Abstract
Description
Technical Field
[0001] This invention relates to the field of engineering cost technology, and in particular to a method for recording engineering costs. Background Technology
[0002] An existing application (CN210062453U) discloses a method for recording engineering costs, which includes a base plate, a buckle, a movable page, a connecting plate, a pressure block, a positioning rod, a protective plate, recording paper, and a fixing device. This utility model's method for recording engineering costs addresses the problem of unstable pen fixation, leading to pen loss. By incorporating a fixing device, when the pen needs to be fixed, pulling the fixing block moves the second clamping block. The second clamping block slides along a slide rail via a slider, simultaneously pressing against a spring at the upper end of the guide post, causing the spring to contract. The pen is then placed inside the first and second clamping blocks. Releasing the fixing block allows the spring to recover its deformation, causing the second clamping block to clamp the pen. The spring's elastic potential energy secures the pen, achieving stable fixation and preventing loss. Because the handwriting on the recording board needs to be manually cleaned frequently by the operator, and the operator comes into direct contact with chalk dust during the manual cleaning process, which poses a health hazard to the operator, we propose a method for recording engineering costs. Summary of the Invention
[0003] The purpose of this invention is to address the shortcomings of existing technologies where operators need to frequently manually clean the chalk marks on the recording board, which involves direct contact with chalk dust and poses a health hazard to the operators.

[0019] The engineering cost recording method proposed in this invention has the following advantages:
[0020] The device features a cleaning mechanism. It records different types of engineering cost project progress information on the panel. After recording, cotton blocks on the radial plate clean the ink marks on the panel surface. A motor drives an incomplete gear to rotate, which in turn drives a gear to rotate, thereby causing the connecting shaft and the radial plate to rotate synchronously. The cotton blocks come into contact with the ink marks on the panel surface, thus achieving automated cleaning of the ink marks. As a result, the ink marks on the recording board do not need to be manually cleaned by the operator. During the cleaning process, the operator no longer comes into direct contact with chalk dust, thus avoiding any harm to the operator's health.
[0021] During the cleaning process, water is drawn in by the pump and atomized by multiple atomizing nozzles, thus humidifying the surface of the cotton pad and preventing excessive dust accumulation near the pad. An air pump creates negative pressure at the guide channel, drawing in a small amount of dust, which is then discharged to a designated cleaning location. Motor 2 drives the drive wheel, which in turn drives the transmission wheel. This, in conjunction with multiple gears (gears 2 and 3), causes multiple cam columns to rotate synchronously. The cleaning brushes on these cam columns remove dust from the cotton pad surface, further improving the cleaning effect and preventing the accumulation of large amounts of dust.
[0022] The servo motor drives gear four to rotate, and the hydraulic cylinder drives the movable frame to move up and down. Gear four rotates sequentially with driven wheel one and driven wheel two, which in turn drives reciprocating screw one and reciprocating screw two to rotate sequentially. This allows the upper and lower movable seats to move up and down sequentially, enabling the atomizing nozzle to humidify all areas of the cotton block surface. At the same time, the cleaning brush on the cam column can remove dust from different areas of the cotton block surface. Attached Figure Description

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0033] Example 1:
[0034] Reference Figure 1-8 A method for recording engineering costs includes the following steps:
[0035] S1: Real-time monitoring of project cost progress using an engineering cost recording device;
[0036] S2: After observing the progress changes in real time, the observed progress is recorded in a timely manner through the project cost recording device, and the progress of project cost in both aspects can be recorded.
[0037] S3: Through real-time monitoring of the engineering cost recording device, the specific category of engineering cost is determined, and then selectively recorded. After recording, the device erases the recorded content and makes the recording area of the engineering cost recording method in a brand new state for the next recording.
[0038] The engineering cost recording method in S1 includes a base 1, with support brackets 2 fixedly installed at both ends of the bottom of the base 1. An adjustment mechanism is installed on the base 1. It also includes a carrier plate 3, with two symmetrically distributed panels 4 on one side of the carrier plate 3. The panels 4 are made of blackboard material. A connecting seat 5 is fixedly installed at the bottom of the carrier plate 3, and the connecting seat 5 is connected to the adjustment mechanism. A cleaning mechanism is installed on the panels 4. Anti-slip pads are provided on the bottom of each support bracket 2. The cleaning mechanism includes a drive shaft 6. The carrier plate 3 is a circular plate. The drive shaft 6 is rotatably installed at the center of the carrier plate 3. A radial plate 7 is fixedly installed at the end of the drive shaft 6, distributed along the diameter of the carrier plate 3. Two symmetrically distributed mounting plates 8 are fixedly installed on the side of the radial plate 7 facing the carrier plate 3. Cotton blocks 9 are fixedly installed on the side of each mounting plate 8 facing the carrier plate 3, and the cotton blocks 9 can contact the panels 4.
[0039] The cleaning mechanism also includes a drive assembly, which includes a connecting shaft 10. The connecting shaft 10 is rotatably mounted on the back side of the panel 4 and passes through the panel 4. The connecting shaft 10 is fixedly connected to the drive shaft 6. A gear 11 is fixedly mounted at the end of the connecting shaft 10. A motor 12 is fixedly mounted on the panel 4. An incomplete gear 13 is fixedly mounted at the output shaft end of the motor 12. The incomplete gear 13 can mesh with the gear 11. A dust cover is mounted on the motor 12.
[0040] The device features a cleaning mechanism. It records different types of project cost progress information on panel 4. After recording, the cotton block 9 on the radial plate 7 cleans the ink marks on the surface of panel 4. The motor 12 drives the incomplete gear 13 to rotate, which in turn drives the gear 11 to rotate, thereby causing the connecting shaft 10 and the radial plate 7 to rotate synchronously. The cotton block 9 comes into contact with the ink marks on the surface of panel 4, thus achieving automated cleaning of the ink marks. As a result, the ink marks on the recording board do not need to be manually cleaned by the operator. During the cleaning process, the operator no longer comes into direct contact with chalk dust, thereby avoiding harm to the operator's health.
[0041] The panel 4 has two symmetrically distributed through slots 14 that penetrate the panel 4. The two through slots 14 are symmetrically distributed and each slot 14 has a slot 15 on both sides. It also includes two movable seats 16, which are respectively set in the through slots 14. Side blocks 17 are fixedly installed on both sides of the movable seats 16 and are slidably set in the slots 15. Multiple atomizing nozzles 18 are fixedly installed on the upper movable seat 16 and are equidistantly distributed. The atomizing nozzles 18 are set towards the cotton block 9. A pipe 19 is fixedly installed on the upper movable seat 16 and passes through the movable seat 16 and is connected to the multiple atomizing nozzles 18. A pump body 20 is fixedly installed on the upper movable seat 16. The drain pipe of the pump body 20 is connected to the pipe 19 and the inlet pipe of the pump body 20 is connected to an external water source. During the cleaning process, water is drawn in by the pump body 20 and atomized and discharged by multiple atomizing nozzles 18, thereby humidifying the surface of the cotton block 9 and preventing a large amount of dust from being generated near the cotton block 9.
[0042] Working principle: The device is equipped with a cleaning mechanism. It records the progress information of different types of engineering cost projects on the panel 4. After the recording is completed, the cotton block 9 on the radial plate 7 cleans the pen marks on the surface of the panel 4. The motor 12 drives the incomplete gear 13 to rotate, and the incomplete gear 13 drives the gear 11 to rotate, thereby driving the connecting shaft 10 and the radial plate 7 to rotate synchronously. The cotton block 9 comes into contact with the pen marks on the surface of the panel 4, thereby realizing the automatic cleaning of the pen marks. Thus, the pen marks on the recording board do not need to be manually cleaned by the operator. During the cleaning process, the operator no longer comes into direct contact with chalk dust, thereby avoiding harm to the operator's health.

[0045] During the cleaning process, water is drawn in by the pump body 20 and atomized and discharged by multiple atomizing nozzles 18, thereby humidifying the surface of the cotton block 9 and preventing a large amount of dust from being generated near the cotton block 9. A negative pressure gas is generated at the guide channel 31 by the air pump 29, causing a small amount of dust to be drawn into the air pump 29. The air pump 29 then discharges the dust to a unified location for cleaning. The motor 27 drives the drive wheel 28 to rotate, which in turn drives the transmission wheel 26. Combined with the transmission of multiple gears 24 and 25, multiple cam columns 23 rotate synchronously. The cleaning brushes on the cam columns 23 remove dust from the surface of the cotton block 9, further improving the cleaning effect and preventing a large amount of dust from accumulating on the cotton block 9.

[0049] Working principle: During the cleaning process, water is drawn in by the pump body 20 and atomized and discharged by multiple atomizing nozzles 18, thereby humidifying the surface of the cotton block 9 and preventing a large amount of dust from accumulating near the cotton block 9. A negative pressure gas is generated at the guide channel 31 by the air pump 29, causing a small amount of dust to be drawn into the air pump 29. The air pump 29 then discharges the dust to a unified location for cleaning. The motor 27 drives the drive wheel 28 to rotate, which in turn drives the transmission wheel 26. Combined with the transmission of multiple gears 24 and 25, multiple cam columns 23 rotate synchronously. The cleaning brushes on the cam columns 23 remove dust from the surface of the cotton block 9, further improving the cleaning effect and preventing the accumulation of large amounts of dust on the cotton block 9. The servo motor 40 drives the gear 41 to rotate, and the hydraulic cylinder 38 drives the movable frame 39 to move up and down. This allows the gear 41 to rotate sequentially with the driven wheel 34 and the driven wheel 37, thereby driving the reciprocating screw 32 and the reciprocating screw 35 to rotate sequentially. This allows the two movable seats 16 to move up and down sequentially, enabling the atomizing nozzle 18 to humidify all areas of the cotton block 9 surface.
