The stable feet include a damping shaft rotatably connected to the storage grooves, a sleeve is fixedly connected to the outside of the damping shaft, a support screw is threadedly connected to the inside of the sleeve, and a suction cup is movably connected to the end of the support screw away from the sleeve through a rotating shaft.

[0009] As a further technical solution of the present invention, the inner wall of the sleeve is provided with an internal thread, the supporting screw is adapted to the internal thread, and the suction cup is made of rubber.

[0010] As a further technical solution of the present invention, a movable groove is provided in the center of the fixed base, and a rubber ring is installed at the bottom of the movable groove, and the ball seat is engaged in the movable groove.

[0011] As a further technical solution of the present invention, the fixing mechanism includes a sleeve plate, and a sliding plate is slidably installed inside the sleeve plate. A vertical plate is fixedly installed on the top of the sleeve plate. An adjusting screw is threaded through the inner side of the vertical plate. Two guide rods are also slidably installed through the inner side of the vertical plate. The two guide rods are located on both sides of the adjusting screw. A connecting plate is fixedly installed on the top surface of the end of the sliding plate away from the vertical plate. The end of the guide rod away from the vertical plate is fixedly connected to the connecting plate. The end of the adjusting screw away from the vertical plate is rotatably connected to the connecting plate. A clamping plate is fixedly installed on the bottom surface of the end of the sliding plate away from the vertical plate. Several rubber pads are fixedly installed on the side of the clamping plate.

[0012] As a further technical solution of the present invention, a plane bearing is fixedly installed on the side wall of the connecting plate, and the end of the adjusting screw away from the vertical plate is fixedly connected to the shaft hole of the bearing. A guide groove is provided on the vertical plate, and the guide rod is slidably connected to the guide groove.

[0013] As a further technical solution of the present invention, the descaling mechanism includes a fixed plate, a connecting pipe is fixedly installed through the fixed plate, and a corrugated pipe section is fixedly connected to the bottom end of the connecting pipe. A spray plate is fixedly connected to the bottom end of the corrugated pipe section. An electric push rod is fixedly connected between the bottom surface of the fixed plate and the top wall of the spray plate. Several nozzles are installed in a ring around the outer periphery of the spray plate, and a negative pressure suction head is fixedly connected to the bottom of the spray plate.

[0014] As a further technical solution of the present invention, the connecting pipe is snapped into the universal ball, and a negative pressure pipe is provided inside the connecting pipe. The negative pressure pipe enters the connecting pipe and connects with the negative pressure suction head. A conveying pipe is installed on the top of the connecting pipe, and the conveying pipe is interconnected with the connecting pipe and the spray plate.

[0015] The beneficial effects of this invention are as follows: By setting up a fixing mechanism, the fuel tank of the diesel generator set can be clamped and fixed using two fixing mechanisms. By rotating the adjusting screw to drive the connecting plate to move laterally, the total length of the sleeve plate and the sliding plate can be adjusted, thereby adapting to fuel tanks of different lateral lengths. The two fixing mechanisms can be adjusted to different lengths, thus adapting to the fixing of fuel tanks with the fuel tank cover in the middle or on the side. The fixing operation can be achieved by using the clamping plate to clamp the side wall of the fuel tank. It is not only suitable for fixing cylindrical fuel tanks, but also for fixing rectangular fuel tanks. By setting up a positioning mechanism, the descaling mechanism is positioned and kept in the oil tank cover installation area. A stable support foot is set at the bottom of the fixed base, which can be extended by rotating the support screw. It can be used with the suction cup to adhere and fix to the outer wall of the oil tank, thus ensuring the support stability of the fixed base. The suction cup is connected by a rotating shaft and can be moved. It can also be used to adhere and fix to the surface of cylindrical oil tanks. During descaling, simply swing the connecting pipe and use the rotation of the universal ball to adjust the position of the nozzle and the negative pressure suction head inside the oil tank. This eliminates the need for continuous manual cleaning and makes the descaling equipment more labor-saving. It is also equipped with an electric push rod and a corrugated pipe section. As the connecting pipe swings, the electric push rod can drive the corrugated pipe section to extend and retract, which can compensate for the height change of the negative pressure suction head. This effectively absorbs oil sludge from various areas of the bottom wall of the oil tank and solves the problem that manual manual cleaning requires not only holding the device but also moving the hand up and down to adjust the height. Furthermore, by setting up a snap-fit ​​assembly, after the snap-fit ​​cylinder and the sleeve rod snap together, they can be fixed with fixing bolts to fix the ball seat on the upper part of the fixed seat. After removing the fixing bolts, the snap-fit ​​cylinder and the sleeve rod can be separated, and the ball seat can be detached from the fixed seat. At this time, the descaling mechanism can be easily pulled out from the oil tank, which is convenient for cleaning the nozzle, the negative pressure suction head, and the surface of the connecting pipe.

[0019] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] like Figures 1-7 As shown, a descaling device for a diesel generator set includes a positioning mechanism 1, with fixing mechanisms 2 fixedly connected to both sides of the positioning mechanism 1, and a descaling mechanism 3 being snapped into the positioning mechanism 1. The positioning mechanism 1 includes a fixed base 11, a ball seat 13 is snapped onto the top of the fixed base 11, and a universal ball 14 is rotatably installed inside the ball seat 13. The descaling mechanism 3 is snapped into the universal ball 14, and several snap-fit ​​components 15 are fixedly connected between the outside of the ball seat 13 and the top wall of the fixed base 11.

[0021] Specifically, the descaling mechanism 3 is fixed by the ball seat 13, so that the angle of the descaling mechanism 3 can be changed by rotating the ball seat 13 during manual operation, which is more labor-saving than hand operation.

[0022] The snap-fit ​​assembly 15 includes a snap-fit ​​cylinder 151, a sleeve rod 153 is snapped into the snap-fit ​​cylinder 151, a horizontal plate 154 is fixedly connected to the top of the sleeve rod 153, an extension plate 152 is fixedly connected to the outside of the snap-fit ​​cylinder 151, and a fixing bolt 155 is threadedly connected through the extension plate 152, the outer wall of the snap-fit ​​cylinder 151 and the sleeve rod 153. The bottom wall of the snap-fit ​​cylinder 151 is fixedly connected to the top surface of the fixing seat 11. The end of the horizontal plate 154 away from the sleeve rod 153 is fixedly connected to the outer wall of the ball seat 13. Threaded holes adapted to the fixing bolts 155 are opened through the outer walls of the snap-fit ​​cylinder 151 and the sleeve rod 153.

[0023] Specifically, after the snap-fit ​​cylinder 151 and the sleeve rod 153 are snapped together, they are fixed with the fixing bolt 155, which can fix the ball seat 13 on the upper part of the fixing seat 11. After the fixing bolt 155 is removed, the snap-fit ​​cylinder 151 and the sleeve rod 153 can be separated, and the ball seat 13 can be separated from the fixing seat 11. At this time, the descaling mechanism 3 can be easily pulled out from the inside of the oil tank.

[0024] The bottom of the fixed base 11 has two storage grooves 12, and both ends of the storage grooves 12 are rotatably mounted with stable feet 17. The stable feet 17 include a damping shaft 171 rotatably connected to the storage grooves 12. A sleeve 172 is fixedly connected to the outside of the damping shaft 171. A support screw 173 is threadedly connected to the sleeve 172. The end of the support screw 173 away from the sleeve 172 is movably connected to a suction cup 174 through a rotating shaft. The inner wall of the sleeve 172 is provided with an internal thread. The support screw 173 is adapted to the internal thread. The suction cup 174 is made of rubber.

[0025] Specifically, the rotation of the support screw 173 can adjust its overall length. At this time, it can be attached to the fuel tank cap installation area of ​​the fuel tank by suction cup 174, thereby improving the stability of the mounting base 11 during installation.

[0026] A movable groove 16 is provided in the center of the fixed base 11, and a rubber ring is installed at the bottom of the movable groove 16. The ball seat 13 is engaged in the movable groove 16. By setting the rubber ring, the connecting pipe 32 is prevented from being damaged by collision when rotating, thus effectively protecting it.

[0027] The fixing mechanism 2 includes a socket plate 21, and a sliding plate 22 is slidably installed inside the socket plate 21. A vertical plate 23 is fixedly installed on the top of the socket plate 21. An adjusting screw 24 is threaded through the inner side of the vertical plate 23. Two guide rods 25 are also slidably installed through the inner side of the vertical plate 23. The two guide rods 25 are located on both sides of the adjusting screw 24. A connecting plate 26 is fixedly installed on the top surface of the end of the sliding plate 22 away from the vertical plate 23. The end of the guide rod 25 away from the vertical plate 23 is fixedly connected to the connecting plate 26. The end of the adjusting screw 24 away from the vertical plate 23 is rotatably connected to the connecting plate 26. A clamping plate 27 is fixedly installed on the bottom surface of the end of the sliding plate 22 away from the vertical plate 23. Several rubber pads 28 are fixedly installed on the side of the clamping plate 27.

[0028] A plane bearing is fixedly installed on the side wall of the connecting plate 26. The end of the adjusting screw 24 away from the vertical plate 23 is fixedly connected to the shaft hole of the bearing. A guide groove is provided on the vertical plate 23, and the guide rod 25 is slidably connected to the guide groove.

[0029] Specifically, by rotating the adjusting screw 24 to move the connecting plate 26 laterally, the total length of the sleeve plate 21 and the sliding plate 22 can be adjusted, thus adapting to oil tanks of different lateral lengths. Rotating the adjusting screw 24 causes the clamping plate 27 to fit tightly against the side wall of the oil tank, thereby achieving clamping and fixing operations.

[0030] The descaling mechanism 3 includes a fixed plate 31, a connecting pipe 32 is fixedly installed through the fixed plate 31, and a corrugated pipe section 33 is fixedly connected to the bottom end of the connecting pipe 32. A spray plate 35 is fixedly connected to the bottom end of the corrugated pipe section 33. An electric push rod 34 is fixedly connected between the bottom surface of the fixed plate 31 and the top wall of the spray plate 35. Several spray heads 36 are installed in a ring around the outer periphery of the spray plate 35, and a negative pressure suction head 37 is fixedly connected to the bottom of the spray plate 35.

[0031] The connecting pipe 32 is snapped into the universal ball 14, and a negative pressure pipe is provided inside the connecting pipe 32. The negative pressure pipe enters the connecting pipe 32 and connects to the negative pressure suction head 37. A conveying pipe is installed on the top of the connecting pipe 32, and the conveying pipe communicates with the connecting pipe 32 and the spray plate 35.

[0032] Specifically, the degreasing agent is delivered to the inside of the oil tank through the delivery pipe, so that it comes into contact with the sludge and softens it. After the negative pressure suction head 37 is connected to the negative pressure pump, negative pressure is generated through the negative pressure pipe, thereby extracting the softened sludge.

[0033] This invention discloses a descaling device for diesel generator sets. In use, the diesel generator fuel tank cap is removed. First, based on the position of the fuel tank cap, the descaling mechanism 3 is inserted into the fuel tank from the cap's mounting location. Rotating the adjusting screw 24 causes the connecting plate 26 to move laterally, thus adjusting the total length of the sleeve plate 21 and the sliding plate 22 to accommodate fuel tanks of different lateral lengths. Then, rotating the adjusting screw 24 in the opposite direction causes the clamping plate 27 to adhere tightly to the side wall of the fuel tank, thereby achieving clamping and fixing. The two fixing mechanisms 2 can be adjusted to different lengths to accommodate fuel tanks with the cap in the middle or on the side.

[0034] After the fixing mechanism 2 is fixed, the fixing seat 11 is located above the fuel tank cover installation location. The stabilizing support leg 17 is flipped down, and the sleeve 172 is rotated downward to a vertical state through the damping shaft 171. Then the support screw 173 is rotated so that the suction cup 174 at its bottom end contacts the outer top wall of the fuel tank in the fuel tank cover installation area and is attracted and fixed, thus reinforcing and supporting the fixing seat 11.

[0035] During descaling, the degreasing agent is delivered to the inside of the oil tank through the delivery pipe, so that it comes into contact with the sludge and softens it. After the negative pressure suction head 37 is connected to the negative pressure pump, negative pressure is generated through the negative pressure pipe, thereby extracting the softened sludge.

[0036] By swinging the connecting pipe 32 and rotating the universal ball 14 within the ball seat 13, the degreasing agent sprayed from the nozzle 36 outside the spray plate 35 is sprayed onto various areas of the inner wall of the fuel tank. When the negative pressure absorbs the sludge, the swinging connecting pipe 32 drives the negative pressure suction head 37 to absorb the sludge in various areas of the bottom wall of the fuel tank. As the connecting pipe 32 swings, the electric push rod 34 drives the corrugated pipe section 33 to extend and retract, compensating for the height change of the negative pressure suction head 37, thereby effectively absorbing the sludge in various areas of the bottom wall of the fuel tank and realizing the descaling operation of the fuel tank inside the diesel generator set.

[0037] The above description is merely an example and illustration of the structure of the present invention. Those skilled in the art can make various modifications or additions to the specific embodiments described, or use similar methods to replace them, as long as they do not deviate from the structure of the invention or exceed the scope defined in the claims, all of which should fall within the protection scope of the present invention.
