Description

Technical Field

[0001] The utility model relates to the technical field of sludge removal vehicles, in particular to a siphon sludge removal vehicle with automatic speed regulation, precise positioning and parking. Background Technique

[0002] Through the action of a sludge pump, the sludge settled at the bottom of the pool is pumped to the sludge discharge pipeline on the sludge removal vehicle, and then the sludge is discharged outside the pool. The sludge removal vehicle discharges sludge while driving. The sludge removal vehicle includes a siphon type, a pump suction type, and a pump- siphon two-suction type. Among them, the siphon sludge removal vehicle uses a submersible pump with a water injector or a vacuum pump to form a vacuum, and uses the liquid level difference between the sedimentation tank and the sludge discharge tank for sludge discharge.

[0003] Chinese Patent CN207562415U discloses a sludge removal vehicle with automatic speed change, including a sludge removal vehicle body and a PLC controller; rollers for driving the sludge removal vehicle body to move are arranged on both sides of the bottom of the sludge removal vehicle body, and the rollers are coaxially connected with a driving motor; a support frame for placing the driving motor is arranged at the bottom of the sludge removal vehicle body, a Hall sensor is fixed on one side of the support frame close to the roller, and the Hall sensor is connected to the PLC controller; the driving motor and the roller are connected by a flange, and a magnet sheet is fixed along the radial direction of the flange, and the magnet sheet sweeps across the probe axis of the Hall sensor during rotation; the PLC controller is connected to the driving motor.

[0004] In the above structure, by using the Hall effect, the magnet sheet is driven to rotate by the roller. When the magnet sheet sweeps across the probe of the Hall sensor, the PLC controller calculates the number of turns the roller has traveled, so as to know the running situation of the sludge removal vehicle. However, the traditional positioning method of the sludge removal vehicle mostly relies on mechanical limit switches or manual judgment, and this method has problems such as low positioning accuracy and easy error. Especially in large sedimentation tanks, due to the long length of the tank body, even a small positioning error may lead to poor sludge discharge effect or equipment damage.

By installing positioning modules on the first vehicle body and the second vehicle body, and through the information interaction between the positioning plate module and the controller, the feedback position information is sent in real time. When the specified position is reached, the sludge removal vehicle stops automatically.

[0006] To solve the problems of the existing technology, the utility model provides a siphon sludge removal vehicle with automatic speed regulation, precise positioning and parking, including a first vehicle body and a second vehicle body that moves along the length direction of the first vehicle body.

Detailed Embodiment

[0024] To further understand the features, technical means, specific purposes, and functions achieved by the present utility model, the following further describes the present utility model in detail in conjunction with the accompanying drawings and specific embodiments.

[0025] Referring to Figures 1 - 4 As shown, the present utility model provides a siphon sludge removal vehicle for automatic speed regulation and precise positioning parking, including a first vehicle body 1 and a second vehicle body 4 that moves along the length direction of the first vehicle body 1. The central positions on both sides of the first vehicle body 1 are inlaid with first positioning modules 11 for positioning. The first positioning modules 11 are used to determine the precise position of the first vehicle body 1 in the working environment. The central positions on both sides of the second vehicle body 4 are inlaid with second positioning modules 41 for positioning. The second positioning modules 41 are used to determine the position of the second vehicle body 4. The first positioning modules 11 and the second positioning modules 41 can enable the first vehicle body 1 and the second vehicle body 4 to park precisely at specific positions. A controller (not shown in the figure) for controlling the operation of the first vehicle body 1 and the second vehicle body 4 is also installed on the first vehicle body 1. The controller is responsible for receiving the position information from the first positioning modules 11 and the second positioning modules 41. The controller integrates algorithms and logics inside to process the received data and calculate the control instructions required for the first vehicle body 1 and the second vehicle body 4 to reach specific positions.

[0026] The first positioning modules 11 and the second positioning modules 41 start to work, calculate the positions of the first vehicle body 1 and the second vehicle body 4. The controller calculates the directions and distances that the first vehicle body 1 and the second vehicle body 4 need to move based on these position information and in combination with the preset parking position coordinates. The controller sends control instructions to the actuators of the first vehicle body 1 and the second vehicle body 4 to adjust their speeds and move in the specified directions. During the movement, the controller continuously receives new position information and makes real-time adjustments as needed. When the first vehicle body 1 and the second vehicle body 4 reach the preset parking positions, the controller issues a parking instruction, and the actuators stop working, and the device realizes precise parking.

[0027] The first positioning modules 11 and the second positioning modules 41 can obtain the position information of the sludge removal vehicle in real time, record the movement trajectory of the sludge removal vehicle, and perform information interaction with the controller. When the sludge removal vehicle reaches the specified position, the sludge removal vehicle automatically parks, solving the problem of inaccurate judgment in manual operation.

[0028] A first guide rail 2 is also provided at the bottom of the first vehicle body 1. The material of the first guide rail 2 should have good wear resistance, corrosion resistance and sufficient strength to withstand the weight of the first vehicle body 1 and the impact force during movement. The first guide rail 2 is pre-installed on the sedimentation tank. The bottom of the first vehicle body 1 is also fixed with a first running wheel 12 for driving the first vehicle body 1 to run along the length direction of the first guide rail 2. The first running wheel 12 cooperates with the first vehicle body 1. A first driving mechanism 13 for driving the first running wheel 12 to rotate is also installed at the bottom of the first vehicle body 1. The first driving mechanism 13 can be an electric motor, a hydraulic motor or a pneumatic motor, etc. The specific type depends on the design requirements, working environment and energy supply of the equipment. The first driving mechanism 13 receives instructions through the controller and adjusts the output torque and speed according to the instructions to achieve precise movement and positioning of the first vehicle body 1.

[0029] When the first vehicle body 1 needs to be moved, the controller sends a start command to the first drive mechanism 13. After receiving the command, the first drive mechanism 13 starts working and drives the first running wheel 12 to rotate. Under the rolling action of the first running wheel 12, the first vehicle body 1 moves along the length direction of the first guide rail 2. During the movement, the controller adjusts the output of the drive mechanism in real time according to the position information of the first positioning module 11 to ensure that the first vehicle body 1 can be accurately docked at the predetermined position.

[0030] refer to Figure 5 As shown, a second guide rail 5 is fixed to the top of the first vehicle body 1 along its length, providing a running track for the second vehicle body 4. Second running wheels 44 are rotatably provided on both sides of the bottom of the second vehicle body 4 for enabling the second vehicle body 4 to run. The second running wheels 44 cooperate with the second guide rail 5. A second drive mechanism 441 is also mounted on the bottom of the second vehicle body 4 to drive the second running wheels 44. The second drive mechanism 441 can be an electric motor, hydraulic motor, or pneumatic motor. The specific type depends on the design requirements, working environment, and energy supply of the equipment.

[0031] When the second vehicle body 4 needs to be moved, the controller sends a start command to the second drive mechanism 441. Upon receiving the command, the second drive mechanism 441 begins to operate, driving the second running wheels 44 to rotate. Under the rolling action of the second running wheels 44, the second vehicle body 4 moves along the length of the second guide rail 5. During this movement, the controller adjusts the output of the second drive mechanism 441 in real time based on the second positioning module 41 to ensure that the second vehicle body 4 can accurately dock at the predetermined position. At the same time, the coordinated operation between the first positioning module 11 and the second positioning module 41 also helps to improve the positioning accuracy of the entire device.

[0032] refer to Figure 6As shown in the figure, a speed detection component 3 is correspondingly arranged at a position near the first traveling wheel 12 at the bottom of the first vehicle body 1, and a speed detection component 3 is also correspondingly arranged at a position near the second traveling wheel 44 at the bottom of the second vehicle body 4. The speed detection component 3 is used to detect the rotation speeds of the first traveling wheel 12 and the second traveling wheel 44, and feed the rotation speed signals back to the controller on the first vehicle body 1 for accurately controlling the moving speeds of the first vehicle body 1 and the second vehicle body 4. The speed detection component 3 includes a photoelectric sensor 31 and a light emitter 32. The light emitter 32 is respectively installed on the first traveling wheel 12 and the second traveling wheel 44. The light emitted by the light emitter 32 is received by the photoelectric sensor 31. When the first traveling wheel 12 and the second traveling wheel 44 rotate one circle each, the photoelectric sensor 31 detects and receives the light signal emitted by the light emitter 32 once.

[0033] When the first traveling wheel 12 or the second traveling wheel 44 starts to rotate, the light emitter 32 installed on it will rotate accordingly and emit light. These lights are received by the photoelectric sensor 31 fixed on the vehicle body. Every time the traveling wheel rotates one circle, the light emitter 32 will pass through the detection area of the photoelectric sensor 31 once, thereby triggering the photoelectric sensor 31 to generate a light signal reception event. By calculating the number of light signals received by the photoelectric sensor 31 within a unit time, the rotation speed of the traveling wheel can be accurately calculated, so as to automatically control the speed of the sludge removal vehicle.

[0034] Reference Figure 5 As shown in the figure, a connecting piece 42 is also fixed at the bottom of the second vehicle body 4. A lifting frame 43 is slidably arranged on the connecting piece 42, and a telescopic driving member 434 for driving the lifting frame 43 to move up and down is also installed between the connecting piece 42 and the lifting frame 43 for driving the lifting frame 43 to move up and down. The telescopic driving member 434 can accurately adjust the position of the lifting frame 43 according to the instructions of the controller. A sludge suction pump 431 is fixed at the bottom of the lifting frame 43, and a main pipeline 432 is also fixed at the bottom of the outer shell of the sludge suction pump 431. A sludge discharge pipe is connected to the outlet of the sludge suction pump 431. The sludge suction pump 431 is the core component of sludge treatment. It sucks sludge by generating negative pressure and transports it to a designated position through a pipeline. A stirring blade 433 for stirring the sludge is also connected to the sludge suction pump 431 through a shaft. The stirring blade 433 rotates with the operation of the sludge suction pump 431, generating a stirring effect, which helps the sludge suction pump 431 to suck out the sludge.

It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the appended claims.
