Description

Technical Field

[0001] The invention relates to the technical field of concrete pumping monitoring, and in particular to a remote monitoring device for concrete status. Background Art

[0002] With the development of society, the scale of urban construction continues to expand, and the continuous progress of transportation technology has brought great convenience to the construction of various infrastructures. Therefore, concrete pumping technology has been widely used in modern construction. The application of concrete pumping technology not only improves construction efficiency and reduces the burden of manpower, but also makes the construction of complex structures such as high-rise buildings, bridges and tunnels possible. However, the concrete pumping process will be affected by many unfavorable factors, such as improper operation, material quality problems, changes in environmental conditions, etc., which may lead to a decline in concrete quality, thereby affecting the quality and safety of the entire project.

[0003] Therefore, in actual construction, it is particularly important to monitor the quality of concrete pumping. Real-time monitoring of the concrete pumping process can effectively avoid human operational errors and prevent the reduction of concrete strength or other physical properties due to malicious addition of water or mixing of non-compliant materials. In addition, with the improvement of construction quality supervision requirements, the tracking and tracing mechanism of concrete quality has gradually become one of the key links in construction. Through monitoring technology, the construction party can provide a reliable basis for the concrete pumping process. Once a quality problem occurs, the source of the problem can be quickly located and remedial measures can be taken in time to ensure that the overall quality of the project meets the standards.

[0004] However, in actual operation, since the camera equipment of a concrete pump truck is usually installed at the hopper at the rear of the truck, when concrete is poured into the hopper, it often splashes due to gravity acceleration. These splashing concrete particles may block the camera lens, affecting the clarity and accuracy of video monitoring, or even causing the camera to temporarily fail to work properly. This phenomenon not only affects the monitoring effect, but also increases the risk of uncontrollable factors during the construction process.

[0005] Chinese patent CN116511120B discloses a fixed-point video monitoring device for concrete pumping, comprising a concrete pumping bucket, and a monitoring mechanism arranged on the surface of the concrete pumping bucket, wherein the monitoring mechanism comprises a monitoring component, a rotating component, a lifting component and a circulation component, wherein the monitoring component is installed on the surface of the concrete pumping bucket, the rotating component is arranged on the surface of the monitoring component and connected to the monitoring component, the lifting component is arranged inside the rotating component, and the circulation component is arranged on the surface of the monitoring component;

[0006] The monitoring device drives the lifting sleeve to drive the spiral scraper to rotate upward and then descend vertically, so as to achieve the effect of cleaning foreign objects adhering to the surface of the transparent protective cover. However, when the device is scraping foreign objects such as splashed concrete on the outer surface of the transparent protective cover, the scraped concrete particles will accumulate at the bottom of the scraper due to the adhesion of concrete particles. When the scraper rises, the concrete particles may adhere to the scraper and re-adhere to the outer surface of the transparent protective cover, thereby failing to effectively clean the outer surface of the transparent protective cover, thereby affecting the monitoring effect.

[0007] Therefore, how to design a monitoring device that can effectively prevent residual concrete from secondary contamination of the outer surface of the transparent cover to ensure the continuous and stable operation of the equipment is an urgent problem to be solved by technical personnel in this field.

The two ends of the connecting plate are respectively fixedly connected to the top of the lifting cylinder and the output shaft of the electric push rod.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The remote monitoring device for concrete status designed in the present application can not only thoroughly clean the splashed concrete and other foreign objects attached to the outer surface of the transparent cylinder through the lifting cylinder and the end face cleaning mechanism, but also can thoroughly clean the concrete accumulated at the bottom of the lifting cylinder due to scraping and pushing. While effectively avoiding the accumulated concrete from attaching to the surface of the transparent cylinder for the second time as the lifting cylinder is reset to form a new obstacle, it can effectively prevent the long-term accumulation of concrete from causing corrosion and wear to the equipment parts, thereby improving the overall operation reliability and sustainability of the equipment, extending the service life of the equipment parts, and reducing the equipment maintenance cost and replacement frequency.

[0021] 2. The end face cleaning mechanism designed in this application can not only effectively scrape off stains such as concrete at the bottom of the lifting tube through the mutual cooperation of internal components, but also effectively realize the self-cleaning function, further improving the cleaning efficiency.

[0022] Specifically, when the bottom of the lifting cylinder contacts the top of the end face cleaning mechanism and descends, the internal components of the end face cleaning mechanism cooperate with each other, and while the scraper ring rotates downward to clean the dirt accumulated at the bottom of the lifting cylinder, it can also generate vibration to help loosen and separate dirt attached to the scraper ring, ensuring that its surface always remains clean; when the lifting cylinder resets and rises, the elastic reset element assists the scraper ring to return to its position, which can not only achieve secondary cleaning of the bottom of the lifting cylinder, but also achieve secondary self-cleaning of the scraper ring.

[0023] 3. The lifting cylinder designed in the present application, through the precise coordination of rubber, stepped ring groove, positioning cylinder and limit ring, can ensure that the rubber ring will not be excessively worn or fall off while ensuring that the rubber ring continuously and effectively cleans the outer surface of the transparent cylinder, thereby ensuring the long-term and stable operation of the equipment.

DETAILED DESCRIPTION

[0035] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0036] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this application provides:

[0037] A remote monitoring device for concrete state comprises a bracket 1, a transparent cylinder 2, a monitoring camera 3, a lifting cylinder 4, a lifting drive mechanism 5, an end face cleaning mechanism 6 and a controller 7. The bracket 1 is arranged at a concrete pump feed hopper, the bracket 1 has a mounting platform extending in a horizontal direction, the transparent cylinder 2 is arranged at the top of the mounting platform in a longitudinal direction, the monitoring camera 3 is installed in the transparent cylinder 2, the lifting cylinder 4 is coaxially slidably arranged on the outer circumferential surface of the transparent cylinder 2, the top of the lifting cylinder 4 is closed, and the lifting cylinder 4 and the transparent cylinder 2 are gap-matched. When the lifting cylinder 4 slides downward relative to the transparent cylinder 2, the bottom end of the lifting cylinder 4 pushes the stains on the outer circumferential surface of the transparent cylinder 2 downward, the lifting drive mechanism 5 is arranged on the bracket 1, and the working end of the lifting drive mechanism 5 is connected to the lifting cylinder 4. The end face cleaning mechanism 6 is arranged at the bottom end of the transparent cylinder 2. When the bottom end of the transparent cylinder 2 abuts against the end face cleaning mechanism 6, the end face cleaning mechanism 6 cleans the bottom end of the lifting cylinder 4. The controller 7 is installed on the bracket 1, and the controller 7 is electrically connected to the monitoring camera 3 and the lifting drive mechanism 5.

[0038] A remote monitoring device for concrete status includes a bracket 1, a transparent cylinder 2, a monitoring camera 3, a lifting cylinder 4, a lifting drive mechanism 5, an end surface cleaning mechanism 6 and a controller 7. The bracket 1 is installed at the feed hopper of the concrete pump and has a mounting platform extending in the horizontal direction. The transparent cylinder 2 is arranged at the top of the mounting platform in the longitudinal direction. The monitoring camera 3 is installed inside the transparent cylinder 2 to monitor the status of the concrete. The lifting cylinder 4 is coaxially slidably arranged on the outer circumference of the transparent cylinder 2. The top of the lifting cylinder 4 is closed and there is a gap fit between the lifting cylinder 4 and the transparent cylinder 2. When the lifting cylinder 4 slides downward relative to the transparent cylinder 2, the bottom end of the lifting cylinder 4 will push the stains or concrete residues on the outer circumference of the transparent cylinder 2 downward, thereby cleaning the outer surface of the transparent cylinder 2. The lifting drive mechanism 5 is installed on the bracket 1, and its working end is connected to the lifting cylinder 4 to drive the lifting cylinder 4 to slide in the vertical direction. The end surface cleaning mechanism 6 is installed at the bottom end of the transparent cylinder 2. When the lifting cylinder 4 slides downward and the bottom end of the transparent cylinder 2 contacts the end surface cleaning mechanism 6, the end surface cleaning mechanism 6 can effectively clean the bottom end of the lifting cylinder 4 to prevent the concrete from re-adhering to the outer surface of the transparent cylinder 2 as the lifting cylinder 4 is reset. The controller 7 of the entire device is installed on the bracket 1 and is electrically connected to the monitoring camera 3 and the lifting drive mechanism 5. Through the coordinated control of the controller 7, the precise movement of the lifting cylinder 4 and the remote monitoring operation of the monitoring camera 3 are realized, ensuring that the device can operate efficiently for a long time.

[0039] The device is designed such that the lifting cylinder 4 is coaxially slidably arranged on the outer circumference of the transparent cylinder 2 and is in clearance with the transparent cylinder 2, so that when the lifting cylinder 4 moves downward, it can effectively scrape off foreign objects such as splashed concrete attached to the surface of the transparent cylinder 2. Specifically, during operation, the lifting cylinder 4 cleans the concrete dirt on the surface of the transparent cylinder 2 through a scraping and pushing action, preventing it from interfering with the line of sight of the monitoring camera 3, thereby affecting the monitoring effect.

[0040] At the same time, the design of the end face cleaning mechanism 6 in the device can thoroughly clean the concrete residue produced by scraping and pushing at the bottom of the lifting cylinder 4, effectively avoiding the accumulated concrete from attaching to the surface of the transparent cylinder 2 again as the lifting cylinder 4 is reset to form a new obstacle, and effectively improving the working efficiency of the monitoring camera 3.

[0041] Therefore, the device can not only keep the surface of the transparent cylinder 2 clean and ensure the continuous monitoring function of the monitoring camera 3, but also improve the overall operation reliability of the equipment by preventing secondary adhesion of concrete.

[0042] like Figure 4 and Figure 5 As shown, a rubber ring 41 is provided at the bottom end of the lifting cylinder 4. The rubber ring 41 is sleeved on the outer circumference of the transparent cylinder 2. The rubber ring 41 and the transparent cylinder 2 are interference fit. When the lifting cylinder 4 is lifted or lowered relative to the transparent cylinder 2, the lifting cylinder 4 drives the rubber ring 41 to lift or lower on the outer circumference of the transparent cylinder 2.

[0043] A rubber ring 41 is designed at the bottom end of the lifting cylinder 4. The rubber ring 41 is sleeved on the outer circumference of the transparent cylinder 2. The rubber ring 41 and the transparent cylinder 2 are in an interference fit so that they can closely contact the surface of the transparent cylinder 2. When the lifting cylinder 4 is lifted relative to the transparent cylinder 2, the lifting cylinder 4 drives the rubber ring 41 to slide up and down along the outer circumference of the transparent cylinder 2. Due to the close fit between the rubber ring 41 and the transparent cylinder 2, during the lifting process, the rubber ring 41 can generate sufficient friction on the surface of the transparent cylinder 2, effectively cleaning the concrete residues or other impurities attached to the outer surface of the transparent cylinder 2.

[0044] This design ensures that the rubber ring 41 will not lose its cleaning effect due to looseness when the equipment is in operation, and also avoids the situation of incomplete cleaning. At the same time, the rubber material has a certain elasticity and wear resistance, which can meet the wear requirements of long-term use and will not cause damage to the surface of the transparent tube 2. The up and down sliding action of the rubber ring 41 can continuously and effectively push the concrete residue downward, thoroughly clean the outer surface of the transparent tube 2, maintain a clear field of view for the monitoring camera 3, and avoid obstruction of vision.

[0045] like Figure 5 and Fig. 9As shown, the rubber ring 41 is coaxially abutted against the bottom end of the transparent tube 2, the bottom end of the outer circumferential surface of the rubber ring 41 is provided with a coaxial stepped ring groove, the bottom end of the outer circumferential surface of the lifting tube 4 is provided with a positioning tube 42 threadedly connected thereto, the bottom end of the inner circumferential surface of the positioning tube 42 is provided with a limiting ring 421, and the limiting ring 421 is embedded in the stepped ring groove.

[0046] The rubber ring 41 is coaxially abutted against the bottom end of the transparent tube 2 to ensure that it is closely matched with the transparent tube 2 to achieve a good sealing and cleaning effect. The bottom end of the outer circumferential surface of the rubber ring 41 is designed with a coaxial stepped annular groove, which not only helps to enhance the structural stability of the rubber ring 41, but also provides additional support and limit functions to ensure that the rubber ring 41 does not deviate from its set track during movement.

[0047] At the bottom end of the outer circumference of the lifting cylinder 4, a positioning cylinder 42 connected by a thread is provided. This threaded connection design provides an adjustable fixing method for the cooperation between the rubber ring 41 and the lifting cylinder 4. The positioning cylinder 42 can ensure that the rubber ring 41 maintains accurate coaxial movement during the sliding process to prevent any possible deviation. The advantage of the threaded connection is that it can adjust the contact pressure between the rubber ring 41 and the transparent cylinder 2 according to actual needs, thereby improving the cleaning efficiency.

[0048] A stop ring 421 is provided at the bottom of the inner circumference of the positioning cylinder 42. The function of the stop ring 421 is to provide a stable fit for the stepped ring groove. The stepped ring groove of the rubber ring 41 is precisely fitted with the stop ring 421 to form a stable limit structure, which effectively limits the up and down sliding range of the rubber ring 41 during the lifting movement, and prevents displacement and wear caused by excessive movement or vibration. This fitting design not only improves the durability of the device, but also enhances the overall stability and working efficiency of the lifting cylinder 4.

[0049] Through the precise coordination of the rubber ring 41, the stepped ring groove, the positioning tube 42 and the limiting ring 421, the entire system can keep the rubber ring 41 cleaning the outer surface of the transparent tube 2 while ensuring that the rubber ring 41 will not be excessively worn or fall off during long-term use, thereby ensuring the long-term and stable operation of the equipment.

[0050] like Fig. 9 and Fig.10 As shown, the monitoring device also includes a base 8, which is arranged at the top of the bracket 1. The top of the base 8 is provided with an engaging seat in which the transparent tube 2 is engaged. The lifting drive mechanism 5 has a scraper ring 61 located at the top of the outer circumferential surface of the base 8. The top of the scraper ring 61 is provided with scraper pieces 611 distributed along its circumference. When the rubber ring 41 abuts against the top of the scraper ring 61 and drives it to move downward, the scraper piece 611 moves along the circumference of the scraper ring 61 and scrapes off the stains at the bottom of the rubber ring 41.

[0051] The monitoring device also includes a base 8, which is firmly mounted on the top of the bracket 1 to support the weight of the entire device and provide a stable operating platform. At the top of the base 8, a fitting seat for fitting the transparent tube 2 is provided. This fitting connection design not only ensures the stability of the transparent tube 2, but also facilitates the installation and removal of the transparent tube 2, and is convenient for later maintenance and replacement.

[0052] There is interaction between the scraper ring 61 and the rubber ring 41. When the rubber ring 41 abuts against the top of the scraper ring 61, it will maintain stable contact with the scraper ring 61 and drive the scraper ring 61 to move downward during the lifting movement. The top of the scraper ring 61 is provided with a plurality of scraper blades 611 distributed along the circumference. The function of these scraper blades 611 is to scrape off the stains and impurities at the bottom of the rubber ring 41, prevent dirt from accumulating at the bottom of the rubber ring 41, and ensure that it always keeps a clean state when in contact with the surface of the transparent tube 2.

[0053] When the rubber ring 41 slides downward driven by the lifting cylinder 4, the scraper blade 611 moves synchronously along the circumference of the scraper ring 61, and through its scraping function, it can effectively clean the attachments at the bottom of the rubber ring 41, such as concrete residues, soil or other impurities. This design cleverly combines the cleaning function and the movement function, ensuring that the rubber ring 41 is always in good working condition during the operation of the equipment, avoiding the decrease in cleaning effect caused by the accumulation of stains.

[0054] like Figure 6 As shown, the lifting drive mechanism 5 also includes an elastic reset element 62 arranged between the scraper ring 61 and the bracket 1. When the scraper ring 61 moves downward relative to the base 8, the scraper ring 61 needs to overcome the elastic force of the elastic reset element 62. The inner circumferential surface of the scraper ring 61 is provided with guide columns 612 distributed along its circumference. The guide columns 612 extend along the radial direction of the scraper ring 61. The circumferential surface of the base 8 is provided with arc grooves 81 distributed along its circumference. The guide columns 612 extend into the arc grooves 81 and slide with them.

[0055] In the lifting drive mechanism 5, in addition to the cleaning design of the rubber ring 41 and the scraper ring 61, an elastic reset element 62 is also provided between the scraper ring 61 and the bracket 1. The function of the elastic reset element 62 is to provide a certain resistance when the scraper ring 61 moves downward relative to the base 8. During the movement, the scraper ring 61 needs to overcome the elastic force of the elastic reset element 62 to complete its downward movement. This design ensures that the scraper ring 61 can automatically return to its original position through the force of the elastic reset element 62 after completing the cleaning work, so that the system always remains in an initial working state, which is convenient for the next operation.

[0056] The inner circumferential surface of the scraper ring 61 is also specially provided with guide posts 612 distributed along the circumference thereof. These guide posts 612 extend along the radial direction of the scraper ring 61 and are used to control the movement trajectory of the scraper ring 61 to ensure that it does not deviate during movement. The circumferential surface of the base 8 is designed with arc grooves 81 distributed along the circumference. The other end of the guide post 612 extends into the arc groove 81 and forms a sliding fit with the groove. The purpose of this matching design is to ensure that the scraper ring 61 can maintain a stable running trajectory during the up and down movement, and the scraper ring 61 will not be stuck or deviate from the predetermined path due to external force or eccentricity.

[0057] The cooperation between the guide column 612 and the arc groove 81 ensures that the scraper ring 61 moves downward in a rotating state, so that after the rubber ring 41 descends to scrape the concrete, the attached concrete can be scraped off by the rotating scraper blade 611. The design of the arc groove 81 allows the guide column 612 to slide freely inside it, thereby allowing the scraper ring 61 to maintain an accurate posture during the lifting process. At the same time, the design of the elastic reset element 62 can quickly reset the scraper ring 61 through its own elastic force after the scraper ring 61 completes cleaning. This structure not only ensures the accurate positioning of the scraper ring 61, but also provides a guarantee for the automatic cleaning function of the system.

[0058] like Figure 6 As shown, the arc groove 81 is provided with inner grooves 811 arranged at equal intervals along its extension direction, and the inner side extends radially along the base 8. A mounting groove coaxial with the guide column 612 is provided in the guide column 612, and a limiting table is provided in the mounting groove. A knocking pin 63 is provided in the mounting groove, and a round head capable of entering the inner groove 811 is provided at one end of the knocking pin 63 facing the base 8, and a knocking seat 631 is provided at the other end of the knocking pin 63. An elastic abutment element 64 is provided at the end of the knocking seat 631 and the mounting groove deviating from the base 8. When the guide column 612 slides in the arc groove 81, the knocking pin 63 reciprocates radially along the base 8, and the knocking seat 631 reciprocates radially along the base 8 to knock the limiting table.

[0059] The knock pin 63 is provided with a round head that can enter the inner groove 811 at one end facing the base 8. When the guide post 612 slides along the arc groove 81, the round head will enter or exit the inner groove 811 along with the movement of the guide post 612. In this way, the knock pin 63 reciprocates along the radial direction of the base 8 driven by the guide post 612. This reciprocating motion is supported by the elastic abutment element 64 in the mounting groove, which ensures that the knock pin 63 can be quickly reset when exiting and entering the inner groove 811, so as to maintain the continuous action of the system.

[0060] The other end of the knocking pin 63 is connected to a knocking seat 631. The knocking seat 631 is located on the side of the mounting groove that deviates from the base 8, and maintains dynamic contact with the mounting groove through the elastic abutment element 64. When the guide column 612 slides in the arc groove 81, the knocking pin 63 drives the knocking seat 631 to knock the limit table back and forth along the radial direction of the base 8. This process generates vibrations of the scraper ring 61 and the scraper sheet 611 through repeated knocking of the knocking seat 631.

[0061] The design intention of this knocking and vibration is to accelerate the cleaning process through vibration. When the scraper ring 61 descends, the knocking pin 63, under the action of the elastic abutment element 64, quickly withdraws and enters the inner groove 811, causing the knocking seat 631 to frequently knock the limit table. This rapid knocking action will be transmitted to the scraper ring 61 and the scraper sheet 611, causing them to produce a significant vibration effect. These vibrations can effectively help loosen and separate concrete or other dirt attached to the scraper ring 61, thereby accelerating the cleaning process and ensuring that the surface of the scraper ring 61 is always kept clean.

[0062] like Fig. 9 As shown, the top of the scraper ring 61 is provided with an annular cone surface, and the diameter of the annular cone surface gradually decreases from bottom to top.

[0063] The top of the scraper ring 61 is designed with an annular cone surface, and the cone structure can guide concrete or other dirt to slide naturally along the surface of the scraper ring 61, which helps prevent dirt from accumulating on the top of the scraper ring 61. Through such a geometric design, the device can achieve a self-cleaning function while scraping stains, further improving the cleaning efficiency.

[0064] like Figure 6 As shown, a bellows 9 is also provided between the scraper ring 61 and the bracket 1, the top end of the bellows 9 is fixedly connected to the bottom end of the scraper ring 61, the bottom end of the bellows is fixedly connected to the mounting platform, and the elastic reset element 62 is located between the inner circumferential surface of the bellows and the outer circumferential surface of the base 8.

[0065] The top of the bellows 9 is fixedly connected to the bottom of the scraper ring 61, ensuring that the bellows 9 can work in coordination with the movement of the scraper ring 61. The advantage of this connection method is that when the scraper ring 61 moves up and down during cleaning or operation, the bellows 9 can expand and contract accordingly, which can effectively prevent concrete from sticking to the elastic reset element 62 and affecting its elastic effect.

[0066] like Figure 7As shown, the bracket 1 includes a bottom plate 11, a top plate 12, a connecting column 13, a limiting nut 14 and an elastic shock-absorbing element 15. The bottom plate 11 and the top plate 12 are horizontally arranged at the concrete pump feed hopper, the connecting column 13 is arranged between the bottom plate 11 and the top plate 12, the bottom end of the connecting column 13 is fixedly connected to the bottom plate 11, the top end of the connecting column 13 slides longitudinally through the top plate 12, the limiting nut 14 is coaxially arranged at the top end of the connecting column 13 and is located at the top end of the top plate 12, the elastic shock-absorbing element 15 is arranged on the connecting column 13, the elastic shock-absorbing element 15 is located between the bottom plate 11 and the top plate 12, and the bottom surface of the top plate 12 forms a mounting platform.

[0067] The bracket 1 is composed of a bottom plate 11, a top plate 12, a connecting column 13, a limit nut 14 and an elastic shock-absorbing element 15. The bottom plate 11 and the top plate 12 are horizontally arranged at the concrete pump feed hopper to form a stable support. The bottom end of the connecting column 13 is fixed on the bottom plate 11, and the top end slides longitudinally through the top plate 12. The limit nut 14 is installed on the top of the connecting column 13 to control its sliding range and prevent excessive displacement. The elastic shock-absorbing element 15 is located on the connecting column 13, between the bottom plate 11 and the top plate 12, and can absorb vibrations during equipment operation and reduce impact on the equipment. The overall design ensures that the bracket 1 has good support, adjustability and shock absorption effects, thereby improving the stability and durability of the equipment.

[0068] like Figure 2 As shown, the lifting drive mechanism 5 includes an electric push rod 51 and a connecting plate 52. The electric push rod 51 is longitudinally arranged at the top of the mounting platform. The output shaft of the electric push rod 51 extends longitudinally. The two ends of the connecting plate 52 are fixedly connected to the top of the lifting cylinder 4 and the output shaft of the electric push rod 51 respectively.

[0069] The lifting drive mechanism 5 is composed of an electric push rod 51 and a connecting plate 52. The electric push rod 51 is installed on the top of the mounting platform in the longitudinal direction, and its output shaft also extends longitudinally. The connecting plate 52 is located at the top of the lifting cylinder 4, and its two ends are fixedly connected to the top of the lifting cylinder 4 and the output shaft of the electric push rod 51 respectively. Driven by the electric push rod 51, the lifting cylinder 4 can move up and down to achieve lifting adjustment. This design ensures precise lifting control of the equipment and improves the operating efficiency and stability of the system.

[0070] When it is necessary to clean the concrete on the outer surface of the transparent cylinder 2, the electric push rod 51 is started, and its output shaft drives the lifting cylinder 4 to move downward, so that the rubber ring 41 installed at the bottom end of the lifting cylinder 4 can push the concrete on the surface of the transparent cylinder 2 downward until the rubber ring abuts against the top of the scraper ring 61, and the lifting cylinder 4 continues to move downward, so that the scraper ring 61 overcomes the elastic force of the elastic reset element 62 and moves downward. At the same time, under the guidance of the guide column and the arc groove 81 on the base 8, the scraper ring 61 will rotate automatically during the descent process, so that the scraper sheet 611 on the scraper ring 61 scrapes off the concrete remaining at the bottom end of the rubber ring 41, avoiding When the lifting cylinder 4 rises, the concrete at the bottom of the rubber ring 41 re-contaminates the outer wall of the transparent cylinder 2. During the rotation and descent of the scraper ring 61, the knocking pin 63 continues to overcome the elastic force of the elastic abutment element 64 and cooperates with the inner groove 811 in the arc groove 81, so that the knocking pin 63 can vibrate the scraper ring 61 to help loosen and separate the dirt attached to the scraper ring 61, ensuring that its surface always remains clean; when the lifting cylinder 4 resets and rises under the action of the electric push rod 51, the elastic reset element 62 assists the scraper ring 61 to return to its position, which can not only achieve secondary cleaning of the bottom of the lifting cylinder, but also achieve secondary self-cleaning of the scraper ring.

It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
