[0030] See also Figures 1 to 6 This embodiment provides a portable sprayer for cleaning an offshore platform, comprising:

[0031] The back frame 1 includes a back plate 11, an equipment compartment 14 is provided below the back plate 11, a plurality of medicine barrels 2 are provided behind the back plate 11, and a power device 3 is provided in the equipment compartment 14. A pair of shoulder straps 15 are symmetrically provided in front of the back plate 11, a fixing ring 12 is provided at the top of the back of the back plate 11, and a support plate 13 is provided at the bottom of the back plate 11.

[0032] The equipment compartment 14 is fixedly mounted on the bottom of the support plate 13 by means of a clamping connection. The back plate 11, the fixing ring 12 and the support plate 13 are integrally formed of plastic material. The top surface of the support plate 13 is provided with three grooves.

[0033] The medicine barrel 2 is used to hold the cleaning liquid medicine, and the medicine barrel 2 is detachable from the back frame 1. The medicine barrel 2 is located above the support plate 13 and inside the fixing ring 12. The medicine barrel 2 includes a barrel body 21, a barrel cover 22 is provided on the top of the barrel body 21, a one-way valve 23 and a check valve 25 are symmetrically provided on the barrel cover 22, a liquid drawing pipe 24 is provided at the bottom of the check valve 25, and the top of the check valve 25 is connected to the driving device through a pipeline.

[0034] The barrel body 21 and the barrel cover 22 are both made of plastic material, and the barrel body 21 and the barrel cover 22 are threadedly connected. The barrel body 21 is cylindrical, and the barrel body 21 is inserted from the top of the fixing ring 12, and the bottom of the barrel body 21 is inserted into the groove on the support plate 13 and is clamped with the support plate 13.

[0035] The one-way valve 23 and the check valve 25 are threadedly connected to the barrel cover 22. The one-way valve 23 is used for outside air to enter the barrel cover 22, and the check valve 25 is used to prevent the liquid medicine from flowing back.

[0036] The liquid drawing tube 24 passes through the barrel cover 22 and extends into the barrel body 21 . The bottom end of the liquid drawing tube 24 abuts against the inner bottom surface of the barrel body 21 , and the bottom end of the liquid drawing tube 24 is a pointed end.

[0037] The liquid drawing pipe 24 is made of a rubber hose, and the head of the liquid drawing pipe 24 is clamped with the check valve 25.

[0038] The power device 3 includes a driving device, which is used to draw liquid medicine from the medicine barrel 2. The driving device is connected to a control device through a pipeline, and the control device is used to control the start and stop of the driving device and spray the liquid medicine.

[0039] The driving device is installed in the equipment compartment 14.

[0040] The driving device comprises a driving motor 33 , which is connected to a spray pump 35 via a gear box 34 , a manifold 32 is provided at a liquid inlet of the spray pump 35 , and the manifold 32 is connected to the check valve 25 via a pipeline.

[0041] The driving motor 33 is a 24V DC motor, the gear box 34 is a known reduction gear box, the output shaft of the driving motor 33 and the input shaft of the spray pump 35 are connected to the gear box 34, and the spray pump 35 is a gear pump.

[0042] After the driving motor 33 is started, the output shaft of the driving motor 33 can drive the input shaft of the spray pump 35 to rotate through the gear box 34 , thereby driving the spray pump 35 to work and generating negative pressure at the liquid inlet of the spray pump 35 .

[0043] The manifold 32 is threadedly connected to the liquid inlet of the spray pump 35. After the liquid inlet of the spray pump 35 generates negative pressure, the negative pressure can be transmitted to the manifold 32, and then transmitted to the check valve 25 through the pipeline, so that the liquid medicine is drawn into the barrel body 21 through the liquid drawing pipe 24, and at the same time, air enters the barrel body 21 through the check valve 23. The drawn liquid medicine is pumped out from the liquid discharge port of the spray pump 35.

[0044] The driving device also includes a battery pack 31 , which is located in the center of the equipment compartment 14 . The battery pack 31 is used to supply power to the driving motor 33 .

[0045] The battery pack 31 is a lithium battery, which is connected to the driving motor 33 via a wire and can be charged and used repeatedly.

[0046] The control device includes a spray handle 37, on which a spray switch 38 is fixedly installed by screws. The spray switch 38 is connected to the drive motor 33 by a wire and is used to control the start and stop of the drive motor 33. The front end of the spray handle 37 is screwed with a spray pipe 39. The tail end of the spray handle 37 is connected to a safety valve 36 through a pipeline, and the safety valve 36 is connected to the liquid outlet of the spray pump 35 through a pipeline. The safety valve 36 is used to prevent the spray switch 38 from being accidentally touched.

[0047] The liquid medicine pumped out of the discharge port of the spray pump 35 enters the safety valve 36 from the pipeline, passes through the safety valve 36, enters the spray handle 37 through the pipeline, and then is sprayed out from the top of the spray pipe 39.

[0048] The safety valve 36 is connected to the spray switch 38 and the battery pack 31 through a wire. After the safety valve 36 is closed, the spray switch 38 loses its function. When the device is not in use, the safety valve 36 is closed to prevent the spray switch 38 from being accidentally touched.

[0049] When using the device, fill the barrel body 21 with liquid medicine, tighten the barrel cover 22, insert the medicine barrel 2 from above the fixing ring 12, and insert the bottom of the barrel body 21 into the groove on the support plate 13 and engage with the support plate 13.

[0050] The check valve 25 is connected to the manifold 32 by a pipeline.

[0051] The user uses the shoulder strap 15 to carry the backpack 1 equipped with the medicine barrel 2 on his back, and holds the spray handle 37 in his right hand.

[0052] First open the safety valve 36, then aim the spray tube 39 at the position to be sprayed, press the spray switch 38 with your finger, start the drive motor 33, and the drive motor 33 drives the spray pump 35 to work, sucking the liquid out of the barrel 21, and then pumping it out from the liquid outlet of the spray pump 35, passing through the safety valve 36 and the spray handle 37, and finally spraying it out from the spray tube 39

[0053] After the liquid medicine is used up, a new medicine barrel 2 can be replaced to continue spraying.

[0054] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention.
