Description

Technical Field

[0001] This utility model relates to the field of hydrogen storage alloy tank technology, and in particular to a spraying machine for applying anti-corrosion coating to hydrogen storage alloy tank bodies. Background Technology

[0002] In today's energy sector, hydrogen, as a clean and efficient energy carrier, makes the development of its storage and transportation technologies crucial. Hydrogen storage alloy tanks, as key equipment for storing hydrogen, play a central role in various hydrogen energy applications. To ensure the lifespan of these tanks, an anti-corrosion coating needs to be applied to their surface. Traditional spraying processes often suffer from uneven coating thickness due to the difficulty in precisely controlling the spray gun's movement speed and paint supply. Excessively thick coatings in some areas not only waste paint but may also affect the adhesion between the coating and the tank; while excessively thin coatings in other areas fail to provide sufficient corrosion protection. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a hydrogen storage alloy tank anti-corrosion coating spraying machine.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A corrosion-resistant coating spraying machine for hydrogen storage alloy tanks includes a placement platform on which a hydrogen storage alloy tank is movably placed. A base is fixedly installed at the bottom of the placement platform, and a rotating ring is rotatably sleeved on the base. An adjusting rod is connected to the outer wall of the rotating ring, and the adjusting rod is connected to a moving trolley. A storage tank and a vertical plate are fixedly installed on the moving trolley, and multiple spray nozzles are fixedly installed on the vertical plate. A drive mechanism is installed on the moving trolley, and the drive mechanism is connected to the storage tank and the spray nozzles.

[0006] Preferably, the placement platform has multiple insertion holes, which are evenly distributed along the circumference of the placement platform. A positioning rod is movably inserted into each insertion hole, and the top of the positioning rod is a hemispherical structure.

[0007] Preferably, the adjusting rod includes a connecting cylinder, one end of which is fixedly connected to a rotating ring, and the other end face of which is fixedly installed with a clamping ring. A connecting rod is slidably sleeved inside the connecting cylinder, and the connecting rod slidably passes through the clamping ring and is fixedly connected to a moving vehicle. The clamping ring has multiple notches, and a locking sleeve is movably sleeved on the connecting rod. The locking sleeve is threaded onto the clamping ring.

[0008] Preferably, the inner diameter of the clamping ring is equal to the diameter of the connecting rod, the outer wall of the clamping ring and the inner wall of the locking sleeve are both frustum structures, and the small diameter end of the frustum structure faces the moving vehicle, and the clamping ring is an elastic stainless steel structure.

[0009] Preferably, a motor is fixedly installed on the top of the mobile vehicle. The output shaft of the motor is connected to the wheel axle of the mobile vehicle via a transmission belt and a transmission wheel. A sliding frame is slidably engaged on the top of the mobile vehicle. Racks are fixedly installed on the top and bottom of the inner cavity of the sliding frame. A half gear is fixedly sleeved on the output shaft of the motor, and the half gear meshes with the rack. A fixed cylinder is fixedly installed on the mobile vehicle. A piston is slidably sleeved inside the fixed cylinder. A sliding rod passes through the piston and the fixed cylinder. One end of the sliding rod is fixedly connected to the sliding frame. Both ends of the fixed cylinder are threaded with a suction pipe and a discharge pipe. The suction pipe is connected to a storage tank, and the discharge pipe is connected to a nozzle.

[0010] Preferably, the bottom of the sliding frame has a T-shaped structure, the top of the moving vehicle has a groove for the T-shaped structure at the bottom of the sliding frame, and a one-way valve is installed in both the suction pipe and the discharge pipe.

[0011] The corrosion-resistant coating spraying machine for hydrogen storage alloy tanks proposed in this utility model has the following advantages:

[0012] 1. A positioning rod is movably inserted into the socket. The top of the positioning rod is a hemispherical structure. The positioning rod is used for three-point positioning, so that the hydrogen storage alloy tank can be self-centered when it is placed on the placement platform. The axis of the tank coincides with the axis of the placement platform. Loosening the locking sleeve will put the clamping ring in a natural relaxed state, and the connecting rod can slide. After adjustment, the locking sleeve is tightened, and the clamping ring is squeezed by the frustum structure. The clamping ring tightens the connecting rod inward through the notch groove to achieve the purpose of locking. This allows the position of the moving vehicle to be adjusted, thereby achieving the purpose of adjusting the distance between the nozzle and the surface of the tank.

[0013] 2. While the motor drives the mobile vehicle to move, it drives the half gear to rotate continuously. The half gear alternately meshes with two racks, so the sliding frame moves back and forth on the top of the mobile vehicle. The sliding frame drives the piston to move back and forth through the slide rod. The suction pipe sucks the paint into the fixed cylinder and supplies it to the nozzle for spraying through the discharge pipe. This achieves a moderate and constant ratio between the instantaneous supply of paint and the instantaneous speed of the mobile vehicle, thus achieving uniform spraying. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model.

[0020] Reference Figure 1 This application provides a hydrogen storage alloy tank anti-corrosion coating spraying machine, including a placement platform 1 on which a hydrogen storage alloy tank is movably placed. A base 2 is fixedly installed at the bottom of the placement platform 1, and a rotating ring 3 is rotatably sleeved on the base 2. An adjusting rod 4 is connected to the outer wall of the rotating ring 3, and the adjusting rod 4 is connected to a moving cart 5. A storage tank 6 and a vertical plate 7 are fixedly installed on the moving cart 5, and multiple nozzles 8 are fixedly installed on the vertical plate 7. A drive mechanism 9 is installed on the moving cart 5, and the drive mechanism 9 is connected to the storage tank 6 and the nozzles 8. The hydrogen storage alloy tank is placed on the placement platform 1. The length of the adjusting rod 4 is adjusted according to the diameter of the tank to control the distance between the nozzles 8 and the surface of the tank. When the moving cart 5 moves, it can only move in a circle due to the limitation of the adjusting rod 4 and the rotating ring 3. The paint is drawn from the storage tank 6 and supplied to the nozzles 8 for spraying by the drive mechanism 9, so that the movement of the moving cart 5 is linked with the paint supply, so that the spraying amount is the same at a certain distance, thereby achieving uniform spraying.

[0021] Reference Figure 1The placement platform 1 has multiple insertion holes 10, which are evenly distributed along the circumference of the placement platform 1. A positioning rod 11 is movably inserted into the insertion hole 10. The top of the positioning rod 11 is a hemispherical structure. The positioning rod 11 is used for three-point positioning, so that the hydrogen storage alloy tank can be self-centered when placed on the placement platform 1. The axis of the tank coincides with the axis of the placement platform 1, ensuring that the spraying distance on the surface of the tank is the same. After the tank is placed, the positioning rod 11 is pulled out to avoid obstructing the paint.

[0022] Reference Figure 1 and Figure 2 The adjusting rod 4 includes a connecting cylinder 41. One end of the connecting cylinder 41 is fixedly connected to a rotating ring 3, and a clamping ring 43 is fixedly installed on the other end face of the connecting cylinder 41. A connecting rod 42 is slidably sleeved inside the connecting cylinder 41. The connecting rod 42 slides through the clamping ring 43 and is fixedly connected to the moving carriage 5. The clamping ring 43 has multiple notches 44. A locking sleeve 45 is movably sleeved on the connecting rod 42. The locking sleeve 45 is threaded onto the clamping ring 43. The inner diameter of the clamping ring 43 is equal to the diameter of the connecting rod 42. Both the outer wall of 3 and the inner wall of the locking sleeve 45 are frustum structures, with the small diameter end of the frustum structure facing the moving vehicle 5. The clamping ring 43 is made of elastic stainless steel. When the locking sleeve 45 is loosened, the clamping ring 43 is in a naturally relaxed state, and the connecting rod 42 can slide, thereby adjusting the position of the moving vehicle 5 to adjust the distance between the nozzle 8 and the surface of the tank. After adjustment, the locking sleeve 45 is tightened, and the clamping ring 43 is squeezed by the frustum structure. The clamping ring 43 tightens the connecting rod 42 inward through the notch 44 to achieve the locking purpose.

[0023] Reference Figure 1 and Figure 3A motor 12 is fixedly installed on the top of the mobile vehicle 5. The output shaft of the motor 12 is connected to the wheel axle of the mobile vehicle 5 via a transmission belt and a transmission wheel. A sliding frame 91 is slidably engaged on the top of the mobile vehicle 5. A rack 92 is fixedly installed on the top and bottom of the inner cavity of the sliding frame 91. A half gear 93 is fixedly sleeved on the output shaft of the motor 12, and the half gear 93 meshes with the rack 92. A fixed cylinder 94 is fixedly installed on the mobile vehicle 5. A piston 95 is slidably sleeved inside the fixed cylinder 94. A sliding rod 96 passes through the piston 95 and the fixed cylinder 94. One end of the sliding rod 96 is fixedly connected to the sliding frame 91. Both ends of the fixed cylinder 94 are threadedly sleeved with a suction pipe 97 and a discharge pipe 98. The suction pipe 97 is connected to... The material storage tank 6 is connected to the discharge pipe 98, which is connected to the nozzle 8. The bottom of the sliding frame 91 has a T-shaped structure, and the top of the moving vehicle 5 has a groove for the T-shaped structure at the bottom of the sliding frame 91. Both the suction pipe 97 and the discharge pipe 98 are equipped with one-way valves. The motor 12 drives the moving vehicle 5 to move while driving the half gear 93 to rotate continuously. The half gear 93 alternately meshes with two racks 92, so the sliding frame 91 moves back and forth on the top of the moving vehicle 5. The sliding frame 91 drives the piston 95 to move back and forth through the slide rod 96. The suction pipe 97 sucks the paint into the fixed cylinder 94 and supplies it to the nozzle 8 for spraying through the discharge pipe 98. This achieves a moderate and constant ratio between the instantaneous supply of paint and the instantaneous speed of the moving vehicle 5, thus achieving uniform spraying.

[0024] Furthermore, both the suction pipe 97 and the discharge pipe 98 are threaded, allowing for the disassembly and cleaning of components such as the fixed cylinder 94.

[0025] Working principle: A positioning rod 11 is movably inserted into the insertion hole 10. The top of the positioning rod 11 is a hemispherical structure. The positioning rod 11 provides three-point positioning, allowing the hydrogen storage alloy tank to self-center when placed on the placement platform 1. The axis of the tank coincides with the axis of the placement platform 1. Loosening the locking sleeve 45 allows the clamping ring 43 to be in a naturally relaxed state, and the connecting rod 42 can slide. After adjustment, the locking sleeve 45 is tightened, and the clamping ring 43 is compressed by the frustum structure. The clamping ring 43 tightens the connecting rod 42 inward through the notch 44, achieving the locking purpose. This adjusts the position of the moving vehicle 5 to achieve the desired spraying. The distance between the nozzle 8 and the surface of the tank is adjusted to ensure that the spraying area of ​​the nozzle 8 is in line with the height of the filling tank. The motor 12 drives the moving vehicle 5 to move while driving the half gear 93 to rotate continuously. The half gear 93 alternately meshes with two racks 92, so the sliding frame 91 moves back and forth on the top of the moving vehicle 5. The sliding frame 91 drives the piston 95 to move back and forth through the slide rod 96. The suction pipe 97 sucks the paint into the fixed cylinder 94 and supplies it to the nozzle 8 for spraying through the discharge pipe 98. The instantaneous supply of paint is in a moderate and constant ratio with the instantaneous speed of the moving vehicle 5 to achieve uniform spraying.
