Description

Technical Field

[0001] The invention relates to the technical field of high-pressure flushing equipment for sanitation cleaning equipment, and in particular to a high-pressure flushing active avoidance device for a sanitation vehicle and an avoidance method thereof. Background Art

[0002] Nowadays, sweepers and sanitation vehicles have been widely used by sanitation, cleaning, property and corporate units. During the cleaning operation, sanitation vehicles need to constantly adjust the cleaning direction according to the shape of the curb. When turning or there are protrusions on the roadside, sanitation vehicles will inevitably collide with the bottom high-pressure washing nozzles. In order to avoid damage to the bottom high-pressure washing components, the high-pressure washing nozzles need to be equipped with an active avoidance function to protect the safety and integrity of the bottom high-pressure washing nozzles.

[0003] The existing high-pressure flushing active avoidance device of sanitation vehicles has the following defects:

However, the device for high-pressure washing of the road surface by the water sprinkler truck in the above document lacks an active avoidance device, which may easily cause the high-pressure washing device to be damaged by collision during use;

[0005] 2. Application document JP2012055290A discloses a cleaning device, but the cleaning water spray pipe in the above document lacks an alarm device that can remind the staff when it leaves the working position during the working process;

[0006] 3. Application document JP2003253894A discloses an accessory cleaner. However, when the accessory cleaner in the above document is out of the working position during operation, the staff needs to manually adjust it to the working position, which easily leads to the technical problem of reduced work efficiency.

[0007] 4. Patent document CN113106905B discloses a high-pressure flushing device for cleaning sanitation facilities.

[0019] Preferably, the avoidance steps of the high-pressure washing active avoidance device of the sanitation vehicle are as follows:

[0020] S1. The driver steps on the locking pedal weldment to separate the fixed tooth plate from the inner wall of the tooth groove. The setting of the limiting hole and the hinged hole bolt enables the high-pressure flushing active avoidance device to descend to the working position under gravity conditions. The equipment moves forward. When encountering an obstacle, the silent wheel, the arc-shaped limit groove and the guide positioning pin are set. When encountering an obstacle, the silent wheel can adaptively swing backward to avoid the obstacle. The arc-shaped limit groove and the guide positioning pin can limit the range of the rear swing. The setting of the limiting rod and the reset torsion spring drives the fixed tooth plate to be inserted into the tooth groove, and the position of the high-pressure flushing active avoidance device is limited and fixed. After passing the obstacle, the driver steps on the locking pedal weldment again to return the high-pressure flushing active avoidance device to the working position under gravity conditions;

[0021] S2. Through the setting of the baffle, the laser displacement sensor and the spray rod upper bracket weldment, the displacement distance of the spray rod upper bracket weldment can be monitored in real time through the laser displacement sensor. After detecting that the displacement distance of the spray rod upper bracket weldment exceeds the set range, the laser displacement sensor can send the detected information to the microcontroller module through the data transmission module. After receiving the information for 3 seconds, the microcontroller module controls the alarm speaker to sound an alarm, so as to remind the driver that the high-pressure washing active avoidance device has actively avoided and is no longer in the working position;

[0022] S3. Within 5 seconds after the microcontroller module controls the alarm speaker to sound an alarm to the driver, the laser displacement sensor will be used for continuous monitoring. If the high-pressure flushing active avoidance device does not return to the working position after 5 seconds, the microcontroller module can control the servo motor to drive the collection roller to rotate. The collection roller rotation can reel in the rope, thereby pulling the rope to move. The rope movement can drive the fixed block to move, thereby driving the fixed tooth plate to move, so that the fixed tooth plate is separated from the tooth groove. Under gravity conditions, the high-pressure flushing active avoidance device will return to the working position, the servo motor will stop working, and the reset torsion spring will drive the fixed tooth plate to insert into the tooth groove.

[0023] S4. By installing one end of the water pipe with one end of the water pipe joint, and then placing the water pipe on the protective cushion, the water pipe can be fixed and clamped by using the first plastic single-hole pipe clamp, the connecting block, the fixing hole and the fixing bolt to ensure the stability of the water pipe and avoid the water pipe from falling off in the case of active avoidance, thereby ensuring the stability of high-pressure flushing.

[0024] Preferably, the step S1 also includes the following steps:

[0025] S11. The height of the high-pressure flushing active avoidance device can be adjusted through the waist holes reserved in the spray boom upper bracket weldment and the spray boom bracket weldment;

[0026] S12. After the work is finished, turn off the power of the sanitation vehicle, and push the high-pressure flushing active avoidance device upward with your hands or feet. Through the setting of the limiting rod and the reset torsion spring, the reset torsion spring drives the fixed tooth plate to be inserted into the tooth groove, and the position of the high-pressure flushing active avoidance device is restricted and fixed, so that the high-pressure flushing active avoidance device will not slide down by itself;

[0027] The step S2 also includes the following steps:

[0028] S21. When encountering a small obstacle, the distance detected by the laser displacement sensor is obtained through the acquisition module, and the data is transmitted to the detection module for detection to ensure the accuracy of the data obtained by the laser displacement sensor. Then, the judgment module is used to judge whether the displacement distance of the high-pressure flushing active avoidance device will affect the high-pressure flushing, and the judgment result is sent to the microcontroller module. If the judgment result is that it will have an impact, an alarm sound is issued through the alarm speaker. If the judgment result is that it will not have an impact, the alarm speaker will not make a sound, and the servo motor will not be controlled to work;

[0029] The step S3 also includes the following steps:

[0030] S31, the high-pressure flushing active avoidance device does not return to the working position, indicating that there is still an obstacle at the bottom of the high-pressure flushing active avoidance device. After the servo motor works for 3 seconds, the microcontroller module will turn off the servo motor, and the reset torsion spring drives the fixed tooth plate to insert into the tooth groove, restricting and fixing the high-pressure flushing active avoidance device, and continuing to detect through the laser displacement sensor, sending data through the data transmission module, repeating the above work content, which can serve to repeatedly remind the driver or the driver forgets to step on the locking pedal weldment, and automatically adjust the high-pressure flushing active avoidance device to return to the working position;

[0031] The step S4 also includes the following steps:

[0032] S41. Through the setting of the fixed frame, the second plastic single-hole pipe clamp, the limiting groove and the limiting block, rotating the threaded rod can drive the threaded rod and the limiting block to move, and the movement of the limiting block can drive the second plastic single-hole pipe clamp to move. The fixed frame can limit the rotation of the second plastic single-hole pipe clamp, and then the second plastic single-hole pipe clamp is driven to clamp and limit the water pipe by rotating the threaded rod.

[0033] Compared with the prior art, the present invention has the following beneficial effects:

[0034] 1. The present invention sets a silent wheel, and the equipment moves forward. When encountering an obstacle, the silent wheel can adaptively swing backward to avoid the obstacle through the setting of the silent wheel, the arc-shaped limit groove and the guide positioning pin. The arc-shaped limit groove and the guide positioning pin can limit the range of the backward swing. Through the setting of the limiting rod and the reset torsion spring, the reset torsion spring drives the fixed tooth plate to be inserted into the tooth groove, and the high-pressure flushing active avoidance device is limited and fixed. The laser displacement sensor, the acquisition module, the detection module and the judgment module can detect the avoidance distance of the active avoidance device and judge whether the high-pressure flushing active avoidance device needs to be returned to the working position, so as to avoid the need for the staff to frequently step on the locking pedal weldment when encountering a small obstacle, thereby achieving the active avoidance function, facilitating operation, and improving work efficiency.

[0035] 2. The present invention can monitor the displacement distance of the spray rod bracket weldment in real time through the laser displacement sensor through the setting of the baffle plate, the laser displacement sensor and the spray rod bracket weldment, detect and judge the displacement distance through the acquisition module, the detection module and the judgment module, and after judging that the displacement distance of the spray rod bracket weldment exceeds the set range, the judgment data is sent to the microcontroller module through the data transmission module. The microcontroller module obtains the position data again 3 seconds after receiving the information, and detects that the high-pressure flushing active avoidance device has not returned to the working position, and controls the alarm speaker to sound an alarm, so as to remind the driver that the high-pressure flushing active avoidance device has actively avoided and is no longer in the working position;

[0036] 3. The present invention will continuously monitor through the laser displacement sensor within 5 seconds after the microcontroller module controls the alarm speaker to sound an alarm to the driver. If the high-pressure flushing active avoidance device does not return to the working position after 5 seconds, the microcontroller module can control the servo motor to drive the collection roller to rotate. The rotation of the collection roller can reel in the rope, thereby pulling the rope to move. The rope movement can drive the fixed block to move, thereby driving the fixed tooth plate to move, so that the fixed tooth plate is separated from the tooth groove. Under gravity conditions, the high-pressure flushing active avoidance device will return to the working position. After the servo motor has worked for 3 seconds, the microcontroller module will turn off the servo motor, and the reset torsion spring will drive the fixed tooth plate to insert into the tooth groove, so as to restrict and fix the high-pressure flushing active avoidance device. When the driver forgets to step on the locking pedal weldment, the high-pressure flushing active avoidance device can be automatically adjusted to automatically return to the working position.

[0037] 4. The present invention installs one end of the water pipe with one end of the water pipe joint, and then places the water pipe on the protective cushion. By using the first plastic single-hole pipe clamp, the connecting block, the fixing hole and the fixing bolt, the water pipe can be fixed and clamped to ensure the stability of the water pipe and avoid the water pipe from falling off when actively avoiding, thereby ensuring the stability of high-pressure flushing and improving work efficiency.

[0073] Example 6: Please refer to Fig.10 The present invention provides an embodiment: a high-pressure washing active avoidance device for a sanitation vehicle, wherein the avoidance steps of the high-pressure washing active avoidance device for a sanitation vehicle are as follows:

[0074] S1. The driver steps on the locking pedal weldment 16 to separate the fixed tooth plate 15 from the inner wall of the tooth groove 14. The setting of the limiting hole 4 and the hinged hole bolt 5 enables the high-pressure flushing active avoidance device to descend to the working position under gravity conditions. The equipment moves forward. When encountering an obstacle, the silent wheel 8, the arc-shaped limit groove 11 and the guide positioning pin 12 are set, and the silent wheel 8 can adaptively swing backward to avoid the obstacle when encountering the obstacle. The arc-shaped limit groove 11 and the guide positioning pin 12 can limit the range of the backward swing. The setting of the limiting rod 17 and the reset torsion spring 18 drives the fixed tooth plate 15 to be inserted into the tooth groove 14, and the position of the high-pressure flushing active avoidance device is limited and fixed. After passing the obstacle, the driver steps on the locking pedal weldment 16 again to return the high-pressure flushing active avoidance device to the working position under gravity conditions;

[0075] S2. Through the arrangement of the baffle 19, the laser displacement sensor 20 and the spray rod upper bracket weldment 6, the displacement distance of the spray rod upper bracket weldment 6 can be monitored in real time through the laser displacement sensor 20. After detecting that the displacement distance of the spray rod upper bracket weldment 6 exceeds the set range, the laser displacement sensor 20 can send the detected information to the microcontroller module 23 through the data transmission module 21. After receiving the information for 3 seconds, the microcontroller module 23 controls the alarm speaker 22 to sound an alarm, so as to remind the driver that the high-pressure washing active avoidance device has actively avoided and is no longer in the working position;

[0076] S3. Within 5 seconds after the microcontroller module 23 controls the alarm speaker 22 to sound an alarm to the driver, the laser displacement sensor 20 will continuously monitor. If the high-pressure flushing active avoidance device does not return to the working position after 5 seconds, the microcontroller module 23 can control the servo motor 40 to drive the collection roller 41 to rotate. The rotation of the collection roller 41 can reel in the rope 42, thereby pulling the rope 42 to move. The movement of the rope 42 can drive the fixed block 43 to move, thereby driving the fixed tooth plate 15 to move, so that the fixed tooth plate 15 is separated from the tooth groove 14. Under gravity conditions, the high-pressure flushing active avoidance device will return to the working position, the servo motor 40 will stop working, and the reset torsion spring 18 will drive the fixed tooth plate 15 to insert into the tooth groove 14.

[0077] S4. By installing one end of the water pipe 28 with one end of the water pipe joint 25, and then placing the water pipe 28 on the protective cushion 29, the water pipe 28 can be fixed and clamped by using the first plastic single-hole pipe clamp 31, the connecting block 32, the fixing hole 33 and the fixing bolt 34, so as to ensure the stability of the water pipe 28 and avoid the water pipe 28 from falling off in the case of active avoidance, thereby ensuring the stability of high-pressure washing;

[0078] Step S1 also includes the following steps:

[0079] S11, the height of the high-pressure flushing active avoidance device can be adjusted through the waist hole 9 reserved in the spray rod upper bracket weldment 6 and the spray rod bracket weldment 7;

[0080] S12, after the work is finished, turn off the power of the sanitation vehicle, and push the high-pressure flushing active avoidance device upward with your hands or feet. Through the setting of the limiting rod 17 and the reset torsion spring 18, the reset torsion spring 18 drives the fixed tooth plate 15 to be inserted into the tooth groove 14, and the position of the high-pressure flushing active avoidance device is restricted and fixed, so that the high-pressure flushing active avoidance device will not slide down by itself;

[0081] Step S2 also includes the following steps:

[0082] S21, when encountering a small obstacle, the distance detected by the laser displacement sensor 20 is obtained through the acquisition module 44, and the data is transmitted to the detection module 45 for detection to ensure the accuracy of the data obtained by the laser displacement sensor 20, and then the judgment module 46 is used to judge whether the displacement distance of the high-pressure flushing active avoidance device will affect the high-pressure flushing, and the judgment result is sent to the microcontroller module 23. If the judgment result is that it will cause an impact, an alarm sound is issued through the alarm speaker 22, and if the judgment result is that it will not cause an impact, the alarm speaker 22 will not make a sound, and will not control the servo motor 40 to work;

[0083] Step S3 also includes the following steps:

[0084] S31, the high-pressure flushing active avoidance device does not return to the working position, indicating that there is still an obstacle at the bottom of the high-pressure flushing active avoidance device. After the servo motor 40 works for 3 seconds, the microcontroller module 23 will turn off the servo motor 40, and the reset torsion spring 18 drives the fixed tooth plate 15 to insert into the tooth groove 14, restricting and fixing the high-pressure flushing active avoidance device, continuing to detect through the laser displacement sensor 20, sending data through the data transmission module 21, repeating the above work content, which can play a role in repeatedly reminding the driver or when the driver forgets to step on the locking pedal weldment 16, automatically adjusting the high-pressure flushing active avoidance device to return to the working position;

[0085] Step S4 also includes the following steps:

[0086] S41. Through the setting of the fixed frame 35, the second plastic single-hole pipe clamp 36, the limiting groove 37 and the limiting block 38, rotating the threaded rod 39 can drive the threaded rod 39 and the limiting block 38 to move, and the movement of the limiting block 38 can drive the second plastic single-hole pipe clamp 36 to move. The fixed frame 35 can limit the rotation of the second plastic single-hole pipe clamp 36, and then drive the second plastic single-hole pipe clamp 36 to clamp and limit the water pipe 28 by rotating the threaded rod 39.

[0087] Working principle: through the setting of the silent wheel 8, the equipment moves forward. When encountering an obstacle, through the setting of the silent wheel 8, the arc-shaped limit groove 11 and the guide positioning pin 12, the silent wheel 8 can adaptively swing backward to avoid the obstacle. The arc-shaped limit groove 11 and the guide positioning pin 12 can limit the range of the backward swing. Through the setting of the limiting rod 17 and the reset torsion spring 18, the reset torsion spring 18 drives the fixed tooth plate 15 to be inserted into the tooth groove 14, and the high-pressure flushing active avoidance device is restricted and fixed. The laser displacement sensor 20, the acquisition module 44, the detection module 45 and the judgment module 46 can detect the avoidance distance of the active avoidance device and judge whether it is necessary to return the high-pressure flushing active avoidance device to the working position to avoid encountering small obstacles. The staff is required to frequently step on the locking pedal weldment 16 to achieve the active avoidance function, which is convenient for operation and improves work efficiency. Through the setting of the baffle 19, the laser displacement sensor 20 and the spray rod upper bracket weldment 6, the displacement distance of the spray rod upper bracket weldment 6 can be monitored in real time through the laser displacement sensor 20. The displacement distance is detected and judged through the acquisition module 44, the detection module 45 and the judgment module 46. After judging that the displacement distance of the spray rod upper bracket weldment 6 exceeds the set range, the judgment data is sent to the microcontroller module 23 through the data transmission module 21. The microcontroller module 23 obtains the position data again 3 seconds after receiving the information, and detects that the high-pressure flushing active avoidance device has not returned to the working position, and controls the alarm speaker 2 2 issues an alarm sound so as to remind the driver that the high-pressure flushing active avoidance device has actively avoided and is no longer in the working position. Within 5 seconds after the microcontroller module 23 controls the alarm speaker 22 to issue an alarm sound to the driver, continuous monitoring will be performed through the laser displacement sensor 20. If the high-pressure flushing active avoidance device does not return to the working position after 5 seconds, the microcontroller module 23 can control the servo motor 40 to drive the collection roller 41 to rotate. The rotation of the collection roller 41 can reel in the rope 42, thereby pulling the rope 42 to move. The movement of the rope 42 can drive the fixed block 43 to move, thereby driving the fixed tooth plate 15 to move, so that the fixed tooth plate 15 is separated from the tooth groove 14. Under gravity conditions, the high-pressure flushing active avoidance device will return to the working position. The servo motor 40 is in the working position. After working for 3 seconds, the microcontroller module 23 will turn off the servo motor 40, and the reset torsion spring 18 drives the fixed tooth plate 15 to be inserted into the tooth groove 14, so as to limit and fix the high-pressure flushing active avoidance device. When the driver forgets to step on the locking pedal weldment 16, the high-pressure flushing active avoidance device can be automatically adjusted to automatically return to the working position. By installing one end of the water pipe 28 with one end of the water pipe connector 25, and then placing the water pipe 28 on the protective cushion 29, the water pipe 28 can be fixed and clamped by using the first plastic single-hole pipe clamp 31, the connecting block 32, the fixing hole 33 and the fixing bolt 34 to ensure the stability of the water pipe 28 and avoid the water pipe 28 from falling off when active avoidance is performed.This ensures the stability of high-pressure flushing.
