Description

Technical Field

[0001] This utility model relates to the field of sludge scraper technology, specifically a sludge scraper with a reliable self-protection alarm function. Background Technology

[0002] As is well known, sedimentation tanks are often used in urban sewage treatment plants, waterworks, and industrial wastewater treatment to perform preliminary sedimentation and purification of sewage. The relatively clear water is discharged from the upper part of the sedimentation tank, while a large amount of sludge settles at the bottom of the tank. Sludge scrapers, as key equipment, are widely used in treatment facilities such as sedimentation tanks to regularly remove the sludge accumulated at the bottom of the tank in order to maintain the normal operation of the treatment facilities and the quality of the effluent.

[0003] During operation, traditional sludge scrapers are prone to abnormal situations such as abnormal speed and equipment overload due to changes in sludge volume, fluctuations in equipment load, and the influence of external environmental factors. Due to the lack of effective monitoring and alarm mechanisms, these abnormal situations are often difficult to detect and handle in a timely manner, leading to equipment damage, downtime for maintenance, or even safety accidents. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a sludge scraper with a reliable self-protection alarm function.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a sludge scraper with reliable self-protection alarm function, comprising a sedimentation tank, a cylinder, a first motor, a control box, a lifting assembly, and an alarm. The sedimentation tank has a sludge collection trough, a sludge discharge pipe is installed at the bottom of the sludge collection trough, and a pump body is installed on the sludge discharge pipe. A fixed pile is installed in the middle of the sedimentation tank, and the cylinder is installed inside the fixed pile. The first motor is installed at the output end of the cylinder, and a turntable is installed at the output end of the first motor. The control box is installed at the top of the turntable and is electrically connected to the first motor. Horizontal bars are installed on both the left and right sidewalls of the turntable, and several vertical bars are installed at the bottom of the horizontal bars. A bottom scraper is installed at an angle on the bottom wall of each group of vertical bars. A sensor is installed at the top of the vertical bars and is electrically connected to the control box. The lifting assembly is installed at the top of the control box, and the alarm is fixedly installed at the top of the lifting assembly.

[0008] To facilitate the lifting of the alarm, this utility model is improved by including a fixed frame, a bidirectional screw, a second motor, a slider, a scissor-type connecting rod, and a lifting frame. The fixed frame is fixedly installed on the top wall of the control box. The bidirectional screw is rotatably installed inside the fixed frame. One end of the bidirectional screw passes through the side wall of the fixed frame and is fitted with the second motor. The sliders are threaded onto both the left and right ends of the bidirectional screw. The top walls of the two sets of sliders are fixedly connected to the bottom ends of the scissor-type connecting rod. The lifting frame is slidably installed on the top of the scissor-type connecting rod, and the alarm is installed on the top of the lifting frame.

[0009] To ensure the stable lifting of the lifting frame, the present invention is improved by fixing a guide rod inside the lifting frame, and sliding guide blocks are installed at the left and right ends of the guide rod. The bottom walls of the two sets of guide blocks are respectively fixedly connected to the top ends of the scissor-type connecting rod.

[0010] Preferably, in this invention, a connecting rod is horizontally welded to the lower part of several of the vertical rods, and a side scraper is installed at the end of the connecting rod away from the fixed pile.

[0011] To ensure the stability and accuracy of the operation of the first and second motors, this utility model is improved by making the first and second motors servo motors.

[0012] Preferably, in this invention, both the bottom scraper and the side scraper are made of carbon steel.

[0013] To enhance the connection strength between each group of vertical plates, this utility model is improved by installing a reinforcing rod between each group of adjacent vertical bars.

[0014] Preferably, in this invention, the alarm consists of a buzzer and an alarm light.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a sludge scraper with a reliable self-protection alarm function, which has the following beneficial effects:

[0017] This sludge scraper, equipped with a reliable self-protection alarm function, monitors the working status of the scraper in real time through sensors and a control box. Once an abnormality is detected, such as an abnormal crossbar speed, the sensor immediately sends a signal to the control box, cutting off the power to the first motor. The control box then activates the self-protection alarm function. This intelligent monitoring and self-protection alarm mechanism can promptly detect and address potential problems, prevent further damage to the equipment, and ensure the safe operation of the sludge scraper.

[0018] This sludge scraper, equipped with a reliable self-protection alarm function, can raise the turntable by controlling the output end of the cylinder when the amount of sludge is large or the sludge layer is thick, causing the equipment to overload. This allows the bottom scraper to rise a certain distance, thus cleaning the deposited sludge layer by layer from top to bottom, effectively reducing the load of a single sludge scraping and improving the adaptability and flexibility of the equipment.

[0019] This sludge scraper with reliable self-protection alarm function uses a lifting assembly to control a second motor that drives a bidirectional screw to rotate. The sliders at the left and right ends move relative to each other along the thread direction of the bidirectional screw, allowing the scissor linkage to unfold smoothly. This, in turn, raises the lifting frame and the alarm to a conspicuous position, whereby the alarm emits an alarm signal to alert the operator and prompt them to take appropriate action.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-4A sludge scraper with reliable self-protection alarm function includes a sedimentation tank 1, a cylinder 2, a first motor 3, a control box 4, a lifting assembly, and an alarm 5. The sedimentation tank 1 has a sludge collection trough 6, and a sludge discharge pipe 7 is installed at the bottom of the sludge collection trough 6. A pump body 8 is installed on the sludge discharge pipe 7. A fixed pile 9 is installed in the middle of the sedimentation tank 1, and the cylinder 2 is installed inside the fixed pile 9. The first motor 3 is installed at the output end of the cylinder 2, and a turntable 10 is installed at the output end of the first motor 3. The control box 4 is installed at the top of the turntable 10 and is electrically connected to the first motor 3. Horizontal bars 11 are installed on both the left and right side walls of the turntable 10. Several vertical rods 12 are installed at the bottom. A bottom scraper 13 is installed at an angle on the bottom wall of each set of vertical rods 12. A sensor 14 is installed at the top of each vertical rod 12. The sensor 14 is electrically connected to the control box 4. The lifting assembly is installed at the top of the control box 4, and the alarm 5 is fixedly installed at the top of the lifting assembly. In this embodiment, during use, the control box 4 is started. The control box 4 is electrically connected to the first motor 3, thereby controlling the start of the first motor 3. After the first motor 3 starts, it drives the turntable 10 to rotate. The control box 4 and the horizontal rod 11 on the turntable 10 rotate accordingly. As the turntable 10 rotates, the several vertical rods 12 and the bottom scraper 13 at the bottom of the horizontal rod 11 begin to move around the center of the sedimentation tank 1. The scraper blade 13 is installed at an angle to more effectively remove sludge from the bottom of the pool. A sensor 14 at the top of the vertical rod 12 monitors the scraper's operating status in real time. If an abnormality is detected (such as excessive sludge causing equipment overload), the sensor 14 sends a signal to the control box 4. The control box 4 determines whether to activate the self-protection alarm function based on the signal from the sensor 14. If an abnormality is detected (such as the horizontal rod 11 not rotating at the normal speed), the control box 4 will automatically cut off the power to the first motor 3, stopping the scraping operation to prevent further damage to the equipment. Simultaneously, the control box 4 activates the lifting assembly, raising the alarm 5 to a conspicuous position, and the alarm 5 emits an alarm signal to remind the operator. If the sludge volume is large or the sludge layer is thick, causing the equipment to overload, the operator can control the output end of cylinder 2 to drive the turntable 10 to rise, so that the bottom scraper 13 rises a certain distance. Then, the first motor 3 is restarted to perform the sludge scraping operation, so that the bottom scraper 13 cleans the deposited sludge layer by layer from top to bottom. During the sludge scraping process, the scraped sludge is pushed into the sludge collection trough 6 in the sedimentation tank 1 (the inclined design of the bottom scraper 13 makes it easy to push the sludge towards the middle). The sludge discharge pipe 7 at the bottom of the sludge collection trough 6 is equipped with a pump body 8. After the pump body 8 is started, it pumps out the sludge and discharges it to the designated treatment area. After the sludge scraping task is completed, the operator can turn off the control box 4 and the pump body 8 to stop the sludge scraper from working.

[0027] In practical use, to further facilitate the lifting of the alarm 5, in this embodiment, the lifting assembly includes a fixed frame 15, a bidirectional screw 16, a second motor 17, a slider 18, a scissor-type connecting rod 19, and a lifting frame 20. The fixed frame 15 is fixedly installed on the top wall of the control box 4. The bidirectional screw 16 is rotatably installed inside the fixed frame 15. One end of the bidirectional screw 16 passes through the side wall of the fixed frame 15 and is fitted with the second motor 17. The sliders 18 are threaded onto both the left and right ends of the bidirectional screw 16. The top walls of the two sets of sliders 18 are respectively fixed to the bottom ends of the scissor-type connecting rod 19. The lifting frame 20 is slidably mounted on the top of the scissor-type connecting rod 19, and the alarm 5 is mounted on the top of the lifting frame 20. The control box 4 receives a signal to control the second motor 17 to drive the rotation of the bidirectional screw 16, which allows the sliders 18 at the left and right ends to move relative to or opposite to each other along the thread direction of the bidirectional screw 16. Since the sliders 18 are fixedly connected to the bottom ends of the scissor-type connecting rod 19, the movement of the sliders 18 will cause the scissor-type connecting rod 19 to expand or contract, thereby realizing the smooth lifting and lowering of the lifting frame 20. This design can ensure that the alarm 5 remains stable during the rising process and avoids shaking or tilting.

[0028] In practical use, to further ensure the stable rise of the lifting frame 20, in this embodiment, a guide rod 21 is fixedly installed inside the lifting frame 20, and guide blocks 22 are slidably installed at the left and right ends of the guide rod 21. The bottom walls of the two sets of guide blocks 22 are respectively fixedly connected to the top ends of the scissor-type connecting rod 19. The combination of the guide rod 21 and the guide blocks 22 provides additional guidance and support for the rise of the lifting frame 20. During the process of the scissor-type connecting rod 19 driving the lifting frame 20 to rise, the guide blocks 22 slide along the guide rod 21, limiting the swaying and deviation of the lifting frame 20, thereby enhancing its stability and reducing the safety hazards caused by swaying.

[0029] Preferably, in this embodiment, a connecting rod 23 is horizontally welded to the lower part of several of the vertical rods 12. A side scraper 24 is installed at the end of the connecting rod 23 away from the fixed pile 9. The design of the side scraper 24 allows it to fit tightly against the side wall of the sedimentation tank 1, thereby effectively scraping off the sludge attached to the side wall during the sludge scraping process. This design improves the efficiency and effect of sludge scraping, reduces the residue of sludge on the side wall, and helps to maintain the cleanliness and normal operation of the sedimentation tank 1.

[0030] In actual use, to further ensure the stability and accuracy of the operation of the first motor 3 and the second motor 17, in this embodiment, the first motor 3 and the second motor 17 are servo motors. Servo motors can control position, speed and torque with high precision. Servo motors adopt closed-loop control, which has good stability and can avoid problems such as stalling and vibration, thus ensuring the stability and accuracy of the operation of the first motor 3 and the second motor 17.

[0031] Preferably, in this embodiment, the bottom scraper 13 and the side scraper 24 are both made of carbon steel. Carbon steel has high strength and can withstand large loads and forces. The bottom scraper 13 and the side scraper 24 made of carbon steel can effectively scrape off the sludge deposited on the bottom or side wall of the pool without easily deforming or being damaged.

[0032] In practical use, to further enhance the connection strength between each group of vertical plates, in this embodiment, a reinforcing rod 25 is installed between each group of adjacent vertical rods 12. The reinforcing rod 25 can enhance the connection strength between the vertical rods 12, making the overall structure more stable. The reinforcing rod 25 can also increase the load-bearing capacity of the structure, enabling it to bear greater weight. When subjected to external forces, the reinforcing rod 25 can also disperse and resist these forces, reducing the risk of structural deformation and damage.

[0033] Preferably, in this embodiment, the alarm 5 consists of a buzzer and an alarm light. The buzzer can emit an audible alarm, while the alarm light can emit a visual alarm. This dual warning method can more effectively attract people's attention and ensure that people can be quickly alerted in an emergency.

[0034] To illustrate the possible application scenarios, technical principles, implementable specific solutions, and achievable objectives and effects of this application in detail, the following description, in conjunction with the listed specific embodiments and accompanying drawings, provides a detailed explanation. The embodiments described herein are merely illustrative of the technical solutions of this application and are therefore intended to limit the scope of protection of this application.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
