Detailed implementation manner

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0024] Refer to Figures 1-5 , this experimental instrument cleaning device is mainly composed of components such as a hoisting frame 1, a hoisting cylinder 2, a rotating motor 3, a turntable 4, a rotating shaft 5, a wiping sleeve 6, and a water spray pipe 7. Its design purpose is to efficiently clean experimental instruments and achieve comprehensive cleaning of experimental instruments through the coordinated action of mechanical structures.

[0025] The hoisting frame 1 provides a stable support structure for the entire device. The hoisting cylinder 2 and the rotating motor 3 installed above can achieve lifting and rotation control of the components below.

[0026] The hoisting cylinder 2 adjusts the distance between the turntable 4 and the components installed thereon and the experimental instrument to be cleaned through telescopic movement, ensuring that the cleaning operation can be carried out at a suitable position.

[0027] The rotating motor 3 can drive the turntable 4 to rotate, making the cleaning process more comprehensive. The turntable 4, as one of the core components, carries key components such as the water spray pipe 7 and the rotating shaft 5. The hidden motor on the turntable 4 drives the rotating shaft 5 and the water spray pipe 7 to rotate respectively through the rotating mechanism and the transmission mechanism, realizing the coordinated action of wiping and spraying water.

[0028] There are a total of four rotating shafts 5, which are circumferentially and equally spaced on the turntable 4. The wiping sleeves 6 installed on the rotating shafts 5 are used to directly contact the surface of the experimental instrument for physical wiping to remove stains. The wiping sleeves 6 are made of fiber material, having good water absorption and wiping performance. They are installed on the rotating shafts 5 by glue pasting to ensure that they will not fall off during the cleaning process and can stably play the wiping role. Multiple water spray holes 8 are provided on the outer wall of the water spray pipe 7, which can spray water onto the surface of the experimental instrument to wash away stains.

[0029] The water spray pipe 7 is connected to the hidden motor through a transmission mechanism and rotates under the drive of the hidden motor, making the water spraying more uniform. The water spray holes 8 are evenly distributed on the outer wall of the water spray pipe 7 to ensure that the sprayed water flow can cover all parts of the experimental instrument and improve the cleaning effect.

[0030] The hidden motor is installed in the equipment slot of the turntable 4, and drives the rotation of the rotating shaft 5 and the water spray pipe 7 through the rotating mechanism and the transmission mechanism respectively. Two driving gears 10 are installed on the output shaft of the hidden motor, which are respectively meshed with the gears in the rotating mechanism and the transmission mechanism to achieve power transmission.

[0031] The rotating mechanism consists of two driving gears 10, a double-sided gear ring 11 and a transmission gear 12. The driving gear 10 on the output shaft of the hidden motor is meshed with the double-sided gear ring 11, and the double-sided gear ring 11 is also meshed with the transmission gear 12 on the rotating shaft 5, so as to realize the drive of the hidden motor on the rotating shaft 5, and the rotating shaft 5 drives the wiping sleeve 6 to rotate to wipe the experimental instrument.

[0032] The transmission mechanism includes a linkage gear 13 installed on the water spray pipe 7 and a driving gear 10 on the output shaft of the hidden motor. The driving gear 10 is meshed with the linkage gear 13, so that the hidden motor can drive the water spray pipe 7 to rotate and realize the uniform distribution of water spraying.

[0033] The pump water tank 9 is installed on the turntable 4 through the support frame 14, and a rotating cavity 16 and a movable cavity 17 are arranged inside. A reciprocating lead screw 18 is rotatably arranged in the rotating cavity 16, and a piston plate 19 is hermetically and slidably arranged in the movable cavity 17. The pump water tank 9 is connected to the external water source and the water spray pipe 7 through a water suction pipe and a connecting pipe 15 respectively to realize the supply and circulation of water.

[0034] The reciprocating lead screw 18 inside the rotating cavity 16 rotates under the drive of the hidden motor, and drives the piston plate 19 to reciprocate in the movable cavity 17 through the connecting mechanism to realize the pumping of water.

[0035] The piston plate 19 inside the movable cavity 17 reciprocates under the action of the reciprocating lead screw 18, sucks water from the water suction pipe into the movable cavity 17, and then presses it into the water spray pipe 7 through the connecting pipe 15 to realize the circulation and spraying of water.

[0036] The reciprocating lead screw 18 is installed in the rotating cavity 16 and is connected to the output shaft of the hidden motor. The connecting frame 20 sleeved on the reciprocating lead screw 18 through a thread drives the piston plate 19 to reciprocate in the movable cavity 17 to realize the pumping of water.

[0037] The piston plate 19 is hermetically and slidably arranged in the movable cavity 17 and is connected to the reciprocating lead screw 18 through the connecting mechanism. Under the action of the reciprocating lead screw 18, the piston plate 19 reciprocates to realize the suction and discharge of water.

[0038] The connecting mechanism consists of a connecting frame 20 sleeved on the reciprocating lead screw 18 through a thread. The connecting frame 20 is designed in a U shape, and both branches slide through the inner bottom wall of the rotating cavity 16 and extend into the movable cavity 17 and are fixedly connected to the piston plate 19. Under the rotation of the reciprocating lead screw 18, the connecting frame 20 drives the piston plate 19 to reciprocate.

[0039] One end of the water suction pipe is connected to the water pump, and the other end is connected to the movable chamber 17 of the pump water tank 9. A first valve is provided inside the water suction pipe to control the inflow of water. The connecting pipe 15 slides through the outer wall of the water spray pipe 7 and extends into the water spray pipe 7 to transport the water in the pump water tank 9 into the water spray pipe 7. A second valve is provided inside the connecting pipe 15 to control the outflow of water.

[0040] The support frame 14 is used to install the pump water tank 9 on the turntable 4 to ensure the stability of the pump water tank 9.

[0041] When the present utility model is in use, when cleaning experimental instruments, first, the height of the turntable 4 is adjusted by the hoisting cylinder 2 to drive the wiping sleeve 6 into the experimental instrument (inside the beaker). Then, the rotation motor 3 is started to drive the turntable 4 to rotate, and at the same time, the hidden motor is started. The hidden motor drives the rotation of the rotating shaft 5 through the rotating mechanism, driving the wiping sleeve 6 to wipe the experimental instrument (beaker). At the same time, the hidden motor drives the rotation of the water spray pipe 7 through the transmission mechanism, so that the water flow ejected from the water spray holes 8 evenly covers the experimental instrument (beaker). The hidden motor also drives the reciprocating lead screw 18 to rotate, driving the piston plate 19 to reciprocate in the movable chamber 17 through the connecting mechanism, sucking water from the water suction pipe into the movable chamber 17, and then pressing it into the water spray pipe 7 through the connecting pipe 15, and finally ejecting it through the water spray holes 8 to cooperate with the wiping sleeve 6 to ensure the wiping and cleaning effect.

[0042] The above is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, making equivalent replacements or changes should be covered within the protection scope of the present utility model.
