Description

Technical Field

[0001] This utility model relates to the technical field of sanitation sweeper equipment, specifically, it relates to an overflow prevention water tank for a sweeper and a sweeper. Background Technology

[0002] Sanitation sweeper trucks, generally referring to road sweepers, washing sweepers, and vacuum trucks, are vehicles that collect road garbage using a combination of sweeping brushes and negative pressure suction, or purely negative pressure suction. Negative pressure suction uses a power unit to drive a high-pressure centrifugal fan, creating negative pressure and airflow at the suction device, i.e., the suction nozzle. This causes the road garbage to reach its suspension velocity and be drawn off the road. After settling and filtration within the sweeper's body, the garbage is collected inside the body, while the clean airflow is discharged to the outside of the vehicle through the fan and the exhaust duct at the end.

[0003] Sweepers rely on airflow for operation. To reduce secondary dust, they usually use water to suppress dust. Therefore, sweepers generally have a water tank structure that can store clean water to provide a water source for the dust suppression water system.

[0004] The capacity of the water tank has a significant impact on the time required for a sweeper to refill water. The larger the capacity, the longer the operation time will be, assuming the same water consumption per minute.

[0005] The volume of the water tank is directly related to its structure. When the water tank is full, water will overflow from its overflow port. At this time, the water level is the same as the overflow port. When the vehicle is moving, when the water surface is wavy, water often overflows from the overflow port, which affects the working experience and wastes water. Utility Model Content

[0006] The purpose of this utility model is to provide an anti-overflow water tank for a sweeper and a sweeper, in order to solve the technical problem in the prior art that when the water tank is full, the water in the water tank will overflow from the overflow port due to the vibration during vehicle operation, thus causing water waste.

[0007] The present invention solves the above problems through the following technical solution:

[0008] An overflow prevention water tank for a sweeper includes: a box-shaped structure with all four sides closed;

[0009] The side of the box-shaped structure is equipped with a water inlet that connects to the inside of the water tank, as well as a low water level sensor that connects to the alarm. The water inlet is used to provide water to the water system installed on the sweeper that requires water.

[0010] The bottom of the box-shaped structure is equipped with a water inlet pipe and an overflow pipe. Water is added to the water tank through the water inlet pipe; the overflow pipe runs through the top and bottom, with its upper end extending into the water tank.

[0011] An overflow sleeve is movably fitted at the upper end of the overflow pipe, and the two ends are connected so that the upper opening of the overflow pipe serves as the overflow port; one end of a cylinder is connected to the side of the overflow sleeve, and the other end of the cylinder is installed inside the top of the box-shaped structure. The cylinder extends and retracts to drive the overflow sleeve to rise and fall at the upper end of the overflow pipe, thereby adjusting the height of the overflow port.

[0012] As a further improvement, a manhole is formed on the top of the box-shaped structure, and a manhole cover is installed on the manhole.

[0013] As a further improvement, the top of the box-shaped structure is also provided with a hoisting structure for hoisting the water tank.

[0014] As a further improvement, a water level gauge is installed on the side of the box-shaped structure facing the driver's cab for observation. The water level gauge and the water tank form a communicating vessel so that the water level position of the water level gauge is consistent with the water level position in the water tank.

[0015] As a further improvement, the bottom of the box-shaped structure is also provided with a cleaning hole, and an openable cleaning cover is provided outside the cleaning hole to facilitate the opening of the cleaning cover to drain the cleaning wastewater.

[0016] As a further improvement, the overflow sleeve is hinged to the cylinder.

[0017] As a further improvement, a sealing ring is provided between the overflow sleeve and the overflow pipe.

[0018] As a further improvement, the bottom of the box-shaped structure is welded with several parallel base frames, and a water tank mounting structure for installing the water tank is provided on the outside of the base frames.

[0019] As a further improvement, a baffle plate is fixed inside the water tank, and through holes are formed on the baffle plate for water flow and personnel to pass through, so as to reduce the impact force of water in the carriage.

[0020] Furthermore, this utility model also solves the above problems through the following technical solutions:

[0021] A sweeper includes an overflow prevention water tank as described above, and a vehicle controller, wherein a cylinder in the water tank communicates with the vehicle controller.

[0022] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0023] (1) This utility model is equipped with a traditional overflow pipe and a movable overflow sleeve is fitted on the upper end of the overflow pipe. The overflow sleeve can move up and down to raise and lower the overflow water level of the water tank, thereby reducing backflow of full water and increasing the effective volume of the water tank.

[0024] (2) This utility model communicates between the vehicle controller and the cylinder, so that during the vehicle's operation, the cylinder automatically lifts the overflow sleeve, increasing the overflow height of the water tank and thus avoiding backflow; when the vehicle stops, the cylinder extends and the overflow sleeve returns to its original position, so that the overflow height of the water tank becomes the normal water filling height, thus realizing normal water filling.

[0031] 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.

[0032] Example:

[0033] like Figure 1-4 As shown, a sweeper's overflow prevention water tank includes: a box-shaped structure with all four sides closed.

[0034] The top of the box-shaped structure has a manhole, and a manhole cover 9 is installed on the manhole so that workers can open the manhole cover 9 and enter the water tank through the manhole. The top of the box-shaped structure is also provided with a hoisting structure 8 for hoisting the water tank. Preferably, there are four hoisting structures 8 arranged in a square.

[0035] The box-shaped structure has a water level gauge 11 on the side facing the cab for the driver to observe. Several water level gauges 11 are arranged vertically, and the upper and lower ends of each water level gauge are connected to the inside of the water tank to form a communicating vessel with the inside of the water tank. This makes the water level position of the water level gauge consistent with the water level position in the water tank, so that the driver can observe the water level in the water level gauge 11 through the rearview mirror and estimate the operation time.

[0036] The box-shaped structure has a water inlet 10 connected to the inside of the water tank and a low water level sensor 13 connected to the alarm on the lower part of the side away from the cab. The water inlet 10 is used to provide water to the water system installed on the sweeper that requires water, such as for cleaning the ground, dust suppression, spraying, etc.

[0037] The bottom of the box-type structure is equipped with a water inlet pipe 6, an overflow pipe 4, and a cleaning hole. The water inlet pipe 6 is connected to the inside of the water tank so that water can be added to the water tank through the water inlet pipe. An openable cleaning cover 12 is provided outside the cleaning hole so that the staff can open the cleaning cover 12 to drain the cleaning wastewater. The overflow pipe 4 runs through the top and bottom, and the upper end extends into the water tank. When water flows out of the lower end of the overflow pipe 4, it will remind the driver that too much water has been added. It can be used to monitor abnormal water levels and issue timely warnings. Of course, other detection devices can also be added. If water is detected flowing out of the lower end of the overflow pipe, a reminder will be given through the display panel or audible and visual alarm in the cab.

[0038] In an optional embodiment, a plurality of parallel base frames 106 are welded to the bottom of the box-shaped structure, and a water tank mounting structure 5 is provided on the outside of the base frames 106 to install the water tank.

[0039] In one specific embodiment, a sweeper's overflow prevention water tank has a box-shaped structure welded from a top plate 101, a bottom plate 104, a front plate 102, a rear plate 103, and a side plate 105, which is rigid and relatively enclosed; a water inlet pipe 6 and an overflow pipe 4 are connected to the inside of the water tank and are disposed on the bottom plate 104, and a water outlet 10 is connected to the inside of the water tank and is disposed on the rear plate 103; a water inlet ball valve can be installed on the water inlet pipe 6 and connected to a water inlet plug through a pipeline; when water is added until the overflow pipe 4 overflows, the water inlet ball valve is closed to complete the water filling.

[0040] A manhole is formed on the top plate 101 of the water tank 1, and a manhole cover 9 is installed on the manhole. During the welding and routine maintenance of the water tank, the manhole cover 9 can be opened to allow workers to enter the water tank through the manhole. A hoisting structure 8 is provided on the top plate 101 of the water tank 1 for the hoisting of the water tank.

[0041] The water tank 1 is equipped with a baffle plate 7 structure to reduce the impact force of water on the side plates 105, front plates 102, and rear plates 103 when the water in the water tank 1 sways from side to side. In this embodiment, the baffle plate 7 structure has several circular holes in the lower and middle parts, and square holes in the upper part. Both the circular and square holes allow water to flow through, and the square holes allow workers to pass through during construction. The baffle plate is installed in the water tank 1 by welding.

[0042] The bottom plate 104 and the base frame 106 of the water tank 1 are welded together. The base frame 106 is equipped with a water tank installation structure 5. The bottom plate 104 is equipped with a cleaning hole. When the staff enters the water tank 1 through the manhole cover 9 to clean it, the cleaning cover 12 of the cleaning hole can be opened to facilitate the discharge of cleaning wastewater.

[0043] A low water level sensor 13 connected to an alarm is installed on the rear panel 103 of the water tank 1. When the water level reaches the sensor position, the system will automatically trigger a water shortage alarm, automatically shut down the vehicle, and remind the driver to add water in time.

[0044] The front panel 102 of the water tank 1 is equipped with at least one water level gauge 11. The upper and lower ends of the water level gauge 11 are connected to the inside of the water tank so that the water level of the water level gauge is consistent with the water level inside the water tank. The driver can observe the water level in the water level gauge 11 through the rearview mirror in order to estimate the operation time.

[0045] An overflow sleeve 3 is provided on the overflow pipe 4. The overflow pipe 4 and the overflow sleeve 3 are vertically connected, so that the upper opening of the overflow pipe replaces the upper end of the overflow pipe 4 as the overflow outlet. One end of the cylinder 2 is connected to the side of the overflow sleeve 3. The cylinder 2 extends and retracts to drive the overflow sleeve 3 to rise and fall. In this embodiment, the side of the overflow sleeve 3 is hinged to one end of the cylinder 2. The upper hinge point mounting bracket at the other end of the cylinder 2 is fixed to the top plate 101 of the water tank 1. The overflow sleeve 3 and the overflow pipe 4 are sleeved together and vertically connected. A sealing ring 14 is provided between the overflow sleeve 3 and the overflow pipe 4 to ensure a seal when they move relative to each other. It is worth noting that when the cylinder 2 drives the overflow sleeve 3 to rise outside the overflow pipe 4, even if the overflow sleeve 3 rises to its highest point, it is still sleeved outside the overflow pipe 4 and will not detach from the overflow pipe 4, so that the height of the overflow sleeve 3 can be used as the overflow height. In order to ensure the stability of the overflow pipe 4, both ends of the overflow pipe 4 are equipped with fixing points to facilitate fixing it inside the water tank 1.

[0046] In an optional embodiment, a sweeper includes the aforementioned overflow prevention water tank and a vehicle controller, wherein cylinder 2 within the water tank communicates with the vehicle controller.

[0047] After the driver completes the water filling process and the vehicle starts moving, the vehicle controller recognizes the vehicle's driving signal and automatically controls cylinder 2 to raise the overflow sleeve 3. At this time, the overflow height of the water tank increases. With the increased overflow height, the effective volume of the water tank increases, and the overflow height is higher than the water level line, effectively preventing backflow during vehicle operation. Of course, the cylinder can also be controlled in other ways.

[0048] When the vehicle stops operating, the vehicle controller recognizes that the vehicle speed is zero, automatically controls cylinder 2 to extend and overflow sleeve 3 to return to its original position. At this time, the overflow height of the water tank becomes the normal water filling height, and the driver can add water normally.

[0049] Although the present invention has been described herein with reference to illustrative embodiments, the above embodiments are merely preferred embodiments of the present invention, and the implementation of the present invention is not limited to the above embodiments. It should be understood that those skilled in the art can devise many other modifications and implementations, which will fall within the scope and spirit of the principles disclosed in this application.
