Description

Technical Field

[0001] This disclosure relates to the field of sweeper technology, specifically to an early warning sweeper. Background Technology

[0002] Chinese patent CN212607746U disclosed on September 17, 2020, a sweeper with excessive wear warning, comprising a central shaft, wherein a blade base is sleeved on the outer edge of the central shaft; a blade is installed on the side of the blade base, wherein a triggering device is installed inside the blade; the triggering device is connected to a control mechanism through a connecting device; a prompting device is provided in the control mechanism; the triggering device is a coil; the control mechanism is a PLC controller; the connecting device is a connecting wire; and the prompting device is an alarm.

[0003] The aforementioned patented blade has a trigger device installed inside. When the blade wears down to the trigger device, it will break off, triggering a warning and prompting the timely replacement of the blade. This saves manpower, is more convenient, and avoids safety hazards caused by failure to replace the blade in time. It can also be implemented using wired or wireless methods, making off-site management and / or unified management more convenient. However, the aforementioned patent still has the following drawbacks:

[0004] Because the aforementioned patent only installs a trigger device inside the blade head, it can only issue a warning when the blade head wears down to the trigger device. However, when the cleaning component gets stuck, cannot rotate, or its rotation speed drops suddenly, the aforementioned patent cannot issue an alarm. This makes it impossible for workers to obtain the actual situation of the cleaning component in a timely manner. When the cleaning component is stuck, the cleaning efficiency on the ice surface is greatly reduced. At the same time, because the cleaning component is stuck by foreign objects, the aforementioned patent cannot issue an alarm signal in time, causing severe wear on the cleaning component and thus shortening its service life.

Detailed Implementation

[0030] like Figures 1-3 As shown, a pre-warning sweeper disclosed herein includes a vehicle body, a sweeping component 1, a drive component, a pre-warning component 2, and a handrail 3;

[0031] The vehicle body includes the base;

[0032] The cleaning assembly 1 is located at the front end of the base and is connected to the base. The cleaning assembly 1 includes a cover 11, a cleaning roller 12, a cleaning wheel 13, a connecting roller 14 and a cleaning tooth 15. The cover 11 is connected to the base, the end of the cleaning roller 12 is connected to the base, and one end of the cleaning roller 12 is connected to the multi-stage transmission mechanism 4.

[0033] A plurality of sweeping wheels 13 are spaced apart along the length of the sweeping shaft, and are coaxial with the sweeping roller 12. Each sweeping wheel 13 has a through hole extending axially along its axis. A plurality of these holes are arranged in a circumferential array around the sweeping wheel 13. A connecting roller 14 passes through the hole, and its end is fixed to the sweeping wheel 13 by a locking mechanism. Sweeping teeth 15 have connecting holes that match the diameter of the sweeping roller 12. The sweeping teeth 15 are connected to the connecting roller 14, and a plurality of sweeping teeth 15 are arranged between adjacent sweeping wheels 13.

[0034] The drive unit is connected to the base, and the drive unit is connected to the cleaning assembly 1 through a multi-stage transmission mechanism 4;

[0035] The warning component 2 includes a power supply, a speed sensor 21, a warning light 22, and an alarm 23;

[0036] The power supply is electrically connected to the speed sensor 21, which is located on the base near the connecting roller 14. The speed sensor 21 is also connected to the warning light 22 and the alarm 23.

[0037] Specifically, the speed sensor 21 can be a Soway SPH318 series speed sensor. This series of sensors features simple structure, small size, reliability, and maintenance-free operation, ensuring that the sweeper will not become too bulky due to the installation of the speed sensor 21. The speed sensor 21 is preferably installed on the base of the vehicle body, near the connecting roller 14. By calculating the speed of the connecting roller 14, it determines whether the speed of the connecting roller 14 has suddenly dropped, and thus determines whether the sweeping assembly 1 is stuck. The speed sensor 21's measurement of speed is existing technology and will not be elaborated further here. When the speed sensor 21 detects a sudden drop in speed, it immediately sends an alarm signal to the warning light 22 and the alarm 23, using audible and visual warnings to remind personnel to check the status of the sweeping assembly 1.

[0038] With the setting of the early warning component 2, the early warning component 2 includes a speed sensor 21. The speed sensor 21 is connected to the warning light 22 and the alarm 23. When the signal sensor detects a sudden drop in speed, it transmits an alarm signal to the warning light 22 and the alarm 23, causing the warning light 22 and the alarm 23 to sound an alarm, reminding the staff to check the cleaning component 1, so as to avoid the cleaning component 1 from getting stuck, which would reduce the cleaning efficiency of the cleaning component 1; at the same time, it can also prevent the cleaning component 1 from being severely worn due to the inability to send an alarm signal in time, which would shorten its service life.

[0039] Furthermore, in order to enable the cleaning component 1 to quickly break ice during the cleaning process, the early warning cleaner described in this disclosure also includes a spraying component 5. A front extension plate 6 is provided at the front end of the base, and the spraying component 5 is located at the front extension plate 6 and connected to the front extension plate 6. The spraying component 5 includes a tank 51, a nozzle, and a pump body 52.

[0040] Pump body 52 is mounted on front extension plate 6 and connected to front extension plate 6. The input end of pump body 52 is connected to tank 51, and the output end of pump body 52 is connected to nozzle. Tank 51 is filled with de-icing agent. Several nozzles are mounted below front extension plate 6 and connected to front extension plate 6 (not shown in the figure).

[0041] Specifically, the nozzle can be welded to the bottom of the front extension plate 6, or it can be connected to the bottom of the front extension plate 6 through conventional fasteners such as screws. The specific connection method can be selected according to the actual situation. The nozzle is connected to the pump body 52. ​​The pump body 52 pumps the de-icing agent in the tank 51 to the nozzle. The nozzle outlet faces the ground and sprays the de-icing agent onto the ice surface. Since the spraying component 5 is located on the front extension plate 6, in front of the sweeping component 1, the de-icing agent slightly melts the ice surface during the operation of the de-icing sweeper, thereby reducing the wear of the sweeping component 1 during the sweeping process.

[0042] By setting up the spraying component 5 and filling the tank 51 of the spraying component 5 with de-icing agent, the de-icing agent is sprayed during the de-icing process, which can effectively prevent re-icing after de-icing; at the same time, because the de-icing agent is sprayed on the ice surface, the surface energy of the ice surface is reduced, making the sweeping component 1 easier to break the ice; thus, the de-icing sweeper of this disclosure can extend the service life of the sweeping component 1 while ensuring the ice breaking efficiency.

[0043] Furthermore, in order to control the rotation speed of the sweeping component 1 and the spraying conditions of the spraying component 5, the early warning sweeper disclosed herein also includes a control component 7, which is a PLC. The control component 7 is mounted on the handrail 3 and connected to the handrail 3. The control component 7 is also signal-connected to the drive component and to the pump body 52.

[0044] By setting up control component 7, operators of the de-icing sweeper disclosed herein can independently control the rotation speed of sweeping component 1 and the spraying status of spraying component 5, thereby enabling operators to better cope with various ice surface conditions.

[0045] Furthermore, in order to improve the effect of the de-icing agent on the ice surface, a heating component is installed inside the tank 51. The heating component is an electric heating wire, which is electrically connected to the control component 7. The operator can control the heating inside the tank 51 through the control component 7, so that the temperature of the de-icing agent is increased. When sprayed, the hotter de-icing agent comes into contact with the ice surface, accelerating the melting of the ice surface, thereby improving the cleaning efficiency of the sweeping component 1. At the same time, because the ice surface melts faster and the ice layer thickness is reduced, the wear of the sweeping component 1 is also reduced.

[0046] Furthermore, the de-icing agent is a sodium chloride solution or a potassium chloride solution.

[0047] Furthermore, the multi-stage transmission mechanism 4 is a two-stage transmission mechanism, including a first transmission shaft 41, a first transmission wheel 42, a first transmission belt 43, a second transmission wheel 44, a second transmission shaft 45, a third transmission wheel 46, a second transmission belt 47, and a fourth transmission wheel 48. One end of the first transmission shaft 41 is connected to the output end of the drive component, and the other end is rotatably connected to the first transmission wheel 42. The first transmission belt 43 is sleeved on the first transmission wheel 42 and the second transmission wheel 44. The second transmission wheel 44 and the third transmission wheel 46 are coaxially arranged. One end of the second transmission wheel 44 and the second transmission shaft 45 is rotatably connected, and the third transmission wheel 46 is rotatably connected to the other end of the second transmission shaft 45. The second transmission belt 47 is sleeved on the third transmission wheel 46 and the fourth transmission wheel 48, and the fourth transmission wheel 48 is rotatably connected to the cleaning roller 12.

[0048] By setting up a multi-stage transmission mechanism 4, the rotation speed of the cleaning component 1 can be increased more quickly, making the de-icing cleaner of the present disclosure start up faster. At the same time, due to the increased rotation speed, the de-icing efficiency is also improved.

[0049] Furthermore, since the ground is very slippery during de-icing, to prevent the pre-warning sweeper of this disclosure from going out of control, the pre-warning sweeper of this disclosure also includes a braking assembly. The vehicle body includes front wheels and rear wheels, and the braking assembly includes a brake lever and brake pads. The brake pads are coaxially mounted with the front wheels, and the brake lever is located at the handlebar 3 and connected to the handlebar 3. The brake lever and brake pads are connected via a brake cable. By setting up the braking assembly, the risk of the de-icing sweeper of this disclosure going out of control is reduced.

[0050] Furthermore, since the cleaning component 1 experiences significant vibration upon contact with the ice surface during de-icing, to reduce the impact of this vibration on the warning sweeper, the warning sweeper of this disclosure further includes a shock-absorbing component. This component includes an elastic element, one end of which is connected to the front wheel, and the other end to the base; the rear wheel is a swivel wheel. The shock-absorbing component enhances the stability of the warning sweeper during de-icing.

[0051] Furthermore, the drive unit is a diesel engine.

[0052] Furthermore, it also includes an oil storage tank 8, which is mounted on the base, connected to the base, and communicates with the drive unit.

[0053] The early warning sweeper disclosed herein includes an early warning component 2. The early warning component 2 includes a speed sensor 21, which is connected to a warning light 22 and an alarm 23. When the signal sensor detects a sudden drop in speed, it transmits an alarm signal to the warning light 22 and the alarm 23, causing them to sound an alarm and reminding staff to check the sweeping component 1. This prevents the sweeping component 1 from jamming, which would reduce its cleaning efficiency. It also prevents the sweeping component 1 from wearing out due to the inability to send an alarm signal in time, thus shortening its service life.

[0054] In the description of this disclosure, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the accompanying drawings and is only for the convenience of describing this disclosure and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this disclosure.

[0055] For those skilled in the art, various other corresponding changes and modifications can be made based on the technical solutions and concepts described above, and all such changes and modifications should fall within the protection scope of the claims disclosed herein.
